Full textAbstract:
Herein, we report the catalytic activity of nebivolol nanoparticles a novel organocatalyst for the synthesis of DHPMs and DHPM-5-carboxamides. The nanoparticles are confirmed by DSC, TEM, AFM, and IR spectroscopy. The catalyst can be readily recovered and reused for the next four runs without any significant impact on the yields of the products. The products are fully characterized by FTIR, 1H NMR, 13C NMR, and distortionless enhanced polarization transfer (DEPT) NMR. The methodology adopted here offers several advantages such as solvent-free reaction, low loading of catalyst, short reaction times, and quantifiable yields.

Garlic (Allium sativum L.) has been cultivated by asexual propagation since time immemorial. The discovery of male-fertile garlic accessions has opened a venue for genetic studies and improvement through sexual recombination. An S1 family of 84 plants was generated from a single male-fertile heterozygous plant from the U.S. Dept. of Agriculture Plant Introduction 540316 and used to identify the first genetic linkages in garlic based on single nucleotide polymorphisms, simple sequence repeats, and randomly amplified polymorphic DNAs. Thirty-seven markers formed nine linkage groups covering 415 centimorgans (cM) with average distance of 15 cM between loci; other 16 loci remained unlinked. A male fertility locus was placed on the map. This first genetic map of garlic is a seminal step toward the genetic improvement of garlic and eventual marker-assisted breeding.

Integral balance solution employing entire domain approximation and the penetration dept concept to the Stokes? first problem of a viscoelastic generalized second grade fluid has been developed. The solution has been performed by a parabolic profile with an unspecified exponent allowing optimization through minimization of the norm over the domain of the penetration depth. The closed form solution explicitly defines two dimensionless similarity variables and , responsible for the viscous and the elastic responses of the fluid to the step jump at the boundary. The solution was developed with three forms of the governing equation through its two dimensional forms (the main solution and example 1) and the dimensionless version showing various sides of the flow field and how the dimensionless groups control it: mainly the effect of the Deborah number. Numerical simulations demonstrating the effect of the various operating parameter and fluid properties on the developed flow filed have been performed.

Full textAbstract:
6046 Background: HAIs are dangerous complications of HNC treatment. In lack of data we collected own data in a high volume HNCMOU, comparing them with those observed in other departments. Methods: HAIs recorded retrospectively among 2,288 hospital admissions at our HNCMOU observed from 2005 to 2009 were compared with 427 recent (2010-2012) hospital admissions. In the same period HAIs observed in ENT Surgical, Medical Oncology (MO) and Bone Marrow Transplantation (BMT) dept were recorded. Results: Between 2005 and 2009, 140 HAIs were observed in the HNCMOU: 49% Gram-, 35% Gram+, 16% fungi; 88% of P. Aeruginosa and all Enterobacteriaceae were sensible to meropenem and piperacillin/tazobactam, methicillin-resistant S. aurei (MRSA) were 42% (Table). In the last 3 years infections and resistances rates increased with a similar pattern of bacteria: among 212 HAIs (43% Gram-, 32% Gram+, 24% fungi) the majority (39%) involved respiratory tract, 89% of P. aeruginosa and 92% of Enterobacteriacae were sensible to carbapenem and 89% and 51% were sensible to piperacillin/tazobactam. MRSA were 29%. We compared these data with HAIs occurred from 2005 to 2012 into other dept: most of HAIs in ENT Surgical dept were at surgical site (41%) due to Gram+ (45%), in BMT were sepsis (56%) due to Gram+ (51%) and in MO were urinary tract infections (39%) due to Gram – (70%). Conclusions: Gram- continue to represent the first cause of HAIs in HNC cancer patients treated with CT and/or RT, suggesting a peculiar pattern. This is paralleled by a rise in carbapenem resistance, while MRSA still represent a significant fraction. [Table: see text]

