Interruption of HBV intrauterine transmission： A clinical study

AIM: To investigate the effect of hepatitis B virus (HBV)specific immunoglobin (HBIG) and lamivudine on HBV intrauterine transmission in HBsAg positive pregnant women.METHODS: Each subject in the HBIG group (56 cases)was given 200 IU HBIG intramuscularly (im.) every 4weeks from 28-week (wk) of gestation, while each subject in the lamivudine group (43 cases) received 100 mg lamivudine orally (po.) every day from 28-wk of gestation until the 30th day after labor. Subjects in the control group (52 cases) received no specific treatment. Blood specimens were tested for HBsAg, HBeAg, and HBV-DNA in all maternities at 28-wk of gestation, before delivery, and in their newborns 24 hours before the administration of immune prophylaxis.RESULTS: Reductions of HBV DNA in both treatments were significant (P＜0.05). The rate of neonatal intrauterine HBV infection was significantly lower in HBIG group (16.1%)and lamivudine group (16.3 %) compared with control group (32.7 %) (P＜0.05), but there was no significant difference between HBIG group and lamivudine group (P＞0.05). No side effects were found in all the pregnant women or their newborns.CONCLUSION: The risk of HBV intrauterine infection can be effectively reduced by administration of HBIG or Lamivudine in the 3rd trimester of HBsAg positive pregnant women.
Hydrogen sulfide modulates IL-6/STAT3 pathway and inhibits oxidative stress, inflammation, and apoptosis in rat model of methotrexate hepatotoxicity

Methotrexate (MTX) is a commonly used anticancer and immunosuppressive agent. However, MTX can induce hepatotoxicity due to oxidative stress, inflammation, and apoptosis. Hydrogen sulfide (H2S), the endogenous gaseous molecule, has antioxidant, anti-inflammatory, and anti-apoptotic effects. The present work explored the probable protective effect of H2S against MTX hepatotoxicity in rats and also the possible mechanisms underlying this effect. MTX was given at a single intraperitoneal (i.p.) dose of 20 mg/kg. Sodium H2S (56 µmol /kg/day, i.p.), as H2S donor, was given for 10 days, starting 6 days before MTX administration. H2S significantly reduced serum alanine aminotransferase, hepatic malondialdehyde, interleukin 6, nuclear factor κB p65, cytosolic cytochrome c, phosphorylated signal transducer and activator of transcription 3, and Bax/Bcl-2 ratio and significantly increased hepatic total antioxidant capacity and endothelial nitric oxide synthase (eNOS) in rats received MTX. In addition, H2S minimized the histopathological injury and significantly decreased the expression of STAT3 in liver tissue of MTX-challenged rats. The effects of H2S were significantly antagonized by administration of glibenclamide as KATP channel blocker, Nω-nitro-l-arginine, as eNOS inhibitor, or ruthenium red, as transient receptor potential vanilloid 1 (TRPV1) antagonist. It was concluded that H2S provided significant hepatoprotection in MTX-challenged rats through its antioxidant, anti-inflammatory, anti-apoptotic effects. These effects are most probably mediated by the ability of H2S to act as IL-6/STAT3 pathway modulator, KATP channel opener, eNOS activator, and TRPV1 agonist.
The prognostic roles of and correlation between ALK and MYCN protein expression in neuroblastoma

