Cervical cancer is a priority health problem in Mexico. The objective of this work was to know the degree of satisfaction of the service provider with the organization of the program of Timely Detection of Cervical Cancer, specifically in taking of the cervical cytology. The study design was observational, transversal and prospective conducted from January to May 2015 in Jurisdiction 1 of the Health Services of San Luis Potosí, Mexico, in 20 health centers. Participants were 87 service providers whose function is to take cervical cytology (Pap smears). A 32-question questionnaire was applied, with Likert scale with 5 levels of response: 1 (dissatisfied), 2 (little satisfied), 3 (indifferent), 4 (satisfied) and 5 (very satisfied). The score range was 32 points (minimum job satisfaction) up to 160 points (Maximum job satisfaction). We analyzed 2 dimensions: 1) intrinsic factors that have to do with motivation and professional recognition, and 2) extrinsic factors related to infrastructure, materials, remuneration and labor policies. Each factor consisted of four categories. Descriptive statistics and linear correlation of Pearson were applied for the analysis of data. Participants signed an informed consent letter. Of 4 categories, in the intrinsic dimension, the one with the highest percentage of satisfaction was “delegation of activities” with 28.8%. In the extrinsic dimension, the category with the highest percentage of satisfaction was “infrastructure and materials” with 49.4%;while satisfaction increase in intrinsic dimensions also does in extrinsic dimensions, such correlations are significant (p < 0.05), except between delegation of activities and remuneration (r = 0.074 and p = 0.497). The higher hierarchical level, the men, the bachelor academic level and older people showed the highest level of satisfaction.

Arsenic Removal from Zimapan Contaminated Water Monitored by the Tyndall Effect

In Zimapan Valley, Mexico, up to 1.1 mg·L-1 of arsenic concentrations have been detected in deep wells that are used as drinking water supply for almost 39,000 people, which could have been exposed to levels higher than 10 μg·L-1 of arsenic, the maximum level recommended by the World Health Organization. Chronic consumption of water contaminated with arsenic can cause several diseases, including cancer. For it, the implementation of practical and economical methods to remove arsenic from drinking water is crucial to protect the population health. In this work, an electrochemical method to remove arsenic from drinking water is described. The process, monitored by Tyndall effect, utilizes Cu2+ and Zn2+ ions from a brass electrode in an electrochemical cell with water as electrolyte. Results show that the EC process reduces the concentration of the arsenic diluted in Zimapan water to a level below the limit of detection of the atomic absorption spectrophotometer employed. Arsenic was removed through the formation of Cu and Zn arsenic compounds. Cu2+ and Zn2+ ions form a hydroxide and eventually polycrystalline precipitation of kottigite and cornubite complexes (identified by energy-dispersive X-ray spectroscopy and X-ray diffraction), which are then filtered to eliminate the precipitated arsenic compounds.

Variability of the optical properties of the northern Gulf of California (México) were analyzed for the first time based on six cruises performed from spring to summer (March to September) between 2008 and 2013. The changes observed in the absorption by three seawater components (phytoplankton, detritus and chromophoric dissolved organic matter or CDOM) were analyzed in relation to changes in bio-optical regions and composition of the phytoplankton community (determined based on phytoplankton pigments). Two regions with unique bio-optical characteristics were identified separated by a narrow transition zone: the Upper Gulf of California (UGC) and Northern Gulf of California (NGC). Despite the temporal changes in their spatial distribution they maintained particular characteristic. UGC is characterized by an average Chla of 1.78 mg/m3, the dominance of microphytoplankton (diatoms and dinoflagellates) and a stronger contribution of detritus to total light absorption. NGC is characterized by an average Chla of 0.7 mg/m3 and the predominance of picophytoplankton, characterized by the dominance of zeaxanthin (marker pigment for cyanobacteria) and/or chlorophyll b (marker pigment for green algae), along with a co-dominium by CDOM and phytoplankton to light absorption. Results indicate that Case II waters can be very different when evaluating the individual contribution by phytoplankton, detritus and CDOM to total light absorption what has to be considered for the selection of bio-optical models for each specific region what can also help to a better definition of the related uncertainties.

In the last two decades, unprecedented changes have taken place in the frequency and severity of wildfires;in different regions of the world, some fires were even classified as megafires. Although there are studies about the diverse effects of fire, which have made significant theoretical contributions, a comprehensive review of the changes in fire research is required to understand worldwide patterns, particularly in those countries where fire activity is on the rise, such is the case of Mexico. The objective of this study was to analyze the trends in the research on wildfires published in Mexico and worldwide over a 40-year timescale. For this purpose, the Web of Science database, bibliometric tools, and the keywords TI = Forest fire* OR TI = Wildfire* were used to extract as many articles as possible related to fires from 1980 to 2020, without being restricted to those studies whose title included any of the variants of the keywords. There were 8458 publications about fires in the vegetation cover, with a notable increase in the frequency of studies in the previous decade;52% of the studies were concentrated in five countries and 20% of the articles focused on the study of different aspects of the soil. Mexico ranks thirteenth in volume of scientific production and studies in the country have focused mainly on the description of the quantitative relationship between the size of the affected area and the number of occurrences in the landscape, meanwhile, studies on fires and the consequences on the biotic interactions have been little explored.

Heart diseases are the main cause of mortality in Mexico, being coronary heart disease the most frequent in the country. Its high prevalence makes important the study of the pathophysiology and the search for prognostic factors. Different genes and polymorphisms promote atherogenesis and coronary artery disease, they affect inflammatory and vascular pathological processes. Interferon regulatory factor 5 (IRF5) is associated with coronary heart disease, it promotes chronic inflammation and cytokines release;it could trigger immune reactions and its activating receptors express in the vascular endothelium. Besides, polymorphisms in the renin-angiotensin-aldosterone system (RAAS) are implied with coronary disease, they are found in angiotensinogen (AGT), angiotensin II type 1 receptor (AT1R), angiotensin II type 2 receptor (AT2R), and angiotensin-converting enzyme (ACE) genes. These genetic polymorphisms are associated with a prothrombotic state, endothelial dysfunction, and immune activation. Multiple experimental studies showed that chronic activation of RAAS and chronic expression of IRF5 generates an environment prone to the development of atherosclerosis, and autoimmune and cardiovascular diseases. Studying these specific genes and their relationship with coronary heart disease will allow a better understanding of the pathological process and possibly the quest for new treatments.

本文旨在研究一种用于评估电影对观影者脑活动影响的新方法。当观影者在自由观影时,利用功能性核磁共振成像(f MRI)测量观影者的脑活动数据,并结合被试者相关性分析(ISC)来评估在观看影片时观影者之间大脑在时空反应上的相似性。研究结果表明,某些影片对观影者脑活动及眼运动显示出显著的控制。但是,电影剧情、剪辑手段及导演风格的不同对观影者脑活动和眼运动产生的影响也不尽相同,所以这一结论无法推广至所有电影。如果能将不同类型的影片对观影者大脑的影响进行神经科学上的定量评估,那么ISC就可以对电影学研究有所帮助,成为电影产业更好地评估电影作品的有效方法。同时,这一方法将两个毫无关联的学科——认知神经科学和电影学结合在一起,开启了一个新的跨学科研究领域——神经电影学。
