Tocopherol contents of some Turkish wine by-products

The aim of this study was to determine the tocopherol contents of wine by-products including grape seed, pomace (seed, skin and stem) and bagasse (skin and stem) by using two different extraction methods in order to evaluate the possibilities of them as natural non-polar antioxidants. Cold extraction appeared to give more tocopherol contents in seeds than hot extraction. But hot extraction was found more suitable for pomace and bagasse. α-Tocopherol was the most abundant tocopherol in the grape seed, pomace and bagasse. Although γ- and δ-tocopherols were found in the samples with low concentrations, β-tocopherol was not detected in the samples. Kalecik karası had the highest α and total tocopherol compared to the other cultivars. On the other hand, hot extracted bagasse in all cultivars gave the highest tocopherol contents. As a conclusion, wine by-products, a large scale wastes, can be evaluated both to get natural tocopherol source and to obtain economical gain.     

Serum iron as an indicator of acute inflammation in cattle

The aim of this study was to assess the value of serum iron concentration in the diagnosis of acute inflammation in cattle. The diagnostic value of this approach was compared with that of various other hematological tests, including commonly used techniques that measure the levels of various other acute-phase proteins. The study population comprised 10 cows with acute traumatic reticuloperitonitis (RPT group) and 10 cows with acute mastitis (mastitis group) admitted to the Veterinary Teaching Hospital at Firat University (Elazi?, Turkey). Ten cows from local barns, kept and fed under same conditions as the diseased animals, were used as controls. After the clinical examination, blood samples were collected for biochemical, hematological, and acute-phase protein (haptoglobin, serum amyloid A, α-1 acid glycoprotein, and fibrinogen) analyses. The mean levels of serum iron in the RPT, mastitis, and control groups were 6.00, 7.82, and 26.78 µmol/L, respectively. Serum iron level was significantly reduced in the RPT and mastitis groups. The results of this study indicate that serum iron analysis, preferably in combination with other markers of inflammation, may be a useful diagnostic tool for acute inflammation in cattle. Because serum iron measurement is individually available and easily applicable, it may be used for clinical cases as well as the determination of herd health.     

Long-wavelength monolithic VCSEL arrays with high optical output power

Two-dimensional vertical-cavity surface-emitting laser (VCSEL) arrays at 1.55 /spl mu/m wavelength with parallel operation of single- or multimode devices are presented. 3/spl times/3 VCSEL arrays show maximum output powers beyond 30 mW and conversion efficiencies as high as 22%.     

Beyond Lack and Excess: Other Architectures/Other Landscapes

Familiar binary categories of architecture such as Western/regional, high style/vernacular and modern/primitive are crucial in guarding its disciplinary boundaries. In the first part of my article, by analyzing a number of paradigmatic architectural texts, I argue that notions of lack and excess are instrumental in maintaining the largely superimposed binary constructions of West/non-West and architecture/nonarchitecture. Then, through a particular reading of a non-Western site, I explore ways of rethinking the categories of architecture and non-Western beyond such binary oppositions.     

Tenuous boundaries: women,domesticity and nationhood in 1930s Turkey

In the 1930s modern architecture was highly popularised in Turkey mostly through the widespread promotion of the modern house. In the early stages of nation building, the modern house became one of the most potent symbols of the modern nation, which aspired to enter the European economic, cultural and political milieu as an equal partner. The image of the modern Turkish woman played a somewhat similar role, her increasing access to various aspects of the public sphere being highly publicised as the success of Turkish modernisation. Despite obvious links between women and architecture, ranging from their active promotion as suitable images for the new nation to the physical appearance of women in public spaces, issues of gender and sexuality remained conspicuously absent from the architectural historiography of modern Turkey. In this paper, I offer critical readings of contemporaneous representations that relate the modern house and modern Turkish woman to uncover the complicated and contradictory levels that constitute the seemingly coherent narrative of architectural and cultural modernisation. The analysis of the relationship between sexuality, space and architectural discourse effectively complicates the architectural historiography of modern Turkey and shows the active participation of architecture in the production of the social/cultural realm.

Erythrocyte folate status and serum iron levels in patients undergoing hemodialysis

The present study was aimed to evaluate erythrocyte folate and the iron levels in diabetes and hypertension patients treated with/without hemodialysis. The effects of erythropoietin and iron treatment as well as vitamin supplementation on measured parameters were considered. The 67 controls consisted of healthy subjects (n = 22), hypertensive subjects (n = 22), and diabetic subjects (n = 23) without any renal disorder. According to primary renal disorders, the patients undergoing hemodialysis (n = 68) were classified into four groups as diabetic nephropathy, hypertensive nephropathy, reflux nephropathy or interstitial nephritis, and renal insufficiency depending on other causative factors. The mean value of erythrocyte folate levels of all patients undergoing hemodialysis was higher than the healthy control group (P < 0.05). Erythrocyte folate levels in hypertensive and diabetic nephropathy patients were higher than their own hypertensive or diabetic controls and also healthy controls (both, P < 0.05). Serum iron levels of all subgroups in hemodialysis patients were found to be similar with healthy controls (all, P > 0.05). The only significance observed within the subgroups was between diabetic controls and diabetic nephropathy patients (P < 0.05). None of the treatment or supplementation of erythropoietin, iron and vitamin affected erythrocyte folate levels (all, P > 0.05). The increase in erythrocyte folate status of patients with end stage renal diseases might be the result of sum or individual effects of causative factors such as renal pathology, compensation mechanism against renal anemia, or routine folate supplementation.
