Received: 17 December 2022;  Published: 18 April 2023;  doi: 10.21926/jept.2302016

Abstract

In this work with CFD simulations, the evaluation of the supercritical anti-solvent (SAS) process for producing nanoparticles from an expanded solution of ethanol/solute in carbon dioxide is reported. The influence of the solution and antisolvent flow rates on mean particle size, the flow dynamic, and the supercritical mixture's jet velocity must be well established in the literature and analyzed. The high flow rate of the anti-solvent resulted in increased mean particle sizes for all studied cases. At the lowe [...]

Cisplatin-Based Neoadjuvant Chemotherapy for Elderly Patients with Muscle-Invasive Bladder Cancer: Is It Feasible?

Received: 23 July 2021;  Published: 08 November 2021;  doi: 10.21926/obm.geriatr.2104183

Abstract

Cisplatin-based neoadjuvant chemotherapy (C-NAC) has been the standard of care in localized muscle-invasive bladder cancer (MIBC). However, the feasibility and benefit of C-NAC in elderly patients remain uncertain since this population has always been underrepresented in pivotal trials and is often barred from chemotherapy in routine practice because of their perceived frailty. Therefore, in order to evaluate the effectiveness of C-NAC in elderly patients with MIBS, we retrospectively reviewed the medical files of [...]

The P2X7 Receptor Antagonist AZ10606120 Does Not Alter Graft-Versus-Host Disease Development and Increases Serum Human Interferon-γ in a Humanized Mouse Model

Received: 06 June 2022;  Published: 06 September 2022;  doi: 10.21926/obm.transplant.2203166

Abstract

Allogeneic hematopoietic stem cell transplantation is a curative therapy for hematological malignancies, but its efficacy is limited by graft-versus-host disease (GVHD). This life-threatening disorder develops when donor (graft) immune cells cause inflammatory damage to recipient (host) tissues. The immune cell receptor channel P2X7 and its ligand adenosine 5’-triphosphate (ATP) have been implicated in GVHD pathogenesis. Therefore, this signaling axis represents a potential therapeutic target. This study aime [...]

Abstract

The current article describes the application of the Compassion Focussed (CF) formulation to the interaction between individuals and their social context. The standard CF formulation [1] would see the person’s fears as inadvertently reinforced by their attempts to cope with the underlying issue. However, sometimes such attempts to cope can also reinforce the fears of another person or party. Interpersonal CF formulations could provide a compassionate, non-blaming way of enlightening people in their interactions to [...]
