Abstract:
There are many ways to detect the abnormality of rubber mixing process regardless of the availability of indicator system of the abnormality. One way is to detect the problem after the result of rubber production tested by laboratory teams. Abnormality will be late to be anticipated because the result of the test will appear after 8 to 10 batch afterward. The abnormality in the mixing process will be detected if the results of the testing compound are out of the specification. The energy consumption will be measured for every batch by using the internal current sensor in the AC motor main drive. By reading the figure of measurement, energy consumption character will be identified and the specification standard of energy consumption can be defined. The process will follow the specification standard of energy consumption and abnormality condition will be corrected immediately.

Abstract:
SummaryOpen-mout h locking due to lateral impingement of the mandibular coronoid process, lateral to the zygomatic arch, is described in five dogs and one cat. In order to elucidate the underlying cause of this abnormality, radiographs of temporomandibular joints of forty dogs, as well as the case history of a human patient, are compared. Three possible aetiologies are given, namely, flattening of the zygomatic arch, aberrant architecture of the condylar aspects, or contracture of the pterygoid muscle. An effective surgical treatment to prevent recur-rence of coronoid impingement was achieved by ostectomy of the locking part of the coronoid process.Unilateral protrusion of the mandible is described as a veterinary and comparative abnormality in five dogs, a cat and a woman. For the impingement of the coronoid process lateral of the zygomatic arch causing open-mouth locking in the animals, three aetiologies and an effective ostectomy of the coronoid process are given.

Abstract:
The research was conducted to evaluate the effect of incubation time on viability, plasma membrane integrity, abnormality, and DNA integrity of sexed Pasundan’s bulls sperm. The sperm sexing used 5% and 10% concentrations of Bovine Serum Albumin (BSA). A completely randomized design with three treatments and six replications was used in this study. The data were analyzed using variance analysis followed by Duncan’s multiple distance test. Parameter evaluated were sperm longevity, plasma membrane integrity (PMI), abnormality, and DNA integrity of sexed Pasundan bulls sperm. Results showed that incubation time gave significant effect (P<0.05) on the longevity of sperm, but not on the PMI of Pasundan bulls sexed sperm. The incubation time of 45 minutes gave the highest value of longevity sperm on the upper layer (4.33 days) and the lower layer (4.17 days). Furthermore, the abnormality of sperm X in the upper layer was 4.00%-4.20% and the lower layer was 4.10%- 4.40%. Meanwhile, the DNA integrity of an upper layer was 98.16%-98.66%, and the lower layer was 97.83%-98.58%. It is concluded that 45 minutes of incubation time significantly affected the longevity of sperm, but not plasma membrane integrity, abnormality, and DNA integrity of Pasundan bulls sexed sperm.

Abstract:
Speech abnormality is one of the effects of schizophrenia. Schizophrenia is a mental disorder caused by the imbalance of neurotransmitter levels in the brain. The brain has the most crucial role in language process, this affects the content of the message to be conveyed. Therefore, this study aimed to analyze speech abnormality of schizophrenic’s main character in Middle School movie. This study observed the types of speech abnormality of Rafe as the main character in the Middle School film. There were two objectives in this research; first, to identify the speech abnormality found in the Rafe’s utterances in the movie; second, to identify how Rafe’s utterances hindered the process of conveying information. Based on the analysis of speech abnormality, the finding revealed that Rafe experienced all types of speech bnormality. Based on Liddle's theory, these types included poverty of speech, weakening of goal, looseness, peculiar logic, peculiar sentence, peculiar word, preservation of ideas, and distractibility. This classification was based on Liddle's theory (2002). The researcher also used Carter's (2019) theory about languages influenced by the brain. The article concludes with a few suggestions to help people understand more clearly the types of schizophrenic speech abnormality.

