Several genetic studies were carried out among hypertensive patients to assess allelic association at the 1166 position of the 3' untranslated region of angiotensin II type 1 receptor gene. In addition, attempts have also been made to find out whether telomere length attrition is associated with hypertension. The main aim of this study was to examine the association of A1166C polymorphism of angiotensin II type 1 receptor and telomere length with essential hypertension in Egyptian people. Angiotensin II type 1 genotyping and relative telomere length were investigated by PCR in 40 patients of essential hypertension and 15 healthy controls. The homozygous AA1166 allele frequency was 92.8% among the studied subjects. There was no intergroup variation in A allele frequency in normotensive group. The frequency of homozygous A allele was significantly higher in hypertensive than normotensive subjects (97.5 and 80%, respectively) with higher frequencies in male patients. The average telomere length ratio was significantly shorter in hypertensive than in normal subjects (1.08 ± 0.3 and 1.54 ± 0.18, respectively). No correlation was observed between telomere length ratio and body mass index. This study suggests that the homozygous A1166 allele of angiotensin II type 1 and short telomeres may be predisposing factors for essential hypertension in Egyptians and may be involved in the pathogenesis of the disease. Further strategies for treating high-risk patients could result in prevention or delay of end organ damage.
We study the semi-classical interpretation of the x 3 and x 4 moments of twist-3 parton distribution functions (PDFs). While no semi-classical interpretation for the higher moments of gT (x) and e(x) was found, the x 3 moment of the chirally odd spin-dependent twist-3 PDF h 3 L (x) can be related to the longitudinal gradient of the transverse force on transversely polarized quarks in longitudinally polarized nucleons in a DIS experiment. We discuss how this result relates to the torque acting on a quark in the same experiment. This has further implications for comparisons between the Jaffe-Manohar and the Ji decompositions of the nucleon spin.
Levels of STAT1 and⁄or the protein expression of its negative regulators, PIAS1 and SOCS3, may be a good predictor of response to therapy. These could be used as biomarkers that are easily detected by Western blotting or immunostaining during standard histopathological liver biopsy analysis.
Background: Preeclampsia (PE) is a complex illness linked to conception that affects a variety of bodily functions and is usually connected with perinatal morbidity and deaths. Early PE anticipation will reduce this linked morbidity and death by allowing for routine maternal and foetal monitoring and the use of preventative measures. Aim of the work: the goal of this study is to investigate whether the measurement of maternal serum placental growth factor (PlGF) combined with uterine artery Doppler ultrasound, are useful in early predicting PE and to examine the diagnostic accuracy of the Fetal Medicine Foundation (FMF) Algorithm for the early screening and anticipation of the high-risk PE at 11-13 weeks conception in a group of pregnant women. Patients and Methods: one hundred and twenty primigravida women with living, singleton fetus at 11-13 weeks conception without risk factors other than being primigravida attending antenatal care clinic at the Department of Obstetrics and Gynecology at Tanta University Hospitals. All cases were subjected to ; A signed informed written consent, proper history taking, full clinical examination, estimation of body mass index (BMI), blood pressures and determination of mean arterial blood pressure (MAP), ultrasound, Uterine artery doppler ultrasound examination with the determination of the mean Pulsatility index (PI) of the uterine arteries. Maternal serum levels of PlGF were also measured by specific immunoassay (ELISA). The measured values of MAP, mean uterine artery pulsatility index (PI) and PlGF were converted into multiples of the median (MoM). Then the FMF model was used for the determination of patient-specific risk of PE at 11-13 weeks conception in each case. Results:The main results of the present study revealed that; Only 11 of 120 normal pregnant women were categorized as a high PE risk with a percentage of 9.2% and the rest 109 cases were low PE risk with a percentage of 90.8% by application of FMF algorithm. There was a significant difference between the high and low risks regarding the mean uterian UtA-Pi and PIGF levels at 11-13 weeks. Receiver operating characteristic curve (ROC) demonstrate to what extent it can be depended on PlGF, mean UtA-PI and MAP as a predictor for PE denoting the significant diagnostic performance for PIGF and mean uterine artery pulsatility index (PI). The optimal cutoff value of PlGF value using the ROC curve was ≤40 leading to a sensitivity of 90.91%, a specificity of 96.33%, a PPV of 71.4, a NPV of 99.1% and an accuracy of 95.83%. While the optimal cutoff measure of mean uterine artery PI value using the ROC curve was >1.91 leading to a sensitivity of 90.91%, a specificity of 96.33%, PPV of 71.4, NPV of 99.1% and an accuracy of 95.83%. Conclusion:On the basis of these results, it could be concluded that the combined measurement of maternal serum PlGF concentrations and mean PI of the uterine arteries at 11-13 weeks of conception may help to predict the high-risk PE in primigravida when other parameters of PE anticipation are norm...
Background: A cesarean section (CS) is a life-saving surgical procedure when certain complications arise during pregnancy and labor. However, it is a major surgery and is associated with immediate maternal and perinatal risks and may have implications for future pregnancies as well as long-term effects that are still being investigated. This study aims at determining the prevalence of isthmocele (niche) among those who gave birth through Cesarean section, and figure out how many of the women diagnosed with scar niche are symptomatic. Methods: This observational cross-sectional study involved 300 women who gave birth by CS at the latest 6 months and they were recruited from the outpatient clinics of obstetrics and gynecology department, Tanta university hospital. Results: The prevalence of the niche was 21.7%. And the most common shapes of niche documented were the semicircular defects followed by the triangular defects. The majority of cases were symptomatic while only 7.7% were asymptomatic and discovered accidentally by routine ultrasound examination. The most common symptoms documented were abnormal uterine bleeding (AUB), chronic pelvic pain, dysmenorrhea, and secondary infertility. There was a positive significant relationship between the number of CS, the size of the niche, and the severity or frequency of the presenting symptom (P value < 0.01). Conclusion: Cesarean scar niche has a strong statistically significant association with symptoms such as AUB (especially inter-menstrual bleeding), chronic pelvic pain, and dysmenorrhea. In our study, the prevalence of cesarean niche was 21.7% and the common niche shapes documented were the semicircular and triangular niches.
