Understanding longitudinal trends in the processing of carbon in rivers represents a much conceptualised, but infrequently tested, issue in aquatic ecology. In this study, we conducted concurrent longitudinal examinations of three very different rivers in eastern Australia to determine whether general principles in river functioning exist across broad geographic and hydrologic scales. Specifica...

The effect of pyridine homologues on proton leakage, respiratory control, oxidative phosphorylation, and H+/O ratio in mitochondria have been examined. Up to a concentration of 1 mM, hydrophobic pyridine homologues diminish respiratory control in bovine heart mitochondria by increasing the State 4 respiration rate but have relatively minor effects on the State 3 and the 2,4-dinitrophenol-uncoup...

BACKGROUND The NNRTI efavirenz is among the most widely employed antiretroviral drugs. Although it is considered safe, efavirenz has been linked with several adverse effects including neurological manifestations, which appear in the majority of the patients on efavirenz-containing regimens. The molecular mechanisms responsible for these manifestations are not understood, but mounting evidence p...

Heart failure remains a major public-health problem with an increase in the number of patients worsening from this disease. Despite current medical therapy, the condition still has a poor prognosis. Heart failure is complex but mitochondrial dysfunction seems to be an important target to improve cardiac function directly. Our goal was to analyze the effects of MitoQ (100 µM in drinking water) o...

BACKGROUND Propionic acidaemia (PA) results from deficiency of Propionyl CoA carboxylase, the commonest form presenting in the neonatal period. Despite best current management, PA is associated with severe neurological sequelae, in particular movement disorders resulting from basal ganglia infarction, although the pathogenesis remains poorly understood. The role of liver transplantation remains...

Soil microbiological indicators are essential tools to understand how the management with cover crops interferes in activity and soil microbial community. Thus, objective of study was evaluate attributes performance bacterial community Brazilian Cerrado different crops. The experiment performed a randomized block design, evaluating seven crops, Sorghum bicolor, Crotalaria ochroleuca, Pennisetum...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

In animals, longevity (maximal lifespan) is inversely related to mass-specific basal metabolic rates. However, contrary to expectation, in several mammalian taxa, exceptional longevity is associated with high basal metabolic rate, and also fast evolution of mtDNA-coded proteins. The association of these traits was suggested to result from adaptive selection of mutations in mtDNA-coded proteins,...

This article explores a technique for measuring the energy (NEL) value of feeds without respiration calorimetry or slaughter. The objectives were to compare results obtained from goats with those from cows, and to describe factors which limited the precision of these NEL estimates. One lactating Alpine doe and one lactateing Holstein cow were assigned to each of six different sequences of three...
