BACKGROUND Uniforms are potential reservoirs for hospital organisms, potentially reinfecting the hands of health care workers (HCWs). The study aimed to determine the association between the bacterial contamination of HCWs' hands and uniforms (white coats and scrubs). METHODS HCWs working in 5 intensive care units had cultures obtained from their hands and uniforms (white coats or scrubs). Pa...

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 ...

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.
