Ion deposition

description: The Wasatch Mountains are a unique place to study deposition of ions in snow because of proximity to Salt Lake City, UT, home to 1.1 million people, and Great Salt  Lake, the world' fourth largest closed-basin saline lake. Prior study at low elevations of the Wasatch Mountains and in Salt Lake City indicates very high deposition (>1 mmol L-1) of chloride nitrate, sulfate, sodium and calcium ions in snow and rime during winter temperature inversions. At peak snowpack, concentrations (?eq L-1) and ecosystem loading (meq m-2) of major ion species (Cl-, NO3-, SO42-, H+, NH4+, Na+, Mg2+, K+, and  Ca2+) were measured at five sites in 2008 and 16 sites in 2009 in the Wasatch Mountains. Concentrations and loading of these ion species in snow were up to an order of magnitude higher than previously observed and were likely derived from salts that precipitated from Great Salt Lake as its elevation decreased. Great Salt Lake has very high salinity dominated by concentrations of chloride, sulfate, sodium and magnesium. Moderately strong correlations existed between concentrations of these ions in snow and distance from Great Salt Lake, suggesting it as a major source of ion deposition in the Wasatch Mountains. Concentrations and ecosystem loading of nitrate in snow were lower than expected, but total winter inorganic nitrogen deposition (NO3- and NH4+) was similar to observations at Niwot Ridge in the Rocky Mountains of Colorado. In general, concentrations of ions in snow decreased with elevation while  ecosystem loading of ions increased with elevation due to greater snow accumulation.

description: Species of Erythroxylum genus are popularly used as anti-inflammatories and in the treatment of renal and respiratory disorders. Although it has been reported that species from the Erythroxylum genus induce cardiovascular effects, E. passerinum had not been studied specifically in this respect. However, previous phytochemical studies of E. passerinum demonstrated the presence of compounds which can have potential activity on the cardiovascular system. In this study, phytochemical screening of the ethanol extract of E. passerinum (EEEP) detected polyphenols, but not alkaloids. EEEP caused hypotension, bradycardia and vasorelaxation in rats. The vasorelaxation was attenuated by Nw-nitro-L-arginine methyl ester (L-NAME) or L-NAME + indomethacin (INDO), but not by INDO alone. Vasorelaxation was also significantly attenuated after endothelium removal or after incubation with high K+, 4-aminopyridine, glibenclamide or tetraethylammonium, but was not affected by pre-contraction with serotonin. Thus, EEEP induces hypotension and endothelium-dependent and independent vasorelaxation, which seems to involve the nitric oxide and K+-channels.

description: Abstract 

In countries of the South, hydatid cyst disease is an endemic parasitic condition that can sometimes lead to serious complications. Spontaneous rupture of the cyst through the abdominal wall is extremely rare, and very few cases have been reported in the medical literature. We report the case of a 47-year-old man with multiple, previously unrecognized hydatid cysts, one of which spontaneously fistulized to the abdominal wall, revealing the disease. The diagnosis was established based on clinical examination, radiographs, and serological tests. The patient underwent surgical treatment and received perioperative albendazole chemotherapy, with uncomplicated postoperative recovery.

