Prothrombotic Antibodies Targeting the Spike Protein's Receptor-Binding Domain in Severe COVID-19.

Thromboembolic complication is common in severe coronavirus disease (COVID-19), leading to an investigation into the presence of prothrombotic antibodies akin to those found in heparin-induced thrombocytopenia (HIT). In a study of samples from 130 hospitalized patients collected 3.6 days after COVID-19 diagnosis, 80% had IgG antibodies recognizing complexes of heparin and platelet factor 4 (PF4/H), and 41% had antibodies inducing PF4-dependent P-selectin expression in CpG-treated normal platelets.

Assessment of genomic diversity within and between two cryptic shiners, the West Texas shiner (Notropis megalops) and the Texas shiner (Notropis amabilis).

The presence of cryptic species can hinder effective conservation planning and implementation, as has been the case for speciose groups of freshwater fishes that are difficult to differentiate due to conserved morphologies. The West Texas shiner Notropis megalops and the Texas shiner Notropis amabilis are a cryptic pair of leuciscids (minnows) that co-occur in spring-fed tributaries of the Rio Grande in Texas and Mexico. Both N.

Complete mitochondrial genomes of and (Cypriniformes: Leuciscidae).

The Leuciscidae (minnows, shiners and relatives) is a diverse family of freshwater fishes with many species endangered due to anthropogenic stressors. and are two shiners found only in the upper Brazos River basin in Texas, USA and listed as endangered due to contracted habitat. The complete mitochondrial genome was sequenced for two vouchered specimens for each species; having a total mitogenome length of 16,711 bp and having a total mitogenome length 16685-16686 bp, with both including 13 protein-coding genes, 22 transfer RNAs genes, and 2 ribosomal RNA genes.

How Racism and Discrimination Impacts Black Young Women's Sexual Health: The Influence of Racial and Sexual Stereotypes on Educational Access.

Purpose: Structural racism and racial discrimination may increase adverse sexual health outcomes in Black adolescent girls. However, the influence of racism on sexual health has not been well-described in qualitative studies. The purpose of this study was to explore definitions of structural racism and determine how experiences of racial discrimination impact sexual health and decision-making in a sample of adolescent Black girls.

Academy of Breastfeeding Medicine Clinical Protocol #19: Breastfeeding Promotion in the Prenatal Period (Revised 2024).

The Academy of Breastfeeding Medicine revised the 2015 version of this clinical protocol to review the evidence and provide recommendations related to breastfeeding promotion in the prenatal period. Promoting and normalizing breastfeeding in the prenatal period can improve breastfeeding outcomes including initiation and duration of breastfeeding. Ideally, prenatal interventions should be a part of a comprehensive longitudinal breastfeeding support program.