Petunia × hybrida Wave series cultivars were observed with symptoms of tan to brown stem lesions, wilt, and branch death in a demonstration/trial planting at Burden Research Center in Baton Rouge, LA, during January and February 2000. Disease signs included the presence of white, cottony mycelia on infected stems and the presence of black sclerotia. Seventeen of 131 plants were infected on 20 February and included individuals of cvs. Wave Purple, Wave Rose, Wave Misty Lilac, Wave Pink, Tidal Wave Hot Pink, and Tidal Wave Cherry. Isolations were made by placing diseased stem sections on acidified potato-dextrose agar. A fungus that produced white mycelia and black sclerotia was consistently isolated from infected stems and identified as Sclerotinia sclerotiorum. Pathogenicity tests were done by pipetting 1 to 2 ml of blended mycelia and sclerotia (one plate culture blended in 100 ml distilled water) at the base of flowering-age Wave series plants. Plants were held for 3 days in a dew chamber maintained at 22°C and then moved to a greenhouse held at 25°C. Wilt and branch death developed on inoculated plants after 5 days and S. sclerotiorum was reisolated. Uninoculated plants remained healthy. Wave series cultivars have a prostrate growth habit that is conducive to disease development. No plants in the trial planting were killed and infected plants had recovered by 1 May and had uniformly covered the plant bed. Sclerotinia blight was previously reported on Petunia × hybrida from Bermuda (2) and Florida (1). References: (1) D. F. Farr et al. 1989. Fungi on Plants and Plant Products in the United States.

Abstract Introduction: Several cooperative MM groups have shown that MRD monitoring may be relevant as biomarker to evaluate the efficacy of different treatment strategies, to support treatment decisions, and to act as surrogate for overall survival (OS) in MM. Because of its wider applicability, a significant fraction of available MRD data has been obtained using MFC that originally, was limited to 4- or 6-colors and measured a limited number of cells. It is assumed that the sensitivity of MFC can increase by usage of ≥8 markers and acquisition of greater cell numbers, but the degree of improved specificity and sensitivity remains unknown. Methods: We aimed at determining the increment in specificity and sensitivity upon transition from first-generation 4-color into a second-generation 8-color MFC assay, by applying new computational tools developed by the EuroFlow consortium in elderly MM patients, enrolled in the GEM2010MAS65 study, for which MRD monitoring was performed with an 8-color monoclonal antibody combination - CD45-PacB/CD138-OC515/CD38-FITC/CD56-PE/CD27-PerCPCy5.5/CD19-PECy7/CD117-APC/CD81-APCH7 - and acquisition of ≥2x106 leukocytes (detection limit: 10-5). Time-to-progression (TTP) and OS were measured from diagnosis. Results: First, we created a reference data file of normal (n=17) and clonal (n=71) plasma cells (PCs) derived from bone marrow samples of healthy individuals and MM patients (Figure 1A) in order to determine the individual contribution of each marker to the discrimination between normal vs. clonal PCs. Principal component analysis (PCA) showed that CD19 ranked as the most significant marker followed by CD56, CD81, CD27, CD117, CD45, forward scatter (FSC), CD38, CD138 and sideward scatter (SSC). Accordingly, the 8-color combination resulted in improved discrimination between normal vs. clonal PCs as compared to the former 4-color approach based only on CD38/CD56/CD19/CD45 (Figure 1B); in fact, CD81, CD27 and CD117 had higher independent value than CD45 in the PCA. Afterwards, we focused on 50 randomly selected MRD-positive patients enrolled in the GEM2010MAS65 study, to compare the performance of an 8- vs. 4-color software-guided classification of MRD cells. PCA based on 8-colors showed that all but two patients were accurately located in the clonal PC reference and outside 1 or 2 standard deviation (SD) curves of the normal PC reference (96% accuracy; Figure 1C); by contrast, using 4-color software-guided classification up to 9 patients became located in the overlapping area between 1 and 2 SD of the normal and clonal PCs references (82% accuracy; Figure 1D). Afterward, we investigated the increment in sensitivity due to the evaluation of 2x106 leukocytes with the second-generation 8-color flow assay instead of the standard 2x105 cells with the first-generation 4-color approach, by determining how many of the 50 MRD-positive patients would turn into MRD-negative if only 2x105 leukocytes had been analyzed (detection limit: 10-4). Interestingly, by reducing the number of visible events to 2x105, our results showed that up to 15 out of the 50 cases (30%) would become wrongly classified as MRD-negative. Then, we investigated the impact in TTP and OS of having MRD levels of 10-5 within a series of 163 patients enrolled in the GEM2010MAS65 and with MRD assessment. Accordingly, 88 cases had detectable MRD levels ≥10-4, 21 patients had persistent MRD at 10-5, and the remaining 54 cases were MRD-negative. Importantly, MRD-positive patients at 10-5 had similar outcome as compared to cases with MRD levels ≥10-4 (both had median TTP of 31 months; 3-year OS rates were 80% and 74%, respectively) and significantly inferior to that of MRD-negative patients [median TTP not reached (P <.001); 3-year OS rate of 93% (P =.05)]. Conclusions: We showed that the transition from a first-generation 4-color into a second-generation 8-color MFC assay that measured ten-times more cells resulted in increased specificity and sensitivity. MRD detection at the 10-5 level is clinically relevant, since it identifies a subset of patients with inferior survival than MRD-negative cases, similar to that of the overall MRD-positive patient population.

