mAb CS-35 is representative of a large group of antibodies with similar binding specificities that were generated against the Mycobacterium leprae lipopolysaccharide, lipoarabinomannan (LAM), and which cross-reacted extensively with LAMs from Mycobacterium tuberculosis and other mycobacteria. That this antibody also cross-reacts with the arabinogalactan (AG) of the mycobacterial cell wall, sugg...
Plants utilize UDP-arabinofuranose (UDP-Araf) in the biosynthesis of Araf-containing complex carbohydrates. UDP-Araf is synthesized from UDP-arabinopyranose by UDP-arabinopyranose mutases (UAMs). Here we describe the heterologous expression of rice (Oryza sativa) UAM genes in insect cells and report some of their enzymatic properties. Recombinant UAMs might serve as useful tools for the biosynt...
Occurrence of azole-resistant Aspergillus fumigatus (ARAF) in the environment is an emerging problem worldwide, likely impacting on patient treatment. Several resistance mutations are thought to have initially arisen through triazole-based fungicide use in agriculture and subsequently being propagated in a similar manner. Here we investigated the prevalence of ARAF in the environment of Thailan...
Arabinofuranosyltransferase activity was identified in Golgi membranes obtained from mung bean (Vigna radiata) hypocotyls. The enzyme transfers the arabinofuranosyl (Araf) residue from UDP-beta-L-arabinofuranose to exogenous (1, 5)-linked alpha-L-arabino-oligosaccharides labeled at their reducing ends with 2-aminobenzamide. The transferred residue was shown, using 1H-nuclear magnetic resonance ...
Plant cell walls constitute the bulk of the earth renewable source of energy and are a component in the diet of humans and herbivores. l-Arabinofuranosyl (Araf) residues are a quantifiably important constituent of these walls. Plants use uridine diphosphate (UDP)-l-arabinofuranose (UDP-Araf) to donate Araf residues in the biosynthesis of Araf-containing polysaccharides, proteoglycans, and glyco...
This research aims to find out how the application of S}araf in reading yellow book using qualitative descriptive research. The subjects study were lecturers science s}araf, Qiraah and Mut}alaáh as well students Arabic program at IAIN Bone. Data collected through observation, interview documentation techniques. analysis was carried three stages continuously including data reduction, display con...
Targeted cancer therapies often induce "outlier" responses in molecularly defined patient subsets. One patient with advanced-stage lung adenocarcinoma, who was treated with oral sorafenib, demonstrated a near-complete clinical and radiographic remission for 5 years. Whole-genome sequencing and RNA sequencing of primary tumor and normal samples from this patient identified a somatic mutation, AR...
The structure and bioactivity of a polysaccharide extracted and purified from a 4M KOH + H3BO3 solution from Prunus dulcis seed cell wall material was studied. Anion-exchange chromatography of the crude extract yielded two sugar-rich fractions: one neutral (A), the other acidic (E). These fractions contain a very similar monosaccharide composition: 5:2:1 for arabinose, uronic acids and xylose, ...
UNLABELLED Histiocytic neoplasms are clonal, hematopoietic disorders characterized by an accumulation of abnormal, monocyte-derived dendritic cells or macrophages in Langerhans cell histiocytosis (LCH) and non-Langerhans cell histiocytosis (non-LCH), respectively. The discovery of BRAF(V600E) mutations in approximately 50% of these patients provided the first molecular therapeutic target in his...
Arabinose and galactose were treatedwithMeOH containing traces of H2SO4 or HCl at 25◦C to givemixtures of their methyl alphaand beta-furanosides, as shown by 1D and 2D nuclear magnetic resonance (NMR). Oxidation of the Me alpha,beta-Araf mixture with NaIO4 preferentially oxidised the beta-isomer, to give pure Me alpha-Araf . Each product was progressively O-methylated using the Purdie reagent (...
