AIM:To investigate the effect of hyaluronidase use on the quality of sub-Tenon's anaesthesia for phacoemulsification.· METHODS:This was a randomized,double-blind clinical trial which was conducted at Nikookari Eye Hospital for 5 ***-two eyes of candidates for phacoemulsification under sub-Tenon's anaesthesia were randomly allocated to two equal groups and received either 2 mL of lidocaine 2% solution with(LH),or without(L) addition of hyaluronidase(150IU/mL).Akinesia was assessed 15 minutes after sub-Tenon's *** and surgeon's satisfaction,as well as the postoperative pain(the visual analogue scale,VAS) were investigated after *** contingency tables(including the Chi-square or Fisher's exact tests,when appropriate) and parametric analysis(the independent samples t test) were used for statistical analysis.· RESULTS:Complete akinesia(33.3% vs 4.8%,P =0.04),as well as the patients(85.7% vs 57.1%,P =0.04)and surgeon's satisfaction(87.5% vs 52.4%,P =0.02) were significantly more frequent in LH than in L *** mean VAS was significantly lower in the same group(1.90±1.45 vs 3.00±1.55,P =0.04).· CONCLUSION:Addition of hyaluronidase to lidocaine solution for sub-Tenon's anesthesia significantly improves the ocular akinesia,enhances the intra-operative patients and surgeons' satisfaction,and attenuates the postoperative pain.·

Iran supports a great share of exotic and/or endemic plant genera and species. The genus Fritillaria(Liliaceae) is a precious part of this botanical richness with 19 species, of which 10 are endemic to the country. However, signs are mounting that the country is truly at a crossroads when it comes to preservation of this national wealth. In this regard, an effective conservation strategy should thoroughly consider the classification of Fritillaria, as conservation practices are compromised by knowledge gaps in systematics and taxonomy. As published studies on Fritillaria in Iran have been sporadic and limited in scope, the aim of this review is to provide information necessary to help bridge these information *** objective is to facilitate increased understanding of the geographic, taxonomic, cytogenetic and phylogenetic status of Iranian Fritilloria, which is vital to meeting the goal of sustainable conservation of the genus in Iran and neighboring areas.

Initially 324 articles were identified, and finally 22 studies were selected for review. Having reviewed the articles, the data needed were extracted and the results were synthesized ***: The results showed that most of the systems reviewed in this study used the minimum data set suggested by the World Health Organization injury surveillance guidelines along with supplementary data. The main functions considered for the system were injury track, data analysis, report, data linkage, electronic monitoring and data ***: ISISs can help to improve healthcare planning and injury prevention. Since different countries have various technical and organizational infrastructures, it is essential to identify system requirements in different settings.

6-12 nm silver nanoparticles were synthesized by the pulsed laser ablation of a high purity silver bulk in distilled water. Effect of laser fluence on the size, morphology and structure of produced nanoparticles has been studied experimentally. Pulses of a Q-switched Nd:YAG laser of 1064 wavelength at 7 ns pulse width at different fluences were employed to irradiate the silver target in water. The UV-Visible absorption spectra of the Ag nanoparticles exhibit surface plasmon resonance absorption peak in the UV region. TEM and SEM micrographs, in a good agreement with DLS results, indicate that with increasing the laser fluence the average size of spherical Ag nanoparticles is decreased. It is found that Ag nanoparticles exhibit photoluminescence emission with two peaks because of the inter band transition and electron-hole recombination.

Effect of laser fluence on the characteristics of gold nanoparticles (NPs) produced by laser ablation method is investigated experimentally. Five samples of gold NPs were synthesized by nanosecond pulsed laser ablation of a high purity gold plate in distilled water at five different fluences in the range of 1-3 J/cm2. Results show that in this experimental condition gold NPs are produced by nucleation of Au atoms in the plasma, generated on the target surface during the ablation process. There is threshold fluence at which absorption of laser energy by water rises significantly. Absorption of the laser energy by water leads to increase oxygen atoms in the ablation medium and formation of gold oxide NPs. By increasing the laser fluence below the threshold, size of produced NPs decreases while by increasing the laser fluence above the threshold size of produced NPs increases.
