Effective clearance of apoptotic cells by macrophages is essential for immune homeostasis. The transcriptional pathways that allow macrophages to sense and respond to apoptotic cells are poorly defined. We found that liver X receptor (LXR) signaling was important for both apoptotic cell clearance and the maintenance of immune tolerance. Apoptotic cell(More)
BACKGROUND The Functional Imaging Biomedical Informatics Network is a consortium developing methods for multisite functional imaging studies. Both prefrontal hyper- or hypoactivity in chronic schizophrenia have been found in previous studies of working memory. METHODS In this functional magnetic resonance imaging (fMRI) study of working memory, 128(More)
INTRODUCTION Auditory hallucinations are a hallmark symptom of schizophrenia. The neural basis of auditory hallucinations was examined using data from a working memory task. Data were acquired within a multisite consortium and this unique dataset provided the opportunity to analyze data from a large number of subjects who had been tested on the same(More)
Shiga-like toxin-producing Escherichia coli have been associated with hemorrhagic colitis and the hemolytic uremic syndrome (HUS). Because Argentina has the highest reported frequency of HUS in the world, Argentine children were prospectively studied during the HUS seasons for evidence of Shiga-like toxin-related diseases. On the basis of serology, fecal(More)
In many studies in which the relationship between blood pressure and blood lead level has been examined, investigators have found significant--but small--associations. There was only one previous report of a significant association of blood lead with blood pressure in pregnant women. We measured blood lead level and sitting blood pressure of 1,627 women in(More)
The evolution of digestive proteases during larval development of Rhynchophorus ferrugineus (Olivier, 1790) has been studied. A progressive increase of protease activity has been found. The optimum pH for proteolytic activity against azocasein was determined. Caseinograms revealed an active complex of alkaline proteases from the early stages of the(More)
A constitutional chromosomal aberration was diagnosed in 38/163 (23.3%) azoospermic patients. Whereas the 47,XXY complement was the commonest (31/38 cases), the following abnormal karyotypes were also found: 46,XX; 46,X,del(Y) (q11); 46,X,r(Y); 46,XY,inv(1) (p3500q21.3)mat; and 46,Y,t(X;3) (q26;q13.2)mat (both the deleted and the annular Y were observed(More)
We examined bone lead contribution to blood lead in a group of 311 immigrant women, 99% from Latin America, during the third trimester of pregnancy and 1 to 2 months after delivery. We measured in vivo tibia and calcaneus (heel) bone lead concentration in the postdelivery period with K shell X-ray fluorescence. Prenatal and postnatal geometric mean (range)(More)
BACKGROUND The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. METHODS Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting(More)
BACKGROUND To study the clinical features of Wilson's disease in childhood. METHODS Retrospective review of the clinical, laboratory, and histologic features and prognosis of Wilson's disease in 26 Spanish children. RESULTS The first medical visit, at age 9.8+/-3.4 years (range, 4-16 years), was prompted by liver dysfunction detected accidentally (61%),(More)
