one of the complications during a routine dental implant placement is accidental ingestion of the implant instruments, which can happen when proper precautions are not taken. appropriate radiographs should be taken to locate the correct position of foreign body; usually the foreign body passes asymptomatically from gastrointestinal tract but sometimes it may lead to intestinal obstruction, perf...

Magnetic materials such as magnetorheological (MR) fluids, and elastomers exhibit a broad change in their material properties, for example, viscosity storage modulus the presence of magnetic field. Studies related to MR fluid elastomer are extensively available. The brush, meanwhile, is less frequently explored understood. An brush defined by brush-like structures formed from chains particles e...

We studied mixed poly(ethylene oxide) (PEO) and poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) brushes. The question we attempted to answer was: when the chain grafting points are laterally mobile, how will this lateral mobility influence the structure and phase behavior of the mixed brush? Three different model mixed PEO/PDMAEMA brush systems were prepared: (1) a laterally mobile mixed br...

An experiment was conducted to determine the influence the time of brush-cutting can have on plant regrowth and attractiveness to herbivores that browse in linear corridors. The influence of cutting time on leaf flush and senescence, shoot morphometry, and biomass was measured for 3 consecutive years after initial brush-cutting. Results indicate that morphological and phenological attributes of...

A technique for the isolation of intact brush borders from rabbit renal cortex was evaluated. The procedure was monitored by phase and electron microscopy and marker enzymes, i.e. ATP:NMN adenylyl transferase, nuclear; cytochrome oxidase, mitochondrial; beta-glucuronidase, lysosomal; and glucose-6-Pase, microsomal; and indicated an essentially pure preparation of brush borders. The disaccharida...

Zymogram studies of peptide hydrolases from the human intestinal brush border and cytoplasmic fractions produced multiple bands--that is, up to seven--while the brush border membrane produced only a single band of enzyme activity. With all of the substrates tested except L-leucyl-L-leucyl-L-leucine, a band having anodic mobility identical with that produced by the brush border enzymes was produ...

We have isolated a candidate gene (designated Brush-1) located at 13q12-q13, proximal to the retinoblastoma gene (RB1). Brush-1 codes for a 4.7-kilobase mRNA expressed at high levels in normal breast epithelium but drastically reduced in 6 of 13 breast cancer cell lines. RB1 mRNA expression is at normal levels for 5 of these 6 lines suggesting a greater importance of Brush-1 for breast cancer. ...

background: ingestion of caustic substances is the main reason for referral to philippines national poison management and control center among other causes of acute poisoning. rapid assessment of severity of injury is important for treatment and prognosis of these cases. this study was aimed to investigate the correlation of clinical factors with severity of gastrointestinal (gi) mucosal injury...

background: the purpose of this study was to describe the knowledge and attitude of pregnant women in qazvin province, central iran, relating to oral hygiene. methods: the study group comprised of 760 pregnant women living in qazvin, center of iran in 2004. the questions were formulated to evaluate information without the need for dental examination. the age groups between 17-41 years old were ...
