Podocytes are highly specialized epithelial cells that form part of the filtration barrier in the kidney, and their loss reflects a malfunction in glomerular filtration, which is usually associated with the progression of the disease. Glomerulonephritis is a serious complication that develops in about 50% of the lupus patients and is characterized by(More)
Expression of estrogen receptors (ER) is clinically relevant in designing therapeutic strategies. The relative importance of the two types of estrogen receptors (ER-alpha and ER-beta) in human breast cancers in pre- and post-menopausal women has not been properly defined. To determine the possible association between the expression of estrogen receptor and(More)
This study was performed to clarify the role of soluble Fas (sFas) in lupus nephritis (LN) and establish a potential relationship between LN and the -670 polymorphism of Fas in 67 patients with systemic lupus erythematosus (SLE), including a subset of 24 LN patients with proteinuria. Additionally, a group of 54 healthy subjects (HS) was included. The(More)
The human prostate is a gland composed of many types of cells and extracellular components with specific functions. The stromal compartment includes nerve tissue, fibroblasts, lymphocytes, macrophages, endothelial cells, and smooth muscular cells. The epithelial compartment is composed of luminal epithelial cells, basal cells, and a lesser number of(More)
Although ghrelin in cord blood has been associated to birth weight, its role in fetal and postnatal growth has not been elucidated. The aim of this study was to analyze total ghrelin, acyl ghrelin (AG), and des-acyl ghrelin (DAG) in cord blood of newborns with idiopathic birth weight alterations, and to evaluate protein expression of placental GHS-R1, in(More)
BACKGROUND Uterine sarcomas are rare but extremely aggressive malignant uterine pathology; mostly incidentally diagnosed at an advanced stage, with a higher aggressiveness and poor prognosis. OBJECTIVE To determine the epidemiological profile of women with this diagnosis in Ginecopediatria Hospital, UMAE 48 of IMSS and its correlation with the literature.(More)
OBJECTIVE The molecular mechanism of citrullination involves the calcium-dependent peptidylarginine deiminase (PAD) family of enzymes. These enzymes induce a stereochemical modification of normal proteins and transform them into autoantigens, which in rheumatoid arthritis trigger a complex cascade of joint inflammatory events followed by chronic synovitis,(More)
Alterations in birth weight impact postnatal outcome and adult metabolic health. Therefore, fetal growth regulation is crucial for preventing chronic metabolic diseases. Leptin has been suggested to play an important role in placental and fetal growth, albeit its specific mechanisms of action have not been elucidated. The aim of this study was to analyze(More)
