Abstract
The practice of sports has been steadily evolving, taking advantage of different technological tools to improve different aspects such as individual/collective training, support in match development or enhancement of audience experience. In this work, an in-house implemented monitoring system for golf training and competition is developed, composed of a set of distributed end devices, gateways and routers, connected to a web-based platform for data analysis, extraction and visualization. Extensive wireless channel analysis has been performed, by means of deterministic 3D radio channel estimations and radio frequency measurements, to provide coverage/capacity estimations for the specific use case of golf courses. The monitoring system has been fully designed considering communication as well as energy constraints, including wireless power transfer (WPT) capabilities in order to provide flexible node deployment. System validation has been performed in a real golf course, validating end-to-end connectivity and information handling to improve overall user experience.

Abstract
The aim of this research was to assess the physico-chemical properties and shelf-life of oils press-extracted at two temperatures (60 °C and 80 °C) from five Peruvian castor bean ecotypes. A wide variation for all traits was observed. Low acidity index, low peroxide index and absence of p-anisidine were recorded. The total tocopherol contents ranged from 798 to 1040 mg/kg. A higher antioxidant capacity was detected in methanolic extracts than in hexane extract. From the Rancimat performed at 150-170 °C, the predicted shelf-life at 25 °C ranged from 0.15 to 8.93 years; the higher extraction temperature led to a longer shelf-life, probably because of enzyme inactivation.

Abstract
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. In this context, the notable expansion of new services for smart cities requires, in some specific cases, the construction of underground tunnels in order to enable the maintenance and operation works of utilities, as well as to reduce the visual impact within the city center. One of the main challenges is that, inherently, underground service tunnels lack coverage from exterior wireless communication systems, which can be potentially dangerous for maintenance personnel working within the tunnels. Accordingly, wireless coverage should be deployed within the underground installation in order to guarantee real-time connectivity for safety maintenance, remote surveillance or monitoring operations. In this work, wireless channel characterization for complex urban tunnel environments was analyzed based on the assessment of LoRaWAN and ZigBee technologies operating at 868 MHz. For that purpose, a real urban utility tunnel was modeled and simulated by means of an in-house three-dimensional ray-launching (3D-RL) code. The utility tunnel scenario is a complex and singular environment in terms of radio wave propagation due to the limited dimensions and metallic elements within it, such as service trays, user pathways or handrails, which were considered in the simulations. The simulated 3D-RL algorithm was calibrated and verified with experimental measurements, after which, the simulation and measurement results showed good agreement. Besides, a complete wireless sensor network (WSN) deployment within the tunnels was presented, providing remote cloud data access applications and services, allowing infrastructure security and safety work conditions. The obtained results provided an adequate radio planning approach for the deployment of wireless systems in complex urban utility scenarios, with optimal coverage and enhanced quality of service.

Abstract
AbstractMutations in BRCA1 and BRCA2 high penetrance genes account for most hereditary breast and ovarian cancer, although other new high-moderate penetrance genes included in multigene panels have increased the genetic diagnosis of hereditary breast and ovarian cancer families by 50%. Multigene cancer panels provide new challenges related to increased frequency of variants of uncertain significance, new gene-specific cancer risk assessments, and clinical recommendations for carriers of mutations of new genes. Although clinical criteria for genetic testing continue to be largely based on personal and family history with around a 10% detection rate, broader criteria are being applied with a lower threshold for detecting mutations when there are therapeutic implications for patients with breast or ovarian cancer. In this regard, new models of genetic counselling and testing are being implemented following the registration of PARP inhibitors for individuals who display BRCA mutations. Massive sequencing techniques in tumor tissue is also driving a paradigm shift in genetic testing and potential identification of germline mutations. In this paper, we review the current clinical criteria for genetic testing, as well as surveillance recommendations in healthy carriers, risk reduction surgical options, and new treatment strategies in breast cancer gene-mutated carriers.

Abstract
In this work, the combination of capabilities provided by Wireless Sensor Networks (WSN) with parameter observation in a school garden is employed in order to provide an environment for school garden integration as a complementary educational activity in primary schools. Wireless transceivers with energy harvesting capabilities are employed in order to provide autonomous system operation, combined with an ad-hoc implemented application called MySchoolGardenApp, based on a modular software architecture. The system enables direct parameter observation, data analysis and processing capabilities, which can be employed by students in a cloud based platform. Providing remote data access allows the adaptation of content to specific classroom/homework needs. The proposed monitoring WSN has been deployed in an orchard located in the schoolyard of a primary school, which has been built with EnOcean’s energy harvesting modules, providing an optimized node device as well network layout. For the assessment of the wireless link quality and the deployment of the modules, especially the central module which needs to receive directly the signals of all the sensor modules, simulation results obtained by an in-house developed 3D Ray Launching deterministic method have been used, providing coverage/capacity estimations applicable to the specific school environment case. Preliminary trials with MySchoolGardenApp have been performed, showing the feasibility of the proposed platform as an educational resource in schools, with application in specific natural science course content, development of technological skills and the extension of monitoring capabilities to new context-aware applications.

