Although frankincense essential oil (FREO) has become increasingly popular in skin care, research on its biological activities in human skin cells is scarce, if not completely absent. In the current study, we explored the biological activities of FREO in pre-inflamed human dermal fibroblasts by analyzing the levels of 17 important protein biomarkers pertinent to inflammation and tissue remodeling. FREO exhibited robust anti-proliferative activity in these skin cells. It also significantly inhibited collagen III, interferon gamma-induced protein 10, and intracellular cell adhesion molecule 1. We also studied its effect in regulating genome-wide gene expression. FREO robustly modulated global gene expression. Furthermore, Ingenuity Pathway Analysis showed that FREO affected many important signaling pathways that are closely related to inflammation, immune response, and tissue remodeling. This study provides the first evidence of the biological activities of FREO in human dermal fibroblasts. Consistent with existing studies in other models, the current study suggests that FREO possesses promising potential to modulate the biological processes of inflammation and tissue remodeling in human skin. Further research into the biological mechanisms of action of FREO and its major active components is recommended.

Hinged Carboxylate in the Artificial Distal Pocket of an Iron Porphyrin Enhances CO Electroreduction at Low Overpotential.

To efficiently capture, activate, and transform small molecules, metalloenzymes have evolved to integrate a well-organized pocket around the active metal center. Within this cavity, second coordination sphere functionalities are precisely positioned to optimize the rate, selectivity, and energy cost of catalytic reactions. Inspired by this strategy, an artificial distal pocket defined by a preorganized 3D strap is introduced on an iron-porphyrin catalyst (sc-Fe) for the CO-to-CO electrocatalytic reduction.

Rice is highly sensitive to cold stress, particularly at the booting stage, which significantly threatens rice production. In this study, we cloned a gene, CTB6, encoding a lipid transfer protein involved in cold tolerance at the booting stage in rice, based on our previous fine-mapped quantitative trait locus (QTL) qCTB10-2. CTB6 is mainly expressed in the tapetum and young microspores of the anther.

Gastrointestinal infections present major challenges to ruminant livestock systems, and gut health is a key constraint on fitness, welfare, and productivity. Fecal biomarkers present opportunities to monitor animal health without using invasive methods, and with greater resolution compared to observational metrics. Here we developed enzyme-linked immunosorbent assays for three potential fecal biomarkers of gut health in domestic ruminants: two immunological (total immunoglobulin [Ig]A and total IgG) and one inflammatory (lactoferrin).

Background: Fermentation of dietary fiber by the gut microbiota leads to the production of metabolites called short-chain fatty acids, which lower blood pressure and exert cardioprotective effects. Short-chain fatty acids activate host signaling responses via the functionally redundant receptors GPR41 and GPR43, which are highly expressed by immune cells. Whether and how these receptors protect against hypertension or mediate the cardioprotective effects of dietary fiber remains unknown.

Aim: This research concerns the patentability of carvacrol; it could be helpful for researchers to easily identify any innovation in the biotechnological application of this monoterpene as well as other similar compounds.
Background: Like thyme or oregano, several plants in the Lamiaceae family produce carvacrol. It is one of the secondary metabolites with several biological activities, including the improvement in plants' resistance and their protection.
