Proteomics Reveals Divergent Cardiac Inflammatory and Metabolic Responses After Inhalation of Ambient Particulate Matter With or Without Ozone.

Inhalation of ambient particulate matter (PM) and ozone (O) has been associated with increased cardiovascular morbidity and mortality. However, the interactive effects of PM and O on cardiac dysfunction and disease have not been thoroughly examined, especially at a proteomic level. The purpose of this study was to identify and compare proteome changes in spontaneously hypertensive (SH) rats co-exposed to concentrated ambient particulates (CAPs) and O, with a focus on investigating inflammatory and metabolic pathways, which are the two major ones implicated in the pathophysiology of cardiac dysfunction.

Bilateral Tubal Ectopic Pregnancy: A Case Report and Review.

A bilateral ectopic pregnancy is a rare condition, and even more so with spontaneous conception. The known risk factors and clinical presentation are shared by both unilateral and bilateral ectopic pregnancy. This poses a risk for misdiagnosis, treatment failure, and, ultimately, maternal mortality.

Episodic ozone exposure in Long-Evans rats has limited effects on cauda sperm motility and non-coding RNA populations.

Epidemiological evidence suggests the potential for air pollutants to induce male reproductive toxicity. In experimental studies, exposure to ozone during sensitive windows in the sperm lifecycle has been associated with impaired sperm motility. Subsequently, we sought to investigate the effects of episodic exposure to ozone during sperm maturation in the rat.

Proteome Profiling of Rat Brain Cortical Changes during Early Postnatal Brain Development.

Label-free quantitation (LFQ) was applied to proteome profiling of rat brain cortical development during the early postnatal period. Male and female rat brain extracts were prepared using a convenient, detergent-free sample preparation technique at postnatal days (PND) 2, 8, 15, and 22. The PND protein ratios were calculated using Proteome Discoverer, and the PND protein change profiles were constructed separately for male and female animals for key presynaptic, postsynaptic, and adhesion brain proteins.

Association between RCT methodology and disease indication with mineralocorticoid-related toxicity for patients receiving abiraterone acetate for advanced prostate cancer: A meta-analysis of RCTs.

Introduction: While abiraterone acetate (AA) has demonstrated survival benefit in advanced prostate cancer (APC), meaningful cardiotoxicity is observed. It is unclear whether the magnitude differs based on disease indication and concurrent steroid administration.

Methods: We performed a systematic review and meta-analysis of phase II/III RCTs of AA in APC published as of August 11, 2020.
