Framework Nucleic Acid-Nanobody Fusion Probe-Based Pharmacokinetics Modulation and Analysis for Efficient Positron Emission Tomography Imaging.

Nanobodies are promising for immunoPET imaging due to their excellent antigen recognition and tumor targeting, yet rapid clearance limits their tumor accumulation. Although multimerization and albumin binding can extend their circulation time and improve tumor targeting, a simple and universal method for creating protein multimers is still needed. Here, we leveraged the facile synthesis, controllable size, and precise assembly of DNA nanotechnology to construct CD47-targeted framework nucleic acid-nanobody fusion probes with multiple valences and sizes.

Gender differences in physical activity and sport participation in adults across 28 European countries between 2005 and 2022.

Objective: There is a lack of understanding of the specific types and intensities of physical activity driving the gender gap in overall levels of physical activity, and how these activities are changing over time. We examined the gender gap in specific types and intensities of physical activities in European adults from 2005 to 2022.

Study Design And Methods: This repeated cross-sectional study included data from adults from the Eurobarometer (2005-2022) from 28 European countries.

Effects of combined exposure to PM, O, and NO on health risks of different disease populations in the Beijing-Tianjin-Hebei region.

Air pollution adversely affects people's health. Under the current background of compound air pollution in China, the emission reduction potential of air pollution control has significantly decreased, and there are few studies on multi-pollutant emission reduction and synergistic effects. PM, O, and NO have caused the enormous disease burden and health risks.

Associations of adiposity and device-measured physical activity with cancer incidence: UK Biobank prospective cohort study.

Background: High adiposity and low physical activity are associated with cancer risk. Whether different amounts and intensities of physical activity can mitigate this association is unclear. We aimed to examine the independent and combined associations of adiposity and device-measured physical activity levels of different intensities with cancer incidence and mortality.

Physical Activity and All-Cause Mortality by Age in 4 Multinational Megacohorts.

Importance: Physical activity (PA) guidelines recommend the same amount of PA through adulthood to live longer.

Objective: To explore whether there is an age-dependent association between PA and all-cause mortality and to investigate the age-dependent associations between other modifiable health factors (high educational level, not smoking, not regularly consuming alcohol, healthy body weight, and living without hypertension and diabetes) and mortality.

Design, Setting, And Participants: This cohort study used a pooled analysis of 4 population-based prospective cohorts (National Health Interview Survey, 1997-2018; UK Biobank, 2006-2010; China Kadoorie Biobank, 2004-2008; and Mei Jau, 1997-2016).

Imaging, biomarkers, and vascular cognitive impairment in China: Rationale and design for the VICA study.

Introduction: Vascular cognitive impairment (VCI) is highly heterogeneous, with unclear pathogenesis. Individuals with vascular risk factors (VRF), cerebral small vessel disease (CSVD), and stroke are all at risk of developing VCI. To address the growing challenges posed by VCI, the "Vascular, Imaging and Cognition Association of China" (VICA) was established.

Hyaluronic acid-functionalized MOFs for combined sunitinib and siRNA therapy in renal cell carcinoma.

Sunitinib is a first-line treatment for renal cell carcinoma (RCC), but suffers from drug resistance, causing therapy failure. Therefore, nano-scale delivery systems should be introduced for targeted delivery. Metal-organic frameworks (MOFs) are attractive drug carriers that not only enable multidrug combination therapies but also exert photodynamic effects by incorporating photosensitizers as components.

Regulated Cell Death Pathways in Pathological Cardiac Hypertrophy.

Cardiac hypertrophy is characterized by an increased volume of individual cardiomyocytes rather than an increase in their number. Myocardial hypertrophy due to pathological stimuli encountered by the heart, which reduces pressure on the ventricular walls to maintain cardiac function, is known as pathological hypertrophy. This eventually progresses to heart failure.

Functional investigation and two-sample Mendelian randomization study of primary biliary cholangitis hub genes.

Background: The identification of specific gene expression patterns is crucial for understanding the mechanisms underlying primary biliary cholangitis (PBC) and finding relevant biomarkers for diagnosis and therapeutic evaluation.

Aim: To determine PBC-associated hub genes and assess their clinical utility for disease prediction.

Methods: PBC expression data were obtained from the Gene Expression Omnibus database.

An iron-binding protein of entomopathogenic fungus suppresses the proliferation of host symbiotic bacteria.

Background: Entomopathogenic fungal infection-induced dysbiosis of host microbiota offers a window into understanding the complex interactions between pathogenic fungi and host symbionts. Such insights are critical for enhancing the efficacy of mycoinsecticides. However, the utilization of these interactions in pest control remains largely unexplored.

The co-benefits of active travel interventions beyond physical activity: a systematic review.

Active travel is a widely recognised strategy for promoting active living but its co-benefits beyond increasing physical activity, such as broader health, environmental, and social benefits, have rarely been synthesised. We conducted a systematic review to examine the co-benefits of active travel interventions. Following a preregistered protocol (PROSPERO CRD42022359059), we identified 80 studies for the search period from Jan 1, 2000, to Sept 13, 2022.

Understanding the Relationships Between Physical Activity and Climate Change: An Umbrella Review.

Background: Physical activity is crucial for maintaining health and preventing chronic diseases. However, climate conditions can impact physical activity patterns, and conversely, physical activity can impact climate change. This umbrella review aims to summarize the existing evidence regarding the relationships between physical activity and climate change, as revealed in previous reviews.

Sport Participation Trajectories and Loneliness: Evidence From the Longitudinal Study of Australian Children.

Background: This study aimed to identify patterns of overall, team, and individual sport participation and examine the prospective associations between these patterns and loneliness in young people.

Methods: We analyzed data from 4241 young people, from waves 3 (8-9 y) to 9 (20-21 y) of the Longitudinal Study of Australian Children. We conducted latent class analyses to identify overall and team versus individual sport participation trajectories and used adjusted log-Poisson regression models to examine the associations between these trajectories and loneliness at wave 9.

Degradation and preservation of nitrites in whole blood.

Understanding the factors that influence nitrite degradation in whole blood and developing methods for its stable preservation are crucial for ensuring accurate and reliable forensic identification in cases of nitrite poisoning. This study systematically monitored nitrite degradation and changes in hemoglobin proportions across different initial nitrite concentrations and blood samples. It was revealed that high nitrite concentrations rapidly reduced deoxyhemoglobin levels within the first 15 minutes and subsequently reacted with oxyhemoglobin at a slower rate.