Abstract:
Aim. To find thresholds at which laypersons and dental professionals from Jordanian population perceive abnormalities in sagittal positioning of upper and lower jaws as a major determinant to facial profile esthetics. Materials and Methods. Using photo editing software, a baseline profile image of a young male was manipulated on a 2 mm incremental basis to move each of the upper and lower jaws backward and forward relative to true vertical line (TVL) at which four variables of maxillary and mandibular retrusion and protrusion were researched. A total of 120 participants divided equally into four groups of laypersons, general dental practitioners (GDPs), orthodontists, and oral and maxillofacial surgeons (OMFSs) rated the images using an analog scale of 100 mm long. The image that showed the first statistical difference compared to the baseline was considered as a threshold of abnormality. Results. Laypersons, GDPs, and OMFSs perceived the abnormality in the maxillary retrusion at −5 mm to TVL, while orthodontists defined that at −3 mm. All dental professionals perceived the abnormality in the maxillary protrusion at +1 mm to TVL while the layperson group at +3 mm. A threshold of −7 mm mandibular retrusion to TVL was abnormally perceived by all groups. All dental professionals realized the abnormality in the mandibular protrusion at 0 mm to TVL while the laypersons at +2 mm. Conclusion. These thresholds regarding profile esthetics may contribute to the process of establishing proper orthodontic treatment planning that suits the highest facial esthetic standards.

Abstract:
Object Osteogenesis imperfecta (OI), which usually results from mutations in type I collagen genes, causes bone fragility and deformities. The head is often abnormally shaped, and changes in skull base anatomy in the form of basilar impression and basilar invagination have been reported. The authors analyzed the skull base anatomy on standardized lateral cephalograms from 54 patients with OI (Types I, III, and IV) and 108 control volunteers. They were surprised to find that the previously used diagnostic measures for basilar abnormality in patients with OI were exceeded in 6.5 to 7.4% of the controls, and hence needed to be reevaluated. Methods The authors calculated the distance from the odontoid process to four reference lines, including a novel one, in the controls. The normal mean distances were exceeded by more than two standard deviations (SDs) in 28.3 to 35.2%, and by more than three SDs in 13.2 to 16.6% of the patients with OI. The latter figures reliably reflect the prevalence of basilar impression. As a sign of basilar invagination the odontoid process protruded into the foramen magnum or reached the foramen magnum level in 22.2% of the patients with OI, whereas none of the controls showed this feature. Platybasia (an anterior cranial base angle > 146°) was present in 11.1% of the patients but in none of the controls. Conclusions Platybasia, basilar impression, and basilar invagination were often coexpressed, but each was also present as an isolated abnormality. These three abnormalities and wormian bones were predominantly found in OI Types III and IV as well as in patients exhibiting dentinal abnormality.

Abstract:
Most of the pre-existing modeling approaches for Automatic machining line (AML) concentrate on the equipment failure, but ignore some factors greatly influencing the performance of AML in production process, like the tool life, quality abnormality etc. Considering the above complex factors, a GSPN-based modeling approach is proposed to model the AML based on the fundamental principle of generalized stochastic petri nets (GSPN), which contributes to quantitatively analyze the relations between those factors and productivity of AML. The proposed modeling approach is applied in the automatic gear hobbing and shaving line in a gearbox factory. Some factors including equipment failure, cutting tool and quality abnormality are simulated to analyze the affections on the productivity, and the results show the validity of the approach.

Abstract:
Abstract Despite modern approaches in molecular biology and genetics, we are still not able to identify the actual cause in more than 50% of all congenital defects. One-half of the unidentified cases is referred to as “multifactorial”. Detailed prenatal investigation of the fetus can discover the presence of congenital abnormality, which can worsen the process of postnatal adaptation. Retrospective analysis of newborns admitted to the Neonatal Department of Intensive Medicine (NDIM) in 2012-2016 with the aim to analyze how the process of postnatal adaptation can be changed by the presence of congenital abnormalities of lip and palate. During a five-year period, 13 newborns were admitted to NDIM (2 premature; 11 term newborns). Chromosomal abnormality was confirmed in one patient (Down syndrome) and in one patient suspicion of Patau syndrome was found. Twelve newborns had complete cheilognathopalatoschisis. Two premature newborns and two term newborns had perinatal asphyxia. In this group of patients, 33% had respiratory insufficiency without the presence of congenital heart abnormality, 66% had congenital heart abnormality with respiratory insufficiency, and 2 patients had feeding problems. Only one patient had a positive family history. The diagnosis of complete cheilognathopalatoschisis was confirmed prenatally only in 9 patients. We confirmed that clinical consequences of congenital abnormalities of lip and palate depend on the nature, localization and range of abnormalities, as well as on the genetic background and accompanying congenital abnormalities. Prenatal confirmation of the presence of congenital abnormalities has an important influence on the postnatal management of a patient.

