The unfolded protein response (UPR) handles unfolded/misfolded proteins accumulated in the endoplasmic reticulum (ER). However, it is unclear how vertebrates correctly use the total of ten UPR transducers. We have found that ER stress occurs physiologically during early embryonic development in medaka fish and that the smooth alignment of notochord cells requires ATF6 as a UPR transducer, which induces ER chaperones for folding of type VIII (short-chain) collagen. After secretion of hedgehog for tissue patterning, notochord cells differentiate into sheath cells, which synthesize type II collagen. In this study, we show that this vacuolization step requires both ATF6 and BBF2H7 as UPR transducers and that BBF2H7 regulates a complete set of genes (Sec23/24/13/31, Tango1, Sedlin, and KLHL12) essential for the enlargement of COPII vesicles to accommodate long-chain collagen for export, leading to the formation of the perinotochordal basement membrane. Thus, the most appropriate UPR transducer is activated to cope with the differing physiological ER stresses of different content types depending on developmental stage. PMID:28500182

Puerto Rico was selected as one of the venues for the exhibit “From Earth to the Solar System” (FETTSS) during the month of October 2011. A set of outreach activities were organized to take place during the month of October aligned with the FETTSS themes. These activities included the following: 1) Main Exhibit, 2) Guided tours for school groups, 3) Planet Festival, 4) Film Festival and 5) Astronomy Conferences. We describe this experience and in particular the work with a group of undergraduate students from the University of Puerto Rico (UPR) that assisted in the outreach events. Among this group were three blind students. The FETTSS exhibit included a set of tactile and Braille images for the blind and visually impaired. A special exhibit was prepared with additional adapted materials for the visually impaired. This allowed blind visitors to participate and the general public to become more aware of the needs of this population.

Agricultural Abandonment, Suburban Growth, and Forest Expansion in Puerto Rico between 1991 and 2000

Full Text Available The response of local economies to the globalization process can have a large effect on population and land-use dynamics. In countries with a high population density and relatively high levels of education, the globalization process has resulted in a shift in the local economy from agriculture to manufacturing, technology, and service sectors. This shift in the economy has impacted land-use dynamics by decreasing agricultural lands, increasing urban growth, and in some cases, increasing forest cover. This process of economic and forest transition has been well documented in Puerto Rico for the period 1950 to 1990, but some authors predicted that poor planning and continued urban growth would eliminate the gains in forest cover. To investigate the impacts of recent economic changes, we evaluated demographic and land-use changes for 880 "barrios" (i.e., neighborhoods, the smallest administrative unit, in Puerto Rico using government census data from 1990 and 2000 and land-cover classifications from 1991 and 2000. During this period, the population increased by 284 127 people (8.2%. Most of the growth was in the suburban barrios, whereas urban barrios lost population. This shift was reflected by the construction of more than 100 000 housing units in suburban barrios. Although urban sprawl is perceived as the major land-cover change, urban cover only increased from 10% to 11% between 1990 and 2000, whereas the increase in forest cover was much greater (28% to 40%. Grasslands and shrublands were the major sources of new urban and forest areas in 2000. Although these results are encouraging in terms of increasing forest cover, most of the new development has been concentrated in the coastal plains, which are the location of most of the remaining agricultural areas, a few protected areas, and threatened ecosystems (e.g., mangroves.

Shade-grown coffee in Puerto Rico: Opportunities to preserve biodiversity while reinvigorating a struggling agricultural commodity

Shade-grown coffee contributes to biodiversity conservation and has many ecological benefits. We reviewed historical trends in coffee production and interviewed 100 coffee growers in 1999 to determine current management practices and attitudes toward the cultivation of sun and shade coffee in Puerto Rico. We discuss the outlook for the coffee industry in the 21st century and implications for biodiversity conservation, hoping lessons from Puerto Rico will apply to the international coffee industry. Throughout the 20th century, government intervention, including subsidies and technical assistance, supported coffee farming in Puerto Rico. In an effort to modernize coffee production and increase yields, the conversion from shade to sun coffee plantations was encouraged. Despite government support, the amount of land devoted to this once dominant agricultural commodity declined markedly between 1982 and 2007 (84%), due to labor shortages, low income, and catastrophic hurricanes. We found that a return to shaded plantations would be embraced by most farmers. Growers of shaded coffee were generally happier with their cultivation practices (89.3% satisfied) than growers of sun coffee (60.9% satisfied), valued biodiversity, and were willing to cultivate coffee under shade if given similar incentives to those received for farming sun coffee. The future of the coffee industry in Puerto Rico may depend on government programs that capitalize upon emerging markets for sustainably produced, shade-grown coffee. We conclude that where governments have close ties to the coffee industry, they should strive to wed economic development with the conservation of biodiversity and associated ecological services by providing support and incentives for the production of shade coffee. ?? 2011 Elsevier B.V.

Desalination Processes Evaluation at Common Platform: A Universal Performance Ratio (UPR) Method

KAUST Repository

Wakil Shahzad, Muhammad

2018-01-31

The inevitable escalation in economic development have serious implications on energy and environment nexus. The International Energy Outlook 2016 (IEO2016) predicted that the Non Organization for Economic Cooperation and Development (non-OECD) countries will lead with 71% rise in energy demand in contrast with only 18% in developed countries from 2012-2040. In Gulf Cooperation Council (GCC) countries, about 40% of primary energy is consumed for cogeneration based power and desalination plants. The cogeneration based plants are struggling with unfair primary fuel cost apportionment to electricity and desalination. Also, the desalination processes performance evaluated based on derived energy, providing misleading selection of processes. There is a need of (i) appropriate primary fuel cost appointment method for multi-purposed plants and (ii) desalination processes performance evaluation method based on primary energy. As a solution, we proposed exergetic analysis for primary fuel percentage apportionment to all components in the cycle according to the quality of working fluid utilized. The proposed method showed that the gas turbine was under charged by 40%, steam turbine was overcharged by 71% and desalination was overcharged by 350% by conventional energetic apportionment methods. We also proposed a new and most suitable desalination processes performance evaluation method based on primary energy, called universal performance ratio (UPR). Since UPR is based on primary energy, it can be used to evaluate any kind of desalination processes, thermally driven, pressure driven & humidification-dehumidification etc. on common platform. We showed that all desalination processes are operating only at 10-13% of thermodynamic limit (TL) of UPR. For future sustainability, desalination must achieve 25-30% of TL and it is only possible either by hybridization of different processes or by innovative membrane materials.

We examined whether the three unfolded protein response (UPR) signaling pathways, which are activated in response to endoplasmic reticulum (ER)-stress, are involved in progesterone production in the luteal cells of the corpus luteum (CL) during the mouse estrous cycle. The luteal phase of C57BL/6 female mice (8 weeks old) was divided into two stages: the functional stage (16, 24, and 48 h) and the regression stage (72 and 96 h). Western blotting and reverse transcription (RT)-PCR were performed to analyze UPR protein/gene expression levels in each stage. We investigated whether ER stress affects the progesterone production by using Tm (0.5 μg/g BW) or TUDCA (0.5 μg/g BW) through intra-peritoneal injection. Our results indicate that expressions of Grp78/Bip, p-eIF2α/ATF4, p50ATF6, and p-IRE1/sXBP1 induced by UPR activation were predominantly maintained in functional and early regression stages of the CL. Furthermore, the expression of p-JNK, CHOP, and cleaved caspase3 as ER-stress mediated apoptotic factors increased during the regression stage. Cleaved caspase3 levels increased in the late-regression stage after p-JNK and CHOP expression in the early-regression stage. Additionally, although progesterone secretion and levels of steroidogenic enzymes decreased following intra-peritoneal injection of Tunicamycin, an ER stress inducer, the expression of Grp78/Bip, p50ATF6, and CHOP dramatically increased. These results suggest that the UPR signaling pathways activated in response to ER stress may play important roles in the regulation of the CL function. Furthermore, our findings enhance the understanding of the basic mechanisms affecting the CL life span. Copyright © 2014 Elsevier Inc. All rights reserved.

The transition from adolescence to adulthood is associated with stressful adaptation experiences that may increase symptoms of depression. We explored the prevalence and sex differences of depressive symptoms and suicidal ideation in freshmen Latino college students in Puerto Rico, and identified stressful life events that could contribute to symptoms of depression. Two thousand one hundred sixty-three freshmen college students from the University of Puerto Rico (UPR) public education system were assessed for depression symptoms using the Beck Depression Inventory (BDI) and stressful life events using open questions. Nine percent of the sample reported depression symptoms at a moderate or severe level (BDI>20). Chi square analyses revealed a significantly higher prevalence for three of the stressful life events in females than males: relocation (10.2% females vs. 7.3% males; X(2) (1)=4.13, p=.042), break-up of a significant relationship (25.3% females vs. 17.8% males; X(2) (1)=13.76, pstressful life events are associated with an increased prevalence of depression symptoms. Early detection of depression and tailored prevention programs should be developed to improve both mental health and academic performance among the college population. Published by Elsevier B.V.

Full Text Available Carl Rogers has become a legendary personage in the mental health field. Rogers (1957 “has been cited in the literature over a thousandtimes, in professional writings originating in 36 countries” (Goldfried, 2007, p. 249. Clinicians in the behavioral health field (psychiatry, socialwork, counseling and psychology are exposed to his teachings about human behavior. Of all the ideas propagated by Rogers, the conceptof unconditional positive regard (UPR has been elevated to the level of a doctrine (Schmitt, 1980. What then is unconditional positive regard?How can clinicians be faithful to the demands of unconditional positive regard in the face of other competing realities such as threat of suicideor terrorism? This paper seeks to discuss the impossible nature of Rogers' UPR, highlighting its inherent linguistic contradiction. Sincepsychotherapy is culturally normative, the doctrine of unconditional positive regard negates this fundamental principle. In this article, the authortakes a critical look at the influence of American philosophy of education on Rogers – he was a product of his culture. Furthermore, this paperasserts that clinicians are guided by societal norms or “conditions” which regulate clinical practice, including unconditional positive regard(Gone, 2011.

An increasing number of studies have demonstrated that macroautophagy/autophagy plays an important role in the infectious processes of diverse pathogens. However, it remains unknown whether autophagy is induced in avian metapneumovirus (aMPV)-infected host cells, and, if so, how this occurs. Here, we report that aMPV subgroup C (aMPV/C) induces autophagy in cultured cells. We demonstrated this relationship by detecting classical autophagic features, including the formation of autophagsomes, the presence of GFP-LC3 puncta and the conversation of LC3-I into LC3-II. Also, we used pharmacological regulators and siRNAs targeting ATG7 or LC3 to examine the role of autophagy in aMPV/C replication. The results showed that autophagy is required for efficient replication of aMPV/C. Moreover, infection with aMPV/C promotes autophagosome maturation and induces a complete autophagic process. Finally, the ATF6 pathway, of which one component is the unfolded protein response (UPR), becomes activated in aMPV/C-infected cells. Knockdown of ATF6 inhibited aMPV/C-induced autophagy and viral replication. Collectively, these results not only show that autophagy promotes aMPV/C replication in the cultured cells, but also reveal that the molecular mechanisms underlying aMPV/C-induced autophagy depends on regulation of the ER stress-related UPR pathway.

Background and purpose: Tumour hypoxia contributes to failure of cancer treatment through its ability to protect against therapy and adversely influence tumour biology. In particular, several studies suggest that hypoxia promotes metastasis. Hypoxia-induced cellular changes are mediated by oxygen-sensitive signaling pathways that activate downstream transcription factors. We have investigated the induction and transcriptional regulation of a novel metastasis-associated gene, LAMP3 during hypoxia. Materials and methods: Microarray, quantitative PCR, Western blot analysis and immunohistochemistry were used to investigate hypoxic regulation of LAMP3. The mechanism for LAMP3 induction was investigated using transient RNAi and stable shRNA targeting components of the hypoxic response. Endoplasmic reticulum stress inducing agents, including proteasome inhibitors were assessed for their ability to regulate LAMP3. Results: LAMP3 is strongly induced by hypoxia at both the mRNA and protein levels in a large panel of human tumour cell lines. Induction of LAMP3 occurs as a consequence of the activation of the PERK/eIF2α/ATF4 arm of the unfolded protein response (UPR) and is independent of HIF-1α. LAMP3 is expressed heterogeneously within the microenvironment of tumours, overexpressed in breast cancer, and increases in tumours treated with avastin. Conclusions: These data identify LAMP3 as a novel hypoxia-inducible gene regulated by the UPR. LAMP3 is a new candidate biomarker of UPR activation by hypoxia in tumours and is a potential mediator of hypoxia-induced metastasis.

