Congenital thrombotic thrombocytopenic purpura (TTP) is a very rare but potentially life-threatening disorder. This phase I/II trial compared the pharmacokinetics and pharmacodynamics safety of three different administration modes anti-von Willebrand factor (VWF) aptamer ARC1779. was prospective clinical with partial cross-over design: periods comprised subcutaneous injections 50 mg ARC1779 on seven subsequent days, low-dose infusion (0.002 mg/kg/min) for 24-72 hours high-dose (0.004-0.006...

Which sex should care for offspring is a fundamental question in evolution. Invertebrates, and insects particular, show some of the most diverse kinds parental all animals, but to date there has been no broad comparative study evolution this group. Here, we test existing hypotheses insect using literature-compiled phylogeny over 2000 species. To address substantial uncertainty phylogeny, use brute force approach based on multiple random resolutions uncertain nodes. The main transitions were...

Western scrub-jays (Aphelocoma californica) cached perishable and nonperishable food items, which they could recover after both short long retention intervals. When items were always degraded at recovery, jays decreased the number of increased their caching relative to a control group whose caches fresh recovery. Jays reduced cached, however, when highly preferred only The findings are discussed in terms role retrospective prospective processes caching.

Insect parental care is extensive and varied, but its life-history implications have never been comparatively tested. Using original literature data, we tested predictions about egg size, number (lifetime fecundity), body size under different modes across a phylogeny of 287 insect species. Life-history theory both comparative intraspecific evidence from ectotherms suggest should select for bigger, fewer eggs, that allometric scaling lifetime fecundity may depend on whether consists...

There is widespread concern regarding the effects of agro-chemical exposure on bee health, which neonicotinoids, systemic insecticides detected in pollen and nectar both crops wildflowers, have been most strongly debated. The majority studies examining effect neonicotinoids bees focussed social species, namely honey bumble bees. However, species are solitary, their life histories differing considerably from these thus it possible that susceptibility to pesticides may be quite different....

1. Which sex should care for offspring depends on the cost and benefits of behaviour each sex. Understanding these differences between sexes is a fundamental step to explain evolution animal societies, but it often difficult quantify them empirically. A possible approach investigate two closely related species that perform very similar type in which caring differs. 2. Using field laboratory data, we estimated costs parental assassin bugs with ecologies: Rhinocoris tristis , has exclusive...

Abstract Most organisms must regulate their nutritional intake in an environment full of complex food choices. While this process is well‐understood for self‐sufficient organisms, dependent offspring, such as bee larvae, practice have limited choices because provided by parents. Nutrient balancing may therefore be achieved parents on offspring's behalf, or both, whether cooperatively conflict. We used the Geometric Framework to investigate capacity larval mason bees Osmia bicornis protein...

While early models of ejaculate allocation predicted that both relative testes and size should increase with sperm competition intensity across species, recent predict may actually decrease as increase, owing to the confounding effect potential male mating rate. A study demonstrated volume decreased in relation increased polyandry bushcricket but mass was not measured. Here, we recorded testis for 21 while (ampulla) mass, nuptial gift number data were largely obtained from literature. Using...

Abstract Batesian mimics, such as hoverflies, can gain protection by resembling noxious species that predators avoid, bees. Such resemblance be behavioural well morphological. Bees commonly have a preference for blue flowers, whilst flies generally prefer yellow and white. We predicted that, driven selection enhanced mimicry, bee-mimicking hoverflies would switched flower from to blue, follow the choices of their models. gathered internet photographs flower-visiting bees wasps, hoverfly...

Ecological stoichiometry has emerged as a tool for exploring nutrient demand and evolutionary responses to limitation. Previous studies of insects have found predictable variability in stoichiometry, both relation body size trophic mode, at ordinal levels or higher. Our study further examines the ecological lability these traits by comparing effects size, mode (larval adult) larval habitat on within one order (Diptera). The also expands previous work analyzing coarse (detritivore, herbivore,...

Organisms limited by carbon, nitrogen or sulphur can reduce protein production costs transitions to less costly amino acids, reducing expression. These alternative mechanisms of nutrient thrift might respond differently selection, but this possibility remains untested. We hypothesized that relatively invariant sequence composition responds long-term variation in concentrations, whereas dynamic expression profiles vary with predictability. Prolonged scarcity favours proteome-wide reduction....

Desiccation is a particular risk for small animals in arid environments. In response, many organisms "construct niches," favorable microenvironments where they spend part or all of their life cycle. Some maintain such environments offspring via parental care. Insect eggs are often protected from desiccation by parentally derived gels, casings, cocoons, but active protection has never been demonstrated. Most free-living thrips (Thysanoptera) alleviate water loss thigmotaxis (crevice seeking)....
