A practical method for the synthesis of small peptides using DCC and HOBt as activators in HO-THF while avoiding the use of protecting groups.

The synthesis of peptides in solution proceeds through successive steps involving the removal of a protecting group and the formation of the peptide bond. While most methodological efforts have focused on the development of new protecting groups and coupling agents, methodologies based on minimal protecting groups have been less explored. In this research, a peptide synthesis methodology was developed using DCC and HOBt in THF-HO, avoiding the use of protecting groups, reducing reaction times, and reusing HOBt during successive couplings.

SUV39H1 Ablation Enhances Long-term CAR T Function in Solid Tumors.

Unlabelled: Failure of adoptive T-cell therapies in patients with cancer is linked to limited T-cell expansion and persistence, even in memory-prone 41BB-(BBz)-based chimeric antigen receptor (CAR) T cells. We show here that BBz-CAR T-cell stem/memory differentiation and persistence can be enhanced through epigenetic manipulation of the histone 3 lysine 9 trimethylation (H3K9me3) pathway. Inactivation of the H3K9 trimethyltransferase SUV39H1 enhances BBz-CAR T cell long-term persistence, protecting mice against tumor relapses and rechallenges in lung and disseminated solid tumor models up to several months after CAR T-cell infusion.

Anurocampa (Lepidoptera: Notodontidae): two new species, systematics and immature stages.

Notodontidae (Lepidoptera, Noctuoidea) comprise over 4,000 described species distributed worldwide, among which nearly half are restricted to the Neotropics. Morphology of adults and immatures of Notodontidae have been broadly investigated and many larval, pupal, and adult characters were found to be synapomorphies of subfamilies and tribes. Despite this, the current classification of Notodontidae remains unsettled as most recent classification systems are contradictory due to reliance on incomplete global sampling and, many taxa, especially in the Neotropics, are still informally classified as incertae sedis.

Bridging clinical care and research in Ontario, Canada: Maximizing diagnoses from reanalysis of clinical exome sequencing data.

We examined the utility of clinical and research processes in the reanalysis of publicly-funded clinical exome sequencing data in Ontario, Canada. In partnership with eight sites, we recruited 287 families with suspected rare genetic diseases tested between 2014 and 2020. Data from seven laboratories was reanalyzed with the referring clinicians.

Analyzing the Organoleptic Quality of Commercial Extra Virgin Olive Oils: IOC Recognized Panel Tests vs. Electronic Nose.

Virgin olive oil (VOO) classification into quality categories determines its labeling and market price. This procedure involves performing a series of chemical-physical analyses and, ultimately, a sensory analysis through the panel test. This work explores the analysis of VOOs quality with an electronic olfactory system (EOS) and examines its abilities using the panel test as a reference.
