OBJECTIVES: Nitrite inhalants (poppers) are commonly used recreational drugs among men who have sex with men (MSM) and were previously associated with elevated rates of high-risk sexual behavior, HIV and HHV-8 seroconversion, and transient immunosuppressive effects in experimental models. Whether long-term popper use is associated with cancer risk among MSM in the HAART era is unclear. DESIGN: Prospective cohort study of cancer risk in 3223 HIV-infected and -uninfected MSM in the Multicenter AIDS Cohort Study from 1996-2010...

BACKGROUND: Pancreas grafts from pediatric donors are still considered "not ideal". Perceived concerns are related to low islet mass and potential for graft thrombosis. METHODS: The study evaluated all pancreas transplants from January 2000 to May 2015 using the Organ Procurement and Transplant Network (OPTN) database. Comparative analysis of recipient and graft survival was performed between pediatric (≤18 years) and adult donors. In the pediatric group, the outcomes were stratified based on donor age (≤ 6 years; 7-12 years; 13-18 years) and weight (<30 kg; 30-95 Kg; >95 kg)...

Shati/Nat8L significantly increased in the nucleus accumbens (NAc) of mice after repeated methamphetamine (METH) treatment. We reported that Shati/Nat8L overexpression in mouse NAc attenuated METH-induced hyperlocomotion, locomotor sensitization, and conditioned place preference. We recently found that Shati/Nat8L overexpression in NAc regulates the dopaminergic neuronal system via the activation of group II mGluRs by elevated N-acetylaspartylglutamate following N-acetylaspartate increase due to the overexpression...

BACKGROUND: To avoid future risk is a definitive goal of long-term asthma management. Exacerbations are considered to be the most relevant future risk in real life asthma management. Few comparative studies have evaluated the risk factors associated with exacerbations in Japanese patients with asthma. METHODS: We performed the prospective 1-year follow up study in Japanese patients with adult asthma. A total of 189 patients with asthma were enrolled and followed up for 1 year...

BACKGROUND AND AIMS: The colonic self-expanding metal stent (SEMS) has been widely used for "bridge to surgery" and palliative therapy. However, if the spread of SEMS is insufficient, not only can a decompression effect not be obtained but also perforation and obstructive colitis can occur. The mechanism of occurrence of obstructive colitis and perforation was investigated by flow dynamics. METHODS: Bernoulli's principle was applied, assuming that the cause of inflammation and perforation represented the pressure difference in the proximal lumen and stent...

BACKGROUND: Polycystic liver disease (PCLD) is characterized by cystic replacement of the hepatic parenchyma, leading to hepatic dysfunction, portal hypertension, and hepatomegaly. Patients with liver dysfunction and/or symptomatic disease are eligible for liver transplantation. However, little is known about these patients' waitlist outcomes relative to others with chronic liver disease. METHODS: We used OPTN/UNOS data from February 27, 2002 to December 31, 2015 to compare waitlist outcomes of adult patients with PCLD to those with chronic liver failure (CLF) and hepatocellular carcinoma (HCC)...

BACKGROUND: Kidney transplantation has been advocated as a therapeutic option in lung recipients who develop end-stage renal disease. This analysis outlines patterns of allograft survival following kidney transplantation in previous lung recipients (KAL). METHODS: Data from the UNOS lung and kidney transplantation registries (1987-2013) were cross-linked to identify lung recipients who were subsequently listed for and/or underwent kidney transplantation. Time-dependent Cox models compared survival in KAL patients vs...

BACKGROUND: Yeasts are a necessary requisite in the diet of most Drosophila species that, in turn, may vector their dispersal in natural environments. Differential attractiveness experiments and the isolation of yeasts consumed by Drosophila may be informative for characterizing this association. Hanseniaspora uvarum is among the most common yeast species isolated from Drosophila crops, with high attractiveness to drosophilids. Saccharomyces cerevisiae has been widely used to collect flies, and it allows broad sampling of almost all local Drosophila species...