Aims To investigate the relations between anaplastic lymphoma kinase (ALK) and v-myc myelocytomatosis viral related oncogene neuroblastoma derived homolog (MYCN) protein expression and their prognostic roles in neuroblastoma tumours. Methods Sixty-one neuroblastoma tumours obtained at diagnosis were stained with anti-MYCN and anti-ALK antibodies by immunohistochemical staining. The correlations between protein expression of MYCN, ALK and clinicopathological and biological variables of neuroblastoma tumours were analysed. Results High expression of ALK protein could be detected in 25 (41%) and high expression of MYCN protein could be detected in 24 (39.3%) of the 61 neuroblastoma tumours, respectively. The majority of neuroblastoma tumours with evident of ALK or MYCN protein high expression exhibited undifferentiated or poorly differentiated histology (30/35, 85.7%). ALK or MYCN protein high expression in neuroblastoma tumours was associated with adverse clinical prognostic factors and ALK protein high expression was significantly associated with MYCN protein high expression. In addition, either ALK or MYCN protein high expression in neuroblastoma tumours was the independent adverse prognostic factor and also predicted worse survival outcomes for neuroblastoma patients with MYCN non-amplified status or non-high-risk Children’s Oncology Group grouping. Conclusions Our study showed a novel coordinately prognostic role of ALK and MYCN protein expression in neuroblastoma and is the first report to demonstrate the correlation between ALK and MYCN protein expression in primary neuroblastoma tumours.
Virulence and DNA fingerprinting analysis of Xanthomonas oryzae pv. oryzae identify a new pathotype in Guangxi, South China

Bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most destructive diseases affecting rice worldwide. However, little is known about the population structure of this organism in Guangxi Zhuang Autonomous Region, South China. Here, pathotypic and DNA fingerprint analyses were conducted to characterize the isolates of Xoo collected from rice leaves in five districts of the region from 2013 to 2016. Their pathogenicity was tested by leaf clipping, and the DNA fingerprints were analyzed by repetitive sequence‐based polymerase chain reaction and endogenous insertion sequence element‐based polymerase chain reaction assays using the repetitive extragenic palindromic sequence and enterobacterial repetitive intergenic consensus primers, respectively. Pathogenicity assays of 70 representative isolates were conducted using a series of near‐isogenic lines and two new pathotypes were identified. All the pathotypes were found to be incompatible with xa5 and Xa7. One pathotype was virulent to Xa14, Xa21, and Xa23, whereas another virulent to Xa21 and Xa23, but incompatible with Xa14. A dendrogram generated for the data sets obtained from DNA fingerprinting suggested the prevalence of high genetic diversity of Xoo throughout Guangxi, and no association between the molecular haplotypes and pathotypes was identified.
Mechanisms of Weight Loss After Sleeve Gastrectomy and Adjustable Gastric Banding: Far More Than Just Restriction

Obesity has reached global epidemic proportions in recent decades. Bariatric surgery is currently accepted as most effective in alleviating morbid obesity and related disorders. Sleeve gastrectomy (SG) and adjustable gastric banding (AGB) have gained popularity since the beginning of this century because of their efficacy, safety, and simplicity. SG, in particular, has emerged as the most popular bariatric procedure because of its simpler concept and shorter operative time compared with gastric bypass. Caloric restriction, however, cannot account for the sustained weight loss and improved glucose metabolism seen following SG and AGB. Other mechanisms, including changes in gastrointestinal hormone secretion, rearrangement of hypothalamic and vagal control, alteration in energy expenditure, and re‐regulation of bile acid metabolism and the intestinal flora environment, are thought to contribute to the postoperative benefits. This review focuses on clinical and experimental literature addressing the potential mechanisms for SG and AGB procedures in human and animal models. Understanding such mechanisms can provide important insight into how current gastric restrictive procedures work and how future treatments of obesity, both surgical and nonsurgical, can be developed.
RTS,S/AS01 vaccine (Mosquirix™): an overview

ABSTRACT Malaria is an illness caused by Plasmodium parasites transmitted to humans by infected mosquitoes. Of the five species that infect humans, P. falciparum exacts the highest toll in terms of human morbidity and mortality, and therefore represents a major public health threat in endemic areas. Recent advances in control efforts have reduced malaria incidence and prevalence, including rapid diagnostic testing, highly effective artemisinin combination therapy, use of insecticide-treated bednets, and indoor residual spraying. But, reductions in numbers of cases have stalled over the last few years, and incidence may have increased. As this concerning trend calls for new tools to combat the disease, the RTS,S vaccine has arrived just in time. The vaccine was created in 1987 and began pilot implementation in endemic countries in 2019. This first-generation malaria vaccine demonstrates modest efficacy against malaria illness and holds promise as a public health tool, especially for children in high-transmission areas where mortality is high.
Broccoli sprouts juice prevents lens protein aggregation in streptozotocin-induced diabetic rat.