Full text
Abstract:
A nonparametric pattern classification method is introduced for fault diagnosis of complex systems. This method represents the fault signatures by the columns of a multi-valued influence matrix (MVIM), and uses adaptation to cope with fault signature variability. In this method, the measurements are monitored on-line and flagged upon the detection of an abnormality. Fault diagnosis is performed by matching this vector of flagged measurements against the columns of the influence matrix. The MVIM method has the capability to assess the diagnosability of the system, and use that as the basis for sensor selection and optimization. It also uses diagnostic error feedback for adaptation, which enables it to estimate its diagnostic model based upon a small number of measurement-fault data.

Abstract:
ABSTRACTTransfusion-acquired hemoglobinopathy occurs when a carrier of hemoglobinopathy with no significant abnormalities donates blood, and the blood is transfused to a recipient. This process can lead to spurious results in the recipient without any clinical abnormality or infrequently can result in disastrous situations. The incidental finding of such posttransfusion related abnormal peaks in hemoglobin high-performance liquid chromatography (Hb HPLC) may cause diagnostic dilemmas and result in unnecessary laboratory testing. Here, we report two such cases of transfusion-acquired hemoglobinopathies, which were subsequently resolved by the abnormally low percentage of the Hb variants, transient nature of the peaks, and parental Hb HPLC.

This study deals with the construction of network system for the production site, for the purpose of networking the machine tools as a part of the whole system. The Tele-monitoring for transformation of monitored information was studied. From the point of view of monitoring, the recognition of abnormal is very important in reducing the burden of an operator or for long-time unmanned operations. We then propose a method for the detection of abnormal in cutting process by analyzing the cutting sounds using Fourier transform, filtering, correlation analysis and statistic treatment. For the checking of tool wearing progressing, an experiment was arranged for the recognition of the sounds from a worn tip in comparison with a new one. On the detection of tipping of the cutter, a new tip is used for a long-time cutting without tool exchanging. The change of worn width and related values were compared with the original standard. It was found that the detection of tipping is possible by continuously sampling the cutting sounds and monitoring their correlation.

Abstract The relationship between chromosomal abnormality and oncogene activation was investigated during leukemic progression in two patients with myelodysplastic syndrome (MDS). Both patients had partial or complete deletion of chromosome 5 in metaphase cells obtained throughout the progression to leukemia. Analysis with specific oligonucleotide probes revealed that bone marrow cells containing an activated N-ras oncogene proliferated in a dominant manner during the process of leukemic conversion in both patients. These observations suggest that the chromosomal abnormality may precede activation of the N-ras gene in these patients, and that both the chromosomal abnormality and the activated N-ras oncogene contribute to the development of leukemia.

Abstract:
The purpose of this research was to evaluate the post-thawing quality (sperm motility, mortality and abnormality) of frozen-thawed Simmental bull semen with the addition of vitamin E in the extender. The material used for research were semen from two selected Simmental bulls. Vitamin E as treatment in addition to the extender consisted of T0 (no addition of vitamin E), T1 (0,134 gram/100 ml extender), T2 (0,268 gram/100 ml extender) and T3 (0,402 gram/100 ml extender). Post-thawing evaluation conducted 24 hours after the freezing process and observed after the thawing process in 37°C water bath for 30 seconds. Parameters observed in this research were the post-thawing quality of frozen-thawed Simmental bull semen based on motility, mortality and abnormality percentage. Sperm motility evaluated using a microscope with 100x and 400x magnifying, sperm mortality observed using 400x magnifying and counted based on 0,2% eosin-negrosin staining, sperm abnormality observed using 400x magnifying and counted based on the number of morphologically abnormal sperm cells. Semen post-thawing motility was not significantly affected by vitamin E addition of T1, T2 and T3 (P<0,05). T1 and T2 were able to significantly lower the mortality percentage compared to T0 and T3 (P<0,05). T1 and T2 were also very significantly affecting the decreased of abnormality percentage compared to T0 and T3 (P<0,01). T1 generally gave the best result on the improvement of post-thawing motility and decreased the percentage of sperm mortality and abnormality.