Abstract
PURPOSE To evaluate the efficacy and safety of oral weekly vinorelbine 60 mg/m2 for metastatic breast cancer (MBC) in patients previously treated with anthracyclines or taxanes in routine clinical practice. MATERIALS AND METHODS Fifty-five patients were enrolled in a prospective multicentre study conducted in Spain. Women ≥ 18 years of age with locally advanced breast cancer who were not candidates for surgical treatment with a radical intention or patients with stage IV disease, and who had received a prior taxane or anthracycline regimen were eligible for participation. RESULTS Median age was 67 years. Median progression-free survival was 3.7 months (95% CI 2.5-4.9), median overall survival 10 months (95% CI 6.6-13.5), and overall response rate and clinical benefit rate were 29.1% and 49.1%, respectively. Main grade 3 and 4 toxicities were neutropenia 9.1%, febrile neutropenia 3.6% and constipation 3.6%. In total, 86% of the patients received complete treatment without delays or dose reduction. Moreover, HER2-positive patients who received oral vinorelbine concomitantly with trastuzumab showed better response (complete response: HER2-positive 14.3% vs. HER2-negative 0%; partial response: HER2-positive 42.9% vs. HER2-negative 25.6%; p = 0.008), better disease control rate (HER2-positive 100% vs. HER2-negative 46.2%; p = 0.011), and better values for the remaining analysed variables than HER2-negative patients. CONCLUSION Our study provides real-world data on the use of oral weekly vinorelbine, which proves an effective and well-tolerated regimen for MBC patients previously treated with taxanes or anthracyclines. Patients with HER2-positive disease could also benefit from this treatment in combination with trastuzumab.

Abstract
Vehicular Ad Hoc Networks (VANETs) are envisaged to be a critical building block of Smart Cities and Intelligent Transportation System (ITS) where applications for pollution, congestion reduction, vehicle mobility improvement, accident prevention and safer roads are some of the VANETs expected benefits towards Intelligent Vehicle Communications. Although there is a significant research effort in Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communication radio channel characterization, the use of a deterministic approach as a complement of theoretical and empirical models is required to understand more accurately the propagation phenomena in urban environments. In this work, a deterministic computational tool based on an in-house 3D Ray-Launching algorithm is used to represent and analyze large-scale and small-scale urban radio propagation phenomena, including vehicle movement effects on each of the multipath components. In addition, network parameters such as throughput, packet loss and jitter, have been obtained by means of a set of experimental measurements for different V2I and V2V links. Results show the impact of factors such as distance, frequency, location of antenna transmitters (TX), obstacles and vehicle speed. These results are useful for radio-planning Wireless Sensor Networks (WSNs) designers and deployment of urban Road Side Units (RSUs).

Abstract
Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modeling focused on vehicle-to-vehicle (V2V), not much work has been done for vehicle-to-infrastructure (V2I) using 3D ray-tracing tools. This work evaluates some important parameters of a V2I wireless channel link such as large-scale path loss and multipath metrics in a typical urban scenario using a deterministic simulation model based on an in-house 3D Ray-Launching (3D-RL) algorithm at 5.9 GHz. Results show the high impact that the spatial distance; link frequency; placement of RSUs; and factors such as roundabout, geometry and relative position of the obstacles have in V2I propagation channel. A detailed spatial path loss characterization of the V2I channel along the streets and avenues is presented. The 3D-RL results show high accuracy when compared with measurements, and represent more reliably the propagation phenomena when compared with analytical path loss models. Performance metrics for a real test scenario implemented with a VANET wireless sensor network implemented ad-hoc are also described. These results constitute a starting point in the design phase of Wireless Sensor Networks (WSNs) radio-planning in the urban V2I deployment in terms of coverage.

