Canopy openness rather than tree species determines atmospheric deposition into forests.

Atmospheric nutrient deposition plays a crucial role in supplying nutrients to forests on poor soils, making it a key factor in maintaining nutrient stocks and forest productivity. We compared total atmospheric deposition in production forests of European beech (Fagus sylvatica), Douglas fir (Pseudotsuga menziesii), and Scots pine (Pinus sylvestris) by measuring bulk deposition and throughfall while accounting for canopy exchange. We assessed the differences in total deposition resulting from forest management practices such as high-thinning, shelterwood and clearcutting, on forest structure for both macronutrients and micronutrients in areas exposed to high nutrient deposition.

Addressing the challenges of integrating digital health technologies to measure patient-centred outcomes in clinical registries.

Longitudinal patient registries generate important evidence for advancing clinical care and the regulatory evaluation of health-care products. Most national registries rely on data collected as part of routine clinical encounters, an approach that does not capture real-world, patient-centred outcomes, such as physical activity, fatigue, ability to do daily tasks, and other indicators of quality of life. Digital health technologies that obtain such real-world data could greatly enhance patient registries but unresolved challenges have so far prevented their broad adoption.

The intestinal flora: The key to unraveling heterogeneity in immune thrombocytopenia?

Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder characterized by enhanced platelet destruction and impaired platelet production, due to a loss of immune tolerance that leads to targeting of platelets and megakaryocytes by glycoprotein-autoantibodies and/or cytotoxic T cells. There is a high degree of heterogeneity in ITP patients signified by unpredictable disease trajectories and treatment responses. Initial studies in humans have identified intestinal microbiota perturbance in ITP.

Subcutaneous Implantation of Open Microwell Islet Delivery Devices in Pigs.

Background: Intraportal pancreatic islet transplantation is a treatment option for patients with severe beta cell failure and unstable glycemic control. However, this procedure is associated with loss of beta cells after intrahepatic transplantation. Islet delivery devices (IDDs) implanted at extrahepatic sites may support engraftment and improve survival of pancreatic islets.

Determining the posture and location of pigs using an object detection model under different lighting conditions.

Computer vision techniques are becoming increasingly popular for monitoring pig behavior. For instance, object detection models allow us to detect the presence of pigs, their location, and their posture. The performance of object detection models can be affected by variations in lighting conditions (e.

Prognostic value of radiologic and pathological response in colorectal cancer liver metastases upon systemic induction treatment: subgroup analysis of the CAIRO5 trial.

Background: RECIST may not be optimal for assessing treatment response with current systemic regimens. We evaluated RECIST, morphologic, and pathologically documented response (pathological response) in patients with initially unresectable colorectal cancer liver-only metastases (CRLM).

Patients And Methods: Four hundred and eighty-nine patients from the phase III CAIRO5 trial were included who were treated with FOLFOX/FOLFIRI/FOLFOXIRI and bevacizumab or panitumumab.

Exploring clinical chemistry markers in amyotrophic lateral sclerosis: insights into survival and disease trajectories.

Objective: Commonly measured clinical chemistry markers might be indicative of survival and disease progression in amyotrophic lateral sclerosis (ALS).

Methods: In a cohort study of 270 ALS patients diagnosed from April 2014 to May 2021 in Stockholm, Sweden, we examined the link between 29 clinical chemistry markers at diagnosis and mortality risk at 6 months, 1 year, and 3 years after diagnosis. Summary variables from exploratory factor analysis (EFA) assessed the markers' collective impact on survival.

Detecting Colorectal Neoplasia Using Specific Fecal Fluorogenic Protease-Sensitive Substrates: A Pilot Study.

Background: identification and removal of advanced adenomas (AA) reduce colorectal cancer (CRC) incidence and potentially mortality. CRC screening often uses fecal immunochemical testing to select high-risk individuals for colonoscopy, despite its low sensitivity for AA and relatively high false-positivity rate. Previous studies have linked proteases to CRC development through their ability to facilitate angiogenesis and immunoregulation.

Comparative iron management in hemodialysis and peritoneal dialysis patients: a systematic review.

Background: Patients with kidney failure undergoing dialysis often suffer from anemia. Iron deficiency, along with a shortage in erythropoietin, is a common cause. Peritoneal dialysis (PD) patients may have a different iron metabolism compared to hemodialysis (HD) patients.

Large-scale brainstem neuroimaging and genetic analyses provide new insights into the neuronal mechanisms of hypertension.

While brainstem regions are central regulators of blood pressure, the neuronal mechanisms underlying their role in hypertension remain poorly understood. Here, we investigated the structural and genetic relationships between global and regional brainstem volumes and blood pressure. We used magnetic resonance imaging data from n = 32,666 UK Biobank participants, and assessed the association of volumes of the whole brainstem and its main regions with blood pressure.

Neutralizing GDF-15 can overcome anti-PD-1 and anti-PD-L1 resistance in solid tumours.

Cancer immunotherapies with antibodies blocking immune checkpoint molecules are clinically active across multiple cancer entities and have markedly improved cancer treatment. Yet, response rates are still limited, and tumour progression commonly occurs. Soluble and cell-bound factors in the tumour microenvironment negatively affect cancer immunity.

