Dilated cardiomyopathy (DCM) is a serious condition often leading to acute heart failure (HF), with diverse etiologies including viral myocarditis. This report details a case of reversible DCM in a 34-year-old male who presented with symptoms of acute HF. Diagnostic workup revealed biventricular dilation with severe systolic dysfunction and serology confirming herpes simplex virus infection.

The study of brain connectivity has been a cornerstone in understanding the complexities of neurological and psychiatric disorders. It has provided invaluable insights into the functional architecture of the brain and how it is perturbed in disorders. However, a persistent challenge has been achieving the proper spatial resolution, and developing computational algorithms to address biological questions at the multi-cellular level, a scale often referred to as the mesoscale.

Background: Transcriptomics has been used to evaluate immune responses during malaria in diverse cohorts worldwide. However, the high heterogeneity of cohorts and poor generalization of transcriptional signatures reported in each study limit their potential clinical applications.

Methods: We compiled 28 public data sets containing 1556 whole-blood or peripheral blood mononuclear cell transcriptome samples.

The study of male infertility after spinal cord injury (SCI) has enhanced the understanding of seminal plasma (SP) as an important regulator of spermatozoa function. However, the most important factors leading to the diminished sperm motility and viability observed in semen of men with SCI remained unknown. Thus, to explore SP related molecular mechanisms underlying infertility after SCI, we used mass spectrometry-based quantitative proteomics to compare SP retrieved from SCI patients to normal controls.

Endometriosis is a gynecological disease that affects women of reproductive age. The protein profiles of women with endometriosis who were able or unable to achieve pregnancy and women without endometriosis who did achieve pregnancy were compared in this study. The follicular fluid was collected from 21 patients undergoing in vitro-fertilization treatment, according to the following groups: nine women in the control group (Group C), four women with endometriosis who achieved pregnancy (Group E.
