Men’s engagement in maternal and child health care in the preconception health forum is essential because it allows primary prevention of maternal and infant mortality and morbidity. This review aimed to identify strategies to engage men in preconception health.

This scoping review was conducted from August to September 2022. The database searches included PubMed, EBSCO, and ProQuest from 2012 to 2022, related to men’s involvement in reproductive health, preconception health, family planning, maternity, and infant care; articles written in English; national (Indonesia) and international articles; and appropriate thesis. The searched keywords were man/male role, premarital, preconception, reproductive health, and fertility.

The electronic searches turned to 1969 articles, 16 of which met the inclusion criteria and were selected for study analysis. This review identified three themes: identifying programs that are sensitive to the limitations of men; developing community outreach strategies; and engaging management principles, policy, and legislation.

Efforts to engage men in preconception health can be complicated, but several strategic programs have demonstrated some success. Subsequent programs that require men’s participation in preconception health services must be sensitive to the identified barriers.

In this study, a new oxazoline derivative containing 2-phenyl-2-(pyridine-2-yl) oxazoline-3-yl)ethanol (POE) was synthesized from the solvent-free reaction of diethanolamine with 2-benzoylpyridine under microwave conditions. The POE ligand can coordinate to the metal through the amino and pyridine nitrogen atoms. The complexes [Ni(POE)Cl2(H2O)2] and [Cu(POE)2Br2] were synthesized from the reaction of the POE ligand with nickel chloride hexahydrate and copper bromide tetrahydrate, respectively. These complexes were characterized by elemental analysis, FT-IR, UV-Vis, conductivity, and melting point methods. Elemental analysis of the [Ni(POE)Cl2(H2O)2] and [Cu(POE)2Br2] complexes indicates that the POE to nickel and copper metal ratio is 1:1 and 1:2, respectively. In the FT-IR spectrum of the POE ligand, the stretching vibration of C=O in the starting materials 2-benzoylpyridine and NH2 in diethanolamine are absent, and a new C=N stretching vibration is observed. The vibrational bands of Ni-O, Ni-N, and Ni-Cl in the [Ni(POE)Cl2(H2O)2] complex and Cu-Br and Cu-N in the [Cu(POE)2Br2] complex are observed. The electrical conductivity of the complexes indicates that they are neutral.

Recently, the chelation chemistry of Schiff base lanthanide (III) complexes has been widely considered. This work has concentrated on novel types of binuclear lanthanum complexes derived from two salen ligands including N,N′-bis(3-methoxysalicylaldehyde)-1,2-diaminopropane (H2La) and N,N′-bis(3-methoxysalicylaldehyde)-ethylenediamine (H2Lb). The salen ligands have been formed by the precipitation of ethylenediamine and 1,2-diaminopropane with 3-methoxysalicylaldehyde. Different analytical methods have been used for the characterization of prepared compounds in particular elemental analysis, UV-Vis, FT-IR, 1H-NMR, and 13C-NMR spectroscopy. The bidentate behavior of two salen ligands was suggested based on spectral studies. According to the spectral results, the proposed coordination of two salen ligands and their lanthanum complexes was approved.

In this study, the ligand 2-amino-3-(1-hydrogen-indol-3-yl) propanoic acid (Trp) was used to react with chromium metal ion to prepare complex [Cr (Trp)2(OH)(H2O)].This compound was synthesized for the first time and identified by elemental analysis, FT-IR, UV-Vis, conductivity, and melting point techniques. In the FT-IR spectrum of the complex [Cr (Trp)2(OH)(H2O)], the vibrational bands of the acetate and NH2 groups have shifted to lower energies than the free ligand. In addition, the presence of the Cr-N vibration band at 424 cm-1 is due to the coordination of the ligand to chromium metal. The hexa-coordinated complex of Cr with the octahedral geometric structure including [Cr (Trp)2(OH)(H2O)] is proposed.

