immature teeth have a large apical opening and thin divergent or parallel dentinal walls; hence, with conventional needle irrigation there is a very high possibility of extrusion. this study was done to compare the apical extrusion of naocl in an immature root delivered using endovac and needle irrigation.eighty freshly extracted maxillary central incisors were decoronated followed by access ca...

to evaluate the quality of services in hospitals can rely on mortality rate and side effects rate. according to performed studies, side effects rate is a better indicator to evaluate the quality of hospital services, therefore decreasing of side effects is one of the main objectives in hospital management. a side effect of open-heart surgery is the skin damage. some of iranian patients who were...

a necessary and sufficient condition in terms of lower cut sets are given for the insertion of a $gamma-$continuous function between two comparable real-valued functions.

open-celled foams are capable to allow the passage of fluids through their structure, because of interconnections between the open cells or bubbles and therefore these structures can be used as a membrane and filter. in thiswork, we have studied the production of polystyrene open-celled microcellular foam by using co2 as blowing agent. to achieve such structures, it is necessary to control the ...

appendicitis is the most common surgical emergency with the incidence rate of 6-10%. although several studies have compared the two approaches of open (oa) and laparoscopic appendectomy (la) the technique of choice is still a matter of controversy. considering this background we designed a study to compare oa and la outcomes in our center. one hundred patients were included in this study perfor...

background: splenic cysts are known as rare clinical encounter. classifying into primary (true) and secondary cysts (pseudocysts), true cysts contain cellular epithelial lining and subdivided into parasitic and non-parasitic cysts. this study aimed to determine the outcome of treatment in patients with splenic cyst. methods: all patients with splenic cyst who had been treated in department of g...

The development of compartments in eukaryotic cells and the distribution of nuclear-encoded proteins underlies the expansion of plant genomes, the proliferation of multigene families and the specialization of cellular functions. The exploration of the proteome of the cell in terms of the collection of its subcompartments is therefore both a practical approach and also a function led necessity t...
