Ventricular Expansion in Wild-Type Wistar Rats After Alcohol Exposure By Vapor Chamber
Here, we tested the hypothesis that wild-type Wistar rats, exposed to vaporized alcohol ensuring higher BALs than typically achieved with voluntary consumption in rodents, would model MRI findings in the…

Hypocretin/Orexin and Nociceptin/Orphanin Fq Coordinately Regulate Analgesia in a Mouse Model of Stress-Induced Analgesia
Stress-induced analgesia (SIA) is a key component of the defensive behavioral “fight-or-flight” response. Although the neural substrates of SIA are incompletely understood, previous studies have implicated the hypocretin/orexin (Hcrt) and…

Shock Veins in L6 Chondrites and Constraints on the Impact History of the L6 Parent Body
In this study we use hydrodynamic calculations to explore possible impact conditions and sample locations on the L6 parent body for the highly shocked L6 chondrite RC106.

Hypoxia Signals Autophagy in Tumor Cells Via AMPK Activity, Independent of HIF-1, BNIP3, and BNIP3L
Here we report that oxygen deprivation can activate the autophagic pathway in human cancer cell lines. We observed that hypoxia induced distinct cellular changes characteristic of autophagy such as an…

Systematic Biological Prioritization After a Genome-Wide Association Study: an Application to Nicotine Dependence
We introduce a method for systematically prioritizing single nucleotide polymorphisms (SNPs) for further study after a GWAS. The method combines evidence across multiple domains including statistical evidence of genotype–phenotype correlation,…

Diffusion Tensor Tractography in Mesencephalic Bundles: Relation to Mental Flexibility in Detoxified Alcohol-Dependent Subjects
Components of the corticocerebellar circuit and the midbrain individually play a central role in addictive processes and have been associated with altered volumes and impairment of cognitive flexibility in alcohol-dependent…

Nociceptin Attenuates Methamphetamine Abstinence-Induced Withdrawal-Like Behavior in Planarians
In the present study, we tested the hypothesis that abrupt discontinuation of methamphetamine would also cause withdrawal-like behavior in planarians and that the withdrawal-like behavior would be prevented by nociceptin,…

Gamma-Aminobutyric Acid Receptor Genes and Nicotine Dependence: Evidence for Association from a Case-Control Study
We found evidence for association between four SNPs in GABRA4, two SNPs in GABRA2 and one SNP in GABRE with nicotine dependence.

Image-Guided Surgical Navigation in Implant-Based Auricular Reconstruction
In cases where surgical reconstruction is not an option, placement of osseo-integrated implants for an auricular prosthesis can be done in 1 or 2 stages in a relatively short period…

Nicotinic Acetylcholine Receptor Beta 2 Subunit Gene Implicated in a Systems-Based Candidate Gene Study of Smoking Cessation
We performed a systems-based candidate gene study of 1295 single nucleotide polymorphisms (SNPs) in 58 genes within the neuronal nicotinic receptor and dopamine systems to investigate their role in smoking…

Perceived Sleep Quality and Sleepiness in South African University Students
Nine hundred and eighty-six undergraduate students completed a questionnaire about their sleep and lifestyle habits over the previous month, and their fatigue-related driving history.
