AIMS To test the hypothesis that a correct qualitative assessment of axillary nodal status can be established by examining only a limited number of lymph nodes. METHODS Slides from 499 pN1 or pN0 axillary dissection specimens relating to symptomatic breast cancer cases operated on at our institution between 1991 and 1996 were reviewed. Nodes were ranked in descending order on the basis of the...

We use the finite lattice method to calculate the radius of gyration, the first and second area-weighted moments of self-avoiding polygons on the square lattice. The series have been calculated for polygons up to perimeter 82. Analysis of the series yields high accuracy estimates confirming theoretical predictions for the value of the size exponent, ν = 3/4, and certain universal amplitude comb...

The concept of idolatry in the Bible is powerful and complex, diverse and problematic. Even though, as Halbertal and Margalit note, ‘the central theological principle in the Bible is [the refutation of] idolatry’ (10), it is ironic that the ‘category that is supposed to be the firmest and strictest of all... [exhibits] an astonishing fluidity’ (250). A theological treatment of the subject must ...

We propose a concept of intellectual values as (a) shared within a group and defined by the extent to which intellectual engagement is regarded as worthwhile to the group’s interests, (b) supported by an epistemological belief system, and (c) an important dimension of sociocultural practice and learning. A series of studies is described in which assessments of intellectual values and epistemolo...

A sensory evaluation study was performed at UC Davis to determine if taste differences could be detected among several English walnut (Juglans regia) cultivars. Differences were tested using the duo-trio method, in which 'Hartley' was compared to seven other cultivars. No differences were found when 'Hartley' was compared to 'Vina', 'Scharsch Franquette' and 'Mayette', however 'Chandler', 'Chic...

The current study aimed to develop carbomer based hydrogel dressings, incorporating ethanolic extracts of Rosmarinus officinalis aerial parts, Achillea millefolium and Calendula flowers. pharmaceutical properties the obtained hydrogels, as well their texture antimicrobial activity, were further evaluated. Five wound dressing formulations on carbopol prepared. addition formulation slightly lower...

The effects of Ca2+ (0–75 mg/g pectin) and sucrose (0–40%, w/w) or sweeteners (0.1, 0.05% stevia saccharin) pH (3.0, 4.5, 6.8) on the rheological properties gels formed with sunflower pectins purified by conventional method (Conv-pectin), microfiltration (MF-pectin) ultrafiltration (UF-pectin) were investigated. main objective was to develop alternative low-calorie pectin without altered gelati...