Serum amyloid A1 (SAA1) is a sensitive acute phase reactant primarily produced by the liver in response to acute inflammation. We have recently shown that SAA affects proliferation, migration, and invasion of glioblastoma cell lines, which suggest its participation in the malignant process. Consistently, levels of SAA have been used as a non-invasive biomarker for the prognosis of many cancers. In this study, we aimed to investigate SAA serum levels and expression of SAA genes in human astrocytomas tissues...

Cdc7 is a serine-threonine kinase and plays a conserved and important role in DNA replication, and it has been recognized as a potential anticancer target. Herein, we report the design, synthesis and structure-activity relationship of novel furanone derivatives as Cdc7 kinase inhibitors. Compound 13 was identified as a strong inhibitor of Cdc7 with an IC50 value of 0.6 nM in the presence of 1 mM ATP and showed excellent kinase selectivity. In addition, it exhibited slow off-rate characteristics, which may offer advantages over known Cdc7 inhibitors in its potential to yield prolonged inhibitory effects in vivo...

The distributions of 15 nitrated polycyclic aromatic hydrocarbons (NPAHs) in sediments collected at 44 sites throughout Osaka Bay, Japan were examined. The highest total NPAHs, with a concentration of 1949ng/kg dry weight, were detected near the city of Amagasaki. Some sites near the cities of Osaka, Kishiwada, sand Sakai registered ng/kg levels of NPAHs, but individual NPAH concentrations were relatively lower than those in previous studies. The sources were estimated using principal component analysis, and NPAHs were derived from exhaust gases of automobiles and industries at some sites...

Heart transplantation (HT) is a life saving procedure, but a limited donor supply forces the surgeons to prioritize the recipients. The understanding of factors that predict mortality could help the doctors with this task. The objective of this study is to find locally optimal feature sets to predict survival of HT patients for different time periods. To this end, we applied logistic regression together with a greedy forward and backward search. As data source, we used the United Network for Organ Sharing (UNOS) registry, where we extracted adult patients (>17 years) from January 1997 to December 2008...

Common marmosets (Callithrix jacchus) are potentially primate models for preclinical drug metabolism studies because the molecular characteristics of cytochrome P450 (P450) enzymes have similarities between this species and humans. However, characterization of non-P450 enzymes have not been clarified in marmosets. Here, we report characterization of flavin-containing monooxygenase (FMO) 1-5 identified in marmoset tissues. Marmoset FMO forms shared high amino acid sequence identities (93-95%) and phylogenetic closeness with human homologue FMO forms...

BACKGROUND: The approach to the diagnosis and management of Sub-Clinical Rejection (SCR) in kidney transplant recipients remains controversial. METHODS: We conducted a survey through UNOS across US transplant centers regarding their approach to surveillance biopsies and reasons for the non-performance of surveillance biopsies. RESULTS: Responses were obtained from 106/238 centers (45%) and only 18 (17%) of the centers performed surveillance biopsies on all patients and 22 (21%) performed biopsy for select cases...

Introducción: actualmente se considera que la acumulación de grasa corporal a nivel central se asocia con la presencia de hipertrigliceridemia, hipertensión arterial y diabetes. El índice de masa corporal (IMC) se ha utilizado para identificar la obesidad en la población general, pero no permite determinar la distribución de la grasa corporal, por lo que se pueden utilizar otras medidas antropométricas para evaluar la adiposidad y determinar su relación con la presencia de alteraciones metabólicas que presentan las personas con exceso de peso...

Obesity represents chronic inflammatory states promoted by pro-inflammatory M1-macrophage infiltration into white adipose tissue (WAT), thereby inducing insulin resistance. Herein, we demonstrate the importance of an ER stress protein, CHOP, in determining adipose tissue macrophage (ATM) polarity and systemic insulin sensitivity. A high-fat diet (HFD) enhances ER stress with CHOP upregulation in adipocytes. CHOP deficiency prevents HFD-induced insulin resistance and glucose intolerance with ATM M2 predomination and Th2 cytokine upregulation in WAT...
