AI Article Synopsis
- A study was conducted to investigate the pain-relief and anti-inflammatory effects of a plant traditionally used in Ethiopia for headaches, abdominal pain, arthritis, and rheumatism, as previous ethnobotanical claims lacked scientific validation.
- The researchers extracted leaves using 80% methanol and fractionated them into chloroform, ethyl acetate, and water, then tested these extracts for analgesic and anti-inflammatory activities through specific laboratory methods.
- Results showed that all forms of the extract significantly reduced pain and inflammation in various tests, confirming the plant's effectiveness as a traditional remedy for pain and inflammatory issues.
Article Abstract
Background: Ethnobotanical studies in various districts of Ethiopia reported that () is used for the management of headache, abdominal pain, arthritis and rheumatism. However, there is no scientific investigation done so far to confirm these traditional claims. Thus, the aim of this study was to assess the analgesic and anti-inflammatory effects of the 80% methanol extract and fractions of leaves.
Methods: The dried and pulverized leaves of were soaked with 80% methanol to obtain a crude extract. Fractionation was done using chloroform, ethyl acetate and water by a soxhlet apparatus. The analgesic effects of the crude extract and solvent fractions were assessed using acetic acid-induced writhing and hot plate tests whereas anti-inflammatory activities were investigated using carrageenan-induced paw edema and cotton-pellet-induced granuloma models.
Results: In all the tested doses, the 80% methanol extract and solvent fractions revealed substantial (p < 0.001) analgesic activities in acetic acid induced writhing test. In the hot plate method, all the tested doses of crude extract and the solvent fractions produced significant analgesic activities (p < 0.05). In the carrageenan-induced acute inflammation model, all tested doses of the crude extract and solvent fractions resulted in a significant decline in paw edema. The 80% methanol extract and solvent fractions of at all the tested doses significantly reduced inflammatory exudates and granuloma mass formations (p < 0.001).
Conclusion: From the results of this investigation, it can be stated that 80% methanol extract, aqueous, ethyl acetate and chloroform fractions of exhibited considerable analgesic and anti-inflammatory activities, supporting the plant's traditional use as a remedy for a variety of painful and inflammatory conditions.

Crystal structure of bis-{5-(4-chloro-phen-yl)-3-[6-(1-pyrazol-1-yl)pyridin-2-yl]-1-1,2,4-triazol-1-ido}nickel(II) methanol disolvate.

The unit cell of the title compound, [Ni(CHClN)]·2CHOH, consists of a neutral complex and two methanol mol-ecules. In the complex, the two tridentate 2-(3-(4-chloro-phen-yl)-1-1,2,4-triazol-5-yl)-6-(1-pyrazol-1-yl)pyridine ligands coordinate to the central Ni ion through the N atoms of the pyrazole, pyridine and triazole groups, forming a pseudo-octa-hedral coordination sphere. Neighbouring tapered mol-ecules are linked through weak C-H(pz)⋯π(ph) inter-actions into monoperiodic chains, which are further linked through weak C-H⋯N/C inter-actions into diperiodic layers.

Fish visceral waste, which is normally discarded, is considered one of the richest sources of proteinases with potential biotechnological applications. For this reason, alkaline proteinases from viscera of Argentine hake Merluccius hubbsi, Brazilian flathead Percophis brasiliensis, Brazilian codling Urophycis brasiliensis, and stripped weakfish Cynoscion guatucupa were characterized. Individuals were caught by a commercial fleet off the coast of the Argentinean Sea.

To reduce environmental impacts from the shipping industry, the FuelEU Maritime Regulation has set a binding 80 % reduction target for well-to-wake (WTW) greenhouse gas (GHG) emissions by 2050. This article presents a prospective life cycle assessment (LCA) comparing the environmental impacts of e-ammonia, e-methanol, e-Fischer Tropsch (FT) diesel, and e-liquefied natural gas (LNG)-for maritime applications in Europe. In addition to e-fuels, traditional propulsion technologies using very low sulfur fuel oil (VLSFO) and LNG are assessed, both with and without integrating ship-based carbon capture (SBCC) systems.