Abstract
Abstract
BACKGROUND:
Clinical efficacy and safety of T-DM1 for the treatment of HER2-positive MBC has been assessed in several phase II and III trials and is now considered the standard of care in taxane-and trastuzumab-progressing patients. However, although T-DM1 has shown encouraging antitumor activity in the advanced setting, several strategies to improve T-DM1 efficacy are currently evaluated, including the combination with non-pegylated liposomal doxorubicin (NPLD), considering that: i) doxorubicin is one of the most active chemotherapeutic agents against HER2-positive breast cancer; ii) the combination of doxorubicin and trastuzumab induces synergistic antitumor activity in HER2-overexpressing preclinical models; and iii) liposomal formulations of doxorubicin have a reduced risk of developing cardiac toxicity.
OBJECTIVES:
The primary objective of this trial is to determine the maximum tolerated dose (MTD) of the combination of T-DM1 and NPLD in patients with HER2-positive MBC naïve of anthracyclines and previously treated with trastuzumab and a taxane. The secondary objectives include 1) safety, with special emphasis on cardiac safety evaluated by left ventricular ejection fraction, high-sensitivity troponin I and B-type natriuretic peptide (BNP) levels, 2) pharmacokinetics, 3) antitumor activity, and the 4) role of single nucleotide polymorphisms of HER2 gene for developing cardiotoxicity.
TRIAL DESIGN:
This is a dose-finding, open-label, non-randomized and multicenter phase I clinical trial of T-DM1 at a fixed dose of 3.6 mg/kg IV in combination with three different dose levels (DL) of NPLD (45, 50, and 60 mg/m2) IV administered on Day 1 every three weeks. The trial follows a modified dose escalation scheme with a 3+3 design.A total of three patients will be included in the first cohort and observed for dose-limiting toxicities (DLTs) during the first two cycles of treatment. If none of these patients experiences a DLT, three other patients will be treated at the next DL. However, in case of at least one patient experiences a DLT, three more patients will be treated at the same DL. The MTD will be defined as the highest DL at which ≤1 of six patients experiences a DLT during the first two cycles of treatment. An expansion cohort of six additional patients at the MTD will be included.
ELIGIBILITY:
Anthracycline-naïve patients with HER2-positive MBC and up to two prior chemotherapy regimens in the advanced setting who previously were treated with trastuzumab and a taxane. ECOG performance status of 0-1. Adequate organ and cardiovascular function with LVEF ≥ 55%. RECIST v1.1 evaluable disease.
ACCRUAL:
A total of 12-24 patients will be enrolled at four sites in Spain and France. Recruitment was opened on September 2015. To date, four patients (three at DL1 and one at DL2) have been recruited.

Abstract
The flexibility of new age wireless networks and the variety of sensors to measure a high number of variables, lead to new scenarios where anything can be monitored by small electronic devices, thereby implementing Wireless Sensor Networks (WSN). Thanks to ZigBee, RFID or WiFi networks the precise location of humans or animals as well as some biological parameters can be known in real-time. However, since wireless sensors must be attached to biological tissues and they are highly dispersive, propagation of electromagnetic waves must be studied to deploy an efficient and well-working network. The main goal of this work is to study the influence of wireless channel limitations in the operation of a specific pet monitoring system, validated at physical channel as well as at functional level. In this sense, radio wave propagation produced by ZigBee devices operating at the ISM 2.4 GHz band is studied through an in-house developed 3D Ray Launching simulation tool, in order to analyze coverage/capacity relations for the optimal system selection as well as deployment strategy in terms of number of transceivers and location. Furthermore, a simplified dog model is developed for simulation code, considering not only its morphology but also its dielectric properties. Relevant wireless channel information such as power distribution, power delay profile and delay spread graphs are obtained providing an extensive wireless channel analysis. A functional dog monitoring system is presented, operating over the implemented ZigBee network and providing real time information to Android based devices. The proposed system can be scaled in order to consider different types of domestic pets as well as new user based functionalities.

Abstract
With the growing demand of Intelligent Transportation Systems (ITS) for safer and more efficient transportation, research on and development of such vehicular communication systems have increased considerably in the last years. The use of wireless networks in vehicular environments has grown exponentially. However, it is highly important to analyze radio propagation prior to the deployment of a wireless sensor network in such complex scenarios. In this work, the radio wave characterization for ISM 2.4 GHz and 5 GHz Wireless Sensor Networks (WSNs) deployed taking advantage of the existence of traffic light infrastructure has been assessed. By means of an in-house developed 3D ray launching algorithm, the impact of topology as well as urban morphology of the environment has been analyzed, emulating the realistic operation in the framework of the scenario. The complexity of the scenario, which is an intersection city area with traffic lights, vehicles, people, buildings, vegetation and urban environment, makes necessary the channel characterization with accurate models before the deployment of wireless networks. A measurement campaign has been conducted emulating the interaction of the system, in the vicinity of pedestrians as well as nearby vehicles. A real time interactive application has been developed and tested in order to visualize and monitor traffic as well as pedestrian user location and behavior. Results show that the use of deterministic tools in WSN deployment can aid in providing optimal layouts in terms of coverage, capacity and energy efficiency of the network.

