Clonorchiasis is caused by the ingestion of raw freshwater fish containing Clonorchis sinensis larvae. Health education is crucial in sustainable control of clonorchiasis but extremely challenging when dealing with adults. To investigate if education in children would be a beneficial long-term approach, a cluster-controlled trial was implemented in two primary schools between 2017 and 2019 in Binyang county, Guangxi, China. A baseline survey was conducted in both schools, and then comprehensive education activities were implemented in the interventional one. Six and 12 months later, all pupils were subjected to a survey to assess the potential change of knowledge, practice and belief related to clonorchiasis. Finally, 247 pupils in interventional school and 151 ones in control were eligible for analysis. In the interventional school, the percentage of pupils with knowledge on transmission route, early symptoms, complications and carcinogenicity increased from 15.0% to 78.5% (p less then 0.001), from 6.5% to 36.8% (p less then 0.001), from 4.0% to 93.9% (p less then 0.001) and from 4.5% to 49.4% (P less then 0.001) after 12 months. In this school, 16 pupils (6.5%) had eaten raw freshwater fish during the year immediately before the baseline survey, a number that decreased to 3 (1.2%) (p=0.002) 12 months later. The percentage of students stating that they would not eat raw freshwater fish in the future was 70.9% at the baseline and 97.2%12 months later (p less then 0.001). Although knowledge related to clonorchiasis also increased in the control school, the absolute percentage of changes was lower; in particular, practice and belief had not changed. V.The banded krait, Bungarus fasciatus is a medically important venomous snake in Asia. The wide distribution of this species in Southeast Asia and southern China indicates potential geographical variation of the venom which may impact the clinical management of snakebite envenomation. This study investigated the intraspecific venom variation of B. fasciatus from five geographical locales through a venom decomplexing proteomic approach, followed by toxinological and immunological studies. The venom proteomes were composed of a total of 9 toxin families, comprising 22 to 31 protein forms at varying abundances. The predominant proteins were phospholipase A2 (including beta-bungarotoxin), Kunitz-type serine protease inhibitor (KSPI) and three-finger toxins (3FTx), which are toxins that cause neurotoxicity and lethality. The venom lethality varied with geographical origins of the snake, with intravenous median lethal doses (LD50) ranging from 0.45-2.55 µg/g in mice. The Thai Bungarus fasciatus monovalent antivenom (BFMAV) demonstrated a dose-dependent increasing immunological binding activity toward all venoms; however, its in vivo neutralization efficacy varied vastly with neutralization efficacy ranging from normalized potency 3 to 28 mg/g, presumably due to the compositional differences of dominant proteins in the different venoms. The findings support that antivenom use should be optimized in different geographical areas. The development of a pan-regional antivenom may be a more sustainable solution for snakebite treatment. V.OBJECTIVE Post-procedure limb compression, hitherto routine following open varicose vein surgery, has been extended to endovenous procedures. However, no robust evidence exists to support this practice. Most of the previous studies have focused on the ideal duration of compression. This study evaluates the clinical and patient reported outcomes with and without post-procedure leg compression following radiofrequency ablation (RFA). METHODS This single centre, prospective, non-inferiority randomised controlled trial recruited adult patients, into two groups (A RFA with compression stocking for two weeks, B RFA alone). The primary outcome was ultrasound determined target vein obliteration at 12 weeks. Secondary outcome measures included a Quality of Life (QoL) score [Aberdeen Varicose Vein Severity Score (AVSS) and Revised Venous Clinical Severity Score (RVCSS)], patient satisfaction, pain score, and complications. RESULTS In total, 100 consecutive patients were recruited (A 51; B 49) classified as clinical cla be required to confirm this conclusion. Crown V. All rights reserved.Seasonal reproduction is common across temperate zone avian species. In these species, physiological and behavioral adaptions have evolved to change according to day length (i.e., seasonally) in order to maximize reproductive output. The hormone prolactin regulates many aspects of parental care, a critical component of reproductive success. Its secretion in birds has been shown to be under photoperiodic control, with the highest levels measured in the spring and summer months, when birds breed and show parental care. However, to date, no study has tested whether the densities of central prolactin binding sites vary seasonally, which may also account for prolactin's effect on parental care. To test this, we collected brains from free-ranging adult male dark-eyed juncos, Junco hyemalis, a biparental songbird, in the spring, summer, and fall, and used quantitative in vitro autoradiography to compare the densities of specific prolactin binding sites across 20 different brain regions. Prolactin binding sites were found in regions that regulate parental behavior in other avian species. During the summer, several hypothalamic regions that regulate parental care, including the preoptic area and tuberal nucleus, contained lower densities of prolactin binding sites, suggesting exposure to higher endogenous prolactin levels, than at other times. This observation is consistent with the fact that circulating prolactin is highest during summer, when males would be providing care to young. Overall, these data suggest that prolactin binding sites are relatively conserved in the avian brain and that central prolactin activity supports parental care efforts in juncos and other avian species. V.Persuasive evidence propose that the