BACKGROUND Factors determining the shape of the human rib cage are not completely understood. We aimed to quantify the contribution of anthropometric and COPD-related changes to rib cage variability in adult cigarette smokers. METHODS Rib cage diameters and areas (calculated from the inner surface of the rib cage) in 816 smokers with or without COPD, were evaluated at three anatomical levels ...
the effect of expiratory rib – cage compression before endotracheal suctioning on blood pressure in patients under mechanical ventilation shrvani y [1] *, piami bosary m [2] , agha hasan kashani s3, mosavi nasab n4, ghafouri fard m5 received: 21 apr , 2013 accepted: 12 jul , 2013 abstract background & aims : in patients undergoing mechanical ventilation because of an endotracheal tub...
When repeatedly administered a dose of apomorphine (Apo), pigeons, much like rodents, show behavioural sensitization. In birds this sensitization expresses itself as an increasing pecking response to the drug and is found to be partially dependent on the environmental context in which Apo takes effect. In the first experiment we examined what effect different inter-Apo administration intervals ...
Efficiency of photoinitiators (PI) depends upon quantum yield of photogeneration of reactive free radicals and upon cage effect value. Only radicals that escape the cage can initiate free radical polymerization. The modern concept of the cage effect is presented. Dependencies of the cage effect upon increasing of solvent viscosity in the course of polymerization are discussed. Cage effect dynam...
helicobacter pylori has been strongly associated with peptic ulcer diseases, chronic gastritis, ulcers, and reported as a risk factor for gastric cancer, too. the vaculating cytotoxin (vaca), the cytotoxin associated genes (caga), the induced by contact with epithelium factor antigen (icea gene), blood adhesion binding antigen (baba2), and outer membrane protein oipa have been described as diff...
Background & Objective : The preferred Selection of the anterior cervical discectomy alone, with iliac crest bone graft fusion and using the PEEK cage is still in controversial in degenerative disc disease. The aim of this study is comparing them on radiographic and clinical results. Materials & Methods: The all consecutive patients in the three hospitals in Tehran between the 2000 up to the ...
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers. Table 1 Cage parameters used for the SLE analysis; viscosity (Z) in the cage, mutual diffusion coefficient (D) for the radical pair in the cage, escape probability (Pesc) at the interface, radius (R) of the cage, recombination reaction rate (krec) at the closest radical–radical di...
