INTRODUCTION Critically ill surgical patients frequently develop intra-abdominal hypertension (IAH) leading to abdominal compartment syndrome (ACS) with subsequent high mortality. We compared two temporary abdominal closure systems (Bogota bag and vacuum-assisted closure (VAC) device) in intra-abdominal pressure (IAP) control. METHODS This prospective study with a historical control included ...

Cardiac lymph in dogs was used to study the metabolism and state of the myocardium during extracorporeal circulation and various additional procedures. Changes in the flow characteristics, cdor and pH of lymph were noted, and corresponding samples of cardiac lymph and coronary sinus blood were analyzed for lactate concenlmtion. Ventricular fibrillation led to higher lactate levek when compared ...

Increased plasma nitrate concentrations from dietary sources of nitrate have proven to benefit exercise performance. Beetroot (BR) contains relatively high levels of nitrate (NO₃⁻), which increases nitric oxide stores. This study investigated whether dietary nitrate supplementation, in the form of a BR beverage, would improve rowing performance during ergometer repetitions. In a randomized cros...

In their recent article in CHEST (January 2014) on the treatment of acute asthma with albuterol, Lewis et al 1 show that high levels of lactate during such treatment are highly prevalent; in addition, high plasma albuterol concentration is signifi cantly correlated with hyperlactatemia. In a previous case involving a woman with asthma, we described lactic acidosis (pH 7.29) and a high level of ...

We evaluated: the agreement between lactate minimum and maximal lactate steady state (MLSS) cycling powers (study 1); whether rates of change of blood lactate concentration during the lactate minimum test reflect that of constant power exercise (study 2); whether the lactate minimum power is influenced by the muscle groups used to elevate blood lactate concentration (study 3). Study 1: 32 subje...

Pseudomonas putida PP3 grew on DL-2-monochloropropionate (2MCPA) with a release of chloride ions consistent with the dechlorination of both isomers. The organism grew on either D- or L-2MCPA. Dehalogenase activity in cell-free extracts showed that both D- and L-2MCPA were dehalogenated. Pseudomonas putida PP3 contains two dehalogenases, and studies with the separated enzymes revealed that the f...

Hierarchical zeolites containing tin were obtained, characterized and used in a reaction of catalytic isomerization of dihydroxyacetone (DHA) to lactic acid and alkyl lactates. These catalysts are characterized by preserved crystallinity and primary microporosity with the simultaneous existence of secondary porosity regarding mesopores, which facilitates access of large molecules of reagents to...
