Background The use of health services by the adult population is related to cardiovascular risk and its stratification. Cardiovascular risk (CVR) stratification should be a tool for the assessment of the patients and the appropriate control during the process of medical care and utilization of health services for the adults. Objective Evaluate the association between cardiovascular risk (CVR) in adults and the utilization of health services. Material and Methods A secondary analysis was performed of the data from the National Health and Nutrition Survey (ENSANUT) 2018-2019. The CVR classification (risk score) was obtained in 43,070 adults with a previous diagnosis (self-report) and 1,237 adults newly diagnosed. Independent, risk factors and the association between groups of CVR and utilization of preventive, outpatient and hospital services were analyzed. Results More than 85% of adults interviewed have some degree of CVR. Almost half of them have low CVR (48.2%). Older adults with social security predominate in the group with high and very high CVR. Seventy-five percent of adults recently diagnosed have low CVR. In both, there is very little utilization of health services. For adults previously diagnosed CVR, the higher the CVR, the greater the likelihood of utilization of outpatient, preventive and hospital services, in contrast to adults without CVR independent of the marital status, sex, health institution and socioeconomic level. Conclusion The results give evidence of areas of opportunity for improvement in the quality of health services. The evaluation of CVR in primary care and promotion and prevention of CVR should be strengthened.

Traditional mining activities are usually correlated with high levels of soil pollution, which is a major environmental concern. Extensive mining activities have taken place in the San Joaquin region in the State of Querétaro, México resulting in high levels of mercury soil pollution (up to 1532 ± 300 mg/kg). We isolated mercury-resistant fungal strains from the San Joaquin region soils and identified them through morphologic characteristics and ITS rDNA region sequence analysis. We determined that fungi isolated belong to the genus Trichoderma. All the isolates selected showed the ability to catalyze the volatilization of Hg. For air sampling, an active sampling device was constructed and using acid KMnO4 as an absorbent, the concentration of mercury in solution was determined through the cold vapor atomic absorption method. The results show mercury volatilization from the fungal species assay, with a maximum of 213.04 ± 32.6 μg/m3 while mycelium accumulation ranged from less than 17.5 ± 2.9 to 20.0 ± 3.4 μg/g. The fungal isolates were also evaluated for their ability to reduce mercury uptake in Arabidopsis thaliana. These observations suggest the utility of Trichoderma for the mobilization of mercury in those contaminated soils.

The 1-（3-methoxycarbonyl） propyl-1-phenyl-（6,6）C61 （also called PCBM） is a C60 derivative widely used as an electron-acceptor in organic solar cells. To date, all the infrared spectra reported are experimental, mainly because of the calculations needed to study these structures are highly time-consuming. In this report we address for the first time the infrared spectrum calculation of PCBM with Cs symmetry by using the PW91/dnp level as implemented in the Dmol3 code. In this calculation we have found two intense peaks in the IR spectrum, that agree fairly with the 1187 and 1787 cm^-1 measured experimentally.

Single incision laparoscopic surgery(SILS) is a minimally invasive platform with specific benefits over traditional multiport laparoscopic surgery. The safety and feasibility of SILS has been proven, and the applications continue to grow with experience. After 500 cases at a high-volume, single-institution, we were able to standardize instrumentation and operative steps, as well as develop adaptations in technique to help overcome technical and ergonomic challenges. These technical adaptations have allowed the successful application of SILS to technically difficult patient populations, such as pelvic cases, inflammatory bowel disease cases, and high body mass index patients. This review is a frame of reference for the application and wider integration of the single incision laparoscopic platform in colorectal surgery.

World Journal of Neuroscience 2014年第3期4卷 253-260页

The development of excessive and persistent drinking under intermittent food-reinforcement schedules, known Schedule-induced polydipsia (SIP), has been proposed as a successful animal model to study compulsive behaviors. On the last decade, we have been working in our laboratory on the stratification of the compulsive rats on SIP in order to know whether differences in the acquisition of compulsive drinking behavior could predict alterations in other behavioral measures as well as in the neurochemical function typically associated with compulsive spectrum disorders. The aim of this review is to collate the main findings relevant to the characterization and use of the high compulsive drinking rats (HD) in SIP as a possible compulsive endophenotype. The review of the genetic, behavioral and neurochemical differences found in the selection allows us to conclude that HD rats could be a valid model for studying the compulsive phenotype and modelling psychopathology common to a variety of compulsivity spectrum disorders such as obsessivecompulsive disorder (OCD), schizophrenia and alcohol abuse.

Marine Priority Region No. 33 (MPR 33) lies in the State of Guerrero, where the National Commission for Knowledge and Use of Biodiversity has declared a lack of information on marine species, Class POLYPLACOPHORA among others. This program was carried out on the rocky intertidal zone of MPR 33 with the objectives to: 1) determine species richness, 2) community composition based on families represented, 3) estimate the density, 4) index of diversity, 5) analyze body proportions and 6) geographic distribution of species. Three surveys on five sites were conducted during 2009 and 2012, using one mt2 quadrant for systematic sampling procedure;collecting all POLYPLACOPHORA specimens found within the quadrants, then proceeding with their preservation. 441 organisms were analyzed where 17 species were identified, on nine genera within six families. Fifteen new species were recorded for the MPR 33. Family ISCHNOCHITONIDAE Dall, 1889 was the best represented in species richness and CHITONIDAE Rafinesque, 1815 in abundance. Density of 8.82 organisms/m2, the H′ index was 2.38 bits/individuals and J′ = 0.57. The species Chiton (Chiton) articulatus Sowerby, 1832 showed the highest density, greater size and was found in all five collection sites. Three species, (Chiton (C.) articulatus, Ischnochiton (Ischnochiton) muscarius (Reeve, 1847) and Chiton (Chiton) alboli-neatus Broderip & Sowerby, 1829), were considered wide. Intertidal species richness was associated with habitat stability and wave intensity;the more unstable sites had greater richness while most stable sites lower. Species inventory and understanding the communities’ interactions of the marine fauna of the State of Guerrero are important;therefore these efforts must be continued.

An important part of the fishing activity in Mexico is carried out in the coastal strip and has a strong social, economic and ecological importance. In the state of Guerrero, mollusks fishing is coastal and craftwork activity focused on a small number of species and without information on biology and reproductive or ecological aspects for most species caught. This research was carried out in the Costa Chica region, Guerrero, Mexico and the aims were: 1) To analyze the socioeconomic features of cooperative societies of fishing production;and 2) To know the diversity of mollusks caught by coastal fishing and the species that have the greatest importance in fishing. From February to April 2013-2015, seven fish coop units, four piers and places where seafood is sold were visited. For the socio-economic analysis and the determination of the species that have more importance in the coastal fishing, a total of 67 surveys were applied. In order to determine the cast of species, the specimens captured by the fishermen were used, which were identified and counted. A total of 67 interviews were analyzed and an average of $1806.00 was estimated as weekly economic income just as a product of fishing, it was also estimated that on average the fishermen work 4.3 days a week. Fisheries cooperatives market most of their produce directly to restaurateurs and locals on the piers. Replacement of older adults by young fishermen from the same region was observed, most are adults between 22 and 39 years old. 25 species of mollusks of economic importance were registered for the coastal fishermen of the Costa Chica. Six species were identified as the main target for catching fishermen. The fishing of mollusks in Costa Chica is not subject to any type of control, which has led to overfishing reflected in the decline sizes and banks in populations of commercial importance.
