Mekhman name origin12/20/2023 For example, HAs from various sources have been used externally for the treatment of hematoma, phlebitis, desmorrhexis, myogelosis, arthrosis, polyarthritis, osteoarthritis, and osteochondrosis. Peat preparations are mainly used as external remedies but can also be used as internal drugs. HAs are employed in oriental medicine, where they continue to be used extensively for treatment of skin diseases, cold stress, rheumatic pain, diabetes, kidney stones, heart ailments, leprosy, and immune system diseases. Humic substances are heterogeneous natural biopolymers that are contained in plant-based substances (peat, brown coal, and benthic sediment) and are represented mostly by humic acids (HAs). The organic matter of peat consists of humic substances (up to 40%), lignin, polysaccharides, lipids, pectins, hemicellulose, and cellulose. Peat is organic soil formed as a result of incomplete disintegration and humification of marsh plants under high humidity conditions. Overall, these data provide a molecular basis to explain at least part of the beneficial therapeutic properties of peat-derived HAs. Furthermore, the HIX was found to be important in determining the number of semiquinone-type free radicals in the HA structures. All HA fractions exhibited antioxidant activity in radical scavenging and electrochemical assays, and their EPR signal had a single line with g = 2.0035, which is consistent with semiquinone type radicals. Moreover, HAp fractions had a significantly higher content of phenolic OH groups (3.6 ± 0.5 mmol/g) versus HAb (3.1 ± 0.5 mmol/g). HAp fractions had a higher content of aromatic structures compared to HAb fractions. Average M r of the fractions ranged from 17.2 to 39.7 kDa, while their humification index (HIX) varied from 0.49 to 1.21. Physical parameters of the HAs were analyzed by UV-Vis, fluorescent, infrared (IR), and electron paramagnetic resonance (EPR) spectroscopy. To address this issue, nine different types of peat, including oligotrophic, mesotrophic, and minerotrophic peat samples, were used for isolation of HA fractions by basic (HAb) and pyrophosphate (HAp) extractions. The village had 27 inhabitants in 2005, and 26 inhabitants in 2015.Although humic acids (HAs) from peat exhibit various therapeutic properties, there is little information available concerning their physicochemical and antioxidant properties. As of 2015, the village has a municipal building, and an aid station. The population is mainly engaged in agriculture and animal husbandry. 'Holy Mother of God') built in 1228, the Panaya Church ( Armenian: Պանայա Եկեղեցի) built in 1249, and a 13th-century khachkar. Historical heritage sites in and around the village include tombs from the 2nd–1st millennia BCE, a 12th/13th-century cemetery, the church of Surb Astvatsatsin ( Armenian: Սուրբ Աստվածածին, lit. As of 2010, only one Greek resident remains in Mehmana. After the war, Artsakh rebuilt six houses in the village. During the First Nagorno-Karabakh War, the village was captured by Azerbaijani forces during the Mardakert and Martuni Offensives, and was almost completely destroyed, with the population fleeing and many moving to Greece. ĭuring the Soviet period, the village was part of the Mardakert District of the Nagorno-Karabakh Autonomous Oblast. From the beginning of the 19th century, Pontic Greeks from present-day Turkey settled in Mehmana, with many coming to mine the ore found in the area. Metal ore has historically been mined in the area of the village, including silver and lead.
