Research ArticleOpen accessEvery word in the title5-Hydroxytryptamine Induces Electrogenic Secretion in the Duodenum of Gerbil (Gerbillus cheesmani)Fawzia Y. Al-BaloolThe effect of serosally added 5-hydroxytryptamine (5-HT 100 µM) on the short circuitcurrent (Isc) across duodenum taken from fed, starved (4 days, water ad lib) and undernourished (50% control food intake for 21 days) gerbils (Gerbillus cheesmani) were investigated. The effect of the neurotoxin, tetrodotoxin (TTX 10 µM) and atropine (100µM) on the maximum increase in Isc induced by 5-HT … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,383 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Use of α-MF Signal Peptide Without Spacer for Producing Insulin Aspart Precursor in Pichia pastoris KM71Popi Asri Kurniatin, Fifi Fitriyah Masduki, Neni Nurainy et al.A spacer peptide (Glu-Ala repeats) connects N-terminal of a polypeptide precursor to the signal peptide of α-mating factor (α-MF) from Saccharomyces cerevisiae. During the polypeptide precursor secretion, the signal peptide will be first cleaved by signal peptidase in the endoplasmic reticulum, followed by Kex2 endopeptidase and finally the spacer peptide is removed by dipeptidyl aminopeptidase in the Golgi apparatus. In … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 31 Oct 2019 · 9,026 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,643 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStructural Characterization at the Atomic Level of a Molecular Nano-Machine: The State of the Art of Helicobacter Pylori Flagellum OrganizationIvana Pulić, Valentina Loconte, Giuseppe ZanottiMotility is fundamental for success in colonization and survival of the human pathogen H. pylori, the bacterium that colonizes about half of the human population. Motility is achieved through flagella. In this review the present structural knowledge about the organization of H. pylori flagella is summarized, considering not only the structure of its proteins, but also what is known about … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 12 Nov 2014 · 8,310 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,170 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Atorvastatin on Oxidized Low-Density Lipoprotein-induced Proliferation, Apoptosis, and Matrix Metalloproteinase-9 Expression in Human MacrophagesBensheng Liu, Huifan Li, Yan Wang, Li ZhangAtorvastatin (ATV), an HMG-CoA reductase inhibitor, is utilized in the treatment of atherosclerotic diseases. Mononuclear Macrophages (MMs) are critical immune cells involved in atherosclerosis progression, participating in processes such as foam cell formation, cytokine secretion, and the development of fibrous cap and lipid core. To further elucidate the mechanism by which ATV exerts its therapeutic effects on atherosclerosis through the … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 18 Nov 2025 · 2,133 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExploring the Role of Vitamin B12 as an Anti-atherogenic and Anti-inflammatory Agent in Apparently Healthy Adults With Hypovitaminosis DShravan Ajith Panchwadkar, Sudha Kuthethur, Sowndarya Kollampare, Neelam Manjunath PawarVitamin B12 deficiency is associated with metabolic changes like methyl malonic acidemia and hyperhomocystinemia eventually leading to atherosclerosis. Dyslipidemia and vitamin D (vit D) deficiency are independent risk factors of CVD. This study aims to explore the interrelationship between inflammatory markers, adverse lipid profile and vitamin B12 in hypovitaminosis D. Since, atherosclerosis is an inflammatory condition we have investigated CRP … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 11 Jul 2025 · 3,326 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHistomorphochemical Studies on Accessory Glands of Iraqi Blackbuck (Caprus Hircus)Waleed J. A. Al-Kelaby, Wafaa Hadi Mousa AL-Hashem, Zahraa S. M. Al Kaabi et al.Thevarious species' male accessory genital glands vary and are intimately relatedto the pelvic urethra. These glands secrete nutritional substances, buffers,and mucous to increase volume, serve as lubricants, reduce the minor acidity ofvaginal contents and make the environment more hospitable to motile sperm. Thisstudy aims to study the histological and histochemical structure of the maleaccessory sex glands in caprine Iraqi breeds. … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 25 Nov 2022 · 5,382 accessesView PDF Cite
