Article Abstract

Improving methods for human embryonic stem cell differentiation represents a challenge in modern regenerative medicine research. Using drug repurposing approaches, we discover small molecules that regulate the formation of definitive endoderm. Among them are inhibitors of known processes involved in endoderm differentiation (mTOR, PI3K, and JNK pathways) and a new compound, with an unknown mechanism of action, capable of inducing endoderm formation in the absence of growth factors in the media. Optimization of the classical protocol by inclusion of this compound achieves the same differentiation efficiency with a 90% cost reduction. The presented in silico procedure for candidate molecule selection has broad potential for improving stem cell differentiation protocols.

Introduction: Allogeneic hematopoietic stem-cell transplantation (allo-HSCT) requires reliable vascular access for medication, transfusion, and blood sampling, which often involves painful venipuncture. This prospective study evaluated a novel dual peripherally inserted central venous catheter (PICC) technique to reduce venipuncture frequency in allo-HSCT recipients.

Methods: The study enrolled 29 allo-HSCT recipients.

Wound healing is a dynamic and complex process that consists of four interconnected phases: hemostasis, inflammation, proliferation, and remodeling. This complex process is based on the coordinated actions of growth factors, cytokines, and other cellular interactions. However, conditions such as diabetes and chronic illnesses can disrupt this process and lead to nonhealing wounds or chronic ulcers.

Background: Neurotraumatic conditions, such as spinal cord injury, brain injury, and neurodegenerative conditions, such as amyotrophic lateral sclerosis, pose a challenge to the field of rehabilitation for its complexity and nuances in management. For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge.

This review analyzes Russian and international literature on the treatment of bilateral limbal stem cell deficiency (LSCD), focusing on the use of Simple Oral Mucosal Epithelial Transplantation (SOMET) as a surgical method for restoring the ocular surface. Contemporary sources report 64 cases of SOMET used in the treatment of bilateral LSCD: 35 cases of chemical burns, 16 of thermal burns, 7 cases of Stevens-Johnson syndrome, 1 keratitis, 1 cicatricial pemphigoid, 1 dermoid, 1 case of drug-induced LSCD (mitomycin C), etc. Notably, all transplantations resulted in complete epithelialization, and in 3 cases, penetrating keratoplasty was subsequently performed with favorable functional and anatomical outcomes.

The rise in cancer patients could lead to an increase in intensive care units (ICUs) admissions. We explored differences in treatment practices and outcomes of invasive therapies between patients with sepsis with and without cancer. Adults from 2008 to 2019 admitted to the ICU for sepsis were extracted from the databases MIMIC-IV and eICU-CRD.
