Precuneus activity during retrieval is positively associated with amyloid burden in cognitively normal older carriers.

The precuneus is a site of early amyloid-beta (Aβ) accumulation. Previous cross-sectional studies reported increased precuneus fMRI activity in older adults with mild cognitive deficits or elevated Aβ. However, longitudinal studies in early Alzheimer's disease (AD) are lacking and the relationship to the Apolipoprotein-E () genotype is unclear.

Training and validating a treatment recommender with partial verification evidence.

Background: Current clinical decision support systems (DSS) are trained and validated on observational data from the clinic in which the DSS is going to be applied. This is problematic for treatments that have already been validated in a randomized clinical trial (RCT), but have not yet been introduced in any clinic. In this work, we report on a method for training and validating the DSS core before introduction to a clinic, using the RCT data themselves.

Higher physical activity levels are related to faecal microbiota diversity and composition in young adults.

Increasing physical activity (PA) is recognised as an efficacious approach for preventing and treating cardiometabolic diseases. Recently, the composition of microorganisms living within the gut has been proposed as an important appropriate target for treating these diseases. Whether PA is related to faecal microbiota diversity and composition in humans remains to be ascertained.

More micrometastases, more recurrence? The role of qPCR of PSA mRNA in lymph nodes during prostatectomy.

Background And Objectives: Radical prostatectomy is a standard treatment for prostate cancer, yet about 30% of patients experience rising biochemical markers within a decade post-surgery. Pelvic lymph node sampling during prostatectomy assesses potential lymph node metastases, but standard histological assessments, which typically examine only 2-3 tissue sections, often miss occult metastases. This study assesses the effectiveness of qPCR in detecting PSA coding KLK3 mRNA for identifying lymph node metastases post-prostatectomy and explores the correlation between PSA-mRNA and biochemical recurrence.

Experimental economics for machine learning-a methodological contribution on lie detection.

In this paper, we investigate how technology has contributed to experimental economics in the past and illustrate how experimental economics can contribute to technological progress in the future. We argue that with machine learning (ML), a new technology is at hand, where for the first time experimental economics can contribute to enabling substantial improvement of technology. At the same time, ML opens up new questions for experimental research because it can generate previously impossible observations.

Tracing active members in microbial communities by BONCAT and click chemistry-based enrichment of newly synthesized proteins.

A comprehensive understanding of microbial community dynamics is fundamental to the advancement of environmental microbiology, human health, and biotechnology. Metaproteomics, defined as the analysis of all proteins present within a microbial community, provides insights into these complex systems. Microbial adaptation and activity depend to an important extent on newly synthesized proteins (nP), however, the distinction between nP and bulk proteins is challenging.

- a large-scale dataset of 3D medical shapes for computer vision.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).

The Effects of Reverse Nordic Exercise Training on Measures of Physical Fitness in Youth Karate Athletes.

In karate, the ability to execute high-velocity movements, particularly kicks and punches, is heavily dependent on the strength and power of the lower limb muscles, especially the knee extensors. As such, this study aimed to evaluate the effects of an 8-week eccentric training program utilizing the reverse Nordic exercise (RNE) integrated into karate training compared with regular karate training only on measures of physical fitness in youth karate athletes. Twenty-seven youth karatekas were recruited and allocated to either RNE group (n = 13; age = 15.

Occupational adjustments and work ability of young adult cancer survivors: results from the AYA-Leipzig study.

Purpose: Adolescent and young adult cancer survivors (AYA-CS) face a long working life after treatment, yet factors related to a successful return to work remain largely unexplored. We therefore aimed to investigate the use of occupational adjustments and their impact on work ability upon return to work.

Methods: As part of the AYA-LE study, we surveyed AYA-CS (aged 18-39 at diagnosis) who returned to work and assessed work ability (Work Ability Index) as well as use and benefit of occupational adjustments.

Pericytes and Extracellular Vesicle Interactions in Neurovascular Adaptation to Chronic Arterial Hypertension.

Background: Chronic arterial hypertension restructures the vascular architecture of the brain, leading to a series of pathological responses that culminate in cerebral small-vessel disease. Pericytes respond dynamically to vascular challenges; however, how they manifest under the continuous strain of hypertension has not been elucidated.

