BACKGROUND: Venous thromboembolism (VTE) is associated with a high risk of recurrent events after withdrawal of anticoagulation. OBJECTIVES: The aim of this study was to determine the difference in plasma clot mechanical properties from patients having recurrent (r) versus non-recurrent (nr) VTE. METHODS: We previously developed a system for determining clot mechanical properties using an in-house magnetic tweezers system. This system was used to determine the mechanical properties of clots made from plasma of 11 patients with rVTE and 33 with nrVTE...

Esophageal adenocarcinoma (EAC) is a poor-prognosis cancer type with rapidly rising incidence. Understanding of the genetic events driving EAC development is limited, and there are few molecular biomarkers for prognostication or therapeutics. Using a cohort of 551 genomically characterized EACs with matched RNA sequencing data, we discovered 77 EAC driver genes and 21 noncoding driver elements. We identified a mean of 4.4 driver events per tumor, which were derived more commonly from mutations than copy number alterations, and compared the prevelence of these mutations to the exome-wide mutational excess calculated using non-synonymous to synonymous mutation ratios (dN/dS)...

Dental caries, erosion and hypersensitivity are major public health problems. SnF2 is used widely in oral care products to help prevent/treat these conditions. Casein phosphopeptide-stabilised amorphous calcium phosphate nanocomplexes (CPP-ACP) are a biomimetic nanotechnology of salivary phosphopeptide-ACP complexes that deliver bioavailable calcium and phosphate ions to promote dental remineralisation (repair). We show here using in vitro studies and a double-blind, randomised controlled, cross-over design in situ clinical trial that SnF2 and CPP-ACP interact to form a nanofilament coating on the tooth surface and that together they are superior in their ability to promote dental remineralisation...

#5
Jiabo Tan, Thomas H MacRae
The crustacean, Artemia franciscana, displays a complex life history in which embryos either arrest development and undertake diapause as cysts or they develop into swimming nauplii. Diapause entry is preceded during embryogenesis by the synthesis of specific molecular chaperones, namely the small heat shock proteins p26, ArHsp21, and ArHsp22, and the ferritin homolog, artemin. Maximal synthesis of diapause-specific molecular chaperones is dependent on the transcription factor, heat shock factor 1 (Hsf1), found in similar amounts in cysts and nauplii newly released from females...

BACKGROUND: Hospitals are looking for effective methods to track outcomes that are risk-adjusted for patient population characteristics. This is especially relevant for safety net hospitals (SNHs) servicing high-risk populations and in an era of quality-based reimbursement incentives. One such program with these goals is the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). This is an institution-based quality audit whereby we determined the presence and consistency of charted data required to compute perioperative risk in the ACS NSQIP risk calculator...

REVIEW
Kelvin Cheuk-Wai Leung, Jennifer Marie MacRae
In this review we discuss the evolving literature of anticoagulation in the context of the nephrology patient. Whereas CKD patients with atrial fibrillation, should be anticoagulated, the benefit of anticoagulation for those on dialysis remains controversial due to an increased risk of bleeding. The availability of direct oral anticoagulants offers new options for those with CKD. Until studies are available in stage 4 and 5/dialysis, this class of medication should be used with caution in this population. For anticoagulated patients requiring interventional procedures, a risk-based approach should be employed to determine those who will benefit from bridging anticoagulation...

Mangroves are ecosystems located in tropical and subtropical regions of the world and are vital for coastal protection. Their unique characteristics make them hotspots for carbon cycling and biological diversity. Studies on isolated filamentous fungi and environmental and anthropogenic factors that influence sediments offer new understandings on how to preserve mangroves. Here we report on the filamentous fungi isolated from four mangroves. We correlated fungal community composition with sediment texture, polycyclic aromatic hydrocarbons concentration (oil pollution), pH, salinity, organic matter, total and thermotolerant coliforms (sewage pollution)...

