Polymer-modified concrete and mortars are widely used with different purposes in precast concrete and prestressed concrete structural elements, bridge decks, buildings, and repair requirements because of their significant behavior under different conditions, such as durability against freezing and thawing, ability to absorb impact loads and good mechanical properties compared to ordinary concretes. This study aims to improve some mechanical properties of cement mortar by using styrene–butadiene rubber (SBR) latex, a superplasticizer, and also decreasing the absorption level to lower values by using these two admixtures. The study shows that using 10% SBR by weight of cement increases the compressive strength from 28.6 to 30.8 MPa and decreases the absorption from 2.3 to 1.7% which gives durability for cement mortar. This study also shows the development in strength achieved by using SBR superplasticizer simultaneously, and absorption decreases to only 0.76% for 10% SBR mixes. In comparison, it was 1.75% for mixes with SBR only.

Background The oxidative stress is one of the main reasons for cardiovascular diseases and also one of results of these diseases, its development (like kidney disease). Objective To identify the effect of oxidative stress nitric oxide and reactive oxygen species on cardiovascular diseases. Methods The study involved 56 subjects comparable in age and sex divided into two groups; 28 hypertensives subjects with kidney disease and 28 apparently healthy subjects as control group. The following analysis was done: 4-Hydroxy-2-nonenal (4HNE), Induced nitric oxide synthase (iNOS) and albumin. Results There was a significant increase in (4HNE) between patients' group and control group. iNOS was significantly higher in patients as compared to controls while there were no significant differences found in albumin between patient and control group. There is a positive relationship between oxidation results from hypertension and their developments. There is a positive correlation between BMI and disease. Conclusion Based on this study is important on ideal weight, because obesity considered main factors for heart disease and hardening of the arteries. In addition, the effect of oxidative stress, which leads to high blood pressure and thus chronic kidney disease. [ABSTRACT FROM AUTHOR]

Polycystic ovarian syndrome (PCOS) is the most common and complex endocrine disorder affecting women in the reproductive age. The etiology of this syndrome is not completely known, so there is a developing proof that supports genetic basis, PCOS has a strong familial preference. This study was carried out to investigate the effect of body mass index (BMI) on ovarian hormones in women with PCOS and healthy women. Eighty-three women aged (17-40) years were divided into two groups for testing (BMI less than 25 and more than 25). Hormonal study of Luteinizing hormone (LH), Androgen, Estradiol (E2) was done for each patient, the results of these hormones in patients compared with controls in both BMI groups with E2/T ratio showed a significant increase in patients women compared to controls in (p<0.05), While the results of Follicle stimulating hormone (FSH) and Total Testosterone (TT) showed an increase with not statistically significant. it has been concluded that the increase in BMI doesn't show to have an opposite effect on FSH, Androgen, E2, and TT levels but the result of LH shows a highly significant increase in PCOS groups compared to controls when BMI>25.

In this paper the effect of terrorist operations in three regions of Baghdad, Iraq were studied on serotonin hormones, in 75 Iraqi individual from (AL-karradah and Abo-Gharib) regions as comparison with Al-jadria as (a control). The correlation between sera serotonin and the levels of lead (Pb), cadmium (Cd), mercury (Hg) and bisphenol-A(BPA) have been selected for study, relation of heavy metals, BPA and monoamine neurotransmitter frameworks has been recommended as a potential underline component of action. The serotonin framework has been moderately ignored, along these lines; the objective of this article is to audit the writing on the connection between heavy metals, BPA and the serotonin. Our examination proposes a positive correlation between serotonin and the levels of lead (Pb), cadmium (Cd), mercury (Hg) and BPA. In conclusion, that serotonin levels in the area of (Al-karadah, Abo-Gharib) pollutants areas were high as compared with the control (Al-jadria) as the lowest percentage of pollution. Thus considerable further investigation will be necessary to understand the role of serotonin in the pathogenesis and high levels in the some regions in Iraq such as AL-karradah and Abo-Gharib.

