Article Synopsis
  • The study explored the use of orange peels to create porous activated carbons through chemical activation, which were then tested as metal catalyst supports for limonene oxidation.
  • Characterization of the materials included analytic techniques such as N2 sorption, XRD, FTIR, SEM, XPS, and XRF to evaluate their properties and elemental composition.
  • Results indicated that modifying activated carbon with cobalt and molybdenum significantly enhanced catalytic activity, with the molybdenum-based catalyst achieving a selectivity of 37% for limonene oxide at a conversion rate of 58%.

α-Pinene is the bicyclic, unsaturated terpene hydrocarbon present in many plants. Due to its beneficial chemical properties, this compound is of great interest and has found numerous applications as a raw material in many chemical industries as well as in medicine and cosmetics. The aim of this study was to evaluate the antioxidant activities of ethanolic extracts obtained from plants containing α-pinene and to test the properties of cosmetic emulsions prepared with these extracts.

Vitamin D helps to balance the levels of calcium and phosphorus to maintain proper bone structure. It is also involved in essential biological roles and displays a wide spectrum of potential benefits in the human body. Since there are many types of fractures that occur at specific ages and due to different circumstances, the influence of vitamin D on the frequency of a particular fracture may differ.

The lesions of medial habenular nuclei increased the pain sensitivity, enhanced the analgesic activity of morphine and slightly activated the behavior. The lesion of fasciculus retroflexus, a pathway connecting habenular nuclei with interpeduncular nucleus enhanced the pain sensitivity less markedly, did not change the efficacy of morphine analgesia, but significantly increased the activity of animals. The lesion of interpeduncular nucleus influenced the pain sensitivity to a smallest degree, did not change the analgesic activity of morphine, but dramatically increased the activity of animals.
