Molecular docking to investigate HLA-associated idiosyncratic drug reactions.

Idiosyncratic drug reactions (IDRs) pose severe threats to patient health. Unlike conventionally dose-dependent side effects, they are unpredictable and frequently manifest as life-threatening conditions, such as severe cutaneous adverse reactions (SCARs) and drug-induced liver injury (DILI). Some HLA alleles, such as , , and , are known risk factors for adverse reactions induced by multiple drugs.

Genotoxicity testing of the anthraquinone dye Alizarin Red S.

The anthraquinone dye Alizarin Red S (ARS) is used for marking live animals, specifically as a tool for monitoring the stock of the endangered European eel by marking caught fish with ARS before releasing the eels back into the wild. As ARS can be found in recaptured eels even years later, knowledge of potential health hazards of ARS is essential for assessing the food safety of eels marked with ARS. As the compound class of anthraquinones is known for their genotoxic and carcinogenic properties, concerns were raised regarding the food safety of marked eels.

Impact of disease-modifying therapies on pregnancy outcomes in multiple sclerosis: a prospective cohort study from the German multiple sclerosis and pregnancy registry.

Background: In recent decades, relapsing remitting multiple sclerosis (MS) became more treatable through new disease-modifying therapies (DMTs). Identifying safe treatments with minimal fetal risks for family planning is needed.

Methods: In this prospective cohort from the German MS and Pregnancy Registry (DMSKW), we analyzed pregnancy and neonatal outcomes in MS-patients using descriptive statistics and logistic/linear regression models to compare DMT-exposed pregnancies to DMT-unexposed pregnancies.

Weekly Intraperitoneal Injection of Tamoxifen in an Inducible In Vivo Model of Junctional Epidermolysis Bullosa Generates Early and Advanced Disease Phenotypes.

Junctional epidermolysis bullosa caused by loss-of-function variants in genes encoding the skin basement membrane proteins laminin 332, type XVII collagen, or integrin α6β4 affects patients from birth with severe blistering, eventually leading to scarring and early lethality. In this study, we have optimized a previously published junctional epidermolysis bullosa-knockout mouse model with weekly tamoxifen intraperitoneal injections, resulting in a more controllable and severe model. Owing to the titratable dosing, this model now recapitulates both early and advanced stages of the human disease, strengthening its use in therapeutic studies.

Endovascular therapy for iatrogenic occlusion of the popliteal artery after complex total knee arthroplasty: A case report.

Iatrogenic arterial injury is an infrequent but limb-threatening complication of total knee arthroplasty (TKA). Open surgical reconstruction may not always be feasible or optimal, particularly in patients who have recently just undergone complex TKA procedures. In this report, we describe the treatment of a patient who developed popliteal artery occlusion following a complex TKA procedure performed the previous day.

Combining Cre-LoxP and single-cell sequencing technologies: insights into the extracellular vesicle cargo transfer.

The recent study from the Pogge von Strandmann group published in , by Alashkar Alhamwe ., combined for the first time the Cre-LoxP recombination system with single-cell sequencing. The group monitored the tumor-derived extracellular vesicle (EV) uptake and the EV functions in the recipient non-malignant cells in a pancreatic ductal adenocarcinoma mouse model.

Impact of exogenous rhamnolipids on plant photosynthesis and biochemical parameters under prolonged heat stress.

High temperatures severely affect plant growth and development leading to major yield losses. These temperatures are expected to increase further due to global warming, with longer and more frequent heat waves. Rhamnolipids (RLs) are known to protect several plants against various pathogens.

Modifiable risk factors and symptom progression in dementia over up to 8 years-Results of the DelpHi-MV trial.

Introduction: This study investigated the association between modifiable factors and symptom progression in dementia over up to 8 years.

Methods: Multilevel growth curve models assessed the role of modifiable risk factors (low education, hearing impairment and its treatment, depression, physical inactivity, diabetes and its treatment, smoking, hypertension and its treatment, obesity, alcohol consumption, social isolation, and visual impairment) on cognitive and functional trajectories in 353 people with dementia.

Results: Higher education was associated with higher initial cognitive status but faster decline.

Enhancing NK cell-mediated tumor killing of B7-H6 cells with bispecific antibodies targeting allosteric sites of NKp30.

In this work, we report the discovery and engineering of allosteric variable domains of the heavy chain (VHHs) derived from camelid immunization targeting NKp30, an activating receptor on natural killer (NK) cells. The aim was to enhance NK cell-mediated killing capacities by identifying VHHs that do not compete with the natural ligand of NKp30:B7-H6, thereby maximizing the recognition of B7-H6 tumor cells. By relying on the DuoBody technology, bispecific therapeutic antibodies were engineered, creating a panel of bispecific antibodies against NKp30xEGFR (cetuximab moiety) or NKp30xHER2 (trastuzumab moiety), called natural killer cell engagers (NKCEs).

