in this study, geometrical optimizations of clonidine drug were carried out with the hf/6-31g basissets .then, drug was put covalently to carbon nanocone with (5, 1) structure and a length of 150a. weuse chem office software and hyper chem at the end data will be presented as tables and figs.simulation was done in mm+, amber and opls force fields by monte carlo method. threeimportant energy par...

Aquaporins are integral membrane proteins from a larger family of major intrinsic proteins that formpores in the membrane of biological cells. Aquaporins form tetramers in the cell membrane with eachmonomer acting as a water channel.In this research, the AQP4 tetramer was modeled from its PDBstructure file, then, we have performed the intraction of aquaporin4 in different temperatures (298k,300...

Crystalline molecular machines represent an exciting new branch of crystal engineering and materials science with important implications to nanotechnology. Crystalline molecular machines are crystals built with molecules that are structurally programmed to respond collectively to mechanic, electric, magnetic, or photonic stimuli to fulfill specific functions. One of the main challenges in their...

OBJECTIVES To describe the population of aged as compared to young patients under mechanical ventilation and to analyze the mortality risk factors of this group in an intensive care unit. METHODS This was a prospective observational trial in patients over 18 years of age, admitted in an intensive care unit and under mechanical ventilation, during one year. Patients were divided into two group...

The photophysics of the 1-nitronaphthalene molecular system, after the absorption transition to the first singlet excited state, is theoretically studied for investigating the ultrafast multiplicity change to the triplet manifold. The consecutive transient absorption spectra experimentally observed in this molecular system are also studied. To identify the electronic states involved in the nonr...
