A.L. baraka. A factorial experiment was carried\u0000out using a completely randomized design (C.R.D.) with three replications, which\u0000included two types of irrigation water treated heavy water and soft water, three\u0000levels of field capacity, i.e., %, 50% and 100% and four levels of potassium, i.e.,\u00000, 1000, 2000 and 3000 mg. L-1 The experiment included 72 experimental units.\u0000The results were statistically analyzed, and the means of treatments were compared using the least significant difference under the probability level 0.05. The\u0000following characteristics were measurements: plant height, number of leaf areas,\u0000dry weight of shoot and root systems. Results could be summarized as follows:\u0000Water quality had a statistical effect on the traits under study, as the treatment\u0000with treated heavy water gave the highest values of plant height, number of tillers, number of leaves, leaf area, root and shoots dry weights, which amounted to\u000070.21cm, 14.03leaf, 23.42cm2\u0000, 6.24g, 1.76g respectively compared to soft water,\u0000which amounted to 69.17 cm, 3.52tiller, 13.24leaf, 22cm2\u0000, 58, 5.94 and 1.68g.\u0000The addition of 100% of the field capacity value gave the highest averages of the\u0000following height, number of leaves, leaf area, root and shoots dry weights, which\u0000amounted to 80.80cm, 15.98leaves, 27.81cm2\u0000, 7.69g and 2.15g sequentially. The\u0000addition of 3000 mg.L-1\u0000of potassium gave the highest averages for the traits\u0000plant height, number of leaves, leaf area, shoot dry weight and root dry weight,\u0000where their averages were 73.11cm, 14.66 leaves, 25.11cm2\u0000, 6.63g and 1.87g respectively. Some bi- and tr-interactions between studied factors showed a different effect on the studied characteristics.\u0000Keywords: Wheat plant, water quality, field capacity, potassium concentration.","PeriodicalId":443152,"journal":{"name":"Sumer 1","volume":"4 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":"133828480","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}

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. Results show a significant change in EDV, ESV,\u0000and EF% (16.49%, 30.35%, -7.49%) with p-value < 0.05 for the groups (20- 49).\u0000Also a significant change in EDV, ESV, and EF% (12.13%, 24.86%,-1.62%),\u0000respectively, with p-value <0.05. for age range (50-80) years. In conclusion, in\u0000people with no cardiac functional or structural problems, the aging process is\u0000linked to considerable alterations in left and right ventricular EF, ESV, and EDV.\u0000When assessing SPECT with 99mTc investigations, our findings highlight the need\u0000to adopt age-adapted data as a reference standard.\u0000Keywords: SPECT with 99mTC, Age, Hemodynamics, Rest and Stress","PeriodicalId":443152,"journal":{"name":"Sumer 1","volume":"31 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":"115139647","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}
