Tooth derived cells are readily accessible and provide an easy and minimally invasive way to obtain and store stem cells for future use. Banking ones own tooth-derived stem cells is a reasonable and simple alternative to harvesting stem cells from other tissues. Obtaining stem cells from human exfoliated deciduous teeth (SHED) is simple and convenient, with little or no trauma. Every child loses primary teeth, which creates the perfect opportunity to recover and store this convenient source of stem cells--should they be needed to treat future injuries or ailments and presents a far better alternative to simply discarding the teeth or storing them as mementos from the past. Furthermore, using ones own stem cells poses few, if any, risks for developing immune reactions or rejection following transplantation and also eliminates the potential of contracting disease from donor cells. Stem cells can also be recovered from developing wisdom teeth and permanent teeth. Individuals have different opportunities at different stages of their life to bank these valuable cells. It is best to recover stem cells when a child is young and healthy and the cells are strong and proliferative. The purpose of this review is to discuss the present scenario as well as the technical details of tooth banking as related to SHED cells.

Fibrosis accounts for approximately one-third of disease-related deaths globally. Current therapies fail to cure fibrosis, emphasizing the need to identify new antifibrotic approaches. Fibrosis is defined by the excessive accumulation of extracellular matrix (ECM) and resultant stiffening of tissue stroma.

R-loops, three-stranded nucleic acid structures composed of RNA-DNA hybrids, are increasingly recognized as central regulators of genomic stability and transcription. These structures play critical roles across various cellular processes, including DNA replication, repair, and gene regulation, with significant implications for stem cell biology and disease pathogenesis. This review comprehensively explores the molecular underpinnings of R-loop formation, emphasizing the dual nature of R-loops in both facilitating normal cellular functions and contributing to genomic instability.

Polyelectrolyte multilayers (PEMs) based on hyaluronic acid (HA) and poly (diallyldimethylammonium chloride) (PDDA) were deposited on oxidized polystyrene (PS) via the layer-by-layer (LbL) method. The X-ray photoelectron spectroscopy (XPS) confirmed the PEM deposition on PS, and atomic force microscopy (AFM) indicated that the surface roughness of PS also increased after PEM deposition. The PEMs significantly enhanced PS wettability, reducing the contact angle from 73° on PS to 24° on PDDA-terminated (PDDA/HA) PEM (2.

Hepatocellular carcinoma (HCC) is one of the most lethal malignancies worldwide and the most common form of liver cancer. Despite global efforts toward early diagnosis and effective treatments, HCC is often diagnosed at advanced stages, where conventional therapies frequently lead to resistance and/or high recurrence rates. Therefore, novel biomarkers and promising medications are urgently required.

Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.
