Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

open access: yesFEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Austrelatus zimmermanni (Gschwendtner, 1934) comb. nov. (Coleoptera: Dytiscidae: Copelatinae) with two new subspecies from Japan, and notes on the species biology and ecology

open access: yesEuropean Journal of Taxonomy
Museum specimens and the newly collected material of the species known so far as Copelatus zimmermanni Gschwendtner, 1934 from Japan were examined, and based on our molecular analysis and morphological study, the species is recognised to belong to the ...

Integration of Bayesian molecular clock methods and fossil-based soft bounds reveals early Cenozoic origin of African lacertid lizards [PDF]

open access: yes, 2009
Background Although current molecular clock methods offer greater flexibility in modelling historical evolutionary events, calibration of the clock with dates from the fossil record is still problematic for many groups.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

A New Species of the Genus Takydromus (Squamata: Lacertidae) from Northeastern Guangxi, China

open access: yesAnimals
During our collecting trip to Guangxi in 2016, we collected ten specimens of the genus Takydromus from the suburb of Guilin, northeastern Guangxi, South China, and found that they did not belong to any currently known species. Here, we described this new

Spatiotemporal phylogenetic analysis and molecular characterization of coxsackievirus A4

open access: yesInfection, Genetics and Evolution, 2011
Coxsackievirus A4 outbreaks occurred in Taiwan in 2004 and 2006. The spatiotemporal transmission of this error-prone RNA virus involves a continuous interaction between rapid sequence variation and natural selection. To elucidate the molecular characteristics of CV-A4 and the spatiotemporal dynamic changes in CV-A4 transmission, worldwide sequences of ...

Testing use of mitochondrial COI sequences for the identification and phylogenetic analysis of New Zealand caddisflies (Trichoptera) [PDF]

open access: yes, 2009
We tested the hypothesis that cytochrome c oxidase subunit 1 (COI) sequences would successfully discriminate recognised species of New Zealand caddisflies. We further examined whether phylogenetic analyses, based on the COI locus, could recover currently

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Systematic studies of the South African Campanulaceae sensu stricto with and emphasis on generic delimitations [PDF]

open access: yes, 2009
The South African Campanulaceae sensu stricto, comprising 10 genera, represent the most diverse lineage of the family in the southern hemisphere. In this study two phylogenies are reconstructed using parsimony and Bayesian methods.
