From the last 100 to the first 100-outcome after a manufacturer change in reverse fracture arthroplasty.

Purpose: If surgery is indicated for elderly patients suffering a proximal humerus fracture, reverse fracture arthroplasty became the preferred type of treatment due to its good and reliable outcomes over the last decade. Surgeons could choose from a wide range of implants and up to now there was no evaluation, if a change of the manufacturer affects patients` outcome.

Methods: The last 100 patients before and the first 100 after manufacturer change in reverse fracture arthroplasty were evaluated at a level one trauma center, all treated by only 3 senior shoulder surgeons.

[Diagnosis and treatment of perioperative anaemia in elective primary hip and knee arthroplasty : Consensus statement of the "Committee for Perioperative Management" of the Working Group for Endoprosthetics].

Background: Hip and knee arthroplasty remain risk procedures for bleeding complications. The prevalence of preoperative anaemia prior to elective joint replacement is high. There are no standardized guidelines in Germany for the diagnosis and treatment of perioperative anaemia in elective hip and knee arthroplasty.

[Perioperative management of obese patients undergoing elective hip and knee arthroplasty].

Introduction: Obesity is a worldwide growing health crisis, affecting younger and younger age groups and posing new challenges for arthroplasty. Due to increased complication rates in this population, many authors are of the opinion that in patients with a body mass index (BMI) of over 40, the problems outweigh the benefits of surgery and that surgery should be postponed until significant weight reduction has been achieved.

Materials And Methods: A systematic review of electronic databases (PubMed, Embase, Web of Science and the Cochrane Library) was performed.

Pioneering genome editing in parthenogenetic stick insects: CRISPR/Cas9-mediated gene knockout in Medauroidea extradentata.

The parthenogenetic life cycle of the stick insect Medauroidea extradentata offers unique advantages for the generation of genome-edited strains, as an isogenic and stable mutant line can in principle be achieved already in the first generation (G0). However, genetic tools for the manipulation of their genes had not been developed until now. Here, we successfully implement CRISPR/Cas9 as a technique to modify the genome of the stick insect M.

Central projections of nociceptive input originating from the low back and limb muscle in rats.

Since clinical features of chronic muscle pain originating from the low back and limbs are different (higher prevalence and broader/duller sensation of low back muscle pain than limb muscle pain), spinal and/or supraspinal projection of nociceptive information could differ between the two muscles. We tested this hypothesis using c-Fos immunohistochemistry combined with retrograde-labeling of dorsal horn (DH) neurons projecting to ventrolateral periaqueductal grey (vlPAG) or ventral posterolateral nucleus of the thalamus (VPL) by fluorogold (FG) injections into the vlPAG or VPL. C-Fos expression in the DH was induced by injecting 5% formalin into the multifidus (MF, low back) or gastrocnemius-soleus (GS, limb) muscle.

Nomogram models for predicting outcomes in thyroid cancer patients with distant metastasis receiving iodine therapy.

This study aimed to establish and validate prognostic nomogram models for patients who underwent I therapy for thyroid cancer with distant metastases. The cohort was divided into training (70%) and validation (30%) sets for nomogram development. Univariate and multivariate Cox regression analyses were used to identify independent predictors for overall survival (OS) and progression-free survival (PFS).

Perceptions of science, science communication, and climate change attitudes in 68 countries - the TISP dataset.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Influence of label and academic field on cancer stigma and subjective illness theories among medicine and psychology students: a cross-sectional online study.

The growing population of cancer survivors faces psychosocial challenges, including stigma. This study examined stigma toward "persons with cancer" and "cancer survivors" among medicine and psychology students, focusing on the impact of labeling. Additionally, the study explored these students' subjective illness theories of cancer.

Electrophysiological approaches to informing therapeutic interventions with deep brain stimulation.

Neuromodulation therapy comprises a range of non-destructive and adjustable methods for modulating neural activity using electrical stimulations, chemical agents, or mechanical interventions. Here, we discuss how electrophysiological brain recording and imaging at multiple scales, from cells to large-scale brain networks, contribute to defining the target location and stimulation parameters of neuromodulation, with an emphasis on deep brain stimulation (DBS).

Centromere positioning orchestrates telomere bouquet formation and the initiation of meiotic differentiation.

Accurate gametogenesis requires the establishment of the telomere bouquet, an evolutionarily conserved, 3D chromosomal arrangement. In this spatial configuration, telomeres temporarily aggregate at the nuclear envelope during meiotic prophase, which facilitates chromosome pairing and recombination. The mechanisms governing the assembly of the telomere bouquet remain largely unexplored, primarily due to the challenges in visualizing and manipulating the bouquet.

Bioinspired artificial antioxidases for efficient redox homeostasis and maxillofacial bone regeneration.

Reconstructing large, inflammatory maxillofacial defects using stem cell-based therapy faces challenges from adverse microenvironments, including high levels of reactive oxygen species (ROS), inadequate oxygen, and intensive inflammation. Here, inspired by the reaction mechanisms of intracellular antioxidant defense systems, we propose the de novo design of an artificial antioxidase using Ru-doped layered double hydroxide (Ru-hydroxide) for efficient redox homeostasis and maxillofacial bone regeneration. Our studies demonstrate that Ru-hydroxide consists hydroxyls-synergistic monoatomic Ru centers, which efficiently react with oxygen species and collaborate with hydroxyls for rapid proton and electron transfer, thus exhibiting efficient, broad-spectrum, and robust ROS scavenging performance.

