Growth-stimulatory monoclonal antibodies against human insulin-like growth factor I receptor.

Proceedings of the National Academy of Sciences of the United States of America

Xiong L, Kasuya J, Li SL, Kato J, Fujita-Yamaguchi Y.
PMID: 1319060
Proc Natl Acad Sci U S A. 1992 Jun 15;89(12):5356-60. doi: 10.1073/pnas.89.12.5356.

Monoclonal antibodies (mAbs) against purified human placental insulin-like growth factor I (IGF-I) receptors were prepared and characterized. Three IgG mAbs were specific for the human IGF-I receptor and displayed negligible crossreactivity with the human insulin receptor. They stimulated 125I-labeled...

Liver uptake of amino acids and carbohydrates during a single circulatory passage.

The American journal of physiology

Pardridge WM, Jefferson LS.
PMID: 1130516
Am J Physiol. 1975 Apr;228(4):1155-61. doi: 10.1152/ajplegacy.1975.228.4.1155.

The uptake of 14C-labeled amino acids and carbohydrates by liver following rapid injection into the portal vein was measured relative to a simultaneously injected highly diffusible reference, tritium-labeled water, (3HOH). A 0.25-ml bolus of buffered Ringer solution containing 1-2...

The two-dimensional shape of spatial interaction zones in the parafovea.

Vision research

Toet A, Levi DM.
PMID: 1455707
Vision Res. 1992 Jul;32(7):1349-57. doi: 10.1016/0042-6989(92)90227-a.

The spatial analysis of a target may be strongly degraded by the simultaneous presentation of nearby pattern elements. The present study investigated the shape and extent of the region of interaction as a function of retinal location. The stimuli...

Partner-specific condom use among adolescent women clients of a family planning clinic.

The Journal of adolescent health : official publication of the Society for Adolescent Medicine

Plichta SB, Weisman CS, Nathanson CA, Ensminger ME, Robinson JC.
PMID: 1390818
J Adolesc Health. 1992 Sep;13(6):506-11. doi: 10.1016/1054-139x(92)90015-4.

Because inconsistent condom use could put adolescent women at an increased risk for sexually transmitted diseases, it is important to understand when and with whom they use condoms. This study examined partner-specific condom use over time among adolescent women....

Evolution in bacteria: evidence for a universal substitution rate in cellular genomes.

Journal of molecular evolution

Ochman H, Wilson AC.
PMID: 3125340
J Mol Evol. 1987;26(1):74-86. doi: 10.1007/BF02111283.

This paper constructs a temporal scale for bacterial evolution by tying ecological events that took place at known times in the geological past to specific branch points in the genealogical tree relating the 16S ribosomal RNAs of eubacteria, mitochondria,...

Release of antirenin to human renin by anaphylactic shock or by antihypertensive agents.

The American journal of physiology

Haas E, Goldblatt H, Lewis L, Klick RL.
PMID: 1130530
Am J Physiol. 1975 Apr;228(4):980-4. doi: 10.1152/ajplegacy.1975.228.4.980.

In dogs that have had repeated intravascular injections of small doses of human renin, even for long periods, the development of antirenin to human renin in the blood has not been previously noted, and their pressor response (30 mmHg)...

An intensity-dependent biphasic neuron in mudpuppy retina.

Vision research

Dong CJ, McReynolds JS.
PMID: 1455712
Vision Res. 1992 Aug;32(8):1405-8. doi: 10.1016/0042-6989(92)90195-o.

Intracellular recordings in dark-adapted mudpuppy retinas have revealed a type of infrequently encountered cell with unusual response properties. These cells may be a subclass of horizontal cell since they are encountered at the same depth as horizontal cells and...

Several nongenotoxic carcinogens uncouple mitochondrial oxidative phosphorylation.

Biochimica et biophysica acta

Keller BJ, Marsman DS, Popp JA, Thurman RG.
PMID: 1390825
Biochim Biophys Acta. 1992 Sep 25;1102(2):237-44. doi: 10.1016/0005-2728(92)90105-b.

A number of plasticizers and lipid-lowering drugs induce peroxisomes and cause hepatocellular carcinoma in rodents by mechanisms which remain unknown. In this study, seven structurally dissimilar peroxisome proliferating agents were shown to uncouple oxidative phosphorylation in isolated rat liver...

Pediatric surgical patients' and parents' stress responses and adjustment as a function of psychologic preparation and stress-point nursing care.

Nursing research

Wolfer JA, Visintainer MA.
PMID: 1101231
Nurs Res. 1975 Jul-Aug;24(4):244-55.

The purpose of this study was to test the hypotheses that children who receive systematic psychologic preparation and continued supportive care, in contrast to those who do not, would show less upset behavior and more cooperation in the hospital...

Vanadate mimics the effect of stem cell factor on highly purified human erythroid burst-forming units in vitro, but not the effect of erythropoietin.

Experimental hematology

Dai CH, Krantz S.
PMID: 1281783
Exp Hematol. 1992 Oct;20(9):1055-60.

When orthovanadate, an inhibitor of protein tyrosine phosphatase activity, was added to highly purified human blood erythroid burst-forming units (BFU-E) a marked increase in the number and size of erythroid bursts was evident at an optimum concentration of 4...

Redness from short-wavelength-sensitive cones does not induce greenness.

Vision research

Shevell SK.
PMID: 1455727
Vision Res. 1992 Aug;32(8):1551-6. doi: 10.1016/0042-6989(92)90210-a.

According to opponent-colors theory, a reddish surround induces greenness in a central test field. Color-appearance measurements verify this with a long-wavelength reddish surround (660 nm) but not with a short-wavelength reddish surround (440 nm). Surprisingly, a short-wavelength reddish surround...

Pediatric musculoskeletal tumors: use of dynamic, contrast-enhanced MR imaging to monitor response to chemotherapy.

Radiology

Fletcher BD, Hanna SL, Fairclough DL, Gronemeyer SA.
PMID: 1319075
Radiology. 1992 Jul;184(1):243-8. doi: 10.1148/radiology.184.1.1319075.

The ability of dynamic, gadolinium-enhanced magnetic resonance (MR) imaging to allow prediction of histologic responses to initial chemotherapy was evaluated in 20 patients with osteosarcoma (n = 12), Ewing sarcoma (n = 4), rhabdomyosarcoma (n = 3), or synovial...
