Unlabelled: The aim of the study was to assess the efficacy and safety of taking tadalafil at a dose of 5 mg per day or 20 mg "on demand" for the state of endothelial function, the severity of erectile dysfunction (ERD) and urodynamics in men with mild to moderate ERD.
Materials And Methods: The study included 60 male patients with benign prostatic hyperplasia aged 44 to 60 years with erectile dysfunction and cardiovascular pathology (arterial hypertension, ischemic heart disease). All patients were divided into 3 groups of 20 people. Patients of the 1st group for the treatment of ERD were prescribed tadalafil (Tadalafil SZ, NAO Severnaya Zvezda) in a daily dose of 5 mg / day. Men of the 2nd group took tadalafil 20 mg "on demand", but at least 1 time per week. The third group, in which tadalafil was not prescribed, served as a control. The duration of the study was 4 weeks.
Results: A significant effect of tadalafil on indicators of endothelial dysfunction (endothelin-1, nitric oxide, stiffness and reflection index, endothelial function indicator) was demonstrated. The use of tadalafil at a dose of 5 mg daily for four weeks has been shown to be advantageous compared to the use of 20 mg "on demand". Daily intake of tadalafil at a dose of 5 mg and 20 mg "on demand" was safe for patients with cardiovascular disease.
Conclusion: The data obtained make it possible to recommend this drug for the correction of endothelial dysfunction in patients with benign prostatic hyperplasia, including patients with concomitant cardiovascular diseases.

Atherosclerosis is the leading cause of cardiovascular disease and myocardial infarction. Precise and effective plaque targeting is a major objective for therapeutic outcomes throughout various stages of atherosclerosis. Inspired by the natural recruitment of neutrophils in atherosclerotic plaques, we fabricated a simvastatin (ST)-loaded and neutrophil membrane-cloaked nanoplatform (NNP) for enhancing localized payload delivery and atherosclerosis management.

Artificial intelligence (AI) and machine learning (ML) are driving innovation in biosciences and are already affecting key elements of medical scholarship and clinical care. Many schools of medicine are capitalizing on the promise of these new technologies by establishing academic units to catalyze and grow research and innovation in AI/ML. At Stanford University, we have developed a successful model for an AI/ML research center with support from academic leaders, clinical departments, extramural grants, and industry partners.

Background: In 2020, loosened federal regulations allowed for buprenorphine for opioid use disorder to be initiated via telemedicine. In response to these regulatory changes and growing racial inequities in overdose in St. Louis, MO, a local, peer-led outreach program incorporated a new rapid access (RA) to buprenorphine program.

Objectives: Whether intermediate-dose tertiary prophylaxis can improve quality of life and psychological health in adults with severe/moderate hemophilia A has not been determined. This research aims to explore the impact of intermediate-dose tertiary prophylaxis with recombinant human FVIII (rhFVIII) on quality of life, anxiety and depression in such individuals transitioned from on-demand treatment.
Methods: This retrospective analysis collected data from July 2019 to July 2022.

The design of biomaterials that can reconfigure on-demand in response to external stimuli is an emerging area in materials research. However, achieving reversible assembly of protein-based biomaterials by light input remains a major challenge. Here, we present the engineering of a new protein material that is capable of switching between liquid and solid state reversibly, controlled by lights of different wavelengths.
