Thermal Black‐Infused Polyurethane Rigid Foams: Novel Formulations Toward Higher‐Performance and More Sustainable Insulation

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.
Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

Nucleic Acids as Emerging Regulators of Calcium Phosphate Biomineralization

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Calcium phosphate biomineralization has traditionally been considered a protein‐regulated process. This review highlights the emerging role of nucleic acids, which interact with mineral phases through adsorption, coprecipitation, and templating, thereby influencing crystal nucleation and growth.

Starter fertilizer impact on corn seedling emergence and grain yield uniformity

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Increasing grain yield is often associated with a uniform plant stand and crop development. The use of starter fertilizer, especially when corn (Zea mays L.) is planted early, can promote more uniform crop development. This study aimed to (i) investigate the impact of starter fertilizer placement on corn seedling emergence, (ii) assess whether

Polyphosphates interfere with the host immunity in Legionella infection [PDF]

open access: yes
2026Legionnaire’s disease, caused by Legionella bacteria, is uncommon but serious cause of community-acquired pneumonia. Legionella resides within alveolar macrophages of infected hosts, where it releases effector molecules to evade phagocytic clearance.

Comparative Study of Free and Total Fatty Acids of Spreadable Cheeses by Mass Spectrometry Methods

open access: yesChemFoodChem, Volume 2, Issue 3, September 2026.
This study focuses on the determination of FFAs in spreadable cheeses and alternatives using a fast Liquid Chromatography‐High Resolution Mass Spectrometry method. A Gas Chromatography‐Mass Spectrometry method was used to determine the composition (%) of total FAs in the same samples.

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Diadenosine polyphosphates, extracellular function and catabolism

open access: yes, 1999
Diadenosine polyphosphates (ApnA n = 2-6) are natural compounds that play an important role inside the cell, in both the nucleus and at the cytosol. The transport of ApnA to cytoplasmatic storage granules provides both the end of their intracellular ...

Imaging patterns and genetic associations of brain atrophy across distinct symptom stages in Parkinson's disease

open access: yesNeuroprotection, Volume 4, Issue 3, Page 262-274, September 2026.
Early disease stages showed limited cortical atrophy and enrichment of synaptic and calcium signaling pathways, whereas advanced stages demonstrated widespread cortical degeneration associated with immune activation and extracellular matrix remodeling.
