Introduction: Multispectral and hyperspectral imaging have emerged as powerful tools in medical diagnostics, particularly in cancer detection, due to their ability to capture rich spectral information beyond human vision. Traditional approaches for cancer detection rely on handcrafted features and conventional machine learning algorithms, which struggle with high-dimensional spectral data, noise interference, and domain adaptation challenges. Deep learning has recently been introduced to address these limitations, yet existing models often lack robust feature extraction, generalization capability, and effective domain adaptation strategies.

Unlabelled: Meteorin-like protein (METRNL) has emerged as a novel adipokine involved in metabolic regulation. However, its role in pediatric obesity and its relationship with insulin resistance remain largely unexplored. In this cross-sectional study, we enrolled 55 children with obesity (34 boys, 21 girls) and 49 normal-weight controls (31 boys, 18 girls).

China confronts rising greenhouse gas (GHG) emissions from transportation sector, particularly under-addressed emissions from heavy-duty diesel vehicles (HDDVs), challenging its carbon neutrality goal by 2060. Using a portable emission measurement system (PEMS), the on-road CO, CH, and NO emissions characteristics and durability of seven typical China-VI HDDVs applied for intercity transportation were evaluated. A direct correlation was observed between increased instantaneous CO emissions and vehicle specific power (VSP), affirming the positive dependency of CO emissions on engine power.

Background: Acute radiation-induced dermatitis refers to skin lesions that usually appear within 90 days of the start of radiotherapy. Although various treatments are available, none have proven fully effective. Exosomes produced by adipose-derived stem cells play crucial roles in enhancing cell regeneration, promoting angiogenesis, regulating inflammation and remodeling the extracellular matrix.

Background: Nostril overexposure is a common aesthetic concern among Asian populations, which significantly affects facial harmony. Traditional surgical interventions carry risks such as substantial trauma and visible scarring. This study aims to evaluate the clinical efficacy of Botulinum Toxin Type A (BoNT-A) injections in treating nostril overexposure using three-dimensional (3D) scanning technology.

At present, there is a significant population of individuals experiencing bone deficiencies caused by injuries, ailments affecting the bones, congenital abnormalities, and cancer. The management of substantial bone defects a significant global orthopedic challenge due to the intricacies involved in promoting and restoring the growth of fresh osseous tissue. Autografts are widely regarded as the "gold standard" for repairing bone defects because of their superior tissue acceptance and ability to control osteogenesis.

We propose two types of structures to achieve the control of Fano and electromagnetically induced transparency (EIT) line shapes, in which dual one-dimensional (1D) photonic crystal nanobeam cavities (PCNCs) are side-coupled to a bus waveguide with different gaps. For the proposed type Ⅰ and type Ⅱ systems, the phase differences between the nanobeam periodic structures of the two cavities are and 0, respectively. The whole structures are theoretically analyzed via the coupled mode theory and numerically demonstrated using the three-dimensional finite-difference time-domain (3D FDTD) method.

  • Silent Brain Infarction (SBI) is associated with cognitive decline and increased stroke risk, particularly in patients with nonvalvular atrial fibrillation (NVAF) having a low CHA2DS2-VASc score.
  • In a study of 301 low-risk NVAF patients, significant differences in blood parameters and echocardiography results were found between those with and without SBI, with Platelet-To-Lymphocyte Ratio (PLR) and left atrial diameter (LAD) identified as independent risk factors.
  • The study established that both PLR and LAD have diagnostic value for SBI, with a combined area under the curve (AUC) indicating moderate predictive ability for identifying patients at

Objective: To investigate serum TL1A levels and their correlation with Th17 cells, IL-17, and IL-21 in children with Graves' disease (GD).

Methods: Thirty-seven children (12 males and 25 females) aged 9-14 years with newly diagnosed and untreated GD were enrolled in this study. Serum TL1A, IL-17, and IL-21 levels were measured using enzyme-linked immunosorbent assay (ELISA).

Ammonia emissions from gasoline vehicles have been confirmed an essential precursor of urban secondary aerosols. To more comprehensively understand the formation mechanisms and better control vehicle-related ammonia, this paper measured the on-road ammonia emissions from six conventional and four hybrid vehicles using a state-of-the-art Quantum Cascade Laser analyzer on urban, rural, and highway routes. The test vehicles emitted 0.

Hypertrophic scars, which result from aberrant fibrosis and disorganized collagen synthesis by skin fibroblasts, emerge due to disrupted wound healing processes. These scars present significant psychosocial and functional challenges to affected individuals. The current treatment limitations largely arise from an incomplete understanding of the underlying mechanisms of hypertrophic scar development.

High exhaust temperature is an intrinsic nature of natural gas engines which underlies power de-rating and thermal aging of after-treatment system; therefore, this study integrates an organic Rankine cycle (ORC) system between engine and it's three-way catalyst (TWC) to address these challenges. ORC facilitates power output enhancement through exhaust energy recovery and alleviates thermal aging by reducing exhaust temperature. To estimate the effectiveness of this hypothesized system, a simulation-based investigation is performed.

Introduction: Stromal cell-derived factor-1 (SDF-1) is a newly discovered small molecule adipocytokine, and research has shown that it is closely related to the occurrence and development of obesity. However, there are currently few research reports on SDF-1 in childhood obesity and nonalcoholic fatty liver disease (NAFLD), and this study aims to explore the relationship between SDF-1 and obesity related indicators in obese children.

Methods: Serum SDF-1 concentrations were measured using enzyme-linked immunosorbent assay (ELISA).

Menispermaceae species, as early-diverging eudicots, can synthesize valuable benzylisoquinoline alkaloids (BIAs) like bisbenzylisoquinoline alkaloids (bisBIAs) and sinomenines with a wide range of structural diversity. However, the evolutionary mechanisms responsible for their chemo-diversity are not well understood. Here, a chromosome-level genome assembly of Menispermum dauricum is presented and demonstrated the occurrence of two whole genome duplication (WGD) events that are shared by Ranunculales and specific to Menispermum, providing a model for understanding chromosomal evolution in early-diverging eudicots.

Survival crises stalk many animals, especially endangered and rare animals. Accurate species identification plays a pivotal role in animal resource conservation. In this study, we developed an animal species identification method called Analysis of whole-GEnome (AGE), which identifies species by finding species-specific sequences through bioinformatics analysis of the whole genome and subsequently recognizing these sequences using experimental technologies.

The challenge of discriminating closely related species persists, notably within clinical diagnostic laboratories for invasive aspergillosis (IA)-related species and food contamination microorganisms with toxin-producing potential. We employed Analysis of the whole-GEnome (AGE) to address the challenges of closely related species within the genus and developed a rapid detection method. First, reliable whole genome data for 77 species were downloaded from the database, and through bioinformatic analysis, specific targets for each species were identified.
