Innate fear is critical for the survival of animals and is under tight homeostatic control. Deregulation of innate fear processing is thought to underlie pathological phenotypes including, phobias and panic disorders. Although central processing of conditioned fear has been extensively studied, the circuitry and regulatory mechanisms subserving innate fear remain relatively poorly defined. In t...
CART (cocaine and amphetamine regulated transcript) peptide functions as both a neurotransmitter and a hormone and is found both in the central nervous system (CNS) and in the periphery. CART peptide in the nucleus accumbens (NAc) has been implicated in the regulation of cocaine-dopamine-mediated locomotion and self-administration, and amphetamine-mediated locomotion and behavior. However, ther...
We present advances in Bayesian modeling and computation for CART (classification and regression tree) models. The modeling innovations include a formal prior distributional structure for tree generation – the pinball prior – that allows for the combination of an explicit specification of a distribution for both the tree size and the tree shape. The core computational innovations involve a nove...
BACKGROUND Cocaine- and amphetamine-regulated transcript (CART) has been demonstrated to play a role in regulating the rewarding and reinforcing effects of various drugs of abuse. A recent study demonstrated that i.c.v. administration of CART negatively modulates reinstatement of alcohol seeking, however, the site(s) of action remains unclear. We investigated the paraventricular thalamus (PVT) ...
BACKGROUND The HIV-Brazil Cohort Study was established to analyze the effectiveness of combination antiretroviral therapy (cART) and the impact of this treatment on morbidity, quality of life (QOL) and mortality. The study design, patients' profiles and characteristics of cART initiation between 2003 and 2010 were described. METHODOLOGY/PRINCIPAL FINDINGS Since 2003, the HIV-Brazil Cohort has...
BACKGROUND Despite the known substantial benefits of combination antiretroviral therapy (cART), cumulative adverse effects could still limit the overall long-term treatment benefit. Therefore we investigated changes in the rate of death with increasing exposure to cART. METHODS A total of 12 069 patients were followed from baseline, which was defined as the time of starting cART or enrolment ...
Immunization studies with modified gp120 monomers using a hyperglycosylation strategy, in which undesired epitopes are masked by the selective incorporation of N-linked glycans, were described in a previous paper (Selvarajah S, et al., J Virol 2000;79:12148-12163). In this report, we applied the hyperglycosylation strategy to soluble uncleaved gp140 trimers to improve the antigenic and immunoge...
INTRODUCTION In the central nervous system, cocaine- and amphetamine-regulated transcript (CART) 55-102 peptide is localized in areas, such as the ventral tegmental area, amygdala, hypothalamus, and hippocampus, where emotional activity is regulated. Studies on the effects of the intracerebroventricular (ICV) administration of CART peptide on behavior remain limited. The findings from these stu...
The purpose of this study was to characterize the inhibitory modulation of cocaine- and amphetamine-regulated transcript (CART) peptides, particularly with respect to the function of the D3 dopamine receptor (D3R), which is activated by its interaction with phosphorylated CaMKIIα (pCaMKIIα) in the nucleus accumbens (NAc). After repeated oral administration of caffeine (30 mg/kg) for five days, ...
This study aimed to evaluate plasma concentration of selected cancer-associated inflammatory and immune-modulated cytokines in HIV+ patients with advanced Kaposi sarcoma (KS), and to explore candidate biomarkers capable of predicting clinical outcome in response to chemotherapy (CT) plus combination antiretroviral therapy (cART).Thirty-seven plasma cytokines/chemokines were assessed by Luminex ...
