For the wide range of antitrust cases involving allegations of monopoly or monopolization (or variations on that theme), the presence of market power is a necessary prerequisite for finding liability. In turn, the definition or delineation of a relevant market is essential for measuring a defendant's market share -a key determinant of the presence or absence of market power. Unfortunately, ther...

To regenerate auxotrophic mutants of Physcomitrella patens, two media of increasing complexity were developed. The survival rate of protoplasts was around 30% higher on full medium when compared to standard minimal medium. Protoplast survival was higher in a medium containing 2.5 mmol/L ammonium tartrate compared to a medium with 5 mmol/L of this compound. Solid medium had a positive effect on ...

Demodicosis is an infestation of the skin with Demodex, an ectoparasite commonly found on the face. A cross-sectional study was conducted to detect the presence of the ectoparasite and the outcome of facial cleanser and moisturizer usage on its infestation. Universal sampling was performed among 390 medical students, age 20-25 years old in the Klang Valley of Malaysia. The biodata of the partic...

Freter, Rolf (Jefferson Medical College, Philadelphia, Pa.), and Atsushi Ozawa. Explanation for limitation of populations of Escherichia coli in broth cultures. J. Bacteriol. 86:904-910. 1963.-Veal Infusion Broth surrounding a cellophane bag containing a 24-hr culture of Escherichia coli was inhibitory to an inoculum of the same strain when kept under an atmosphere of nitrogen plus CO(2). The i...

Bird and Hoevet (1) have described a procedure for measuring the vitamin Blz-binding capacity of protein mixtures derived from hog mucosa, based on the non-dialyzability of the protein-bound vitamin. They also observed that lysozyme would bind vitamin B1, as previously reported (3), but that it did not appear to retain the vitamin when dialyzed. However, the diffusibility of lysozyme through ce...

Two mold species, Stachybotrys chartarum and Aspergillus versicolor, were inoculated onto agar overlaid with cellophane, allowing determination of a direct measurement of biomass density by weighing. Biomass density, ergosterol content, and beta-N-acetylhexosaminidase (3.2.1.52) activity were monitored from inoculation to stationary phase. Regression analysis showed a good linear correlation to...

Background: Cheiloscopy, the study of lip prints, is an upcoming tool for the identification of persons. The lip print of every person is unique and can be used to fix personal identity. Aim: The prime objective of the present study was to ascertain whether the lip prints behold the potential for determination of sex of the individual from the configuration. Methods: The lip prints were recorde...

In the past, the endothelium was considered to be inert, described as a 'layer of nucleated cellophane', with only non-reactive barrier properties, such as presentation of a non-thrombogenic surface for blood flow and guarding against pro-inflammatory insults. However, it is now becoming clear that endothelial cells actively and reactively participate in haemostasis and immune and inflammatory ...
