Addition of intramuscular to vaginal progesterone for luteal phase support in fresh embryo transfer cycles: A cross-sectional study

Background: Luteal phase deficiency is common in assisted reproductive technology and is characterized by inadequate progesterone production. Various studies have shown that administration of progesterone in fresh embryo transfer cycles increases the rate of clinical pregnancy and live birth rate. Progesterone administration has variable types: oral, vaginal, oil-based intramuscular, and subcutaneous. Objective: This study aims to compare the effect of adding intramuscular progesterone to the vaginal progesterone for luteal phase support in the fresh embryo transfer cycle. Materials and Methods: This study reviewed the information related to 355 women who had a fresh embryo transfer between March 2020 and February 2021 at the Yazd Reproductive Sciences Institute, Yazd, Iran. The participants population were divided into 2 groups based on the type of luteal phase support regime: group I (n = 173) received 400 mg vaginal progesterone alone twice a day from the day of ovum pick up; and group II (n = 182) received 50 mg IM of progesterone in addition to vaginal progesterone 400 mg twice a day from the day of ovum pick up. Chemical and clinical pregnancy rates were compared between groups. Results: The basic characteristics of groups were statistically similar. The rates of chemical and clinical pregnancy were higher in the vaginal plus IM progesterone group than in the vaginal progesterone group. Moreover, chemical pregnancy showed a significant difference between the groups (p = 0.011). Conclusion: Our findings demonstrated that the addition of IM progesterone to the vaginal progesterone improves the chemical pregnancy rate in fresh embryo transfer.

A Bi-objective Model for Mineral Supply Chain Network Design Considering Social Responsibility and solving by a Novel Fuzzy Multi-choice Goal Programming method

The main objective of this research is effective planning as well as greener production and distribution of mineral products in supply chain network. Through a case study in cement industry, it considers the design of the mining supply chain network including several factories with a number of production lines and multiple distribution centers. It leaves part of the transportation operation to contractor companies so as to enable the core company to better focus on its products’ quality and also create job opportunities to local people. It employs a multi-period and multi-product mixed integer linear programming model to both maximize the profit of the factory as well as minimize its carbon dioxide gas emissions which are released during cement production and transportation process. Due to the uncertainty of its cost parameters, fuzzy logic has been used for the modeling and solved via a novel fuzzy multi-choice goal programming approach. Sensitivity analysis has also been done on some key parameters. Comparing results of the model with those from the single-objective models, shows that the model has good efficiency and can be used by managers of mining industries such as cement. Although leaving part of the transportation operations to contractor companies increases the number of vehicles used by the contractor companies, its associated decrease in the number of required factory vehicles, improves both objectives of the model. This should be considered by the managers since on top of profit maximization, it can help them build an eco-friendly image. Mining industries generally generate significant amount of pollutions and companies that pay attention to different dimensions of their social responsibilities can remain stable in the competitive market

Transcendent art in the poems of Sadr al-Mutallahin

Poetry is sometimes used in a logical argument sense of the five major arguments, and the meaning behind it is the argument and expression that its common element is imagination. In fact, the distinguishing feature of poetry from other arguments is the poetic nature of the language. Poetry is sometimes used in an artistic sense and can be considered one of the seven arts. The definition of artistic poetry can be understood as a speech that is firstly rhythmic, secondly rhyming, and thirdly imaginative. In this article, poetry is used in the second sense, as poetry in the artistic sense can have a sublime aspect. In fact, poetry in the first sense has an industrial and organic aspect, while poetry in the second sense has an authentic aspect. Mulla Sadra, in addition to writing in prose in rational knowledge, has also expressed many of his sublime philosophical ideas in poetic language. What Sadr al-Muta'allihin has written in poetic form is poetry in the second sense because it has both the three conditions of being rhythmic, rhyming, and imaginative, as well as expressing sublime wisdom in poetic and sublime art language