This study utilized potassium permanganate and natural polymers starch and gelatin as stabilizing agents to the green fabrication of manganese dioxide nanoparticles MnO2-NPs for photocatalytic degradation of methylene blue. MnO2-NPs were characterized using UV-Vis spectroscopy, FT-IR, and X-ray diffraction spectroscopy, as well as Field Emission Scanning Electron Microscopy (FESEM). XRD confirmed the amorphous nature and purity of the nanoparticles. The photocatalytic activity of MnO2-NPs was examined by the degradation of methylene blue dye under neutral pH. Results showed 95% dye degradation within 45 minutes under repeat cycling, indicating the excellent photocatalytic performance. The green synthesis method and effective photocatalytic activity demonstrate of starch and gelatin-stabilized MnO2-NPs as sustainable photocatalysts for degradation of organic pollutants. The produced potential in the two beds with starch and gelatin was examined.

An eight-membered spiro-alkoxy compound Tris[N-(2-(λ1-oxidanyl(ethyl)-2-(λ2-azanyl) ethan-1-amine] N3P3(OC2H5NC2H5N)3 was synthesized by replacing the chlorine atoms of Hexachlorocyclotriphosphazene (HCCTP) with 2-[(2-aminoethyl)amino]ethanol (AEAE) groups. The structure of Tris[N-(2-(λ1-oxidanyl(ethyl)-2-(λ2-azanyl) ethan-1-amine] (TAEAEAP), was characterized through the utilization of several spectroscopic techniques, such as IR, 1H-NMR, 13C-NMR, 31P-NMR, UV, and fluorescence spectroscopy. In addition, we performed DFT level for predicting vibrational spectra, to obtain structural parameters, including the conformation of the substitutional rings, bond lengths, and bond angles. The theoretical and experimental vibrational spectra were compared to validate the proposed model. Moreover, we investigated the emission spectra of TAEAEAP in the presence and absence of metal cations, such as Pb2+, Cu2+, Ni2+, and Cd2+, in a safe and non-toxic solvent mixture of H2O/MeOH (9:1, v/v). The biocompatibility of TAEAEAP was evaluated through an MTT assay conducted on healthy L929 fibroblast cells. Furthermore, molecular docking studies of TAEAEAP with tumour suppressor (1BD8) and transferase/transferase inhibitor (3NUP) proteins were performed. This study involved an investigation into the synthesis, structural analysis, and antibacterial properties of a purple-coloured complex, bis[tris(2-ethylaminoethyl)amine]copper(II) dinitrate, that was formed from the reaction between copper nitrate and TAEAEAP.

Different graphene oxides (GO) (GO1.5, GO3, GO4.5, and GO6) were synthesized and characterized. Cationic dyes, including Methylene Blue (MB) and Crystal Violet (CV) were used as organic pollutants. The amount of dye adsorbed on the synthesized adsorbents increases by increasing the contaminant concentration. The results indicated that contaminant adsorption capacity is enhanced by enhancing the adsorbent dose and then decreases to some extent. As the adsorbent dose increases, the active sites will be more accessible. The adsorbent particles are agglomerated at values ​​higher than the optimal value of the absorbent. Thus, the amount of dye removal is reduced. The adsorption thermodynamic data presented that the negative ΔG of CV and MB removal by the synthesized adsorbents presented physical and spontaneous adsorption. Also, the positive values of ΔH and ΔS showed the endothermic properties of adsorption and the increase of dye irregularity on the adsorbent surface. The isotherm data indicated that MB and CV removal obeyed the Langmuir isotherm model. It means the adsorption process was carried out in specific homogeneous areas of the adsorbent. The results showed that MB and CV adsorption followed PSO kinetic.

