Objective. The objective of this review is to evaluate the recent treatment and study trends of complementary and alternative medicine (CAM) treatments on muscular atrophy by reviewing in vivo/in vitro studies.Materials and Methods. The searches were conducted via electronic databases including PubMed, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang MED, and five Korean databases. Only in vivo and in vitro studies were included in this study.Results. A total of 44 studies (27 in vivo studies, 8 in vitro studies, and 9 in vivo with in vitro) were included. No serious maternal or fetal complications occurred. There were various animal models induced with muscular atrophy through “hindlimb suspension”, “nerve damage”, ‘alcohol or dexamethasone treatment’, “diabetes”, “CKD”, “stroke”, “cancer”, “genetic modification”, etc. In 28 of 36 articles measuring muscle mass, CAM significantly increased the mass. Additionally, 10 of them showed significant improvement in muscle function. In most in vitro studies, significant increases in both the diameter of myotubes and muscle cell numbers were reported. The mechanisms of action of protein synthesis, degradation, autophagy, and apoptotic markers were also investigated.Conclusions. These results demonstrate that CAM could prevent muscular atrophy. Further studies about CAM on muscular atrophy are needed.

Background: The therapeutic value of mesenchymal stem cells (MSCs) in tissue engineering and regenerative medicine is attributable in part to paracrine pathways triggered by several secreted factors secreted into culture media. The secreted factor here is known as the conditioned medium (CM) or secretome. Objectives: This review is aimed to investigate and summarise the in-vitro, pre-clinical in-vivo studies regarding the role of CM-MSC in ligament or tendon healing from 1998 until 2018. Data Sources: A systematic literature search on PubMed, MEDLINE, OVID, Scopus, Google scholar, and Cochrane library was carried out by using search terms: Secretome, conditioned medium, mesenchymal stem cell, ligament, tendon and healing. Methods: A total of 904 articles were reviewed. Five articles were identified as relevant for this systematic literature review. Results: One tables of studies were constructed for in vitro studies and in-vivo studies. Conclusion: All of the included in-vitro studies and in-vivo studies have shown a promoting effect of ligament or tendon healing at various stages in vitro or in vivo. Although there are no clinical studies regarding the use of CM- MSC in the human ligament or tendon healing that have been conducted, transplantation of secretome has shown a promising result in the acceleration of ligament or tendon healing process.

This systematic review evaluated the transplantation of cells derived from adipose tissue for applications in dentistry. SCOPUS, PUBMED and LILACS databases were searched for in vitro studies and pre-clinical animal model studies using the keywords “ADIPOSE”, “CELLS”, and “PERIODONTAL”, with the Boolean operator “AND”. A total of 160 titles and abstracts were identified, and 29 publications met the inclusion criteria, 14 in vitro and 15 in vivo studies. In vitro studies demonstrated that adipose- derived cells stimulate neovascularization, have osteogenic and odontogenic potential; besides adhesion, proliferation and differentiation on probable cell carriers. Preclinical studies described improvement of bone and periodontal healing with the association of adipose-derived cells and the carrier materials tested: Platelet Rich Plasma, Fibrin, Collagen and Synthetic polymer. There is evidence from the current in vitro and in vivo data indicating that adipose-derived cells may contribute to bone and periodontal regeneration. The small quantity of studies and the large variation on study designs, from animal models, cell sources and defect morphology, did not favor a meta-analysis. Additional studies need to be conducted to investigate the regeneration variability and the mechanisms of cell participation in the processes. An overview of animal models, cell sources, and scaffolds, as well as new perspectives are provided for future bone and periodontal regeneration study designs.

