An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

open access: yesAdvanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Antibody responses to nasopharyngeal carriage of Streptococcus pneumoniae in adults: A longitudinal household study [PDF]

open access: yes, 2005
Background. Natural immunity to Streptococcus pneumoniae is thought to be induced by exposure to S. pneumoniae or cross-reactive antigens. No longitudinal studies of carriage of and immune responses to S.

Fibrinolytic Titer of Scarlatinal Streptococci.

open access: yesExperimental Biology and Medicine, 1935
Applying the Tillett-Garner plasma-clot technic1 with rate of thrombolysis as the quantitative index, Dack, Woolpert and Hoyne2 found a slight correlation between thrombolytic titer and clinical severity of scarlet fever. At the time of the publication of their paper a similar study of scarlatinal streptococci was in progress in our laboratories We had

De Novo Design of Integrin α5β1 Modulating Proteins to Enhance Biomaterial Properties

open access: yesAdvanced Materials, EarlyView.
NeoNectins are de novo‐designed miniproteins that selectively bind and stabilize the extended open form of integrin α5β1. When grafted onto biomaterials including hydrogel and titanium, they promote cell attachment and spreading in vitro and promoting tissue integration and bone growth in animal models, demonstrating broad potential for regenerative ...

Polyanhydride‐Based Microparticles for Programmable Pulsatile Release of Diphtheria Toxoid (DT) for Single‐Injection Self‐Boosting Vaccines

open access: yesAdvanced Materials, EarlyView.
This study presents a polyanhydride‐based delivery platform for single‐injection, self‐boosting vaccines. The system enables programmable, pulsatile release of diphtheria toxoid with high antigen recovery and is guided by machine learning for tunability. In vivo results show immune responses comparable to multi‐dose regimens, highlighting its potential