toxicity of dopamine in parkinsonism and the loss of dopaminergic neurons are the earliest events during the pathogenesis of Parkinson's disease (PD). In our earlier study, Asiaticoside (AS), a triterpenoid saponin isolated from Centella asiatica was shown to exert a neuroprotective effect against hemiparkinsonism, purportedly due to phosphoinositides (PI)-assisted cytodynamics and synaptic function. Trichostatin A Here, we evaluate AS in the modulation of dopamine (DA), mitochondrial integrity and neurite variations in vitro and motor dysfunctions in vivo. PC12 cells challenged with rotenone-(ROT) (0.1 μM/ml) were exposed to AS and L-DOPA (10 mM and 20 μM/ml respectively). The protein expressions of Bax and Bcl-2 that regulate cell death were assessed following neurite length assays. Rats were distributed into 6 groups (6 rats/group) Sham, Vehicle controls, ROT-infused (6 µg/µl/kg), AS- treated (50 mg/kg/day), Drug control, and ROT + L-DOPA-treated (6 mg/kg/day) groups. At the end of the experimental period, the rats were sacrificed after performing motor behavioral analysis, and the striatum was dissected out. The contents of synaptic vesicular and cytosolic DA were analyzed. Further, the levels of striatal PI were also measured. ROT had caused significant reduction in the neurite outgrowth in the exposed PC12 cells while the tested concentrations of AS and L-DOPA can exert their protective effect on the stunted neurite growth. The levels of Bax, Bcl-2, and cytochrome c which were significantly disturbed by ROT, could also be affected by AS thereby suggesting its effect on neurons. AS treatment caused an improved motor performance, vesicular and cytosolic DA, and striatal PI. These pre-clinical findings force us to speculate that AS could be a potential drug candidate in combating ROT-induced variations that are possibly precipitated by varied vesicular trafficking of DA. V.BACKGROUND Alopecia areata is an autoimmune disease that produces non-scarring hair loss around the body. Gene variants of the cytotoxic T-lymphocyte antigen 4 (CTLA4) gene, a negative regulator of T-cell response, have been associated with a predisposition to autoimmune diseases in different populations; however, the involvement of these genetic variants in the development of AA is controversial. OBJECTIVE The present study evaluated the potential association of two CTLA4 gene variants with alopecia areata in a Mexican population. METHODS We genotyped +49AG (rs231775) and CT60 (rs3087243) variants in 50 AA patients and 100 healthy control participants through PCR-RFLP. RESULTS No statistical difference was observed for either of the gene variants regarding allele or genotype frequencies between AA patients and the controls when the parameters of family/personal history of autoimmune diseases or gender were considered (p>0.05). STUDY LIMITATIONS Small sample size of patients and the data were obtained from Northeast Mexico population. CONCLUSION The genetic variants rs231775 and rs3087243 of the CTLA4 gene are not a risk factor for the development of alopecia areata in the analyzed Mexican population. Pseudomycetoma is an extremely rare deep mycosis, caused by dermatophytic fungi that penetrate the tissue from infected follicles of tinea capitis. Both clinically and histopathology are similar to eumycetoma, being distinguished through the isolation of the fungus, which in the case of pseudomycetoma can be Microsporum spp. or Trichophyton spp. genre. We present a 24 year-old man with an exuberant tumor in the occipital region with fistula, whose histopathological examination evidenced grains composed of hyaline hyphae and the culture for fungi isolated the agent Microsporum canis. Combined treatment of surgical excision followed by oral griseofulvin for two years was performed, with resolution of the condition. Chronic Hepatitis B virus (HBV) infection is endemic worldwide, and the prevalence is especially high in the Asia-Pacific regions. Despite its high prevalence, the literature regarding the impact of HBV infection on subfertility and fertility treatment remains limited and conflicting. Latest studies do not suggest any detrimental effect of HBV infection on the outcome of IVF/ICSI treatment in women having chronic HBV infection. There is evidence that HBV exists in ovarian tissue including oocyte and follicular fluid, and therefore has the potential risk of transmission to the embryo, which can explain the finding of vertical transmission despite immunoprophylaxis. Most recently, we have observed the evidence of HBV viral replication in female HBV carriers undergoing IVF/ICSI treatment. This raises the question of whether antiviral medication should be administered during ovarian stimulation in IVF/ICSI treatment cycles for women with chronic HBV infection to help reduce the chance of vertical transmission. OBJECTIVE Cancer genetic counseling increasingly involves discussing uncertain test results, for example because multiple genes are sequenced simultaneously. This review was performed to provide insight into how counselors' communication of uncertain test results during genetic counseling for cancer affects counselors and counselees. METHODS A systematic mixed studies review was undertaken to review research on the effects of communicating uncertain test results. Four databases were searched using a PICO search strategy. Study findings of articles meeting the inclusion criteria were synthesized narratively. RESULTS Twenty-four articles were included. Uncertain test results encompassed either an inconclusive test result or a variant of unknown significance (VUS). Counselees involved almost exclusively women at risk of hereditary breast and/or ovarian cancer. None of the articles reported effects on counselor outcomes. Counselee outcomes were categorized as cognitive, affective or behavioral. Interpretation of a VUS was overall reported as difficult, and counselees' distress and worry were repeatedly found to decrease over time after the discussion of any uncertain test result.
