EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdaptogenic Potentials of Cyphostemma glaucophilla Aqueous Leaf ExtractOjogbane Eleojo, Nwodo Okwesili Fred Chiletugo, Omale JamesCytophostemma glaucophilla aqueous extract is used in Kogi and Kwara States of Nigeria to treat Kwashiorkor and to boost immunity. As part of the effort to evaluate its effect on stress, it was screened for adaptogenic potentials. This investigation was conducted using albino rats to determine the ability of this plant to increase non specific resistance against physical, biological and … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 3 · 4 Sep 2013 · 7,118 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSome Effects of Abiotic Stress on Infection of Dyer’s Woad (Isatis tinctoria L.) by Puccinia thlaspeos C. Schub.: Implications for Biological ControlElizabeth Thomas, Bradley Ray KroppProblem statement: The rust pathogen, Puccinia thlaspeos, is being studied as a potential biocontrol agent for the noxious weed dyer’s woad. Although its disease etiology is well understood, very little has been learned about the effect of environmental stresses on infection. Approach: Dyer’s woad plants were exposed to different levels of oxidative stress, salinity stress, osmotic stress, dehydration, and cold … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,715 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudies on Wound Healing and Antiulcer Activities of Extract of Aerial Parts of Phyllanthus niruri L. (Euphorbiaceae)C. O. Okoli, A. C. Ezike, P. A. Akah et al.Problem statement: Phyllanthus niruri is widely used in many parts of the world to manage a wide range of diseases. As part of efforts to elucidate its pharmacological activities and hence medicinal potential, we studied the wound healing and antiulcer properties of extract of the aerial parts using experimentally-created wounds and ulcers in rodents. Approach: Wound healing effect was assessed … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 10,091 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThree Mild Stresses Known to Increase Longevity in Drosophila melanogaster Flies do not Increase Resistance to Oxidative StressÉric Le BourgExposure to a mild stress at a young age (hypergravity, cold or heat) increases longevity and resistance to heat shocks in Drosophila melanogaster flies and it may also delay behavioral aging and increase resistance to other stresses. The effect of these mild stresses on resistance to oxidative stress has not been studied. Flies were thus fed on a saccharose solution … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,301 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCortisol Response Mediates HIV-1-Related Cognitive Deficits Among Injecting Drug AbusersRaymond L. Ownby, Drenna Waldrop-Valverde, Adarsh M. Kumar et al.The cortisol response is an important measure of the endocrine activity to environmental challenges and has been related to cognitive function and mood. Previous studies have shown that the cortisol response to stress is dysregulated in persons with HIV-1 infection. Since cortisol is neurotoxic and its levels have been related to cognitive dysfunction in various disorders, it is possible that … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,759 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Shot Peening and Polishing on the Pitting Corrosion Resistance of Stainless SteelOmar Badran, Naser Kloub, Musa Musa Al-TalAn experimental work was performed to study one of the major problems encountered in industry (i.e., pitting corrosion), which cost the industrial world billions of dollars every year. Stainless Steel 304L sheets were used in the present study, the main reason for using stainless steel is their corrosion resistance and it is the most widely used in process industries, but … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,328 accessesView PDF Cite
