The objective of this article is to offer a simplified and reasonable approach for periodontal disease screening that should be a mandatory part of each and every oral examination. The main purpose of this examination is to answer the question of whether or not there are any infection sites that require periodontal management. This assessment has three parts: the initial patient interview (medi...

One of the fundamental techniques of molecular biology is the isolation of a rare clone from a complex mixture of DNA sequences contained within a library. The isolation of cDNA and genomic clones from highly complex libraries is often an early step in studies aimed at understanding basic biological processes as well as in applied biological research. In a typical genomic library with an averag...

An experimental method is presented for the rapid evaluation of structured solids with microelastic degrees of freedom associated with the microstructure. By contrast with earlier methods based on size effect studies, the present method makes use of a single specimen subjected to holographic interferometry. Results are presented for polymethyl methacrylate and for a dense polyurethane foam, whi...

For a number of years we have considered the Wassermann reaction to be eminently suitable for complete automation. It was after our experience with the Technicon Autoanalyser doing chemical analyses that we decided to experiment with the Wassermann reaction. The following paper records the details of our method, based on the Whitechapel technique (Wilkinson, 1962). It does not include details o...

An efficient and rapid affinity-based screening method for directly fishing out natural alpha-glucosidase inhibitors from Cyperus. rotundus extract by using immobilized enzyme technology combined with UHPLC-QTOF MS analysis was established. As a results, without time-consuming and laborious isolation workload and false positive interference, five natural alpha-glucosidase inhibitors were succes...

A semi-automatic SAR sea ice classification algorithm is described. It is based on combining the information in the original SAR data with those in the three ‘image’ products derived from it, namely Power-to-Mean Ratio (PMR), the Gamma distribution and the second order texture parameter entropy, respectively. The latter products contain information which is often useful during the manual interp...

The California Environmental Protection Agency (Cal/EPA) Environmental Justice Action Plan calls for guidelines for evaluating "cumulative impacts." As a first step toward such guidelines, a screening methodology for assessing cumulative impacts in communities was developed. The method, presented here, is based on the working definition of cumulative impacts adopted by Cal/EPA: "Cumulative impa...

clinical and epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. these beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. therefore screening for antioxidant properties of plant extracts has been one of the interests...

Abuse of laxatives, most of them belonging to the group of colonic stimulants or cathartics, can cause various disorders. Extensive diagnostic work can be avoided by early toxicological screening of the suspected patients with respect to laxatives. Because no screening method of this kind was available, we developed a procedure with which all phenolic and anthraquinone laxatives--except sodium ...
