Introduction: Published data obtained from in vitro and in vivo studies was reviewed systematically and analyzed critically to evaluate the effect of oral cavity-derived stem cells (OCDSCs) on the recovery or therapy of neurodegenerative diseases (NDs), such as Alzheimer disease (AD), amyotrophic lateral sclerosis (ALS), Huntington (HD) diseases, and Parkinson disease (PD).

Methods: An electronic search was accomplished. References of included articles were also manually searched.

Objective: The aim of this study was to adapt the Prolonged Grief Disorder - Caregiver Form (PG-12), which is used to measure grief symptoms of caregivers providing care to their relatives with a chronic diseases that cause functional disability to Turkish and to investigate its psychometric properties. We also aimed to investigate the prevalence of prolonged grief disorder in the caregiver sample.

Method: The sample consisted of 120 adult participants (70.

By activating the stress system, stress modulates various physiological parameters including food intake, energy consumption, and, consequently, body weight. The role of oxytocin in the regulation of stress and obesity cannot be disregarded. Based on these findings, we aimed to investigate the effect of intranasal oxytocin on stress response in high-fat-diet (HFD)--fed and control-diet-fed rats exposed to chronic stress.

Here, we describe an induced pluripotent stem cell (iPSC) line that was derived from fibroblasts obtained from a monogenic Parkinson's disease (PD) patient. The disease was caused by a c.634-636delGCC mutation in the PARK7 gene leading to p.

Background: Gaucher disease is a common lysosomal storage disease caused by the deficiency of the β-glucosidase enzyme, leading to sphingolipid accumulation in the reticuloendothelial system in Gaucher cells. Clinical findings are quite variable and some patients may remain asymptomatic lifelong. However, even when patients have mild symptoms, there is a significant increase in their quality of life with enzyme replacement therapy.

Introduction: Vitamin D3 plays an important role in the mineralization mechanism and is often deficient in diabetic patients. The objective of this study was to investigate the odonto/osteogenic differentiation potential of the combination of mineral trioxide aggregate (MTA)/1α,25-dihydroxyvitamin D3 (VD3) on dental pulp stem cells (DPSCs) of patients with type 1 diabetes mellitus (T1DM).

Methods: DPSCs isolated from donors (control and T1DM) were cultured and characterized.

Article Synopsis
  • In 2008, guidelines were established for researching autophagy, which has since gained significant interest and new technologies, necessitating regular updates to monitoring methods across various organisms.
  • The new guidelines emphasize selecting appropriate techniques to evaluate autophagy while noting that no single method suits all situations; thus, a combination of methods is encouraged.
  • The document highlights that key proteins involved in autophagy also impact other cellular processes, suggesting genetic studies should focus on multiple autophagy-related genes to fully understand these pathways.

Background: Autosomal Recessive Congenital Ichthyosis (ARCI) is a group of epidermal keratinization disorders. One of the disease-associated proteins, patatin-like phospholipase domain-containing protein-1 (PNPLA1), plays a key role in the epidermal omega-O-acylceramide synthesis and localizes on the surface of lipid droplets (LDs).

Objective: Previously, routine clinical test results showed abnormal LD accumulation in blood smear samples of our ARCI patients with PNPLA1 mutations.

Lipids are essential building blocks synthesized by complex molecular pathways and deposited as lipid droplets (LDs) in cells. LDs are evolutionary conserved organelles found in almost all organisms, from bacteria to mammals. They are composed of a hydrophobic neutral lipid core surrounding by a phospholipid monolayer membrane with various decorating proteins.
