Glaucoma is an optic nerve head neuropathy in which retinal ganglion cells are lost. A clear association exists between glaucoma and different risk factors, such as high intraocular pressure (IOP) or blood-flow dysregulation. Nitric oxide (NO) and endothelin, two recently identified cellular mediators, appear to be involved in the regulation of IOP as well as in the modulation of ocular blood flow. To some extent, NO is also involved in apoptosis, a mechanism of cell death that can lead to retinal ganglion cell loss in glaucoma. This article provides a short and simplified overview of the biochemistry of NO and endothelin and highlights the potential role of these two mediators in certain important aspects related to the pathogenesis of glaucoma.

Technetium-99m plays a pivotal role in nuclear medicine, offering unique IMAGING capabilities due to its favorable physical and chemical properties. This study investigates the redox behavior and electronic structures of three representative Tc(V) oxo complexes, [TcO(HMPAO)], [TcO(Bicisate)], and [TcO(DMSA)], using computational techniques. Employing relativistic density functional theory with the Zero-Order Regular Approximation (ZORA), we analyze singlet-triplet energy gaps, Gibbs free energy changes, and redox potentials in neutral and acidic environments.

Objectives: Acute T-cell lymphoblastic leukemia (T-ALL) is a severe hematologic malignancy with limited treatment options and poor long-term survival. This study explores the role of IKZF1 in regulating BCL-2 expression in T-ALL.
Methods: CUT&Tag and CUT&Run assays were employed to assess IKZF1 binding to the BCL-2 promoter.
Background: The burden of hospital-acquired infections (HAIs) equates to 3.5 million cases, resulting in more than 90 000 deaths and 2.5 million disability-adjusted life years (DALYs) across Europe.

2-Amino-3-methylimidazole [4,5-] quinoline (IQ) is a kind of heterocyclic amine (HCAs) with high carcinogenicity in hot processed meat. Rutin (Ru) is a flavonoid compound with anti-inflammatory and antioxidant properties. However, whether Ru is scatheless under IQ-stimulated potential unhealthy conditions, especially liver function, in vivo, is unknown.