Full text
Abstract:
In this paper, we propose a robust adaptive cubature Kalman filter (CKF) to deal with the problem of an inaccurately known system model and noise statistics. In order to overcome the kinematic model error, we introduce an adaptive factor to adjust the covariance matrix of state prediction, and process the influence introduced by dynamic disturbance error. Aiming at overcoming the abnormality error, we propose the robust estimation theory to adjust the CKF algorithm online. The proposed adaptive CKF can detect the degree of gross error and subsequently process it, so the influence produced by the abnormality error can be solved. The paper also studies a typical application system for the proposed method, which is the ultra-tightly coupled navigation system of a hypersonic vehicle. Highly dynamical scene experimental results show that the proposed method can effectively process errors aroused by the abnormality data and inaccurate model, and has better tracking performance than UKF and CKF tracking methods. Simultaneously, the proposed method is superior to the tracing method based on a single-modulating loop in the tracking performance. Thus, the stable and high-precision tracking for GPS satellite signals are preferably achieved and the applicability of the system is promoted under the circumstance of high dynamics and weak signals. The effectiveness of the proposed method is verified by a highly dynamical scene experiment.

On the fracture of welding test pieces under tensile test formed two evident characteristic zones, one of which was the initial zone looking like arc ribbons alternating with each other. More obvious texture structure formed in the welding heat affected zone, with the direction consistent with that of the fracture in the up arc zonal fracture region. The reason of the abnormality was that relatively significant texture structure formed in the welding heat affected zone, while its formation was related to the temperature field and stress during the process of welding.

Abstract:
Abstract Introduction/Objective Histiocytic necrotizing lymphadenitis, also known as Kikuchi-Fujimoto disease (KFD), is a rare and benign self-limiting process primarily affecting 20~35-year-old Asian women with spontaneous remission after weeks to months of illness. Although the involvement of T cell-mediated immune response, infections, and HLA class II gene have been proposed as possible etiologies, the detailed pathogenesis has not been elucidated. Very few literatures exhibited KFD displaying chromosomal abnormality such as t(2:16). Methods Here, we report a rare case of KFD with novel karyotype abnormalities in a 24-year-old African American male. It presented as painless cervical lymphadenopathy for one month without fever, night sweats, or weight loss. An excisional biopsy of the lymph node (LN) was performed. Results Tissue culture for bacteria and flow cytometry of the LN were negative. Histopathology revealed numerous pale circumscribed foci composed of lymphocytes, histiocytes, plasmacytoid dendritic cells, and abundant karyorrhectic debris in the background of coagulative necrosis. No neutrophils or hematoxylin bodies are seen. Immunohistochemical studies showed CD3+/CD4+ T lymphocytes, CD68+ histiocytes, and CD123+ plasmacytoid dendritic cells. Abnormal karyotype was observed as: 46, XY, del(6) (q?16q?22). Conclusion We present this case to demonstrate that 1. Although KFD is most prevalent in young Asian females, it may occur in both genders and other ethnical groups and perhaps represents an underdiagnosed process. 2. KFD can mimic a variety of diseases such as rheumatologic, infectious, and hematologic malignancies; a thorough workup including serology, culture, and flow cytometry is needed to exclude serious diseases such as systemic lupus erythematosus and malignancy to render an early diagnosis which may avoid unnecessary diagnostic and therapeutic interventions. 3. Cytogenic abnormalities, although observed in many malignancies, should not be used as a sole determinant of malignancy, and the interpretation needs to be in a relevant clinical and histopathological context in a multidisciplinary setting to avoid misdiagnosis and inappropriate treatment.

Abstract:
A microtia, or small or abnormally formed pinna, is an uncommon congenital abnormality of the external ear which can present as an isolated defect or as part of an underlying clinical syndrome. External ear reconstruction is a possibility, with either an autologous or non-autologous framework. The Nagata type of autologous reconstruction is a multistage process whereby costal cartilage, temporoparietal fascia, and a full thickness skin graft are used to form a new pinna. Here, we present the unique case of a young female born with mosaic trisomy 22, an extremely rare genetic condition, and a right-sided microtia. Between the first and second stages of her reconstruction, an anterior chest wall deformation was observed, coupled with unusual dystrophic calcifications over the cartilage near the ribs and sternum.

