Artificial intelligence-assisted imaging biosensors have attracted increasing attention due to their flexibility, allowing for the digital image analysis and quantification of biomarkers. While deep learning methods have led to advancements in biomarker identification, the diversity in the density and adherence of targets still poses a serious challenge. In this regard, we propose CellNet, a neural network model specifically designed for detecting dense targets.

Bone is a multifaceted tissue requiring orchestrated interplays of diverse cells within specialized microenvironments. Although significant progress has been made in understanding cellular and molecular mechanisms of component cells of bone, revealing their spatial organization and interactions in native bone tissue microenvironment is crucial for advancing precision medicine, as they govern fundamental signaling pathways and functional dependencies among various bone cells. In this study, we present the first integrative high-resolution map of human bone and bone marrow, using spatial and single-cell transcriptomics profiling from femoral tissue.

Aging increases the risk for Alzheimer's disease (AD), driving pathological changes like amyloid-β (Aβ) buildup, inflammation, and oxidative stress, especially in the prefrontal cortex (PFC). We present the first subcellular-resolution spatial transcriptome atlas of the human prefrontal cortex (PFC), generated with Stereo-seq from six male AD cases at varying neuropathological stages and six age-matched male controls. Our analyses revealed distinct transcriptional alterations across PFC layers, highlighted disruptions in laminar structure, and exposed AD-related shifts in layer-to-layer and cell-cell interactions.

This study presents the development of a magnetic relaxation switching (MRS) immunosensor for the sensitive detection of chlorpyrifos (CPF) with a signal amplification strategy using Pd/Cu-TCPP(Fe) hybrid nanosheets and polydopamine (PDA). Pd/Cu-TCPP(Fe) nanosheets, which exhibit high peroxidase-like activity and excellent storage stability, making them suitable replacements for natural enzymes in biosensors, are further functionalized with goat anti-mouse IgG (Ab) to construct an immunosensor. The mechanism relies on the competition between free CPF and the immobilized bovine serum albumin-CPF conjugates for antibody binding, which modulates the aggregation of magnetic nanoparticles (MNPs) that are related to the transverse relaxation time.

Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM< the 1st quartile), concordant (the 1st quartile ≤BMI-PGM View Article and Find Full Text PDF

Background: Physical fitness (PF) is important for children's physical and cognitive development. There is increasing interest in the relationship between physical fitness, and executive function. Since it is unclear which physical fitness component benefits which domain of executive functioning, it's challenging to develop effective physical intervention programs for children with executive functioning disorders.

Adipose-derived stem cells (ADSCs) have emerged as a promising resource for craniofacial bone regeneration due to their high abundance and easy accessibility, significant osteogenic potential, versatile applications, and potential for personalized medicine, which underscore their importance in this field. This article reviews the current progress of preclinical studies that describe the careful selection of specific ADSC subpopulations, key signaling pathways involved, and usage of various strategies to enhance the osteogenic potential of ADSCs. Additionally, clinical case reports regarding the application of ADSCs in the repair of calvarial defects, cranio-maxillofacial defects, and alveolar bone defects are also discussed.

Article Synopsis
  • - The study investigates the link between muscle mass, strength, quality, and respiratory diseases specifically in a Chinese population, using data from the China Kadoorie Biobank.
  • - Researchers followed 17,510 participants over approximately 4.82 years and found that those with low grip strength and poor arm muscle quality had significantly higher risks of developing respiratory diseases, with hazard ratios of 1.31 and 1.25, respectively.
  • - The results suggest that low grip strength and arm muscle quality are more predictive of respiratory disease risk compared to overall muscle mass, emphasizing their importance as health indicators.

Background: Pertussis resurgence has been reported worldwide in the past two decades. Pertussis is still endemic and difficult to control though with universal vaccination in children. The resurgence may be related to multiple variables, such as increased disease awareness and laboratory tests, waning of immunity following vaccination, and/or genetic mutations of Bordetella pertussis.

Objectives: Despite the evident potential benefits of engaging in physical activity (PA) for older adults with subjective cognitive decline (SCD), their PA levels remains low. Previous research has predominantly focused on PA behaviors in individuals with dementia/mild cognitive impairment, with limited attention given to those with SCD. Therefore, this study aims to identify key factors influencing PA behavior in older adults with SCD based on the Self-Determination Theory (SDT) and the capability-opportunity-motivation (COM-B) model.

Multiple and ultrasensitive detection of pathogenic bacteria is critical but remains a challenge. Here, we introduce a digital assay for multiplexed and target DNA amplification-free detection of pathogenic bacteria using botryoidal-like fluorescent polystyrene dots (PS-dots), which were first prepared through the hybridization reaction between primer exchange reaction chains and polystyrene nanospheres that encapsulated polymer dots for signal preamplification. The pathogenic bacteria's DNA was cleavaged by the argonaute (Ago) protein-mediated multiple and precise cleavage reactions, where the obtained target sequences bridged the magnetic beads (MBs) and botryoidal-like PS-dots via a hybridization reaction, and the fluorescent MB-botryoidal PS-dot complexes were utilized as digital probes based on colors and sizes for digital encoding.
