Comparative studies were made of the metabolic activities of a strain of Staphylococcus aureus grown in iron-poor and iron-rich trypticase medium, with and without glucose. Four nutritionally distinctive types of organisms were produced : iron-rich without glucose (Fe + G ) ; ironpoor without glucose (Fe G ) ; iron-rich with glucose (Fe + G + ) ; iron-poor with glucose (FeG + ) . Fe+ G cocci ox...

The direct oxidative dehydrogenation of lactates with molecular oxygen is a "greener" alternative for producing pyruvates. Here we report a one-pot synthesis of mesoporous vanadia-titania (VTN), acting as highly efficient and recyclable catalysts for the conversion of ethyl lactate to ethyl pyruvate. These VTN materials feature high surface areas, large pore volumes, and high densities of isola...

Assuming that the oxidation of alcohol runs parallelly with the other metabolic process in hepatic cells, further investigations of alcoholemia aimed at finding distemper exponents in NADH and NADPH coenzyme reoxidation, and secondarily in behaviour of hydrogen accepting substrates (1,2,3) should be undertaken. These products take part in coenzyme reoxidation as carriers retransporting H ions f...

Match-lay demands of Gaelic football and fitness profiles were assessed at club competitive level. English Gaelic football club championship players (n = 11) were assessed for anthropometry, leg strength and time to exhaustion on a treadmill run. A similar test battery was administered to a reference group of University competitive soccer players (n = 12). Heart rate was recorded during match-p...

INTRODUCTION To evaluate the strength of association between lactic acidosis (LA) and well-recognized risk factors for LA, particularly the weight of metformin. METHODS This study is a matched case-control analysis concerning the type 2 diabetes population from Grenoble Hospital University. Cases of LA were defined biologically with pH < 7.35 and lactates > 5 mmol/L. They were matched to 2 co...

OBJECTIVE To compare the haemodynamic effect of crystalloids and colloids during acute severe hypovolaemic shock. DESIGN Exploratory subgroup analysis of a multicentre randomised controlled trial (Colloids Versus Crystalloids for the Resuscitation of the Critically Ill, CRISTAL, ClinicalTrials.gov NCT00318942). SETTING CRISTAL was conducted in intensive care units in Europe, North Africa an...

To the Editor, Sim et al. should be congratulated for their meticulous analysis of a large and complete dataset following patients with acute myocardial infarction for more than 2 years. They concluded from propensity score analyses that statins were associated with decreased in-hospital mortality and 12-month adverse cardiac events. Their conclusions are debatable. First, the inclusion criteri...

Mthough a vasodilator drug might favorably alter hemoynamics in resting, supine patients with heart failure, It must be determined If the drug has any unfavorable as well as favorable effects under extremes of real life sfress situations normally encountered by ambulatory patients, especially upright exercise. An adverse response might occur with the addition of pharmacologic vasodilatlon to th...

BACKGROUND/AIMS The modified early warning score (MEWS) is used to predict patient intensive care unit (ICU) admission and mortality. Lactate (LA) in the blood lactate (BLA) is measured to evaluate disease severity and treatment efficacy in patients with severe sepsis/septic shock. The usefulness of a combination of MEWS and BLA to predict ICU transfer in severe sepsis/septic shock patients is ...
