Objective: Acute kidney disease develops 16% - 30% of patients with preoperative impaired renal functions. Our aim of this study was to compare postoperative renal outcomes using two open heart surgery techniques, on-pump beating heart (OPBH) and conventional on-pump (COP), in patients who have preoperative low glomerular filtration rate (eGFR) as an indicator of creatinine clearance. Methods: From 2004 to 2015, 341 patients with preoperative creatinine clearance were lower than 90 ml/min/1.73m2 were selected for this study. On-Pump beating heart was performed in 111 patients (Group I). Conventional on-pump technique was used in 200 patients. In the remaining patients, we measured postoperative Tumor Necrosis Factor Alpha (TNF-alpha), cardiac troponin I (cTn-I), Brain natriuretic peptid (NT-Pro- BNP), creati-nine (Cr), blood urea nitrogen (BUN) and postoperative eGFR daily until day four after surgery. Results: There were no differences in baseline levels of TNF-alpha, NT-Pro-BNP, BUN, cTn-I, Cr levels between the groups. Cardiopulmonary bypass (CPB) time were much longer and cumulative inotrope use was significantly higher in patients underwent COP (P Conclusion: Our study showed that on-pump beating heart CABG technique provides a morbidity benefit and is associated with a lower risk of peroperative LOS in patients with mild renal disfunction. Our study results suggest that OPBH is superior to the COP in terms of postoperative renal injury and cardiac mediators.

Anatolia, also named as Asia Minor, is known as one of the gene centers for a number of the life forms in the world. Caucasian honeybee is one of the important gene resources in Anatolia and mountain type is the most significant variant. This honeybee race is black colored and similar to the Carniola bees regarding shape, size and hair cover. Body is moderate structured, slim and long as abdomen is thin. Chitin is dark. Hair cover is black and short (0.335 ± 0.031 mm). Hair color of worker bees is livid grey as chest hair color of drones is black. All abdominal rings are black colored. It has the longest tongue (7.046 ± 0.189 mm) among the all honeybee races. Caucasian bees form strong colonies but their colonial development is slow. They swarm only very little and are good tempered. They are good pollinators for alfalfa, clover and similar plants with deep tube flowers and can work under unfavourable conditions. It is known that homeland of Caucasian bee (A. mellifera caucasica) is upper valleys of mid-Caucasia (Georgia, Azerbaijan and Northern Caucasus). Its distribution area is extended to Kars, Ardahan and Artvin provinces in North-Eastern Anatolia of Turkey. The area including Posof district of Ardahan province and its all villages and 6 villages of Camili basin in Borcka district of Artvin province is housing different ecotypes of this race. So, this area was isolated for gene conservation of Caucasian bee by Ministry of Agriculture and Rural Affairs in 2008. In-situ conservation studies for Caucasian bee (A. mellifera caucasica Gorbachev) have been continuing under the Indigenous Gene Resources Conservation Scheme with a total of 6,960 colonies under on-farm conditions.
