The Impact of Clinical Features on Survival and Relapse of Patients Diagnosed With T-cell Acute Lymphoblastic Leukemia - a Multicenter Cohort Study.

Background: T-cell acute lymphoblastic leukemia (T-ALL) remains understudied compared to B-cell ALL, especially in Latin America. Different biology and response to chemotherapy have been described.

Methods: This retrospective multi-site cohort study analyzed data from 152 newly diagnosed T-ALL patients aged 15 years and above, between January 2010 and June 2022.

The radiographic diversity of dental patterns among 7219 young individuals-a contribution to disaster victim identification.

The diversity of dental patterns is a fundamental topic in disaster victim identification. The current scientific literature, however, is scarce of data regarding young individuals. This study aimed to assess the radiographic diversity of dental patterns, considering missing, unrestored, and filled teeth in young individuals.

Crassicaudiasis in three geographically and chronologically distant Cuvier's beaked whales () stranded off Brazil.

The Cuvier's beaked whale (CBW; ) is a cosmopolitan marine mammal found in deep tropical and temperate waters of all oceans. CBW strandings have been recorded sporadically in Brazil; however, there is lack of information available regarding their causes of stranding and/or death. Herein, we report the epidemiologic, pathologic, morphologic parasitologic features and molecular identification of arterial and renal crassicaudiasis by sp.

Multi-biomarker responses to pesticides in an agricultural population from Central Brazil.

We evaluated farmworkers exposed to pesticides and individuals with no history of occupational exposure to pesticides. It was performed the comet assay to evaluate DNA damage. The immunophenotyping of TCD4 lymphocyte subpopulations in peripheral blood was performed by flow cytometry.

Microscopic analysis of subcutaneous reactions to endodontic sealer implants in rats.

The reaction of subcutaneous tissues to Endofill, Endomethasone, Sealer 26, and AH-Plus was investigated microscopically after implantation of in rats polyethylene cannulae, obturated with gutta-percha cones and sealers, in rats. Empty polyethylene cannulae and cannulae filled with gutta-percha cones alone were used as controls. The inflammatory reactions caused by the sealers were evaluated 7, 14, and 30 days after implantation using a descriptive, histopathological analysis.

Randomly amplified polymorphic DNA as a valuable tool for epidemiological studies of Paracoccidioides brasiliensis.

Randomly amplified polymorphic DNA (RAPD) has been successfully used to detect genetic variations among isolates of Paracoccidioides brasiliensis. However, the usefulness of this technique for assessing important parasitic properties is still unconfirmed. In the present work we further investigated the applicability of RAPD in revealing important intrinsic and extrinsic features of this fungus associated with geographical origin, time of isolation, source of clinical specimen, clinical forms of human disease and also in vitro and in vivo susceptibility to antimicrobial and antifungal drugs.
