HIV-1 Vpr-mediated G2 arrest involves the DDB1-CUL4AVPRBP E3 ubiquitin ligase. [PDF]

open access: yesPLoS Pathogens, 2007
Human immunodeficiency virus type 1 (HIV-1) viral protein R (Vpr) has been shown to cause G2 cell cycle arrest in human cells by inducing ATR-mediated inactivation of p34cdc2, but factors directly engaged in this process remain unknown.

Enhancing Lentiviral Purification: Combining CIM QA Monolithic Columns With Design of Experiments Approach

open access: yesELECTROPHORESIS, EarlyView.
Lentiviral vector purification using QA CIM monolith anion‐exchange chromatography was optimized via 96‐well and DOE, increasing recovery from 20% to 90%. The process achieved 3.3‐log host cell protein reduction, decreased particle impurities, and showed high binding capacity, supporting large‐scale manufacturing.

Clinical Applications of 3D Specimen Scanning and Margin Mapping in Musculoskeletal Oncology: A 36 Patient Case Series

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background Text‐based pathology reports inadequately communicate complex three‐dimensional (3D) relationships in musculoskeletal oncology, potentially contributing to errors in re‐resection and adjuvant treatment planning. While our prior 7‐case pilot study established technical feasibility, the scalability of this workflow and its utility as ...

Immunofluorescence assay using Vpr-GFP, HA-Vpr and sdAbs Vpr1A and Vpr2A.

open access: yes, 2014
Immunofluorescence was performed by cotransfecting Hela cells with a plasmid coding for Vpr-GFP (B) or HA-Vpr (C) and increasing amount of a plasmid coding for a sdAb. Vpr-GFP, HA-Vpr and sdAbs were tracked as described in Fig. 3.

Human immunodeficiency virus type 1 Vpr: oligomerization is an essential feature for its incorporation into virus particles

open access: yesVirology Journal, 2010
HIV-1 Vpr, a nonstructural viral protein associated with virus particles, has a positive role in the efficient transport of PIC into the nucleus of non-dividing target cells and enhances virus replication in primary T cells.

The immunosuppressive properties of the HIV Vpr protein are linked to a single highly conserved residue, R90. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND: A hallmark of AIDS progression is a switch of cytokines from Th1 to Th2 in the plasma of patients. IL-12, a critical Th1 cytokine secreted by antigen presenting cells (APCs) is suppressed by Vpr, implicating it as an important virulence ...

Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

open access: yesPolymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.
