To investigate the nature of external noise exclusion, we compared central spatial precuing effects in 16 conditions that varied the amount of external noise, the number of signal stimuli, the number of locations masked by external noise, and the number and style of frames surrounding potential target locations. In the absence of external noise, precuing produced only marginal performance impro...

This paper uses a structural VAR model to quantify the extent of international dependence of several emerging markets in Asia and Latin America. A sizable fraction of macroeconomic fluctuations in emerging markets is attributable to external shocks (in many cases more than 50%). External factors are dichotomized into “U.S. monetary policy” and “everything else” shocks. This further decompositio...

Objective. To examine the effects of clinical hypnosis versus NLP intervention on the success rate of ECV procedures in comparison to a control group. Methods. A prospective off-centre randomised trial of a clinical hypnosis intervention against NLP of women with a singleton breech fetus at or after 37(0/7) (259 days) weeks of gestation and normal amniotic fluid index. All 80 participants heard...

BACKGROUND Existing studies regarding women's experiences surrounding an External Cephalic Version (ECV) report on women who have a persistent breech post ECV and give birth by caesarean section, or on women who had successful ECVs and plan for a vaginal birth. There is a paucity of understanding about the experience of women who attempt an ECV then plan a vaginal breech birth when their baby r...

OBJECTIVES If success rate of external cephalic version (ECV) increases, the rate of primary caesarean sections -declines. The aims of this retrospective cohort study were to evaluate the ECV and to identify factors associated with the success rate of ECV for breech presentation at term. The second aim of this study was to analyse the outcome of labour of all patients with a foetus in breech ne...

Study sample Power calculations were not used to determine the sample size. The study sample consisted of 68 patients (out of 73) with breech presentation and a mean (SD) age of 28.6 (3.8) years who agreed to a second attempt at external cephalic version under epidural anaesthesia. (Initially 169 patients out of 171 (3.1% of 5453 births) with breech presentation agreed to undergo an attempt at ...

The human mitochondrial genome is replicated by DNA polymerase γ, which is encoded by polymerase γ gene (POLG1) on chromosome 15q25. Patients with POLG1 mutations usually present as Alpers' syndrome or progressive external ophthalmoplegia. Our patient was a 48-year old woman with sensory ataxic neuropathy, dysarthria, ophthalmoplegia, and dysphagia. Sequence analysis revealed that she has two h...

AIMS To test the hypothesis that in patients with acquired chronic bilateral ophthalmoplegia, abnormal retinal image slippage during head movements would result in abnormal thresholds for visual perception of motion. METHODS Five patients (two males and three females) with ophthalmoplegia were included in the study. The average age was 44 years (range 30-69 years). The aetiology of ophthalmop...

PURPOSE The Minkwitz theorem, which can be proven to apply to the immediate surface surrounding a line of umbilics, states that astigmatism perpendicular to the line changes twice as quickly as the rate of change of power along the line. Our objective is to test how the Minkwitz theorem applies to the design of progressive addition lenses (PALs). METHOD Our primary investigation of the astigm...
