Stroke Prevention in Hispanic Children with Sickle Cell Anemia: the SACRED trial.

Sickle cell anemia (SCA) is recognized globally, but little is known about affected Hispanic populations. In partnership with Dominican Republic, a Hispanic Caribbean Island with a large SCA population, a TCD screening program provided hydroxyurea to children with conditional velocities. Building local capacity, ten Dominican medical graduates were certified in TCD examinations and trained in hydroxyurea management.

Genetic parameters and genome-wide association studies including the X chromosome for various reproduction and semen quality traits in Nellore cattle.

Background: The profitability of the beef industry is directly influenced by the fertility rate and reproductive performance of both males and females, which can be improved through selective breeding. When performing genomic analyses, genetic markers located on the X chromosome have been commonly ignored despite the X chromosome being one of the largest chromosomes in the cattle genome. Therefore, the primary objectives of this study were to: (1) estimate variance components and genetic parameters for eighteen male and five female fertility and reproductive traits in Nellore cattle including X chromosome markers in the analyses; and (2) perform genome-wide association studies and functional genomic analyses to better understand the genetic background of male and female fertility and reproductive performance traits in Nellore cattle.

n. sp. (Cnidaria: Myxosporea) parasitizing (Bloch 1794) from Tartarugalzinho river, eastern Amazon.

The Amazon basin has the largest number of fish in the world, and among the most common fishes of the Neotropical region, the threespot () is cited, which in relation to its microparasitic fauna, has described only 1 species of the genus , . The Myxozoa class is considered an obligate parasite, being morphologically characterized by spores formed by valves connected by a suture line. This study describes a new species of sp.

Predicting nodal response to neoadjuvant treatment in breast cancer with core biopsy biomarkers of tumor microenvironment using data mining.

Purpose: To generate a model for predicting nodal response to neoadjuvant systemic treatment (NAST) in biopsy-proven node-positive breast cancer patients (cN+) that incorporates tumor microenvironment (TME) characteristics and could be used for planning the axillary surgical staging procedure.

Methods: Clinical and pathologic features were retrospectively collected for 437 patients. Core biopsy (CB) samples were reviewed for stromal content and tumor-infiltrating lymphocytes (TIL).
