The incidence of colorectal cancer (CRC) in China is lower than that in the west countries, but has increased in recent years and become a substantial cancer burden in China, particularly in the more developed areas. Some studies have reported changes in the characteristics of CRC in China. However, due to a lack of an effective nation-wide surveillance system, there has been little information available on the relationship between CRC and geographical environment and economic status in China.

Alcoholic liver disease (ALD) is the most common cause of liver cirrhosis in the Western world. Liver biopsy is currently considered the gold standard for assessing hepatic fibrosis or cirrhosis in these patients. However, it is an invasive procedure, with rare but potentially life-threatening complications and its accuracy is limited due to sampling error. Transient elastography (FibroScan®, FS) is a novel rapid and noninvasive method to assess liver fibrosis via measurement of liver stiffness (LS).

Proton pump inhibitors (PPIs) are the most effective agents for treating acid related gastrointestinal (GI) disorders. The utilization of intravenous (IV) formulations of PPIs has dramatically increased in health care institutions for inappropriate indications, route of administration and length of treatment. This is associated with an increased cost burden, increased risk of IV related infections, and utilization of hospital resources.

Nifedipine, a calcium-channel blocker, was shown to decrease lower esophageal sphincter pressure and increase esophageal acid exposure time, while atenolol, a b1 blocker, was shown to inhibit relaxation of the smooth muscle of the esophagus. However, the influence of these anti-hypertensive drugs on the segment of esophageal body contraction using high-resolution manometry was not fully investigated.

It is generally recommended that a temporary stoma be closed within 9-12 wk after its construction. However, because some patients poorly tolerate the temporary stoma owing to extracellular dehydration, difficult pouch fitting, parenteral nutrition requirement in cases when the stoma is very proximal, and psychological or social impact, it might be advisable to opt for early closure.

Gastric varices (GV) are an important complication of portal hypertension. As an almost atraumatic method, computed tomography (CT) angiography has been used widely to show the portal vein system. However, the collateral circulation of GV in different locations has been reported only rarely.

Personal health recommendations and diets tailored to better prevent diseases may be in our future, just by focusing on genetics.

Researchers at Kansas State University recently published an academic journal article discussing the potential for nutrigenomics, a field that studies the effects of food on gene expression. The researchers discussed the possibility of using food to prevent an individual's genes from expressing disease. The researchers said nutrigenomics could completely change the future of public health and the food and culinary industries.

An Agricultural Research Service (ARS) scientist is helping to sort through the jumbled genetics of Echinacea, the coneflower known for its blossoms--and its potential for treating infections, inflammation, and other human ailments.

The occurrence of gluten intolerance in the Finnish population has doubled in the past twenty years. In the early 1980s, about one per cent of adults in Finland had gluten intolerance, but the figure has since gone up to two per cent by the 2000s.

Liver transplantation specialists recently convened to address U.S. guidelines for allocation of organs for patients with hepatocellular carcinoma (HCC, liver cancer). Representatives from more than 130 U.S. transplant centers were invited to the conference and participants included 180 leaders in liver transplantation (LT) from the 50 most active centers. Full details of the recommendations developed at the conference are published in the March issue of Liver Transplantation, a journal of the American Association for the Study of Liver Diseases (AASLD).

Singapore: Singaporeans consume around 275,000 tons of rice each year, which requires 688 billion liters of water to be produced – 2.5 times Singapore's annual domestic water use.

Competition for water is getting fiercer and water supplies are dwindling, yet Singapore can contribute to securing its rice supply by joining the global community in helping farmers become water-wise.

Washington, DC, USA – Previous studies have explored the effect of periodontal treatment, irrespective of efficacy of treatment, in reducing infant prematurity. In a study titled "Risk of Preterm Birth Is Reduced with Successful Periodontal Treatment," lead researcher M. Jeffcott, and colleagues S. Parry and M. Sammel (all from the University of Pennsylvania, Philadelphia) and G. Macones (Washington University, St. Louis, Missouri) determined whether a reduction in infant prematurity was associated with successful periodontal treatment.

Washington, DC, USA – Today, during the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, DC, lead researcher O.A. Gonzalez (University of Kentucky, Lexington) will present a poster of a study titled "TLR2 and TLR9 Activation by Periodontal Pathogens induce HIV-1 Reactivation." Although oral co-infections (e.g.

Recent years have seen an unusual rise in the number of bees about in the cold winter months, and scientists are now beginning to find out why.

While most bees are hibernating, the buff-tailed bumblebee, Bombus terrestris, is out taking advantage of exotic winter-flowering plants in our gardens and parks, according to scientists from Queen Mary, University of London.

People who are stressed by daily problems or trouble at work seem to be more likely to grind their teeth at night. Researchers writing in BioMed Central's open access journal Head & Face Medicine studied the causes of 'sleep bruxism', gnashing teeth during the night, finding that it was especially common in those who try to cope with stress by escaping from difficult situations.
