AIM This study tested the null hypothesis that there is no difference on microleakage of dentin-bordered composite restorations using single or double coats of adhesive from one-bottle adhesive systems. METHODS AND MATERIALS The enamel surface was removed from freshly extracted bovine teeth, and standardized Class V cavities (3 x 3 x 1.5 mm) were made at the cervical areas of buccal surfaces....

It is not surprising that the literature on British business history has paid special attention to J. & P. Coats, the Paisley-based cotton thread manufacturing company. The company created ahighly profitable conglomerate with an efficient management structure after 1896, thereby providing a good example for the other amalgamations of the late nineteenth and early twentieth centuries. J. & P. Co...

BACKGROUND The Venezuelan equine encephalitis (VEE) virus replicon system was used to produce virus-like replicon particles (VRP) packaged with a number of different VEE-derived glycoprotein (GP) coats. The GP coat is believed to be responsible for the cellular tropism noted for VRP and it is possible that different VEE GP coats may have different affinities for cells. We examined VRP packaged ...

Many protozoans and some other organisms possess contractile vacuoles (CVs), membranous organelles which help maintain cellular water/ electrolyte balance by extracting a dilute solution from the cytoplasmic colloid and expelling it from the cell (35, 37). Although the similarity of CV function in the various organisms has long been recognized, the expected similarity of morphological elements ...

Anterior chamber cholesterolosis is a rare phenomenon typically associated with non-neoplastic conditions such as hyphema or Coats disease; it has never been reported to be associated with intraocular malignancy. We report a case of anterior chamber cholesterolosis presenting in the setting of retinoblastoma and discuss clinical features relevant for its differentiation from Coats disease.

The assembly of COPI into a cage-like lattice sculpts membrane vesicles that transport cargo from the Golgi apparatus. Now, Lee and Goldberg (2010) present X-ray crystal structures of COPI suggesting that these coats combine selected features of two other archetypal coats, clathrin and COPII.

BACKGROUND Coats' disease is a non-hereditary ocular disease, with no systemic manifestation, first described by Coats in 1908. It occurs more commonly in children and has a clear male predominance. Most patients present clinically with unilateral decreased vision, strabismus or leukocoria. The most important differential diagnosis is unilateral retinoblastoma, which occurs in the same age grou...

Coats' disease diagnosed in adulthood is rare; therefore, the treatment options and longer clinical course are not well established. We report on two cases of adult onset Coats' disease, which have been observed for more than 10 years after conventional treatment. In the first case, a 76-year-old man with 9 years of diabetic retinopathy noticed a visual field defect in his left eye. Yellowish s...

BACKGROUND Coats' disease is an exudative retinal detachment with vascular telangiectasis occurring mostly in male children, the age group most affected by retinoblastoma. OBJECTIVES Compare the differential diagnoses of Coats' disease Establish recommendation to early disease detection. MATERIALS AND METHODS A 3-year-old female child was referred to Muhimbili National Hospital (MNH), Tanza...
