Previous studies demonstrated a decreased flow reserve in the hypertrophied myocardium early after myocardial infarction (MI). Previously, we reported that exacerbation of hemodynamic abnormalities and neurohumoral activation during exercise caused slight impairment of myocardial O(2) supply in swine with a recent MI. We hypothesized that increased metabolic coronary vasodilation [via ATP-sensi...
BACKGROUND Live animal markets have been implicated in transmission of influenza A viruses (IAVs) from animals to people. We sought to characterize IAVs at 2 live animal markets in Minnesota to assess potential routes of occupational exposure and risk for interspecies transmission. METHODS We implemented surveillance for IAVs among employees, swine, and environment (air and surfaces) during a...
BACKGROUND Triple-reassortant (tr) viruses of human, avian, and swine origin, including H1N1, H1N2, and H3N2 subtypes, emerged in North American swine herds in 1998 and have become predominant. While sporadic human infections with classical influenza A (H1N1) and with tr-swine influenza viruses have been reported, relatively few have been documented in occupationally exposed swine workers (SW)....
Reproductive failure in swine is often a difficult diagnostic problem. If diagnoses of infectious disease or management related problems are not obtained, feed quality and safety may be questioned. Mycotoxins are often present in swine feed in the amount that can have detrimental impact on production and reproduction. Problems are expressed only as alterations of the reproductive cycle, reduced...
2. Swine pyloric juice also exhibited two proteolytic pH maxima, at pH values 1-6 and 2-6, which are lower than those of swine or human fundic extracts or of human gastric juice. 3. Crystalline swine pepsin can be separated into two components, one of which digested proteins with pH maxima close to those found with swine fundic mucosa and the other with maxima close to those found with pyloric ...
R ECENT reports (Baker et al., 1967a, b) indicate anabolic activity from orally-administered diethy, lstilbestrol plus methvltestosterone for finishing swine, particularly at adequate to superadequate levels of dietary protein. Because fat deposition was shown to be influenced by the hormonal combination, by sex and by dietary protein level, components of the serum lipid fraction were evaluated...
Japanese encephalitis virus (JEV) is a mosquito-borne, zoonotic flavivirus causing viral encephalitis in humans and reproductive disorder in swine. JEV is prevalent throughout China in human; however, spatiotemporal analysis of JEV in Chinese swine herds has not been reported previously. Herein, we present serological and molecular epidemiological results and estimates of prevalence of JEV infe...
BACKGROUND Differentiated human airway epithelial cell cultures have been utilized to investigate cystic fibrosis, wound healing, and characteristics of viral infections. These cultures, grown at an air-liquid interface (ALI) in media with defined hormones and growth factors, recapitulate many aspects of the in vivo respiratory tract and allow for experimental studies at the cellular level. O...
Feral swine populations are expanding throughout the U.S., where they are causing increasing amounts of damage to agriculture, natural resources, and property and threaten human health and safety. Methods to control feral swine damage in the U.S. consist of integrated fencing, trapping, snaring, and shooting (including hunting with dogs) efforts. New methods that are being developed to control ...
Populations of feral swine (Sus scrofa) are estimated to include >2 million animals in the state of Texas, USA, alone. Feral swine damage to property, crops, and livestock exceeds $50 million annually. These figures do not include the increased risks and costs associated with the potential for feral swine to spread disease to domestic livestock. Thus, effective bio-security measures will be nee...
