Experimental liver models: From cell culture techniques to microfluidic organs-on-chip.

Liver Int 2021 May 9. Epub 2021 May 9.

Department of Electronics, Information and Bioengineering, Politecnico di Milano, Milan, Italy.

The liver is one of the most studied organs of the human body owing to its central role in xenobiotic and drug metabolism. In recent decades, extensive research has aimed at developing in vitro liver models able to mimic liver functions to study pathophysiological clues in high-throughput and reproducible environments. Two-dimensional (2D) models have been widely used in screening potential toxic compounds but have failed to accurately reproduce the three-dimensionality (3D) of the liver milieu. Read More

J Neurotrauma 2021 Apr 26. Epub 2021 Apr 26.

Department of Neurosurgery, and Keck School of Medicine, University of Southern California, Los Angeles, California, USA.

Current guidelines for patients experiencing a concussion or mild traumatic brain injury (mTBI) often focus on conservative care and observation. However, mTBI may increase the risk of severe novel psychiatric disorders (NPDs) within 180 days, and long-term management of mTBI should include psychiatric evaluation in patient populations. Retrospective cohort analysis was conducted using 8 years of the Nationwide Readmission Database. Read More

Sci Rep 2021 Mar 5;11(1):5302. Epub 2021 Mar 5.

School of Chemistry, University College Dublin, Belfield, Dublin, Ireland.

Magnetically actuated lab-on-a-chip (LOC) technologies have enabled rapid, highly efficient separation of specific biomarkers and cells from complex biological samples. Nonlinear magnetophoresis (NLM) is a technique that uses a microfabricated magnet array (MMA) and a time varying external magnetic field to precisely control the transport of superparamagnetic (SPM) beads on the surface of a chip based on their size and magnetization. We analyze the transport and separation behavior of SPM monomers and dimers on four MMA geometries, i. Read More

Rapid Manufacturing of Multilayered Microfluidic Devices for Organ on a Chip Applications.

Sensors (Basel) 2021 Feb 16;21(4). Epub 2021 Feb 16.

Nanobioengineering Group, Institute for Bioengineering of Catalonia (IBEC), Barcelona Institute of Science and Technology (BIST), 12 Baldiri Reixac 15-21, 08028 Barcelona, Spain.

Microfabrication and Polydimethylsiloxane (PDMS) soft-lithography techniques became popular for microfluidic prototyping at the lab, but even after protocol optimization, fabrication is yet a long, laborious process and partly user-dependent. Furthermore, the time and money required for the master fabrication process, necessary at any design upgrade, is still elevated. Digital Manufacturing (DM) and Rapid-Prototyping (RP) for microfluidics applications arise as a solution to this and other limitations of photo and soft-lithography fabrication techniques. Read More

Wellcome Open Res 2018 2;3:28. Epub 2021 Feb 2.

Department of Psychology, Emory University, Atlanta, GA, GA30322, USA.

The concept of locus of control of reinforcement was introduced by Julian Rotter and has been the focus of intense research for nearly half a century.  Surprisingly little research has been directed at clarifying antecedents of locus of control (LOC) orientations in adult men apart from a few small studies. We previously identified a number of independent antecedents associated with women's LOC, including features of their parents and early childhood. Read More

Expert opinion-management of chronic myeloid leukemia after resistance to second-generation tyrosine kinase inhibitors.

Leukemia 2020 06 4;34(6):1495-1502. Epub 2020 May 4.

Hammersmith Hospital, Imperial College London, London, UK.

Regardless of line of therapy, treatment goals in chronic phase chronic myeloid leukemia (CML) are: avoid progression to accelerated phase or blast crisis CML such that patients achieve a life expectancy comparable with that of the general population; avoid adverse events (AEs); and restore and maintain quality of life. The most important prognostic factor for achieving these goals is response to tyrosine kinase inhibitors (TKIs) at key milestones. For patients failing a TKI, a treatment change is mandatory to limit the risk of progression and death. Read More

On the Evolution and Functional Diversity of Terpene Synthases in the Pinus Species: A Review.

J Mol Evol 2020 04 8;88(3):253-283. Epub 2020 Feb 8.

Dipartimento per la Innovazione nei Sistemi Biologici, Agroalimentari e Forestali, Università Della Tuscia, Via S. Camillo De Lellis, s.n.c, 01100, Viterbo, Italy.

In the biosynthesis of terpenoids, the ample catalytic versatility of terpene synthases (TPS) allows the formation of thousands of different molecules. A steadily increasing number of sequenced plant genomes invariably show that the TPS gene family is medium to large in size, comprising from 30 to 100 functional members. In conifers, TPSs belonging to the gymnosperm-specific TPS-d subfamily produce a complex mixture of mono-, sesqui-, and diterpenoid specialized metabolites, which are found in volatile emissions and oleoresin secretions.

SinoPedia-A Linked Data Services platform for decentralized knowledge base.

PLoS One 2019 2;14(8):e0219992. Epub 2019 Aug 2.

Shanghai Library/Institute of Scientific & Technical Information of Shanghai, Shanghai, China.

Knowledge bases are largely developed and utilized in academic and industrial fields, such as DBPedia, VIAF, LoC, Getty, and which are published in the Linked Data format. However, if you want to view different resources on these knowledge bases, you have to switch between different web pages from these resources. Therefore, we proposed a decentralized data hub named SinoPedia, which consists of several linked data services and can re-publish these RDF data in one platform. Read More

Mild traumatic brain injury characteristics do not negatively influence cognitive processing therapy attendance or outcomes.

J Psychiatr Res 2019 09 24;116:7-13. Epub 2019 May 24.

Center of Excellence for Stress and Mental Health, VA San Diego Healthcare System, USA; Psychology Service, VA San Diego Healthcare System, USA; Department of Psychiatry, University of California, San Diego, USA.

Some providers have expressed hesitation about the appropriateness of PTSD treatment for veterans with a history of mild traumatic brain injury (mTBI), given concerns that TBI-related sequelae may negatively affect PTSD treatment and/or should be the focus of treatment instead. However, research suggests that those with a history of mTBI can benefit from evidence-based PTSD treatment. To extend these findings, we examined whether specific mTBI injury markers were associated with PTSD treatment attendance and response. Read More
