Cloning of a cDNA complementary to rat preputial gland [beta]-glucuronidase mRNA
(Elsevier, 1982-02-26)
Messenger RNA was isolated from rat preputial glands by guanidine HCl extraction, ethanol and salt precipitation, followed by chromatography on oligo(dT) cellulose. Double-stranded cDNA was synthesized from the mRNA and ...
Structure of human serum cholinesterase
(Wiley Subscription Services, Inc., A Wiley Company, 1988-10)
Human cholinesterase has recently been sequenced and cloned. It is a glycoprotein of 4 identical subunits, each subunit containing 9 carbohydrate chains and 3.5 disulfide bonds. Protein folding is likely to be very ...
Loss of calmodulin activity in cardiac sarcoplasmic reticulum after ischemia
(Elsevier, 1985-07-31)
Experiments were designed to evaluate whether cardiac ischemia affected the subcellular distribution of calmodulin activity. Major cellular fractions (nuclei, mitochondria, sarcoplasmic reticulum and cytosol) were isolated ...
Interstitial water patterns: A factor influencing the distributions of some lotic aquatic vascular macrophytes
(Elsevier, 1988-07)
The distributions of 9 species of aquatic vascular macrophytes were examined in relation to interstitial water patterns (based on temperature) in the beds of three northern Michigan (U.S.A.) streams. Ranunculus septentrionalis ...
Stimulation of prostaglandin E2 and thromboxane B2 production by human monocytes in response to interleukin-2
(Elsevier, 1987-08-31)
Interleukin 2 (IL-2) is a potent lymphokine involved in the regulation of immune responses and is classically regarded as a stimulus for the activation and growth of T-cells. Recent reports have demonstrated the IL-2 ...
Atrial natriuretic hormone is not elevated during dopamine induced natriuresis
(Elsevier, 1987-05-18)
To evaluate the possibility that atrial natriuretic hormone (ANH) is involved in dopamine induced natriuresis and diuresis, we studied five normal male volunteers. Each was studied on two occasions. During the first two ...
Analysis of organelle genomes in a somatic hybrid derived from cytoplasmic male-sterile Brassica oleracea and atrazine-resistant B. campestris
(Springer-Verlag, 1987-07)
An atrazine-resistant, male-fertile Brassica napus plant was synthesized by fusion of protoplasts from the diploid species B. oleracea and B. campestris . Leaf protoplasts from B. oleracea var. italica carrying the Ogura ...
Estimation of the affinity of naloxone at supraspinal and spinal opioid receptors in vivo: Studies with receptor selective agonists
(Elsevier, 1986-11-10)
The apparent affinity of naloxone at cerebral and spinal sites was estimated using selective mu [D-Ala2, Gly-ol5]-enkephalin (DAGO) and delta [D-Pen2, D-Pen5]enkephalin] (DPDPE) opioid agonists in the mouse warm water ...
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 ...
Time budgets of grassland herbivores: body size similarities
(Springer-Verlag, 1986-08)
The summer (May–September) time budgets of 14 generalist herbivore species living in the same grassland environment are presented in terms of various component activities (e.g., walking, feeding, resting, etc.). All the ...
