BioMEL : a translational research biobank of melanocytic lesions and melanoma
Introduction Diagnosing invasive cutaneous melanoma (CM) can be challenging due to subjectivity in distinguishing equivocal nevi, melanoma in situ and thin CMs. The underlying molecular mechanisms of progression from nevus to melanoma must be better understood. Identifying biomarkers for treatment response, diagnostics and prognostics is crucial. Using biomedical data from biobanks and population-
Rise and fall of the giants? : Innovating firms in Sweden, 1890-2016
This study investigates patterns of innovation during two successive industrial revolutions in Sweden. “Genius engineering firms”, such as L M Ericsson, SKF and ASEA (ABB) have dominated narratives about Sweden’s industrial and innovation success. Using new long-term data series of innovation output, 1890-2016, we observe several patterns. First, we document inverted U-shaped patterns during the c
New Antidiabetic Agents for the Treatment of Heart Failure in Hypertensive Patients
The development of newer glucose-lowering drugs for the treatment of type 2 diabetes in recent years, such as the SGLT-2 inhibitors and GLP-1 receptor agonists/analogues with well-documented clinical benefits from large trials, has influenced international guidelines. These drugs are able to reduce both macro- and microvascular events in patients with type 2 diabetes and to prevent worsening of di

Chronic widespread pain and cause of death : a 25-year follow-up study
Introduction:Chronic widespread pain (CWP) has been suggested as a risk factor for mortality in cardiovascular diseases and malignancies. Different definition of CWP makes it difficult to compare previous studies.Objectives:The aim was to study whether mortality and certain causes of death were increased among people with CWP and whether the definition of CWP influenced outcome.Methods:This 25-yea
Germination and stress tolerance of oats treated with pulsed electric field at different phases of seedling growth
This study explores the impact of pulsed electric field (PEF) application on oat seedling growth and stress tolerance. PEF treatment (99 monopolar, rectangular pulses lasting 10 µs each, with a frequency of 13 Hz and a nominal electric field strength of 2250 V/cm) was applied at two growth stages: (i) when the seedlings had 0.2 cm roots emerging from the kernel, and (ii) when they had a 0.4 cm sho
High cell density sequential batch fermentation for enhanced propionic acid production from glucose and glycerol/glucose mixture using Acidipropionibacterium acidipropionici
Background: Propionic acid fermentation from renewable feedstock suffers from low volumetric productivity and final product concentration, which limits the industrial feasibility of the microbial route. High cell density fermentation techniques overcome these limitations. Here, propionic acid (PA) production from glucose and a crude glycerol/glucose mixture was evaluated using Acidipropionibacteri
Proteomic analysis of Parkinson’s disease mechanism and biomarkers
Synthesis of Homo- and Copolyesters Using an AB-Type Aromatic Monomer Based on Homovanillic Acid
There is currently intensive research ongoing with the aim to utilize various lignin-derived molecules to produce aromatic monomers and polymers. In the present work, homovanillic acid (HVA), derived from lignin, was used to prepare sustainable polyesters for the first time. An AB-type monomer with an alcohol group and a carboxylate ester group was conveniently synthesized by using HVA and et
T-cell commitment inheritance—an agent-based multi-scale model
T-cell development provides an excellent model system for studying lineage commitment from a multipotent progenitor. The intrathymic development process has been thoroughly studied. The molecular circuitry controlling it has been dissected and the necessary steps like programmed shut off of progenitor genes and T-cell genes upregulation have been revealed. However, the exact timing between decisio
Transport and retention of functionalized graphene oxide nanoparticles in saturated/unsaturated porous media : Effects of flow velocity, ionic strength and initial particle concentration
The widespread use of nanomaterials has raised the threat of nanoparticles (NPs) infection of soils and groundwater resources. This research aims to investigate three parameters including flow velocity, ionic strength (IS), and initial particle concentration effects on transport behavior and retention mechanism of functionalization form of graphene oxide with polyvinylpyrrolidone (GO-PVP). The tra
3D non-LTE modeling of the stellar center-To-limb variation for transmission spectroscopy studies
Context. Transmission spectroscopy is one of the most powerful techniques used to characterize transiting exoplanets, since it allows for the abundance of the atomic and molecular species in the planetary atmosphere to be measured. However, stellar lines may bias the determination of such abundances if their center-To-limb variations (CLVs) are not properly accounted for. Aims. This paper aims to
EDGE – Dark matter or astrophysics? Breaking dark matter heating degeneracies with H I rotation in faint dwarf galaxies
Low-mass dwarf galaxies are expected to reside within dark matter haloes that have a pristine, ‘cuspy’ density profile within their stellar half-light radii. This is because they form too few stars to significantly drive dark matter heating through supernova-driven outflows. Here, we study such simulated faint systems (104 ≤ M* ≤ 2 × 106 M) drawn from high-resolution (3 pc) cosmological simulation
Integrative Kinase Activity Profiling and Phosphoproteomics of rd10 Mouse Retina during cGMP-Dependent Retinal Degeneration
Inherited retinal degenerative diseases (IRDs) are a group of rare diseases that lead to a progressive loss of photoreceptor cells and, ultimately, blindness. The overactivation of cGMP-dependent protein kinase G (PKG), one of the key effectors of cGMP-signaling, was previously found to be involved in photoreceptor cell death and was studied in murine IRD models to elucidate the pathophysiology of
Analysis of vitamin D and its metabolites in biological samples – Part II : Optimization of a sample preparation method for liver tissue
Extraction of vitamin D, including its hydroxylated and esterified metabolites, from soft tissues such as the liver is challenging due to the lipophilic character of matrix and analytes that are expected in very low concentration levels. In this study, we aimed at the optimization of two-step extraction using solid–liquid extraction as the first step, followed by solid-phase extraction. Various so
Kidney dosimetry in [177Lu]Lu-DOTA-TATE therapy based on multiple small VOIs
Purpose: The aim was to investigate the use of multiple small VOIs for kidney dosimetry in [177Lu]Lu-DOTA-TATE therapy. Method: The study was based on patient and simulated SPECT images in anthropomorphic geometries. Images were reconstructed using two reconstruction programs (local LundaDose and commercial Hermia) using OS-EM with and without resolution recovery (RR). Five small VOIs were placed
Food Safety 4.0
Food Safety 4.0 is a term derived from Industry 4.0 that focuses on all aspects of food safety management based on cyber-physical systems. The premise of Food Safety 4.0 is that real-time information and the interconnectivity of things, complemented by novel technologies, will revolutionize the way food safety is managed. There is enormous potential in terms of advancing product traceability, dete
High Oestrogen receptor alpha expression correlates with adverse prognosis and promotes metastasis in colorectal cancer
In normal colon tissue, oestrogen receptor alpha (ERα) is expressed at low levels, while oestrogen receptor beta (ERβ) is considered the dominant subtype. However, in colon carcinomas, the ERα/β ratio is often increased, an observation that prompted us to further investigate ERα’s role in colorectal cancer (CRC). Here, we assessed ERα nuclear expression in 351 CRC patients. Among them, 119 exhibit
Analysis of vitamin D and its metabolites in biological samples – Part I : Optimization and comparison of UHPSFC-MS/MS and UHPLC-MS/MS methods
Fat-soluble vitamin D is an essential bioactive compound important for human health. Insufficient vitamin D levels can result not only in bone disease but also in other disorders, such as cancer, metabolic disorders, and diseases related to poor immune function. The current methods commonly used for vitamin D analysis are often applied to determine the levels of the most abundant metabolite in pla
