Fort Valley State University is a historically black university located in Fort Valley, Georgia. It is also a unit of the University System of Georgia and a member-school of the Thurgood Marshall College Fund. Fort Valley is approximately 100 miles south of Atlanta, 25 miles south of Macon,18 miles west of Warner Robins, and 15 miles north of Perry.As the only 1890 land-grant university in Georgia, Fort Valley State University is a comprehensive institution that provides an education to over 4,000 students. The student body is currently approximately 91% of African-American descent. The average age of undergraduates is 24 and the average age of graduates is 33. Roughly one-third of the students live on-campus and 85 percent of the student body are full-time students.The University is located in the town of Fort Valley in Peach County, the original site of the nation's peach industry. Its 1,365 acre campus is the second-largest in area for a public university in the state. Wikipedia.

Hemoglobin (Hb) and Packed Cell Volume (PCV) values were compared in blood collected from the following four sites of the Japanese quail: jugular, brachial, medial metatarsal veins and the heart. Ten 25-week-old hatch-mate layers of similar body weight having a hard shelled egg in the uterus were used in this study. Hb and PCV values were found to be the highest in the medial metatarsal vein followed by, in descending order, the brachial vein, the jugular vein and the heart. The heart had significantly lower values (p<0.05) compared with the jugular, brachial and medial metatarsal veins with the latter two having almost similar values. Blood samples from the jugular vein exhibited the least variability compared to other sites. The brachial vein followed by the jugular vein, were found to be suitable sites for blood sampling as well as for making injections without any significant complication. The heart puncture technique was very risky, traumatic and resulted in many side effects and should not be used, particularly in on-going experiments. Scientists should be aware of possible differences in blood constituents as a result of sampling sites. For obtaining accurate and reliable results, these points should be taken into consideration while designing an experiment or assessing comparative hematological data collected using different collection techniques. © Asian Network for Scientific Information, 2010.

The potential for integrating the application of Heterorhabditis indica Poinar, Karunakar, and David (Homl strain) and release of Habrobracon hebetor (Say) in the management of the Indianmeal moth, Plodia interpunctella (Hübner), was investigated in the laboratory. A combination of the nematode and the parasitoid was observed to increase the mortality of P. interpunctella. The interaction between the nematodes and parasitoids was not antagonistic but could possibly be additive or synergistic. Release of parasitoids or application of nematodes alone generated between 62.25% and 71.25% mortality of the P. interpunctella larvae whereas combination of the two resulted in 98.0-99.25% mortality. The nematode was found to be virulent to the larvae of the parasitoid but not to the pupae and the adults. Adult female parasitoids that were exposed to both uninfected and nematode-infected P. interpunctella larvae in a free-choice arena were unable to distinguish between the two. In contrast, infective juvenile nematodes preferentially infected parasitized host larvae compared with healthy non-parasitized host larvae. Nematode reproduction was not significantly different in parasitized and non-parasitized host larvae. The combined application of H. indica and H. hebetor for the control of P. interpunctella may be beneficial if the detrimental effects of the nematode on the parasitoid can be minimized through optimum timing. © 2010 Elsevier Inc.

A series of novel piperidine ring modified analogs of (±)-threo- methyl phenyl (piperidin-2-yl)acetate was synthesized by direct alkylation and reductive amination procedure, using sodium borohydride over molecular sieves. The chemical structures of these compounds were established based on mass spectra, 1H NMR spectra, and CHN elemental analysis data. Several significant modifications in the literature methodologies were made to make the reaction more efficient, and good yields were generally obtained. Copyright © Taylor & Francis Group, LLC.

Itk is a member of the Tec family tyrosine kinases involved in T-cell receptor signaling. The authors review the background and most recent findings of the role of Itk T-cell activation and development of αβ T cells. They also discuss the role of Itk in development of nonconventional T cells, including CD8 + innate memory phenotype T cells, different γ δ T-cell populations, and invariant NKT cells. They close by reviewing the regulation of T helper differentiation and cytokine secretion, the immune response to infectious disease, and diseases such as allergic asthma and atopic dermatitis by Itk.

Accumulating evidence from recent studies has suggested a possible link between exposure to environmental pesticides and obesity. In this study, we assessed the potential associations between exposure to dichlorophenol pesticides and obesity in adults. Study participants aged 20-85 years were selected from the 2005 to 2006 and 2007 to 2008 U.S. National Health and Nutrition Examination Survey, and were categorized as obese and non-obese based on body mass index. Creatinine-corrected urinary concentrations of dichlorophenols were determined to assess level of exposure to environmental pesticides. Multivariate logistic regression was performed using SAS 9.3 to assess the association between 2,4-dichlorophenol (2,4-DCP) and 2,5-dichlorophenol (2,5-DCP) levels in urine and obesity with adjustment for potential confounders. Significantly higher geometric means of urinary concentrations of both 2,5-DCP (p<. 0.0001) and 2,4-DCP (p= 0.0170) were seen in obese adults, compared to that in non-obese adults. A dose-dependent increase in the prevalence of obesity was observed in the study participants across increasing levels of urinary 2,5-DCP (p-trend. <. 0.0001). Urinary concentrations of 2,5-DCP were significantly associated with obesity among the second (AOR: 1.47, 95% CI: 1.12, 1.93), third (AOR: 1.41, 95% CI: 1.07, 1.87), and fourth (AOR: 1.62, 95% CI: 1.21, 2.17) inter-quartiles after adjustment for age, gender, race, education, total fat intake, and physical activity. A statistically significant association was not seen between urinary 2,4-DCP and obesity. Our findings suggest a potential relationship between exposure to the fumigant insecticide paradichlorobenzene, measured as urinary concentrations of 2,5-DCP, and obesity in adults. Because we cannot rule out the possibility of reverse causality in our study, prospective studies measuring exposure during etiologically relevant periods are warranted. © 2013 Elsevier GmbH. Source
