ofthe various factors that go into the computation better; it also segregates the least reliable and error-prone model-dependent components into terms that can be identified and minimized.

C —¿ > T transitions at CpG sites are the most prevalent mutations found in the p53 tumor suppressor gene in human colon tumors and in the germline (Li-Fraumeni syndrome). All of the mutational hot spots are methylated to 5-methylcytosine, and it has been hypothesized that the majority of these mutations are caused by spontaneous hydrolytic deamination of this base to thymine. We have previou...

â â â  moral values of shanfara in , lamyat- alarab ode â  â  somayeh kazemi * â  jafar delshad ** â  â  in this descriptive-analytic study, the researchers aimed to study the verses of lamyat- al arab and examine the moral values and mental pains which made the poet shanfara express such values. â  this survey has been affected by a hadith that indicates the tendency of the poet to the moral v...

In an attempt to better understand breast tumors sensitivity or resis tance to anticancer drugs, the main drug-metabolizing enzyme systems were evaluated in both breast tumors and their corresponding peritumoral tissues in 12 patients. The following enzymes were assayed by Western blot: cytochromes P-4SO (1A1/A2, 2B1/B2, 2C8-10, 2E1, 3A4); glutathione .S'-transferases (GST-a, -u, and -TI); and ...

Let A be an abelian variety,  be the dual abelian variety. The Fourier-Mukai transform is an equivalence between the derived categories of coherent sheaves Db(A) and Db(Â). Notice that there is a ”symplectic” line bundle LA on (Â×A)2, namely, LA = p14P⊗√∈∋P where P is the Poincaré line bundle on Â×A, such that the standard embeddings A ⊂ Â×A and  ⊂ Â×A are ”lagrangian” with respect to LA, i.e...

The hypothesis that the naturally occurring analgesic peptide, â-endorphin, is released in the brain in response to pain had never been directly validated. In this study, we applied a brain microdialysis method for monitoring â-endorphin release in vivo, to test this hypothesis in the brains of conscious, freely moving rats. Herein we first show that endogenous â-endorphin can be measured in vi...

In the Bargmann representation of quantum mechanics, physical states are mapped into entire functions of a complex variable z, whereas the creation and annihilation operators â and â play the role of multiplication and differentiation with respect to z, respectively. In this paper we propose an alternative representation of quantum states, conjugate to the Bargmann representation, where the rol...

homoalcophosphamide by the procedure of Corey and Kim (7) gave diethylaldophosphamide and diethylhomoaldophos phamide, respectively (Chart 2). Diethylaldophosphamide was characterized by mass spectral analysis [m/e 283, 1 Cl, M2— CH2C1@; m/e 192, no Cl, M —N(CH2CH2C1)2] and by positive qualitative tests as an aldehyde and an alkylating agent. Complete purification of diethylaldophosphamide ...
