The Different Effects of Noradrenaline on Rhabdomyosarcoma and Ewing’s Sarcoma Cancer Hallmarks—Implications for Exercise Oncology

open access: yesOnco
Background: Exercise has beneficial effects on cancer and its treatment, but the underlying mechanisms are poorly understood. Some studies have linked the positive impact of exercise to catecholamine signaling.

Pregnancy modifies the α2-β-adrenergic receptor functional balance in rabbit fat cells

open access: yesJournal of Lipid Research, 1999
The sympathetic nervous system controls lipolysis in fat by activation of four adrenergic receptors: β1, β2, β3, and α2. During pregnancy, maternal metabolism presents anabolic and catabolic phases, characterized by modifications of fat responsiveness to

Glucose Intolerance on Phaeochromocytoma and Paraganglioma—The Current Understanding and Clinical Perspectives

open access: yesFrontiers in Endocrinology, 2020
Half of the patients with phaeochromocytoma have glucose intolerance which could be life-threatening as well as causing postoperative hypoglycemia. Glucose intolerance is due to impaired insulin secretion and/or increased insulin resistance.

Molecular Mechanism for Ligand Recognition and Subtype Selectivity of α2C Adrenergic Receptor

open access: yesCell Reports, 2019
Summary: Adrenergic G-protein-coupled receptors (GPCRs) mediate different cellular signaling pathways in the presence of endogenous catecholamines and play important roles in both physiological and pathological conditions.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

open access: yesAnimal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

The Association Between Maternal Asthma and Child Autism: A Systematic Review and Meta‐Analysis

open access: yesAutism Research, EarlyView.
ABSTRACT Maternal asthma has been linked to child autism. In this study, we systematically reviewed observational studies published between July 2001 and February 2024 that assessed maternal asthma during pregnancy (exposure) and child autism (outcome). Databases searched included MEDLINE, CINAHL, EMBASE, and PsycINFO.

Beyond right or wrong: How partial credit scoring on multiple‐choice questions improves student performance and assessment perceptions

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims In this study, we examined the effects of assigning partial credit to selected answer choices on student performance and perceptions in a pharmacology course using Type A multiple‐choice questions (MCQs). Methods Partial credit scoring was incorporated into quizzes and exams in a 10‐week pharmacology course for postbaccalaureate premedical ...
