Research ArticleOpen accessIn the author namesEffects of Short Term in vitro Stress Hormone Exposure on Regulatory T Cell Number and Function in AsthmaKristina E. Rehm, Gailen D. Marshall, Jr.Asthma is characterized by alterations in the immune system, including regulatory T cells (Treg). Further alterations in Treg numbers and/or function caused by stress hormones may be a contributing factor in asthma pathogenesis. We compared Treg populations and the effects of Dexamethasone (DEX, a laboratory analog of cortisol) on Treg cell number and function in patients with asthma and a … …American Journal of Immunology, Vol. 11, Issue 1 · 24 Apr 2015 · 6,608 accessesView PDFCite
Research ArticleOpen accessIn the author namesCOLLABORATION OF STATISTICAL METHODS IN SELECTING THE CORRECT MULTIPLE LINEAR REGRESSIONSAli Hussein Al-MarshadiThis article considers the analysis of Multiple Linear Regressions (MLRs) that are essential statistical method for the analysis of medical data in various fields of medical research like prognostic studies, epidemiological risk factor studies, experimental studies, diagnostic studies and observational studies. An approach is used in this article to select the "true" regression model with different sample sizes. We used … …Current Research in Biostatistics, Vol. 4, Issue 2 · 15 Sep 2014 · 7,791 accessesView PDFCite

Research ArticleOpen accessIn the author namesEFFECT OF REPLACING CORN AND SOYBEAN MEAL WITH BREWERS RICE AND DRIED DISTILLERS BREWERS YEAST ON PERFORMANCE OF GROWING-FINISHING PIGSOndieki Gekara, Talesha Dokes, Renita MarshallThe objective of this study was to determine the effect of replacing corn and Soybean Meal (SBM) with Brewers Rice (BR) and Dried Distillers Brewers Yeast (DDBY), respectively, on ADG, G:F, Apparent Total Tract Digestibility (ATTD), fecal DM output and fecal loss of N and P of growing-finishing pigs. Sixty four Yorkshire x Duroc x Hampshire crosses (BW = 73±5.7 … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 2 · 24 Apr 2014 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the author namesDiet Modification to Reduce Fecal Excretion of Nitrogen and Phosphorus in Growing-Finishing PigsOndieki Gekara, Talesha Dokes, Renita MarshallAn experiment was conducted to determine whether brewers rice can replace all corn in diets for swine and reduce fecal excretion of Nitrogen (N) and Phosphorus (P) without compromising performance and carcass quality of growing-finishing pigs. Sixteen Yorkshire x Duroc x Hampshire crosses (BW = 77±2.5 kg) were randomly assigned to either corn/soybean meal (CSM; control) or brewers rice/soybean meal … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 3 Oct 2013 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the author namesNutritional Strategies to Mitigate the Effects of Negative Energy Balance on Reproductive Performance of Early Postpartum DoesOndieki Gekara, Renita MarshallThe objective of this study was to research nutritional strategies to mitigate the effects of Negative Energy Balance (NEB) on reproductive performance of early postpartum does. Twenty seven does in their second week of lactation and their kids were randomly assigned to three levels of supplement diet, replicated three times. The diets were: (1) Low Energy/Protein supplement level (LEP; Control), … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 29 Dec 2012 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the author namesMixed Species Grazing of Cattle and Goats on Gastrointestinal Infections of Haemonchus ContortusRenita Marshall, Sebhatu Gebrelul, Lisa Gray, Yemane GhebreiyessusAt the present time, the meat of goat is the fastest growing class of livestock in the U.S.A. Due to the sub-tropical climate in the South Eastern region of the US, internal parasites pose a major constraint to the industry. The blood-feeding nematode, Haemonchus contortus results in production losses and even death in untreated animals.

Research ArticleOpen accessIn the author namesAcquired Immune Deficiency Syndrome, Risky Sexual Behavior and AbortionMarshall H. MedoffProblem statement: incidence of abortion in the United States has steadily declined since 1990. The question is why? Approach: This study, using multiple linear regression, examines whether women’s unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected) … …Journal of Social Sciences, Vol. 8, Issue 2 · 28 Feb 2012 · 8,538 accessesView PDFCite
Research ArticleOpen accessIn the author namesNew Procedure to Improve the Order Selection of Autoregressive Time Series ModelAli Hussein Al-MarshadiProblem statement: We propose new approach could be used to guide the selection of the "true" order of autoregressive model for different sample size. Approach: We used simulation study to compare four model selection criteria with and without the help of the new approach. The comparison of the four model selection criteria was in terms of their percentage of number … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 14 Sep 2011 · 7,259 accessesView PDFCite
