ABSTRACT
Objective: To study the stinging flying Hymenoptera (Apidae and Vespidae) fauna in four Iranian Islands, Qeshm, Greater Tunb, Lesser Tunb and Abu-Musa on the Persian Gulf.Methods:hashing from March 2011 to July 2012. The flies were captured by used of Malaise trap, fly trap, bottle trap and insect net-Results: In this study, 11 species of stinging Hymenoptera were reported for the first time in Persian Gulf region.Conclusions:Some of this species such as Vespa orientalis and Polistes olivaceus are more common in the Persian Gulf islands and can cause clinical problem to islands resident and travelers.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the insecticidal effect of diatomaceous earth (DE) against adults and nymphs of Blattella germanica.</p><p><b>METHODS</b>This cross sectional study has been done on the laboratory strain of German cockroaches. Two stages, nymph and adult, were exposed to six dose rates of the DE, 2.5, 5, 10, 15, 20 and 25 g/m(2), at 24, 48 and 72 h exposure period. Mortality (number of dead cockroaches) was assessed after 24 h. Other exposed specimens were transferred to the beakers contained food and water for counting the retard mortality rate after 1 week.</p><p><b>RESULTS</b>Increasing in dose rates of DE increased mortality rate, so that the lowest and highest mortality rates were observed in 2.5 and 25 g/m(2), respectively. The results of the statistical analysis showed no significant difference in the lethality of 50% of DE plus water on the German cockroach nymphs.</p><p><b>CONCLUSIONS</b>Due to the resistance of German cockroach against organochloride, organophosphorus, carbamate and pyrethriodes insecticides, it is suggested to use DE for insect's control.</p>
ABSTRACT
Liver cirrhosis is associated with different types of electrophysiological changes, including QT prolongation, which may adversely affect long-term prognosis of these patients. The aim of this study is to evaluate the effect of orthotopic liver transplantation [LT] on corrected QT [QTc] interval and QT dispersion [QTd] in cirrhotic patients of various etiologies. We enrolled 249 patients with end-stage liver disease between 2004 and 2009 at Shiraz Transplant Research Center, Shiraz, Iran. The QTc interval and QTd were measured by 12 lead ECGs for baseline and at 3 months after LT. Mean QTc interval and mean QTd were calculated. A QTc interval above 440 ms was considered abnormal. Within 3 months following surgery, 6 patients died. There were 105 patients [43.2%] with prolonged QTc before transplantation; in 91 [86.6%] patients, the mean QTc normalized after transplantation [baseline: 490.9 +/- 45.74 ms; post-transplantation: 385 +/- 48.74 ms; P < 0.0001]. Fourteen patients [13.3%] had evidence of some shortening of the QTc interval although the QTc remained above the upper limit of normal. Prolongation of the QTc interval in cirrhotic patients was independent of the etiology of cirrhosis. A normal QTc was seen in 138 patients [56.7%] before transplantation, of which 4 [2.9%] developed prolonged QTc after transplantation. The mean QTd decreased significantly after transplantation [baseline: 30 +/- 20 ms; post-transplantation: 30 +/- 10 ms; P < 0.0001]. Many cirrhotic patients have prolonged QTc intervals before LT regardless of disease etiology. In the majority of patients this value returns to normal after LT, suggesting that liver cirrhosis has independent unfavorable, but reversible electrophysiological effects
