Abstract:

Purpose Pulque is a fundamental piece in the Mexican gastronomy and identifying consumers’ perception could help promote it and generate new opportunities of commercialization. The purpose of this paper is twofold: first, to explore the underlying factors that influence consumers’ perception toward pulque, and second, to identify groups of consumers according to their perception. Design/methodology/approach A questionnaire was designed and applied to 220 consumers within points of sales. Exploratory factor analysis (EFA) was undertaken and hierarchical cluster analysis (HCA) was used to identify different groups of consumers. Findings By means of EFA three factors were obtained: traditionality, bad reputation of pulquerías and functional beverage. In order to identify different consumption patterns among consumers, HCA was performed and three groups were identified: traditional, neo-consumers and neo-consumers in transition. The groups identified showed significant differences in their perception. Practical implications Pulque has recently gained interest in various consumer sectors, mainly among young consumers, who are consuming and promoting the beverage these days. In this sense, the results of this work could be used for its promotion and consumption in order to attract more consumers and make a contribution to the development of local economies. Originality/value This is the first work in Mexico to explore the perception of consumers toward pulque: the most important traditional fermented beverage in Central México. Results of this research suggest the appearance of a revaluation process among young consumers, more informed and with greater sensitivity toward traditional Mexican food, particularly in the case of pulque. Likewise, these results could be useful for producers and sellers to carry out commercial strategies and promote the drink.

Abstract:

Pulque is a beverage that has been prepared in Mexico since pre-Hispanic times from the fermented sap of more than 30 species of wild and domesticated agaves. We conducted studies in two communities of the state of Michoacán, in central-western Mexico, where we documented its traditional preparation and analyzed the relationship between preparation conditions and the composition and dynamics of microbiological communities, as well as the physical and chemical characteristics of the beverage. In one of the communities, Santiago Undameo (SU), people boil the sap before inoculating it with pulque inoculum; this action causes this local pulque to be sweeter, less acidic, and poorer in bacteria and yeast diversity than in the other community, Tarimbaro (T), where the agave sap is not boiled and where the pulque has more diversity of microorganisms than in SU. Fermentation management, particularly boiling of the agave sap, influences the dynamics and diversity of microbial communities in the beverage.

Abstract:

The aims of this work were to (i) identify the consumers’ profile of pulque through their consumption frequency and their sensory perception of this beverage and (ii) identify the factors that contribute to the valorization of pulque among Mexican consumers. A survey was designed and conducted with 221 consumers in pulque-selling locations (pulquerías) in a place of Central Mexico. Consumers were characterized according to their consumption frequency. Factors associated with the valorization of pulque were identified through Binary Logistic Regression model. Two types of consumers were identified: Frequent Consumers and Not Frequent Consumers. Both groups were comprised mostly of men, including students with medium to high levels of education. However, the first group showed more traditional and conservative behavior patterns since there was a higher proportion of consumers with a low educational level ( p < 0.05) and they had more years of consumption, spend more time in the selling locations, and preferred “natural pulque.” The second group of consumers was comprised mostly ( p < 0.05) of women, including students with a high educational level who prefer “cured pulque.” In this sense, our results showed that gender and time spent in the pulquerías together with sensory, cultural, and functional characteristics associated with the beverage influence its valorization among consumers. These results can help both producers and marketers to classify segments of consumers according to their preferences and consumption patterns in order to revalorize the pulque market. Finally, it is necessary to highlight that young consumers with high educational level show interest in this beverage, since for years its consumption has been associated with low-income populations.

Abstract:

The agaves are plants of cultural importance which have been used by humans for about 10,000 years and about 40 specific uses. The most culturally and economically important of those uses are for the production of fermented (pulque) and distilled beverages (mescal). Pulque continues to be produced in nearly all of Mexico, and the agaves used for this purpose have shown domestication syndrome. We carry out an ethnobotanical, morphological, and genetic analysis of the traditional varieties of pulque agave used in the production of aguamiel (agave sap) and pulque in the state of Hidalgo. We did semi-structured interviews, free listings, and tours with 11 agave managers. We analyzed morphology and studied genetic diversity and structure using nuclear microsatellites. We found wild-collected, tolerated, transplanted, and cultivated varieties of agave. This comprised 19 traditional varieties of pulque agave, 12 of them in production during the study, which corresponded to the species Agave americana, A. salmiana y A. mapisaga and five intraspecific entities. The varieties were grouped morphologically according to a management gradient; the wild-collected varieties were the smallest, with more lateral teeth and a larger terminal spine. The cultivated varieties clearly exhibited domestication syndrome, with larger plants and smaller dentition. The expected heterozygosity (He) of the varieties ranged from 0.204 to 0.721. Bayesian clustering suggested the existence of three genetic groups, both at the level of traditional varieties of pulque agaves and for management categories, a result that matches multivariate clustering. Pulque producers in the studied localities maintain high agrobiodiversity. The cultivated varieties exhibit domestication syndrome, as has been reported for other species of the genus with the same selection purposes. Our results support the hypothesis of a decrease in genetic diversity in crops compared to wild-growing agaves, which seems to be due to vegetative propagation, among other factors.

