The Clinical Utility Of Concomitant Pten And Fas Deletion As An Early Indicator For Prostate Adenocarcinoma Subtypes That Lead To Extracapsular Metastasis, Brendan J. Coulter, Phillip Harries

Electronic Theses & Dissertations

The utility of genes PTEN and FAS as prognostic markers for the identification of early and/or aggressive prostatic adenocarcinomas is seemingly validated in the study results we obtained using fluorescence in-situ hybridization (FISH) of archived paraffin embedded surgical prostate core biopsy samples obtained from two CLIA and CAP licensed anatomical pathology labs (Bostwick Laboratories, Uniondale, NV and GoPath Laboratories, Buffalo Grove, IL). From early benign subsets of sample cases to aggressive extracapsular invasive tumors, the presence of random deletions evolves into clonal populations of co-deletion of both genes at question. We identify independent research that demonstrates the ability of these …

Asian/White Differences In The Relationship Of Maternal Age To Low Birth Weight: Analysis Of The Prams Survey, 2004–2011, Sangmi Kim Dec 2016

Asian/White Differences In The Relationship Of Maternal Age To Low Birth Weight: Analysis Of The Prams Survey, 2004–2011, Sangmi Kim

Asian/Pacific Island Nursing Journal

This study aimed to examine (a) maternal age patterns of low birth weight (LBW; birth weight < 2,500 g) for non-Hispanic (N-H) Asian and N-H White women, and (b) Asian–White gaps in LBW risk by maternal age and their mechanisms. Logistic regression analyses were performed on the Pregnancy Risk Assessment Monitoring System data of N-H Asian and N-H White women who delivered their first singleton birth without birth defects in 13 states between 2004 and 2011. Age- and race/ethnicity-specific LBW risk was estimated, unadjusted and adjusted for maternal risk factors (e.g., marital status, maternal education, pregnancy intention, stress, maternal morbidities, smoking, and prenatal care) and their interactions with maternal age or race/ethnicity. The interaction between maternal age and race/ethnicity was statistically significant (p < .0001) with covariates and interactions held constant. N-H Asian women showed a reverse W-shaped maternal-age pattern of LBW with the highest risk in their late 30s (OR = 1.56, 95% CI [1.26, 1.94]) whereas N-H White women experienced a maternal age-related increase in LBW. N-H Asian women were more likely to deliver LBW infant than their N-H White counterparts between their late 20s and late 30s, with the greatest racial/ethnic gap in their late 20s (OR = 4.19, 95% CI [3.33, 5.29]). Preventive strategies should be developed targeting N-H Asian women aged 25 to 39 years to reduce the Asian–White disparities in LBW. Considering the known maternal risk …

International Journal of Aquatic Research and Education

Twenty-six Japanese women (70.5 yr) self-selected water exercise (WEX) (n=13), or control (CON) (n=13) for 12 weeks. WEX was performed 60-minutes/day, 3 days/week with warm-up, cool-down stretch, ADL exercises, and cardiovascular/muscular endurance in 30°C water at a xiphoid level depth. CON continued their current activity/nutrition patterns. Compared to CON, WEX improved (p<.05) functional fitness and balance measures including arm curl (22%), chair stand (21%), 8-feet up & go (13%), chair sit/reach (50%), and 12-min walk (15%). No significant changes in sway velocity (SV) or limits of stability (LOS) were seen for either group. This shallow water exercise improved land-based ADL for older women but not balance. ADL tasks associated with balance did improve which may have indicated enhanced motor control.

Faculty Publications, Biological Sciences

Background Acanthamoebidae is a “family” level amoebozoan group composed of the genera Acanthamoeba, Protacanthamoeba, and very recently Luapeleamoeba. This clade of amoebozoans has received considerable attention from the broader scientific community as Acanthamoeba spp. represent both model organisms and human pathogens. While the classical composition of the group (Acanthamoeba + Protacanthamoeba) has been well accepted due to the morphological and ultrastructural similarities of its members, the Acanthamoebidae has never been highly statistically supported in single gene phylogenetic reconstructions of Amoebozoa either by maximum likelihood (ML) or Bayesian analyses. Results Here we show using a phylogenomic approach that the Acanthamoebidae is …

Natal Host Plants Can Alter Herbivore Competition, Huipeng Pan, Evan L. Preisser, Qi Su, Xiaoguo Jiao, Wen Xie, Shaoli Wang, Qingjun Wu, Youjun Zhang

Biological Sciences Faculty Publications

Interspecific competition between herbivores is widely recognized as an important determinant of community structure. Although researchers have identified a number of factors capable of altering competitive interactions, few studies have addressed the influence of neighboring plant species. If adaptation to/ epigenetic effects of an herbivore's natal host plant alter its performance on other host plants, then interspecific herbivore interactions may play out differently in heterogeneous and homogenous plant communities. We tested wether the natal host plant of a whitefly population affected interactions between the Middleeast Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species of the whitefly Bemisia tabaci by …

Cytochrome C Can Form A Well-Defined Binding Pocket For Hydrocarbons, Levi J. Mcclelland, Harmen B. Steele, Frank G. Whitby, Tung-Chung Mou, David Holley, J B. Ross, Stephen R. Sprang, Bruce E. Bowler

Biological Sciences Faculty Publications

Cytochrome c can acquire peroxidase activity when it binds to cardiolipin in mitochondrial membranes. The resulting oxygenation of cardiolipin by cytochrome c provides an early signal for the onset of apoptosis. The structure of this enzyme-substrate complex is a matter of considerable debate. We present three structures at 1.7-2.0 Å resolution of a domain-swapped dimer of yeast iso-1-cytochrome c with the detergents, CYMAL-5, CYMAL-6, and ω-undecylenyl-β-d-maltopyranoside, bound in a channel that places the hydrocarbon moieties of these detergents next to the heme. The heme is poised for peroxidase activity with water bound in place of Met80, which serves as the …

The Replication Initiator Of The Cholera Pathogen’S Second Chromosome Shows Structural Similarity To Plasmid Initiators, Natalia Orlova, Matthew Gerding, Olha Ivashkiv, Paul Dominic B. Olinares, Brian T. Chait, Matthew K. Waldor, David Jeruzalmi

Publications and Research

The conserved DnaA-oriC system is used to initiate replication of primary chromosomes throughout the bacterial kingdom; however, bacteria with multipartite genomes evolved distinct systems to initiate replication of secondary chromosomes. In the cholera pathogen, Vibrio cholerae, and in related species, secondary chromosome replication requires the RctB initiator protein. Here, we show that RctB consists of four domains. The structure of its central two domains resembles that of several plasmid replication initiators. RctB contains at least three DNA binding winged-helix-turn-helix motifs, and mutations within any of these severely compromise biological activity. In the structure, RctB adopts a headto- head dimeric configuration …
