Tissue engineering approaches for dental pulp regeneration:The development of novel bioactive materials using pharmacological epigenetic inhibitors

The drive for minimally invasive endodontic treatment strategies has shifted focus from technically complex and destructive root canal treatments towards more conservative vital pulp treatment.However,novel approaches to maintaining dental pulp vitality after disease or trauma will require the development of innovative,biologicallydriven regenerative medicine strategies.For example,cell-homing and cell-based therapies have recently been developed in vitro and trialled in preclinical models to study dental pulp regeneration.These approaches utilise natural and synthetic scaffolds that can deliver a range of bioactive pharmacological epigenetic modulators(HDACis,DNMTis,and ncRNAs),which are cost-effective and easily applied to stimulate pulp tissue regrowth.Unfortunately,many biological factors hinder the clinical development of regenerative therapies,including a lack of blood supply and poor infection control in the necrotic root canal system.Additional challenges include a need for clinically relevant models and manufacturing challenges such as scalability,cost concerns,and regulatory issues.This review will describe the current state of bioactive-biomaterial/scaffold-based engineering strategies to stimulate dentine-pulp regeneration,explicitly focusing on epigenetic modulators and therapeutic pharmacological inhibition.It will highlight the components of dental pulp regenerative approaches,describe their current limitations,and offer suggestions for the effective translation of novel epigenetic-laden bioactive materials for innovative therapeutics.

Antioxidant Activity of 50 Traditional Chinese Medicinal Materials Varies with Total Phenolics

This study was designed to determine the total phenolic content of 50 herbs and to examine their antioxidant potential. In the sample preparation, 60% ethanol was chosen as the extraction solvent for the subsequent experiments. Folin-Cicolteau phenol reagent and a colorimetric method were used to determine the total phenolic content of the selected herbs. The result showed that total phenolic content of those herbs ranged from 2 to 185 mg/g. In antioxidant assay, the ferric reducing/antioxidant power (FRAP) values ranged from 2 to 134 mg GAE/g;the IC50 values of DPPH?·, ·OH and ?scavenging were in the range of 0.06 - 5.50 mg/mL, 0.017 - 0.636 mg/mL and 0.050 - 0.681 mg/mL respectively. Flos caryophylli was the exceptant in the ?scavenging assay because there was no linear relation between the concentration and the scavenging percentage. Compared to gallic acid, ascorbic acid and butylated hydroxytoluene (BHT) in antioxidant assay as positive control, the most potential antioxidant herbs were Cacumen platycladi, Radix et Rhizoma rhei, Rhizoma rhodiolae crenulatae, and Rhizoma sanguisorbae with considerable content of phenolics. Especially, a positive and significant correlation was found between the total phenolic content and FRAP value or DPPH· scavenging percentage.

Samples of the Collection of Old Medicine Raw Materials of the Department of Pharmacognosy of St.Petersburg Chemical Pharmaceutical University,Which Can Be Used in Food

In the world there are many collections of the pharmaceutical trend.In America,the exhibits of this profile are in the Smithsonian Museum of Natural History in Washington,in Europe these are collections of pharmacy museums in Heidelberg(Germany),Krakow and Warsaw(Poland),Basel(Switzerland),Riga(Latvia),and others.Some of them have many thousands of exhibits.There are also separate collections of pharmaceutical items for educational institutions,for example,a collection of old medicinal raw materials in Vigan’s Cabinet,Queen College,Cambridge(Great Britain).All these meetings,however,have long been known and described in detail.Most of them do not have a strict orientation and are presented,along with old medicinal raw materials,as well as tools and appliances,dishes,books,herbaria and various auxiliary items.All the more interesting is the collection indicated in the title of the article,which arose literally from non-existence.She was transferred to the educational institution at its creation,and this year she,like him,turns a hundred years old.It has a strict focus and is represented almost exclusively by medicinal raw materials.Studying the samples of this old collection,as a whole of medical profile,makes it possible to understand that many plants,which initially had only food use,gradually became pharmaceutical objects.Probably,it was the long practice of food use,with the fixing of associated pharmacological effects in the memory,that became the reason for choosing certain types of raw materials as medicinal.Ordinary foods,protein and starchy,began to be perceived as strengthening,mucous—as enveloping and anti-ulcer,some fruits and herbs—as antiscorbutic,sharp—as appetizing and improving the work of the stomach,and so on.

3D bioprinting of collagen-based materials for oral medicine

Oral diseases have emerged as one of the leading public health challenges globally.Although the existing clinical modalities for restoration of dental tissue loss and craniomaxillofacial injuries can achieve satisfactory therapeutic results,they cannot fully restore the original complex anatomical structure and physiological function of the tissue.3D printing of biological tissues has gained growing interest in the field of oral medicine with the ability to control the bioink component and printing structure for spatially heterogeneous repairing constructs,holding enormous promise for the precise treatment of oral disease.Particularly,collagen-based materials have been recognized as promising biogenic bioinks for the regeneration of several tissues with high cell-activating and biocompatible properties.In this review,we summarize 3D printing methods for collagen-based biomaterials and their mechanisms.Additionally,we highlight the animal sources of collagen and their characteristics,as well as the methods of collagen extraction.Furthermore,this review provides an overview of the 3D bioprinting technology for the regeneration of the pulpal nerve and blood vessels,cartilage,and periodontal tissue.We envision that this technique opens up immense opportunities over the conventional ones,with high replicability and customized function,which can ultimately promote effective oral tissue regeneration.

Heavy Metal Accumulation in Medicinal Plants Collected from Environmentally Different Sites

Objective To estimate the heavy metal content in soil and selected medicinal plants procured from environmentally different sites of the same city. Methods Soil and plant samples of Abutilon indicum, Calotropis procera, Euphorbia hirta, Peristrophe bycaliculata, and Tinospora cordifolia were collected from 3 environmentally different sites of the city： heavy traffic area （HTA）, industrial area （IA）, and residential area （RA）. Pb by inductively coupled plasma emission spectrometry and compared Cd, Cr, and Ni were estimated in soil and plant samples Results The level of heavy metal was higher in soil than in plant parts studied. Accumulation of heavy metals varied from plant to plant. Pb was the highest in Calotropis procera root from HTA site and the lowest in Peristrophe bycaliculata whole plant from IA site. It was also lower in residential area than in heavy traffic area. Conclusion The level of heavy metal content differed in the same medicinal plant collected from environmentally different sites of the same city. Thus, it reiterates our belief that every medicinal plant sample should be tested for contaminant load before processing it further for medication.
