The ability of animals to perceive and respond to sensory information is essential for their survival in diverse environments. While much progress has been made in understanding various sensory modalities, the sense of hygrosensation, which involves the detection and response to humidity, remains poorly understood. In this study, we focused on the hygrosensory, and closely related thermosensory, s
The polyaneuploid cancer cell (PACC) state promotes cancer lethality by contributing to survival in extreme conditions and metastasis. Recent experimental evidence suggests that post-therapy PACC-derived recurrent populations display cross-resistance to classes of therapies with independent mechanisms of action. We hypothesize that this can occur through PACC memory, whereby cancer cells that have
Trackwork planning and scheduling are demanding because they require strategic foresight and must be completed well in advance. In Sweden, trackwork is performed by maintenance contracting companies during an operation period free from trains. In the contractors’ practice, once the maintenance plan is authorised, some unexpected events might interrupt the plan’s execution, leading to uncertainties
Clinical infertility is the inability of a couple to conceive after 12 months of trying. Male factors are estimated to contribute to 30–50% of cases of infertility. Infertility or reduced fertility can result from testicular dysfunction, endocrinopathies, lifestyle factors (such as tobacco and obesity), congenital anatomical factors, gonadotoxic exposures and ageing, among others. The evaluation o
Glucagon-like peptide 1 receptor agonist exenatide (exendin-4) has potential protective capabilities against diabetic kidney disease (DKD). However, the underlying mechanism has not been fully elucidated. The expression of thioredoxin-interacting protein (Txnip) is upregulated during DKD progression by histone acetylation. Sirtuin 1 (SIRT1) is a deacetylase and is decreased in DKD, which indicates
Background: Evidence based medicine (EBM) should be an endeavor within all healthcare professions. Knowledge and understanding of science are important prerequisites of EBM. Objective: The aim was to examine and compare perspectives on science and perceived inhibiting and facilitating factors for the assimilation and implementation of scientific information among clinically working specialist- and
Plant morphogenesis is governed by the mechanics of the cell wall—a stiff and thin polymeric box that encloses the cells. The cell wall is a highly dynamic composite material. New cell walls are added during cell division. As the cells continue to grow, the properties of cell walls are modulated to undergo significant changes in shape and size without breakage. Spatial and temporal variations in c
ABC-stacked multilayer graphene (ABC-MLG) exhibits topological surface flat bands with a divergent density of states, leading to many-body instabilities at charge neutrality. Here, we explore electronic ordering within a mean-field approach with full generic treatment of all spin-isotropic, two-site charge density and spin interactions up to next-nearest-neighbor (NNN) sites. We find that surface
Importance: Despite some promising preclinical and clinical data, it remains uncertain whether remote ischemic conditioning (RIC) with transient cycles of limb ischemia and reperfusion is an effective treatment for acute stroke. Objective: To evaluate the effect of RIC when initiated in the prehospital setting and continued in the hospital on functional outcome in patients with acute stroke. Desig
Whole-body glucose homeostasis is coordinated through secretion of glucagon and insulin from pancreatic islets. When glucose is low, glucagon is released from a-cells to stimulate hepatic glucose production. However, the mechanisms that regulate glucagon secretion from pancreatic a-cells remain unclear. Here we show that in a-cells, the interaction between fatty acid oxidation and glucose metaboli
This article examines two of the most canonical plays in all of Scandinavian and European modern drama – Henrik Ibsen’s Hedda Gabler (1890) and August Strindberg’s A Dream Play (1902) – through the prism of the history of knowledge. The primary claim of the article is that these two plays are paradigmatic literary representations and critiques of one of the main historical processes pertaining to
The aim of this study is to explore pre-service teachers’ procedural and conceptual understanding of pupils’ understanding of mean value, before and after an intervention. Participants are 66 pre-service teachers, and two teacher educators. The data consists of five video-recorded lessons and pre-service teachers’ pre- and post-test discussions. Based on variation theory, the analysis aimed to ide
Kort introduktion till om hur svenska kvinnor vann tillträde till högre studier genom ett riksdagsbeslut 1873 samt presentation av de sätt på vilka Lunds universitet högtidlighållit detta 150-årsjubileum.
Introduction: The analysis of urinary catecholamine metabolites is a cornerstone of neuroblastoma diagnostics. Currently, there is no consensus regarding the sampling method, and variable combinations of catecholamine metabolites are being used. We investigated if spot urine samples can be reliably used for analysis of a panel of catecholamine metabolites for the diagnosis of neuroblastoma. Method
Cat purring, the unusual, pulsed vibration that epitomizes comfort, enjoys a special status in the world of vocal communication research. Indeed, it has long been flagged as a rare exception to the dominant theory of voice production in mammals. A new study presents histological and biomechanical evidence that purring can occur passively, without needing muscle vibration in the larynx controlled b
PURPOSE: To investigate the role of adiposity in the associations between ultra-processed food (UPF) consumption and head and neck cancer (HNC) and oesophageal adenocarcinoma (OAC) in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.METHODS: Our study included 450,111 EPIC participants. We used Cox regressions to investigate the associations between the consumption of
Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other crop pollinators. Field studies demonstrated that agricultural use of neonicotinoid insecticides can negatively affect wild bee species 1,2, leading to restrictions on these compounds 3. However, besides neonicotinoids, field-based evidence of the effects of lands
This chapter looks at three different cases, which extend from literature to protest, to examine the multimodality of translation and translanguaging in intercultural communication. The cases include excerpts from the novel On Earth We Are Briefly Gorgeous, the graphic novel Persepolis and practices of lip-sewing among refugees, as documented in online media. They represent different communicative
In the face of the triple planetary crisis, which includes climate change, biodiversity loss and environmental degradation, there is growing recognition that the environment needs to be re-evaluated and better protected. Recent developments, such as a values assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES),1 the concept of biocultural right