Abstract
One of the main challenges in the implementation and design of context-aware scenarios is the adequate deployment strategy for Wireless Sensor Networks (WSNs), mainly due to the strong dependence of the radiofrequency physical layer with the surrounding media, which can lead to non-optimal network designs. In this work, radioplanning analysis for WSN deployment is proposed by employing a deterministic 3D ray launching technique in order to provide insight into complex wireless channel behavior in context-aware indoor scenarios. The proposed radioplanning procedure is validated with a testbed implemented with a Mobile Ad Hoc Network WSN following a chain configuration, enabling the analysis and assessment of a rich variety of parameters, such as received signal level, signal quality and estimation of power consumption. The adoption of deterministic radio channel techniques allows the design and further deployment of WSNs in heterogeneous wireless scenarios with optimized behavior in terms of coverage, capacity, quality of service and energy consumption.

Abstract
Breast cancer is a burden for western societies, and an increasing one in emerging economies, because of its high incidence and enormous psychological, social, sanitary and economic costs. However, breast cancer is a preventable disease in a significant proportion. Recent developments in the armamentarium of effective drugs for breast cancer prevention (namely exemestane and anastrozole), the new recommendation from the National Institute for Health and Care Excellence to use preventative drugs in women at high risk as well as updated Guidelines from the US Preventive Services Task Force and the American Society of Clinical Oncology should give renewed momentum to the pharmacological prevention of breast cancer. In this article we review recent major developments in the field and examine their ongoing repercussion for breast cancer prevention. As a practical example, the potential impact of preventive measures in Spain is evaluated and a course of practical actions is delineated.

Abstract
A high number of wireless technologies can be found operating in vehicular environments with the aim of offering different services. The dosimetric evaluation of this kind of scenarios must be performed in order to assess their compatibility with current exposure limits. In this work, a dosimetric evaluation inside a conventional car is performed, with the aid of an in-house 3D Ray Launching computational code, which has been compared with measurement results of wireless sensor networks located inside the vehicle. These results can aid in an adequate assessment of human exposure to non-ionizing radiofrequency fields, taking into account the impact of the morphology and the topology of the vehicle for current as well as for future exposure limits.

Abstract
AIM The patterns of impaired internal anal sphincter activity were studied in patients with anal fissure (AF). METHOD Twenty healthy controls and 61 patients with acute AF were studied, using anorectal manometry with electromyography (EMG), and 53 patients with chronic AF using high-resolution manometry and ultrasonography. Mean and maximal resting anal pressure (MRAP), spontaneous rhythmic slow and ultraslow waves (USW) and relaxation induced by rectal distension were measured. RESULTS Patients with acute AF had higher mean (106.4 ± 28.1 mmHg) and maximal resting anal pressure (161.5 ± 43.7 mmHg) than those with chronic AF (P < 0.05); 95% of patients had slow waves (SW) and 67% ultraslow waves. Patients with chronic AF had higher mean (92.4 ± 22.6 mmHg) and maximal resting anal pressure (117.5 ± 32.0 mmHg) than controls and 94% of patients had slow waves and 69% ultraslow waves. Patients with ultraslow waves (with either acute or chronic AF) had increased internal sphincter hypertonicity (mean and maximal resting pressure), decreased internal sphincter relaxation and increased after-contraction following rectal distension. CONCLUSIONS Patients with acute AF had higher hypertonicity than those with chronic AF and both had increased spontaneous rhythmic activity (waves). Patients with AF and ultraslow waves had higher internal anal sphincter hypertonicity and reduced internal sphincter relaxation and enhanced after-contraction following rectal distension.

