Other Comments: Conditions for the amplification reactions were as described in the reference except that samples were processed through 27 temperature cycles consisting of 1 min at 94°, 2 min at 55° and 1 min at 72°. Sizes of the alleles were determined by comparison to mp8 DNA sequencing ladders and were the averages of the sizes of the GT-strand and CA-strand bands. The dinucleotide repeat s...

Two new abietane type diterpenoids, namely seco-helioscopinolide (1) and 3b,7b-dihydroxy-ent-abieta-8,13-diene-12,16-olide (2) were isolated from the aerial parts of Euphorbia formosana Hayata together with helioscopinolide A (3), helioscopinolide B (4), helioscopinolide C (5) and ent-(5b,8a,9b,10a,12a)-12-hydroxyatis-16-ene-3,14-dione (6). The structures of compounds 1-6 were elucidated by ana...

Voltage regulator modules (VRM) need to have low output voltage ripple and tight efficiency power advanced microprocessors. This paper explains a phase shedding technique enhance its impact on ripple. In this study, analysis was done 4-phase buck converter which is having an input of 45-65 V delivers 9 V, 12A with switching frequency 200Khz. The control scheme suitable for applications such as ...

Chromatographic separation of a 70% aqueous methanol extract (AME) of Pongamia pinnata (Linn.) Pierre (Leguminosae) leaves has led to the isolation of two new isoflavonoid diglycosides, 4'-O-methyl-genistein 7-O-beta-D-rutinoside (2) and 2',5'-dimethoxy-genistein 7-O-beta-D-apiofuranosyl-(1"'-->6")-O-beta-D-glucopyranoside (6), and a new rotenoid, 12a-hydroxy-alpha-toxicarol (5), together with ...

The cyclization of dioxolanyl radicals, which were generated by the Barton tartrate-derived thiohydroxamate ester (mixed anhydride) procedure, with an indole nucleus has been explored. The products derived from these reactions have been identified and their chemistry investigated with the goal of uncovering new entries into enantiomerically pure, mitomycin-like structures. Thus, the photolysis ...

If, in addition, f(x) is continuous at x = a, then it is called completely monotonic over [a, b), with similar definitions for (a, b] and [a, b]. A function is absolutely monotonic if all its derivatives are non-negative. A detailed study of these concepts can be found, for example, in [11, Chapter IV]. Our chief concern here is for the standard case in which a = 0, b = + 00. For this, S. N. Be...

Andrographolide has been reported to possess a variety of pharmacological activities. In this study, we have investigated the effect of andrographolide on the production of TNF-alpha and IL-12 (Interleukin-12) in murine peritoneal macrophages. Andrographolide decreased TNF-alpha, IL-12a and IL-12b at mRNA level, and reduced the production of TNF-alpha and IL-12p70 proteins in a concentration-de...