Abstract:

Pulque is a typical fermented alcoholic beverage of central Mexico, produced from the nectar of maguey agave plants. Production systems are largely artisanal, with inadequate hygiene conditions and exposure to multiple contamination sources. No data exist on pulque microbiological safety and the behavior of pathogenic microorganisms in agave nectar and pulque. An initial trial was done of the behavior of Salmonella Typhimurium, Staphylococcus aureus, Listeria monocytogenes, and Shigella flexneri and Shigella sonnei during fermentation of nectar from a single producer, nectar mixture from different producers, and seed pulque. A second trial simulating artisanal pulque production was done by contaminating fresh nectar with each of the five strains, storing at 22°C for 14 h, adding seed pulque, and fermenting until pulque was formed. During incubation at 16 or 22°C in the first trial, all the pathogenic strains multiplied in both the single producer nectar and the nectar mixture, reaching maximum concentrations at 12 h. Strains concentration then decreased slowly. In the seed pulque, the strains did not multiply and tended to die. In the second trial, all strains increased concentration from 0.7 to 1.6 log at 22°C, and from 0.5 to 1.1 at 16°C in the first 14 h. After addition of seed pulque, they were quickly deactivated until none was detected in the final product. The results suggest that the potential risk to consumers of contracting any of the five tested pathogenic bacterial strains from pulque is low.

Abstract:

The pulque agaves are important cultives in the Valley of Mexico agroecosystems, some management practices have reduction of the sowing density and the farming agave areas. The purpose of this work consisted of knowing the utilization conditions of pulque agaves and evaluate agricultural practices that favor or limit the development of new leaves in Agave salinia.na. Otto ex Salm-Dyck, and Agave mapisaga. Trel., in six localities of the Valley of Mexico, during two sampling years. The results indicate that illegal practice, removing of the cuticle (« mixiote ») affects negatively the development of leaves in agaves, in contrast designated practices: «picado» and «despunte» result beneficial since they do not present meaningful changes on the number of leaves developed with respect to intact plants of the study species.

Abstract:

Currently it is well known that yeasts play an essential role in the production of different beverages. In this paper, were identified some of the yeasts involved in the fermentation process of the pulque, a Mexican traditional beverage. Samples were collected from different regions of Mexico and yeasts were detected directly from samples without cultivation. Identifying the yeasts was obtained using amplification the D1/D2 domain of the 26S rRNA gene and Denaturing Gradient Gel Electrophoresis (DGGE). The results of DGGE showed different profiles of bands in each of the analyzed samples, indicating the presence of several species of yeast, which was also confirmed by sequencing of the bands corresponding to the domain D1/D2, succeeded in identifying five species of yeasts. The results obtained in this work demonstrated that the technique used for identification of yeasts of pulque was efficient. Besides, the optimization of this method could also allow rapid identification of yeasts and help understand the role of these in the fermentation process of this beverage, as well as the isolation of strains of interest for biotechnological purposes such as production of ethanol or metabolites with nutraceutical activity.

Abstract:

AbstractMost representations of Tezcatlipoca, the supreme sorcerer of Late Postclassic central Mexico, come from the codices of the Mixteca-Puebla tradition. This important deity was also represented, however, in statues, wall paintings, bas-reliefs, as well as head-shaped ceramic pieces, the latter of which are little-known and poorly studied. In this study, we offer a detailed analysis of one of the best examples of Tezcatlipoca head-shaped ceramic pieces sheltered in the Bilimek Collection at the Weltmuseum in Vienna. We compare the Tezcatlipoca effigy head of Vienna with similar pieces from the Colección Fundación Televisa in Mexico City, the Museo Regional de Cholula, and the Museo del Valle de Tehuacán, all representations being fine examples of the Eastern Nahua artistic tradition. The similarity between the iconography on the Tezcatlipoca pedestal in Vienna and the murals of Ocotelulco and Tizatlan, Tlaxcala, are particularly striking, sharing representations of skulls, hands, and a motif we have identified as a mirror. We also analyze in detail the links between the iconography of Tezcatlipoca with that of the Macuiltonaleque. Finally, we propose the possibility of a ritual use of these ceramic vessels, associated with the ingestion of pulque in the framework of a Tezcatlipoca drinking cult.

