The study covers treatment results of 220 patients operated on ventral hernia and in vivo experimental treatment of 36 rats proved the nitrogen monoxide (NO) to be the effective means of wound infection prophylaxis. NO potentiates antiseptic effects, minimizing intraoperative wound contamination. It, besides, stimulates endothelial and basal cells of epidermis proliferation. Wound infection was observed only in 9,8% of patients, treated with NO intraoperatively. All cases of infective complications were serous and infiltrative, but not purulent.

Intestinal ischemia-reperfusion injury (IIR/I) significantly increases morbidity and mortality. This study examines the therapeutic effects of geraniol (GNL), which is noted for its anti-inflammatory and antioxidant properties, on intestinal I/R injury in rats. Forty-nine male Wistar-Albino rats were divided into seven groups.

Alternative oxidase (AOX) regulates the level of reactive oxygen species and nitric oxide (NO) in plants. While under normoxic conditions it alleviates NO formation, there are several indications that in the conditions of low oxygen such as during seed germination before radicle protrusion, in meristematic stem cells, and in flooded roots AOX can be involved in the production of NO from nitrite. Whereas the first reports considered this role as indirect, more evidence is accumulated that AOX can act as a nitrite: NO reductase.

Background: The risk of cardiovascular disease (CVD) in patients with chronic kidney disease (CKD) is estimated to be far greater than that in the general population. Adropin regulates endothelial function and may play a role in the pathogenesis of CVD. Angiotensin-converting enzyme inhibitor (ACEI) treatment was reported to have a protective effect on both renal and cardiovascular function.

Mycobacterial hemerythrin-like proteins (HLPs) are important for the survival of pathogens in macrophages. Their molecular mechanisms of function remain poorly defined but recent studies point to their possible role in nitric oxide (NO) scavenging. Unlike any nonheme diiron protein studied so far, the diferric HLP from (-HLP) reacts with NO in a multistep fashion to consume four NO molecules per diiron center.

Background: Parkinson's disease (PD) is characterized by dopaminergic (DA) neuron loss, Lewy body build-up, and motor dysfunction. One of the primary pathogenic mechanisms of PD development is autophagy dysfunction and nitric oxide-mediated neurotoxicity.
Purpose: The current study focuses on autophagy and nitric oxide (NO) signaling roles in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-intoxicated PD mice and their protection by their modulators.
