Published: May 2016

CaseA 74‐year‐old woman underwent computed tomography‐guided transthoracic needle biopsy of a small lung mass. Immediately after the procedure, she lost consciousness. After resuscitation, her brain computed tomography scan confirmed a cerebral air embolism.OutcomeAs hyperbaric oxygenation was unavailable, she received controlled normothermia for neuroprotection. No cerebral symptoms were observed following treatment.ConclusionAir embolisms are rare, but fatal, complications of computed tomography‐guided transthoracic needle biopsy. Therefore, clinicians should be familiar with early diagnosis and prompt treatment. Preventing hyperthermia might be effective for treating hypoxic brain injury caused by cerebral air embolisms.

AbstractRNA interference (RNAi) gene silencing technologies have shown significant potential for treating various diseases, including cancer. However, clinical success in cancer therapy remains elusive, mainly owing to suboptimal in vivo delivery of RNAi therapeutics such as small interference RNA (siRNA) to tumors. Herein, we developed a library of polymers that respond to a narrow pH change (ultra‐pH‐responsive), and demonstrated the utility of these materials in targeted and deep tumor‐penetrating nanoparticle (NP) for in vivo RNAi. The new NP platform is mainly composed of the following key components: i) internalizing RGD (iRGD) to enhance tumor targeting and tissue penetration; ii) polyethylene glycol (PEG) chains to prolong blood circulation; and iii) sharp pH‐responsive hydrophobic polymer to improve endosome escape. Through systematic studies of structure–function relationship, the optimized RNAi NPs (<70 nm) showed efficient gene silencing and significant inhibition of tumor growth with negligible toxicities in vivo.
Suppressing the P2–O2 Phase Transition of Na0.67Mn0.67Ni0.33O2 by Magnesium Substitution for Improved Sodium‐Ion Batteries

Published: May 2016

AbstractRoom‐temperature sodium‐ion batteries (SIBs) have shown great promise in grid‐scale energy storage, portable electronics, and electric vehicles because of the abundance of low‐cost sodium. Sodium‐based layered oxides with a P2‐type layered framework have been considered as one of the most promising cathode materials for SIBs. However, they suffer from the undesired P2–O2 phase transition, which leads to rapid capacity decay and limited reversible capacities. Herein, we show that this problem can be significantly mitigated by substituting some of the nickel ions with magnesium to obtain Na0.67Mn0.67Ni0.33−xMgxO2 (0≤x≤0.33). Both the reversible capacity and the capacity retention of the P2‐type cathode material were remarkably improved as the P2–O2 phase transition was thus suppressed during cycling. This strategy might also be applicable to the modulation of the physical and chemical properties of layered oxides and provides new insight into the rational design of high‐capacity and highly stable cathode materials for SIBs.

Abstract

Background
In randomized trials endovascular aortic aneurysm repair (EVAR) has been shown to have superior perioperative outcomes compared with open aneurysm repair (OAR). However, outcomes in patients at low risk of complications are unclear and many surgeons still prefer OAR in this cohort. The objective was to analyse perioperative and longer-term outcomes of OAR and EVAR in this low-risk group of patients.

Methods
All elective infrarenal EVARs and OARs in the Vascular Study Group of New England database were reviewed from 2003 to 2014. The Medicare scoring system was used to identity patients at low risk of perioperative complications and death. Perioperative and longer-term outcomes were analysed in this cohort. A Kaplan–Meier plot was constructed for evaluation of longer-term survival. Further propensity matching and multivariable analysis were performed to analyse additional differences between the two groups.

Results
Some 1070 patients who underwent EVAR and 476 who had OAR were identified. Mean(s.d.) age was 67·3(5·7) and 65·1(6·3) years respectively (P &lt; 0·001). EVAR was associated with a lower overall perioperative complication rate (4·2 versus 26·5 per cent; P &lt; 0·001). There was no difference in 30-day mortality (0·4 versus 0·6 per cent; P = 0·446). Overall survival at 3 years was similar after EVAR and OAR (92·5 versus 92·1 per cent respectively; P = 0·592). In multivariable analyses there was no difference in freedom from reintervention (odds ratio 1·69, 95 per cent c.i. 0·73 to 3·90; P = 0·220) or survival (hazard ratio 0·85, 0·61 to 1·20; P = 0·353).

Conclusion
In patients predicted to be at low risk of perioperative death following aneurysm repair, EVAR resulted in fewer perioperative complications than OAR. However, perioperative mortality, reinterventions and survival rates in the longer term appeared similar between endovascular and open repair.