A new oxovanadium (V) complex, 2-[(E)-(O-hydroxyplenyl) methylideneamino]-5-guanidinovalerat (quinoline-8-olatoN,O) vanadium oxide (V), [VO(L)(Hq)], (L=(Z)-2-(2-hydroxybenzylideneamino)-5-guanidinopentanoic acid, Hq=quinolin-8-ol), was synthesized from vanadyl acetylacetonate, 2-hydroxybenzaldehyde, L-Arginine, and quinolin-8-ol in methanol, and characterized by 1H-NMR, 13C-NMR, UV-Vis, FT-IR spectroscopy, cyclic voltammetry, and elemental analysis. Analytical data confirmed the coordination of ligand to vanadium in a 1:1 ratio, forming a stable octahedral complex. Antimicrobial activity of [VO(L)(Hq)] was compared to methoxyoxobis (quinoline-8-olato-k2N,O) vanadium(V), [VO(Hq)2(CH3O)], which has no Schiff base ligand, by testing against Gram-positive, Gram-negative bacteria, and Candida albicans fungus. The [VO(L)(Hq)] exhibited enhanced antibacterial and antifungal properties attributed to the azomethine group of the Schiff base. The Schiff base ligand coordination provides an effective approach for tuning the biological properties of metal complexes. These results highlight [VO(L)(Hq)] as a potential new antimicrobial therapeutic agent.

After the Islamic Revolution, the discourse of resistance in the foreign policy of the Islamic Republic was formed under the general discourse of political-jurisprudential Islam with the central sign of pure Muhammadan Islam and with the recitation of Imam Khomeini. Efficient and realistic reaction against the system of domination and arrogance in order to secure the interests of the country. This discourse, which is defined based on the thought of the Imams of the Revolution and the native construction of the country, shows the correct way of laying in line with the ideals and goals of the Islamic Revolution for decision-making bodies in the field of foreign policy and system agents. The first step to establishing the discourse of resistance correctly and completely is to know precisely the meaning and concept of resistance and to analyze its fundamental components.The main question of the present study is related to what are the conceptual components of Islamic resistance in the thought of Imam Khamenei, the memory of God Almighty. To obtain the answer, using the method of "text-based qualitative content analysis", His Holiness's statements about the concept of "resistance" in accordance with the methodological requirements were examined.Findings show that resistance is a planned, efficient, and intelligent functional set in all cultural, economic, political, and social fields, at an individual, social, and institutional levels, in order to strengthen the existential structure of individuals and strengthen the fabric of society and government to confront the internal enemy. Individuals, including the devil and carnal obsession, on the one hand, and confrontation with the external enemy, and on top of that, the global arrogance front and the arrogance of the world, on the other hand, will lead to worldly and otherworldly happiness and perfection.

The discourse of resistance as one of the major manifestations of the discourse of political-jurisprudential Islam to the central sign of pure Muhammadan Islam with the recitation of Imam Khomeini (RA), was formed in response to how the Islamic system behaves and reacts to the system of domination and Based on that, it has tried to draw the framework of the movement path of the system and its agents in the international space and the system of domination to achieve its goals. Applying the discourse of Islamic resistance in accordance with the local approach and creating an efficient decision-making apparatus in the Islamic government, firstly depends on analyzing the thought of the Supreme Leader and methodically and scientifically explaining this in his views and then providing a precise and tangible strategic-operational coordinates for using Islamic resistance. In this regard, the main question of the present study is what is the strategic-operational coordinates of Islamic resistance in the intellectual system of the Supreme Leader, Ayatollah Khamenei. In order to obtain the answer, using the method of "text-based qualitative content analysis" all the statements of His Majesty after the Islamic Revolution of Iran were examined, the components of RESISTANCE were extracted and examined from his perspective, and based on that, the "strategic-operational model of Islamic resistance in the intellectual system of the Supreme Leader" has been drawn. in this study, in order to explain the pattern of resistance, resistance targets in the two areas of islamic goals and national interests, the operational requirements of resistance is met at the three levels of brokers, enemies and observers, resistance realization policies at the two levels of Inside the front and Outside the front, and finally the tools to implement policies and fulfillment of goals are explained in three

