An unprecedented double photoexcitation mechanism for photoswitching in conjugated-dienes to trigger physiological processes for photopharmacology.

The optical control of physiological processes with high precision using photoswitches is an emerging strategy for non-invasive diagnosis and therapies, providing innovative solutions to complex biomedical challenges. Light-responsive cyclic conjugated-dienes (cCDs) have long been recognized for their 4π-photocyclization; however, photoswitching behaviour in medium-sized cCDs has recently been reported, representing a pioneering discovery in the field. Reinforced by previous experimental evidence corroborating the Woodward-Hoffmann rules, this report provides insight into the origin of the exotic dual photoexcitation mechanism devised to achieve thermo-reversible photoswitching in large cCDs with cyclodeca-1,3-diene as a prototype.

Donor Regulatory T-Cell Therapy to Prevent Graft-Versus-Host Disease.

Allogeneic hematopoietic cell transplantation (HCT) is a curative therapy limited by graft-versus-host disease (GVHD). In preclinical studies and early-phase clinical studies enrichment of donor regulatory T cells (Tregs) appears to prevent GVHD and promote healthy immunity.We enrolled 44 patients on an open-label, single-center, phase 2 efficacy study investigating if a precision selected and highly purified Treg cell therapy manufactured from donor mobilized peripheral blood improves one-year GVHD-free relapse free survival (GRFS) after myeloablative conditioning (trial NCT01660607).

What comes next: the fate of germa-, stanna-, and plumba--dodecaborate based electrolytes in calcium ion batteries.

Recent investigations on plumba- and stanna--dodecaborate-based electrolytes for alkali metal-ion batteries have demonstrated improved ionic conductivities at elevated temperatures. However, the potential of germa, stanna, and plumba borane in divalent ion batteries is uncertain. To address this knowledge gap, a theoretical approach has been adopted to explore the potential of Ge-, Sn-, and Pb-based borane anions as electrolytes for CIBs.

The Endodontic Treatment of Three-Rooted Maxillary Premolar Resembling a Small Molar: A Case Report.

An appropriate access cavity, sufficient cleaning, proper shape, and full obturation are necessary for a root canal to be successful. In the earliest stages of therapy, the location of all root canals within the tooth is crucial. Even if the morphology of most teeth is normal, some variations should be acknowledged.

Validation of the Language ENvironment Analysis (LENA) Automated Speech Processing Algorithm Labels for Adult and Child Segments in a Sample of Families From India.

Purpose: The Language ENvironment Analysis (LENA) technology uses automated speech processing (ASP) algorithms to estimate counts such as total adult words and child vocalizations, which helps understand children's early language environment. This ASP has been validated in North American English and other languages in predominantly monolingual contexts but not in a multilingual context like India. Thus, the current study aims to validate the classification accuracy of the LENA algorithm specifically focusing on speaker recognition of adult segments (AdS) and child segments (ChS) in a sample of bi/multilingual families from India.
