The oxidation of CH2O in the intermediate temperature range (943-995 K)

New atmospheric pressure flow reactor data on the oxidation of formaldehyde in the temperature range 943-995 K and over equivalence ratios from 0.013 to 36.7 are reported and discussed. A detailed mechanism assembled from previously published results produced acceptable agreement with the experimental data for the fuel-lean conditions, but failed to predict results for oxidative pyrolysis. Analysis or the very fuel-lean conditions, but failed to modelling results are principally sensitive to CH2O+HO2→HCO+H2O2 (6) and H2O2 +M→OH+OH+M (33). Whereas the specific rate of each reaction cannot be independently determined, it is found that the product k33.k6 is a well defined function of temperature: (3.4±3.0).1028 exp(-(26,800±400)/T). Inadequacies in the mechanism which may be responsible for the disagreement under fuel-rich conditions are discussed. © 1991 Combustion Institute.

Intersexualidad y derecho: análisis del concepto género en las sentencias de asignación de sexo (Análisis de las sentencias: T-477 de 1.995, SU-337 de 1.999, T-551 de 1.999, T-692 de 1.999, T-1390 de 2.000, T-1025 de 2.002, T-1021 de 2.003 y T-912 de 2.008)

Esta monografía estudia 8 casos de menores de edad intersexuales que han sido fallados por la Corte Constitucional. A partir de las discertaciones jurídicas hechas por los magistrados se pueden encontrar interesantes elementos para el estudio del concepto género y la postura que frente al mismo ha tomado la Corte en su jurisprudencia.

Preventive effects of octreotide (SMS 201-995) on diabetic ketogenesis during insulin withdrawal

1. Exogenous somatostatin inhibits glucagon secretion and prevents ketoacidosis in diabetic patients, but has the therapeutic disadvantage of requiring continuous intravenous infusion to exhibit these effects. 2. Consequently, we examined the effect of subcutaneous administration of the long-acting somatostatin analogue octreotide (SMS 201-995) on early ketogenesis in diabetic ketoacidosis. On two separate occasions insulin was withdrawn over a period of 9 h from seven type I diabetic patients. On the second occasion the patients were given 50 micrograms octreotide s.c. before the insulin withdrawal and every 3 h during insulin withdrawal. 3. Differences in integrated free fatty acid responses (4706 +/- 1227 mumol l-1 h vs 3026 +/- 835 mumol l-1 h, AUC, P = NS) were not significant, but the peak increments of acetoacetate (1413 +/- 354 mumol l-1 vs 612 +/- 176 mumol l-1, P less than 0.05), beta-hydroxybutyrate (2180 +/- 475 mumol l-1 vs 922 +/- 246 mumol l-1, P less than 0.01) and the decrements in plasma bicarbonate (-8 +/- 1 mumol l-1 vs -4 +/- 1 mumol l-1, P less than 0.05) and pH (-0.07 +/- 0.01 vs -0.03 +/- 0.01, P less than 0.05) were significantly less with octreotide. 4. At the same time peak increments of glucagon were lower with octreotide treatment (329 +/- 206 pg ml-1 vs 39 +/- 30 pg ml-1, P less than 0.05). 5. We conclude that, despite accelerated lipolysis and provision of substrate for ketogenesis during insulin withdrawal, this somatostatin analogue significantly reduces ketogenesis resulting from insulin deprivation, probably secondary to decreasing glucagon secretion. This drug may be useful in short term prophylactic treatment of diabetic patients during periods of increased risk for ketoacidosis.