description: This thesis is composed of three chapters. Chapter 1 introduces a statistical framework to study dynamic (S,s) economies. The proposed framework enables researchers to estimate unit level cumulated changes in frictionless variables based on a panel of variables for which changes are intermittent and lumpy. Formally, the estimates are grounded on an exact closed-form solution for the smoothing problem associated with a nonlinear and non-Gaussian state-space representation of an economy composed of microeconomic unit pursuing two-sided (S,s) policies subject to costless adjustment opportunities. This state-space representation is semi-structural and can accommodate some classic problems that have been analysed through the lens of (S,s) models such as pricing subject to menu costs, cash withdrawals and plant-level investment and hiring and firing decisions. The resulting unit level estimates can be used to construct estimates of frictionless aggregate variables and of the cross-sectional distribution of state gaps for any time period. Chapter 2 applies the theoretical results developed in chapter 1 to a large micro price dataset underlying the United Kingdom Consumer Price Index to produce a novel measure of in inflation which I label frictionless in ation. This measure is theoretically grounded on a random menu cost model and it should be interpreted as the in ation that would have been observed in a counterfactual world where menu costs of price adjustment did not exist. I use this measure to answer four questions. First, what is the importance of menu costs for the aggregate in inflation dynamics? Second, what is the importance of menu costs for the transmission of monetary policy shocks? Third, what is the relationship between frictionless in ation and the movements in the output gap? Fourth, can frictionless in inflation be used as a leading indicator for headline in inflation? Chapter 3 studies the estimation of impulse responses functions (IRFs) of different individuals to an aggregate shock. The commonplace approach to this 3 problem involves first grouping individuals according to some external classification or observable explanatory variables and subsequently estimating the associated group-specific IRFs. This chapter starts by showing that the IRF estimates based on this approach are subject a misclassification bias that arises whenever the grouping of individuals imposed by the researcher groups together individuals that do not react in the same way to aggregate shocks. Motivated by this results, this chapter introduces an alternative methodology to estimate disaggregated IRFs using the C-Lasso framework which asymptotically eliminates the misclassification bias without the need for the researcher to take a stance on individual group membership. The proposed estimator is used to revisit the dynamic responses of firm-level debt to an aggregate investment specific technology shock.

description: The aim of this study was to investigate the effect of emodin derived from Polygonum multiflorum on melanin production in B16F1 cells. In this study, emodin did not show antioxidant activity in DPPH radical and reducing power assays. However, it was found that emodin scavenged intracellular H2O2. Emodin increased not only tyrosinase activity but also melanin synthesis in vitro. Moreover, emodin enhanced melanin synthesis by increasing the expression level of tyrosinase (TYR), tyrosine related protein (TRP)-1, TRP-2, MITF and SIRT1 proteins in live cells treated with H2O2 compared with H2O2 treatment group in the analyses of western blot and immunofluorescence. Moreover, emodin suppressed ERK activation by SIRT1 and FOXO1. Thus, emodin promoted melanin synthesis by increasing the expression of TRP-1, TRP-2, tyrosinase through the activation of MITF transcription factor. These findings suggest that emodin could promote melanin production related to anti-hair graying.

Thesis and dissertation georeferencing project

description: The South Fork of the Ogden River area is in eastern Weber County , Utah approximately two miles east of the town of Huntsville and comprises a portion of the northcentral Wasatch Mountains.  The rocks exposed in the area range in age from Pre- cambrian to Quaternary. The Precambrian consists of quart- zite, quartzitic sandstone, arkosite, and phyllite (10,000-feet) ; the Cambrian rocks are meta-quartzite', limestone, dolomite and shale (3500 feet); the Ordovician is limestone5 dolomite and shale (600+feet); the Silurian rocks are largely arenaceous dolomite (243- feet); the Devonian is dolomite, arenaceous limestone and dolomite, sandstone, and shale (1144 feet); the Mississippian system is represented largely by limestone and sandstone (3300- feet); the Pennsylvanian is limestone and sandstone. The Eocene Knight (?) formation, which once covered the entire area, is a cobble and boulder conglomerate with sandstone lenses; Quaternary deposits consist of Lake Bonneville sediments and alluvium. The Upper Cambrian and base of the Ordovician are not exposed in the area. The Paleozoic strata were found to correlate with the formations of the Logan auadrangle. Detailed measured sections are included.   Except for minor disconformities, sedimentation was probably continuous from Precambrian to Pennsylvanian time. No evidence for an unconformity could be found at the base of the Cambrian. The area is located very near the southern  limit of Ordovician and Silurian deposition; neither system is represented in the Uinta Mountains to the south.  The most important structural feature of the area is a north-trending syncline. The trace of the Willard (?) thrust is believed to be exposed in the western part of the area near Ogden Valley.

