Lipid and Fatty Acids Accumulation Features of Entomoneis cf. paludosa during Exponential and Stationary Growth Phases in Laboratory Culture

open access: yesDiversity, 2021
Diatoms are capable of accumulating substantial amounts of triacylglycerides in their cells, which differ in the composition of fatty acids depending on the conditions of cultivation, making them attractive subjects in biotechnology. In the present study,

Strategy for the Removal of Satellite Bacteria from the Cultivated Diatom

open access: yesDiversity, 2020
Multiple ecological and genetic studies of diatom algae require an axenic culture. However, algae-associated bacterial biofilms often form in diatom-produced mucus, both during creation of monoclonal cultures from single cells and during biomass growth ...

On the ultrastructure of hibernoma [PDF]

open access: yesCancer, 1975
An electron-microscopic study of hibernoma and a review of the histogenesis, development, and post-natal structural composition of brown and white adipose tissue are presented. The ultrastructural features of hibernoma include multivacuolated and univacuolated cells containing variable numbers of lipid vacuoles, abundant moderately pleomorphic ...

Sphingolipid biosynthesis modulates plasmodesmal ultrastructure and phloem unloading [PDF]

open access: yesNature Plants, 2019
During phloem unloading, multiple cell-to-cell transport events move organic substances to the root meristem. Although the primary unloading event from the sieve elements to the phloem pole pericycle has been characterized to some extent, little is known

Quantification of Protein Uptake by Endocytosis in Carnivorous Nepenthales

open access: yesPlants, 2023
Carnivorous plants adsorb prey-derived nutrients partly by endocytosis. This study quantifies endocytosis in Drosophyllum lusitanicum, Drosera capensis, Drosera roseana, Dionaea muscipula and Nepenthes × ventrata.

Uterine transcriptome analysis reveals mRNA expression changes associated with the ultrastructure differences of eggshell in young and aged laying hens

open access: yesBMC Genomics, 2020
Background Lower eggshell quality in the late laying period leads to economic loss. It is a major threat to the quality and safety of egg products. Age-related variations in ultrastructure were thought to induce this deterioration.

Novel mesostructured inclusions in the epidermal lining of Artemia franciscana ovisacs show optical activity [PDF]

open access: yesPeerJ, 2017
Background Biomineralization, e.g., in sea urchins or mollusks, includes the assembly of mesoscopic superstructures from inorganic crystalline components and biopolymers.

Uptake of Radionuclides by Bryophytes in the Chornobyl Exclusion Zone

open access: yesToxics, 2023
The “Chernobyl nuclear disaster” released huge amounts of radionuclides, which are still detectable in plants and sediments today. Bryophytes (mosses) are primitive land plants lacking roots and protective cuticles and therefore readily accumulate ...

Seed variability of Sisymbrium polymorphum (Murray) Roth (Brassicaceae) across the Central Palaearctic [PDF]

open access: yesPhytoKeys, 2022
This study presents the results of investigation of the micromorphology and variability of Sisymbrium polymorphum seeds collected in 49 localities in the core range and isolated populations of Central Europe, Eastern Europe and Central Asia. In addition,

Aliskiren Reduces the Adrenal Zona Glomerulosa Apoptosis and Autophagy in Wistar Rats with 2K1C Hypertension

open access: yesInternational Journal of Hypertension, 2020
Hypertension is a disease classified as primary or secondary, manifested not only by elevation of blood pressure but also involved in structural and functional changes of target organs. Renal artery stenosis is a leading factor of secondary hypertension,
