Some large-sample distribution-free estimators and tests for multivariate partially incomplete data from two populations.

Statistics in medicine

Lachin JM.
PMID: 1509217
Stat Med. 1992 Jun 30;11(9):1151-70. doi: 10.1002/sim.4780110903.

The most common instance of multivariate observations is the case of repeated measures over time. The two most widely used methods for the analysis of K repeated measures for two groups are the K degrees of freedom (d.f.) T2...

Endocrine and ovarian responses associated with the first-wave dominant follicle in cattle.

Biology of reproduction

Badinga L, Driancourt MA, Savio JD, Wolfenson D, Drost M, De La Sota RL, Thatcher WW.
PMID: 1477213
Biol Reprod. 1992 Nov;47(5):871-83. doi: 10.1095/biolreprod47.5.871.

To examine endocrine and biochemical differences between dominant and subordinate follicles and how the dominant follicle affects the hypothalamic-pituitary-ovarian axis in Holstein cows, the ovary bearing the dominant follicle was unilaterally removed on Day 5 (n = 8), 8...

Prostate-specific antigen as a predictor of radiotherapy response and patterns of failure in localized prostate cancer.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology

Ritter MA, Messing EM, Shanahan TG, Potts S, Chappell RJ, Kinsella TJ.
PMID: 1378886
J Clin Oncol. 1992 Aug;10(8):1208-17. doi: 10.1200/JCO.1992.10.8.1208.

PURPOSE: A study of preradiation and postradiation, serial serum prostate-specific antigen (PSA) levels was performed in patients who had clinically localized prostate cancer. The prognostic value of the PSA in pretreatment evaluation and posttreatment follow-up was assessed.PATIENTS AND METHODS:...

Comparison of two cattle production systems in Pabna district Bangladesh.

Tropical animal health and production

Udo HM, Hermans C, Dawood F.
PMID: 2288009
Trop Anim Health Prod. 1990 Nov;22(4):247-59. doi: 10.1007/BF02240408.

In Pabna district, Bangladesh there are two cattle production systems: a draught-oriented system with local Deshi cattle and more milk-oriented production with Pabna Milking Cow (PMC) stock. Deshi animals are smaller than PMC animals. More PMC cows are milked...

Cost-effectiveness and obstetric services.

Medical care

Finkler MD, Wirtschafter DD.
PMID: 1921528
Med Care. 1991 Oct;29(10):951-63. doi: 10.1097/00005650-199110000-00002.

This study employs two risk-adjustment strategies to model the cost-effectiveness of obstetric services for eight hospitals in an urban health maintenance organization. Costs are adjusted by an index based on the expected length of a mother's stay, derived from...

Sister-chromatid exchange induction produced by in vivo and in vitro exposure to alpha-asarone.

Mutation research

Morales-Ramírez P, Madrigal-Bujaidar E, Mercader-Martínez J, Cassini M, González G, Chamorro-Cevallos G, Salazar-Jacobo M.
PMID: 1377782
Mutat Res. 1992 Jun 16;279(4):269-73. doi: 10.1016/0165-1218(92)90243-s.

The effect of alpha-asarone, a chemical with hypocholesterolemic properties extracted from Guatteria gaumeri, on SCE induction was studied both in human lymphocytes in vitro and in murine bone marrow cells in vivo. A slight but consistent increase in SCE...

Spectrofluorimetric study of the binding of 1-anilinonaphthalene-8-sulfonate to bovine serum albumin.

Journal of pharmaceutical sciences

Suárez Varela A, Sández Macho MI, Miñones J.
PMID: 1403732
J Pharm Sci. 1992 Aug;81(8):842-4. doi: 10.1002/jps.2600810825.

We studied the binding of the fluorescent probe 1-anilinonaphthalene-8- sulfonate to bovine serum albumin by spectrofluorimetric techniques. The binding of this probe to bovine serum albumin was via two types of sites: one with a high affinity constant but...

Characterization of ultra-high affinity monoclonal antibodies with a dimeric, symmetrical antigen: inhibition of the receptor recognition site of nerve growth factor.

Molecular immunology

Vroegop SM, Crumm E, Buxser SE.
PMID: 1313539
Mol Immunol. 1992 Mar;29(3):411-23. doi: 10.1016/0161-5890(92)90029-w.

We generated a family of ultra-high affinity monoclonal antibodies (MAb) which inhibit competitively the binding of nerve growth factor (NGF) to its receptor. Preliminary experiments indicated that the dissociation constants (Kd) of some of the MAb:NGF complexes were substantially...

Effects of breed and retained heterosis on milk yield and 200-day weight in advanced generations of composite populations of beef cattle.

Journal of animal science

Gregory KE, Cundiff LV, Koch RM.
PMID: 1506300
J Anim Sci. 1992 Aug;70(8):2366-72. doi: 10.2527/1992.7082366x.

Retained heterosis in F2 cows nursing F3 progeny was evaluated in 3-, 4-, and greater than or equal to 5-yr-old cows. Traits evaluated included milk yield at three stages of lactation and 200-d weight of progeny. Breed effects were...

Genetic analyses of growth, real-time ultrasound, carcass, and pork quality traits in Duroc and Landrace pigs: I. Breed effects.

Journal of animal science

Lo LL, McLaren DG, McKeith FK, Fernando RL, Novakofski J.
PMID: 1506301
J Anim Sci. 1992 Aug;70(8):2373-86. doi: 10.2527/1992.7082373x.

Knowledge of breed effects on carcass and pork quality traits is required to develop commercial crossbreeding programs that emphasize product quality. A 2 x 2 diallel mating system involving Landrace and Duroc pigs was used to estimate individual heterosis,...

Sex-linked and maternal effects on growth in chickens.

Poultry science

Barbato GF, Vasilatos-Younken R.

A study was designed to estimate the contribution of various types of genetic variation in growth of chickens using populations that widely differed in growth rate. Populations tested included a commercially developed sire line (CM), a fertility-selected, broiler-type line...

Recovery of inter-block information in cross-over trials.

Statistics in medicine

Chi EM.
PMID: 1876799
Stat Med. 1991 Jul;10(7):1115-22. doi: 10.1002/sim.4780100711.

For cross-over designs, we show that one can recover information on direct and/or residual treatment effects from an inter-block (patients as blocks) analysis as is done in an incomplete block design. By combining the intra- and inter-block estimates, we...
