From graphene oxide wrapped iron oxide particles with etching/reduction process, high-performance anode and cathode materials of lithium-ion hybrid supercapacitors are obtained in the same process with different etching conditions, which consist of partially etched crumpled graphene (CG) wrapped spiky iron oxide particles (CG@SF) for a battery-type anode, and fully etched CG for a capacitive-type cathode. The CG is formed along the shape of spikily etched particles, resulting in high specific surface area and electrical conductivity, thus the CG-based cathode exhibits remarkable capacitive performance of 210 F g-1 and excellent rate capabilities...

In a compelling study, Hicks Pries et al (Reports, 31 March 2017, p. 1420) showed that 4°C warming enhanced soil CO2 production in the 1-meter soil profile, with all soil depths displaying similar temperature sensitivity (Q10 ). We argue that some caveats can be identified in their experimental approach and analysis, and that these critically undermine their conclusions and hence their claim that the strength of feedback between the whole-soil carbon and climate has been underestimated in terrestrial models...

Multiple births or twinning in cattle is a naturally occurring reproductive phenomenon. For dairy cattle, twinning is considered a detrimental trait as it can be harmful to cow and calf as well as costly to the producer. The objective of this study was to examine recent US calving records for the Holstein breed to determine a current estimate of heritability for twinning rate along with effects of season and parity. Two models were used in this study: a linear sire model and a binary threshold-logit sire model...

PURPOSE: Nivolumab has been administered using a 60-min infusion time. Reducing this time to 30 min would benefit both patients and infusion facilities. This analysis compared the safety of 30- and 60-min infusions of nivolumab in patients with previously treated advanced non-small cell lung cancer. METHODS: CheckMate 153 is an open-label, phase 3b/4, predominantly community-based study ongoing in the United States and Canada. Patients with stage IIIB/IV disease with progression/recurrence after at least one prior systemic therapy received nivolumab 3 mg/kg every 2 weeks over 30 or 60 min for 1 year or until disease progression...

As a common antagonist of Wnt/β-catenin signaling, Wnt inhibitory factor 1 (WIF1) plays an important role in the tumor progression. The aim of our meta-analysis was to summarize the diagnostic value of WIF1 methylation in colorectal cancer (CRC). Eligible studies were retrieved by a systemic search among PubMed, Embase, CNKI, and Wanfang literature databases. The diagnostic value of WIF1 methylation for CRC was assessed by the summary receiver operating characteristics (SROC) test. Our meta-analysis of 12 studies between 1420 CRC samples and 946 control samples showed that WIF1 hypermethylation was significantly associated with CRC (P < 0...

Rbpms (RNA-binding protein with multiple splicing) is a member of the RRM (RNA Recognition Motif) family of RNA-binding proteins, which is expressed as multiple alternatively spliced transcripts encoding different protein isoforms. We have shown earlier that Rbpms expression in the retina is restricted to retinal ganglion cells (RGCs), and have characterized this gene as a marker for RGCs. The aim of this study was to identify isoforms representing Rbpms in human retinas and to analyze its transcriptional regulation...

The recently described Lyme disease spirochete Borrelia mayonii is associated with human illness in the Upper Midwest of the United States. Experimental laboratory studies and field observations on natural infection indicate that B. mayonii is maintained by horizontal transmission between tick vectors and vertebrate reservoirs. While maintaining a colony of Ixodes scapularis Say (Acari: Ixodidae) ticks infected with the B. mayonii type strain (MN14-1420), we had an opportunity to examine whether infected females may pass this spirochete transovarially to their offspring...

The past decades have seen significant interest in the study of polyphenolic compounds as potential therapeutic agents in medicine because they display a vast array of cellular effects beneficial to treat or manage a plethora of chronic diseases including inflammatory diseases, cardiovascular abnormalities and several types of cancer. These compounds act at different stages of carcinogenesis but deciphering their mode of action is a complex task. Live MCF-7 breast cancer cells were investigated using Raman imaging to evaluate the perturbations induced after incubating cells with four different polyphenols: EGCG, gallic acid, resveratrol and tannic acid...