Abstract:

In June of 1739, what might have proven to be a festive early-summer afternoon celebrating the fiesta of Corpus Christi in Pátzcuaro (Mexico), instantaneously veered toward deadly combat when a fight broke out in the streets near a commonly used well in the San Augustín neighborhood, close by where the Corpus procession passed. The turn to violence occurred when two groups of men settled an apparently petty dispute with physical measures that ultimately claimed one participant's life. Two Indian nobles, don Juan de Vargas and his nephew, Santiago Valerio, and a Spaniard, Joseph Ruíz (alias Alvarez), composed one party. Two coyotes, Augustín Calvillo and Matías Martínez Serrillo, and a mulatto, Juan Joseph de los Santos, made up the other. The men knew one and other prior to the argument, though it is impossible to glean from the criminal record of the event whether any festering rivalry played into the dispute. Available evidence suggests that Vargas' refusal to accept a sip of charape (a type of pulque) from Ruíz triggered the incident. This rebuff represented an affront that drew Calvillo, Martínez, and Santos into the fray, siding against the native nobles. In the ensuing upheaval, Valerio sustained a fatal stomach wound.

Abstract:

Abstract Research examining biological risk is critical given that both the Mexican and U.S. populations are aging. Biomarkers can help us understand underlying disease patterns among Mexican-origin individuals in Mexico and the U.S. to help inform disease-prevention efforts for these populations. Using data from the 2012 Mexican Health and Aging Study and the 2010/2012 Health and Retirement Study, we examine seven biomarkers known to predict health risk: systolic and diastolic blood pressure, pulse rate, total cholesterol, HDL cholesterol, glycosylated hemoglobin, and C-reactive protein. Logistic regression models, controlling for age and sex, are used to predict high-risk for each biomarker among Mexico-born Mexicans, Mexico-born Mexican-Americans, and U.S.-born Mexican-Americans. Results show that Mexico-born Mexicans exhibit higher biological risk for systolic blood pressure, pulse rate, low HDL cholesterol, glycosylated hemoglobin, and inflammation than Mexico-born and U.S.-born Mexican-Americans. Additionally accounting for socioeconomic status and health behaviors did not explain differences in high-risk among Mexican-born Mexicans.

Abstract:

During the Pre-Colombian period magueys were used in Mesoamerica for their sap, which is named “aguamiel” (literally “honey water” in Spanish). Aguamiel is then fermented into “pulque”, followed by (in order of importance): textiles, apparel, different thicknesses cords, food (sweetener, syrup, vinegar, flower buds, and cooked immature flowering stalks), firewood and construction materials. The maguey syrup is a product that is traditionally obtained by concentrating the aguamiel by means of an artisanal evaporation treatment (high temperatures, atmospheric pressure and prolonged times). The nutritional and nutraceutical value of this concentrate is unknown despite its wide consumption since pre-Hispanic times in various regions of Mexico. The objective of this work was to evaluate the nutritional value and the content of antioxidant compounds of the maguey syrup obtained from the aguamiel (Agave salmiana and A. mapisaga) through three elaboration treatments (artisanal evaporation, evaporation under reduced pressure and lyophilization). The best species for the production of maguey syrup turned out to be the aguamiel of the A. salmiana due to its nutritional and nutraceutical attributes, higher content of reducing sugars and lower sucrose compared to that of A. mapisaga. The maguey syrup is a sweetener with a higher content of protein (3320 mg 100-1) in comparison to bee honey (152.7 mg 100 g-1). The maguey syrup obtained by lyophilization (LYT) retained the nutraceutical value; but its antioxidant activity was statistically equal to the syrup obtained by evaporation under reduced pressure (RPT), and the artisanal evaporation treatment (AET) had a decrease in vitamin C content in comparison to LYT and RPT. The syrups obtained by RPT and AET presented different degrees of non-enzymatic darkening, possibly due to the formation of melanoidins (dark pigments). The darkest syrup obtained by AET had the highest antioxidant capacity (987.24 μM TE 100 g-1) associated to a higher content of phenolic compounds (593.74 mg GAE 100 g-1).

