| alanine metabolism in skeletal muscle in tissue culture. | alanine production by skeletal muscle in tissue culture was studied using an established myogenic line (l6) of rat skeletal muscle cells. correlation analyses were performed on rates of metabolism of alanine, glucose, lactate and pyruvate over incubation periods up to 96 h. alanine production did not correlate significantly with glucose utilization (r = 0.24, p less than 0.20). alanine production, however, did correlate with lactate production (r = 0.72, p less than 0.0005) as well as medium (r ... | 1979 | 444590 |

| distribution of iron between the binding sites of transferrin in serum: methods and results in normal human subjects. | when it is incompletely saturated with iron, transferrin may exist in four molecular forms: apotransferrin, monoferric (a) transferrin (with iron occupying only the a site of the protein), monoferric (b) transferrin, and diferric transferrin. by combining electrophoresis in urea-polyacrylamide gels with crossed immunoelectrophoresis using specific antihuman transferin antiserum, it is possible to display and estimate the concentration of each of these four forms in normal human serum. the distri ... | 1979 | 444649 |

| sensitivity of gentamicin-resistant enterobacteriaceae to cefamandole and cefoxitin. | a collection of gentamicin-resistant enterobacteriaceae strains was significantly more resistant to cefamandole than a species-matched collection of gentamicin-sensitive organisms. cefamandole and gentamicin resistance could be simultaneously transferred by conjugation from four different species, citrobacter freundii, escherichia coli, klebsiella pneumoniae and serratia marcescens, to a recipient e. coli strain. plasmids specifying linked resistance to cefamandole and gentamicin are thus common ... | 1979 | 456076 |
| specific vs nonspecific factors in psychotherapy. a controlled study of outcome. | this study explored the relative contribution of the therapist's technical skills and the qualities inherent in any good human relationship to outcome in time-limited individual psychotherapy. highly experienced psychotherapists treated 15 patients drawn from a relatively homogeneous patient population (male college students, selected primarily on the basis of elevations on the depression, anxiety, and social introversion scales of the minnesota multiphasic personality inventory). by traditional ... | 1979 | 475546 |
| partial trisomy for the long arm of chromosome 7 due to familial balanced translocation. | a partial trisomy for the distal segment of the long arm of chromosome 7 (bands q32 replaced by qter) was observed in a severely retarded child with somatic and cns anomalies. the phenotypically normal father and paternal grandmother had a balanced reciprocal translocation between the long arm of a chromosome 2 and the long arm of a chromosome 7: 46,xx-xy,t(2;7) (q37;q32). the clinical features of the child at birth and at the ages of 5 months and 2 years are compared with those previously repor ... | 1979 | 478537 |

| in vitro activity of ly127935. | the activity of ly127935, a beta-lactam antibiotic of novel structure, was studied in vitro against facultative gram-negative bacilli, staphylococcus aureus, and bacteroides fragilis. the strains were recent clinical isolates, many of which were relatively resistant to other antibiotics. ly127935 exhibited striking activity against escherichia coli, klebsiella pneumoniae, enterobacter sp., proteus sp., serratia marcescens, and b. fragilis with median minimum inhibitory concentrations of less tha ... | 1979 | 507785 |
| a nuclear precursor to human gamma-globin messenger rna. | rna isolated from human foetal liver at an erythroid stage of development was transferred from methyl mercury hydroxide agarose gels to diazobenzyloxymethyl paper. a 16s rna species containing gamma-globin mrna sequences was identified by hybridisation to 32p-labelled human gamma-globin cdna recombinant plasmid phgamma gi. this rna is found only in the cell nucleus and is polyadenylated. human globin gene transcription is thus analagous to that in mouse: interventing sequences are transcribed an ... | 1979 | 514808 |
| inhibition of drug oxidation and stimulation of nadph oxidase in vitro by doxorubicin and triferric-doxorubicin. | the electrophilic properties of the quinone-hydroquinone configuration of anthracycline antibiotics suggests a possible influence on cytochrome p-450-mediated mono-oxygenase reactions. both doxorubicin and triferric-doxorubicin (a derivative in which the quinone groups are blocked with iron) showed a similar dose-dependent inhibition of liver microsomal drug metabolism. a doxorubicin concentration-related stimulation of nadph oxidase activity was found to be linear but that for triferric-doxorub ... | 1979 | 515168 |
| spinal analgesia and sedation of goats with lignocaine and xylazine. | spinal anaesthesia of 20 does undergoing laparotomies was accomplished with epidural injections of 2 per cent lignocaine at a dosage of 1 ml per 4.55 kg in 16 goats. epidural injection resulted in paralysis lasting 198.5 minutes +/- 36.6 minutes. subarachnlid injection resulted in paralysis lasting 180.8 minutes +/- 44.9 minutes. xylazine was given intramuscularly at the dosage of 0.11 mg per kg after posterior paralysis was complete. these treatments resulted in effective analgesia for surgical ... | 1979 | 516312 |

