The PITX family of transcription factors regulate the development of many organs. Pitx1 mutants have a mild pituitary phenotype, but Pitx2 is necessary for the development of Rathke's pouch, expression of essential transcription factors in gonadotropes, and expansion of the Pit1 lineage. We report that lack of Pitx2 causes the pouch to undergo excessive cell death, resulting in severe pituitary hy
Metal halide perovskites are an important class of emerging semiconductors. Their charge carrier dynamics is poorly understood due to limited knowledge of defect physics and charge carrier recombination mechanisms. Nevertheless, classical ABC and Shockley-Read-Hall (SRH) models are ubiquitously applied to perovskites without considering their validity. Herein, an advanced technique mapping photolu
16 april 2026 08:00 till 18:00 | Workshop Curious about what microplastics and nanoplastic look like? Come and explore, count, and talk with us about this tiny, fascinating, yet alarming, world. We will look through microscopes and produce and manipulate art. Plastic pollution has become one of the most pressing environmental issues of our time, with micro- and nanoplastics emerging as a significa

In X-ray grating interferometry, dark-field contrast arises due to partial extinction of the detected interference fringes. This is also called visibility reduction and is attributed to small-angle scattering from unresolved structures in the imaged object. In recent years, analytical quantitative frameworks of dark-field contrast have been developed for highly diluted monodisperse microsphere sus
Fabrication and application of a non-fluorescent and UV-transparent microfluidic biochip in fused silica that allows sensitive autofluorescence detection are described. The biochip is particularly useful in cell-based assays where the most informative autofluorescence signals from the cells reside in the ultraviolet spectral range and where plastic labware materials commonly used in cell culture w
Therapeutic antibodies are transforming the treatment of cancer and autoimmune diseases. Today, a key challenge is finding antibodies against new targets. Phenotypic discovery promises to achieve this by enabling discovery of antibodies with therapeutic potential without specifying the molecular target a priori. Yet, deconvoluting the targets of phenotypically discovered antibodies remains a bottl
We present a novel, interferometric, two-color, high-order harmonic generation setup based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each interferometer arm contains a spatial light modulator with individual capabilities to manipulate the spatial beam profiles and to stabilize the relative delay between the fundamental and the second harmonic. In addition, sep
With increasing concerns about environmental impacts of the food that is consumed, so is also the concern about packaging materials. This also comprises the packaging that is currently used to pack infant formula (IF), very often containing aluminum as the barrier material. IF is a very sensitive product that demands for the highest barriers to protect it from lipid oxidation. This implies that th
Föreliggande undersökning syftar till att utvärdera möjligheten att använda bioimpedansspektrometri för att mäta tumör- och vävnadsrespons på strålterapi. Bioimpedansmätningar utförda med CythorLab ™ utrustade med en signalgenerator med en känd högutgångsimpedans och signalmätanordning som kan mäta spänningen som appliceras av generatorn. Styrenheten utlöser signalgeneratorn som genererar en MLS-sThe present investigation aims to evaluate the possibility of using bio-impedance spectrometry to measure tumour and tissue response to radiation therapy. Bio -impedance measurements performed with CythorLab™ equipped with a signal generator with a known high output impedance and signal measuring device able to measure the voltage applied by the generator. The control unit triggers the signal gene
Min uppstas syftar till att få reda på de argument som låg till grund för kriminaliseringen av sexuell tjänst som kom 1999 och varför endast köparen kriminaliserades. Min uppsats sträcker sig över en lång period från 1977-2011. Vad jag fann var att samhället i stort gick från en syn på att prostitution var ett problem för mannen, kvinnan och samhället i stort till att allt mer rikta in sig på att
Objective: Data remain divergent regarding the activational effects of endogenous hormones on adult cognitive function. We examined the association between cognition, hormones and androgen receptor (AR) CAG repeat length in a large cohort of men. Design: Community-based, cross-sectional study of 3369 men aged 40-79 years. Methods: Cognition tests were the Rey-Osterrieth Complex Figure, Camden Topo
There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each produc
20191022 Inresande forskningspraktikanter (grund- eller masterstudenter) Den internationella kommittén vid Institutionen för psykologi har beslutat om riktlinjer för att skapa bra förutsättningar för ett ömsesidigt givande forskningssamarbete mellan inkommande forskningspraktikanter samt ansvariga forskare. Då du som forskare blir kontaktad av internationella studenter som önskar delta i ett forsk
