Research ArticleOpen accessIn the abstractWhat is Xenohormesis?Joseph A. Baur, David A. SinclairPolyphenols such as resveratrol and quercetin, which are produced by stressed plants, activate sirtuin enzymes and extend the lifespan of fungi and animals, ostensibly by mimicking the beneficial effects of caloric restriction. This observation raises an interesting question: Why should foreign molecules that are non-nutritive and seemingly unrelated to any endogenous molecule modulate the same biochemical pathways that mediate the … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 10,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractElucidating the Mechanism(s) of Hormesis at the Cellular Level: The Universal Cell ResponsePaul S. AgutterMany environmental stressors elicit biphasic effects from single cells. Such cellular hormesis may be interpreted in terms of (a) the superimposition of simple biochemical processes or (b) the non-specific behaviour of the cell. The latter approach is emphasized in this article and identified with the universal cell response (UCR); however, the importance of identifying molecular-level concomitants of the UCR is … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 13,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Yoga and Traditional Physical Exercise on Hormones and Percentage Insulin Binding Receptor in Patients with Type 2 DiabetesLorenzo Gordon, Errol York Morrison, Donovan McGrowder et al.The objective of the study was to investigate the short-term impact of a brief lifestyle intervention of yoga and traditional Physical Training (PT) exercise regimens on: serum insulin, percentage insulin binding receptor, internalization of insulin-receptor complex, T3, T4, TSH and cortisol at baseline, 3 months and 6 months in patients with type 2 diabetes mellitus. A total of 231 patients … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 8,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies On Bioemulsifier Production by Bacillus licheniformis PTCC 1595Gholamreza D. Noudeh, Mohammad H. Moshafi, Payam Khazaeli, Farideh AkefSurfactants are amphipathic molecules which reduce surface and interfacial tensions and widely used in pharmaceutical, cosmetic, food and petroleum industries. Biosurfactants are the structurally diverse group of surface-active molecules synthesized by microorganisms. There are several advantages for biosurfactants in contrast with chemical surfactants, such as lower toxicity; higher biodegradability; better environmental compatibility; higher foaming; high selectivity and specific activity at … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,282 accessesView PDFCite
Research ArticleOpen accessIn the abstractSesame Oil As A Protective Agent Against Doxorubicin Induced Cardio Toxicity In RatKaneez F. Shad, Suhail Al-Salam, Alaaeldin A. HamzaThe therapeutic value of doxorubicin (DXO) as anticancer antibiotic is limited by its cardiotoxicity. This study aimed to investigate the protective effect of sesame oil against DXO-induced cardiotoxicity and oxidative stress. The administration of DXO (20 mg/kg) to Wister male rats, increased serum aspartate aminotransferase and creatine kinase activities (as cardiotoxicity indices) as well as cardiac malondialdehyde and protein carbonyl … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy the Effects of Ramadan Fasting on the Serum Glucose and Lipid Profile among Healthy Jordanian StudentsKama Mohmoud Saleh MansiRamadan is the holiest month in the Islamic calendar and Muslims fast during this month. We designed this study to evaluate the effect of Ramadan fasting on plasma lipids profile and serum glucose among healthy Jordanian students. Ramadan fasting entails major changes in sleep pattern, physical activity and eating habits, which may cause changes in metabolism both in health and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmetine produce Entamoeba histolytica Death by Inducing a Programmed Cell DeathJ.D. Villalba-Magdaleno, R. Rojas, C. Gómez et al.Amoebiasis is a major public health problem in tropical and subtropical countries. Although a number of antiamoebic agents are used for its treatment and the molecular targets of these drugs have been identified, the biochemical and physiological mechanisms that produce trophozoite death are little known. The present study dates the in vitro induction of programmed cell death (PCD) in E. … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Ethanol Extract of Vinca rosea on Wound Healing in Diabetic RatsShivananda NayakVinca rosea (Catharanthus roseus L.) is native to the Caribbean Basin and has historically been used to treat a wide assortment of diseases. European herbalists used the plant for conditions as varied as headache to a folk remedy for diabetes.
