Roukos, K. Papanikolaou, S. Kandrelis et al.Problem statement: The objective of this study was to evaluate the production and nutrition quality of grasslands and kermes oak shrublands in Preveza Prefecture, northwest Greece. Approach: The study involved the collection of herbage and browse samples along a grazing period, from March to October for two consecutive years. In consequence, browse samples were manually separated to leaves and twigs. … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoxp3-Mediated Immunity of Human Pancreatic Cancer Cell Line PANC-1Renxi Wang, Gencheng Han, Jianan Wang et al.Problem statement: More and more evidences have shown that human cancer cells can express Foxp3, the regulatory T cell-associated transcription factor. The role of Foxp3 in human cancer cells is still unclear. We detected Foxp3 expression in human pancreatic cancer cell line PANC-1. SiRNA assays showed that Foxp3 expression suppressed the expression of TGF-β and IL-10 which could induce immune … …American Journal of Immunology, Vol. 5, Issue 4 · 11 Jan 2010 · 7,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotent Antielastase and Antityrosinase Activities of Astilbe chinensisSeung-Hun Lee, Sandesh Sancheti, Shruti Sancheti, Sung-Yum SeoProblem statement: In the current scenario, photo-aging is a major problem causing skin wrinkling and hyperpigmentation. Therefore, elastase and tyrosinase inhibitors play an important role in the treatment of skin aging and thus, gaining a special attention in cosmetic industries. Approach: In the screening of Korean medicinal plants to search the potent elastase and tyrosinase inhibitors, the extract of the … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractStressors Influence on Salmonella enterica Serovar Enteritidis Colonization in BroilersE. S. Soliman, E. Taha, K. D. Infante et al.Problem statement: Poultry industry usually exposing birds to a variety of actions and stressors includs fasting for gastrointestinal emptying before transportation and where birds are often exposed to high environmental temperature during the summer months. These environmental stressors may have influences on bird performance and susceptibility to pathogens such as Salmonella enteritidis by altering the intestinal micrbiota and changes in … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 12 Sep 2009 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrug Interaction between Salinomycin and Exogenous Adrenaline in DogsHamid Rajaian, Javad Sajedianfard, Saeed Nazifi, Ali Moosavi KianProblem statement: Salinomycin is a member of ionophore compounds that may be used in ruminants and pigs as growth promoter or to prevent coccidiosis. There are some reports with respect to the in vitro and in vivo sympathomimetic cardiovascular effects of salinomycin. Available reports indicate that adrenergic impact of the ionophore is brought about by an increase in the secretion … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 2 · 30 Jun 2009 · 7,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Flavonoid, Quercetin, Inhibits HIV-1 Infection in Normal Peripheral Blood Mononuclear CellsMadhavan P.N. Nair, Zainulabedin M. Saiyed, Nimisha H. Gandhi, C. N. RamchandProblem statement: Flavonoids and related polyphenols, have been known to possess cardioprotective, anti-tumor, anti-inflammatory, anti-allergic and anti-viral activities. Previous studies have shown that flavonoid, quercetin significantly downregulates expression of pro-inflammatory cytokines in cultured cells via modulation of NFκB and p38MAPK signaling pathways. In the current study, we hypothesize that quercetin exerts anti-HIV activity by differential modulation of pro-and anti-inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 12,184 accessesView PDFCite
