The effects of size of opening in vegetation and litter cover on seedling establishment of goldenrods ( Solidago spp.)
(Springer-Verlag, 1983-11)
We investigated the effects of size of opening in the vegetation and litter cover on seedling establishment of two species of goldenrods ( Solidago spp.) in an abandoned field in southwestern Michigan, U.S.A. Seeds of S. ...
Growth of three established cell lines on glass microcarriers
(Wiley Subscription Services, Inc., A Wiley Company, 1983-05)
Three established cell lines were examined for growth on a newly developed microcarrier which consists of glass beads. The cells were simultaneously exmined for growth on commercially available microcarriers made from ...
Effects of denervation on 3 H-fucose incorporation by odontoblasts in the mouse incisor
(Springer-Verlag, 1983-03)
The present study was designed to determine the effects of denervation on glycoprotein synthesis in the predentinal matrix of the mouse incisor. The inferior alveolar nerve (IAN), superior cervical ganglion (SCG) or both ...
Impaired lymphocyte function in depressive illness
(Elsevier, 1983-07-18)
Mood states and immunity may be related. To investigate the immune status of patients with primary depressive illness, we compared lymphocytic responses to three different mitogens in 26 drug-free depressed patients and ...
Aging effect on nectar production in two clones of Asclepias syriaca
(Springer-Verlag; Springer-Verlag GmbH & CO., 1983-01)
In common milkweed ( Asclepias syriaca ), flower nectar volumes, concentration and sugar production varied according to the age of the sampled blossoms. In individual blossoms, nectar production peaked daily at 0800 hr. ...
The fluorescence response of chlortetracycline-loaded human neutrophils is modulated by prostaglandin E1, but not by cyclic nucleotides
(Elsevier, 1983-10-31)
Human neutrophils preloaded with chlortetracycline, commonly used as a probe of membrane-bound calcium, demonstrate a prompt decrease in fluorescence when exposed to surface stimuli such as the chemotactic peptide ...
Identification of N5-methyl-N5-formyl-2,5,6-triamino-4-hydroxypyrimidine as a major adduct in rat liver DNA after treatment with the carcinogens, N,N-dimethylnitrosamine or 1,2-dimethylhydrazine
(Elsevier, 1983-01-27)
A major and previously undetected carcinogen-DNA adduct was found in the livers of rats given N,N-dimethylnitrosamine or 1,2-dimethylhydrazine. This adduct, which accounted for 55% of the total methyl residues in DNA at ...
Human adenine phosphoribosyltransferase: Characterization from subjects with a deficiency of enzyme activity
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-12)
Adenine phosphoribosyltransferase (APRT) was characterized with respect to specific activity and immunoreactive protein (CRM) levels in hemolysate from 18 members of an APRT-deficient kindred. In addition, lymphoblastoid ...
The comparison between enkephalin-like and dynorphin-like immunoreactivity in both monkey and human globus pallidus and substantia nigra
(Elsevier, 1983)
The distribution of [Met]-Enkephalin and Dynorphin-like immunoreactivity were studied in the monkey and human globus pallidus and substantia nigra. These distributions were compared to those seen in these structures of the ...
4-Methyleneglutamine synthetase: A new amide synthetase present in germinating peanuts
(Elsevier, 1983-03-16)
Enzymatic activity which catalyzes the synthesis of 4-methyleneglutamine from 4-methyleneglutamic acid + ammonia was detected in and partially purified from cotyledons of peanut seeds germinated 5 to 7 days. This activity ...
