A preterm infant developed recurrent, hypertrophic obstructive cardiomyopathy (HOCM) on administration of steroids which resolved after discontinuation of the drug. Following a course of hydrocortisone for treatment of broncho-pulmonary dysplasia, echocardiography showed left ventricular hypertrophy with outflow tract obstruction, resolving on stopping the drug, only to recur after a second course.

-Methyl-d-aspartate (NMDA) receptors, a subtype of ionotropic glutamate receptors in the central nervous system (CNS), have garnered attention for their role in brain disorders. Specifically, GluN2A-containing NMDA receptors have emerged as a potential therapeutic target for the treatment of depressive disorders and epilepsy. However, the development of GluN2A-containing NMDA receptor-selective antagonists, represented by -(4-(2-benzoylhydrazine-1-carbonyl)benzyl)-3-chloro-4-fluorobenzenesulfonamide (TCN-201) and its derivatives, faces a significant challenge due to their limited ability to penetrate the blood-brain barrier (BBB), hampering their characterization and further advancement.

Cortisol is released upon activation of the hypothalamic-pituitary-adrenal axis, varies across the day, possesses an underlying diurnal rhythm and is responsive to stressors. The endogenous circadian peak of cortisol occurs in the morning, and increases in cortisol observed post-awakening have been named the cortisol awakening response (CAR) based on the belief that the act of waking up stimulates cortisol secretion. However, objective evidence that awakening induces cortisol secretion is limited.

Application of algicides produced by naturally occurring bacteria is considered an environmentally friendly approach to control harmful algal blooms. However, few studies assess the effects of bacterial algicides on non-target species, either independently or with other stressors. Here, we measured sub-lethal effects of dinoflagellate-specific algicide IRI-160AA on the estuarine fish Fundulus heteroclitus and Menidia menidia in laboratory experiments.

The purpose of the current study was to investigate the potential ameliorating murine reproductive effects of herbal tea extracts against bisphenol A-induced (BPA) cytotoxicity. A comparative study was applied among red, green and blue teas in mice groups. Samples were coded as RTE, GTE and BTE groups, respectively.
