Abstract
In this research, the extract of Ephedra intermedia Schrenk & C.A.Mey. was encapsulated using the mini-emulsion polymerization method based on methyl methacrylate polymers with a nanometer size. The encapsulated extract was characterized using different analytical techniques. Furthermore, the loading efficiency and release of the plant extract were examined. FT-IR spectroscopy confirmed the formation of an expectational product. The TEM and SEM imaging showed a spherical morphology for the prepared encapsulated extract. The average size of poly-methyl-methacrylate nanoparticles containing Ephedra extract was found to be approximately 47 nm. The extract loading efficiency and encapsulation efficiency test demonstrated a dose-depending behavior on E. intermedia extract for both analyses, which is highly advantageous for traversing biological barriers. The release assay shows a controlled release for the extract at phosphate buffer solution (PBS). A 38 % release was calculated after 36 hours. The results obtained from the present study reveal that encapsulating the plant extract is a suitable alternative to control and increase their medicinal properties.

Novel biosynthesis of gold nanoparticles for multifunctional applications: Electrochemical detection of hydrazine and treatment of gastric cancer. ENVIRONMENTAL RESEARCH 2023; 238:117081. [PMID: 37683794 DOI: 10.1016/j.envres.2023.117081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 08/30/2023] [Accepted: 09/05/2023] [Indexed: 09/10/2023]
Abstract
In this work, an environmentally friendly strategy was used to synthesize gold nanoparticles (Au NPs) using Olea europaea (olive) fruit. Transmission electron microscopy (TEM), UV-Vis spectroscopy, X-ray diffraction (XRD) and energy-dispersive X-ray (EDX) were used to characterize the physicochemical properties of the synthesized NPs. An Au NPs modified glassy carbon electrode was used to investigate the direct electrochemical oxidation of hydrazine. The suggested hydrazine sensor has good performance, such as a wide linear range (2.5-275 μM), low limit of detection (0.09 μM), notable selectivity and excellent reproducibility (RSD = 2.2%). The in-vitro cytotoxicity of three human cancer cell lines (KATOIII, NCI-N87, and SNU-16) was also explored with various concentrations of Au NPs prepared from olive fruit extract. Bio-synthesized Au NPs were found to have cytotoxic properties against gastric cancer in humans based on MTT assay protocol. The obtained results show that green synthesized Au NPs can be successfully employed in electrochemical sensing and cancer treatment applications.

Photofixation of N 2 to ammonia utilizing Ni@TPP-HPA nanocomposite under visible-light illumination. RSC Adv 2023; 13:31303-31313. [PMID: 37901262 PMCID: PMC10600515 DOI: 10.1039/d3ra03921h] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 10/18/2023] [Indexed: 10/31/2023] Open
Abstract
The production of ammonia as an important raw material in the chemical, agricultural, and food industries has been always a significant concern. However, conventional ammonia production methods require high energy consumption and costs. The photocatalytic rotes use green light sources and cost-effective photocatalysts to obtain ammonia from water under aerobic conditions and preventing production of greenhouse gases in the environment. To produce an effective heterogeneous catalyst, a new tetraphenylporphyrin-heteropolyacid (TPP-HPA) nanohybrid material is synthesized and loaded onto Ni nanoparticles in this work. Then, FE-SEM, EDS, XRD, and FT-IR analyses were applied to characterize the prepared nanohybrid material Ni@TPP-HPA. After that, the new inorganic-organic nanohybrid photocatalyst was introduced as an effective, environmental friendly, and recyclable mediator for N2 photofixation. The results showed that Ni@TPP-HPA is a good photocatalyst for the N2 fixation reaction and can be easily recycled without losing its activity for at least five runs. The Ni@TPP-HPA nanocomposite demonstrated the maximum ammonia generation by 2760 μmol L-1 g-1 under mild conditions when using methanol as a hole scavenger. Additionally, effects of solvent type, temperature, reaction time, irradiation source, solution pH, and other electron scavengers on the rate of NH4+ production were investigated and discussed.

