Introduction. Group A Rotavirus (RVA) is known to be a major cause of acute gastroenteritis (AGE) in children but its role as a potential pathogen in immunocompetent adults is probably underestimated.Aim. To compare RVA infections in patients from different age groups.Methodology. Fecal samples were collected from patients aged from birth to 65 years, hospitalized or consulting for AGE between 2015 and 2017. All samples were screened by RT-PCR for the detection of VP6 gene specific of RVA. RVA-positive samples were VP7 and VP4 genotyped using multiplex semi-nested RT-PCR. Full-length VP7 gene of G9-positive strains were sequenced and submitted for phylogenetic analysis.Results. Of 1371 stool specimens collected from children (5 years highlights the need for continuing surveillance in both pediatric and mature populations.BACKGROUND Holistic health is important to life, perhaps especially for elders. Focus should not only be placed on illness or the physical part of their lives, but the whole person should also be considered, emphasizing the connection of their mind, body, and the environment. OBJECTIVE The aims of this research were to study the factors of the holistic health status (HHS) of the Thai elderly in the 21st century, and to predict the factors affecting the development of HHS in 3 aspects; physical health status, mental and emotional health status, and the social and environmental health status. METHOD The data were collected from 928 Thai elderly aged 60 and over in the central part of Thailand. The research instrument was a questionnaire whose reliability was confirmed using a Cronbach alpha coefficient of .904. Multiple regression analysis was used for predicting the factors of HHS. RESULTS The results indicated that stress, increased age, gender, and social participation can predict the HHS of Thai elders, and stress can predict each 3 aspects. Therefore, stress prevention activities are very important for enhancing the HHS of Thai elders. CONCLUSION The findings of this research can be used to improve the quality of life of elders in the 21st century.

The neuropathological hallmarks of that disorder are amyloid plaques with the presence of β-amyloid aggregates, intraneuronal tau protein tangles and chronic inflammation. Brain cells such as microglia and astrocytes are inflammatory cells associated to Alzheimer's disease and involved in the production of inflammatory mediators, such as cytokines and chemokines. Chemokines consist of a large family of protein mediators with low molecular weight, which able to control the migration and residence of all immune cells. In pathological conditions, such as Alzheimer's disease, chemokines contribute to the inflammatory response by recruiting T cells and controlling microglia/macrophages activation. METHODS The present study focuses on the role that chemokines and their receptors play in Alzheimer's disease and in processes such as inflammation and oxidative stress. RESULTS Chemokines are important mediators in AD and inflammation. They promote Aβ deposition and TAU hyperphosphorylation aggravating and increasing the progression of AD. Moreover, they affect the processing of senile plaques and produce abnormal TAU phosphorylation. CONCLUSION There is no cure for AD but the therapeutic potential of chemokines to control the development of the disease may be a field of study to consider in the future.

However, the mechanisms by which yokukansan inhibits neuropathic pain are unclear. OBJECTIVE To investigate the molecular effects of yokukansan on neuroinflammation in U373 MG glioblastoma astrocytoma cells, which express a functional high-affinity neurokinin 1 receptor (substance P receptor), and produce interleukin (IL)-6 and IL-8 in response to stimulation by substance P (SP). MATERIALS AND METHODS We assessed the effect of yokukansan on expression of ERK1/2, P38 MAPK, nuclear factor (NF)-κB, and cyclooxygenase-2 (COX-2) in U373 cells by western blot assay. Levels of IL-6 and IL-8 in conditioned medium obtained after stimulation of cells with SP for 24 h were measured by enzyme-linked immunosorbent assay. All experiments were conducted in triplicate. Results were analyzed by one-way ANOVA, and significance was accepted at p less then 0.05. RESULTS Yokukansan suppressed SP-induced production of IL-6 and IL-8 by U373 MG cells, and downregulated SP-induced COX-2 expression. Yokukansan also inhibited phosphorylation of ERK1/2 and p38 MAPK, as well as nuclear translocation of NF-B, induced by SP stimulation of U373 MG cells. CONCLUSION Yokukansan exhibits anti-inflammatory activity by suppressing SP-induced production of IL-6 and IL-8 and downregulating COX-2 expression in U373 MG cells, possibly via inhibition of the activation of signaling molecules, such as ERK1/2, p38 MAPK, and NF-κB.

