Clinical and epidemiology evaluation of Aids-infected patients hospitalized between 2011 and 2016 in the Santos region of Brazil.

Introduction: We assessed the clinical-epidemiological profile of acquired immune deficiency syndrome (AIDS) patients in the Santos region (São Paulo state) with the highest AIDS prevalence in Brazil.

Methods: Information was extracted from records of 409 AIDS-infected patients hospitalized between 2011 and 2016.

Results: Human immunodeficiency virus (HIV) was diagnosed in 24.

Effect of soil storage at 4 °C on the calorespirometric measurements of soil microbial metabolism.

Soil samples must usually be stored for a time between collection and measurements of microbial metabolic properties. However, little is known about the influence of storage conditions on microbial metabolism when studied by calorespirometry. Calorespirometry measures the heat rate and the CO rate of microbial metabolism, where the ratio of heat and CO released, the calorespirometric ratio, informs about the nature of substrates being used by microorganisms.

Calculation of the specific rate of catabolic activity (Ac) from the heat flow rate of soil microbial reactions measured by calorimetry: significance and applications.

The calculation of parameters involved in the kinetics of the microbial soil reactions linked to the carbon cycle is strongly limited by the methodologies employed. Hence, a mathematical model is proposed to quantify easily the specific rate of catabolic activity A(c) by microcalorimetry based on Belaich's model. It permits to quantify A(c) from the plots of the heat flow rate vs.

A combined mass and energy balance to provide bioindicators of soil microbiological quality.

In this work, a method is proposed to quantify the efficiency of carbon utilization by soil microbes. Microcalorimetry was used to compute the heat yield (Y(Q/X)) of six soil samples collected in the Amazon. A combined mass and energy balance is developed to quantify the enthalpy of the glucose oxidation reaction (Delta(r)H(s)) and the biomass yield (Y(X/S)) from the experimental values of Y(Q/X).
