The nonadiabatic photochemistry of the guanine molecule (2-amino-6-oxopurine) and some of its tautomers has been studied by means of the high-level theoretical ab initio quantum chemistry methods CASSCF and CASPT2. Accurate computations, based by the first time on minimum energy reaction paths, states minima, transition states, reaction barriers, and conical intersections on the potential energ...
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this re...
In the soft coral Sinularia leptoclados, 30 molecular species belonged to 4 glycerophospholipid classes, including 8 ethanolamine (PE), 13 choline (PC), 3 serine (PS) and 6 inositol (PI) were identified. PE 18:1e/20:4, PC 18:0e/20:4, PS 18:0e/24:5 PI 18:0/24:5 are most abundant with value of 69.94%, 45.57%, 68.55% 68.18%, respectively. The PE, PC, classes reported contain alkylacylphospholipid;...
Primary horse leukocyte cultures were inoculated with 2 or 10 50% tissue culture infective doses (TCID(50)) of equine infectious anemia (EIA) virus per cell, and the titer of cell-associated and fluid-phase virus was determined from 1 to 72 hr postinoculation (PI). Cover slips were collected from 4 to 72 hr PI and stained for EIA viral antigen by the indirect immunofluorescent (FA) technique. V...
Factors affecting the rate of glucose utilization by the intact mammalian erythrocyte have been the subject of several recent reports (l-3). The role of inorganic phosphate in the stimulation of erythrocyte glucose utilization (4) was examined by Rose, Warms, and O’Connell (2). The ability of Pi to moderate the effectiveness of glucose 6phosphate as an inhibitor of hexokinase was demonstrated b...
This paper presents a new 4-degree-of-freedom parallel mechanism dedicated to handling of heavy parts within a large workspace. These 4 degrees of freedom are 3 translations and 1 rotation about a given axis. Such a mechanism is rare; most of common parallel mechanisms have 3 or 6 degrees of freedom. Firstly, a description of the mechanism is given. Then models are derived regarding velocity an...
BACKGROUNDS/AIMS Pneumatosis intestinalis (PI) is a condition in which multiple gas-filled mural cysts develop in the gastrointestinal tract. Although its exact etiology remains obscure, PI is rarely observed in liver transplant (LT) recipients. METHODS In 317 cases of adult living donor LT (LDLT) performed during 2011, PI developed in three patients during the 3 year follow-up. RESULTS Of ...
Theoretical distribution of isoelectric points (pI values) of human blood proteins exhibits multimodality with a deep minimum in the range between pI 7.30 and 7.50. Considering that the pH of human blood is 7.4±0.1, normal forms of human proteins tend to eschew this specific pI region, thus avoiding charge neutrality that can result in enhanced precipitation. However, abnormal protein isoforms ...
Abstract Aim Organic substances in leaves of several southwest Australian native species interfere with sensitive colorimetric assays and prevent quantification inorganic phosphate concentration ([Pi]). We aimed to develop a reproducible routine procedure for treating leaf extracts activated charcoal (AC) remove interfering substances, allowing the determination [Pi] by malachite green spectrop...