Transcriptional response of P. pastoris in fed-batch cultivations to Rhizopus oryzae lipase production reveals UPR induction

Full Text Available Abstract Background The analysis of transcriptional levels of the genes involved in protein synthesis and secretion is a key factor to understand the host organism's responses to recombinant protein production, as well as their interaction with the cultivation conditions. Novel techniques such as the sandwich hybridization allow monitoring quantitatively the dynamic changes of specific RNAs. In this study, the transcriptional levels of some genes related to the unfolded protein response (UPR and central metabolism of Pichia pastoris were analysed during batch and fed-batch cultivations using an X-33-derived strain expressing a Rhizopus oryzae lipase under control of the formaldehyde dehydrogenase promoter (FLD1, namely the alcohol oxidase gene AOX1, the formaldehyde dehydrogenase FLD1, the protein disulfide isomerase PDI, the KAR2 gene coding for the BiP chaperone, the 26S rRNA and the R. oryzae lipase gene ROL. Results The transcriptional levels of the selected set of genes were first analysed in P. pastoris cells growing in shake flask cultures containing different carbon and nitrogen sources combinations, glycerol + ammonium, methanol + methylamine and sorbitol + methylamine. The transcriptional levels of the AOX1 and FLD1 genes were coherent with the known regulatory mechanism of C1 substrates in P. pastoris, whereas ROL induction lead to the up-regulation of KAR2 and PDI transcriptional levels, thus suggesting that ROL overexpression triggers the UPR. This was further confirmed in fed-batch cultivations performed at different growth rates. Transcriptional levels of the analysed set of genes were generally higher at higher growth rates. Nevertheless, when ROL was overexpressed in a strain having the UPR constitutively activated, significantly lower relative induction levels of these marker genes were detected. Conclusion The bead-based sandwich hybridization assay has shown its potential as a reliable instrument for quantification of

2016-09-01

To evaluate the prevalence of diabetes mellitus in the surgical population of the University of Puerto Rico (UPR)-affiliated hospitals. We examined all the surgical cases that were entered into the Surgical Database from April 1, 2014 through September 30, 2014. This database collects patient and procedural information from different surgical services of various UPR-affiliated hospitals (the University District Hospital, the University Pediatric Hospital, the UPR Carolina Hospital, the Dr. Isaac Gonzalez Oncologic Hospital, the PR Cardiovascular Center [thoracic service], the Pavia Hospital [colorectal service], and the Auxilio Mutuo Hospital [colorectal and oncological services]). The prevalence of diabetes mellitus (types 1 and 2 combined) was estimated, and the nondiabetic and diabetic groups were compared. The difference between groups was evaluated using a Chi2 test, Student's t-test, or ANOVA, whichever was appropriate, with a p-value of less than 0.05 being considered significant. Information from 2,603 surgical patients was available. The mean age of the group was 49 (±23) years. The gender distribution indicated that 56% were women and 44% were men. Diabetes was present in 21% of the surgical population, increasing to 40% in patients aged 65 and over. The surgical procedures most frequently required by diabetic patients were in the categories of general surgery (36%), colorectal surgery (22%), vascular surgery (16%) and oncologic surgery (14%). Complications (5%, diabetic group vs. 2%, nondiabetic group; p diabetic group vs. 0.2%, nondiabetic group; p diabetic group than in the nondiabetic group. Our surgical population has a high prevalence of diabetes, and these diabetic patients showed higher complication and mortality rates from surgery than did the non-diabetic patients. Surgeons must consider the specific needs of these diabetic patients in order to provide optimal care.

Effects of UPR and ERAD pathway on the prolyl endopeptidase production in Pichia pastoris by controlling of nitrogen source.

Science.gov (United States)

Wang, Xiao-Dong; Jiang, Ting; Yu, Xiao-Wei; Xu, Yan

2017-07-01

Prolyl endopeptidase (PEP) is very useful in various industries, while the high cost of enzyme production remains a major obstacle for its industrial applications. Pichia pastoris has been used for the PEP production; however, the fermentation process has not be investigated and little is known about the impact of excessive PEP production on the host cell physiology. Here, we optimized the nitrogen source to improve the PEP expression level and further evaluated the cellular response including UPR and ERAD. During methanol induction phase the PEP activity (1583 U/L) was increased by 1.48-fold under the optimized nitrogen concentration of NH 4 + (300 mmol/L) and casamino acids [1.0% (w/v)] in a 3-L bioreactor. Evaluated by RT-PCR the UPR and ERAD pathways were confirmed to be activated. Furthermore, a strong decrease of ERAD-related gene transcription was observed with the addition of nitrogen source, which contributed to a higher PEP expression level.

Early dengue virus protein synthesis induces extensive rearrangement of the endoplasmic reticulum independent of the UPR and SREBP-2 pathway.

Directory of Open Access Journals (Sweden)

José Peña

Full Text Available The rearrangement of intracellular membranes has been long reported to be a common feature in diseased cells. In this study, we used dengue virus (DENV to study the role of the unfolded protein response (UPR and sterol-regulatory-element-binding-protein-2 (SREBP-2 pathway in the rearrangement and expansion of the endoplasmic reticulum (ER early after infection. Using laser scanning confocal and differential interference contrast microscopy, we demonstrate that rearrangement and expansion of the ER occurs early after DENV-2 infection. Through the use of mouse embryonic fibroblast cells deficient in XBP1 and ATF6, we show that ER rearrangement early after DENV infection is independent of the UPR. We then demonstrate that enlargement of the ER is independent of the SREBP-2 activation and upregulation of 3-hydroxy-3-methylglutaryl-Coenzyme-A reductase, the rate-limiting enzyme in the cholesterol biosynthesis pathway. We further show that this ER rearrangement is not inhibited by the treatment of DENV-infected cells with the cholesterol-inhibiting drug lovastatin. Using the transcription inhibitor actinomycin D and the translation elongation inhibitor cycloheximide, we show that de novo viral protein synthesis but not host transcription is necessary for expansion and rearrangement of the ER. Lastly, we demonstrate that viral infection induces the reabsorption of lipid droplets into the ER. Together, these results demonstrate that modulation of intracellular membrane architecture of the cell early after DENV-2 infection is driven by viral protein expression and does not require the induction of the UPR and SREBP-2 pathways. This work paves the way for further study of virally-induced membrane rearrangements and formation of cubic membranes.

XBP1-Independent UPR Pathways Suppress C/EBP-β Mediated Chondrocyte Differentiation in ER-Stress Related Skeletal Disease.

Full Text Available Schmid metaphyseal chondrodysplasia (MCDS involves dwarfism and growth plate cartilage hypertrophic zone expansion resulting from dominant mutations in the hypertrophic zone collagen, Col10a1. Mouse models phenocopying MCDS through the expression of an exogenous misfolding protein in the endoplasmic reticulum (ER in hypertrophic chondrocytes have demonstrated the central importance of ER stress in the pathology of MCDS. The resultant unfolded protein response (UPR in affected chondrocytes involved activation of canonical ER stress sensors, IRE1, ATF6, and PERK with the downstream effect of disrupted chondrocyte differentiation. Here, we investigated the role of the highly conserved IRE1/XBP1 pathway in the pathology of MCDS. Mice with a MCDS collagen X p.N617K knock-in mutation (ColXN617K were crossed with mice in which Xbp1 was inactivated specifically in cartilage (Xbp1CartΔEx2, generating the compound mutant, C/X. The severity of dwarfism and hypertrophic zone expansion in C/X did not differ significantly from ColXN617K, revealing surprising redundancy for the IRE1/XBP1 UPR pathway in the pathology of MCDS. Transcriptomic analyses of hypertrophic zone cartilage identified differentially expressed gene cohorts in MCDS that are pathologically relevant (XBP1-independent or pathologically redundant (XBP1-dependent. XBP1-independent gene expression changes included large-scale transcriptional attenuation of genes encoding secreted proteins and disrupted differentiation from proliferative to hypertrophic chondrocytes. Moreover, these changes were consistent with disruption of C/EBP-β, a master regulator of chondrocyte differentiation, by CHOP, a transcription factor downstream of PERK that inhibits C/EBP proteins, and down-regulation of C/EBP-β transcriptional co-factors, GADD45-β and RUNX2. Thus we propose that the pathology of MCDS is underpinned by XBP1 independent UPR-induced dysregulation of C/EBP-β-mediated chondrocyte differentiation

Sand and gravel resources of Puerto Rico

Science.gov (United States)

Rodriguez, Rafael W.

Many of Puerto Rico's beaches are eroding, and though rates of erosion vary, it is a major concern for the tourism and residential development industries. More than 85 percent of the population lives within 7 kilometers of the coast and they are heavily dependent on tourists that are attracted by the island's beaches and coral reefs. High-quality scientific data are needed to help formulate public policy regarding residential and commercial construction along the coast, beach replenishment, and future use of marine resources. Scientists have long recognized that the causes of coastal land loss are not limited to a relative rise in sea level, but can be manmade as well. For example, sediment supply to beaches especially along the north shore of Puerto Rico has been strongly affected by upstream river channeling, dam construction, various agricultural practices, paving and urbanization, as well as shallow-water oceanographic processes. The response to coastal erosion in Puerto Rico has been mostly crisis based leading to engineered solutions that have a negative effect on the coastal environment.

Primary factors affecting water quality and quantity in four watersheds in Eastern Puerto Rico

Science.gov (United States)

Murphy, Sheila F.; Stallard, Robert F.

2009-01-01

As part of the U.S. Geological Survey (USGS) Water, Energy, and Biogeochemical Budgets (WEBB) program, four small watersheds in eastern Puerto Rico were monitored to identify and evaluate the effects of geology, landcover, atmospheric deposition, and other factors on stream water quality and quantity. Two catchments are located on coarse-grained granitic plutonic rocks, which weather to quartz- and clay-rich, sandy soils, and two are located on fine-grained volcanic rocks and volcaniclastic sediments, which weather to quartz-poor, fine-grained soils. These differing soil materials result in different hydrologic regimes. Soils on the granitic rocks have greater permeability than those developed on the volcaniclastic rocks, allowing more water infiltration and potentially greater landslide erosion rates. For each bedrock type, one catchment was covered with mature rainforest, and the other catchment was affected by agricultural practices typical of eastern Puerto Rico. These practices led to the erosion of much of the original surface soil in the agricultural watersheds, which introduced large quantities of sediment to stream channels. The agricultural watersheds are undergoing natural reforestation, like much of Puerto Rico. Eastern Puerto Rico receives large atmospheric inputs of marine salts, pollutants from the Northern Hemisphere, and Saharan Desert dust. Marine salts contribute over 80 percent of the ionic charge in precipitation, with peak inputs in January. Intense storms, mostly hurricanes, are associated with exceptionally high chloride concentrations in stream waters. Temperate pollution contributes nitrate, ammonia, and sulfate, with maximum inputs during northern cold fronts in January, April, and May. Pollution inputs have increased through time. Desert dust peaks in June and July, during times of maximum dust transport from the Saharan Desert across the Atlantic Ocean.

La ciencia del tabaco en Puerto Rico, 1900-1940

Levy, Teresita

2015-06-01

Full Text Available Tobacco became an important export product in Puerto Rico after the American occupation of 1898, in large part, because of investments in the scientific study of tobacco: its efficient cultivation, its economic structure and its marketing. Scientific experimentation and the practical application of research findings in tobacco farms provided an arena for significant collaborative relationships between tobacco growers, scientists in Puerto Rico and the U.S., and the insular and federal governments. The involvement of Puerto Ricans in the science of tobacco, including their support of scientific inquiry, their continued demands for funding and beneficial agricultural legislation, and their adoption of modern agricultural technology, demonstrate that rather than being observers of rapid economic changes, they were activists, using the democratic guarantees available under the U.S. colonial structure to improve their economic situation.El tabaco se convirtió en un importante producto de exportación para Puerto Rico después de la ocupación norteamericana de 1898, debido a las inversiones en su estudio científico: el cultivo eficiente, la estructura económica y el mercadeo.

In many countries where the economy has shifted from mainly agricultural to industrial, abandoned agricultural lands are lost to urbanization. For more than 4 centuries the Puerto Rican economy depended almost entirely on agriculture, but sociopolitical changes early in the 20th century resulted in a shift to industry. This shift in the economy, and an increase in...

A committee has been established at the University of Puerto Rico to organize the local IYA2009 activities in the island and coordinate the international global activities. We are coordinating efforts with the members of the PR-NASA Space Grant Consortium, local government agencies, and non-profit organizations interested in education. We plan to have events throughout the island taking care to facilitate the participation of families and youth from economically disadvantaged communities. We wish that all the activities in 2009 emphasize the value of personal effort in reaching your goals, the importance of mathematics in modern life and the development of scientific awareness. Aligned with the IYA2009 major goals and considering the particular needs of our community, we have selected 8 core activities for Puerto Rico. This poster describes how we will celebrate. The inauguration event will be at the UPR with an invited guest speaker. During the year we will have a conference cycle throughout the island. A prototype insert is presented that will serve as model for a collectible Astronomy series to be published each month in the newspaper. We are planning to commemorate the 40th anniversary of the first human on the Moon with an astronaut as a special guest. An Astronomy fair centered on the exhibit "From Earth to the Universe” is being organized. During the year we will have a theatrical performance "La Vida en Marte y Otras Crueles Realidades” by Roberto Ramos-Perea and a musical performance of Gustav Holst's "The Planets” with the presentation of astronomical videos by Dr. Salgado from Adler Planetarium. Star parties will be held at different strategic locations. A group of volunteer undergraduate students ("Starry Messengers") will assist in these activities. The details of these events may be found at http://www.astronomypr.org .

