Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Sex-biased dispersal, kin selection and the evolution of sexual conflict.

open access: yes, 2015
This work was supported by Portuguese funds from Fundação para a Ciência e a Tecnologia through cE3c Unit FCT funding UID/BIA/00329/2013 and through SAMV Post-Doctoral Research Grant (SFRH/BPD/66042/2009), and by a Natural Environment Research Council ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Intra- versus inter-sexual selection in the dimorphic electric organ discharges of the snoutfish Marcusenius altisambesi (Mormyriformes, Teleostei) [PDF]

open access: yes, 2010
Marcusenius pongolensis (South Africa) and M. altisambesi (Upper Zambezi/Okavango) differ in the sex difference of their electric organ discharges (EODs). It is permanent and graded in the former and seasonally dimorphic in the latter.

On the logic of Fisherian sexual selection [PDF]

open access: yesEvolution, 2019
Abstract In Fisher’s model of sexual selection, a female preference for a male trait spreads together with the trait because their genetic bases become correlated. This can be interpreted as a ‘greenbeard’ system: a preference gene, by inducing a female to mate with a trait-bearing male, favors itself because the male is ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Sexual selection and reproductive trade-offs in caring parents

open access: yes, 2022
Successful reproduction depends on individuals both obtaining mates and other reproductive resources, and producing offspring that are capable of surviving to maturity.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Sexual Selection, Space, and Speciation [PDF]

open access: yesEvolution, 1997
A Fisherian model of sexual selection is combined with a diffusion model of mate dispersal to investigate the evolution of assortative mating in a sympatric population. Females mate with one of two types of polygynous males according to a male's display of one of two sex-limited, autosomal traits; these male traits may be associated with differential ...
