Icahn School of Medicine at Mount Sinai, New York, NY, USA.
Background: The Accelerating Medicines Partnership in Alzheimer's Disease (AMP-AD) is a public-private partnership linking NIH, the FDA, pharmaceutical companies, and nonprofit organizations in an interactive, collaborative program utilizing transcriptomics, genomics, metagenomics, proteomics, and metabolomics to provide data for computational analysis, that, in turn, enables promising targets to be ranked by a combination of omic scores and druggability. This ranking informs the selection of targets for validation.
Method: Human postmortem samples were obtained from Mount Sinai, ROSMAP (Religious Orders Study and Rush Memory and Aging Project), Mayo Clinic (Florida), and Columbia University.

Background: It has been suggested that smokers have higher recanalization rate, lower risk of cerebral hemorrhage and better prognosis than non-smokers (smoking paradox) after reperfusion therapy in patients with acute ischemic stroke (IS). This study aimed to assess the effects of smoking on recanalization, intracranial hemorrhage, and clinical outcomes in patients with acute IS following reperfusion therapy.
Methods: Patients were categorized into smokers and non-smokers, with data collected on types of reperfusion therapy, demographics, medication use, comorbidities, stroke etiology, mRS and NIHSS scores, TICI and ECASS classifications.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.

Advanced ovarian cancer often presents with multiple lesions exhibiting varying responses to chemotherapy, highlighting the critical influence of the tumor microenvironment (TME). This study investigates the phenomenon of chemotherapeutic hormesis, wherein low doses of chemotherapeutic agents, such as cisplatin (CDDP) and paclitaxel (PTX), paradoxically stimulate rather than inhibit cancer cell proliferation. Our findings indicate that NOS3 ovarian cancer cells, particularly drug-resistant variants, exhibit enhanced proliferation when exposed to low concentrations of these drugs.
