AI Article Synopsis
- Muscarinic acetylcholine receptors were found on cultured astroblasts from embryonic chicken brains, indicated by specific binding of [3H]quinuclidinylbenzilate (QNB).
- The concentration of these receptors was measured at 76 fmol/mg protein.
- The binding affinity (Kd = 9.5 x 10(-11)) suggests a cooperative interaction among the receptors.
Article Abstract
Muscarinic acetylcholine receptors (76 fmol/mg protein) were detected on cultured glia cells (astroblasts) from embryonic chicken brain by specific [3H]quinuclidinylbenzilate (QNB) binding at physiological conditions. The QNB binding (Kd = 9.5 x 10(-11)) to the intact cells seems to be cooperative (nH = 1.98) as shown by graphical methods.

The role of rodent behavioral models of schizophrenia in the ongoing search for novel antipsychotics.
Expert Opin Drug Discov

Introduction: Existing pharmacotherapies for schizophrenia have not progressed beyond targeting dopamine and serotonin neurotransmission. Rodent models of schizophrenia are a necessary tool for elucidating neuropathological processes and testing potential pharmacotherapies, but positive preclinical results in rodent models often do not translate to positive results in the clinic.
Areas Covered: The authors reviewed PubMed for studies that applied rodent behavioral models of schizophrenia to assess the antipsychotic potential of several novel pharmacotherapies currently under investigation.

The increasing global elderly population, projected to reach 20% of individuals aged 65 and over by 2030, faces significant pulmonary challenges, including chronic obstructive pulmonary disease (COPD). Aging is associated with a natural decline in lung function and structural changes that exacerbate respiratory issues. COPD, characterized by chronic respiratory symptoms and airflow obstruction, presents a unique challenge in older patients due to the accelerated decline in lung function.

Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Imidacloprid, a widely used neonicotinoid insecticide, targets insect pests but also affects natural enemies. However, the effects of neonicotinoid insecticides on closely related insects remain unclear. We evaluated the harmful effects of imidacloprid on the phytophagous and predaceous .
