Improved Malignancy of Colon Cancer Cells at Gene Expression Level with Constitutive Activation of the Eukaryotic Elongation Factor 2 (eEF2) Under Nutrition Deficient Conditions.

Regulation of protein production in response to physiological signals is achieved through precise control of Eukaryotic Elongation Factor 2 (eEF2), whose distinct translocase function is crucial for cell survival. Phosphorylation of eEF2 at its Thr56 (T56) residue inactivates this function in translation. Using genetically modified paralogue of a colon cancer cell line, HCT116 which carries a point mutation at Ser595-to-Alanine in the eEF2 gene we were able to create a constitutively active form of eEF2.

Combinational therapy of all-trans retinoic acid (ATRA) and sphingomyelin induces apoptosis and cell cycle arrest in B16F10 melanoma cancer cells.

The apoptotic effect of garlic derived SEVs on different types of cancer cell lines in vitro.

Background/aim: Small extracellular vesicles (SEVs) are known to have an impact on the physiological conditions of target cells, are a critical component of cell-to-cell communication, and have been implicated in a variety of diseases. Although it has been proposed that edible plant-derived nanoparticles have an effect on communication with mammalian cells, the influence of these nanoparticles on cancer cell development has yet to be explored.

Materials And Methods: In order to characterize small extracellular vesicles obtained from garlic, specific SEV surface markers, antibodies, and size detections were identified using scanning electron microscopy and nanoparticle tracking analysis.

Unveiling the potential: Extracellular vesicles from plant cell suspension cultures as a promising source.

Extracellular vesicles are secreted by all eukaryotic cells and they have an important role in intercellular signaling. Plant extracellular vesicles (PEVs) are a novel area of research that has gained attention due to their potential implications in biomolecule transport and therapeutic applications. PEVs are lipid bilayer-enclosed structures that contain a diverse cargo of biomolecules such as proteins and lipids.

Evaluating boron levels in Turkish mineral waters: a comparative study of three analytical techniques.

Turkey is abundant in natural mineral water sources, thanks to its location on the Alpine-Himalayan belt. Natural mineral water is drinking water characterized by its natural mineral, trace elements, and carbon dioxide content. Because of quite insufficient data, the boron content in bottled natural mineral waters in Turkey was analyzed by three different methods and compared: inductively coupled plasma mass spectrometry technique, carminic acid, and azomethine-H methods, in this study.

Dual- or single rinse? The tubular sealer penetration of endodontic chelating agents.

Introduction: In this study, we aimed to compare the effectiveness of various chelating agents, ethilenediaminetetraacetic acid (EDTA), citric acid (CA), and etidronic acid (HEDP) mixed in two different forms, in removing the smear layer and promoting the penetration of an endodontic sealer into the dentinal tubules of extracted single-rooted teeth.

Methods: The study used 75 teeth divided into five groups: 17% EDTA, 10% CA, 9% HEDP + NaOCl, 9% HEDP + distilled water (DW), and a control (DW) group. Scanning electron microscopy was used to assess smear layer removal and confocal laser microscopy was used to evaluate tubular sealer penetration at different depths from the apical tip.

A Perspective on the Characterization of Early Neural Progenitor Cell-Derived Extracellular Vesicles for Targeted Delivery to Neuroblastoma Cells.

As an element of the cellular signaling systems, extracellular vesicles (EVs) exhibit many desirable traits for usage as targeted delivery vehicles. When administered, EVs cause little to no toxic or immune response, stay in circulation for longer periods compared to synthetic carriers, preferentially accumulate in tissues that are the same or similar to their cell-of-origin and can pass through the blood-brain barrier. Combined, these traits make neural EVs a particularly promising tool for delivering drugs to the brain.

Biocompatibility and Cytotoxicity of Pulp-Capping Materials on DPSCs, With Marker mRNA Expressions.

Objectives: The present study aimed to (1) investigate biocompatibility and cytotoxicity of pulp-capping materials on viability of human dental pulp stem cells (hDPSCs); (2) determine angiogenic, odontogenic, and osteogenic marker mRNA expressions; and (3) observe changes in surface morphology of the hDPSCs using scanning electron microscopy (SEM).

Methods: Impacted third molars were used to isolate the hDPSCs, which were treated with extract-release fluids of the pulp-capping materials (Harvard BioCal-Cap, NeoPUTTY MTA, TheraCal LC, and Dycal).
