Honeybees (Apis mellifera) are well-known for their sophisticated division of labor with each bee performing sequentially a series of social tasks. Colony organization is largely based on age-dependent division of labor. While bees perform several tasks inside the hive such as caring for brood ("nursing"), cleaning or sealing brood cells or producing honey, older bees leave to colony to collect pollen (proteins) and nectar (carbohydrates) as foragers. The most pronounced behavioral transition occurs when nurse bees become foragers...

Streptococcus pneumoniae is a gram-positive pathogen that causes otitis media, pneumonia, meningitis, and other serious diseases. Vancomycin is one of the most important drugs currently used for the treatment of gram-positive bacterial infections, representing, importantly, the last line of defense against bacteria that have developed resistance to other antibiotics. While primary efforts of most investigations focused on the antibacterial mechanism of vancomycin, few studies have been performed to assess the tolerance mechanism of bacteria to vancomycin...

Background: Diarrhoea is a common medical problem affecting travellers to Asia, Africa and Latin America. The use of prophylactic antimicrobial agents may increase the risk of contracting resistant bacteria. Findings indicate that oligosaccharides, i.e. carbohydrate chains of 3-10 monosaccharides, reduce the risk of diarrhoea. Methods: We performed a placebo-controlled, double-blind study of a galacto-oligosaccharide, B-GOS (Bimuno®, Clasado Ltd, Milton Keynes UK), vs placebo for participants travelling to countries with a high/intermediate risk of diarrhoea for 7-15 days...

BACKGROUND: Hohla et al. suggested that female gender could positively predict response to FOLFIRINOX in patients with advanced pancreatic cancer. In this study, we explored the response to the FOLFIRINOX regimen by gender within the trial PRODIGE4/ACCORD 11. PATIENTS AND METHODS: Data were described by gender, both in FOLFIRINOX group and in the intention-to-treat population of the trial. The relative effect of gender (females in comparison to males) on overall survival (OS) and progression-free survival was estimated by using a Cox proportional hazard model and was presented with the Hazard Ratio and their 95% confidence interval...

Dichloroacetate (DCA) is an inhibitor of pyruvate dehydrogenase kinase, which promotes the flux of carbohydrates into mitochondria and enhances the aerobic oxidation of glucose. DCA has previously been demonstrated to exhibit antitumor properties. The present study revealed that treatment with DCA induced increased levels of autophagy-associated proteins in esophageal squamous carcinoma cells while minimally affecting apoptosis. The present study examined the localization of light chain (LC)-3 by adenovirus infection with a green fluorescent protein (FP)-red FP-LC3 reporter construction and confirmed that DCA treatment induced significant autophagy...

Group A streptococci (GAS) are genetically diverse. Determination of strain features can reveal associations with disease and resistance and assist in vaccine formulation. We employed whole-genome sequence (WGS)-based characterization of 1,454 invasive GAS isolates recovered in 2015 by Active Bacterial Core Surveillance and performed conventional antimicrobial susceptibility testing. Predictions were made for genotype, GAS carbohydrate, antimicrobial resistance, surface proteins (M family, fibronectin binding, T, R28), secreted virulence proteins (Sda1, Sic, exotoxins), hyaluronate capsule, and an upregulated nga operon (encodes NADase and streptolysin O) promoter (Pnga3)...

In our previous studies, a functionally unknown gene, family with sequence similarity 172, member A (FAM172A), was identified. High levels of FAM172A suppressed the cell cycle process, arresting HepG2 cells in G1/S and inhibiting cell proliferation. The present study aimed to confirm the expression levels of FAM172A and nucleotide-binding protein 1 (NUBP1) in colorectal cancer (CRC) tissues and normal colorectal tissues. The impact of FAM172A and NUBP1 on the prognosis of patients with CRC was also analyzed...

BACKGROUND: Apophysomyces species are prevalent in tropical countries and A. variabilis is the second most frequent agent causing mucormycosis in India. Among Apophysomyces species, A. elegans, A. trapeziformis and A. variabilis are commonly incriminated in human infections. The genome sequences of A. elegans and A. trapeziformis are available in public database, but not A. variabilis. We, therefore, performed the whole genome sequence of A. variabilis to explore its genomic structure and possible genes determining the virulence of the organism...

Reassimilation of internal CO2 via woody tissue photosynthesis has a substantial effect on tree carbon income and wood production. However, little is known about its role in xylem vulnerability to cavitation and its implications in drought-driven tree mortality. Young trees of Populus nigra were subjected to light exclusion at the branch and stem levels. After 40 d, measurements of xylem water potential, diameter variation and acoustic emission (AE) were performed in detached branches to obtain acoustic vulnerability curves to cavitation following bench-top dehydration...

Specific guidelines that aim to facilitate the recovery of soccer players from the demands of training and a congested fixture schedule are lacking; especially in relation to evidence-based nutritional recommendations. The importance of repeated high level performance and injury avoidance while addressing the challenges of fixture scheduling, travel to away venues, and training commitments requires a strategic and practically feasible method of implementing specific nutritional strategies. Here we present evidence-based guidelines regarding nutritional recovery strategies within the context of soccer...

INTRODUCTION: Pancreatic head ductal adenocarcinoma (PDAC) and inflammatory head masses (IHM) related to chronic pancreatitis are often difficult to differentiate. PDAC produces significant inflammatory response with resultant lymphopenia and thrombocytosis. The prognostic role of platelet-lymphocyte ratio (PLR) as a tumor marker has been defined. We aimed to find the role of PLR as a diagnostic marker for PDAC in differentiating benign head mass comparing with carbohydrate antigen 19-9 (CA 19-9)...

The epidemiology of Staphylococcus aureus infections has evolved in recent years, as this species is a major Gram-positive pathogen associated with healthcare services. The antimicrobial resistance of this species raises an urgent need for new treatment strategies. Fruits play important nutritional and economic roles in society, but their biological and pharmacological features are poorly explored when compared to nonedible parts of plants such as barks and leaves. In this study, we show that the cashew apple juice [cashew juice pulp (CJP)] extract is active against the planktonic cells of S...
