Hydrobiological study of the small stream on the Czech–Moravian Highlands

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
Zoobenthos of the Fryšávka Rivulet was investigated in the years 2007–2008. Research included also physico-chemical factors of water (temperature, pH, conductivity, oxygen saturation).

T2T Genomes Unveil Centromere Architecture and Adaptive Divergence in Large Yellow Croaker (Larimichthys crocea)

open access: yesAdvanced Science, EarlyView.
This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

On the structure of psychoeducational constructs: taxometric analysis and epistemological implications

open access: yesFrontiers in Psychology
Taxometric analysis (TA) is a technique designed to elucidate the structure of a psychological construct, specifically determining whether the latent variable is categorical (taxon) or dimensional.

Multi‐Habitat Landscape Promotes Microbial Diversity: Insights from the Traditional Agricultural Heritage and the Global Trend

open access: yesAdvanced Science, EarlyView.
The 2500‐year‐old Mulberry‐dyke and Fish‐pond agricultural heritage system reveals how interconnected habitats foster microbial diversity. Multi‐habitat landscapes enhance microbial diversity through cross‐habitat dispersal and adaptive trait convergence. Globally, regions with diverse habitats support a greater diversity of soil microbiomes.

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Taxon- and Site-Specific Melatonin Catabolism

open access: yesMolecules, 2017
Melatonin is catabolized both enzymatically and nonenzymatically. Nonenzymatic processes mediated by free radicals, singlet oxygen, other reactive intermediates such as HOCl and peroxynitrite, or pseudoenzymatic mechanisms are not species- or tissue ...

ggalign: Bridging the Grammar of Graphics and Biological Multilayered Complexity

open access: yesAdvanced Science, EarlyView.
The ggalign package provides a comprehensive framework for composable visualization built on top of ggplot2. Its primary purpose is to enable the construction of complex multi‐plot layouts with consistent observation alignment across plots, particularly for high‐dimensional data contexts such as genomics, transcriptomics, and microbiome studies ...

Phospholipid Remodeling and Tri‐Layer Membrane Reconstruction Mediate Cognitive Effects of Humanized Milk Fat Globules in Neonatal Rats

open access: yesAdvanced Science, EarlyView.
Humanized milk fat globules (MFG) mimic the native composition and structure of human milk, achieved through remodeling of milk fat globule membrane phospholipid composition and reconstruction of the tri‐layer membrane structure. These humanized MFG exhibit improved structural stability and digestibility, and enhance neurodevelopment in formula‐fed rat
