(1) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
(2) Work on humoral responses has focused on lysozyme, the hemagglutinins (especially in the oyster), and the clearance of certain antigens.
(3) Stress is laid on certain principles of diagnostic research in the event of extra-suprarenal pheochromocytomas.
(4) As a group, the three mammalian proteins resemble bovine serum conglutinin and behave as lectins with rather broad sugar specificities directed at certain non-reducing terminal N-acetylglucosamine, mannose, glucose and fucose residues, but with subtle differences in fine specificities.
(5) A segment of vas deferens was transplanted to the contralateral deferens with the intention of improving treatment for certain cases of infertility caused by obstruction.
(6) hypoglossal nucleus), whereas in other areas the angiotensinogen gene was expressed only in a certain population of glial cells.
(7) 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.
(8) Certainly, Saunders did not land a single blow that threatened to stop his opponent, although he took quite a few himself that threatened his titles in the final few rounds.
(9) We present a mathematical model that is suitable to reconcile this apparent contradiction in the interpretation of the epidemiological data: the observed parallel time series for the spread of AIDS in groups with different risk of infection can be realized by computer simulation, if one assumes that the outbreak of full-blown AIDS only occurs if HIV and a certain infectious coagent (cofactor) CO are present.
(10) HDAra-C in combination with anthracyclines is now considered to be a treatment which may afford some hope of a cure in a certain percentage of cases of adult acute non-lymphocytic leukemia.
(11) These results suggest that a certain minimum level of expression of c-myc is required for the maintenance of ras transformation in NIH 3T3 cells.
(12) This "paradox of redistribution" was certainly observable in Britain, where Welfare retained its status as one of the 20th century's most exalted creations, even while those claiming benefits were treated with ever greater contempt.
(13) In certain cases, the effects of these substances are enhanced, in others, they are inhibited by compounds that were isolated from natural sources or prepared by chemical synthesis.
(14) Accumulating evidence indicates that for most tumors, the switch to the angiogenic phenotype depends upon the outcome of a balance between angiogenic stimulators and angiogenic inhibitors, both of which may be produced by tumor cells and perhaps by certain host cells.
(15) The findings indicate that these spaces were lined by a lipid monolayer which formed bilayered lamellae under certain conditions.
(16) Positive feedback effects on serum gonadotrophins in castrates were observed following injection of certain doses of some steroids.
(17) Hence, presence of IgG rheumatoid factor correlated positively with the presence of rheumatoid disease, and evidence was established that certain features of rheumatoid inflammation occur in dental periapical lesions of many patients with rheumatoid disease.
(18) The typology developed in two previous surveys of illicit heroin products is applicable to many of the samples studied in this work, although significant changes have occurred in the chemical profile of illicit heroin products from certain geographical regions.
(19) The presence of an inverse correlation between certain tryptophan metabolites, shown previously to be bladder carcinogens, and the N-nitrosamine content, especially after loading, was interpreted in view of the possible conversion of some tryptophan metabolites into N-nitrosamines either under endovesical conditions or during the execution of the colorimetric determination of these compounds.
(20) An electrogenic sodium-potassium pump appears to contribute materially to the steady-state potential and to certain of the transient potential responses of vascular smooth muscle.
Should
Definition:
(imp.) of Shall
(imp.) Used as an auxiliary verb, to express a conditional or contingent act or state, or as a supposition of an actual fact; also, to express moral obligation (see Shall); e. g.: they should have come last week; if I should go; I should think you could go.
