Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

British Journal of Pharmacology, Volume 183, Issue 17, Page 5157-5189, September 2026.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

The chemokine receptor‐like fourth extracellular loop of the apelin receptor differentially regulates apelin and elabela binding and signalling

British Journal of Pharmacology, Volume 183, Issue 18, Page 5641-5656, September 2026.
Abstract Background and Purpose Apelin and Elabela are endogenous ligands of the apelin receptor (apelin receptor/APJ), a GPCR involved in cardiovascular regulation and body fluid homeostasis. The human receptor contains a conserved disulfide bridge linking the N‐terminal domain to extracellular loop 3 (ECL3) via Cys19 and Cys281, forming a structural ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, Volume 251, Issue 5, Page 2574-2587, September 2026.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Macroalgae and Bivalve Interactions: A Review of Trophic and Feeding Studies to Assess the Contribution of Macroalgal Detritus to Bivalves

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT There is growing interest in the co‐culture of macroalgae and filter‐feeding bivalves due to anticipated trophic benefits that may enhance the productivity of both organisms. Detritus from cultured macroalgae has the potential to supplement bivalve diets, yet few studies have directly examined this relationship in co‐culture systems.

Natural radioactivity in groundwater – a review

Isotopes in Environmental and Health Studies, 2011
The issue of natural radioactivity in groundwater is reviewed, with emphasis on those radioisotopes which contribute in a significant way to the overall effective dose received by members of the public due to the intake of drinking water originating from groundwater systems.

Natural Radioactivity in Spanish Soils

Health Physics, 1994
The program of studies and surveys of natural radiation and radioactivity in Spain organized by our research group at the end of the 1980s included a 4-y national survey to determine the concentrations of natural radionuclides in soil. Results obtained from measurements of soil samples collected nationwide at > 900 sampling sites are reported and ...

Natural radioactivity in Indian tea

Radiation and Environmental Biophysics, 1985
The paper presents the results of measurements on tea samples collected during 1962 and 1973-1983 period for their natural radioactivity content. The radioisotopes studied under this programme are radium-226, thorium-228, and potassium-40. Tea was found to contain higher concentration of these radionuclides compared to other foodstuffs having ...

Natural Radioactivity

Physics Today, 1952
It may seem astonishing that after radioactive substances have been known for over half a century there should still remain important unsolved problems in the domain of natural radioactivity. This field was the first of the great subdivisions of nuclear physics to be explored, and yet much remains to be done here.

Natural radioactivity in Brazilian groundwater

Journal of Environmental Radioactivity, 2006
More than 220 groundwater samples were analyzed for 228Ra, 226Ra, 222Rn, 210Pb, U(nat), Th(nat), pH, conductivity, fluoride and some additional elements determined by ICP-MS. Since samples from several Brazilian states were taken, involving areas with quite different geologies, no general trend was observed relating the chemical composition and the ...

Natural Radioactivity of Miami Soils

Science, 1960
An important part of man's radioactive environment is the natural radioactivity of soils. This radioactivity varies with soil type and with depth in the soil profile. The relation between gross gamma activity and soil depth for a particular soil (Miami silt loam) is presented, together with a discussion of the contribution of K