UPR/Mayaguez High Energy Physics

Energy Technology Data Exchange (ETDEWEB)

Mendez, Hector [Univ. of Puerto Rico, Mayaguez (Puerto Rico)

2014-10-31

This year the University of Puerto Rico at Mayaguez (UPRM) High Energy Physics (HEP) group continued with the ongoing research program outlined in the grant proposal. The program is centered on the Compact Muon Solenoid (CMS) experiment at the proton-proton (pp) collisions at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. The main research focus is on data analysis and on the preparation for the High Luminosity (HL) LHC or experiment detector upgrade. The physics data analysis included Higgs Doublet Search and measurement of the (1) Λ⁰_b branching fraction, (2) B meson mass, and (3) hyperon θ^-_b lifetime. The detector upgrade included work on the preparations for the Forward Pixel (FPIX) detector Silicon Sensor Testing in a production run at Fermilab. In addition, the group has taken responsibilities on the Software Release through our former research associate Dr. Eric Brownson who acted until last December as a Level Two Offline Manager for the CMS Upgrade. In support of the CMS data analysis activities carried out locally, the UPRM group has built and maintains an excellent Tier3 analysis center in Mayaguez. This allowed us to analyze large data samples and to continue the development of algorithms for the upgrade tracking robustness we started several years ago, and we plan to resume in the near future. This project involves computer simulation of the radiation damage to be suffered at the higher luminosities of the upgraded LHC. This year we continued to serve as a source of outstanding students for the field of high energy physics. Three of our graduate students finished their MS work in May, 2014, Their theses research were on data analysis of heavy quark b-physics. All of them are currently enrolled at Ph.D. physics program across the nation. One of them (Hector Moreno) at New Mexico University (Hector Moreno), one at University of New Hampshire (Sandra Santiesteban) and one at University of

To determine the association between caffeinated-beverage consumption, self-perceived academic load, and self-perceived stress levels in first and second year students at UPR-MSC. A descriptive epidemiological study was performed using a self-administered anonymous questionnaire given to a representative stratified sample of 275 students. Questions included information regarding socio-demographic characteristics, academic load and stress indicators, and caffeinated-beverage consumption. Chi2 was used to assess the associations between these variables. Most participants were women (68%), aged 21-30 years (88%), with low annual household incomes (43%). Most perceived their academic loads as being heavy (68%), and most perceived their academic stress levels as being moderate (37%). Academic load was significantly correlated with stress level (pstress, and many (49%) reported that these beverages were useful for coping with stress. Energy drinks, in particular, were consumed more often by men compared to women (pstress or load. Consuming caffeinated beverages is a popular practice among participants in this sample, with soft drinks and coffee being the ones that are the most frequently consumed. No associations were found between the consumption of caffeinated beverages and academic stress or load.

Degraded and second growth tropical forests provide important ecosystem services, such as carbon sequestration and soil stabilization. Lidar data measure the three-dimensional structure of forest canopies and are commonly used to quantify aboveground biomass in temperate forest landscapes. However, the ability of lidar data to quantify second growth forest biomass in complex, tropical landscapes is less understood. Our goal was to evaluate the use of airborne lidar data to quantify aboveground biomass in a complex tropical landscape, the Caribbean island of Puerto Rico. Puerto Rico provides an ideal place for studying biomass accumulation because of the abundance of second growth forests in different stages of recovery, and the high ecological heterogeneity. Puerto Rico was almost entirely deforested for agriculture until the 1930s. Thereafter, agricultural abandonment resulted in a mosaic of second growth forests that have recovered naturally under different types of climate, land use, topography, and soil fertility. We integrated forest plot data from the US Forest Service, Forest Inventory and Analysis (FIA) Program with recent lidar data from NASA Goddard's Lidar, Hyperspectral, and Thermal (G-LiHT) airborne imager to quantify forest biomass across the island's landscape. The G-LiHT data consisted on targeted acquisitions over the FIA plots and other forested areas representing the environmental heterogeneity of the island. To fully assess the potential of the lidar data, we compared the ability of lidar-derived canopy metrics to quantify biomass alone, and in combination with intensity and topographic metrics. The results presented here are a key step for improving our understanding of the patterns and drivers of biomass accumulation in tropical forests.

Guzman-Rios, Senen; Garcia, Rene; Aviles, Ada

1987-01-01

INTRODUCTION Ground water is the principal source of drinking water for about 850,000 people in Puerto Rico (National Water Summary, 1985). Ground-water withdrawals for public supply, agricultural, and industrial water uses in Puerto Rico are about 250 million gallons per day (Mgal/d) (Torres-Sierra and Aviles, 1985). The development of the most accessible surface water supplies will result in an increasing demand for ground water. Recent investigations conducted by the U. S. Geological Survey, WRD (USGS) have shown the presence of toxic synthetic organic chemicals in ground water throughout Puerto Rico (Gomez-Gomez and Guzman-Rios, 1982). Volatile synthetic organic chemicals (VOC's) have been detected in water from public water supply wells in concentrations ranging from 1 to 500 micrograms per liter (Guzman-Rios and Quinones-Marquez, 1984 and Guzman-Rios and Quinones-Marquez, 1985). As result of these findings, pumpage was discontinued at 6 wells operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA), the Commonwealth of Puerto Rico agency responsible for public-water supply. Monitoring of 10 additional wells in the vicinity of those wells is being conducted by the USGS in cooperation with PRASA. In 1985, the USGS began a comprehensive islandwide study of VOC's in drinking water. The study was conducted in cooperation with the Puerto Rico Department of Health (PRDOH) and PRASA. Samples were collected from 243 public-water supply wells operated by PRASA (flgure 1). The authors wish to acknowledge the support, assistance and cooperation of the PRASA staff throughout Puerto Rico in the sample collection effort. The authors are especially grateful to Engineer Carlos Garcia-Troche from the PRASA main office in San Juan.

Spatial and seasonal patterns in fish assemblage in Corrego Rico, upper Parana River basin

Directory of Open Access Journals (Sweden)

Erico L. H Takahashi

Full Text Available The upper Paraná River basin drains areas of intensive industry and agriculture, suffering negative impacts. The Córrego Rico flows through sugar cane fields and receives urban wastewater. The aim of this work is to describe and to compare the fish assemblage structure in Córrego Rico. Six standardized bimonthly samples were collected between August 2008 and June 2009 in seven different stretches of Córrego Rico. Fishes were collected with an experimental seine and sieves, euthanized, fixed in formalin and preserved in ethanol for counting and identification. Data were recorded for water parameters, instream habitat and riparian features within each stretch. Non-metric multidimensional scaling, species richness and diversity analysis were performed to examine spatial and seasonal variation in assemblage structure. Fish assemblage structure was correlated with instream habitat and water parameters. The fish assemblage was divided in three groups: upper, middle and lower reaches. High values of richness and diversity were observed in the upper and lower stretches due to connectivity with a small lake and Mogi Guaçu River, respectively. Middle stretches showed low values of richness and diversity suggesting that a small dam in the middle stretch negatively impacts the fish assemblage. Seasonal differences in fish assemblage structure were observed only in the lower stretches.

There are limited studies in Puerto Rico that shows the water resources availability and variability with respect to changing climates and land use. The main goal of the HICE-PR (Human Impacts to Coastal Ecosystems in Puerto Rico (HICE-PR): the Río Loco Watershed (southwest coast PR) project which was funded by NASA is to evaluate the impacts of land use/land cover changes on the quality and extent of coastal and marine ecosystems (CMEs) in two priority watersheds in Puerto Rico (Manatí and Guánica).The main objective of this study is to set up a physically based spatially distributed hydrological model, Soil and Water Assessment Tool (SWAT) for the analysis of hydrological processes in the Rio Grande de Manati river basin. SWAT (soil and water assessment tool) is a spatially distributed watershed model developed to predict the impact of land management practices on water, sediment and agricultural chemical yields in large complex watersheds. For efficient use of distributed models for hydrological and scenario analysis, it is important that these models pass through a careful calibration and uncertainty analysis. The model was calibrated and validated using Sequential Uncertainty Fitting (SUFI-2) calibration and uncertainty analysis algorithms. The model evaluation statistics for streamflows prediction shows that there is a good agreement between the measured and simulated flows that was verified by coefficients of determination and Nash Sutcliffe efficiency greater than 0.5.

Cancer is a leading cause of morbidity and death in Puerto Rico. To set a baseline for identifying new trends and patterns of cancer incidence, Puerto Rico Central Cancer Registry staff and CDC analyzed data from Puerto Rico included in U.S. Cancer Statistics (USCS) for 2007-2011, the most recent data available. This is the first report of invasive cancer incidence rates for 2007-2011 among Puerto Rican residents by sex, age, cancer site, and municipality. Cancer incidence rates in Puerto Rico were compared with those in the U.S. population for 2011. A total of 68,312 invasive cancers were diagnosed and reported in Puerto Rico during 2007-2011. The average annual incidence rate was 330 cases per 100,000 persons. The cancer sites with the highest cancer incidence rates included prostate (152), female breast (84), and colon and rectum (43). Cancer incidence rates varied by municipality, particularly for prostate, lung and bronchus, and colon and rectum cancers. In 2011, cancer incidence rates in Puerto Rico were lower for all cancer sites and lung and bronchus, but higher for prostate and thyroid cancers, compared with rates within the U.S. Identifying these variations can aid evaluation of factors associated with high incidence, such as cancer screening practices, and development of targeted cancer prevention and control efforts. Public health professionals can monitor cancer incidence trends and use these findings to evaluate the impact of prevention efforts, such as legislation prohibiting tobacco use in the workplace and public places and the Puerto Rico Cessation Quitline in decreasing lung and other tobacco-related cancers.

Hydrologic conditions in the South Coast aquifer, Puerto Rico, 2010–15

Science.gov (United States)

Torres-Gonzalez, Sigfredo; Rodriguez, Jose M.

2016-01-15

In 1958, the U.S. Geological Survey began documenting hydrologic conditions, including groundwater levels, groundwater withdrawals for agricultural irrigation and public water supply, and water quality, in the South Coast aquifer, Puerto Rico. This information has improved the understanding of the water resources of the region. The hydrologic data indicate that (1) groundwater levels declined as much as 40 feet in the Salinas area and 11 feet in the Guayama area during 2012–14; (2) groundwater withdrawals for agricultural irrigation increased from 6.0 to 10.5 million gallons per day, or 75 percent, from 2010 to 2012; and (3) total groundwater withdrawals decreased from 29.3 to 23.8 million gallons per day from 2010 to 2014. The quantity and quality of water in the aquifer is primarily affected by variations in aquifer recharge as a result of changing rainfall or modes of irrigation; however, the spatial patterns and magnitude of water withdrawals for all uses have a secondary impact on the quantity and quality of water in the aquifer.

Analysis of 20th century rainfall and streamflow to characterize drought and water resources in Puerto Rico

Science.gov (United States)

Larsen, Matthew C.

2000-01-01

During the period from 1990 to 1997, annual rainfall accumulation averaged 87% of normal at the 12 stations with the longest period of record in Puerto Rico, a Caribbean island with a 1999 population of 3.8 million. Streamflow in rivers supplying the La Plata and Loíza reservoirs, the principal water supply of the San Juan metropolitan area, was at or below the 10th flow percentile for 27% to 50% of the time between December 1993 and May 1996. Diminished reservoir levels in 1994 and 1995 affected more than 1 million people in the San Juan metropolitan area. Water rationing was implemented during this period and significant agricultural losses, valued at $165 million, were recorded in 1994. The public endured a year of mandatory water rationing in which sections of the city had their water-distribution networks shut off for 24 to 36 hours on alternate days. During the winter and spring of 1997–1998, water was rationed to more than 200,000 people in northwestern Puerto Rico because water level in the Guajataca reservoir was well below normal for two years because of rainfall deficits. The drought period of 1993–1996 was comparable in magnitude to a drought in 1966–1968, but water rationing was more severe during the 1993–1996 period, indicating that water management issues such as demand, storage capacity, water production and losses, and per capita consumption are increasingly important as population and development in Puerto Rico expand.

In October, 1973, the Puerto Rico Water Resources Authority sought the initiation of studies aimed at determining background radiological characteristics of the northwestern quadrant of Puerto Rico using thermoluminescent dosemeters. Some of the studies were required for supporting data for the environmental report submitted as part of the licensing procedure in the establishment of thermonuclear electric power generation facilities in Barrio Islote, Arecibo, Puerto Rico. Previous studies of radiological characteristics of the area had been made using sodium iodide sensing equipment in an airplane flying at an altitude of 500 ft. The results are expressed in counts per second, and provide useful comparative levels for radioactivity measured with the thermoluminescent detectors. (U.S.)

