Discordance between knee and hand-wrist bone age in adolescents: implications for skeletal maturity assessment and its association with thyroid-stimulating hormone levels.

Background: Hand-wrist radiographs may not fully reflect skeletal bone age (BA) during mid-to-late puberty. Knee magnetic resonance imaging (MRI), a non-radiative imaging technique, may provide detailed evaluation of the lower limbs.

Objective: To validate the San Diego MRI-based knee BA atlas in a Chinese adolescent cohort presenting with growth deceleration, evaluate the concordance between knee and hand-wrist BA, and explore factors influencing potential discrepancies.

TransGeneSelector: using a transformer approach to mine key genes from small transcriptomic datasets in plant responses to various environments.

Gene mining is crucial for understanding the regulatory mechanisms underlying complex biological processes, particularly in plants responding to environmental conditions. Traditional machine learning methods, while useful, often overlook important gene relationships due to their reliance on manual feature selection and limited ability to capture complex inter-gene regulatory dynamics. Deep learning approaches, while powerful, are often unsuitable for small sample sizes.

Dentoskeletal characteristics of non-syndromic pierre robin sequence and isolated incomplete cleft palate children: a retrospective case control study.

Background: Pierre Robin sequence (PRS) is characterized by micrognathia, glossoptosis, and upper airway obstruction. This study aimed to compare the dentoskeletal characteristics of children diagnosed with non-syndromic PRS and those with cleft palate.

Methods: This study was conducted on the non-syndromic PRS patients in the database of our hospital.

Single-nuclear transcriptomics of lymphedema-associated adipose reveals a pro-lymphangiogenic stromal cell population.

Chronic lymphedema is a progressive, disfiguring disease that results from dysfunction of the lymphatic vasculature, causing distal accumulation of interstitial fluid, localized development of tissue edema, and expansion of subcutaneous adipose tissue (SAT). As the molecular mechanisms governing SAT remodeling in this disease are unclear, we performed single-nucleus RNA sequencing on paired control and affected SAT biopsies from patients with unilateral lymphedema. Lymphedema samples were characterized by expansion of SAA adipocytes, pro-adipogenic stem cells, and proliferation of lymphatic capillaries.

Pathomics-based machine learning models for predicting pathological complete response and prognosis in locally advanced rectal cancer patients post-neoadjuvant chemoradiotherapy: insights from two independent institutional studies.

This study aimed to construct and validate the machine learning (ML) models to predict pCR and DFS using pathomics.

Method: A retrospective analysis was conducted on 294 patients who received NCRT from two independent institutions.

A novel mutation in the ATP7B gene causing hepatolenticular degeneration in a Chinese family: A case report.

Introduction: Hepatolenticular degeneration (Wilson disease) is an autosomal recessive monogenic disorder caused by mutations in the ATPase copper transporting beta (ATP7B) gene located on human chromosome 13. This gene encodes a copper-transporting P-type ATPase (ATP7B). Recent studies have revealed that the ATP7B gene is predominantly affected by a few hotspot mutations, with the His1069Gln mutation in exon 14 accounting for 50 to 80% of cases.

Methods: A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium, which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P. After stringent quality control measures, 343 single nucleotide polymorphism (SNP) spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS) dataset for further analysis.

Adaptable cascaded registration for personalized maxilla completion and cleft defect volume estimation.

Background: Cone-beam computed tomography (CBCT) images provide high-resolution insights into the underlying craniofacial anomaly in patients with cleft lip and palate (CLP), requiring non-negligible annotation costs to measure the cleft defect for the guidance of the clinical secondary alveolar bone graft procedures. Considering the cumbersome volumetric image acquisition, there is a lack of paired CLP CBCTs and normal CBCTs for learning-based anatomical structure restoration models. Nowadays, the registration-based method relieves the annotation burden, though one-shot registration and the regular mask are limited to handling fine-grained shape variations and harmony between restored bony tissues and the defected maxilla.
