A catalyst based on immobilization of a molybdenum(VI) Schiff base complex on γ-Fe2O3 magnetic nanoparticles has been synthesized and characterized. This catalyst was employed for the selective oxidation of alcohols to the corresponding carbonyl compounds in EtOH/H2O2. The catalyst can be easily separated from the reaction mixture by decantation using an external magnet and reused efficiently in five subsequent reaction cycles without any significant decrease in activity or selectivity. © 2016 Springer International Publishing Switzerland Source

Purpose: The purpose of this study was to assess the results of bleb needling in glaucomatous patients with late failed filtering blebs. Materials and Methods: A retrospective case series of 27 eyes of 27 patients was considered. All patients underwent needle bleb revision with adjuvant mitomycin-C performed at the slit lamp, during an office visit. Complete success was defined as postneedling intraocular pressure (IOP) ≤21 mmHg without any antiglaucoma medications and qualified success was IOP ≤21 mmHg with topical antiglaucoma medications. Results: There were 12 eyes with encapsulated blebs and 15 eyes with flat blebs. The mean interval between index filtering surgery and bleb revision was 32.74 ± 15.36 months. Mean IOP was 25.07 ± 4.80 mmHg before surgery and 19.66 ± 4.97 mmHg at last postoperative follow-up. The mean follow-up was 20.31 ± 15.63 months. Complete and qualified successes were 7.4% and 51.9%, respectively. Cumulative rates of success at 1, 2, 3, and 4 years were 76%, 65%, 49%, and 37%, respectively. The mean number of antiglaucoma medications was reduced from 3.15 ± 0.36 preoperatively to 2.33 ± 1.21 postoperatively (P<0.001). Conclusion: Slit-lamp needle revision in office is a simple and effective method for treating late encapsulated or flat filtering blebs without significant complications even for late bleb failure.

Aim: To evaluate changes of nasal and temporal anterior chamber angle (ACA) in subjects with angle closure glaucoma using Spectralis AS-OCT (SAS-OCT) under dark and light conditions. Methods: Based on dark-room gonioscopy, 24 subjects with open angles and 86 with narrow angles participated in this study. The nasal and temporal angle opening distance at 500. μm anterior to the scleral spur (AOD500), nasal and temporal ACA were measured using SAS-OCT in light and dark conditions. Result: In 2 groups, ACA and AOD500 in nasal and temporal quadrants were significantly greater in light compared to dark (all with p= 0.000). The AOD500 and ACA were significantly higher in nasal than temporal in measured conditions for 2 groups except the ACA and AOD500 of normal group measured in light. The difference between nasal and temporal in dark (29.07. ±. 65.71. μm for AOD500 and 5.7. ±. 4.07° for ACA) was greater than light (24.86. ±. 79.85. μm for AOD500 and 2.09. ±. 7.21° for ACA) condition. But the difference was only significant for ACA ( p= 0.000). The correlation analysis showed a negative correlation between AOD500 and pupil diameter in temporal and nasal quadrants (both with p= 0.000). While temporal AOD500 difference correlated with spherical equivalent, temporal and asal gonioscopy, nasal AOD correlated with IOP, temporal and nasal gonioscopy. Conclusions: Clinically important changes in ACA structure could be detected with SAS-OCT in nasal and temporal quadrants under different illumination intensity. The results could help in improvement of examination condition for better and more accurate assessment of individuals with angle closure glaucoma. © 2014 British Contact Lens Association. Source

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'Can intracoronary stem cell injection permanently improve cardiac function after myocardial infarction?'. Altogether 314 papers were found using the reported search, of which five represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that stem cells may have controversial effects on cardiac function in long-term follow-up of more than two years as they improved the left ventricular ejection fraction and end systolic volume index just in two studies in which none of them utilized cardiac magnetic resonance imaging (MRI), as the most reliable method, to quantify cardiac function. However, all remaining three trials which reported negative results used cardiac MRI for assessment of cardiac indexes which may be more precise and accurate than echocardiographic assessments. So the reliability of the positive trials is lower than negative resulted trials in terms of cardiac function assessment method. Stem cell therapy almost always offered short-term benefits over the best medical treatment, but the long-term benefits are still a matter of debate. © 2011 Published by European Association for Cardio-Thoracic Surgery.

Background: One of the most common problems faced in laparoscopic treatment of hydatid cysts is the difficulty in evacuating the particulate contents (daughter cysts and laminated membrane). Although various instruments and laparoscopic techniques have been described to evacuate the contents of hydatid cysts, most are not available at many surgical centers. Methods: By assembling disposable, cheap, and available anesthesia equipment with common laparoscopic instruments, a laparoscopic system was made to evacuate the contents of a hydatid cyst. Ten patients with hepatic hydatid disease underwent laparoscopic surgery using this new hydatid system between June 2011 and January 2013. Results: The procedure was completely straightforward. Twelve hydatid cysts (2 patients had 2 separated cysts) were evacuated without any spillage. All patients were followed for at least 8 months, with no evidence of recurrence. Conclusions: This simple apparatus, which can be assembled anywhere, was safely used to evacuate the contents of hydatid cysts without causing any spillage. © 2014 by JSLS, Journal of the Society of Laparoendoscopic Surgeons.
