Marburg and Ebola Virus Infections Elicit a Complex, Muted Inflammatory State in Bats.

The Marburg and Ebola filoviruses cause a severe, often fatal, disease in humans and nonhuman primates but have only subclinical effects in bats, including Egyptian rousettes, which are a natural reservoir of Marburg virus. A fundamental question is why these viruses are highly pathogenic in humans but fail to cause disease in bats. To address this question, we infected one cohort of Egyptian rousette bats with Marburg virus and another cohort with Ebola virus and harvested multiple tissues for mRNA expression analysis.

Acute and chronic maternal exposure to fine particulate matter and prelabor rupture of the fetal membranes: A nation-wide survey in China.

Background: Prelabor rupture of the fetal membranes (PROM) is a major contributor to adverse perinatal outcomes. Some epidemiologic studies explored the association between maternal PM exposure and PROM but failed to treat the labor induction and prelabor cesarean section as censored observations.

Objective: We aimed to evaluated whether acute and chronic maternal ambient PM exposure may increase the risk of PROM in China.

Insulin prevents liver damage and preserves liver function in lipopolysaccharide-induced endotoxemic rats.

Background/aims: Liver integrity and function are crucial for survival of patients suffering from trauma, operations or infections. Insulin decreased mortality and prevented the incidence of multi organ failure and infection in critically ill patients. The aim of the present study was to determine whether insulin exerts positive effects on hepatic homeostasis and function during endotoxemia.

Modulation of types I and II acute phase reactants with insulin-like growth factor-1/binding protein-3 complex in severely burned children.

Objective: To determine whether 0.5 mg/kg insulin-like growth factor (IGF)-1/binding protein (IGFBP)-3, given intravenously, effectively alters the acute phase response in severely burned children.

Design: Longitudinal trial with each patient serving as their own control.

Langerhans cell histiocytosis in a child while in remission for acute lymphocytic leukemia.

The occurrence of Langerhans cell histiocytosis (LCH) and malignancy in the same patient is rare. When LCH occurs concomitantly with acute leukemia, distinct temporal patterns often exist; acute myelogenous leukemia (AML) typically succeeds LCH, whereas acute lymphocytic leukemia (ALL) usually precedes it. We report a case of LCH developing in a child while in remission for ALL.
