The study of degradation behavior of electrocatalysts in an industrial context calls for rapid and efficient analysis methods. Optical methods like Raman spectroscopy fulfil these requirements and are thus predestined for this purpose. However, the iridium utilized in proton exchange membrane electrolysis (PEMEL) is Raman inactive in its metallic state.
View Article and Find Full Text PDFImmune dysregulation in the brain and periphery is thought to contribute to the detrimental neurodegeneration that occurs in Parkinson's disease (PD). Identifying mechanisms to reverse this dysregulation is key to developing disease-altering therapeutics for this currently incurable disease. Here we utilized the longitudinal data from the Parkinson's Progression Marker Initiative to demonstrate that circulating lymphocytes progressively decline in PD and can be used to predict future motor symptom progression.

The shortage of organs and long waiting times mean that many patients arrive at the transplant with a significant level of deterioration. The objective was to analyze the relationship between socioeconomic variables and knowledge about pre-emptive kidney transplant in the pre-transplant consultation.

After careful instruction, patients can administer the treatment themselves. We previously reported data of 101 patients (Klimas et al.
View Article and Find Full Text PDFThe liver is the central metabolic organ and produces 85-90% of the proteins found in plasma. Accordingly, the plasma proteome is an attractive source of liver disease biomarkers that reflects the different cell types present in this organ, as well as the processes such as responses to acute and chronic injury or the formation of an extracellular matrix. In the first part, we summarize the biomarkers routinely used in clinical evaluations and their biological relevance in the different stages of non-malignant liver disease.

We hypothesized that patients with bladder cancer benefit from [ Ga]Ga-FAPI-46 PET/CT prior to radical cystectomy for locoregional lymph node staging.
Materials And Methods: Eighteen patients underwent [ Ga]Ga-FAPI-46 PET/CT for evaluation of lymph node (LN) status in predefined LN regions.
Inflammation in the brain and gut is a critical component of several neurological diseases, such as Parkinson's disease (PD). One trigger of the immune system in PD is aggregation of the pre-synaptic protein, α-synuclein (αSyn). Understanding the mechanism of propagation of αSyn aggregates is essential to developing disease-modifying therapeutics.

Patients with a first diagnosis (FD) of BC or radical cystectomy (RC) were included in a prospective, monocentric, observational study. Drugs and medical data was assessed at start and three-monthly for 24 months.

RED is in practice determined indirectly from calibrated CT Hounsfield Units (HU). While CT images provide useful 3D information, the spectral differences between CT and clinical LINAC beams may impact the validity of the CT-ED calibration, especially in the context of novel tissue-mimicking materials where deviations from biologically typical atomic number to atomic weight ratios 〈Z/A〉 occur and/or high-Z materials are present.

Timely interventions have a proven benefit for people experiencing psychotic illness. One bottleneck to accessing timely interventions is the referral process to the specialist team for early psychosis (STEP). Many general practitioners lack awareness or confidence in recognising psychotic symptoms or state.

This study examined the relationship between multisensory emotion processing and intrusive memories over seven days following exposure to an analogue trauma in a sample of 55 healthy young adults. We used an adapted version of the trauma film paradigm, where scenes showing a car accident trauma were presented using virtual reality, rather than a conventional 2D film.
View Article and Find Full Text PDFWe present a Quality by Design (QbD) styled approach for optimizing lipid nanoparticle (LNP) formulations, aiming to offer scientists an accessible workflow. The inherent restriction in these studies, where the molar ratios of ionizable, helper, and PEG lipids must add up to 100%, requires specialized design and analysis methods to accommodate this mixture constraint. Focusing on lipid and process factors that are commonly used in LNP design optimization, we provide steps that avoid many of the difficulties that traditionally arise in the design and analysis of mixture-process experiments by employing space-filling designs and utilizing the recently developed statistical framework of self-validated ensemble models (SVEM).

Patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) often report a fluctuation of symptoms throughout one treatment cycle with intravenous immunoglobulins (IVIG). The aim of this study was to determine whether sNfL is suitable to quantify patient-reported symptom fluctuations.

Field-effect transistors (FETs) based on atomically thin two-dimensional (2D) semiconductors such as monolayer MoS are no exception. Probing defect dynamics in 2D FETs is therefore of significant interest.

Currently, diagnostic criteria for ADHD mainly reflect behavioral symptoms, neglecting internal phenomena like mind-wandering. Recent studies found that mind-wandering explains impairment beyond ADHD symptoms in adults. To better capture ADHD-related impairment in adolescents, we aimed to elucidate whether mind-wandering is associated with impairments that are prevalent in adolescents (i.

This study investigated the concurrent and prospective relationship of both trait and daily rumination with daily perceived maternal bonding and mood. Ninety-three mothers of infants aged between 3 and 14 months completed a ten-day diary study investigating the relationship between daily and trait ruminative self-focus, negative affect and perceived maternal bonding, or her perceived feelings of closeness with her infant.

In the diabetes group, sympathetic skin response (SSR) was measured as an indicator for autonomic neuropathy.

An improved understanding of the multifactorial developmental pathways that explain how these factors predict depression could inform intervention strategies.
Methods: Using structural equation modeling, this study explored whether self-evaluation and interpersonal factors were associated with adolescent depressive symptoms in a population-based sample (n = 11,921; Avon Longitudinal Study of Parents and Children, ALSPAC), across four development stages: early and late childhood plus early and middle adolescence from 3 to 17 years old.

Therefore, we aimed to analyze outcomes and prognostic factors of patients with urothelial carcinoma (UC) undergoing RC and T0 in the final histology without neoadjuvant chemotherapy at a high-volume academic center.
Patients And Methods: We retrospectively analyzed patients undergoing RC for pure UC between 2004 and 2020.
