In this paper, we present an in-depth study of a non-invasive method to determine the bulk modulus of microgel particles. The method relies on measuring the particle size as a function of external osmotic pressure using dynamic light scattering to measure the particle size and dextran solutions to change the osmotic pressure. An independent characterization of the dynamic response of the dextran solutions is required in order to obtain the microgel size in the microgel/dextran mixtures. The method works fine in most cases except for slightly crosslinked microgels, where the scattering from the particles is comparable to the scattering from the dextrans. [ABSTRACT FROM AUTHOR]

This article is a brief review of the clinical, radiographic, and pathologic features of Pick disease. It is directed toward residents and fellows in training as well as practicing physicians who might wish to find a concise treatise on this clinicopathologic entity. The pathogenesis and genetics of this disorder are discussed. Included are medical journal articles accessed from computerized medical literature searches of articles published in the last 10 years. Pertinent images have been included where necessary. Although ubiquitously discussed in medical school and residency, Pick disease is nevertheless a relatively uncommon clinicopathologic entity. Recognition of its clinical and pathologic manifestations is critical in correctly diagnosing this illness and subsequently educating family members of the deceased. [ABSTRACT FROM AUTHOR]

A male patient with distant history of extensive rabbit contact and pulmonary nodules for 6 years developed empyema. Francisella tularensis holarctica was isolated from thoracentesis fluid. Retrospective immunohistochemical examination of a pulmonary nodule, biopsied 3 years prior, was immunoreactive for F. tularensis. These findings suggest the potential for chronic tularemia.

The article presents the findings of study conducted by Douglas County Health Department (DCHD) and Nebraska Department of Health and Human Services (NDHHS) into the outbreak of histoplasmosis among attendees of a city day camp, organized on June 2012, in Nebraska. It explains histoplasmosis and its symptoms and transmission. It discusses the methodology used in the investigation and testing histoplasma. It informs that the health departments also offer suggestions to city parks and recreation division regarding preserving their sites from bat roosting, biohazardous contamination.

The article discusses the findings of an investigation conducted by the Douglas County Health Department (DCHD) in Omaha, Nebraska and the Nebraska Department of Health and Human Services (NDHHS) into the extent and source of histoplasmosis outbreak among day camp attendees in Nebraska on June 21, 2012. The common fungal infection is reportedly the cause of respiratory illness outbreaks in endemic areas in the U.S. Symptoms of histoplasmosis include fever, headache and respiratory symptoms.
