Bone Pain Assessment and Relationship with Parathyroid Hormone and Health-Related Quality of Life in Hemodialysis

Elsurer, Rengin | Afsar, Baris | Mercanoglu, Esra

Renal osteodystrophy is a common problem in renal failure patients. Bone pain is a common manifestation of renal osteodystrophy. The aim of the study was to assess the intensity of chronic bone pain via visual analog scale (VAS) and its relationship with parathyroid hormone, health-related quality of life (HRQoL), and depression in hemodialysis patients. Ninety-five patients recruited were asked to rate chronic bone pain via VAS. Depressive symptoms and HRQoL were assessed by Beck Depression Inventory (BDI) and Short-Form 36, respectively. VAS was positively correlated with intact parathyroid ...Daha fazlası

Protection by L-carnitine against radiation-induced ileal mucosal injury in the rat: Pattern of oxidative stress, apoptosis and cytokines

Akpolat M. | Gulle K. | Topcu-Tarladacalisir Y. | Safi Oz Z. | Bakkal, Bekir Hakan | Arasli M. | Ozel Turkcu U.

Purpose: In this study, we tested the effects of L-carnitine (LC) on radiation-induced ileal mucosal damage. Materials and methods: Thirty Wistar albino rats were divided into five groups. The control group received physiological saline intraperitoneally (i.p.). Radiation-1 and radiation-2 groups received whole-body X-irradiation of 8.3 Gy as a single dose. These groups were sacrificed at the 6th hour and 4th day after irradiation, respectively. The Radiation-1 + LC and the radiation-2 + LC groups received the same dose irradiation plus a daily dose of 200 mg/kg LC. LC was applied one day befo ...Daha fazlası

Effect of ozone oxidative preconditioning in preventing early radiation-induced lung injury in rats

Bakkal, Bekir Hakan | Gultekin F.A. | Guven B. | Turkcu U.O. | Bektas S. | Can M.

Ionizing radiation causes its biological effects mainly through oxidative damage induced by reactive oxygen species. Previous studies showed that ozone oxidative preconditioning attenuated pathophysiological events mediated by reactive oxygen species. As inhalation of ozone induces lung injury, the aim of this study was to examine whether ozone oxidative preconditioning potentiates or attenuates the effects of irradiation on the lung. Rats were subjected to total body irradiation, with or without treatment with ozone oxidative preconditioning (0.72 mg/kg). Serum proinflammatory cytokine levels ...Daha fazlası

Avrupa Birliği ve Türkiye ekseninde yasadışı göç ve iltica paradoksu: Domino etkisi sonrası yaşananlar

Sever, Hanifi | Sever, Muhammed

Göçün günümüzde dünyanın en büyük sorunlarından biri haline gelmesine neden olan pek çok etken bulunmaktadır. Bunlardan en önemlileri; ekonomik eşitsizlik, devletlerin vatandaşlarının can güvenliğini sağlayamaması, siyasi çalkantılar ve şiddet eylemleri olarak sayılabilir. Kaynak veya hedef ülke olsun ya da olmasın, tüm devletleri zor durumda bırakan yasadışı göç sorunlarına hem ulusal, hem de uluslararası alanda çözüm arayışları sürmektedir. Avrupa Birliği, özellikle 2000’den sonra göç ve iltica konuları ile yakından ilgilenmektedir. Önceleri bir gereklilik olarak görülen göçmenlerin, artık b ...Daha fazlası

The influence of dietary alpha-solanine on the waxmoth galleria mellonellal

Büyükgüzel, Ender | Büyükgüzel, Kemal | Erdem, Meltem | Adamski, Zbigniew | Adamski, Zbigniew | Marciniak, Pawel | Ziemnicki, Kazimierz

Plant allelochemicals are nonnutritional chemicals that interfere with the biology of herbivores. We posed the hypothesis that ingestion of a glycoalkaloid allelochemical, ?-solanine, impairs biological parameters of greater wax moths Galleria mellonella. To test this idea, we reared wax moths on artificial diets with 0.015, 0.15, or 1.5 mg/100 g diet of ?-solanine. Addition of ?-solanine to the diet affected survival of seventh-instar larvae, pupae, and adults; and female fecundity and fertility. The diet containing the highest ?-solanine concentration led to decreased survivorship, fecundity ...Daha fazlası

One-step synthesis of block-graft copolymers via simultaneous reversible-addition fragmentation chain transfer and ring-opening polymerization using a novel macroinitiator

Öztürk, Temel | Atalar, Mehmet Nuri | Göktaş, Melahat | Hazer, Baki

One-step synthesis of block-graft copolymers by reversible addition-fragmentation chain transfer (RAFT) and ring-opening polymerization (ROP) by using a novel initiator was reported. Block-graft copolymers were synthesized in one-step by simultaneous RAFT polymerization of n-butylmethacrylate (nBMA) and ROP of ?-caprolacton (CL) in the presence of a novel macroinitiator (RAFT-ROP agent). For this purpose, first epichlorohydrin (EPCH) was polymerized by using H2SO4 via cationic ring-opening mechanism. And then a novel RAFT-ROP agent was synthesized by the reaction of potassium ethyl xanthogenat ...Daha fazlası

Osteogenic activities of polymeric soybean oil-g-polystyrene membranes

Tığlı-Aydın, Rahime Seda | Hazer, Baki | Acar, Merve | Gümüşderelioğlu, Menemşe

A novel biocompatible copolymer membrane was synthesized and characterized for use in guided bone regeneration using polymeric soybean oil-g-polystyrene (PSO-g-PS) graft copolymer which was successfully obtained by free radical polymerization of styrene initiated by PSO peroxide as a macroinitiator at 80 C. Osteoblastic cellular activities of MC3T3-E1 cells on PSO-g-PS membranes with different soybean oil composition (PSO-g-PS1, PSO-g-PS2, and PSO-g-PS3) were evaluated. Nuclear magnetic resonance (1H NMR) spectra showed that PSO inclusion (mol%) was found to be 27, 69, and 51 % for PSO-g-PS1, ...Daha fazlası

Effect of boric acid on antioxidant enzyme activity, lipid peroxidation, and ultrastructure of midgut and fat body of Galleria mellonella

Büyükgüzel, Ender | Büyükgüzel, Kemal | Snela, Milena | Erdem, Meltem | Radtke, Katarzyna | Ziemnicki, Kazimierz | Adamski, Zbigniew

Boric acid is widely used as an insecticide, acaricide, herbicide, and fungicide and also during various industrial processings. Hence, numerous populations are subjects to this toxic compound. Its action on animals is still not fully known and understood. We examined the effect of boric acid on larvae of greater wax moth (Galleria mellonella). The chemical appeared to be toxic for larvae, usually in a concentration-dependent manner. Exposed groups revealed increased lipid peroxidation and altered activity of catalase, superoxide dismutase, glutathione S-transferase, and glutathione peroxidase ...Daha fazlası

Synthesis of antibacterial amphiphilic elastomer based on polystyrene-block-polyisoprene-block-polystyrene via thiol-ene addition

Keleş, Elif | Hazer, Baki | Cömert, Füsun B.

A new type of amphiphilic antibacterial elastomer has been described. Thermoplastic elastomer, polystyrene-block-polyisoprene-block-polystyrene (PS-b-PI-b-PS) triblock copolymer was functionalized in toluene solution by free radical mercaptan addition in order to obtain an amphiphilic antibacterial elastomer. Thiol terminated PEG was grafted through the double bonds of PS-b-PI-b-PS via free radical thiol-ene coupling reaction. The antibacterial properties of the amphiphilic graft copolymers were observed. The original and the modified polymers were used to create microfibers in an electro-spin ...Daha fazlası

Novel water soluble Soya oil polymer from oxidized Soya oil polymer and diethanol amine

Acar, Merve | Çoban, Selim | Hazer, Baki

A cold water soluble, biobased polymer derived from autoxidized soya oil has been described. Oxidized soya oil polymer was obtained by exposure to air under daylight at room temperature. The thickness of the soya oil at the beginning of the reaction and the oxidation time adversely influenced the molecular weight of the soya oil polymer obtained. The oxidized soya oil polymer obtained was then reacted with diethanol amine to obtain a hydroxylated soya oil polymer. The cold water soluble hydroxylated soya oil polymer was characterized by viscosity measurements, elemental analysis, FT-IR, 1H-NMR ...Daha fazlası
