Development of efficient, affordable, and sustainable energy storage technologies has become an area of interest due to the worsening environmental issues and rising technological dependence on Li-ion batteries. Na-ion batteries (NIBs) have been receiving intensive research efforts during the last few years. Owing to their potentially low cost and relatively high energy density, NIBs are promising energy storage devices, especially for stationary applications. A fundamental understanding of electrode properties during electrochemical reactions is important for the development of low cost, high-energy density, and long shelf life NIBs...

Reducing costs and increasing benefits for rural communities coexisting with large carnivores is necessary for conservation of jaguar (Panthera onca) and puma (Puma concolor). To design acceptable incentives, stakeholders must be involved in the process. We conducted an innovative structured group communication process, based on a Delphi technique, as a template for identifying potential incentives. Community workshops with 133 members of 7 communities and iterative surveys with 25 multidisciplinary experts from government, NGOs and academia provided iterative data to design a plan of incentives through 4 rounds of discussion...

Silicon is a material with very good thermoelectric properties, with regard to Seebeck coefficient and electrical conductivity. Low thermal conductivities, and hence high thermal to electrical conversion efficiencies, can be achieved in nanostructures which are smaller than the phonon mean free path but large enough to preserve the electrical conductivity. We demonstrate that it is possible to fabricate a leg of a thermoelectric generator based on large collections of long nanowires, placed perpendicularly to the two faces of a silicon wafer...

Yue Zhao, Yousheng Mao
Esophageal cancer is one of the most common malignant digestive system cancers in China, which has high incidence and mortality. Nowadays, surgery remains the most important part of the comprehensive treatments. Conventional open esophagectomies are highly traumatic with high morbidity, while minimally invasive esophagectomy has been increasingly used with the development of surgical instruments and techniques in recent years. Compared with conventional open esophagectomy(OE), what are the advantages of minimally invasive esophagectomy (MIE) and which is preferable? This review briefly introduces the developing history of MIE and common procedures...

Uptake of preexposure prophylaxis (PrEP) has been slow, but is increasing. Although PrEP is indicated for many patients, it has been concentrated among men who have sex with men (MSM). Awareness of PrEP is limited among non-MSM individuals, and among some MSM. As such, individuals at risk for HIV who are unaware of PrEP must rely on their medical providers to initiate conversations about PrEP. Members of a national professional organization of HIV specialists with prescribing privileges, including physicians, nurse practitioners, and physician assistants, participated in an online survey ( n = 342) to characterize their PrEP prescribing behaviors and the demographic membership of their PrEP patients...

INTRODUCTION: Acromioclavicular joint injuries are common shoulder girdle injuries most commonly resulting from a direct blow to the acromion with the arm adducted. Type-I or type-II acromioclavicular joint injuries can be managed with sling immobilization, early shoulder motion, and physiotherapy. The management of type-III injuries remains controversial and is individualized. Type IV and V injuries should be treated surgically. A myriad of surgical techniques for the management of acromioclavicular joint injuries have been reported...

Studying how and where drugs are metabolized in the brain is challenging. In an entire organism, peripheral metabolism produces many of the same metabolites as those in the brain, and many of these metabolites can cross the blood-brain barrier from the periphery, thus making the relative contributions of hepatic and brain metabolism difficult to study in vivo. In addition, drugs and metabolites contained in ventricles and in the residual blood of capillaries in the brain may overestimate drugs' and metabolites' concentrations in the brain...

Motivation: It is highly desirable to assemble genomes of high continuity and consistency at low cost. The current bottleneck of draft genome continuity using the Second Generation Sequencing (SGS) reads is primarily caused by uncertainty among repetitive sequences. Even though the Single-Molecule Real-Time sequencing technology is very promising to overcome the uncertainty issue, its relatively high cost and error rate add burden on budget or computation. Many long-read assemblers take the overlap-layout-consensus (OLC) paradigm, which is less sensitive to sequencing errors, heterozygosity and variability of coverage...

BACKGROUND: The subcellular localization of a protein is an important aspect of its function. However, the experimental annotation of locations is not even complete for well-studied model organisms. Text mining might aid database curators to add experimental annotations from the scientific literature. Existing extraction methods have difficulties to distinguish relationships between proteins and cellular locations co-mentioned in the same sentence. RESULTS: LocText was created as a new method to extract protein locations from abstracts and full texts...

OBJECTIVE: Current antiepileptic drugs (AEDs) have several shortcomings. For example, they fail to control seizures in 30% of patients. Hence, there is a need to identify new AEDs. Drug repurposing is the discovery of new indications for approved drugs. This drug "recycling" offers the potential of significant savings in the time and cost of drug development. Many drugs licensed for other indications exhibit antiepileptic efficacy in animal models. Our aim was to create a database of "prescribable" drugs, approved for other conditions, with published evidence of efficacy in animal models of epilepsy, and to collate data that would assist in choosing the most promising candidates for drug repurposing...

BACKGROUND: Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. METHODS: All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset...

Background: Low pollen viability may limit grapevine yield under certain conditions, causing relevant economic losses to grape-growers. It is usually evaluated by the quantification of the number of viable and non-viable pollen grains that are present in a sample after an adequate pollen grain staining procedure. Although the manual counting of both types of grains is the simplest and most sensitive approach, it is a laborious and time-demanding process. In this regard, novel image-based approaches can assist in the objective, accurate and cost-effective phenotyping of this trait...

A new one-pot cascade reaction-based application of Povarov reactions (MCPRs) with a p-sulfonic acid calix[4]arene (CX4SO3H) catalyst for the synthesis of a series of 34 julolidines derivatives with substituents at C8 or C9 in good to excel-lent yields is reported. These microwave-assisted reactions proceed efficiently, had short reaction times, were metal-free, were low cost, and used an inexpensive, easily available and nontoxic catalyst. These advantages, along with a simple work-up procedure, make this protocol a very efficient and green alternative to the traditional methods for constructing these types of N-heterocyclic skeletons...

MicroRNAs (miRNAs) are single stranded endogenous molecules composed of only 18-24 nucleotides which are critical for gene expression regulating the translation of messenger RNAs. Conventional methods based on enzyme-assisted nucleic acid amplification techniques have many problems, such as easy contamination, high cost, susceptibility to false amplification, and tendency to have sequence mismatches.Here we report a rapid, ratiometric, enzyme-free, sensitive, and highly selective single-step miRNA detection using three-way junction assembled (or self-assembled) FRET probes...

The surface-assisted laser desorption/ionization (SALDI) effect is investigated on Au plated anodized aluminum oxide (Au/AAO) thin films, a new type of low-cost broadband plasmonic absorber, which has attracted a lot of attention recently. Mass spectrometry (MS) measurements show that the ionization efficiency of Au/AAO substrates can be significantly improved (×30 fold) by simply tuning the size of nanopores in Au/AAOs. This leads to a signal-to-noise ratio of 394, which is 4 times better than the result obtained using the conventional matrix-assisted laser desorption/ionization (MALDI)-MS technique...

As robotics are becoming more integrated into the medical field, robotic training is becoming more crucial in order to overcome the lack of experienced robotic surgeons. However, there are several obstacles facing the development of robotic training programs like the high cost of training and the increased operative time during the initial period of the learning curve, which, in turn increase the operative cost. Robotic-assisted laparoscopic prostatectomy is the most commonly performed robotic surgery. Moreover, robotic surgery is becoming more popular among urologic oncologists and pediatric urologists...
