This cross-sectional (descriptive-analytical) study was performed in 2020-2021 on 60 pregnant mothers admitted for delivery in Bent Al-Hoda Hospital in Bojnourd during 6 months. 5cc of blood sample was taken from the selected population to measure the level of vitamin D and was assessed in the two groups. Data were analyzed by SPSS software (version 16) and Mann-Whitney test and linear regression. P<0.05 was considered statistically significant.

In the present study, the mean and standard deviation of serum vitamin D3 level in the group of mothers with PPROM was 18.31±9.15 ng/cc, and in mothers with premature rupture of the membranes after 37 weeks was 20.93±8.68 ng/cc. There was no significant difference between the two groups in terms of serum levels of vitamin D3 (P=0.54).

Investors, as one of the main elements of financial markets, have always looked up for a performance evaluation criterion for various companies. One of the most important performance criteria, is stock return. Considering the deployment of capital market, identifying the factors affecting stock return, is of a great significance. Researchers have always been looking for variables with which help the stock return behavior can be explained. Accounting profit is amongst accounting information which is used to predict stock return. The purpose of this research is to investigate the effect of profitability skewness on stock return prediction. In this regard, to explicate the relationship between profitability skewness and future stock return, three perspectives including behavioral explication, growth opportunity and future profitability have been used. To test the hypotheses, a sample of seasonal data from 127 Tehran Stock Exchange listed companies was selected from 2009 to 2017. The method used to test the hypotheses is two-step Fama-Mac Beth regression using the panel data. The results from testing hypotheses show that the skewness of profitability considering three criteria: gross profit, earning per share to price ratio, and net profit, has a significant and negative effect on future stock returns.

The quality of oocyte is often considered as a limiting factor for fertility, especially IVF. Some mitochondrial mutations, particularly the 4977-bp deletion increase with the age. Thus, this mutation can serve as a marker for cell aging, which indicates the reduced quality of the oocytes for fertilization. It has been suggested that this can also be investigated in the blood cells of women with IVF failure.

1-Determination of the frequency of 4977-bp deletion in women with IVF failure, 2-Investigation of the relationship between 4977-bp deletion and the age of patients.

Polymerase chain reaction was used to detect the 4977-bp deletion in blood samples of 52 IVF failure women and 52 women who had at least one healthy child. After polymerase chain reaction with deleted and wild-type primers, the products were examined using agarose gel electrophoresis.

48.07% of women with IVF failure and 34.62% of healthy women had a mitochondrial 4977-bp deletion, with p=0.163 and OR: 1.749. Also, in association with the age of these patients and the frequency of 4977-bp mutation, p and OR were obtained 0.163 and 1.749, respectively and frequency of this mutation was higher in patients over 35 yr old compared to other subgroups (Patients ≥35: 57.69).

According to the findings of this study, there is no a significant relationship between the frequency of mitochondrial 4977-bp mutation and failure in IVF
