RAD51, a key factor in homology-directed repair (HDR), has long been considered an attractive target for cancer therapy, but few specific inhibitors have been found. A cell-penetrating, anti-DNA, lupus autoantibody, 3E10, was previously shown to inhibit HDR, sensitize tumors to radiation, and mediate synthetic lethal killing of BRCA2-deficient cancer cells, effects that were initially attributed to its affinity for DNA. However, as the molecular basis for its ability to inhibit DNA repair, we report that 3E10 directly binds to the N-terminus of RAD51, sequesters RAD51 in the cytoplasm, and impedes RAD51 binding to DNA...

OBJECTIVE: Oral Anticoagulation Treatment (OAT) resumption is a therapeutic dilemma in Intracerebral Hemorrhage (ICH) care, particularly for lobar hemorrhages related to amyloid angiopathy. We sought to determine whether OAT resumption after ICH is associated with long-term outcome, accounting for ICH location (i.e. lobar vs. non-lobar). METHODS: We meta-analyzed individual patient data from: 1) the multi-center RETRACE study (n=542); 2) a US-based single-center ICH study (n=261); 3) the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study (n=209)...

Acute graft-versus-host disease (aGVHD) is a major complication of allogeneic haematopoietic stem cell transplantation (HSCT). With new promising therapies, survival may improve for severe aGVHD. We wanted to analyze the long-term outcome in patients who survive severe aGVHD. This study was a landmark analysis of 23,567 patients with acute Leukaemia who survived for more than 6 months after HSCT, 2002-2014. Patients alive after severe aGVHD (n = 1,738) were compared to controls. Patients with severe aGVHD had higher non-relapse mortality (NRM) and higher rate of extensive chronic GVHD (cGVHD) than the controls (p < 10(-5) )...

Background & Aims: Heavy alcohol use can lead to progressive liver damage, especially in individuals with chronic hepatitis C (HCV), however the impact of non-heavy use is not clear. We studied long-term effects of modest alcohol use on fibrosis progression in a large cohort of women co-infected with HIV/HCV. Methods: Alcohol intake was ascertained every 6 months and use categorized as abstinent, light (1-3 drinks/week), moderate (4-7 drinks/week), heavy (>7 drinks/week) and very heavy (>14 drinks/week)...

BACKGROUND: We aimed to characterize variability in cost after straightforward orthotopic liver transplant (OLT). METHODS: Using the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases, we identified patients who underwent OLT between 2011 and 2014. Patients meeting criteria for straightforward OLT, defined as length of stay < 14 days with discharge to home, were selected (n = 5763) and grouped into tertiles (low, medium, high) according to cost of perioperative stay...

We report the characterization of a novel class of lipid mediators termed elovanoids (ELVs) (ELV-N32 and ELV-N34), which are dihydroxylated derivatives of 32:6n3 and 34:6n3, respectively. The precursors of ELVs are made by elongation of a 22:6n3 fatty acid and catalyzed by ELOVL4 (elongation of very-long-chain fatty acids-4). The structure and stereochemistry of ELVs were established using synthetic compounds produced by stereocontrolled total synthesis. We report that ELV-mediated protection is induced in neuronal cultures undergoing either oxygen/glucose deprivation or N-methyl-d-aspartate receptor-mediated excitotoxicity, as well as in experimental ischemic stroke...

While numerous surveys highlighted the natural co-occurrence of mycotoxins in food, data about their toxicological combined effects is still limited. This is especially the case for chronic exposure conditions, although the latter are more representative of the mycotoxin risk associated with food consumption than acute exposure. In the present study, cell viability and gene expression levels of relevant hepatocyte-specific functions were evaluated for the HepaRG human liver cell line exposed to deoxynivalenol (DON) and/or zearalenone (ZEA) during 14, 28 and 42days at three subtoxic concentrations corresponding to i) the determined average exposure dose of French adult population, ii) the tolerable daily intake established by the Joint FAO/WHO Expert Committee and iii) the maximum level permitted by the European regulation in cereals intended for direct human consumption...

REVIEW
Audrey J Gaskins, Jorge E Chavarro
The literature on the relationship between diet and human fertility has greatly expanded over the last decade, resulting in the identification of a few clear patterns. Intake of supplemental folic acid, particularly at doses higher than those recommended for the prevention of neural tube defects, has been consistently related to lower frequency of infertility, lower risk of pregnancy loss, and greater success in infertility treatment. On the other hand and despite promising evidence from animal models, vitamin D does not appear to exert an important role in human fertility in the absence of deficiency...

