Full textAbstract:
The cross-stitch peripheral suture has good strength, but the large amount of exposed suture on the tendon surface has restricted its clinical usage. We report a method of embedded cross-stitch that incorporates cross-stitches into peripheral sutures and reduces the amount of exposed suture on the tendon surface. Thirty-three fresh pig flexor tendons were divided equally into three groups and repaired with cross-stitch, embedded cross-stitch, or modified Halsted sutures. The tendons were tested in an Instron tensile machine to assess the mechanical performance of these repairs. With an identical number of strands across the repair site, the gap formation and ultimate forces of the embedded cross-stitch method were statistically greater than those of the cross-stitch and modified Halsted methods. The embedded cross-stitch method also had significantly greater stiffness and energy to failure than the cross-stitch method. The embedded cross-stitch method, with little suture exposure on the tendon and sufficient strength, presents an alternative to the current cross-stitch peripheral repair.

Full textAbstract:
Background: Given the variety of suturing techniques for bucket-handle meniscal repair, it is important to assess which suturing technique best restores native biomechanics. Purpose/Hypothesis: To biomechanically compare vertical mattress and cross-stitch suture techniques, in single- and double-row configurations, in their ability to restore native knee kinematics in a bucket-handle medial meniscal tear model. The hypothesis was that there would be no difference between the vertical mattress and cross-stitch double-row suture techniques but that the double-row technique would provide significantly improved biomechanical parameters versus the single-row technique. Study Design: Controlled laboratory study. Methods: Ten matched pairs of human cadaver knees were randomly assigned to the vertical mattress (n = 10) or cross-stitch (n = 10) repair group. Each knee underwent 4 consecutive testing conditions: (1) intact, (2) displaced bucket-handle tear, (3) single-row suture configuration on the femoral meniscus surface, and (4) double-row suture configuration (repair of femoral and tibial meniscus surfaces). Knees were loaded with a 1000-N axial compressive force at 0°, 30°, 60°, 90°, and 120° of flexion for each condition. Resultant medial compartment contact area, average contact pressure, and peak contact pressure data were recorded. Results: Intact state contact area was not restored at 0° ( P = .027) for the vertical double-row configuration and at 0° ( P = .032), 60° ( P < .001), and 90° ( P = .007) of flexion for the cross-stitch double-row configuration. No significant differences were found in the average contact pressure and peak contact pressure between the intact state and the vertical mattress and cross-stitch repairs with single- and double-row configurations at any flexion angles. When the vertical and cross-stich repairs were compared across all flexion angles, no significant differences were observed in single-row configurations, but in double-row configurations, cross-stitch repair resulted in a significantly decreased contact area, average contact pressure, and peak contact pressure (all P < .001). Conclusion: Single- and double-row configurations of the vertical mattress and cross-stitch inside-out meniscal repair techniques restored native tibiofemoral pressure after a medial meniscal bucket-handle tear at all assessed knee flexion angles. Despite decreased contact area with a double-row configuration, mainly related to the cross-stitch repair, in comparison with the intact state, the cross-stitch double-row repair led to decreased pressure as compared with the vertical double-row repair. These findings are applicable only at the time of the surgery, as the biological effects of healing were not considered. Clinical Relevance: Medial meniscal bucket-handle tears may be repaired with the single- or double-row configuration of vertical mattress or cross-stitch sutures.

Full textAbstract:
The purpose of this article is to assist engineers in making quick decisions to improve the strength of single jersey knit fabric. This article focused on the different parameters of the single jersey knit fabrics (like stitch length, yarn count, GSM, tightness factor, and fabric thickness) are considered to know their influence on the bursting strength. Five hypotheses have been developed for plain, pique, and fleece knits. Analyses of Variance (ANOVA), correlation coefficient, and regression analysis are executed using the STATA 14.1 program to test the hypotheses at a 5% level of significance. Three of the five hypotheses are rejected. This study supports that the bursting strength of the fabric is dependent on the tightness factor, stitch length, and count of the single jersey knitted fabrics. Here, the stitch length, count, and tightness factor are inversely proportional to the bursting strength. The GSM and fabric thickness have less impact on the bursting strength.

Postoperative staple-line bleeding after stapled hemorrhoidopexy represents a major issue of this procedure, especially in the day surgery setting. In this study we assess the possible benefit of using circular bioabsorbable staple-line reinforcement to reduce the risk of hemorrhage when performing stapled hemorrhoidopexy in a day surgery setting. Patients with symptomatic II to III grade hemorrhoidal disease were randomly assigned into two groups. In Group A we performed a stapled hemorrhoidopexy using PPH33-03® with Seamguard®, a bioabsorbable staple-line reinforcement; in Group B, we used only a PPH33-03® stapler. We evaluated the intraoperative and postoperative staple-line bleeding and, secondarily, the duration of surgery, need for additional hemostatic stitches, and presence of postoperative complications. One hundred patients were enrolled in the study. Group A patients showed a statistically significant decrease of intraoperative bleeding (4 vs 42% in Group B) and hemostatic stitch placement (5.7 vs 42%) with the consequent reduction in mean operative time, postoperative pain, and tenesmus. There were no differences between the two groups in hemorrhoidal disease control or postoperative late complications. The use of bioabsorbable staple-line reinforcement while performing stapled hemorrhoidopexy may allow improvement of the safety of this procedure, especially in a day surgery setting.

