Steroid transformation by activated living immobilized Arthrobacter simplex cells

A preparation of living Arthrobacter simplex cells immobilized in polyacrylamide gel, which showed steroid-Δ1-dehydrogenase activity, was studied. The entrapped microorganisms catalyzed the transformation of cortisol to prednisolone and this reaction was followed spectrophotometrically or with the aid of thin layer chromatography (TLC) and high pressure liquid chromatography (HPLC). About 40% of t

Machine learning-derived phenotypic trajectories of asthma and allergy in children and adolescents : protocol for a systematic review

INTRODUCTION: Development of asthma and allergies in childhood/adolescence commonly follows a sequential progression termed the 'atopic march'. Recent reports indicate, however, that these diseases are composed of multiple distinct phenotypes, with possibly differential trajectories. We aim to synthesise the current literature in the field of machine learning-based trajectory studies of asthma/all

The recent World Health Organization (WHO) guideline aims to provide evidence-based recommendations on complementary feeding (CF) of healthy term infants and young children 6−23 months living in low-, middle-, and high-income countries, including both breastfed and non-breastfed children. Like WHO, our organizations aim to promote optimal infant and young child nutrition and health, with a focus o

Preparation of an Active Soluble Lactate Dehydrogenase-Nicotinamide Adenine Dinucleotide Complex Using Glutaraldehyde

The cofactor analogue N6-((6-aminohexyl)-carbamoylmethyl)-NAD was bound to beef heart lactate dehydrogenase by the glutaraldehyde coupling method and the enzyme-coenzyme complex subsequently separated from excess of non-coupled cofactor by gel filtration chromatography. The number of cofactor molecules bound per enzyme molecule could be varied between 0 and 8 by altering the coupling time. The enz

Uppmaningens realisering i en idrottspedagogisk kontext

This dissertation investigates the Swedish directive speech act in spoken language, focusing on directives used to prompt actions. Directives can be direct, like imperatives, or more polite, embedded in structures typically associated with other speech acts, such as interrogative or declarative forms. The study centers on Physical Education and Health (PEH) lessons, where directives are prevalent.This dissertation investigates the Swedish directive speech act in spoken language, focusing on directives used to prompt actions.

Synthesis of the bifuncttonal dinucleotide AMP-ATP and its application in general ligand affinity chromatography

A new AMP derivative substituted with spacer arms both at position N6 and C8 of the adenine moiety was synthesized and immobilized to Sepharose. To the immobilized ligand was subsequently coupled C8-substituted ATP in a solid-phase synthesis fashion yielding the bifunctional general ligand AMP-ATP. This affinity material was used in the separation of two major groups of enzymes, dehydrogenases and

AbstractIn Sweden, the notion of gender identity is up for renegotiation and an increasing number of people are seeking professional support in relation to these issues. Professionals dealing with gender issues are either the transgender health care, specialized in transgender issues, or general practitioners.The purpose of the study is to investigate professional work with people who are question

Fallstudie av ett BREEAm-projekt

I takt med ett ökat klimatarbete och ambitioner på EU-nivå i from av EU:s taxonomi, har bygg- och anläggningssektorn tagit fram en färdplan gällande omställningen för att nå nettonollutsälpp senast 2045. Som en del av utvecklingen presenterar Swedish Green Building Council att miljöcertifieringar säkerställer hållbara byggnader, vilket även stöds av tidigare forskning. Utmaningen med miljöcertifieThis study has investigated the incentives for obtaining BREEAM certification for a building. The study focused on a case of BREEAM certification at the Excellent level and compared it with the lowest energy requirements in Sweden from an energy, cost, and climate perspective. The reference object for the study is a building, soon to be finished, in Linköping Sweden intended for healthcare and res

Understanding the genetic complexity of puberty timing across the allele frequency spectrum

Pubertal timing varies considerably and is associated with later health outcomes. We performed multi-ancestry genetic analyses on ~800,000 women, identifying 1,080 signals for age at menarche. Collectively, these explained 11% of trait variance in an independent sample. Women at the top and bottom 1% of polygenic risk exhibited ~11 and ~14-fold higher risks of delayed and precocious puberty, respe