Abstract
CONTEXT The global reactivity and molecular stability of sertraline hydrochloride (SHCl) are predicted for chemical and photo-biological applications. SHCl has a wide indirect HOMO-LUMO gap of about 4.77 eV. The p orbital states of nitrogen and chlorine atoms play the main role in HOMO and LUMO energy levels. Maximum optical transitions are observed at the energy range of 4.96 to 5.64 eV. The main reflectivity occurs at the ultraviolet energy range of 5.51 to 6.16 eV. Obtained high absorption in the ultraviolet region is in good agreement with experiments. It is found that SHCl can be used in new antidepressant drugs. METHODS Optoelectronic properties of SHCl was performed using density functional theory (DFT) calculations as implemented in WIEN2k package. The generalized gradient approximation (GGA) and the Modified Becke and Johnson (mBJ) potential are used for calculation of the exchange-correlation potentials.

Abstract
Herein, the chemical profiles of the essential oils and volatiles obtained from the aerial parts of Mentha pulegium L. (Lamiaceae) are reported respectively using microwave-assisted hydrodistillation (MAHD) and headspace solid phase microextraction (HS-SPME) approaches associated to gas chromatography-mass spectrometric (GC-MS) quantification. Using MAHD-GC-MS and HS-SPME-GC-MS techniques, 30 and 28 constituents were screened in the essential oils and volatiles of M. pulegium L. aerial parts with high prevalence of oxygenated monoterpenes and non-terpene hydrocarbons, respectively. Accordingly, in the characterized chemical profiles, carvone was found to constitute about 56.0% of the oil using the former technique (MAHD), whereas oleic acid (20.1%), carvone (17.7%) along with limonene (16.1%) were found as the major constituent components of the volatile profile using the latter approach (SPME). The two methods might be used in combination to obtain a wider set of information about the chemical composition of one specific plant sample.

Abstract
Tanacetum fisherae Aitch. & Hemsl. is an endemic plant growing wild in some brackish regions of Iran. Since there are not enough reports concerning the quantitative and qualitative analyses of its essential oil, it was decided to characterise the respective water-distilled oils obtained from the flowers and leaves of this medicinal plant. Characterisation of the corresponding essential oil profiles revealed that in both of the analysed oils, oxygenated monoterpenes constituted most of the chemical profiles. In this sense, the most prevailing natural compounds in the flower oils were cis-p-2-menthen-1-ol (11.2%), trans-p-2-menthen-1-ol (10.7%), trans-piperitol (7.8%), 1,8-cineole (6.1%), cis-piperitol (3.8%), α-terpineol (3.7%) and terpinene-4-ol (2.1%), whereas the main constituent components of the leaves oils were, respectively, 1,8-cineole (16.7%), cis-p-2-menthen-1-ol (14.6%), trans-p-2-menthen-1-ol (10.4%), trans-piperitol (12.8%), α-terpineol (5.4%), cis-piperitol (2.9%), borneol (2.7%), and terpinene-4-ol (2.1%). In addition, the second rank of natural compound constituting groups was due to oxygenated sesquiterpenes, as well.

Abstract
Undoubtedly, identification of the chemical composition of organic extracts or secondary metabolites of plant materials and evaluation of their potential bioactivity are among the main objectives of natural products-based investigations. In the present study, we report the chemical composition and antidiabetic activity of Sophora pachycarpa (Family Fabaceae) seeds extract (SPE) for the first time. First, the plant seeds were macerated in ethanol. The extract was subjected to analysis on a gas chromatography-mass spectrometry (GC-MS) system to identify the chemical composition. In vivo assay was run to evaluate the antidiabetic activity of the extract. Forty mice were divided into four groups, namely healthy mice, untreated diabetic mice, diabetic mice treated with metformin and diabetic mice treated with SPE. The antidiabetic activity of SPE was analyzed using three statistical methods, namely analysis of variance, K-means, and principal component analysis. According to GC-MS analysis, alkaloids of sophoridine, oleic acid, linoleic acid, and n-hexadecanoic acid were among the most abundant constituent components of SPE. The extract also exhibited a notable antidiabetic activity and remarkably decreased the levels of alkaline phosphatase (ALP), serum glutamic pyruvic transaminase (SGPT), and serum glutamic oxaloacetic transaminase (SGOT) enzymes. The statistical analyses revealed there are no significant differences between the ability of SPE and metformin in the regulation of fasting blood sugar level and liver enzymes (ALP, SGPT, and SGOT). A quinolizidine alkaloid, namely sophoridine, along with fatty acids, viz oleic, linoleic, and n-hexadecanoic acid, were characterized as the major compounds in S. tachycardia seeds extract. The plant extract was also found as a potent agent to reduce blood glucose and liver enzymes.

