INTRODUCTION Open crus fracture is still difficult in clinical treatment because of the delayed fracture union and high rate of nonunion after the operation. A consensus has been reached that mechanical stress can promote fracture healing. We independently developed a stress stimulator, which can provide longitudinal pressure for the fixed fracture end of the lower legs to promote fracture heal...

the objective of this study was to examine the correlation between both midfollicular fsh/lh ratio and number(s) of follicles with ovarian hyperstimulation syndrome (ohss) in patients with polycystic ovarian syndrome (pcos). this was carried out in ivf unit at mirza kouchak khan hospital. to induce ovulation, pcos patients were stimulated with gonadotropines. fifty four pcos patients with norma...

A I3-element tactile array stimulator has been developed for research into the spatial-response properties of cortical neurons in the finger areas of the somatosensory cortex, the region of the cerebrum that receives and processes the somatic senses (touch, temperature, and pain). The tactile array consists of precision limited-motion, linear-displacement motors that are individually controlled...

OBJECTIVE To measure the effect of the Odstock Dropped Foot Stimulator (ODFS), a common peroneal stimulator, on the effort and speed of walking. DESIGN A randomized controlled trial. SUBJECTS Hemiplegic patients who had suffered a single stroke at least six months prior to the start of the trial whose walking was impaired by a drop-foot. INTERVENTIONS The treatment, functional electrical ...

STUDY QUESTION Is ovarian tissue cryopreservation using vitrification followed by in vitro activation (IVA) of dormant follicles a potential approach for infertility treatment of patients with primary ovarian insufficiency (POI)? SUMMARY ANSWER Our vitrification approach followed by IVA treatment is a potential infertility therapy for POI patients whose ovaries contain residual follicles. W...

BACKGROUND AND OBJECTIVES There are several methods to locate the femoral nerve in the perivascular inguinal space, being the most common the use of a peripheral nerve stimulator. This study aimed at evaluating femoral nerve block performed with peripheral nerve stimulator as compared to the loss of resistance to air technique, both by single injection or with catheter insertion. METHODS Sixt...

A programmable optical stimulator for Drosophila eyes is presented. The target application of the stimulator is to induce retinal degeneration in fly photoreceptor cells by exposing them to light in a controlled manner. The goal of this work is to obtain a reproducible system for studying age-related changes in susceptibility to environmental ocular stress. The stimulator uses light emitting di...

BACKGROUND Deep brain stimulation is increasingly used in the treatment of advanced Parkinson's disease. While its short-term effectiveness is well documented, there are only few reports on long-term outcomes, and the need to repeatedly reprogram the stimulator is seldom reported. CASE PRESENTATION We present a 74-year-old man with gait impairment, which had been mistaken for worsening of the...
