Meta-analysis of the population and phenotypic expression of CYP2C9/2C19 polymorphism on drug metabolism in different ethnicities
The term "pharmacogenetics" has been defined as the scientific study of inherited factors that affect the human drug response. Many pharmacogenetie studies have been published since 1995 and have focussed on the principal enzyme family involved in drug metabolism, the cytochrome P450 family, …

Psychopathy as a female phenotypic expression of borderline personality disorder? Implications for the latent structure of emotional dysregulation
… emotional dysregulation established per Goal 2 phenotypically manifests in terms of secondary psychopathy in women versus men (Goal #3). Similar to the findings of Goal #1, results indicated that the interaction of F1 and F2 psychopathy scores is associated with emotional dysregulation among …

Elaborating Borderline and Psychopathic Personality with the Computerized Adaptive Test of Personality Disorder in a Female Correctional Sample
… Disorder (BPD) may represent a female phenotypic expression of PPD, particularly among incarcerated offenders. The current study examined distinction and convergence between PPD and BPD. Utilizing a sample of 146 female correctional inmates as well as 109 female college students, the …

In vitro studies of the impact of ozone and sulfur dioxide on the pollen of Fraser fir (Abies fraseri (Pursh) Poir.)
… due to genotype of the pollen parent tree. The phenotypic expression of six isozymes (previously correlated with resistance to air pollutants) in pollen was studied using polyacrylamide gel electrophoresis. The pattern of isozyme distribution among pollen phenotypes confirmed results from pollen …

Parallels and Divergences in Multisystem Proteinopathy Genes: Stress Granules, Autophagy, and Myogenic Deficits
… Several different genes give rise to the unique phenotypic expression of MSP. Given the variety of genes that cause MSP and the specificity of the phenotype and tissue involvement, we asked; what are the unifying pathogenic features of MSP? To address this, we examined three areas of interest: …

An Evaluation of the Convergent Construct Validity of the Boldness Inventory of Psychopathy using a Five-Minute, 10% Carbon-Dioxide-Enriched Air Challenge
… in the detection of threat and represents a phenotypic expression of fearlessness. Two principal problems in studies on psychopathy and fearlessness are the use of varying operationalizations of fear and an overreliance on non-laboratory-based methods to assess it. The current study examined …

Gene Mapping of Morphological Traits in Chickens
… of how background genome can influence the phenotypic expression of single genes (gene genetic background interactions) and an understanding of cellular and molecular mechanisms involved in morphogenesis.

Correlations Between Electron Microscopic and Classical Analytic Observations of Three Strains of Temperature-Sensitive Male Sterility Mutants of <em>Drosophila melanogaster</em>.
Spermatogenesis is a specialized case of cytodifferentiation involving the assembly of cellular components into haploid gametes. It is directed, presumably, by the sequential activation and repression of genes.

Using Deep Learning to predict the mortality of Leukemia patients
… doctors. The genotypic (actual set of genes), phenotypic (expression of those genes in observable traits) and clinical information is used to stratify children into various risk categories. The information collected by doctors for risk-stratification include response to certain drugs, clinical …

A diversified exploration of beef cattle genetics: miRNA and beef bull fertility in beef and dairy female populations
… analysis of micro ribonucleic acid (miRNA) expression as it relates to quantitative traits, genetic analysis of sire conception rate (SCR) in dairy cow and beef heifer populations, and the genetic correlation between SCR in both populations. The objectives of the miRNA project were to …

Oxygen Transport, Shear Stress, And Metabolism In Perfused Hepatocyte-Seeded Scaffolds With Radial Pore Architecture: Experimental And Computational Analyses
… via reduced scaffold dimensions, would affect phenotypic expression and viability. It was discerned that increasing the cell packing density by 14% increased the rate of albumin and urea production by 79% and 40% respectively. In total the results show that the experimental measures conducted …

The interaction of diet and mitochondrial DNA on mitochondrial function and organismal fitness
… in phenotype. Secondly, this variation in phenotypic expression is regulated by mitochondrial functions. Lastly, diet can influence mitochondrial functions and influence the phenotype of the organism. My data show that there is an intricate cross-talk between diet and mtDNA where mtDNA …

Physiological role and quantitative aspects of human Nonsense-mediated mRNA decay (NMD)
… NMD has been shown to also regulate normal gene expression and NMD thus emerged as one of the key post-transcriptional mechanisms of gene regulation. Despite the progress in the understanding of the role and mechanism of this pathway, the physiological impact of NMD on humans is not yet fully …

Genetic analysis of Cannabis flowering traits in differential environments
… Cannabis agronomic traits exhibit significant phenotypic variation due to both underlying genetic diversity and environmental heterogeneity. This dissertation describes research aimed at understanding how such traits are shaped and consists of two experimental chapters examining various aspects …

RaSaR: A Novel Methodology for the Detection of Epistasis
… of genetic variants collaborating to produce a phenotypic expression. Epistasis is commonly performed as a pairwise or limitless-arity capacity that considers variant networks as either variant vs variant or as high order interactions. This type of analysis extends the number of tests that were …

Health Behaviors and Physical Health Among Young Adults with Varying Psychometric Schizotypy
… Schizotypy may be conceptualized as the phenotypic expression of increased risk for schizophrenia spectrum disorders, and dimensional models of schizotypy suggest that it varies on a continuum ranging from non-clinical (i.e. low schizotypy) to clinical (i.e. high schizotypy and …

Genetic architecture of reproductive and growth traits in laboratory mice
… contributions of additive variation to the phenotypic expression for body weight were 17.4 and 9.5% of 12-day weights, 33.8 and 5.4% of the 42-day weights, and 32.9 and 29.5% of 56-day weights for males and females, respectively. Gain from 21-42 days of age showed significant additive …

Vegetative tillering plasticity modulates agronomical optimum plant density in winter wheat
… complex due to the tillering trait and its phenotypic variance due to the interaction between genotype and environment (G × E). In this scenario, phenotypic plasticity is an insightful crop ecology perspective to understand G × E. Our objectives were to explore the relations of winter wheat …
