Rapid purification of human lysosomal membranes, characterisation of the detergent resistent microdomains, purification and reconstitution of the vacuolar proton pump (V-ATPase) [PDF]

open access: yes, 2006
The lysosomal membrane is a dynamic environment where specific interactions among proteins and between proteins and lipids occur. These interactions are necessary for the proper functioning of the lysosomal apparatus that allows the passage of molecules ...

Phosphatases in the soil environment [PDF]

open access: yes, 1980
Enzymes play a key role in nutrient cycling in the soil environment. In this work, four phosphatases of the soil environment were investigated. A study of the effect of metal ions and metal ion concentrations on inorganic pyrophosphatase activity in ...

Beer Production With Umbu (Spondias tuberosa) Using Conventional and Nonconventional Yeast

open access: yesJournal of Food Science, Volume 91, Issue 1, January 2026.
ABSTRACT This study evaluated the fermentation performance and bioactive properties of beers produced by Pichia kluyveri L131 and commercial Saccharomyces pastorianus, individually and in coculture, in wort enriched with umbu pulp. Fermentation profiles were assessed over 12 days, focusing on yeast population dynamics, carbohydrate consumption, and ...

Land use and biodiversity effects on P-transformation in soil [PDF]

open access: yes, 2018
Phosphorus (P) is next to nitrogen (N) an essential nutrient for all living organisms. In contrast to N from volatile species are known, P cannot be replenished from the atmosphere.

The Interplay between the Gut and Ketogenic Diets in Health and Disease

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
This review synthesizes current knowledge on the interaction between ketogenic diets and the gut, covering gut physiology, intestinal immunity, and the gut microbiome. It explores innovative methods for tailoring the diet to maximize benefits while reducing side effects. Emphasis is placed on gut‐mediated mechanisms as a critical interface between diet

The GmGDPD family regulates phosphorus efficiency in soybean and enables precision breeding with domestication‐lost alleles

open access: yesThe Plant Genome, Volume 18, Issue 3, September 2025.
Abstract Phosphorus (P) deficiency severely limits soybean productivity, yet the genetic basis of P efficiency remains underexplored. Here, we systematically identified 27 GmGDPD genes in soybean (Glycine max), revealing that family expansion was driven by segmental/tandem duplication events, accompanied by functional diversification through ...

A Hypothesis: Metabolic Contributions to 16p11.2 Deletion Syndrome

open access: yesBioEssays, Volume 47, Issue 3, March 2025.
16p11.2 Deletion syndrome is associated with brain, body, and behavioral symptoms. A majority of 16p11.2 genes relate to metabolism, involving amino acids/proteins, DNA, RNA, catabolism, lipids, and carbohydrates. Additional contributions include changes in cell structure, signaling, development, immune system, nervous system, and localization.
