Magnetic resonance imaging evaluation of incision healing after cesarean sections

The purpose of this study was to examine the healing period of incision scar in myometrial wall and the normal pelvis after cesarean sections by means of MRI. In this study 17 voluntary women were examined after their first delivery with cesarean section in the early postpartum period (first 5 days), and following this, three more times in 3-month intervals. The MRI examinations were performed on a 1.0-T system (Magnetom, Siemens, Erlangen, Germany), and sagittal T1-weighted (550/17 TR/TE) and T2-weighted (2000/80 TR/TE) spin-echo (SE) images of the pelvis were obtained. During follow-up examinations incision scar tissues lost their signals within the first 3 months on both SE sequences, and little alteration was observed in the subsequent tests. Zonal anatomy of the uterus reappeared completely 6 months after cesarean sections. The time for the involution of the uterus was independent of the zonal anatomy recovery, and the maximum involution was inspected within the first 3 months. In conclusion, the maturation time of myometrial scar tissue in uncomplicated cesarean sections, which can be evaluated by the signal alterations in MRI, is approximately 3 months, whereas the complete involution and the recovery of the zonal anatomy need at least 6 months

Induced oxidative stress and decreased expression of inducible heat shock protein 70 (ihsp 70) in patients with colorectal adenocarcinomas

Background: Colorectal cancer is one of the most common carcinomas observed in humans. Recently we have reported that increased oxidative stress is associated with human colorectal cancer. There are few and controversial studies on the clinical relevance of the expression of heat shock protein 70 (HSP 70), a member of the HSP family, in colorectal cancer. In this study, we assayed lipid peroxide levels, glutathione peroxidase (GPx) activity and the expression of inducible heat shock protein 70 (ihsp 70) in 20 paired samples of colorectal tumor and adjacent normal tissues in order to determine the relationship between oxidative stress and ihsp 70 expression. Histopathological results were also considered to estabish the clinical relevance of ihsp 70 in colorectal cancer

Relation between bone mineral content and clinical, hormonal and biochemical parameters in postmenopausal women

We studied factors related to bone mass after a natural or surgical menopause in 73 healthy women attending the menopause clinic of a university hospital. In the natural menopause group we found inverse correlations between bone mineral density (BMD) vs, menopausal duration; BMD vs, body mass index (BMI) and BMI vs. inorganic phosphate (Pi), borderline correlations between weight vs. thyroxin (T4) and weight vs, luteinising hormone (LH) and a positive correlation between androstenedione (D4A) vs. urinary calcium (Uca). In the surgical menopause group we found some negative correlations (BMD vs. menopausal duration, BMI vs. Pi; BMI vs. dehydroepiandrosterone sulphate (DS), weight vs. DS and cortisol vs. Uca) and some positive correlations (BMD vs. free testosterone (fT), BMD vs, calcium (Ca), and BMD vs. Uca). We concluded that the serum hormone levels we measured were not useful markers of current bone mineral status

Two remarkable moss species new to Turkey and South-west Asia

Bryum blindii and Dicranella crispa are reported new to Turkey and South-west Asia following a recent bryological excursion to the Ardahan and Burdur regions of Turkey. Illustrations, geographic distribution and comparisons with morphologically similar taxa are given
