Clinical profile of dengue hemorrhagic fever cases in Mexico. With four serotypes circulating the risk of epidemic dengue hemorrhagic fever is increasing. Clinical picture and epidemiological features were compared and a multivariate model was fitted to evaluate associations. RESULTS: Cases were divided into two groups: patients with dengue fever, including cases with hemorrhagic manifestations without thrombocytopenia, and cases with dengue hemorrhagic fever, including 79 deaths. The main risk factors associated with mortality were hematemesis RR 2.

It has also been proven that plant and AMF symbiosis benefits from auxin aplication to roots. The present study had the objective to determine if plant-hormone interaction occurred with hormone groups other than auxins.
Mycorrhizal and nonmycorrhizal Carrizo citrange Citrus sinensis L. GA 3 treated seedlings had a bigger trunk diameter but the treatment did not increase seedling height, dry weight, leaf number and leaf area per plant. GA 3 treatment also resulted in increased levels of P and Fe in the leaves, reduced K leaf contents but had no effect on other nutrients and did not affect root colonization by AMF. Key words: endomycorrhizal fungi, citrus, growth regulators. Em outubro, avaliou-se o desenvolvimento vegetativo das plantas.

A number of transport proteins are vesiculzres in the process of intestinal cholesterol absorption and might provide links to increased biliary cholesterol supersaturation. Key words Gastrointestinal motility, smooth muscle, cholesterol crystals, gallbladder motility. Recent studies indicate that the intestine also plays an important role in pathogenesis of cholesterol gallstones, if one considers several factors. Sign in via OpenAthens.

Parasitism of Rhizoctonia solani by strains of Trichoderma spp. Parasitismo de Rhizoctonia solani por linhagens de Trichoderma spp. Directory of Open Access Journals Sweden. Full Text Available Rhizoctonia solani causes serious diseases in a wide range of plant species. The fungus Trichoderma has been shown to be particularly effective in the control of the pathogen. Thus, this research was carried out to screen fourteen Trichoderma strains against R. All strains tested inhibited the growth of R.
