High-flux hemodialysis (HD) and high-dose hemodiafiltration (HDF) are established treatments for patients with kidney failure. Since HDF has been associated with improved survival rates compared to HD, we evaluated the cost-effectiveness of HDF compared to HD. Cost-utility analyses were performed from a societal perspective alongside the multinational randomized controlled CONVINCE trial.

Current research on common parasitic nematodes is limited because their infective stages cannot be propagated in vitro. Here, we report a culture system for developing L4s of Haemonchus contortus, a blood-feeding nematode of ruminants. Our results demonstrated that a proportionate mixture of NCTC-109 to Luria-Bertini (1:2) media promoted the formation of early L4s and then into late L4s upon inclusion of 12.

In this study, the logarithm of the -octanol:water partition coefficient (log) and the blood-to-plasma concentration ratio ( ) were for the first time experimentally determined for the pyrrolizidine alkaloids (PAs) intermedine, lasiocarpine, monocrotaline, retrorsine and their -oxides (PANOs). Validated assays for log (miniaturized shake-flask method) and (LC-MS/MS-based depletion assay) determination were compared to an ensemble of models.

Background: Despite remarkable clinical efficacy, little is known about the system-wide immunological alterations provoked by PD1 blockade. Dynamics of quantitative immune composition and functional repertoire during PD1 blockade could delineate cohort-specific patterns of treatment response and therapy-induced toxicity.
Methods: We longitudinally assessed therapy-induced effects on the immune system in fresh whole blood using flow cytometry-based cell quantifications, accompanied by analyses of effector properties of all major immune populations upon cell-type specific stimulations.

Background: People with MS show abnormal thinning of the retinal layers, which is associated with clinical disability and brain atrophy, and is a potential surrogate marker of neurodegeneration and treatment effects.
Objective: To evaluate the utility of retinal thickness as a surrogate marker of neurodegeneration and treatment effect in participants with secondary progressive MS (SPMS) from the optical coherence tomography (OCT) substudy of the EXPAND Phase 3 clinical trial (siponimod versus placebo).
Methods: In the OCT substudy population (n = 159), treatment effects on change in the average thickness of the retinal layer, peripapillary retinal nerve fiber layer (pRNFL), and combined macular ganglion cell and inner plexiform layers (GCIPL) were analyzed by high-definition spectral domain OCT at months 3, 12, and 24.

We investigate the effect of focused-ion-beam (FIB) irradiation on spin waves with sub-micron wavelengths in Yttrium-Iron-Garnet (YIG) films. Time-resolved scanning transmission X-ray (TR-STXM) microscopy was used to image the spin waves in irradiated regions and deduce corresponding changes in the magnetic parameters of the film. We find that the changes of Gairradiation can be understood by assuming a few percent change in the effective magnetizationof the film due to a trade-off between changes in anisotropy and effective film thickness.

We show that differences in circulating androgens between the three male mating morphs in ruff sandpipers are linked to 17-beta hydroxysteroid dehydrogenase 2 (HSD17B2), encoded by a gene within the supergene that determines the morphs. Low-testosterone males had higher expression in blood than high-testosterone males, as well as in brain areas related to social behaviors and testosterone production.

Background And Objectives: Recently, reduction of transcallosal inhibition by contralateral navigated repetitive transcranial magnetic stimulation (nrTMS) improved neurorehabilitation of glioma patients with new postoperative paresis. This multicentric study examines the effect of postoperative nrTMS in brain tumor patients to treat surgery-related upper extremity paresis.
Methods: This is a secondary analysis of two randomized and three one-arm studies in brain tumor patients with new/progressive postoperative paresis.

This report presents the case of a benign metanephric stromal tumor that occurred in the kidney of a 5-year-old boy and in which differentiation from a nephroblastoma was successful. Radiological assessment played the decisive role in this case, as the low initial volume, a high apparent diffusion coefficient, and lack of rapid tumor growth were considered atypical for a nephroblastoma. The boy underwent successful kidney-preserving resection without neoadjuvant chemotherapy, and intraoperative contrast-enhanced ultrasound examination helped to accurately define the tumor margins.

Miniaturization of next-generation active neural implants requires novel micro-packaging solutions that can maintain their long-term coating performance in the body. This work presents two thin-film coatings and evaluates their biostability and in vivo performance over a 7-month animal study. To evaluate the coatings on representative surfaces, two silicon microchips with different surface microtopography are used.

Confocal microscopy is an invaluable tool for studying fluorescent materials and finds a wide application in biology and in quantum sensing. Usually, these experiments are performed under ambient conditions, but many materials are air sensitive (for example, black phosphorus) and degrade quickly under the strong laser irradiance. Here, we present a glovebox-integrated confocal microscope designed for nitrogen-vacancy (NV) center-based nano-scale sensing and NMR spectroscopy in an inert gas atmosphere.

: Chronic low back pain (CLBP) is prevalent among older adults and leads to significant functional limitations and reduced quality of life. Segmental stabilization exercises (SSEs) are commonly used to treat CLBP, but the selective activation of deep abdominal muscles during these exercises can be challenging for patients. To support muscle activation, physiotherapists use biofeedback methods such as palpation and ultrasound imaging.

This review describes mass spectrometry (MS)-based approaches for the absolute quantification of therapeutic monoclonal antibodies (mAbs), focusing on technical challenges in sample treatment and calibration. Therapeutic mAbs are crucial for treating cancer and inflammatory, infectious, and autoimmune diseases. We trace their development from hybridoma technology and the first murine mAbs in 1975 to today's chimeric and fully human mAbs.

Per- and polyfluoroalkyl substances (PFAS) are a class of persistent organic pollutants that pose a growing threat to environmental and human health. Soil acts as a long-term reservoir for PFAS, potentially impacting soil biodiversity and ecosystem function. Earthworms, as keystone species in soil ecosystems, are particularly vulnerable to PFAS exposure.
