| O objetivo deste trabalho foi avaliar a fitossociologia de plantas daninhas em cafezais sob diferentes períodos de consórcio com leguminosas em dois anos de cultivo. Os tratamentos corresponderam à combinação fatorial entre as leguminosas feijão-de-porco (Canavalia ensiformis) e lablabe (Dolichos lab-lab) e períodos de consorciação com cafeeiros aos 30, 60, 90 e 120 dias após o plantio, mais uma testemunha sem leguminosa. O experimento foi composto por nove tratamentos em delineamento de blocos casualizados com quatro repetições. As leguminosas foram semeadas em dezembro de 2007 e outubro de 2008 e cortadas conforme os períodos de consorciação, sendo removidas da entrelinha, para ficarem sob a copa dos cafeeiros. As plantas daninhas foram amostradas nas... |

| To assess the clinical relevance of a semi-quantitative measurement of human cytomegalovirus (HCMV) DNA in renal transplant recipients within the typical clinical context of a developing country where virtually 100% of both receptors and donors are seropositive for this virus, we have undertaken HCMV DNA quantification using a simple, semi-quantitative, limiting dilution polymerase chain reaction (PCR). We evaluated this assay prospectively in 52 renal transplant patients from whom a total of 495 serial blood samples were collected. The samples scored HCMV positive by qualitative PCR had the levels of HCMV DNA determined by end-point dilution-PCR. All patients were HCMV DNA positive during the monitoring period and a diagnosis of symptomatic infection was... |

| Hypomagnesemia is the most common electrolyte disturbance seen upon admission to the intensive care unit (ICU). Reliable predictors of its occurrence are not described. The objective of this prospective study was to determine factors predictive of hypomagnesemia upon admission to the ICU. In a single tertiary cancer center, 226 patients with different diagnoses upon entering were studied. Hypomagnesemia was defined by serum levels <1.5 mg/dl. Demographic data, type of cancer, cause of admission, previous history of arrhythmia, cardiovascular disease, renal failure, drug administration (particularly diuretics, antiarrhythmics, chemotherapy and platinum compounds), previous nutrition intake and presence of hypovolemia were recorded for each patient. Blood... |
