PURPOSE Metastatic malignant melanoma is a devastating disease with a poor prognosis. Recent therapeutic trials have focused on immunotherapy to induce development of endogenous antitumor immune responses. To date, such protocols have shown success in activation of tumor-specific CTL but no overall improvement in survival. To kill tumor, antigen-specific(More)
Mutations in hepatocyte nuclear factor 1alpha (HNF-1alpha) lead to maturity-onset diabetes of the young type 3 as a result of impaired insulin secretory response in pancreatic beta-cells. The expression of 50 genes essential for normal beta-cell function was studied to better define the molecular mechanism underlying the insulin secretion defect in(More)
OBJECTIVES To estimate the prevalence of complementary and alternative medicine (CAM) usage among emergency department (ED) patients. METHODS This study was a cross-sectional study in four Boston-area EDs. For two 24-hour periods, the authors interviewed consecutive patients age 18 and older about whether they had ever used or had recently (within the(More)
To ensure learning, game-based learning environments must incorporate assessment mechanisms, e.g. Intelligent Tutoring Systems (ITSs). ITSs are focused on recognising and influencing the learner’s emotional or motivational states. This research focuses on designing and implementing an affective student model for intelligent gaming, which reasons about the(More)
Game-based learning offers key advantages for learning through experience in conjunction with offering multi-sensorial and engaging communication. However, ensuring that learning has taken place is the ultimate challenge. Intelligent Tutoring Systems (ITSs) have been incorporated into game-based learning environments to guide learners’ exploration. Emotions(More)
During human immunodeficiency virus (HIV) infection, alcohol has been known to induce inflammation while cannabinoids have been shown to have an anti-inflammatory role. For instance cannabinoids have been shown to reduce susceptibility to HIV-1 infection and attenuate HIV replication in macrophages. Recently, we demonstrated that alcohol induces cannabinoid(More)
BACKGROUND Genetic factors account for about fifty percent of the risk for alcoholism and alcohol dependence (AD) has been reported to be influenced by cannabinoid receptors (CBRs) and the endocannabinoid system (ECS). Previous studies have focused on cannabinoids and alcohol-related effects in the CNS; however, the role CBRs play on alcohol effects in the(More)
Due to the legalization of marijuana and the increased demand for cannabis and alcohol consumption, research efforts highlighting the biomedical consequences of the use of alcohol and cannabinoids are not only relevant to the substance abuse scientific field, but are also of public health interest. Moreover, an overview of the recent literature about(More)
Epigenetic mechanisms have been shown to play a role in alcohol use disorders (AUDs) and may prove to be valuable therapeutic targets. However, the involvement of histone deacetylases (HDACs) on alcohol-induced oxidative stress of human primary monocyte-derived dendritic cells (MDDCs) has not been elucidated. In the current study, we took a novel approach(More)
