We have created the Knowledgebase of Standard Biological Parts (SBPkb) as a publically accessible Semantic Web resource for synthetic biology (sbolstandard.org). The SBPkb allows researchers to query and retrieve standard biological parts for research and use in synthetic biology. Its initial version includes all of the information about parts stored in the Registry of Standard Biological Parts...

A very simple, ultra-sensitive and highly selective non-extractive spectrophotometric method for the determination of trace amount of molybdenum(VI) using 5,7-dibromo-8-hydroxyquinoline (DBHQ) has been developed. 5,7-Dibromo-8-hydroxyquinoline reacts in a slightly acidic solution (0.05 - 1.0 M H2SO4) with molybdenum(VI) to give a deep greenish-yellow chelate which has an absorption maximum at 4...

Introduction: Early diagnosis of gastric cancer is the best solution for reversing cancer and curing patients. So far, gastric cancer is diagnosed in late stages due to misinterpretation of symptoms or absence of specific symptoms. Highly sensitive and selective detection methods for biomarkers are needed for early detection. Methods: This paper proposed a new fast screening method, based on t...

A PCR-based assay have been previously described to detect Wuchereria bancrofti in mosquitoes and in human blood samples. However, the efficiency of PCR amplification may vary between samples depending on the presence of PCR inhibitors, leading sometimes to false negative results. To overcome this drawback, an internal standard plasmid (pWB11) was constructed. It can be added to each PCR reacti...

The metabolome is an important class of molecules to study as it can lend insight into the health and well-being of an organism and the causative elements associated with disease. It integrates the effects of our genes with the impact of our environment by being the product of both internal factors (our genome and proteome) and external factors (our lifestyle and our environment). In addition, ...

The Laser Engineered Net Shaping (LENS) technique was combined with direct synthesis to fabricate L21-ordered Fe-Al-Ti based intermetallic alloys. It was found that ternary Fe-Al-Ti alloys can be synthesized using the LENS technique from a feedstock composed of a pre-alloyed Fe-Al powder and elemental Ti powder. The obtained average compositions of the ternary alloys after the laser deposition ...

An atomic absorption spectrometric method for the determination of trace amounts of zinc after adsorption of its [1-(2-pyridylazo)-2-naphthol] complex on microcrystalline naphthalene has been developed. This complex is adsorbed on microcrystalline naphthalene in the pH range 3.5-7.5 from large volumes of aqueous solutions of various alloys and biological samples with a preconcentration factor o...