Abstract
Linum usitatissimum is a candidate as a remedy to treat prostate problems in some folklore medicines. In this study, we have reported the phenolic and flavonoid constituents, antioxidant activity, and potential of the plant extract against prostate cancer cells. The phenolic and flavonoid compound profile of the extract were established using HPLC analysis. While the total phenolic and flavonoid content (TPC and TFC) were analyzed using classic methods. The antioxidant activity of the extract was also evaluated. MTT assay and flow cytometry technique was used to evaluate antiproliferation activity and induction apoptosis of the plant extract on prostate cancer cells of LNCaP. We also evaluated the gene expression of Bax and caspase-3 using the real-time qPCR assay. HPLC result revealed that L. usitatissimum extract (LUE) was rich in phenolic acids such as gallic, ferulic, and vanillic acid with the amount of 3.56, 2.12, 1.24 μg/g extract respectively. 383.4 mg GAE/g and 47.1 mgRuE/g were calculated for total phenolic and flavonoid content. LUE exhibited radical scavenging activity with IC50 = 19.3 ± 1.1 µg/mL. LUE chelated ferrous ions with IC50 = 121.1 ± 1.3 µg/mL. LUE showed anti-proliferative activity on LNCaP cells with the IC50 values of 8.3, 6.3, and 5.4 μg/mL after 24, 48, and 72 h treatment. LUE also increased cell mortality by inducing apoptosis (15.3-29.8%). The real-time qPCR results exhibited an increase in gene expression of Bax and caspase-3. Our in vitro study demonstrates that L. usitatissimum can be considered as an effective agent to inhibit the growth and invasion the human prostate cancer cells.

Abstract
The aim of the experiment was a green synthesis of cobalt nanoparticles from the aqueous extract of Ziziphora clinopodioides Lam (CoNPs) and assessment of their cytotoxicity, antioxidant, antifungal, antibacterial, and cutaneous wound healing properties. The synthesized CoNPs were characterized using different techniques including UV-Vis., FT-IR spectroscopy, X-ray diffraction (XRD), energy dispersive X-ray spectrometry (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). According to the XRD analysis, 28.19 nm was measured for the crystal size of NPs. TEM and SEM images exhibited a uniform spherical morphology and average diameters of 29.08 nm for the biosynthesized nanoparticles. Agar diffusion tests were done to determine the antibacterial and antifungal characteristics. Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC) were specified by macro-broth dilution assay. CoNPs indicated higher antibacterial and antifungal effects than many standard antibiotics (p ≤ 0.01). Also, CoNPs prevented the growth of all bacteria at 2-4 mg/mL concentrations and removed them at 2-8 mg/mL concentrations (p ≤ 0.01). In the case of antifungal effects of CoNPs, they inhibited the growth of all fungi at 1-4 mg/mL concentrations and destroyed them at 2-16 mg/mL concentrations (p ≤ 0.01). The synthesized CoNPs had great cell viability dose-dependently and indicated this method was nontoxic. DPPH free radical scavenging test was done to assess the antioxidant potentials, which revealed similar antioxidant potentials for CoNPs and butylated hydroxytoluene. In vivo experiment, after creating the cutaneous wound, the rats were randomly divided into six groups: untreated control, treatment with Eucerin basal ointment, treatment with 3% tetracycline ointment, treatment with 0.2% Co(NO3)2 ointment, treatment with 0.2% Z. clinopodioides ointment, and treatment with 0.2% CoNPs ointment. These groups were treated for 10 days. For histopathological and biochemical analysis of the healing trend, a 3 × 3 cm section was prepared from all dermal thicknesses at day 10. Use of CoNPs ointment in the treatment groups substantially raised (p ≤ 0.01) the wound contracture, hydroxyl proline, hexosamine, hexuronic acid, fibrocyte, and fibrocytes/fibroblast rate and remarkably decreased (p ≤ 0.01) the wound area, total cells, neutrophil, and lymphocyte compared to other groups. In conclusion, CoNPs can be used as a medical supplement owing to their non-cytotoxic, antioxidant, antibacterial, antifungal, and cutaneous wound healing effects. Additionally, the novel nanoparticles (Co(NO3)2 and CoNPs) were good inhibitors of the α-glycosidase, and cholinesterase enzymes.

