background: microglial cells act as the sentinel of the central nervous system .they are involved in neuroprotection but are highly implicated in neurodegeneration of the aging brain. when over-activated, microglia release pro-inflammatory factors, such as nitric oxide (no) and cytokines, which are critical in eliciting neuroinflammatory responses associated with neurodegenerative diseases. thi...

introduction: according to previous studies, colchicine causes neuronal destruction and learning depression. in this project, effects of colchicine injection into the ca1 and interaction between colchicine and nitric oxide (no) in this area on the expression of drug-seeking behavior were investigated. methods: wistar rats (250-300 g) were bilaterally cannulated at the ca1 area. colchicine (2-8 ...

objective: nitric oxide (no) plays an important role both as a consequence and as a cause of epileptic seizures.regarding the central nervous system depressant effects of achillea wilhelmsii (a. wilhelmsii), as well the effects of the plant on no, this study was aimed to elucidatethe possible role for nitric oxide on the effects of hydroalcoholic extract of a. wilhelmsii on pentylenetetrazole (...

a b s t r a c t introduction: mercury is the second most metal pollutant in the world and has the potential to induce many pathologic conditions, especially in nervous system, such as depression. here we tried to find out if nitric oxide has any possible role in the pathophysiology of depression induced by this metal. although the role of nitric oxide has been shown in mood control, here we use...

BACKGROUND Approximately 27% of Americans today are obese, and this condition increases the prevalence of metabolic syndrome and diabetes. The UK Prospective Diabetes Study suggests that loss of beta cell function can begin at least 10 years before diagnosis, and mean beta cell function is already less than 50% at diagnosis. The aim of this research was to assess the possibility of detecting lo...

Gut microbiota has been linked to a number of human diseases including colon cancer. However, the mechanism through which gut bacteria influence colon cancer development and progression remains unclear. Perturbation of the homeostasis between the host immune system and microbiota leads to inflammation and activation of macrophages which produce large amounts of nitric oxide that acts as a genot...

BACKGROUND Reduced bioavailability of endothelium-derived nitric oxide associated with reperfusion could potentially exacerbate the inflammatory response during reperfusion. Evidence suggests the pharmacologic effects of inhaled nitric oxide may extend beyond the pulmonary vasculature, and this is attributed to nitric oxide-derived complexes in blood that ultimately orchestrate antiinflammatory...

This work presents a new optical dual sensor based on PtTFPP-containing electrospun fibers and CsPbBr3 perovskite quantum dots (PQDs) for simultaneous detection of oxygen (O2) nitric oxide (NO) gases, wherein O2 sensing was electrospinning process fabricated by platinum(II) meso-tetrakis (pentafluorophenyl) porphyrin (PtTFPP) complex immobilized in cellulose acetate (CA) matrix. PQDs were used ...
