background and objective: formalin-fixed paraffin-embedded tissues are a valuable source of dna for molecular studies. we designed and optimized an efficient procedure for dna extraction from formalin-fixed paraffin embedded tissues. materials and methods: seventy three blocks of cervical paraffin-embedded tissues were investigated. dna was extracted using 45 minutes boiling in alkaline solutio...

Thermal stresses in three brands of inlay waxes were numerically analyzed under different cooling conditions using the rheological and thermal properties of waxes. On the basis of this analysis , the shrinkage of the wax pattern was calculated. The larger the stress relaxation of the wax and the higher the ambient temperature, the smaller the thermal stress induced in the wax. The shrinkage of ...

Here we present a simple and low-cost production method to generate paper-based microfluidic devices with wax for portable bioassay. The wax patterning method we introduced here included three different ways: (i) painting with a wax pen, (ii) printing with an inkjet printer followed by painting with a wax pen, (iii) printing by a wax printer directly. The whole process was easy to operate and c...

Plants have been used as a source of wax for cenituries, and the search for plant species that produce more wax of a better quality has been in progress for as many years. It has been recognized only for the past few decades. however, that various factors other than plant species, such as environment, genetic make-up of the plant, and maturity of the plant, may affect the quality and quantity o...

OBJECTIVES One of the most frequent complications in cardiac surgery is postoperative bleeding from the sternum. To diminish the risk of bleeding, bone wax is frequently used for haemostasis. However, we have previously shown that bone wax impairs bone healing and induces inflammation in the sternum. A new, water-soluble polymer wax enriched with gentamicin has haemostatic properties similar to...

BACKGROUND Wax esters are industrially relevant molecules exploited in several applications of oleochemistry and food industry. At the moment, the production processes mostly rely on chemical synthesis from rather expensive starting materials, and therefore solutions are sought from biotechnology. Bacterial wax esters are attractive alternatives, and especially the wax ester metabolism of Acine...

The interception of precipitation by plant canopies can alter the amount and spatial distribution water inputs to ecosystems. We asked whether canopy could locally augment shrubs their crowns funneling (freshwater) as stemflow bases, in a wetland where relict overstory trees are dying persisting only grow on small hummocks that sit above mesohaline floodwaters. Precipitation, throughfall, were ...

The impeding effect of plant surfaces covered with three-dimensional wax on attachment and locomotion of insects has been shown previously in numerous experimental studies. The aim of this study was to examine the effect of different parameters of crystalline wax coverage on insect attachment. We performed traction experiments with the beetle Coccinella septempunctata and pull-off force measure...

We present a physically-inspired model of wax crayons, which synthesizes drawings from collections of userspecified strokes. Paper is represented by a height-field texture, and a crayon is modelled with a 2D mask that evolves as it interacts with the paper. The amount of wax deposition is computed based on the crayon contact profile, contact force, and friction. Previously deposited wax is smea...
