Safety, pharmacokinetics, and pharmacodynamics of RSLV-132, an RNase-Fc fusion protein in systemic lupus erythematosus: a randomized, double-blind, placebo-controlled study.

Blood-borne RNA circulating in association with autoantibodies is a potent stimulator of interferon production and immune system activation. RSLV-132 is a novel fully human biologic Fc fusion protein that is comprised of human RNase fused to the Fc domain of human IgG1. The drug is designed to remain in circulation and digest extracellular RNA with the aim of preventing activation of the immune system via Toll-like receptors and the interferon pathway.

All That Swells Is Not A Bruise The Morel-Lavallée Lesion.

Frequently overlooked, Morel-Lavallée lesions are associated with a closed degloving or shearing mechanism causing a dehiscence of underlying soft tissue with formation of a potential space. This space fills with blood, lymph, and cellular debris, giving the lesion a fluctuant appearance on examination. The potential space associated with larger lesions can be a source for hemorrhage in the appropriate clinical context.

A woman with dyspnea and hemoptysis.

A 55-year-old female presented to the emergency department at a small community hospital with cough, fever, dyspnea and blood-streaked sputum. A chest radiograph was ordered. She was diagnosed with pneumonia and discharged home with antibiotics.

Kif11 dependent cell cycle progression in radial glial cells is required for proper neurogenesis in the zebrafish neural tube.

Radial glia serve as the resident neural stem cells in the embryonic vertebrate nervous system, and their proliferation must be tightly regulated to generate the correct number of neuronal and glial cell progeny in the neural tube. During a forward genetic screen, we recently identified a zebrafish mutant in the kif11 loci that displayed a significant increase in radial glial cell bodies at the ventricular zone of the spinal cord. Kif11, also known as Eg5, is a kinesin-related, plus-end directed motor protein responsible for stabilizing and separating the bipolar mitotic spindle.

Maternal prepregnancy overweight and offspring fatness and blood pressure: role of physical activity.

The purpose of this study was to examine if offspring physical activity may affect the relationship between maternal overweight and offspring fatness and blood pressure (BP). Subjects included 144 maternal-child pairs (n = 74 boys and 70 girls, mean age = 7.3 yrs).
