Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Defect‐Healed Perovskite Quantum Dots for Optoelectronic Applications in Indoor Photovoltaics and Photoplethysmography

Small, EarlyView.
A novel dispersion‐phase defect‐healing strategy using Br‐doped PbS quantum dots (QDs) significantly stabilizes CsPbI3 perovskite (Pe) QDs by passivating internal vacancies. This approach reduces trap‐assisted nonradiative recombination, enabling high‐performance indoor photovoltaics with exceptional stability.

Measuring stabilized heart rates in the prairie lizard, a small vertebrate ectotherm

Methods in Ecology and Evolution, EarlyView.
Abstract The ability to accurately measure heart rates is vital for studying the ecological and evolutionary pressures on animals because cardiovascular regulation is associated with key physiological responses to environmental change. Heart rates, especially in ectotherms, are influenced by multiple factors over both the short and long term, including

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

Arrhythmias associated with immune checkpoint inhibitor therapy—A clinical perspective

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitors (ICIs) have transformed cancer therapy but are associated with a growing spectrum of cardiovascular immune‐related adverse events. Among these, arrhythmias represent a rare yet potentially life‐threatening complication. ICI‐induced arrhythmias encompass a wide clinical spectrum, including atrial arrhythmias, conduction ...
