Multidisciplinary management involving expert hepatologists is highly warranted.The interaction of (2R, 3S)-hydroxyleucine (trypsin inhibitor) and β-hydroxyvaline with trypsin has been studied by the steady-state fluorescence spectroscopy. The analysis of fluorescence spectra has revealed the mechanism of binding of these nonprotein amino acids to trypsin. According to the docking (2R, 3S)-hydroxyleucine form hydrogen bonds with trypsin having little effect on tryptophan and tyrosine residues in enzyme molecule. The results obtained in this study indicate that fluorescence of trypsin is quenched at high concentrations of amino acids. Thus fluorescence spectra analysis confirms data obtained by molecular docking.OBJECTIVES The aim of this study was to evaluate lateral pterygoid muscle (LPM) signal intensity changes related to different degrees of disc status groups using magnetic resonance imaging (MRI). METHODS Four groups were established according to disc displacement of examined temporomandibular joint (TMJ) and opposing TMJ. MRI scans were obtained with a 1.5 T device. The signal intensity was measured from the sagittal slice where midportion of the muscle belly was observed. The regions of interest were placed over the superior and inferior heads of LPM. To normalize differences in signal intensity, signal intensity of the grey matter and white matter of the brain was also measured. Signal intensity ratio (SIR) was calculated. Measurements were performed in both T1- and T2-weighted images. RESULTS In the intergroup comparisons, a statistically significant difference was found for SIR1 sup., SIR1 inf., SIR2 sup. and SIR2 inf. variables (p  0.05). For SIR1 sup., SIR1 inf., SIR2 sup. and SIR2 inf. variables, significant differences were found between five binary comparison groups (1-2, 1-3, 2-3, 0-2, 0-3) (p  less then  0.05). CONCLUSION In conclusion, SIR is correlated with the degree of disc displacement. The internal derangement of the opposite joint did not affect SIR of superior and inferior heads of examined LPM in both T1- and T2-weighted images. The inferior head of LPM was also found affected by disc displacement.BACKGROUND Myxidium kudoi Meglitsch, 1937 has been described from the type host, blue catfish Ictalurus furcatus, with no additional host records or molecular data available for this species. PURPOSE To provide molecular data and a novel host locality for this species and carry out phylogenetic analyses to infer the evolutionary relationship of the species to other members of the family Myxidiidae for which DNA sequence data is available. METHODS These data were collected using myxospores from the gallbladder of a blue catfish, Ictalurus furcatus collected from Lake Texoma, Oklahoma, USA. Myxospores were morphologically consistent with the only other account of this species and not any other Myxidium species described from siluriform fishes. RESULTS Myxospores were oblong with rounded ends and were 10.8-12.6 (11.6 ± 0.5) µm in length and 4.7-6.6 (5.7 ± 0.5) µm in width. Polar capsules were subspherical and 2.7-3.9 (3.4 ± 0.3) µm in length and 2.4-3.5 (3.1 ± 0.3) µm in diameter, with each capsule containing a polar filament with 3-4 coils. Molecular data consisted of a 2918-bp sequence of the partial 18S, complete ITS1, 5.8S, ITS2, and partial 28S ribosomal rRNA regions as well as a 2455-bp sequence of partial 28S ribosomal RNA. The partial 18S and 28S data was used in a concatenated Bayesian phylogenetic analysis to further infer the evolutionary relationships of the Myxidiidae. Additionally, the partial 18S data was used in a separate phylogenetic analysis. CONCLUSIONS The present work reports novel morphological and molecular data for Myxidium kudoi as well as a novel locality of occurrence for this species. In concatenated phylogenetic analysis using 18S and 28S data and other molecular data from Myxozoa, M. kudoi grouped with other freshwater Myxidiidae. In the single-locus, 18S analysis, M. kudoi grouped with Myxidium rhodei from Rutilus rutilus and Myxidium amazonense from Corydoras melini, the only other Myxidium species of catfish for which molecular data are available.PURPOSE Sri Lanka is endemic to cutaneous leishmaniasis and reported as the latest focus of leishmaniasis in the Asian subcontinent. Annually, the number of leishmaniasis cases is increasing; therefore, more efficient diagnostic tools, treatment methods and effective prevention measures are indispensable. For this reason, many studies were conducted regarding leishmaniasis infections in Sri Lanka; however, some areas need more attention. Thus, in this review, we comprehensively discussed the studies on leishmaniasis carried out in Sri Lanka. METHODS Published articles on leishmaniasis in Sri Lanka were searched on PubMed, Google Scholar and ResearchGate databases. Inclusion criteria for the articles were based on keyword searches including 'Leishmaniasis in Sri Lanka', 'Leishmaniasis vector in Sri Lanka', 'Sandfly species in Sri Lanka', 'Leishmaniasis epidemiology in Sri Lanka' which are publicly accessible as of 15th July 2019. RESULTS In this study, we evaluated and summarized the leishmaniasis reports in Sri Lanka and mainly focused on clinical presentation of leishmaniasis infection, genetic characteristics of Leishmania donovani Sri Lankan strain, geographical distribution and associated environmental factors, immunological aspects of the infection, vector, reservoir host, risk factors, diagnosis and treatment, and prevention and control. Furthermore, we identified the areas where further research is needed to fill the essential knowledge gaps. CONCLUSIONS Leishmaniasis has become a critically important parasitic infection in Sri Lanka, whereas the significant clinical form is cutaneous leishmaniasis. Prevalence of the leishmaniasis infections is reported from all the districts of the