The use of metal oxides as anode materials in Li-ion batteries (LIBs) are of significant interest to many potential technologies, due to their high theoretical capacity, cost-effectiveness, and environmentally friendly features. In spite of these considerable benefits, and ongoing progress in the field, important challenges exist, associated with structural degradation due to volume expansion of electrode materials. This leads to rapid capacity fading, and must be resolved in order to move towards the practical use of high-performance LIBs with ultrafast cycling stability...

We report the hierarchical nano/micro architectured (HNMA)-polydimethylsiloxane (PDMS) film-based hybrid energy cells with multi-functionality to simultaneously harvest mechanical, solar, and wind energies. These films consist of nano/micro dual-scale architectures (i.e., nanonipples on inverted micro pyramidal arrays) on the PDMS surface. The HNMA-PDMS is replicable by a facile and cost-effective soft imprint lithography (SIL) using a nanoporous anodic alumina oxide (AAO) film formed on the micro-pyramidal (MP) structured silicon substrate...

Recent progress in the analysis of cell-free DNA fragments (cell-free circulating tumor DNA, ctDNA) now allows monitoring of tumor genomes by non-invasive means. However, previous studies with plasma DNA from patients with cancer demonstrated highly variable allele frequencies of ctDNA. Comprehensive genome-wide analysis of tumor genomes is greatly facilitated when plasma DNA has increased amounts of ctDNA. In order to develop a fast and cost-effective pre-screening method for the identification of plasma samples suitable for further extensive qualitative analysis, we adapted the recently described FAST-SeqS method...

Genomic characterization of cell-free circulating tumour DNA (ctDNA) may offer an opportunity to assess clonal dynamics throughout the course of a patient's illness. The existence of KRAS driver mutations in colon cancer patients is determinant to decide their treatment and to predict their outcome. DNA is extracted automatically from 400 μL of serum using the MagNa Pure Compact with the Nucleic Acid Isolation Kit I. DNA amplification, COLD-PCR and HRM were performed in the same run in the Light Cycler 480...

BACKGROUND: A recent systematic review suggested that drug registrations and onsite quality inspections may be effective in reducing the prevalence of counterfeit and substandard drugs. However, simply replicating the most effective interventions is problematic, as it denotes implementing the intervention without further adaptation. OBJECTIVE: The aim was to systematically review the evidence beyond effectiveness for systems-level interventions to combat or prevent drug counterfeiting...

Cetuximab is a novel biological agent with superior therapeutic efficacy for colorectal cancer treatment. This study aimed to systematically review the existing evidence related to the cost-effectiveness of cetuximab. Areas covered: Using Medline and Cochrane Database of Systematic Reviews, a total of 12 articles were identified. Previous studies have shown mixed results on the cost-effectiveness of first-line cetuximab combined with FOLFIRI (5-Fluorouracil, leucovorin, irinotecan). However, cetuximab-irinotecan therapy as third-line treatment has consistently been found to be cost-ineffective compared to best supportive care or no third-line therapy...

A whole-cell bioelectrochemical biosensing system for amperometric detection of riboflavin was developed. A "bioelectrochemical wire" (BW) consists of riboflavin and cytochrome C between S. oneidensis MR-1 and electrode was characterized. Typically, strong electrochemical response was observed when riboflavin was added to reinforce this BW. Impressively, the electrochemical response of riboflavin with this BW was over 200 times higher than that without bacteria. Uniquely, this electron rewiring process enabled the development of a biosensing system for amperometric detection of riboflavin...

The main barriers to cost-effective lactic acid production from lignocellulose are the high cost of enzymes and the ineffective utilization of the xylose within the hydrolysate. In the present study, the thermophilic Bacillus coagulans strain CC17 was used for the simultaneous saccharification and fermentation (SSF) of bagasse sulfite pulp (BSP) to produce l-lactic acid. Unexpectedly, SSF by CC17 required approximately 33.33% less fungal cellulase than did separate hydrolysis and fermentation (SHF). More interestingly, CC17 can co-ferment cellobiose and xylose without any exogenous β-glucosidase in SSF...