Reconstructing skeletal homeostasis through allogeneic hematopoietic stem cell transplantation in myelofibrosis.

Myeloproliferative neoplasm-associated myelofibrosis is a clonal stem cell process characterized by pronounced bone marrow fibrosis associated with extramedullary hematopoiesis and splenomegaly. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) represents the only curative treatment leading to bone marrow fibrosis regression. Here we provide an in-depth skeletal characterization of myelofibrosis patients before and after allo-HSCT utilizing clinical high-resolution imaging, laboratory analyses, and bone biopsy studies.

Construction and iterative redesign of synXVI a 903 kb synthetic Saccharomyces cerevisiae chromosome.

The Sc2.0 global consortium to design and construct a synthetic genome based on the Saccharomyces cerevisiae genome commenced in 2006, comprising 16 synthetic chromosomes and a new-to-nature tRNA neochromosome. In this paper we describe assembly and debugging of the 902,994-bp synthetic Saccharomyces cerevisiae chromosome synXVI of the Sc2.

Metabolic activities are selective modulators for individual segmentation clock processes.

Numerous cellular and molecular processes during embryonic development prompt the fundamental question of how their tempos are coordinated and whether a common global modulator exists. While the segmentation clock tempo scales with the kinetics of gene expression and degradation processes of the core clock gene Hes7 across mammals, the coordination of these processes remains unclear. This study examines whether metabolic activities serve as a global modulator for the segmentation clock, finding them to be selective instead.

Subliminal visual stimulation produces behavioural oscillations in multiple frequencies in a visual integration task.

We perceive our surrounding as a continuous stream of information. Yet, it is under debate, whether our brain processes the incoming information continuously or rather in a discontinuous way. In recent years, the idea of rhythmic perception has regained popularity, assuming that parieto-occipital alpha oscillations are the neural mechanism defining the rhythmicity of visual perception.

Positively charged specificity site in cyclin B1 is essential for mitotic fidelity.

Phosphorylation of substrates by cyclin-dependent kinases (CDKs) is the driving force of cell cycle progression. Several CDK-activating cyclins are involved, yet how they contribute to substrate specificity is still poorly understood. Here, we discover that a positively charged pocket in cyclin B1, which is exclusively conserved within B-type cyclins and binds phosphorylated serine- or threonine-residues, is essential for correct execution of mitosis.

A data-consistent model of the last glaciation in the Alps achieved with physics-driven AI.

25 thousand years ago, the European Alps were covered by the kilometre-thick Alpine Ice Field. Numerical modelling of this glaciation has been challenged by model-data disagreements, including overestimations of ice thickness. We tackle this issue by applying the Instructed Glacier Model, a three-dimensional model enhanced with physics-informed machine learning.

Unveiling pelagic-benthic coupling associated with the biological carbon pump in the Fram Strait (Arctic Ocean).

Settling aggregates transport organic matter from the ocean surface to the deep sea and seafloor. Though plankton communities impact carbon export, how specific organisms and their interactions affect export efficiency is unknown. Looking at 15 years of eDNA sequences (18S-V4) from settling and sedimented organic matter in the Fram Strait, here we observe that most phylogenetic groups were transferred from pelagic to benthic ecosystems.

Non-linear enhancement of ultrafast X-ray diffraction through transient resonances.

Diffraction-before-destruction imaging with ultrashort X-ray pulses can visualize non-equilibrium processes, such as chemical reactions, with sub-femtosecond precision in the native environment. Here, a nanospecimen diffracts a single X-ray flash before it disintegrates. The sample structure can be reconstructed from the coherent diffraction image (CDI).

Comparing microCT Staining and Scanning Methodology for Brain Studies in Various Sizes of Spiders.

Recent advances in microCT are facilitating the investigation of microstructures in spiders and insects leading to an increased number of studies investigating their neuroanatomy. Although microCT is a powerful tool, its effectiveness depends on appropriate tissue preparation and scan settings, particularly for soft, non-sclerotized tissues, such as muscles, organs, and neural tissues. As the application of microCT in spiders is only in its infancy, published protocols are often difficult to implement due to substantial size variation of the specimens.

Preliminary effectiveness of social prescription and virtual patient information in increasing tertiary prevention among cancer patients (ESPRIT): protocol for a single-centre, randomised controlled pilot trial.

Introduction: Tertiary prevention through physical activity and psychosocial support can positively impact patient outcomes, such as physical function and quality of life (QoL). However, more research is required on the effectiveness of strategies designed to increase the uptake of tertiary prevention programmes among cancer patients. Here, we present the protocol for a single-centre, randomised controlled pilot trial testing the preliminary effectiveness of social prescription and virtual patient information in increasing tertiary prevention among cancer patients and support persons (SPs) (ESPRIT "ffectiveness of a ocial escription and virtual patient nformation in increasing ertiary prevention" pilot trial).

Functional leaf and plant use by leafcutter bees: Implications for management and conservation.

Wild solitary bees face a host of challenges from the simplification of landscapes and biodiversity loss to invasive species and urbanization. Pollinator researchers and restoration workers thus far gave much attention to increase flower cover to reduce the impact of these anthropogenic pressures. Over 30% of bee species need nonfloral resources such as leaves and resin for their survival and reproduction.
