Assessment of Effects of α2-Adrenoceptor Agonists and Antagonists in Dorsal Hippocampus on Muscimol State-dependent Memory

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2014
Background and Objectives: Adrenergic and GABAergic systems of the brain play an important role in memory and learning. According to results of studies, morphine, histamine, and lithium induce state-dependent learning.

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score

ESC Heart Failure, Volume 12, Issue 2, Page 1427-1436, April 2025.
Abstract Background and objectives Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis.

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.

Microvascular Abnormalities in Adolescents With Anorexia Nervosa: Nailfold Video Capillaroscopic Evidence at Acute and Remission States

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Chronic malnutrition, hypothermia, and hormonal imbalance in anorexia nervosa (AN) may impair capillary structure and perfusion. This study aimed to describe the nailfold videocapillaroscopy (NVC) findings in adolescents with AN and atypical AN (AAN), to assess their association with Raynaud's phenomenon (RP), and evaluate ...

Progress in the Role of Mast Cells and Biomolecular Signals in the Mechanism of Postoperative Ileus: From Cellular Activation to Exploration of the Brain–Gut Axis

Gut Medicine, EarlyView.
ABSTRACT Postoperative ileus (POI) is a frequent complication after surgical procedures, predominantly manifesting as aberrant gastrointestinal motility, which markedly extends the duration of postoperative recovery for patients. The clinical duration of POI is typically modulated by intricate inflammatory cascades, with mast cells assuming a critical ...

Imipramine Increases Norepinephrine and Serotonin in the Salivary Glands of Rats

Biology
Xerostomia induced by antidepressants such as imipramine has long been thought to be due to their anticholinergic effects. However, even antidepressants with low anticholinergic effects may have a high incidence of xerostomia.

Increased alpha 2-adrenergic binding sites and antilipolytic effect in adipocytes from genetically obese rats.

Journal of Lipid Research, 1990
We have recently shown that functional alpha 2-adrenergic receptors, assessed by the alpha 2-agonist UK 14304, are present in rat white fat cells as in adipocytes of humans and other species.