Coastal ecosystems are an asset to many tropical island economies. In Puerto Rico, however, many invaluable coastal ecosystems are at risk due to multiple social and natural environmental stressors. To quantify the role of anthropogenic versus natural stressors, an integrated multidisciplinary approach was applied in two contrasting watersheds in Puerto Rico. The Rio Loco (RL) watershed in Southeastern Puerto Rico is hydrologically modified with interbasin water transfers, hydroelectric generation, and with water extraction for irrigation and water supply. Intensive agricultural production dominates both the lower and upper portions of the basin. In contrast, the Rio Grande de Manatí (RGM) shows a natural flow regime with minor flow regulation and limited agriculture. The Surface Water Assessment Tool (SWAT) was applied to each watershed to assess the effects of land use changes on water and sediment fluxes to coastal areas. From 1977 to 2016, forest areas increased in both watersheds due to the abandonment of farms in the mountains. However, in upper and lower RL, agricultural lands have remained active. Coffee plantations in the upper watershed contribute with high sediment loads, particularly in unpaved service roads. We hypothesize that water fluxes will be higher in the larger RGM than in RL. However, suspended sediment fluxes will be higher in the agriculturally active RL basin. A willingness-to-pay approach was applied to assess how residents from each watershed value water and coastal ecosystems revealing a general higher natural resources valuation in the RGM than in RL. Coastal ecosystems at each site revealed structural differences in benthic coral communities due to local currents influenced largely by coastal morphology. The optical properties of coastal waters are also being determined and linked to fluvial sediment fluxes. Stakeholder meetings are being held in each watershed to promote transfer of scientific insights into a sustainable coastal and

This project involved continued participation by the Physics Department at the Mayaguez Campus of the University of Puerto Rico (UPR) in high energy physics experiments carried out at Fermilab. The UPR is a member of the E831 collaboration which includes Fermilab and leading US, Italian, Brazilian and Korean universities. E831 is an upgrade to the E687 spectrometer with the goal of a tenfold increase in the statistics for the study of the photoproduction and decay of charmed particles. This spectrometer has been significantly upgraded to maintain and expand its capabilities even at considerably higher beam intensities. E687 completed its last data run in January 1992. Approximately 100,000 charm events were fully reconstructed from this data and results of the analysis have appeared in several publications. The UPR has been participating in E687 since 1985 when the experiment was in its early stages of construction. A grant from the DOE Division of High Energy Physics (starting in April 1994) and another from the DOE EPSCoR Program (starting in October 1994) allowed a considerable increase in the activities of the UPR group. Given the group's capable performance, the responsibilities assigned to it by the collaboration have increased to the point where they now include four major detectors in E831. All four detectors were ready on time for the start of the E831 run in July 1996. This is a remarkable performance if one considers that there is only one senior member in the group and that the students are all MS or undergraduate students. The group has also been active in the development of simulation, data acquisition and analysis software

The West Indian manatee (Trichechus manatus) populations in Florida (T. m. latirostris) and Puerto Rico (T. m. manatus) are considered distinct subspecies and are listed together as endangered under the United States Endangered Species Act. Sustained management and conservation efforts for the Florida subspecies have led to the suggested reclassification of the species to a threatened or delisted status. However, the two populations are geographically distant, morphologically distinct, and habitat degradation and boat strikes continue to threaten the Puerto Rico population. Here, 15 microsatellite markers and mitochondrial control region sequences were used to determine the relatedness of the two populations and investigate the genetic diversity and phylogeographic organization of the Puerto Rico population. Highly divergent allele frequencies were identified between Florida and Puerto Rico using microsatellite (F ST = 0.16; R ST = 0.12 (P ST = 0.66; Φ ST = 0.50 (P E = 0.45; NA = 3.9), were similar, but lower than those previously identified in Florida (HE = 0.48, NA = 4.8). Within Puerto Rico, the mitochondrial genetic diversity values (π = 0.001; h = 0.49) were slightly lower than those previously reported (π = 0.002; h = 0.54) and strong phylogeographic structure was identified (F ST global = 0.82; Φ ST global = 0.78 (P population size (N = 250), and distinct threats and habitat emphasize the need for separate protections in Puerto Rico. Conservation efforts including threat mitigation, migration corridors, and protection of subpopulations could lead to improved genetic variation in the endangered Puerto Rico manatee population.

La isla de Puerto Rico, localizada al noreste del Mar Caribe y sus islas principales, Vieques, Culebra e Isla de Mona, poseen humedales en abundancia . El clima subtropical, la lluvia abundante y las complejas formas topográficas y geológicas de estas islas dan origen a los humedales, que varían desde los raros e inusuales bosques cubiertos por nubes en las tierras altas, hasta los extensos manglares, yerbas marinas y arrecifes de coral a lo largo de las costas Norte y Sur. Sin embargo, los humedales en Puerto Rico han disminuido en los últimos siglos como resultado del aumento en el desarrollo agrícola, poblacional y turístico. Algunos tipos de humedales como los bosques de palo de pollo (Pterocarpus officinalis) se han reducido a sólo unos pocos remanentes (figura 1).Biológicamente hablando, los humedales de las islas están entre las áreas más productivas. Los humedales asociados con el bosque pluvial en las tierras altas del interior de Puerto Rico contienen varias plantas raras y especies de animales que no se encuentran en otras partes de la Isla. El agua de escorrentía proveniente de los humedales en las partes altas de la Isla proveen una fuente de agua que utilizan varias ciudades para abasto público. Los humedales costeros como los mangles, los colchones de yerbas marinas y los arrecifes de coral proveen áreas para la reproducción y crianza de varios peces, crustáceos y otras especies en la cadena alimenticia (López y otros, 1988). De esta manera, los humedales costeros contribuyen a la productividad biológica de las aguas llanas del mar alrededor de las islas . Los humedales también estabilizan las costas atrapando y reteniendo sedimentos no consolidados y amortiguan la acción de las olas y de las tormentas que tienen el potencial de causar daños en la zona.El valor de los humedales de Puerto Rico para la vida silvestre está muy bien documentado . Por ejemplo, las salinas de Cabo Rojo, en la costa suroeste, proveen áreas para el

UPR/Mayaguez High Energy Physics

International Nuclear Information System (INIS)

Lopez, Angel M.

2015-01-01

For the period of sixteen years covered by this report (June 1, 1997 - July 31, 2013) the High Energy Physics Group at the University of Puerto Rico's Mayaguez Campus (UPRM) carried out an extensive research program that included major experiments at Fermi National Accelerator Laboratory (Fermilab), the Cornell Electron-positron Collider and CERN. In particular, these were E831 (FOCUS) at Fermilab, CLEOc at Cornell and the Compact Muon Solenoid (CMS) at the Large Hadron Collider (LHC) at CERN. The group's history is one of successful execution and growth. Beginning with one faculty researcher in 1985, it eventually included four faculty researchers, one post-doctoral research associate, two undergraduates and as many as six graduate students at one time working on one of the experiments that discovered the Higgs boson. Some of this expansion was due to the group's leveraging of funds from the Department of Energy's core grant to attract funds from National Science Foundation programs not targeted to high energy physics. Besides the group's research productivity, its other major contribution was the training of a large number of MS students who later went on to successful technical careers in industry as well as academia including many who obtained PhD degrees at US universities. In an attempt to document this history, this final report gives a general description of the Group's work prior to June 1, 2010, the starting date for the last grant renewal period. Much more detail can, of course, be found in the annual reports submitted up to that date. The work during the last grant period is discussed in detail in a separate section. To summarize the group's scientific accomplishments, one can point to the results of the experiments. Both FOCUS and CLEOc were designed to carry out precise measurements of processes involving the heavy quarks, charm and bottom. Heavy quarks are particularly interesting because, due to their mass

2000-06-01

Full Text Available This study presents information on AIDS patients in Puerto Rico, including their general sociodemographic profile, some risk-related parameters, characteristics of vulnerable groups, and elements of the clinical spectrum of the disease. Data were analyzed from the Puerto Rico AIDS Surveillance Program and available studies about the HIV/AIDS epidemic in Puerto Rico. A total of 23 089 AIDS cases was reported to the Puerto Rico AIDS Surveillance Program from January 1981 through February 1999. The HIV/AIDS epidemic has affected mostly males and females between the ages of 30 and 49, though cases have also been reported for other age groups. The cumulative proportion of persons with AIDS who are women has increased tremendously, from 11.4% for the 1981-1986 period to 21.6% for the entire 1981-1999 period. In Puerto Rico the category of injecting drug users (IDUs accounts for the majority of the AIDS cases (52%, followed by heterosexual contact (22%, and men who have sex with men (17%. The three main diagnoses for AIDS on the island are wasting syndrome (30.7%; esophageal, bronchial, and lung candidiasis (29.4%; and Pneumocystis carinii pneumonia (26.8%. According to 1994 vital statistics for Puerto Rico, AIDS was the fourth-leading cause of death. The overall reported AIDS mortality rate was 42.0 per 100 000 persons, with the rate for males, 67.8, much higher than it was for females, 17.4. AIDS is the first cause of death among persons between 30 and 39 years old. Intense efforts are needed to better understand the epidemic in Puerto Rico and its biology, social and family impacts, and financial costs.Este estudio presenta información sobre los pacientes con sida en Puerto Rico, como su perfil sociodemográfico general, los factores de riesgo, las características de los grupos vulnerables y los elementos del espectro clínico de la enfermedad.

Medicamentos genéricos y de marca-Calidad e intercambiabilidad

Directory of Open Access Journals (Sweden)

Rua F.

2012-03-01

Full Text Available El interés por los medicamentos genéricos procede de la necesidad de los sistemas sanitarios de reducir la factura sanitaria sin merma de los objetivos de salud. Su expansión y uso requieren la aceptación de la población y de los profesionales. También requieren que se despejen algunas dudas sobre su verdadera equivalencia respecto a los medicamentos originales. Desde su introducción en el mercado farmacéutico existe el debate de si son correctamente investigados y de alta calidad. No son infrecuentes los conceptos equivocados entre los profesionales sobre los genéricos, en especial, el supuesto hecho de que pueden llegar a contener hasta un 20% menos de concentración en principio activo. Estas creencias erróneas sugieren una situación de desventaja en la eficacia y la tolerabilidad de los medicamentos genéricos comparados con sus equivalentes de marca, disminuyendo la credibilidad de los mismos. Así, en una encuesta realizada en 2008 los farmacéuticos opinaron que los genéricos y las marcas son diferentes en eficacia (26%, equivalencia (28% y, sobre todo, en la calidad del excipiente (46%, aumentando la percepción de que los genéricos son diferentes en función del laboratorio que los fabrica (52,8%. En este artículo, con el fin de ampliar los conocimientos sobre medicamentos genéricos, solucionar dudas y proporcionar información, objetiva, clara y rigurosa, se revisan los posibles prejuicios sobre genéricos y se exponen las evidencias que existen en torno a los mismos, como los requisitos de bioequivalencia de los productos genéricos, analizando si ésta corrobora adecuadamente la equivalencia terapéutica y de intercambio.

Leprosy in Puerto Rico: insight into the new millennia.

Science.gov (United States)

Valentín, Diana C; Candelario, Nicole; Carrasquillo, Osward Y; Figueroa, Luz; Sánchez, Jorge L

2017-04-01

Leprosy, or Hansen's disease, is a chronic infectious disease caused by the bacillus Mycobacterium leprae. In 2000, the World Health Organization (WHO) defined the elimination of the disease as a global prevalence of less than one case per 10,000 population. However, disease transmission is an ongoing worldwide public health concern, as evidenced by the more than 220,000 new cases diagnosed each year. This study is an update of the incidence and prevalence of leprosy in Puerto Rico for the period of 2000-2014. A retrospective analysis of data was obtained from the Tropical Disease Clinic (TDC) of the University of Puerto Rico School of Medicine. Sixty-three new cases of leprosy are detailed in this study. Disease incidence and prevalence were 1.65 and 5.26 per 100,000 inhabitants (of the island of Puerto Rico), respectively, and an average of 4.2 new cases per year. Most of the male patients in the study suffered from lepromatous leprosy (P = 0.026). In all, 47 (74.6%) patients had been born in Puerto Rico, and 29 (46%) had an affected family member or were in close contact with someone with leprosy. Compared to those of previous studies, these results demonstrate a decrease in both the incidence and prevalence of leprosy in Puerto Rico over the past 15 years. The relatively high prevalence of leprosy in Puerto Rico means that it remains endemic on the island. Concerted efforts must be undertaken to achieve the goal of the elimination of this old and stigmatized disease. © 2017 The International Society of Dermatology.

The purpose of this study was to determine the incidence of skin cancer in Puerto Rico in a selected year (2005) and to compare these findings with those previously reported for Puerto Rico in 1974 and 1981 and with other countries. The data was collected from the pathology reports corresponding to the period of January to December 2005 of 21 participating Pathology Laboratories throughout Puerto Rico. The rate and distribution of the main types of skin cancer was calculated based on sex, age, anatomic location and laterality. The incidence of skin cancer in Puerto Rico for 2005 was 6,568 cases, which represent a rate of 167.9 per 100,000 inhabitants. The most common type of skin cancer was basal-cell carcinoma. Skin cancer was more common in males except for melanoma, which was more common in females. The incidence increases with age on all types of skin cancer. The head and neck area was the most frequent location, except for melanoma in women, which was more common on the legs. The incidence rate was 41.5/100,000 in 1974, 52.5/100,000 in 1981 and 167.9/100,000 in 2005, a 305% increase. We found an increasing incidence of skin cancer in Puerto Rico when compared with previous reported data. This analysis provides a comprehensive evaluation of the epidemiology of skin cancer in Puerto Rico.

Recent Advances in Dengue: Relevance to Puerto Rico

Science.gov (United States)

Noyd, David H.; Sharp, Tyler M.

2015-01-01

Dengue represents an increasingly important public health challenge in Puerto Rico, with recent epidemics in 2007, 2010, and 2012–2013. Although recent advances in dengue vaccine development offer hope for primary prevention, the role of health professionals in the diagnosis and management of dengue patients is paramount. Case definitions for dengue, dengue with warning signs, and severe dengue provide a framework to guide clinical decision-making. Furthermore, the differentiation between dengue and other acute febrile illnesses, such as leptospirosis and chikungunya, is necessary for the appropriate diagnosis and management of cases. An understanding of dengue epidemiology and surveillance in Puerto Rico provides context for clinicians in epidemic and non-epidemic periods. This review aims to improve health professionals’ ability to diagnose dengue, and as highlight the relevance of recent advances in dengue prevention and management in Puerto Rico. PMID:26061055

Source, Use, and Disposition of Freshwater in Puerto Rico, 2005

Science.gov (United States)

Molina-Rivera, Wanda L.