Abstract
BACKGROUND The efficacy of cognitive stimulation therapy (CST) has been demonstrated, but little is known about the characteristics of people with dementia, which may predict a more positive response to CST. This study sought to investigate which factors may predict response to CST. METHODS Two hundred and seventy-two participants with dementia took part in a 7-week CST intervention. Assessments were carried out pre-treatment and post-treatment. The results were compared with those of a previous comparable CST randomised control trial. A comparison of mean scores pre-CST and post-CST groups was undertaken, and contributing factors that predicted change in outcomes were examined. RESULTS CST improved cognition and quality of life, and the results showed that the benefits of CST were independent of whether people were taking acetylcholinesteraseinhibitor (AChEI) medication. Increasing age was associated with cognitive benefits, as was female gender. Care home residents improved more than community residents on quality of life, but the community sample seemed to benefit more in relation to behaviour problems. CONCLUSIONS These results demonstrate that CST improves cognition and quality of life for people with dementia including those already on AChEIs. Older age and being female were associated with increased cognitive benefits from the intervention. Consideration should be given to aspects of CST, which may enhance the benefits for people with dementia who are male and those younger than 80 years.

Abstract
Kindling is a model in which an initially subconvulsive electrical stimulation of certain brain areas eventually develops a generalized seizure that produces behavioral and long term neuronal changes. In the present study we evaluated if kindling can modify conditioning taste aversion (CTA). In this paradigm animals acquire aversion to saccharin when it is presented as the conditioned stimulus (CS) followed by an injection of lithium chloride (LiCl) that induces a gastric irritation as the unconditioned stimulus (US). Male Wistar rats were implanted with bipolar electrodes aimed at the right amygdala (AMG) or at the right insular cortex (IC). The animals were stimulated daily until they reached stages 2-4 (intermediate) or until kindling was fully established (three consecutive stage 5 seizures). At least two weeks after kindling stimulation had ceased the animals were deprived of water for 24 h and given 10-min drinking sessions twice a day for 4 days. On day 5 (morning session) tap water was replaced by saccharin solution (0.1%), 20 min later the animals were injected with LiCl (7.5 ml/kg i.p., 0.2 M) to induce gastric malaise or taste aversion. After three more days of baseline consumption, water was substituted by a fresh 0.1% saccharin solution to test the aversion. AMG-kindling delayed the extinction of CTA. Animals with kindling in the IC had a higher retention than the sham kindling group; that is, they drank significantly less saccharin solution than the other groups. The results of the present experiment show that local modification of brain function induced by kindling stimulation can prolong the aversive effects of CTA.

Abstract
Acute and late convalescent sera (collected at day 5 of disease onset and 1 year later) from dengue fever (DF) and dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) laboratory confirmed cases, were tested for antibody-dependent cell-mediated cytotoxicity (ADCC) activity using dengue 1 (DENV-1) or dengue 2 (DENV-2) infected cells as target. All patients experienced their first dengue virus (DENV) infection 20 years before. ADCC activity was detected in acute sera from DHF/DSS but not in sera from DF patients. However, 1 year after illness, ADCC activity was observed in all cases. This preliminary report represents one of the few studies of ADCC in dengue patients and suggests that ADCC could be implicated in dengue pathogenesis.

Abstract
10782 Background: Sentinel lymph node is a minimally invasive and accurate staging procedure for patients with invasive breast cancer. Histological SLN involvement with cancer cells requires regional lymph node dissection. Aim: To verify if subgroups of patients with sentinel lymph node involvement in which the risk of histological involvement of additional regional lymph nodes is minimal can be identified. Methods: Ninety six consecutive patients with invasive breast cancer and tumour size less than two centimeters by mammography, had lymphoscintigraphy with colloidal 99Tc and radioisotope-guided sentinel lymph node biopsy in the University Hospital of Zaragoza from 1999 to 2005.Pathological assessment included serial sections of the sentinel lymph node with inmunohistochemistry for cytokeratins in selected cases.39 patients had histological involvement and are presented in this analysis. Results: All 39 patients were females. Median tumour size was 20 mm (range 5–52) Median number of resected sentinel lymph node was 2 (range 1–5) Median number of involved sentinel lymph node was 1 (range 1–4) Regional lymph node dissection was performed in all patients (Axillary dissection in 31; internal mammary dissection in 1, both in 7). Median number of nodes was 13 (range 2–34) At least 1 additional involved lymph node was found in 19 patients (48%) We have correlated patient age, menopausal status, pathological tumour size, histological grade, estrogen receptors, progesterone receptors and Her2 with the risk of histological lymph node involvement in regional lymph node dissection. Conclusions: Tumour size was significantly associated to such risk: No significant financial relationships to disclose.

