Am J Physiol Regul Integr Comp Physiol 2021 Sep 15. Epub 2021 Sep 15.

Department of Physiology, grid.279863.1Louisiana State University Health Sciences Center New Orleans, New Orleans, Louisiana, United States.

Objective: Aging people living with HIV (PLWH), especially post-menopausal women may be at higher risk of comorbidities associated with HIV, ART, hypogonadism and at-risk alcohol use. Our studies in simian immunodeficiency virus (SIV)-infected male macaques demonstrated that chronic binge alcohol (CBA) reduced acute insulin response to glucose (AIRG), and at-risk alcohol use decreased HOMA-β in PLWH. The objective of this study was to examine the impact of ovariectomy (OVX), on glucose-insulin dynamics and integrity of pancreatic endocrine function in CBA/SIV-infected female macaques. Read More

The Effects of Intermittent Hypoxic-Hyperoxic Exposures on Lipid Profile and Inflammation in Patients With Metabolic Syndrome.

Front Cardiovasc Med 2021 27;8:700826. Epub 2021 Aug 27.

Department of Cardiology, Functional and Ultrasound Diagnostics, N.V. Sklifosofsky, I. M. Sechenov First Moscow State Medical University, Moscow, Russia.

Patients with metabolic syndrome (MS) tend to suffer from comorbidities, and are often simultaneously affected by obesity, dysglycemia, hypertension, and dyslipidemia. This syndrome can be reversed if it is timely diagnosed and treated with a combination of risk factors-reducing lifestyle changes and a tailored pharmacological plan. Interval hypoxic-hyperoxic training (IHHT) has been shown as an effective program in reducing cardiovascular risk factors in patients with MS even in the absence of exercise. Read More

Microglial Activation of GLP-1R Signaling in Neuropathic Pain Promotes Gene Expression Adaption Involved in Inflammatory Responses.

Neural Plast 2021 31;2021:9923537. Epub 2021 Aug 31.

Shanghai Key Laboratory of Psychotic Disorders, Shanghai Mental Health Center, Shanghai Jiao Tong University, School of Medicine, School of Pharmacy, Shanghai 200240, China.

Background: Neuropathic pain is a common chronic pain, which is related to hypersensitivity to stimulus and greatly affects the quality of life of patients. Maladaptive gene changes and molecular signaling underlie the sensitization of nociceptive pathways. We previously found that the activation of microglial glucagon-like peptide 1 receptor (GLP-1R) could potently relieve formalin-, bone cancer-, peripheral nerve injury-, and diabetes-induced pain hypersensitivity.

Modulating the Activity of the VMPFC With tDCS Alters the Social Framing Effect.

Front Behav Neurosci 2021 26;15:677006. Epub 2021 Aug 26.

Center for Economic Behavior and Decision-Making, Zhejiang University of Finance and Economics, Hangzhou, China.

Numerous experimental studies have replicated the social framing effect-the observation that people's decisions related to economic benefits and feelings depend on the method of presentation. Previous neuroimaging studies have shown that the ventromedial prefrontal cortex (VMPFC) plays a part in the influence of framing and how individuals think about the feelings of others. Based on this, we used transcranial direct current stimulation (tDCS) to modulate neuronal activity in the VMPFC to determine the likelihood of a direct association between VMPFC activity and the social framing effect.

Technical Note: Modulation of fMRI brainstem responses by transcutaneous vagus nerve stimulation.

Neuroimage 2021 Sep 10;244:118566. Epub 2021 Sep 10.

Translational Neurocircuitry Group, Max Planck Institute for Metabolism Research, Gleueler Strasse 50, 50931, Cologne, Germany; Cluster of Excellence in Cellular Stress Responses in Aging Associated Diseases (CECAD), University of Cologne, 50931, Cologne, Germany.

Our increasing knowledge about gut-brain interaction is revolutionising the understanding of the links between digestion, mood, health, and even decision making in our everyday lives. In support of this interaction, the vagus nerve is a crucial pathway transmitting diverse gut-derived signals to the brain to monitor of metabolic status, digestive processes, or immune control to adapt behavioural and autonomic responses. Hence, neuromodulation methods targeting the vagus nerve are currently explored as a treatment option in a number of clinical disorders, including diabetes, chronic pain, and depression. Read More
