Abstract
AbstractPlants are the source of a large spectrum of phytochemicals, and the combined and concerted action of biologically active compounds lead to the potential beneficial properties of each plant matrix. A great attention is being addressed over the years toward herbs and medicinal plants. Dragon’s Blood is a reddish resin oil extracted from Croton lechleri tree. It has been extensively used by indigenous cultures of the Amazon River since ancient times due to the beneficial nutraceutical and pharmaceutical properties. This perspective aims at providing a current framework on Dragon’s Blood with focus on antioxidant properties for nutraceuticals and pharmaceuticals in a novelty integrated and multidisciplinary manner, highlighting the current knowledge, the main research lines, and emerging strategies. A literature quantitative research analysis approach was applied as starting point. The literature search was carried out by means of the Scopus database; 365 documents have been retrieved in the year range from 1854 to 2021, and a total of 269 terms were identified. Among the top-recurring keywords appear: unclassified drug, nonhuman, plant extract/s, Dragon’s Blood, dracaena, Dragon Blood, chemistry, human, animal/s, plant resin. Source, chemical composition, potential nutraceutical, and therapeutical applications of Dragon’s Blood are discussed here. The anti-inflammatory, wound healing, antidiarrheals, anticancer, antirheumatic, antiseptic, and antioxidant activities identified in the Dragon’s Blood extracts can open novel perspectives for its use in food and pharmaceutical industries. While different bioactive compounds have already been identified in Dragon’s Blood extract, only a few studies can be found in literature.

Abstract
Science and commerce advance together and the stem cell field is no exception. With the promise of cures for conditions as diverse as cancer, autism, neural degeneration, organ replacement and addiction, long-term preservation of dental stem cells is a growth market. The discovery nearly twenty years ago, of viable, multipotent, stem cells in dental pulp from both baby and adult teeth initiated, and drives, this market.The dental stem cell preservation services, "tooth banks", focus on the collection of a child's baby teeth, as they are shed naturally, and storage of the stem cells from within the pulp for therapeutic use in later years should the child require them. This review focuses on the procedures related to these stem cell storage services and may serve as an introduction for many to the practice of "tooth banking".

Abstract
Creatine acts intracellularly as energy buffer and storage, demonstrating protective effects in animal models of neurodegenerative diseases. However, its permeability throught blood-brain barrier (BBB) is reduced. The aim of the present study was developing a carrier to facilitate the delivery of creatine to the central nervous system. Creatine nanoliposomes were produced, characterized and assayed in models of toxicity in vitro and in vivo. Particles showed negative zeta potential (-12,5 mV), polydispersity index 0.237 and medium-size of 105 nm, which was confirmed by transmission electron microscopy (TEM) images. Toxicity assay in vitro was evaluated with blank liposomes (no drug) or creatine nanoliposomes at concentrations of 0.02 and 0.2 mg/mL, that did not influence the viability of Vero cells. The result. of the comet assay that the nanoliposomes are not genotoxic, togeher with cell viability demonstrated that the nanoliposomes are not toxic. Besides, in vivo assays not demonstrate toxicity in hematological and biochemical markers of young rats. Nevertheless, increase content of creatine in the cerebral cortex tissue after subchronic treatment was observed. Altogether, results indicate increase permeability of creatine to the BBB that could be used as assay for in vivo studies to confirm improved effect than free creatine.

Adnan S, Lone MM, Khan FR, Hussain SM, Nagi SE. Which is the most recommended medium for the storage and transport of avulsed teeth? A systematic review. Dent Traumatol 2018; 34:59-70. [PMID: 29292570 DOI: 10.1111/edt.12382] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/21/2017] [Indexed: 11/29/2022]
Abstract
BACKGROUND/AIMS A wide variety of materials has been researched for their use as potential storage media for avulsed teeth, but it is essential to recognize the medium most recommended for improvement of the prognosis of avulsed teeth. The aim of this systematic review was to identify the most recommended medium to store and transport avulsed teeth based on the survival of periodontal ligament (PDL) cells as determined by in vitro studies. METHODS Only laboratory-based experimental studies on PDL cells found on adult permanent teeth were included. Data were collected using PubMed, CINAHL plus (EBSCO host), and the Cochrane Library, along with Google Scholar and a hand search. The key terms employed were permutations of [avulsed permanent teeth* OR dental avulsion* OR knocked out teeth*] AND [storage media* OR transport media* OR biological transport* OR PDL cell viability* OR PDL cell survival*]. A customized data extraction pro forma was used to extract the data and to evaluate the quality and risk of bias. RESULTS The initial search yielded 978 articles, but only 67 were selected. Milk was the most recommended individual medium followed by Hank's balanced salt solution. Among natural products other than milk, propolis and coconut water were most frequently recommended. Recommendations were based on maintenance of PDL cell viability followed by ease of availability, low cost, and long shelf life. CONCLUSIONS Natural products are more effective in maintaining the PDL cell viability compared to synthetic products. Some storage media recommendations were also based upon practical aspects. Although natural products other than milk have more recommendations as a group, milk is the most recommended storage medium individually, based not only on PDL cell viability, but also practical considerations.