description: This dissertation presents the derivation of an approximate method to determine the mean and the variance of electromagnetic fields in the body using the Finite-Difference Time-Domain (FDTD) method. Unlike Monte Carlo analysis, which requires repeated FDTD simulations, this method directly computes the variance of the fields at every point in space at every sample of time in the simulation. This Stochastic FDTD simulation (S-FDTD) has at its root a new wave called the Variance wave, which is computed in the time domain along with the mean properties of the model space in the FDTD simulation. The Variance wave depends on the electromagnetic fields, the reflections and transmission though the different dielectrics, and the variances of the electrical properties of the surrounding materials. Like the electromagnetic fields, the Variance wave begins at zero (there is no variance before the source is turned on) and is computed in the time domain until all fields reach steady state. This process is performed in a fraction of the time of a Monte Carlo simulation and yields the first two statistical parameters (mean and variance). The mean of the field is computed using the traditional FDTD equations. Variance is computed by approximating the correlation coefficients between the constituitive properties and the use of the S-FDTD equations.  The impetus for this work was the simulation time it takes to perform 3D Specific Absorption Rate (SAR) FDTD analysis of the human head model for cell phone power absorption in the human head due to the proximity of a cell phone being used. In many instances, Monte Carlo analysis is not performed due to the lengthy  simulation times required. With the development of S-FDTD, these statistical analyses could be performed providing valuable statistical information with this information being provided in a small fraction of the time it would take to perform a Monte Carlo analysis.

Blood pressure - Measurement

description: Mean arterial blood pressures were measured peripherally in the upper and lower positions of the right leg, right arm, and left arm by a neonate oscillometric blood pressure machine. They also were compared to the mean arterial pressures measured centrally by an umbilical artery catheter or radial arterial line. The study consisted of 10 infants (3 males, 7 females) 1,200 grams or less. Measurements were obtained in each infant for 3 consecutive days. The data collected were analyzed by computer statistical analysis. The analysis revealed that day and day by location were significant. However, the standard deviations were so great that further analysis was not continued. The physiological significance of these findings was discussed. In order to obtain a correct clinical evaluation, the importance of knowing these physiological variances of blood pressure in infants was stressed.

A novel role for the tumor suppressor adenomatous polyposis coli in controlling retinoic acid production in the vertebrate intestine and retina

description: The role of the adenomatous polyposis coli (APC) tumor suppressor in regulating intestinal homeostasis has previously been attributed solely to its ability to antagonize canonical WNT signaling via negative regulation of the transcriptional co-activator ?-catenin. Recent studies, however, have suggested the possibility of an additional role for APC in positively regulating retinoic acid production. This dissertation provides powerful genetic evidence that APC promotes epithelial differentiation in the vertebrate intestine and retina by controlling retinoic acid production via positive regulation of retinol dehydrogenases. We have identified two novel retinol dehydrogenases, zRDHA and zRDHB, which are expressed in the zebrafish intestine and, as determined by knockdown experiments, are required for establishment of intestinal cell number and subsequent intestinal differentiation. Similar defects were observed in the intestine of APC mutant zebrafish larvae. Importantly, the defects in APC mutants, and zRDHA and zRDHB morphant intestines were rescued by the addition of exogenous retinoic acid. In addition, APC mutants were rescued by injection of zRDHA thereby establishing a genetic relationship between these two genes. The data herein define hoxc8 as a downstream target of APC and retinoic acid whose overexpression is capable of rescuing intestinal defects in APC and zRDHB morphants. Furthermore, the data presented here firmly distinguish RDHs, rather than RALDHs, as the retinoid biosynthetic enzymes which APC regulates to control retinoic acid production. The findings in this dissertation additionally establish a novel role for APC in regulating RA production in the developing retina. Consistent with defects in the retina of FAP patients, APC mutant zebrafish display molecular and morphological abnormalities in retinal differentiation, particularly in the ventral photoreceptor layer and retinal pigmented epithelium (RPE). These defects were rescued by application of retinoic acid or injection of a unique, RPE-specific retinol dehydrogenase, zRDHH. Knockdown of zRDHH resulted in ventral retinal abnormalities similar to those present in APC mutants and these defects were also rescued by retinoic acid. The data presented in this dissertation illuminate a novel genetic pathway that includes APC regulation of retinol dehydrogenases as a mechanism for promoting epithelial differentiation in the vertebrate intestine and retina.