ABSTRACT
Introduction: Long Leg View is an x-ray examination of all parts of the lower extremity using a long vertical cassette which aims to measure the angle between the mechanical axis of the femur and tibia. Knee Joint examination with indications of osteoarthritis at the Radiology Installation of RSUP Dr. Sardjito Yogyakarta uses supine AP projection, Lateral recumbent, Skyline, and Stitch View Long Leg.
Methods: This research is a qualitative research with a case study approach. Collecting data by means of observation, documentation, and in-depth interviews with patients, sending doctors, radiologists, and radiographers. Data collection was carried out in March 2018 at the Radiology Installation of Dr. RSUP. Sardjito Yogyakarta. The data obtained were analyzed using an interactive model.
Results: On the Stitch View Long Leg examination at the Radiology Installation, Dr. Sardjito Yogyakarta uses a collimation area from the pelvis to the ankle joint. According to the resident doctor of orthopedic surgery and traumatology, Dr. Sardjito Yogyakarta, Stitch View Long Leg is able to see the shape of the foot formation, namely the O formation or X formation. In addition, according to radiology specialists, looking at the alignment deviation of the lower extremities can be used to assess the grade of osteoarthritis. Under normal conditions, the anatomical axis of the femur and tibia forms an angle of 6º ± 2º, while the mechanical axis line under normal conditions is 8 mm ± 7 mm medial to the center of the knee joint line. The alignment of varus and valgus has been associated with the development of medial or lateral osteoarthritis.
Conclusion: Stitch View Long Leg aims to assess the grade of osteoarthritis through assessment of lower extremity alignment deviations, see the overall mechanical and anatomical alignment of the lower extremities, help determine the calculation of the angle of bone cutting during Total Knee Replacement surgery, and see the right and left symmetrical balance of genu.

Full textAbstract:
Objective To assess the value of transvaginal ultrasound parameters after cerclage placement in estimating the risk of spontaneous preterm birth. Study Design This is a retrospective cohort at a single tertiary care center from 2013 to 2016. Women carrying a singleton, nonanomalous fetus with cerclage in situ and at least one postcerclage transvaginal ultrasound from 160/7 to 256/7 weeks' gestation were included. In addition to abstracting maternal demographic and obstetric characteristics, two study investigators separately reviewed each of the images from the first transvaginal ultrasound after cerclage placement, masked to pregnancy outcomes. We measured the angle between the anterior uterine wall and cervical canal at the internal os and external os, closed canal length above and below the stitch, width of the anterior and posterior cervix at the level of the cerclage, and stitch distance from the cervical canal. The presence of additional ultrasound findings such as sludge and cervical funneling was also noted. The main outcomes were preterm birth < 34 weeks and preterm birth < 37 weeks. Transvaginal ultrasound parameters were compared between women with preterm birth and those without preterm birth using chi-square, Fisher's exact, and Wilcoxon's rank-sum tests, as appropriate. Log binomial regression was used to estimate the relative risk of preterm birth for all significant obstetric and ultrasound characteristics. Results A total of 102 women met inclusion criteria: 58% had history-indicated, 20% ultrasound-indicated, and 23% exam-indicated cerclages. Of these, 28 (27.5%) women delivered at < 34 weeks' gestation, and 48 (47.0%) women delivered at < 37 weeks' gestation. Preterm birth did not vary by race, maternal age, insurance, smoking, or gestational age of the earliest prior preterm birth (for multiparous women), but women who had preterm birth were more likely to have exam-indicated cerclage. There were several transvaginal ultrasound parameters associated with preterm birth < 34 weeks and preterm birth < 37 weeks. Of these, cervical length below the stitch, stitch distance from the cervical canal, straight cervical canal, funneling to or past the stitch, and presence of sludge had the greatest effect sizes. Conclusion Rates of preterm birth are high postcerclage. In addition to measuring cervical length, utilization of postcerclage transvaginal ultrasound to evaluate the location of the cerclage within the cervix, the curvature of the cervical canal, and the presence of funneling and sludge may help identify women who are at the highest risk for preterm birth.

Full textAbstract:
Precast concrete building cores are a widely used lateral load resisting system in low and mid-rise multi-storey buildings. However, despite their widespread use in countries like Australia or New Zealand, a very little research or experimental testing has been undertaken to assess their lateral drift behaviour. This article will present the findings and observations of a recent experimental testing programme into reinforced concrete precast building cores, which included three large-scale ‘box-shaped’ precast building core specimens. Adjacent panels in each specimen were connected together using welded stitch plate connections and then connected to foundation blocks on the top and bottom using grout tube connections. The results of the testing showed that the welded stitch plate connections were too flexible to allow full composite action to be developed in the cross-section, which meant the precast building core specimens were around 25% more flexible than an equivalent cast in-situ version. The testing also highlighted common detailing and construction deficiencies that can severely inhibit the ductility of the core.

