Due to the existence of a wide variety of products and the constant advancement in the development and dissemination of new technologies. These materials are applied in different engineering solutions, highlighting the possibility of using recyclable and biodegradable materials and executing geotechnical and environmental works ranging from the control of erosion to the protection of groundwater. In this context, this work presents a literature review on the use of recyclable and biodegradable materials as geosynthetic products, as well as their association with traditional geosynthetics for solutions in engineering works. The review was carried out through the platforms Google Scholar and Portal of Journals of CAPES, using keywords and Boolean connectors as descriptors. It is observed that there is a potential for the use of recyclable and biodegradable materials as geosynthetics. However, there is still a need for a careful assessment concerning the benefits, limitations, and impacts caused by the use of these wastes.","PeriodicalId":103143,"journal":{"name":"JOURNAL OF BIOENGINEERING AND TECHNOLOGY APPLIED TO HEALTH","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116702397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technology can be applied to regenerative medicine and tissue engineering to treat diseases, test pharmaceuticals, and study the mechanisms underlying diseases. Currently, there are three basic types of 3D bioprinting technologies: laser, droplet, and extrusion. Laser-based bioprinters (LBP) use laser energy to induce the bioink transfer. Droplet-based bioprinters (DBP) expel the bioink dropwise throughout a nozzle. Inkjet-based bioprinters are the DBP commonly used for biological proposes, it is also a non-contact approach that releases controlled volumes of bioink drops in a continuous (CIJ) or under demand way (DOD). The extrusion-based bioprinters (EBB) also use pressure to force out the bioink, but consists of a syringe containing the material with a pneumatic or mechanical mechanism as dispensing system. Comparing to the other bioprinting technologies, extrusion printing is the most versatile and is indicated for bioprinting of scaffold prosthetic implants. The bioinks used in 3D bioprinting are composed of a solution with a biomaterial mixture, usually encapsulating cells. Biomaterials are essential components of 3D bioprinting technologies because they provide scaffolds as supporting physical structures for cells to attach, grow, differentiate, and develop into tissues. Numerous cell types have been used in 3D bioprinting to build cardiovascular, musculoskeletal, neural, hepatic, adipose and skin tissues. Bioprinting is an emerging technology that has the ability to revolutionize the way we address many health issues.","PeriodicalId":103143,"journal":{"name":"JOURNAL OF BIOENGINEERING AND TECHNOLOGY APPLIED TO HEALTH","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130307847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tissue bioengineering may be an alternative approach for bone regeneration. Here we investigated the osteogenic potential of dental pulp stem cells from deciduous teeth (DPSC) in association with a Ricinus bone compound (RBC) in a model of bone defect. The influence of the biomaterial RBC on the proliferation and osteogenic differentiation of DPSC was assessed in vitro by MTT metabolism and alizarin red staining, respectively. The morphologic analysis was performed using the optic and scanning electron (SEM) microscopies. For the in vivo study, 54 Wistar rats submitted to calvarial defects were filled with RBC or RBC+DPSC. A control group had the defects filled only with blood clots. Analyses were performed 15, 30 and 60 days after treatment using digital radiography, optical microscopy, SEM and chemical analysis by electron dispersive spectroscopy. The Ricinus bone compound (RBC) did not inhibit the osteogenic differentiation in vitro. No spontaneous regeneration was observed in the control group. The area of the calvarial defect of the RBC+DPSC group showed greater radiopacity on day 15. The RBC presented no reabsorption, was biocompatible and showed osteointegration, working as a mechanical filling. Only sparse ossification areas were found and those were larger and more developed on the RBC+DPSC group when compared to animals treated only with RBC. RBC in association with DPSC is a promising combination for applications in bone regeneration. \u0000 ","PeriodicalId":103143,"journal":{"name":"JOURNAL OF BIOENGINEERING AND TECHNOLOGY APPLIED TO HEALTH","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114297977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has the purpose of improving technical characteristics and reducing environmental impact through the use of sustainable raw materials such as natural fibers and other fibers from industrial waste. In this sense, the objective of this work was to study and compare the mechanical properties of polyester composites (PL) reinforced with natural sisal fiber and residues of polyethylene terephthalate (PET) synthetic fibers. Initially, we evaluated the moisture and morphology of the fibers. The composites with PL matrix were obtained and the fiber concentration varied by 1%, 3%, and 5% by weight. In the composites, the mechanical properties under flexion and impact resistance were evaluated. We concluded that the level of reinforcement with sisal fibers did not significantly affect the mechanical properties. However, the PET fiber provided significant improvements in the properties of the composite. Thus, the composites reinforced with PET fiber residue have advantages in the development of new material with sustainable characteristics. \u0000 ","PeriodicalId":103143,"journal":{"name":"JOURNAL OF BIOENGINEERING AND TECHNOLOGY APPLIED TO HEALTH","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125714095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
