Effects of neuropeptide Y, insulin, 2-deoxyglucose, and food deprivation on food-motivated behavior
(Springer-Verlag, 1995-08)
The current study demonstrates the ability of neuropeptide Y (NPY) to increase break points under a progressive ratio 1 (PR1) reinforcement schedule. An initial response resulted in delivery of a food reinforcer (45 mg ...
Design of molecular architectures for polymeric mesophase formation
(Wiley Periodicals, Inc.Hüthig & Wepf Verlag, 1995-07)
Based on the tendency of low molar mass liquid crystals composed of extended mesogens symmetrically disubstituted with long n ‐alkoxy substituents to exhibit smectic C mesophases, we have proposed that SCLCPs with laterally ...
Competitive and uncompetitive N -methyl- d -aspartate antagonist discriminations in pigeons: CGS 19755 and phencyclidine
(Springer-Verlag, 1995-03)
The purpose of the present studies was to examine representative uncompetitive and competitive NMDA antagonists, as well as the glycine/NMDA antagonist, HA 966, in pigeons trained to discriminate either PCP or CGS 19755 ...
Continuous medium perfusion leads to long-term cell viability and oxygen production in high-density photobioreactors
(Kluwer Academic Publishers; Chapman & Hall, London ; Springer Science+Business Media, 1995-11)
A light-emitting diode-based photobioreactor (LED-based PBR) operated in a continuous perfusion mode with a perfusion rate of 3 to 6 reactor volumes a day supports high-density algal cultures, of cell concentrations up to ...
“Escape” of aldosterone production in patients with left ventricular dysfunction treated with an angiotensin converting enzyme inhibitor: Implications for therapy
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-02)
Despite the findings in randomized trials of a significant effect of angiotensin-converting enzyme (ACE) inhibitors in reducing morbidity and mortality of patients with symptomatic left ventricular dysfunction, the morbidity ...
Aggression, anxiety and vocalizations in animals: GABA A and 5-HT anxiolytics
(Springer-Verlag, 1995-09)
A continuing challenge for preclinical research on anxiolytic drugs is to capture the affective dimension that characterizes anxiety and aggression, either in their adaptive forms or when they become of clinical concern. ...
Current benzodiazepine issues
(Springer-Verlag, 1995-03)
This article deals with some of the recent evidence bearing on the issues of the liability of benzodiazepines to lead to abuse, dependence, and adverse behavioral effects. Reviews of epidemiological, clinical and experimental ...
Subcellular distribution of terminal α-D- and β-D-galactosyl residues in Ehrlich tumour cells studied by lectin-gold techniques
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1995-04)
We have studied by high resolution in situ light and electron microscopic lectin-gold techniques the subcellular distribution of α- d -Gal residues using the Griffonia simplicifolia I-B 4 isolectin and compared it with ...
The development of sensitization to the psychomotor stimulant effects of amphetamine is enhanced in a novel environment
(Springer-Verlag, 1995-02)
Two experiments were designed to assess the effect of a “novel” environment on the development of sensitization to the psychomotor activating effects of d -amphetamine. In the first experiment, rats with a unilateral ...
Long-term effects of brief antihypertensive treatment on systolic blood pressure and vascular reactivity in young genetically hypertensive rats
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-06)
Recent studies have shown that angiotensin converting enzyme (ACE) inhibitor treatment in young spontaneously hypertensive rats (SHR) reduces blood pressure into adulthood. This study explored changes in vascular reactivity ...
