Growth of [lambda] variants with added or altered promoters in N-limiting bacterial mutants: Evidence that an N recognition site lies in the PR promoter
(Elsevier, 1976-05)
Transcription of the [lambda] genome, initiating at the early rightward promoter (PR), traverses the cII-O-P operon and extends through the Q gene. In the absence of the [lambda] N function, this transcription is prematurely ...
Effects of the antiestrogens, MER-25 and CI 628, on rat and hamster lordosis
(Elsevier, 1976-09)
Antiestrogens were used to test the hypothesis that estrogen exerts a "maintenance," as well as a "priming," effect on rat and hamster sexual receptivity as it apparently does for guinea pigs. MER-25 (75 or 150 mg/kg) ...
Immunochemical studies on methyl [alpha]- and methyl [beta]-glucosaminide-azoprotein conjugates
(Elsevier, 1976-09)
Conjugates consisting of methyl 2(p-azobenzamido)2-deoxy-[alpha]--glucopyranoside and methyl 2(p-azobenzamido)-2-[beta]--glucopyranoside coupled to bovine serum albumin were used as synthetic antigens. Rabbits immunized ...
An N-acetyl--glucosamine binding lectin from Bandeiraea Simplicifolia seeds
(Elsevier, 1976-11)
A second lectin with a high activity for nonreducing 2-acetamido-2-deoxy-[alpha]--glucopyranosyl residues has been isolated from the seed extracts of Bandeiraea simplicifolia by affinity chromatography on chitin. The lectin ...
Molecular aspects of control in epidermal differentiation
(Kluwer Academic Publishers; Dr. W. Junk b.v. Publishers ; Springer Science+Business Media, 1976-09)
The mammalian epidermis is organized into layers of structurally different cells—the basal, spinous, granular and cornified layers—which represent steps in the differentiative process that terminates in cornification and ...
Synthesis and properties of 35S, 14C and 3H labeled S-alkyl glycerol ethers and derivatives
(Elsevier, 1976-07)
Radioactive S-alkyl glycerol ethers have been synthesized with 35S, 14C and 3H labels as well as 3H/35S double labels.The synthesized compounds were converted to various derivatives which can serve to characterize the ...
The effect of methionine on the uptake, distribution, and binding of the convulsant methionine sulfoximine in the rat
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1976-02)
The effect of methionine on the uptake, distribution, and binding of the convulsant methionine sulfoximine (MSO) in 7 rat brain regions, the spinal cord, the liver, and the kidney was investigated. The administration of ...
Large unit red cell cryopreservation with hydroxyethyl starch
(Elsevier, 1976-10)
Full units of red blood cells frozen with 14% hydroxyethyl starch (HES) yield cell recoveries near 97% and saline stabilities greater than 80%. Potassium leaves the cells during the freeze-thaw cycle and increases the ...
