New neurons in old brains

The brain was traditionally viewed as a static organ, without turnover of neurons or significant capacity for self-repair after insults. Research in the last years has established that neurons are renewed in certain areas throughout life. The prospect of stimulation of endogenous neurogenesis as well as cell transplantation has raised hope for new therapies for neurological diseases.

Functional role and potential therapeutic use of Reelin, Gas6 and Protein S in relation to adult neural stem or progenitor cells

The invention relates generally to methods of influencing central nervous system cells to produce progeny useful in the treatment of CNS disorders. More specifically, the invention includes methods of exposing a patient suffering from such a disorder to a reagent that modulates the proliferation, migration, differentiation and survival of central nervous system cells via PACAP, Maxadilan or VIP si

Zinc as a modulator of transglutaminase activity - Laboratory and pathophysiological aspects

For a whole century, citrate has been used as an in vitro anticoagulant via chelation of calcium. Later, also EDTA was introduced as an anticoagulant. An often overlooked fact is that zinc is bound to citrate and EDTA with affinities much greater than that for calcium, imposing problems in biomedical research. In vivo, proteins of the S100 family are released from leukocytes and known to bind calc

Medical licensing examinations in both Sweden and the US favor pharmacology over lifestyle

Low priority of disease prevention and health promotion in medical education may contribute to lack of lifestyle-counseling in clinical practice. Pharmacology-related knowledge is valued 5 times higher compared to lifestyle-related knowledge in examinations on noncommunicable diseases (NCDs) in undergraduate medical education in Sweden. This study aims to establish (i) whether medical licensing ex

Early-life associations between per- and polyfluoroalkyl substances and serum lipids in a longitudinal birth cohort

Background: Exposures to per- and polyfluoroalkyl substances (PFASs) may affect metabolic outcomes, including lipid concentrations in the blood. However, few studies have evaluated potential associations between PFASs and lipids longitudinally. Objectives: We estimated associations between PFAS and lipid concentrations at birth and at several points in childhood. Methods: We measured concentration

Association of Mitochondrial DNA Copy Number and Telomere Length with Prevalent and Incident Cancer and Cancer Mortality in Women : A Prospective Swedish Population-Based Study

Changes in mitochondrial DNA copy number (mtDNA-CN) and telomere length have, separately, been proposed as risk factors for various cancer types. However, those results are conflicting. Here, mtDNA-CN and relative telomere length were measured in 3225 middle-aged women included in a large population-based prospective cohort. The baseline mtDNA-CN in patients with prevalent breast cancer was signif

Krisposeringarna - analys

Personer som deltar i en väpnad konflikt och som i samband med konflikten poserar på bild eller film intill stympade eller kränkta människokroppar kan lagföras för krigsförbrytelse i Sverige. Enligt Högsta domstolens avgörande 2021-05-05, mål nr B 5595-19. utgör en sådan handling en allvarlig kränkning av de dödas personliga värdighet som är straffbelagt med fängelse. Artikeln analyserar fallet.

Real-world effectiveness of vedolizumab in inflammatory bowel disease : week 52 results from the Swedish prospective multicentre SVEAH study

Background: Prospectively and systematically collected real-world data on vedolizumab are scarce. We aimed to assess the long-term clinical effectiveness of vedolizumab in inflammatory bowel disease (IBD). Methods: This study was a prospective, observational, multicentre study. Overall, 286 patients with active IBD were included (Crohn’s disease, n = 169; ulcerative colitis, n = 117). The primary

Experimental and Computational Models for Side Chain Discrimination in Peptide–Protein Interactions

A bis(18-crown-6) Tröger's base receptor and 4-substituted hepta-1,7-diyl bisammonium salt ligands have been used as a model system to study the interactions between non-polar side chains of peptides and an aromatic cavity of a protein. NMR titrations and NOESY/ROESY NMR spectroscopy were used to analyze the discrimination of the ligands by the receptor based on the substituent of the ligand, both

Integrating dissolved and particulate matter into a prediction tool for ozonation of organic micropollutants in wastewater

Ozonation is an established technique used to reduce the discharge of organic micropollutants into the aquatic environment, but the possibility of predicting the ozone demand for different wastewater matrices is still limited, especially in the presence of suspended solids (SS). A new tool for the prediction of the removal of organic micropollutants with ozone, based on dissolved and particulate m

How to advance theory through literature reviews in logistics and supply chain management

Purpose: The discipline's most common uses for literature reviews—identifying gaps, developing research agendas, and categorizing the literature—too often fail to challenge, change or advance theoretical perspectives. The authors offer guidance to theorization through literature reviews. The key to theory advancement is consistency between the state of theory and the chosen review type. Design/met

Cardiac Microvascular Disease Quantified with CMR

This thesis has investigated three different diagnoses where cardiac microvascular disease is suspected: hypertrophic cardiomyopathy (HCM), systemic sclerosis (SSc), and patients with suspected microvascular angina (MVA).Study I of this thesis investigated patients with HCM. We investigated the myocardial perfusion (MP) using cardiac magnetic resonance imaging (CMR) in young patients with HCM or t

Can B Corp certification anchor sustainability in SMEs?

B Corp certification is considered a viable instrument to support small and medium-sized enterprises (SMEs) in adopting sustainable practices. However, there is a lack of evidence to what extent this instrument can anchor sustainability at the core of SMEs. This study investigates the B Corp certification process of a SME, a craft brewery in southern Sweden, regarding the extent to which it helped

Selective oxidation of benzyl alcohols with molecular oxygen as the oxidant using Ag-Cu catalysts supported on polyoxometalates

We report an efficient process for the oxidation of benzyl alcohols using molecular oxygen as the oxidant catalyzed by Ag-Cu catalysts supported on polyoxometalates (Ag-Cu/POM). The Ag-Cu/POM catalyst was prepared by galvanic displacement in the presence of polyvinyl pyrrolidone and polyethylene glycol. The catalysts were characterized using Fourier transform infrared spectroscopy (FTIR), ultravio

A-Asterisk Algorithm as an Alternative to Evaluate the Geometric Tortuosity in Digitally Created SOFC Anodes

A solid oxide fuel cell (SOFC) contains complex materials that facilitate the energy conversion process. The diffusion media play an important role in facilitating the reactant gases to reach the electrochemical active regions. Porosity and tortuosity are crucial parameters describing the diffusion to be analyzed in a SOFC anode. This paper aims to evaluate the feasibility of using the A-asterisk

The Calendars of Southeast Asia : 6: Calendrical Records

Calendrical inscriptions and chronicles are an important source of information on the history and civilisation of Southeast Asia. Most of the records are horoscopes but there are also inscriptions commemorating the foundation of temples and other important buildings, and on Buddha images. Stone inscriptions are necessarily commemorative and the event celebrated is frequently of considerable social
