Transpl Int 2021 Sep 15. Epub 2021 Sep 15.

Donation and Transplant Coordination Unit, Hospital Clinic, Associate Professor Surgical Department, University of Barcelona, Barcelona, Spain.

This paper describes a pathway for collaboration between transplant healthcare professionals and organ recipients. Under the umbrella of the European Society for Organ Transplantation (ESOT) a joint initiative started from three Sections and Committees of ESOT: EDTCO (European Donation and Transplant Coordination Organisation), ETHAP (European Transplant Allied Healthcare Professionals) and ELPAT (Ethical, Legal and Psycho-social Aspects of Transplantation). The formal "kick-off" of the Advisory Board Meeting of the European Transplant Patients' Organisation (ETPO) was during the ESOT congress in 2019. Read More

3D-Reactive printing of engineered alginate inks.

Soft Matter 2021 Sep 15;17(35):8105-8117. Epub 2021 Sep 15.

Department of Chemistry, Materials and Chemical Engineering "Giulio Natta", Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milan, Italy.

Alginate is a common component of bioinks due to its well-described ionic crosslinking mechanism and tunable viscoelastic properties. Extrusion-based 3D-printing of alginate inks requires additives, such as gelatin and Pluronic, pre- or post-printing crosslinking processes and/or coextrusion with crosslinkers. In this work, we aim to develop a different printing approach for alginate-based inks, introducing 3D-reactive printing. Read More

Development of a Programme Theory for Early Intervention Vocational Rehabilitation: A Realist Literature Review.

J Occup Rehabil 2021 Sep 15. Epub 2021 Sep 15.

Preventive and Social Medicine, University of Otago, Dunedin, New Zealand.

Purpose Little is currently known about how early intervention vocational rehabilitation (EIVR) works for people with newly acquired neurological conditions such as traumatic brain injury, acquired brain injury and spinal cord injury. This study aims, from a realist framework, to identify relevant literature and develop an initial programme theory to understand how EIVR might work for people experiencing acquired neurological disability. Realist reviews are ideally placed to address the identified knowledge gap as they assist in gaining a deeper understanding of how the intervention works, for whom it works best, and the contexts that promote the activation of desired outcomes.

Early Experience of a Robotic Foregut Surgery Program at a Cancer Center: Video of Shared Steps in Robotic Pancreatoduodenectomy and Gastrectomy.

Ann Surg Oncol 2021 Sep 13. Epub 2021 Sep 13.

Department of Surgical Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Over the past few decades, robotic surgery techniques required to resect gastric and pancreatic malignancies have evolved remarkably; however, the safety and generalizability of robotic pancreatoduodenectomy remain unknown. At our cancer center, gastrectomies and pancreatectomies are performed in a combined foregut minimally-invasive surgery program; this effectively increases the composite case volume and shortens the learning curve for any individual surgeon. In this video, we demonstrate the shared steps in pancreatoduodenectomy and gastrectomy and explain how the skills gained through robotic gastrectomy can be used during robotic pancreatoduodenectomy.

Droplet contact-based spheroid transfer technique as a multi-step assay tool for spheroid arrays.

Lab Chip 2021 Sep 13. Epub 2021 Sep 13.

Department of Bio and Brain Engineering, Korea Advanced Institute of Science and Technology (KAIST), 291 Daehak-ro, Yuseong-gu, Daejeon 34141, Republic of Korea.

Hanging drop plates and low-attachment well plates are suitable for a high throughput screening model of a spheroid, because each drop (or well) contains a single spheroid and the spheroid environment are separated from each other. However, uniform spheroid culture on these devices is difficult as the liquid around the spheroid is replaced by direct pipetting, which can cause spheroid damage or loss, and well-to-well variation. If spheroids need to be cultured for a long time or analyzed through chemical treatment of immunostaining, it becomes a more considerable problem as the number of pipetting action increases.

Advanced data preprocessing for comprehensive two-dimensional gas chromatography with vacuum ultraviolet spectroscopy detection.

J Sep Sci 2021 Sep 12. Epub 2021 Sep 12.

IFP Energies nouvelles, Rond-point de l'échangeur de Solaize BP 3, Solaize, 69360, France.

Comprehensive two-dimensional gas chromatography with vacuum ultraviolet detection results in sizable data for which noise and baseline drift ought to be corrected. As the data is acquired from multiple channels, preprocessing steps have to be applied to the data from all channels while being robust and rather fast with respect to the significant size of the data. In this study, we have described advanced data preprocessing techniques for such data which were not available in the existing commercial software solutions and which were dedicated primarily to noise and baseline correction.

Evaluation of the In Vitro Cytotoxic Activity of Ursolic Acid PLGA Nanoparticles against Pancreatic Ductal Adenocarcinoma Cell Lines.

Materials (Basel) 2021 Aug 29;14(17). Epub 2021 Aug 29.

Department of Lipids and Liposomes, Faculty of Biotechnology, University of Wroclaw, Joliot-Curie 14a, 50-383 Wroclaw, Poland.

Among all the types of cancer, Pancreatic Ductal Adenocarcinoma remains one of the deadliest and hardest to fight and there is a critical unmet need for new drugs and therapies for its treatment. Naturally derived compounds, such as pentacyclic triterpenoids, have gathered attention because of their high cytotoxic potential towards pancreatic cancer cells, with a wide biological activity spectrum, with ursolic acid (UA) being one of the most interesting. However, due to its minimal water solubility, it is necessary to prepare a nanocarrier vehicle to aid in the delivery of this compound. Read More
