(4) Several histidine derivatives are not susceptible to the enzyme but do inhibit the enzyme activity competitively; the most effective inhibitors are L-histidine methyl ester (Ki = 3.66 mM) and beta-imidazole lactic acid (Ki = 3.84 mM).
(5) Radioactive lactic acid was detected in the drained perfusion solution with D(U-14C)-glucose, but not when D(U-14C)-fructose was used.
(6) We examined the effect of lactic acid on cultured human glioma cell lines expressing glial fibrillary acidic protein (GFAP), vimentin and neuron-specific enolase (NSE).
(7) With the aid of analysis of afferent impulse activity in the cat chorda tympani, it was shown that the effect of application of organic acids solutions of the same pH to the tongue could be represented as follows: propionic acid greater than lactic acid greater than pyruvic acid.
(8) Isolated urinary bladder strips were prepared from bladder base and body and the following metabolic determinations were made: glucose utilization, glycogen formation, CO2, and lactic acid formation.
(9) Preretinal pulsatile pressure juxtaarteriolar microinjections of neutral-pH solution of L-lactic acid also induced a segmental retinal arteriolar dilation.
(10) They analysed vascular resistance on the foetal side of the placenta, glucose consumption, production of lactic acid and pyruvic acid.
(11) Since hypoglycemia was associated with acidosis, the severe lactic acidosis in our patient may have been due to an overproduction of lactic acid as well as to an impaired hepatic gluconeogenesis in the presence of leukemic cells.
(12) Rumen pH decrease to below 5.0 in S2-, lasalocid-, and monensin-treated cattle was not due to lactic acid, but to increased production of volatile fatty acids.
(13) An autopsy case of mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is reported.
(14) It is possible that cell walls may be involved in the binding of mutagenic pyrolyzates to lactic acid bacteria.
(15) Ventilation (VE) and arterial pH were measured at rest and during exercise before and after infusions of lactic acid (70 meq), HCl (26 meq), NaHCO3 (45 and 90 meq), or normal saline alone (250 ml).
(16) Central nervous system (CNS) cultured neurons while exposed to different concentrations and pH of L-lactic acid exhibited in general chromatin clumping, vacuolization in the cytoplasm, appearance of lipid bodies, accumulation of polyribosomes, cytoplasmic lucency and swollen and aggregation of mitochondria.
(17) The severity of lactic acidosis in critically ill patients correlates with overall oxygen debt and survival.
(18) This increase of lactic acid persists 24 hours after the induction of infarction.
(19) In vitro exposure of rat thymocytes to arecoline resulted in a biphasic oxygen consumption response with progressive increase in oxygen consumption, reaching a maximum value at 10(-5) M and decreasing sharply at 10(-3) M. Exogenously added substrates such as glucose, pyruvic acid and lactic acid retarded the fall in the oxygen consumption induced at 10(-3) M arecoline.
(20) Glycolic acid and 3-(4-hydroxyphenyl)-lactic acid were the specific substrates for MLO-I and MLO-II, respectively.
Lactim
Definition:
(n.) One of a series of anhydrides resembling the lactams, but of an imido type; as, isatine is a lactim. Cf. Lactam.
Example Sentences:
(1) A possible solution to this potential problem by the use of the new Polysorb-Lactimer absorbable TA55 stapler is presented.
(2) By means of a molecular orbital method which considers all valence electrons, INDO, we have calculated several electronic indices and determined the major tautomers in the lactan-lactim tautomerism of alloxan in the liquid and gaseous states.
(3) With all other compounds no tautomeric forms other than the lactams could be detected, although small proportions of bilirubin must exist as the lactim.
(4) The compounds crystallize as the lactams, except for dimethoxybilirubin dimethyl ester and its phenylazo derivative, which are held in the lactim ether configuration.
(5) Correlating these with the NMR spectra in the -10 ppm to -11 ppm region allows us to conclude that the "GU pairs" are not hydrogen-bonded by tautomerization to the lactim form.
(6) studies also suggest that bilirubin dimethyl ester is in the lactam rather than the lactim form.
