Inflammatory bowel diseases, including ulcerative colitis and Crohn's disease, increase the risk of colorectal cancer in humans. It has been recently shown in humans and animal models that intestinal microbiota and host immunity are integral in the progression of large bowel diseases. Lymphocytes are widely believed to prevent bacterially induced(More)
It is generally agreed that most colon cancers develop from adenomatous polyps, and it is this fact on which screening strategies are based. Although there is overwhelming evidence to link intrinsic genetic lesions with the formation of these preneoplastic lesions, recent data suggest that the tumor stromal environment also plays an essential role in this(More)
Roles for host immune response in carcinogenesis are not well defined. Recent studies have shown that microbially driven inflammation can lead to colon cancer and that prior transfer of regulatory lymphocytes expressing CD4 and CD25 prevents the innate inflammatory events that lead to colon cancer in mice. To further examine the ability of regulatory(More)
BACKGROUND AND PURPOSE Hepatic encephalopathy is a neuropsychiatric disorder of complex pathogenesis caused by acute or chronic liver failure. We investigated the effects of cannabidiol, a non-psychoactive constituent of Cannabis sativa with anti-inflammatory properties that activates the 5-hydroxytryptamine receptor 5-HT(1A) , on brain and liver functions(More)
PURPOSE omega 3 polyunsaturated fatty acids have anti-inflammatory properties and can be beneficial in the treatment of inflammatory diseases, such as ulcerative colitis. Dextran sodium sulphate (DSS) colitis in rats appears to mimic nearly all of the morphological characteristics and lesion distributions of ulcerative colitis. The purpose of the current(More)
Wound healing capability is inextricably linked with diverse aspects of physical fitness ranging from recovery after minor injuries and surgery to diabetes and some types of cancer. Impact of the microbiome upon the mammalian wound healing process is poorly understood. We discover that supplementing the gut microbiome with lactic acid microbes in drinking(More)
Maedi-visna virus (MVV) in sheep, which infects mainly cells of the monocyte/macrophage lineage, produces changes in the lung, mammary gland, brain and joints. In this study, however, the liver and heart of six naturally infected sheep were examined for the presence of the virus. MVV proviral DNA was demonstrated by polymerase chain reaction (PCR) analysis,(More)
An unusual papillary meningioma in a cat with progressive cerebellar ataxia is described. Computed tomography revealed the presence of a primary tumour. Microscopically, the tumour was seen to arise from the cerebellar pia mater, forming perivascular structures composed of a single layer of cuboidal to columnar epithelial cells. By immunolabelling, the(More)
The decline of circulating testosterone levels in aging men is associated with adverse health effects. During studies of probiotic bacteria and obesity, we discovered that male mice routinely consuming purified lactic acid bacteria originally isolated from human milk had larger testicles and increased serum testosterone levels compared to their age-matched(More)
Radiant skin and hair are universally recognized as indications of good health. However, this 'glow of health' display remains poorly understood. We found that feeding of probiotic bacteria to aged mice induced integumentary changes mimicking peak health and reproductive fitness characteristic of much younger animals. Eating probiotic yogurt triggered(More)
