OBJECTIVES Tolerance induction to prevent development of nickel allergy has been suggested with permanent dental braces. We wanted to find out which effect orthodontic treatments had had on the development of nickel allergy in university students.

AIM To achieve healing of cutaneous deep and complicated ulcers, along with adequate ulcer debridement and microbespecific antibiotics, any fluid and/or exudate stasis should be avoided. METHODS We have designed a surgical procedure of ulcer piercing and drainage with silastic tube which allows a continuous or daily cleansing of any pierced hidden tract by positive pressure irrigation. This p...

The role of the alternative respiratory pathway in the protection of plants against biotic stress was examined in transgenic tobacco (Nicotiana attenuata) plants (irAOX) silenced in the expression of ALTERNATIVE OXIDASE (AOX) gene. Wild-type and irAOX plants were independently challenged with (1) chewing herbivores (Manduca sexta), (2) piercing-sucking insects (Empoasca spp.), and (3) bacterial...

Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, ...

A finite collection C of closed convex sets in R is said to have a (p, q)-property if among any p members of C some q have a non-empty intersection, and |C| ≥ p. A piercing number of C is defined as the minimal number k such that there exists a k-element set which intersects every member of C. We focus on the simplest non-trivial case in R, i.e., p = 4 and q = 3. It is known that the maximum po...
