In order to reduce the amount of inactive materials, such as binders and carbon additives in battery electrode, porous cobalt monoxide nanofibers were directly grown on conductive substrate as a binder/additive-free lithium-ion battery anode. This electrode exhibited very high specific discharging/charging capacities at various rates and good cycling stability. It was promising as high capacity anode materials for lithium-ion battery.

Different types of sequencing biases have been described and subsequently improved for a variety of sequencing systems, mostly focusing on the widely used Illumina systems. Similar studies are missing for the SOLiD 5500xl system, a sequencer which produced many data sets available to researchers today. Describing and understanding the bias is important to accurately interpret and integrate these published data in various ongoing research projects. We report a particularly strong GC bias for this sequencing system when analyzing a defined gDNA mix of five microbes with a wide range of different GC contents (20-72%) when comparing to the expected distribution and Illumina MiSeq data from the same DNA pool...

The behavior of two-dimensional (2D) materials for energy-storage systems relates to their morphology and physicochemical properties. Although various 2D materials can be found in different fields, the open access of these materials has greatly hampered their practical applications, such as in lithium sulfur batteries, where the soluble intermediates should be controlled. Here, we have developed a facile approach to prepare 2D ultra-thin interconnected carbon fabrics (ICFs) with "bubble-like" morphology and abundant mesopores using a "blowing bubble" method...

BACKGROUND: Whether the benefits of phosphorus binders extend to those without end stage renal disease is uncertain. Among a large diverse non-dialysis chronic kidney disease (CKD) population with hyperphosphatemia, we sought to evaluate phosphorus binder use and compare mortality risk between patients prescribed and not prescribed binders. METHODS: A retrospective cohort study within an integrated health system (January 1, 1998 - December 31, 2012) among CKD patients (age ≥18) was performed...

We developed a simple and controlled method to synthesize FeCo2O4@MnO2 core-sheath nanoarchitecture (CSN) grown on the Ni foam. Ultrathin FeCo2O4 nanoflakes with an average thickness of 10 nm served as the scaffold to deposit MnO2 nanosheets. The MnO2 nanosheets were able to vertically grow on FeCo2O4 nanoflakes to form a sheath via a hydrothermal reaction. The nanocomposites' thickness can be tailored from 80 nm to 550 nm by changing the reaction times. Electrochemical measurements demonstrated that FeCo2O4@MnO2 CSN with an optimal thickness about 400 nm achieved an areal capacitance of 3...

Increasing age is tightly linked to decreased thickness of the human neocortex. The biological mechanisms that mediate this effect are hitherto unknown. The DNA methylome, as part of the epigenome, contributes significantly to age-related phenotypic changes. Here, we identify an epigenetic signature that is associated with cortical thickness (P=3.86 × 10(-8)) and memory performance in 533 healthy young adults. The epigenetic effect on cortical thickness was replicated in a sample comprising 596 participants with major depressive disorder and healthy controls...

Erythropoiesis-stimulating agents (ESAs) are not perfect, since they have potential side effects. Iron therapy is also receiving growing attention in recent years. Areas covered: We performed a literature search on PubMed using the following key words: anaemia, chronic kidney disease, HIF stabilisers, sotatercept, actin traps, iron, iron-containing phosphate binders, iron dialysate. We reviewed new drugs that are under clinical development to obtain better safety and activity and/or easier and cheaper manufacturing processes in comparison to available ESAs...

Next-generation sequencing (NGS) has been applied successfully to the field of therapeutic antibody discovery, often outperforming conventional screening campaigns which tend to identify only the more abundant selective antibody sequences. We used NGS to mine the functional nanobody repertoire from a phage-displayed camelid immune library directed to the recepteur d'origine nantais (RON) receptor kinase. Challenges to this application of NGS include accurate removal of read errors, correct identification of related sequences, and establishing meaningful inclusion criteria for sequences-of-interest...

Thermal behaviour and thermophysical properties of two typical cathodes for lithium-ion batteries were studied in dependence of temperature. The cathode materials are composite thick films containing a mixture of 90 wt% LiMeO2 active material (with Me = Co or Me = Ni + Mn + Co, respectively) and additives (binder and carbon black), deposited on aluminium current collector foils. The thermal conductivity of each cathode type and their corresponding composite layers were determined up to 573 K from the measured thermal diffusivity, the specific heat capacity and the estimated density based on metallographic methods and structural investigations...