METHODS AA (20 mg/kg BW) was supplemented orally to the diabetic rats for 42 days. The levels of plasma glucose, hemoglobin (Hb), glycosylated hemoglobin (HbA1c) insulin and renal function markers, carbohydrate metabolic enzymes in the kidney and insulin signaling molecules in skeletal muscle were measured. RESULTS The administration of AA elicited a significant decrease in the levels of plasma glucose, insulin resistance, HbA1c, urea, uric acid, creatinine, glycogen, glycogen synthase, glucose-6-phosphatase, and fructose-1,6-bisphosphatase and a significant increase of body weight development, insulin, Hb, hexokinase, and glycogen phosphorylase and mRNA expressions of insulin signaling molecule like insulin receptor 1, insulin receptor 2 and glucose transporter-4 in the STZ-NAD induced diabetic rats. Further, the protective effect of AA was evidenced by its histological annotation of the kidney tissues. CONCLUSION Hence, this study concluded that AA can protect against renal dysfunction by attenuating carbohydrate metabolic disorder and subsequently enhances glucose utilization and renal function in STZ-NAD-induced diabetic rats.

This may be due to reasons beyond their pure hypotensive effect. This study aimed to systematically review the association between the use of Angiotensin-Receptor Blockers (ARBs)and the incidence of Alzheimer's Disease (AD). selleck chemicals llc METHODS We systematically searched studies reporting the association between ARB use and incidence of AD. RESULTS Ten studies (1 RCT, 2 case-control studies and 7 cohort studies) met the inclusion criteria. When all observational studies (9) were analyzed, ARB use was associated with a reduced risk of incident AD (HR 0.72, 95% CI 0.58-0.88, p less then 0.001). In the only RCT, the decrease in the incidence of AD was also significant (HR= 0.31,95% CI0.14-0.68). CONCLUSION ARB use may reduce the risk of incident AD. This association does not imply causation and further research is required to clarify potential mechanisms.

BACKGROUND Prediction of molecules crossing BBB remain a challenge in drug delivery. Predictive models are designed for evaluation of set of preclinical drugs which may serve as alternatives for determining BBB permeation by experimentation. OBJECTIVE The objective of present study was to generate QSPR models for permeation of CNS molecules across BBB and its validation using existing in-house leads. METHOD The present study envisaged the determination of set of molecular descriptors which are considered significant correlative factors for BBB permeation property. Quantitative Structure Property Relationship (QSPR) approach was followed to describe the correlation between identified descriptors for 45 molecules and highest, moderate and least BBB permeation data. The molecular descriptors were selected based on drug likeness, hydrophilicity, hydrophobicity, polar surface area, etc. of moleculeence Publishers; For any queries, please email at epub@benthamscience.net.BACKGROUND Hospital acquired (HA) infections are caused due to E. coliwhich is resistant to multiple drugs particularly to fluroquinolone class of drugs. Urinary tract infections (UTI) affects people in the community and in hospitals. 150 million people per annum are suffering from UTI worldwide. METHODS In this present study we designed 36 novel coumarin derivatives, also we predicted pharmacokinetic and toxicity parameters. Docking studies were also carriedand all the compounds were evaluated for antibacterial activity againstresistant quinolone E. coli strain ATCC 25922. It was interesting to note thatthe introduction of electron withdrawing group on the aromatic ringresulted in compounds with increased antibacterial activity which is observed in compound 6 (with4-nitro substitution), compound 23(chloro) and compound 30(chloro, nitro). RESULTS From the MIC results, was observed that compounds 6, 23 and 30 showed higher activity with 0.5µg/ml, 0. 12 µg/ml, 0.5 µg/mlrespectively. Docking studies were performed with the activesite of DNA gyrase (PDB ID 4CKK ).The maximum binding energy was found to be -10.7Kcal/mol. CONCLUSION From the study it was found that 3 compounds were potentially active against quinolone resistant E. coli strains. This study can be further extended for in vivo evaluation.
