Objective(s) Staphylococcus aureus is both a successful human commensal and a major pathogen. In this study we investigated the genetic diversity of 26 S. aureus isolates recovered from human skin and urinary tract infections. Materials and Methods Typing procedure for the studied S. aureus isolates was performed based on PCR amplification of the aroA gene, which encodes the enzyme 5-enolpyr...

Ultrasonography is an accurate and accessible method for detecting polycystic kidney disease (PKD), an inherited autosomal dominant disease, and other urinary tract diseases. The present work is a preliminary study of PKD and urinary tract abnormalities using ultrasonography in Persian and other long hair cats in Iran. This study was conducted on 83 cats including 68 Persian cats and 15 Persian...

Recent studies have indicated changes in the glottal excitation source characteristics apart from vocal tract resonances due to tongue tip trilling. In this paper we study the significance of changing vocal tract system and the associated glottal excitation source characteristics due to trilling, from perception point of view. These studies are made by generating speech signal by either retaini...

although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (gi) melanoma has been reported in rare cases. in this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(nf1). both cases showed no evidence of any lesions in skin and eye. malignant melanoma of gi tract...

a rare case of diffuse lymphomatous polyposis of the gastrointestinal tract is reported in which the patient presented with abdominal pain, weight loss and bloody diarrhea. x-rays revealed multiple polyps involving the stomach, small intestine and colon. biopsies confirmed the diagnosis of lymphomatous polyposis. the duration of symptoms and signs was 3 months. diffuse lymphomatous polyposis of...

The aim of this research was to develop a flexible, high quality articulatory speech synthesis tool. One feature of this research tool is the simulated annealing optimization procedure that is used to optimize the vocal tract parameters to match a specified set of formant characteristics. Another aspect of this study is the derivation of a new form of the acoustic equations. A transmission-line...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...
