Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures were determined by spectral methods (NMR, MS, IR). Among them, a novel compound, 4-hydroxyacetophenone-4-O-â-D-apiofuranosyl-(1f6)-O-â-D-glucopyranoside, was identified. Two test systems, DPPH free radical scavenging activity and radical cation ABTS•+ scavenging activity, were used to evaluate their ...

Tumor-, red marrow-, and organ-absorbed doses were calculated for patients receiving "'I-labeled monoclonal antibodies against carcinoembryonic antigen for either diagnosis or therapy. Ten patients with con firmed liver tumors who received doses ranging from 10.79 to 200 mCi were evaluated. Urine and blood samples were taken in order to determine total body and red marrow activity, respectively...

This paper presents in a unified manner mathematical properties of the second order derivatives of the overflow traffic from an Erlang loss system, assuming the number of circuits to be a nonnegative real value. It is shown that the overflow traffic function Â(a, x) is strictly convex with respect to x (number of circuits), with x ≥ 0, taking the offered traffic, a, as a positive real parameter...

/V-Nitniso-.V-methyhirea (NMU) is an effective carcinogen for the induction of mammary carcinoma in the rat. Tamoxifen (TAM), used as a chemopreventive agent to reduce tumor incidence, has been well studied using this model. We have utilized the rat mammary carcinoma model to assess the effect of TAM on preneoplastic changes. Fifty-day-old virgin female Sprague-Dawley rats were randomized by we...

The fine specificity analysis of two human monoclonal antibodies (AbFCMl and Ahi UM I ) reacting with gangliosides is described and their specificities are compared with analogous mouse monoclonal anti bodies (mAt)s). These two antibodies were generated from lymphocytes of melanoma patients by Epstein-Barr virus transformation followed by fusion with mouse myeloma NS-1. Using a wide variety of ...

One pot reactions of phenylphosphonic acid or phenylarsonic with cyclohexylamine led to two new organic-inorganic hybrid salts [C6H14N][C6H5PO3H.C6H5PO3H2.H2O] (1) and [(C6H14N)(C6H5AsO3H)] (2) which were investigated by single-crystal X-ray diffraction analysis. Salt 1 crystallizes in the monoclinic system, space group P21/nwith a = 12.3963 (4), b 6.1123 (2), c 28.2081 (8) Å, Ã...

 The foreign exchange market (FX market) accounts for 40% of the total volume of the world’s e-commerce by its own. Based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. The probability of loss in the FX market can be estimated by probability theory. The present paper intends to demonst...
