A new yeast strain with promising probiotic traits was isolated from the Red Sea water samples. The isolate (YMHS) was subjected to genetic characterization and identified as Cryptococcus sp. Nucleotide sequence analysis of the rRNA gene internal transcribed spacer regions showed 95% sequence similarity between the isolate and Cryptococcus albidus. Cryptococcus sp. YMHS exhibited desirable characteristics of probiotic microorganisms; it has tolerance to low pH in simulated gastric juice, resistance to bile salts, hydrophobic characteristics, broad antimicrobial activity, and in vitro ability to degrade cholesterol...

Influenza A(H1N1)pdm09 virus continues to circulate worldwide without evidence of significant antigenic drift between 2009 and 2016. By using escape mutants, we previously identified six haemagglutinin (HA) changes (T80R, G143E, G158E, N159D, K166E and A198E) that were located within antigenic sites. Combinations of these mutations were introduced into the A(H1N1)pdm09 HA plasmid by mutagenesis. Reassortant 6 : 2 viruses containing both the HA and NA genes of the A(H1N1)pdm09 and the six internal gene segments of A/PR/8/34 were rescued by reverse genetics...

BACKGROUND: Recent studies suggest that the protective effect of the current influenza vaccine could be influenced by vaccination in previous seasons. We estimated the combined effect of the previous and current influenza vaccines from the 2010-2011 season to the 2015-2016 season in Spain. METHODS: We performed a test-negative case-control study in patients ≥9 years old. We estimated the influenza vaccine effectiveness (IVE) against influenza A(H1N1)pdm09, A(H3N2), and B virus...

BACKGROUND AND OBJECTIVES: Body mass index (BMI) is widely used as a surrogate measure of adiposity. The relationship between BMI and body fatness varies by race, sex, and age and more variations have been found among children. This study investigated the relationship between BMI and fat mass among 3-5 year old children having different nutritional status. METHODS AND STUDY DESIGN: A cross-sectional study was conducted in 15 daycare centers in central Thailand. 137 healthy preschool children were recruited according to their nutritional status: thin [BMI for age Z scores, (BAZ) <-2 SD], normal BMI (-2 SD<= BAZ <=+2 SD), overweight/obese (BAZ >+2 SD), and stunted [height for age Z scores < -2 SD]...

Human biomonitoring, i.e. the determination of chemicals and/or their metabolites in human specimens, is the most common and potent tool for assessing human exposure to pesticides, but it suffers from limitations such as high costs and biases in sampling. Wastewater-based epidemiology (WBE) is an innovative approach based on the chemical analysis of specific human metabolic excretion products (biomarkers) in wastewater, and provides objective and real-time information on xenobiotics directly or indirectly ingested by a population...

A passive sampling device, the Polar Organic Chemical Integrative Sampler (POCIS), was calibrated in-situ over a 4-week period in Oslo (Norway) for 10 illicit drugs and pharmaceuticals with the goal of developing an approach for monitoring long-term wastewater drug loads. The calibrations were performed in triplicate using three different overlapping calibration sets under changing environmental conditions that allowed the uncertainty of the sampling rates to be evaluated. All 10 compounds exhibited linear uptake kinetics and provided sampling rates of between 0...

La mayoría de las especies del género Dermestes (Coleoptera: Dermestidae) son carroñeras durante la fase larvaria y la fase adulta, con preferencia por la materia orgánica seca. Debido a esto, los derméstidos son indicadores potencialmente útiles en las investigaciones forenses que impliquen restos humanos momificados y/o esqueléticos. Lamentablemente, los datos de referencia sobre el desarrollo de la mayoría de las especies de Dermestes de relevancia forense son escasos. Este estudio analiza el efecto de cinco temperaturas constantes (15, 20, 25, 30 y 35 °C) sobre la supervivencia y la tasa de desarrollo de tres de los derméstidos de mayor relevancia forense: Dermestes frischii Kugelan, Dermestes maculatus De Geer y Dermestes undulatus Brahm...

The mechanism of celecoxib cardiovascular adverse events was earlier investigated; yet in-depth investigations are needed to assess the involvement of its pro-apoptotic effect throughout this process. An in-vivo chronic rat model of pressure overload employing Nʷ-nitro-l-arginine methyl ester (L-NAME) was tested at different time intervals to ensure the occurrence of persistent myocardial apoptosis along with pressure overload. Seven groups of male Wistar rats were assigned as (i) distilled water; (ii-iv) L-NAME (60 mg/kg) for 6, 12 or 16 weeks; (v-vii) L-NAME [16 weeks] + celecoxib (25, 50 or 100 mg/kg), from week 13 to week 16...

REVIEW
Nick Lane
Chemiosmotic coupling - the harnessing of electrochemical ion gradients across membranes to drive metabolism - is as universally conserved as the genetic code. As argued previously in these pages, such deep conservation suggests that ion gradients arose early in evolution, and might have played a role in the origin of life. Alkaline hydrothermal vents harbour pH gradients of similar polarity and magnitude to those employed by modern cells, one of many properties that make them attractive models for life's origin...

Evaluation of hydrological data obtained between 2000 and 2013 from a time series station in Kuwait Bay (station K6) and an offshore southern location (station 18) off Kuwait showed drastic increase in salinity by 6 units. We tested the hypothesis that increased salinity impacted phytoplankton community characteristics in these semiarid waters. The Arabian Gulf receives seasonal freshwater discharge in the north via Shatt Al-Arab estuary with a peak during March-July. A north to south gradient in the proportion of the freshwater exists between station A in the vicinity of Shatt Al-Arab estuary and station 18 in the southern offshore area...

We have developed pandemic live attenuated influenza vaccines (pLAIV) against clade 1 H5N1 viruses on an Ann Arbor cold-adapted (ca) backbone that induced long-term immune memory. In 2015, many human infections caused by a new clade (2.2.1.1) of goose/Guangdong (gs/GD) lineage H5N1 viruses were reported in Egypt that prompted updating of the H5N1 pLAIV. We explored two strategies to generate suitable pLAIVs: first to modify the hemagglutinin gene of a highly pathogenic wild-type (wt) clade 2.2.1.1 virus A/Egypt/N03434/2009 (Egy/09) (H5N1) with its unmodified neuraminidase (NA) gene; this virus was designated Egy/09 ca The second approach was to select a low pathogenicity avian influenza H5 virus that elicited antibodies that cross-reacted with a broad range of H5 viruses, including the Egypt H5N1 viruses and contained a novel NA subtype for humans...