To determine the effect of nanosized organosilicon softeners on the indices of the technological properties of a knitted fabric, to assess the possibility of their improvement through the use of innovative finishing processing. Theoretical and experimental studies are based on the basic principles of textile materials science. In experimental studies, standardized methods and techniques were used, which are reflected in the laboratory by providing softening treatment for knitted fabrics. The sewing process was performed on a Juki DLL-8100e industrial sewing machine. The stitch frequency of the stitches was determined by the registration method. It is determined that the use of nanosized organosilicon softeners significantly affects the performance of the technological properties of a knitted fabric. It was found that the Kolosil nanosized organosilicon softener, which was used by the selection method at a concentration of 4% of the processed material, has a maximum effect on the total deformation and increases the proportion of the slowly inverse deformation component. It is shown that the use of softeners has a positive effect on the stability of the linear dimensions of a knitted fabric. It is proved that the final processing of knitted fabric with innovative nanosized organosilicon softeners can be considered a factor in reducing the technological complexity of garments. The scientific hypothesis has been experimentally confirmed in the use of nanosized organosilicon softeners to improve the indicators of the technological properties of a knitted fabric. It is shown that treatment with nanoscale softeners causes changes in the structure of fibers at the micro level, which are of paramount importance for the formation of technological properties of a knitted fabric. The research results can be used in the development of new materials with improved properties, in the design of clothing parts and in sewing knitted fabrics.

Traditional choliof Haryana,locally known as aangi,is rare to be seen in today’s time. This upper garment was worn by women before the adoption of kurta. It was tied at back with two pairs of strings and worn by teaming with daaman. It was usually stitched by using ten to twelve pieces of fabric. Aangis were usually multicolored as these were made from various leftover fabric pieces available at home. That is why they sometimes lacked any symmetry of colour. These different pieces were joined together by finishing the seams with magji, rick-rack, gotta or embroidery to give it a unified look. A lot oftime was spent in preparation and decoration of this attire. Aangi was a highly intricate garment depicting the talent of women in this craft. The present study was conducted to assess the market potential of this traditional choli of Haryana in thismodern era.For this purposeanaangiblouse was constructed by the researcher in which constructional features of the traditional aangiwere incorporated. Cotton blend fabrics of yellow, red and blue colours were used as base material while herring bone stitch and mirrors were used for embellishmentas per experts’ suggestions. The aangiblousewas assessed for marketability by 200 respondents including Indian as well as foreign visitors and stall owners/exporters in the International Trade Fair, Delhi. Acceptability of aangiblouse was found to be excellent on all parameters i.e., traditional value (WMS 3.89), aesthetic appeal (WMS 3.75), workmanship (WMS 3.69), colour combination (WMS 3.67), utility (WMS 3.64) uniqueness (WMS 3.57) and fabric (WMS 3.41). On an average acceptability was found to be excellent.This aangiblouse can be teamed with a transparent saree for creating a unique style statement.Some respondents suggested to modify aangi as top or to use original form of aangi under transparent top.

Objectives: Some studies have shown that rhabdosphincter reconstruction provides an earlier return to continence after radical prostatectomy. We aim to study the impact of this procedure in urinary continence along with comparing two specific surgical techniques for posterior reconstruction. Materials and methods: We studied a group of patients who were submitted to LRP with No Rhabdosphincter Reconstruction (NRR) and another group with Posterior Reconstruction of the Rhabdosphincter (PRR). The latter was further divided into two groups: "Rocco type stitch" group and "Bollens type stitch" group. We used three questionnaires (IIEF-5, ICIQ-SF and IPSS) to assess urinary continence and erectile function 90 days after surgery. Results: Patients of PRR group had a better full continence rate than patients of NRR group at 90 days (96.6% vs 33.3%, p < 0.001). Concerning urinary incontinence (p = 0.116), lower urinary tract symptoms (p = 0.543) and postoperative complication rates (p = 0.738), our results suggested that there were no differences between the techniques studied. Conclusions: Posterior reconstruction of the rhabdosphincter has significant benefits for urinary continence recovery on patients undergoing radical prostatectomy. No differences were observed in continence recovery between the two techniques analyzed. Additionally, reconstruction of the rhabdosphincter appears to be a safe procedure with no increased risk of postoperative complications.

Full textAbstract:
Textile reinforced concrete (TRC) is a sustainable composite material consisting of a cementitious based matrix in combination with an open meshed technical textile reinforcement made of carbon or glass fibres. In the future, TRC could be increasingly used in the form of double-curved concrete elements with the aim of producing filigree yet load-bearing concrete shell structures. To assess whether a textile is suitable as a reinforcement structure in double-curved textile concrete elements, numerous properties need to be investigated and evaluated. The most important of these include good handling properties, bending stiffness tailored to the application, sufficiently pronounced mesh openings, and defect-free drapability. In the course of this work, biaxially reinforced knitted fabrics with five different stitch types (pillar open, pillar closed, tricot counterlaid, tricot closed and plain) were investigated to evaluate the above properties. The draping tests were conducted on a robot-controlled draping test apparatus and evaluated with the aid of an optical measuring system. In addition, the geometric relationship between surface curvature of the double curved elements and the shear angle of different textiles was used to classify the influence of the stitch type on the drapability. Finally, for a given double curved geometry, based on the results the selection of an appropriate textile reinforcement which fulfil the component requirements is carried out and a double curved TRC demonstrator element is prefabricated.

