Stromal cell-derived factor-1alpha (SDF-1alpha) mediated mobilization and homing of stem cells showed promising potential in stem cell based tissue engineering and regenerative medicine. However local and sustained release of SDF-1alpha is indispensable for stem cell mediated regenerative process due to its short half-life under inflammatory conditions. In this study, a gene activated collagen ...

We report here on the extension of Passive Flux Meter (PFM) applications for measuring fluxes of oxyanions in groundwater, and present results for laboratory and field studies. Granular activated carbon, with and without impregnated silver (GAC and SI-GAC, respectively), was modified with a cationic surfactant, hexadecyltrimethylammonium (HDTMA), to enhance the anion exchange capacity (AEC). La...

This study examines a water-based system, coupling an adsorber and a photoreactor, for regeneration of granular activated carbon (GAC) saturated with acetone and isopropyl alcohol (IPA). Through water recirculation the regeneration reaction was operated in both intermittent and continuous ultraviolet illumination modes. With a periodic dosage of hydrogen peroxide not only was regeneration effic...

The mitochondrial enzyme glutaminase C (GAC) catalyzes the hydrolysis of glutamine to glutamate plus ammonia, a key step in the metabolism of glutamine by cancer cells. Recently, we discovered a class of allosteric inhibitors of GAC that inhibit cancer cell growth without affecting their normal cellular counterparts, with the lead compound being the bromo-benzophenanthridinone 968. Here, we tak...

We announce a new construction of a stabilizing feedback law for nonlinear globally asymptotically controllable (GAC) systems. Given a control affine GAC system, our feedback renders the closed loop system input to state stable with respect to actuator errors and small observation noise. We also announce a variant of our result for fully nonlinear GAC systems.

an improved chemical regeneration of the granular activated carbon (gac) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (caf) was investigated. in the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed gac is 103% of original gac. using oxidant and surfact...

The carotenoids in Gac fruit (Momordica Cochinchinensis spreng) were analysed by high-performance liquid chromatography (HPLC), and the concentrations of beta-carotene, lycopene, zeaxanthin and beta-cryptoxanthin were measured. Lycopene was found to be predominantly present in the Gac seed membrane at a concentration of up to 380 microg/g of seed membrane. The concentration of lycopene in the G...

Oil and grease (O&G) removal efficiencies using 4 automobile stormwater treatment systems were investigated compared. The used were: low-cost granular activated carbon–rice husk (GAC–RH) filter system, river gravel–granular carbon (GR–GAC) rice only (RH) system the conventional PVC O&G trap (COT). Sampling of from five selected workshops was carried out manual grab sampling methods. inv...

The peel of Gac fruit (Momordica cochinchinensis Spreng.) contains high levels of bioactive compounds, especially carotenoids which possess significant antioxidant capacities. However, the peel of Gac is regarded as a waste from the production of carotenoid-rich oil from Gac fruit. In this study, carotenoids of Gac peel were extracted by microwave-assisted extraction (MAE) and ultrasound-assist...