Interaction between the Escherichia coli heat shock proteins DnaK and GrpE
Creators: name: Maddock, Anna Louise
Publisher: name: University of Utah
Year: 2012
Subjects: subject: Genetics
subject: FOS: Biological sciences

description: The DnaK, DnaJ and GrpE Escherichia coli proteins have been shown to work together as a chaperone system which functions to help dissolve protein aggregates, such as heat inactivated RNA polymerase, and to aid in assembly and disassembly of protein structures, such as that found at the origin of lambda DNA replication. The DnaK protein is thought to be divided into two distinct domains, the amino-terminal ATPase domain, and the carboxyl-terminal substrate interaction domain. In the chaperone system, DnaK provides the major chaperoning activities, whereas DnaJ and GrpE act as DnaK's cohorts, helping DnaK to better interact with its substrates, and to be recycled. In order to better understand the interaction between the DnaK and GrpE proteins, single copy and multicopy mutations in dnaK that could function to allow E. coli growth in the absence of grpE were selected and characterized both genetically and biochemically. The single copy mutations, dnaK325 and dnaK332 are point mutations in the amino-terminal, ATPase domain of DnaK. The multicopy mutations result in truncations, from 94 to 248 amino acids from the carboxyl-terminal end of the DnaK protein. Genetic and biochemical characterization of these mutants indicate that the GrpE protein helps DnaK to interact with and to release its substrates through (a) maintaining a proper balance between the ATP- and ADP-bound forms of DnaK, and (b) influencing the conformation of DnaK. They further indicate that the carboxyl-terminus of the DnaK protein acts as a negative regulator of the amino-terminal ATPase activity, and that the amino-terminus must be involved in substrate interaction.

description: COVID 19; an infectious disease; firstly identified in December 2019 in Wuhan, China and has since spread globally, resulting in an ongoing pandemic. Searching for protease inhibitors is a challenging task in controlling COVID 19. Genus Ficus is known to be a rich source of phenolic compounds. Metabolic profiling of leaves methanolic extract of Ficus microcarpa (Moraceae) revealed nine compounds (1–9) mainly phenolics. Docking studies concerning these compounds against SARS-CoV-2 main protease showed that quercetin 3,7-O-α-L-dirhamnoside (1) and rutin (3) possessed significant binding stability at the N3 binding site in different activity degrees, which is comparable with COVID-19 main protease inhibitor, darunavir. Our study suggests that compounds quercetin 3,7-O-α-L-dirhamnoside and rutin might be potential candidates for the development of therapies against SARS-CoV-2.

Three essays in applied international macroeconomics: causes of growth and stagnation in the 19th Century United States

