AI Article Synopsis

  • Many drugs can change the heart's ventricular repolarization, visible through T-wave and U-wave alterations on an ECG.
  • These changes are often linked to serious heart rhythm issues known as malignant ventricular arrhythmias.
  • The author discusses various clinical and preclinical screening methods used to predict these arrhythmias, highlighting their effectiveness and related regulatory considerations.

Article Abstract

Many drugs are found to alter ventricular repolarization, as manifest by T-wave and U-wave changes on the surface electrocardiogram. These changes have frequently been associated with malignant ventricular arrhythmias. There is no perfectly sensitive and specific way of anticipating such arrhythmias, but some clinical and preclinical screening methods are better than others. The author reviews some of these methods, commenting on some of the regulatory implications.

Pharmaceuticals, including non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (IBU) and naproxen (NPX), are widely used for medical purposes but have also become prevalent environmental contaminants. However, there is limited understanding of their effects on aquatic organisms, especially regarding multigenerational and mixture exposures. This study aimed to evaluate the toxicological impacts of ibuprofen and naproxen, individually and in combination, on three generations of Daphnia carinata, a freshwater organism.

Objectives: This paper aims to review the immunopathogenesis of Diabetes-associated periodontitis (DPD) and to propose a description of the research progress of drugs with potential clinical value from an immunotherapeutic perspective.

Materials And Methods: A comprehensive literature search was conducted in PubMed, MEDLINE, Embase, Web of Science, Scopus and the Cochrane Library. Inclusion criteria were studies on the association between diabetes and periodontitis using the Boolean operator "AND" for association between diabetes and periodontitis, with no time or language restrictions.

Dysregulated lipid metabolism within the tumor microenvironment (TME) is a critical hallmark of cancer progression, with lipids serving as a major energy source for tumor cells. Beyond their role in cell membrane synthesis, lipids also provide essential substrates for biomolecule production and activate signaling pathways that regulate various cellular processes. Aberrant lipid metabolism impacts not only function but also alters the behavior of immune and stromal cells within the TME.

Department of Urology, Faculty of Health Sciences, Steve Biko Academic Hospital, University of Pretoria, Pretoria, South Africa.

Purpose: Contemporary antiretroviral (ARV) medications are used by millions of men for HIV treatment worldwide. Limited data exist on their direct effect on sperm motility. This pilot study hypothesizes that in vitro exposure to ARVs will reduce sperm kinematic and motility parameter values.

The cerebellum, identified to be active during cognitive and social behavior, has multisynaptic connections through the cerebellar nuclei (CN) and thalamus to cortical regions, yet formation and modulation of these pathways are not fully understood. Perineuronal nets (PNNs) respond to changes in local cellular activity and emerge during development. PNNs are implicated in learning and neurodevelopmental disorders, but their role in the CN during development is unknown.
