Ultrastructural examination of left internal mammary artery under electron microscopy in patients with chronic kidney disease who underwent coronary bypass surgery

Aim: To investigate the vascular damage of internal mammary artery graft with electron microscope secondary to chronic renal failure transmission in patients who underwent coronary artery bypass grafting surgery. Method: A total of 30 patients (10 patients with chronic renal failure and 20 patients without chronic renal failure) who underwent coronary artery bypass graft surgery were included in this prospective study. Left internal mammary artery graft was harvested as conventional fashion with no touch technique. Samples were prepared and then examined with the transmission electron microscope. Every arterial sample was individually examined ultrastructurally, and the changes were recorded. Then the samples of the control group and chronic renal failure group were compared. Results: There were no significant differences between chronic renal failure group and the control group in terms of demographics, comorbidities, intraoperative data and postoperative outcomes, and the groups were statistically similar (p<0.05). Moreover, no statistically significance was detected in terms of structure and ultrastructure between the groups. Conclusion: The results of our study revealed that no ultrastructural changes were observed in the structure of IMA, suggesting that this graft would provide a good graft patency

Our outcomes of aortic valve sparing reimplantation (David procedure) in patients with ascending aortic aneurysm and type A aortic dissection

Aim: To present our outcomes with David procedure in patients with ascending aortic aneurysms (AAA) and type A aortic dissection (AD). Methods: Thirty-six patients, aged between 38-75 years, followed-up in the cardiovascular surgery clinic of our hospital were included in the study. Patients’ demographic data such as age and gender, type of dissection, urea and creatinine values, length of stay in the ICU, duration of hospitalization were recorded. Outcomes of postoperative and long-term ecography were analyzed. Results:  Of the 36 patients included in the study, 26 (72.22%) were male and 10 (22.78%) were female. The mean age of all patients was 60 ± 10 years. Ascending aortic aneurysm (AAA) was found in 20 (55.56%) patients and type A aortic dissection (AD) in 16 (44.44%) patients. In the postoperative echocardiography, 7 (23.33%) patients were normal, while 2 (6.67%) had trace aortic insufficiency, 17 (56.67%) patients had mild aortic insufficiency, 3 (10.00%) patients had moderate aortic insufficiency and 1 (3.33%) severe aortic insufficiency. Echocardiography performed one month after the operation revealed normal pathology in 10 (33.33%) trace aortic sufficiency in 2 (6.67%) patients, mild aortic insufficiency in 17 (56.67%) patients, and moderate aortic insufficiency in 1 (3.33%) patient. Conclusion:  The results of this study indicate that aortic valve-sparing reimplantation (David) procedure can be safely and effectively performed in patients with ascending aortic aneurysm and type A aortic dissection. It eliminates the need for a mechanical prosthesis and its complications

Effects of Coronary Artery Bypass Grafting Surgery on Olfactory and Taste Functions

Conclusion: Our study demonstrated that olfactory function was impaired in patients, who underwent on-pump CABG in the postoperative period, and significant impairment in taste function was present in neither off-pump nor on-pump CABG patients. However, the results of our study should be supported by more comprehensive, prospective, randomized controlled trials with more extensive patient series and by further tests

Diallel analysis of wheat parents and their F-2 progenies under medium and low level of available N in soil

WOS: 000247677500028Due to high production cost and prevention of environmental pollution, it is important to reduce the amount of nitrogen (N) fertilizer used on wheat (Triticum aestivum L.). The aim of this study was to evaluate N use of 6 x 6 diallel wheat F-2 progenies and parental lines at low (NO, no N fertilizer) and high (N+, 160 kg N ha(-1)) N levels. Significant differences were found between N+ and NO application in grain N content, grain N yield, N use efficiency for grain N yield (NUEgn), and N use efficiency for grain yield (NUEgy). The cultivar '84CTO4' showed positive and high general combining ability (GCA) effects for all traits at low N level. Also, it was the best combiner for all traits at both N levels. The cultivar 'Genc 99' was the best parent for GCA effects for grain yield and NUEgy. Hybrids 'Genc 99 x 84CZT04' and '84CZT04 x Weaver' showed positive specific combining ability (SCA) effects for all investigated traits at low and high N levels. Variety '84CZT04 x Apogee' had the best SCA effects for all traits at low N level. Overall, the data suggest that it is probable to select promising lines suitable for low N conditions by the crossing of high N use efficient parents

Clinical and functional outcomes of chondroblastoma located in the pelvic and extremities

Chondroblastoma is a rare benign bone tumor that occurs at a young age and typically affects the epiphyses or apophyses of the long bones. Its treatment is curettage and adjuvant therapy. The aim of this study is to present the results of chondroblastomas that we treat as an oncology center. The information of 26 chondroblastoma patients treated in our clinic between 2009 and 2018 were retrospectively reviewed from the archive. Surgical and functional results, complications and local recurrences were analyzed. Twenty-six chondroblastoma patients, 12 females (46%) and 14 males (53%), with a mean age of 16, were followed up for 75 (37-129) months. Twenty patients (76.9%) presented with complaints of pain, while 4 patients (15.4%) presented with swelling and 2 patients (7%) with pathological fractures. The most common site was the tibia proximal in 6 patients (23.1%). Intralesional curettage + high speed burr was applied to all patients as surgical treatment. Grafts were used to fill the defect in 20 patients. Recurrence was observed in a single patient located in the proximal humerus. The mean Musculoskeletal Tumor Society (MSTS) score was 27.7±1.9. Comprehensive curettage using high-speed burr and bone graft in the treatment of chondroblastoma has good local control, low recurrence rate and excellent functional long-term result.

Assessment of watermelon accessions for salt tolerance using stress tolerance indices

ABSTRACT Salt stress is the most significant constraint for agricultural production in arid and semi-arid regions. Thus, genetically improved stress-tolerant varieties are needed for the future. The identification of salt-tolerant genotypes is the starting point for such breeding studies. This study was conducted to determine and assess the tolerance of different watermelon genotypes under saline conditions. Twenty-two watermelon genotypes and accessions were grown in pots with 3 kg of soil in four saline stress conditions (0 mmol kg-1 as the control, 25, 50 and 100 mmol kg-1 NaCl). The detrimental effects of salt stress on the plants were evident with increasing doses of NaCl. Stress indices calculated over the plant dry weights under the 100 mmol kg-1 salinity level were used to assess the salt tolerance of the genotypes. Stress intensity was calculated as 0.76. Such a value indicated that the highest dose of salt exerted severe stress on the plants. The G04, G14 and G21 genotypes were considered to be salt tolerant, since these genotypes showed the highest values of K/Na and Ca/Na ratios in the plant tissue. The losses in dry mass at severe salt stress reached 75.48%. In principal component analyses, the genotypes had positive correlations with stress tolerance indices of MP (mean productivity), GMP (geometric mean productivity) and STI (stress tolerance index). The GMP and STI indices indicated that G04 (a member of Citrullus colocynthis), G14 and G21 could be prominent sources to develop salt tolerance
