OBJECTIVES: This study sought to evaluate the safety and efficacy of endovascular treatment of middle cerebral artery dissecting aneurysms(MCADAs). METHOD: Fourteen patients with MCADAs received endovascular treatment between July 2009 and April 2016. MCADAs were identified by virtue of their unique radiographic features on cerebral angiography. Baseline characteristics, angiographic features, angiographic and clinical outcomes were analyzed retrospectively. RESULTS: All fourteen MCADAs (including 6 ruptured and 8 unruptured) were successfully treated with the endovascular approach...

Thirteen halophilic archaea were isolated from Kandla and Bhayander salt pans. These isolates were grouped into three different genera Halobacterium, Haloferax and Haloarcula based on morphological and biochemical characterization, polar lipid analysis, Amplified 16S rDNA restriction analysis (ARDRA) and 16S rDNA sequence analysis. Biochemical characterization suggested the ability of isolates to produce protease, amylase and poly-hydroxybutyrate (PHB) indicating their biotechnological potential. The isolates were further screened for the amount of extracellular protease produced...

Researchers have consistently advocated positive associations between religion and well-being. The present research takes a step forward and explores potential mechanisms behind the same. The mediating role of a surprisingly neglected mechanism, positive virtues, specifically gratitude, forgiveness and altruism, is studied through a quantitative study on a sample of 220 adult respondents residing in Delhi NCR. The participants adhered to one of the six major religions present in India. Mediational analysis revealed that gratitude mediated the relationship between religiosity, spirituality and well-being via two pathways of forgiveness and altruism...

THEORY: In the Project on the Good Physician, the authors propose a moral intuitionist model of virtuous caring that places the virtues of Mindfulness, Empathic Compassion, and Generosity at the heart of medical character education. HYPOTHESES: Hypothesis 1a: The virtues of Mindfulness, Empathic Compassion, and Generosity will be positively associated with one another (convergent validity). Hypothesis 1b: The virtues of Mindfulness and Empathic Compassion will explain variance in the action-related virtue of Generosity beyond that predicted by Big Five personality traits alone (discriminant validity)...

Magnetic skyrmion, a nano-sized spin texture with topological property, has become an area of significant interest due to the scientific insight that it can provide and also its potential impact on applications such as ultra low-energy and ultra high-density logic gates. In the quest for the reconfiguration of single logic device and the implementation of the complete logic functions, a novel reconfigurable skyrmion logic (RSL) is proposed and verified by micromagnetic simulations. Logic functions including AND, OR, NOT, NAND, NOR, XOR, and XNOR are implemented in the ferromagnetic (FM) nanotrack by virtue of various effects including spin orbit torque, skyrmion Hall effect, skyrmion-edge repulsions, and skyrmion-skyrmion collision...

Hypertension is one of the major causes of morbidity and mortality. Worldwide, Hypertension is estimated to cause 7.5 million deaths, about 12.8% of the total of all deaths. This accounts for 57 million disability adjusted life years (DALYS) or 3.7% of total DALYS. This led WHO to set a target of 25% reduction in prevalence by 2025. To reach that, WHO has adopted non-conventional methods for the management of hypertension? Despite worldwide popularity of such non-conventional therapies, only small volume of evidence exists that supports its effectiveness...

In this paper, we propose a method to construct invariant finite-difference schemes for solution of partial differential equations (PDEs) via consideration of modified forms of the underlying PDEs. The invariant schemes, which preserve Lie symmetries, are obtained based on the method of equivariant moving frames. While it is often difficult to construct invariant numerical schemes for PDEs due to complicated symmetry groups associated with cumbersome discrete variable transformations, we note that symmetries associated with more convenient transformations can often be obtained by appropriately modifying the original PDEs...

We study the effects of four-fermion interaction and impurity on the low-energy states of two-dimensional semi-Dirac materials by virtue of the unbiased renormalization group approach. The coupled flow equations that govern the energy-dependent evolutions of all correlated interaction parameters are derived after taking into account one-loop corrections from the interplay between four-fermion interaction and impurity. Whether and how four-fermion interaction and impurity influence the low-energy properties of two-dimensional semi-Dirac materials are discreetly explored and addressed attentively...

Adrenocortical carcinoma (ACC) is a rare malignancy associated with poor prognosis despite available treatments. In patients with localized or locally advanced disease, complete resection with negative margins offers the only potential for cure. Unfortunately, most patients develop local and distant recurrence following initial resection highlighting the importance of meticulous surgical technique in the hands of an experienced surgeon. While minimally invasive surgery (MIS) has supplanted open surgery for small to medium-sized benign adrenal tumors, controversy surrounds the use of MIS for resection of ACC...

Inorganic perovskite CsPbBr3 nanocrystals (NCs) are emerging, highly attractive light emitters with high color purity and good thermal stability for light-emitting diodes (LEDs). Their high photo/electroluminescence efficiencies are very important for fabricating efficient LEDs. Here, we propose a novel strategy to enhance the photo/electroluminescence efficiency of CsPbBr3 NCs through doping of heterovalent Ce3+ ions via a facile hot-injection method. The Ce3+ cation was chosen as the dopant for CsPbBr3 NCs by virtue of its similar ion radius and formation of higher energy level of conduction band with bromine in comparison with the Pb2+ cation to maintain the integrity of perovskite structure without introducing additional trap states...

