Colony size is linked to paternity frequency and paternity skew in yellowjacket wasps and hornets

BMC Evolutionary Biology, 2014
BackgroundThe puzzle of the selective benefits of multiple mating and multiple paternity in social insects has been a major focus of research in evolutionary biology. We examine paternity in a clade of social insects, the vespine wasps (the yellowjackets

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

How much multiple paternity should we expect? A study of birds and contrast with mammals

Ecology and Evolution
Parentage analyses via molecular markers have revealed multiple paternity within the broods of polytocous species, reshaping our understanding of animal behavior, ecology, and evolution. In a meta‐analysis of multiple paternity in bird and mammal species,

Shadows of doubt: the uneasy incorporation of identification science into legal determination of paternity in Brazil

Cadernos de Saúde Pública
The arrival of DNA paternity testing in the 1980s was met with great enthusiasm in the Brazilian courts. Yet, over the past two decades, Brazilian legal doctrine and jurisprudence have increasingly rejected DNA proof as the sine qua non for paternity ...

Paternity fraud and compensation for misattributed paternity [PDF]

Journal of Medical Ethics, 2007
Claims for reimbursement of child support, the reversal of property settlements and compensation can arise when misattributed paternity is discovered. The ethical justifications for such claims seem to be related to the financial cost of bringing up children, the absence of choice about taking on these expenses, the hard work involved in child rearing,

Microsatellite Evidence for High Frequency of Multiple Paternity in the Marine Gastropod Rapana venosa

PLoS ONE, 2014
Background Inferring of parentage in natural populations is important in understanding the mating systems of a species, which have great effects on its genetic structure and evolution.

Epilepsy Phenotypic Spectrum of NUS1‐Related Disorder: A Case Series

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Epilepsy with myoclonic and atonic seizures (EMAtS), also known as Doose syndrome, accounts for 1%–2% of childhood epilepsies, and various genes have been implicated in causing this epilepsy syndrome. NUS1 encodes for Nogo‐B receptor (NgBR), which stabilizes the dehydrodolichyl‐diphosphate synthase complex in the endoplasmic ...

Temperate-Tropical Variation in Breeding Synchrony and Extra-Pair Paternity Among New World Tachycineta Swallows

Scientific Reports, 2019
Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity of data on closely related species, especially those spanning broad environmental gradients.

A Phase 1, Randomized, Placebo‐Controlled, Multiple‐Dose, Double‐Blind Study to Evaluate and Compare the Pharmacokinetics and Safety of Rimegepant in Healthy Adult Japanese and Caucasian Individuals

Clinical Pharmacology in Drug Development, EarlyView.
Abstract This Phase 1, randomized, placebo‐controlled, double‐blind study assessed the pharmacokinetic profile of rimegepant (25, 75, or 150 mg once daily for 14 days) in healthy Japanese and Caucasian adults. Exposures were modestly increased in Japanese participants compared with Caucasian participants following a single dose of rimegepant (Day 1 ...
