T cell differentiation requires appropriate regulation of DNA methylation. In this article, we demonstrate that the methylcytosine dioxygenase ten-eleven translocation (TET)2 regulates CD8(+) T cell differentiation. In a murine model of acute viral infection, TET2 loss promotes early acquisition of a memory CD8(+) T cell fate in a cell-intrinsic manner without disrupting Ag-driven cell expansion or effector function. Upon secondary recall, TET2-deficient memory CD8(+) T cells demonstrate superior pathogen control...

Conserving native biodiversity depends on restoring functional habitats in the face of human-induced disturbances. Low-head dams are a ubiquitous human impact that degrades aquatic ecosystems worldwide. To improve our understanding of how low-head dams impact habitat and associated biodiversity, our research examined complex interactions among three spheres of the total environment. i.e., how low-head dams (anthroposphere) affect aquatic habitat (hydrosphere), and native biodiversity (biosphere) in streams and rivers...

BACKGROUND: Nonfunctioning pancreatic neuroendocrine tumors (NFPanNETs) may be sporadic or inherited because of germline mutations associated with von Hippel-Lindau disease (VHL) or multiple endocrine neoplasia type 1 (MEN1). The clinical behavior of NFPanNETs is difficult to predict, even in tumors of the same stage and grade. The authors analyzed genotype-specific patterns of transcriptional messenger RNA (mRNA) levels of NFPanNETs to understand the molecular features that determine PanNET phenotype...

The Neuse River, North Carolina, U.S., exemplifies a typical de facto potable reuse scenario, where drinking water sources are located downstream of treated wastewater effluent discharges. The study results imply that planned potable water reuse, whether in an indirect or direct potable reuse scenario, might provide better control over water quality than the status quo conditions. Using fluorescence excitation-emission matrix (EEM) measurements, anthropogenic influence of a wastewater treatment plant (WWTP) discharge was observed in samples near the location of drinking water treatment plant (WTP) intakes, eight or more miles downstream of the WWTP, implying that anthropogenic compounds were not fully removed or degraded by natural processes in this reach of the river...

Two actinobacterial isolates, strains SG15(T) and SGB14(T), were recovered through a microbial diversity study of nitrogen fixing nodules from Pisum sativum plants collected in Salamanca (Spain). The taxonomic status of these isolates was determined using a polyphasic approach and both presented chemotaxonomic and morphological properties consistent with their classification in the genus Micromonospora. For strains SG15(T) and SGB14(T), the highest 16S rRNA gene sequence similarities were observed with Micromonospora coxensis JCM 13248(T) (99...

Obesity is becoming an epidemic in Latin American countries. Genetic analyses of endophenotypes for obesity, such as body mass index (BMI), are quite useful for research. In this study, we analysed two functional polymorphisms in the dopamine receptor 4 (DRD4) and dopamine transporter (SLC6A3) genes. A sample of 232 Colombian young subjects were recruited and evaluated for BMI. Two functional polymorphisms in the DRD4 and SLC6A3 and genes were genotyped by PCR and electrophoresis. A significant association was found between BMI and the polymorphisms in DRD4 and SLC6A3 genes...

Treatment choices for acute myeloid leukemia (AML) patients resistant to conventional chemotherapies are limited and novel therapeutic agents are needed. Interleukin-3 receptor alpha (IL-3Rα, or CD123) is expressed on the majority of AML blasts and there is evidence that its expression is increased on leukemic relative to normal hematopoietic stem cells, which makes it an attractive target for antibody-based therapy. Here we report the generation and preclinical characterization of SGN-CD123A, an antibody-drug conjugate utilizing the pyrrolobenzodiazepine dimer (PBD) linker and a humanized CD123 antibody with engineered cysteines for site-specific conjugation...

BACKGROUND: There has been little systematic examination of variation in pediatric burn care clinical practices and its effect on outcomes. As a first step, current clinical care processes need to be operationally defined. The highly specialized burn care units of the Shriners Hospitals for Children system present an opportunity to describe the processes of care. The aim of this study was to develop a set of process-based measures for pediatric burn care and examine adherence to them by providers in a cohort of pediatric burn patients...

Nerve growth factor (NGF) injected into human skin causes local hyperalgesia to mechanical and electrical stimuli lasting for weeks. Pig data suggested axonal sensitization of C-nociceptors as contributing mechanism. Here, we recorded single C- nociceptors in eleven human subjects 3 weeks after intracutaneous injection of 1 µg NGF into the foot dorsum. For each identified unit, the receptive field was mapped and, whenever possible, we recorded two terminal branches of the same unit, one from the hyperalgesic NGF-site ("inside") and the other from the non-sensitized skin ("outside")...

INTRODUCTION: Women at high inherited risk of ovarian cancer are advised to undergo risk-reducing bilateral salpingo-oophorectomy (RRBSO) at age 40-45 years or when their families are complete. Most women are premenopausal at this age, so RRBSO will induce surgical menopause. Despite the clear benefits of RRBSO for cancer risk reduction, much less is known about the impact on non-cancer outcomes that contribute to health and well-being and inform surveillance and management strategies...