Identification and synthesis of new organic iron chelates with higher efficiency than conventional synthetic chelates seems to be necessary to improve the nutritional status of iron in calcareous soils of Iran. In this study, first the amino acid chelates of tyrosine-iron (Fe-Tyr) acid-hydrolyzed chitosan-iron (Fe-Chi) were synthesized by laboratory methods and then some of their properties were characterized. A greenhouse experiment was designed as a factorial experiment based on completely randomized design with three replications including three types of iron chelate, Fe-Chi, Fe-Tyr and Fe-EDDHA (control) and three methods of soil application, fertigation and foliar application. Bean plants were grown and some growth parameters and total iron content in shoot and root were determined. The activity of root and leaf FCR (Ferric Chelate Reductase) enzymes were measured. The results of experimental and theoretical data showed that the tyrosine and chitosan were complexed with iron metal. The results showed that the highest shoot dry weight was observed in soil application of Fe-Chi and fertigation of Fe-Tyr. Also, fertigation of Fe-Chi increased root dry weight compared to control significantly. The highest content of total iron (10.3 mg pot-1) was observed in soil application of Fe-Chi in bean shoots which showed 36% higher Fe uptake than Fe-EDDHA. There was a significant positive correlation between shoot dry weight with iron and nitrogen content in shoots of bean plants. Investigation of root FCR enzyme activity revealed that soil application of Fe-Chi and fertigation of Fe-Tyr had the highest mean of FCR activity. In the foliar and fertigation application of Fe-Tyr, leaf FCR activity increased to 40 days after the start of the experiment. Soil application of Fe-Chi and foliar of Fe-Tyr during plant growth can improve the nutritional status of iron in bean plant

"Soft power" is an essential keyword in contemporary political science vocabulary and its meaning has a long history, and in the conduct of the infallible Imams, there are often examples of attention and application. In the meantime, Imam al-Riḍā's (as) individual and state conduct is full of cases that show his particular interest in this fateful concept whether in the crown prince period or after. The present article is an attempt to explain the principles, tools, and examples of the application of soft power in Imam Riḍā's (as) conduct, which has tried to illustrate the comprehensiveness of this concept in his words and action. The findings show that monotheism, imamate and justice along the prophecy form the basic principles of Raḍavī's soft power, and taqīyya (reservation), debate and miracle are among the most important tools used by the Imam in the area of enforcing the soft power. Also, based on these principles and tools, and within the framework of the roadmap, the application of the Raḍavī’s soft power to the Imamiyyah Shiites, scholars of other religions, theologians, and the government of Mamūn ‘Abbāsī can be illustrated as illustrative examples for describing the Raḍavī’s soft power system,  and by analyzing them, the supreme position of the use of soft power from the point of view of Imam Riḍā (as) based on historical evidence while using a descriptive-analytical method can be shown; an application that illustrates the extent of Riḍā's (as) soft struggle with the caliphate.

Social gaps and splits have long been the cause of social dilemmas and crises in various societies, and threatened the convergence and social cohesion of those societies. Therefore, the desirable management of these gaps has been consistently targeted by government officials through the adoption of efficient strategies. Meanwhile, the management based on concluding social treaties is one of the most important strategies for managing social gaps, as the administration of the prophet of Islam (PBUH) is a graph of the implementation of this strategy. The present paper will attempt to answer this question that what is the contract-oriented position in managing the internal gaps of prophetic society and how does this kind of management affect the creation of social convergence in the same Islamic society of the Prophet (PBUH)? In this regard, while presenting a conceptual model, it first addresses the social divisions of the prophetic society and then focuses on the interactive strategy benchmarking of the Prophet (PBUH) in managing social divisions. It should be noted that the authors of this paper will use the documentary-library method to collect information and use the descriptive-analytical method to answer the above question.
