PURPOSE To evaluate the diagnostic efficiency of the diffusion parameters measured by conventional diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) for discrimination of malignant breast lesions from benign lesions and the normal breast. MATERIALS AND METHODS The study included 52 women with 55 breast lesions (30 malignant, 25 benign).(More)
Selenium (Se), an essential element, plays important roles in human health as well as environmental sustainability. Se hyperaccumulating plants are thought as an alternative selenium resource, recently. Astragalus species are known as hyperaccumulator of Se by converting it to nonaminoacid compounds. However, Se-metabolism-related hyperaccumulation is not(More)
OBJECTIVES/HYPOTHESIS To electrophysiologically and histomorphologically demonstrate the effects of intratympanic corticosteroids administered following an acoustic trauma on cochlear hair cells. METHODS The trial was performed on 16 Wistar albino rats. The rats underwent distortion product otoacoustic emissions (DPOAE) measurement before the acoustic(More)
Although pre- and postoperative imaging of Achilles tendon rupture (ATR) has been well documented, radiographic evaluations of postoperative intratendinous healing and microstructure are still lacking. Diffusion tensor imaging (DTI) is an innovative technique that offers a noninvasive method for describing the microstructure characteristics and organization(More)
In this study it was aimed to investigate inducibility of secondary metabolism in Astragalus chrysochlorus by yeast extract which is known to cause the synthesis of defensive phenolic metabolites. Cell suspension cultures of Astragalus chrysochlorus responded to elicitor treatment (10 gl(-1) yeast extract) by increasing phenylalanine ammonia lyase (PAL E.C.(More)
Squamous cell carcinoma may present with atypical peripheric nerve symptoms. Lung cancers are the second most common cancer which metastasize to the brachial plexus. Metastatic brachial plexopathy (BP) is almost always unilateral. We document MR images of a case with squamous cell lung cancer presenting as bilateral metastatic BP. Although very rare,(More)