Abstract:
Antioxidants can inhibit the oxidation process by reacting with free radicals, which in turn, maintain the quality of spermatozoa. This study aims to determine the viability and the abnormality of “ayam kampung” (Gallus gallus) spermatozoa after being diluted in ringer lactate infused with “sarang semut” (Myrmecodia Sp) extract. RAL is the research method used, utilizing 4 different Gallus gallus as test subjects. The variables observed are the abnormality and the viability of the spermatozoa sample treated with different amounts of Myrmecodia Sp extract, P0: 0 ml, P1: 0.02 ml, P2: 0.03, and P3: 0.04 ml. The abnormality rate for each sample is as follows; P0: 14 ± 4.05%, P1: 13.5 ± 3.78%, P2: 3.5 ± 1.23% and P3: 12.83 ± 5.04 %. Using the variance analysis, the result showed that the addition of Myrmecodia Sp extract in ringer lactate solution had little to no effect on causing spermatozoa abnormalities. Furthermore, the viability of spermatozoa for each sample is; P0: 14 ± 4.05%, P1: 13 ± 3.78%, P2: 13 ± 1.22% and P3: 12 ± 5.04%. Based on the variance analysis, the result showed that Myrmecodia Sp extract had a significant effect (P <0.05) on the spermatozoa viability. The addition of Myrmecodia sp extract to ringer lactate diluter had little to no effect on the abnormality of the Gallus gallus’ spermatozoa but had a significant effect on the spermatozoa’s viability.

Abstract:
During the rotary machine operation process, seemingly small amounts of abnormal vibration can often cause serious damage to the machinery over time and even increase the risk of accidents. Although professional vibration engineers can determine the current health status of a machine by interpreting the vibration spectrum information and predicting which components will fail, if even ordinary operators can send feedback regarding the vibration signals reaching the human–machine interface through a system when an abnormality is detected in the machine, the abnormality can be made known and processed in time. This can prevent the magnified impact of rotary inertia, thereby lowering the risk of major damage and the failure of machinery and equipment, as well as effectively saving on equipment maintenance costs. This study mainly adopted LabVIEW and Arduino IDE to develop a control program and human–machine monitoring interface. As the initial experiment on rotary machine vibration monitoring and smart balance correction, the measurement system setup in this study was applied to determine vibration abnormality as well as to carry out continuous online automatic balance correction. Experimental verification was carried out using active correction and smart correction. In terms of active online balance correction, the amplitude correction rate was 96%, the double-frequency correction rate was 102.9%, and the correction process was performed in 5 min. In terms of smart balance correction, the amplitude correction rate was 103.8%, the double-frequency correction rate was 103.3%, and the correction process was performed in 3 min. Through feedback signaling, the operator can effectively learn the current health status of the mechanical equipment from the human–machine interface.

Fruit disease detection becomes critical since economic and related issues are influenced through the healthy and non-healthy fruits. Technology has advanced and is used to primarily detect and abnormality which is not visible through the naked eye. This paper proposes a new technique of fruit disease detection at early stage for which Gaussian smoothening is used at pre-processing stage along with weighted kernel function within SVM for achieving higher classification accuracy. Feature extraction and selection mechanism uses rank based mechanism that allocates ranks on the basis of predictive significance. The result is obtained in terms of prediction accuracy and mean or average error. Result is optimized by the factor of 10%.

Leaflet motion abnormalities are a relatively new entity in the field of transcatheter aortic valve implantation and are associated with a range of different conditions, the extreme being prosthetic valve dysfunction with high gradients or central regurgitation and possibly early thrombotic degeneration. Another extreme condition is the incidental finding of leaflet thickening, but with normal transvalvular gradients. Transthoracic echocardiography is a useful screening tool for the detection of symptomatic thrombosis, but it has limited use in the detection of subclinical thrombosis and/or motion abnormalities alone. We, hereby, discuss the evidence for the potential screening process and subsequent management of those conditions associated with the leaflet motion abnormalities.

Abstract:
Assistive health care system is a viable solution for elderly care to offer independent living. Such health care systems are feasible through smart homes, which are intended to enhance the living quality of the occupant. Activities of daily living (ADL) are considered in the design of a smart home and are extended to abnormality detection in the case of health care. Abnormality in occupant behavior is the deviation of ongoing activity with that of the built activity model. Generally, supervised machine learning strategies or knowledge engineering strategies are employed in the process of activity modeling. Supervised machine learning approaches incur overheads in annotating the dataset, while the knowledge modeling approaches incur overhead by being dependent on the domain expert for occupant specific knowledge. The proposed approach on the other hand, employs an unsupervised machine learning strategy to readily extract knowledge from unlabelled data using contextual pattern clustering and subsequently represents it as ontology activity model. Ontology offers enhanced activity recognition through its semantically clear representation and reasoning, it has restriction in handling temporal data. Hence, this article in addition to unsupervised modeling focuses at enabling temporal reasoning within ontology using fuzzy logic. The proposed fuzzy ontology activity recognition (FOAR) framework represents an activity model as a fuzzy temporal ontology. Fuzzy SWRL rules modeled within ontology aid activity recognition and abnormality detection for health care. The experimental results show that the proposed FOAR has better performance in abnormality detection than that of the existing systems.

