Acarbose, an alpha-glucosidase inhibitor used in treating type 2 diabetes, impairs complex carbohydrate digestion and absorption and extends lifespan in mice (without a requisite reduction in food intake). To assess sex-differential effects coincident with calorie restriction versus a non-restricted longevity enhancing intervention, we evaluated the metabolite profiles (by LC/MS) from livers and cecal contents of C57BL/6J mice (n=4/sex/group,) which were maintained for 10 months under one of three diet treatments: ad libitum control diet (CON), ad libitum control diet containing 0...

Aims: Alcoholism may be a cardiovascular risk factor. Osteocyte derived molecules such as fibroblast growth factor 23 (FGF-23) and soluble α Klotho have recently been associated with cardiovascular disease, but their role in alcoholics is unknown. We here analyze the behavior of FGF23 and α Klotho in alcoholics. Methods: Ninety-seven alcoholic patients were assessed for liver function, presence of hypertension, diabetes, atrial fibrillation, left ventricular hypertrophy (LVH), vascular calcifications (assessed by chest X-ray) and nutritional status (lean and fat mass measured by densitometry)...

Endocrine disrupting contaminants, in combination with other environmental variables, are associated with altered reproductive health. Assisted reproductive technology (ART) procedures offer valuable opportunities to explore the connections between environmental contaminants in the ovarian microenvironment and measures of fertility, including impaired responsiveness to gonadotropins. Here, we investigate an emerging class of environmental contaminants, the perfluorinated alkyl acids (PFAAs), to determine whether ovarian contaminant levels are associated with measures of ovarian responsiveness and fertility outcomes in a South Carolina population of women undergoing ART...

Chlorantraniliprole (CAP) is a newly developed insecticide widely used in rice fields in China. There has been few studies evaluating the toxicological effects of CAP on soil-associated microbes. An 85-day microcosm experiment was performed to reveal the dissipation dynamics of CAP in three types of paddy soils in subtropical China. The effects of CAP on microbial activities (microbial biomass carbon-MBC, basal soil respiration-BSR, microbial metabolic quotient-qCO2, acid phosphatase and sucrose invertase activities) in the soils were periodically evaluated...

Difenoconazole, as one of the most widely used triazole fungicides, is applied to protect crops, fruits, and vegetables. It has been reported that difenoconazole can enter the environment and impair aquatic organisms, but whether difenoconazole can disrupt the growth hormone (GH) balance in adult zebrafish (Danio rerio) is still unclear. In this study, adult female and male zebrafish were exposed to difenoconazole (0, 5, 50, and 500µg/L) for seven days. The results revealed that the bioaccumulation of difenoconazole and its primary metabolite difenoconazole alcohol in females were both larger than that in males...

Marine ecosystems are subjected to a variety of contaminants. Antifouling paints, for example, have been extensively used to protect ship surfaces from marine biofouling, but their toxicity has generated great concern. Thus, we evaluated the effect of the biocide chlorothalonil on the immune system of Perna perna mussels. The mussels were exposed to 0 (control), 0.1μg/L and 10μg/L of chlorothalonil for up to 96h. After 24h and 96h of exposure, the following immune-related parameters were analyzed in the hemolymph of mussels: total hemocyte count, cell adhesion, phagocytic activity, level of reactive oxygen species, cell viability and comet assay...

BACKGROUND: Executive dysfunction is common in substance use disorder (SUD) populations and hinders treatment. We previously found that 50% of residents in SUD therapeutic communities had been hospitalized for head injuries; this was a significant determinant of cognitive impairment. The current study aimed to establish whether cognitive remediation improves executive functions (EFs) and self-regulation in an ecologically valid sample of female residents attending SUD therapeutic community treatment, including those with past head injuries and psychiatric comorbidities...

Guinea pig cytomegalovirus (GPCMV) encodes a homolog pentameric complex (PC) for specific cell tropism and congenital infection. In human cytomegalovirus, the PC is an important antibody neutralizing target and GPCMV studies will aid in the development of intervention strategies. Deletion mutants of the C-terminal domains of unique PC proteins (UL128, UL130 and UL131 homologs) were unable to form a PC in separate transient expression assays. Minor modifications to the UL128 homolog (GP129) C-terminal domain enabled PC formation but viruses encoding these mutants had altered tropism to renal and placental trophoblast cells...

INTRODUCTION: Globally, life expectancy together with multimorbidity and chronic diseases are increasing. This leads to a growing demand for care and hence for healthcare personnel and nurses. To meet this demand, healthcare workers from abroad are increasingly hired. The nurses' workplace in general is characterized by physically and psychologically demanding tasks, while that of migrant and minority nurses is additionally characterized by discriminatory practices. The present knowledge about the health of migrant and minority nurses and the terminology in this context are diverse...

p23 is a small acidic protein with intrinsic molecular chaperone activity. It is best known as a co-chaperone of the major cytosolic molecular chaperone Hsp90. p23 binds the N-terminus of Hsp90 and stabilizes the ATP-bound and N-terminally closed Hsp90 dimer. It is in this configuration that many Hsp90 clients are most stably bound. Considering the important role of p23 in the Hsp90 cycle, it came as a surprise that it is not absolutely essential for viability in the budding yeast or for mouse development. Mice without p23 develop quite normally until birth and then all die perinatally because of immature lungs...

BACKGROUND: Recent systematic reviews have demonstrated that pain associated with knee osteoarthritis (OA) is a complex phenomenon that involves various contributors. People with knee OA exhibit symptoms of impaired body-perception, including reduced tactile acuity, impairments in limb laterality recognition, and degraded proprioceptive acuity. The Fremantle Back Awareness Questionnaire (FreBAQ) was developed to assess body-perception specific to the back in people with chronic low back pain...

Retinal ischemia and pathological angiogenesis cause severe impairment of sight. Oxygen-induced retinopathy (OIR) in young mice is widely used as a model to investigate the underlying pathological mechanisms and develop therapeutic interventions. We compared directly the conventional OIR model (exposure to 75% O2 from postnatal day (P) 7 to P12) with an alternative, accelerated version (85% O2 from P8 to P11). We found that accelerated OIR induces similar pre-retinal neovascularization but greater retinal vascular regression that recovers more rapidly...

Granulibacter bethesdensis is a Gram-negative bacillus described as a pathogen exclusively in patients with chronic granulomatous disease (CGD), a phagocytic disorder that impairs the ability to clear catalase-producing organisms. Granulibacter usually causes chronic and recurrent lymphadenopathies. We report the fatal case of a 4-year-old boy with CGD, who presented with sepsis after a few days of abdominal pain and diarrhea.

BACKGROUND: Congenital cytomegalovirus infection (cCMV) is the most common congenital infection worldwide and can lead to long-term impairments such as developmental delay. It is currently unknown how this affects the daily life of children and their parents. METHODS: Children with cCMV were identified by testing stored dried blood spots of 31.484 five-year-old children born in 2008 in the Netherlands. Parents of 133 children with cCMV and 274 children without cCMV participated and filled in questionnaires on the child's development, the child's and parents' quality of life, care provided for the children, and consequences of cCMV on daily life...