This study investigates to turn the stomach of cow into exotic leather and then leather products that would add value to the end of leather industry. For this purpose, three pieces of cow stomachs are taken to convert into leather through pre-tanning, tanning and post tanning operations i.e. soaking, liming, deliming, bating, pickling, tanning, retanning, dyeing, fatliquoring, finishing etc. Some mechanical operations are also carried out, such as drying and stacking. Several mechanical investigations have been conducted, including tensile strength, stitch tear strength colour rub fastness and shrinkage temperature in order to assess the overall physical properties of prepared leather. Chemical analyses have also been carried out (chromic oxide content, fat content and pH) to find out the quality of leather. It is observed that tensile and stitch tear strengths are much lower than any of the grained upper leather. But the results demonstrate that colour rub fastness is good enough to meet the standard value. Among the different chemical analyses, pH and % of fat content meet the standard value, but chromic oxide content (%) of one sample is below than the standard value of grained upper leather. All these might be due to the prevalence of difference in composition between hide/skin and the stomach of animals. The prepared stomach leather could be used in making of fancy leather goods like key ring, wrist watch belt, hair clip, bracelet etc.

Background: Cholelithiasis is a common problem these days. Earlier it was considered the health problem of the female only. But now it is quite common in the males also. The prevalence of gallbladder stone disease (GBSD) in female to male is 3:1 in 18-65 years age group. In the developed countries GBSD is common and occur in 7% in male and 15% in female with an overall prevalence of 11%. Cholecystectomy is one of the most common operation carried out in general surgery.Methods: Our study was conducted on 60 patients divided in 2 groups of 30 each to compare post-operative complications between laparoscopic cholecystectomy and open cholecystectomy.Results: As per findings of the present study duration of pain, rate of complications and total hospital stay were significantly lower in laparoscopic group. There was early removal of drainage tube, early stitch removal in laparoscopic group.Conclusions: Laparoscopic cholecystectomy can be recommended as first choice operative treatment for patients with cholelithiasis as it provides better cosmetic results, lesser pain, early removal of drainage tube, lesser post-operative hospital stay and fewer incidence of surgical site infection. It should be an available option for all patients requiring elective cholecystectomy.

Aim. To assess the surgical treatment outcomes for benign prostatic hyperplasia. Methods. The surgical treatment outcomes for benign prostatic hyperplasia were analyzed in 72 patients. 44 patients underwent transvesical prostatectomy ended with blind urinary bladder stitch, 28 patients with a prostate volume of less than 60 ml were offered transurethral resection of prostate. The patients’ mean age was 73.6 years. Inclusion criteria were: average urination flow rate (Qav) 10 ml/sec, total international prostate symptom score (I-PSS) 19, residual urine volume 50 ml. Prostate volume ranged from 29 to 150 ml. All interventions were performed using regional anesthesia. The effect of surgical treatment was assessed 3 months after the surgery was performed. Results. Self urination was restored at 2-3rd day. All patients had no residual urine. Urine flow parameters in patients after transvesical prostatectomy were: maximum urination flow rate (Qmax) - 24±1.3 ml/sec, Qav - 11.6±1.1 ml/sec; in patients after transurethral resection of prostate: Qmax - 17.2±0.8 ml/sec, Qav - 11.4±1.2 ml/sec. I-PSS index in the transvesical prostatectomy group was 2.3±0.3 compared to 9.7±1.1 points in transurethral resection of prostate group. Irritative symptoms prevailed in patients from transurethral resection of prostate group, 23 (82%) of them have improved after 1 month treatment with α1-adrenoblockers. Conclusion. Transvesical prostatectomy ended with blind urinary bladder stitch is still a radical and effective option for benign prostatic hyperplasia surgical treatment. Transurethral resection of prostate is effective in patients with prostate volume less than 60 ml and requires additional medical correction of irritative symptoms during the postoperative period.

The Precision Micro-Assembly Machine was developed to manufacture the ICF targets, which have submillimeter-sized components with micrometer sized features. The machine provides simultaneous manipulation of three objects in a 3-cm3 operating arena and can stitch together multiple millimeter-scales operating arenas over distances spanning tens of centimeters with micrometer-level accuracy. In this report, we will discuss the technologies that are merged to help assist the research community with micro-component fabrication. Furthermore, we also present the design of the online monitoring system, which contains two kinds of non-contact measurement system, microscopic image and laser confocal. The online monitoring system can characterize the positions of the target components during the assembly process. The effect and mathematic model of on-line measuring was analyzed. The results of target assembly experiments show position tolerance of the assembly is not more than 10μm.

