Absorption of Broadband Low‐Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing

open access: yesAdvanced Science, EarlyView.
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Biocompatibility of root-end filling materials: recent update

open access: yesRestorative Dentistry & Endodontics, 2013
The purpose of a root-end filling is to establish a seal between the root canal space and the periradicular tissues. As root-end filling materials come into contact with periradicular tissues, knowledge of the tissue response is crucial.

CD8+ T cell memory is sustained in mice by hepatic stellate cells

open access: yesHepatology, EarlyView., 2022
HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
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 ...

Expanded Phenotype Associated With an Intronic PPP1R12A Variant: A Case Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal dominant PPP1R12A‐related genitourinary and/or brain malformation syndrome is a recently described multisystem disorder caused by loss‐of‐function variants in the protein phosphatase 1 regulatory subunit 12a (PPP1R12A) gene. To date, 22 affected individuals have been reported with variable brain malformations and genitourinary ...