AbstractActive sex steroids including estrogens and androgens are locally produced from circulating inactive steroids by various steroid‐metabolizing enzymes, and play pivotal roles in the progression of hormone‐dependent breast cancers. Human 3β‐hydroxysteroid dehydrogenase type 1 (3β‐HSD type 1) is a critical enzyme in the formation of all classes of active steroid hormones, and is also involved in the inactivation of potent androgen dihydrotestosterone (DHT). Therefore, this enzyme is suggested to modulate active sex steroid production or inactivation, with a role in hormone‐dependent breast cancer. The purpose of this study was to investigate the clinical significance of 3β‐HSD type 1 in human breast cancer. Using immunohistochemistry (IHC), we evaluated 3β‐HSD type 1 expression in 161 human breast cancers and analyzed correlations of 3β‐HSD type 1 expression with various clinicopathological factors. Of 161 breast cancer cases, 3β‐HSD type 1 expression in cancer cells was detected in 119 cases (73.9%), and was positively correlated with estrogen receptor (ER)‐positivity but not HER‐2 status. In ER‐positive cases (n = 130), 3β‐HSD type 1 expression was inversely correlated with invasive tumor size (P = 0.0009), presence of invasive region (P = 0.0107), and lymphatic involvement (P = 0.0004). 3β‐HSD type 1 expression was significantly associated with decreased risk of recurrence or improved prognosis by both univariate (P = 0.0003 and P = 0.009, respectively) and multivariate (P = 0.027 and P = 0.023, respectively) analyses. Our findings indicate that this enzyme is a prognostic factor in hormone‐dependent breast cancer.
Efficient view selection by measuring proxy information
Authors: Gao Tianhao , Wang Wencheng , Han Honglei 
Published: May 2016

AbstractView selection aims at finding good views that can watch model information as much as possible. However, existing view evaluation methods used to measure model properties are generally complex and very time‐consuming. In this paper, we address this challenge by generating succinct proxy information to measure the view quality. The proxy information is generated by principal component analysis of the model to obtain its six principal viewing directions and consists of the representative information computed by the principal viewing directions. We discuss and validate the effectiveness of the proxy information for view evaluation. Thus, measuring the proxy information for view evaluation, the time complexity can be reduced as it is independent of the facet number of the model. This is superior to existing methods by straight measurement of model properties and provides acceleration for view selection. Experimental results show that we can obtain good views as state‐of‐the‐art methods and speed up view selection by at least two orders of magnitudes and achieve more acceleration when the models have more facets.

Solvent‐Mediated Polymorphic Transformation of α‐Taltirelin by Seeded Crystallization
Authors: Nguyen Dang Le Tri , Kim Kwang‐Joo 
Published: May 2016

AbstractSolvent‐mediated polymorphic transformation (SMPT) of the α‐form into the β‐form of taltirelin (TTL) in seeded crystallization was investigated. The kinetics of polymorph transformation of the TTL was found to be a three‐dimensional growth of nuclei mechanism by the Avrami‐Erofeev equation. The transformation from the α‐form into the β‐form was also studied by crystallization adding α‐form seeds in solution. The effects of seed loading amount, temperature, supersaturation, and transformation time on polymorph transformation were evaluated. Seeded crystallization using α‐form crystals as a seed nucleated the α‐form TTL and then transformed the α‐form into the β‐form. The transformation rate was controlled by adjusting supersaturation.
Trends in Hydrogen Evolution Activity of Metal‐Modified Molybdenum Carbides in Alkaline and Acid Electrolytes

Published: May 2016

AbstractRelatively high surface area nanocrystalline molybdenum carbide (Mo2C) was modified with 5 wt % silver, copper, nickel, platinum, and palladium nanoparticles and subsequently assessed for its hydrogen evolution reaction (HER) activity in alkaline and acid electrolytes. Density functional theory (DFT)‐calculated hydrogen binding energies predicted that Pt–Mo2C and Pd–Mo2C should be most active, which was confirmed with experimental results. Similar activity trends were observed at both high and low pH values, with Cu–Mo2C being the least active. X‐ray photoelectron spectroscopy (XPS) confirmed that metal particles remained on the sample before and after HER testing. Pt‐modified nanocrystalline Mo2C showed superior HER activity compared with Pt‐modified commercial Mo2C, making it a potential replacement for bulk Pt in alkaline membrane electrolyzers. The positive effect on the HER activity of the metal contact with non‐passivated Mo2C surfaces was also demonstrated.
pH‐ and Thiol‐Responsive BODIPY‐Based Photosensitizers for Targeted Photodynamic Therapy

Published: May 2016

AbstractA diiodo distyryl boron dipyrromethene (BODIPY) core was conjugated to two ferrocenyl quenchers through acid‐labile ketal and/or thiol‐cleavable disulfide linkers, of which the fluorescence and photosensitizing properties were significantly quenched through a photoinduced electron‐transfer process. The two symmetrical analogues that contained either the ketal or disulfide linkers could only be activated by a single stimulus, whereas the unsymmetrical analogue was responsive to dual stimuli. Upon interaction with acid and/or dithiothreitol (DTT), these linkers were cleaved selectively. The separation of the BODIPY core and the ferrocenyl moieties restored the photoactivities of the former in phosphate buffered saline and inside the MCF‐7 breast cancer cells, rendering these compounds as potential activable photosensitizers for targeted photodynamic therapy. The dual activable analogue exhibited the greatest enhancement in intracellular fluorescence intensity in both an acidic environment (pH 5) and the presence of DTT (4 mm). Its photocytotoxicity against MCF‐7 cells also increased by about twofold upon preincubation with 4 mm of DTT. The activation of this compound was also demonstrated in nude mice bearing a HT29 human colorectal carcinoma. A significant increase in fluorescence intensity in the tumor was observed over 9 h after intratumoral injection.