Methods And Results: In this study, we characterized pericyte behavior alongside hypertensive states in the spontaneously hypertensive stroke-prone rat model, focusing on their phenotypic and metabolic transformation.

TRPC1 links calcium signaling to cellular senescence in the protection against post-traumatic osteoarthritis.

Transient receptor potential channel 1 (TRPC1) is a widely expressed mechanosensitive ion channel located within the endoplasmic reticulum membrane, crucial for refilling depleted internal calcium stores during activation of calcium-dependent signaling pathways. Here, we demonstrate that TRPC1 activity is protective within cartilage homeostasis in the prevention of cellular senescence associated cartilage breakdown during mechanical and inflammatory challenge. We reveal that TRPC1 loss is associated with early stages of osteoarthritis (OA) and plays a non-redundant role in calcium signaling in chondrocytes.

Bioengineer mesenchymal stem cell for treatment of glioma by IL-12 mediated microenvironment reprogramming and nCD47-SLAMF7 mediated phagocytosis regulation of macrophages.

High expression of cellular self-activated immunosuppressive molecules and extensive infiltration of suppressive immune cells in the tumor microenvironment are the main factors contributing to glioma's resistance to immunotherapy. Nonetheless, technology to modify the expression of glioma cellular self-molecules through gene editing requires further development. This project advances cell therapy strategies to reverse the immunosuppressive microenvironment of glioma (TIME).

Born to be wild: utilizing natural microbiota for reliable biomedical research.

Laboratory mice housed under specific pathogen-free (SPF) conditions are the standard model in biomedical research. However, experiments with a particular inbred mouse strain performed in different laboratories often yield inconsistent or conflicting data due to housing-specific variations in the composition and diversity of SPF microbiota. These variations affect immune and nonimmune cell functions, leading to systemic physiological changes.

Postoperative Hemorrhage and Venous Thromboembolism in Patients with Pituitary Adenomas Under Acetylsalicylic Acid.

Postoperative hemorrhages (POHs) after pituitary adenoma surgery can have devastating consequences for patients. Many patients take acetylsalicylic acid (ASA) for the primary or secondary prevention of cardiovascular or stroke events. However, the impact of continued low-dose ASA use on the risk of postoperative hemorrhage and the frequency of thromboembolic events after discontinuing ASA in these patients remain poorly understood.

Differentiation of Tumors of the Upper Respiratory Tract Using Optical Metabolic Imaging.

Objectives: With over 184,000 new cases and more than 99,000 deaths per year, malignancies of the larynx are a global health problem. Currently, a dedicated screening method enabling a direct onsite diagnosis is missing. This can lead to delayed diagnosis and worse outcomes of the patients.

FcγRIIa-mediated antibody-dependent uptake of SARS-CoV-2 enhances IL-6 expression of monocytes.

This work aimed to investigate interactions between antibody-opsonized SARS-CoV-2 and monocytes enriched from human peripheral blood mononuclear cells (PBMC) to determine whether antibody dependent enhancement might contribute to the pathophysiology of COVID-19. Pre-incubation of SARS-CoV-2 with sera from hospitalized COVID-19 patients led to significantly increased virus uptake and viral replication in monocytes. Remarkably, SARS-CoV-2 pre-incubated with sera from patients with severe COVID-19 but not those with mild disease or post vaccination strongly increased IL-6 secretion by monocytes.

Use It or Lose It: Facilitating the Use of Interactive Data Apps in Psychological Research Data Sharing.

The value of open research data (ORD), a key feature of open science, lies in their reuse. However, the mere online availability of ORD does not guarantee their reuse by other researchers. Specifically, previous meta-scientific research has indicated that the underutilization of ORD is related to barriers at the level of the ORD themselves, potential reusers of ORD, and the broader academic ecosystem.

Video game-based application for fall risk assessment: a proof-of-concept cohort study.

Background: Fall(s) are a significant cause of morbidity and mortality especially amongst elderly with polyneuropathy and cognitive decline. Conventional fall risk assessment tools are prone to low predictive values and do not address specific vulnerabilities. This study seeks to advance the development of an innovative, engaging fall prediction tool for a high-risk cohort diagnosed with diabetes.

