New divisors in the boundary of the instanton moduli space

open access: yes, 2018
Let ${\mathcal I}(n)$ denote the moduli space of rank $2$ instanton bundles of charge $n$ on ${\mathbb P}^3$. It is known that ${\mathcal I}(n)$ is an irreducible, nonsingular and affine variety of dimension $8n-3$.

It's Time to Unite: Diversity and Coordination of Thymic Stromal Cells for T Cell Selection and Organ Integrity

open access: yesImmunological Reviews, Volume 332, Issue 1, July 2025.
ABSTRACT The thymus is a primary lymphoid organ for generating a diverse yet self‐tolerant T cell repertoire. Among the thymic stromal cells that create the thymic microenvironment, thymic epithelial cells (TECs) have received the most attention because of their distinctive functions in the repertoire selection of T cells. Other types of thymic stromal

Recent Advances in Enzymes and Chemoenzymatic Synthesis of Tetrasaccharide Linkage Region of Proteoglycans

open access: yesChemBioChem, Volume 26, Issue 10, May 27, 2025.
The tetrasaccharide linkage region of proteoglycans is synthesized through a series of well‐controlled enzymatic reactions in nature. The expression, activity, and substrate profile of these biosynthetic enzymes and the latest development of chemoenzymatic synthesis of linkage region‐bearing glycopeptides are summarized in this review.

An efficient technique for enhancing forensic capabilities of Ext2 file system

open access: yesDigital Investigation, 2007
As electronic documents become more important and valuable in the modern era, attempts are invariably made to take undue-advantage by tampering with them. Tampering with the modification, access and creation date and time stamps (MAC DTS) of digital documents pose a great threat and proves to be a major handicap in digital forensic investigation ...

Involvement of GTPases and vesicle adapter proteins in Heparan sulfate biosynthesis: role of Rab1A, Rab2A and GOLPH3

open access: yesThe FEBS Journal, Volume 292, Issue 9, Page 2237-2250, May 2025.
Vesicle trafficking governs the biosynthesis of heparan sulfate (HS) by controlling the positioning of HS‐modifying enzymes within Golgi compartments. The proteins Rab1A and Rab2A play dynamic, compensatory roles that affect HS levels by influencing the transport of these enzymes.
