Melatonin protects against focal cerebral ischemia-reperfusion injury in diabetic mice by ameliorating mitochondrial impairments: involvement of the Akt-SIRT3-SOD2 signaling pathway.

Aging (Albany NY) 2021 Jun 11;13. Epub 2021 Jun 11.

Department of Anesthesiology, Renmin Hospital of Wuhan University, Wuhan, Hubei 430060, China.

Diabetic patients are more vulnerable to cerebral ischemia-reperfusion (CIR) injury and have a worse prognosis and higher mortality after ischemic stroke than non-diabetic counterparts. Melatonin can exert neuroprotective effects against CIR injury in nondiabetic animal models. However, its effects on diabetic CIR injury and the underlying mechanisms remain unclarified. Read More

Feasibility and acceptability of mindful recovery opioid use care continuum (M-ROCC): A concurrent mixed methods study.

J Subst Abuse Treat 2021 Apr 15;130:108415. Epub 2021 Apr 15.

Harvard Medical School, Boston, MA, United States of America; Cambridge Health Alliance, Cambridge, MA, United States of America; Geisel School of Medicine at Dartmouth College, Hanover, NH, United States of America. Electronic address:

As opioid overdose deaths increase, buprenorphine/naloxone (B/N) treatment is expanding, yet almost half of patients are not retained in B/N treatment. Mindfulness-based interventions (MBIs) designed to promote non-judgmental awareness of present moment experience may be complementary to B/N treatment and offer the potential to enhance retention by reducing substance use and addressing comorbid symptoms. In this pilot study, we examined the feasibility and acceptability of the Mindful Recovery OUD Care Continuum (M-ROCC), a trauma-informed, motivationally sensitive, 24-week MBI. Read More

Acute experimental barrier injury triggers ulcerative colitis specific innate hyper-responsiveness and ulcerative colitis-type microbiome changes in humans.

Cell Mol Gastroenterol Hepatol 2021 Jun 9. Epub 2021 Jun 9.

Department of Gastroenterology, Herlev Hospital, University of Copenhagen, Denmark.

Background And Aims: The trigger hypothesis opens the possibility of anti-flare-initiation therapies by stating that ulcerative colitis (UC) flares originates from inadequate responses to acute mucosal injuries. However, experimental evidence is restricted by a limited use of suitable human models. We thus aimed to investigate the acute mucosal barrier injury responses in humans with and without UC using an experimental injury model. Read More

K channel blockers control glucagon secretion by distinct mechanisms: a direct stimulation of α-cells involving a [Ca] rise and an indirect inhibition mediated by somatostatin.

Mol Metab 2021 Jun 9:101268. Epub 2021 Jun 9.

Université Catholique de Louvain, Institut de Recherche Expérimentale et Clinique, Pôle d'Endocrinologie, Diabète et Nutrition, Brussels, Belgium. Electronic address:

Objective: Glucagon is secreted by pancreatic α-cells in response to hypoglycemia and its hyperglycemic effect helps to restore normal blood glucose. Insulin and somatostatin (SST) secretions from β- and δ-cells, respectively, are stimulated by glucose by mechanisms implicating an inhibition of their ATP-sensitive K (K) channels, leading to an increase in [Ca] that triggers exocytosis. Drugs that close K channels, such as sulfonylureas, are used to stimulate insulin release in type 2 diabetic patients. Read More

Autoimmun Rev 2021 Jun 9:102865. Epub 2021 Jun 9.

Department of Medicine C, Wolfson Medical Center, Holon, Israel; Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Background And Aims: The novel SARS-CoV-2 has been rattling the world since its outbreak in December 2019, leading to the COVID-19 pandemic. The learning curve of this new virus has been steep, with a global scientific community desperate to learn how the virus is transmitted, how it replicates, what cause such a wide spectrum of disease manifestations, causing none or few symptoms in some. Others are burdened by an intense immune response that resembles the cytokine storm syndrome (CSS), which leads to severe disease manifestations, often complicated by fatal acute respiratory distress syndrome and death.

Short Stay After Shoulder Arthroplasty Does Not Increase 90-Day Readmissions in Medicare Patients Compared to Privately-Insured Patients.

J Shoulder Elbow Surg 2021 Jun 9. Epub 2021 Jun 9.

Department of Orthopaedic Surgery, Duke University Medical Center, Durham, NC 27710, USA.

Background: As of January 1, 2021 total shoulder arthroplasty was removed from the Medicare inpatient-only list, reflecting a growing belief in the potential merits of same-day discharge regardless of insurance type. It is yet unknown whether Medicare populations, who frequently have more severe comorbidity burdens, would experience higher complication rates relative to privately-insured patients who are often younger with fewer comorbidities. Given the limited number of true outpatient cohorts available to study, discharge at least by postoperative day 1 may serve as a useful proxy for true same-day discharge, and we hypothesized that these Medicare patients would have increased 90-day readmission rates compared to their privately-insured counterparts.

Biglycan in hepatorenal crosstalk Biglycan: a regulator of hepatorenal inflammation and autophagy.

Matrix Biol 2021 Jun 9. Epub 2021 Jun 9.

Institute of Pharmacology and Toxicology, Goethe University, Frankfurt, Germany. Electronic address:

Soluble biglycan, a small leucine-rich proteoglycan, plays a significant role in several pathologies as it has emerged as an extracellular matrix-derived danger-associated molecular pattern. Biglycan is released from the extracellular matrix in response to tissue injury and, as a canonical danger signal, interacts with innate immune receptor, Toll-like receptors 2 and 4, thereby triggering a sustained inflammatory response. Recent evidence indicates that biglycan acts as a molecular switch between inflammation and autophagy by a specific interaction with the Toll-like co-receptor CD14 and CD44, respectively. Read More
