Cac1 WHD and PIP domains have distinct roles in replisome progression and genomic stability.

Replication-coupled (RC) nucleosome assembly is an essential process in eukaryotic cells to maintain chromatin structure during DNA replication. The deposition of newly-synthesized H3/H4 histones during DNA replication is facilitated by specialized histone chaperones. CAF-1 is an important histone chaperone complex and its main subunit, Cac1p, contains a PIP and WHD domain for interaction with PCNA and the DNA, respectively.

Mega-megacolon: a case report.

Purpose: Large bowel obstruction and megacolon formation secondary to complicated diverticulitis is rare.

Methods: We present a case of an 84-year-old woman surviving large bowel obstruction and mega-megacolon formation secondary to complicated diverticulitis, with an impressive presentation of abdominal distention.

Results: The patient's symptoms, laboratory test results, and imaging were consistent with large bowel obstruction.

Reference Values and Reference Correlations for the Thermal Conductivity and Viscosity of Fluids.

In this paper, reference values and reference correlations for the thermal conductivity and viscosity of pure fluids are reviewed. Reference values and correlations for the thermal conductivity and the viscosity of pure fluids provide thoroughly evaluated data or functional forms and serve to help calibrate instruments, validate or extend models, and underpin some commercial transactions or designs, among other purposes. The criteria employed for the selection of thermal conductivity and viscosity reference values are also discussed; such values, which have the lowest uncertainties currently achievable, are typically adopted and promulgated by international bodies.

Recombinant human bone morphogenetic protein 2 (rhBMP-2) immobilized on laser-fabricated 3D scaffolds enhance osteogenesis.

The regeneration of bone via a tissue engineering approach involves components from the macroscopic to the nanoscopic level, including appropriate 3D scaffolds, cells and growth factors. In this study, hexagonal scaffolds of different diagonals were fabricated by Direct Laser Writing using a photopolymerizable hybrid material. The proliferation of bone marrow (BM) mesenchymal stem cells (MSCs) cultured on structures with various diagonals, 50, 100, 150 and 200μm increased significantly after 10days in culture, however without significant differences among them.
