The alpha-2 adrenergic agonist guanfacine improves memory in aged monkeys without sedative or hypotensive side effects: evidence for alpha-2 receptor subtypes [PDF]

The Journal of Neuroscience, 1988
The present study attempted to identify an alpha-2 agonist that could improve working memory in aged nonhuman primates without the marked hypotensive and sedative side effects produced by clonidine. Toward this end, the hypotensive, sedative, and memory-altering properties of the alpha-2 adrenergic agonists, B-HT920 and guanfacine, were compared with ...

Beyond the Outburst: Charting a New Frontier for Understanding and Treating Irritability in Autistic Adults

Autism Research, EarlyView.
ABSTRACT Irritability is a prevalent and impairing feature associated with autism, yet remains poorly understood, particularly in adults. Drawing heavily on insights translated from pediatric and transdiagnostic literatures, we propose that irritability in autistic individuals often reflects a psychophysiological stress or threat response, rooted in a ...

"In vitro" study of the mode of action of antidepressants in cell culture models : comparison of the effects of "Hypericum perforatum L." extracts and classical synthetic compounds on the [beta]-adrenergic signal pathway [PDF]

, 2005
The clinical effectiveness of the plant extract of Hypericum perforatum L. in treating mild to moderate depression is well established. The extract shows a more favourable side effect profile than other antidepressant drugs, like tricyclics and selective

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

British Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Effects of dexmedetomidine and clonidine as propofol adjuvants on intra-operative hemodynamics and recovery profiles in patients undergoing laparoscopic cholecystectomy: A prospective randomized comparative study

Avicenna Journal of Medicine, 2015
Context: Alpha-2 (α2) adrenergic receptor agonists, clonidine and dexmedetomidine, are widely used as adjuvants during anesthesia for analgesic, sedative, sympatholytic, and cardiovascular stabilizing effects.

Bioluminescence Resonance Energy Transfer Reveals the Adrenocorticotropin (ACTH)-Induced Conformational Change of the Activated ACTH Receptor Complex in Living Cells

, 2011
Bioluminescence resonance energy transfer analysis is used to study the interaction between melanocortin 2 receptor (MC2R) accessory protein and the MC2R and provides evidence for protein kinase A-dependent conformational changes in the receptor complex ...

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Metabolic Dysfunction‐Associated Steatotic Liver Disease and Obesity: Pathogenesis, Diagnostics, Risk Stratification, and Therapeutic Approach

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as the most prevalent chronic liver disease worldwide, closely linked to the global rising incidence of obesity and metabolic syndrome. This review synthesizes current evidence on the pathogenesis, gut–liver axis, and multidisciplinary management of MASLD within the ...
