Spermidine Mitigates Immune Cell Senescence and Boosts Vaccine Responses in Healthy Older Adults—A Pilot Study

Aging Cell, Volume 25, Issue 6, June 2026.
Can we boost vaccine responses in older adults? In a double‐blind, randomised, placebo‐controlled pilot study (n = 40, > 65 years), spermidine supplementation (6 mg/day, 13 weeks) was safe and significantly improved immune responses following a 3rd SARS‐CoV‐2 vaccine dose.

Ligand‐specific tuning of CLEC10A signalling strength and dendritic cell responses through engagement of different GalNAc‐containing glycan structures

The FEBS Journal, Volume 293, Issue 11, Page 3187-3210, June 2026.
The authors investigated the effects of various glycan ligands for CLEC10A, a lectin receptor expressed on dendritic cells (DCs). Monocyte‐derived DCs were stimulated with glycan‐conjugated dendrimers in combination with the TLR1/2 ligand Pam3CysK4, and responses were investigated at the mRNA and protein level.

Peroxidase/H₂O₂ Catalyzed Oxidative Oligomerization of 1-Aminopyrene

, 2017
A new florescent oligo(aminopyrene) (OAP) was successfully synthesized by enzymatic approach. For this, H2O2 and Horse Radish peroxidase (HRP) were used as catalyst and oxidant, respectively. The structures of monomer and oxidation product were confirmed

Evaluation of physiological and molecular tools to assess ovarian stages in the black tiger prawn (Penaeus monodon)

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Advancing knowledge of the molecular mechanisms governing vitellogenesis and spawning in the black tiger prawn, Penaeus monodon, requires an efficient method for identifying ovarian stages. Several physiological and molecular tools have been employed to define these stages in laboratory studies.

The Lack of a COPII Cargo Receptor Erv14 Impacts Physiological Functions of the Vacuole in Saccharomyces cerevisiae

Traffic, Volume 27, Issue 2, June 2026.
Loss of the cargo receptor Erv14 in Saccharomyces cerevisiae results in sensitivity to calcium, zinc, neutral extracellular pH, and elevated temperature. Furthermore, cells deleted in the ERV14 exhibits vacuolar fragmentation, enlarged lipid droplets, and metabolic alterations. Ruiz Salas, J. L. (2026) https://BioRender.com/b65g523. ABSTRACT Erv14 is a

Detection of IgG, IgA, IgM and IgE Antibodies in Invasive Amoebiasis in Endemic Areas

, 1990
Entamoeba histolytica-specific serum IgG, IgA, IgM and IgE antibodies were assayed in cases of amoebiasis in an endemic area. Patient groups consisted of amoebic liver abscess (n=18), pre-abscess hepatic amoebiasis (n=22) and amoebic colitis (n=30 ...

Novel tungsten carbide nanorods : an intrinsic peroxidase mimetic with high activity and stability in aqueous and organic solvents

, 2013
Tungsten carbide nanorods (WC NRs) are demonstrated for the first time to possess intrinsic peroxidase-like activity towards typical peroxidase substrates, such as 3, 3’, 5, 5’-tetramethylbenzidine (TMB) and o-phenylenediamine (OPD) in the presence of ...
