Abstract
Public spaces are considered areas that promote users' physical and mental health. The role of these people in public spaces makes it necessary to evaluate such areas. In this study, 12 urban parks on the island of Tenerife were evaluated, combining the assessment of a trained observer and the perception of users, to analyse and categorise the environmental quality of the parks. The findings of this study conclude that users are good evaluators of public spaces; that the Public Space Characteristics Observation Questionnaire (PSCOQ) tool allows the classification of public spaces and that physical order is capable of predicting the environmental quality and the restorative capacity of spaces, as perceived by users. The PSCOQ observation tool makes it possible to detect the strengths and weaknesses of public spaces so they can be improved and adapted to the needs of users.

Abstract
OBJECTIVES Inequalities have been reported between high, middle and low socioeconomic position (SEP) children. However, the effect of contextual and individual SEP on existing inequalities among socioeconomically deprived children varies between local contexts. The aim of this study was to assess the impact of contextual and individual SEP on individual caries experience among socioeconomically deprived children in Chile. METHODS Cross-sectional multilevel analysis of data from the 2015 electronic register of the National Board of School Aid and Scholarships (JUNAEB) of Chile. The contextual variables were the municipality Human Development Index (HDI) and rurality index. Individual variables included gender, living in extreme poverty and school grade. Multilevel negative binomial models assessed their impact on DMFT/dmft. RESULTS 112,429 children in 255 municipalities were included. Overall, contextual SEP (HDI) was not associated with caries experience in the primary or permanent dentition. Individual SEP (living in extreme poverty) was associated with caries experience in both dentitions. The proportion of children living in extreme poverty with caries experience in the primary teeth was 17% higher than children not living in extreme poverty (PR 1.17; 95% CI 1.15-1.19), while for children with permanent teeth it was 9% higher (PR 1.09; 95% CI 1.08-1.11). CONCLUSION These findings could support the development of health strategies focused on individual SEP to efficiently reduce oral health inequalities among socioeconomically deprived children.

Abstract
Improving the thermal efficiency of internal combustion engines is essential to reduce the operating costs and complaints with the increasing environmental requirements. Thermoelectric generators came up as an opportunity to reuse part of the heat loss with the exhausts. This paper evaluates the performance of a thermoelectric generator to improve the efficiency of a stationary diesel engine under different rotational speeds and torques. The data was obtained through CFD simulations and validated with experiments. The proposed solution uses a cooling system to control the temperature of the thermoelectric modules. The results show that the torque and the rotational speed of the engine are the most significant performance parameters of the thermoelectric generator, while the influence of the cooling water temperature has a minor but still significant influence. Additionally, the results show a change from 1.3% to 6.2% in the thermoelectric generator efficiency, while the exergy efficiency varies between 1.8% and 7.9%. The exergy balance indicates that most of the exergy is loss because of the irreversibilities in the thermoelectric generator and of the exergy loss with the exhausts. The exergy loss can be reduced by optimizing the design of the heat exchanger. Since the thermoelectric generator improved the engine efficiency by a marginal 0.2%-0.8%. Therefore, it is important to further research how to improve the design of heat exchangers for thermoelectric generators to increase their energy conversion efficiency and their impact on the energy efficiency of internal combustion engines.

Abstract
Parasites alter the reproductive performance of their hosts, limit their growth, and thereby modify the energy budget of these hosts. Experimental studies and theoretical models suggest that the outcome of the host-parasite interactions could be determined by ecological factors such as food availability levels in the local habitats. Nutrient inputs may affect the host's food resource availability with positive or negative effects on parasite infection rates and tolerance of infection, however this has not been specifically evaluated in natural systems. In this study, we evaluate the effects of parasitism by Proctoeces humboldti on body size, gonadosomatic index (GSI), and metabolic rate (oxygen consumption) of their second intermediate host Fissurella crassa limpets, under contrasting natural conditions of productivity (upwelling center vs upwelling shadow sites). Our results evidenced that parasitized limpets collected from the intertidal habitat influenced by coastal upwelling site showed greater shell length, muscular foot biomass and GSI as compared to non-parasitized limpets collected in the same site, and compared to parasitized and non-parasitized limpets collected from the sites under the influence of upwelling shadow conditions. Oxygen consumption was lower in parasitized limpets collected from the upwelling-influenced site than in the other groups, independent of age, suggesting reduced metabolic stress in infected individuals inhabiting these productive sites. Our results suggest that increased productivity in upwelling sites could mitigate the conflict for resources in the P. humboldti - F. crassa system, influencing where such interaction is found in the continuum between parasitism and mutualism. Since parasitism is ubiquitous in natural systems, and play important roles in ecological and evolutionary processes, it is important to analyze host-parasite interaction across a variety of ecological conditions, especially in biological conservation.