description: This dissertation is composed of three essays on U.S. macroeconomic development in the 19th century. Its focus is on the role of international trade and finance in governing the pace and nature of domestic growth. I argue the balance of payments and the institutions that govern its development played a larger role in U.S. economic growth than is normally recognized. The first essay of the dissertation lays the theoretical groundwork for the subsequent papers. Recent literature in the economics of growth has suggested that the main determinant of growth differences lies in institutions and the political process. Thus, "proximate" causes of growth are determined by more "fundamental" national characteristics like the structure of property rights. I argue instead that the developmental orientation of the state emerges as fundamental in U.S. history. Most importantly, the federal government's role in shaping and establishing financial markets and a common money of account allowed the U.S. to escape external constraints on growth related to the capital account. The second paper tests the hypothesis that U.S. growth was balance of payments constrained. This paper provides estimates of the long and short-run import demand function. Structural break tests suggest a shift in import demand after the Civil War. This implies that over time, maintaining balance on current account became less relevant as a potential constraint on growth. As a result, external events like terms of trade shocks and changes in British monetary policy seem to have less of an impact on growth in the latter part of the century. I explain this decline in the income elasticity of imports as the result of the active developmental state. The final paper of the dissertation examines the economic crisis between the years 1837 and the early 1840s. While traditional narrative regards the crisis as a purely monetary event, it can alternatively be seen as a balance of payments problem following a common pattern among small open economies. I outline a model of assymetric balance of payments adjustment, which suggests that the pace of industrialization in England determines export prices and debt sustainability in the U.S.

description: Esta investigación es de tipo investigación acción y tuvo como objetivo general evaluar la incidencia de la comprensión lectora en enunciados matemáticos para solucionar problemas que involucran sistemas de ecuaciones lineales de tipo 2 x 2 en los estudiantes de grado 9° del colegio Nuevo San Andrés de los Altos. El estudio es de enfoque cualitativo, para el cual se aplicaron tres fases de investigación: diagnóstico, intervención y cierre. El corpus poblacional fue de 29 estudiantes, se utilizó como técnica, la implementación de una secuencia didáctica y se hizo una triangulación de la información para la recolección de datos, los cuales facilitaron el análisis de los resultados. Así, se obtuvo como resultado principal que, la mayoría de los estudiantes mejoraron en sus niveles de comprensión literal, inferencial e intertextual y, por ende, en la comprensión de enunciados matemáticos. En el enfoque de solución de problemas mejoraron con respecto a: elaboración de un plan, ejecución del plan, y verificación del resultado. Lo anterior permitió concluir que los niveles de comprensión lectora están estrechamente ligados a la comprensión de enunciados matemáticos para resolver problemas que involucran sistemas de ecuaciones lineales 2 x 2.
description: This research is of the action research type and its general objective was to evaluate the incidence of reading comprehension in mathematical statements to solve problems that involve systems of linear equations of the 2 x 2 type in 9th grade students of the school "Nuevo San Andrés de los Altos". The study has a qualitative approach, for which three research phases were applied: diagnosis, intervention and closure. The population corpus was 29 students, the implementation of a didactic sequence was used as a technique, and a triangulation of information was made for data collection, which facilitated the analysis of the results. Thus, the main result was that most of the students improved in their levels of literal, inferential and intertextual comprehension and, therefore, in the comprehension of mathematical statements. In the problem solving approach they improved with respect to: elaboration of a plan, execution of the plan, and verification of the result. This allowed us to conclude that reading comprehension levels are closely linked to comprehension of mathematical statements to solve problems involving systems of 2 x 2 linear equations.

description: Numerous reports describe the antioxidant and antimicrobial activity of polyphenols-rich plant extracts. The aim of this study was to determine the total polyphenols content (TPC), and the in vitro (DPPH, FRAP and TEAC) antioxidant and antibacterial activity of leaves and wood of six native woody species (Aspidosperma quebracho-blanct, Sarcomphalus mistol, Geoffroea decorticans, Prosopis chilensis, Larrea divaricata and Larrea cuneifolia) from Catamarca. Also, the phenolic profile was determined in the species with higher activity. L. cuneifolia leaf extracts showed the highest antioxidant activity followed by L. divaricata and S. mistol, while S. mistol wood extracts showed the highest. Furthermore, Larrea species showed antibacterial activity against S. aureus and E. faecalis strains showing cidal effects mainly against S. aureus. Fifty-nine polyphenols were identified in leaves and wood of Larrea and S. mistol species, which are likely to be responsible for the different activities observed.