Abstract:

ntroduction: ‘Perla’ and ‘Mexicano’ are varieties of tuberose grown in Mexico that have potential for commercialization and export; however, no preservative solutions have been evaluated to increase their shelf life. Objective: To determine physical, physiological, and chemical changes that occur in postharvest tuberose when different preservative solutions are applied. Methodology: Tuberose flower spikes of varieties ‘Mexicano’ and Perla, with two open basal flowers, were placed in preservative solutions (Crystal®, sucrose [Sac] + citric acid [CA] + hydroxyquinoline citrate [HQC] and ascorbic acid [AAsc]). A group of tuberose flower spikes was kept as control, and in all cases destructive and non-destructive variables were evaluated during postharvest. Results: Relative fresh weight and water consumption increased with preservative solutions in both varieties. The appearance of the ‘Perla’ variety was excellent for 5 days with Crystal®. The ‘Mexicano’ variety had more open flowers with Crystal® and Sac + AC + HQC, while the ‘Perla’ variety had the same result with AAsc and Crystal®. Respiration in the Mexicano’ variety was high with Sac + AC + HQC, and in the case of ‘Perla’ variety, respiration was low with AAsc. The highest specific superoxide dismutase activity was detected with AAsc and Crystal® for ‘Perla’ variety. Study limitations: The results are valid without previous applications of pulse or hydrating solutions in tuberose varieties evaluated. Originality: This is the first study where the postharvest behavior of two Mexican tuberose varieties is evaluated in preservative solutions. Conclusions: ‘Mexicano’ and ‘Perla’ varieties can use Crystal® and AAsc solutions to maintain the quality for longer time in vase.

Abstract:

Objective:Although several studies suggest that religious involvement tends to favor healthy biological functioning, most of this work has been conducted in the United States. This study explores the association between religious participation and biological functioning in Mexico. Method: The data are drawn from two waves of the Mexican Health and Aging Study (2003-2012) to assess continuous and categorical biomarker specifications. Results: Across specifications, religious participation in 2003 is associated with lower levels of waist-to-hip ratio, total cholesterol, pulse rate, and overall allostatic load in 2012. Respondents who increased their participation over the study period also exhibit a concurrent reduction in pulse rate. Depending on the specification, participation is also associated with lower levels of diastolic blood pressure and C-reactive protein. Participation is generally unrelated to body mass index, glycosylated hemoglobin, and systolic blood pressure. Discussion: Our results confirm that religious participation is associated with healthier biological functioning in Mexico.

Abstract:

A new species of tree cricket, Neoxabea mexicanasp. nov., is described from northeast Mexico. Although it has morphological similarities to two other species found in Mexico, there are distinguishing characters, such as a well-developed tubercle on the pedicel, black markings on the maxillary palpi, one of the two pairs of spots on the female wings positioned at the base of the wings, stridulatory teeth count, and the pulse rate of the male calling song. The calling song description and pre-singing stuttering frequencies are provided. Character comparisons that rule out other species in the genus are presented. The common name given to this new species is Mexican tree cricket. Sound recordings and video are available online. We also make some clarification of the status of Neoxabea formosa (Walker, 1869), described as Oecanthus formosus, and present a key of Neoxabea in North and Central America.

Abstract:

AbstractObjective:Out-of-hospital cardiac arrest is one of the leading causes of death in Mexico, but many survival and prognostic factors are unknown. The aim of this study was to assess out-of-hospital cardiac arrest in a Mexican city.Methods:This was a prospective, cohort study that evaluated the records of the major ambulance services in the city of Queretaro, Mexico. Means, standard deviation, and percentages for the categorical variables were obtained. Logistic regression was performed to determine the effects between interventions, times, and return of spontaneous circulation (ROSC).Results:For an 11-month period, 148 out-of-hospital cardiac arrest cases were recorded. The mean age of the victims was 54 ±22.6 years and 90 (65.3%) were males. Forty-nine cases were related to cardiac disease, 46 to other disease, 27 to trauma, 18 to terminal illnesses, and three to drowning. Twelve (8.6%) patients had a pulse upon hospital arrival, but none survived to discharge. No victims were defibrillated prior to ambulance arrival. The collapse-assessment interval was 22.5 ±19:1 minutes, the mean value for the ambulance response times was 13:6 ±10:4 minutes. Basic emergency medical technicians applied chest compressions to 40 victims (27.2%), controlled the airway in 32 (21.8%), and defibrillated seven (4.8%). Chest compressions and airway control showed an OR of 8 and 12 respectively for ROSC.Conclusions:The poor survival rate in this study emphasizes the need to improve efforts in provider training and public education. Authorities must promote actions to enhance prehospital emergency services capabilities, shorten response times, and provide community education to increase the chances of survival for out-of-hospital cardiac arrest victims in Mexico.

