Over the past decade, endoplasmic reticulum (ER) stress has emerged as an important mechanism involved in the pathogenesis of cardiovascular diseases including heart failure. Cardiac therapy based on ER stress modulation is viewed as a promising avenue toward effective therapies for the diseased heart. Here, we tested whether sirtuin-1 (SIRT1), a NAD(+)-dependent deacetylase, participates in modulating ER stress response in the heart. Using cardiomyocytes and adult-inducible SIRT1 knockout mice, we demonstrate that SIRT1 inhibition or deficiency increases ER stress-induced cardiac injury, whereas activation of SIRT1 by the SIRT1-activating compound STAC-3 is protective...

During embryogenesis, primordial germ cells (PGCs) and somatic gonadal precursor cells (SGPs) migrate and coalesce to form the early gonad. A failure of the PGCs and SGPs to form a gonad with the proper architecture not only affects germ cell development, but can also lead to infertility. Therefore, it is critical to identify the molecular mechanisms that function within both the PGCs and SGPs to promote gonad morphogenesis. We have characterized the phenotypes of two genes, longitudinals lacking (lola) and ribbon (rib), that are required for the coalescence and compaction of the embryonic gonad in Drosophila melanogaster...

BACKGROUND: In 1987, three unrelated English families were reported with a putative blood subgroup called Apae. Swedish researchers later found evidence leading to abolishment of the Apae subgroup and establishment instead of the FORS blood group system (System 31 - ISBT, 2012). It is important to know the prevalence of antibodies in order to make the best decisions in transfusion medicine. Cells expressing the Forssman saccharide, such as sheep erythrocytes, are needed to detect the anti-Forssman antibody...

Malignancy following solid organ transplant remains a significant threat to the survival of cardiac transplant recipients. Plasma cell dyscrasias including multiple myeloma have been encountered in this population, and medication treatments traditionally used to treat these disorders demonstrate immunomodulatory effects that may have implications on the transplanted allograft. Lenalidomide is an immunomodulatory agent that has been used to treat plasma cell disorders, including light-chain amyloidosis (AL) and multiple myeloma, and represents such a class of medications in which the risks and benefits in the solid organ transplant population remain to be fully elucidated...

Cardiovascular disease (CVD) is the leading cause of mortality for adults in the US, regardless of ethnicity. A cross-sectional correlational design was used to describe and compare CVD risk and cardiac mortality in White Hispanic and non-Hispanic women and men. Data from 3,317 individuals (1,523 women and 1,794 men) hospitalized for non-cardiac causes during 2012-2013, and data from the 2010 United States Census were included. The sex-specific 10-year Framingham General Cardiovascular Risk Score (FRS-10) was used to estimate long-term risk for major cardiac events...

BACKGROUND:  Pediatric acute respiratory distress in tropical settings is very common. Bacterial pneumonia is a major contributor to morbidity and mortality and requires adequate diagnosis for correct treatment. A rapid test that could identify bacterial (vs. other) infections would have great clinical utility. METHODS AND FINDINGS:  We performed RNA-Seq and analyzed the transcriptomes of 68 pediatric patients with well-characterized clinical phenotype to identify transcriptional features associated with each disease class...

Recent improvements in next-generation sequencing (NGS) technology have enabled detection of biomarkers in cell-free DNA in blood and may ultimately replace invasive tissue biopsies. However, a better understanding of the performance of blood-based NGS assays is needed prior to routine clinical use. As part of an IRB-approved molecular profiling registry trial of pancreatic ductal adenocarcinoma (PDA) patients, we facilitated blood-based NGS testing of 34 patients from multiple community-based and high-volume academic oncology practices...

