Inorganic pyrophosphatase (PPase, EC 3.6.1.1) is an essential constitutive enzyme for energy metabolism and clearance of excess pyrophosphate. In this research, we investigated the sodium dodecyl sulfate (SDS)-induced inactivation and unfolding of PPase from Thermus thermophilus (T-PPase), a hyperthermophilic enzyme. The results indicated that like many other mesophilic enzymes, T-PPase could b...
Micellar-enhanced ultrafiltration (MEUF) of zinc ions (Zn2+) from aqueous solutions using single anionic surfactant sodium dodecyl sulphate (SDS) at low critical micelle concentrations (cmc) (0.2×cmc – 3×cmc) was investigated. When the initial SDS concentration was below the cmc, unexpectedly high rejection (97.5%) was obtained due to concentration polarisation occurring near the membrane-solut...
Sodium dodecyl sulphate (SDS) and sodium tripolyphosphate (STP) act to remove stained pellicle from dentition and loosen deposits on tooth surfaces that may become cariogenic over time. This study investigated how SDS and STP impact the salivary pellicle adsorbed onto hydroxyapatite and silica sensors using a dual polarisation interferometer and a quartz-crystal microbalance with dissipation. A...
Sequence Diagrams (SDs) have proven useful for describing transaction-oriented systems, and can form a basis for creating statecharts. However, distributed embedded systems require special support for branching, state information, and composing SDs. Actors must traverse many SDs when using a complex embedded system. Current techniques are insufficiently rich to represent the behavior of real sy...
The combination of SDS-PAGE and MS is one of the most powerful and perhaps most frequently used gel-based proteomics approaches in protein identification. However, one drawback of this method is that separation takes place under denaturing and reducing (R) conditions and as a consequence, all proteins with identical apparent molecular mass (Mr) will run together. Therefore, low-abundant protein...
There is little understanding of how anionic surfactants affect the transport carbon dots (CDs) nanoparticles in soil. In this study, mobility characteristics CDs soil columns with sodium dodecyl sulfate (SDS, a model surfactant) under various conditions were investigated. The results showed that presence SDS enhanced at pH 7.0 when Na + was main background electrolyte. increased electrostatic ...
The putative effects of diabetes and metabolic control on circulating levels of insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) remain controversial. In the present study, serum levels of IGF-I and IGF-II and IGFBP-1, -2, and -3 were measured in 58 patients (age, 0.8-17 yr) with treated (51 subjects) or untreated (7 subjects) insulin-dependent diabetes mellitus (IDDM) and...
AIMS OF THE STUDY (1) To assess psychological khat dependence and (2) to assess the validity and reliability of the Severity Dependence Scale (Gossop et al., 1995) amended for khat use (SDS-khat), in a sample of UK-resident male adult Yemeni khat chewers. MATERIALS AND METHODS A cross-sectional study using a face to face structured interview schedule was conducted amongst purposively sampled ...
The best way to protect yield loss of soybean [Glycine max (L.) Merr.] due to sudden death syndrome (SDS), caused by Fusarium virguliforme (Aoki, O'Donnel, Homma & Lattanzi), is the development and use of resistant lines. Mapping quantitative trait loci (QTL) linked to SDS help developing resistant soybean germplasm through molecular marker-assisted selection strategy. QTL for SDS presented her...
background: dicrocoelium dendriticum, a liver trematode of herbivores, and man is very prevalent among ruminants of iran, resulting in causing significant economic losses. recently its phenotype polymorphism has been found in iran, a phenomenon that may affect the protein profile of the parasite. objectives: the aim of this study was to determine the somatic protein profiles of d.dendriticum in...
