Hexane extracts of Heracleum verticillatum, H. sibiricum, H. angustisectum, and H. ternatum were studied for their furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. Quantification of the furanocoumarins was performed by H-NMR. Pimpinellin was found to be the main component in the roots of all studied species. Bergapten and imperatorin were the major compounds in the fruits of H. sibiricum and H. verticillatum, respectively, while byakangelicol dominated in H. angustisectum and H. ternatum fruits. The leaf and fruit extracts of H. angustisectum demonstrated the highest DPPH radical scavenging activity and TEAC (IC 0.58 mg/mL and 1.83 mm, respectively). The root extracts of H. verticillatum and H. angustisectum were found to be the most effective against acetylcholinesterase (IC 0.30 and 0.34 mg/mL, respectively). The studied extracts were not active or demonstrated a weak inhibitory effect (%Inh. up to 29.7) towards α-amylase.

The dried root of Peucedanum praeruptorum is often used medicinally and has high pyran- and furanocoumarin content. Although exogenous melatonin (MT) impacts the regulation of plant growth, stress responses, secondary metabolism, etc., it remains unclear whether MT regulates the vegetative growth and development of P.

Background: Human Platelet Lysate (hPL) is a platelet-derived and growth factor-rich supplement for cell culture. It can be prepared from surplus platelet concentrates initially intended for transfusion. Amotosalen-based photochemical pathogen inactivation of platelet concentrates is used in a number of blood establishments worldwide to minimize the risk of pathogen transmission from donor to patient.

Purpose: Melanin's pivotal role in skin protection and its overproduction leading to hyperpigmentation disorders highlight the necessity of regulating melanogenesis, with autophagy identified as a key degradation pathway. Imperatorin, a compound from Angelica dahurica, has been revealed to reduce melanin in epidermal keratinocytes, with the specific effects and mechanisms unknown. The purpose of this study was to investigate the mechanism by which imperatorin, reduces melanin production in HaCaT cells, with a focus on its potential role in promoting autophagy and regulating the PI3K/Akt signaling pathway.

Objectives: Fast thawing for emergency situations and reduction of plasma wastage.
Background: Evaluation of plasma units, pooled and pathogen reduced (PR) in "maxi-pools" with amotosalen and UVA light, and fast thawing.
Methods/materials: Per replicate, 10 WB-derived leukocyte depleted plasma units were frozen within 24 h at ≤ -25°C and stored for 7 days.
