(Lippincott Williams and Wilkins, 2009)Background: Rotavirus and more recently norovirus have been recognized as 2 of the most common causes of acute diarrhea in children. Comparative analysis of these infections in a birth cohort has not been performed and can ...
-
(2009)Background: PCR has evolved into one of the most promising tools for T. cruzi detection in the diagnosis and control of Chagas disease. However, general use of the technique is hampered by its complexity and the lack of ...
-
(2009)Background: Cold storage is used to inhibit peach fruit ripening during shipment to distant markets. However, this cold storage can negatively affect the quality of the fruit when it is ripened, resulting in disorders ...

-
(2009)Vascular calcification is caused by the deposition of basic calcium phosphate crystals in blood vessels, myocardium, and/or cardiac valves. Calcification decreases artery wall compliance, and arterial calcification is ...
-
(2009)Peer methodology (PM) is an adaptation of the privileged access interviewer methodology and is used for prevalence studies. PM estimates higher drug consumption frequencies among school and college students than self ...

-
(2009)Background: Patients with type 2 diabetes have a high incidence of coronary artery disease, which is even higher among those with renal failure. Serum levels of cystatin C are used to assess renal function and is a potential ...
-
(Sociedad de Biologia de Chile, 2009)It is well known that the number of plant species associated with nurse plants increases with elevation. However, studies conducted so far have largely ignored the effect of nurse plants on other community attributes, such ...
