Abstract
AIMS The first phase of this study aimed to determine the causes of persistent microalbuminuria after treatment with renin-angiotensin axis (RAA) blocking drugs. In a second phase we tried to determine if strict control of blood pressure and intensive RAA blockade could induce remission or reduction of microalbuminuria in clinical (primary care) practice. PATIENTS AND METHODS The study included both diabetic patients and non-diabetic hypertensive patients treated with RAA drugs in the presence of microalbuminuria. 211 patients were recruited (mean age 66.6±11.3 years, 111 men, 117 were diabetic). In the first phase treatment was optimized at standard doses. In the second phase treatment was increased during a three months period to reach a blood pressure (BP) < 130/80 mmHg by adding other antihypertensive treatment and to obtain maximal RAA blockade using long-acting drugs, increased dosage, or adding further medication at night. RESULTS Initial mean BP was 141±16/81±11 mmHg. BP control was unsatisfactory (control of systolic blood pressure [SBP] 19.3%; diastolic blood pressure [DBP] 37.6%). Dosage of RAA blocking drugs was inadequate in 21% of patients. Only 27.4% of patients were taking antihypertensive drugs at night. 30.1% of patients took once daily short acting drugs. During the studymean SBP was reduced to 137±13 mmHg (p < .001) and DBP decreased to 79±10 mmHg (p < .001). Control of SBP improved to 24.5% and DBP control went to 44.4%. Mean microalbuminuria decreased from 64.4±47.0 mg/day to 50.1±53.0 mg/day (p < .001) and the prevalence of microalbuminuria was reduced to 59.1%. CONCLUSIONS Persistent microalbuminuria was associated with poor blood pressure control and inadequate drug dosage. Low frequency of administration of drugs at night and inappropriate once-daily pills intake were frequent. Strict control of blood pressure and intensive RAA blockade significantly reduced the prevalence of microalbuminuria.

Abstract
OBJECTIVE It has been considered a study of nutritional menus offered at noon School in Granada. Balanced diet in children and youth will enable the prevention of diseases in adulthood. Comparing the menus prepared on school and the services offered by catering. MATERIAL AND METHODS The menus are aimed at 5,399 children from Granada, analyzed 354 school menus from 29 centres, public and private schools. Eleven colleges have their own kitchen, while 18 had hired a catering service. The amounts provided in each menu were estimated using standardized photographs of different sizes ration identified by those responsible for the dining room or by weighing Served directly from the ration. Nutritional assessment was determined by software, and the statistical treatment with the program SPSS v. 15.0. RESULTS There were statistically significant differences in the intakes of energy and nutrients from the menus developed in the centres and catering services. In the catering firms, the available energy and nutrition is similar, and in the menus prepared at the centres, there are significant differences in relation to some nutrients, depending on whether public school or private. CONCLUSIONS The energy, protein and lipid is high and low input from carbohydrates. It is the frequency of excessive consumption of meat and derivatives. To balance the diet of school, it is necessary to complement the menu of midday meals with the rest of the day.

Abstract
BACKGROUND Early prediction of proximal left anterior descending coronary artery (LAD) occlusion is essential from a clinical point of view HYPOTHESIS To develop an electrocardiogram (ECG) algorithm based on ST-segment deviations to predict the location of occlusion of LAD as a culprit artery. METHODS ECG and angiographic findings were correlated in 100 patients with an ST-segment elevation myocardial infarction (MI) in precordial leads V(1), V(2), and V(4) through V(6). RESULTS ST-depression > or = 2.5 mm in leads III + ventricular fibrillation (VF) presents sensitivity (SE) of 77% and specificity (SP) of 84% for LAD occlusion proximal to the first diagonal artery (D1). ST-segment in III + VF isoelectric or elevated, presents SE of 44% and SP of 100% for LAD occlusion distal to D1. Subsequent analysis of the equation summation operator of ST-deviation in VR + V(1) - V(6) < 0, allows us to predict occlusion distal to first septal artery (S1) with 100% SP. On the other hand, any ST-depression in III + VF > 0.5 mm + summation operator of ST-deviation in VR + V(1) - V(6) > or = 0 identifies a high-risk group (lower ejection fraction, worse Killip findings, higher peak of CPK and CK-MB, and major adverse cardiac events [MACE]: death, reinfarction, recurrent angina, persistent left ventricular failure, or sustained ventricular arrhythmia during hospitalization). CONCLUSIONS This sequential ECG algorithm based on ST-segment deviations in different leads allowed us to predict the location of occlusion in LAD with good accuracy. Cases with proximal LAD occlusion present the most markers of poor prognosis. We recommend the use of the algorithm in everyday clinical practice.