Abstract
OBJECTIVE To report the chemical composition and bioactivity (including antioxidant and antimicrobial activity) of essential oils from the rhizomes, stems, and leaves of Etlingera sayapensis (E. sayapensis) A.D. Poulsen & Ibrahim for the first time. METHODS First, the essential oils were obtained using a Clevenger-type apparatus. Then, the essential oils compositions were identified by chromatography methods including GC-FID and GC-MS. For the next step, DPPH radical scavenging activity (RSA), β-carotene bleaching (BCB), and ferrous ion chelating ability (FIC) were chosen to evaluate the essential oils antioxidant activity. Finally, disc diffusion assay and minimum inhibitory concentration method (MIC) was applied to investigate antimicrobial activity of the rhizomes and leaves oils of E. sayapensis against 18 microorganisms. RESULTS All of the oils contained oxygenated monoterpenes (leaves: 74.18%, stems: 75.60%, and rhizome: 54.61%), The essential oil obtained from leaves contained high amount of carvone (21.38%), cis-carveol (13.49%); The rhizomes oil was rich in linalool formate (25.47%), eugenol (11.84%); and the stems oil was dominated by α-terpineol (39.86%), linalool formate (30.55%). The leaves oil represented the highest ability in all of the antioxidant activity tests. For antimicrobial activity, the rhizome oil presented more active when compared to leaves oil against Bacillus subtilis, Bacillus thuringiensis, Staphylococcus aureus, methicillin resistant Staphylococcus aureus (MRSA), Aeromonas hydrophila, Escherichia coli, Enterobacter aerogenes, Proteus mirabilis, Shigella sonnei, Serratia marcescens, Vibrio parahaemolyticus, Candida albicans, and Candida parapsilosis. CONCLUSIONS The most components of the essential oils belong to oxygenated monoterpenes. Linalool formate, carvone, and α-terpineol are found as the most abundant compounds in the oils of the different parts of E. sayapensis. The rhizomes oil can prevent the growth of wide spectrum microorganisms; however, the oils are not highly potent in antioxidant assays.

Abstract
In four grasspea varieties include ardabil, sharekord, mashhad and zanjan, the effects of different salinity concentrations on seed germination percent, proline concentration, malondialdehyde (MDA), germination index, radicle and hypocotyl length and weight were studied. Result showed that salinity had significant effects on seed germination percentage and germination index. The most and least of germination percentage were observed in 6 and 18 dS m(-1), respectively. Salinity had significantly effect on radicle and hypocotyl length, dry and fresh weight, MDA and proline concentration of seedlings. Salinity had not effect on dry weight of seedling. Increasing salinity reduced radicle and hypocotyl length, dry and fresh weight of seedlings and enhanced proline and malondialdehyde in them. Sharkord cultivar had the most germination percentage at 18 dS m(-1) sodium chloride. Sharkord and ardabil varieties were the most tolerance and sensitive varieties to salinity stress, respectively.