Abstract Background Over the past few decades, the popularity of complementary and alternative medicine (CAM) has grown considerably and along with it, scrutiny regarding its evidence base. While this is to be expected, and is in line with other health disciplines, research in CAM is confronted by numerous obstacles. This scoping review aims to identify and report the strategies implemented to address barriers to the conduct and application of research in CAM. Methods The scoping review was undertaken using the Arksey and O’Malley framework. The search was conducted using MEDLINE, EMBASE, EMCARE, ERIC, Scopus, Web of Science, The Cochrane Library, JBI and the grey literature. Two reviewers independently screened the records, following which data extraction was completed for the included studies. Descriptive synthesis was used to summarise the data. Results Of the 7945 records identified, 15 studies met the inclusion criteria. Using the oBSTACLES instrument as a framework, the included studies reported diverse strategies to address barriers to the conduct and application of research in CAM. All included studies reported the use of educational strategies and collaborative initiatives with CAM stakeholders, including targeted funding, to address a range of barriers. Conclusions While the importance of addressing barriers to the conduct and application of research in CAM has been recognised, to date, much of the focus has been limited to initiatives originating from a handful of jurisdictions, for a small group of CAM disciplines, and addressing few barriers. Myriad barriers continue to persist, which will require concerted effort and collaboration across a range of CAM stakeholders and across multiple sectors. Further research can contribute to the evidence base on how best to address these barriers to promote the conduct and application of research in CAM.

For studying heparin effect on blood coagulation and on inhibitors, the drug was added at increasing amounts to a normal platelet poor plasma (PPP), and to plasmas of patients with variable amounts of clotting factors (cirrhotic, pregnant, etc) -IN VITRO STUDIES-, and infused to the same individuals -IN VIVO STUDIES-. Modifications on two clotting assays (KCCT-TT) were compared to heparin potentiating effect on AntiXa (Denson & Bonnar tech).When studied IN VITRO, the sensibility of KCCT, TT, and AntiXa techniques for heparin measurement was similar. IN VIVO, an apparently greater sensibility using AntiXa technique was observed.For determining if this phenomena was related to a specific enhanced potentiating effect of the inhibitor against Xa, exerted by heparin IN VIVO, experiences were repeated IN VITRO and IN VIVO, measuring heparin effect on KCCT, TT, and on the inhibitor, studied against Xa and thrombin. A personal technique was used for the measurement of Antithrombin III heparin potentiating effect, using diluted platelet poor test plasma, heated (56°C 15’) and incubated with thrombin during a fixed time, and reading residual thrombin on citrated human PPP. IN VITRO, all techniques were similar in their ability to show heparin presence.IN VIVO, the potentiating effect of heparin on the inhibitor, measured against Xa or thrombin, was greater than the changes obtained on KCCT or TT.So, AntiXa-Antithrombin III techniques seem to be more sensitive for heparin measurement IN VIVO.This “dissociation” of results in between the potentiating effect on the inhibitor, that is not simultaneously exerted on global coagulation, is interpreted as a heparin pro-coagulant effect, exerted by the drug IN VIVO.

Diameter Change

In vitro studies of abdominal aortic aneurysm (AAA) have been widely reported. Frequently mock artery models with intraluminal thrombus (ILT) analogs are used to mimic the in vivo AAA. While the models used may be physiological, their properties are frequently either not reported or investigated. This study is concerned with the testing and characterization of previously used vessel analog materials and the development of new materials for the manufacture of AAA models. These materials were used in conjunction with a previously validated injection molding technique to manufacture AAA models of ideal geometry. To determine the model properties (stiffness (β) and compliance), the diameter change of each AAA model was investigated under incrementally increasing internal pressures and compared with published in vivo studies to determine if the models behaved physiologically. A FEA study was implemented to determine if the pressure-diameter change behavior of the models could be predicted numerically. ILT analogs were also manufactured and characterized. Ideal models were manufactured with ILT analog internal to the aneurysm region, and the effect of the ILT analog on the model compliance and stiffness was investigated. The wall materials had similar properties (Einit 2.22 MPa and 1.57 MPa) to aortic tissue at physiological pressures (1.8 MPa (from literature)). ILT analogs had a similar Young’s modulus (0.24 MPa and 0.33 MPa) to the medial layer of ILT (0.28 MPa (from literature)). All models had aneurysm sac compliance (2.62–8.01×10−4/mm Hg) in the physiological range (1.8–9.4×10−4/mm Hg (from literature)). The necks of the AAA models had similar stiffness (20.44–29.83) to healthy aortas (17.5±5.5 (from literature)). Good agreement was seen between the diameter changes due to pressurization in the experimental and FEA wall models with a maximum difference of 7.3% at 120 mm Hg. It was also determined that the inclusion of ILT analog in the sac of the models could have an effect on the compliance of the model neck. Ideal AAA models with physiological properties were manufactured. The behavior of these models due to pressurization was predicted using finite element analysis, validating this technique for the future design of realistic physiological AAA models. Addition of ILT analogs in the aneurysm sac was shown to affect neck behavior. This could have implications for endovascular AAA repair due to the importance of the neck for stent-graft fixation.

