BACKGROUND Mechanically replacing one or more pain generating articulations in the functional spinal unit (FSU) may be a motion preservation alternative to arthrodesis at the affected level. Baseline biomechanical data elucidating the quantity and quality of motion in such arthroplasty constructs is non-existent. PURPOSE The purpose of the study was to quantify the motion-preserving effect of...

The occurrence of a weak auditory warning stimulus increases the speed of the response to a subsequent visual target stimulus that must be identified. This facilitatory effect has been attributed to the temporal expectancy automatically induced by the warning stimulus. It has not been determined whether this results from a modulation of the stimulus identification process, the response selectio...

It is widely accepted that sex steroid hormones play an important and a specific role during the process of sex differentiation in fish. In order to describe the role of the three main sex steroid hormones (testosterone--T, 17beta-estradiol--E2 and 11keto-testosterone--11KT) during embryogenesis and sex differentiation in Eurasian perch, Perca fluviatilis, eggs, larvae and juveniles originating...

The face-sensitive evoked N170 component of the event related potential (ERP) is reduced if another face is presented before when compared to the previous presentation of a low-level control stimulus (phase-scrambled face). This effect is thought to reflect category-specific adaptation processes. Similarly, presenting two faces concurrently also reduces the N170, suggesting that stimuli compete...

Impact of hybridization and irradiation in isolation of superior segregants in four crosses of desi cotton were studied and compared between F2 and F2M2 progenies. The F2M2 progenies of four crosses recorded higher per cent of superior segregants compared to F2 progenies for boll number, boll weight and halo length excepting in KS-16 x MB-3200 cross. Out of four F2M2 progenies, RDC-53 x 9747 cr...

third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (goetz technique). primary healing occurred in all of them without any complication. the conception rate obtained after surgery was 70.1%. five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. three mares have produced several healthy foals without any ...

Accumulated evidence from dozens of cash transfer programmes across the world suggest that there are few interventions that can match the range of impacts and cost-effectiveness of a small, predictable monetary transfer to poor families in developing countries. These results lead many policymakers to consider cash transfer programmes the ‘gold-standard’ in anti-poverty policy with some even adv...

In healthy subjects, dual hemisphere transcranial direct current stimulation (tDCS) over the primary (S1) and secondary somatosensory cortices (S2) has been found to transiently enhance tactile performance. However, the effect of dual hemisphere tDCS on tactile performance in stroke patients with sensory deficits remains unknown. The purpose of this study was to investigate whether dual hemisph...

Genetic influences and endurance exercise have been shown to alter circulating concentrations of dehydroepiandrosterone (DHEA) and its sulfated conjugate, DHEAS. We hypothesized that acute resistance exercise (RE) and training (RET) would increase DHEA steroids, and the magnitude of the increase would be influenced by a steroid sulfatase (STS) gene variation. Fasting blood samples were collecte...

Ribosomal protein S1, the product of the essential rpsA gene, consists of six imperfect repeats of the same motif. Besides playing a critical role in translation initiation on most mRNAs, S1 also specifically autoregulates the translation of its own messenger. ssyF29 is a viable rpsA allele that carries an IS10R insertion within the coding sequence, resulting in a protein lacking the last motif...