| ceftizoxime (fk 749), a new parenteral cephalosporin: in vitro and in vivo antibacterial activities. | fk 749 is a new parenteral cephalosporin derivative which is more active against various gram-negative bacilli, including the opportunistic pathogens such as enterobacter, citrobacter species, and serratia marcescens, than cephalosporins and cephamycins such as cefotiam, cefamandole, cefuroxime, cefotaxime, and cefmetazole. fk 749 was especially active against gram-negative organisms resistant to these related antibiotics. fk 749 was more potent in bactericidal activity than the other antibiotic ... | 1979 | 525994 |
| ly127935, a new beta-lactam antibiotic, versus proteus, klebsiella, serratia, and pseudomonas. | one hundred eight clinical isolates of proteus, klebsiella, serratia, and pseudomonas spp. were tested in vitro against ly127935, cefamandole, cefoxitin, ticarcillin, carbenicillin, gentamicin, tobramycin, and amikacin by broth microdilution. the activities of ly127935 were greater than or equal to those of the other antimicrobial agents against proteus vulgaris, klebsiella pneumoniae, and serratia marcescens. inhibitions were greatest, however, for ticarcillin and carbenicillin versus proteus m ... | 1979 | 526006 |
| lateral interactions in human cone dark adaptation. | 1. the course of cone dark adaptation after exposure to a strong bleaching light depends on the size of the bleached region. threshold for brief, tiny test flash centred in the bleached region is elevated more, and recovery is retarded by a small bleach. this effect has its parallel in the sensitization effect observed with steady backgrounds. 2. previous results, that a similar sensitization effect is not observed in rod dark adaptation, are confirmed. 3. this sensitization effect in cone dark ... | 1979 | 529074 |

| fortimicin a: collaborative in vitro susceptibility. comparison with amikacin and gentamicin against 11,840 clinical bacterial isolates. | the susceptibility of 11,840 clinical bacterial isolates to fortimicin a was determined by agar dilution or broth microdilution methods and compared with their susceptibility to amikacin and gentamicin. in general, the in vitro activity of fortimicin a was essentially the same as that of amikacin. significant exceptions were the increased effectiveness of fortimicin a against serratia marcescens and the greater activity of amikacin against pseudomonas and other nonfermentative gram-negative baci ... | 1979 | 533262 |
| in vitro activity of ly127935, a new 1-oxa cephalosporin, against aerobic gram-negative bacilli. | a total of 434 clinical aerobic gram-negative bacillary isolates were tested against ly127935, a new 1-oxa cephalosporin, and compared with other cephalosporins, penicillins, and aminoglycosides by a broth microdilution technique. cefotaxime (hr756), a new semisynthetic cephalosporin, and ly127935 were more active, and showed lower minimum inhibitory concentrations (ranges, less than or equal to 0.12 to 2.0 micrograms/ml), than cefamandole, cefoxitin, and cefazolin against escherichia coli, kleb ... | 1979 | 533267 |