Abstract
INTRODUCTION We analyze the effectiveness and safety of a specific analgosedation protocol for procedures, and eva luate the satisfaction of the health personnel with each procedure. PATIENTS AND METHOD Prospective study of an analgosedation protocol for hospital procedures in children under 18 years of age, with an individualized strategy based on the patient's baseline situation, the type of procedure and the experience of the pediatrician responsible for the sedation. The following variables were recorded: diagnosis motivating the procedure, type of procedure, anthropometric data, allergies, medication, ASA status and baseline disease, fasting time, lung auscultation, temperature, oxygen saturation, res piratory rate, heart rate, blood pressure, sedation location, type of drug, dose, route of administra tion, Ramsay sedation scale, duration of sedation, type and treatment of adverse effects, presence of family members throughout the procedure, and patient satisfaction. RESULTS 279 sedations were performed. The most commonly used drugs were nitrous oxide (62.7%) and midazolam (16.5%); the most commonly used routes of administration were the inhaled one (62.4%) and the intravenous one (15.8%). The satisfaction was high for the pediatrician (92.5%), the nurse (94.3%), the family (96.8%), and patients (93.6%), with a good correlation between them, and it was significantly lower when using midazolam and the nasal and oral routes. The adverse effects rate was 3.2%, and none was severe. CONCLUSIONS The implementation of a specific analgosedation protocol for procedures in the hospital environment achieves high levels of effectiveness and safety, as well as a high level of satisfaction, both in family members and in health personnel.

Abstract
Abstract
A revised method to determine solubility of nitrogen in dilute pepsin, using 0.0002% pepsin in place of 0.2% in AOAC Official Method 971.09, was tested in 16 laboratories with 12 samples of fishmeal. Results were calculated according to 2 procedures: AOAC Official Method 971.09 and a method described in 1964 by researchers at the Torry Research Station (Aberdeen, Scotland), and generally referred to as the modified Torry method. Variations in the method of shaking and source of pepsin were also investigated. Pepsin solubility values were lower and more variable when calculated by the Torry procedure. The method of shaking apparently affected the result when calculated according to the Torry but not the AOAC method. The source of pepsin had no significant effect on between-laboratory variability, but a comparison of the 2 main sources within one laboratory resulted in highly significant differences. Based on this study, the International Fishmeal and Fish Oil Organization has adopted this new method, using 0.0002% pepsin but keeping the AOAC method of calculation. The type of shaker and source of pepsin are recommended but are not mandatory. The repeatability and reproducibility limits of this new method are 1.6 and 3.3% units of solubility, respectively.

Abstract
The main component of Alzheimer's disease (AD) is the amyloid-beta peptide (Aβ), the brain of these patients is characterized by deposits in the parenchyma and cerebral blood vessels known as cerebral amyloid angiopathy (CAA). On the other hand, the platelets are the major source of the Aβ peptide in circulation and once secreted can activate the platelets and endothelial cells producing the secretion of several inflammatory mediators that finally end up unchaining the CAA and later AD. In the present study we demonstrate that cAMP/PKA pathway plays key roles in the regulation of calpain activation and secretion of Aβ in human platelets. We confirmed that inhibition of platelet functionality occurred when platelets were incubated with forskolin (molecule that rapidly increased cAMP levels). In this sense we found that platelets pre-incubated with forskolin (20 μM) present a complete inhibition of calpain activity and this effect is reversed using an inhibitor of protein kinase A. Consequentially, when platelets were inhibited by forskolin a reduction in the processing of the APP with the consequent decrease in the Aβ peptide secretion was observed. Therefore our study provides novel insight in relation to the mechanism of processing and release of the Aβ peptide from human platelets.