Abstract. During the spring of 2014, 130 million m3 of water were released from the United States' Morelos Dam on the lower Colorado River to Mexico, allowing water to reach the Gulf of California for the first time in 13 years. Our study assessed the effects of water transfer or ecological environmental flows from one nation to another, using remote sensing. Spatial applications for water resource evaluation are important for binational, integrated water resources management and planning for the Colorado River, which includes seven basin states in the US plus two states in Mexico. Our study examined the effects of the historic binational experiment (the Minute 319 agreement) on vegetative response along the riparian corridor. We used 250 m Moderate Resolution Imaging Spectroradiometer (MODIS), Enhanced Vegetation Index (EVI) and 30 m Landsat 8 satellite imagery to track evapotranspiration (ET) and the normalized difference vegetation index (NDVI). Our analysis showed an overall increase in NDVI and evapotranspiration (ET) in the year following the 2014 pulse, which reversed a decline in those metrics since the last major flood in 2000. NDVI and ET levels decreased in 2015, but were still significantly higher (P < 0.001) than pre-pulse (2013) levels. Preliminary findings show that the decline in 2015 persisted into 2016 and 2017. We continue to analyse results for 2018 in comparison to short-term (2013–2018) and long-term (2000–2018) trends. Our results support the conclusion that these environmental flows from the US to Mexico via the Minute 319 “pulse” had a positive, but short-lived (1 year), impact on vegetation growth in the delta.

Desde una perspectiva bourdesiana, se analizan las estrategias de acumulación y conversión de distintas formas de capital (cultural, económico, simbólico y social) que los productores de pulque ponen en práctica en los procesos de construcción social de iniciativas de turismo agroalimentario. Se trata de una nueva actividad rural a la que los productores se incorporan con desventajas materiales y culturales respecto a las reglas del campo turístico consensuadas por los actores dominantes. A partir de un enfoque cualitativo y exploratorio, se estudió la Feria del Pulque en Jiquipilco (Estado de México), en la que se identificó que la apropiación turística del patrimonio agroalimentario se consolida por medio de la reproducción continua de normas, valores y estrategias diferenciados entre los agentes que se disputan los beneficios de la actividad turística.

Abstract:

Abstract Background: Folk medicine plays an important role in some populations in the United States. In particular, the use of rattle snake powder is becoming increasingly popular among the Mexican-American population along the US-Mexico border. Infections associated with the ingestion of this preparation have increasingly been reported in this country. We present a patient who presented with Salmonella Arizonae bacteremia and septic arthritis with underlying ITP on chronic treatment with steroids and surreptitious use of rattle snake powder. Case Report: A 53 year-old Mexican -American male with a past history of ITP on chronic oral prednisone with intact spleen was admitted with fever, chills, and an acute onset of pain, swelling and tenderness of his left knee. On admission to the hospital, his temperature was 101.5 F, blood pressure was 124/68, and pulse 102/min. The physical findings were significant for swelling and tenderness to the left knee with evidence of synovial effusion and restricted range of motion. The white blood cell count was 18,000cu/mm. Culture of the patient’s left knee synovial fluid aspirate grew Salmonella Arizonae, as did his blood cultures. The pathogen was sensitive to 3rd generation cephalosporins and quinolones, and he was treated with intravenous ceftriaxone for 2 weeks with resolution of the bacteremia and improvement of the septic knee. He subsequently underwent a total knee arthroplasty, and follow up 1 year later revealed no evidence of persistent infection. After the pathogen identification, a careful alternative medicine history revealed the consumption of rattle snake powder preparation intended for treatment of his arthritis and ITP. Conclusion: Physicians should be aware of Salmonella Arizonae associated illnesses in both immunocompetent as well as immunosuppressed patients. Because the surge of interest in complementary and alternative medicine, a careful history should be elucidated, especially in immunocompromised patients who present with this syndrome.