Abstract
UNLABELLED In comparison with hip fractures, increased expression of genes in the Wnt pathway and increased Wnt activity were found in bone samples and osteoblast cultures from patients with osteoarthritis, suggesting the involvement of this pathway in subchondral bone changes. No consistent differences were found in the genetic association study. INTRODUCTION This study aims to explore the allelic variations and expression of Wnt pathway genes in patients with osteoporosis and osteoarthritis. METHODS The expression of 86 genes was studied in bone samples and osteoblast primary cultures from patients with hip fractures and hip or knee osteoarthritis. The Wnt-related activity was assessed by measuring AXIN2 and in transfection experiments. Fifty-five SNPs of the LRP5, LRP6, FRZB, and SOST genes were analyzed in 1,128 patients. RESULTS Several genes were differentially expressed in bone tissue, with the lowest values usually found in hip fracture and the highest in knee osteoarthritis. Overall, seven genes were consistently upregulated both in tissue samples and in cell cultures from patients with knee osteoarthritis (BCL9, FZD5, DVL2, EP300, FRZB, LRP5, and TCF7L1). The increased expression of AXIN2 and experiments of transient transfection of osteoblasts with the TOP-Flash construct confirmed the activation of Wnt signaling. Three SNPs of the LRP5 gene and one in the LRP6 gene showed marginally significant differences in allelic frequencies across the patient groups, but they did not resist multiple-test adjustment. CONCLUSIONS Genes in the Wnt pathway are upregulated in the osteoarthritic bone, suggesting their involvement not only in cartilage distortion but also in subchondral bone changes.

Abstract
INTRODUCTION The phytoestrogens are naturally occurring compounds that are part of many foods of plant origin and could therefore modulate aspects related hormones, such as type of antioxidant reactions, learning about intakes of these compounds in different populations clarify important aspects on their responses on the human body. OBJECTIVE To evaluate the exposure of phytoestrogens through diet, in a sample of women of all ages belonging to the university community (teachers, students and administrative), residents in the province of Granada, Spain. MATERIAL AND METHOD 52 adult females, aged between 20 and 63 years completed a questionnaire individually Frequency of Food Consumption (FFQ) composed of a total of 144 foods. It weighted the total daily consumption of phytoestrogens standardizing these values referring to the daidzein as substance pattern (mg/day). Statistical analysis was performed using SPSS 15.0 (SPSS Inc., Chicago, IL, USA), with a level of significance of p < 0.05. RESULTS The results show that the total intake of phytoestrogens was (0.89 mg/day), and most of phytoestrogens was consumed in the form of lignanos. The total consumption of isoflavones, was 0.12 mg/day, of lignanos was 1.32 mg/day intake coumestrol was not significative. A linear regression analysis determined the equation to calculate intake phytoestrogens took into account 9 food groups (R: 0.918; p < 0.001). DISCUSSION Average intake of phytoestrogens in Spain, is comparable to intakes reported by similar studies in Germany, England and the United States (< 1 mg/ day). CONCLUSIONS There were no significant differences in the intake of phytoestrogens, when comparing results by age, educational level, marital status or physical activity. The intake of phytoestrogens (mg/day) can be estimated from the intake (g/day) from 9 food groups.

Abstract
Graphene has emerged as an electronic material that is promising for device applications and for studying two-dimensional electron gases with relativistic dispersion near two Dirac points. Nonetheless, deviations from Dirac-like spectroscopy have been widely reported with varying interpretations. Here we show evidence for strain-induced spatial modulations in the local conductance of single-layer graphene on SiO(2) substrates from scanning tunneling microscopic (STM) studies. We find that strained graphene exhibits parabolic, U-shaped conductance vs bias voltage spectra rather than the V-shaped spectra expected for Dirac fermions, whereas V-shaped spectra are recovered in regions of relaxed graphene. Strain maps derived from the STM studies further reveal direct correlation with the local tunneling conductance. These results are attributed to a strain-induced frequency increase in the out-of-plane phonon mode that mediates the low-energy inelastic charge tunneling into graphene.

