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.

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.

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…

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…

Synthesis of Two Potential Heterocyclic Amine Food Mutagens
The syntheses of two potential food mutagens formed during cooking, 2-amino-3,6,7-trimethyl-3H-imidazo[4,5-b]pyridine (1) and 2-amino-3,6,7-trimethyl-3H-imidazo[4,5-c]pyridine (2), are described.

Temperature Dependence of Oxygen Atom Recombination in Nitrogen After Ozone Photolysis
Oxygen atom decays in nitrogen were measured by laser induced fluorescence following complete photodissociation of ozone at 248 nm.

Using Semantic Features to Improve Task Identification in Email Messages
This paper addresses the lack of training data using domain-specific semantic features in document representation for reducing vocabulary mismatches and enhancing the discriminative power of trained classifiers.

Scene-Based Nonuniformity Correction Using Local Constant Statistics
Our method proposes a local-constant statistics that assumes that the temporal signal distribution is not constant at each pixel but is locally true.

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…

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…
