The Pulmonary Effects Of Intravenous Adenosine In Asthmatic Subjects, Nausherwan K. Burki, Mahmud Alam, Lu-Yuan Lee

Physiology Faculty Publications

BACKGROUND: We have shown that intravenous adenosine in normal subjects does not cause bronchospasm, but causes dyspnea, most likely by an effect on vagal C fibers in the lungs [Burki et al. J Appl Physiol 2005; 98:180-5]. Since airways inflammation and bronchial hyperreactivity are features of asthma, it is possible that intravenous adenosine may be associated with an increased intensity of dyspnea, and may cause bronchospasm, as noted anecdotally in previous reports.

METHODS: We compared the effects of placebo and 10 mg intravenous adenosine, in 6 normal and 6 asthmatic subjects.

RESULTS: Placebo injection had no significant (p > 0.05) effect …

Managing Pasture Growth And Quality With Grazing, S. Ray Smith

Kentucky Grazing Conference

One of the keys to profitable livestock production is to minimize the costs of producing a marketable animal or animal product. Feed costs are commonly 70-80 percent of the cost of growing or maintaining an animal. Pastures provide feed at a cost of .01-.02 cents/lb of TDN while hay costs .04-.06 cents/lb TDN. Improved pasture management offers the single greatest opportunity to lower production costs, assuming that animal genetics, health, marketing procedures, and other areas of management have been addressed. A primary goal of livestock producers should be to utilize grazed forage for as many months of the year as …

The Lipogenic Enzymes Dgat1, Fas, And Lpl In Adipose Tissue: Effects Of Obesity, Insulin Resistance, And Tzd Treatment, Gouri Ranganathan, Resat Unal, Irina D. Pokrovskaya, Aiwei Yao-Borengasser, Bounleut Phanavanh, Beata Lecka-Czernik, Neda Rasouli, Philip A. Kern

Clinical and Translational Science Faculty Publications

Acyl-coenzyme A:diacylglycerol transferase (DGAT), fatty acid synthetase (FAS), and LPL are three enzymes important in adipose tissue triglyceride accumulation. To study the relationship of DGAT1, FAS, and LPL with insulin, we examined adipose mRNA expression of these genes in subjects with a wide range of insulin sensitivity (S_I). DGAT1 and FAS (but not LPL) expression were strongly correlated with S_I. In addition, the expression of DGAT1 and FAS (but not LPL) were higher in normal glucose-tolerant subjects compared with subjects with impaired glucose tolerance (IGT) (P < 0.005). To study the effects of insulin sensitizers, subjects with IGT were treated with pioglitazone or metformin for 10 weeks, and lipogenic enzymes were measured in adipose tissue. After pioglitazone treatment, DGAT1 expression was increased by 33 ± 10% (P < 0.05) and FAS expression increased by 63 ± 8% (P < 0.05); however, LPL expression was not altered. DGAT1, FAS, and LPL mRNA expression were not significantly changed after metformin treatment. The treatment of mice with rosiglitazone also resulted in an increase in adipose expression of DGAT1 by 2- to 3-fold, as did the treatment of 3T3 F442A adipocytes in vitro with thiazolidinediones. These data support a more global concept suggesting that adipose lipid storage functions to prevent peripheral lipotoxicity.

The Role Of Mapks In B Cell Receptor-Induced Down-Regulation Of Egr-1 In Immature B Lymphoma Cells, Jiyuan Ke, Murali Gururajan, Anupam Kumar, Alan Simmons, Lilia Turcios, Ralph Lakshman Chelvarajan, David M. Cohen, David L. Wiest, John G. Monroe, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Cross-linking of the B cell receptor (BCR) on the immature B lymphoma cell line BKS-2 induces growth inhibition and apoptosis accompanied by rapid down-regulation of the immediate-early gene egr-1. In these lymphoma cells, egr-1 is expressed constitutively and has a prosurvival role, as Egr-1-specific antisense oligonucleotides or expression of a dominant-negative inhibitor of Egr-1 also prevented the growth of BKS-2 cells. Moreover, enhancement of Egr-1 protein with phorbol 12-myristate 13-acetate or an egr-1 expression vector rescued BKS-2 cells from BCR signal-induced growth inhibition. Nuclear run-on and mRNA stability assays indicated that BCR-derived signals act at the transcriptional level to …

Navigating Adolescence With A Chronic Health Condition: A Perspective On The Psychological Effects Of Hair-An Syndrome On Adolescent Girls, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

HAIR-AN syndrome is a subphenotype of polycystic ovary syndrome and is characterized by acne, obesity, hirsutism, and acanthosis nigricans. It usually manifests in early adolescence, a time of significant developmental change in females across physical, cognitive, social, and emotional domains. We contend that adolescent development for females is difficult, even in the best of circumstances, and having a chronic health condition, like HAIR-AN syndrome, will likely impact the afflicted individual's development and psychological well-being. While many researchers have discussed the long-term health effects of HAIR-AN and similar disorders, little has been written about the potential psychological sequelae of HAIR-AN on …

A Missense Mutation In Pmel17 Is Associated With The Silver Coat Color In The Horse, Emma Brunberg, Leif Andersson, Gus Cothran, Kaj Sandberg, Sofia Mikko, Gabriella Lindgren

Veterinary Science Faculty Publications

BACKGROUND: The Silver coat color, also called Silver dapple, in the horse is characterized by dilution of the black pigment in the hair. This phenotype shows an autosomal dominant inheritance. The effect of the mutation is most visible in the long hairs of the mane and tail, which are diluted to a mixture of white and gray hairs. Herein we describe the identification of the responsible gene and a missense mutation associated with the Silver phenotype.