Long-term mental health outcomes after corneal transplantation and potential predictors: A multicentre prospective cohort study.

Introduction: To evaluate the long-term effect of corneal transplantation on mental health outcomes and to assess potential predictors of these outcomes.

Methods: For this multicentre prospective cohort study, patients awaiting corneal transplantation were recruited from 11 (academic) hospitals and eye clinics in the Netherlands. Participants (n = 238) completed the Centre for Epidemiological Studies Depression scale (CES-D), the Hospital Anxiety and Depression Scale-Anxiety subscale (HADS-A) and the Dutch ICF Activity Inventory Emotional Health subscale (DAI-EH) and Fatigue subscale (DAI-F) 1 month prior and 3, 6, 12 and 24 months after corneal transplantation.

Biosynthesis of Antimicrobial Ornithine-Containing Lacticin 481 Analogues by Use of a Combinatorial Biosynthetic Pathway in .

Lacticin 481, a ribosomally synthesized and post-translationally modified peptide (RiPP), exhibits antimicrobial activity, for which its characteristic lanthionine and methyllanthionine ring structures are essential. The post-translational introduction of (methyl)lanthionines in lacticin 481 is catalyzed by the enzyme LctM. In addition to macrocycle formation, various other post-translational modifications can enhance and modulate the chemical and functional diversity of antimicrobial peptides.

Urea hydrogen-bond donor strengths: bigger is not always better.

The hydrogen-bond donor strength of ureas, widely used in hydrogen-bond donor catalysis, molecular recognition, and self-assembly, can be enhanced by increasing the size of the chalcogen X in the CX bond from O to S to Se and by introducing more electron-withdrawing substituents because both modifications increase the positive charge on the NH groups which become better hydrogen-bond donors. However, in 1,3-diaryl X-ureas, a steric mechanism disrupts the positive additivity of these two tuning factors, as revealed by our quantum-chemical analyses. This leads to an enhanced hydrogen-bond donor strength, despite a lower NH acidity, for 1,3-diaryl substituted O-ureas compared to the S- and Se-urea analogs.

Microplastic analysis in soils: A comparative assessment.

Microplastic (MiP) contamination poses environmental risks, but harmonizing data from different quantification methods and sample matrices remains challenging. We compared analytical protocols for MiP quantification in soil, consisting of Digital, Fluorescence, Fourier-transform infrared (FTIR), and Raman Microscopy as well as quantitative Pyrolysis-Gas Chromatography-Mass Spectroscopy (Py-GC-MS) and 1-proton nuclear magnetic resonance (H NMR) spectroscopy as detection techniques. Each technique was coupled with a specific extraction procedure and evaluated for three soils with different textures and organic carbon contents, amended with eight types of large MiPs (0.

PSMA - Targeted Clinical Molecular Imaging of Atherosclerosis: Correlation with Cardiovascular Risk Factors.

Aim: The early diagnosis of atherosclerotic changes to prevent ischemic events represents a clinical challenge.Prostate-specific membrane antigen (PSMA) as an established diagnostic in the field of prostate cancer also appears to detect neovascularization and inflammation in other diseases. We hypothesized that it might be also suited for detection of inflammation in atherosclerosis.

Kinetic and isotherm study for the adsorption of per- and polyfluoroalkyl substances (PFAS) on activated carbon in the low ng/L range.

Activated carbon adsorption is a widely used technology for the removal of per- and polyfluoroalkyl substances (PFAS). However, the rapid breakthrough of PFAS in activated carbon filters poses a challenge to meet the very low allowable PFAS concentrations in drinking water, leading to high operational costs. In this study, we conducted batch isotherm and kinetic adsorption experiments using nine different types of PFAS molecules at concentrations typically found in water sources used for drinking water production (0.

CNN-Based Device-Agnostic Feature Extraction From ONH OCT Scans.

Purpose: Optical coherence tomography (OCT)-derived measurements of the optic nerve head (ONH) from different devices are not interchangeable. This poses challenges to patient follow-up and collaborative studies. Here, we present a device-agnostic method for the extraction of OCT biomarkers using artificial intelligence.

Analytical and Pharmacological Characterization of 1-(Furan-2-Carbonyl)-LSD (1F-LSD) and Comparison With 1-(Thiophene-2-Carbonyl)-LSD (1T-LSD).

The classical psychedelic drug (+)-lysergic acid diethylamide (LSD) continues to attract considerable multidisciplinary interest, and over the last eight decades, many derivatives and analogs of LSD have been synthesized. One site on the ergoline scaffold of LSD that has been frequently modified is the N-position, with the N-acylated LSD derivative 1-acetyl-LSD (1A-LSD, ALD-52) being one of the earliest examples. In more recent years, several other alkylcarbonyl- and cycloalkylcarbonyl-substituted LSD derivatives have been evaluated, including several distributed as research chemicals.

The eating rate of bread predicted from its sensory texture and physical properties.

Eating rate (ER) can moderate energy intake and ER can be modified by the texture and physical properties of food. However, the magnitude of the effects is not well known. The aim of this study was to investigate how bread texture and physical properties determine ER.
