Cytokine Production By Blue Tongue Virus-Infected Fetal Sheep Cells, F. M. Enright, B. I. Osburn Jan 1979

Cytokine Production By Blue Tongue Virus-Infected Fetal Sheep Cells, F. M. Enright, B. I. Osburn

Faculty Publications

The migration inhibition of guinea pig peritoneal macrophages by a factor(s) from media obtained from blue tongue virus-infected monolayer cultures was studied. Medium from blue tongue virus-infected sheep fetal cell cultures inhibited migration of guinea pig macrophages from agarose droplets. Medium from control cultures and stock virus did not inhibit macrophage migration. Medium containing migration inhibiting factor(s) in vitro induced an inflammatory reaction in the skin of a newborn sheep. The inflammatory reaction was observed 20 h after intradermal inoculation. The skin reaction consisted of infiltrates of mononuclear leukocytes in the superficial dermis. Control medium and stock virus caused no …


Hatchability Of Bobwhite Quail Eggs Incubated In Various Temperature Combinations., H. R. Wilson, W. G. Nesbeth, E. R. Miller, T. B. Ande, D. R. Ingram Jan 1979

Hatchability Of Bobwhite Quail Eggs Incubated In Various Temperature Combinations., H. R. Wilson, W. G. Nesbeth, E. R. Miller, T. B. Ande, D. R. Ingram

Faculty Publications

Five experiments were conducted to compare the effects of various incubation temperature combinations on the hatchability of Bobwhite quail eggs. A starting incubation temperature of 40.6 C resulted in numerically lower hatchability. Incubation at 37.5 C resulted in a greater number of pipped, unhatched eggs, and a later, less uniform hatch. Temperatures during the hatching period (22 to 25 days of incubation) of 36.9 C and 38.1 C resulted in lower hatchability than the hatching temperature of 37.5 C.


An Experimental Analysis Of The Effects Of D‐Amphetamine And Cocaine On The Acquisition And Performance Of Response Chains In Monkeys, Donald M. Thompson, Joseph M. Moerschbaecher Jan 1979

An Experimental Analysis Of The Effects Of D‐Amphetamine And Cocaine On The Acquisition And Performance Of Response Chains In Monkeys, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

In one component of a multiple schedule of food presentation, monkeys acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four geometric forms (learning). In the other component, the four‐response chain was the same each session (performance). Both d‐amphetamine and cocaine, at the higher doses, disrupted the behavior in the learning component; the overall response rate decreased, the overall accuracy was impaired (i.e., percent errors increased), and there was less within‐session error reduction. The performance component was generally less sensitive than the learning component to the disruptive effects of both drugs on …


Effects Of Methamphetamine And Scopolamine On Variability Of Response Location, Joseph M. Moerschbaecher, Donald M. Thompson, John R. Thomas Jan 1979

Effects Of Methamphetamine And Scopolamine On Variability Of Response Location, Joseph M. Moerschbaecher, Donald M. Thompson, John R. Thomas

Faculty Publications

Methamphetamine and scopolamine were studied in monkeys responding under a multiple fixed‐ratio fixed‐interval schedule of reinforcement. A response on any one of six levers could satisfy the schedule requirements. Variability of response location was evaluated in terms of switches, where a switch was defined as a response on one lever followed by a response on a different lever. Under baseline conditions the fixed‐ratio schedule generated a high rate of responding and a low level of variability, while the fixed‐interval schedule generated a low rate of responding and a high level of variability. Both methamphetamine (0.1 to 0.5 mg/kg) and scopolamine …


Effect Of Testosterone And Estradiol-17Β Alone And In Combination On Lh And Fsh Concentrations In Blood Serum And Pituitary Of Geldings And In Serum After Administration Of Gnrh, D. L. Thompson, B. W. Pickett, E. L. Squires, T. M. Nett Jan 1979

