A comparison of the effects of estrogen and progesterone on cholecystokinin and KCl-induced tension in female guinea pig gallbladder strips
Meeting Abstract 98.5 Sunday, Jan. 6 A comparison of the effects of estrogen and progesterone on cholecystokinin and KCl-induced tension in female guinea pig gallbladder strips KLINE, L.W.*; KARPINSKI, E.; University of Alberta, Edmonton lkline@ualberta.ca Estrogen has an inhibitory effect on the contractility of gastrointestinal smooth muscle, including the gallbladder. This study investigated the effect of 17 […]
The effects of food macronutrient content on an insect herbivore a fitness landscape approach
Meeting Abstract 98.5 Monday, Jan. 6 14:30 The effects of food macronutrient content on an insect herbivore: a fitness landscape approach. LE GALL, M.*; BEHMER, S.T.; Texas A&M University; Texas A&M University le-marron@tamu.edu The plants that insect herbivores eat can be highly variable with respect to their protein and digestible carbohydrate content. Here we explore the effects […]

Mechanistic correlates of paracellular nutrient absorption in protein specialists
Meeting Abstract 98.3 Monday, Jan. 6 14:00 Mechanistic correlates of paracellular nutrient absorption in protein specialists PRICE, E.R.*; CAVIEDES-VIDAL, E.; KARASOV, W.H.; University of Wisconsin-Madison; Universidad Nacional de San Luis; University of Wisconsin-Madison eprice2@wisc.edu Water-soluble nutrients (e.g., glucose and amino acids) can be absorbed across enterocytes via protein-mediated transport, or paracellularly through the tight junctions between enterocytes. […]
Lipid digestion and absorption are impaired during an alphavirus infection in nestling birds
Meeting Abstract 98.1 Monday, Jan. 6 13:30 Lipid digestion and absorption are impaired during an alphavirus infection in nestling birds GOTO, D*; RAINWATER, E; FASSBINDER-ORTH, C; Creighton University; Creighton University; Creighton University carolfassbinder-orth@creighton.edu Nestling birds serve as reservoirs for several arthropod-borne diseases, especially arboviruses. However, few studies have investigated the effects of an arbovirus infection on nestlings […]
Isotope labeled metabolic tracers are not created equal comparing the oxidative kinetics of free- versus biochemically-integrated dietary nutrients
Meeting Abstract 98.8 Monday, Jan. 6 15:15 Isotope labeled metabolic tracers are not created equal: comparing the oxidative kinetics of free- versus biochemically-integrated dietary nutrients MCCUE, M D*; CARDENTEY, A; St. Mary’s University mmccue1@stmarytx.edu Clinicians and researchers are increasingly using 13CO2-breath-testing to diagnose metabolic disorders, especially those related to protein and lipid metabolism. Breath testing involves giving […]
