The medial amygdaloid nucleus in the adult male Syrian hamster (Mesocricetus auratus) is an important area along the chemosensory pathway where sensory and hormonal signals are processed for control of reproductive behavior. The studies described herein are a neuroanatomical des…

The purpose of these studies was to determine if the ICI itself was a characteristic of the animal model. Sprague Dawley rats, Brown Norway rats, wild Norway rats, Swiss Webster mice, obese mice, diabetic mice, cholecystectomized mice, Golden Syrian hamsters, Swiss Webster mice,…
The Na,K-pump plays an important role in cellular homeostasis by actively transporting sodium (Na+) out of cells and potassium (K+) into cells against their electrochemical gradients. The rate of Na,K-pumping depends, in part, on the intracellular Na+ concentration ((Na+\rbracki…
This dissertation is the description of the Bodo cranium (specimen number 266-1). The Bodo cranium is a fossil cranium that was discovered in Bodo D,Ar, Middle Awash Valley, Ethiopia in 1976. It is estimated to be of early Middle Pleistocene age perhaps around 700,000 years befo…
Statement of the problem. It is difficult to believe that in the twentieth century there are many countries that have hundreds of art and crafts museums and others that have almost none. Saudi Arabia has almost no art and crafts museums, with the exception of a few recent effort…
Developmental patterns of tissue ornithine decarboxylase (OCD) activity and nucleic acid concentrations were evaluated in breast and leg muscle in a randombred control population (RBC2), a line selected for increased 16-week body weight (F), and a commercial sire line selected f…
Lipogenic responsiveness to insulin was investigated at different times of day in freshly isolated hepatocytes and in primary cultured hepatocytes of Syrian hamsters, Mesocricetus auratus held on 14 hour daily photoperiods (lights on: 08.00) by following (('14)C)acetate incorpor…
Genetic selection for economic traits in modern strains of poultry has resulted in increased demands on skeletal integrity. Laying hens are highly susceptible to bone loss, osteoporosis and fractures of bone. Bone breakage also occurs in rapidly growing broiler chickens. Stronti…
Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the g…
Purpose. The purpose of this study was to determine the effect of the DonJoy Drytex Wraparound PlaymakerTM functional knee brace on the balance and proprioception, velocity, and agility of uninjured female athletes. Methods. Subjects were required to perform a 40-yard dash, a T-…
Arterial pulse pressure is critically important to a number of diseases such as isolated systolic hypertension, coronary artery disease and heart failure. Determining the cause of increased pulse pressure has been hampered for two reasons. First, pulse pressure results from cont…
Humans with diabetes mellitus are two to five times more likely to develop cardiovascular disease and do so at a much younger age than non-diabetics. This study utilized the Syrian F1B hamster, a model of human atherosclerosis, to: (1) determine whether one intraperitoneal injec…
Emphysema is a debilitating disease characterized by irreversible damage in the alveolar walls. A major consequence of this disease is diminished exercise capacity. Thirty-five adult male Golden Syrian hamsters were utilized to analyze cytochrome oxidase levels in the vastus lat…
We previously determined that fish oil induced hyperlipidemia in F 1B hamsters. In this study, we investigated the influence of fish oil enriched diets on lipid and lipoprotein metabolism in F1B and GS hamsters to determine if the response was preserved within animal strain. Ham…
Melanistic (uniformly black) species of cordylid lizards in the Western Cape of South Africa are generally distributed on cooler mountain tops and in peninsular areas, whereas lighter-colored congeners are found in warmer inland areas. The aim of this thesis was to study the the…
Glucocorticoids (GC) have been implicated in the development of central obesity and insulin resistance, two key characteristics of metabolic syndrome (MS). Recently, increased exposure to GC within insulin-sensitive tissues such as skeletal muscle, adipose, and liver have been a…
This research examines the metabolic and hormonal control of appetitive ingestive behavior in Syrian hamsters. Circulating metabolic fuels, leptin, insulin and levels of body fat change with metabolic challenges, and all have been implicated in the control of ingestive behavior.…
Obesity is characterized by multiple changes including expanded white adipose tissue (WAT) [1, 2]. During the last decade, WAT has been recognized as an active endocrine organ and a source of many pro-inflammatory cytokines, chemokines, and other proteins collectively called adi…
The present study was designed to investigate the dynamics for the release of vasoactive intestinal peptide (VIP) from the avian hypothalamus and to further characterize the alterations in VIP/peptide histidine isoleucine (PHI) gene expression that occur in several hypothalamic …
