Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Liquid Metal Reversible Contacts for Flexible Tactile Sensor with High Sensitivity and Wide Detection Range

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a novel flexible tactile sensor based on the unconventional reversible contact behavior between liquid metal droplets (LMDs), with high‐pressure sensitivity and a broad working range. The 2‐LMD‐based sensor is capable of monitoring human motion and physiological signals, while electrical impedance tomography enables precise shape and

4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Topics of Interest in Women With Myeloproliferative Neoplasms

open access: yesAmerican Journal of Hematology, EarlyView.
Women with MPN: life‐cycle phases, specific risks, and influencing factors. ABSTRACT Overview Sex and gender have emerged as central modifiers of disease biology, phenotype, and clinical outcomes in myeloproliferative neoplasms (MPNs). This review will uniquely highlight issues affecting women with MPN and articulate their relevant determinants ...

Tall Stature and Scoliosis Associated With a Novel Homozygous Loss‐of‐Function Missense Variant in NPR3

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT NPR3‐related tall stature is characterized by tall stature, elongated big toes, and additional epiphyses in hand and foot bones. The condition is caused by biallelic loss‐of‐function variants affecting natriuretic peptide receptor 3 (NPR3). Five individuals from four different families have been reported.

Repurposing With Purpose: Treatment of Bachmann–Bupp Syndrome With Eflornithine and Implications for Other Polyaminopathies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Rare diseases impact approximately 1 in 10 people worldwide, and yet, less than 5% of all rare diseases currently have an approved treatment option available. This is due to many challenges unique to rare diseases, including small, diverse patient populations, the cost of drug development that is not proportionate to the number of patients who

Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic

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

open access: yesAnimal 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.

Harnessing μ‐X‐Ray Fluorescence Spectroscopy as a Tool to Assess Extracellular Vesicle‐Induced Biomineralization

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents an innovative approach to evaluate cell‐mediated biomineralization using μ‐X‐ray fluorescence spectroscopy. By generating elemental maps, the evaluation of mineral deposition by osteoblasts can be assessed in terms of both spatial distribution and degree of maturity.
