The anomalies of enzyme action have frequently been accounted for by the assumption of an intermediate compound between the enzyme and the substrate. I t was shown, however, by Nelson and Hitchcock t that in the case of invertase the experiments could not be accurately calculated on this basis. The writer found with trypsin' that although the effect of varying the substrate concentration could ...

A biochemical approach was employed to examine the oxidative utilization of carbohydrate and lipid in red muscle of rainbow trout (Oncorhynchus mykiss) during sustained swimming at 30 and 60% of their critical swimming speed (U(crit); for 2, 15 and 240 min) and during non-sustainable swimming at 90% U(crit) (for 2, 15 and 45 min). Measurements included pyruvate dehydrogenase (PDH) activity, cre...

Following L-DOPA administration, DA metabolites were measured by both in vivo voltammetry and HPLC-ECD. In vivo, the amplitudes of the catechol oxidation currents in both the striatum and frontal cortex increased and reached a plateau from 60 min to 240 min after L-DOPA treatment. L-DOPA, DA, DOPAC and HVA levels measured by HPLC-ECD after L-DOPA treatment were increased in both regions, and th...

OBJECTIVE Uncomplicated, acute upper respiratory tract infections (URTIs) occur in patients with diabetes at a similar frequency to the general population. This study (NCT00642681) investigated the effect of URTIs on the pharmacokinetic (PK) and pharmacodynamic (PD) properties of Technosphere inhaled insulin (TI) in patients with type 1 or type 2 diabetes. RESEARCH DESIGN AND METHODS This was...

To determine the extent to which the hypertrophied left ventricle responds to the chronotropic stress induced by graded atrial pacing rates, we studied conscious, chronically instrumented dogs with severe compensated pressure overload left ventricular (LV) hypertrophy induced by aortic banding in puppies 8-10 weeks of age. At 1-2 years, dogs with severe LV hypertrophy (LV free wall/body wt rati...

BACKGROUND The pharmacokinetics of vaginal misoprostol as a dry tablet or as a tablet moistened with normal saline or with acetic acid were studied. METHODS For this study, 42 women requesting termination of pregnancy at gestational age of <12 weeks were recruited and received 400 µg vaginal misoprostol tablets. They were randomized into three groups: (i) dry tablets, (ii) tablets moistened w...

BACKGROUND A decrease in blood volume is thought to play a role in dialysis-related hypotension. Changes in relative blood volume (RBV) can be assessed by means of continuous haematocrit measurement. We studied the variability of RBV changes, and the relation between RBV and ultrafiltration volume (UV), blood pressure, heart rate, and inferior caval vein (ICV) diameter. METHODS In 10 patients...

A study of the metal inert gas welding MIG process was carried out in order to evaluate influence parameters on hardness and bending strength welded carbon steel plates. Welds were made by machine using different that include current 10-200 A, arc voltage 11-26.5 V, wire speed 1.5-16.5 m/min CO2 flow rate as 5-25 l/min. The result demonstrations increases with decreasing increasing current. Mor...
