Objective: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. Materials and Methods: A prospective series of 74 consecutive patients (average age: 57.6 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. Results: The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. Conclusion: Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.

Enrichment of poultry manure with biomass ash to produce organomineral fertiliser

Omer Hulusi Dede,Hasan Ozer 대한환경공학회 2018 Environmental Engineering Research Vol.23 No.4

In this study, the contribution of hot biomass ash to enrichment of the mineral content and to reducing the moisture content of broiler poultry manure was investigated. For this purpose, the mixtures have been prepared by adding biomass ash at varying rates (10%, 20%, 30%, 40% and 50%) and at different temperatures (100℃, 150℃, 200℃ and 250℃) according to the dry matter content (74.77%) of the poultry manure. The results showed that incorporation of biomass ash into poultry manure at 50% at 250℃ reduced the moisture content from 25.23% to 9.82%. Regarding the maximum N in the final product, the ideal temperature of biomass ash has been obtained at 150℃. The highest nutrient contents were obtained at 50% biomass ash incorporation. The highest dose of biomass ash application had significantly increased nutrients, such as Ca (19.34%), K (4.03%), Fe (1,545 ㎎/㎏), Mn (812 ㎎/㎏) and Zn (479 ㎎/㎏) in the final organomineral fertiliser formulation. Overall, it was concluded that the addition of hot biomass ash can dramatically decrease the moisture content of poultry manure and therefore provide odour and pathogen removal and increase its plant nutrient content.

Turan Ege,Melih Hulusi US,Mustafa Cikirikcioglu,Cavidan Arar,Enver Duran 연세대학교의과대학 2006 Yonsei medical journal Vol.47 No.3

This study was designed to examine the relationship between pericardial fluid and plasma CRP levels, and to alterations in other biochemical parameters in patients undergoing Coronary Artery Bypass Grafting (CABG). The study group consisted of 96 Coronary Artery Disease (CAD) patients who were referred to our clinic for a CABG procedure and from whom sufficient amount of pericardial fluid could be collected. The patients were classified into 3 groups: Stable Angina Pectoris (SAP) (n=27), Unstable Angina Pectoris (USAP) (n=36), and Post-Myocardial Infarction (PMI) (n=33). Levels of CRP, glucose, albumin, total protein, Creatine Kinase (CK), Creatine Kinase-MB (CK- MB), and Lactate Dehydrogenase (LDH) were determined in pericardial fluid samples and in simultaneously collected blood samples from radial artery. The pericardial CRP and LDH levels in the PMI group were higher than in the SAP (p=0.015 and p=0.000, respectively) and USAP (p=0.011, p=0.047) groups. Serum CRP levels in USAP (p=0.014) and PMI (p= 0.000) groups were higher than those in the SAP group. Pericardial albumin levels in the PMI group were higher than in the USAP group (p=0.038). In all groups, the pericardial fluid/serum protein ratio was > 0.5, the LDL ratio was >0.6, and pericardial fluid LDH concentrations were >300mg/dl. CRP level of pericardial fluid was significantly higher in the PMI group than in other groups. However, pericardial fluid LDH levels were higher than blood LDH levels in this group and were also higher than pericardial fluid LDH levels of other groups.

Transobturator Tape Operation Is More Effective in Premenopausal Women than in Postmenopausal Women with Stress Incontinence

Polat Dursun,Tevfik Berk Bildaci,Hulusi Bulent Zeyneloglu,Esra Kuscu,Ali Ayhan 대한비뇨의학회 2011 Investigative and Clinical Urology Vol.52 No.9

Purpose: Midurethral synthetic slings for female stress urinary incontinence are minimally invasive polypropylene mesh tapes that are inserted under the midurethra with trocars. In the past decade, this new technology has become the most commonly performed procedure for female stress urinary incontinence, replacing the traditional open procedures. However, its effectiveness in pre- and postmenopausal women has not previously been compared. Materials and Methods: We assessed the clinical outcome of the transobturator tape (TOT) procedure in premenopausal (n=45) and postmenopausal (n=49) women by means of self-report and the Urinary Distress Inventory 6 (UDI-6) questionnaire. Results: The mean age of the pre- and postmenopausal women was 44 and 60 years, respectively. Mean parity was 2.4 and 3, respectively. There were no significant differences with respect to mean operation time, duration of hospitalization, or intraoperative and postoperative complications. However, premenopausal women were more satisfied with the operation than were postmenopausal women (p=0.014). Also, UDI-6 scores were significantly better in premenopausal women (p=0.027). Conclusions: The TOT operation appeared to be more effective in premenopausal women with stress urinary incontinence. However, further studies with larger sample sizes are needed to confirm our results.

The effects of limestone powder and fly ash as an addition on fresh, elastic, inelastic and strength properties of self-compacting concrete

Hilmioglu, Hayati,Sengul, Cengiz,Ozkul, M. Hulusi Techno-Press 2022 Advances in concrete construction Vol.14 No.2

In this study, limestone powder (LS) and fly ash (FA) were used as powder materials in self-compacting concrete (SCC) in increasing quantities in addition to cement, so that the two powders commonly used in the production of SCC could be compared in the same study. Considering the reduction of the maximum aggregate size in SCC, 10 mm or 16 mm was selected as the coarse aggregate size. The properties of fresh concrete were determined by slump flow (including T₅₀₀ time), V-funnel and J-ring experiments. The experimental results showed that as the amount of both LS and FA increased, the slump flow also increased. The increase in powder material had a negative effect on V-funnel flow times, causing it to increase; however, the increase in FA concretes was smaller compared to LS ones. The increase in the powder content reduced the amount of blockage in the J-ring test for both aggregate sizes. As the hardened concrete properties, the compressive and splitting strengths as well as the modulus of elasticity were determined. Longitudinal and transverse deformations were measured by attaching a special frame to the cylindrical specimens and the values of Poisson's ratio, initiation and critical stresses were obtained. Despite having a similar W/C ratio, all SCC exhibited higher compressive strength than NVC. Compressive strength increased with increasing powder content for both LS and FA; however, the increase of the FA was higher than the LS due to the pozzolanic effect. SCC with a coarse aggregate size of 16 mm showed higher strength than 10 mm for both powders. Similarly, the modulus of elasticity increased with the amount of powder material. Inelastic properties, which are rarely found in the literature for SCC, were determined by measuring the initial and critical stresses. Crack formation in SCC begins under lower stresses (corresponding to lower initial stresses) than in normal concretes, while critical stresses indicate a more brittle behavior by taking higher values.