AIM To investigate the effect of broccoli sprouts juice in preventing lens protein aggregation in diabetic rat model. METHODS Totally 25 male Wistar rats were divided into negative control group, diabetic group without juice treatment as positive control and diabetic group given broccoli sprouts juice 0.25, 0.5 and 1 g/d for 28d. Diabetic rat model was obtained by administering a single dose streptozotocin 65 mg/kg intraperitoneal. At the end of the study, all rats were examined for fasting blood sugar level (FBS), visual cataract score using slit lamp biomicroscope and lens αB-crystallin expression using Western blot method. Statistical analysis was performed using one way ANOVA with post hoc test, correlation test, and simple linear regression. RESULTS Positive control group had the highest cataract score and lens aggregated αB-crystallin expression. Broccoli sprout juice dose of 1 g/d group had the mildest cataract score, as well as the expression of lens aggregated αB-crystallin compared to treatments groups 1 and 2, opposite to lens native αB-crystallin expression. The broccoli sprout juice groups gave a significant decrease in cataract score, and also in lens aggregated αB-crystallin expression in diabetic rat models (P<0.05). CONCLUSION Broccoli sprout juice has a significant effect in preventing lens protein aggregation in diabetic rat model. The higher dose gives better visual cataract scores, lower lens aggregated αB-crystallin expression and higher lens native αB-crystallin expression.
Therapeutic effects of modafinil in ischemic stroke; possible role of NF-κB downregulation

Abstract Background: The phenomenon of ischemic stroke receives maximal attention nowadays. Many studies are designed to discover new therapies for reducing debilitating consequences of this disorder. Development of stroke-related tissue damage is due to the combination of blood flow occlusion and reperfusion phase. Inflammatory pathways participate in excess oxidative stress formation after reperfusion. Modafinil is a well-known medication prescribed for sleep disorders. Recently, several studies have focused on finding new indications for modafinil treatment. Anti-inflammatory effects of modafinil through disrupting NF-κB signaling pathway is reported previously. Downregulation of inflammatory cytokines and further oxidative damage have also been mentioned in various experiments. So far, no specific experiment had been conducted to assess the anti-inflammatory effects of modafinil on ischemic stroke. Material and methods: We evaluated outcomes of acutely administered modafinil on post-stroke behaviors and histopathological features (including apoptotic caspase-3 expressing neurons) through bilateral common carotid artery occlusion in rats. Alterations in concentrations of TNFɑ and IL-1β were assessed, together with malon di-aldehyde (MDA) to represent oxidation level. Western blotting was used to reveal the involvement of NF-κB downregulation. Considering possible alterations in blood flow and neuronal metabolism, we also assessed the effects of modafinil on cerebral glucose metabolism through PET scan. Results and discussion: Modafinil exhibited promising effects on remission of behavioral deficits and the number of degenerated neurons in ischemic hippocampus CA1 region. IL-1β and MDA levels were downregulated in treated animals. However, no significant alteration was observed in PET results and TNFɑ between treated and non-treated ischemic brains. Decreased protein levels of NF-κB was also measured in modafinil treated animals. Conclusion: Our findings demonstrate a promising therapeutic effect of modafinil for animal models of stroke.
A magnitude financeira dos eventos adversos em hospitais no Brasil