Purpose The purpose of this paper is to establish the regression equation based upon a set of samples prepared through structured design of experiment and form a prediction model for prediction of the areal density gram per square meter (GSM) of the embroidered fabrics and study the influence of basic input parameters. Design/methodology/approach Embroidery samples are prepared taking input parameters as GSM of the base fabric, linear density of the embroidery thread and stitch density of the embroidery design. Three levels of values are identified for each of the input parameters. Taguchi and Box-Behnken experiment design principles are used to prepare two sets of samples. Linear multiple regression is used to determine the prediction equations based upon each of the two sets and the combined set as well. Prediction equations are statistically verified for the prediction accuracy. Also, surface curves are prepared to study the influence of embroidery parameters on the GSM. Findings It is found that all the three prediction models developed in this study can predict with a very satisfactory level of accuracy. However, the regression equation based upon the data set prepared according to Taguchi experiment design is emerged as the prediction model with highest level of prediction accuracy. Corresponding equation coefficients and several three-dimensional surface curves are used to study the influence of embroidery parameters and it is found that the stitch density is the most influential input parameter followed by stitch length and the GSM of base fabric. Research limitations/implications This can be used to assess the GSM of embroidered fabrics before starting the actual embroidery process. So, this model can help the embroidery designers significantly to pre-estimate the GSM of the embroidered fabrics and select the design parameters accordingly. Also, this model can be a useful tool for estimation of thread consumption and thread cost in embroidery. Practical implications The input parameters used here are very basic parameters related to design and materials, which can be easily available. And also, a simple linear multiple regression is used to make the prediction equation simple and easy to use. So, this model can help the embroidery designers or garment designers to select/adjust the embroidery parameters and thread parameters accordingly in the planning and designing stage itself to ensure that the GSM of embroidered fabrics remains within desirable range. Also, this prediction model developed hereby may be a very useful tool for estimation of the consumption and cost of embroidery threads. Originality/value This paper presents a very fundamental study to reveal the effect of embroidery parameters on the GSM, through development of regression equations. It can help future researchers in optimizations of input parameters and forming a technical guideline for the embroidery designers for selection of the design parameters for a desired GSM of embroidered fabric.

Full textAbstract:
One hundred and thirty patients with 339 divided flexor tendons affecting 208 fingers were studied prospectively between 1988 and 1996, to assess a regime of primary flexor tendon suture and active postoperative motion, combined with a modified Kleinert dynamic traction splint. The tendon suture technique used was a high-strength multistrand technique using a modified Kessler core and a Halsted peripheral stitch. The results were influenced by the zone in which the tendon was divided, by the physiotherapy and to a lesser extent by the grade of surgeon operating. Overall results by Strickland criteria were 92% excellent or good, 7% fair and 1% poor. There were 43 complications in 31 patients including five zone 2 ruptures (5.7%) and one further rupture in zone 5. This method of flexor tendon repair requires good physiotherapy and splint-making capability but gives good results with minimal need for further surgery.

Full textAbstract:
The theory of a secret revolutionary tradition, closely woven into the fabric of early working-class activity and surfacing at particular moments of crisis, continues to fascinate historians. In their attempts to assess its validity much recent effort has been directed at the ten years following the introduction of the infamous Two Acts in December 1795. There has been intensive study of the secret societies in the metropolis and their counterparts in the West Riding of Yorkshire and of their relationship to the Irish rebels. Yet whilst it si now generally recognised that radicalism did not simply evaporate in the oppressive aftermath of the “gagging acts”, its nature and significance continue to provoke disagreement. This paper is a contribution to this debate and an attempt to help stitch together a convincing account of plebeian protest in a region which, despite its prominent position in the radical history of this period, has received little systematic attention.

Background: Ventricular assist devices (VADs) are a relatively new development in the management of advanced heart failure. In the UK, VAD recipients comprise a unique group of less than 200 patients. This is the first paper to explore the experience of VAD communities, the extent to which communities are developed around the device, and how these influence the experience of living with the VAD. Methods: Qualitative interviews were conducted with 20 VAD recipients (implanted as a bridge to transplantation), 11 interviews also included the VAD recipients’ partners. Interpretive phenomenology was employed as the theoretical basis guiding the analysis of the interviews. Results: Four key themes emerged from the data: the existence of VAD communities; experiential knowledge and understanding; social comparisons; and the impacts of deaths within the VAD community. Many of the interviewees valued the VAD communities and the relationships they had formed with fellow recipients. The beneficial impacts of the VAD communities included offering recently implanted patients a realistic view of what to expect from life with a VAD; this could aid them in accepting and adapting to the changes imparted by the device. However, negative impacts of the VAD communities were also reported, in particular following deaths within the group, which were a source of distress for many of the interviewees. Conclusions: In general, the VAD communities appeared to be a beneficial source of support for the majority of interviewees. Consideration should be given to how these communities could be supported by clinicians.

Full textAbstract:
Friction stir welded (FSW) 304 austenitic stainless steel (SS) joints are studied using a range of microstructural characterization techniques to identify various sub-regions across the weld. A high-resolution (HR) 2D-digital image correlation (DIC) methodology is developed to assess the local strain response across the weld surface and cross-section in the elastic regime. The HR-DIC methodology includes the stitching of multiple images, as it is only possible to partially cover the FSW region using a single camera with the high-resolution optical set-up. An image processing procedure is described to stitch the strain maps as well as strain data sets that allow full-field strain to be visualized and interrogated over the entire FSW region. It is demonstrated that the strains derived from the DIC can be associated with the local weld geometry and the material microstructure in the region of the FSW. The procedure is validated in the material elastic range and provides an important first step in enabling detailed mechanical assessments of the local effects in the FSW process.