Abstract:
In recent years in medical imaging technology, the advancement for medical diagnosis, the initial assessment of the ailment, and the abnormality have become challenging for radiologists. Magnetic resonance imaging is one such predominant technology used extensively for the initial evaluation of ailments. The primary goal is to mechanizean approach that can accurately assess the damaged region of the human brain throughan automated segmentation process that requires minimal training and can learn by itself from the previous experimental outcomes. It is computationally more efficient than other supervised learning strategies such as CNN deep learning models. As a result, the process of investigation and statistical analysis of the abnormality would be made much more comfortable and convenient. The proposed approach’s performance seems to be much better compared to its counterparts, with an accuracy of 77% with minimal training of the model. Furthermore, the performance of the proposed training model is evaluated through various performance evaluation metrics like sensitivity, specificity, the Jaccard Similarity Index, and the Matthews correlation coefficient, where the proposed model is productive with minimal training.

In order to monitor nonlinear production process effectively, multivariate statistical process control based on kernel principal component analysis is applied to process monitoring and diagnosis. Squared prediction error (SPE) statistic of the kernel principal component analysis (KPCA) model is used for process monitoring, and the fault causes of the production process could be tracked by the methods of data reconstruction and the optimal neighbor selection strategy. Simulation data and Tennessee Eastman process data are used for model validation, as a result the proposed method has better performance on abnormality detecting, compared with multivariate statistical process control based on linear principal component analysis. What is more, the causes of the faults are tracked effectively, thus the production process can be adjusted to prevent substandard products.

Mandibular accessory condyle is rare. Literature search found most of the accessory condyles to arise from the mandibular coronoid process due to hyperactivity of attached temporalis muscle. Although neoplastic growth at mandibular coronoid mimicking an accessory condyle also been cited. Absence of report in recent publications regarding accessory mandibular condyle arising from the main mandibular condyle makes this anomali extremely rare. The present case report is about a true accessory mandibular condyle which caused the patient facial and occlusal disharmony. A 3D computerized tomographic imaging ascertained the exact location of the accessory condyle, its origin and resting position of the accessory and the main condylar head. The facial and occlusal disharmony settled completely within a short postoperative time following surgical intervention and mild elastic traction.Delta Med Col J. Jan 2016 4(1): 45-50

Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH.

Abstract:
Modern biomedical psychiatry is the product not only of scientific enterprise but also of the progressive secularisation and medicalisation of moral life in the West (Jimenez, 1987). Psychiatry is an evolving cultural product. Its diagnostic categories represent pathologies rooted in Western notions of self, identity, normality and abnormality (Gaines, 1991). Psychiatric practice in Egypt, on the other hand, is the product of two different and often incompatible world views, namely Western psychiatry and Egyptian concepts of self, identity, normality and abnormality. The task of the psychiatrist in Egypt is to negotiate symptoms and diagnoses in a way that is sensitive to the demands of these two competing cultural streams. Analysis of this process provides a unique view of the ways in which culture can have an impact on professional psychiatry in any society or ethnic context.

Abstract:
AbstractBackground:Misinterpretation of medical images is an important source of diagnostic error. Errors can occur in different phases of the diagnostic process. Insight in the error types made by learners is crucial for training and giving effective feedback. Most diagnostic skill tests however penalize diagnostic mistakes without an eye for the diagnostic process and the type of error. A radiology test with stepwise reasoning questions was used to distinguish error types in the visual diagnostic process. We evaluated the additional value of a stepwise question-format, in comparison with only diagnostic questions in radiology tests.Methods:Medical students in a radiology elective (n=109) took a radiology test including 11–13 cases in stepwise question-format: marking an abnormality, describing the abnormality and giving a diagnosis. Errors were coded by two independent researchers as perception, analysis, diagnosis, or undefined. Erroneous cases were further evaluated for the presence of latent errors or partial knowledge. Inter-rater reliabilities and percentages of cases with latent errors and partial knowledge were calculated.Results:The stepwise question-format procedure applied to 1351 cases completed by 109 medical students revealed 828 errors. Mean inter-rater reliability of error type coding was Cohen’s κ=0.79. Six hundred and fifty errors (79%) could be coded as perception, analysis or diagnosis errors. The stepwise question-format revealed latent errors in 9% and partial knowledge in 18% of cases.Conclusions:A stepwise question-format can reliably distinguish error types in the visual diagnostic process, and reveals latent errors and partial knowledge.