2010-01-01

Water diverted from streams and pumped from wells constitutes the main sources of water for the 78 municipios of the Commonwealth of Puerto Rico. A better understanding is needed about water-use patterns, particularly about the amount of water used, where and how this water is used and disposed, and how human activities impact water resources. Irrigation practices, indoor and outdoor household uses, industrial uses, and commercial and mining withdrawals affect reservoirs, streams, and aquifers. Accurate and accessible water information for Puerto Rico is critical to ensure that water managers have the ability to protect and conserve this natural resource. The population of Puerto Rico increased 15 percent, from 3.4 million in 1985 to 3.9 million people 2005 and resulted in an increased demand for freshwater, mostly for the public-supply water use category. Almost 99 percent of the residents in Puerto Rico were served by public-supply water systems in 2005. One of the major challenges that water managers confront is the need to provide sufficient freshwater availability in the densely populated areas. Public-supply water is provided by the Puerto Rico Aqueducts and Sewers Authority (PRASA) and by non-PRASA systems. Non-PRASA systems refer to community-operated water systems (water systems that serve a rural or suburban housing area).

The Puerto Rico Healthcare Crisis.

Science.gov (United States)

Roman, Jesse

2015-12-01

The Commonwealth of Puerto Rico is an organized nonincorporated territory of the United States with a population of more than 3.5 million U.S. citizens. The island has been the focus of much recent attention due to the recent default on its debt (estimated at more than $70 billion), high poverty rates, and increasing unemployment. Less attention, however, has been given to the island's healthcare system, which many believe is on the verge of collapsing. Healthcare makes up 20% of the Puerto Rican economy, and this crisis affects reimbursement rates for physicians while promoting the disintegration of the island's healthcare infrastructure. A major contributor relates to a disparity in federal funding provided to support the island's healthcare system when compared with that provided to the states in the mainland and Hawaii. Puerto Rico receives less federal funding for healthcare than the other 50 states and the District of Columbia even though it pays its share of social security and Medicare taxes. To make matters worse, the U.S. Center for Medicaid and Medicare Services is planning soon to implement another 11% cut in Medical Advantage reimbursements. This disparity in support for healthcare is considered responsible for ∼$25 billion of Puerto Rico's total debt. The impact of these events on the health of Puerto Ricans in the island cannot be entirely predicted, but the loss of healthcare providers and diminished access to care are a certainty, and quality care will suffer, leading to serious implications for those with chronic medical disorders including respiratory disease.

Agricultural Incentives: Implications for Small-Scale and Subsistence Farming in the US Caribbean Islands

Science.gov (United States)

Alvarez-Berrios, N.; Parés-Ramos, I.; Gould, W. A.

2017-12-01

The effects of climate change threaten the world's most sensitive agroecosystems and our potential to reach agricultural productivity levels needed to feed a projected global population of 9.7 billion people by 2050. The US Caribbean agriculture is especially vulnerable to the effects of climate change, due to the region's frequent exposure to extreme weather events, its geographic and economic scale, shortage of labor force, and rapid urban expansion. Currently, agriculture contributes less than 1% of the island's GDP, and over 80% of the food consumed in the region is imported. Despite low production levels, there is widespread interest in reinvigorating the agricultural sector's contribution to the economy. Local and federal institutions play a major role strengthening the agricultural sector by providing access to incentives, loans, and education for best management practices. However, many of these efforts conform to agricultural systems of larger scale of production and temperate environments. In this study, we explore agricultural incentives programs and their implication for highly diverse, small-scale, and subsistence operations that characterize agricultural systems in Puerto Rico and the US Virgin Islands. We analyze records and maps from the USDA Farm Service Agency, to typify participating farms, and to track changes in land cover, farm size, crop diversity, practices, and production levels resulting from their enrollment in such programs. Preliminary results indicate that many incentives programs are not tailored to agricultural tropical systems and prescribe alternatives that exclude traditional farming methods employed in small-scale and subsistence farms (e.g. crop insurance that benefit monoculture over intercropped systems). Moreover, many of the incentives are contradictory in their recommendations (e.g., crop insurance benefit sun-grown coffee production, while best agricultural practices recommend agroforestry with shade-grown coffee

The migratory impact of minimum wage legislation: Puerto Rico, 1970-1987.

Science.gov (United States)

Santiago, C E

1993-01-01

"This study examines the impact of minimum wage setting on labor migration. A multiple time series framework is applied to monthly data for Puerto Rico from 1970-1987. The results show that net emigration from Puerto Rico to the United States fell in response to significant changes in the manner in which minimum wage policy was conducted, particularly after 1974. The extent of commuter type labor migration between Puerto Rico and the United States is influenced by minimum wage policy, with potentially important consequences for human capital investment and long-term standards of living." excerpt

[Legal secrecy: abortion in Puerto Rico from 1937 to 1970].

Science.gov (United States)

Marchand-Arias, R E

1998-03-01

The essay discusses abortion in Puerto Rico from 1937 to 1970, concentrating in its legal status as well as its social practice. The research documents the contradictions between the legality of the procedure and a social practice characterized by secrecy. The essay discusses the role of the Clergy Consultation Service on Abortion in promoting the legal practice of absortion in Puerto Rico. It also discusses the ambivalent role of medical doctors who, despite being legally authorized to perform abortions to protect the life and health of women, refused to perform the procedure arguing abortion was illegal. The essay concludes with a brief discussion on perceptions of illegality regarding abortion, emphasizing the contradictions between the practice of abortion and that of sterilization in Puerto Rico.

Caetano, Raul; Vaeth, Patrice A C; Canino, Glorisa

2018-04-01

Data on the prevalence and correlates of illegal drug use in Puerto Rico are now almost 20 years old. This study sought to estimate the 12-month prevalence of illegal and non-prescribed medical drug use in San Juan, Puerto Rico and identify sociodemographic correlates of use. Data are from a random household sample of 1510 individuals, 18-64 years of age in San Juan, Puerto Rico. The 12-month prevalence of any illegal or non-prescribed drug use was 16.5%. Prevalence among men (20.7%) was higher than among women (12.9%; chi 2  = 16.308; df = 1; p  .05) were negatively associated with drug use compared to annual income up to $10,000. As in many other places in the U.S., drug use in San Juan, Puerto Rico is high, affecting about 1 in 6 adults in the population. The highest prevalence is for marijuana use, which cannot be medically prescribed and of which recreational use is illegal on the island. Copyright © 2018 Elsevier B.V. All rights reserved.

Underuse of Radiation Therapy After Breast Conservation Surgery in Puerto Rico: A Puerto Rico Central Cancer Registry–Health Insurance Linkage Database Study

2017-05-01

Full Text Available Purpose: To identify rates of postoperative radiation therapy (RT after breast conservation surgery (BCS in women with stage I or II invasive breast cancer treated in Puerto Rico and to examine the sociodemographic and health services characteristics associated with variations in receipt of RT. Methods: The Puerto Rico Central Cancer Registry–Health Insurance Linkage Database was used to identify patients diagnosed with invasive breast cancer between 2008 and 2012 in Puerto Rico. Claims codes identified the type of surgery and the use of RT. Logistic regression models were used to examine the independent association between sociodemographic and clinical covariates. Results: Among women who received BCS as their primary definitive treatment, 64% received adjuvant RT. Significant predictors of RT after BCS included enrollment in Medicare (odds ratio [OR], 2.14; 95% CI, 1.46 to 3.13; P ≤ .01 and dual eligibility for Medicare and Medicaid (OR, 1.61; 95% CI, 1.14 to 2.27; P 2.0 cm and ≤ 5.0 cm (OR, 0.61; 95% CI, 0.40 to 0.93; P = .02 and those with tumor size > 5.0 cm (OR, 0.37; 95% CI, 0.15 to 0.92; P = .03 were found to be significantly less likely to receive RT. Conclusion: Underuse of RT after BCS was identified in Puerto Rico. Patients enrolled in Medicare and those who were dually eligible for Medicaid and Medicare were more likely to receive RT after BCS compared with patients with Medicaid alone. There were geographic variations in the receipt of RT on the island.

BIODYNAMIC AGRICULTURE - ECO-FRIENDLY AGRICULTURAL PRACTICE

Directory of Open Access Journals (Sweden)

Veselka Vlahova

2015-06-01

Full Text Available Biodynamic agriculture is undoubtedly the oldest organized agricultural movement in the world. It is considered as an organic agricultural farming approach and determined as the oldest organized alternative agricultural movement in the world. In 1924 Rudolf Steiner – an Austrian natural scientist and philosopher, carried out a series of eight lectures in Koberwitz, currently Kobierzyce- Poland, where he formulated his visions on changes in agriculture and revealed his spiritual and scientific concepts about the connection between nature and agriculture by determining the important role of agriculture for the future of humanity and thus he became known as “the father of anthroposophy”. The great ecological effect of the application of the biodynamic agriculture is expressed in soil preservation and preservation of the living organisms in the soil, as well as maintenance of the natural balance in the vegetable and animal kingdom.

Lessons Learned from the Puerto Rico Battery Energy Storage System

Energy Technology Data Exchange (ETDEWEB)

Boyes, John D.; De Anda, Mindi Farber; Torres, Wenceslao

1999-08-11

The Puerto Rico Electric Power Authority (PREPA) installed a battery energy storage system in 1994 at a substation near San Juan, Puerto Rico. It was patterned after two other large energy storage systems operated by electric utilities in California and Germany. The Puerto Rico facility is presently the largest operating battery storage system in the world and has successfully provided frequency control, voltage regulation, and spinning reseme to the Caribbean island. The system further proved its usefulness to the PREPA network in the fall of 1998 in the aftermath of Hurricane Georges. However, the facility has suffered accelerated cell failures in the past year and PREPA is committed to restoring the plant to full capacity. This represents the first repowering of a large utility battery facility. PREPA and its vendors and contractors learned many valuable lessons during all phases of project development and operation, which are summarized in this paper.

Hurricane Maria made landfall in Puerto Rico on September 20, 2017, causing major damage to infrastructure and severely limiting access to potable water, electric power, transportation, and communications. Public services that were affected included operations of the Puerto Rico Department of Health (PRDOH), which provides critical laboratory testing and surveillance for diseases and other health hazards. PRDOH requested assistance from CDC for the restoration of laboratory infrastructure, surveillance capacity, and diagnostic testing for selected priority diseases, including influenza, rabies, leptospirosis, salmonellosis, and tuberculosis. PRDOH, CDC, and the Association of Public Health Laboratories (APHL) collaborated to conduct rapid needs assessments and, with assistance from the CDC Foundation, implement a temporary transport system for shipping samples from Puerto Rico to the continental United States for surveillance and diagnostic and confirmatory testing. This report describes the initial laboratory emergency response and engagement efforts among federal, state, and nongovernmental partners to reestablish public health laboratory services severely affected by Hurricane Maria. The implementation of a sample transport system allowed Puerto Rico to reinitiate priority infectious disease surveillance and laboratory testing for patient and public health interventions, while awaiting the rebuilding and reinstatement of PRDOH laboratory services.

Full Text Available Intensive mining and processing of the polymetallic sulfide ore body of Cerro Rico de Potosí (Bolivia has occurred since 1545. To further investigate acid mine drainage (AMD discharges and their link to downstream contamination, data were gathered during two sampling events during the most extreme periods of the dry and wet seasons of one year. Concentrations of Ag, B, Ba, Mo, Sb, Se, Sn and V in AMD and receiving streams were greater than Bolivian discharge limits and receiving water body guidelines as well as international agricultural use standards. High concentrations of rare earth metals have been documented in this area. Results indicate that contamination from mining has a larger scope than previously thought and underscore the importance of remediation.

2001-01-01

In an attempt to develop novel markers for hypercholesterolemia, hepatic tissues and serum prepared from hypeicholesterolemic rat (i e RICO) were analyzed by two-dimensional electrophoresis (2DE) and matrix-assisted laser desorption ionization mass spectrometry (MALDI-ToF). Results were compared to those of paired inbreed rat (WKY). Comparative analysis of the respective spot patterns in 2DE revealed that the numbers of differential expression proteins were identified in serum and liver tissues of RICO. Some of the representative proteins annotated in 2DE were apolipoprotein family and numerous lipid metabolism related proteins. Especially, we found that protein disulfide isomerase subunits (ER-60) in 2DE have differential post-translational modification pattern by MALDI-ToF analysis. Our results suggest that the proteomic analysis of these proteins might be a novel approach to identify the molecular events in detail during lipid disorder such atherosclerosis

Women's employment and changing gender relations in Puerto Rico.

Science.gov (United States)

Warren, Alice Colón

2010-01-01

This article discusses Helen Safa's analyses of the impact of development strategies and social policies on gender relations and women headed families in the Caribbean and Puerto Rico. The discussion focuses on findings of a research project regarding patterns of women's employment, autonomy, marital relations, family headship and poverty in Puerto Rico in the decade beginning in the year 2000, using excerpts from interviews conducted with women workers displaced from a clothing and a tuna factory between 2001 and 2002 (Colón et al. 2008), as well as data from the Public Use Sample (PUMS) of the U.S. Census Puerto Rico Community Survey 2005-2007. It is argued that women's employment has resulted in advances in women's autonomy, gender equity, and renegotiations of the provider role, but, intensified by men's unstable earnings, it has also led to the increase of female family headship even among married women. Women's education and employment have been an important means of reducing family poverty both among dual earner families and female heads. Yet, the continuing joblessness in the Island places even higher educated sectors on the verge of economic precariousness.

