A comparison of proteins and peptides as substrates for microsomal and solubilized oligosaccharyltransferase
(Elsevier, 1994-11)
A chemoenzymatic synthesis of homogeneous neoglycoproteins and glycopeptides was explored using oligosaccharyltransferase isolated from yeast. Neither the microsomal form nor the solubilized form of the enzyme catalyzed ...
Benzimidazole ribonucleosides: Observation of an unexpected nitration when performing non-aqueous diazotizations with t-butyl nitrite
(Elsevier, 1992-09)
Mild, non-acidic conditions used in the non-aqueous diazotization of a 2-aminobenzimidazole nucleoside with t-butyl nitrite gave an unexpected 4-nitrobenzimidazol-2-one nucleoside which was not formed when primary alkyl ...
Computation of multilocus prior probability of autozygosity for complex inbred pedigrees
(Wiley Subscription Services, Inc., A Wiley Company, 1997)
Homozygosity mapping is a very powerful method for mapping rare recessive diseases in humans. In many applications, it is often desirable to compute prior (or unconditional) multilocus probability of autozygosity for inbred ...
Human chromosome 17 NotI linking clones and their use in long-range restriction mapping of the Miller-Dieker chromosome region (MDCR) in 17p13.3
(Elsevier, 1990-06)
A NotI linking library constructed from flow-sorted human chromosome 17 material was screened to aid in construction of a long-range restriction map of the Miller-Dieker chromosome region (MDCR) in 17p13.3. A total of 66 ...
Triple Junction Mobility: A Molecular Dynamics Study
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle ...
Thermodynamics of alkali alkanoates IX. Heat capacity and thermodynamic functions of lithium 2-methylpropanoate at temperatures from 7 K to 535 K
(Elsevier, 1993-10)
The heat capacity of lithium 2-methylpropanoate was measured by equilibrium adiabatic calorimetry at temperatures, T from 7 K up to 350 K and by d.s.c. from 330 K through melting to 535 K. A small diffuse hump was observed ...
The effects of menstrual phase and nicotine abstinence on nicotine intake and on biochemical and subjective measures in women smokers: a A preliminary report
(Elsevier, 1992-11)
Nicotine intake, menstrual and smoking withdrawal symptomatology, and baseline cortisol and MHPG were assessed in nine women smokers under conditions of ad lib smoking and overnight abstinence in three menstrual phases ...
Effects of neuropeptide Y, insulin, 2-deoxyglucose, and food deprivation on food-motivated behavior
(Springer-Verlag, 1995-08)
The current study demonstrates the ability of neuropeptide Y (NPY) to increase break points under a progressive ratio 1 (PR1) reinforcement schedule. An initial response resulted in delivery of a food reinforcer (45 mg ...
Selective multiple methylene insertion reactions mediated by iodomethylzine iodide: Mechanistic considerations and synthetic applications
(Elsevier, 1991-04-15)
The reaction of alkynylcoppers 1 with an excess of iodomethylzinc iodide selectively furnishes the quadruple methylene insertion copper organometallics 2 in fair to good yields. The mechanism of the reaction has been ...
