In observational studies, habitual coffee consumption has been linked to a lower risk of type 2 diabetes. We hy-pothesized that the mechanism may be related to delayed effects on postprandial glycemia. The aim of this study is to investigate the glycemic and insulinemic effects of consumption of caffeinated and decaffeinated coffee, sweetened and unsweetened, tea and sucrose, 1 h prior to a high carbohydrate meal. On separate occasions in random order, lean young healthy subjects (n = 8) consumed a potato-based meal 1 hour after consumption of 250 mL of black coffee (COF), black coffee sweetened with 10 g of …

Cannabis increases the risk of schizophrenia in genetically vulnerable individuals. In this study we aim to show that the schizophrenia susceptibility gene neuregulin 1 (Nrg1) modulates the development of tolerance to cannabinoids in mice. Nrg1 heterozygous (HET) and wild-type (WT) mice were treated daily for 15 d with the synthetic analogue of D9-tetrahydrocannabinol, CP55,940 (0.4 mg/kg). We measured the impact of this exposure on locomotor activity, anxiety, prepulse inhibition (PPI), body temperature and FosB/DFosB immunohistochemistry. Tolerance to CP55,940-induced hypothermia and locomotor suppression developed more rapidly in Nrg1 HET mice than WT mice. Conversely in the light-dark test, while tolerance to …

Short- And Long-Term Effects Of Antipsychotic Drug Treatment On Weight Gain And H1 Receptor Expression, Kelly Newell, Xu-Feng Huang, Chao Deng, Tom Burne, Mei Han
Xu-Feng Huang
The present study investigated body weight gain, food intake, open-field activity and brain histamine H1 receptor mRNA and protein expression in rats treated with three types of antipsychotics. Rats were divided into eight groups and treated with aripiprazole (2.25mg/kg/day), olanzapine (1.5mg/kg/day), haloperidol (0.3mg/kg/day) or vehicle (as control) for 1 or 12 weeks. Administration of olanzapine for 1 week led to a threefold increase in body weight gain and a 35% increase in fat deposits compared to controls (p<0.05). In the 12-week olanzapine treatment group, accumulative food intake was significantly higher in the first 7 weeks of treatment compared to …

Background and aims: Decreasing energy intake relative to energy expenditure is the indisputable tenet of weight loss. In addition to caloric restriction modification of the type of dietary fat may provide further benefits. The aim of the present study was to examine the effect of energy restriction alone and with dietary fat modification on weight loss and adiposity, as well as on risk factors for obesity related disease. Methods and results: One-hundred and fifty overweight men and women were randomized into a 3 month controlled trial with four low fat (30% energy) dietary arms: (1) isocaloric (LF); (2) isocaloric with …

This study examined the effects of different food sources of protein on energy intake, body weight maintenance, and on the responses of plasma leptin, insulin and adiponectin in chronic high-fat diet-induced obese mice. Obesity was induced in 47 mice with a high-fat diet for 20 weeks. They were divided into five diet groups to test the effects of a higher protein proportion (30% energy), achieved at the expense of carbohydrate. For the next eight weeks, four of the groups were fed diets of chow formulated with whey, soy, red meat or milk while the control group continued on their high-fat …

Aripiprazole Differentially Affects Mesolimbic And Nigrostriatal Dopaminergic Transmission: Implications For Long-Term Drug Efficacy And Low Extrapyramidal Side-Effects, Xu-Feng Huang, Chao Deng, Mei Han
Xu-Feng Huang
Aripiprazole has been used effectively to treat schizophrenia in the clinic ; however, its mechanisms ofaction are not clear. This study examined how short- and long-term aripiprazole treatment affects dopaminergic transmission in mesolimbic and nigrostriatal pathways. For comparison, the effects of haloperidol and olanzapine treatment were also examined. Aripiprazole significantly increased D2 receptor mRNA expression and decreased tyrosine hydroxylase (TH) mRNA expression in the ventral tegmental area (VTA) after 1- and 12-wk treatment, but had no effect in substantia nigra (SN) and nucleus accumbens (NAc). Aripiprazole also decreased dopamine transporter (DAT) binding density in NAc (for 1- and 12- wk …

This study examined regional changes of peptide YY (PYY) binding densities in the rat brain after chronic administration of olanzapine (1.2 mg/kg/day and haloperidol (2.0 mg/kg/day)for 36 days. PYY binding densities and distributions were detected by [125I] binding autoradiography after ratswere sacrificed either 2 h or 48 h after the last drug administration to examine both immediate and delayed effects following the drugwithdrawal. Following 2 h of drug administration, it showed that olanzapine administration significantly decreased PYY binding densities, predominantly in the posterodorsal part of medial amygdaloid nucleus (52 percent, pb0.05), dorsal part of medial geniculate nucleus (56 percent, pb0.05), …

Alterations in muscarinic M1 receptor protein and mRNA expression have been revealed in post-mortem brains of schizophrenia patients. Most patients had been treated with antipsychotics, so medication effects cannot be excluded as a possible explanation for these results. With in situ hybridization, this study investigated M1 receptor mRNA expression in rats treated with the typical antipsychotic haloperidol (0.3 mg/kg/day) and the atypical antipsychotics olanzapine (1.5 mg/kg/day) and aripiprazole (2.25 mg/kg/day) for 1 or 12 weeks. Compared with the control group, haloperidol significantly increased (13-21%, P < 0.05) M1 mRNA expression in the CA1, CA2, and CA3 regions of the hippocampus after both 1 and 12 weeks of treatment, and it also increased (17%, P < 0.01) M1 mRNA expression in the substantia nigra compacta after 1 week of treatment. Olanzapine significantly increased (14-22%, P < 0.05) M1 mRNA expression in the hippocampus (CA1, CA2, and CA3) and substantia nigra compacta after 12 weeks of treatment, but not after 1 week. Aripiprazole significantly increased (17%, P < 0.01) M1 mRNA expression in the hippocampus (CA1) after both 1 and 12 week treatments and increased (12%, P < 0.05) M1 mRNA expression in the nucleus accumbens after 1 week of treatment. Despite their different affinities for muscarinic M1 receptors, all three antipsychotic medications induced a similar trend of change in M1 mRNA expression in selected brain regions. These data suggest that the decreased M1 receptor protein and mRNA expression observed in schizophrenia patients is unlikely to be a consequence of drug treatments and implicates muscarinic M1 receptors in the pharmacotherapy of the disease.

Aim: The aim of this research was to test the efficacy of manipulating dietary soluble fibre while matching other macronutrients in a weight reduction intervention. The proposed mechanism was an increase in satiety to aid dietary compliance in the intervention groups. Methods: Foods were developed using a range of fibre doses. An acute meal test study measured biochemical markers, subjective measures of satiety and meal intake data. Results from this study informed development of cereal and snack products to be included in the weight loss study. Dietary compliance in the intervention trial was then measured using 3-day food records and …

USF Tampa Graduate Theses and Dissertations
Prevalence rates of youth prescribed psychotropic medications have risen dramatically over the past decade. Many of these medications are prescribed to treat symptoms of a disorder that occur in the school setting. Some medications have negative side effects that can inhibit academic and social performance. School psychologists have been identified as professionals who are equipped to assist in monitoring both the beneficial and negative effects of medications for youth attending school. This study investigated the practices, training, types of disorders for which medication monitoring occurs, facilitators, and barriers to school psychologists engaging in medication monitoring in the schools. Survey data …
