Oxygen-carrying perfluorocarbon (PFC) fluids have the potential to increase tissue oxygenation during hypoxic states and to reduce ischemic cell death. Regulatory approval of oxygen therapeutics was halted due to concerns over vasoconstrictive side effects. The goal of this study was to assess the potential vasoactive properties of Perftoran by measuring brain pial arteriolar diameters in a hea...
A design diagram of comb formation roller in resilient stems is given. Comb-forming consists support and small discs, as well elastic rods. Elastic rods are installed along the perimeter diameter disks through their holes. Analytical dependences mathematical models obtained for determining distance between disks, diameter, length number One-factor experiments were carried out to substantiate It...
The present study was undertaken to investigate the role of banana extract (BE) on synchronous plantlet formation from seeds of Dendrobium lituiflorum Lindl. The seedlings formed on modified Knudson C (KC) medium supplemented with 20% (v/v) BE had significantly high fresh and dry weights. Morphologically uniform plantlets with elongated leaves and well developed roots were formed on KC medium w...
