The population dynamics of clustered consumer-resource spatial patterns: Insights from the demographics of a Turing mechanism.

In ecology, Alan Turing's proposed activation-inhibition mechanism has been abstracted as corresponding to several ecological interaction types to explain pattern formation in ecosystems. Consumer-resource interactions have strong theoretical arguments linking them to both the Turing mechanism and pattern formation, but there is little empirical support to demonstrate these claims. Here, we connect several lines of evidence to support the proposition that consumer-resource interactions can create empirically observed spatial patterns through a mechanism similar to Turing's theory.

German evidence- and consensus-based guideline on the management of penile urethritis.

Urethritis is a common condition predominantly caused by sexually transmitted pathogens such as Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium. It is not possible to differentiate with certainty between pathogens on the basis of clinical characteristics alone. However, empirical antibiotic therapy is often initiated in clinical practice.

This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries.

Methods: MEDLINE and Embase were systematically searched to June 2021.

Hydroclimatic extremes threaten groundwater quality and stability.

Heavy precipitation, drought, and other hydroclimatic extremes occur more frequently than in the past climate reference period (1961-1990). Given their strong effect on groundwater recharge dynamics, these phenomena increase the vulnerability of groundwater quantity and quality. Over the course of the past decade, we have documented changes in the composition of dissolved organic matter in groundwater.

Barriers to early diagnosis and treatment of cervical cancer in Addis Ababa, Ethiopia: qualitative study.

Objective: Cervical cancer remains the most diagnosed and deadly cancer among women in low and middle income countries, including Ethiopia, although it can be controlled if detected and treated early. However, research on contextual barriers to early diagnosis and treatment of cervical cancer is limited in Ethiopia. This study aimed to describe the lived experience of the patients and to explore the barriers to early diagnosis and treatment of cervical cancer.

Empowering personalized oncology: evolution of digital support and visualization tools for molecular tumor boards.

Background: Molecular tumor boards (MTBs) play a pivotal role in personalized oncology, leveraging complex data sets to tailor therapy for cancer patients. The integration of digital support and visualization tools is essential in this rapidly evolving field facing fast-growing data and changing clinical processes. This study addresses the gap in understanding the evolution of software and visualization needs within MTBs and evaluates the current state of digital support.

[Nursing prioritization and rationing decisions in acute care hospitals during the Covid-19 pandemic: a qualitative study].

Nursing prioritization and rationing decisions in acute care hospitals during the Covid-19 pandemic: a qualitative study The Covid-19 pandemic has put decisions regarding prioritization and rationing of care resources on the health policy agenda. The effects on the allocation of nursing resources in clinical practice are unclear. In order to derive implications for future pandemic situations, we analyzed the extent to which decisions were made about the distribution of resources in acute inpatient care and how bottlenecks were dealt with.

Predicting fragment binding modes using customized Lennard-Jones potentials in short molecular dynamics simulations.

Reliable in silico prediction of fragment binding modes remains a challenge in current drug design research. Due to their small size and generally low binding affinity, fragments can potentially interact with their target proteins in different ways. In the current study, we propose a workflow aimed at predicting favorable fragment binding sites and binding poses through multiple short molecular dynamics simulations.

Systematic review and meta-analysis of the prognostic role of fibroblast-activation protein in gastrointestinal cancers.

Background: Gastrointestinal (GI) cancers, particularly pancreatic cancer, are characterized by a dense stromal tumor microenvironment where cancer-associated fibroblasts (CAFs) predominate. CAFs comprise highly heterogeneous subpopulations with different functions, which can be both tumor-promoting and tumor-restraining. This systematic review and meta-analysis aims to comprehensively assess the impact of the CAF marker fibroblast-activation protein (FAP) expression on clinical outcomes in GI cancers.

Development of a StIW111C-based bioresponsive pore-forming conjugate for permeabilizing the endosomal membrane.

Gene expression manipulation is pivotal in therapeutic approaches for various diseases. Non-viral delivery systems present a safer alternative to viral vectors, with reduced immunogenicity and toxicity. However, their effectiveness in promoting endosomal escape, a crucial step in gene transfer, remains limited.

Pharmacologically induced proteolysis of histone deacetylase-6 attenuates influenza virus replication despite limited anti-tumor effects.

The protein deacetylase HDAC6 has been controversially linked to cancer cell proliferation and viral propagation. We analyzed whether a pharmacological depletion of HDAC6 with a recent proteolysis-targeting chimera (PROTAC) kills tumor cells. We show that low micromolar doses of the cereblon-based PROTAC TH170, but not its inactive analog TH170E, induce proteasomal degradation of HDAC6.

Prior knowledge changes initial sensory processing in the human spinal cord.

Prior knowledge changes how the brain processes sensory input. Whether knowledge influences initial sensory processing upstream of the brain, in the spinal cord, is unknown. Studying electric potentials recorded invasively and noninvasively from the human spinal cord at millisecond resolution, we find that the cord generates electric potentials at 600 hertz that are modulated by prior knowledge about the time of sensory input, as early as 13 to 16 milliseconds after stimulation.

In situ quantification of ribosome number by electron tomography.