Persistent organic pollutants polychlorinated biphenyls (PCBs) and bisphenol-A (BPA) are widely known of being toxicants. Exposure to a variety of dangerous toxic effects has been attached in all humans .in this paper the effect of terrorist operation on thyroid gland functions in a sample of Iraqi individual (AL-karradah and Abo-Gharib) comparison with Al-jadria rejoin as (control). The correlation between sera thyroid hormones thyroxine T4, triiodothyronine T3, Thyrotropin TSH and the levels of polychlorinated biphenyls (PCBs) and bisphenol-A (BPA) have been measured. 75 volunteers from three Iraqi areas were included in this study . Their ages ranged between (15-65) years. Our examination proposes an inverse relationship between BPA presentation and thyroid hormones. In this manner, increased persistent organic pollutants exposure might be a factor in the causes of hypothyroidism and thyroid gland function. The result of this study showed that the effect of persistent organic pollutants polychlorinated biphenyls (PCBs) and bisphenol-A (BPA) on thyroid hormones, and the effect of military and terrorist operations on the thyroid gland. In the end we concluded that persistent organic pollutants resulting from the explosions and terrorist operations in the area of (Al-karadah, Abo-Gharib) high compared with the control (Al-jadria) as the lowest percentage of pollution, this leads to many diseases on the health of the human body and also the effect of persistent organic pollutants on the thyroid gland and its negative effect on thyroid hormones and cause thyroid disease.

In this paper the effect of terrorist and military operations in three regions of Baghdad, Iraq were studied on thyroid gland function and serotonin hormones, in 75 Iraqi individual from (AL-karradah and Abo-Gharib) regions as comparison with Al-jadria (control). The correlation between sera thyroid hormones thyroxine T4, triiodothyronine T3, thyrotropin TSH and serotonin have been indicated , the utilization of thyroid hormones as a compelling subordinate treatment for full of feeling issue has been contemplated in the course of recent decades and has been adjusted more than once. Communication of the thyroid and monoamine neurotransmitter frameworks has been recommended as a potential underline component of action. The serotonin framework has been moderately ignored, along these lines; the objective of this article is to audit the writing on the connection between thyroid hormones and the mind serotonin. Our examination proposes a negatively relationship between serotonin and thyroid stimulating hormones (TSH), a positive correlation between serotonin and thyroxine , while there were significant positive correlations between serotonin and triiodothyronine. In conclusion, there is powerful confirmation, that the thyroid economy has a balancing sway in the brain serotonin system, thus considerable further investigation will be necessary to understand the role of serotonin in the pathogenesis and high levels in the some regions in Iraq such as AL-karradah and Abo-Gharib.

The heavy metals mercury (Hg), lead (Pb) and cadmium (Cd) are widely known of being toxicants. exposure to a variety of dangerous toxic effects has been attached in all humans.in this paper the effect of terrorist operation on thyroid gland functions in a sample of Iraqi individual (Al-karradah and Abo-Gharib) comparison with Al-jadria rejoin as (control). the correlation between sera thyroid hormones thyroxine T4, triiodothyronine T3, Thyrotropin TSH and Thyroglobulin-Ab (Tg-Ab) and the levels-of lead, cadmium, also mercury have-been measured. 75 volunteers from three Iraqi areas were included in this study . our examination proposes an inverse relationship between Hg presentation and thyroid hormones, a positive correlation between Cd exposure and thyroid hormones , but the associations with Pb was negative. there were significant positive correlations between the heavy metals themselves. In this manner, increased heavy metals exposure might be a factor in the etiology of hypothyroidism diseases and thyroid gland function. the result of this study showed that the effect of heavy metals (blood serum Hg, blood serum Pb, blood serum Cd) on thyroid hormones, and the effect of military and terrorist operations on the thyroid gland. In the end we concluded that the heavy elements resulting from the explosions and terrorist operations in the area of (Al-karadah, Abo-Gharib) high compared with the control (Al-jadria), this leads to many diseases on the health of the human body and also the effect of heavy elements on the thyroid gland and its negative effect on thyroid hormones and cause thyroid disease.