Abstract
10787 Background: Patients with breast cancer in which sentinel lymph node biopsy is histologically negative for tumor cells, have a low probability of having involvement of additional regional lymph nodes. Lymph node dissection may be avoided in these cases. Methods: Ninety-six consecutive patients with invasive breast cancer and tumour size less than 2 centimeters by mammography, had lymphoscintigraphy with colloidal 99Tc and radioisotope-guided sentinel lymph node biopsy in the University Hospital of Zaragoza from 1999 to 2005.Pathological assessment included serial sections of the sentinel lymph node with immunohistochemistry for cytokeratins in selected cases. Results: Sentinel lymph node biopsy was negative in 57 patients. There were 56 females and 1 male. Median age was 57 years (range 24–87). Median pathological tumor size was 15 mm (range 5–31). Location of the sentinel lymph node was axillary in 47patients, internal mammary in 0 patients, and both in 10 patients. Median number of resected lymph nodes was 2 (range 1–4). With median follow-up of 33 months, no local or systemic relapses have occurred. Conclusions: Avoidance of regional lymph node dissection is safe in patients with breast cancer and histologically negative sentinel lymph node biopsy.

Abstract
20119 Background: The activation of Tyrosin Kinase Receptors (RTKs) produces several effects about cellular response. These are membrane receptors that bind differentiation signals, grow factors and cellular mediators. The interaction with their ligand causes the phosphorilation and internalization in the endosome. By a metabolic way, these receptors are degradated into the proteasome to small peptides that are expressed over the cellular surface joined to MHC class I mollecules, getting a better immunogenic recognition of the tumor cells. It is known that the bigger expression of the tyrosin kinase receptors in tumors is associated with an aggressive phenotype. For example overexpression of ephA2 or EGFR. Our study is based in the demostration of the overexpression of other receptors in renal cell cancer, a tumour with a disappointing response with treatment in advanced stages. On this way we can use them as targets for monoclonal antibodies and for citotoxic lymphocites CD8 stimulated that will join to peptides presented in MHC class I after the proteasomic degradation. Methods: We use Western-Blot for identifying the overexpressed RTKs in relation to normal tissue and as a reference the expression of beta-actin, that is present in every cells. The cells are from 5 murine renal cell cancer lines, (thanks to Hillman Cancer Center Institute, University of Pittsburgh. Pennsylvania. USA). The control is a murine cell line that is very similar to normal renal tissue (HK). We calculate the ratio of expression compared with the expression of normal tissue with an statistical analysis. Results: HER-2, VEGFR-2, Met, Ron-beta are overexpresed in renal cell cancer in a murine model, as EGFR (epidermic growing factor receptor). Conclusions: Met may be excellent therapeutic and inmunologic target and in selected cases of renal cell cancer. It’s known that EGFR and VEGFR are also good targets. Future research about these targets will get new options of combined immunotherapy (vaccines and monoclonal antibodies). No significant financial relationships to disclose.

Abstract
This paper reports the first genetic characterization of Anaplasma (Ehrlichia) platys in Spain from a naturally infected dog. The dog presented clinical signs compatible with canine ehrlichiosis. After DNA extraction and PCR amplification, 16S rRNA gene and citrate synthase gene ( gltA) of this agent were amplified. The GenBank accession number for the nucleotide sequence of the 16S rRNA gene of this strain is AY530806. The A. platys strains registered in France and Japan showed the highest similarity to the 16S rRNA gene sequence obtained from the Spanish strain. In the amplification of the gltA gene, a 1443 bp fragment was obtained, and three nucleotide differences were detected in comparison with other strains sequences. These data confirm the presence of A. platys in a dog showing clinical signs compatible with ehrlichiosis in Spain.

Abstract
AIM To evaluate the energy requirements of breast fed infants. METHODS The study was conducted in 17 healthy exclusively breast fed infants of normal birth weight (mean (SD) 3332 (280) g). Energy expenditure by the doubly labelled water method and milk intake by the dose to infant method were measured at 34 (4) days. A dose of 0. 2 g/kg deuterium oxide (99.8%) and 2.0 g/kg 10% (18)O labelled water was given to the infants, and urine samples were collected for seven consecutive days after dosing. RESULTS The mean (SD) weight of the infants during the period of evaluation was 4617 (343) g and weight gain 34.0 (7.5) g/day. Daily milk intake was 728 (101) g and its metabolisable energy content 2.71 kJ/g. The energy expenditure of the infants was 1205 (312) kJ/day and energy required for growth was 607 (130) kJ/day. When combined this produced an energy requirement of 391 kJ/kg/day for these infants. CONCLUSION These data agree with those from other studies in the United Kingdom and the United States and suggest that adequate growth can be achieved with 19.4% less energy than recommended by FAO/WHO/UNU.

