OBJECTIVE To characterize national trends in non-fatal BB/pellet gun related injury rates for persons aged 19 years or younger in relation to trends in non-fatal and fatal firearm related injury rates and discuss these trends in light of injury prevention and violence prevention efforts. SETTING The National Electronic Injury Surveillance System (NEISS) includes approximately 100 hospitals wi...

The ablation interaction between a laser and solid samples, which affects the analytical performance for laser ablation inductively coupled plasma atomic emission spectrometry (LA-ICP-AES), was studied. The emission intensities of elements observed by LA-ICP-AES (LA-ICP-AES element signal intensities) for different solid samples were measured under different laser defocusing conditions with a f...

Depending on the growing industry and population, energy needs are increasing day by day. This issue makes it necessary use of renewable sources as much possible. There is a interest in pellet fuel pellet-fired combustion systems, which one sources. In this work, performance analyzes pellet-fueled boilers with two different feeding systems (horizontal-fed top-fed) flue gas outlet positions were...

abstract this investigation was conducted to replace artificial food with gammarus and study this effect on survival and growth parameters of jewel in case of completely randomized design with 3 treatments and 3 replicates in each treatments. 270 jewel fishes with initial mean weight of 1.22±0.72 were reared in 9 aquariums (30 fishes in each aquarium) with volume of 100 liter water. experimenta...

objective adult stem cells which are derived from different tissues, with their unique abilities to self-renew and differentiate into various phenotypes have the potential for cell therapy and tissue engineering. human adipose tissue is an appropriate source of mesenchymal stem cells with wide differentiation potential for tissue engineering research. in this study isolated stem cells from huma...

To determine the formation of ammonium from arginine by oral bacteria residing in saliva and dental plaque, an arginolytic activity assay based on the work described by Nascimento et al. [2] was developed. Following the original methodology, insufficient ammonium production could be determined. To improve the method for our research goal, the following modifications were made to the original pr...

PURPOSE To investigate the features of orbital injuries by pellets fired from the front. DESIGN Retrospective, 4 cases of pellet injuries. METHODS Five orbits of 4 patients who sustained pellet injuries received from the front were reviewed retrospectively. The course of injury and results were assessed. Radiological examinations were reviewed. The patients were evaluated between December 1...

Various examples of foreign body embolization of cerebral arteries, usually followed by serious consequences, have been reported (Lindberg et al., 1961; Chason et al., 1963; Steele et al., 1972; Wetli et al., 1972). However, a shotgun pellet entering the left atrium of the heart through a gunshot wound of the chest with subsequent embolic occlusion of one of the carotid arteries appears to be u...

Hormone replacement therapy by pellet implantation has been used with great success in the United States, Europe and Australia since 1938 and found to be superior to other methods of hormone delivery (Greenblatt 49, Mishnell 41, Cantrill 84, Stanczyk 88). It is not experimental. Pellets deliver consistent, physiologic levels of hormones and avoid the fluctuations of hormone levels seen with oth...