Early detection efforts for colorectal and prostate cancer from the patient's perspective over the course of 12 years: results of the KABOT survey study.

Aim: This study investigates the level of knowledge and utilization of colorectal cancer (CRC) and prostate cancer (PCa) early detection measures (EDMs) over a period of 12 years in general practice from the patient's perspective.

Background: The role of general practitioners (GPs) in EDMs for CRC and PCa in Germany is not well-documented with comprehensive data.

Methods: We conducted a patient-centric survey in the German federal state of Berlin-Brandenburg at a 12-year interval to examine the role of GPs in EDMs for CRC and PCa.

'You grow with the allergy': a grounded theory study of families' experiences with food allergy risk or diagnosis in early childhood.

Objective: Childhood food allergy is increasing in western societies. Preventing and managing food allergies is therefore essential for both parents and children. Given the limited previous research on parents' experiences of food allergy prevention in early childhood, this study aimed to develop a grounded theory to understand the experiences and interactions of families whose children are at risk of, or have been diagnosed with, food allergy.

Implementation of the new DGRh S2e guideline on diagnostics and treatment of adult-onset Still's disease in Germany : Implications for clinical practice in rheumatology.

Background: Adult-onset Still's disease (AOSD) is a rare autoinflammatory disease. Since it can lead to variable organ involvement, including life-threatening complications, and due to newly available therapeutic approaches, the German Society for Rheumatology and Clinical Immunology (Deutsche Gesellschaft für Rheumatologie und klinische Immunologie; DGRh) issued a newly developed S2e guideline in December 2022.

Objective: This study aims to investigate the influence of the new guideline on the diagnosis, management, and outcomes of AOSD.

Micro-jet formation induced by the interaction of a spherical and toroidal cavitation bubble.

We investigate experimentally and numerically the interaction between a spherical cavitation bubble and a wall-bounded toroidal cavitation bubble. We demonstrate that shock wave focusing following toroidal bubble initiation induces the formation of micro-jets that pierce the spherical bubble in the torus-axis direction away from the surface, strongest in the anti-phase scenario. The velocity of micro-jets is determined by the initial standoff distance of the spherical bubble from the wall and thus from the toroidal bubble, with peak jet velocities approaching 1000m/s.

Artificial intelligence-based rapid brain volumetry substantially improves differential diagnosis in dementia.

Introduction: This study evaluates the clinical value of a deep learning-based artificial intelligence (AI) system that performs rapid brain volumetry with automatic lobe segmentation and age- and sex-adjusted percentile comparisons.

Methods: Fifty-five patients-17 with Alzheimer's disease (AD), 18 with frontotemporal dementia (FTD), and 20 healthy controls-underwent cranial magnetic resonance imaging scans. Two board-certified neuroradiologists (BCNR), two board-certified radiologists (BCR), and three radiology residents (RR) assessed the scans twice: first without AI support and then with AI assistance.

Longitudinal predictors for internalizing and externalizing symptomatology at age 4: KUNO-Kids cohort study.

Introduction: Numerous early-life risk factors are thought to significantly contribute to the development of psychological problems in toddlerhood. However, these factors have seldom been investigated concomitantly and longitudinally, and few studies include both mothers and fathers. This study examines the longitudinal impact of early environmental, parental, and child-specific risk factors on children's internalizing and externalizing symptomatology at age 4.

Enhancing the outcomes of bariatric surgery with inhibitory control training, electrical brain stimulation and psychosocial aftercare: a pilot study protocol.

Background: Notwithstanding the documented short- and long-term weight loss and remission of physical and mental diseases following bariatric surgery, a significant proportion of patients fail to respond (fully) to treatment in terms of physical and mental health improvement. Mounting evidence links food-specific impulsivity, prefrontal cortex (PFC) hypoactivity and disrupted hormone secretion in bariatric surgery candidates to poorer post-surgical health outcomes. Neuromodulatory treatments like transcranial direct current stimulation (tDCS) uniquely target these neurobehavioral impairments.