AbstractAim:To determine the false-positive rate of pulse oximetry screening at moderate altitude, presumed to be elevated compared with sea level values and assess change in false-positive rate with time.Methods:We retrospectively analysed 3548 infants in the newborn nursery in Albuquerque, New Mexico, (elevation 5400 ft) from July 2012 to October 2013. Universal pulse oximetry screening guidelines were employed after 24 hours of life but before discharge. Newborn babies between 36 and 36 6/7 weeks of gestation, weighing >2 kg and babies >37 weeks weighing >1.7 kg were included in the study. Log-binomial regression was used to assess change in the probability of false positives over time.Results:Of the 3548 patients analysed, there was one true positive with a posteriorly-malaligned ventricular septal defect and an interrupted aortic arch. Of the 93 false positives, the mean pre- and post-ductal saturations were lower, 92 and 90%, respectively. The false-positive rate before April 2013 was 3.5% and after April 2013, decreased to 1.5%. There was a significant decrease in false-positive rate (p = 0.003, slope coefficient = −0.082, standard error of coefficient = 0.023) with the relative risk of a false positive decreasing at 0.92 (95% CI 0.88–0.97) per month.Conclusion:This is the first study in Albuquerque, New Mexico, reporting a high false-positive rate of 1.5% at moderate altitude at the end of the study in comparison to the false-positive rate of 0.035% at sea level. Implementation of the nationally recommended universal pulse oximetry screening was associated with a high false-positive rate in the initial period, thought to be from the combination of both learning curve and altitude. After the initial decline, it remained steadily elevated above sea level, indicating the dominant effect of moderate altitude.

Abstract:

In Mexico, CHD incidence is estimated at 18,000-21,000 newborns per year, and at least 25% will have critical congenital heart disease (CCHD). The mortality rates showed that 24% of the infant deaths in 2013 were attributable to CCHDs. Despite these, the CCHD screening is not performed in all hospitals. The general objective is to show the statistical relationships, compared with existing evidence of the power of repeat screenings on detection of CCHD, to better inform government recommendations for universal screening in Mexico. Three thousand seven pulse oximetry readings were performed on newborns (the 5th of February - the 1st of July of 2019). We aimed to perform the first screen on the subjects between 5-48 hrs of life. Some required a repeat reading due to a failure in the first. Screenings occurred between 6-69 hrs, with a mean time of 22 hrs post-delivery. Secondary readings were performed on 160, of which 29 were also given echocardiograms because they failed the secondary test. The average measurement on the foot was 93.8% and on the right hand was 93.5%. In the 29 subjects with repeated readings, seven were positive for CCHD; two were false positives. The data and analysis show promise in the association between early readings and the detection of potential CCHD. There is a correlation between the concerning readings and detection of CCHD through an echocardiogram. More data is needed to ascertain other relationships, but the results thus far imply low pulse oximetry readings associated with CCHDs and other secondary conditions associated with hypoxemia.

Abstract:

In this article, a technique for the reduction of total harmonic distortion (THD) in distributed renewables energy access (DREA) composed of wind turbines is introduced and tested under the wind speed conditions presented in Tamaulipas, Mexico. The analysis and simulation are delimited by a study case based on wind speeds measured and recorded for one year at two highs in the municipality of Soto La Marina, Tamaulipas, Mexico. From this information, the most probable wind speed and the corresponding turbulence intensity is calculated and applied to a wind energy conversion system (WECS). The WECS is composed of an active front-end (AFE) converter topology using four voltage source converters (VSCs) connected in parallel with a different phase shift angle at the digital sinusoidal pulse width modulation (DSPWM) signals of each VSC. The WECS is formed by the connection of five type-4 wind turbines (WTs). The effectiveness and robustness of the DREA integration are reviewed in the light of a complete mathematical model and corroborated by the simulation results in Matlab-Simulink®. The results evidence a reduction of the THD in grid currents up to four times and which enables the delivery of a power capacity of 10 MVA in the Tamaulipas AC distribution grid that complies with grid code of harmonic distortion production.