Abstract
This work examined changes in color that can be explained solely on the basis of the total myoglobin content and the relative proportions of deoxymyoglobin, oxymyoglobin (OMb) and metmyoglobin (MMb) during storage of meat. Meat color was evaluated for L*, a*, b*, C* and hab. Total pigment content was measured from the reflex attenuance at 525 nm (A525). The relative proportions of each pigment was determined using two different methods: the Krzywicki method based on the reflex attenuance values at 473, 525, 572 and 700 nm and the KS method based on K/S ratios of the absorption and scattering coefficients (K/S)474 ÷ (K/S)525, (K/S)572 ÷ (K/S)525 and (K/S)610 ÷ (K/S)525. The study was performed on beef (Longissimus lumborum) samples measured after 1, 4 and 7 days of exposure to air. Result revealed that L* values can be fully explained by A525 alone. C* and a* were well explained by those parameters related to OMb content. The other color parameters depended on pigment forms. The KS method gave better results. The parameters related to MMb content were relevant to classify samples according to the time of exposure to air. In any case, information provided by color and pigment parameters were complementary to each other.

Abstract
Objective To generate a global reference for caesarean section (CS) rates at health facilities. Design Cross‐sectional study. Setting Health facilities from 43 countries. Population/Sample Thirty eight thousand three hundred and twenty‐four women giving birth from 22 countries for model building and 10 045 875 women giving birth from 43 countries for model testing. Methods We hypothesised that mathematical models could determine the relationship between clinical‐obstetric characteristics and CS. These models generated probabilities of CS that could be compared with the observed CS rates. We devised a three‐step approach to generate the global benchmark of CS rates at health facilities: creation of a multi‐country reference population, building mathematical models, and testing these models. Main outcome measures Area under the ROC curves, diagnostic odds ratio, expected CS rate, observed CS rate. Results According to the different versions of the model, areas under the ROC curves suggested a good discriminatory capacity of C‐Model, with summary estimates ranging from 0.832 to 0.844. The C‐Model was able to generate expected CS rates adjusted for the case‐mix of the obstetric population. We have also prepared an e‐calculator to facilitate use of C‐Model (www.who.int/reproductivehealth/publications/maternal_perinatal_health/c-model/en/). Conclusions This article describes the development of a global reference for CS rates. Based on maternal characteristics, this tool was able to generate an individualised expected CS rate for health facilities or groups of health facilities. With C‐Model, obstetric teams, health system managers, health facilities, health insurance companies, and governments can produce a customised reference CS rate for assessing use (and overuse) of CS. Tweetable abstract The C‐Model provides a customized benchmark for caesarean section rates in health facilities and systems. The C‐Model provides a customized benchmark for caesarean section rates in health facilities and systems.

Abstract
In this work we obtain general expressions for the complex refractive indices of refracted waves as a function of the angle of incidence in the case of an electromagnetic wave propagating in a transparent isotropic medium that reaches an interface with a biaxial absorbing medium. The biaxial absorbing medium is only required to have a diagonalizable complex dielectric tensor. Obtained expressions can be applied to any orientation of the principal axes and can be specialized for isotropic, uniaxial or biaxial, or transparent or absorbing media. By using these expressions we have also obtained the surface of indices and the surface of absorption coefficients for an example of a biaxial absorbing medium.

Abstract
BACKGROUND Besides the development of new markers and diagnostic criteria for rheumatoid arthritis (RA), many patients are still diagnosed after several years of symptoms. Oxidative stress markers are already increased at an early stage of RA. Our aim was to evaluate the additional diagnostic value of these markers. METHODS A case-control study was performed. Patients met the 1987 RA ACR criteria, less than 2 years of symptoms and no previous treatment with disease-modifying anti-rheumatic drugs (DMARD), steroids or vitamin E. Controls were selected from patient's relatives and matched (1:1) by gender, age, and current smoking habit. Oxidative damage markers were malonyldialdehyde (MDA), Lipid hydroperoxides (LOOH) and Carbonyl proteins (CP). Statistical analysis was performed in agreement with the STARD initiative. RESULTS Sixty-five RA patients without treatment and 65 healthy controls were included. LOOH, CP, antibodies against citrullinated peptides (anti-CCP) and rheumatoid factor (RF) were significantly higher in patients, and MDA higher in controls. The same results were obtained in the subgroups of patients who smoke or not, and in anti-CCP positive or negative. The diagnosis performance of traditional markers showed good specificity but low sensitivity. The addition of LOOH and CP increased the sensitivity and the area under the receiving operating characteristic (ROC) curve especially in non-smoking (66%) and negative anti-CCP (51%) patients. CONCLUSIONS The separate or combined addition of LOOH or CP to the traditional disease markers improved the diagnosis of RA, especially in non-smoking or negative anti-CCP patients.

