The Biological Significance of von Willebrand Factor O-Linked Glycosylation.

Semin Thromb Hemost 2021 Jun 15. Epub 2021 Jun 15.

Haemostasis Research Group, Irish Centre for Vascular Biology, School of Pharmacy and Bimolecular Sciences, Royal College of Surgeons in Ireland, Dublin, Ireland.

Glycosylation is a key posttranslational modification, known to occur on more than half of all secreted proteins in man. As such, the role of N- and O-linked glycan structures in modulating various aspects of protein biology is an area of much research. Given their prevalence, it is perhaps unsurprising that variations in glycan structures have been demonstrated to play critical roles in modulating protein function and have been implicated in the pathophysiology of human diseases.

Anti-Xa Monitoring of Low-Molecular-Weight Heparin during Pregnancy: A Systematic Review.

Semin Thromb Hemost 2021 Jun 15. Epub 2021 Jun 15.

Department of Clinical Biochemistry, Aarhus University Hospital, Aarhus, Denmark.

Low-molecular-weight heparin (LMWH) is commonly used for preventing or treating venous thromboembolic disease (VTE) during pregnancy. The physiological changes in maternal metabolism have led to discussions on optimal LMWH dosing strategy and possible need for monitoring. The aim of this systematic review is to summarize and discuss whether LMWH dose adjustment according to anti-Xa provides superior effectiveness and safety compared with weight adjusted or fixed dosed LMWH in pregnant women.

MrgprdCre lineage neurons mediate optogenetic allodynia through an emergent polysynaptic circuit.

Pain 2021 Jul;162(7):2120-2131

Department of Neurobiology, University of Pittsburgh, Pittsburgh, PA, United States.

Abstract: Most cutaneous C fibers, including both peptidergic and nonpeptidergic subtypes, are presumed to be nociceptors and respond to noxious input in a graded manner. However, mechanically sensitive, nonpeptidergic C fibers also respond to mechanical input in the innocuous range, so the degree to which they contribute to nociception remains unclear. To address this gap, we investigated the function of nonpeptidergic afferents using the MrgprdCre allele. Read More

Long-Term Outcomes of Kidney Transplants from Older/Marginal Donors: A Cohort Study.

Nephron 2021 Jun 15:1-11. Epub 2021 Jun 15.

Istituto di Ricerche Farmacologiche Mario Negri IRCCS, Bergamo, Italy.

Introduction: To safely expand the donor pool, we introduced a strategy of biopsy-guided selection and allocation to single or dual transplantation of kidneys from donors >60 years old or with hypertension, diabetes, and/or proteinuria (older/marginal donors). Here, we evaluated the long-term performance of this approach in everyday clinical practice.

Methods: In this single-center cohort study, we compared outcomes of 98 patients who received one or two biopsy-evaluated grafts from older/marginal donors ("recipients") and 198 patients who received nonhistologically assessed single graft from ideal donors ("reference-recipients") from October 2004 to December 2015 at the Bergamo Transplant Center (Italy).

A rise in Proteobacteria is an indicator of gut-liver axis-mediated nonalcoholic fatty liver disease in high-fructose-fed adult mice.

Nutr Res 2021 May 21;91:26-35. Epub 2021 May 21.

Laboratory of Morphometry, Metabolism, and Cardiovascular Diseases, Biomedical Center, Institute of Biology, Rio de Janeiro State University, Rio de Janeiro, Brazil. Electronic address:

Current evidence suggests that high fructose intake results in gut dysbiosis, leading to endotoxemia and NAFLD onset. Thus, the hypothesis of the study was that an enhanced Proteobacteria proportion in the cecal microbiota could be the most prominent trigger of NAFLD through enhanced endotoxin (LPS) in adult high-fructose-fed C57BL/6 mice. Male C57BL/6 mice received a control diet (n = 10, C: 76% of energy as carbohydrates, 0% as fructose) or high-fructose diet (n = 10, HFRU: 76% of energy as carbohydrate, 50% as fructose) for 12 weeks.
