Therefore, the aim of the present study is to evaluate the influence of current adhesive systems on color, color stability and translucency of resin composites. Methods: Fifty disc-shaped microhybrid resin composite specimens were prepared. Resin composite discs were divided into five groups randomly according to adhesive system including a control group (n=10) (Clearfil Protect Bond, Adper EasyOne, Clearfil QuickBond and Tokuyama BondForce). Color and translucency measurements were performed with a clinical spectrophotometer at baseline, immediately after adhesive system application and after immersion in water for 30 days. For statistical analysis, paired-samples t-test, one-way analysis of variance (ANOVA) and Tukey’s post-hoc comparisons were used (p<0.05). Results: The adhesive application significantly changed the color (E*) of the resin composite discs regardless of the adhesive brand. Storage of the resin composite discs in water for 30 days caused significant color changes in the control group. Significant differences were found in color values of the Adper EasyOne and Clearfil Protect Bond groups after aging. surfaces of the discs were polished with 600-, 800-, 1,200-1,500-grit silicon carbide papers under water cooling. For distinction of the bottom and top sides of specimens, little notches were made with a dental bur on the edge of the bottom side of the composite discs. Final thicknesses of resin composite disks were measured by a digital caliper (1.2±0.1). Resin composite discs were kept in black bottles until color measurements were done. space by Conclusion: The adhesive systems may influence the final color of the restoration, however the adhesive systems tested in the study caused clinically acceptable discoloration at baseline and after aging.","PeriodicalId":8757,"journal":{"name":"Bezmialem Science","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42641353","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}

Many of the herbal bio-actives have therapeutic effects and distinguished chemical properties that allow them favorable candidates for phytomedicines. The history of traditional herbal medicines, which are the precursors of phytopharmaceuticals, dates back to ancient times. Today, many of the officially approved and widely used medicines are produced by isolating active substances from herbal sources. Although traditional pharmaceutical dosage forms such as tablets, capsules, syrups, solutions, decoctions and ointments are still used today, problems related with the absorption, biotransformation and stability of phytochemicals reduces the efficacy, bioavailability and in some cases safety of herbal medicines. Also, conventional pharmaceutical dosage forms are often providing an immediate release of phytoconstituents. Besides the use of advanced drug delivery systems offer advantages to overcome mentioned problems, they also provide extended release with maximum efficacy associated with minimum side effects. Researches on development of herbal formulations by using novel drug delivery systems have gain attention and the use of nanotechnology-based a huge potential to improve in vivo simulated tests in drug development studies (9). Additionally, nanofibers play an important role in the field of regenerative medicine, which can recover important tissues such as heart, blood vessels, nerves, bones, cartilages, tendons, and joints. This is possible with the combination of 3D printing and electrospinning techniques to form biomimicking nanofiber scaffolds and patches loaded with stem cells (9,10). The unique specifications of nanofibers have made them widely used in treatment of different diseases such as infections, allergy, hypertension, rheumatic diseases, inflammatory autoimmune diseases, diabetes, intracranial aneurism, Alzheimer’s, cardiovascular diseases, gastrointestinal diseases, AIDS, and cancers (11,12). Mechanical properties of nanofibers such as high surface area-to-volume ratio, high porosity, amorphous structure, and flexibility of the nanofiber-based carrier systems to deliver herbal bio-actives through various drug application routes is overviewed.","PeriodicalId":8757,"journal":{"name":"Bezmialem Science","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47644428","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}

The studies on cancer pain management, both in English and Turkish, of which full text versions were accessible, were systematically analyzed, and the studies without full text and ongoing studies were not included. The study was conducted by reviewing Cumulative Index to Nursing and Allied Health Literature, EBSCOhost, MEDLINE, ScienceDirect, Ovid, ProQuest, Web of Science, and ULAKBİM National DataBases. There were no year restrictions in screening. Keywords such as “cancer pain”, “cancer pain management”, “reiki” and “palliative care” were used to access the studies. Nineteen research papers were accessed and 5 of them were found to be compatible with the inclusion criteria of our study. Cohrane was established as the guideline to determine levels of evidence. Of the included studies, one was a randomized controlled study, three were experimental studies, the other one was a systematic review. In our day, randomized controlled studies examining the effect of reiki therapy on pain in cancer patients who receive palliative care are limited. In particular, studies have shown that reiki is even more effective in reducing pain when used in addition to pharmacological treatment and conventional nursing care. It is observed that the studies are carried out with a small sample number and generally with a single group. Pain assessments are usually performed with care” were used to access the studies. Also, the reference list of all randomized clinical trials and review papers were checked to find suitable studies that were not identified by electronic search. After the abstracts of the papers were scanned, 19 papers were reached. It was determined that 5 of these studies met the criteria of inclusion in the research. These studies were analyzed separately When we examine the effect of reiki on physical and psychological recovery in cancer patients treated in palliative care, it is reported that reiki has a positive effect on reducing pain. However, there are gaps in matters such as which hand position to use in reiki therapy, the duration and frequency of the reiki session, and the application period. For this reason, it is recommended to conduct randomized controlled studies with a large sample group.","PeriodicalId":8757,"journal":{"name":"Bezmialem Science","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42334926","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}
