A simple method for the purification of human peripheral blood monocytes : A substitute for Sepracell-MN
(Elsevier, 1991-11-22)
Sepracell-MN has provided a simple, rapid means of isolating peripheral blood monocytes. However this product is no longer available. Consequentially we have developed a Percoll gradient wich matches Sepracell-MN in ...
Effect of medium osmolarity on hybridoma growth, metabolism, and antibody production
(Wiley Subscription Services, Inc., A Wiley Company, 1991-04-25)
No Abstract.
New shuttle vectors for direct cloning in Saccharomyces cerevisiae
(Elsevier, 1991-07-31)
We have constructed new shuttle vectors to facilitate the screening of recombinant plasmids after direct transformation of yeast cells. The vectors are pBluescript-based shuttle vectors in which the lacZ marker has been ...
Sweet taste preference in women smokers: Comparison with nonsmokers and effects of menstrual phase and nicotine abstinence
(Elsevier, 1991-12)
Cigarette smokers weigh less than comparably aged nonsmokers, and many gain weight following cessation. Though some evidence suggests that nicotine reduces food intake, with a selective effect on sweet-tasting foods, the ...
Purification and characterization of cytochrome P450 2E2 from hepatic microsomes of neonatal rabbits
(Elsevier, 1991-12)
The alcohol-inducible P450 2E subfamily in the rabbit has two known members that differ in only 16 amino acid residues scattered throughout the polypeptide chain. P450 2E1 has been thoroughly characterized, and is known ...
Naloxone blockade of amphetamine place preference conditioning
(Springer-Verlag, 1991-06)
Amphetamine and naloxone were examined in place conditioning, in order to study possible interactions between endogenous opioids and catecholamines in reinforcement. After initial preferences were determined, animals were ...
Induction of NF-[chi]B during monocyte differentiation is associated with activation of HIV-gene expression
(Elsevier, 1991)
Cells of the monocyte-macrophage lineage are important targets of HIV infection. We report here that the phenotypic differentiation of monocyte cell lines induced by phorbol esters or tumour necrosis factor [alpha] ...
Sensitization to systemic amphetamine produces an enhanced locomotor response to a subsequent intra-accumbens amphetamine challenge in rats
(Springer-Verlag, 1991-05)
Repeated amphetamine (AMPH) administration into the nucleus accumbens does not enhance (sensitize) the locomotor activity produced by a subsequent systemic AMPH challenge. We report here, however, that pretreatment with ...
Heat capacity and thermodynamic properties of synthetic heazlewoodite, Ni3S2, and of the high-temperature phase Ni3±xS2
(Elsevier, 1991-01)
The heat capacity of synthetic heazlewoodite (Ni3S2) was measured over the temperature range 5 K to 350 K by equilibrium adiabatic calorimetry and compared with earlier results. High-temperature results on this phase and ...
Effects of single and repeated electroconvulsive therapy sessions on plasma ACTH, prolactin, growth hormone and cortisol concentrations
(Elsevier, 1991)
To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately ...
