MgBr2 performs as a novel catalyst for the synthesis of various 1,5-benzodiazepine derivatives from wide range of substituted o- phenylenediamines and various ketones in good to excellent isolated yields （93-98%） using water as solvent at ambient temperature. Several solvents were examined for this reaction; however, in terms of reaction yield and time, water was found to be the optimum solvent. The remarkable advantages offered by this method are easily and inexpensive available catalyst, simple procedure, mild conditions, much faster （40-60 man） reactions and good to excellent yields of products.

We performed time resolved spectroscopy of 1H0707-495 and IRAS 13224-3809 using long XMM-Newton observations. These are strongly variable narrow line Seyfert 1 galaxies and show broad features around 1 keV that have been interpreted as relativistically broad Fe Lc~ lines. Such features are not clearly observed in other active galactic nuclei despite sometimes having high iron abundance required by the best fitted blurred reflection models. Given the importance of these lines, we explore whether the rapid variability of spectral parameters may introduce broad bumps/dips artificially in the time averaged spectrum, which may then be mistaken as broadened lines. We tested this hypothesis by performing time resolved spectroscopy using long （〉 100 ks） XMM-Newton observations and by dividing them into segments with typical exposures of a few ks. We extracted spectra from each such segment and modeled them using a two component phenomenological model consisting of a power law to represent the hard component and a black body to represent the soft emission. As expected, both the sources showed variations in the spectral parameters. Using these variation trends, we simulated model spectra for each segment and then co-added to get a combined simulated spectrum. In the simulated spectra, we found no broad features below 1 keV and in particular no deviation near 0.9 keV as seen in the real averaged spectra. This implies that the broad Fe Lα line that is seen in the spectra of these sources is not an artifact of the variation of spectral components and, hence, provides evidence that the line is indeed genuine.

Spine surgery is one of the fastest growing branches of orthopedic surgery. Patients often present with a relatively high acuity and, depending on surgical approach, morbidity and mortality can be comparatively high. Among the most prevalent and most frequently fatalitybound perioperative complications are those affecting the pulmonary system; evidence of clinical or subclinical lung injury triggered by spine surgical procedures is emerging. Increasing burden of comorbidity among the patient population further increases the likelihood of adverse outcome. This review is intended to give an overview over some of the most important causes of pulmonary complications after spine surgery, their pathophysiology and possible ways to reduce harm associated with those conditions. We discuss factors surrounding surgical trauma, timing of surgery, bone marrow and debris embolization, transfusion associated lung injury, and ventilator associated lung injury.
