he success of the Human Genome Project and the powerful tools of molecular biology have ushered in a new era of medicine and nutrition. An emerging discipline, known as nutrigenomics, which allows the relationship between diet, genetics and disease to be delineated, looks set to transform clinical pet nutrition. In this article, Professor John Innes, from the University of Liverpool, evaluates the implications of nutrigenomics on pet health and takes a closer look at how this exciting technology is already being used to alleviate some of the symptoms of canine osteoarthritis (OA).  相似文献

一提到滇藏线,很多人立即想起了214国道.事实上.214国道是从青海的西宁到云南的景洪,全长3296公里.而人们通常说的滇藏线,只是214国道的一部分——从云南大理到西藏芒康这一段,共700多公里. 在滇藏线沿线,不仅能看到各种优美的景色,如:丽江、澜沧江峡谷、金沙江大拐弯、梅里雪山、盐井的盐田等;也可以体会到独特丰富的地域文化和民族风情,沿途会经过苗族、白族、纳西族和藏族等多个少数民族地区.2012年5月,我们一行4人从云南大理开始了滇藏线的骑行之旅.  相似文献

Food associated viruses are responsible for a high number of infectious diseases in man, mainly gastroenteritis and hepatitis. The three most important viral agents are noroviruses (NV) (formerly known as Norwalk-like viruses), Rotavirus (RV) and Hepatitis A-Virus (HAV). The numbers of infections in man were in 2002 according to the Robert Koch-Institut for NV and RV 50,000, respectively, and for HAV 1,500, slightly decreasing in 2003. The rate of foodborne infections caused by viruses can only be estimated (appr. 20% of total cases). On the other hand only a very small part of viral gastroenteritis can be diagnosed and notified. Besides the direct infection through contaminated food the human to human infection is the most important source, also responsible for outbreaks. There is at the moment no routine diagnostic tool available for the detection of viruses in food because of the lack of standardized methods. For NV, one of the most important foodborne (live bivalve molluscs) viral pathogens, indicator organisms are in use. There is a scientific evaluation in different member states concerning the value of bacterial indicators vs. bacteriophages. In addition to foodborne viruses (via faecal contamination present in the food chain) there are emerging zoonotic viral agents. Food may be a vector for this agents depending on the production structures (e.g. SARS or influenca).  相似文献

Scientists, researchers, and their findings are critical factors in helping to resolve contemporary societal problems. Because of the tremendous interconnectivity of our lives and the expanded scope and scale of the medical and health problems we face, the research community needs to be both more involved and more competent in the development of public policy and to become more effective participants in the political and media activities in which their work is firmly embedded. This article suggests that researchers and scientists will be more relevant, have more impact, and be more productive if they can blend outstanding science with new non-cognitive skills that can reinforce the important social context of their work.  相似文献

Agricultural expansion and intensification are having a huge impact on plant and arthropod diversity and abundance, affecting food availability for farmland birds. Difficult food access, in turn, can lead to immunosuppression and a higher incidence of parasites. In the studies designed to examine changes in the diet of birds and their parasites, metabarcoding is proving particularly useful. This technique requires mini-barcodes capable of amplifying the DNA of target organisms from fecal environmental DNA. To help to understand the impact of agricultural expansion on biodiversity, this study sought to design and identify mini-barcodes that might simultaneously assess diet and intestinal parasites from the feces of farmland birds. The capacity to identify diet and parasites of 2 existing and 3 newly developed mini-barcodes was tested “in silico” in relation to the behavior of a reference eukaryotic barcode. Among the newly designed mini-barcodes, MiniB18S_81 showed the higher taxonomic coverage of eukaryotic taxa and a greater amplification and identification capacity for diet and parasite taxa. Moreover, when it was tested on fecal samples from 5 different steppe bird species, MiniB18S_81 showed high taxonomic resolution of the most relevant diet and parasite phyla, Arthropoda, Nematoda, Platyhelminthes, and Apicomplexa at the order level. Thus, the mini-barcode developed emerges as an excellent tool to simultaneously provide detailed information regarding the diet and parasites of birds, essential for conservation and management.  相似文献

Glanders is the contagious zoonotic disease caused by infection with Burkholderia mallei. It affects primarily horses, donkeys and mules. The disease was eradicated from large areas of the Western world in the early 20th century, but, over the last 10–20 years, has emerged and re‐emerged in areas in which it was previously unknown or had been eradicated. Although glanders was previously thought to manifest in only acute or chronic presentations, it now appears that B. mallei can produce latent infections similar to those caused by Burkholderia pseudomallei. These latent infections may or may not be detectable by current diagnostic tests. The diagnostic test currently recommended by the World Organisation for Animal Health (Office International des Epizooties [OIE]) for international trade in equids is the complement fixation test (CFT). This test has been shown to have varying sensitivities and specificities depending on the antigen and methodology used. False positives are problematic for the horse‐owner and veterinary authority, whereas false negatives may allow the reintroduction of B. mallei into B. mallei‐free areas. These gaps in knowledge of the epidemiology of glanders, and weaknesses in its diagnosis, coupled with the increased movement of equids, indicate that infection with B. mallei remains a major risk in the context of international movement of equids.  相似文献

The rete ovarii of cattle may be morphologically divided into the intraovarian rete, the connecting rete, and the extraovarian rete. The connecting rete may be subdivided into that portion which lies within the ovary proper and that portion that lies in the mesovarium. The portion of the connecting rete which lies in the mesovarium is connected to the infundibulum of the uterine tube by a patent tubo-retial communication.
Mitotic figures were observed in the epithelial cells of the rete ovarii during estrus, during metestrus, following superovulation, and in association with the cystadenomatous change which was observed in one ovary of an estrus cow. The epithelial lining of microcysts appeared to proliferate and produce material which filled the cysts. The occurrence of vesicles in the retial epithelium appeared more commonly during diestrus and gestation. The greatest amount of cells, cellular debris and amorphous luminal material was observed during anestrus, diestrus and gestation.  相似文献
