HLA class, calcineurin inhibitor levels, and the risk of graft failure in kidney recipients with donor-specific antibodies.

Introduction: De novo donor-specific HLA antibody (dnDSA) are associated with poor outcomes. Whether this observation applies to both HLA class I and II dnDSA remains unclear.

Methods: We studied 1236 consecutive kidney recipients who had routine anti-HLA antibody surveillance post-transplant.

Validation of a laboratory spray generation system and its use in a comparative study of hexamethylene diisocyanate (HDI) evaluation methods.

Isocyanates are well-known irritants and sensitizers, and measuring their occupational airborne exposure is challenging due to their high chemical reactivity and semi-volatile nature. This study builds on a previous publication by our team that focused on comparing evaluation methods for isocyanates. The current research aims at developing, validating, and applying a laboratory generation system designed to replicate real-world conditions for spraying clear coats in autobody shops using hexamethylene diisocyanate (HDI)-based products.

Barriers and hurdles delaying governance approval for an ethically approved nationwide clinical trial in pancreatic cancer.

Backgrounds: Streamlined, expedited clinical research is fundamental to rapidly test, translate and implement novel treatments into routine care to improve patient outcomes. The National Mutual Acceptance (NMA) scheme was designed to expedite the ethics approval process, however, growing concerns exist about the fragmented time-consuming governance process needed to actually commence clinical research in Australia. This study reports hurdles and barriers encountered while seeking governance approval for the SCANPatient trial.

Rapid shifts in grassland communities driven by climate change.

Many terrestrial plant communities, especially forests, have been shown to lag in response to rapid climate change. Grassland communities may respond more quickly to novel climates, as they consist mostly of short-lived species, which are directly exposed to macroclimate change. Here we report the rapid response of grassland communities to climate change in the California Floristic Province.
