This study aimed to estimate the level of adropin for Iraqi patients with cardiac disease and atherosclerosis and the factors affecting its level and its relationship with the studied variables. This study was conducted on 130 adults, including 90 patients suffering from cardiac disease and atherosclerosis, and 40 uninfected adults were considered a control group. Serum levels of adropin and lipid profile (HDL, LDL, and TC) were estimated . The results of the study showed a significant decrease in the level of adropin (p 0.0001) in the following cases: generally in all patients who affected with cardiac disease and atherosclerosis (4.3 ± 1.5 ng ml) compared with healthy subjects (10.2 ± 2.3 ng mL); in obese patients (3.4 ± 0.7 ng mL) compared to non-obese patients (5.2 ± 1.2 ng mL); in patients who also affected with diabetes mellitus type 2 (3.2 ± 0.8 ng mL) and patients who also affected with hypertension (4.1 ± 1.2 ng mL) when compared with patients who do not have other diseases (5.7 ± 1.5 ng mL). A negative significant correlation between serum adropin level and BMI (r=0.493; p=0.0001), LDL (r=-0.628; p=0.0001) level and TC (r=-0.249, p=0.018) level. A positive significant (r=0.395, P=0.0001) appeared correlation of adropin level with HDL level. It was observed that a lower adropin level could play a vital role in cardiac pathophysiology and atherosclerosis. Also, a decrease in the adropin level can be considered a risk factor for these patients.

A total of 120 quadruplicate study sites were divided into two groups of 60, one of which was not sprayed with desiccants (control sites), and the other received desiccant treatment (experimental sites). A week after the beginning of the experiment, seeds from experimental sites had 1.5 times less moisture content than seeds from control sites (p ≤ 0.05). The peak lipase activity of seeds was recorded during the first 50 days of storage. The lipoxygenase activity was found to increase between 50 and 100 days of seed storage. The activity of lipase in seeds increased significantly at 60 °C (p ≤ 0.05), but with the subsequent increase in temperature to 80 and 100 °C, a noticeable reduction was recorded (p ≤ 0.01). For lipoxygenase, a similar decrease in activity reaction was noticed at temperatures of drying agents starting from 80 °C. For other factors, no similar results were recorded. This means that the activity of enzymes, in particular, lipase and lipoxygenase, plays a key role in the physiological processes of soybean seeds during storage, but can be inhibited at temperatures starting from 80 °C. Desiccants application accelerates the maturation of the seed to the necessary moisture content for two weeks. After seven days of treatment with Reglon, the yellowing of beans and leaves in the lower part of soybean plants was noted as the moisture content of leaves and beans decreased almost twice to 35%, while on the control site, these values were 48% (p ≤ 0.05).\u0000","PeriodicalId":45103,"journal":{"name":"Periodico Tche Quimica","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44537715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Schrödinger equation was recently solved for a combination of different potentials using different traditional methodologies. The studies do not consider the effect of a barrier between the potentials. In reality, the barrier between the potentials has an effect on the energy eigenvalues. In the present work, a Kratzer-Mie-type potential, a combination of Kratzer and Mie-type-constant potentials, was proposed as the interacting potential. The solutions of the radial Schrödinger equation was obtained in the presence of the combined potentials by considering a barrier between the potentials. The energy equation and the corresponding wave functions were explicitly calculated. The calculations were performed by using the methodology of supersymmetric quantum mechanics. This method involves the proposition of superpotential function as a solution to its Riccati differential equation. Numerical results were generated for some diatomic molecules using the energy equation and the diatomic model parameters. Some expectation values for the combined potential were calculated using Hellmann Feynman Theorem, and the effect of the barrier on the expectation values were numerically studied. It was observed that when a particle moves from the lower end to a higher end of a barrier, it absorbs energy from the system for some time. This same behavior was also noted when the particle penetrates through a barrier. Thus, its vibration will only depend on the initial energy, which is absorbed. It was equally seen that as the width of the barrier becomes larger than the height, the energy of the system decreases drastically.\u0000","PeriodicalId":45103,"journal":{"name":"Periodico Tche Quimica","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43912449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Somatostatin is an antiproliferative peptide with pro-apoptotic effects that enhance cell death to prevent tumor growth. This study aimed to investigate the association relationship between DNA methylation in SST promotor and colorectal cancer progression. After DNA bisulfite conversion, SST promoter methylation was examined using quantitative methylation‐specific PCR (qMSP) in 71 cases (19 metastasis CRC, 28 early-stage CRC, and 24 healthy controls). Quantitative methylation‐specific PCR (qMSP) is a real-time PCR method used to determine the unmethylated and methylated cytosine residues using a specific set of primers. The percentage of hypermethylation in SST promoter was 17%, 60%, and 79% for healthy controls, early-stage, and metastasis CRC groups. The results showed a significant association between DNA hypermethylation of SST promoter and CRC progression. P-values were 0.0364 for the early-stage group and 0.0138 for the metastasis group. The results also supported that the DNA hypermethylation block the expression of SST, which in turn induce carcinogenesis.

It adapts to live in anaerobic conditions of the women's vagina and causes Trichomoniasis, a non-viral, sexually transmitted disease (STD). This parasite spreads in all regions of the world, and the global prevalence rate of vaginal Trichomoniasis in women is higher than in men. It is considered a neglected disease in Iraq, as there are few studies about this parasite, especially in Maysan province, where researches are near absent. In this study, two hundred and twentysix vaginal swabs were collected from women who visited hospitals, health centers, and medical clinics in some areas of Maysan province (Amara district, Al-Kahla district, Al-Maymouna district, Al-Majar Al-Kabir district) during the period from November 10, 2019 to February 10, 2020. The microscopic examination of vaginal smears showed that the overall infection rate was 75.22% (170/226). AL-Kahla district had the highest rate of infection (96.15%), while the lowest was in the Maimouna district (60.00%). The age group 34-40 years had the highest infection rate (86.95%), while the age group 15 years had the lowest infection rate (37.50%). Married women had a higher infection (80.92%) than unmarried women (40.62%). The infection rate among nonpregnant women was high (81.11%) than with pregnant women (78.57%). This study showed that vaginal pH has a significant role in protecting the women vagina from Trichomoniasis, once the highest rate of infection (96.63%) was recorded in the vagina with a pH 6, while no infection was recorded at pH 4. It can be concluded that Trichomoniasis is widely spread among women of the Maysan communities, and the condition was affected significantly by some demographic factors such as age, occupation, marital status, husband polygamous, vaginal secretions, and itching and pH of the vagina.\u0000","PeriodicalId":45103,"journal":{"name":"Periodico Tche Quimica","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47575526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
