1. The biosynthesis of glucagon in guinea-pig A(2) cells was investigated by incubation of isolated islets of Langerhans in the presence of [(3)H]tryptophan for periods of up to 14 days. Proteins were extracted from islets and incubation media and analysed by gel filtration. 2. In addition to very-high-molecular-weight (100000) proteins, the principal tryptophan-containing biosynthetic product ...

The changes in photosynthetic activity, as well the activity of nitrogen-metabolism enzymes, intensity lipid peroxidation, and proline content were studied Triticum aestivum L. plants after their incubation at a low CO2 concentration sealed chamber for 10 d. deficiency (-CO2) compared to normal (control) led decrease rate O2 gas exchange plateau light cur...

Aligned porous non-sintered and sintered a-tricalcium phosphate (a-TCP) scaffolds are prepared by ice-templating converted into the low-temperature calcium phosphates calcium-deficient hydroxyapatite (CDHA), brushite monetite. This is achieved hydrothermal treatment or incubation in phosphoric acid solution has a high clinical potential due to higher solubility of these phases. Further details ...

in this paper, we present some inequalities for the co-pi index involving the some topological indices, the number of vertices and edges, and the maximum degree. after that, we give a result for trees. in addition, we give some inequalities for the largest eigenvalue of the co-pi matrix of g.

in this paper, we introduce the notion of primal strong co-ideals and give some results involving them. it is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. also we prove that the representation of strong co-ideals as reduced intersections of primal strong co-ideals is unique.

We present a novel highly efficient protocol to magnetically label T cells applying electrostatically stabilized very small superparamagnetic iron oxide particles (VSOP). Our long-term aim is to use magnetic resonance imaging (MRI) to investigate T cell dynamics in vivo during the course of neuroinflammatory disorders such as experimental autoimmune encephalomyelitis (EAE), an animal model of m...

Solid filtered or centrifuged potato processing wastes were obtained from three potato processors in Idaho. The waste samples were dried and ground to pass a 2-nun sieve and added to soils at rates of 0, 2.5, 10, and 25 g/kg. The 100-g samples of Portneuf silt loam soil containing the waste material was incubated at 26 °C and decomposition of the added wastes was determined by measuring CO, evo...

Proteins belonging to the B-subtype of the Hsp100/Clp chaperone family execute a crucial role in cellular thermotolerance. They cooperate with the Hsp70 chaperones in reactivation of thermally aggregated protein substrates. We investigated the initial events of the disaggregation reaction in real time using denatured, aggregated green fluorescent protein (GFP) as a substrate. Bacterial Hsp70 (D...
