Azoospermia is a serious potential side effect following treatment for testicular cancer (TC). Our purpose was to examine possible predictors of long-term azoospermia in TC survivors. Ejaculates and blood samples were obtained from 217 patients at post-orchidectomy but before further treatment (T0 ) and/or at one or more of the time points 6, 12, 24, 36-60 months after treatment (T6 , T12 , T24 ,

In hybrid zones populations that are otherwise allopatric meet and produce hybrids. One of the most well-known hybrid zones occurs throughout much of Europe between the hooded and carrion crows. Even though these species (or subspecies) of crows look very different, genetic differentiation is weak, and introgression seems to be common. In a spatial simulation that was based on empirically estimate

Background No effective standard treatment exists for patients with radioiodine-refractory, advanced differentiated thyroid carcinoma. We aimed to assess efficacy and safety of vandetanib, a tyrosine kinase inhibitor of RET, VEGFR and EGFR signalling, in this setting. Methods In this randomised, double-blind, phase 2 trial, we enrolled adults (aged >= 18 years) with locally advanced or metastatic

BACKGROUND: Randomized controlled trials relatively consistently show that restrictive red blood cell (RBC) transfusion strategies are safe and associated with similar outcomes compared to liberal transfusion strategies in critically ill patients. Based on these data, the general threshold for RBC transfusion was changed to 70 g/L at a 9-bed tertiary level intensive care unit in September 2020. Im

BACKGROUND: Lactiplantibacillus plantarum HEAL9 and Lacticaseibacillus paracasei 8700:2 positively affect the fecal bacteriome in children with celiac disease autoimmunity after 6 months of supplementation. The aim of the present investigation was to study the effects of Lactiplantibacillus plantarum HEAL9 and Lacticaseibacillus paracasei 8700:2 on the single-cell parasitome, with a primary focus

Background: Sports function and psychological readiness to return to sports (RTS) are important outcomes when evaluating rehabilitation after anterior cruciate ligament reconstruction (ACLR). It is, however, unclear which specific factors contribute most to these outcomes. Purpose: To determine associations between demographic characteristics, objective measurements of physical function, patient-r

IMPORTANCE: The introduction of solid or semisolid foods alongside breast milk plays a vital role in meeting nutritional requirements during early childhood, which is crucial for child growth and development. Understanding the prevalence of zero-food children (defined for research purposes as children aged 6 to 23 months who did not consume animal milk, formula, or solid or semisolid food during t

Objective: The heterogeneity of systemic lupus erythematosus (SLE) constitutes clinical and therapeutical challenges. We therefore studied whether unrecognized disease subgroups can be identified by using autoantibody profiling together with HLA-DRB1 alleles and immunological and clinical data. Methods: An unsupervised cluster analysis was performed based on detection of 13 SLE-associated autoanti

Background and ObjectivesIdentifying a clinically meaningful change in cognitive test score is essential when using cognition as an outcome in clinical trials. This is especially relevant because clinical trials increasingly feature novel composites of cognitive tests. Our primary objective was to establish minimal clinically important differences (MCIDs) for commonly used cognitive tests, using a

The aim of this study was to perform a preliminary assessment of the expected effective dose rate from external exposure to an adult individual staying at that part of the radioactively contaminated territory of the Vetka district of the Gomel region of the Republic of Belarus, from where residents had been resettled after the Chernobyl accident. For this assessment, in summer 2016 and 2018 soil s

Objective: To explore experiences with supervised group exercise during pregnancy in women with depression or low psychological well-being. Design: A qualitative descriptive study based on semi-structured, individual, in-depth interviews analyzed by means of thematic analysis. Setting: The Department of Obstetrics, Rigshospitalet, Copenhagen University Hospital, Denmark. Participants: Through a pu

Solid organ transplant recipients (SOTRs) are on lifelong immunosuppression, which may interfere with adaptive immunity to COVID-19. The data on dynamics and duration of antibody response in SOTRs are limited. This longitudinal study examined the longevity of both anti-spike (S)- and anti-nucleocapsid (N)-specific IgG antibodies after COVID-19 in SOTRs compared to matched immunocompetent persons.

Background: The carba mix is used to screen rubber chemical allergy and consists of three rubber sensitising chemicals: 1% (w/w) zinc diethyldithiocarbamate (ZDEC), 1% (w/w) zinc dibutyldithiocarbamate (ZDBC) and 1% (w/w) 1,3-diphenylguanidine (DPG), all in petrolatum. However, carba mix patch test results can be difficult to interpret, which may be linked to so-called ‘cocktail’ effects. Objectiv

Katalysatorer påskyndar en reaktion utan att själva förbrukas; denna mening känner nog många igen från sin skoltid. Andra har hört talas om katalysatorer som något de "har i bilen". Mycket riktigt är det främst i bilar där vi i våra vardagliga liv stöter på katalysatorer. Här används de för att omvandla de mycket giftiga gaserna kolmonoxid och kväveoxid till för människorna ofarligt kvävIn order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase

Sverige är sedan 1971 ansluten till FN-konventionen om avskaffande av alla former av rasdiskriminering. Konventionen tillkom som en reaktion mot rasdiskriminerande förtryck i form av apartheid och kolonialism. Varje konventionsstat är enligt konventionens art. 4(b) skyldig att olagligförklara och förbjuda organisationer som främjar och uppmanar till rasdiskriminering. Trots upprepad kritik från In 1971, Sweden ratified the United Nations convention on the elimination of all forms of racial discrimination. It was established as a reaction to racial oppression, such as apartheid and colonialism. All state parties are, under article 4, obliged to prohibit and criminalise organisations who in any way promote or encourage racial discrimination. Sweden has, in spite of criticism from the conve

The app-industry today is ruled by two giants, namely Android and iOS. For companies and developers, it is essential to deliver their product to the majority of users, thus adapting to both platforms. The platforms involve their own way of developing applications and only barely resembles each other. A problem that the industry faces resides here, having to hire staff with knowledge in either Andr

Mammalian cells are frequently under stress leading to DNA damage because of UV exposure, ionizing radiation or genotoxic chemicals. Cells have evolved a DNA damage response (DDR) mechanism to ensure survival and pass on the correct genetic information to the next generation. MITF is a melanocyte-specific transcription factor. It has been shown to accumulate in the vicinity of DNA damage and its e

This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes

Popular science This study describes the development and implementation of a Photo Voltaic (PV)Roof Integration Analysis Tool integrated into a GIS system in order to be used in conducting research within alternative energy field. This study focuses on the Dokki district in Greater Cairo that was used as a case for developing the idea of a tool to assess the possibility of the roofs of existing bu

In a recent experiment, the partial half-life (t1/2) of proton emission from the Iπ = 19/2- state of 53Co was accurately measured. A previous estimate is t1/2 ~ 17 s. The purpose of this thesis was to explain this decay and give a theoretical estimate for the dominating hindrance factors. The angular momentum J in 53Co is coupled to J = 6 for the neutrons, and J = 7/2 for the protons. All of this
