Hand Use Predicts The Structure Of Representations In Sensorimotor Cortex., Naveed Ejaz, Masashi Hamada, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Fine finger movements are controlled by the population activity of neurons in the hand area of primary motor cortex. Experiments using microstimulation and single-neuron electrophysiology suggest that this area represents coordinated multi-joint, rather than single-finger movements. However, the principle by which these representations are organized remains unclear. We analyzed activity patterns during individuated finger movements using functional magnetic resonance imaging (fMRI). Although the spatial layout of finger-specific activity patterns was variable across participants, the relative similarity between any pair of activity patterns was well preserved. This invariant organization was better explained by the correlation structure of everyday hand movements than …

BACKGROUND: Genome-wide association studies have identified multiple genetic variants associated with prostate cancer risk which explain a substantial proportion of familial relative risk. These variants can be used to stratify individuals by their risk of prostate cancer.

METHODS: We genotyped 25 prostate cancer susceptibility loci in 40,414 individuals and derived a polygenic risk score (PRS). We estimated empirical odds ratios (OR) for prostate cancer associated with different risk strata defined by PRS and derived age-specific absolute risks of developing prostate cancer by PRS stratum and family history.

RESULTS: The prostate cancer risk for men in the top 1% of the …

Obesity Early In Adulthood Increases Risk But Does Not Affect Outcomes Of Hepatocellular Carcinoma, Manal M. Hassan, Reham Abdel-Wahab, Ahmed Kaseb, Ahmed Shalaby, Alexandria Phan, Hashem El-Serag, Ernest Hawk, Jeff Morris, Kanwal Pratap Singh Raghav, Ju-Seog Lee, Jean-Nicolas Vauthey, Gehan Bortus, Harrys Torres, Christopher Amos, Robert Wolff, Donghui Li

Dartmouth Scholarship

Despite the significant association between obesity and several cancers, it has been difficult to establish an association between obesity and hepatocellular carcinoma (HCC). Patients with HCC often have ascites, making it a challenge to accurately determine body mass index (BMI), and many factors contribute to the development of HCC. We performed a case–control study to investigate whether obesity early in adulthood affects risk, age of onset, or outcomes of patients with HCC.

Supporting Adult Learners' Metacognitive Development With A Sociotechnical System, Kathryn Wozniak

College of Computing and Digital Media Dissertations

Metacognition is defined as thinking about and reflecting on one's cognitive processes. In learning contexts, strong metacognition leads to retention, academic success, and deep learning. While we know a lot about the metacognition of learners in grades K-12 and college, there are limited studies on adult learners' (24 and older) metacognitive awareness, how to support it, or the role technology can play, particularly since e-learning is quickly becoming the central mode of learning for adult learners. Thus, I have the following motivating research question: How can we support adult learners' metacognitive development in e-learning environments?

To better understand adult learners' …

Fusion Analysis Of Functional Mri Data For Classification Of Individuals Based On Patterns Of Activation., Mahdi Ramezani, Purang Abolmaesumi, Kris Marble, Heather Trang, Ingrid Johnsrude

Brain and Mind Institute Researchers' Publications

Classification of individuals based on patterns of brain activity observed in functional MRI contrasts may be helpful for diagnosis of neurological disorders. Prior work for classification based on these patterns have primarily focused on using a single contrast, which does not take advantage of complementary information that may be available in multiple contrasts. Where multiple contrasts are used, the objective has been only to identify the joint, distinct brain activity patterns that differ between groups of subjects; not to use the information to classify individuals. Here, we use joint Independent Component Analysis (jICA) within a Support Vector Machine (SVM) classification …

Genetic Heterogeneity Of Pseudoxanthoma Elasticum: The Chinese Signature Profile Of Abcc6 And Enpp1 Mutations., Liang Jin, Qiujie Jiang, Zhengsheng Wu, Changxia Shao, Yong Zhou, Luting Yang, Jouni Uitto, Gang Wang

Department of Dermatology and Cutaneous Biology Faculty Papers

Pseudoxanthoma elasticum (PXE), an autosomal recessive disorder characterized by ectopic mineralization, is caused by mutations in the ABCC6 gene. We examined clinically 29 Chinese PXE patients from unrelated families, so far the largest cohort of Asian PXE patients. In a subset of 22 patients, we sequenced ABCC6 and another candidate gene, ENPP1, and conducted pathogenicity analyses for each variant. We identified a total of 17 distinct mutations in ABCC6, 15 of them being, to our knowledge, previously unreported, including 5 frameshift and 10 missense variants. In addition, a missense mutation in combination with a recurrent nonsense mutation in ENPP1 was …

Adolescent And Adult African Americans Have Similar Metabolic Dyslipidemia., Samuel S. Gidding, Scott W. Keith, Bonita Falkner

Department of Pharmacology and Experimental Therapeutics Faculty Papers

BACKGROUND: African Americans (AAs) have lower triglyceride (TG) and higher high-density lipoprotein cholesterol (HDL-C) than other ethnic groups; yet, they also have higher risk for developing diabetes mellitus despite the strong relationship of dyslipidemia with insulin resistance. No studies directly compare adolescents and adults with regard to relationships among dyslipidemia, high-sensitivity C-reactive protein (hs-CRP), and insulin resistance. Here, we compare AA adolescents to adults with regard to the relationships of adiposity-related lipid risk markers (TG-to-HDL ratio and non-HDL-C) with body mass index (BMI), waist circumference (WC), homeostasis model of insulin resistance (HOMA), and hs-CRP.

METHODS: Two cohorts of healthy AA …

Targeted Single Molecule Sequencing Methodology For Ovarian Hyperstimulation Syndrome., Funda Orkunoglu-Suer, Arthur F. Harralson, David Frankfurter, Paul Gindoff, Travis J. O'Brien

Genomics and Precision Medicine Faculty Publications

BACKGROUND: One of the most significant issues surrounding next generation sequencing is the cost and the difficulty assembling short read lengths. Targeted capture enrichment of longer fragments using single molecule sequencing (SMS) is expected to improve both sequence assembly and base-call accuracy but, at present, there are very few examples of successful application of these technologic advances in translational research and clinical testing. We developed a targeted single molecule sequencing (T-SMS) panel for genes implicated in ovarian response to controlled ovarian hyperstimulation (COH) for infertility.

RESULTS: Target enrichment was carried out using droplet-base multiplex polymerase chain reaction (PCR) technology (RainDance®) …
