OBJECTIVE. Mixed-density convexity subdural hematoma and interhemispheric suggest nonaccidental head injury. The purpose of this retrospective observational study is to investigate on noncontrast computed tomography in infants with injury compare these findings accidental trauma for whom the date was known. PATIENTS AND METHODS. Two blinded, independent observers retrospectively reviewed scans performed day presentation 9 infant victims (mean age: 6.8 months; range: 1–25 months) 38 4.8...
The brain of hypoxia-tolerant vertebrates is known to survive extreme limitations oxygen in part because very low rates energy production and utilization. To assess if similar adaptations may be involved humans during hypoxia adaptation over generational time, volunteer Quechua natives, indigenous the high Andes between about 3,700 4,900 m altitude, served as subjects positron emission tomographic measurements regional glucose metabolic rates. Two states were analyzed: (a) presumed normal...
The calling song of male crickets, including Oecanthus nigricornis (Walker), attracts females for mating and provides a model system sexual communication. We give the first conclusive identification feature cricket that is both attractive to indicates phenotypic (body size) determines success female reproductive benefits. do this by testing correlations between characteristics aspects phenotype are hypothesized indicate quality. show reliable indicator size age, large associated with...

Objective.—To determine the beneficial use of divalproex sodium as a prophylactic treatment for migraine in children. Background.—Previous studies adults have shown greater than 50% reduction attack frequencies. Few data exist, however, regarding efficacy and safety children with migraine. Methods.—We studied incidence headache relief our patients aged 16 years younger treated prophylactically at institution from July 1996 to December 1998 medication dosage used, concomitant medications,...
The metabolism of glucose in mammalian heart is 25-50% more O2 efficient than the free fatty acids. To assess role substrate preference adaptations to chronic hypoxia, positron emission tomographic measurements regional uptake rates after an overnight fast were made volunteer Quechua subjects and Sherpa subjects, both indigenous altitudes over 3,000 m, a group lowlander volunteers. Highest found Quechuas on arrival Sherpas 3-wk period at low altitude, intermediate altitude lowlanders, lowest...
Abstract Using a sample consisting of firms from 20 countries, we investigate whether conditional conservatism affects the value relevance accounting earnings. We find that association with earnings depends on country-specific level accrual intensity. That is, in countries higher intensity, is positively associated this effect incremental to shareholder protection documented Hung (Journal Accounting and Economics, 30, pp. 401–420, 2001). The results are consistent serving as an efficient...
The relatively small number of ova produced by a female can be fertilized single ejaculate in most species. Why females many species mate with multiple males is therefore enigmatic, especially given that costs associated remating have been well documented. Recently, it has argued may remate at maladaptive rate as an outcome sexually antagonistic coevolution: the evolutionary tug–of–war between manipulation one sex and resistance to being manipulated other sex. We tested this hypothesis...
<b><i>Objective:</i></b> To evaluate the visible and quantitative anatomic distribution of fluorine-18–labeled l-DOPA in healthy human brain, to thereby expand understanding extrastriatal sites levodopa function, provide a broader foundation for clinical research studies fluoroDOPA accumulation patients. <b><i>Methods:</i></b> The authors performed dynamic three-dimensional PET imaging 10 volunteers analyzed images visually quantitatively. Twenty-eight regions interest were applied...
Abstract Motivational asymmetry caused by differences in subjective resource value is a key component of strategic models aggression. We study the role motivational determining differential aggression and mating success male house crickets, Acheta domesticus . also assess extent to which associated with are due direct male–male fighting vs. male–female interactions. manipulated motivation compete for opportunity providing males either no access or nightly females 4 d prior experiment. As...
ABSTRACT Members of the genus Brucella are known worldwide as pathogens wildlife and livestock most common organisms zoonotic infection in humans. In general, brucellae exhibit a range host specificity animals that has led to identification at least seven species. The genomes various species highly conserved, which makes differentiation challenging. However, we found single-nucleotide polymorphisms (SNPs) housekeeping other genes differentiated main or clades thus enabled us develop...
Split-sex-ratio theory assumes that conflict over whether to produce predominately males or female reproductives (gynes) is won by the workers in haplodiploid insect societies and outcome determined colony kin structure. Tests of have potential provide support for kin-selection evidence social conflict. We use natural variation kinship among polygynous (multiple-queen) colonies ant Formica exsecta study associations between sex ratios relatedness versus male brood (relatedness asymmetry)....
Understanding the evolution of polyandry (mating with multiple males) is a major issue in study animal breeding systems. We examined adaptive significance Drosophila melanogaster, species well-documented costs mating which males generally cannot force copulations. found no direct fitness advantages polyandry. Females that mated had greater mean and different variance than females repeatedly same male. Subcomponents reproductive success, including fecundity, egg hatch rate, larval viability,...
