Spherocytosis in Newborn Secondary to Novel Heterozygous Mutation in Gene: Case Report.

This case report describes a novel mutation of the gene as a potential pathogenic cause of spherocytosis. A 3-week-old male presented with clinical and laboratory signs consistent with hemolytic spherocytosis, including jaundice, hyperbilirubinemia, anemia, reticulocytosis, negative Coombs test, no ABO or Rh incompatibility, and a peripheral blood smear notable for numerous spherocytes. His laboratory work demonstrated persistent anemia despite daily folate prompting next-generation sequencing which revealed a novel mutation in the gene resulting in a nonfunctioning protein product.

Adolescent and young adult couples' views of intravaginal practices: a qualitative analysis of a pilot study.

Purpose: In this study, we evaluated the risk behaviors that are drivers of the HIV epidemic among adolescent girls and young women in Zambia using a focus group research technique.

Subjects And Methods: Eighteen adolescent couples (n=18 females and 18 males) aged 16-24 participated in six focus groups discussions (3 per gender) convened at three health facilities in Lusaka, Zambia. Focus group moderators utilized a set of open-ended questions to guide the 60-minute sessions.

Polyclonal IgE induces mast cell survival and cytokine production.

Background: Ag-dependent activation of IgE-bearing mast cells is a critical first step in immediate hypersensitivity and other allergic responses. Recent studies have revealed Ag-independent effects of monoclonal mouse IgE molecules on mast cell survival and activation. However, no studies have been performed on the effects of polyclonal IgE molecules.

IgE influences the number and function of mature mast cells, but not progenitor recruitment in allergic pulmonary inflammation.

Studies performed using cultured cells indicate that IgE functions not only to trigger degranulation of mast cells following allergen exposure, but also to enhance their survival. Such an influence of IgE on mast cell homeostasis during allergic responses in vivo has not been established. In this study, we show that inhalation of Aspergillus fumigatus extract in mice induced a dramatic rise in IgE accompanied by an increase in airway mast cells.

Stromal cell-derived factor-1 (chemokine C-X-C motif ligand 12) and chemokine C-X-C motif receptor 4 are required for migration of gonadotropin-releasing hormone neurons to the forebrain.

Gonadotropin-releasing hormone (GnRH) neurons migrate from the vomeronasal organ (VNO) in the nasal compartment to the basal forebrain in mice, beginning on embryonic day 11 (E11). These neurons use vomeronasal axons as guides to migrate through the nasal mesenchyme. Most GnRH neurons then migrate along the caudal branch of the vomeronasal nerve to reach the hypothalamus.