Abstract
The postictal behavioral depression (PBD), characterized by behavioral immobility and unresponsiveness to environmental stimuli, observed after a stage 5 kindling seizure is opioid dependent. Morphine injection prolongs while naloxone and naltrexone (opioid antagonists) reduce or eliminate PBD. Opioids have clear rewarding actions that can be easily detected by place preference conditioning (PPC). In the present study, we evaluated if the opioid release after a stage 5 kindling seizure that produces PBD could induce PPC. Male rats were kindled in the medial preoptic area (MPOA), the amygdala (AMG) or insular cortex (IC). After kindling was established their initial preference in a three-compartment chamber was determined. During conditioning, subjects received a standard kindling stimuli that evoked a stage 5 seizure. At the end of the after discharge and during the PBD the animals were placed in the non-preferred chamber for 30 min. On alternate days they were placed without stimulation in the preferred chamber. At the end of conditioning the kindled groups showed a clear change of preference. This change of preference was completely blocked by injection of naloxone. These results suggest that opioid release after a stage 5 kindling seizure can induce a positive affect of sufficient intensity and duration to induce conditioning.

Abstract
The aim of this study was to generate standard curves for normal spinal and femoral neck bone mineral density (BMD) in Mexican women using dual-energy X-ray absorptiometry (DXA), to analyze geographic differences and to compare these with 'Hispanic' reference data to determine its applicability. This was a cross-sectional study of 4460 urban, clinically normal, Mexican women, aged 20-90 years, from 10 different cities in Mexico (5 in the north, 4 in the center and 1 in the southeast) with densitometry centers. Women with suspected medical conditions or who had used drugs affecting bone metabolism, were excluded. Lumbar spine BMD was significantly higher (1.089 +/- 0.18 g/cm2) in women from the northern part of Mexico, with intermediate values in the center (1.065 +/- 0.17 g/cm2) and lower values (1.013 +/- 0.19 g/cm2) in the southeast (p < 0.0001). Similarly, femoral neck BMD was significantly higher in women from the north (0.895 +/- 0.14 g/cm2), intermediate in the center (0.864 +/- 0.14 g/cm2) and lower (0.844 +/- 0.14 g/cm ) in the southeast part of Mexico (p < 0.0001). Northern Mexican women tend to be taller and heavier than women from the center and, even more, than those from the southeast of Mexico (p < 0.0001). However, these differences in BMD remained significant after adjustment for weight (p < 0.0001). A significant loss (p < 0.0001) in BMD was observed from 40 to 69 years of age at the lumbar spine and up to the eighth decade at the femoral neck. Higher and lower lumbar spine values, as compared with the 'Hispanic' population, were observed in Mexican mestizo women from the northern and southeastern regions, respectively. In conclusion, there are geographic differences in weight and height of Mexican women, and in BMD despite adjustment for weight.

Abstract
BACKGROUND DNA typing in forensic analysis is a useful tool to analyze paternity due to its high discrimination power. AIM To report the experience of Servicio Medico Legal in Santiago, resolving cases of dubious paternity. SUBJECTS AND METHODS Four highly polymorphic loci, amplified by polymerase chain reactions, were analyzed in 153 cases of uncertain paternity. The paternity index was calculated for each case. RESULTS The four genetic markers analyzed provided an exclusion probability of 0.933 for the general population in Santiago. Thirty-seven cases were excluded as parents. In 31 cases, the paternity index ranged from 19 to 100, considered as probable paternity and 77 cases had an index of over 100, considered as almost certain paternity. Eight cases had an index between 0.5 and 19, considered as inconclusive. All loci met Hardy-Weinberg expectations and their frequencies were similar to other data from people living in Santiago. CONCLUSIONS The use of these genetic markers proved to be very useful, reliable and with a high exclusion power for paternity analysis.

Abstract
Genetic marker analysis is a powerful tool for solving paternity-related problems when the putative father is missing. This report describes the first time this approach was employed in Chile to solve such a problem. In the case presented, the alleged father was missing as a result of the political detentions that took place in Chile during 1973. It was not possible to obtain any biological sample from him because he was missing. Thus, the case was resolved by means of genetic marker analysis of the alleged father's close relatives.

