Impact of biochars on CO emissions and physic-chemical properties in Malaysian Tropical soils: Factor analysis and weighted contribution.

Global climate change is the most serious challenge that modern society faces. Soil-biochar carbon sequestration is a promising natural solution for capturing carbon. This study monitored the CO emissions of five biochar incubated Malaysian Tropical soils (MT-Soil).

Insights From Refusal Patterns for Deceased Donor Kidney Offers.

Background: The likelihood that a deceased donor kidney will be used evolves during the allocation process. Transplant centers can either decline an organ offer for a single patient or for multiple patients at the same time. We hypothesize that refusals for a single patient indicate issues with individual patients, whereas simultaneous refusals for multiple patients indicate issues with organ quality.

MnCoO as a Photothermal Modifier for BiVO Photoanode to Achieve Efficient Photoelectrochemical Water Oxidation.

Spinel oxides are widely used to enhance photoanodes' photoelectrochemical (PEC) water oxidation performance. In this paper, we demonstrate that a p-type photothermal MnCoO layer, inserted between BiVO and FeOOH cocatalysts, can significantly enhance PEC performance. On the one hand, the charge recombination is greatly suppressed since p-type MnCoO can form a p-n heterojunction with n-type BiVO.

Calcimimetic Prescriptions in Fee-for-Service Medicare Beneficiaries Undergoing Dialysis.

Importance: Calcimimetics are a mainstay of treatment for secondary hyperparathyroidism (sHPT), a ubiquitous condition in end-stage kidney disease (ESKD) associated with fractures, cardiovascular events, and mortality. In 2018, Medicare implemented the Transitional Drug Add-On Payment Adjustment (TDAPA), which shifted calcimimetic coverage from Part D prescription drug plans to Part B. Prior to TDAPA, Medicare beneficiaries with ESKD faced varying out-of-pocket costs for calcimimetics at the point of pharmacy depending on presence and magnitude of low-income subsidies (LISs).

Kidney Transplant Wait Times Under Waiting List Expansion Scenarios.

Importance: Kidney transplantation offers survival benefits and superior quality of life compared with maintenance dialysis for patients with end-stage kidney disease (ESKD), but it is limited to approximately 25 000 patients annually in the United States. Expanding access to transplant could be accomplished by allowing more patients to join the waiting list or by increasing organ supply.

Objective: To estimate how these interventions could affect transplant wait times.

The Final Rule in a Bind: What We Are Learning From Suboptimal Simultaneous Heart-Kidney Outcomes and Potential Solutions to the Problem.

Background: The 2018 revision of the adult Heart Allocation Policy (aHAP) led to a notable increase in the rate of simultaneous heart-kidney transplants (SHKT) in the United States. However, this policy has faced criticism for its inability to enhance post-transplant survival rates or decrease mortality among SHKT recipients on the waitlist, although high-quality kidneys are used.

Methods: We analyzed data from the Organ Procurement and Transplantation Network, covering 1549 SHKT cases from 2015 to 2021.

Photothermal effect and hole transport properties of polyaniline for enhanced photoelectrochemical water splitting of BiVO photoanode.

As modification strategies are actively developed, the photothermal effect is expected to be a viable way to enhance the PEC water splitting performance. Herein, we demonstrate that the photothermal polyaniline (PANI) layer inserted between CoF cocatalyst and BiVO can enhance the photocurrent density of pure BiVO by 3.50 times.

Research on Activation Mechanisms In Situ during Rapid Desorption of Mercury-Absorbing Activated Coke by the Heating Method.

The adsorption of active coke is a good method to control mercury in coal-fired power plants, but spent powdered activated coke (SPAC) will cause secondary pollution and waste of resources if it is not properly treated. The purpose of this study was to explore the desorption performance of SPAC when heated in a drop-tube reactor under different atmospheres. The carbon consumption was 0.

Evaluation and Management of Kidney Dysfunction in Advanced Heart Failure: A Scientific Statement From the American Heart Association.