The anticancer therapy on basis of reactive oxygen species (ROS)-mediated cellular apoptosis has achieved great progress. However, this kind of theraputic strategy still faces some challenges such as light, photosensitizer and oxygen (O2) dependence. In this article, a ROS-mediated anticancer therapy independent of light, photosensitizer and oxygen was established based on a Fe2+-induced ROS-generating nano-system. First, artemisinin (ART) was loaded in porous magnetic supraparticles (MSP) by a nano-deposition method...

Melittin (Mel), one of the host defense peptides (HDPs) derived from venom of honeybees, demonstrates substantial anticancer properties, which is considered attributed to augmenting reactive oxygen species (ROS) generation. However, little has been reported on its pro-oxidation capacity in cancer oxidation therapy. In this study, a ROS amplifying nanodevice was fabricated through direct complexation of two natural pro-oxidants, Mel and condensed epigallocatechin gallate (pEGCG). The obtained nanocomplex (NC) was further covered with phenylboronic acid derivatized hyaluronic acid (pHA) through ROS-responsive boronate ester coordination bond to produce pHA-NC...

The recent approval of edaravone by the United States Food and Drug Administration has generated a mix of hope tempered by reality. The costs of the drug, both monetarily and with regard to intensity of treatment, are high. The benefits, while modest, will be viewed through a very different lens by individuals depending on their goals of care. By virtue of our training and experience, physicians are ideally suited to understand and explain new treatments to our patients. As healthcare providers with a fiduciary responsibility to our patients, we must make sure they are fully informed about both the costs and benefits of non-curative therapies such as edaravone, and be prepared to discuss these in the context of their goals of care and potential impact on quality of life...

A green and sustainable approach for biorefining involves the development of bifunctional catalysts for the one-pot conversion of cellulosic biomass to isosorbide. This requires highly efficient, easily separated and versatile metal-acid catalysts for hydrolysis-hydrogenation-dehydration cascade reactions. Herein, we report a new type of metal-acid bifunctional catalyst by dispersing Ru nanoparticles (NPs) on magnetic yolk-shell nanoarchitectures comprising an Fe3O4 core and a sulfoacid (SO3H)-containing periodic mesoporous organosilica shell...

In this work, sulfur and nitrogen co-doped carbon dots (S,N-CQDs) as highly selective fluorescent probe for silver ion (Ag+) and cysteine (Cys) detection were designed and synthesized directly from citric acid and thiamine hydrochloride via a one-step hydrothermal protocol in 63.8% quantum yield. This probe enabled selective detection of Ag+ with a linear range of 0-10 and 10-250μM and a limit of detection of 0.40μM with respect to the variation in fluorescence induced by target concentration and electron-transfer from S,N-CQDs to Ag+...

The aim of the present work was to develop a rapid and interference-free method based on liquid chromatography-mass spectrometry (LC-MS) for the simultaneous determination of nine B-group vitamins in various energy drinks. A smart and green strategy that modeled the three-way data array of LC-MS with second-order calibration methods based on alternating trilinear decomposition (ATLD) and alternating penalty trilinear decomposition (APTLD) algorithms was developed. By virtue of "mathematical separation" and "second-order advantage", the proposed strategy successfully solved the co-eluted peaks and unknown interferents in LC-MS analysis with the elution time less than 4...

REVIEW
Umender Sharma, Aradhana Vipra, Shankaramurthy Channabasappa
Bacterial biofilms are highly resistant to the action of antibiotics. Presence of persisters, phenotypically resistant populations of bacterial cells, is thought to contribute toward recalcitrance of biofilms. The phage-derived lysins, by virtue of their ability to cleave the peptidoglycan of bacterial cells in an enzymatic manner, have the unique ability to kill dormant cells. Several lysins have shown potent antibiofilm activity in vitro. The fact that lysins have shown better efficacy than conventional drugs in animal models of endocarditis and other infections involving biofilms suggests that the lysins can potentially be developed against difficult-to-treat bacterial infections...

Recently, various fruitful organic reactions such as a catalytic Mitsunobu reaction were reported by virtue of alkyl 2-phenylazocarboxylates, however, the synthesis of alkyl 2-phenylazocarboxylates largely depended on the stoichiometric use of toxic oxidants. In this manuscript, an environment-friendly aerobic oxidative transformation of alkyl 2-phenylhydrazinecarboxylates to alkyl 2-phenylazocarboxylates was disclosed. The use of CuCl and DMAP system efficiently catalyzed the aerobic oxidation of alkyl 2-phenylhydrazinecarboxylates under mild conditions...

Emotional communication often needs the integration of affective prosodic and semantic components from speech and the speaker's facial expression. Affective prosody may have a special role by virtue of its dual-nature; pre-verbal on one side and accompanying semantic content on the other. This consideration led us to hypothesize that it could act transversely, encompassing a wide temporal window involving the processing of facial expressions and semantic content expressed by the speaker. This would allow powerful communication in contexts of potential urgency such as witnessing the speaker's physical pain...