ABSTRACT Aim: To estimate how much is spent on patients suffering Adverse Events (AEs) in hospitals in Brazil, using financial information available in the National Health Service Hospital Information System (SIH-SUS). Methodology: Exploratory descriptive study of total expenditure associated with occurrence of AEs in hospitals in Brazil. The data sources used were information collected in incidence studies of AEs in hospitals (baseline study) and information recorded in the SIH-SUS. These sources were then linked. The study population was inpatients at public teaching hospitals in Rio de Janeiro State in 2003. A simple random sample of 622 patient records was selected. The costs associated with adverse events were estimated from the additional days stay resulting from AEs established by medical review, length of hospital stay and financial data from the SIH-SUS. Results: The patient records showed that 583 patients had not suffered and 39 (6.3 %) had suffered an AE. Of the total number of cases of AE, 25 (64.1 %) were considered to have been avoidable. The mean amount paid (R$ 3,195.42) for care to patients with AE was 200.5 % higher than the amount paid for patients with no AE, while the mean amount paid to patients with avoidable AE (R$1,270.47) was only 19.5 % higher than the mean amount paid to patients with no AE. Meanwhile the amount paid to patients with an unavoidable AE (R$ 6,632.84) was 523.8 % higher than the mean amount paid to patients with no AE. Mean hospital stay among patients with an AE was 28.3 days longer than among patients with no AE. When extrapolated to total admissions at the two hospitals, AEs entailed expenditure of R$ 1,212,363.30, representing 2.7 % of total reimbursements.
Effects of pelvis-shoulders torsional separation style on kinematic sequence in golf driving

ABSTRACT The golfer’s body (trunk/arms/club) can be modeled as an inclined axle-chain system and the rotations of its parts observed on the functional swing plane (FSP) can represent the actual angular motions closely. The purpose of this study was to investigate the effects of pelvis-shoulders torsional separation style on the kinematic sequences employed by the axle-chain system in golf driving. Seventy-four male skilled golfers (handicap ≤ 3) were assigned to five groups based on their shoulder girdle motion and X-factor stretch characteristics: Late Shoulder Acceleration, Large Downswing Stretch, Large Backswing Stretch, Medium Total Stretch, and Small Total Stretch. Swing trials were captured by an optical system and the hip-line, thorax, shoulder-line, upper-lever, club, and wrist angular positions/velocities were calculated on the FSP. Kinematic sequences were established based on the timings of the peak angular velocities (backswing and downswing sequences) and the backswing-to-downswing transition time points (transition sequence). The backswing and transition sequences were somewhat consistent across the groups, showing full or partial proximal-to-distal sequences with minor variations. The downswing sequence was inconsistent across the groups and the angular velocity peaks of the body segments were not significantly separated. Various swing characteristics associated with the separation styles influenced the motion sequences.
Clinicopathological risk factors for gastric cancer: a retrospective cohort study in China

Objective To examine the potential clinicopathological factors affecting the prognosis of patients with gastric cancer after surgical treatment in China. Methods Between 1 January 2001 and 31 December 2012, a total of 716 patients aged 22–84 years with gastric cancer were enrolled in the study. Survival analysis techniques including log rank test and Cox proportional hazard regression model were applied to evaluate the prognostic significance of clinicopathological characteristics in terms of survival time. Results Of the 24 demographic and pathological variables collected in the data, 16 prognostic factors of gastric cancer were found to have statistically significant influences on survival time from the unadjusted analyses. The adjusted analysis furtherly revealed that age, age square, lymph node metastasis rate group, tumour size group, surgical type II, number of cancer nodules, invasion depth group and the interaction between surgical type II and tumour size group were important prognosis and clinicopathological factors for gastric cancer in Chinese. Conclusion Our study with relatively large sample size and many potential risk factors enable us to identify independent risk factors associated with the prognosis of gastric cancer. Findings from the current study can be used to assist clinical decision-making, and serve as a benchmark for the planning of future prognosis and therapy for patients with gastric carcinoma.
Examining the effects of creatine supplementation in augmenting adaptations to resistance training in patients with prostate cancer undergoing androgen deprivation therapy: a randomised, double-blind, placebo-controlled trial