ObjectiveIn patients with non-ischaemic cardiomyopathy and reduced left ventricular ejection fraction (LVEF), normalisation of LVEF is associated with improved outcomes. However, data on patients with ischaemic cardiomyopathy and recovered LVEF are lacking. The goal of this study was to assess the prognostic significance of normalisation of the LVEF in patients with ischaemic cardiomyopathy.Methods/ResultsWe performed a non-prespecified post hoc analysis of the Surgical Treatment for Ischaemic Heart Failure (STICH) trial to determine the association between normalisation of LVEF (>50%) and mortality during follow-up. Of the 1212 patients with LVEF <35% enroled in the STICH trial, 932 underwent assessment of LVEF at 4 months and/or 2 years after enrolment. Among them, 18 patients experienced normalisation in LVEF at 4-month follow-up and 35 patients experienced recovery in LVEF at 2 years. Recovery of LVEF at 4 months and recovery of LVEF at 2 years were not correlated. Recovery of LVEF at 4 months was not associated with reduced all-cause mortality in unadjusted analysis (log-rank test p=0.54) or in Cox proportional hazards analysis (HR: 0.93; 95% CI: 0.48 to 1.80; p=0.82). Ejection fraction recovery at 2 years was associated with a reduction in all-cause mortality, both in unadjusted analysis (log-rank test p=0.004) and in the Cox proportional hazard model (HR: 0.41; 95% CI: 0.21 to 0.80; p=0.009).ConclusionsIn patients with ischaemic cardiomyopathy, delayed normalisation of LVEF is associated with reduced mortality, whereas early recovery of LVEF is not. Further studies are needed to confirm these findings.

CPH34 HV, a high volume stapler, was tested in order to assess its safety and efficacy in reducing residual/recurrent haemorrhoids. The clinical charts of 430 patients with third- to fourth-degree haemorrhoids undergoing SH in 2012-2013 were consecutively reviewed, excluding those with obstructed defecation (rectocele >2 cm; Wexner’s score >15). Follow-up was scheduled at six and 12 months. Rectal prolapse exceeding more than half of CAD was reported in 341 patients (79.3%); one technical failure was reported (0.2%) without any serious untoward effect; and 1.3 stitch/patient (SD, 1.7) was required to achieve complete haemostasis. Doughnuts volume was higher (13.8 mL; SD, 1.5) in patients with a large rectal prolapse than with smaller one (8.9 mL; SD, 0.7) (Pvalue <0.05). Residual and recurrent haemorrhoids occurred in 8 of 430 patients (1.8%) and 5 of 254 patients (1.9%), respectively. A high index of patient satisfaction (visual analogue scale = 8.9; SD, 0.9) coupled with a persistent reduction of constipation scores (CSS = 5.0, SD, 2.2) was observed. The wider prolapse resection well correlated with a clear-cut reduction of haemorrhoidal relapse, a high index of patient satisfaction, and clinically relevant reduction of constipations scores coupled with satisfactory haemostatic properties of CPH34 HV.

Introduction: Overweight and obesity during pregnancy is associated with increased risk for cesarean delivery. BMI is the most frequently used parameters to define and to assess risk of pregnancy related complications. Maternal abdominal subcutaneous fat thickness (SCFT) can be used as a measure of obesity. The present study was done to find association of maternal SCFT with risk of cesarean section. Methods: 200 women with singleton live pregnancy at 16-18 weeks were included in the study after obtaining written informed consent. Ultrasonography was done to assess foetal wellbeing and rule out congenital malformation. Maternal abdominal subcutaneous thickness was measured. All women were followed during labour till discharge. ROC curve analysis was done to predict the risk of cesarean section. Odd ratio for SCFT mediated risk of cesarean section was calculated. Results: 32.5% women had cesarean delivery. Mean SCFT was also significantly more in women delivered by cesarean than who delivered vaginally (p <0.001). ROC curve analysis for SCFT showed that SCFT above 11.5 mm (AUC=0.735) predicted LSCS with a sensitivity of 86.2% and specificity of 47.4% and Youden index of 0.34. Increased abdominal SCFT was significantly associated with increased risk of LSCS. . Using 11.5 mm cut -off value (by ROC curve) for SCFT, the odd ratio of LSCS was 7.5 (95% CI 3.4056 – 16.5837, p <0.0001). Stitch line infection was seen in 15.38% women. Conclusion: This study observed that measurement of SCFT by ultrasonography at 16-18 weeks pregnancy is a significant predictor of cesarean section.