Abstract
In this chapter we describe how mass spectrometry-based quantitative protein measurements by multiple reaction monitoring (MRM) have opened up the opportunity for the assembly of large panels of candidate protein biomarkers that can be simultaneously validated in large clinical cohorts to identify diagnostic protein biomarker signatures. We outline a workflow in which candidate protein biomarker panels are initially assembled from multiple diverse sources of discovery data, including proteomics and transcriptomics experiments, as well as from candidates found in the literature. Subsequently, the individual candidates in these large panels may be prioritised by application of a range of bioinformatics tools to generate a refined panel for which MRM assays may be developed. We describe a process for MRM assay design and implementation, and illustrate how the data generated from these multiplexed MRM measurements of prioritised candidates may be subjected to a range of statistical tools to create robust biomarker signatures for further clinical validation in large patient sample cohorts. Through this overall approach MRM has the potential to not only support individual biomarker validation but also facilitate the development of clinically useful protein biomarker signatures.

Abstract
INTRODUCTION Rivastigmine, a treatment for mild to moderate Alzheimer disease (AD), is the first cholinesterase inhibitor to be available in the transdermal format. We aim to describe user experience and satisfaction with the rivastigmine patch, as well as any clinical changes perceived in patients. METHODS Observational, cross-sectional, multicentre study with 239 investigators and 1851 informal caregivers of patients with mild to moderate AD. Patients were treated with transdermal rivastigmine patches for ≥ 6 months and had previously received high doses of oral rivastigmine. RESULTS Mean caregiver age was 59.8±14.4 years and 70.9% were women. They spent 10.0±7.1hours per day providing care and 79.8% lived with the patient. Patch instructions were described as easy to follow by 97.1% of the caregivers and 92.1% of them rated patch application as easy or very easy. The most commonly cited disadvantage was adhesion problems (26.8%). Discontinuation of treatment was due to cutaneous reactions in most cases. Overall, 76.5% of the caregivers were satisfied or very satisfied with transdermal treatment and 77.4% considered that its interference with daily activities was minimal or null. The patch was preferred to oral treatment by 94.3% of caregivers. Clinical Global Impression of Change ratings improved according to 61.3% of the caregivers and 53% of the investigators. Few caregivers reported medication forgetfulness. CONCLUSIONS Most caregivers of patients with mild to moderate AD preferred the transdermal format of rivastigmine to the oral format. Caregivers also reported overall satisfaction, ease of use, and reduced impact on daily activities for transdermal rivastigmine format, in addition to patient improvement compared to their condition under the previous treatment.

Abstract
INTRODUCTION Alzheimer disease (AD) causes progressive cognitive decline leading to loss of independence for activities of daily living; rivastigmine is one of the drugs used for symptomatic management. OBJECTIVE To assess the therapeutic use of different pharmaceutical forms of rivastigmine in patients with AD in normal clinical practice. PATIENTS AND METHODS Cross-sectional, observational, multi-centre study conducted on patients with mild to moderate AD treated with rivastigmine in Spanish outpatient clinics specialising in Geriatrics, Psychiatry, and Neurology. Data regarding use of oral (OR) and transdermal (TDR) rivastigmine, compliance (degree of adherence), and caregiver satisfaction with treatment were evaluated. RESULTS In total, 2252 patients with a mean age of 77.2 years were included; 60.2% were women. AD was moderate to moderately severe in 58.4%. Rivastigmine treatment was started orally in 54.4% of the patients and transdermally in 45.6%; 35.6% of those who started treatment by the OR route switched to TDR. A single dose adjustment was sufficient for 77.5% of patients on TDR treatment vs 11.8% of patients receiving OR treatment. More patients on TDR treatment (80.8% vs. 57.1% on OR treatment) reached the maximum therapeutic dose of rivastigmine and did so in a shorter period of time (51.6 vs 205.8 days). Compliance rates (60.5% vs 47.2%) and caregivers' satisfaction with treatment (89.4% vs 81.9%) were also higher for TDR. CONCLUSIONS In normal clinical practice, using the TDR route of administration improves dose titration and drug compliance, allowing more patients to reach the maximum recommended dose of rivastigmine in a shorter time period.