Obesity increases the risk for cardiometabolic diseases. N-acyl phosphatidylethanolamines (NAPEs) are precursors of N-acylethanolamides, which are endogenous lipid satiety factors. Incorporating engineered bacteria expressing NAPEs into the gut microbiota retards development of diet induced obesity in wild-type mice. Because NAPEs can also exert anti-inflammatory effects, we hypothesized that administering NAPE-expressing bacteria to low-density lipoprotein receptor (Ldlr)-/- mice fed a Western diet would improve various indices of cardiometabolic disease manifested by these mice...

The AXIN2 gene, like APC, plays a role in the Wnt signalling pathway involved in colorectal tumour formation. Heterozygous mutations in AXIN2 have been shown to cause ectodermal dysplasia (including tooth agenesis, or more specifically, oligodontia), and, in some carriers, colorectal cancer and/or adenomatous polyposis develops. There is a paucity of published AXIN2 families making genotype-phenotype (polyposis, colorectal cancer and oligodontia) correlations challenging. In this case report we describe a family with c...

BACKGROUND: Knee kinematics when running, specifically knee valgus, have been linked to patellofemoral pain syndrome. Assessing running biomechanics requires skill, equipment and time. Clinically, the single leg squat is used to make inferences about knee kinematics during running. No evidence supports this practice. METHODS: Sixteen asymptomatic runners and sixteen runners with patellofemoral pain syndrome were recruited. Asymptomatic runners were sub-divided by dominant and non-dominant leg and runners with patellofemoral pain syndrome by painful and non-painful leg...

Embryos of the crustacean, Artemia franciscana may arrest as gastrulae, forming cysts that enter diapause, a state of reduced metabolism and enhanced stress tolerance. Diapausing cysts survive physiological stresses for years, due in part to molecular chaperones. p26, a small heat shock protein, is an abundant diapause-specific molecular chaperone in cysts and it affects embryo development and stress tolerance. p26 is therefore thought to influence many proteins in cysts and this study was undertaken to determine how the loss of p26 by RNA interference (RNAi) affects the diapause proteome of A...

BACKGROUND: In the UK, patients with one or two adenomas, of which at least one is ≥ 10 mm in size, or three or four small adenomas, are deemed to be at intermediate risk of colorectal cancer (CRC) and referred for surveillance colonoscopy 3 years post polypectomy. However, colonoscopy is costly, can cause discomfort and carries a small risk of complications. OBJECTIVES: To determine whether or not annual faecal immunochemical tests (FITs) are effective, acceptable and cost saving compared with colonoscopy surveillance for detecting CRC and advanced adenomas (AAs)...

Active transport of microRNAs (miRNA) in extracellular vesicles (EV) occurs in disease. Circulating EV-packaged miRNAs in the serum of stroke patients were compared to stroke mimics with matched cardio- and cerebrovascular risk factors, with corroboration of results in a pre-clinical model. An unbiased miRNA microarray was performed in stroke vs. stroke mimic patients (n = 39). Results were validated (n = 173 patients) by real-time quantitative polymerase chain reaction. miRNA expression was quantified in total serum/EV (n = 5-7) of naïve adult spontaneously hypertensive stroke-prone rats (SHRSP), their normotensive reference strain (Wistar Kyoto, WKY) and in circulating EV (n = 3), peri-infarct brain (n = 6), or EV derived from this region (n = 3) in SHRSP following transient middle cerebral artery occlusion (tMCAO)...

RATIONALE: Atherosclerosis is in part caused by immune and inflammatory cell infiltration into the vascular wall, leading to enhanced inflammation and lipid accumulation in the aortic endothelium. Understanding the molecular mechanisms underlying this disease is critical for the development of new therapies. Our recent studies demonstrate that epsins, a family of ubiquitin-binding endocytic adaptors, are critical regulators of atherogenicity. Given the fundamental contribution lesion macrophages make to fuel atherosclerosis, whether and how myeloid specific epsins promote atherogenesis is an open and significant question...
