1. Classification of muscle stretch receptor afferents in humans
Abstract : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. READ MORE

2. Functional characterisation of the CAG polymorphism in the androgen receptor- in vitro and in vivo
Abstract : The androgen receptor (AR) is the mediator of androgen actions. In the AR coding region there is a polymorphic CAG repeat encoding a stretch of the amino acid glutamine (Q). The repeat length modulates receptor activity and is normally distributed between 10-30 CAG with a median length of 22 repeats in white men. READ MORE

3. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle
Abstract : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. READ MORE

4. Genetic, environmental and life-style effects on androgen receptor function
Abstract : Androgens regulate male reproductive function and their effects are mediated through the androgen receptor (AR). The AR gene contains a polymorphic CAG repeat, encoding a stretch of glutamines, affecting the transcriptional activity of the AR. READ MORE

5. Applying the Pump and Leak Hypothesis. An experimental and theoretical investigation of the principles of ion regulation and excitability in the crustacean stretch receptor neuron
Abstract : An invertebrate nerve cell preparation, the lobster stretch receptor neuron, was investigated with respect to maintenance of its resting voltage, intracellular ion concentrations and excitability using voltage clamp technique and ion-selective microelectrodes. It was found that the resting voltage (-65 mV) of microelectrode impaled cells is caused by (a) a homogenous population of K+ channels which we denoted as leak channels (b) an electrogenic and voltage-dependent Na-K pump current and (c) an inward microelectrode-induced "impalement" current carried mainly by Na+.
