Background and purpose — Cemented fixation is regarded as the gold standard in total knee arthroplasty (TKA). Among working-age patients, there has been controversy regarding the optimal fixation method in TKA. To address this issue, we conducted a register-based study to assess the survivorship of cemented, uncemented, hybrid, and inverse hybrid TKAs in patients aged < 65 years. Patients and meth

Multidisciplinary collaboration between several European dermatology departments has identified isobornyl acrylate (IBOA; CAS 5888-33-5), once deemed a low-risk sensitizer, as a major culprit contact allergen in glucose sensors and insulin pumps, medical devices used by diabetes patients worldwide. Although the patch test modalities of IBOA have been fairly well characterized, intriguing questions

Charge separation dynamics after the absorption of a photon is a fundamental process relevant both for photosynthetic reaction centers and artificial solar conversion devices. It has been proposed that quantum coherence plays a role in the formation of charge carriers in organic photovoltaics, but experimental proofs have been lacking. Here we report experimental evidence of coherence in the charg

Inborn errors of metabolism in adults are still largely unexplored. Despite the fact that adult-onset phenotypes have been known for many years, little attention is given to these disorders in neurological practice. The adult-onset presentation differs from childhood-onset phenotypes, often leading to considerable diagnostic delay. The identification of these patients at the earliest stage of dise

Background: The additional value of including segment 4 (S4) portal branches in right portal vein embolization (rPVE) is debated. The aim of the study was to explore this in a large multicenter cohort. Material and methods: A retrospective cohort study consisting of all patients subjected to rPVE from August 2012 to May 2017 at six Scandinavian university hospitals. PVE technique was essentially t

The Mixed Lineage Leukemia (MLL1, KMT2A) gene is critical for development and maintenance of hematopoietic stem cells (HSCs), however, whether this protein is limiting for HSC development is unknown due to lack of physiologic model systems. Here, we develop an MLL1-inducible embryonic stem cell (ESC) system and show that induction of wild-type MLL1 during ESC differentiation selectively increases

Placebo comparisons are increasingly being considered for randomised trials assessing the efficacy of surgical interventions. The aim of this Review is to provide a summary of knowledge on placebo controls in surgical trials. A placebo control is a complex type of comparison group in the surgical setting and, although powerful, presents many challenges. This Review outlines what a placebo control

Descriptions of crustacean brains have focused mainly on three highly derived lineages of malacostracans: the reptantian infraorders represented by spiny lobsters, lobsters, and crayfish. Those descriptions advocate the view that dome- or cap-like neuropils, referred to as 'hemiellipsoid bodies,' are the ground pattern organization of centers that are comparable to insect mushroom bodies in proces

Background: The clinical demarcation of the syndrome progressive myoclonus ataxia is unclear, leading to a lack of recognition and difficult differentiation from other neurological syndromes. Objectives: The objective of this study was to apply a refined definition of progressive myoclonus ataxia and describe the clinical characteristics in patients with progressive myoclonus ataxia and with isola

The article ‘Whither Plastics?—Petrochemicals, plastics and sustainability in a garbage-riddled world’ discusses a number of recent issues around plastics, including plastics’ dependence on fossil fuels, its contribution to ocean waste, and its possible impact on human health [M. Jefferson, “Whither plastics?—Petrochemicals, plastics and sustainability in a garbage-riddled world,” Energy Res. Soc.

CGRP is a potent dilator of arteries and despite rich perivascular CGRP immunoreactivity in both arteries and veins the role of CGRP in veins remains unknown. The aim of the current study was to compare perivascular CGRP immunoreactivity and expression of CGRP receptor mRNA and CGRP receptor immunoreactivity in rat mesenteric arteries and veins. Furthermore, potential vasomotor effects of CGRP wer