Abstract
INTRODUCTION Several therapeutic options are available for the symptomatic treatment of Parkinson's disease (PD).There is no reliable information about which factors are involved in the choice of treatment. OBJECTIVE To identify factors contributing to the decision to start treatment with levodopa/carbidopa/entacapone (LCE) in patients with PD. PATIENTS AND METHODS We completed a descriptive cross-sectional retrospective multicentre study of patients with idiopathic PD receiving LCE. Clinical data were collected with special attention to factors that could potentially determine when to initiate treatment with LCE in normal clinical practice. RESULTS We studied 1050 patients with a mean age of 71.3±8.7 years (58.2% men). Average time from onset of symptoms to diagnosis was 13.8±12.9 months, with a latency time of 74.5±53.6 months before starting LCE treatment. The most common initial symptoms were tremor (70.6%), reduced dexterity (43.2%) and slowness of movement (41.5%). At the start of LCE treatment, most patients were in Hoehn and Yahr stage 2 (57.5%), with an average rating of 73.4% on the Schwab & England scale. Eight hundred twenty two patients (78.3%) received treatment with other drugs before starting LCE (mean time between starting any PD treatment and starting LCE was 40.5±47.2 months). Clinical factors with a moderate, marked, or crucial effect on the decision to start LCE treatment were bradykinesia (84.7%), daytime rigidity (72.2%), general decline (72.2%), difficulty walking (66.4%), tremor (62.7%), nocturnal rigidity (56.1%), and postural instability (53%). Difficulty performing activities of daily living was the only psychosocial factor identified as having an influence on the decision (84.3%). CONCLUSIONS The decision to start patients with idiopathic PD on LCE treatment is mainly determined by motor deficits and disabilities associated with disease progression.

Abstract
When a plane wave is incident from an isotropic medium into a uniaxial transparent medium so that the ordinary wave propagates in the direction of the optical axis, the extraordinary wave will also propagate in the same direction and with the same refractive index. We will show that this is not the case when the second medium is a uniaxial absorbing material. In this work, we will state a clear and precise interpretation of the meaning of propagation in the direction of the optical axis in the case of uniaxial absorbing media. Assuming that the ordinary wave is refracted in the direction of the optical axis we will analyze the refraction of the extraordinary wave and we will compare it with the case of transparent media. The necessary conditions to have both ordinary and extraordinary waves refracted in the direction of the optical axis will be obtained.

Abstract
High-altitude hypoxia generates spermiogram impairment due to germinal epithelium, Leydig cells, sperm and seminal plasma alterations, but precise mechanisms involved are unknown. The objective of this work was to analyse the effect of normobaric hypoxia on the morphology of testicular interstitium and some associated molecular and hormonal factors. Twenty-four mice were exposed to normobaric hypoxia (8.1% inspired oxygen fraction) during 20 days. The effects on body weight, testicular weight, vascularisation, testosterone, HIF1-α and VEGF were analysed at different periods of exposure and compared to controls. Hypoxic mice had lower body weight than mice kept in normoxia. Testicular weight raised significantly the 1st day, but remained normal during the rest of experiment. Number of blood vessels per field and mean diameter of vessels were higher in hypoxic mice. Plasmatic and testicular testosterone raised during first 24 h of hypoxia, but decreased on the 5th day. Vascular/interstitial ratio (proportion of interstice occupied by blood vessels) duplicated at the end of the experiment. Most substantial early effects of hypoxia were testicular oedema, increase in number and diameter of blood vessels and elevation of plasmatic and testicular testosterone. Normobaric hypoxia generates similar effects to those induced by hypobaric hypoxia.

