PURPOSE This study evaluates the extent to which bilingual children produce the same or overlapping responses on tasks assessing semantic skills in each of their languages and whether classification analysis based on monolingual or conceptual scoring can accurately classify the semantic development of typically developing (TD) bilingual children. METHOD In Study 1, 55 TD children (ages 4;0 [y...

It has long been known that the mitochondrial genome normally mutates at a higher rate than the nuclear genome. Direct estimates of mitochondrial mutation rates can be made by sequencing individuals from mutation-accumulation lines, for which the evolutionary timescale is known exactly. Using such an approach, estimates of mutation rates have been made for a small number of species (e.g. Denver...

We select the letters for these pages from the rapid responses posted on bmj.com favouring those received within five days of publication of the article to which they refer. Letters are thus an early selection of rapid responses on a particular topic. Readers should consult the website for the full list of responses and any authors' replies, which usually arrive after our selection. We compare ...

background: infertility is a factor which has been linked to higher prevalence of sexual dysfunctions in women; however, ambiguous results have been reported about the impact of infertility on women’s sexual satisfaction. the purpose of this study was to compare sexual and dyadic functioning in infertile and fertile women. furthermore, the associations between sexual variables and clinical vari...

Objective: to examine day-to-day associations of coitus, sexual interest, partner emotional support, negative mood and positive mood among adolescent women. Methods: Women (ages 14 – 17 at enrollment; N=146) enrolled from one of three adolescent primary care clinics completed up to five 84-day diaries over a 27-month period. The diaries assessed partner interactions, sexual activity, substance ...

Soybean [Glycine max (L.) Merr.] seed phosphorus is stored primarily as phytic acid, a form in which it is unavailable to monogastric mammals and birds. Because of the nutritional and environmental problems caused by phytic acid, development of cultivars with low phytic acid (lpa) mutations has become an important objective in many soybean breeding programs. Information about the inheritance of...