The network pharmacology (NP) approach is a valuable novel methodology for understanding the complex pharmacological mechanisms of medicinal herbs. In addition, various in silico analysis techniques combined with the NP can improve the understanding of various issues used in natural product research. This study assessed the therapeutic effects of Arum ternata (AT), Poria cocos (PC), and Zingiber officinale (ZO) on hyperlipidemia after network pharmacologic analysis. A protein–protein interaction (PPI) network of forty-one key targets was analyzed to discover core functional clusters of the herbal compounds. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and gene ontology (GO) term enrichment analysis identified significant categories of hypolipidemic mechanisms. The STITCH database indicated a high connection with several statin drugs, deduced by the similarity in targets. AT, PC, and ZO regulated the genes related to the energy metabolism and lipogenesis in HepG2 cells loaded with free fatty acids (FFAs). Furthermore, the mixture of three herbs had a combinational effect. The herbal combination exerted superior efficacy compared to a single herb, particularly in regulating acetyl-CoA carboxylase (ACC) and carnitine palmitoyltransferase 1 (CPT-1). In conclusion, the network pharmacologic approach was used to assess potential targets of the herbal combination for treatment. Experimental data from FFA-induced HepG2 cells suggested that the combination of AT, PC, and ZO might attenuate hyperlipidemia and its associated hepatic steatosis.

The study was conducted on 130 females aged 25-35 years old. The research results were divided into four body shape groups from the sample based on classification criteria for FFIT body shape, as measured by principal component analysis, factor cluster analysis, and ANOVA test on SPSS software. Group 1 has 51 people, group 2 has 24 people, group 3 has 51 people, and theb last has 4 people. In each of four groups, choose the one with the highest percentage by sample number to design the base pattern. The products are evaluated on the model to check if the bra is comfortable when people wear it. Besides that, products are simulated through 3D V-Stitcher software to check the fit through the display of different colors on the tension and pressure charts. These evaluation results are checked for reliability by Cronbach's Alpha coefficient. The results of this study provide a way to assess the fit of clothes in accordance with the current 4.0 trend.

The present researchers took multistation-based panoramic images and imported the processed images into a virtual tour platform to create webpages and a virtual reality environment. The integrated multimedia platform aims to assist students in a surveying practice course. A questionnaire survey was conducted to evaluate the platform’s usefulness to students, and its design was modified according to respondents’ feedback. Panoramic photos were taken using a full-frame digital single-lens reflex camera with an ultra-wide-angle zoom lens mounted on a panoramic instrument. The camera took photos at various angles, generating a visual field with horizontal and vertical viewing angles close to 360°. Multiple overlapping images were stitched to form a complete panoramic image for each capturing station. Image stitching entails extracting feature points to verify the correspondence between the same feature point in different images (i.e., tie points). By calculating the root mean square error of a stitched image, we determined the stitching quality and modified the tie point location when necessary. The root mean square errors of nearly all panoramas were lower than 5 pixels, meeting the recommended stitching standard. Additionally, 92% of the respondents (n = 62) considered the platform helpful for their surveying practice course. We also discussed and provided suggestions for the improvement of panoramic image quality, camera parameter settings, and panoramic image processing.

Reinforcement of movement is an important mechanism by which sensory feedback contributes to motor control for walking. We investigate how sensory signals from movement and load sensors interact in controlling the motor output of the stick insect femur–tibia (FT) joint. In stick insects, flexion signals from the femoral chordotonal organ (fCO) at the FT joint and load signals from the femoral campaniform sensilla (fCS) are known to individually reinforce stance-phase motor output of the FT joint by promoting flexor and inhibiting extensor motoneuron activity. We quantitatively compared the time course of inactivation in extensor tibiae motoneurons in response to selective stimulation of fCS and fCO. Stimulation of either sensor generates extensor activity in a qualitatively similar manner but with a significantly different time course and frequency of occurrence. Inactivation of extensor motoneurons arising from fCS stimulation was more reliable but more than threefold slower compared with the extensor inactivation in response to flexion signals from the fCO. In contrast, simultaneous stimulation of both sense organs produced inactivation in motoneurons with a time course typical for fCO stimulation alone, but with a frequency of occurrence characteristic for fCS stimulation. This increase in probability of occurrence was also accompanied by a delayed reactivation of the extensor motoneurons. Our results indicate for the first time that load signals from the leg affect the processing of movement-related feedback in controlling motor output.

AimThe aim of this study was to assess the local and systemic response to poly-lactic co-glycolic acid (PLGA) 50:50 membranes, developed as synthetic biodegradable alternatives to the use of human donor amniotic membrane in the treatment of limbal stem cell deficiency.MethodsPLGA membranes of 2 cm diameter and 50 µm thickness were placed on one eye of rabbits and secured in place using fibrin glue and a bandage contact lens, suturing the eye close with a single stitch. Control animals were treated identically, with the absence of the membranes. Plain and microfabricated electrospun membranes (containing micropockets which roughly emulate the native limbal niche) were examined over 29 days. All animals were subjected to a detailed gross and histopathological observation as well as a detailed examination of the eye.ResultsApplication of the membranes both with and without microfabricated pockets did not adversely affect animal welfare. There was complete degradation of the membranes by day 29. The membranes did not induce any significant local or systemic toxicity. Conjunctival congestion and corneal vascularisation were noted in a few control and PLGA-treated animals. Intraocular pressure was normal and the retinal status was unaltered. The ocular surface was clear and intact in all animals by the end of 29 days.ConclusionMembranes of 50:50 PLGA can be safely applied to rabbit corneas without inducing any local or systemic toxicity and these break down completely within 29 days.

