Purpose: To compare hydroxyproline and nitric oxide levels, and fluid acidity between sac tissues from inguinal hernia, hydrocele and undescended testis patients.
Material And Method: Thirty patients were in the inguinal hernia group, 11 patients in the hydrocele group and 5 patients in the undescended testis with inguinal hernia group. Intrasaccular fluid acidity, and nitric oxide and hydroxyproline levels in sac tissues were measured and analyzed statistically between groups.
Results: Intrasaccular fluid could be obtained from 24 inguinal hernia and 6 hydrocele patients. Acidity level (pH) was 7.5 ± 0.74 in the hernia group and 7.86 ± 0.63 in the hydrocele group (p < 0.05). All patients in the three groups were evaluated for nitric oxide and hydroxyproline. Results for hydroxyproline (mg/g dry tissue)/nitric oxide (nmol/g wet tissue) were 3.53 ± 0.54/2.02 ± 0.39 for inguinal hernia, 2.89 ± 0.9/1.92 ± 1.05 for hydrocele and 3.02 ± 1.23/2.86 ± 1.09 for undescended testis group (p > 0.05).
Conclusion: Hydroxyproline and nitric oxide pathways do not seem to be responsible for the different characteristics of inguinal diseases. However, differences in the acidity of sac fluid may be evidence of the different mechanisms of hernia and hydrocele formation.

Receptors for the vasoactive adipokine apelin, termed APJ receptors, are G-protein-coupled receptors and are widely expressed throughout the cardiovascular system. APJ receptors can also signal via G-protein-independent pathways, including G-protein-coupled-receptor kinase 2 (GRK2), which inhibits nitric oxide synthase (eNOS) activity and nitric oxide (NO) production in endothelial cells. Apelin causes endothelium-dependent, NO-mediated relaxation of coronary arteries from normotensive animals, but the effects of activating APJ receptor signaling pathways in hypertensive coronary arteries are largely unknown.

Background And Aim: In the context of gastrointestinal diseases, the role of monoacylglycerol lipase (MAGL) is significant. Therefore, the objective of this study was to examine the protective effects of MAGL inhibition using JZL184 in rat models of severe acute pancreatitis (SAP) and to explore its mechanism.
Methods: In this study, a rat model of SAP was established, and the rats were divided into three groups for treatment: the Control group (CON), the SAP group (SAP), and the SAP group treated with JZL184 (JZL184).

In this study, Chinese yam polysaccharides (CYPs) were fermented using M616, and changes in the chemical composition, structure, and anti-inflammatory activity of CYPs before and after fermentation were investigated. The carbohydrate content of M616-fermented CYP (CYP-LP) increased from 71.03% ± 2.

Introduction: Up to 20% of patients with traumatic brain injury (TBI) develop acute respiratory distress syndrome (ARDS), which is associated with increased odds of mortality. Guideline-based treatment for ARDS includes "lung protective" ventilation strategies, some of which are in opposition to "brain protective" strategies used for ventilation with patients with TBI. We conducted a scoping review of ventilation management strategies with clinical outcomes among patients with TBI and ARDS.

Necroptosis is a finely regulated programmed cell death process involving complex molecular mechanisms and signal transduction networks. Among them, receptor-interacting protein kinase 1 (RIPK1), receptor-interacting protein kinase 3 (RIPK3) and mixed lineage kinase domain-like protein are the key molecules regulating this process. In recent years, gasotransmitters such as nitric oxide, carbon monoxide and hydrogen sulfide have been suggested to play a regulatory role in necroptosis.