Interconnected 3D network of reduced graphene oxide decorated with carbon dots (rGO/CDs) nanosheets are successfully fabricated via a simple one-pot hydrothermal process. The as-prepared rGO/CDs present appropriate 3D interconnected structure and abundant oxygen-containing functional groups, which attribute to excellent electrochemical performance such as high specific capacitance, good rate capability, and great cycling stability. Employed as binder-free electrodes for supercapacitor, the as-resulted rGO/CDs exhibit excellent long-term cycling stability (ca...

A number of studies have profiled G protein-coupled receptor (GPCR) conformation using fluorescent biaresenical hairpin binders (FlAsH) as acceptors for BRET or FRET. These conformation-sensitive biosensors allow reporting of movements occurring on the intracellular surface of a receptor to investigate mechanisms of receptor activation and function. Here, we generated eight FlAsH-BRET-based biosensors within the sequence of the β2-adrenergic receptor (β2AR) and compared agonist-induced responses to the angiotensin II receptor type I (AT1R) and the prostaglandin F2α receptor (FP)...

Approximately 1% of the global population suffers from epilepsy, a class of disorders characterized by recurrent and unpredictable seizures. Of these cases roughly one-third are refractory to current antiepileptic drugs, which typically target neuronal excitability directly. The events leading to seizure generation and epileptogenesis remain largely unknown, hindering development of new treatments. Some recent experimental models of epilepsy have provided compelling evidence that glial cells, especially astrocytes, could be central to seizure development...

PURPOSE: Phosphate binders (PB) have to be taken with food, their interference with an individual's lifestyle and social habits influences treatment adherence. Several PBs are available, and patient preferences should not be ignored when prescribing. The purpose was to know the extent of intentional and unintentional nonadherence to PB in hemodialysis (HD) patients, and to evaluate the long-term results (adherence, serum phosphate levels, and cost) of a strategy of prescription of PB that takes into account patient preferences...

Relationships between maternal education (ME) and both behavioral performances and brain activation during the discrimination of phonemic and nonphonemic sounds were examined using fMRI in children with different levels of phoneme categorization proficiency (CP). Significant relationships were found between ME and intellectual functioning and vocabulary, with a trend for phonological awareness. A significant interaction between CP and ME was seen for nonverbal reasoning abilities. In addition, fMRI analyses revealed a significant interaction between CP and ME for phonemic discrimination in left prefrontal cortex...

Ube2T is the E2 ubiquitin-conjugating enzyme of the Fanconi anemia DNA repair pathway and it's overexpressed in several cancers, representing an attractive target for the development of inhibitors. Despite the extensive efforts in targeting the ubiquitin system, very few E2 binders have currently been discovered. Herein we report the identification of a new allosteric pocket on Ube2T through a fragment screening using biophysical methods. Several fragments binding to this site inhibit ubiquitin conjugation in vitro...

The physical properties and mechanical integrity of pharmaceutical tablets are of major importance when loading with active pharmaceutical ingredient(s) (API) in order to ensure ease of processing, control of dosage and stability during transportation and handling prior to patient consumption. The interaction between API and excipient, acting as functional extender and binder, however, is little understood in this context. The API indomethacin is combined in this study with microcrystalline cellulose (MCC) at increasing loading levels...

Grahame J Elder, Jacqueline Center
Rising levels of serum phosphate occur late in the course of chronic kidney disease (CKD) and have been easy targets for nephrologists to treat using phosphate binding drugs, as well as fertile ground for the pharmaceutical industry, for meta-analysis and for the earnest pontifications of guideline writers. Unfortunately, the evidence does little to support this focus, which might be better applied to earlier, adaptive hormonal changes, and to phosphate balance rather than serum phosphate levels. Nevertheless, phosphate binders are ubiquitously prescribed to patients on dialysis, and often prescribed to patients with earlier stages of CKD; for which there is no evidence of benefit and some evidence that calcium-based binders (CBBs) and possibly non-CBBs may cause more harm than placebo...
