The role of nitric oxide as a neurotransmitter in the olfactory and chemoreception systems of invertebrates has been well documented. This suggests an early and efficient sensory detection system that is evolutionarily preserved in various species, including vertebrates and invertebrates. Additionally, the presence of a nitric oxide neurotransmitter system has been reported in molluscs, particularly in octopus species. In this work, we present evidence for the existence of nitric oxide synthase in neurons and fibers, as well as its anatomical localization in various nuclei involved in chemosensory integration and the motor responses associated with these processes in Octopus maya.

There is limited knowledge on diffusing capacity in scoliosis patients. It remains to be determined if impaired pulmonary diffusing capacity is mostly influenced by reduced alveolar-capillary membrane diffusing capacity (D), reduced pulmonary capillary blood volume (V) or both. This study aims to report findings from dual test gas pulmonary diffusing capacity for carbon monoxide and nitric oxide (D) with quantification of pulmonary diffusing capacity for carbon monoxide corrected for haemoglobin with a five s breath-hold (D) and nitric oxide with a five s breath-hold (D), D and V.

Contrast-induced acute kidney injury is a common complication marked by reduced kidney function within 48 hours of contrast administration. The aim of this study was to evaluate renal function, anatomy, and molecular changes at 24 hours, 48 hours, and 72 hours post-iodinated contrast media (ICM) administration. This true-experimental study used a post-test-only control group design.

Infections of the nervous system, such as acute bacterial meningitis, pose serious health problems that require immediate intervention. In experimental animals, exposure to lipopolysaccharide (LPS) is used to induce meningitis. Aside from drug intervention to reduce inflammation in meningitis, aerobic exercise helps to maintain the regulatory mechanisms of brain homeostasis through anti-inflammatory mechanisms.

Hydrogen sulfide (H2S) is recognized as an important gaseous signaling molecule, similar to nitric oxide and carbon monoxide. However, the synthesis mechanism of H2S and its role in enhancing rice resistance to Xanthomonas oryzae pv. oryzicola (Xoc) and Xanthomonas oryzae pv.

Oxidative stress and neuronal apoptosis could be an important factor leading to post-hemorrhagic consequences after germinal matrix hemorrhage (GMH). Previously study have indicated that relaxin 2 receptor activation initiates anti-oxidative stress and anti-apoptosis in ischemia-reperfusion injury. However, whether relaxin 2 activation can attenuate oxidative stress and neuronal apoptosis after GMH remains unknown.
