Peripheral Blood Mononuclear Cell-Related Biomarkers in Schizophrenia.

Introduction: Schizophrenia is a severe mental illness causing significant impairment in personal, family, social, educational, occupational, and other important areas of life. While there is no widely accepted endophenotype, peripheral blood cells may serve as an accessible model of intracellular changes in schizophrenia.

Methods: We reviewed the literature on the query "peripheral blood mononuclear cells AND schizophrenia" in Medline (Pubmed), selecting studies that searched for specific biomarkers of schizophrenia.

3D Bioprinting of Hyaline Articular Cartilage: Biopolymers, Hydrogels, and Bioinks.

The musculoskeletal system, consisting of bones and cartilage of various types, muscles, ligaments, and tendons, is the basis of the human body. However, many pathological conditions caused by aging, lifestyle, disease, or trauma can damage its elements and lead to severe disfunction and significant worsening in the quality of life. Due to its structure and function, articular (hyaline) cartilage is the most susceptible to damage.

A pilot study to assess the performance of a rapid ultrasound particle agglutination method for the detection of HIV antibodies.

Anti-HIV antibody screening and confirmatory tests include rapid diagnostics tests (RDT), which have limited sensitivity, and high-sensitivity ELISA and western blot tests, which are laborious and require technical proficiency. Thus, there is an unmet need for novel rapid, simple, and highly sensitive tests. A pilot study was conducted to assess the performance of a recently developed ultrasound particle agglutination (UPA) method for high-sensitivity HIV antibody detection using 51 confirmed positive and 310 presumably negative plasma samples, and 6 commercially available anti-HIV-1 seroconversion panels (total 56 members).

Rheumatoid Arthritis: Applicability of Ready-to-Use Human Cartilaginous Cells for Screening of Compounds with TNF-Alpha Inhibitory Activity.

In the context of modern drug discovery, there is an obvious advantage to designing phenotypic bioassays based on human disease-relevant cells that express disease-relevant markers. The specific aim of the study was to develop a convenient and reliable method for screening compounds with Tumor Necrosis Factor-alpha (TNF-α) inhibitory activity. This assay was developed using cryopreserved ready-to-use cartilage-derived cells isolated from juvenile donors diagnosed with polydactyly.

A rapid ultrasound particle agglutination method for HIV antibody detection: Comparison with conventional rapid HIV tests.

We present the results of the feasibility and preliminary studies on analytical performance of a rapid test for detection of human immunodeficiency virus (HIV) antibodies in human serum or plasma that is an important advance in detecting HIV infection. Current methods for rapid testing of antibodies against HIV are qualitative and exhibit poor sensitivity (limit of detection). In this paper, we describe an ultrasound particle agglutination (UPA) method that leads to a significant increase of the sensitivity of conventional latex agglutination tests for HIV antibody detection in human serum or plasma.
