We recently developed a mathematical model for predicting reactive oxygen species (ROS) concentration and macromolecules oxidation in vivo. We constructed such a model using Escherichia coli as a model organism and a set of ordinary differential equations. In order to evaluate the major defences relative roles against hydrogen peroxide (H2 O2), we investigated the relative contributions of the ...

this study was undertaken to identify key elements for obtaining community interest and motivate them to support eliminate malaria in the places that malaria is no longer a perceived threat.sequential explanatory mixed methods research design used to provide more comprehensive evidence research. a questionnaire was developed after reviewing the literature relating to community participation for...

BACKGROUND We have treated 4 patients of acute erythematous skin diseases with fever and/or pain by H2 enriched intravenous fluid. We also added data from two volunteers for assessing the mode of H2 delivery to the skin for evaluation of feasibility of H2 treatment for this type of skin diseases. METHODS All of the four patients received intravenous administration of 500 ml of H2 enriched flu...

Very recently, we proposed an automated method for finding transition states of chemical reactions using dynamics simulations; the method has been termed Transition State Search using Chemical Dynamics Simulations (TSSCDS) (E. Martínez-Núñez, J. Comput. Chem., 2015, 36, 222-234). In the present work, an improved automated search procedure is developed, which consists of iteratively running diff...

Quantum scattering calculations of vibration-vibration (VV) and vibration-translation (VT) energy transfer for non-reactive H2-H2 collisions on a full-dimensional potential energy surface are reported for energies ranging from the ultracold to the thermal regime. The efficiency of VV and VT transfer is known to strongly correlate with the energy gap between the initial and final states. In H2(v...

BACKGROUND We have previously shown that hydrogen (H2) inhalation, begun at the start of hyperoxic cardiopulmonary resuscitation, significantly improves brain and cardiac function in a rat model of cardiac arrest. Here, we examine the effectiveness of this therapeutic approach when H2 inhalation is begun on the return of spontaneous circulation (ROSC) under normoxic conditions, either alone or ...

Fourier transform absorption spectra of H2 O-enriched and H2 O-enriched water vapor in the 3m + d and 4m polyad region have been analyzed. With the aid of theoretically calculated linelists, we have assigned 1014 lines attributed to H2 O and 836 lines of 855 attributed to H2 O. Seven new band origins are found for H2 O and one for H2 O. 2005 Elsevier Inc. All rights reserved.

Soil microbial communities are continuously exposed to H2 diffusing into the soil from the atmosphere. N2-fixing nodules represent a peculiar microniche in soil where H2 can reach concentrations up to 20,000 fold higher than in the global atmosphere (0.530 ppmv). In this study, we investigated the impact of H2 exposure on soil bacterial community structure using dynamic microcosm chambers simul...

Substituted bis(iminophosphoranyl)methanes are CH acidic compounds that can form 15 complexes with formally dianionic central carbon centres. The reaction of H2C(Ph2P=NDip)2 (≡ 16 H2L), Dip = 2,6-diisopropylphenyl, with one equivalent of di-n-butylmagnesium afforded the 17 methanide complex [HLMgnBu] 1. Treatment of complex 1 with phenylsilane in aromatic solvents 18 at elevated temperatures af...
