Activities of the chloroplasts and nucleus are coordinated by retrograde signaling, which has crucial roles in plant development and environmental adaptation. However, the connection between chloroplast status and nuclear genome stability is not well understood. Chloroplast state transitions allow the plant to balance the absorption capacity of the photosystems in an environment in which the light quality was changing.

Type 2 diabetes mellitus (T2DM) adversely affects various organs, including the brain and its blood barrier. In addition to the brain, hyperglycemia damages the testes. The testes possess blood-tissue barriers that share common characteristics and proteins with the blood-brain barrier (BBB), including breast cancer-resistant protein (BCRP).

Silver sulfadiazine (SSD) is a widely used antibacterial agent for burn wound treatment owing to its capability in re-epithelialization and wound healing. However, due to its low solubility, the need for an effective drug delivery system is mandatory. This study aimed to optimize SSD nanostructured lipid-based carriers (NLCs), incorporated in a collagen sponge form as an innovative topical dosage form for effective burn wound treatment.

S-adenosylmethionine (SAM)-dependent histamine N-methyltransferase (HNMT) is a crucial enzyme involved in histamine methylation, playing an important role in the epigenetic modification of biology. It entails the addition of methyl groups to histamine molecules, thereby regulating gene expression, cellular signal transduction, and other biological processes. Therefore, gaining a profound understanding of the detailed mechanism underlying HNMT-mediated methylation reactions is instrumental in elucidating the role of histamine methylation in biology.

Aptamers, a kind of short nucleotide sequences with high specificity and affinity with targets, have attracted extensive attention in recent years. Molecular docking method (MDM) is the most common method to explore the binding mode and recognition mechanism of aptamers and small molecules, which generally use the target to dock with the highest scoring tertiary structural model of the aptamer, and the highest scoring result is used as the predicted model. However, this prediction results may miss out the true interaction pattern due to the fact that aptamers are not completely rigid and the natural aptamers conformations are not in a single state.
