Left\u0000ventricular compliance appears to decline with age, which could explain why the\u0000elderly have such a high rate of heart failure. Changes in heart function with age\u0000are associated with an increased risk of cardiovascular death and morbidity. Various techniques have been used to measure the impact of age on heart structure and\u0000function. Subject and methods: The study included 221 healthy adult male and\u0000female volunteers (160 females and 61 males, 20–80 years of age). All healthy\u0000subjects volunteered to participate in this study. They were classified according to\u0000their age. All healthy subjects enrolled in the study underwent myocardial perfusion imaging following the 2-day rest–stress 99mTc sestamibi (GSPECT) protocol.\u0000At rest and during stress, end-diastolic volume, end-systolic volume, and ejection\u0000fraction using the GSPECT software were assessed both at rest and during stress\u0000for comparison. The following parameters were measured: left ventricular\u0000end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV),\u0000and left ventricular ejection fraction (LVEF). The results show that the change in\u0000left ventricular ejection fraction (LVEF) decreased during rest and stress in all age\u0000groups. In contrast, the change in left ventricular end-systolic volume (LVESV)\u0000increased during stress and rest compared with the left ventricular end-diastolic\u0000volume (LVEDV) for all ages.

Therefore, it can be used to prevent and arrest\u0000dental caries. Riva Star (SDF) treatment alone will stop cavities but will not reverse the cavitation. The Silver Modified Atraumatic Procedure, often known as\u0000Smart, is the optimum technique for regaining the tooth's structure and function.\u0000Glass ionomer was introduced in (1972) as a new material that has become one of\u0000the most widely used materials in restorative dentistry. By releasing fluoride ions,\u0000this material has a therapeutic impact on the surrounding tooth structure. Microleakage is the ingress of bacteria, its byproducts, toxins, chemicals, oral fluids,\u0000and ions between the margins of the restoration and the cavity walls. Dental restoration lifetime is significantly influenced by microleakage at the toothrestoration contact. Material and method: In this study, we used 32 primary molars, class V cavities prepared on the buccal surface of all teeth. The teeth were\u0000divided into 2 groups: Group 1: 16 teeth treated with 38%SDF 8 of them restored directly with GIC filling and the other 8 restored after 14 days; Group 2:\u000016 teeth as control group left untreated with 38% SDF,8 teeth restored directly\u0000and 8 restored after 14 days.

Result: results\u0000of this study showed a significant difference in microleakage between two-time\u0000intervals in which microleakage in GIC filling decreased at 14-day intervals than\u0000that of first-day interval in the experimental group, while in the control group,\u0000microleakage at 14 days intervals was higher than first-day interval, but it was\u0000not significant. Conclusion: Pretreatment of the primary teeth with SDF can decrease the microleakage of GIC restoration. If placed after 14 days, the microleakage would be lesser than that if the restoration was placed directly after SDF\u0000treatment. Therefore, it is recommended that SDF treatment be done, followed by\u0000a permanent restoration after 14 days, so the null hypothesis cannot be accepted.\u0000Keywords: Microleakage, Silver diamine fluoride, Glass ionomer filling, noninvasive dentistry","PeriodicalId":443152,"journal":{"name":"Sumer 1","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132762080","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}

Also, Ganoderma lucidum (G. lucidum) solution was prepared and added to\u0000the neat solution by three ratios (1wt%, 3wt% and 5wt%), which was then\u0000pumped by electrospinning technique to create a nanofiber bead. Solutions results\u0000showed that G. lucidum caused drag reduction, decreasing the viscosities, facilitating solution flow inside the needle and leading to the formation of fine nanofibers easily. Also, at low G. lucidum ratios, the electrostatic repulsion overcomes\u0000the surface tension, which enables fibers to escape from the \"Taylor cone\" tip and\u0000gather on the collector. As well as the electrical conductivity increased due to the\u0000ease of movement of HAc ions due to viscosity reduction. FTIR results proved no\u0000losses of any component of the net blend, and there is no chemical reaction\u0000among them. Results of the obtained nanofiber showed that, with the G. lucidum\u0000addition, there is an increment in fiber diameter, number of beads, the goodness\u0000of orientation and surface roughness. G. lucidum also reduced the wettability, the\u0000crystallinity and the enthalpy consumed during the thermal transition.\u0000Keywords: Ganoderma lucidum, FESEM, Directionality Histogram,\u0000Electrospinning, Wettability","PeriodicalId":443152,"journal":{"name":"Sumer 1","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133227921","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}