Abstract
INTRODUCTION To perform a balanced diet adapted to the needs of the different life stages is important for a correct peopleís physical and psychological growth, preventing disease, and obtaining an optimal health status. The industrialized society is characterized by unbalanced energy balance due to an increase of energy intake through foods and decreased energy waste with increased SFA consumption. OBJECTIVE To assess average dietary intake and how certain demographical and socio-economic factors have an influence on dietary habits of a sample of schoolchildren from Granada city. METHODS The study population comprises 3,190 children and adolescents schooled at Granada city, with ages comprised between 8 and 15 years. A previously validated specific questionnaire was created including lifestyle habits, dietary habits, 24-hour recall, and frequency of foods consumption. RESULTS AND DISCUSSION The average caloric ingestion in this population is higher than the predicted average waste recommended by WHO, with higher energy values being found in males. The caloric profile found in our sample is clearly unbalanced. The main protein sources were meats and dairy products. There were high intakes of SFA, PUFA, and cholesterol, markedly surpassing the recommended values. Vitamin E intake did not reach the daily recommended values. With regards to dietary habits, the study population spends less than 30 minutes for breakfast and about half an hour for lunch and dinner, those spending more time for meals having the highest energy and proteins intake.

Abstract
OBJECTIVE The purpose of this series was to describe the ultrasonographic perfusion pattern in patients with brain death. METHODS Thirteen patients with different neurologic disorders in whom brain death developed were studied. Transcranial perfusion was analyzed after injection of 2.5 mL of a sulfur hexafluoride ultrasonographic contrast agent. Time-intensity curves were analyzed in predetermined regions of interest. RESULTS In all patients, analysis of regions of interest showed no bolus-like curve progression. This finding implies a complete absence of cerebral perfusion. CONCLUSIONS Patients with brain death studied by ultrasonographic perfusion techniques have a characteristic pattern.

Abstract
The latex agglutination immunoassay technique uses polymer colloids as carriers for antibodies or antigens to enhance the immunological reaction. In this work, the interaction of a lipopolysaccharide (LPS) of Brucella Melitensis with two conventional latexes has been studied. Some experiments on the physical adsorption of the LPS onto these polystyrene beads have been performed and several complexes with different coverage degrees were obtained by modifying the incubation conditions. Regarding the application in the development of diagnostic test systems, it is advisable to study the latex-LPS complexes from an electrokinetic and colloidal stability point of view. The complexes were electrokinetically characterized by measuring the electrophoretic mobility under different redispersion conditions. The colloidal stability was determined by simple turbidity measurements. Experimental and theoretical data have been employed to study the molecular disposition of the LPS in the latex particle surface to compare with the outer membrane of bacterial cells. Latex complexes covered by different LPS amounts showed high colloidal stability and adequate immunoreactivity that remains for a long time period.

Abstract
Four of 10 heifers that survived an episode of lead poisoning caused by an old broken battery in the pasture were periodically monitored from days 14 to 205 after the episode, with the aim of (i) determining the time-course of lead clearance from blood; and (ii) assessing whether the exposed cattle showed changes in haematological parameters or serum markers of hepatic and renal function (e.g. serum creatinine level) that might be useful as indicators of subclinical toxicity. On the first sampling day, lead levels in blood varied between 0.478 and 0.758 mg/l. The half-life of lead in blood was rather variable, ranging from 68 to 266 days. Despite the high blood lead levels, no significant changes were detected in haematological parameters or hepatic/renal markers, all of which remained within normal ranges. In conclusion, these cattle that survived an episode of lead poisoning may constitute a risk for human consumers, but do not appear to have suffered severe health consequences themselves.

Abstract
A chromosomal DNA fragment of 7.8 kb from Lactobacillus coryniformis CECT 5711 was cloned in Escherichia coli K-12 and was found to express a functional beta-galactosidase. Nucleotide sequence analysis showed that this fragment contained two partially overlapping genes, the lacL (1,881 bp) and the lacM (960 bp), that encode the subunits of a heterodimeric beta-galactosidase, with estimated molecular masses of 72,129 and 35,233 Da, respectively. Other three incomplete open reading frames showing homology to another beta-galactosidase, an alpha-galactosidase, and a galactokinase, respectively, were also found. The L. coryniformis beta-galactosidase was overproduced in E. coli by using an isopropyl-beta-D: -thiogalactopyranoside (IPTG) expression system. Two new proteins with an estimated M (r) s of approximately 72,000 and 35,000 appeared upon induction with IPTG, and extracts of the recombinant E. coli strain showed beta-galactosidase activity.
