Autologous chondrocyte (CH) transplantation is a novel strategy to treat post-traumatic osteoarthritis (PTOA). In this study, an in vitro coculture model was used to explore the effects of interleukin (IL)-10 overexpressed CHs on degenerated CHs. The original CHs were isolated from the patients' knee joint cartilage and pretreated with IL-1β to get degenerated CHs. Moreoer, CHs were transfected with a lentivirus vector to overexpress IL-10. After coculture with the degenerated CHs, the apoptosis, collagen X, IL-6, and TNF-α of original CHs were increased, and the collagen II and IL-10 were decreased compared to the separated culture condition. Coculture with original CHs did not alleviate the degeneration of the IL-1β-pretreated CHs. However, coculture with the IL-10-overexpressed CHs rescued the proliferation, collagen II, aggrecan, SOX9, and IL-10 expression, and suppressed the apoptosis, collagen X, RUnx2, IL-6, and TNF-α levels in the IL-1β pretreated CHs. Additionally, the IL-10-overexpressed CHs also maintained a healthy state when cocultured with the degenerated CHs. Therefore, transplanting the IL-10-overexpressed CHs in the treatment of PTOA would obtain a more durable and visible effect in alleviating the CH degeneration.

Neuropsychological findings in obsessive-compulsive disorder (OCD) are mainly spread around the role of memory and executive functions. However, the outcomes vary across different OCD populations. In addition, the extent to which each of these factors can distinguish patients with OCD (PwOCD) from healthy individuals has been uncertain and of great attention. The present study aimed to discover the above issues.

This was a cross-sectional study of 182 individuals (90 PwOCD and 92 matched healthy controls). After considering inclusion and exclusion criteria, the participants were administered neuropsychological tests including, Wechsler Memory Scale-III (WMS-III), Wisconsin Card Sorting Test (WCST), and Stroop Color-Word Test (SCWT). Using compare mean and regression analysis methods, data were analyzed to test the study hypothesis.

The results demonstrated weaker performance of PwOCD in immediate memory, General memory and working memory as well as response inhibition indexes compared to the control group. Besides, the results showed that General Memory and Reaction Time2 of SCWT indexes could be predictive variables for discriminating PwOCD from the controls.

Findings of this study support the prior assumptions about impaired memory dimensions and response inhibition but not set shifting, among PwOCD. We also present an initial model for the predictive role of these neuropsychological variables in discriminating OCD from healthy individuals and increase diagnostic accuracy.

Compelling evidence has demonstrated that physical activity and exercise can also prevent common mental disorders, such as depression and anxiety disorders, and have multiple beneficial effects on physical and mental health of people with a wide range of mental disorders. This body of evidence has been incorporated in national and international guidelines over the last decades, recommending the inclusion of physical activity and exercise as therapeutic approaches for mental disorders, mainly for depression and schizophrenia. Nonetheless, implementation into clinical practice has been slow, probably due to mental health professionals and patients' barriers. This article aims to provide a brief overview and summary of the evidence on 1) the preventive effects of physical activity for a wide range of mental disorders; 2) the role of physical activity in physical health promotion of people with mental disorders; 3) the role of exercise as a strategy to manage mental health symptoms for a range of mental disorders; and 4) the challenges and barriers faced when implementing exercise in clinical practice.3D microenvironments provide a unique opportunity to investigate the impact of intrinsic mechanical signaling on progenitor cell differentiation. Using a hydrogel-based microwell platform, arrays of 3D, multicellular microtissues in constrained geometries, including toroids and cylinders are produced. These generated distinct mechanical profiles to investigate the impact of geometry and stress on early liver progenitor cell fate using a model liver development system. Image segmentation allows the tracking of individual cell fate and the characterization of distinct patterning of hepatocytic makers to the outer shell of the microtissues, and the exclusion from the inner diameter surface of the toroids. Biliary markers are distributed throughout the interior regions of micropatterned tissues and are increased in toroidal tissues when compared with those in cylindrical tissues. Finite element models of predicted stress distributions, combined with mechanical measurements, demonstrates that intercellular tension correlates with increased hepatocytic fate, while compression correlates with decreased hepatocytic and increased biliary fate. BlasticidinS This system, which integrates microfabrication, imaging, mechanical modeling, and quantitative analysis, demonstrates how microtissue geometry can drive patterning of mechanical stresses that regulate cell differentiation trajectories. This approach may serve as a platform for further investigation of signaling mechanisms in the liver and other developmental systems.Despite significant progress in understanding the disease mechanism of traumatic brain injury (TBI), promising preclinical therapeutics have seldom been translated into successful clinical outcomes, partially because the model animals have physiological and functional differences in the central nervous system (CNS) compared to humans. Human relevant models are thus urgently required. Here, an in vitro mild TBI (mTBI) modeling system is reported based on 3D cultured human induced pluripotent stem cells (iPSC) derived neural progenitor cells (iPSC-NPCs) to evaluate consequences of single and repetitive mTBI using a 3D printed mini weight-drop impact device. Computational simulation is performed to understand the single/cumulative effects of weight-drop impact on the NPC differentiated neurospheres. Experimental results reveal that neurospheres show reactive astrogliosis and glial scar formation after repetitive (10 hits) mild impacts, while no astrocyte activation is found after one or two mild impacts. A 3D co-culture model of human microglia cells with neurospheres is further developed.
