Albumin is the most abundant plasma protein, accounting for approximately 50% of total serum protein in healthy individuals. In recent years, albumin has attracted significant attention due to its biocompatibility, non-toxicity (metabolizing in vivo into harmless degradation products), non-immunogenic properties, ease of purification, and water solubility. These characteristics render it an ideal candidate for a wide range of biomedical applications.

The binding motifs of clusters of Al+ and Al2+ with ethane, Alx+(C2H6)n (x = 1, 2; n = 1-3), are determined using vibrational photodissociation spectroscopy in the C-H stretching region (2550-3100 cm-1) in conjunction with spectra calculated using density functional theory. The relative energies of candidate structures are determined with the B3LYP-D3 and ωB97X-D density functionals and the 6-311++G(d,p) basis set. Local mode Hamiltonian calculations are better able to reproduce the spectra than scaled harmonic calculations, due to contributions from bending overtones and combination bands.

Taurine (TAR) intricately mediates a plethora of physiological processes. This investigation aimed to elucidate the impact of TAR (50, 100, 150, and 200 mg L) seed priming on redox homeostasis, glutathione metabolism, photosynthetic efficiency, osmotic adjustment and nutrient acquisition in pea plants subjected to 100 mm salinity of neutral (NaCl and NaSO) and alkaline (NaCO) salts. Salinity diminished growth, chlorophyll, and photosynthetic efficiency alongside a concurrent rise in reactive oxygen species (ROS), lipid peroxidation, and relative membrane permeability.

Article Synopsis
  • Cadmium (Cd) is toxic to plants and negatively affects their growth and productivity, prompting a study on the potential protective effects of menadiol diacetate (MD) on summer squash.
  • The experiment involved priming squash seeds with different concentrations of MD and assessing their growth, yield, and biochemical responses after exposure to Cd stress, revealing that MD improved certain growth metrics while reducing Cd's harmful effects.
  • The results showed that 10 µM MD enhanced the accumulation of beneficial compounds in the squash and helped sequester Cd in the cell wall, suggesting MD-priming could be a viable method to alleviate Cd toxicity in summer squash plants.
