STUDY QUESTION Which spermatogonial differentiation states are present in prepubertal testes under normal conditions and following chemotherapy-induced depletion of spermatogonia in paediatric patients with cancer? SUMMARY ANSWER Single-cell transcriptomic analysis reveals that only undifferentiated spermatogonia are present in prepubertal boys, while differentiated states emerge during puberty, w

In both second language acquisition research and teaching, there is a need for practical, reliable and valid proficiency tests to be used with learners of various target languages and at different proficiency levels. In the present study, a written proficiency test based on the C-test methodology was developed and tested on 144 Swedish 15-year-olds studying French, German, and Spanish in lower sec

Rechargeable magnesium batteries could provide future energy storage systems with high energy density. One remaining challenge is the development of electrolytes compatible with the negative Mg electrode, enabling uniform plating and stripping with high Coulombic efficiencies. Often improvements are hindered by a lack of fundamental understanding of processes occurring during cycling, as well as t

We study two-dimensional, stationary square and hexagonal patterns in the thermocapillary deformational thin-film model for the fluid height h [Formula presented] that can be formally derived from the Bénard–Marangoni problem via a long-wave approximation. Using a linear stability analysis, we show that the flat surface profile corresponding to the pure conduction state destabilises at a critical

Brain organoid technology has seen significant development in recent years. This self-organized, three-dimensional, organ-oriented brain tissue model can recapitulate the process of neurogenesis and consists of diverse cell types and cellular architecture. Transplanting brain organoids in vivo could be a potential tool from bench to clinical research and has been studied for many purposes. To inve

BACKGROUND: The implementation of COVID-19 vaccination among older persons at nursing homes has lowered the infection-associated mortality considerably, but emerging virus variants and decline in vaccine-induced immunity over time necessitate examination of future booster dosing strategies. The overall aim of this study was to assess vaccine protection against COVID-19 mortality in relation to tim

Canada has a long history of colonialism that ended in 1867. Before and after this the Indigenous peoples have been the target of several assimilation strategies, the most famous being the Indian Residential Schools system. To deal with its legacy, the Truth and Reconciliation Commission of Canada was set up. Critique has been directed towards the commission for failing to deal with unequal power

Findings about the relationship between climate change and conflict has, since research on the topic started in the late 1990s, been inconclusive. A more recent statistical study has however concluded that drought might prolong conflict under certain conditions. To further our understanding of this relationship, this single-N case study has investigated these recent findings on an extreme case, wh

This paper explores home bias and the performance of exchange traded funds (ETFs) and bonds under the context of Environmental, Social and Governance (ESG). It analyzes investment strategies led by non-financial variables such as sustainable and responsible investment and how it affects the expected returns and risk and if the home bias phenomenon is weaker when following the said strategy. The

When they migrate to another Member State (MS), EU citizens must adjust to a country whose legal environment is composed of both national laws and EU laws. Additionally, mobile EU citizens have their own legal culture which crafts the way they make sense of mundane circumstances and social interactions. What comes out of the mutual interplay between the host MS’s legal environment and mobile EU ci

Covid19 pandemin har inneburit stora utmaningar för psykisk hälsa globalt, dels på grund av begränsningar som införts för att minska smittspridningen såsom social distansering, men också rädslan som följer att leva under oroliga tider. Tidigare studier har bidragit till förklaringar av covid19’s effekter på psykisk hälsa genom att fokusera på antingen personlighetsbaserade eller kontextuella faktoThe covid19 pandemic has presented great challenges to mental health globally, in part due to restrictions implemented in the wake of the pandemic; such as social distancing, but also due to the fear and psychological distress associated with living during times of crisis. Prior studies have contributed to explaining covid19’s effects on mental health by addressing either personality-based or cont

The purpose of this paper is to shed light on museum visitors’ experiences during the pandemic. Precisely, we aim to investigate visitors’ expectations and experiences towards digital channels and identify potential gaps between museums’ offering and what visitors’ are looking for, further providing insights on the perceived advantages and limitations of museums’ digital transformation. The rese

In a global social divide between modern and traditional, medicine has fallen into two sides. Still, much of modern medicine exists because of traditional medicinal knowledge, yet the latter is rarely given any recognition. Despite increasing juridical attempts to protect indigenous groups and their traditional knowledge from biopiracy, the issue remains prevalent. Therefore, this thesis looks at

This paper investigates the effects of behavioral finances on stock market participation by employing data from China Family Panel Study (CFPS). Availability and trust are chosen as the target variables to explain the participation problems in the stock market. The study finds evidence that financial service availability and individual trust have positive influences on the stock market participati

Abstract This thesis investigates the impacts pre-merger characteristics play in long-term post-merger performance from a sample of small and medium sized enterprises whom conducted M&A activity within the European Union between the time period of 2011-2013. Using data collected, a quantitative analysis was performed to measure the impact of six separate factors on post-merger performance anal
