Typical Crossmodal Numerosity Perception in Preterm Newborns.

Multisens Res 2021 May 12:1-22. Epub 2021 May 12.

Department of Developmental Neuroscience, IRCCS Fondazione Stella Maris, 56128 Calambrone, Pisa, Italy.

Premature birth is associated with a high risk of damage in the parietal cortex, a key area for numerical and non-numerical magnitude perception and mathematical reasoning. Children born preterm have higher rates of learning difficulties for school mathematics. In this study, we investigated how preterm newborns (born at 28-34 weeks of gestation age) and full-term newborns respond to visual numerosity after habituation to auditory stimuli of different numerosities.

Isolation of intact extracellular vesicles from cryopreserved samples.

PLoS One 2021 13;16(5):e0251290. Epub 2021 May 13.

Department of Surgery, Center for Engineering in Medicine and BioMEMS Resource Center Massachusetts General Hospital, Harvard Medical School, Boston, MA, United States of America.

Extracellular vesicles (EVs) have emerged as promising candidates in biomarker discovery and diagnostics. Protected by the lipid bilayer, the molecular content of EVs in diverse biofluids are protected from RNases and proteases in the surrounding environment that may rapidly degrade targets of interests. Nonetheless, cryopreservation of EV-containing samples to -80°C may expose the lipid bilayer to physical and biological stressors which may result in cryoinjury and contribute to changes in EV yield, function, or molecular cargo.

Intra-articular silencing of periostin via nanoparticle-based siRNA ameliorates post-traumatic osteoarthritis in mice.

Arthritis Rheumatol 2021 May 13. Epub 2021 May 13.

Department of Orthopaedic Surgery, Musculoskeletal Research Center, Washington University, School of Medicine, St. Louis, MO, United States.

Objective: Recent evidence delineates an emerging role of Periostin (Postn) in osteoarthritis (OA) as its expression subsequent to knee injury is detrimental to the articular cartilage. We hypothesize that intra-articular knockdown of Postn in a murine model of post-traumatic OA would ameliorate OA.

Methods: Post-traumatic OA was induced in 10-week-old male C57BL/6J mice (n=24) by destabilization of the medial meniscus (DMM) and analyzed 8-week post-surgery. Read More
