Phosphate elution from anion‐exchange membranes in soil analysis

Agricultural &Environmental Letters, Volume 10, Issue 1, June 2025.
Abstract Resin‐extractable phosphate (PO4‐P) is a widespread sink‐based measure of soil bioavailable phosphorus (P) used in biogeochemistry and soil fertility. However, acid elution of P may hydrolyze organic P and thus compromise measurement of PO4‐P. We evaluated sodium bicarbonate (NaHCO3) as an alternative to sulfuric acid (H2SO4) for PO4‐P elution.

On the Cause and Consequences of Coinfection: A General Mechanistic Framework of Within‐Host Parasite Competition

Ecology Letters, Volume 28, Issue 6, June 2025.
By applying ecological niche theory, our work illustrates the foundational principles for understanding pathogen coinfection via the lens of resource and immune (apparent) competition. Coinfection, that is, within‐host species coexistence, necessitates a competition‐resistance trade‐off and that each parasite primarily affects the niche factor to which

[Dry-distillation of experimental animal wastes containing radioisotopes].

RADIOISOTOPES, 1988
Mice were dry-distilled at 800 degrees C for 10 min, after [32P]orthophosphate or L-[4,5-3H]leucine was intraperitoneally administered. Phosphorus-32 was quantitatively recovered in the residual solid, whereas 95% of 3H was found int he distillate ...

Diurnal Regulation of SOS Pathway and Sodium Excretion Underlying Salinity Tolerance of Vigna marina

Plant, Cell &Environment, Volume 48, Issue 6, Page 3925-3938, June 2025.
ABSTRACT Vigna marina (Barm.) Merr. is adapted to tropical marine beaches and has an outstanding tolerance to salt stress. Given there are growing demands for cultivating crops in saline soil or with saline water, it is important to understand how halophytic species are adapted to the saline environments.

From data to discovery: leveraging big data in plant natural products biosynthesis research

The Plant Journal, Volume 122, Issue 6, June 2025.
SUMMARY Plant natural products or specialized metabolites play a vital role in drug discovery and development, with many clinically important derivatives such as the anticancer drugs topotecan (derived from the natural alkaloid camptothecin) and etoposide (derived from the natural polyphenol podophyllotoxin).

Distribution of phosphorus and calcium from nodal roots of Trifolium repens: the relative importance of transport via xylem or phloem

, 1996
summary The intra-plant distribution of radioactive phosphorus (32P) and calcium (45Ca) exported from a single nodal root of Trifolium repens (white clover) was measured to ascertain if initial allocation of radioisotopes via the xylem was significantly

Demise of the Barra Honda Carbonate Shoal (Costa Rica) at the Paleocene‐Eocene Boundary Linked to Climate Change and Forearc Tectonics

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The latest Cretaceous(?)–Paleocene Barra Honda Formation represents one of the largest carbonate shoals (>900 km2, 350 m thick) of the convergent margin of Costa Rica. Although the mode of formation of the carbonate shoal is well understood, how environmental and tectonic factors interacted to cause its demise near the Paleocene‐Eocene ...

Accuracy of Non‐Invasive Imaging Techniques for the Diagnosis of MASH in Patients With MASLD: A Systematic Review

Liver International, Volume 45, Issue 4, April 2025.
ABSTRACT Background and Aims Metabolic dysfunction‐associated steatotic liver disease (MASLD) is a growing public health problem. The secondary stage in MASLD is steatohepatitis (MASH), the co‐existence of steatosis and inflammation, a leading cause of progression to fibrosis and mortality. MASH resolution alone improves survival.

Technetium ‐ The Unknown Center of the Periodic Table

European Journal of Inorganic Chemistry, Volume 28, Issue 9, March 21, 2025.
It took 78 years from Mendeleev's proposal of an existence of “eka‐manganese” (1869) until it was finally named as technetium in 1947. Another 78 years have passed since then. A good occasion to pinpoint what we know and what we still don't know of this element in the center of the periodic table.
