Their aerial parts have been widely used in traditional medicine. The present study, for the first time, aimed to investigate flavonoid constituents and chromatographic pattern of the methanolic extract of leaf from <em>Marrubium</em> and <em>Ballota</em> species. The technique was performed on High Performance Liquid Chromatography (HPLC)-Micromass Quattro micro Atmospheric Pressure Ionization (API) Mass Spectrometer in six taxa. A total of 59 chemical compounds were recognized, among which 49 flavonoids, three polyphenols, and one methoxyphenol were identified. In addition, five chemical groups were recognized in <em>Marrubium</em> and <em>Ballota</em> species. It is noteworthy that<em> Marrubium</em> and <em>Ballota</em> species provide a major source of apigenin, kaempferol, and quercetin glycosides. The flavonoid compounds, such as licoricidin, sophoraflavanone G, and methyl robustone were highly frequent considering qualitative markers for the genus <em>Marrubium</em>. Despite the striking similarity between <em>Marrubium</em> and <em>Ballota</em> species, they were accurately separated using chemical markers, particularly the mass (MS/MS) spectra of flavonoid compounds, which can develop the functional products and pharmaceutical, chemotaxonomic, and chemo diversity purposes for <em>Marrubium</em> and <em>Ballota</em> genera. https://jsciences.ut.ac.ir/article_85044_be00df501fe7778e4c74d5eacc3ff140.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110432420211201Green Synthesis, Characterization, and Biological Evaluation of Hydroxyl-Capped Tellurium Nanoparticles3213308213610.22059/jsciences.2021.321284.1007641ENRMirjaniBiotechnology Research Center and Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranNSetayeshBiotechnology Research Center and Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranMohammad AliFaramarziBiotechnology Research Center and Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranMSharifzadehDepartment of Pharmacology and Toxicology, Faculty of Pharmacy and Toxicology and Poisoning Research Centre, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranMKhoshayandDepartment of Drug and Food Control, Faculty of Pharmacy and Pharmaceutical Quality Assurance Research Center, Tehran University of Medical Sciences Tehran, Islamic Republic of IranBZareBiotechnology Research Center and Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranOSabzevariDepartment of Pharmacology and Toxicology, Faculty of Pharmacy and Toxicology and Poisoning Research Centre, Tehran University of Medical Sciences, Tehran, IranAhmad RezaShahverdiDepartment of Drug and Food Control, Faculty of Pharmacy and Pharmaceutical Quality Assurance Research Center, Tehran University of Medical Sciences Tehran, Islamic Republic of IranJournal Article20210331In this study, we used a simple green method for preparing tellurium nanoparticles and mainly evaluated their toxicological effects. The nanoparticles were synthesized using lactose and characterized with different instrumentation methods. The <em>in vitro</em> and <em>in vivo</em> cytotoxicity of tellurium nanoparticles and its effect on lipid profile were also evaluated. Hydroxyl-capped tellurium nanoparticles were successfully fabricated by lactose. The results showed spherical tellurium nanoparticles with a mean size of 89 nm. The toxicological study showed that the tellurium nanoparticles did not exhibit any toxicity on the primary cells. The LD<sub>50</sub> values for the nanoparticles were 327 and 295 mg/kg for oral and intraperitoneal administrations, respectively. Also, the results showed a significant reduction in liver enzymes at the 16, 24, and 40 mg/kg doses. Hematological parameters indicated no significant suppressive changes between the animals that were administered tellurium nanoparticles and the control group. In addition, the effects of tellurium nanoparticles on hypercholesterolemic risk factors in mice fed with cholesterol demonstrated the depletion of triglyceride, cholesterol, and low-density lipoprotein. This study showed that the toxicity of tellurium nanoparticles was lower than tellurium ions. Furthermore, tellurium nanoparticles decreased the cholesterol and triglyceride levels in the animal model.https://jsciences.ut.ac.ir/article_82136_d15ab5c8f80f3cb78e4f00ac8490ea3d.