PURPOSE: Defining biochemical failure as nadir+2 may overestimate cure after radiotherapy. We assess long term PSA stability after low dose rate prostate brachytherapy and predictors of biochemical failure when the PSA is slowly rising below the nadir + 2 ng/ml threshold. METHODS AND MATERIALS: From 1998-2010, 2339 low/ intermediate risk prostate cancers had Iodine-125 brachytherapy with a minimum 3 year follow. 49.7% had 6 months' androgen deprivation. Clinical, dosimetric and PSA data were retrieved from a prospective database...

In lymph nodes (LNs), dendritic cells (DCs) are thought to dispose of apoptotic cells, a function pertaining to macrophages in other tissues. We found that a population of CX3CR1(+) MERTK(+) cells located in the T cell zone of LNs, previously identified as DCs, are efferocytic macrophages. Lineage-tracing experiments and shield chimeras indicated that these T zone macrophages (TZM) are long-lived macrophages seeded in utero and slowly replaced by blood monocytes after birth. Imaging the LNs of mice in which TZM and DCs express different fluorescent proteins revealed that TZM-and not DCs-act as the only professional scavengers, clearing apoptotic cells in the LN T cell zone in a CX3CR1-dependent manner...

BACKGROUND AND PURPOSE: Arterial spin labeling (ASL) MRI is a promising, noninvasive technique to image cerebral blood flow (CBF) but is difficult to use in cerebrovascular patients with abnormal, long arterial transit times through collateral pathways. To be clinically adopted, ASL must first be optimized and validated against a reference standard in these challenging patient cases. METHODS: We compared standard-delay ASL (post-label delay=2.025 seconds), multidelay ASL (post-label delay=0...

Encapsulation of human embryonic stem-cell-differentiated beta cell clusters (hES-βC) holds great promise for cell replacement therapy for the treatment of diabetics without the need for chronic systemic immune suppression. Here, we demonstrate a nanoporous immunoprotective polymer thin film cell encapsulation device that can exclude immune molecules while allowing exchange of oxygen and nutrients necessary for in vitro and in vivo stem cell viability and function. Biocompatibility studies show the device promotes neovascular formation with limited foreign body response in vivo...

BACKGROUND: Plasma angiopoietin-like 2 (Angptl2), a proinflammatory protein, has been associated with obesity and diabetes. Whether weight loss induced by bariatric surgery and associated improvement of the cardiometabolic risk profile influence circulating Angptl2 levels is unknown. We tested whether biliopancreatic diversion with duodenal switch (BPD-DS) surgery alters plasma Angptl2 concentrations. METHODS: Severely obese patients (n = 73; body mass index: 49...

Metabolic markers associated with the Metabolic Syndrome (MetS) may be affected by interactions between the APOE genotype and plasma fatty acids (FA). In this study, we explored FA-gene interactions between the missense APOE polymorphisms and FA status on metabolic markers in MetS. Plasma FA, blood pressure, insulin sensitivity and lipid concentrations were determined at baseline and following a 12-week randomized, controlled, parallel, dietary FA intervention in 442 adults with MetS (LIPGENE study). FA-APOE gene interactions at baseline and following change in plasma FA were assessed using adjusted general linear models...

A diet containing a high n-3/n-6 polyunsaturated fatty acids (PUFA) ratio has cardioprotective properties. PUFAs incorporation into membranes influences the function of membrane proteins. We investigated the impact of the membrane incorporation of PUFAs, especially eicosapentaenoic acid (EPA) (C20:5 n-3), on the anti-atherogenic cholesterol efflux pathways. We used cholesteryl esters (CE)-loaded human monocyte-derived macrophages (HMDM) to mimic foam cells exposed to the FAs for a long period of time to ensure their incorporation into cellular membranes...

BACKGROUND: In the short-term, laparoscopic sleeve gastrectomy has been shown to be effective for the treatment of the type 2 diabetes in patients with severe obesity. There are few data with greater follow-up. Our aim was to evaluate the results of laparoscopic sleeve gastrectomy on the control of type 2 diabetes in patients with severe obesity at 5 years at the University Hospital, France. METHODS: From a total of 355 patients with severe obesity operated between January 2006 and June 2010, 52 (15%) had a diagnosis of type 2 diabetes before undergoing laparoscopic sleeve gastrectomy...

Archaeal swimming motility is driven by archaella: rotary motors attached to long extracellular filaments. The structure of these motors, and particularly how they are anchored in the absence of a peptidoglycan cell wall, is unknown. Here, we use electron cryotomography to visualize the archaellar basal body in vivo in Thermococcus kodakaraensis KOD1. Compared to the homologous bacterial type IV pilus (T4P), we observe structural similarities as well as several unique features. While the position of the cytoplasmic ATPase appears conserved, it is not braced by linkages that extend upward through the cell envelope as in the T4P, but rather by cytoplasmic components that attach it to a large conical frustum up to 500 nm in diameter at its base...