Axial Forces

Our aim was to measure axial forces in the stomach and to evaluate their relation to circumferential contractions of the gastric walls and the emptying of gastric content. We used a combination of simultaneous radioscintigraphy, gastroduodenal manometry, and an axial force transducer with an inflatable 2-ml balloon fluoroscopically placed in the antrum. In vitro studies demonstrated that the axial force transducer records only antegrade forces along the longitudinal axis of this probe in an intensity-dependent manner. In vivo studies were performed in five healthy subjects for at least 3 h after ingestion of radiolabeled meals. When administered separately, the emptying of liquids or solids from the stomach is associated with generation of antral axial forces and coincident phasic pressure activity; however, almost 20% (average) of gastric axial forces during emptying of liquids or solids are unassociated with proximal or distal antral pressure activity ("isolated" forces). High amplitude antral axial forces and pressures occur during both lag and postlag emptying phases. During emptying of liquids, there is a trend for axial forces to be coincident more often with proximal than with distal antral pressure activity and vice versa for the emptying of solids (P = 0.015). These data suggest that when placed in the antrum, the transducer can semiquantitatively record axial forces during gastric emptying. By combining these observations with the data from in vitro studies, it appears that axial forces predominantly result from traction on the balloon by the longitudinal vector resulting from circumferential gastric contractions. The combination of radioscintigraphy and measurement of antral axial forces is a promising method to evaluate mechanical forces involved in the emptying of the human stomach.

AbstractBrazilian health care programs recommend the use of cariostatic solutions of silver diamine fluoride (SDF) or sodium fluoride varnishes for children 0 to 3 years old with high or moderate caries activity for the control of caries lesions. SDF is a safe, economical, efficient and non-invasive coadjuvant agent, exerting an antibacterial action capable of reducing superficial mineral loss of the enamel and can be used in the treatment of deciduous and permanent teeth. The objective of this literature review was to gather current information on describing the mechanism of SDF action’ and its clinical application in young children in caries prevention and paralysis. The PubMed / Medline and Cochrane Library databases were accessed by identifying the relevant studies published in English from 1960 to May 2017. The search strategy employed the keywords: “Silver diamine fluoride” and “Children “or “Infant” and “Caries prevention”. Data extraction was performed in: 19 in vitro studies; 10 review articles and 8 in vivo studies. It was possible to conclude that SDF is almost twice as effective compared to fluoride varnish in caries paralysis. However, the contact time of the solution and the optimal frequency of application of the SDF are still undefined, inducing new projects and clinical studies in the search for an adequate clinical protocol of this cariostatic.Keywords: Preventive Dentistry. Children. Dental Caries.Resumo Os programas de assistência à saúde brasileiros recomendam para o controle das lesões de cárie a utilização de soluções cariostáticas de diamino fluoreto de prata - DFP ou vernizes de fluoreto de sódio para crianças de 0 a 3 anos com atividade de cárie alta ou moderada. O DFP é agente coadjuvante seguro, econômico, eficiente e não invasivo, exercendo ação antibacteriana capaz de reduzir a perda mineral superficial do esmalte e, pode ser utilizado no tratamento de dentes decíduos e permanentes. O objetivo desta revisão de literatura foi reunir informações atuais sobre descrever o mecanismo de ação do DFP e sua aplicação clínica em crianças de pouca idade na prevenção e paralisação da cárie. As bases de dados PubMed/Medline e Cochane Library foram acessadas identificando os estudos relevantes publicados em inglês, no período de 1960 a maio de 2017. A estratégia de busca empregou as palavras-chave: “Silver diamine fluoride” and “Children” or “Infant” and “Caries prevention”. A extração dos dados foi realizada em: 19 estudos in vitro; 10 artigos de revisão e 8 estudos in vivo. Foi possível concluir que o DFP apresenta-se quase duas vezes tão eficaz comparado ao verniz fluoretado na paralização de cárie. Porém, o tempo de contato da solução e a frequência ótima de aplicação do DFP ainda estão indefinidos, suscitando novos projetos e estudos clínicos na busca de adequado protocolo clínico deste cariostático.Palavra-chave: Odontologia Preventiva.