The development of social attention in orangutans: Comparing peering behavior in wild and zoo-housed individuals.

Social learning plays an essential role in all cultural processes, but the factors underlying its evolution remain poorly understood. To understand how socio-ecological conditions affect social learning, we compared peering behavior (i.e.

The attraction effect of cleaning air on migrants in China: A comparative analysis with the contribution of wage and house prices.

Air pollution poses significant health risks and influences migration patterns, making it a global concern with widespread implications. Understanding its effects on where migrants choose to reside can provide insights for addressing environmental and social challenges. Matching micro-survey data of 1.

Yip1 interacting factor homolog B mediates the unconventional secretion of ORF8 during SARS-CoV-2 infection.

Severe cases of COVID-19 are associated with immune responses that lead to a surge in inflammatory molecules, resulting in multi-organ failure and death. This significant increase in inflammatory factors is triggered by viral proteins. Open reading frame 8 (ORF8) has received particular attention as a unique accessory protein of SARS-CoV-2.

Gene expression dynamics in fibroblasts during early-stage murine pancreatic carcinogenesis.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by aggressive growth and metastasis, partly driven by fibroblast-mediated stromal interactions. Using RNA sequencing of fibroblasts from early-stage KPC mouse models, we identified significant upregulation of genes involved in adipogenesis, fatty acid metabolism, and the ROS pathway. ANGPTL4, a key adipogenesis regulator, was highly expressed in fibroblasts and promoted pancreatic cancer cell proliferation and migration through paracrine signaling.

Relationships of eating behaviors with psychopathology, brain maturation and genetic risk for obesity in an adolescent cohort study.

Unhealthy eating, a risk factor for eating disorders (EDs) and obesity, often coexists with emotional and behavioral problems; however, the underlying neurobiological mechanisms are poorly understood. Analyzing data from the longitudinal IMAGEN adolescent cohort, we investigated associations between eating behaviors, genetic predispositions for high body mass index (BMI) using polygenic scores (PGSs), and trajectories (ages 14-23 years) of ED-related psychopathology and brain maturation. Clustering analyses at age 23 years ( = 996) identified 3 eating groups: restrictive, emotional/uncontrolled and healthy eaters.

Living with psychosis in West and Southeast Africa: SUCCEED Africa's four-country situation analysis.

As part of the formative work of the SUCCEED Africa consortium, we followed a participatory process to identify existing gaps and resources needed for the development and implementation of a rights-based intervention for people with lived experience of psychosis in Malawi, Nigeria, Sierra Leone and Zimbabwe. In 2021, we conducted a desk review of published and grey literature on psychosis in the four SUCCEED countries. Using an adapted version of the PRIME situation analysis template, data were extracted across the five domains of the WHO Community-Based Rehabilitation (CBR) Matrix: health, education, livelihoods, social and empowerment.

A response to criticism of the global mental health movement. How polarization can be overcome in theory and in west African social psychiatric practice.

Since the turn of the 21st century, we have seen the development of an international movement that works in various ways to ensure that everyone in the world has access to adequate mental health care. There is indeed a great need for action, especially in countries with weak and underfunded health systems. The Movement for Global Mental Health (MGMH) is supported by strong organizations such as the WHO, academic institutions and NGOs.

Hybrid hydrogels containing gradients in gold nanoparticles for localized delivery of mesenchymal stem cells and enhanced nerve tissues remodeling .

Currently, most peripheral nerve injuries are incurable mainly due to excessive reactive oxygen species (ROS) generation in inflammatory tissues, which can further exacerbate localized tissue injury and cause chronic diseases. Although promising for promoting nerve regeneration, stem cell therapy still suffers from abundant intrinsic limitations, mainly including excessive ROS in lesions and inefficient production of growth factors (GFs). Biomaterials that scavenge endogenous ROS and promote GFs secretion might overcome such limitations and thus are being increasingly investigated.

Cost-effectiveness of follow-up algorithms for chronic thromboembolic pulmonary hypertension in pulmonary embolism survivors.

Introduction: Achieving an early diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) in pulmonary embolism (PE) survivors results in better quality of life and survival. Importantly, dedicated follow-up strategies to achieve an earlier CTEPH diagnosis involve costs that were not explicitly incorporated in the models assessing their cost-effectiveness. We performed an economic evaluation of 11 distinct PE follow-up algorithms to determine which should be preferred.