Early identification of kidney dysfunction in patients with advanced heart failure is crucial for timely interventions. In addition to elevations in serum creatinine, kidney dysfunction encompasses inadequate maintenance of sodium and volume homeostasis, retention of uremic solutes, and disrupted endocrine functions. Hemodynamic derangements and maladaptive neurohormonal upregulations contribute to fluctuations in kidney indices and electrolytes that may recover with guideline-directed medical therapy.

Development of Preladenant-Based Radiotracers for Imaging AR in Tumors.

Activation of the adenosine 2A receptor (AR) can lead to tumor immunosuppression, which results in poor prognosis of immunotherapy. The aim of this study was to design novel F-labeled probes ([F]F-PFP and [F]F-PFP) to visualize AR in the tumor. The uptake of radioprobes in AR-negative 4T1 breast tumor was lower than that of AR-positive B16F10 melanoma at 1 h p.

An efficient molten steel slag gas quenching process: Integrating carbon solidification and waste heat recovery.

The iron and steel-making industries have garnered significant attention in research related to low-carbon transitions and the reuse of steel slag. This industry is known for its high carbon emissions and the substantial amount of steel slag it generates. To address these challenges, a waste heat recovery process route has been developed for molten steel slag, which integrates CO capture and fixation as well as efficient utilization of steel slag.

The Medical Costs of Determining Eligibility and Waiting for a Kidney Transplantation.

Background: Recent efforts to increase access to kidney transplant (KTx) in the United States include increasing referrals to transplant programs, leading to more pretransplant services. Transplant programs reconcile the costs of these services through the Organ Acquisition Cost Center (OACC).

Objective: The aim of this study was to determine the costs associated with pretransplant services by applying microeconomic methods to OACC costs reported by transplant hospitals.

Immunologic Benefits of 0-antigen Mismatched Transplants: No Added Boost for Racial and Ethnic Minorities.

Background: Systemic barriers to posttransplant care, including access to immunosuppressant medications, contribute to higher rates of kidney transplant failure in racial minorities. Matching donor and recipient HLA alleles reduce allorecognition, easing reliance on immunosuppression. We hypothesize that 0-antigen mismatch transplants may provide stronger protection against graft loss in racial minorities.

Microstructure regulation and enhanced VOC removal performance of carbon aerogels by surface carbon nanotube grown.

Carbon aerogels were newly employed in adsorption for volatile organic compounds (VOCs) as an emerging material. In contrast, the microstructure and high carbon consumption are the primary factors restricting their application scenarios. Carbon nanotubes, recognized for their controllable cylindrical hollow structure and hydrophobic walls, generally possess higher adsorption capacities than typical carbon adsorbents.

Referral and Beyond: Restructuring the Kidney Transplant Process to Support Greater Access in the United States.

Advocates for improved equity in kidney transplants in the United States have recently focused their efforts on initiatives to increase referral for transplant evaluation. However, because donor kidneys remain scarce, increased referrals are likely to result in an increasing number of patients proceeding through the evaluation process without ultimately receiving a kidney. Unfortunately, the process of referral and evaluation can be highly resource-intensive for patients, families, transplant programs, and payers.

Preparation and characterization of P-type zeolite for adsorption of Cr, Ni, and Co.

Acid-washed coal fly ash (AW-CFA) was subjected to wet grinding activation followed by hydrothermal crystallization to synthesize P zeolite (FAZ-P). The FAZ-P obtained at 120 °C for 24 h exhibited a maximum relative crystallinity of 93.15% and was employed for the adsorption of Cr, Ni, and Co from aqueous solutions.

Comparative Study of Radioiodinated Folate Receptor Targeting Albumin Probes for Atherosclerosis Plaque Imaging.

The objective of this study is to compare a series of albumin-based folate radiotracers for the potential imaging of folate receptor (FR) positive macrophages in advanced atherosclerotic plaques. Diversified radioiodinated FR-targeting albumin-binding probes ([I]IBAHF, [I]IBHF, and [I]HF) were developed through various strategies. Among the three radiotracers, [I]IBAHF and [I]IBHF showed excellent stability (>98%) in saline and PBS 7.