country. Therefore, more studies are essential to be carried out to fill the existing knowledge gaps emphasized in this review.Background A frequent problem in ageing patients, and thus in nursing home residents, is dysphagia, affecting the ability to swallow solid dosage forms. A promising and personalized drug delivery system for this patient group is the orodispersible film. Orodispersible films could be prepared extemporaneously in a (hospital) pharmacy setting or in specialty compounding community pharmacies using the solvent casting method. Little has been done to systematically investigate which medications should be chosen for orodispersible film formulation development. Objective In this study, the medication use of nursing home residents was examined to identify medications that are suitable for orodispersible film formulation development. Setting Nursing homes of three Northern provinces of Netherlands. Method Medication intake data from 427 nursing home residents from nine nursing homes from the three northern provinces of the Netherlands were used to identify candidates for orodispersible film formulation development. A candidates for manufacturing of orodispersible films for the ageing patient population may be the combination of levodopa and carbidopa used to treat the symptoms of Parkinson's disease, and baclofen used to treat spasticity.There has been increased attention to and emphasis on competency-based medical education and the transformation from highly supervised medical students towards independent, entrustable physicians. We explored how program directors (PDs) justify decisions about whether they would trust finishing Post Graduate Year 1 (PGY1) residents to care for the PD or a loved one. Using an end of year survey with validity evidence, we assessed PDs' responses (Yes, No, Not Sure) and written comments about this entrustment decision for USUHS medical students from graduating classes of 2013-2015 (PGY1). We performed a qualitative inductive content analysis to identify themes in how PDs justified their decisions as well as descriptive statistics and a contingency table analysis to examine associations between trust decisions and election to membership in Alpha Omega Alpha (AOA), or conversely, referral to the Student Promotions Committee (SPC) for remediation. Qualitative analyses revealed five themes related to this trust decision about medical residents personal, interpersonal, knowledge, competence, and developmental. Neither AOA status, nor SPC referral status was significantly associated with the trust measure, overall, but positive trust decisions were significantly higher among those elected to AOA than in those who were not. Positive trust decisions were significantly associated with AOA status but negative trust decisions were not significantly associated with referral to the SPC. This study offers insights into what attributes may underpin trust decisions by PDs. Our findings suggest that PDs' frequent use of personal and interpersonal characteristics to justify trust decisions contrasts with the use of clinical and knowledge based assessments during undergraduate medical education (UME), and emphasize the importance of critical intrinsic abilities.The isolation, identification and characterization of a novel huperzine A (HupA)-producing fungal strain Rsp5.2 isolated from Huperzia serrata (Thunb. ex Murray) Trev. in Vietnam. The fifty-eight endophytic fungi were recovered from roots of natural H. Brusatol ic50 serrata in Lao Cai province of northern Vietnam and screened for HupA-producing by thin-layer chromatography (TLC). The only one of the 58 strains, Rsp5.2, could produce HupA. The amount of HupA produced by Rsp5.2 was quantified to be 19.45 µg g-1 dried mycelium by high-performance liquid chromatography (HPLC). Acetylcholine esterase (AchE) inhibition (IC50) of the crude HupA extract from Rsp5.2 fermentation broth was 2.849 ± 0.0026 µg mL-1. The fungus was identified as Fusarium sp. Rsp5.2 by morphological characteristics and Internal Transcribed Spacer (ITS) sequences. This is the first report of Fusarium sp. as a HupA-producing endophyte isolated from H. serrata.BACKGROUND Retained products of conception (RPOC) with hemorrhage need intervention when RPOC persist and remain symptomatic. The safety and efficacy of uterine artery embolization (UAE) for RPOC using gelatin sponge (GS) alone, and fertility after UAE for RPOC remain unknown. The purpose of this study is to retrospectively investigate the efficacy of UAE for RPOC with bleeding and future pregnancy outcomes. METHODS Between 2007 and 2016, 14 patients (mean age, 33 years old) diagnosed as RPOC with bleeding received UAE using GS at our institution. Pregnancy outcomes were vaginal delivery (n = 7), miscarriage (n = 4), and termination (n = 3). Four patients received dilation and curettage/evacuation (D&C/E) for treatment of RPOC before bleeding occurred. The mean time interval from the end of pregnancy to bleeding was 28 days. Technical success, clinical success, complications, angiographic features and fertility after UAE were retrospectively assessed. RESULTS Technical success was achieved in 13 patients (93%) and clinical success was achieved in all 14 patients. No major complications occurred. The angiographic features of RPOC were tortuous feeders with flow into a focal blush of contrast (n = 14). Additional findings were pseudoaneurysm (n = 6), early venous return (n = 4), and extravasation (n = 2). Pseudoaneurysm was observed significantly more often in patients who received D&C/E before UAE compared to those who received conservative treatment alone (P = 0.015). The mean follow-up period was 29 months. Six patients achieved six pregnancies an average of 29 months after UAE. CONCLUSION UAE using GS may be an effective and safe treatment for RPOC with hemorrhage that can preserve fertility.
