| 2 | Land cover change and carbon stores in a tropical montane cloud forest in the Sierra Madre Oriental,Mexico显示文摘Tropical montane cloud forest is one of the ecosystems with the highest biomass worldwide, representing an important carbon store. Globally its deforestation index is –1.1%, but in Mexico it is higher than –3%. Carbon estimates are scarce globally, particularly in Mexico. The objective of this study was to simulate future land-cover scenarios for the Sierra Madre Oriental in Mexico, by analyzing past forest cover changes. Another objective was to estimate stored carbon in the two study areas. These objectives involve the generation of information that could be useful inputs to anti-deforestation public policy such as the REDD+ strategy. Remote sensing was used to measure land cover change and estimate carbon stocks. Satellite images from 2015, 2000 and 1986 were used, and Dinamica EGO freeware generatedmodels of future projections. Between 1986 and 2015, 5171 ha of forest were converted to pasture. The annual deforestation rates were –1.5% for Tlanchinol and –1.3% for the San Bartolo Tutotepec sites. Distance to roads and marginalization were highly correlated with deforestation. By 2030, an estimated 3608 ha of forest in these sites will have been converted to pasture. Stored carbon was estimated at 16.35 Mg C ha-1 for the Tlanchinol site and 12.7 Mg C ha-1 for the San Bartolo site. In the Sierra Madre Oriental deforestation due to land cover change(–1.4%) is higher than levels reported worldwide. Besides having high values of stored carbon(14.5 Mg C ha-1), these forests have high biodiversity. The models' outputs show that the deforestation process will continue if action is not taken to avoid the expansion of livestock pasturing. This can be done by paying incentives for forest conservation to the owners of the land. The results suggest that REDD+ is currently the most viable strategy for reducing deforestation rates in tropical montane cloud forests in Sierra Madre Oriental. | Edgar G.LEIJA-LOREDO Numa P.PAVóN Arturo SáNCHEZ-GONZáLEZ Rodrigo RODRIGUEZ-LAGUNA GregorioáNGELES-PéREZ | 2018 | Journal of Mountain Science2018，15，10： | 2 |
| 3 | Technical problems produced by the Bravo pH test in nonerosive reflux disease patients显示文摘AIM: To evaluate the technical failures of the Bravo pH test in a population with nonerosive gastroesophageal reflux disease. METHODS: Over the course of a year, we prospectively studied a population of 66 nonerosive reflux disease patients who received a Bravo pH test. The number and frequency of all technical failures were documented, quantified and analyzed. RESULTS: A total of 66 patients, with a mean age of 41.7 years, were studied. Technical failures occurred in 15.15% of the sample. The most frequent failures were due to poor data reception (4.5%), early dislodgement (4.5%) and capsule removal (6.1%). CONCLUSION: The Bravo capsule pH test involves a low but non-negligible rate of technical problems, a fact that must always be considered by physicians. | Andrés de Hoyos Edgar Alain Esparza | 2010 | World Journal of Gastroenterology2010，16，25： | 2 |
| 4 | Determination of functional fitness age in women aged 50 and older显示文摘Background: The construction of useful and attainable indicators of fitness assessment deserves special attention in clinical practice. We aimed to construct an indicator of the functional fitness age(FFA) of women aged 50 and older by an equation using fitness outcomes and its correlation with chronological age(CA) and to analyze the external validity of our results by comparing our sample to others.Methods: Participants(n=459, age: 70.3 ± 7.9 years, mean ± SD) were evaluated using the Senior Fitness Test battery. We applied a multiple regression and a subsequent Holt's exponential smoothing to analyze the outcomes.Results: We obtained a statistically significant expression of F(6, 452) = 328.384; p < 0.0005 in which the coefficients of the equation explain81% of variability(R_(corrected)~2 = 0.813). The equation correlates fitness assessment in women aged 50 and over with regards to CA:FFA = 40.146 + 0.350 X CS(stand)-0.714 X AC(rep)-0.110 X ST(step)-0.177 X CSR(cm)-0.101 X BS(cm) + 8.835 X FUG(s) where CS means chair stand test, AC. means arm curl test, ST means 2-min step test, CSR means chair sit-and-reach test, BS means back scratch test, FUG means 8-foot up-and-go test. We compared this index with percentiles distribution from our sample and from other studies.Conclusion: We suggest the use of FFA as a valid indicator of fitness in adult and senior women as well as a useful motivational tool to undertake exercise programs. | Edgar Johani Latorre-Rojas Joan Antoni Prat-Subirana Xavier Peirau-Terés Sebastià Mas-Alòs José Vicente Beltrán-Garrido Antoni Planas-Anzano | 2019 | Journal of Sport and Health Science2019，8，3： | 2 |
