7-Azido-N,N-diethyl-4,5-O-isopropylidene-4-C-methyl-3,6-anhydro-7-deoxy-d-glycero-d-manno-heptonamide

open access: yesActa Crystallographica Section E, 2009
The reaction of 5-azido-5-deoxy-2,3-O-isopropylidene-2-C-methyl-d-ribose with N,N-diethyl-2-(dimethylsulfuranylidene)acetamide gave the title compound, C15H26N4O5, as the major product arising from initial formation of an epoxide which was subsequently ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Причини и поÑледици на повредите на градниот кош во мирновременÑки и воени уÑлови

open access: yes, 2017
We had 107 patients with chest injuries – 95 of them were blunt wounds and 12 were wounds from weapons (rifles, revolvers, shotguns, knives, bayonets ...).Chest injuries are, as serious in the peaceful-time, as in the military conditions. They bring into

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Quantum-group-invariant D n + 1 2 $$ {D}_{n+1}^{(2)} $$ models: Bethe ansatz and finite-size spectrum

open access: yesJournal of High Energy Physics
We consider the quantum integrable spin chain models associated with the Jimbo R-matrix based on the quantum affine algebra D n + 1 2 $$ {D}_{n+1}^{(2)} $$ , subject to quantum-group-invariant boundary conditions parameterized by two discrete variables p

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
