Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

A multimodal quad‐finger soft robotic hand (QDO hand) uses dual‐chamber straight–curved origami prismatic (SCOP) origami actuators. By coordinating positive and negative pressurization in the two chambers, each finger produces axial extension, contraction and bidirectional bending.

ABSTRACT Nonlinear control systems are an integral part of complex engineering systems. The main difference from linear systems is their ability to adapt to changes and unpredictable conditions. These systems exhibit behaviors that cannot be predicted by simple linear equations, making them essential for applications requiring precise control over a ...

Pathogenic PF4/Polyanion ELISA‐Negative Antibodies in HIT
ABSTRACT Background Platelet factor 4‐polyanion enzyme‐linked immunosorbent assays (ELISAs) are considered highly sensitive for diagnosing heparin‐induced thrombocytopenia (HIT), such that current practice guidelines recommend use of ELISA‐negative results to exclude HIT.

ABSTRACT Noonan syndrome (NS) is a genetically heterogeneous disorder characterized by a broad spectrum of clinical features resulting from dysregulation of the RAS/MAPK pathway. Although complex genotypes are increasingly recognized in NS, cases harboring two distinct pathogenic variants in different NS genes remain extremely rare.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease
ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

ABSTRACT Since 2015, Ann and Robert H. Lurie Children's Hospital has performed diagnostic testing for infants who screen positive for mucopolysaccharidosis type II (MPS II) on the Illinois newborn screen. Preliminary diagnostic testing includes measurement of plasma iduronate‐2‐sulfatase enzyme activity and urinary glycosaminoglycan analysis, followed ...

ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.

Vascular Abnormalities in Hypermobile Ehlers–Danlos Syndrome: A Retrospective Cohort Study
ABSTRACT Hypermobile Ehlers–Danlos syndrome (hEDS), while generally free from severe vascular complications, may occasionally present with cardiac and vascular abnormalities that warrant specific investigation. While studies have been conducted on the prevalence of cardiac involvement, none have focused on vascular aspects. This retrospective study was

Defining Features of Gabriele‐de Vries Syndrome in Adults: A Case Report and Literature Review
ABSTRACT Gabriele‐de Vries syndrome (GADEVS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the YY1 gene. Like most rare genetic syndromes, the adult manifestations of GADEVS remain poorly defined. Here, we describe the oldest patient reported to date with GADEVS—a 63‐year‐old woman with a c.1177_1179del YY1 variant ...
