Differentiating Engineered Tissue Images and Experimental Factors to Classify Cardiomyocyte Content.

In this study, we used machine learning (ML) to classify the cardiomyocyte (CM) content on day 10 of the differentiation of human-induced pluripotent stem cell (hiPSC)-laden microspheroids using easily acquirable nondestructive phase-contrast images taken in the middle of differentiation and tunable experimental parameters. Scale-up suspension culture, use of engineered tissues to support stem cell differentiation, and CM production for improved control over cellular microenvironment in the suspension system need nondestructive methods to track engineered tissue development. The ability to couple images that capture experimenter perceived "good" or "bad" batches based on visualization at early differentiation time points with actual experimental outcomes in an unbiased way is a step toward building these methods.

Astaxanthin engages the l-arginine/NO/cGMP/KATP channel signaling pathway toward antinociceptive effects.

One of the main functions of the sensory system in our body is to maintain somatosensory homeostasis. Recent reports have led to a significant advance in our understanding of pain signaling mechanisms; however, the exact mechanisms of pain transmission have remained unclear. There is an urgent need to reveal the precise signaling mediators of pain to provide alternative therapeutic agents with more efficacy and fewer side effects.

Prediction of Human Induced Pluripotent Stem Cell Cardiac Differentiation Outcome by Multifactorial Process Modeling.

Human cardiomyocytes (CMs) have potential for use in therapeutic cell therapy and high-throughput drug screening. Because of the inability to expand adult CMs, their large-scale production from human pluripotent stem cells (hPSC) has been suggested. Significant improvements have been made in understanding directed differentiation processes of CMs from hPSCs and their suspension culture-based production at chemically defined conditions.

Prevalence of HIV-1 pre-treatment drug resistance in a southern province of Iran, 2016-2017.

HIV-1 transmitted drug resistance (TDR) occurs when primary viruses bear drug resistance mutations (DRMs). TDR causes first-line antiretroviral (ARV) therapy (ART) failure and is becoming more pronounced due to the widespread use of ART. With the absence of routine individual-level drug resistance testing, the World Health Organization (WHO) recommends the tracking of TDR mutations and optimizing the first-line ART following pre-treatment drug resistance (PDR) surveys.
