In this paper, 3and 4-secure codes are constructed from combinatorial designs. Both constant weight and non-constant weight codes are shown.

Alkylating agents have been studied extensively both for their biological effects and for their mode of action. There have been over the past 25 years a veritable deluge of reviews, often focusing on a single aspect or agent or adduct. It can be easily noted that certain analytical techniques were widely used. These were either neutral heating of DNA which liberates 3and 7alkyl purines and/or h...

The shortand longer-term effectiveness of a brief, multidisciplinary itch-coping group training scheme in adults with atopic dermatitis was evaluated. Clinical severity scores (Eczema Area and Severity Index) and validated self-report measures were obtained in a waitinglist control condition (n = 30) and a treatment condition (n = 61) at preand post-treatment and in the treatment condition at 3...

Awayda, Mouhamed S. Regulation of the epithelial Na1 channel by intracellular Na1. Am. J. Physiol. 277 (Cell Physiol. 46): C216–C224, 1999.—The hypothesis that the intracellular Na1 concentration ([Na]i) is a regulator of the epithelial Na1 channel (ENaC) was tested with the Xenopus oocyte expression system by utilizing a dual-electrode voltage clamp. [Na]i averaged 48.1 6 2.2 meq (n 5 27) and ...

The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...

3and 4-monoesterified protocatechuic acid methyl ester (5 and 7 respectively) have been synthesised from quinic acid by a high yields biomimetic rearrangement.

Glucose dehydrogenase (GlcDH) is the rate-limiting catalyst for microbial conversion of glucose to the important organic acid 2-ketogluconic acid (2KGlcA). In this study, a D-glucose dehydrogenase was purified from the industrial 2KGlcA producer Arthrobacter globiformis C224. After four purification steps, the GlcDH was successfully purified over 180 folds and specific activity of 88.1 U/mg. A ...

The manuscript describes some impacts of eastern European biomass burning on some ambient air monitoring stations located in Finland in the spring and summer of 2006. The paper follows the familiar model of monitoring and interpretive analysis. In my opinion, however, there is a difference between monitoring, monitoring with valueadded analysis, and research. I believe ACP should be an outlet f...

On the basis of evidence presented or cited in a previous article (see Reference 1 for Paper I), the group-specific C-polysaccharide of Group A hemolytic streptocci is a polymer of L-rhamnose and N-acetyl-n-glucosamine in which the methylpentose units occur as 3and 2,3-substituted, a-linked saccharides with terminal P-linked hexosamine molecules and possibly intracatenary hexosamine. The study ...