Abstract:

Repetitions of precise spike patterns observed both in vivo and in vitro have been reported for more than a decade. Studies on the spike volley (a pulse packet) propagating through a homogeneous feedforward network have demonstrated its capability of generating spike patterns with millisecond fidelity. This model is called the synfire chain and suggests a possible mechanism for generating repeated spike patterns (RSPs). The propagation speed of the pulse packet determines the temporal property of RSPs. However, the relationship between propagation speed and network structure is not well understood. We studied a feedforward network with Mexican-hat connectivity by using the leaky integrate-and-fire neuron model and analyzed the network dynamics with the Fokker-Planck equation. We examined the effect of the spatial pattern of pulse packets on RSPs in the network with multistability. Pulse packets can take spatially uniform or localized shapes in a multistable regime, and they propagate with different speeds. These distinct pulse packets generate RSPs with different timescales, but the order of spikes and the ratios between interspike intervals are preserved. This result indicates that the RSPs can be transformed into the same template pattern through the expanding or contracting operation of the timescale.

Abstract. We conducted high frequency measurements of the δ18O value of atmospheric CO2 from a juniper (Juniperus monosperma) woodland in New Mexico, USA, over a four-year period to investigate climatic and physiological regulation of the δ18O value of ecosystem respiration (δR). Rain pulses reset δR with the dominant water source isotope composition, followed by progressive enrichment of δR. Transpiration (ET) was significantly related to post-pulse δR enrichment because the leaf water δ18O value showed strong enrichment with increasing vapor pressure deficit that occurs following rain. Post-pulse δR enrichment was correlated with both ET and the ratio of ET to soil evaporation (ET/ES). In contrast, the soil water δ18O value was relatively stable and δR enrichment was not correlated with ES. Model simulations captured the large post-pulse δR enrichments only when the offset between xylem and leaf water δ18O value was modeled explicitly and when a gross flux model for CO2 retro-diffusion was included. Drought impacts δR through the balance between evaporative demand, which enriches δR, and low soil moisture availability, which attenuates δR enrichment through reduced ET. The net result, observed throughout all four years of our study, was a negative correlation of post-precipitation δR enrichment with increasing drought.

Abstract:

Denis Jourdanet (1815–1892) was a French physician who spent many years in Mexico studying the effects of high altitude. He was a major benefactor of Paul Bert (1833–1886), who is often called the father of high-altitude physiology because his book La pression barométrique was the first clear statement that the harmful effects of high altitude are caused by the low partial pressure of oxygen. However, Bert's writings make it clear that the first recognition of the critical role of hypoxia at high altitude should be credited to Jourdanet. Jourdanet noted that some of his patients at high altitude had features that are typical of anemia at sea level, including rapid pulse, dizziness, and occasional fainting spells. These symptoms were correctly attributed to the low oxygen level in the blood and he coined the terms “anoxyhémie” and “anémie barométrique” to draw a parallel between the effects of high altitude on the one hand and anemia at sea level on the other. He also studied the relations between barometric pressure and altitude, and the characteristics of the native populations in Mexico at different altitudes. Jourdanet believed that patients with various diseases including pulmonary tuberculosis were improved if they went to altitudes above 2,000 m. This led him to recommend “aérothérapie” in which these patients were treated in low-pressure chambers. Little has been written about Jourdanet, and his work deserves to be better known.

Abstract:

P125 Pulse pressure, a measure of aortic stiffness, has recently been shown to be a strong predictor of cardiovascular mortality in both normotensives and hypertensives. It is also an important predictor of left ventricular hypertrophy. Unfortunately, little is known about the genetic etiology of pulse pressure. To address this problem we performed genetic analysis on 46 randomly ascertained families (1306 individuals) in the San Antonio Family Heart Study. Pulse pressure (PP) was defined as the difference between systolic and diastolic blood pressure. Likelihood methods were used to construct a model that had both single-locus and polygenic components. The single-locus component included sex-specific and genotype-specific effects of both age and body mass index (BMI). Using this model we then performed two-point linkage analysis of 10 large families (440 individuals), which were a randomly chosen subset of the initial 46 families, that have been genotyped for 396 polymorphic markers. Results showed that when the model contained only the polygenic component and simple effects of the covariates then the heritability of PP is .21. Adding the single-locus component was highly significant (p<.0001). In addition, within the single-locus component, the sex-specific and genotype-specific effects of age and BMI were also highly significant (p<.002). This full model accounted for 73% of the total variation of PP. Linkage analysis of this model with each marker showed four markers with lodscores > 1.9, which is the Lander-Kruglyak standard for suggestive linkage. D21S1439 had a lodscore of 2.78 with a recombination fraction (θ) of 0.02. D7S1799 had a lodscore of 2.04 (θ=0.01). D8S1100 had a lodscore of 1.98 (θ=0.08) and D18S844 had a lodscore of 1.95 (θ=0.11). We conjecture that pulse pressure is affected by several major genes and that together these genes account for the highly significant genotype-specific single-locus effect observed here.