Introduction Creatine supplementation has consistently been demonstrated to augment adaptations in body composition, muscle strength and physical function in a variety of apparently healthy older adults and clinical populations. The effects of creatine supplementation and resistance training in individuals with cancer have yet to be investigated. This study aims to examine the effects of creatine supplementation in conjunction with resistance training on body composition, muscle strength and physical function in prostate cancer patients undergoing androgen deprivation therapy. Methods and analysis This is a randomised, double-blind, placebo-controlled trial designed to examine the effects of creatine supplementation in addition to resistance training in patients with prostate cancer receiving androgen deprivation therapy. Both supplement and placebo groups will receive a 12-week supervised exercise programme comprising resistance training undertaken three times per week. The primary endpoint (fat-free mass) and secondary endpoints (fat mass, per cent body fat, physical fitness, quality of life and blood biomarkers) will be assessed at baseline and immediately following the intervention. Ethics and dissemination The Human Research Ethics Committee of Edith Cowan University approved this study (ID: 22243 FAIRMAN). If the results of this trial demonstrate that creatine supplementation can augment beneficial adaptations of body composition, physical function and/or psychosocial outcomes to resistance training, this study will provide effect sizes that will inform the design of subsequent definitive randomised controlled trials. The results of this study will be published in peer-reviewed journals and presented at various national and international conferences. Trial registration number ACTRN12619000099123
Green tea and coffee intake and risk of cognitive decline in older adults: the National Institute for Longevity Sciences, Longitudinal Study of Aging

Abstract Objective: To examine the association between green tea and coffee intake and cognitive decline in older adults. Design: A prospective cohort study. The average intake of green tea and coffee in the previous year was assessed through a dietitian interview using a dietary questionnaire. A Mini-Mental State Examination (MMSE) was conducted up to six times biennially. Cognitive decline was screened using the MMSE; its incidence was defined as the first time a score of <27 points was obtained in a biennial test from the baseline. Hazard ratios for incidence of cognitive decline were estimated according to the intake of the two beverages using multivariable Cox proportional hazard regression, controlling for sociodemographic and lifestyle factors. Setting: The National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA) in Japan. Participants: Men (n 620) and women (n 685), aged 60–85 years, from the NILS-LSA. Results: During a mean of 5·3 (sd 2·9) years of follow-up, 432 incident cases of cognitive decline were observed. Compared with participants who consumed green tea <once/d, the multivariable hazard ratio (95 % CI) was 0·70 (0·45, 1·06), 0·71 (0·52, 0·97) and 0·72 (0·54, 0·98) among those who consumed green tea once/d, 2–3 times/d and ≥4 times/d, respectively (Ptrend < 0·05). No significant association was found between coffee intake and cognitive decline. Conclusions: The intake of green tea, but not coffee, was shown to reduce the risk of cognitive decline in older adults.
Gephebase, a database of genotype–phenotype relationships for natural and domesticated variation in Eukaryotes

Gephebase is a manually-curated database compiling our accumulated knowledge of the genes and mutations that underlie natural, domesticated and experimental phenotypic variation in all Eukaryotes — mostly animals, plants and yeasts. Gephebase aims to compile studies where the genotype-phenotype association (based on linkage mapping, association mapping or a candidate gene approach) is relatively well supported or understood. Human disease and aberrant mutant phenotypes in laboratory model organisms are not included in Gephebase and can be found in other databases (eg. OMIM, OMIA, Monarch Initiative). Gephebase contains more than 1700 entries. Each entry corresponds to an allelic difference at a given gene and its associated phenotypic change(s) between two species or between two individuals of the same species, and is enriched with molecular details, taxonomic information, and bibliographic information. Users can easily browse entries for their topic of interest and perform searches at various levels, whether phenotypic, genetic, taxonomic or bibliographic (eg. transposable elements, cis-regulatory mutations, snakes, carotenoid content, an author name). Data can be searched using keywords and boolean operators and is exportable in spreadsheet format. This database allows to perform meta-analysis to extract general information and global trends about evolution, genetics, and the field of evolutionary genetics itself. Gephebase should also help breeders, conservationists and others to identify the most promising target genes for traits of interest, with potential applications such as crop improvement, parasite and pest control, bioconservation, and genetic diagnostic.
