BACKGROUND There is an increasing interest to seek new enzyme preparations for the development of new products derived from bioprocesses to obtain alternative bio-based materials. In this context, four non-commercial lipases from Pseudomonas species were prepared, immobilized on different low-cost supports, and examined for potential biotechnological applications. RESULTS To reduce costs of e...
In a recent communication (l), indirect evidence was offered for the assertion that a radioactive polybromide, prepared from the unsaturated fatty acids of rats which had been fed methyl linolenate-l-C’*, was derived, not from arachidonic acid, but from a derivative of linolenic acid, possibly an eicosapentaenoic acid. In a further consideration of this problem, it was apparent that an analysis...
To add to the existing evidence that comes mostly from White populations, we conducted a nested case-control study to examine the association between sex hormones and breast cancer risk within the Multiethnic Cohort that includes Japanese American, White, Native Hawaiian, African American, and Latina women. Of the postmenopausal women for whom we had a plasma sample, 132 developed breast cancer...
Assessment of anticoagulation status during cardiac surgery can be valuable for novel therapeutics, including direct thrombin inhibitors. The ecarin clotting time (ECT) has been reported to be sensitive for monitoring of bivalirudin in cardiac surgery but is not commercially available. The activated clotting time (ACT), commonly used for heparin monitoring, may display a lack of sensitivity to ...
The coefficient of apparent ileal digestibility (CAID) of DM, gross energy (GE), N, and amino acids (AA) of 6 soybean meal (SBM) samples were compared in 21-d-old broilers. In addition, the digestibility of DM and N of diets that contained these SBM were tested in vitro. Four of the SBM were of South American origin, had a CP content varying from 45.2 to 47.2% and a trypsin inhibitor activity (...
The previous paper in this series (Thompson, 1955) reported some amino acid sequences in lysozyme which were deduced from the structures of a number of small peptides isolated from partial acid hydrolysates by displacement chromatography on ion-exchange resins and further fractionation on paper chromatograms. Despite the success achieved by Partridge and co-workers (see Partridge & Brimley, 195...
Increased attention has been focused on the potential significance of the variations in the qualitative and quantitative composition of connective tissue ground substance. Changes in tissue content of acid mucopolysaccharides are difficult to define since existing quantitative methods are generally recognized as inadequate. Moreover, these methods are laborious and require large amounts of star...
1.08, CHCl3). To a suspension of CuBr (13 mg, 0.1 mmol) in ether (1 mL) at 0 "C was added allylmagnesium bromide (2.2 mL, 0.48 mmol), followed by the above-obtained tosyl-triflate 15 in ether (3 mL), and the reaction mixture was stirred at the same temperature for 3.5 h. Then n-Bu2CuLi (1.4 mmol) in ether (3 mL) was introduced and the mixture was stirred at room temperature for 12 h. Usual work...
Koshi Saito, Yoshiyuki Takahashi, and Mizu Wada Department of Applied Chemistry, Faculty of Engineering, Tokai University, 1117 Kitakaname, Hiratsuka-shi, Kanagawa-ken 259-12, Japan Z. Naturforsch. 40c, 819-826 (1985); received August 12, 1985 Carthamin Synthesis, Safflower Seedling, Catalytic Property An enzyme associated with carthamin formation in Carthamus tinctorius L. (carthamin-synthesiz...
In the course of our screening for new antibiotics, we have found heneicomycin (antibiotic A21A)1) in culture broth of a newly isolated strain of Streptomyces filipinensis, designated NRRL #11044 (MA-4581 in the Merck & Co., Inc. culture collection). From the physico-chemical and biological properties described in this communication, heneicomycin is considered to be equivalent to 3-deoxyaurodox...