Ribosomes, discovered in 1955 by George Palade, were initially described as small cytoplasmic particles preferentially associated with the endoplasmic reticulum (ER). Over the years, extensive research has focused on both the structure and function of ribosomes. However, a fundamental question - how many ribosomes are present within whole cells - has remained largely unaddressed.

Gene expression dynamics in fibroblasts during early-stage murine pancreatic carcinogenesis.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by aggressive growth and metastasis, partly driven by fibroblast-mediated stromal interactions. Using RNA sequencing of fibroblasts from early-stage KPC mouse models, we identified significant upregulation of genes involved in adipogenesis, fatty acid metabolism, and the ROS pathway. ANGPTL4, a key adipogenesis regulator, was highly expressed in fibroblasts and promoted pancreatic cancer cell proliferation and migration through paracrine signaling.

Clinical improvements after endoscopic lung volume reduction with valves in patients with advanced emphysema and a 6-min walk test ≤140 m at baseline.

Background: Data regarding the effectiveness and safety of endoscopic lung volume reduction with valves (ELVR) in emphysema patients with a very low 6-min walk test (6MWT) are limited. Patients with severe emphysema and very low exercise capacity, as indicated by a 6MWT ≤140 m, are often excluded from clinical studies on ELVR, assuming limited therapeutic benefits and increased complication risk.

Study Designs And Methods: This study utilised data from the Lungenemphysemregister e.

[Lower urinary tract dysfunction in children].

Lower urinary tract dysfunction (LUTD) is common in children and can significantly impact the quality of life in affected children and their families. This article provides a comprehensive overview of the causes, diagnostics, and treatment, with a particular focus on nonorganic urinary incontinence and nocturnal enuresis. Accurate diagnostics are essential to differentiate between organic and functional causes, as well as to distinguish primary from secondary forms of urinary incontinence.

Beekeepers' perceptions toward a new omics tool for monitoring bee health in Europe.

Pressures on honey bee health have substantially increased both colony mortality and beekeepers' costs for hive management across Europe. Although technological advances could offer cost-effective solutions to these challenges, there is little research into the incentives and barriers to technological adoption by beekeepers in Europe. Our study is the first to investigate beekeepers' willingness to adopt the Bee Health Card, a molecular diagnostic tool developed within the PoshBee EU project which can rapidly assess bee health by monitoring molecular changes in bees.

Nerve transfer of the median flexor pollicis brevis branch to the deep branch of the ulnar nerve for ulnar nerve palsy: a cadaveric feasibility study.

An ulnar nerve (UN) palsy is devastating for hand function, resulting in an intrinsic minus position or claw hand with a loss of pinch grip. Distal nerve transfers facilitate faster reinnervation of hand intrinsic muscles in cases of proximal ulnar nerve lesions. The traditional anterior interosseous nerve (AIN) to UN motor transfer is commonly used, however, this still leads to long reinnervation times for the distal intrinsic muscles, important for the thumb to index pinch grip.

A Low-Symmetry Copper Benzenehexathiol Coordination Polymer with In-Plane Electrical Anisotropy.

Electrically conductive coordination polymers (ECCPs), particularly those incorporating benzenehexathiol (BHT) ligands, are emerging as a distinctive class of electronic materials with tunable semiconducting and metallic properties. However, the exploration of novel ECCPs with low-symmetry structures and electrical anisotropy remains under development. Here, we report the on-water surface synthesis of a novel ECCP, namely Cu5BHT, which exhibits a low-symmetry structure and unique in-plane electrical anisotropy that differs from the well-known Cu3BHT phase.

Informal care for people with dementia in Europe.

Introduction: Informal care estimates for use in health-economic models are lacking. We aimed to estimate the association between informal care time and dementia symptoms across Europe.

Methods: A secondary analysis was performed on 13,529 observations in 5,369 persons from 9 European pooled cohort or trial studies in community-dwelling persons with dementia.

Dissociative episodes and concurrent heart rate in patients with PTSD - An ecological momentary assessment.

Dissociative symptoms are a frequent complication in posttraumatic stress disorders affecting about a third of all PTSD patients. While theoretical models predict a physiological hypoarousal during posttraumatic dissociations, empirical evidence is lacking. We addressed this by studying spontaneously occurring dissociative symptoms and related heart rate changes in an ecological momentary assessment.

"Y" Configuration of the Arterial Pedicle or the Use of a Saphenous Vein Graft for Microsurgical Reconstruction in the Old and Diseased-A Retrospective Study.

Non-healing soft tissue defects pose challenges to treating physicians. Microsurgical reconstruction is a treatment option for achieving wound closure and limb salvage. These free tissue transfers are often challenging due to associated risk factors.

Skin Physiological Parameters and Their Association with Severe Atopic Dermatitis in Mongolian Children.

: Atopic dermatitis (AD) is a chronic skin condition that weakens the skin barrier, leading to increased trans-epidermal water loss and reduced skin moisture. Understanding how these changes in the skin barrier relate to AD severity in Mongolian children may offer insights that could apply to other regions facing similar environmental challenges. : A cross-sectional study was conducted at the National Dermatology Center of Mongolia, involving 103 children with AD.