Bibliometric assessment of cancer research in Puerto Rico, 1903-2005 Evaluación bibliométrica de la investigación sobre cáncer en Puerto Rico, 1903-2005

Directory of Open Access Journals (Sweden)

Ana P. Ortiz

2009-04-01

Full Text Available OBJECTIVE:The analysis of scientific production in Puerto Rico is largely unexplored. The main aim of this study is to present the characteristics and trends of cancer publications in Puerto Rico's biomedical journals and their relationship with the island's cancer mortality. METHODS:A PubMed and a hard-copy search were performed to retrieve cancer-related articles published in the Puerto Rico Health Sciences Journal and the Boletín de la Asociación Médica de Puerto Rico from 1903 to 2005. Bibliometric indicators studied included the number of authors and references by article, first author's institutional affiliation and country, document type, and language. The study type and tumor classification were also recorded. Cancer proportional mortality (M% in Puerto Rico and the proportion of cancer-related articles (P% published were also evaluated. The annual percent change (APC was estimated to assess trends. RESULTS:A total of 369 articles were retrieved. The institutions with the majority of publications were universities (39.6%, English was the predominant publication language (72.1%, and the principal document type was original papers (69.6%. Epidemiologic studies were the dominant study type (62.1%, and the most studied cancers were digestive (15.4% and gynecologic (9.6%. Although the P% has increased since 1913 (APC = 1.2%, the M% increased at a faster pace (APC = 2.7%. CONCLUSIONS: Although a growth in the number of cancer publications is observed in these journals, it does not parallel the increase in proportional mortality. A better understanding of the cancer publications in Puerto Rico is essential to establish priorities, define future areas of research, and develop cancer control strategies.OBJETIVO: El análisis de la producción científica de Puerto Rico está aún en gran parte pendiente. El objetivo principal de este estudio es presentar las características y las tendencias de las publicaciones sobre cáncer en las revistas

Molasses crisis in the Puerto Rico rum industry

Energy Technology Data Exchange (ETDEWEB)

Samuels, G

1980-01-01

In 1978 the Puerto Rico rum industry provided 85% of the US rum market, returning to the PR treasury $200 million in Federal excise taxes. The diminishing P.R. sugar industry is not able to supply sufficient blackstrap molasses (BSM) to the expanding P.R. rum industry, and at present imports from foreign suppliers amount to 88% of its needs. These imports place the rum industry in jeopardy, as these suppliers can boycott Puerto Rico to protect their own rum production, or they can insist by treaty that all rums claiming geographic origin (i.e., Puerto Rico rum) must be distilled from molasses produced in that country. Possible solutions to improve domestic molasses production are presented to eliminate these threats. The use of high-test molasses (HTM) would answer the present and future needs of the rum industry if produced by the energy cane (or biomass) concept. This is a management concept stressing total growth potential rather than sugar. It would permit doubling cane production per acre and produce sufficient HTM on 70,000 acres for the projected rum industry requirements. Considerations of HTM production show that problems exist with the marketing price rather than in the field or factory. The economics of HTM pricing will have to be worked out by the interested parties: the rum industry, the sugar industry, and the government.

Full Text Available Identifying factors that influence the attitudes of agricultural experts regarding precision agriculture plays an important role in developing, promoting and establishing precision agriculture. The aim of this study was to identify factors affecting the attitudes of agricultural experts regarding the implementation of precision agriculture. A descriptive research design was employed as the research method. A research-made questionnaire was used to examine the agricultural experts’ attitude toward precision agriculture. Internal consistency was demonstrated with a coefficient alpha of 0.87, and the content and face validity of the instrument was confirmed by a panel of experts. The results show that technical, economic and accessibility factors accounted for 55% of the changes in attitudes towards precision agriculture. The findings revealed that there were no significant differences between participants in terms of gender, field of study, extension education, age, experience, organizational position and attitudes, while education levels had a significant effect on the respondent’s attitudes.

Effect of land cover, stream discharge, and precipitation on water quality in Puerto Rico

Hall, J. S.; Uriarte, M.

2017-12-01

In 2015, Puerto Rico experienced one of the worst droughts in its history, causing widespread water rationing and sparking concerns for future resources. The drought represents precipitation extremes that provide valuable insight into the effects of land cover (LC), on modulating discharge and water quality indices at varying spatial scales. We used data collected from 38 water quality and 55 precipitation monitoring stations in Puerto Rico from 2005 to 2016, paired with a 2010 land cover map to (1) determine whether temporal variability in discharge, precipitation, or antecedent precipitation was a better predictor of water quality, (2) find the spatial scale where LC has the greatest impact on water quality, and (3) quantify impacts of LC on water quality indices, including dissolved oxygen (mg/L), total nitrogen (mg/L), phosphorous (mg/L), turbidity (NTRU), fecal coliforms (colony units/100mL) and instantaneous discharge (ft3/s). The resulting linear mixed effects models account for between 36-68% of the variance in water quality. Preliminary results indicate that phosphorous and nitrogen were best predicted from instantaneous stream discharge, the log of discharge was the better predictor for turbidity and fecal coliforms, and summed 2 and 14-day antecedent precipitation indices were better predictors for dissolved oxygen and discharge, respectively. Increased urban and pasture area reliably decreased water quality in relation to forest cover, while agriculture and wetlands had little or mixed effects. Turbidity and nitrogen responded to a watershed level LC, while phosphorous, fecal coliforms, and discharge responded to LC in 60 m riparian buffers at the watershed scale. Our results indicate that LC modulates changing precipitation regimes and the ensuing impacts on water quality at a range of spatial scales.

Highlights: → Unsaturated polyester resin (UPR) was synthesized from recycled PET. → Effect of surface treatment on EFB/UPR was studied. → Treatment on EFB improved the mechanical and thermal properties. → Treatment on EFB also improved fiber-matrix interaction. -- Abstract: Unsaturated polyester resin (UPR) was synthesized from recycled polyethylene terephthalate (PET) which acted as a matrix for the preparation of UPR/empty fruit bunch fibers (EFB) composite. Chemical recycling on fine pieces of PET bottles were conducted through glycolysis process using ethylene glycol. The unsaturated polyester resin (UPR) was then prepared by reacting the glycolysed product with maleic anhydride. FTIR analysis of glycolyzed product and prepared UPR showed that cross-links between unsaturated polyester chain and styrene monomer occurred at the unsaturated sites which resulted in the forming of cross-linking network. The preparation of UPR/EFB composite was carried out by adding EFB into prepared UPR matrix. The effects of surface treatment on EFB with sodium hydroxide solution (NaOH), silane coupling agent and maleic anhydride (MA) were then studied. The experimental results showed that treated EFB have higher values of tensile and impact strength compared with untreated EFB. The best results were obtained for silane treatment followed by MA and NaOH treatments where the tensile strength was increased by about 21%, 18% and 13% respectively. SEM micrographs of the tensile fracture surfaces of UPR/EFB composite also proved that treatment on EFB has increased the interfacial adhesion between the fiber and UPR matrix compared to the untreated UPR/EFB composite.

This paper describes SalHUD, a prototype web-based application for visualizing health data from Puerto Rico. Our initial focus was to provide interactive maps displaying years of potential life lost (YPLL). The public-use mortality file for year 2008 was downloaded from the Puerto Rico Institute of Statistics website. Data was processed with R, Python and EpiInfo to calculate years of potential life lost for the leading causes of death on each of the 78 municipalities in the island. Death records were classified according to ICD-10 codes. YPLL for each municipality was integrated into AtlasPR, a D3 Javascript map library. Additional Javascript, HTML and CSS programing was required to display maps as a web-based interface. YPLL for all municipalities are displayed on a map of Puerto Rico for each of the ten leading causes of death and for all causes combined, so users may dynamically explore the impact of premature mortality. This work is the first step in providing the general public in Puerto Rico with user-friendly, interactive, visual access to public health data that is usually published in numerical, text-based media.

Tourism and climate conditions in San Juan, Puerto Rico, 2000-2010

2014-06-01

Full Text Available The general behavior of the tourism sector in Puerto Rico, with its marked seasonality, hints at a close relationship between tourism activities and climate conditions. Even if weather condition is only one of many variables considered by travelling tourists, climate conditions weigh heavily in the majority of the decisions. The effect of climate variability on the environment could be manifested in warmer temperature, heat waves, and changes in the frequency of extreme weather events, such as severe storms and hurricanes, floods, and sea level rise. These conditions affect different sectors of society, among them public health and the economy. Therefore, our research has two main objectives: to establish a tourism climate index (TCI for Puerto Rico and to analyze if occupancy rates in hotels correspond to local weather conditions. Even though there are many other variables that could have positive or negative effects on tourism activities, results showed a significant association between occupancy rate in Puerto Rico and climate indexes. According to both TCI and the mean historical climate for tourism indexes, the most favorable months for tourism in Puerto Rico were February and March (winter, whereas the worst season was the end of August and the beginning of September (summer-fall. Although winter represents dry conditions and lower temperatures in San Juan, it also represents the highest occupancy rate during the years examined. In summer and fall, data showed high occupancy rates, yet climate conditions were not suitable; these months also correspond to the hurricane season. During this season, high relative occupancy rates responded to internal and local tourism patterns. It can therefore be assumed that until the climate-tourism relationship is well characterized, there is little hope of fully understanding the potential economic effects, detrimental or beneficial, of global climate change, not only on tourism in Puerto Rico, but on

The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on agriculture describes how climate change will affect primary agriculture production in Canada with particular focus on potential adaptation options, and vulnerability of agriculture at the farm level. Agriculture is a vital part of the Canadian economy, although only 7 per cent of Canada's land mass is used for agricultural purposes due to the limitations of climate and soils. Most parts of Canada are expected to experience warmer conditions, longer frost-free seasons and increased evapotranspiration. The impacts of these changes on agriculture will vary depending on precipitation changes, soil conditions, and land use. Northern regions may benefit from longer farming seasons, but poor soil conditions will limit the northward expansion of agricultural crops. Some of the negative impacts associated with climate change on agriculture include increased droughts, changes in pest and pathogen outbreaks, and moisture stress. In general, it is expected that the positive and negative impacts of climate change would offset each other. 74 refs., 2 tabs., 1 fig

Green Agriculture - features and agricultural policy measures for the transition to a sustainable agriculture

Cornelia Nistor

2015-12-01

Full Text Available Agriculture is one of the most important economic activities in each country or area, as it is in close correlation with all other the other economic activities, in a whole which must be structured so as to achieve a more efficient planning and organization of the territory. The practice of a traditional agriculture, based on industrialization, affects the natural environment through emissions of pollutants, waste and deforestation which together affects biodiversity. Green Agriculture suppose to empower managers to widespread the use of fertilizers, to improve the crop rotation, to realize a more efficient water consumption, to improve the storage methods and the supply chain of products. Agricultural policies are closely interrelated with environmental policies as agricultural activities have a considerable influence on the environment. The efficiency of agricultural policies is reflected in monetary transfers between agriculture and other economic sectors, in the costs due to the reallocation of the resources between different agricultural and non-agricultural activities and in the realized gains. Currently there is a constant concern of the governments for the transition to a green agriculture, and most countries recognize the importance of achieving sustainable economic development.

Unfolded protein response in filamentous fungi-implications in biotechnology.

Science.gov (United States)

Heimel, Kai

2015-01-01

The unfolded protein response (UPR) represents a mechanism to preserve endoplasmic reticulum (ER) homeostasis that is conserved in eukaryotes. ER stress caused by the accumulation of potentially toxic un- or misfolded proteins in the ER triggers UPR activation and the induction of genes important for protein folding in the ER, ER expansion, and transport from and to the ER. Along with this adaptation, the overall capacity for protein secretion is markedly increased by the UPR. In filamentous fungi, various approaches to employ the UPR for improved production of homologous and heterologous proteins have been investigated. As the effects on protein production were strongly dependent on the expressed protein, generally applicable strategies have to be developed. A combination of transcriptomic approaches monitoring secretion stress and basic research on the UPR mechanism provided novel and important insight into the complex regulatory cross-connections between UPR signalling, cellular physiology, and developmental processes. It will be discussed how this increasing knowledge on the UPR might stimulate the development of novel strategies for using the UPR as a tool in biotechnology.

Post-1898 Imaginative Geographies: Puerto Rico Migration in 1950s Film

Directory of Open Access Journals (Sweden)

Cynthia Tolentino

2011-12-01

Full Text Available This essay studies cultural representations of Puerto Rico’s economic boom and 1952 shift in legal status to the Commonwealth of Puerto Rico. It suggests that apprehending these events requires the reframing of Puerto Rican migration as global phenomena. Drawing on the historical and cultural scholarship on Puerto Rican migration, Operation Bootstrap, and US empire, Tolentino analyzes the famous musical film West Side Story (1961, but also the Hollywood film Sabrina (1954 and Island productions El Otro Camino (The Other Road, 1955 and Maruja (1958. In contrast to prevailing views, she interprets these films as narratives about migration and modernization that engage the discourse of sentimental modernization, the figure of the jíbaro, and the idea of small town Puerto Rico. In so doing, they reveal the global vision at the center of the Operation Bootstrap development plan and Commonwealth formation. The concluding section suggests how the films take up issues in Puerto Rico’s historiography. Rather than merely illuminating a forgotten historical period of 1950s Puerto Rico, the 1950s films negotiate Puerto Rico’s geographical, political, and cultural locations by rethinking institutionalized meanings of 1898 in discourses of Puerto Rico historiography and US empire. Proposing new ways of interpreting the introduction of the Commonwealth in 1952 makes possible the revision of dominant conceptions of 1898 rooted in nation, government, and constitutional law.

