Journal of Geographical Sciences 2012年第4期22卷 669-680页

作者： AGUIRRE-SALADO Carlos Arturo TREVINO-GARZA eduardo Javier AGUIRRE-CALDERON Oscar Alberto JImENEZ-PiEREZ Javier GONZALEZ-TAGLE marco Aurelio VALDEZ-LAZALDE Jose Rene m IRANDA-ARAGON Liliana AGUIRRE-SALADO Alejandro lvan Autonomous University of Nuevo Leon Linares NL 67700 Mexico Autonomous University of San Luis Potosi SLP 78290 Mexico The College of Postgraduates Texcoco MEX 56230 Mexico

Spatially-explicit estimation of aboveground biomass （AGB） plays an important role to generate action policies focused in climate change mitigation, since carbon （C） retained in the biomass is vital for regulating Earth＇s temperature. This work estimates AGB using both chlorophyll （red, near infrared） and moisture （middle infrared） based normalized vegetation indices constructed with mCD43A4 mODerate-resolution Imaging Spectroradiometer （mODIS） and mOD44B vegetation continuous fields （VCF） data. The study area is located in San Luis Potosi, mexico, a region that comprises a part of the upper limit of the intertropical zone. AGB estimations were made using both individual tree data from the National Forest Inventory of mexico and allometric equations reported in scientific literature. Linear and nonlinear （expo- nential） models were fitted to find their predictive potential when using satellite spectral data as explanatory variables. Highly-significant correlations （p = 0.01 ） were found between all the explaining variables tested. NDVI62, linked to chlorophyll content and moisture stress, showed the highest correlation. The best model （nonlinear） showed an index of fit （Pseudo - r2） equal to 0.77 and a root mean square error equal to 26.00 mg/ha using NDVI62 and VCF as explanatory variables. Validation correlation coefficients were similar for both models： linear （r = 0.87＊＊） and nonlinear （r = 0.86＊＊）.

Existence of a Limit Cycle in an Intraguild Food Web model with Holling Type II and Logistic Growth for the Common Prey

引用

Applied mathematics 2017年第3期8卷 358-376页

作者： Francisco eduardo Castillo-Santos miguel Angel Dela Rosa Iván Loreto-Hernández División Académica de Ciencias Básicas CONACyT-UJAT Cunduacán México

In this paper, we prove the existence of a limit cycle for a given system of differential equations corresponding to an asymmetrical intraguild food web model with functional responses Holling type II for the middle and top predators and logistic grow for the (common) prey. The existence of such limit cycle is guaranteed, via the first Lyapunov coefficient and the Andronov-Hopf bifurcation theorem, under certain conditions for the parameters involved in the system.

Parathyroid Embryology,Anatomy,and Pathophysiology of Primary Hyperparathyroidism

International Journal of Otolaryngology and Head & Neck Surgery 2017年第4期6卷 39-58页

作者： Rodrigo Arrangoiz Fernando Cordera David Caba manuel munoz Juarez eduardo moreno Enrique Luque American British Cowdray medical Center México CityMexico

Unregulated overproduction of parathyroid hormone (PTH) from an abnormal parathyroid gland is the origin of primary hyperparathyroidism (PHPT). Patients who have an elevated serum calcium concentration have a problem in one or more of their parathyroid glands. To understand this disease state adequately and provide appropriate treatment, a thorough understanding of parathyroid embryology, anatomy, physiology, and pathophysiology is essential. In this manuscript, we review our current understanding of parathyroid gland embryology, anatomy, histology, physiology, and pathophysiology.

＜正＞ micro fluidic oscillators were obtained from wall attachment micro fluidic amplifiers using a feedback loop from the outputs to the control inputs. These devices can be used as actuators, as mixers, and also as flow meters, when the oscillation frequency is proportional to the volumetric flow in subsonic and moderately compressible conditions. The devices were then made in a SU-8 based epoxy photo resist using photolithography ultraviolet process. The article shows the results obtained in the experimental tests of the devices with gases （nitrogen, argon, and carbon dioxide）. The dimensions are of the order of 280 urn. The typical variation of the frequency with volumetric flow presents a range close to thousands of Hz. The oscillation frequencies were obtained using hot wire filaments （in this case with 12 urn of diameter）. The experimental results indicated which operation of the micro fluidic oscillator were direct function of the length of feedback loop and the velocity inside of the interaction region.

The Impact of 18F-DCFPyL PSmA PET-CT in the management of Prostate Cancer Biochemical Recurrence

引用

Open Journal of Urology 2021年第11期11卷 393-403页

作者： Raquel García Virginia morillo Pablo Sopena miguel R. Soler maría Rodríguez Ana Aliaga Laura moral Carlos m. martínez eduardo Ferrer Carlos Ferrer Radiation Oncology University Clinical Hospital Valencia Spain Radiation Oncology Provincial Hospital Consortium Castellón Spain Nuclear medicine Vithas Hospital October 9 Valencia Spain

Purpose: We evaluated the findings from 18F-DCFPyL PSmA PET-CTs performed on patients presenting biochemical recurrence (BCR) of prostate cancer (PCa) and assessed its impact on staging. methods and materials: This was a multicenter retrospective analysis of patients with PCa and BCR who underwent 18F-DCFPyL PSmA PET-CT in 2020. The patients were stratified into two groups: BCR after prostatectomy (PSA ≥ 0.2 ng/mL) or BCR after radiotherapy (PSA ≥ 2 ng/mL + nadir). We analyzed the lesions according to number and location. The Shapiro-Wilk test was used to estimate the distribution of the variables. We calculated representative statistics for the quantitative variables including the mean, standard deviation, median, and interquartile range. The association between qualitative variables was examined using Chi-squared tests. Results: 40 patients with BCR were analyzed;67.5% presented disease progression, predominantly distant recurrence (42.5%), which was found exclusively in bone;55% presented ≤5 lesions and of these, 68.2% only presented 1 lesion. There was a change in staging in 66.7% of the cases;17.7% received ablative treatment with stereotactic radiotherapy (SABR). Conclusions: 18F-DCFPyL PSmA PET-CT represents a new way to manage patients with BCR that, in this study, resulted in a change in staging in 66.7% of cases and early identification of oligometastatic progressions in the subgroup of patients with PSA mL.

The present study reports a physicochemical comparison of shade-grown and sun-grown coffee beans, under unripe, rip and roasted-ripe conditions, using electrical conductivity measurements, electron paramagnetic resonance (EPR), infrared spectroscopy (FTIR), and high performance liquid chromatography (HPLC). moreover, the assessed physicochemical parameters were compared with organoleptic evaluations based on the Coffee Quality Institute protocol. The values found for electrical conductivity, leached potassium, and stable free radicals were respectively 29%, 31%, and 350% higher for shade-grown coffee beans, whereas polyphenol oxidase enzymatic activity was 23% lower. By contrast, FTIR and HPLC measurements identified higher chlorogenic acid and lipid contents in sun-grown coffee beans. Importantly, the sensorial grade attributed to roasted-ripe grains was 12% higher for sun-grown coffee. Our findings suggest that shade-grown coffee beans have undergone microorganismal activity and undesired fermentation during cultivation, which resulted in lower coffee quality. A correlation between a set of selected physicochemical properties and organoleptic properties was robustly established and could be used in the development of future coffee bean quality control protocols.
