Facilitation of Pavlovian conditioned cardiodecelerations following preshock in immobilized rats
(Elsevier, 1975-12)
Two experiments are reported that examine the effects of unsignalled, inescapable prior shock exposure (PSE) on shock-motivated Pavlovian conditioned heart rate (HR) decelerations in rats. Both studies involved 2 CS-US ...
Immunochemical staining of the rat adenohypophysis in organ culture
(Wiley Subscription Services, Inc., A Wiley Company, 1975-01)
Rat anterior pituitaries were cytologically studied following cultivation in organ culture, with and without the addition of hypothalamic and cortical extracts. Although five distinct cell types could be identified with ...
Use of [1 or 3-3H, U-14c]glucose to estimate the synthesis of glycerolipids via acyl dihydroxyacetone phosphate
(Elsevier, 1975-07-22)
SummaryBHK-21-cl3 fibroblasts were incubated with [1-3H, U-14c]glucose or [3-3H, U-14c]glucose to produce intracellular [3H]NADPH via the phosphogluconate pathway. 3H and 14C were then determined at the three positions of ...
Immunological cross-reaction of bovine growth hormone (NIH-GH-B8) with the antiserum to the bovine diabetogenic protein
(Elsevier, 1975-04-01)
1. 1. The immunological cross-reaction of bovine growth hormone (BGH, NIH-GH-D8) with the antiserum to the bovine diabetogenic protein (BDP) has been determined to be the result of contamination of the BGH preparation with ...
Contractile and histochemical properties of regenerating cross-transplanted fast and slow muscles in the rat
(Springer-Verlag, 1975-09)
The soleus (SOL) or extensor digitorum longus (EDL) muscles of month-old rats were denervated for 14 days and then cross-transplanted so that the fast muscle was placed into the bed of the slow muscle and vice versa. At ...
Gastric function in Caiman crocodilus (Crocodylia: Reptilia)--II. Effects of temperature on pH and proteolysis
(Elsevier, 1975-06-01)
1. 1. In Caiman crocodilus, the pH of the gastric secretions during digestion may reach 1[middle dot]2 in specimens kept between 20 and 30[deg]C. C. crocodilus feeds and digests at 15[deg]C, but the pH of gastric secretions ...
A general analysis of resource allocation by competing individuals
(Elsevier, 1975-08)
The analysis presented in this paper is constructed to determine the pattern of resource allocations among competing individuals of the same and/or different species in some defined habitat. Competing individuals have at ...
The time course of saccadic eye movements in goldfish
(Elsevier, 1975-03)
Spontaneous saccadic eye movements (2-25[deg]) made by goldfish have an initial brief acceleration, followed by a more prolonged deceleration, and occasionally a terminal phase during which the velocity reverses sign ...
Analysis of polynomial functions for determining maximum or minimum conditions in biological systems
(Elsevier, 1975)
1. When physiological condition is curvilinearly related to environmental conditions, the "optimum" environmental condition is frequently determined by intersecting two straight lines.2. Errors in this method are discussed, ...