Effect Of Testosterone And Estradiol-17Β Alone And In Combination On Lh And Fsh Concentrations In Blood Serum And Pituitary Of Geldings And In Serum After Administration Of Gnrh, D. L. Thompson, B. W. Pickett, E. L. Squires, T. M. Nett

Faculty Publications

16 stallions were castrated and 30 days later assigned to 1 of 4 treatments: testosterone propionate (T, 175 μg/kg BW), estradiol-17β-3-benzoate (E, 44 μg/kg BW), the combination of both steroids (TE) or control (safflower oil). These dosages were administered every other day for 18 days (low dose) and then were doubled (high dose). Treatment at the high dose was continued for 27 days and the geldings were sacrificed. Treatment at the low dose resulted in concentrations of testosterone and estradiol in serum similar to those in intact stallions during the breeding season. Concentrations of LH and FSH in peripheral serum …

Variability In 24-Hour Urine Sodium Excretion In Children, Kiang Liu, Richard Cooper, Ivan Soltero, Jeremiah Stamler Jan 1979

Variability In 24-Hour Urine Sodium Excretion In Children, Kiang Liu, Richard Cooper, Ivan Soltero, Jeremiah Stamler

Faculty Publications

How many 24-hour urine sodium measurements are adequate for characterizing a child's salt intake? Can overnight urine specimens accurately replace 24-hour collections for salt assessment? A sample of 73 6tb-8th grade children was taken from two parochial schools in Chicago to inrestigate systematically these questions. Seven consecutive 24-hour-urine specimens were collected from each child. The estimated ratio of intra- to inter-individual variances was 1.94 for 24-hour-urine sodium. Based on this value, eight 24-hour specimens are necessary to limit to 10% the diminution of the estimated correlation coefficient between 24- hour-urine sodium and blood pressure. Six measurements are required to reduce …


Can Overnight Urine Replace 24-Hour Urine Collection To Assess Salt Intake?, Kiang Liu, Alan R. Dyer, Richard S. Cooper, Rose Stamler, Jeremiah Stamler Jan 1979

Can Overnight Urine Replace 24-Hour Urine Collection To Assess Salt Intake?, Kiang Liu, Alan R. Dyer, Richard S. Cooper, Rose Stamler, Jeremiah Stamler

Faculty Publications

Are overnight urine specimens adequate for characterizing the daily salt intake of individuals, i.e., can the overnight specimen replace the 24-bour specimen? Data from 142 male participants of an ongoing trial on the primary prevention of hypertension were used to examine this question with correlation analysis and quantile classification. Estimated correlation between the true mean 24-hour and the true mean overnight sodium excretion was 0.72. Furthermore, 67% of the individuals in the upper third of the distribution of true mean overnight urine sodium were also in the upper third of the distribution of true mean 24-hour sodium. Thus, these data …

On A Theorem Of Murasug, C. Gordon, R. A. Litherland Jan 1979

On A Theorem Of Murasug, C. Gordon, R. A. Litherland

Faculty Publications

Let l=k1⋃k2be a 2-component link in S3with k2unknotted. The 2-fold cover of S3branched over k2is again S8; let k1(2) be the inverse image of k1and suppose that k1(2) is connected. How are the signatures σ(k1), σ(K1)(2) of the knots k1and K1(2)related? This question was considered (from a slightly different point of view) by Murasugi, who gave the following answer [Topology, 9 (1970), 283-298]. © 1979, University of California, Berkeley.

On A Packing Problem For Infinite Graphs And Independence Spaces, James G. Oxley Jan 1979

On A Packing Problem For Infinite Graphs And Independence Spaces, James G. Oxley

Faculty Publications

In this paper several infinite extensions of the well-known results for packing bases in finite matroids are considered. A counterexample is given to a conjecture of Nash-Williams on edge-disjoint spanning trees of countable graphs, and a sufficient condition is proved for the packing problem in independence spaces over a countably infinite set. © 1979.