Abstract:

Screening for critical congenital heart disease is a clinical method used for their early detection using pulse oximetry technology. This, followed by a diagnostic confirmatory protocol, allows timely therapeutic interventions that improve the newborn’s outcome. According to Mexican birth statistics, approximately 18,000–21,000 neonates are born with a form of congenital heart disease each year, of which 25% are estimated to be critical congenital heart disease. We report two cases with an early critical congenital heart disease detection and intervention through an innovative critical congenital heart disease screening program implemented in two Mexican hospitals. They integrated a new automated pulse oximetry data analysis method and a comprehensive follow-up system (Cárdi-k®). Both cases were confirmed by echocardiogram, which served for an intervention in the first week of life, and the patients were discharged in good clinical condition. In addition, to the routine physical assessments, the critical congenital heart disease screening program (which includes echocardiogram for presumptive positive cases) should be implemented in a timely manner.

Abstract:

Presented is the project called MAMICare, which is motivated by the alarming number of maternity and infant deaths in rural areas due mainly to a poor monitoring of pregnancy progress and lack of appropriate alerting mechanism in case of abnormal gestation evolution. This work proposes an information technology solution based on mobile devices, and health sensors such as ECG (electrocardiogram), stethoscope, pulse-oximeter, and blood-glucose meter to collect automatically relevant health data for a better monitoring of pregnant women. This article addresses the status of the maternity infant death problem especially in rural areas of Mexico. It reviews some applications of IT in health systems (known also as Electronic Health or simply e-Health) and discusses how these are related to the presented proposal and how they differ. The article presents the proposed solution and discuss the current status of the work.

Abstract:

Many bromeliad species indigenous to the rain forests of Central and South America are threatened because of over-collection and habitat destruction. Studies were conducted to develop propagation protocols for Tillandsia eizii, a rare ornamental bromeliad of ceremonial significance to the Highland Maya communities in Chiapas, Mexico. We anticipate using in vitro propagation for the conservation of this species with the potential of utilizing bromeliads as an alternative and sustainable forest resource. Protocols were developed for the sterilization and germination of axenic seed. Seedling growth in vitro was assessed and outplanting studies were conducted. Media were evaluated to promote adventitious bud production in experiments using the plant growth regulators naphthaleneacetic acid and benzylaminopurine. Pulse time and duration, as well as the stage of seed development, had a marked effect on bud production. The effects of various potting media on plant growth and survival were assessed. A pure pine bark medium elicited over 95 percent survival. Plants exhibited a “tank-like” morphology characteristic of plants in the wild.

Here we examine how lagomorph (rabbit and hare) deposition rate, population age structure and taxonomic composition from Abrigo de los Escorpiones, a well-dated, trans-Holocene vertebrate fauna from northern Baja California, Mexico, vary as a function of the frequency of wet El Niño events and eastern Pacific sea-surface temperatures (SSTs) derived from eastern Pacific geological records. Faunal indices vary significantly in response to El Niño-based precipitation and SST, with substantial moisture-driven variability in the middle and late Holocene. The late Holocene moisture pulse is coincident with previously documented changes in the population dynamics of other vertebrates, including humans. As the frequency and intensity of ENSO is anticipated to vary in the future, these results have important implications for change in future vertebrate populations.

Abstract:

This case describes a patient presenting with acute onset papilledema, subacute strokes resulting in upper extremity weakness and numbness, arthritis, maculopapular rash, depressed C4 and CH50, and a high titer anti-double-stranded DNA antibody. The patient was given the diagnosis of probable systemic lupus erythematosus, which was supported by the Systemic Lupus International Collaborating Clinics (SLICC) criteria. He was aggressively treated for neuropsychiatric lupus (NPSLE) with pulse dose steroids and a dose of intravenous cyclophosphamide. Blood cultures drawn on admission later grew out 2/4 bottles of Gram-variable bacteria, speciated as Brucella melitensis by PCR. Serum Brucella serologies were also positive. On further evaluation, the patient noted a history of eating unpasteurized cheese in Mexico. Given these additional findings, the patient’s presentation was most consistent with a diagnosis of neurobrucellosis. Steroids were tapered off, no further doses of cyclophosphamide were given, and a prolonged course of intravenous and oral antibiotic therapy was administered, resulting in complete resolution of the patient’s presenting symptoms.
