Dyspareunia is rarely assessed in rodent models of endometriosis and interstitial cystitis/bladder pain syndrome: a systematic review.

Dyspareunia, or pain during sex, is a common and often-debilitating symptom in individuals with endometriosis and/or interstitial cystitis/bladder pain syndrome (IC/BPS). Despite its significant impact on quality of life, it is frequently overlooked in research. This review evaluates how dyspareunia has been addressed in preclinical investigations of these conditions.

Mitochondrial metabolism and epigenetic crosstalk drive the SASP.

Senescent cells drive tissue dysfunction through the senescence-associated secretory phenotype (SASP). We uncovered a central role for mitochondria in the epigenetic regulation of the SASP, where mitochondrial-derived metabolites, specifically citrate and acetyl-CoA, fuel histone acetylation at SASP gene loci, promoting their expression. We identified the mitochondrial citrate carrier (SLC25A1) and ATP-citrate lyase (ACLY) as critical for this process.

JUNB O-GlcNAcylation-Mediated Promoter Accessibility of Metabolic Genes Modulates Distinct Epithelial Lineage in Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a lethal disease with substantial unmet medical needs. While aberrant epithelial remodeling is a key factor in IPF progression, the molecular mechanisms behind this process remain elusive. Harnessing a 3D patient-derived organoid model and multi-omics approach, the first inventory of the connection between metabolic alteration, chromatin accessibility, and transcriptional regulation in IPF aberrant epithelial remodeling is provided.

Competitive co-diffusion as a route to enhanced step coverage in chemical vapor deposition.

Semiconductor devices are constructed from stacks of materials with different electrical properties, making deposition of thin layers central in producing semiconductor chips. The shrinking of electronics has resulted in complex device architectures which require deposition into holes and recessed features. A key parameter for such deposition is the step coverage (SC), which is the ratio of the thickness of material at the bottom and at the top.

Tris(4-chloro-phen-yl) phosphate.

The title compound, CHClOP, is the symmetric phosphate derived from -chloro-phenol and phospho-ric acid. Two of the three aromatic moieties adopt -orientation towards the P=O bond while the last chloro-phenol ring is pointing away from this bond. In the extended structure, C-H⋯O bonds connect the individual mol-ecules into sheets lying perpendicular to the crystallographic axis.
