Inflammatory mediators - chitotriosidase-1 (CHIT1) and leukocyte elastase (LE) - were analyzed in human seminal plasma in relation to total antioxidative status (TAS) and pro-inflammatory markers IL-1β and IL-6. Samples collected from 34 males who were part of infertile couples were divided into normozoospermic (N; n = 12, without symptoms of inflammation), oligozoospermic (O; n = 11) and teratozoospermic (T; n = 11) groups. significant differences were observed only in CHIT1 concentration between N and O samples. However, a higher mean LE concentration was also observed in O and T patients (3.7-times and 900-times, respectively) compared with the N group. in IL-1β and IL-6 concentrations, an upward trend was observed from N, through O, up to the T group. The positive correlation between the concentration of IL-1β and the activity and specific activity of CHIT11 as well as the moderate negative correlation between concentrations of IL-1β and CHIT1 may suggest that elevated CHIT11 levels appeared in early stages of inflammation before the increase in IL-1β concentrations, or remained stable even after the levels of cytokine decreased. The above seem to confirm the role of CHIT1 in the manifestation of 'silent' inflammation at a very early stage. To conclude, CHIT1 concentration appears to be an interesting biomarker that signals the presence of possible 'silent' inflammation accompanying oligozoospermia. We cannot draw such conclusions regarding LE concentration, because, although we observed differences in the mean values and medians between analyzed groups, they were not significant. The utility of CHIT1 in the follow-up of oligozoospermia-associated 'silent' subclinical inflammation is promising, but further studies on a larger patient test set are required.

Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

While it has a significant impact on their social life, it is also supposedly linked with various comorbidities, of which, cardiovascular disease (CVD) is the most frequently reported. Various biological, behavioral, and genetic mechanisms are thought to play a role: hypothalamic-pituitary-adrenal axis, autonomic nervous system dysregulation, inflammation, and psychotropic medications.

Chronic liver disease is characterised by persistent inflammation, tissue damage, and regeneration, which leads to steatosis, fibrosis, and, lastly, cirrhosis and hepatocellular carcinoma (HCC). HCC, the most prevalent form of primary liver cancer, is one of the leading causes of cancer-related mortality worldwide. The gut microbiota plays a fundamental role in human physiology, and disturbances in its critical balance are widely recognised as contributors to various pathological conditions, including chronic liver diseases, both infectious and non-infectious in nature.

Early detection of hepatitis C virus (HCV) infection is crucial for eliminating this silent killer, especially in resource-limited settings. HCV core antigen (HCVcAg) represents a promising alternative to the current "gold standard" HCV RNA assays as an active viremia biomarker. Herein, a highly sensitive electrochemical magneto-immunosensor for the HCVcAg was developed.

Previous studies have demonstrated the dynamic changes in chromatin structure during retinal development correlate with changes in gene expression. However, those studies lack cellular resolution. Here, we integrate single-cell RNA sequencing (scRNA-seq) and single-cell assay for transposase-accessible chromatin sequencing (scATAC-seq) with bulk data to identify cell-type-specific changes in chromatin structure during human and murine development.