Abstract:
Abstract Background: Waldenstrom’s Macroglobulinemia(WM) is a rare B-cell disorder characterized by the accumulation of monoclonal lymphoplasmocytic cells and a serum monoclonal IgM protein. The genetic basis of this disorder is poorly understood. Molecular cytogenetic abnormalities differ from those reported for multiple myeloma, lymphomas, and B-cell chronic lymphocytic leukemia. One recurrent abnormality, deletion of the long arm of chromosome 6, was reported with a high prevalence (23–50%), but seems associated with advanced disease and clonal evolutions. Aims : As data on molecular changes in WM are limited, we used interphase fluorescence in situ hydidization (IP-FISH) to evaluate the prevalence of trisomy 4 in WM patients. Material and methods: 39 patients with a diagnosis of WM , according to the Workshop classification, were included: 28 men and 11 women. Mean age at diagnosis was 66 years (48–84 years). Mean percentage of bone marrow lymphoplasmocytic cells was 47% (13–97%). Conventional cytogenetic was performed after 72 or 96 hours culture with TPA, at diagnosis for 23 patients and 3.8 years median (6 months–9 years) after for 13. FISH study was carried on cytogenetic cryopreserved pellets using a CEP-4 probe (Qbiogene, Illkirsch, France) Results: Karyotypes were available for 37cases (2 failures): 24 were normal, 3 had a trisomy 4, (2 as the sole abnormality), 2 a partial loss of 17p (one deletion and one additional material), 2 a loss of sexual chromosome, 1 a t(11;18), 1 a partial duplication of 17q, 1 a partial monosomy 5q with insertion of unknown material in 4q, 1 a complex karyotype with a partial trisomy 4 and 2 with abnormal independent clones. IP-FISH: The 3 complete trisomies 4, already seen by conventional cytogenetic, were confirmed and 4 others were detected. The mean percentage of cells with trisomy 4 was 31% (11–52%) (cut-off 2%, median+4SD) Discussion: We found that 7 of 39 patients (18%) with WM harboured a complete trisomy 4 with IP-FISH, contrary to only three (8%) with conventional cytogenetic. This study, performed in interphase, is independent of the proliferation rate. Therefore the prevalence is probably underestimated since IP-FISH was realized in unselected cells: in 11 patients the percentage of clonal involvement of the bone marrow was under 30% and it was unknown in 6 patients. The mean percentage of bone marrow lymphoplasmocytic cells was higher for patients with trisomy 4 (63%) than in others (43%). The trisomy 4 was the only abnormality in 2 of the 3 karyotypes where it was identified and in one sporadic case reported previously. Thus it could be a specific primary genetic event in the WM. Moreover, the detection of one partial trisomy 4 define an interesting region with potential oncogene. cKIT, located at 4q12, was a good candidat gene and molecular studies are in process. Conclusion: We identified a new recurrent chromosomal abnormality in WM, the trisomy 4, with a prevalence of at least 18%. The exact prevalence of this abnormality should be determined by IP-FISH study in CD19+ and CD138+ selected cells. This abnormality could be primary and could lead to elusive the molecular pathogenesis of WM.

Abstract:
As smart grids develop rapidly, low-cost monitoring systems for pole-mounted transformers increase in demand. Even though battery-powered wireless monitoring systems appear to provide optimal solutions, they consume large amounts of energy for continuous sampling and data transmission. Operation and maintenance costs then increase owing to reduced battery lifetime and battery replacement. To overcome this problem, this paper presents an event-driven battery-powered wireless monitoring system that monitors abnormalities of a transformer and transmits data only if an abnormality occurs. When the proposed event controller detects an abnormality, it enables a root mean square (RMS) converter and a peak detector for sampling and transmitting the maximum RMS value of the abnormal signal and then falls into sleep mode until the next event to save energy. Simulation and experimental results show that the proposed system enhances battery lifetime by up to two orders of magnitude compared to a conventional battery-powered wireless monitoring system.

