Can pumpkin save us of doxorubicin induced cardiotoxicity?

Int. j. morphol; 41 (1), 2023
SUMMARY: Doxorubicin (DOX) is one of the drugs necessary for the treatment of the 10 most common types of cancer. The leading adverse effect limiting clinical use of DOX is cardiotoxicity. Given that literature data indicate a protective role of carotenoids in doxorubicin-induced toxicity, in our study w...

Polymorphisms of the GSTT1 and GSTM1 genes in polycystic ovary syndrome

SUMMARY BACKGROUND: This study aimed to investigate the deletion polymorphisms of the genes of the glutathione S-transferase family GSTT1 and GSTM1 in patients with Polycystic Ovarian Syndrome (PCOS), comparing them with a control population. METHODS: Blood was collected from 219 women (110 with PCOS a...

Determination of insecticides' lethal concentrations and metabolic enzyme levels in Triatoma dimidiata

Salud pública Méx; 62 (4), 2020
Abstract: Objective: The feasibility of the use of WHO impregnated paper and biochemical assays to determine lethal concentrations (LC50 and LC99) and insecticide metabolic enzyme levels of Triatoma dimidiata. Materials and methods: LC50 and LC99 were calculated with WHO papers impregnated at different...

Possible Metsulfuron Herbicide Detoxification by a Oryza sativa L. Glutathione S-transferase Enzyme

Abstract Rice (Oryza sativa L.) is one of the most important crops in the world, and it is considered the primary source of nutritional layout in developing countries in Asia. The glutathione S-transferases (GSTs) superfamily confers to rice protection against biotic and abiotic stress, and herbicide res...

Cáncer de próstata y polimorfismos de la glutation s-transferasa en una población venezolana
Prostate cancer and polymorphisms of the glutathione s-transferase in a population Venezuelan

En vista de la alta prevalencia del cáncer de próstata en la población venezolana y la ausencia de un patrón genético conocido en relación a la expresión de las enzimas Glutatión S-transferasas, se estudió la relación entre la expresión de un polimorfismo nulo de estas enzim...

A study of the association of glutathione S-transferase M1/T1 polymorphisms with susceptibility to vitiligo in Egyptian patients

An. bras. dermatol; 93 (1), 2018
Abstract: Background: The association of glutathione S-transferases M1/T1 (GSTM1/T1) null polymorphisms with vitiligo was proposed in several studies including two Egyptian studies with contradictory results. Objective: The aim here was to assess the association between GSTM1/T1 null polymorphisms and ...
