Article Synopsis
- - Tetragonia tetragonioides, a salt-tolerant plant from New Zealand, is studied for its carbonic anhydrase (CA) enzyme activity and isoforms found in its leaves, which help regulate carbon levels in plants.
- - Using a method called protonography, five isoforms of CA with different molecular weights were identified, revealing significant enzymatic activity levels and the ability to assess their function separately.
- - The study examined how certain sulfonamide inhibitors and heavy metal ions affect CA activity, finding that silver and mercury ions were particularly potent inhibitors, affecting the plant's leaf protein activity at very low concentrations.
Nanoaquachelates, the nanoparticles with the molecules of water and/or carboxylic acids as ligands, are used in many fields of biotechnology. Ultra-pure nanocarboxylates of microelements are the materials of spatial perspective. In the present work, the effects of copper and selenium nanoaquachelates carboxylated with citric acid on biomass accumulation of the green algae Chlorella vulgaris were examined.

Cells were grown either in photoautotrophic or photoheterotrophic conditions in the presence of 100 mM ethanol (variant Et) or 40 mM glutamate (variant Gt), or their combination (variant EtGt). The exogenous substrates significantly stimulated light-dependent growth of E.

Pea plants were sprayed with an aqueous solution containing NaNO₃(0.2 mM) and Na₂SO₄(0.

It considers the specific features of their histological structure, a differential diagnostic series, and immunohistochemical markers and gives brief information on treatment and prognosis. The paper depicts a clinical case of lymphoepithelioma-like bladder carcinoma in an 80-year-old woman.
