Tadalafil pretreatment attenuates doxorubicin-induced hepatorenal toxicity by modulating oxidative stress and inflammation in Wistar rats.

Doxorubicin (DOX) is a widely used anticancer agent, but its clinical application is limited by significant off-target hepatorenal toxicity. Tadalafil (TAD), a selective phosphodiesterase-5 inhibitor used mainly for erectile dysfunction and pulmonary arterial hypertension, has shown potential in reducing oxidative stress. This study investigated TAD's chemoprotective effects and underlying mechanisms in DOX-induced hepatorenal toxicity in rats over 12 days.

Anti-apoptotic and antioxidant mechanisms may underlie the abrogative potential of Linn. Leaf extract and fractions against trastuzumab-induced cardiotoxicity in Wistar rats.

Clinical use of trastuzumab (), has been widely associated with increased incidence of cardiotoxicity. Linn. is a household medicinal plant popularly used for treating inflammatory conditions.

A survey of chloroquine use for prevention and treatment of COVID-19 in Nigeria.

Background: Rampant chloroquine/hydroxychloroquine poisoning in Nigerian hospitals following suggestions of its possible efficacy in the treatment and prevention of the newly emerged COVID-19 disease informed this survey.

Objectives: The aim of this study was to assess the knowledge, attitude and perception of the Nigerian populace on the use of chloroquine in the COVID-19 pandemic.

Methods: This cross-sectional study was done by administering an electronic questionnaire created using Google Docs, through social media cascade methods including the WhatsApp application software to capture data on chloroquine use between April 20 and June 20, 2020.

Oxidized dietary lipids induce vascular inflammation and atherogenesis in post-menopausal rats: estradiol and selected antihyperlipidemic drugs restore vascular health in vivo.

Background: Thermoxidation of edible oil through deep fat frying results in the generation of several oxidized products that promote lipid peroxidation and ROS production when eaten. Consumption of thermoxidized oil in post-menopausal conditions where the estrogen level is low contributes to cardiovascular disease. This study evaluates the role of estradiol and antihyperlipidemic agents (AHD) in restoring the vascular health of ovariectomized (OVX) rats fed with thermoxidized palm oil (TPO) and thermoxidized soya oil (TSO) diets.

Selected Antihypertensive Agents and Their Fixed-Dose Combinations Effectively Ameliorate Trastuzumab-Mediated Cardiac Dysfunction In Rats.

This study evaluates the therapeutic potentials of selected antihypertensive drugs [valsartan, amlodipine, lisinopril and their fixed-dose combinations (amlodipine + lisinopril) and (valsartan + lisinopril)] in ameliorating trastuzumab (TZM)‑induced cardiac dysfunctions in experimental rats. After an ethical clearance for the study was obtained, in-bred young adult female Wistar rats were randomly allotted into 10 groups of 6 rats per group. Group I rats were treated with 10 ml/kg/day sterile water p.
