Ultrafast Untethered Levitation Device Utilized Squeeze Film for Omni‐Directional Transport

Advanced Intelligent Systems, EarlyView.
Untethered levitation device (106 g, 95 × 72 × 45 mm3) on squeeze film is generated by a piezoelectric actuator with onboard electronics (77 g). It achieves frictionless and omnidirectional movement over 1.4 and 3.0 ms−1 on horizontal and inclined surfaces respectively.

Enhanced Embolic Signal Analysis through Ensemble Deep Learning Techniques Utilizing Transfer Learning and Layer Freezing Strategies

Advanced Intelligent Systems, EarlyView.
A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Maternal Sirolimus Treatment Reverses Cardiac Rhabdomyoma‐Induced Hydrops Fetalis in a Twin Gestation With Tuberous Sclerosis Complex

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cardiac rhabdomyomas are often the presenting sign of tuberous sclerosis complex (TSC). Prior reports have shown that maternal sirolimus treatment can reduce rhabdomyomas. We used maternal sirolimus to reverse hydrops fetalis due to a massive cardiac rhabdomyoma in a twin gestation.

Management of Cardiovascular Health Issues in Turner Syndrome: Expert Insights and Expanded Recommendations From the 2024 Guideline Development Team

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner syndrome (TS) is frequently complicated by congenital heart disease (CHD). While left‐sided lesions such as bicuspid aortic valve (BAV) and coarctation of the aorta are the most common structural heart lesions in TS, other anomalies, such as aortic arch malformations, hypoplastic left heart syndrome (HLHS), persistent left superior vena

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.
