Research ArticleOpen accessIn the keywordsPOTENTIAL AMELIORATIVE ROLE OF N-ACETYLCYSTEINE AGAINST TESTICULAR DYSFUNCTION INDUCED BY TITANIUM DIOXIDE IN MALE ALBINO RATSAhmed Farag El-Kirdasy, Mohamed Abdo Nassan, Ahmed Abdel Aziz Baiomy et al.In this study, we examined the ameliorative action of N-Acetylcysteine (NAC) against Titanium Dioxide (TiO2) induced testicular degeneration in albino rats. Adult male albino rats were given saline as a control group, TiO2 (1200 mg kg-1 BW), NAC (100 mg kg-1 BW) and co-treatment of NAC and TiO2 as a protective group for 3 months. Testicular tissues were extracted for … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 31 Dec 2013 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Virgin Olive Oil (Olea europea. L) on Kidney Function Impairment and Oxidative Stress Induced by Mercuric Chloride in RatsYoucef Necib, Ahlem Bahi, Sakina Zerizer et al.The study was designed to investigate the possible protective role of virgin olive oil in mercuric chloride induced renal stress, by using biochemical approaches. The effects of virgin olive oil on mercuric chloride induced oxidative and renal stress were evaluated by serum creatinine, urea and uric acid levels, kidney tissue lipid peroxidation, GSH levels, GSH-Px and GST activities. Administration of … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 16,791 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLaser Therapy of Irradiated Traumatized Skeletal Muscles and State of Immune System in AnimalsNelly Bulyakova, Svetlana Zubkova, Valentina AzarovaProblems statement: This study was designed to examine the effect of laser therapy on regeneration of traumatized skeletal muscles and on dynamics of immune responses in thymus and bone marrow under ionizing radiation. Approach: After local X-ray radiation of both rat gastrocnemius muscles at a dose 20 Gy or after total γ-irradiation of animals at a semiletal dose 6 Gy, … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 27 Aug 2011 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIdentification a Novel Raw-Starch-Degrading-α-Amylase from a Tropical Marine BacteriumZeily Nurachman, Alfredo Kono, Ocky Karna Radjasa, Dessy NataliaProblem statement: Bacteria from the surface of the tropical marine hard coral Acropora sp. were screened for producing raw-starch-degrading-α-amylase. Approach: Based on its 16s rDNA sequence, a bacterium that produced the highest amylolitic activity was identified as Bacillus amyloliquifaciens ABBD. The bacterial isolate secreted a α-amylase extracellularly and then the enzyme was partially purified by ammonium sulfate precipitation followed by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,337 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBioethanol Production from Rice StrawNutawan Yoswathana, Phattayawadee Phuriphipat, Pattranit Treyawutthiwat, Mohammad Naghi EshtiaghiProblem statement: Rice straw has been treated with different chemical (acid, alkali) and physical (subcritical water, ultrasound) methods to convert lignocellulose material to sugar. In addition enzyme treatment of pretreated samples has been applied to improve the conversion of lignocellulose material in sugar. Approach: Sulfuric acid at concentration of 1-9% was applied for acid treatment. For alkali treatment was sodium … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 18,065 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,478 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Super Absorbent Application on Antioxidant Enzyme Activities in Canola (Brassica napus L.) Cultivars under Water Stress ConditionsH. R. Tohidi-Moghadam, A. H. Shirani-Rad, G. Nour-Mohammadi et al.Problem statement: Drought stress significantly limits Canola (Brassica napus L.) growth and crop productivity. Hence, efficient management of soil moisture and study metabolic changes which occur in response to drought is important for agricultural production of this Crop. Approach: For a better understanding of drought tolerance mechanisms and improving soil water content management strategies, an experiment was laid out in … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,607 accessesView PDFCite
