Neurotransmitter receptors in the suprachiasmatic nucleus: circadian and developmental studies

Description: The present audiographic study examined ligands for three receptors, chosen on the basis of high abundance of these receptors in the SCN relative to other brain regions([125I)VIP and [125I) angiotensin II) or the ability of pharmacological manipulations to affect the phase and period of circadian rhythms.

Moment variations: for orchestra and choir

Description: Moment Variations is a three-movement composition for chamber orchestra and chamber choir of approximately 21 minutes duration. The basis of this piece is compositional unity through variations technique, where the retained element of the theme is its structure or fixed-structure variations.The fixed-structure is a succession of six musical events, called moments, in the order: I II III II IV V III V VI, where moments II, III, and V are internally repeated and I, IV, and VI occur only once.

Arthur Garfield Dove's landscape assemblages: a unique intersection of European modernism, American ideas, and nature-based abstraction

Description: In the middle of his career, Arthur Garfield Dove created a smell yet novel body of landscape assemblages. They illustrate Dove's central interest in evoking nature--its motifs and rhythms--through imaginative associations of organic and man-made materials. These works represent Dove's synthesis of contemporary European stylistic and intellectual ideas as well as American philosophies and concerns. They also reflect the influence of Alfred Stieglitz and his circle and the artist Helen Torr, Dov… more

Evidence for a Role of the Multifunctional Calcium/Calmodulin-Dependent Protein Kinase II in Insulin Secretion

Description: Calcium/calmodulin-dependent protein kinase II (CaM kinase II) is demonstrated to exist in the ß-cell and immunopecipitation. Glucose and potassium significantly stimulate the rapid autophosphorylation of CaM kinase II and proportionally induce autonomous activity of the kinase in a dose-dependent manner that parallels insulin secretion. The activation of CaM kinase II, alloxan, KN-62 and KN-93, suggest that the enzyme is an integral component of insulin secretion and/or related processes in th… more

Synthesis, Purification and Pharacterization of Small Mono(ADP-Ribosyl)ated Molecules in the ADP-Ribose Elongation Reaction Catalyzed by Poly(ADP-ribose)Polymerase

Description: The ADP-ribose elongation catalyzed by poly(ADP-ribose) polymerase (PARP) [EC 2.2.2.30] has been partially characterized utilizing mono (ADP-ribosyl)ated polyamines. Arginine methyl ester (AME)-(ADP-ribose) and agmatine (AGMT)-(ADP-ribose) were synthesized enzymatically with a eukarytic mono(ADP-ribosyl) transferase and cholera toxin, respectively.

An Analysis of Adding Land Cover as a Variable to the DRASTIC Ground Water Model

Description: This study involved a geographic information systems (GIS) approach to modeling ground water pollution potential in the Southern Edwards Aquifer Region in Texas. The DRASTIC ground water model was analyzed using two methods. First, the effects of adding land cover data to the drastic model were evaluated. In the second approach, the effects of the removal of DRASTIC variables were evaluated. Six, five, and four variable models were generated and analyzed.

Microstructural Development of Simox and Simox Related Materials

Description: A novel structure related to Seperation by Implanted Oxygen (SIMOX) of NiSi2/SiO2/Si is studied for two primary reasons: the importance of metal silicide and insulating oxide in IC devices and the difficulty of direct growth of crystalline silicide on amorphous substrates.

Compliance-Gaining Among Anglo and Mexican-American Children

Description: This study investigates compliance-gaining rhetoric among Anglo and Mexican-American fourth graders in three schools in north Texas. The children were asked to respond to a scenario and to give a rationale for their persuasive strategies. An analysis of interviews with 52 children indicates that although the children used some similar strategies when attempting to gain compliance from an adult, there are also some significant differences between the two cultural groups.

Peculiar Honor: a History of the 28th Texas Cavalry (Dismounted), Walker's Texas Division, 1861-1865

Description: This study traces the history of the 28th Texas Cavalry by using a traditional narrative style augmented by a quantitative approach. Compiled service records, United States census records, state tax rolls, muster rolls, and casualty lists were used to construct a database containing a record for each soldier of the 28th. Statistical analysis revealed the overwhelming southern origins of the regiment, the greater proportion of older and married men compared to other regiments, and a close resemb… more

Genetic Organization and mRNA Expression of Enolase Genes of Candida Albicans

Description: The glycolytic enzyme enolase is an abundant, immunodominant antigen of the fungal pathogen Candida albicans. A C. albicans enolase cDNA was used to study the genetic organization and expression of enolase genes. Experimental results were consistent with a model predicting four enolase genes per diploid genome. Enolase steady state mRNA levels increased during logarithmic growth, but were unaffected by pH, growth form or carbon source.

Slime-Producing Coagulase-Negative Staphylococci Isolated from Human Eye Infections

Description: Some strains of coagulase-negative staphylococci produce an extracellular material, slime, which mediates adherence to foreign surfaces, such as indwelling biomedical devices. It is not known if slime is involved in adherence to human tissue. Coagulase-negative staphylococci are the most common members of normal ocular flora and cause many ocular infections, although the role of slime in these infections has not been studied.

Cellular Mechanisms of Ocular Hypotensive Effects of a₂-Adrenergic Agonists

Description: Th ocular bilateral hypotensive effect after unilateral topical administration of medetomidine and 4 analogs was demonstrated in a dose-response study (0.5%-2%) in NZW rabbits (bilateral IOP-lowering efficacy: medetomidine>detomidine and MPV-1440>MPV-1441 and MPV-305BIII).

Ultrastructure of Azotobacter Vinelandii

Description: The purpose of this research was to reveal the morphological and cytological characteristics of Azotobacter vinelandii cells cultured in dialyzed soil medium. Culture samples taken at two, four, eight, sixteen and thirty-two days were prepared and examined with the electron microscope. Comparisons of the morphology of Azotobacter vinelandii grown in dialyzed soil medium with those grown in Burk's nitrogen-free, chemically-defined medium were done.
