ALBarakawi and Alqundeila. The extracted oil from ALBarakawi seeds weighed 6.833% w/w oil, Alqundeila oil extracted weighed 5.064% w/w. Approach: The physical properties of ALBarakawi oil were: viscosity: 17cp, refractive Index: 1.444, density: 0.9116 g cm-3 color: … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 5 May 2012 · 9,500 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeroin-Induces Differential Protein Expression by Normal Human Astrocytes (NHA)Jessica L. Reynolds, Supriya D. Mahajan, Donald Sykes, Madhavan P.N. NairHeroin use is postulated to act as a cofactor in the neuropathogenesis of human immunodeficiency virus (HIV-1) infection. Astrocytes, integral components of the CNS, are reported to be susceptible to HIV-1 infection. Upon activation, astrocytes release a number of immunoregulatory products or modulate the expression of a number of proteins that foster the immunopathogenesis of HIV-1 infection. However, the role … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,261 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Vitamin A on Growth Performance, Antioxidant Status and Blood Constituents in Lactating Grey GoatWeiren Yang, Ping Wang, Yuanqiang Jing et al.Problem statement: It is regarded that vitamin A protects cells from damage by radicals which are believed to contribute to certain chronic diseases and regulates immune function of animals by protection of mucosal epithelium acting as the first defense barrier. All these properties of vitamin A may be attributable to its antioxidant activity. This study was to evaluate the effects … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlpha Thalassemia Carrier Detection a Diagnostic ApproachH. R. Samruddhi, Anupama Hegde, Harsha Prasada L et al.Alpha-thalassemia is one of the most common single-gene disorders, and its carrier state often remains undetected due to nonspecific hematological findings. This study aimed to identify alpha-thalassemia carrier status among people being investigated for hemoglobinopathy in a tertiary care setting. A cross-sectional laboratory-based study was conducted from January 2023 to January 2024. Hemoglobin variant analysis reports by High Performance Liquid … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Sep 2026 · 481 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnveiling the Potential of Dombeya buettneri K.Schum As a Drug Agent: Molecular Docking of Compounds With Enzymes Linked to Diabetes and Neurodegenerative DiseaseEsther Emem Nwanna, Samuel Chima Ugbaja et al.This study investigated the mechanisms of Dombeya buettneri (snowball leafy) extracts on diabetes, hypertension, and neurodegenerative diseases. It compared extracts obtained using steep water (a by-product of corn wet milling) and aqueous water. The extracts were analyzed for total phenol, total flavonoid content, antioxidant activities such as FRAP, ABTS, NO, DPPH, iron-induced lipid peroxidation assay, degradation of deoxyribose (Fenton’s reaction), … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Feb 2026 · 2,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated. This study determined the acaricidal activity of A. indica and C. papaya leaf extract against R. sanguineus, both individually and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Apr 2025 · 8,409 accessesView PDFCite