Abstract:
Mammalian transient receptor potential (TRP) channels are major components of Ca2+ signaling pathways and control a diversity of physiological functions. Here, we report a specific role for TRPC1 in the entry of herpes simplex virus type 1 (HSV-1) into cells. HSV-1–induced Ca2+ release and entry were dependent on Orai1, STIM1, and TRPC1. Inhibition of Ca2+ entry or knockdown of these proteins attenuated viral entry and infection. HSV-1 glycoprotein D interacted with the third ectodomain of TRPC1, and this interaction facilitated viral entry. Knockout of TRPC1 attenuated HSV-1–induced ocular abnormality and morbidity in vivo in TRPC1−/− mice. There was a strong correlation between HSV-1 infection and plasma membrane localization of TRPC1 in epithelial cells within oral lesions in buccal biopsies from HSV-1–infected patients. Together, our findings demonstrate a critical role for TRPC1 in HSV-1 infection and suggest the channel as a potential target for anti-HSV therapy.

The kidney duplication is the most common abnormality of the urinary system. In most cases, this condition is an accidental finding on prenatal ultrasound or can be diagnosed when the first clinical manifestations occur. Abnormalities of the upper urinary tract can be detected when examining a patient with arterial hypertension, proteinuria, or renal failure. As an example of the complicated course of the inflammatory process in a patient with quantitative kidney abnormality, a clinical observation of the course of obstructive pyelonephritis against the background of complete obliteration of the lower third of the ureter with the formation of terminal changes in the upper half of the doubled kidney, which led to renovascular hypertension and clinically significant renal failure, is presented. The article describes the clinical manifestations of the disease, laboratory and diagnostic screening, as well as the stages of surgical treatment in a multidisciplinary hospital.

Abstract:
<p class="0abstract">Cardiovascular diseases (CVD) are the prime cause of mortality in people worldwide. Mortality in CVD has been strongly linked to Ejection Fraction (EF) in various studies<sup>1</sup>. Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at the end of diastole (end-diastolic volume)<sup>2</sup>. Evaluation of left ventricular systolic function by left ventricle ejection fraction (EF) using Transthoracic echocardiography is usually a first line investigation. Determination of Ejection fraction (EF) is done most commonly by a semi-automatic process in which echocardiographer segments the left ventricle in both systolic and diastolic frames to generate systolic and diastolic chamber dimensions. The whole process in time consuming and highly dependent on operator experience causing a lot of inter-observer and intra-observer variations. Our goal is to develop algorithms so as to reduce the time consumed during whole process and make it more reliable and reproducible. We have used M-Mode of Left ventricle in PLAX view to measure chamber dimensions and calculate EF by Teich method. EF >50% has been categorized as normal ejection fraction. EF < 50% has been categorized as reduced ejection fraction and LV systolic dysfunction. In this research we have used fine-tuned ResNet 50 and trained it with 200 cases. We observed an accuracy of 98% and a F1 score of 77% for reduced EF (<50%) and 77% for normal EF (>50%). Although this is a small dataset, it shows that deep learning algorithms can be applied to medical imaging. ResNet50 is a preferred choice in terms of accuracy. This research will serve as a stepping stone for future research and will determine other cardiac matrices.</p>

Abstract:
The lungs are one of the important and vital organs in the body that function as a respiratory system process. One way to detect lung disease is to do an X-rays test. Chest X-ray is a radiographic projection to detect abnormalities in lung organ by using x-ray radiation. In the process of diagnosing, doctors see the condition of the results of Chest X-rays in the form of a thorax image (chest) to know the patient has an abnormal or normal lung. However, doctors' diagnosis of chest X-rays results-based abnormalities is likely to differ depending on the doctor's abilities and experience. This problem is expected to be solved by segmenting the lung image to help make the diagnosis appropriately. The purpose of this study is to conduct an analysis that can differentiate abnormal and normal lungs. The process of recognition of these patterns consists of the pre-processing stage of image segmentation by using morphology and then proceed to grouping by using fuzzy c-means method to express the pattern of the already segmented image. This research produces normal and abnormal lung images that can be identified with an accuracy of 80%.
