Mild Short‐Term Caloric Restriction Induces Coordinated Changes That Promote Lipid Deposition While Maintaining Thermogenesis Capacity in Interscapular Brown Adipose Tissue of Male Rats

open access: yesThe FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Rats under mild caloric restriction (85% vs. ad libitum) for 2 weeks show metabolic and structural adaptations in iBAT. Caloric restriction increases glycolysis and triglyceride deposition in the tissue, leading to larger lipid droplets. It also reduces mitochondrial iBAT content, while maintaining iBAT thermogenic potential thanks to an increased ...

Recent Progressions in Applications of Bioactive Polysaccharides in Food and Health Sciences: A Comprehensive Review

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Polysaccharides play a pivotal role in the development of safe and healthy foods. They ameliorate fatigue, preserve the microflora of the gastrointestinal tract, and provide health for the gut in living organisms. These biopolymers are applied for the fabrication of breakthrough drug delivery systems and potential platforms in regenerative medicine ...

Unravelling the enigmatic origin of calcitic nanofibres in soils and caves: purely physicochemical or biogenic processes? [PDF]

open access: yes, 2014
Calcitic nanofibres are ubiquitous habits of sec- ondary calcium carbonate (CaCO3 ) accumulations observed in calcareous vadose environments. Despite their widespread occurrence, the origin of these nanofeatures remains enig- matic.

Previously Uncharacterised Aliphatic Amino Acid Positions Modulate the Apparent Catalytic Activity of the EAL Domain of ZMO_1055 and Other Cyclic Di‐GMP‐Specific EAL Phosphodiesterases

open access: yesMicrobial Biotechnology, Volume 19, Issue 2, February 2026.
The A526V substitution, previously not recognised to affect the functionality of the EAL domain, downregulates the apparent catalytic activity of the PAS‐GGDEF‐EAL ZMO1055 phosphodiesterase and other GGDEF‐EAL proteins. Substitution of A526, which is conserved among homologues, with amino acids with longer aliphatic side chains than valine, reverts to ...

Characteristics of the tomato chromoplast revealed by proteomic analysis [PDF]

open access: yes, 2010
Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds.

A structural perspective on α‐glucan catabolism in oxygenic phototrophs

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Starch and glycogen are the main α‐glucan storage polymers in oxygenic photoautotrophs, ensuring metabolic continuity during day/night cycles and environmental stress. Their mobilization requires a suite of catabolic enzymes whose activities are tightly regulated to balance carbon storage with energy demands.

Polysaccharide‐Based Food Packaging Materials: Structural Engineering, Functional Modifications, and Sustainable Applications

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 1, January 2026.
Polysaccharide‐based macromolecules including starch, chitosan, cellulose, pectin, and alginate are engineered into functional packaging films through structural design and targeted chemical modifications. Reinforcement, cross‐linking, and bioactive incorporation enable enhanced mechanical performance, barrier properties, and intelligent responsiveness,

Polysaccharide-synthesizing Glycosyltransferases and Carbohydrate Binding Modules: the case of Starch Synthase III [PDF]

open access: yes, 2013
Glycosyltransferases (GTs) are a ubiquitous group of enzymes that catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds.

Glycogen phosphorylation and Lafora disease [PDF]

open access: yes, 2015
Covalent phosphorylation of glycogen, first described 35 years ago, was put on firm ground through the work of the Whelan laboratory in the 1990s. But glycogen phosphorylation lay fallow until interest was rekindled in the mid 2000s by the finding that ...

Extraction and Comprehensive Characterization of Starch From Ryegrass (Lolium multiflorum L.) Seeds as a Non‐Conventional Source

open access: yesStarch - Stärke, Volume 78, Issue 1, January 2026.
A native starch was extracted from ryegrass (Lolium multiflorum L.), yielding a high‐purity product with a significant starch content. The starch exhibited type A and V crystallinity, with a mean particle size (D50) ~7 nm, high swelling power, and low retrogradation tendency.
