Research ArticleOpen accessIn the abstractDihydroartemisinin-Stimulated Hyperplasia of Rat Lung Smooth MusclesUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Dihydroartemisinin was shown to produce two types of inhibitory effects on the cardiac muscles of rats. It was also shown to stimulate haemopoiesis in the lungs, liver, spleen, intestine and kidney of rats. This study attempted to find out the nature of the effect of oral dihydroartemisinin on the lungs of Wistar albino rats. Approach: The effects of … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 8 Dec 2011 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractGinger Supplementation Enhances Working Memory of the Post-Menopause WomenNaritsara Saenghong, Jintanaporn Wattanathorn, Terdthai Tong-Un et al.Problem statement: Cognitive impairment is one important problem in post-menopausal women. Although hormone therapy can improve this condition, it also produces adverse effect. Recent findings showed that this condition could be mitigated by the herb. Ginger or Zingiber officinale Roscoe, a plant in a family of Zingiberaceae, was previously demonstrated the neuroprotection and cognitive enhancing effects. Therefore, this study was … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 10,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractBasal Salt Requirements Differ According to Culture Stage and Cultivar in Date Palm Somatic EmbryogenesisJameel M. Al-KhayriProblem statement: Various media formulations differing in basal salt composition are arbitrary selected to provide essential nutrients for plant in vitro cultures. Evidence suggests that in vitro response to various media formulations varies among genotypes and depends on the culture stage. This study examined the efficacy of five basal salt formulations on callus growth and somatic embryogenesis in date palm … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 1 · 27 May 2011 · 10,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Diagnosis of Breast Cancer using Molecular, Biochemical and Pathological MarkersSalah El-Din El-Assal, Adel A. El-Tarras, Samir M. Abd-allaProblem statement: Laboratory diagnosis of breast cancer in most of the hospitals has traditionally been performed using cell culture and the direct hormone receptor assay, which are money and time consuming. Approach: This study was performed in order to direct the attention toward increasing the efficiency of early diagnosis in clinical laboratories at the western region of KSA and Egypt … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,060 accessesView PDFCite
Research ArticleOpen accessIn the abstractZinc Deficiency and Associated T-Cell Dysfunctioning among Human Immunodeficiency Virus SeropositivesM. Andrew Pradeep, M. Thiruvalluvan, V. Nalini, J. Stella MaryProblem statement: All the nutrients in the diet play a crucial role in maintaining an optimal immune response. In both, deficient and excessive intake of nutrients can have negative consequence on the immune status and susceptibility to a variety of pathogens. Zinc is an essential micronutrient for human growth development and immune function. It plays a vital role in structure … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 8,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cooling and Supplemental Bovine Somatotropin on Milk Production relating to Body Glucose Metabolism and Utilization of Glucose by the Mammary Gland in Crossbred Holstein CattleSiravit Sitprija, Somchai Chanpongsang, Narongsak ChaiyabutrProblem statement: The low milk yield and shorter persistency of lactation of dairy cattle is the major problem for the dairy practices in the tropics. High environmental temperatures and rapid decline of plasma growth hormone level can influence milk production. Regulation of the milk yield of animals is mainly based on the mechanisms governing the quantity of glucose extracted by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,346 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling A Multi-Compartments Biological System with Membrane ComputingRavie Chandren Muniyandi, Abdullah Mohd. ZinProblem statement: Most of the biological systems have been hierarchical in structure with processes interacting between different compartments. Membrane computing formalism has provided modeling capabilities in representing the structure of biological systems. Approach: This study was carried to investigate the modeling of a multi-compartment biological system by using membrane computing formalism. The hormone-induced calcium oscillations in liver cells which was … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Metabolism Studies of Polybrominated Diphenyl Ethers Using Rat and Human Liver MicrosomesShun Wen Cheng, Kathleen Randall, Anne T. KotchevarA number of studies have recently reported the bioaccumulation of the commonly used fire retardants, Polybrominated Diphenyl Ethers (PBDEs), in humans and wildlife. Exposure of animals to PBDEs has been shown to result in developmental neurological, reproductive abnormalities and the disruption of endocrine function. Thyroid hormone equilibria was also shown to be altered by PBDE exposure. There is evidence that … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,999 accessesView PDFCite

Yang et al.Problem Statement: The efficacy of Methionine (Met) sparing effect of Betaine (BET) has been shown to be associated with dietary compositions, animal physiological stage and living conditions. This study was to determine the extent to which dietary Met could be replaced by BET in broiler chickens under the feeding conditions specific to Chinese poultry industry.Approach: A total of 900 day-old … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 14,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic and Non-Hormetic Dose-Response Functions in Stress Effects on Memory and Synaptic Plasticity: Issues and MechanismsPhillip R. Zoladz, David M. DiamondOver a century of behavioral research has shown that stress can exert both positive and negative effects on memory. We have explored the idea that the complex effects of stress on learning and memory can be characterized by hormetic- and non-hormetic dose-response functions, in which stress may either stimulate or impair brain memory mechanisms, depending, in part, on the timing … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,188 accessesView PDFCite
