Research ArticleOpen accessIn the abstractNovel Production of Two New Nonpolyenic Antifungal Macrolide Derivatives by Streptomyces Z26 Isolated from Moroccan Rhizospheric SoilAhmed Nafis, Brahim Oubaha, Najoua Elhidar et al.The aim of our study was to screen Moroccan actinomycete isolates able to produce nonpolyenic antifungal metabolites in order to contribute to limiting the problem of fungal infections emergence in particular mycotic diseases and to discover known antifungal families, especially nonpolyenic drugs. 480 isolates were tested against 5clinically pathogenic Candida species. Several methods have been used to study the polyenic … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 8 Mar 2018 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Silencing of Septin 1 via Synthetic siRNAs in Schizosaccharomyces pombeSemih Ekimler, Merve Yilmazer, Ercan AricanSeptins are evolutionary conserved GTP-binding proteins and form heterooligomers in cells to interact with cytoskeleton. The main roles of septins in cell are cytokines, membrane interactions, vesicle trafficking and microtubule and actin organization. Non-coding RNAs are key players of gene expression regulation. Small-interfering RNAs (siRNAs) belong to non-coding RNAs, are characterized by sequence complementarity to their target mRNAs. siRNAs silence … …OnLine Journal of Biological Sciences, Vol. 17, Issue 1 · 31 Mar 2017 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoltage-Gated Channels as Causative Agents for EpilepsiesMutasem Abuhamed, Xiao Bo, Kun Xia et al.Problem statement: Epilepsy is a common neurological disorder that afflicts 1-2% of the general population worldwide. It encompasses a variety of disorders with seizures. Approach: Idiopathic epilepsies were defined as a heterogeneous group of seizure disorders that show no underlying cause .Voltage-gated ion channels defect were recognized etiology of epilepsy in the central nervous system. The aim of this article … …American Journal of Immunology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Unusual Association between Chromoblastomycosis and Jorge Lobo’s Disease in the Same Patient from the Amazon RegionMaurimelia M. da Costa, Silvia H. Marques da Silva, Hugo J. R. Almeida et al.A clinical case of co-infection Cladophialophora sp. and Lacazia loboi is described and in a same patient with an 18-year history of verrucous plaques and parakeloidal nodular lesions. A 50-yearold man, a laborer, living in the Anajás city, Para, Brazil (rural Amazon region), was seen at the Evandro Chagas Institute’s ambulatory. Histopathological analysis revealed intense hyperplasia and hyperkeratosis of the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 7,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural Evidences of Hepatitis B Infection in Human Liver Biopsies Disclose Complex Assembly and Morphogenesis Pathways for Hepatitis B VirusViviana Falcon, Ivon Menéndez, Nelson Acosta-Rivero et al.Despite of recent advances on acknowledge of hepatitis B virus (HBV) structure and biology, little is known about the morphogenesis and release of virions. In this study, the ultrastructural analysis of HBV components in liver biopsies from chronically HBV-infected patients disclosed complex assembly and morphogenesis pathways for HBV. HBV core (HBcAg) and surface (HBsAg) antigens were specifically identified in all … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrasonographic Apperance of the Gestational Structures Throughout Pregnancy in BitchesA. Aissi, C. SlimaniUltrasonographic examinations of 10 pregnant bitches with known breeding dates were made on successive days to establish the identifiable characteristics of pregnancy. Subsequent serial examinations were made to sonographically characterize normal canine prenatal development based about the first mating. The initial detection of the fetal and extra-fetal structures were as follows: gestational sac at day 17.88±1.13 (16-21); zonary placenta in … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractPharmacophore Pattern Identification of Tachykinin Receptor Selective Peptide Agonists: Implications in Receptor SelectivityAnjali Dike, Indu R. Chandrashekaran, Anil K. Mantha et al.The mammalian tachykinin (TK) peptides and their three Neurokinin (NK1, NK2 and NK3) receptors represent an effector system with wide-ranging actions on neuronal, airway smooth muscle, mucosal, endothelial, immune, inflammatory and remodeling cell function. Recent clinical and preclinical data suggests the pathophysiological role of TKs in various diseases including asthma, emesis and depression. The TK-NK receptor interactions and overlapping functions … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study of Morphological Structure, Phase Structure and Molecular Structure of Collagen-PEO 600K Blends for Tissue Engineering ApplicationN. F. Mohd Nasir, M. G. Raha, N. A. Kadri et al.A new material which is collagen/ poly (ethylene oxide) (PEO) blend was developed to determine its possibility as a promising material for tissue scaffold. PEO with average molecular weight of 600,000 and collagen originated from calf skin were dispersed in 0.1 M acetic acid to prepare a concentration of 1 wt% for PEO and 0.15 wt% for collagen. The collagen-PEO600K … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,422 accessesView PDFCite