Abstract
The objective of this paper is make recommendations for the perioperative management of antirheumatic treatment based on the best available evidence. A systematic review was performed including studies in which patients with rheumatic diseases treated with biological and non-biological disease-modifying antirheumatic drugs (DMARDs) had undergone surgery. A total of 5,285 studies were recorded, of which 27 were finally included. These contained information on 5,268 patients and 7,933 surgeries. The majority were women (mean age 55 years) were diagnosed with rheumatoid arthritis, and the most studied drug was methotrexate (MTX). The final recommendations include: maintaining treatment with MTX or leflunomide in the perioperative period in the absence of other risk factors for postoperative complications (Level of Evidence 1c, Grade D recommendation). Biological DMARDs should be temporarily suspended, or the surgery scheduled as far as possible from the last dose, and, if there were other risk factors a space at least two doses (Level of Evidence 2c; Grade D recommendation).

Abstract
In this work we study the anomalous negative refraction when a plane wave is incident from an isotropic medium to a uniaxial absorbing medium. We study the influence of the anisotropy on the refractive indices and the anisotropy on the absorption coefficients in the negative refraction of these materials. Negative refraction can occur for the ordinary and extraordinary waves for a wide range of values of the angle of incidence. The allowed values of the angle of incidence that lead to negative refraction are analyzed in detail as a function of the orientation of the optic axis and the values of the refractive indices and absorption coefficients.

Abstract
In this work we analyze the propagation of a plane wave that passes from an isotropic transparent medium to a uniaxial absorbing medium. Detailed expressions that give the real directions of propagation of the wave and the energy of the reflected and refracted ordinary and extraordinary waves are obtained. These expressions are valid for every orientation of the optic axis of the uniaxial medium and for every direction of propagation of the incident wave. Expressions are tested in the case of an interface between a transparent and an absorbing isotropic media and for the air-rutile (TiO2) interface. The effect of absorption has been evaluated by comparing the results obtained in rutile with the results obtained in a transparent uniaxial medium with the same real refractive indices. Results are presented for different values of the angle of incidence and the orientation of the plane of incidence.

Abstract
The addition of entacapone to levodopa-carbidopa (LC) or the switch from LC to a tablet containing levodopa-carbidopa-entacapone (LCE) improves the wearing-off phenomenon, increases the 'on' time and decreases the 'off' time, but the appearance or exacerbation of dyskinesias is the more frequent side-effect. Thus, a reduction of the total levodopa dosage would be recommended. However, this could result in a lack of efficacy against the wearing-off. We report on the results of a clinical trial conducted to determine the best way in terms of efficacy, tolerability and safety of switching from LC to LCE in patients with Parkinson's disease (PD) and end of dose wearing-off. 39 patients with PD and wearing-off without or with mild dyskinesias were randomly assigned to either a group receiving the same LC dosage or to a group in which the total LC amount was reduced by 15-25%. Four weeks after the change, both groups showed an increase in daily 'on' time and a reduction in the daily time spent in 'off'. Two patients in each group experienced an increase in basal dyskinesias. No differences in clinical assessment between groups were found. Tolerance was excellent. This study suggests that switching from LC to LCE in patients with mild-to-moderate wearing-off can be done safely with or without reducing the total LD amount, but in the clinical setting it would be more practical to keep the dosage of LC unchanged unless severe dyskinesias are present.

Abstract
The propagation of inhomogeneous and elliptically polarized plane waves in absorbing uniaxial anisotropic media is described using complex unitary vectors to represent the direction of propagation and the direction of polarization. Detailed expressions for electric displacement, electric field, and magnetic field vectors are obtained for the ordinary and extraordinary waves, and their geometry is discussed. According to the complex direction of propagation, three particular cases are studied: the real case (homogeneous wave), the case perpendicular to the optical axis, and the case coplanar with the optic axis. The case of isotropic media is also analyzed.

Abstract
This review of the historical course of anesthesia performed in the context of urology in Spain relies on primary sources: doctoral theses, dissertations, published articles, inaugural addresses, conference proceedings, and books belonging to various archives and libraries. We collected a large number of documents relating to urology and of particular interest regarding anesthesia, classified them, and subjected them to critical analysis. This allowed us to carefully follow the development of anesthesia and urology itself, both of which attained notable clinical and scientific importance in Spain. Anesthesia with chloroform and incomplete anesthesia were the norm during the second half of the 19th century. However, during the first half of the 20th century, the most widely used techniques were the application of ether or spinal or local infusions, although epidural and intravenous techniques were also mentioned.

