Physical Frailty Predicts Outcomes in Patients Undergoing Evaluation for Kidney Transplantation.

Introduction: An increasing number of older patients are undergoing evaluation for kidney transplantation; however, older patients experience increased rates of complications compared with younger patients, leading to the study of frailty assessments. Although many centers have evaluated the Fried Frailty Phenotype (FFP), less is known about the ability of the Short Performance Physical Battery (SPPB) to predict outcomes.

Methods: Frailty assessment by FFP and SPPB was introduced into routine outpatient evaluation for patients aged 55 years and older referred for transplantation.

Synthesis of LiMnNbO disordered rock-salt under reducing conditions for Li-ion batteries.

A Mn-Li-Nb disordered rock-salt oxide cathode is prepared by a solid-state reaction under 5% H/N, and its electrochemical property shows a high voltage plateau at 4.8 V, with irreversible structural changes in the 1st cycle due to O redox processes; this is supported by powder X-ray diffraction and laboratory Mn K-edge XANES data.

Propofol for treatment resistant depression: A randomized controlled trial.

Background: Anesthetic agents including ketamine and nitrous oxide have shown antidepressant properties when appropriately dosed. Our recent open-label trial of propofol, an intravenous anesthetic known to elicit transient positive mood effects, suggested that it may also produce robust and durable antidepressant effects when administered at a high dose that elicits an electroencephalographic (EEG) burst-suppression state. Here we report findings from a randomized controlled trial ( NCT03684447 ) that compared two doses of propofol.

Structural and electrochemical insights into novel Wadsley Roth NbTiMoO and TaTiMoO anodes for Li-ion battery application.

Niobium based anodes are gaining increasing popularity for application in high-power lithium-ion batteries, due to their high theoretical capacities, inherent safety at high current densities, and long-term stability. Here, we report the discovery and characterisation of a new Wadsley Roth niobate system, NbTiMoO, showing that it is isostructural with known systems: NbPO and NbVO. To evaluate the material's electrochemical performance, including performance at high current densities (for potential high power applications), and long-term stability, Li half-coin cells were prepared.

Multiscale dynamics of charging and plating in graphite electrodes coupling operando microscopy and phase-field modelling.

The phase separation dynamics in graphitic anodes significantly affects lithium plating propensity, which is the major degradation mechanism that impairs the safety and fast charge capabilities of automotive lithium-ion batteries. In this study, we present comprehensive investigation employing operando high-resolution optical microscopy combined with non-equilibrium thermodynamics implemented in a multi-dimensional (1D+1D to 3D) phase-field modeling framework to reveal the rate-dependent spatial dynamics of phase separation and plating in graphite electrodes. Here we visualize and provide mechanistic understanding of the multistage phase separation, plating, inter/intra-particle lithium exchange and plated lithium back-intercalation phenomena.

Gut microbiomes of captive primates show phylosymbiosis, respond to dietary sugar reduction, and select for host-specific dietary microbes.

Host-associated microbiomes are influenced by evolutionary history and proximate factors such as diet and environment. Zoos house animals in relatively standardized and manipulatable environments, making zoo populations valuable for studying microbiomes. Using a small population of five, closely related primate species housed under nearly identical environments, we investigated gut microbiome variation regarding (a) congruence between host evolutionary history and gut bacterial composition (i.

Fecal microbiota transplants modulate the gut microbiome of a two-toed sloth (Choloepus didactylus).

The microbes inhabiting an animal's gastrointestinal tracts, collectively known as the gut microbiome, are vital to animal health and wellbeing. For animals experiencing gut distress or infection, modulation of the gut microbiome, for example, via fecal microbiota transplant (FMT), provides a possible disease prevention and treatment method. The beneficial microbes present in the donor's transplanted feces can help combat pathogens, assist in digestion, and rebalance the recipient's microbiota.

CPR in correctional facilities: a missed opportunity?

In the incarcerated population, the largest ethnic and racial group is Black people. Heart disease is known as the leading causes of death in the United States which can lead to cardiac arrest. Layperson cardiopulmonary resuscitation (CPR) has been shown to provide a benefit and increase likelihood of return of spontaneous circulation (ROSC).

Reclaimed and Up-Cycled Cathodes for Lithium-Ion Batteries.

As electric vehicles become more widely used, there is a higher demand for lithium-ion batteries (LIBs) and hence a greater incentive to find better ways to recycle these at their end-of-life (EOL). This work focuses on the process of reclamation and re-use of cathode material from LIBs. Black mass containing mixed LiMnO and NiCoAlO from a Nissan Leaf pouch cell are recovered via two different recycling routes, shredding or disassembly.

