The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Bone: Aneurysmal bone cysts [PDF]

open access: yesAtlas of Genetics and Cytogenetics in Oncology and Haematology, 2012
The most widely accepted pathogenetic mechanism of aneurysmal bone cysts has long involved a local circulatory disturbance leading to markedly increased venous pressure and the development of a dilated and enlarged vascular bed within the affected bone area.

Thrombospondin‐4 is upregulated in abdominal aortic aneurysm: A vasoprotective response with potential therapeutic relevance

open access: yesBritish Journal of Pharmacology, EarlyView.
TSP4 is upregulated in human and experimental AAA. TSP4 knockdown accelerated AAA formation and exacerbated both vascular inflammation and remodelling, emphasizing that TSP4 upregulation may represent a protective response against AAA. Our findings suggest that preserving TSP4 could be a useful strategy in the clinical management of AAA.

Bone: Aneurysmal bone cysts [PDF]

open access: yesAtlas of Genetics and Cytogenetics in Oncology and Haematology, 2011
Aneurysmal bone cysts (ABC) are benign lesions that occur more frequently in the metaphyses of long bones, especially distal femur, the proximal tibia and vertebral posterior bodies. It can occur at any age but most patients are diagnosed in the first 2 decades of life.

Examining the Role of Artificial Intelligence in Assessment: A Comparative Study of ChatGPT and Educator‐Generated Multiple‐Choice Questions in a Dental Exam

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Aim To compare the item difficulty and discriminative index of multiple‐choice questions (MCQs) generated by ChatGPT with those created by dental educators, based on the performance of dental students in a real exam setting. Materials and Methods A total of 40 MCQs—20 generated by ChatGPT 4.0 and 20 by dental educators—were developed based on ...

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

open access: yesThe FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

Unicameral (simple) and aneurysmal bone cysts: the effect of insufficient curettage on recurrence

open access: yesThe Pan African Medical Journal, 2016
INTRODUCTION: curettage of the cyst and bone grafting are the most common methods used in the treatment of unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC).

Aneurysmal Bone Cyst: An Uncommon Secondary Event in Calcaneal Chondroblastoma [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2016
Chondroblastoma is an uncommon benign bone tumour, involvement of epiphysis of long bones is typical. Chondroblastoma of the calcaneum is uncommon and its association with secondary aneurysmal bone cyst is even rarer.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

open access: yesThe FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular
