Polyethyleneimine brushes effectively inhibit encrustation on polyurethane ureteral stents both in dynamic bioreactor and in vivo.

Merve Gultekinoglu, Barış Kurum, Siyami Karahan, Didem Kart, Meral Sagiroglu, Nusret Ertaş, A Haluk Ozen, Kezban Ulubayram,

Polyurethane (PU) ureteral stents have been widely used as biomedical devices to aid the flow of the urine. Due to the biofilm formation and encrustation complications it has been hindered their long term clinical usage. To overcome these complications, in this study, cationic polyethyleneimine (PEI) brushes grafted on PU stents ... Read more >>

Aromatase expression in the cerebellum of the dog infected with canine distemper virus.

Murat Yarim, Mustafa Yavuz Gulbahar, Tolga Guvenc, Siyami Karahan, Nobuhiro Harada, Yonca Betil Kabak, Mehmet Onder Karayigit,

Aromatase is the enzyme that catalyzes the biosynthesis of estrogens. It is implicated in neuroprotection.The present study investigated aromatase expression in the cerebellum of dogs infected with canine distemper virus (CDV), a disease characterized by demyelination in the white matter of the cerebellum. The presence of CDV infection was confirmed ... Read more >>

Cerebellum progesterone concentration decreased in canine distemper virus infection.

Gul Fatma Yarim, Siyami Karahan, Murat Yarim,

Progesterone has neuroprotective effects including augmentation of myelination in the central and peripheral nervous system. This study was designed to determine if demyelinating lesions in the cerebellum resulting from canine distemper virus (CDV) infection are associated with progesterone levels. Progesterone was measured using radioimmunoassay in samples of the cerebellum, corpus ... Read more >>

Immunolocalization of 3beta-hydroxysteroid dehydrogenase in normal and hyperplastic ram prostates.

Murat Yarim, Siyami Karahan, Nalan Kabakci, Tarik Atmaca,

The enzyme 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is essential in the synthesis of all steroids by cleaving dehydroepiandrosterone to androstenedione. In the present study, 3beta-HSD immunoreactivity was investigated in the prostate of Akkaraman breed rams aged older than 3 years. Five normal and five hyperplastic ram prostates were processed for immunohistochemistry. Prostate ... Read more >>

Effects of water quality and fish size on toxicity of methiocarb, a carbamate pesticide, to rainbow trout.

Ilhan Altinok, Erol Capkin, Siyami Karahan, Muhammet Boran,

The acute toxicity of methiocarb in juvenile rainbow trout (Oncorhynchus mykiss, 3.25±0.79g) was evaluated in glass aquaria under static conditions. Nominal concentrations of methiocarb in the toxicity test ranged from 1.25 to 7.50mgL(-1). The concentrations of methiocarb that killed 50% of the rainbow trout within 24-h (24-h LC(50)), 48-h LC(50), ... Read more >>