Diseases of dandelion (Taraxacum officinale) were surveyed in southern Ontario from 1993 to 1997 to identify promising pathogens for biological weed control. Two new pathogens of dandelion, Phoma herbarum Westend. and Phoma exigua Desm., were recovered and characterized from small necrotic lesions on dandelion foliage. Both Phoma spp. were frequently isolated from multiple locations and during various years of the survey, indicating that they were endemic and widespread on T. officinale in southern Ontario. Pathogenicity was assessed by inoculating detached leaves or seedlings with colonized agar disks (6 mm in diameter) or spore suspensions (1 × 106 conidia per ml). Inoculated leaves and seedlings were incubated at 22°C and 48 h of continuous leaf wetness. Lesion diameters were measured 3 days post-inoculation. Isolates that gave rise to necrotic lesions were reisolated from leaves and grown in pure culture. Their growth characteristics were compared with those of the initial isolate. Spores were ellipsoid, hyaline, and 5 × 2 μm for both species. Identification of representative isolates of both species was confirmed by the Centraalbureau voor Schimmelcultures, Oosterstraat 1, 3742 SK Baarn, The Netherlands. This is the first report of these two species as pathogens of dandelion in North America (1,2). References: (1) I. L. Conners 1967. An Annotated Index of Plant Diseases in Canada.

3061 Background: We have studied our recent experience in the MDACC Clinical Translational Research Center (CTRC), the Phase I Program, and the Dept. of Thoracic/Head & Neck Medical Oncology to compare the extent of regulatory and other requirements for current phase I and II cancer clinical trials. Methods: We developed a comprehensive database, together with a Microsoft Excel spreadsheet matrix to analyze the number and extent of diagnostic and therapeutic requirements for each protocol. We then examined the demands for pharmacokinetic (PK) sampling as well as electrocardiography (ECG) in the first cycle of a protocol as a surrogate for study complexity. Results: Since October, 2002, 250 protocols have been conducted in the CTRC; 54.6% were Phase I clinical trials. We reviewed 65 trials, approximately one quarter of the total. Of these, 48 were phase I trials carried out by the Phase I Program. For comparison, we identified 17 phase II trials managed by the Dept. of Thoracic/Head & Neck Medical Oncology during the same time period. In the phase I trials there were significantly more PKs (mean ± SE = 16.69 ± 1.93) than in the phase II trials (mean ± SE = 1.82 ± 1.17) (p<0.0001). Similarly, there were more ECGs in the phase I versus phase II trials (4.46 ± 1.18 vs. 1.41 ± 0.35; p=0.017). Conclusions: Pharmacokinetic collection and ECG monitoring in Phase I trials are complex and labor-intensive. In addition, they represent only a small portion of time-intensive requirements, with increasingly complicated correlates and monitoring (physical exams, imaging, etc.). Successful and accurate Phase I clinical trials require resources and commitment for research infrastructure considerably greater than later phase studies.

