Deep learning has allowed for remarkable progress in many medical scenarios. Deep learning prediction models often require 105–107 examples. It is currently unknown whether deep learning can also enhance predictions of symptoms post-stroke in real-world samples of stroke patients that are often several magnitudes smaller. Such stroke outcome predictions however could be particularly instrumental i
Student evaluation of teaching (SeT) is ubiquitous in higher education but has been criticized by many scholars because of low use for course improvement benefiting student learning. Academic developers (ADs) are responsible for pedagogical courses and to support leadership and academics in processes enhancing educational quality. We could therefore expect ADs to play a key role in SeT practice. T
Aim: In neuroendocrine cells, large dense-core vesicles (LDCVs) undergo highly regulated pre-fusion processes before releasing hormones via membrane fusion. Significant heterogeneity has been found for LDCV population based on the dynamics of membrane fusion. However, how the pre-fusion status impacts the heterogeneity of LDCVs still remains unclear. Hence, we explored pre-fusion determinants of h
The effective conversion of carbon dioxide (CO2) into valuable chemical fuels relies significantly on the donation of multiple electrons. Its efficiency is closely linked to both the density and lifetime of excited charge carriers. In this study, a hybrid catalyst system comprising covalently bonded InP/ZnS quantum dots (QDs) and Re-complexes is showcased. The electronic band alignment between the
IMPORTANCE: For individuals without a family history of colorectal cancer (CRC), colonoscopy screening every 10 years is recommended to reduce CRC incidence and mortality. However, debate exists about whether and for how long this 10-year interval could be safely expanded.OBJECTIVE: To assess how many years after a first colonoscopy with findings negative for CRC a second colonoscopy can be perfor
Various less-toxic substitutes for the Pb2+-based perovskites have been proposed, of which Sn2+-based metal halide perovskites (namely, Sn-PVSKs) hold the best prospects because of their optoelectronic properties comparable to those of the Pb analogues. Nevertheless, the intrinsic instability and unfavorable crystallization of Sn-PVSKs place restrictions on both the device performance/durability a
In the Western world, gender/sex is traditionally viewed as binary, with people falling into one of two categories: male or female. This view of gender/sex has started to change, triggering some resistance. This research investigates psychological mechanisms underlying that resistance. Study 1 (N = 489, UK) explored the role of individual gender identification in defense of, and attempts to reinfo
Background: The neural crest is a transient embryonic stem cell population. Hypoxia inducible factor (HIF)-2α is associated with neural crest stem cell appearance and aggressiveness in tumors. However, little is known about its role in normal neural crest development. Results: Here, we show that HIF-2α is expressed in trunk neural crest cells of human, murine, and avian embryos. Knockdown as well
Numerous biological mechanisms contribute to outcome after stroke, including brain injury, inflammation, and repair mechanisms. Clinical genetic studies have the potential to discover biological mechanisms affecting stroke recovery in humans and identify intervention targets. Large sample sizes are needed to detect commonly occurring genetic variations related to stroke brain injury and recovery.
Ulnar nerve compression at the elbow (UNE) frequently affects people of working age. Surgically treated patients may not immediately return to work (RTW) postoperatively. In 2008, the Swedish Social Insurance Agency reformed the national insurance policy. We aimed to examine RTW postoperatively for UNE, variations among surgical methods, and potential risk factors for prolonged RTW (sick leave > 6
Background and Objective: Waste in clinical trials remains rife. We developed an economic model to predict the cost of trials based on input costs, duration, power, number of sites, recruitment eligibility and consenting rates. Methods: We parameterised the model for three proxy placebo-controlled surgical trials using data from a systematic review, a bespoke cost survey, and from the literature.
The increased interest in utilizing lignin as a feedstock to produce various aromatic compounds requires advanced chemical analysis methods to provide qualitative and quantitative characterization of lignin samples along different technology streamlines. However, due to the lack of commercially available chemical standards, routine quantification of industrially relevant lignin oligomers in comple
Tissue clearing is commonly used for whole-brain imaging but seldom used for brain slices. Here, we present a simple protocol to slice, immunostain, and clear sections of adult rat brains for subsequent high-resolution confocal imaging. The protocol does not require toxic reagents or specialized equipment. We also provide instructions for culturing of rat brain slices free floating on permeable cu
A method is presented for the determination of complex-valued compression and shear elastic moduli of polymers for ultrasound applications. The resulting values, which are scarcely reported in the literature, are found with uncertainties typically around 1% (real part) and 6% (imaginary part). The method involves a setup consisting of a cm-radius, mm-thick polymer ring glued concentrically to a di
Epitaxially grown nanowires have shown promise for photovoltaic applications due to their nanophotonic properties. Moreover, the mechanical properties of nanowires can reduce crystallographic defect formation at interfaces to help enable new material combinations for photovoltaics. One material that stands to benefit from the nanowire morphology is zinc phosphide (Zn3P2), which, despite promising
In architecture and urban geography, discussions on repair, maintenance and adap5ve re-usehave emerged as a crucial intellectual terrain. Temporal aspects of how the urban fabric isused have also emerged as an issue worth theore5cal and empirical a=en5on. Latching ontothese themes, we will present work tracking the history of conten5on around the publiclyowned mee5ng and arts venue in Lund’s Peopl
Analyzing kinetic experiments on protein aggregation using integrated rate laws has led to numerous advances in our understanding of the fundamental chemical mechanisms behind amyloidogenic disorders such as Alzheimer's and Parkinson's diseases. However, the description of biologically relevant processes may require rate equations that are too complex to solve using existing methods, hindering mec
Growing evidence of the microbiome's importance for plant ecology highlights the need for conservation strategies that consider both plants and their microbial partners, the holobiont. Population genomics are valuable tools for designing conservation strategies but rarely accounts for host- or site-specific microbial interactions. Orchids, with their dependence on specific mycorrhizal fungi, exemp
