Conversion of Shrimp Aquaculture Waste Into Nutritious Floc Using Taro Flour With Varied C/N Ratios: A Sustainable Approach for Aquafeed Production

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Waste management is a critical challenge in the aquaculture industry, particularly in the cultivation of Pacific white shrimp (Penaeus vannamei). This study explores the potential of converting shrimp aquaculture waste into a nutritious floc biomass by incorporating taro flour as a carbon source at varying carbon‐to‐nitrogen (C/N) ratios.

Establishment of a non‐alcoholic fatty liver disease model by high fat diet in adult zebrafish

open access: yesAnimal Models and Experimental Medicine, Volume 7, Issue 6, Page 904-913, December 2024.
The zebrafish NAFLD model was generated by feeding adult male zebrafish with a high‐fat diet combined with egg yolk powder to induce lipid accumulation and histological pathology. Expression of gene transcripts was then analyzed by RNA‐seq. Our assay successfully established a rapid and effective zebrafish model that can mimic the progression of human ...

Centrin diversity and basal body patterning across evolution: new insights from Paramecium

open access: yesBiology Open, 2017
First discovered in unicellular eukaryotes, centrins play crucial roles in basal body duplication and anchoring mechanisms. While the evolutionary status of the founding members of the family, Centrin2/Vfl2 and Centrin3/cdc31 has long been investigated ...

Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella [PDF]

open access: yes, 1979
Asymmetrical bending waves can be obtained by reactivating demembranated sea urchin spermatozoa at high Ca2+ concentrations. Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the ...

Novel Insights into the Development and Function of Cilia Using the Advantages of the Paramecium Cell and Its Many Cilia

open access: yesCells, 2015
Paramecium species, especially P. tetraurelia and caudatum, are model organisms for modern research into the form and function of cilia. In this review, we focus on the ciliary ion channels and other transmembrane proteins that control the beat frequency

Modulation of a sustained calcium current by intracellular pH in horizontal cells of fish retina. [PDF]

open access: yes, 1993
A sustained high voltage-activated (HVA), nifedipine- and cadmium-sensitive calcium current and a sustained calcium action potential (AP) were recorded from horizontal cells isolated from catfish retina.

Physiological Aspects of Genetics [PDF]

open access: yes, 1948
The biological sciences appear to be in the midst of a period of unprecedented progress. An important salient in the advance is the general recognition of the significance of genes in the economy of the organism.

The mitochondrial genome sequence of the ciliate Paramecium caudatum reveals a shift in nucleotide composition and codon usage within the genus Paramecium

open access: yesBMC Genomics, 2011
Background Despite the fact that the organization of the ciliate mitochondrial genome is exceptional, only few ciliate mitochondrial genomes have been sequenced until today. All ciliate mitochondrial genomes are linear.