Full textAbstract:
Background: The clinical presentation of chest pain is a major problem for primary health care professionals. Rapid access chest pain clinics (RACPC) enable quick assessment, investigation and formation of a treatment plan for such patients without a waiting list. There has been a chest pain clinic in operation at Harefield Hospital since 1988. Until 2001, the cardiology registrars were responsible for the clinic. Beginning in January 2001, the management of the clinic was taken over by the Cardiology Nurse Consultant. This paper will describe the organisation and outcomes of the first 3 years of this nurse-run RACPC. Process: Patients are seen within 2 weeks of referral in line with the National Service Framework for Coronary Heart Disease [Department of Health. National service framework for coronary heart disease. Dept of Health; 2000. London.]. An electrocardiogram (ECG) is recorded on arrival in the clinic and the Nurse Consultant then examines the patients and decides if further investigation is required. Analysis of Results: Four hundred and fifty-four patients were seen in the clinic from January 2001–December 2003. Three hundred and twenty-four patients (71.4%) underwent exercise testing of which 54 (16.7%) had a positive result. One hundred and thirteen patients (24.9%) were referred for angiography. Of these, 75 (66.4%) had coronary heart disease. Thirty-three patients (29.2%) have undergone percutaneous coronary intervention (PCI) and 19 (16.8%) have required coronary artery bypass grafting (CABG). Twenty-three patients (20.4%) are being treated medically. Satisfaction with the service offered by the clinic was high, evidenced by the results of questionnaires sent to patients. Conclusion: This paper demonstrates that nurses can successfully run RACPCs without an increased risk of incorrect diagnosis. These clinics offer patients timely access to assessment of their chest pain and facilitate early diagnosis of cardiac disease. They are also well accepted by the patients attending the clinic.

Glucosylation of the 21-hydroxyl group of glucocorticoid changes its solubility into hydrophilicity from hydrophobicity and, as with glucocorticoid glucuronides as a moving object in vivo, it is conceivable that it exhibits the same behavior. Therefore, glucosylation to the 21-hydroxyl group while maintaining the 11β-hydroxyl group is particularly important, and glucosylation of corticosterone was confirmed by high-resolution mass spectrometry and 1D (1H and 13C) and 2D (COSY, ROESY, HSQC-DEPT and HMBC) NMR. Moreover, the difference in bioactivity between corticosterone and corticosterone 21-glucoside was investigated in vitro. Corticosterone 21-glucoside showed greater neuroprotective effects against H2O2-induced cell death and reactive oxygen species (ROS) compared with corticosterone. These results for the first time demonstrate that bioconversion of corticosterone through the region-selective glucosylation of a novel compound can present structural potential for developing new neuroprotective agents.

Abstract INTRODUCTION Intracranial tumor is a debilitating health burden that cause sever disability. The incidence rate for intracranial tumor is 4.63 per 100,000 populations. Through the development of diagnostic and therapeutic modalities, the survival of intracranial tumor improved although modest. There were several factors such as demographic, clinical, and histopathological affect intracranial tumor survival. However, there were no study about intracranial tumors and factors affecting it survival in Indonesia. This study provides insight of intracranial tumor patients and factor affecting 1-year survival in Cipto Mangunkusumo General Hospital from 2014–2016. METHODS The design of this study is retrospective cohort. The subjects were followed-up 1 year after diagnosis. The data retrieved from Dept. of Neurosurgery and Dept. of Neurology Cipto Mangunkusumo General Hospital neuro-oncology registry. Subjects with intracranial tumors underwent surgery/biopsy were included in this study. The factors analyzed in this study were demography, clinical characteristics, histopathology, and treatment types. Analysis of survival were done with Kaplan-Meier curve and cox regression. RESULTS There were 317 subjects in this study. Overall 1-year survival of intracranial tumors were 75.4%. There was increased risk of death (HR 1.88; CI95% 1.2–2.94; p = 0.005) in subjects >46 years old. There was no different of risk of death (HR 0.66; CI95% 0.92–1.03; p = 0.067) between men and women. There was no different of risk of death (HR 1.39; CI95% 0.72–2.70; p = 0.333) between supratentorial and infratentorial tumor. There was difference of survival among histopathology (p < 0.001) and therapeutic approaches (p < 0.001). DISCUSSION This is the first study in Indonesia that analyze survival of intracranial tumor. Several factors such as age, histopathology, and therapeutic approaches were found to affect 1-year survival of intracranial tumor. To get a representative insight of intracranial tumor in Indonesia, a larger cohort study should be conducted.

