Acute exposure to low concentrations of methylmercury (MeHg) causes a severe loss of intracellular calcium (Ca2+(i)) homeostasis, which apparently contributes to neuronal death of cerebellar granule cells in culture. We examined the role of muscarinic receptors in MeHg-induced Ca2+ dysregulation and cell death in rat cerebellar granule cells in vitro using(More)
Burkholderia pseudomallei, the etiologic agent of melioidosis, is a gram-negative facultative intracellular bacterium. This bacterium is endemic in Southeast Asia and Northern Australia and can infect humans and animals by several routes. It has also been estimated to present a considerable risk as a potential biothreat agent. There are currently no(More)
Twenty-seven mammary tumors from 18 male (3 intact, 15 neutered) dogs were collected. The average age at diagnosis was 9.2 years (range, 2-14 years). Seven of the dogs were Cocker Spaniels. Five dogs had multiple mammary tumors. All tumors were benign. Twenty-six were simple adenomas with mixed acinar and papillary patterns. The acinar pattern was(More)
Primary sclerosing cholangitis is a chronic and progressive cholestatic liver disease that has been extensively documented in the human literature. Although it shares many features in common with chronic lymphocytic cholangitis in cats, primary sclerosing cholangitis has never been reported in a nonhuman primate. Primary sclerosing cholangitis is(More)
The objective was to use an animal model to study different types of interposition grafts for rectovaginal fistula repair. Twelve New Zealand white rabbits underwent surgical creation of a rectovaginal fistula, followed by repair. Four repair techniques were studied; three with interposition grafts and one control group without a graft. Animals were(More)
Recent experimentation with the variants of the Ebola virus that differ in the glycoprotein's poly-uridine site, which dictates the form of glycoprotein produced through a transcriptional stutter, has resulted in questions regarding the pathogenicity and lethality of the stocks used to develop products currently undergoing human clinical trials to combat(More)
Ebola virus (EBOV) persistence in asymptomatic humans and Ebola virus disease (EVD) sequelae have emerged as significant public health concerns since the 2013-2016 EVD outbreak in Western Africa. Until now, studying how EBOV disseminates into and persists in immune-privileged sites was impossible due to the absence of a suitable animal model. Here, we(More)
Lassa virus (LASV) infection causes an acute, multisystemic viral hemorrhagic fever that annually infects an estimated 100 000 to 300 000 persons in West Africa. This pathogenesis study evaluated the temporal progression of disease in guinea pigs following aerosol and subcutaneous inoculation of the Josiah strain of LASV as well as the usefulness of Strain(More)
Burkholderia pseudomallei, the etiologic agent of melioidosis, is a Gram negative bacterium designated as a Tier 1 threat. This bacterium is known to be endemic in Southeast Asia and Northern Australia and can infect humans and animals by several routes. Inhalational melioidosis has been associated with monsoonal rains in endemic areas and is also a(More)
The purpose of this study was to histologically chronicle wound healing following cystotomy repair using a small animal model. Thirty female Sprague–Dawley rats were included in this study. Twenty-eight rats underwent a vertical cystotomy in the bladder dome, which was repaired in a single continuous fashion. Two rats served as histological controls.(More)
