We are investigating membrane-based sorting processes in polarized epithelial MDCK cells, which most likely involves membrane microdomains. We have postulated that proteins contained in these microdomains, cluster, and to prove this, we have internalized differently fluorophore labeled pIgA-R ligands in MDCK cells, stably transfected with polymeric IgA receptors (pIgA-R), from opposite plasma m...
Beam Characterization of 10-MV Photon Beam from Medical Linear Accelerator without Flattening Filter
AIM This work investigated the dosimetric properties of a 10-MV photon beam emitted from a medical linear accelerator (linac) with no flattening filter (FF). The aim of this study is to analyze the radiation fluence and energy emitted from the flattening filter free (FFF) linac using Monte Carlo (MC) simulations. MATERIALS AND METHODS The FFF linac was created by removing the FF from a linac ...
A new analysis is presented of the recent photoionization spectrum of H2O, excited by double resonance via several rotational sublevels of the ~100! vibrational level of the C̃(B1) state. Evidence for a previously unsuspected strong f series indicates significant d orbital contamination of the nominal p orbital in the intermediate state. This is the first report of an f series in the Rydberg sta...
Di-Tert-Butyl-Peroxide Di-tert-butyl peroxide (DTBOO) a sufficiently stable molecule is a good candidate as precursor for the production and investigation of C4 – OO peroxy radicals. The most prominent absorption ( *-*) in DTBOO is in the UV spectral range between 340 nm and 230 nm. In order to learn more about the state manifolds connecting to the states of the fragments we started single phot...
High rates of both cyclic and noncyclic photophosphorylation were measured in chloroplast lamellae isolated from purified guard cell protoplasts from Vicia faba L. Typical rates of light-dependent incorporation of (32)P into ATP were 100 and 190 micromoles ATP per milligram chlorophyll per hour for noncyclic (water to ferricyanide) and cyclic (phenazine methosulfate) photophosphorylation, respe...
The use of epithermal neutron beam in clinical trials of Boron Neutron Capture Therapy for patients with malignant brain tumors had been carried out for half a decade at the Brookhaven's Medical Reactor. The decision to permanently close this reactor in 2000 cut short the efforts to implement a new conceptual design to optimize this beam in preparation for use with possible new BNCT protocols. ...
Laser produced plasma (LPP) sources for extreme ultraviolet (EUV) photons are currently based on using small liquid tin droplets as target that has advantages in generation of stable continuous targets at high repetition rate, larger photon collection angle, and reduced contamination and damage to optical mirror system from plasma debris and energetic particles. The ideal target is to generate ...
the aim of present study was to prepare gelatin nanoparticle for drug and gene delivery applications. these nanoparticles were prepared by two-step desolvation method. the body distribution of colloidal drug delivery systems was mainly influenced by two physicochemical properties namely particle size and surface characteristics. the influence of several factors on the fabrication process includ...
. We have searched for a heavy charged lepton with an associated neutrino of nearly the same mass in e+eannihilation data taken with the Mark II detector at a centerof-mass energy of 29 GeV. In order to suppress contamination from conventional two.photon reactions, this analysis uses a novel, radiative-tagging technique. Requiring . the presence of an isolated, energetic photon allows a search ...