Abstract
In order to study the effect of four Root-Zone Temperatures (RZT) (5, 10, 15 and 25 degrees C) on nodulation and nitrogen percent of four grasspea ecotypes (ardabil, zanjan, mashhad and sharkord), an experiment was conducted in a controlled-environmental chamber in 2005. There were differences (p < 0.01) among ecotypes, RZT and ecotypes *RZT for root length, forage dry matter, root dry matter, nodule dry weight, nodule number, nodule cluster number, nodule cluster diameter, nodule diameter, nodule distribution (root length that has nodule) and plant nitrogen percent. Mashad and ardabil ecotypes produced the most and least nodule number at 25 and 5 degrees C, respectively. The maximum and minimum nodule cluster number were observed in ardabil ecotype under 25 and 5 degrees C RZT, respectively. Root distribution was the most and the least in mashhad and ardabil ecotypes under 25 and 5 degrees C RZT, respectively. Ardabil produced the highest dry nodule weight at 25 degrees C RZT. The least dry nodule weight was belonged to ardabil ecotype under 5 degrees C RZT. Plant nitrogen percent was the highest in ardabile ecotype at 15 degrees C RZT and the lowest in mashhad ecotype under 5 degrees C RZT. This experiment showed that at low RZT (i.e., 5 and 10 degrees C) none of ecotypes had preferred on other ecotypes in point of view measured traits except nodule diameter. Ardabile and mashhad ecotypes were better than other ecotypes at 15 and 25 degrees C RZT respectively for most traits.

Bipolar membrane electroacidification of demineralized skim milk. JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2001; 49:2812-2818.

Abstract
The aim of this study was to evaluate the effect of decreasing the mineral content of skim milk by electrodialysis (ED) prior to electroacidification with bipolar membrane (BMEA) on the performance of the process, the chemical composition, and the physicochemical and functional properties of the isolates produced. ED used to demineralize the skim milk solution was very efficient. However, the electroacidification parameters were influenced by the demineralization level of the skim milk solution: the energy efficiency was decreased with an increase in demineralization, but it was still possible to perform BMEA at a very low conductivity level. Moreover, the isolates produced by BMEA after electrodialysis demineralization at different rates showed similar chemical composition, except on potassium and lactose contents for 75% demineralized isolate. These isolates, except on protein load for 75% demineralization rate, showed similar physicochemical and functional properties, whatever the demineralization rate.

Abstract
Bipolar-memibrane electroacidification (BMEA) technology which uses the property of bipolar membranes to split water and the demineralization action of cation-exchange membranes (CEM), was tested for the production of acid casein. BMEA has numerous advantages in comparison with conventional isoelectric precipitation processes of proteins used in the dairy industry. BMEA uses electricity to generate the desired ionic species to acidify the treated solutions. The process can be precisely controlled, as electro-acidification rate is regulated by the effective current density in the cell. Water dissociation at the bipolar membrane interface is continuous and avoids local excess of acid. In-situ generation of dangerous chemicals (acids and bases) reduces the risks associated with the handling, transportation, use and elimination of these products. The aim of this study was to evaluate the performance of BMEA in different conditions of added ionic strength (p(added) = 0, 0.25, 0.5 and 1.0 M) and added salt (CaCl2, NaCl and KCl). The combination of KCl and p(added) = 0.5 M gave the best results with a 45% decrease in energy consumption. The increased energy efficiency was the result of a decrease in the anode/cathode voltage difference. This was due to an increase of conductivity, produced by addition of salt, necessary to compensate for the lack of sufficiently mobile ions in the skim milk. However, the addition of salts, irrespective of type or ionic strength, increased the required operation time. The protein profile of isolates were similar under all experimental conditions, except at 1.0 M-CaCl2.

Abstract
Bipolar membrane electroacidification (BMEA) uses the property of bipolar membranes to split water and the demineralization action of cation-exchange membranes (CEM). As milk mineral salt content is very sensitive to ionic strength and pH changes, the aim of this study was to better understand the effect of changes in mineral content during pH decrease and demineralization of skim milk. The objectives were to investigate the effect of different cationic permselective membranes (CSV and CMX membranes) on skim milk cation migration and protein precipitation during BMEA. The permselectivity of both membranes tested does not influence the final efficiency of BMEA. The purity of the bovine milk casein isolates produced was similar to or higher (97-98% versus 93.4-96.7) than those of commercial isolates, due to a reduced ash content (1.2 versus 2.0-3. 8%) resulting from the CEM demineralizing phenomenon. For both membranes, the main ionic species to migrate was the potassium ions.