Full textAbstract:
The creation of a functional angioaccess is the cornerstone in treatment of chronic hemodialysis patients. The aim of this article is to review the use of vascular probes as a simple and cheap tool that could help surgeons in preparation of vessels and with creation of an anastomosis. Autogenous arteriovenous fistula is the best angioaccess available but is hampered by its relatively high non-maturation rate. Guidelines recommend preoperative duplex ultrasonography (USG) and use of vessels with a diameter that is able to maintain sufficient flow and fistula maturation to avoid unsuccessful attempts. Despite recommendations, preoperative duplex USG is not performed in many centers. In such circumstances, the use of vascular probes could help surgeons to create a fistula with a high chance of successful maturation. Vessel probes and dilators could be used to assess vessel diameter and patency, the ability to dilate and resolve a spasm, to stop retrograde blood flow in the vein (to avoid the use of vascular clamps), to avoid torsion of vein, to open and check vessel lumen with each stitch (to avoid using the forceps and possible wall injury), for tightening of continuous suture over the probe (to avoid excessive tightening and possible anastomotic stenosis). To my knowledge, this is the first review article which summaries the experience of using vascular dilators in angioaccess surgery. This information can be very helpful especially when there is the lack of valid preoperative USG of the vessels.

Technologies are rapidly evolving, allowing people to live healthier and simpler lives. Sightless people are unable to carry out their everyday activities, such as walking down the street, visiting friends or relatives, or doing some other mundane tasks. As a result, the smart stick is a stick that can assist a person in walking safely without fear of colliding with another person or solid objects is proposed as a solution to this major issue. It is a development of the traditional blind stick as it acts as a companion for the blind when walking by sending audio alerts to the blind via a headphone connected to the phone with obstacles (water/walls/stairs / muddy ground) and also enables him to make a phone call to ask for help. EasyEdasoftware was used for designing and simulating electrical circuits, was used to model the electric circuit.This system functions similarly to a white cane in that it assists blind people in scanning their surroundings for obstacles or orientation marks. This system will be mounted on a white cane with an ultrasonic sensor, and a water sensor to detect changes in the environment. Ultrasonic sensors detect obstacles in front of it using ultrasonic wave reflection, water detection sensors detect whether there is a puddle.

The purpose. Using clinical observation, to study the feasibility of applying a coagulant and to assess its efficacy in the treatment of patients with post-burn erosion of the cornea.Material and methods. The treatment was carried out in the Department of Trauma and Reconstructive Surgery, the Helmholtz Moscow Research Institute of Eye Diseases, Russia. Based on clinical test results, the patient, was diagnosed with post-burn persistent erosion of the cornea with sub-total cornea conjunctivization and: limbal stem cell deficiency (LSCD) in the right eye. The keratoprotective therapy conducted for several months turned ineffective. In order to activate the cornea regeneration process, the erosion site was covered with autologous thrombofibrin clot that had been obtained from the stabilized blood. Following a two-stage centrifugation of patient's stabilized blood, the plasma with the platelets were collected into a round-bottomed test-tube; and the chloride calcium activator was added. The clot was formed in the thermostat at a temperature of 37 С. The patient was given a local anesthesia, and the thrombofibrin clot was placed on the cornea surface and covered with an amniotic membrane. The membrane was fixed with a circular stitch along the limbus of the cornea.Result. The patient was followed-up and showed positive changes over time in the form of a diminished erosion area at day 5 and a complete corneal epithelialization at day 14.Summary. Our methodaimed at enhancing the reparative and regenerative processes in the cornea, reducing swelling, accelerating epithelialization, expanding transparency, and improving the optic characteristics thanks to less intensive opacity formation showed a high efficacy.

Background. The metabolic syndrome increases the risk of different diseases such as type 2 diabetes. The prevalence of metabolic syndrome has rapidly grown and affected more than 230 million people worldwide. Viola odorata is a traditionally used plant for the treatment of diabetes; however, its mechanism to manage diabetes is still unknown. Purpose. This study was designed to systematically assess the mechanism of action of Viola odorata in diabetes. Methods. An extensive literature search was made to establish an ingredient-target database of Viola odorata. Of these, targets related to diabetes were identified and used to develop a protein-protein interaction network (PPIN) by utilizing the STITCH database. The obtained PPIN was assessed through Gene Ontology (GO) enrichment analysis based on ClueGO plugin. Results. According to the acquired data, there were about 143 chemical constituents present in Viola odorata having 119 protein targets. Of these, 31 targets were established to give the pharmacological effect against diabetes. The UniProt database was used for screening of 31 targets, out of which Homo sapiens contained 22 targets. Ultimately, 207 GO terms, grouped into 41 clusters, were found by gene analysis, and most of them were found to be linked with diabetes. According to findings, several proteins including TP53, BCL2, CDKN1A, 1L6, CCND1, CDKN2A, and RB1 have a significant role in the treatment of diabetes by Viola odorata. Conclusion. The possible activity of Viola odorata in the management of diabetes may be mediated by several molecular mechanisms, including the glutamine metabolic process, IRE1-mediated unfolded protein response, and pentose metabolic process.
