Methamphetamine Neurotoxicity: Neurotoxic Effects, Mechanism of Toxicity, Molecular Mechanisms and Treatment Strategies.

Methamphetamine (METH) is a highly addictive and dangerous drug that mainly affects neurotransmitters in the brain and leads to feelings of alertness and euphoria. The METH use can lead to addiction, which has become a worldwide problem, resulting in a slew of public health and safety issues. Recent studies showed that chronic METH use can lead to neurotoxicity, neuro-inflammation and oxidative stress which can lead to neuronal injury.

Xanthones: A Class of Heterocyclic Compounds with Anticancer Potential.

Xanthones (9H xanthen-9-one) are an important class of heterocyclic compounds containing oxygen and a moiety of gamma-pirone, dense with a two-benzene ring structure, distributed widely in nature. Naturally occurring xanthones are found in micro-organisms and higher plants as secondary metabolites in fungi and lichens. Compounds of the family Caryophyllaceae, Guttiferae and Gentianaceae, are the most common natural source of xanthones.

Nanoparticles in clinical trials of COVID-19: An update.

Once the World Health Organization (WHO) declared the COVID-19 (Coronavirus Infectious Disease-19) outbreak to be pandemic, massive efforts have been launched by researchers around the globe to combat this emerging infectious disease. Strategies that must be investigated such as expanding testing capabilities, developing effective medicines, as well as developing safe and effective vaccines for COVID-19 disease that produce long-lasting immunity to human system. Now-a-days, bio-sensing, medication delivery, imaging, and antimicrobial treatment are just a few of the medical applications for nanoparticles (NPs).

Protective Role of Ethanolic Extract Against Dimethoate-induced Hepatotoxicity in Guinea Pigs.

Background And Objective: Carissa edulis (CE) (Apocynaceae) is distributed in tropical Africa and Asia and commonly used in folk medicine to treat many diseases such as headache, cough, rheumatism and fever. The purpose of this study was to evaluate the protective role of ethanolic extract of CE, a medicinal plant locally called "Al-Arm" in Yemen, against liver injury induced by dimethoate (DM) intoxication in male guinea pigs.

Materials And Methods: Animals were divided randomly into 5 groups and kept at 5 animals per group.

Protective Role of Achillea biebersteinii Pretreatment on Dimethoate Induced Oxidative Stress in Guinea Pigs Liver.

Objective: The present study investigated the influence of Achillea biebersteinii (Ab), a medicinal herb used widely in Yemeni's folk medicine as analgesic, antipyretic, against diarrhea and flatulence and for liver diseases, on the liver antioxidant potential of guinea pigs acutely intoxicated with dimethoate pesticide (DM).

Materials And Methods: Animals were administered with Ab aqueous extract (50 and 100 mg kg-1 b.wt.
