Relationship of transforming growth factor-beta(1) with tumour necrosis factor-alpha and endothelial activation in patients with stable renal transpl…
2008
SUMMARY: Aim: To evaluate whether or not transforming growth factor-beta1 is related to inflammation markers and to intercellular and vascular cell adhesion molecules in patients with stable renal transplantation. Methods: Serum concentrations of transforming growth factor-beta1, tumour necrosis factor-alpha, C-reactive protein and adhesion molecules were analysed in 33 renal transplanted patients, 33 patients with chronic renal insufficiency (matched to the transplanted group for level of renal function), and 33 hypertensives with normal renal function. anova, Student's t-test and simple regression analysis were used to analyse the data. Results: Transplanted patients showed higher valu…
Tumor Volume, CT Scan, Lymphography, Sonography, Intravenous Pyelography, and Tumor Markers in Testis Tumors
1989
Correlation of tumor volume to tumor stage in 134 patients with nonseminomatous testicular tumors, which were classified according to the TNM system, revealed similar tumor load for N0 and N1 patients. CT scans (n = 92), lymphangiography (n = 47), intravenous pyelography (IVP) (n = 134), sonography (n = 118) and serial tumor markers (n = 82) were evaluated for sensitivity, specificity and accuracy, both separately and in different combinations. The best individual results were obtained by lymphangiography (sensitivity 0.77, specificity 0.73, accuracy 0.75) and CT scan (sensitivity 0.52, specificity 0.91, accuracy 0.70). In combination CT scan and lymphangiography were the most valuable diag…
Biochemical interaction between effects of beclomethasone dipropionate and salbutamol or formoterol in sputum cells from mild to moderate asthmatics.
2005
Background: Several in vitro studies demonstrate that corticosteroids and long-acting β2 agonists may have a complementary and synergistic mode of action on the inflammatory processes in asthma. Methods: Sputum was induced in 20 mild to moderate asthmatic patients and the induced sputum cells (ISC) were cultured with beclomethasone dipropionate (BDP) 10−7 M, salbutamol 10−8 M and formoterol 10−8 M either alone or in combination, BDP plus salbutamol and BDP plus formoterol, for 24 h. We measured the levels of growth macrophages-colony stimulating factor (GM-CSF), released on activation normal T cells expressed and activated (RANTES) and interleukin-8 (IL-8), in the supernatant of stimulate…

De novo 15q21.1q21.2 deletion identified through FBN1 MLPA and refined by 244K array-CGH in a female teenager with incomplete Marfan syndrome
2010
International audience; Interstitial deletions involving the 15q21.1 band are very rare. Only 4 of these cases have been studied using molecular cytogenetic techniques in order to confirm the deletion of the whole FBN1 gene. The presence of clinical features of the Marfan syndrome (MFS) spectrum associated with mental retardation has been described in only 2/4 patients. Here we report on a 16-year-old female referred for suspicion of MFS (positive thumb and wrist sign, scoliosis, joint hyperlaxity, high-arched palate with dental crowding, dysmorphism, mitral insufficiency with dystrophic valve, striae). She had therefore 3 minor criteria according to the Ghent nosology. She also had speech …
Transforming Growth Factor Beta 1 Serum Levels in Patients with Preinvasive and Invasive Lesions of the Breast
2004
Transforming growth factor beta (TGF-beta)1 is thought to be involved in breast carcinogenesis. TGF-beta1 acts in an antiproliferative manner in the early stages of breast carcinogenesis, but promotes tumor progression and metastases in the advanced stages of the disease. No data have been published on serum TGF-beta1 in breast cancer. We investigated TGF-beta1 serum levels in patients with breast cancer (n=135), ductal carcinoma in situ (DCIS) I to III (n=67) or fibroadenoma (n=35), and in healthy women (n=40) to determine its value as a differentiation marker between malignant, pre-invasive and benign diseases and as a predictive marker for metastatic spread. Median (range) TGF-beta1 seru…
Blood sulfur-amino acid concentration reflects an impairment of liver transsulfuration pathway in patients with acute abdominal inflammatory processes
2001
Whole-blood free amino acids were measured in a control group made up of eight healthy women fasted for 12 h and also in eight patients with acute pancreatitis, five patients with acute cholecystitis and seven patients with acute appendicitis. Blood was withdrawn immediately on admission to hospital and again 3 d later following a controlled peripheral parenteral nutrition diet; this is with the exception of the appendicitis group. L-CYSTATHIONINE AND l-methionine concentrations were significantly higher in pancreatitis and appendicitis patients when compared with controls. In the pancreatitis and cholecystitis patients, l-serine concentration was also significantly higher when compared wit…
Induction of bone morphogenetic protein-6 in skin wounds. Delayed reepitheliazation and scar formation in BMP-6 overexpressing transgenic mice.
1998
Growth factors of the transforming growth factor-beta superfamily are involved in cutaneous wound healing. In this study we analyze the expression of the bone morphogenetic protein-6 (BMP-6) gene, a transforming growth factor-beta related gene, in skin wounds. In normal mouse skin high levels of BMP-6 mRNA and protein are expressed by postmitotic keratinocytes of stratified epidermis until day 6 after birth. BMP-6 expression is strongly reduced in adult epidermis with diminished mitotic activity. After skin injury we found large induction of BMP-6-specific RNA and protein in keratinocytes at the wound edge and keratinocytes of the newly formed epithelium as well as in fibroblast shaped cell…
Interferon-beta exposure during first trimester is safe in women with multiple sclerosis-A prospective cohort study from the German Multiple Sclerosi…
2015
Background: Available data suggest that pregnancy exposure to interferon-beta might result in lower mean birth weight and preterm birth. Objective: To determine the effect of interferon-beta exposure during pregnancy on pregnancy outcomes in multiple sclerosis patients. Methods: We compared the pregnancy outcomes of women exposed to interferon-beta with pregnancies unexposed to disease-modifying therapies. Women were enrolled into the German Multiple Sclerosis and Pregnancy Registry. A standardized questionnaire was administered during pregnancy and postpartum. Detailed information on course of multiple sclerosis and pregnancy, concomitant medications, delivery, and outcome of pregnancy was…
High progesterone levels in women with high ovarian response do not affect clinical outcomes: a retrospective cohort study
2014
Background The potentially detrimental role of progesterone during the follicular phase has been a matter of controversy for several years; however, few studies have analyzed the effects of combined raised estradiol and progesterone levels on pregnancy outcomes. The aim of the present study was to determine the influence of high progesterone levels on clinical outcomes in the context of high ovarian response. Methods We performed a retrospective cohort study that included 2850 women classified as high responders. The women were subdivided into six groups depending on their progesterone concentration on the day of human chorionic gonadotropin (hCG) administration: 1.81 ng/ml (>p90). Ovarian …
