coli isolates. Our report suggests that E.coli can cause severe skin or soft tissue infection in the postoperative course of liver transplantation. The onset of infection is very early and the outcome is extremely poor, despite prompt adapted medical and surgical treatment. Host factors, rather than E.coli bacterial virulence potential, appear to be the major determinants of severity in these patients.”
“Alzheimer’s

disease is the most common cause of senile dementia in the United States and Europe. At present, there is no effective treatment. Given the disease’s prevalence and poor prognosis, the development of animal models has been a high research priority. Transgenic modeling has been selleck products pursued oil the basis of the amyloid hypothesis and has taken advantage Of mutations in the amyloid precursor protein and the presenilins that cause familial forms of Alzheimer’s disease. Modeling has been most aggressively pursued in mice, for which the techniques of genetic modification are well developed Transgenic mouse models now exist that mimic a range of Alzheimer’s disease-related p pathologies. Although CX-6258 mouse none of the models fully replicates the human disease, the models have contributed significant insights into the pathophysiology of beta-amyloid toxicity, particularly

with respect to the effects of: different beta-amyloid species and the possible pathogenic role of beta-amyloid oligomers. They have also been widely used in the preclinical testing of potential therapeutic modalities and have played a pivotal role in the development of immunotherapies for Alzheimer’s disease that are currently

ill clinical trials. These models Will, without a doubt, continue to Play central roles in preclinical testing and be used as tools for developing insights into the biological basis of Alzheimer’s disease. Mt Sinai J Med 77:69-81, 2010. (C) 2010 Mount Sinai School of Medicine”
“Dental caries is an infectious disease that causes tooth decay. The high prevalence of dental caries in recent humans is attributed to more frequent consumption of plant foods rich in fermentable carbohydrates in food-producing societies. The transition from hunting Cell Cycle inhibitor and gathering to food production is associated with a change in the composition of the oral microbiota and broadly coincides with the estimated timing of a demographic expansion in Streptococcus mutans, a causative agent of human dental caries. Here we present evidence linking a high prevalence of caries to reliance on highly cariogenic wild plant foods in Pleistocene hunter-gatherers from North Africa, predating other high caries populations and the first signs of food production by several thousand years. Archaeological deposits at Grotte des Pigeons in Morocco document extensive evidence for human occupation during the Middle Stone Age and Later Stone Age (Iberomaurusian), and incorporate numerous human burials representing the earliest known cemetery in the Maghreb.
