Mobilzation

Semiconductor quantum dots (QDs) are nanocrystals used in diverse optoelectronics. At the end of their useful life they are likely to end up in landfills, where they could be mobilzed by infiltrating rain water. In this work, spectroscopic and light scattering techniques were employed to investigate the environmental fate of QDs exposed to leachates from Austrian landfill sites containing municipal solid and bulky wastes. Brij-58-coated CdSe QDs, a model for surfactant stabilized hydrophobic nanoparticles, primarily sedimented before being degraded on a slower timescale in the course of 6 months...

BACKGROUND: Trauma-induced coagulopathy occurs in about 25% of injured patients and accounts for about 10% of deaths worldwide. Upon injury, hemostatic function may decline due to vascular dysfunction, clotting factor deficiencies, hyperfibrinolysis, and/or platelet dysfunction. We investigated agonist-induced calcium signaling in platelets obtained over time from trauma patients. METHODS: Platelets from trauma patients and healthy donors were monitored via intracellular calcium mobilization and flow cytometry markers (α2bβ3 activation, P-selectin display, and phosphatidylserine exposure) following stimulation with a panel of agonists (adenosine 5'-diphosphate sodium salt, U46619, convulxin, PAR-1/4 activating peptides, iloprost) used in isolation or in pairwise tests...

We have been treating patients with partial- and/or full-thickness burns of the hand using an easy and inexpensive technique called the glove-gauze method. Nine patients with 11 burned hands were treated with the glove-gauze regimen and monitored weekly for wound healing and range of motion. Excellent results were achieved in all patients who complied will full follow-up. This method is simple, accessible, safe, and extremely cost-effective and allows for immediate active mobilzization. We recommend use of the glove-gauze method for treating all burns of the hand that do not involve the underlying fascia, muscle, epitenon, paratenon, and/or bone...

Stem cell factor is an important hematopoietic growth factor. In this study, the human stem cell factor was produced by recombinant E. coli, and the structure and biological activity of the recombinant stem cell factor(rhSCF) was studied. It was indicated that the rhSCF was a uncovalent dimer in phosphate buffer,and had the correct mass spectra, mass peptides spectra, composition of amino acid, N-terminal sequernce, C-terminal sequence and intrachain disulfide linkages, rhSCF alone or synergy with rhG-CSF could mobilze hematopoietic progenitors to blood in monkey...

Mobilization of an intact omental pedicle graft for supportive use has been carried out in a variety of genitourinary reconstructive procedures. Mobilzation is accomplished by detachment of the omentum from the transverse colon and by separation from the greater curvature of the stomach. The right gastroepiploic artery is generally preserved as the blood supply to the omental pedicle. Further pedicle lengthening can be achieved as necessary by selective division of the omentum, based on the arterial anatomy...

Uroporphyrinogen decarboxylase was measured in the presence of ferrous iron, using mitochondria-free rat liver extracts as enzyme source. The activity of the enzyme was found to be increased at concentrations of ferrous iron from 0,01 mM, with maximal activity exhibited from 0,1 mM. Enzyme kinetics indicate that uroporphyrinogen decarboxylase reversibly binds ferrous iron, with a binding constant of approximately 5 x 10(4) mol-1. It is proposed that the effect of phlebotomy on patients with porphyria cutanea tarda is to mobilze storage iron in the liver to the active ferrous form, which activates hepatic uroporphyrinogen decarboxylase, the enzyme which is defective in this syndrome, with resultant clinical and biochemical remission...