Abstract
To evaluate the long-term effects of entacapone on both mean daily 'on' time and health-related quality of life (QoL) in patients with Parkinson's disease (PD) experiencing 'end-of-dose' motor fluctuations and the benefits of an early therapeutic intervention. A prospective, multicenter, observational, 12-month study was performed with an initial 3-month intervention phase, consisting of a phone call to half of the patients from randomly selected investigators to assess if dose adjustment was necessary. Effectiveness was determined by home diaries ('on' time), subscales II and III of the Unified Parkinson's Disease Rating Scale (UPDRS), and the Parkinson's Disease Questionnaire (PDQ-8). After 3 months of treatment, 4.0% of the intervention group patients discontinued the study, versus 18.4% in the control group (P < 0.01). The improvement in 'on' time was significantly increased since the 3-month visit (21%, P < 0.0001) until the end of the study (23% at 12 months, P < 0.0001). Entacapone also induced significant reductions in the UPDRS scores for subscales II and III and in the PDQ-8 score. 11.2% of patients experienced at least one adverse reaction. This study confirms the effectiveness of entacapone in reducing motor fluctuations by increasing 'on' time, and in improving QoL of PD patients. An early adjustment of entacapone and levodopa doses reduces the number of treatment discontinuations during the first months of treatment.

Abstract
Experimental murine cysticercosis caused by Taenia crassiceps has proved to be a useful model with which to test the efficacy of new vaccine candidates and delivery systems against pig cysticercosis. A high level of protection against murine cysticercosis was previously observed by intramuscular or intradermal DNA immunization with the use of the sequence of the recombinant KETc7 antigen cloned in pcDNA3 (pTc-sp7). To determine the effect of KETc7 differential expression in DNA vaccination, KETc7 was cloned in pGEM 11Zf(+) under the control of the tissue-specific regulatory promoter phosphoenolpyruvate carboxykinase (pPc-sp7). A high level of protection was induced by intrahepatic immunization with pPc-sp7, pTc-sp7 and the empty vector in the absence of any specific immunity. The empty vector pGEM 11Zf(+), the plasmid with the highest content of CpG sequences, provided to the most efficient protection. This protection was related to an increased number of splenocytes, enhanced nonspecific splenocyte proliferation, and intensified intrahepatic INF-gamma production. Overall, intrahepatic plasmid CpG-DNA immunization provokes an exacerbated nonspecific immune response that can effectively control Taenia crassiceps cysticercosis.

Abstract
The effects of increasing proportions of soybean soapstock (SSS) in laying hen diets on egg quality parameters and on the fatty acid (FA) composition of the yolk were studied. One hundred sixty Babcock B-300 x laying hens, 20 wk of age, were allotted to 5 dietary treatments comprising a control diet (D5) with soybean oil at 100% or SSS in proportions of 25% (D1), 50% (D2), 75% (D3), and 100% (D4) replacing the oil source in commercial-type diets throughout the 15-wk laying period. Egg quality parameters were recorded weekly. Four pooled yolks for each treatment were collected at 0, 9, and 15 wk, and their FA profiles were determined. Egg weight, shell thickness, shape index, and Haugh unit were not influenced by dietary treatment. The concentrations of saturated FA (SFA) in yolks were generally kept at a constant level, regardless of the percentage of SSS in the hen diets. Total monounsaturated FA (MUFA) content did not vary over the course of the experiment, except for C14:1. After 15 wk of feeding, the total polyunsaturated FA (PUFA) n-3 increased in yolks of all diets. Among the long-chain PUFA, the percentage of C20:4 (arachidonic acid) was less affected. Inclusion of 100% SSS allowed production of eggs with similar PUFA/SFA and n-6/n-3 ratios when compared with eggs from hens fed D5. As SSS represents one-third of the oil cost, its inclusion in layer diets could represent an important economic benefit.

