Prolactin And Fmri Response To Skf38393 In The Baboon, Brad D. Miller, Lauren A. Marks, Jonathan M. Koller, Blake J. Newman, G Larry Bretthorst, Kevin J. Black Oct 2013

Prolactin And Fmri Response To Skf38393 In The Baboon, Brad D. Miller, Lauren A. Marks, Jonathan M. Koller, Blake J. Newman, G Larry Bretthorst, Kevin J. Black

Kevin J. Black, MD

Background: This study’s goal was to provide dose-response data for a dopamine agonist in the baboon using standard methods (replicate measurements at each dose, across a range of doses), as a standard against which to subsequently validate a novel pharmacological MRI (phMRI) method. Dependent variables were functional MRI (fMRI) data from brain regions selected a priori, and systemic prolactin release. Necessary first steps included estimating the magnitude and time course of prolactin response to anesthesia alone and to various doses of agonist. These first steps (“time course studies”) were performed with three agonists, and the results were used to select …

Preseason And Post Season Body Composition Does Not Change Relative To Playing Time In Division I Female Basketball Players, Emma Ladwig, Andrew Shim, Jae Yom, Patrick Cross, Justin Beebe Jul 2013

Preseason And Post Season Body Composition Does Not Change Relative To Playing Time In Division I Female Basketball Players, Emma Ladwig, Andrew Shim, Jae Yom, Patrick Cross, Justin Beebe

International Journal of Exercise Science 6(3) : 208-216, 2013. The purpose of the study was to determine if preseason and postseason body fat percentages (BF%) change relative to playing time in Division I women’s basketball players. Subjects for the study included 11 National Collegiate Athletic Association (NCAA) Division I female collegiate basketball athletes over the age of 18 from a Midwest public university. Demographic data of each subject (age 20.09 +1.81 yrs., weight 71.13 +10.85 kg., height 176.48 + 8.33 cm.) was taken before the initial body fat assessment. The subjects underwent preseason and postseason BOD POD® testing to get …

Alcohol-Induced Il-1beta In The Brain Is Mediated By Nlrp3/Asc Inflammasome Activation That Amplifies Neuroinflammation, Dora Lippai, Shashi Bala, Jan Petrasek, Timea Csak, Ivan Levin, Evelyn Kurt-Jones, Gyongyi Szabo Jul 2013

Alcohol-Induced Il-1beta In The Brain Is Mediated By Nlrp3/Asc Inflammasome Activation That Amplifies Neuroinflammation, Dora Lippai, Shashi Bala, Jan Petrasek, Timea Csak, Ivan Levin, Evelyn Kurt-Jones, Gyongyi Szabo

Alcohol-induced neuroinflammation is mediated by proinflammatory cytokines, including IL-1beta. IL-1beta production requires caspase-1 activation by inflammasomes-multiprotein complexes that are assembled in response to danger signals. We hypothesized that alcohol-induced inflammasome activation contributes to increased IL-1beta in the brain. WT and TLR4-, NLRP3-, and ASC-deficient (KO) mice received an ethanol-containing or isocaloric control diet for 5 weeks, and some received the rIL-1ra, anakinra, or saline treatment. Inflammasome activation, proinflammatory cytokines, endotoxin, and HMGB1 were measured in the cerebellum. Expression of inflammasome components (NLRP1, NLRP3, ASC) and proinflammatory cytokines (TNF-alpha, MCP-1) was increased in brains of alcohol-fed compared with control mice. Increased …

A Diabetic Adolescent Case Study: Use Of A Website In Combination With An Exercise Program To Increase Physical Activity, Danielle Buckley, Nicole Demilia, Stephanie Tanzi, Furong Xu, Linda Lamont Jun 2013

A Diabetic Adolescent Case Study: Use Of A Website In Combination With An Exercise Program To Increase Physical Activity, Danielle Buckley, Nicole Demilia, Stephanie Tanzi, Furong Xu, Linda Lamont

Linda S. Lamont Ph.D.

International Journal of Exercise Science 5(3) : 296-300, 2012. The purpose of this study was to report on the efficacy of a web-based technology support to encourage physical activity in children. This program was designed to promote physical activity and proper nutrition in the diabetic adolescent with a weekly meeting that consisted of a 30-minute educational session followed by 60-minutes of exercise. A specifically designed website was used as a support to this weekly supervised exercise program. Outcomes assessment included body mass index (BMI), muscle strength (grip strength, back and leg strength), flexibility, exercise self-efficacy, and physical activity participation (pedometer, …

Refeeding After Acute Food Restriction: Differential Reduction In Preference For Ethanol And Ethanol-Paired Flavors In Selectively Bred Rats., Clinton Chapman, Nancy Dess, Laura Cousins, Phuong Nguyen Jan 2013

Refeeding After Acute Food Restriction: Differential Reduction In Preference For Ethanol And Ethanol-Paired Flavors In Selectively Bred Rats., Clinton Chapman, Nancy Dess, Laura Cousins, Phuong Nguyen

Rats' voluntary ethanol intake varies with dispositional factors and energy status. The joint influences of these were of interest here. We previously reported that rats selectively bred for high voluntary saccharin intake (HiS) consume more ethanol and express more robust conditioning of preference for flavors paired with voluntarily consumed ethanol than do low-saccharin consuming counterparts (LoS). Three new experiments examined the effect of refeeding after an episode of food restriction on ethanol intake and on preference for ethanol-paired flavors in HiS and LoS rats. A 48-h episode of food restriction with wheel running reduced intake of and preference for 4% …
