Age-related pathological impairments in directly reprogrammed dopaminergic neurons derived from patients with idiopathic Parkinson's disease

We have developed an efficient approach to generate functional induced dopaminergic (DA) neurons from adult human dermal fibroblasts. When performing DA neuronal conversion of patient fibroblasts with idiopathic Parkinson's disease (PD), we could specifically detect disease-relevant pathology in these cells. We show that the patient-derived neurons maintain age-related properties of the donor and

Repeat Dynamics across Timescales : A Perspective from Sibling Allotetraploid Marsh Orchids (Dactylorhiza majalis s.l.)

To provide insights into the fate of transposable elements (TEs) across timescales in a post-polyploidization context, we comparatively investigate five sibling Dactylorhiza allotetraploids (Orchidaceae) formed independently and sequentially between 500 and 100K generations ago by unidirectional hybridization between diploids D. fuchsii and D. incarnata. Our results first reveal that the paternal

Astrocytic function is associated with both amyloid-β and tau pathology in non-demented APOE 4 carriers

A growing body of evidence suggests that astrocytes play a major role in the pathophysiology of Alzheimer's disease. Given that APOE is primarily expressed in astrocytes, these cells might be an important link between the APOE ϵ4 allele and the development of Alzheimer's disease pathology. Here, we investigate this hypothesis in vivo by measuring myo-inositol, a metabolite involved in astrocytic f

Heat exchanger network optimisation considering different shell-side flow arrangements

Heat exchanger network synthesis (HENS) is an effective tool for heat recovery in chemical and petrochemical industries. This study aims to show a method for HENS with the consideration of different shell-side flow arrangements in shell-and-tube heat exchangers. The proposed MINLP model is modified from the stage-wise superstructure model, incorporating newly developed correlations for shell-side

Locked in unsustainability : Understanding lock-ins and their interactions using the case of food packaging

Lock-in mechanisms are major hurdles to sustainability transitions. Scholars identified various types of lock-ins; however, their dynamics and interactions remain underexplored. Using the case of food packaging, this study enhances the conceptual understanding and empirical analysis of lock-ins and their interactions from a socio-technical perspective. We analyze the material, institutional, behav

Increased plasma and brain immunoglobulin A in Alzheimer’s disease is lost in apolipoprotein E ε4 carriers

Background: Alzheimer’s disease (AD) is foremost characterized by β-amyloid (Aβ)-extracellular plaques, tau-intraneuronal fibrillary tangles (NFT), and neuroinflammation, but over the last years it has become evident that peripheral inflammation might also contribute to the disease. AD patients often demonstrate increased levels of circulating proinflammatory mediators and altered antibody levels

Design and implementation of tailored intervention to increase vaccine acceptance in a Somali community in Stockholm, Sweden - based on the Tailoring Immunization Programmes approach

Objectives: Sweden has had a high and stable vaccination coverage for measles-mumps-rubella (MMR) vaccine (>96%) through the national immunization program (NIP), but coverage rates highlight local pockets of lower vaccination coverage. This project addressed low MMR vaccine acceptance among parents in a Somali community, in Stockholm. The objective of the intervention was to increase vaccine confi

Hand function 6 weeks following non-surgically treated proximal phalangeal fractures and factors associated to upper extremity disability

Purpose: To describe hand function, and investigate adherence to a rehabilitation protocol and factors associated with upper extremity disability in non-surgically treated proximal phalangeal fractures. Material and methods: In a prospective cohort study, 86 patients (58 women, mean age of 49 years) were assessed at cast removal and 6 weeks follow-up. Adherence was registered in a diary. Factors p

A Recombinant Alpha-Like Protein Subunit Vaccine (GBS-NN) Provides Protection in Murine Models of Group B Streptococcus Infection

BACKGROUND: Group B Streptococcus (GBS) transmission during pregnancy causes preterm labor, stillbirths, fetal injury, or neonatal infections. Rates of adult infections are also rising. The GBS-NN vaccine, engineered by fusing N-terminal domains of GBS Alpha C and Rib proteins, is safe in healthy, nonpregnant women, but further assessment is needed for use during pregnancy. Here, we tested GBS-NN

Terahertz Spectroscopic Analysis of Lactose in Infant Formula : Implications for Detection and Quantification

Lactose plays a significant role in daily lives as a constituent of various food and pharmaceutical products. Yet, lactose intolerance conditions demand low-lactose and lactose-free products in the market. These increasing nutritional claims and labels on food products entail simple and reliable methods of analysis that can be used for meeting quality standards, nutritional claims and legal requir

Performance improvement of proton exchange membrane fuel cells with wavy flow channels : An experimental study

The gas flow field design plays a vital role in the cell performance of proton exchange membrane fuel cells, especially at high current densities. In this study, wavy flow channels are designed and adopted on the cathode side to enhance the mass transport process. Results demonstrate that the wavy flow channels proposed in this paper significantly improve cell performance at high current densities

Allometric scaling of a superposition eye optimizes sensitivity and acuity in large and small hawkmoths

Animals vary widely in body size within and across species. This has consequences for the function of organs and body parts in both large and small individuals. How these scale, in relation to body size, reveals evolutionary investment strategies, often resulting in trade-offs between functions. Eyes exemplify these trade-offs, as they are limited by their absolute size in two key performance feat

Cognitive Behavioral Therapy and Acceptance and Commitment Therapy (CBT-ACT) vs. Standard Care After Critical Illness Due to COVID-19 : Protocol for a Pilot Randomized Controlled Trial

Background: Post-covid syndrome is an emerging condition involving a wide range of symptoms, including high rates of poor mental health. The diagnostic relevance and clinical severity of these symptoms are largely unknown, and evidence for treatment of post-covid mental health symptoms is lacking. This protocol describes a pilot randomized clinical trial, primarily aiming to assess feasibility, pa

Association of thyroid function with blood pressure and cardiovascular disease : A mendelian randomization

Thyroid function has a widespread effect on the cardiometabolic system. However, the causal association between either subclinical hyper-or hypothyroidism and the thyroid hormones with blood pressure (BP) and cardiovascular diseases (CVD) is not clear. We aim to investigate this in a two-sample Mendelian randomization (MR) study. Single nucleotide polymorphisms (SNPs) associated with thyroid-stimu

CD244 expression represents functional decline of murine hematopoietic stem cells after in vitro culture

Isolation of long-term hematopoietic stem cell (HSC) is possible by utilizing flow cytometry with multiple cell surface markers. However, those cell surface phenotypes do not represent functional HSCs after in vitro culture. Here we show that cultured HSCs express mast cell-related genes including Cd244. After in vitro culture, phenotypic HSCs were divided into CD244- and CD244+ subpopulations, an

Rationale and design of the “NEurodegeneration : Traumatic brain injury as Origin of the Neuropathology (NEwTON)” study: a prospective cohort study of individuals at risk for chronic traumatic encephalopathy

Background: Repetitive head injury in contact sports is associated with cognitive, neurobehavioral, and motor impairments and linked to a unique neurodegenerative disorder: chronic traumatic encephalopathy (CTE). As the clinical presentation is variable, risk factors are heterogeneous, and diagnostic biomarkers are not yet established, the diagnostic process of CTE remains a challenge. The general
