pathologic fractures of the jaw are usually associated with aggressive, destructive lesions or malignant lesions of the jaws. aneurysmal bone cysts (abc) of the jaws are benign lesions which normally do not cause destruction to such an extent. this article reports a relatively aggressive abc of the mandible in a 19 year-old male which destroyed the buccal and lingual cortices as well as the inf...

in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

All-optical 4-bit Gray code to binary coded decimal (BCD) converter was demonstrated, for the first time in our knowledge, with the number of 12 SOAs by means of commercially available numerical analysis tool (VPI). Circuit design approach was modified appropriately in order to fit the electrical method on an all-optical logic circuit based on cross gain modulation (XGM) process so that signal ...

1. Measurements of visual purple regeneration in solution have been made by a procedure which minimized distortion of the results by other color changes so that density changes caused by the regenerating substance alone are obtained. 2. Bleaching a visual purple solution with blue and violet light causes a greater subsequent regeneration than does an equivalent bleaching with light which lacks ...

This summary covers the developments from 2006 in diesel regulations, engine combustion, and NOx and PM remediation. Regulatory developments are now focused on Europe, where light-duty Euro 5 and 6 regulations have been proposed for 2009 and 2014, respectively. The regulations are lass stringent than those in the US, but options exist for adopting European vehicles for the US market. Europe is ...

The rate of regeneration of reduced RNase by glutathione was examined in the presence of several added substances: substrate, phospholipid, other proteins, bacterial ribosomes, and neutral salts. Of these, only neutral salts showed substantial effects. K2HOP4 and (NH4)2SO4 strongly accelerated regeneration, the alkali chlorides showed moderate acceleration or inhibition, while LiBr and KSCN str...

The classical regenerative method of simulation output analysis exploits the regenerative structure of a stochastic process to break up a path into independent and identically distributed cycles based on a single sequence of regeneration times. If a process is regenerative with respect to more than one sequence of regeneration times, the classical regenerative method does not exploit the additi...

AIM The particular signals that start and orchestrate the regeneration process in pancreas are not well understood yet. We aimed to investigate the expression of nestin and chromogranin A in pancreatic regeneration zones and a secondary objective, we assessed the efficiency of pancreatic duct ligation method in creation of a pancreatic regeneration model in rats. MATERIALS AND METHODS Partial...

background: arterial damage is sometimes associated with supracondylar fractures of the humerus. diagnosis and careful management of the fracture and arterial repair is crucial. objectives: the aim of this study was to determine the prevalence and outcome of supracondylar fractures of the humerus with signs and symptoms of limb ischemia, before and after arterial decompression or arterial recon...