Outcomes of Cytoreductive Radical Prostatectomy for Oligometastatic Prostate Cancer on Prostate-specific Membrane Antigen Positron Emission Tomography : Results of a Multicenter European Study

BACKGROUND: De novo oligometastatic prostate cancer (omPCa) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) is a new disease entity and its optimal management remains unknown. OBJECTIVE: To analyze the outcomes of patients treated with cytoreductive radical prostatectomy (cRP) for omPCa on PSMA-PET. DESIGN, SETTING, AND PARTICIPANTS: Overall, 116 patients treated wi

Interplay between glypican-1, amyloid-β and tau phosphorylation in human neural stem cells

Introduction: Alzheimer's disease (AD) is characterized by accumulation of amyloid beta (Aβ) and hyperphosphorylated tau (Tau-P) in the brain. Aβ enhances the activity of kinases involved in the formation of Tau-P. Phosphorylation at Thr 181 determines the propagation of multiple tau phosphorylations. Aβ is derived from the amyloid precursor protein (APP). Cleavage of APP by β-secretase also initi

A comparative assessment of five precipitation products in the Saharan desert of Morocco : Sakia El Hamra basin case study

This study evaluates the performance of five satellite precipitation products (GPM IMERG, TRMM 3B42, ERA5, PERSIANN, and CHIRPS) compared to monthly observations from two weather stations (Laayoune and Essmara) over 2001–2017 using statistical metrics including correlation coefficient (CC) and mean square error (MSE). The results reveal notable differences between products. On a monthly timescale,

From ice-dammed lake to aeolian dunes in the Store Mosse area, SW Sweden

Wind is a significant geomorphological agent in formerly glaciated areas and aeolian deposits surround and stretch across the Store Mosse (Great Bog) bog complex in southwestern Sweden. Both peat and aeolian sand are underlain by lacustrine sediment and the deposits record the area's transition from an initially ice-dammed lake to Ancient Lake Bolmen, which gradually drained, exposing sediments to

Brazil has faced severe droughts in recent decades, significantly affecting agriculture, water supply, and hydropower generation, among other sectors. The Paraná River Basin, a major hub for hydropower, has been particularly affected, posing challenges for water management. To address this, we conducted a study to provide tailored climate information for the Brazilian hydroelectric sector. Given t

Total mesorectal excision quality in rectal cancer surgery affects local recurrence rate but not distant recurrence and survival : population-based cohort study

Background: The quality of the total mesorectal excision specimen in rectal cancer surgery is assessed with a three-tier grade (mesorectal, intramesorectal and muscularis propria). This study aimed to analyse the prognostic impact of the total mesorectal excision grade on survival, and to identify risk factors for intramesorectal and muscularis propria resection in a population-based setting. Meth

Meta-analytical evidence for frequency-dependent selection across the tree of life

Explaining the maintenance of genetic variation in fitness-related traits within populations is a fundamental challenge in ecology and evolutionary biology. Frequency-dependent selection (FDS) is one mechanism that can maintain such variation, especially when selection favours rare variants (negative FDS). However, our general knowledge about the occurrence of FDS, its strength and direction remai

Melanoma Incidence and Mortality Trends in Sweden

IMPORTANCE: Over the past decades, many global regions have experienced a steady increase in the incidence of cutaneous melanoma. However, more recently, a downward trend has been observed in the younger age groups in Australia and the US. Yet, in Europe, none of the countries have reported any significant decline in melanoma incidence for any age group.OBJECTIVE: To assess melanoma incidence and

Interobserver agreement on line-field confocal optical coherence tomography image markers in keratinocyte carcinomas and precursor lesions

Line-field confocal optical coherence tomography (LC-OCT) is a new technology for skin cancer diagnostics. However, the interobserver agreement (IOA) of known image markers of keratinocyte carcinomas (KC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), as well as precursors, SCC in situ (CIS) and actinic keratosis (AK), remains unexplored. This study determined IOA on the
