33 mU/107 cfu) as well. We anticipate that this strain can be innovatively applied to the valorization of marine crustaceans side streams.Alginate oligosaccharide (AOS) was reported to possess antioxidant and free radical scavenging activities, but the specific effects and mechanisms remain unclear. We investigated the effects of AOS on H2O2-induced oxidative stress and apoptosis in human umbilical vein endothelial cells (HUVECs) and the associated mechanisms. HUVECs were treated with 100-800 µM hydrogen peroxide (H2O2) for various periods (12, 24, and 36 h) to establish an in vitro oxidative stress and apoptosis HUVEC model. AOS protects HUVEC cells against oxidative stress-induced apoptosis by decreasing the expression levels of caspase 3 and Bax, and increasing Bcl-2 expression. Microarray assay, real-time PCR and western blot results revealed that AOS was able to effectively suppress H2O2-induced apoptosis via regulated integrin-α/FAK/PI3K pathway by influencing the expression of integrin-α, FAK, PI3K, PTEN, P21, and CDK2. In conclusion, our study suggests that AOS can protect endothelial cells against oxidative stress injury caused by H2O2, providing novel alternative strategies to prevent atherosclerosis in the future.This prospective cohort study evaluates associations between structural and ultrastructural parameters in baseline biopsies from human kidney transplants and long-term graft survival after more than 14 years' follow-up. Baseline kidney graft biopsies were obtained prospectively from 54 consecutive patients receiving a kidney transplant at a single institution. Quantitative measurements were performed on the baseline biopsies by computer-assisted light microscopy and electron microscopy. Stereology-based techniques estimated the fraction of interstitial tissue, the volume of glomeruli, mesangial fraction, and basement membrane thickness of glomerular capillaries. The fraction of occluded glomeruli and scores according to the Banff classification were achieved. Kidney graft survival was analyzed by Kaplan-Meier estimates and Cox regression. Association to long-term kidney function was also analyzed. The long-term surviving kidney transplants were characterized at implantation by less arteriolar hyaline thickening (P less then 0.001) and less interstitial fibrosis (P = 0.001), as well as a lower fraction of occluded glomeruli (P = 0.004) and lower glomerular volume (P = 0.03). At the latest follow-up, eGFR was decreased by 12 ml/min/1.73 m2 per unit increase in the score for arteriolar hyalinosis at implantation (P = 0.02), and eGFR was decreased by 19 ml/min/1.73 m2 per 106 μm3 increase in glomerular volume at baseline (P = 0.03). The unbiased Cavalieri estimate of glomerular volume and the ultrastructural parameters are the first to be evaluated in a cohort study with prospective follow-up for more than 14 years. The study shows that baseline biopsies from human kidney grafts contain extraordinary long-term prognostic information, and it highlights the importance of these intrinsic graft factors.
Optimal stroke prevention strategies for patients with atrial fibrillation (AF) who experience a major bleed are poorly defined. We sought to estimate the effectiveness and safety of oral anticoagulation (OAC) represcription after an OAC contraindication.

TREAT-AF is a retrospective cohort study of patients with newly diagnosed AF (2004-2012), treated in the Veterans Health Administration. From this cohort, we identified patients with a contraindication to OAC after AF diagnoses, defined as incident intracranial bleeding, non-intracranial bleeding requiring hospitalization, or unrepaired cerebral aneurysm or aortic dissection. We used multivariate Cox proportional hazards to estimate the association of OAC prescription in the 90days following OAC contraindication to ischemic stroke and rebleeding.

Among 167,190 patients with newly diagnosed AF (70 ± 11years, 1.7% female, CHA
DS
-VASc 2.7 ± 1.7), 19,285 patients (11.5%) had an incident bleed (n = 18,342) or an unrepaired cerebral aneurysm or aortic disevention approaches after major bleeding events could be beneficial if bleeding risk can be successfully mitigated.
Data on antithrombotic therapy after percutaneous left atrial appendage occlusion (LAAO) is scarce and no randomized evaluation has been performed to demonstrate what is the best antithrombotic strategy. Up to date, different antithrombotic regimens with variable durations are currently used. In fact, the use of oral anticoagulation (OAC) or dual antiplatelet therapy (DAPT) with aspirin and clopidogrel during the initial phase (∓ 3months post-LAAO) has been proposed as valid strategies. However, antiplatelet and OAC therapies have never been compared in a randomized study after left atrial appendage closure (LAAC). The purpose of the present study is to ascertain an optimal antithrombotic strategy after LAAC in terms of safety and efficacy. The study will compare a novel OAC (NOAC) with a highly safety profile like apixaban 5mg/12h or 2.5mg/12h (after dose adjustment or in high-risk patients) with standard antiplatelet therapy with DAPT. The aim of the study was tocompare a strategy of anticoagulation with apixaban 5mg/2.5mg bid to the current standard of care (DAPT with aspirin and clopidogrel) after LAAO in patients with non-valvular atrial fibrillation (AF).

This is a phase IV multicenter randomized, open-label, controlled trial comparing the efficacy and safety of apixaban vs. DAPT after LAAO, both for 3months. The primary endpoint is a combined endpoint of death, myocardial infarction, stroke, thromboembolic complications, and major or significant bleeding at 3months of follow-up. Approximately 160 subjects will be enrolled and followed 12months from randomization.

Considering the high risk of both thromboembolic and hemorrhagic events of patients undergoing LAAO, establishment of an appropriate antithrombotic therapy in terms of efficacy and safety after LAAO is of vital importance.

To evaluate the associations between computed tomography (CT) imaging features extracted from the structured American Pancreatic Association (APA)/Society of Abdominal Radiology (SAR) template and overall survival in patients with resected pancreatic ductal adenocarcinoma (PDAC).

This retrospective analysis included consecutive patients with PDAC who consented to genomic tumor testing and underwent preoperative imaging and curative intent surgical resection from December 2006 to July 2017. Two radiologists assessed preoperative CT imaging using the APA/SAR PDAC-reporting template. buy Disodium Phosphate Univariable associations between overall survival and imaging variables were evaluated using Cox proportional hazards regression.

The study included 168 patients (66years ± 11; 91 women). 126/168 patients (75%) received upfront surgical resection whereas 42/168 (25%) received neoadjuvant therapy prior to surgical resection. In the entire cohort, features associated with decreased overall survival were tumor arterial contact of any kind (hazard ratio (HR) 1.