Abstract
Incidencia of osteoporosis induced fractures increases with age; risk increases exponentially as bone mass decreases. Women are prone to osteoporosis 2 to 3 times more than men, due to lower "peak" bone mass and the accelerated loss that occurs after the menopause. The prevalence of osteoporosis in with Caucasian postmenopausal women varies from 16 to 30% depending upon the number of sites measured (lumbar spine/hip and/or forearm). The aim of this study was to estimate the prevalence of osteopenia and osteoporosis in pre and postmenopausal Mexican women in relation to men, and to that reported in Caucasia women. The study involved 4,821 apparently healthy subjects (without known risk factors for osteoporosis), 4,467 females and 354 males from 11 different centers of Mexican Republic, 20 to 90 years old, using DXA bone densitometry of lumbar spine and hip. Prevalence of osteoporosis in women is twice that in men (P < 0.001), and it increases with age, particularly after the menopause (P < 0.0001). Our study found a prevalence of osteoporosis of the lumbar spine and/or hip in apparently healthy postmenopausal Mexican women over 50 years of age of 16%, increasing to 20% in those women with or without risk factors who attended voluntarily or by suggestion of their physician to be studied. The prevalence values obtained seem to be lower than those reported for Caucasian women, 30%. We found a prevalence of osteoporosis of 16% and of osteopenia of 57% in women 50 years of age and older. We also found a higher prevalence of osteoporosis in women of the south east part of the county.

Abstract
The analysis of genetic markers in man allows to efficiently resolve cases of dubious paternity. Lately, the use of genetic markers derived from DNA analysis allows high exclusion probabilities. A particular case are those consultations whom the progenitors are closely related, in which the criteria to attribute paternity are modified. The present report explains the analysis methods and interpretation of results in situations of doubtful paternity in cases of incest between father and daughter, using monolocus DNA polymorphisms. The method is illustrated through the analysis of four cases seen at the Servicio Médico Legal of Santiago. To be able to determine paternity in these cases of incest, at least three multiallelic loci in which mother and son have different genotypes must be examined.

Abstract
With the objective of evaluating and accrediting the quality of medical education in the country, the Mexican Association of Medical Schools initiated the National Programme for the Strengthening of the Quality of Medical Education (PNFCE). This programme led to the establishment of the National System of Accreditation. Medical school deans in Mexico determined the criteria for the evaluation of quality and its subsequent standards through a consensus process. The following 10 criteria resulted: general basis and educational objectives; government and institutional orientation; educational programme and academic structure; educational process assessment; students; teaching staff; institutional coherence; resources; clinical sites; and administration. Eighty-eight standards were developed in the instrument designed for the self-evaluation phase. The information resulting from the self-evaluation will be verified by a group of experts during a survey visit, which will be finalized with a report to serve as the basis for the decision to be made by the Accreditation Commission. The self-evaluation phase started in 1994. In 1996 four schools submitted their request for accreditation. As of July 1996, one survey visit has been completed and three more are programmed for the second half of the year.

Abstract
OBJECTIVE To assess the possible impact of smoking on body composition at the 34-39 weeks of pregnancy, and its consequences on birth weight. SUBJECTS 31 smokers and 31 non-smokers matched by age, gestational age and percentage of standard weight (PSW). Smoking mothers had 5 cigarettes or more per day during the whole period of pregnancy and non-smoking mothers never smoked. METHODS A cross-sectional study was conducted in an urban Public Health Center. Anthropometry and the deuterium dilution technique were used to determine body composition. The statistical analysis used a t-test for matched pairs to assess significance of the means difference for each variable. RESULTS Suprailiac and subscapular skinfolds were found to be larger in non-smokers; this difference was significant for the suprailiac skinfold (P < 0.05). No significant difference was found in total body fat, total body water and fat-free mass obtained with the deuterium dilution technique, or FFM determined by anthropometry. Infants' birth weight was similar in the two groups of mothers. CONCLUSION These findings suggest that pregnancy does not modify the pattern of body fat distribution already present in smokers before conception. Infants' birth weight was similar in both groups, probably due to no difference in fat-free mass and body fat. The physiological effect of nicotine (e.g. on prolactin, micronutrients), seems to be clearer during lactation and infant growth.

Abstract
Fresh venom was obtained by milking both sexes of adult Bothrops atrox snakes. Four biological activities were studied in both fresh and freeze dried venom: local hemorrhagic in guinea pig skin, proteolytic upon casein (caseinolytic), esterasic upon TAME and fibrinogen clotting activity. All activities were detected in fresh venom: Hemorrhagic (DHM = 0.93, DHR = 9.75 micrograms protein), caseinolytic (0.25 U kunitz/mg protein), esterasic (0.70 U/mg protein) and clotting activity (75.7 U NIH/mg protein). After freeze drying, all the biological activity of B. atrox venom enzymes decreased: hemorrhagic, caseinolytic and clotting activity in 50% and the esterasic activity only in 15%. Our results show that lyophylization decreases several important biological activities in snake venom related to a decrease in the venom enzymatic activities.