Abstract
The aims of this retrospective study are to assess the prevalence of primary resistances to antiretroviral drugs, both reverse transcriptase and protease inhibitors in untreated patients from Spain, and to determine their possible association with several epidemiological variables. A total of 148 samples belonging to 145 patients were processed using the genotypic technique VERSANT HIV 1 (LiPA) in order to study the presence of mutations at codons 41, 69, 70, 74, 75, 103, 106, 151, 181, 184 and 215 of the reverse transcriptase gene (VERSANT HIV 1 RT) and at codons 30, 46, 48, 50, 54, 82, 84 and 90 of the protease gene (VERSANT HIV 1 Protease). The patients' epidemiological variables which could be relevant to HIV infection were also analyzed. The successful amplification rate was 77.70% for LiPA RT and 91.21% for LiPA P. In the case of LiPA RT, statistical significance (p < 0.05) was observed when successful amplification was related to viral load level (p < 0.001). Global prevalence of resistance was 20.27%. Mutations in the reverse transcriptase gene were found in eight samples (5.40%). Using LiPA P, mutations were detected in 16.21% of cases, with V82A being the most frequently detected mutation (15/24, 62.50%) in nine samples. The V82A mutation was found alone (66.6%) and it was found together with the I84V mutation in five samples (20.83%). I84V was the second most frequently detected mutation (13/24, 54.16%). No statistical significance was found for any of the epidemiological variables. Due to the problems encountered in a high percentage of samples, the authors concluded that the amplification technique should be improved. The prevalence of resistance detected was around the mean of that found by other authors.

Abstract
We introduce a formalism based on complex unitary vectors for the direction of propagation and for the polarization in order to describe in detail the propagation of inhomogeneous plane waves in absorbing isotropic media. We obtain analytic expressions for the displacement vector, the electric field, the magnetic field, and the Poynting vector, and we study their geometry in terms of the geometrical interpretation of the complex directions of propagation inside the material. We introduce a complex coordinate system based on complex unitary vectors, where the description of the polarization states of the field vectors and the Poynting vector becomes simpler. The physical meaning and the interpretation of the mathematical operations involving these complex unitary vectors is provided.

Abstract
The effects on spontaneous ovulation associated with the unilateral or bilateral sectioning of the superior ovarian nerves (SON) were analyzed in guinea pigs at different time intervals of the estrous cycle. Day 1 of the estrous cycle was defined as the day when the animal presents complete loss of the vaginal membrane (open vagina). Subsequent phases of the cycle were determined by counting the days after Day 1. All animals were autopsied on the fifth day of the estrous cycle after surgery. Sectioning the right, left, or both SONs on day 5 (early luteal phase) resulted in a significant increase in the number of fresh corpora lutea. Ovulation increased significantly when the left SON (L-SON) was sectioned during late follicular phase (day 1) and medium luteal phase (day 8). When surgery was performed on days 1 or 8, neither sectioning the right SON (R-SON) nor sectioning the SON bilaterally had an apparent effect on ovulation rates. Similarly, ovulation rates were not affected when unilateral (right or left) or bilateral sectioning of the SON was performed during late luteal phase two (day 12). Unilateral or bilateral sectioning of the SON performed during the early luteal phase (day 5) was associated with a significant decrease in uterine weight. A comparable effect was observed when the L-SON was sectioned during late follicular phase (day 1), or medium luteal phase (day 8). No effects on uterine weight were observed when unilateral or bilateral sectioning of the SON was performed during late luteal phase. Our results suggest that in the guinea pig the SON modulates ovulation, and that the degree of modulation varies along the estrous cycle. The strongest influence of the SONs on ovulation occurs during early luteal phase, and decrease thereafter, being absent by late luteal phase. In addition, sectioning the left or the right SON caused different responses by the ovaries of adult guinea pigs. This paper discusses the mechanisms by which ovulation increased when the SON was surgically cut.

Abstract
The temporal evolution of the viral load (VL) in a group of patients under clinical care and the identification of individual variables that determined this evolution was studied using a retrospective descriptive study of the VL determinations on 1336 patients between September 1996 and June 2000. During follow-up, patients' VLs increasingly fell below the detection threshold. Those patients who had received antiretroviral treatment prior to the monitoring of the viraemia presented lower VLs at the start of their follow-up. Those patients who had been cared for on the same unit throughout their follow-up maintained lower VLs. Female patients uniformly presented lower VL results than the males. The immunological status at the beginning of follow-up and the basal VL determined the initial evolution of the patients' VL, although it did not do so in the final stages of follow-up. The immunological and virological state at the onset of the follow-up determines the evolution of the patients' VL.
