Research ArticleOpen accessIn the abstractA Case of Refractory Salmonella Spondylodiscitis in an Immunocompetent Patient Treated Via an Extracavitary Approach, Corpectomy and Placement of Expandable CageKimon Bekelis, Oren Gottfried, Zyia L. Gokaslan et al.Problem statement: Salmonella spondylodiscitis is a rare condition that is more prevalent in patients with sickle cell disease or immunosuppression. However, it can also be found in immunocompetent patients. It usually responds well to proper antibiotics. However, surgery is rarely indicated when the infection is refractory to antibiotics, the spine is destabilized or there is an epidural component that is … …American Journal of Infectious Diseases, Vol. 6, Issue 2 · 30 Jun 2010 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractInhibition of Sphingolipid Biosynthesis in Cultured Cells Enhances the Oligosaccharide Production from Exogenous Artifical SubstrateTomohisa Kato, Maria Carmelita Z. Kasuya, Kenichi HatanakaThe effect of fumonisin B1 which is an inhibitor of ceramide synthesis on saccharide elongation of dodecyl β-lactoside (Lac-C12), which is the analogue of lactosyl ceramide (LacCer), in mouse melanoma B16 cells and African green-monkey kidney (Vero) cells was examined. By adding fumonisin B1 in the culture medium used for glycosylation of Lac-C12, mouse melanoma B16 cells synthesized GM3-type analogue … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractMean Age of Menarche in Trinidad and Its Relationship to Body Mass Index, Ethinicity and Mothers Age of MenarcheEdward O. Uche-Nwachi, A. Odekunle, Johann Gray et al.Menarche is the first menstrual period. It is the final event in the physical manifestation of gonadal development. A study in Europe found that the median age of menarche was 12 years and 11 months and that by the tenth year, 0.8% of the girls had their first menses, while the figure for the eleventh and twelfth years were 3.6 … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 8,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractHIV Medication Adherence and Substance Use: The Smartest Women’s ProjectEliot Lopez, Deborah L. Jones, Mary Ishii et al.Antiretroviral (ARV) medication for substance users has been a controversial issue with respect to whether current substance users can successfully maintain their medication regimens. This study compared ARV adherence across current substance users, former substance users and those with no history or current use and the relative impact of a medication adherence intervention on all three groups. Of the 481 … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractSexual Risk Intervention In Multiethnic Drug And Alcohol UsersDeborah L. Jones, Stephen M. Weiss, Ndashi Chitalu et al.An estimated 38.6 million persons globally are living with HIV, of whom over 1.1 million reside in Zambia. Of the 2 million cases in the US, 64% of new cases among women are among African Americans. Alcohol and drug use represents a significant risk factor for HIV transmission among both Zambians and African Americans. In addition, gender dynamics in both … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Cassava (Manihot esculenta) Foliage Supplementation to Calves on the Viability and Egg Count of Haemonchus contortus NematodesJuan López, Esteban Machín, Arturo Zentella et al.Thirty early-weaned 5±3 month-old calves with an average body weight of 96±23 kg were used; 24 were artificially infested with 90 larvae (L3), of H. contortus per kilogram body weight. Calves grazed on African Star Grass (Cynodon plectostachyus) from 0600 to 1300 hours. Grazing was supplemented with lucerne hay (Medicago sativa) or cassava foliage (Manihot esculenta), and 500 g-1 head-1 … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethylenetetrahydrofolate Reductase (MTHFR) from Mediterranean to Sub-Saharan AreasRosa Chillemi, Andrea Angius, Ivana Persico et al.There are differences in the allele frequency of MTHFR polymorphism between Western and African population. The aim of this study is to determinate the prevalence of MTHFR C677T and A1298C polymorphisms in young and old people living in different areas from Mediterranean to sub-Saharan areas. The observed vs expected genotype frequencies of 677T were in Hardy Weinberg equilibrium, with the … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 7,590 accessesView PDFCite
