The current study provides the first ultrastructural observations on the intraerythrocytic stages of so-called Haemogregarina damiettae and their cytopathological effects on the infected erythrocytes (IEs) in addition to the recording of new morphometric data. The intraerythrocytic stages are attributed to the immature forms or trophozoites (Ts), and mature gamonts (Gs). Ts are typically bowling-bottle shaped with nucleus (TN) occupying its globose part, while Gs are typically banana- shaped.

Cisplatin is an antineoplastic drug that exhibits toxicity dependent on dosage and has adverse reproductive effects. (Bitter melon) is a natural vegetable plant; its active ingredients possess antioxidant, apoptotic, antiproliferative, hypoglycemic, and other therapeutic properties. This study evaluates the effect of the administration of bitter melon extract, cisplatin, and cisplatin/bitter melon cotreatment on liver and kidney functions, serum and testicular oxidative status, testis histology, and sperm parameters.

Chronic migraine (CM) is a disabling neurological disease. Astragaloside IV (AS-IV), a natural product derived from Astragalus membranaceus, shows great potential in treating chronic pain by relieving inflammation and oxidative stress. This study aimed to investigate the effects and mechanisms of action of AS-IV on CM.

Metastasis of alveolar soft part sarcoma (ASPS) to the adrenal gland is infrequent, with only eight patients reported in the literature. Here we present an ASPS in an adolescent girl presented as a hypervascular adrenal incidentaloma along with a review of the available literature. This study aims to serve as a reference to aid in the pre-operative radiological and histopathological diagnosis of this rare entity.

The genus Wittmackia has 44 species distributed in two centers of diversity: the Brazilian clade and the Caribbean clade. The Brazilian clade includes 29 species, with geographic distribution concentrated in the Northeast of Brazil. This study reports the morphology, ultrastructure, pollen viability and stigma receptivity by different microscopy techniques of 23 species of the genus Wittmackia endemic to Brazil and occurring in Atlantic Forest areas.
