Stakeholders’ Perspectives on Utilization of Logging Residues for Bioenergy in Turkey

Although using logging residues for bioenergy is not a new issue for countries such as Sweden, Finland, Austria, Germany, etc. that are developed in terms of forestry, it is a new issue that requires studying for countries such as Turkey. This study investigates the views of forest engineers working in forest enterprises, researchers working in forestry research institutes and academicians working at universities concerning the use of logging residues for bioenergy that are not currently used in energy production. Within the framework of the study, a questionnaire was sent out to 181 forest engineers, 77 academic staff members and 29 research institute employees, a total of 287 respondents. According to the results of the study, logging residues that are either left in the forest floor or collected by forest villagers for the purpose of fire wood have a favorable potential for energy and forestry if they are used in bioenergy production. Thus, the issue is substantial and of primary importance for Turkey. On the other hand, there are barriers in developing bioenergy sector and using logging residues for this purpose. In order to remove these barriers, first of all, forestry administration should clarify its strategies and policies related to the issue

Nebivolol And Quinapril Reduce P-Wave Duration And Dispersion In Hypertensive Patients

We aimed to investigate the effects of nebivolol and quinapril treatments on P-wave duration and dispersion in hypertensive patients. Hypertensive patients who were in sinus rhythm were assigned to the two treatment groups and received either 20 mg quinapril/day or 5 mg nebivolol/day. P-Wave dispersion (PWD) was measured at baseline and after four weeks of treatment and defined as the difference between the maximum (Pmax) and the minimum (Pmin) P-wave duration. The study group consisted of 54 patients (Mean age: 53 ± 9 years, 46% women) with 27 patients in each group. At 4-week follow up both treatment groups showed a significant reduction (p< 0.001) in systolic (SBP) and diastolic blood pressure (DBP). Heart rate (HR) reduction was significant in patients receiving nebivolol (P=0.001). Both groups showed a similar (P=0.413 for PWD, p=0.651 for Pmax) but significant reduction in PWD (nebivolol: -16± 14, P< 0.0001 and quinapril: -13± 11, P< 0.0001) and Pmax (nebivolol: -10± 11, P=0.001 and quinapril: -9± 11, P=0.001). A 2 (Time) x 2 (Group) mixed-model repeated-measures analysis of variance revealed that the main effect of Time was significant for Pmax (P=0.002) and PWD (P=0.008) after controlling for changes in SBP, DBP and HR. However, the main effect of Group and Time x Group interaction was not significant for both variables (All p values > 0.05). In conclusion, short-term treatment with nebivolol and quinapril produces a similar but significant reduction in Pmax and PWD in hypertensive patients. This effect is independent of blood pressure and heart rate changes

An incidental detection of aortic aneurysm on Tc-99m MAG3 renal scintigraphy

A 71-year-old man with newly diagnosed hypertension was referred for Technetium-99m mercaptoacetyltriglycine (Tc-99mMAG3) renal scintigraphy to evaluate the recent onset of impairmentin renal functions. Dynamic imaging revealed activity flowwhich was suspicious for aortic aneurysm (AA) with a concurrent decrease in left renal blood flow. CT angiography of the thoracoabdominal aorta confirmed that this area corresponded to AA. The purpose of this report was to present the first case of incidental detection of AA on Tc-99m MAG3 scintigraphy and highlight the importance of correlative imaging for thediagnosis of abnormal radioactivity accumulation in the regionof vascular structures

The Level of hs-CRP in Coronary Artery Ectasia and Its Response to Statin and Angiotensin-Converting Enzyme Inhibitor Treatment

Background/Aim. Coronary artery ectasia (CAE) was thought of as a variant of atherosclerosis. C-reactive protein (CRP) which is among the most sensitive markers of systemic inflammation, and elevation of systemic and local levels of this inflammatory marker which has been associated with an increased risk for cardiovascular disease in the obstructive coronary artery disease (O-CAD) are well known, but little was known in CAE. The anti-inflammatory effects of statins and the effect of angiotensin-converting enzyme (ACE) inhibitors on endothelial dysfunction are well established in atherosclerosis. The aim of the present study was to investigate CRP level and its response to statin and ACE inhibitor treatment in CAE. Materials and method. We measured serum hs-CRP level in 40 CAE (26 males, mean age: 56.32 ± 9 years) and 41 O-CAD (34 males, mean age: 57.19 ± 10 years) patients referred for elective coronary angiography at baseline and after 3-month statin and ACE inhibitor treatment. Results. Plasma hs-CRP levels were significantly higher in CAE group than O-CAD group at baseline (2.68 ± 66 mg/L versus 1, 64 ± 64, resp., P < .0001). Plasma hs-CRP levels significantly decreased from baseline 3 months later in the CE (from 2.68±0.66 mg/L to 1.2±0.53 mg/L, P < .0001) as well as in the O-CAD group (from 1.64±0.64 mg/L to 1.01±0.56 mg/L, P < .001). Conclusion. We think that hs-CRP measurement may be a good prognostic value in CAE patients as in stenotic ones. Further placebo-controlled studies are needed to evaluate the clinical significance of this decrease in hs-CRP

Variations spatio-temporelles de l’allocation des macronutriments chez Smilax excelsa L. (Liliaceae)

Allocation patterns of macronutrients (N, P and K) of a liana species Smilax excelsa were investigated in different habitats and along growing season. Macronutrient concentrations significantly differed according to the season (except for leaf K concentration). Similarly, significant differences were also found among sampling stations except for stem and rhizome N and rhizome K% concentrations. Soil macronutrient concentrations were significantly different among studied stations, but not among seasons. S. excelsa individuals occurring in open canopies and overstory positions allocated more macronutrients to fruits as compared to those occurring in closed canopies and understory positionsL'allocation des nutriments (N, P et K) dans la liane Smilax excelsa a été étudiée dans divers habitats au long de la saison de croissance. Les concentrations de macronutriments (à l'exception de la concentration en K foliaire) différaient de manière significative selon la saison. De même, des différences significatives des concentrations ont également été observées entre les stations échantillonnées, sauf pour N des tiges et rhizomes et K des rhizomes. Les concentrations de macronutriments du sol différaient significativement selon les stations mais pas selon les saisons. Les S. excelsa des canopées ouvertes et celles en position émergente allouaient davantage de macronutriments aux fruits que celles des canopées fermées ou en position de surcimées
