1. 1. Classification of muscle stretch receptor afferents in humans

   Författare :Benoni B. Edin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle spindles; Golgi tendon organs; Classification of muscle receptors; Microneurography; Human hand; Stretch sensitization; Voluntary contraction; Static position sensitivity; Fusimotor control;

   Sammanfattning : 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. LÄS MER

3. 2. Functional characterisation of the CAG polymorphism in the androgen receptor- in vitro and in vivo

   Författare :Hannah Nenonen; Diabetes - öpatofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; androgen receptor; polymorphism; CAG polymorphism; androgen receptor activity; infertility; prostate cancer; androgen receptor function;

   Sammanfattning : 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. LÄS MER

4. 3. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

   Författare :Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

   Sammanfattning : 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. LÄS MER

5. 4. Genetic, environmental and life-style effects on androgen receptor function

   Författare :Christel Björk; Malmö Molekylärgenetisk reproduktionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproductive function; smoking; 4 .4-DDE; persistent organic pollutants; prostate cancer; Androgen receptor; prostate specific antigen; CAG polymorphism; TCDD; aryl hydrocarbon receptor; CB-153;

   Sammanfattning : 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. LÄS MER

7. 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

   Författare :Sten Theander; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; lobster; stretch receptor neuron; leak current; Q-current; K-Cl cotransporter; A-current; mathematical model; excitability; GABA channel; neurophysiology; ion regulation; neuropsykologi; Neurologi; neurofysiologi;

   Sammanfattning : 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+.