Sustainable Upcycling of Spent Electric Vehicle Anodes into Solution-Processable Graphene Nanomaterials.

A major transition to electric vehicles (EVs) is underway globally, as countries target reductions in greenhouse gas emissions from the transport sector. As this rapid growth continues, significant challenges remain around how to sustainably manage the accompanying large volumes of waste from end-of-life lithium-ion batteries that contain valuable rare earth and critical materials. Here, we show that high-shear exfoliation in aqueous surfactants can upcycle spent graphite anodes recovered from an EV into few-layer graphene dispersions.

Optimization of Electrode and Cell Design for Ultrafast-Charging Lithium-Ion Batteries Based on Molybdenum Niobium Oxide Anodes.

Niobium oxides are an emerging class of anode materials for use in high-power lithium-ion batteries. Galvanostatic cycling and electrochemical impedance spectroscopy (EIS) were used in this study to investigate the influence of electrode porosity, electrode mass ratio, and cycling rate on the capacity, cycle life, and ionic conductivity of Li-ion battery cells based on a modified micron-sized MoNbO (MNO) anode powder. Both electrode and cell designs were found to have a significant impact on the rate performance and cycle life of Li-ion half- and full cells.

Mechanism of gelation in high nickel content cathode slurries for sodium-ion batteries.

Sodium-ion batteries are a prospective sustainable alternative to the ubiquitous lithium-ion batteries due to the abundancy of sodium, and their cobalt free cathodes. The high nickel O3-type oxides show promising energy densities, however, a time dependency in the rheological properties of the composite electrode slurries is observed, which leads to inhomogeneous coatings being produced. A combination of electron microscopy and infra-red spectroscopy were used to monitor the O3-oxide surface changes upon exposure to air, and the effect upon the rheology and stability of the inks was investigated.

Transient ice loss in the Patagonia Icefields during the 2015-2016 El Niño event.

The Patagonia Icefields (PIF) are the largest non-polar ice mass in the southern hemisphere. The icefields cover an area of approximately 16,500 km and are divided into the northern and southern icefields, which are ~ 4000 km and ~ 12,500 km, respectively. While both icefields have been losing mass rapidly, their responsiveness to various climate drivers, such as the El Niño-Southern Oscillation, is not well understood.

Enzymatic generation of short chain cello-oligosaccharides from Miscanthus using different pretreatments.

Enzyme combinations producing short-chain cello-oligosaccharides (COS) as major bio-products from cellulose of Miscanthus Mx2779 accessed through different pretreatment methods were compared. Over short hydrolysis times, processive endoglucanase TfCel9a produced a high percentage of cellotetraose and cellopentaose and is synergistic with endoglucanase CcCel9m for producing short oligomers from amorphous cellulose but had low activity on untreated Miscanthus. Hydrolysis of the latter improved when these were combined with a mutant cellobio/triohydrolase OsCelC7(-105) and a lytic polysaccharide monooxygenase TrCel61a, a combination which also produced the highest COS yields from phosphoric acid swollen cellulose.

High-Voltage Stabilization of O3-Type Layered Oxide for Sodium-Ion Batteries by Simultaneous Tin Dual Modification.

O3-type layered oxide materials are considered to be a highly suitable cathode for sodium-ion batteries (NIBs) due to their appreciable specific capacity and energy density. However, rapid capacity fading caused by serious structural changes and interfacial degradation hampers their use. A novel Sn-modified O3-type layered NaNiFeMnO cathode is presented, with improved high-voltage stability through simultaneous bulk Sn doping and surface coating in a scalable one-step process.

Xylo-Oligosaccharide Utilization by Engineered to Produce Ethanol.

The engineering of xylo-oligosaccharide-consuming strains is a promising approach for more effective utilization of lignocellulosic biomass and the development of economic industrial fermentation processes. Extending the sugar consumption range without catabolite repression by including the metabolism of oligomers instead of only monomers would significantly improve second-generation ethanol production This review focuses on different aspects of the action mechanisms of xylan-degrading enzymes from bacteria and fungi, and their insertion in strains to obtain microbial cell factories able of consume these complex sugars and convert them to ethanol. Emphasis is given to different strategies for ethanol production from both extracellular and intracellular xylo-oligosaccharide utilization by strains.
