    Assessment of gallbladder function using ceruletide in oral cholecystography (1985)
    Springer
    Abdominal imaging 10 (1985), S. 97-105

    Notes: Abstract A dose of 0.3 μg/kg body weight of ceruletide was assessed for its effect on gallbladder contraction and bile duct delineation following oral cholecystography. Nausea, vomiting, and abdominal pain sometimes occurred after ceruletide. No relationship was found after ceruletide administration between the radiologic appearances of the biliary tract and reproduction of the patients' biliary-type symptoms. Ceruletide cholecystography is regarded as an inaccurate investigation of biliary tract function.

    Equiconnectivity and cofibrations I (1981)

    Notes: Abstract In this paper and its sequel, we generalize the notion of local equiconnectivity (LEC) given in [1] to that of h local equiconnectivity. We study these notions systematically using the theory of cofibrations and h cofibrations. Some classical results of locally equiconnected spaces are extended and generalized.

    Comparisons of the Nucleotide Substitution Process Among Repetitive Segments of the α- and β-Spectrin Genes (1997)

    Notes: Abstract. The actin–cross-linking protein spectrin is a prominent component of the membrane cytoskeleton. Spectrin is a tetramer of two antiparallel αβ-dimers which share a unique and ancient gene structure. The α-spectrin and β-spectrin genes are composed primarily of tandemly repeated 106-amino-acid segments, each of which forms a triple α-helical coiled coil. Both the genes and the repeats themselves are homologous. The two genes are thought to be the result of a gene duplication event, and each gene is the product of duplications of the 106-amino-acid repeats. In this work we compare the process of molecular evolution across the repeated segments of the α- and β-spectrin genes. We find that the α-spectrin segments have, for the most part, evolved in a homogeneous fashion, while considerable heterogeneity is found among β-spectrin segments. Several segments with unique known functions are found to have evolved differently than the others. On the basis of heterogeneity of the evolutionary process, we suggest that at least one repeat has a unique function that has yet to be documented. We also present new statistical methods for comparing the evolutionary process between different regions of DNA sequences.

    The delayed neuropathic effects of nerve agents and some other organophosphorus compounds (1983)

    Notes: Abstract The in vitro inhibitory potencies of several nerve agents and other organophosphorus compounds against acetylcholinesterase (AChE) and neurotoxic esterase (NTE) have been compared. Although the I50s against AChE were about 0.1–1.0 nM for the nerve agents the I50s against NTE for sarin, soman and tabun were two to four orders of magnitude higher and VX had negligible activity. A series of bis[(ω-phenyl-n-alkyl]phosphorofluoridates inhibited both enzymes at 1.0–100 nM while ω-phenyl-n-alkyl NN-dimethylphosphoramidofluoridates were active at 0.1–10 μM. From the in vitro data it was predicted that nerve agents would cause delayed neuropathy only at doses greatly exceeding the LD50. In hens protected against acute toxicity by pretreatment with physostigmine, atropine and the oxime P2S, delayed neuropathy associated with high inhibition of NTE was found at 30–60 × LD50 for sarin but not at 38 × LD50 for soman or 82 × LD50 for tabun. At the maximum doses tested of the latter two compounds the inhibition of NTE was 55% and 66% respectively. The minimum neuropathic doses were calculated to be about 100–150 × LD50 for soman and tabun. As expected from in vitro data, neuropathy, associated with a high level of inhibition of NTE, was caused by one of the bis-phenylalkyl phosphorofluoridates at doses causing negligible acute toxicity. The required dose was 9X that for DFP although the compound was 300X more active against NTE in vitro suggesting that such compounds are rapidly degraded in vivo. The phenylalkyl NN-dimethylphosphoramidofluoridates produced prolonged acute signs of poisoning but they were not neuropathic at the maximum tolerable doses nor was the NTE greatly inhibited contrary to the prediction from the in vitro data. It is possible that the enantiomer responsible for the inhibition of NTE is preferentially degraded in vivo. Several other phosphoramidofluoridates inhibit NTE in vitro at 1.0–100 μM and a number of bicyclic phosphates were inactive at 23 μM. None of these compounds was tested in vivo.

    Notes: Abstract We present an extended polynomial remainder sequence algorithm XPRS for R[X] whereR is a domain. From this we derive a Berlekamp-Massey algorithm BM/R overR. We show that if (α) is a linear recurring sequence in a factorial domainU, then the characteristic polynomials for (α) form aprincipal ideal which is generated by a primitive minimal polynomial. Moreover, this generator ismonic when U[[X]] is factorial (for example, whenU is Z orK[X 1,X2,...,Xn] whereK is a field). From XPRS we derive an algorithm MINPOL for determining the minimal polynomial of (α) when an upper bound on the degree of some characteristic polynomial and sufficiently many initial terms of (α) are known. We also show how to obtain a Berlekamp-Massey type minimal polynomial algorithm from BM/U and state BM_MINPOL/K explicitly with a further refinement. Examples are given forU=Z, GF(2)[Y].
