(1) 5-Azacytidine (I) stability was increased approximately 10-fold over its stability in water or lactated Ringer injection by the addition of excess sodium bisulfite and the maintenance of pH approximately 2.5.
(2) Since the advance and return of sperm inside the tubes could facilitate the interaction of sperm with secretions participating in its maturation, the persistent infertility after vasectomy could be related to the contractile alteration that follows the excessive tubal distention.
(3) The following conclusions emerge: (i) when the 3' or the 3' penultimate base of the oligonucleotide mismatched an allele, no amplification product could be detected; (ii) when the mismatches were 3 and 4 bases from the 3' end of the primer, differential amplification was still observed, but only at certain concentrations of magnesium chloride; (iii) the mismatched allele can be detected in the presence of a 40-fold excess of the matched allele; (iv) primers as short as 13 nucleotides were effective; and (v) the specificity of the amplification could be overwhelmed by greatly increasing the concentration of target DNA.
(4) Excessive lip protrusion was eliminated, and arch leveled.
(5) Ten milliliters of the solution inappropriately came into contact with nasal mucous membranes, causing excessive drug absorption.
(6) Dietary factors affect intestinal P450s markedly--iron restriction rapidly decreased intestinal P450 to beneath detectable values; selenium deficiency acted similarly but was less effective; Brussels sprouts increased intestinal AHH activity 9.8-fold, ECOD activity 3.2-fold, and P450 1.9-fold; fried meat and dietary fat significantly increased intestinal EROD activity; a vitamin A-deficient diet increased, and a vitamin A-rich diet decreased intestinal P450 activities; and excess cholesterol in the diet increased intestinal P450 activity.
(7) Cigarette consumption has also been greater in urban areas, but it is difficult to estimate how much of the excess it can account for.
(8) Preliminary studies of different systems suggest several of them may have sensitivity to detect intraepithelial abnormalities in excess of 95%.
(9) Excessive accumulation of hydrogen ions in the brain may play a pivotal role in initiating the necrosis seen in infarction and following hyperglycemic augmentation of ischemic brain damage.
(10) Fifty-four cases were analysed, and a two-fold excess of clustering within one year was observed, both within single districts and between adjacent districts.
(11) The first one is a region with iodine insufficiency; the second one is a region where the people use table salt in excess.
(12) Addition of methacholine to the substance-P-treated cells caused a rapid increase in [3H]IP3, whereas a second addition of a 10-fold excess of substance P had no effect.
(13) It is possible that the marked elevations in obsessive-compulsive symptomatology and in interpersonal sensitivity may reflect in part a sensitization to excessive performance demands.
(14) Using the intersection point of these pH-logPCO2 lines as a point of equal hemoglobin-independent "base excess" for each condition, values for true base excess were plotted.
(15) This excess in diagnosis comprises, in particular, the ductal type, primarily its most aggressive forms.
(16) Attention is drawn to the desirability of differentiating between supra- and sub-gingival calculus in the CPITN scoring system and to the excessive treatment requirements that arise from classifying everyone with calculus as requiring prophylaxis and scaling.
(17) IgG-gold also adhered to M cells and excess unlabeled IgG inhibited IgA-gold binding; thus binding was not isotype-specific.
(18) The technique did not compromise cancer resection, excessively prolong operating time, or alter postoperative management.
(19) The temperature-activated 4 to 5 S EBP transformation is found to be highly reproducible without loss of [3H]estradiol-binding activity in a buffer containing an excess of [3H]estradiol, 40 mM Tris, 1 mM dithiothreitol, and 1 M urea at pH 7.4.
(20) The amount of cleavage products depends on the excess of H2O2 used.