RESULTS: Segregation data on the Silver locus (Z) were obtained within one half-sib family that consisted of a heterozygous Silver colored stallion with 34 …

Aluminum Bioavailability From The Approved Food Additive Leavening Agent Acidic Sodium Aluminum Phosphate, Incorporated Into A Baked Good, Is Lower Than From Water, Robert A. Yokel, Rebecca L. Florence

Pharmaceutical Sciences Faculty Publications

There are estimates of oral aluminum (Al) bioavailability from drinking water, but little information on Al bioavailability from foods. Foods contribute ∼95% and drinking water 1–2% of the typical human's daily Al intake. The objectives were to estimate oral Al bioavailability from a representative food containing the food additive acidic sodium aluminum phosphate (acidic SALP), a leavening agent in baked goods. Rats were acclimated to a special diet that resulted in no stomach contents 14 h after its withdrawal. They were trained to rapidly consume a biscuit containing 1.5% acidic SALP. Oral Al bioavailability was then determined from a biscuit …

Lipin Expression Is Attenuated In Adipose Tissue Of Insulin-Resistant Human Subjects And Increases With Peroxisome Proliferator-Activated Receptor Γ Activation, Aiwei Yao-Borengasser, Neda Rasouli, Vijayalakshmi Varma, Lesliie M. Miles, Bounleut Phanavanh, Tasha Starks, Jack Phan, Horace J. Spencer Iii, Robert E. Mcgehee Jr., Karen Reue, Philip A. Kern

Clinical and Translational Science Faculty Publications

Lipin-α and -β are the alternatively spliced gene products of the Lpin1 gene, whose product lipin is required for adipocyte differentiation. Lipin deficiency causes lipodystrophy, fatty liver, and insulin resistance in mice, whereas adipose tissue lipin overexpression results in increased adiposity but improved insulin sensitivity. To assess lipin expression and its relation to insulin resistance in humans, we examined lipin-α and -β mRNA levels in subjects with normal or impaired glucose tolerance. We found higher expression levels of both lipin isoforms in lean, insulin-sensitive subjects. When compared with normal glucose-tolerant subjects, individuals with impaired glucose tolerance were more insulin resistant, …

From Healing The Whole Person: An Argument For Therapeutic Touch As A Complement To Traditional Medical Practice, Marlene B. Huff, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

The growing popularity and use of therapeutic touch (TT) is an issue that has generated controversy and concern within the medical community. While anecdotal and traditional scientific evidence suggest that TT would be an advantageous addition for clinics and hospitals to include in their armamentarium of complementary interventions within the realm of traditional medicine, TT has not become widely available in the U.S. One reason for the lack of availability may be the dearth of conclusive scientific support for TT's efficacy and, therefore, its inclusion in clinic and hospital treatment planning would give it the appearance of legitimate practice, which …

Correlation Between Number Of Retrieved Oocytes And Pregnancy Rate After In Vitro Fertilization/Intracytoplasmic Sperm Infection, Tanya Timeva, Tanya Milachich, Irena Antonova, Tanya Arabaji, Atanas Shterev, Hatim A. Omar

Pediatrics Faculty Publications

The implementation of safe and maximally effective ovarian stimulation is a major aim for in vitro fertilization (IVF) teams. The goal of controlled ovarian hyperstimulation (COH) is to supply enough oocytes with normal maturation to insure the consequent biological procedures. A variety of different stimulation protocols have been suggested and an individual selection of the correct stimulation protocol is mandatory. The aim of the present study is to evaluate the correlation between number of retrieved oocytes and clinical pregnancy rate (CPR) after IVF or intracytoplasmic sperm injection (ICSI) procedures. We reviewed 1017 cycles in a total of 975 patients. The …

Dissociation Of Automatic And Strategic Lexical-Semantics: Functional Magnetic Resonance Imaging Evidence For Differing Roles Of Multiple Frontotemporal Regions, Brian T. Gold, David A. Balota, Sara J. Jones, David K. Powell, Charles D. Smith, Anders H. Andersen

Neuroscience Faculty Publications

Behavioral research has demonstrated three major components of the lexical-semantic processing system: automatic activation of semantic representations, strategic retrieval of semantic representations, and inhibition of competitors. However, these component processes are inherently conflated in explicit lexical-semantic decision tasks typically used in functional magnetic resonance imaging (fMRI) research. Here, we combine the logic of behavioral priming studies and the neurophysiological phenomenon of fMRI priming to dissociate the neural bases of automatic and strategic lexical-semantic processes across a series of three studies. A single lexical decision task was used in all studies, with stimulus onset asynchrony or linguistic relationship between prime and …

Depression, Sensation Seeking, And Maternal Smoking As Predictors Of Adolescent Cigarette Smoking, Judy Van De Venne, Kay Bradford, Catherine A. Martin, Megan Cox, Hatim A. Omar

Family Sciences Faculty Publications

The purpose of this study was to examine maternal and adolescent depression, maternal and teen sensation seeking, and maternal smoking, and their associations with adolescent smoking. Data were collected from a sample of 47 male and 66 female adolescents (ages 11-18 years) and their mothers from three different health clinics. The findings indicated that maternal sensation seeking was linked indirectly with adolescent smoking through teen sensation seeking, both of which were significantly associated with teen smoking (β = 0.29, p < 0.001 and β = 0.32, p < 0.001, respectively). Teen depression was associated positively with teen smoking (β = 0.24, p < 0.01) when controlling for sensation seeking behaviors. Maternal smoking was also directly linked to adolescent smoking (β = 0.20, p < 0.05). These findings underscore a potentially important role of sensation seeking in the origins of adolescent smoking, and clarify pathways of influence with regard to maternal attitudes and behaviors in subsequent teenage nicotine use.