Full textAbstract:
Laurustinus (Viburnum tinus L.), native to the Mediterranean Region, is an evergreen shrub commonly used as a specimen shrub or small tree or used in border plantings. During August 2003, a blight occurred on 2-year-old-plants of laurustinus growing in pots in a nursery in eastern Sicily (Italy). Disease incidence ranged from 2 to 5% across the field. Symptoms included 3 to 4 cm long lesions and the development of white mycelial strands and brown, 1.0 to 1.8 mm, nearly spherical sclerotia on the crown of plants at the soil line that are typical of Sclerotium rolfsii Sacc. The foliage of infected plants wilted, followed by a sudden collapse of the plant. The fungus was consistently isolated on acidified potato dextrose agar (PDA) (pH 4.5) by plating symptomatic tissues that were surface disinfested (1.2% NaOCl) for 1 min. and rinsed in sterile water. Pathogenicity tests were performed by sprinkling 50 sclerotia, obtained from infected oat kernels (2), on the soil surface around the collar of each of 10 healthy, potted 1-year-old plants of laurustinus. Five of the plants were previously wounded on the crown 1.5 cm above or below the soil line with a sterile needle. Five noninoculated plants served as controls. All plants were maintained at 25 ± 2°C and enclosed for 72 hr in polyethylene bags (90 to 95% relative humidity). Blight symptoms similar to those seen in nursery were observed on inoculated plants 20 to 25 days after inoculation, while no symptoms developed on control plants. Koch's postulates were fulfilled by reisolation of the fungus on acidified PDA from all infected laurustinus plants. S. rolfsii was previously recorded on Prague viburnum (Viburnum × pragense L.) as the causal agent of southern blight (1). To our knowledge, this is the first report of southern blight caused by S. rolfsii on laurustinus. References: (1) A. Hagan. Southern blight on flowers, shrubs, and trees.

Full textAbstract:
The aim of this study is to investigate the antimicrobial compounds present in the lichen Usnea albopunctata. Ethyl acetate extract was purified by silica gel column chromatography to obtain a major compound and the chemical structure was characterized by 1H-NMR, 13C-NMR, DEPT, 1H-1H COSY, HMQC, HMBC, UV, and HR-MS spectroscopic methods as protolichesterinic acid. The antimicrobial activity was estimated by determination of the minimal inhibitory concentration by the broth microdilution method and agar disc diffusion method against thirteen human pathogenic bacterial and four fungal strains. Protolichesterinic acid recorded significant broad spectrum antimicrobial property. The best antibacterial activity was recorded against K. pneumonia (0.25 μg/mL) and V. cholerae (0.5 μg/mL). Significant antifungal activity was recorded against T. rubrum (0.12 μg/mL), which is significantly better than the standard antifungal agent. Protolichesterinic acid is reported for the first time from Usnea albopunctata. Antifungal activity of protolichesterinic acid against medically important fungi is also reported for the first time. Thus the results of the present study suggest that protolichesterinic acid has significant antimicrobial activities and has the strong potential to be developed as an antimicrobial drug after further clinical evaluation.