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110432420211201Magma Evolution and Mantle Metasomatism: Constraints on Olivine Composition in Potassic-Ultrapotassic Mafic Rocks from Lar Igneous Suite, SE of Iran3313408213710.22059/jsciences.2021.309493.1007564ENSasanGhafaribijarDepartment of Geology, Faculty of Sciences, University of Shahid Bahonar, Kerman, Islamic Republic of IranMohsenArvinDepartment of Geology, Faculty of Sciences, University of Shahid Bahonar, Kerman, Islamic Republic of IranSaraDargahiDepartment of Geology, Faculty of Sciences, University of Shahid Bahonar, Kerman, Islamic Republic of IranJournal Article20200906The Lar igneous suite (LIS), in southeastern Iran, is part of post collisional alkaline magmatism in Sistan suture zone. Shonkinite and kersantite are the only two high-Mg, K-rich olivine bearing rocks in the LIS. We study major and some compatible trace elements in the Lar shonkinite and kersantite (LSK) olivines to define mantle mineralogy and metasomatic processes. Olivines in shonkinite have higher Fo (83-90), compared with those in kersantite (Fo<sub>76-80</sub>). Ca and Ni contents in the olivines are relatively low, whereas their Mn and Ti contents are high and variable, respectively. Low Ni contents exhibit olivine crystallization at igneous conditions from a magma originated by partial melting of an olivine-rich mantle source. Geochemical date reveal that magma evolution is responsible for high-Mn and low Fo contents in kersantitic olivines. In contrast, high Mn, Mn/Fe and Fo contents in shonkinitic olivines indicate an existence of Mn-rich and Ca-Si-poor metasomatic agents in the source. So, considering the Middle Oligocene-Miocene post-collision nature of the Lar igneous suite, melts or fluids derived from upwelling asthenosphere in the form of magnesitic-carbonatite melts, had great potential in metasomatism of subcontinental lithospheric mantle. This CO<sub>2</sub> and K-rich liquid then reacts with peridotite to produce new mineral assemblages including low-Ca clinopyroxene, olivine and phlogopite. Partial melting of such metasomatized source region was responsible for producing the undersaturated, K-rich shonkinite and kersantite in the LIS. https://jsciences.ut.ac.ir/article_82137_4e73f715fca60fa7ea3524c02c58a005.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110432420211201(2n+1)-Weak Module Amenability of Triangular Banach Algebras on Inverse Semigroup Algebras3413478060910.22059/jsciences.2021.295337.1007478ENEbrahimNasrabadiDepartment of Mathematic, Faculty of Mathematic Science and Statistics, University of Birjand,

The maximum likelihood and uniformly minimum variance unbiased estimators of the purposed parameter have been derived for the Exponential distribution. Moreover, the nonparametric estimator of this parameter has also been obtained as well as some important properties of this estimator. A simulation study and the analysis of a real data set have been done for illustrative purposes.https://jsciences.ut.ac.ir/article_85046_011fd662046547ad93343d33cc21095f.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110432420211201Generation of Entanglement in Qutrit Spin Coherent States by Nonlinear Hamiltonian3593658532910.22059/jsciences.2022.325672.1007653ENAzitaNajiDepartment of Physics, Faculty of Science, Shahid Chamran University of Ahvaz, Ahvaz, Islamic Republic of IranN.ShadmanDepartment of Physics, Faculty of Science, Shahid Chamran University of Ahvaz, Ahvaz, Islamic Republic of IranJournal Article20210619We study entanglement in coherent spin states and several superpositions of multi-qutrit coherent states evolved under the one-axis counter-twisting Hamiltonian in the presence and absence of a magnetic field. Considering a non-entangled multi-qutrit spin coherent state as an initial one, it is found that the entanglement is instigated with an oscillatory behavior in time; however, its average is a decreasing function of the magnetic field. Also, we observe that under this Hamiltonian, the two-qutrit superposed state retains its maximum entanglement with no change, while, the negativity for the three-qutrit superposed state oscillates in time and its average increases in the presence of the magnetic field.https://jsciences.ut.ac.ir/article_85329_6a47140ed84247b226c70f96b0bf4988.pdf
