Tubulovesicular structures (particles--TVS) are the only ultrastructural marker for all transmissible spongiform encephalopathies (TSEs) or prion disease as seen by thin section electron microscopy. The latter is stressed as opposed to negative-staining techniques. TVS are spheres or short rods of approximately 27-35 nm in diameter. What is particularly interesting, this size of TVS is also the...

With the market for mobile AMOLED displays still increasing, both Samsung Mobile Display and LG Display have announced that OLED TVs will be commercially available in 2012. OLED TVs have different requirements compared to mobile devices and especially the lifetime has to be significantly longer in TVs. Therefore, Novaled has developed new ETL materials that lead to much longer lifetime in monoc...

BACKGROUND This prospective study evaluates the predictive value of preoperative staging by transvaginal sonography (TVS) in ovarian cancer. PATIENTS AND METHODS In 39 patients presenting with clinical signs and symptoms of ovarian cancer, preoperative systematic staging regarding tumor size (T), presence of ascites (A), peritoneal carcinomatosis (PC), bladder invasion (BI), intestinal invasi...

Aim of this study was to evaluate the performance of saline hydrosonography (HSGM) (also known as saline infusion sonography (SIS)) against transvaginal ultrasound scan (TVS) and hysteroscopy in the diagnosis of uterine cavity lesions. Diagnostic hysteroscopy with biopsy is considered as the "gold standard" to diagnose intrauterine abnormalities. The introduction of HSGM has improved the diagno...

OBJECTIVES To assess the reliability of trans-vaginal-scan (TVS) in measuring the uterine depth (UD) in comparison with ultrasound-guided trial-transfer (UTT). METHODS This prospective study was conducted in 66 consecutive patients undergoing in-vitro fertilization and embryo transfer (IVF-ET). The study took place in a private IVF center in Jeddah, Saudi Arabia between November 2013 and Janu...

Adenomyosis is an idiopathic and benign disease in which ectopic endometrial glands embedded deeply in myometrial smooth muscle with the compensatory hypertrophy of the myometrium surrounding the ectopic endometrium (1, 2). There is a correlation between depth of the infiltration and initial too high stage of adenomyosis. Lesions may characterize as a diffuse or focal lesions. The highest preva...

Background Abnormal uterine bleeding (AUB) is one of the most common clinical problems in gynecology. Transvaginal sonography (TVS) and hysteroscopy are two diagnostic methods for patients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done in clinic with minimal discomfort and much lower expense than operative room. MaterialsAndMethods In our clinical trial study, ...

Background: To compare the value of physical examination, transvaginal sonography (TVS), rectal endoscopic sonography (RES), and magnetic resonance imaging (MRI) for the assessment of different locations of deep infiltrating endometriosis (DIE). Materials and Methods: Ninety-two consecutive patients with clinical evidence of pelvic endometriosis. Physical examination, TVS, RES, and MRI, perform...

INTRODUCTION To reduce the ischaemia time of injured limbs in wartime, temporary vascular shunts (TVS) are commonly used. However, TVS are stabilized at the ends of the injured vessels using manual suture ties, the risk of dislodgement is high, and tightening manual suture ties is too time consuming. TECHNICAL SUMMARY Locked temporary vascular shunts (LTVS) were designed, and each was compose...

PURPOSE Intrauterine lesions (IULs) are a common finding in women of reproductive age, particularly infertile women. Transvaginal sonography (TVS) is a popular tool for IUL detection, but there are conflicting data with respect to its accuracy. METHODS Five hundred and six women were enrolled into the study. Of these, 496 underwent hysterosalpingography and subsequent TVS six different times ...
