Functional Dendrimer Nanogels for DNA Delivery and Gene Therapy of Tumors

open access: yesAngewandte Chemie, EarlyView.
Dendrimer nanogels are designed by emulsion‐free method, endowing them with dual‐active groups, o‐hydroxyl amine, temperature‐responsiveness, polyampholyte property, and self‐triggered aminolysis. With these unique characters, dendrimer nanogels display high gene transfection and therapeutic efficacies with low side effects, thus solving the dilemma ...

Enhanced Knee Kinematics: Leveraging Deep Learning and Morphing Algorithms for 3D Implant Modeling [PDF]

open access: yesarXiv
Accurate reconstruction of implanted knee models is crucial in orthopedic surgery and biomedical engineering, enhancing preoperative planning, optimizing implant design, and improving surgical outcomes. Traditional methods rely on labor-intensive and error-prone manual segmentation.

Isolation of Acanthamoeba isolates belonging to T2, T3, T4 and T7 genotypes from environmental samples in Ankara, Turkey [PDF]

open access: yes, 2004
Acanthamoeba keratitis is a blinding infection that is becoming increasingly important in human health. Early diagnosis is a prerequisite for successful treatment and requires identification of Acanthamoeba at the genotypic level.

Multi‐Risk‐Level Sarcopenia‐Prone Screening via Machine Learning Classification of Sit‐to‐Stand Motion Metrics from Wearable Sensors

open access: yesAdvanced Intelligent Systems, EarlyView.
A machine learning approach utilizes micro inertial measurement units (μIMUs) for noninvasive sarcopenia screening through a sit‐to‐stand test. With 53 older participants wearing IMUs, 510 features are extracted across four motion phases. Five algorithms (support vector machine, K‐nearest neighbors, decision tree, linear discriminant analysis, and ...

StraightTrack: Towards Mixed Reality Navigation System for Percutaneous K-wire Insertion [PDF]

open access: yesarXiv
In percutaneous pelvic trauma surgery, accurate placement of Kirschner wires (K-wires) is crucial to ensure effective fracture fixation and avoid complications due to breaching the cortical bone along an unsuitable trajectory. Surgical navigation via mixed reality (MR) can help achieve precise wire placement in a low-profile form factor.

Investigation of Force Decay in Aesthetic, Fibre-Reinforced Composite Orthodontic Archwires [PDF]

open access: yes, 2015
Background/Objectives: Because polymer-based materials typically exhibit viscoelastic properties, the objective was to determine if commercially available, aesthetic, fibre-reinforced composite archwires maintain continuous forces without undergoing ...

Children With 22.Q.11.2 Deletion Syndrome: Sleep‐Disordered Breathing and Management

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Patients with 22q11.2 deletion syndrome (22q11DS) are predisposed to obstructive sleep apnea (OSA) due to an abnormal craniofacial anatomy with pharyngeal hypotonia, retrognathia, micrognathia, and glossoptosis. The aim of the study was to describe the prevalence and management of OSA in a cohort of children with 22q11DS.

Acquiring Submillimeter-Accurate Multi-Task Vision Datasets for Computer-Assisted Orthopedic Surgery [PDF]

open access: yesarXiv
Advances in computer vision, particularly in optical image-based 3D reconstruction and feature matching, enable applications like marker-less surgical navigation and digitization of surgery. However, their development is hindered by a lack of suitable datasets with 3D ground truth.
