less than 5% of prenatal thymoctes express hla-dr before week 12 of gestation. however, the number of hla-dr- positive cells increases during the late second and third trimesters of development. to determine the role of alpha-smooth muscle actin in fetal thymic hla-dr signaling in different stages of development we examined and compared the immunohistochemical expression of alpha-smooth muscle ...

Background: Although pregnancy is a normal function in women, it is considered as a stressful experience which is associated with many psychological and physical changes in pregnant women. Objectives: This study aims to investigate and compare cognitive function in different trimesters of pregnancy. Materials & Methods: This was a longitudinal cohort study. Participants were 76 pregnantwomen ...

Background & aim: Low levels of maternal haemoglobin and haematocrit in the first, second, and third trimesters are considered as possible risk factors regarding low birth weight (LBW) and preterm labour (PTL). The present study aimed to evaluate the relationship between maternal haemoglobin (Hb) and haematocrit (HCT) levels with LBW and PTL. Methods: This cross-sectional study was conducted on...

The kinematic analysis of gait during pregnancy provides more information about the anatomical changes and contributes to exercise and rehabilitation prescription. The purposes were to quantify the lower limb kinematics of gait and to compare it between the second and third trimesters of pregnancy and with a control group. A three-dimensional analysis was performed in twenty-two pregnant women ...

A prospective study was carried out to determine the relationship between weight gain in the second and third trimesters with the corresponding birth weights in Morogoro, Tanzania. A total of 270 pregnant women who gave birth to singleton deliveries and their consecutive newborns were randomly selected from among women who were attending one antenatal clinic. Average weight gains in second and ...

OBJECTIVE Aims of this study were to determine the IgG and IgM seropositivity to parvovirus B19 during the three trimesters of pregnancy. METHODS Initially, a total of 1,047 pregnant women were included in a prospective study. Blood samples were obtained from 343, 406 and 298 cases in the first, second and third trimesters, respectively. To study the incidence of seroconversion, a second samp...

The study is to measure the serum concentration of ascorbic acid in pregnant women during all the trimesters. Methods: Total serum concentration was measured using the 2,4-Dinitrophenylhydrazine method, which involves the conversion of vitamin C to dehydroascorbic acid in the presence of copper ions and subsequent measurement of the resulting bishydrazone at 540nm. Results revealed that total v...

Background: This study aimed to evaluate the clinical significance of maternal serum creatinine, cystatin C, and uric acid levels in relation fetal death pregnant women with preeclampsia. Methods: retrospective evaluated 708 preeclampsia, 738 healthy were selected as control. Medical records reviewed collect obstetric, neonatal, biochemical data, including concentrations. Results: Maternal conc...
