Stability-indicating spectrophotometric manipulations for the determination of Letrozole in the presence of its alkali-induced degradation products; towards whiteness and ChlorTox scale perspectives.

Letrozole (LTZ) is an established first hormonal treatment for breast cancer, yet it was found to be highly susceptible for degradation in alkaline medium due to the presence of cyano phenyl group. Consequently, three stability-indicating spectrophotometric manipulations for LTZ quantification in presence of its alkali-induced degradation products were developed for the first time; ensuring methods' simplicity, sensitivity and accuracy. The first method was Second derivative (D) by recording peak amplitude of the drug at 226.

A comparative study on the effect of melatonin and orlistat combination versus orlistat alone on high fat diet-induced hepatic changes in the adult male albino rats (a histological and morphometric study).

Background: Nonalcoholic fatty liver disease (NAFLD) is the extremely usual reason of chronic liver disease, extending from simple hepatic steatosis (HS), nonalcoholic steatohepatitis (NASH) to advanced hepatic fibrosis and cirrhosis. Though orlistat is a Food and Drug Administration (FDA) approved drug for long-duration management of obesity, few cases of severe hepatic insult were declared. Melatonin is an efficient antioxidant; it also regulates metabolic processes that lead to fat accumulation and obesity.

Possible protective effect of natural flavanone naringenin-reduced graphene oxide nanosheets on nonalcoholic fatty liver disease.

Utilizing naringenin as a safe, natural compound for reducing graphene oxide and to determine whether Nar-RGO more effectively mitigates the harmful effects of HFFD-induced NAFLD compared to crude naringenin. Using a straightforward experimental setup, we utilize the bioactive flavonoid naringenin (NAR) as the reducing agent to synthesize naringenin-reduced graphene oxide nanosheets (Nar-RGO). Naringenin loading on graphene oxide was validated using electroscopic methods (SEM and TEM) and zeta potential measurements.

Magnetized cubic zinc MOFs for efficient removal of hazardous cationic and anionic dyes in aqueous solutions.

A significant amount of dye runoff and aqueous waste are released from the manufacturing process of dyes with intense and permanent colors, which are undesirable from a cultural and ecological aspect. In this paper, we present a green, simple, low-effort, and energy-efficient method of creating magnetized cubic Zn-MOFs for the adsorption and elimination of various organic dyes. Magnetic iron oxide materials with a hierarchical structure were loaded and doped into cubic zinc metal-organic frameworks (MDLZ).
