Characterization of octenyl succinylated potato-starch based films enriched with extracts from various honey-bee products.

The study developed octenyl succinylated (OS) potato starch complexes with ethanolic extracts of honey bee products (HBE) and assess their effects on starch-based films properties. X-ray diffraction and thermogravimetric analysis showed that OS starch films had lower crystallinity and higher thermal stability than native ones. Adding HBE enhanced V-type ordering in OS films.

De-etiolation is Almost Color Blind: The Study of Photosynthesis Awakening under Blue and Red Light.

The synthesis and assembly of functioning photosynthetic complexes in chloroplasts developing from etioplasts during the de-etiolation of angiosperm seedlings are imperative for the plant's autotrophic lifestyle. This study compared the de-etiolation process under monochromatic red or blue light of equal photon flux density during a 24-h illumination period of etiolated Arabidopsis seedlings. The aim was to elucidate the impact of these light wavelengths on the etioplast-to-chloroplast transformation and the initiation of light-dependent photosynthetic reactions.

The photoreactivation of 6 - 4 photoproducts in chloroplast and nuclear DNA depends on the amount of the Arabidopsis UV repair defective 3 protein.

Background: 6 - 4 photoproducts are the second most common UV-induced DNA lesions after cyclobutane pyrimidine dimers. In plants, they are mainly repaired by photolyases in a process called photoreactivation. While pyrimidine dimers can be deleterious, leading to mutagenesis or even cell death, 6 - 4 photoproducts can activate specific signaling pathways.

Fungal aerosol and particulate matter in horse stables in Poland.

Horses stay in different types of stables; especially during the cold season, they stay inside for most of the day. A stable is also a place where many people spend quite a lot of time either as employees who care for and train horses or as equine enthusiasts. Keeping horses in stables causes their constant exposure to high concentrations of particulate matter (PM) and molds in the air inside these facilities.
