The effects of tetramethrin and prallethrin exposure on plasma total proteins, free amino acids, albumins, urea, urea nitrogen, uric acid, creatinine were tested. Serum SGOT, SGPT and lipid profile, antioxidants super oxide dismutase (SOD), catalase, GSH, G-Px, phospholipids, cholesterol, C/P ratio in membranes of erythrocyte and membrane fluidity were analyzed. The reason of the study were analyzed to examine the possessions of mosquito repellent pyrethroid (MRP) based compounds tetramethrin and prallethrin exposure on plasma profile, antioxidant status of erythrocyte membrane, membrane fluidity in male
Wistar
rats. We tested chronically for three months exposure every day (continuously for 8–10 h per day by inhalation) of tetramethrin and prallethrin markedly available (MRP) repellents treated on male
Wistar
rats. Our results confirmed that tetrarmethrin and prallethrin treatment effect of plasma profile alterations, and lipid homeostasis mechanism in Red Blood cells (RBCs). Tetramethrin and prallethrin treatment significantly increased in erythrocyte membrane phospholipids and decreased levels of cholesterol with no change of protein content, increased C/P ration levels. Inhalation of tetramethrin and prallethrin stimulate plasma biophysical and biochemical modify SGOT, SGPT, erythrocyte membrane cholesterol and phospholipid levels, individual phospholipids and membrane fluidity of exposure rats compared to controls.
Iron oxides have become increasingly popular for their use as a diagnostic and therapeutic tool in oncology. This study aimed to improve pharmacological valuable of Fe

magnetic resonance imaging (MRI) experiments in (HCT 116) and human embryonic kidney cells (HEK 293) illustrated that nanohybrid is an effective MRI contrasting agents for the diagnosis of colorectal cancer.
Lung cancer is considered as one of the most serious disease worldwide. The progress of drug carriers based on nonmaterial, which selectively hold chemotherapeutic agents to cancer cells, has become a major focus in biomedical research. This study aimed to evaluate the growth inhibition and apoptosis induction of the human lung cancer cells (A-549) by Q-loaded SBA-15 conjugate system. Mesoporous silica nanoparticles (SBA-15) as host materials for transporting therapeutics medicaments were fabricated for targeted drug delivery toward lung cancer. With the objective of increasing bioavailability and aqueous solubility of flavonoids, SBA-15 was successfully loaded with the quercetin (Q)—a major flavonoid and characterized with the help of Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The biological investigation on A549 cell line confirmed that the efficacy of Q-SBA-15 is much higher than only Q. Moreover, the apoptotic pathway of synthesized Q-SBA-15 NPs examined that the Q-SBA-15–mediated apoptosis via PI3K/AKT/mTOR signaling pathway. Thus, the newly conjugated Q-SBA-15 system improved the apoptotic fate through caspase-mediated apoptosis via PI3K/AKT/mTOR signaling pathway and hence, it can be potentially employed as an anticancer agent for lung cancer.
Islet amyloid polypeptide (amylin), consecrated by the pancreatic β-cells with insulin, has a significant role to play in maintaining homeostasis of islet cell hormones. Alzheimer's disease is the predominant source of dementia. However, its etiology remains uncertain; it appears that type 2 diabetes mellitus and other prediabetic states of insulin resistance contribute to the intermittent Alzheimer's disease presence. Amylin is abnormally elevated in Type II diabetes patients, accumulated into amylin aggregates, and ultimately causes apoptosis of the β-cells, and till date, its mechanism remains unclear. Several flavonoids have inhibitory effects on amylin amyloidosis, but its inhibition mechanisms are unknown. Screening a collection of traditional compounds revealed the flavone Chrysin, a potential lead compound. Chrysin inhibits amyloid aggregate formation according to Thioflavin T binding, turbidimetry assay. We report results of molecular interaction analysis of Chrysin with amylin which shows potent binding affinity against amylin. Pharmacokinetics and Drug likeness studies of Chrysin also suggest that it is a potential lead compound. Therefore, Chrysin prevented amylin aggregation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