Previous studies have reached conflicting conclusions regarding the proportion of Merkel cell carcinomas (MCCs) that contain the Merkel cell polyomavirus (MCPyV) and the clinical significance of tumor viral status. To address these controversies, we detected MCPyV large T antigen using immunohistochemistry with two distinct antibodies and MCPyV DNA using quantitative PCR. Tumors were called MCPyV-positive if two or more of these three assays indicated presence of this virus. 53 of 282 (19%) MCC tumors in this cohort were virus-negative using this multimodal system...

Varenicline is a nicotinic acetylcholine receptor (nAChR) agonist used to treat nicotine addiction but a live debate persists concerning its mechanism of action in reducing nicotine consumption. Although initially reported as α4β2-selective, varenicline was subsequently shown to activate other nAChR subtypes implicated in nicotine addiction including α3β4. However, it remains unclear whether activation of α3β4 nAChRs by therapeutically relevant concentrations of varenicline is sufficient to affect the behavior of cells that express this subtype...

RNA interference (RNAi) is a genetic technique which has novel application for sustainable pest control. The Sterile Insect Technique (SIT) uses releases of mass-produced, sterile male insects to out-compete wild males for mates to reduce pest populations. RNAi sterilization of SIT males would have several advantages over radiation sterilization, but to achieve this appropriate target genes must first be identified and then targeted with interference technology. With this goal, eight spermatogenesis related candidate genes were cloned and tested for potential activity in Bactrocera dorsalis...

Menopause is a natural event in women´s lives leading to the cessation of menstruation and the reproductive function due to loss of the ovarian follicular function. Menopause-derived estrogen deprivation and related endocrine factors are linked to some symptoms of middle-aged women, such as hot flashes, aches, joint pain, stiffness, depressed mood, bone degeneration, nutritional dysfunction, or difficulty to maintain body mass. Clinical approaches to these problems often involve hormone replacement therapy (HRT) and other modalities of therapeutic intervention...

This study employed a Multi-Attribute Utility (MAU) model to examine the Pap test decision-making process among Pacific Islanders (PI) residing in Southern California. A total of 585 PI women were recruited through social networks from Samoan and Tongan churches, and Chamorro family clans. A questionnaire assessed Pap test knowledge, beliefs and past behaviour. The three MAU parameters of subjective value, subjective probability and momentary salience were measured for eight anticipated consequences of having a Pap test (e...

Policy measures introduced in Spain during the economic crisis included a reduction in public health expenditure and in healthcare entitlements (RDL16/2012), which affected the general population as a whole, but especially immigrants. This paper analyzes changes in immigrants' access to health care during the economic crisis from the perspective of health professionals (medical and administrative) and immigrants. A qualitative descriptive-interpretative study was conducted in Catalonia through individual interviews with a theoretical sample of health professionals (n=34) and immigrant users (n=20)...

With the exception of a limited number of sites in the body, primary tumors infrequently lead to the demise of cancer patients. Instead, mortality and a significant degree of morbidity result from the growth of secondary tumors in distant organs. Tumor survival, growth and dissemination are associated with the formation of both new blood vessels (angiogenesis) and new lymph vessels (lymphagenesis or lymphangiogenesis). Although intensive research in tumor angiogenesis has been going on for the past four decades, experimental results in tumor lymphangiogenesis began to appear only in the last 10 years...

PURPOSE: To explore the functional consequences of possible cross-talk between the CXCR4/CXCL12 and the S1P pathways in multiple myeloma (MM) cells and to evaluate the effect of S1P targeting with FTY720 modulator as a potential anti-MM therapeutic strategy. EXPERIMENTAL DESIGN AND RESULTS: S1P targeting with FTY720 induces MM cell apoptosis. The combination of FTY720 with SPHK1 inhibitor SKI-II results in synergistic inhibition of MM growth. CXCR4/CXCL12-enhanced expression correlates with reduced MM cell sensitivity to both FTY720 and SKI-II inhibitors, and with SPHK1 co-expression in both cell lines and primary MM bone marrow samples, suggesting regulative cross-talk between CXCR4/CXCL12 and SPHK1 pathways in MM cells...
