An infertile man presented a spermiogram in which 100% of the spermatozoa displayed separation of head from tail at the level of the proximal centriole. Most tails were normally structured and ended anteriorly with the proximal centriole covered by a continuous plasma membrane. In a small percentage of tails a rudimentary connecting piece was surrounded by(More)
The input from the medial geniculate nucleus of the thalamus (MGN) to the lateral amygdala is known to be important in the regulation of fear and anxiety. Modulation of this pathway may be useful for the treatment of anxiety disorders. We set out to determine whether simple extracellular electrophysiological techniques could be used to study pharmacological(More)
Acetylcholinesterase inhibitors (AChE-Is), galantamine, physostigmine and tacrine, enhance central levels of synaptic acetylcholine. Galantamine and physostigmine, but not tacrine, exhibit allosteric potentiation ligand (APL) properties on nicotinic acetylcholine receptors. The purpose of this study was to investigate whether AChE-Is with nicotinic(More)
A 33-year-old man had azoospermia and tubular atrophy as in the Klinefelter syndrome but short stature. He had a 46,X,t(X/Y) (Xqter lead to p22.3::Yp11 lead to Yqter) translocation and was H-Y antigen-positive. This excludes one of the genes controlling H-Y antigen from the terminal portion of the short arm of the Y chromosome. This case and the two similar(More)
INTRODUCTION Unwanted effects of drugs on neurobehavioural and cardiovascular functions are normally assessed in separate studies and using different animals. A new model using dogs which allows for the integration of these assessments into a single study was established and validated, adopting the most sophisticated technologies for both monitoring(More)
INTRODUCTION Unwanted effects of drugs on neurobehavioural and cardiovascular functions are normally assessed in separate studies and using different animals. The purpose of this study was to validate, in the monkey, a model that incorporates the neurobehavioural assessment into the Safety Pharmacology cardiovascular study, allowing for an integrated(More)
INTRODUCTION The objective of this study was to describe an optimised neurobehavioural observation battery in the beagle dog and to demonstrate that it can be used for an integrated assessment of cardiovascular and neurobehavioural functions within a single Safety Pharmacology study. METHODS A standardised and detailed observation battery was established(More)