The IYA2009 inauguration in Puerto Rico was in January 2009. The local organizing committee includes members from the NASA Puerto Rico Space Grant Consortium, the Arecibo Observatory, the two astronomical societies of the island, private and public universities, local government agencies, and non-profit organizations interested in science education. The events are throughout the island, taking care to facilitate the participation of families and youth from disadvantaged communities. All the activities emphasize the value of personal effort to achieve your goals, the importance of mathematics in modern life and the development of scientific awareness. Aligned with the IYA2009 major goals and considering the particular needs of our community, we have selected eight core activities for Puerto Rico. Three of them have been completed (Inauguration, Theatrical performance of "La Vida en Marte y otras Crueles Realidades", 40th Anniversary of the first human on the Moon), three of them are underway (star parties, conference series, "From Earth to the Universe" (FETTU) exhibition) and the other two are under plan for the fall of 2009. A group of volunteer students ("Starry Messengers") are assisting in the activities. We present a project plan for the rest of 2009.

The most pressing problem in the effective management of the West Indian manatee (Trichechus manatus) in Puerto Rico is mortality due to human activities. We assessed 90 cases of manatee strandings in Puerto Rico based on historical data and a coordinated carcass salvage effort from 1990 through 1995. We determined patterns of mortality, including type of event, condition of carcasses, spatial and temporal distribution, gender, size/age class, and the cause of death. The spatial distribution of stranding events was not uniform, with the north, northeast, and south coasts having the highest numbers. Six clusters representing the highest incidence included the areas of Fajardo and Ceiba, Bahia de Jobos, Toa Baja, Guayanilla, Cabo Rojo, and Rio Grande to Luquillo. The number of reported cases has increased at an average rate of 9.6%/yr since 1990. The seasonality of stranding events showed a bimodal pattern, from February through April and in August and September. Most identified causes of death were due to human interaction, especially captures and watercraft collisions. Natural causes usually involved dependent calves. From 1990 through 1995, most deaths were attributed to watercraft collisions. A reduction in anthropogenic mortality of this endangered species can be accomplished only through education and a proactive management and conservation plan that includes law enforcement, mortality assessment, scientific research, rescue and rehabilitation, and inter- and intraagency cooperation.

Increasing prevalence of diagnosed diabetes--United States and Puerto Rico, 1995-2010.

Science.gov (United States)

2012-11-16

In 2010, an estimated 18.8 million persons in the United States had diagnosed diabetes mellitus and another 7.0 million had undiagnosed diabetes. Since 1990, the prevalence of diagnosed diabetes in the United States has risen sharply among all age groups, both sexes, and all racial/ethnic groups for which data are available. To learn whether the increase has been greater in some regions of the United States than in others, data on self-reported diabetes in adults collected during 1995-2010 by the Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. The analysis showed that the age-adjusted prevalence of diagnosed diabetes increased during the interval in every state, the District of Columbia (DC), and Puerto Rico. In 1995, age-adjusted prevalence was ≥6% in only three states, DC, and Puerto Rico, but by 2010 it was ≥6% in every state, DC, and Puerto Rico, and ≥10.0% in six states and Puerto Rico. Strategies to prevent diabetes and its preventable risk factors are needed, especially for those at highest risk for diabetes, to slow the rise in diabetes prevalence across the United States. Continued surveillance of diabetes prevalence and incidence, its risk factors, and prevention efforts is important to measure progress of prevention efforts.

Full Text Available Puerto Rico has been going through a period of economic downturn since 2006, beginning a little before the global economic recession. This paper examines the behavior of loans granted by the commercial banking sector and their relationship with the number of business bankruptcies filed in Puerto Rico between 1999 and 2011. Findings draw attention to the fact that from 2006, there has been a steady decline in the number of personal, commercial and mortgage loans approved by the commercial banking sector, as well as in their value. An increase in the filing of bankruptcy is also observed. The number of loans approved by banks in Puerto Rico show a strong correlation with the economic activity index (EAI and other economic indicators that help to explain the island’s employment situation (total employment, labor force participation rate and unemployment rate.

Post-1898 Imaginative Geographies: Puerto Rico Migration in 1950s Film

Directory of Open Access Journals (Sweden)

Cynthia Tolentino

2011-12-01

Full Text Available This essay studies cultural representations of Puerto Rico’s economic boom and 1952 shift in legal status to the Commonwealth of Puerto Rico. It suggests that apprehending these events requires the reframing of Puerto Rican migration as global phenomena. Drawing on the historical and cultural scholarship on Puerto Rican migration, Operation Bootstrap, and US empire, Tolentino analyzes the famous musical film West Side Story (1961, but also the Hollywood film Sabrina (1954 and Island productions El Otro Camino (The Other Road, 1955 and Maruja (1958. In contrast to prevailing views, she interprets these films as narratives about migration and modernization that engage the discourse of sentimental modernization, the figure of the jíbaro, and the idea of small town Puerto Rico. In so doing, they reveal the global vision at the center of the Operation Bootstrap development plan and Commonwealth formation. The concluding section suggests how the films take up issues in Puerto Rico’s historiography. Rather than merely illuminating a forgotten historical period of 1950s Puerto Rico, the 1950s films negotiate Puerto Rico’s geographical, political, and cultural locations by rethinking institutionalized meanings of 1898 in discourses of Puerto Rico historiography and US empire. Proposing new ways of interpreting the introduction of the Commonwealth in 1952 makes possible the revision of dominant conceptions of 1898 rooted in nation, government, and constitutional law.

Lessons Learned from the Puerto Rico Battery Energy Storage System

Energy Technology Data Exchange (ETDEWEB)

BOYES, JOHN D.; DE ANA, MINDI FARBER; TORRES, WENCESLANO

1999-09-01

The Puerto Rico Electric Power Authority (PREPA) installed a distributed battery energy storage system in 1994 at a substation near San Juan, Puerto Rico. It was patterned after two other large energy storage systems operated by electric utilities in California and Germany. The U.S. Department of Energy (DOE) Energy Storage Systems Program at Sandia National Laboratories has followed the progress of all stages of the project since its inception. It directly supported the critical battery room cooling system design by conducting laboratory thermal testing of a scale model of the battery under simulated operating conditions. The Puerto Rico facility is at present the largest operating battery storage system in the world and is successfully providing frequency control, voltage regulation, and spinning reserve to the Caribbean island. The system further proved its usefulness to the PREPA network in the fall of 1998 in the aftermath of Hurricane Georges. The owner-operator, PREPA, and the architect/engineer, vendors, and contractors learned many valuable lessons during all phases of project development and operation. In documenting these lessons, this report will help PREPA and other utilities in planning to build large energy storage systems.

Full Text Available This paper outlines the characteristics and determinants of Puerto Rican female entrepreneurs in 2007.  This study utilizes data from the Adult Population Survey (APS for 2007 from the Global Entrepreneurship Monitor (GEM Project.  We find that female entrepreneurs in Puerto Rico are most likely sole owners of their business establishment, face many local competitors, and do not generally export their goods or services outside of the Island. The primary motivation for business start-up was business opportunism along with a personal goal of greater independence at the workplace.  Education serves as a fundamental determinant of female entrepreneurship. Este artículo describe las características y determinantes de mujeres empresarias en Puerto Rico para el 2007. El estudio utiliza los datos de la Encuesta de la Población Adulta del Proyecto de Global Entrepreneurship Monitor (GEM, por sus siglas en inglés. Se encontró que las mujeres empresarias en Puerto Rico tienden a ser dueñas únicas de sus negocios, tienen muchos competidores locales, y usualmente no exportan sus bienes o servicios fuera de la Isla. La motivación primaria para empezar el negocio fue tener una oportunidad de negocio junto a una meta personal de mayor independencia en el lugar de trabajo. La educación es un determinante fundamental de ser empresaria en Puerto Rico.

Bacteria, the endoplasmic reticulum and the unfolded protein response: friends or foes?

Science.gov (United States)

Celli, Jean; Tsolis, Renée M

2015-02-01

The unfolded protein response (UPR) is a cytoprotective response that is aimed at restoring cellular homeostasis following physiological stress exerted on the endoplasmic reticulum (ER), which also invokes innate immune signalling in response to invading microorganisms. Although it has been known for some time that the UPR is modulated by various viruses, recent evidence indicates that it also has multiple roles during bacterial infections. In this Review, we describe how bacteria interact with the ER, including how bacteria induce the UPR, how subversion of the UPR promotes bacterial proliferation and how the UPR contributes to innate immune responses against invading bacteria.

The Work of US Public Health Service Officers in Puerto Rico, 1898-1919.

Science.gov (United States)

Rigau-Pérez, Jose G

2017-09-01

The history of the US Public Health Service (PHS) is usually presented in terms of diseases or discoveries; this article examines twenty years' activity in one location. When the United States invaded Puerto Rico in 1898, the Marine Hospital Service (now PHS) took responsibility for foreign quarantine, inspection of immigrants, and medical care for merchant seamen. Its officers evaluated the sanitary conditions of port cities, helped reorganize local disease surveillance and control, and investigated endemic diseases (e.g., hookworm-related anemia) and epidemics (e.g., bubonic plague). After World War I and pandemic influenza, and the greater self-government allowed Puerto Rico by Congress in 1917, PHS officers withdrew from routine local sanitary actions. A narrow geographic focus (Puerto Rico), to examine PHS activity over time (1898 to 1919) provides a richer picture of the agency's impact, and reveals how the sum of disease control activities affected the development of an area's health status and institutions. The duties and, importantly, the personal initiatives of PHS officers in Puerto Rico, such as WW King, produced lasting impact on scientific institutions and administrative, professional, and health care practices.

Emerging Role of the Unfolded Protein Response in Tumor Immunosurveillance.

Vanacker, Hélène; Vetters, Jessica; Moudombi, Lyvia; Caux, Christophe; Janssens, Sophie; Michallet, Marie-Cécile

2017-07-01

Disruption of endoplasmic reticulum (ER) homeostasis results in ER stress and activation of the unfolded protein response (UPR). This response alleviates cell stress, and is activated in both tumor cells and tumor infiltrating immune cells. The UPR plays a dual function in cancer biology, acting as a barrier to tumorigenesis at the premalignant stage, while fostering cancer maintenance in established tumors. In infiltrating immune cells, the UPR has been involved in both immunosurveillance and immunosuppressive functions. This review aims to decipher the role of the UPR at different stages of tumorigenesis and how the UPR shapes the balance between immunosurveillance and immune escape. This knowledge may improve existing UPR-targeted therapies and the design of novel strategies for cancer treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

Stroke is the fifth leading cause of death and the first cause of long-term disability in Puerto Rico. Trained staff reviewed and independently validated the medical records of patients who had been hospitalized with possible stroke at any of the 20 largest hospitals located in Puerto Rico during 2007, 2009, and 2011. The mean age of the 5005 newly diagnosed stroke patients (51·2% female) was 70 years. At the time of hospitalization, women were 4½ years older, were less likely to be married (60·2% vs. 39·9%, P diabetes (56·0% vs. 54·8%), hypertension (89·1% vs. 85·0%), and low density lipoprotein-cholesterol (LDL-Chol) > 100 mg/dL (65·7% vs. 57·5%) P < 0·05. Ischemic stroke represented 75% of all types of strokes. Atrial fibrillation was mentioned in 7·9% of the medical records. The risk for dying before discharge was similar for both genders, but was 40% higher for women than for men at one-year follow-up: age-adjusted odds ratio = 1·4 (95% confidence interval = 1·2-1·5). © 2014 World Stroke Organization.

The Unfolded Protein Response in Amelogenesis and Enamel Pathologies

Full Text Available During the secretory phase of their life-cycle, ameloblasts are highly specialized secretory cells whose role is to elaborate an extracellular matrix that ultimately confers both form and function to dental enamel, the most highly mineralized of all mammalian tissues. In common with many other “professional” secretory cells, ameloblasts employ the unfolded protein response (UPR to help them cope with the large secretory cargo of extracellular matrix proteins transiting their ER (endoplasmic reticulum/Golgi complex and so minimize ER stress. However, the UPR is a double-edged sword, and, in cases where ER stress is severe and prolonged, the UPR switches from pro-survival to pro-apoptotic mode. The purpose of this review is to consider the role of the ameloblast UPR in the biology and pathology of amelogenesis; specifically in respect of amelogenesis imperfecta (AI and fluorosis. Some forms of AI appear to correspond to classic proteopathies, where pathological intra-cellular accumulations of protein tip the UPR toward apoptosis. Fluorosis also involves the UPR and, while not of itself a classic proteopathic disease, shares some common elements through the involvement of the UPR. The possibility of therapeutic intervention by pharmacological modulation of the UPR in AI and fluorosis is also discussed.

Distinct unfolded protein responses mitigate or mediate effects of nonlethal deprivation of C. elegans sleep in different tissues.

Science.gov (United States)

Sanders, Jarred; Scholz, Monika; Merutka, Ilaria; Biron, David

2017-08-28

Disrupting sleep during development leads to lasting deficits in chordates and arthropods. To address lasting impacts of sleep deprivation in Caenorhabditis elegans, we established a nonlethal deprivation protocol. Deprivation triggered protective insulin-like signaling and two unfolded protein responses (UPRs): the mitochondrial (UPR mt ) and the endoplasmic reticulum (UPR ER ) responses. While the latter is known to be triggered by sleep deprivation in rodent and insect brains, the former was not strongly associated with sleep deprivation previously. We show that deprivation results in a feeding defect when the UPR mt is deficient and in UPR ER -dependent germ cell apoptosis. In addition, when the UPR ER is deficient, deprivation causes excess twitching in vulval muscles, mirroring a trend caused by loss of egg-laying command neurons. These data show that nonlethal deprivation of C. elegans sleep causes proteotoxic stress. Unless mitigated, distinct types of deprivation-induced proteotoxicity can lead to anatomically and genetically separable lasting defects. The relative importance of different UPRs post-deprivation likely reflects functional, developmental, and genetic differences between the respective tissues and circuits.

Se trata de un segmento apenas explorado que se aborda desde un marco teórico que estudia la relación entre la identidad nacional y el Otro. La identidad se construye a través de las sucesivas identificaciones "simbólicas e imaginarias" con Otros relevantes. Dichas identificaciones pueden ser tanto positivas como negativas. Para clasificar dichas identificaciones hacia la UE, cualitativamente, se proponen cuatro criterios básicos: "democracia", "economía", "seguridad" e "identidad nacional". Las fuentes utilizadas son los discursos del presidente Václav Klaus y los programas electorales del ODS y KSCM. Una de las conclusiones sugiere que las identifi caciones negativas hacia la UE están asociadas a reminiscencias de relaciones traumáticas con potencias del pasado, como la URSS, Alemania o el imperio Habsburgo.

The Unfolded Protein Response in Chronic Obstructive Pulmonary Disease.

Science.gov (United States)

Kelsen, Steven G

2016-04-01

Accumulation of nonfunctional and potentially cytotoxic, misfolded proteins in chronic obstructive pulmonary disease (COPD) is believed to contribute to lung cell apoptosis, inflammation, and autophagy. Because of its fundamental role as a quality control system in protein metabolism, the "unfolded protein response" (UPR) is of potential importance in the pathogenesis of COPD. The UPR comprises a series of transcriptional, translational, and post-translational processes that decrease protein synthesis while enhancing protein folding capacity and protein degradation. Several studies have suggested that the UPR contributes to lung cell apoptosis and lung inflammation in at least some subjects with human COPD. However, information on the prevalence of the UPR in subjects with COPD, the lung cells that manifest a UPR, and the role of the UPR in the pathogenesis of COPD is extremely limited and requires additional study.

The cell wall and endoplasmic reticulum stress responses are coordinately regulated in Saccharomyces cerevisiae

OpenAIRE

2009-01-01

The unfolded protein response (UPR) is an intracellular signaling pathway that regulates the cellular response to the accumulation of misfolded proteins in eukaryotes. Our group has demonstrated that cell wall stress activates UPR in yeast through signals transmitted by the cell wall integrity (CWI) mitogen-activated protein (MAP) kinase cascade. The UPR is required to maintain cell wall integrity; mutants lacking a functional UPR have defects in cell wall biosynthesis and are hypersensitive ...

Finalizaba el año de 1925 cuando un jurado, reunido en los viejos claustros de Santa Inés, otorgaba a EDMUNDO RICO el grado de Doctor en Medicina y Cirugía. Ese jurado examinador integrado por los profesionales más destacados de la época y presidido por el Profesor José María Lombana Barreneche, estaba constituido por los profesores Carios Esguerra, Roberto Franco, Luis Felipe Calderón y Juan N. Corpas, siendo Secretario de la Facultad el entonces muy joven médico José del Carmen Acosta. Es de anotar que los hombres mencionados llenan todo un periodo médico en 10 que va corrido del presente siglo.

La tesis del graduado versaba sobre la patogenia y tratamiento de la rabia y en ella exhibía ya el novel galeno su estilo inconfundible, por ser tan personal; esa tesis todavía tiene actualidad y en ella se describe, como en una novela de suspenso, la carrera a muerte que se entabla a través del sistema nervioso, entre el virus de la hidrofobia y las antitoxinas
correspondientes, siendo la meta de la carrera los centros nerviosos superiores. No es de extrañar que ya Rico exhibiera veteranía en su amena prosa, si siendo estudiante había escrito numerosas siluetas sobre varios profesores y había colaborado ocasionalmente en la prensa periódica.
Estaba en vigencia en aquéllos tiempos la antigua y gallarda usanza de respetar, acatar y estimar a los profesores de la Facultad. Y en verdad que Rico siempre fue fiel a tal postulado de elemental hidalguía, a pesar de ser un hombre esencialmente irreverente. Eran los tiempos en que a la muerte del Profesor Rivas, su cadáver fue transportado en hombros por sus alumnos reprobados.
Regían por entonces los principios de la medicina francesa, a la sazón a la cabeza de la ciencia universal, y por tanto Rico fue a perfeccionar sus estudios a la antigua Lutecia. Alli al comienzo siguió cursillos de cirugía, abandonándolos prestamente para dedicarse a las ciencias psicol

Researches on Agricultural Cooperative Economic Organization Promoting Agricultural Insurance Development

Institute of Scientific and Technical Information of China (English)

2011-01-01

The advantages of cooperative economic organization being the effective carrier of agricultural insurance development are analyzed. Firstly, cooperative economic organization promotes scale management and solves the problem of decentralized operation of small households. Secondly, cooperative economic organization can settle the problem of peasants’ low systematization. Thirdly, cooperative economic organization can largely reduce the costs of agricultural insurance operation. Fourthly, cooperative organization decreases moral risks as well as adverse selection to some extent. Lastly, cooperative organization, to a certain degree, reduces the risks of agricultural production and increases the insurability of agricultural risks. Meanwhile, limitations of agricultural cooperative economic organization being the carrier of agricultural insurance operation are pointed out. Firstly, cooperative economic organization has limited coverage and small size of organization, which is harmful to the diversification of agricultural risks. Secondly, cooperative economic organization lacks capital funds and its development is not standard, which is not perfect for the function exertion as a carrier. Lastly, members of professional cooperative organization have low cultural qualities, which restrict the implementation of agricultural insurance. The modes of farmers’ cooperative economic organization promoting agricultural insurance development are proposed, including mode of agricultural insurance cooperative ( mutual corporation), mode of "leading enterprises (companies) + professional cooperative organization (planting majors) + insurance" and mode of professional cooperatives serving as agricultural insurance agent. Last of all, the promoting role of agricultural insurance in agricultural cooperative economic organization is briefly illustrated.

Genetic structure of the gentle Africanized honey bee population (gAHB) in Puerto Rico.

The Africanized honey bee is one of the most spectacular invasions in the Americas. African bees escaped from apiaries in Brazil in 1956, spread over Americas and by 1994 they were reported in Puerto Rico. In contrast to other places, the oceanic island conditions in Puerto Rico may mean a single introduction and different dynamics of the resident European and new-coming Africanized bees.To examine the genetic variation of honey bee feral populations and colonies from different locations in Puerto Rico, we used eight known polymorphic microsatellite loci. In Puerto Rico, gAHB population does not show any genetic structure (Fst = 0.0783), and is best described as one honey bee population, product of hybridization of AHB and EHB. The genetic variability in this Africanized population was similar to that reported in studies from Texas. We observed that European private allele frequencies are high in all but one locus. This contrasts with mainland Africanized populations, where European allele frequencies are diminished. Two loci with European private alleles, one on Linkage Group 7, known to carry two known defensiveness Quantitative Trait Loci (QTLs), and the other on Linkage Group 1, known to carry three functionally studied genes and 11 candidate genes associated with Varroa resistance mechanisms were respectively, significantly greater or lower in European allele frequency than the other loci with European private alleles. Genetic structure of Puerto Rico gAHB differs from mainland AHB populations, probably representing evolutionary processes on the island.

Helicobacter pylori is an important etiologic factor for peptic ulcers and gastric cancer, one of the top ten leading causes of cancer death in Puerto Rico. However, the prevalence of H. pylori infections in this population was previously unknown. The aim of this study was to examine the seroprevalence of H. pylori and its associated risk factors in Puerto Rico. A cross-sectional study was designed using an existing population-based biorepository. Seropositivity was determined using the Premier ™ H. pylori immunoassay. Helicobacter pylori seroprevalence was estimated with 95% confidence using marginal standardization following logistic regression. To assess the risk factors associated with H. pylori seropositivity, a multivariable log-binomial model was fitted to estimate the prevalence ratio (PR) and its 95% confidence interval (95% CI). A total of 528 population-based serum samples were analyzed. The mean age of the study population was 41 ± 12 years, of whom 55.3% were females. The overall seroprevalence of H. pylori was 33.0% (95% CI = 28.3%-38.1%). Increasing age and having Puerto Rico. The H. pylori seroprevalence observed in Puerto Rico is similar to the seroprevalence reported in the overall population of the United States. The association between H. pylori seroprevalence and the risk factors analyzed offers insight into the epidemiology of gastric cancer in Puerto Rico and warrants further investigation. © 2017 The Authors.

The Puerto Rico Seismic Network (PRSN) is an integral part of earthquake and tsunami monitoring in Puerto Rico and the Virgin Islands. The PRSN conducts scientific research as part of the University of Puerto Rico Mayaguez, conducts the earthquake monitoring for the region, runs extensive earthquake and tsunami education and outreach programs, and acts as a Tsunami Warning Focal Point Alternate for Puerto Rico. During and in the immediate aftermath of Hurricane Maria, the PRSN duties and responsibilities evolved from a seismic network to a major information and communications center for the western side of Puerto Rico. Hurricane Maria effectively destroyed most communications on island, critically between the eastern side of the island where Puerto Rico's Emergency Management's (PREMA) main office and the National Weather Service (NWS) is based and the western side of the island. Additionally, many local emergency management agencies on the western side of the island lost a satellite based emergency management information system called EMWIN which provides critical tsunami and weather information. PRSN's EMWIN system remained functional and consequently via this system and radio communications PRSN became the only information source for NWS warnings and bulletins, tsunami alerts, and earthquake information for western Puerto Rico. Additionally, given the functional radio and geographic location of the PRSN, the network became a critical communications relay for local emergency management. Here we will present the PRSN response in relation to Hurricane Maria including the activation of the PRSN devolution plan, adoption of duties, experiences and lessons learned for continuity of operations and adoption of responsibilities during future catastrophic events.

2003-01-01

The U.S. Department of Energy (DOE) proposes to consent to a proposal by the Puerto Rico Electric Power Authority (PREPA) to allow public access to the Boiling Nuclear Superheat (BONUS) reactor building located near Rincon, Puerto Rico for use as a museum. PREPA, the owner of the BONUS facility, has determined that the historical significance of this facility, as one of only two reactors of this design ever constructed in the world, warrants preservation in a museum, and that this museum would provide economic benefits to the local community through increased tourism. Therefore, PREPA is proposing development of the BONUS facility as a museum

Duchenne and Becker Muscular Dystrophy (DMD and BMD, respectively), are common forms of inherited muscle disease. Information regarding the epidemiology of these conditions, including genotype, is still sparse. To establish the prevalence and genetic profile of DMD and BMD in Puerto Rico. We collected data from medical records in all Muscular Dystrophy Association (MDA) clinics in Puerto Rico in order to estimate the prevalence of DMD and BMD and to describe the genotypic profile of these patients. Patients selected for data analysis matched "definite", "probable" and "possible" case definitions as established by MD STARnet. A total of 141 patients matched the inclusion criteria, with 64.5% and 35.5% being categorized into DMD and BMD, respectively. DMD and BMD prevalence in Puerto Rico was estimated at 5.18 and 2.84 per 100,000 males, respectively. Deletion was the most common form of mutation (66.7%) in the dystrophin gene, with exons in segment 45 to 47 being the most frequently affected. This is the first report of the prevalence and genetic profile characteristics of DMD and BMD in Puerto Rico. Prevalence of DMD was similar to that reported worldwide, while prevalence of BMD was higher. Genetic profile was consistent with that reported in the literature.

Gómez-Gómez, Fernando; Rodríguez-Martínez, Jesús; Santiago, Marilyn

2014-01-01

The availability of hydrogeologic maps for Puerto Rico and the outlying islands of Vieques, Culebra, and Mona are important to hydrogeologists, groundwater specialists, and water resource managers and planners. These maps, in combination with the report, serve as a source of information to all users by providing basic hydrogeologic and hydrologic knowledge in a concise illustrated format. Puerto Rico and the outlying islands cover a total area of 8,927 square kilometers (km2). Of this total area, about 3,500 km2 are underlain by hydrogeologic units that are classified as intergranular or fissured. These hydrogeologic units form the principal aquifer systems throughout Puerto Rico and the outlying islands. In Puerto Rico, the most extensive and intensely developed aquifers are the North Coast Limestone aquifer system and the South Coastal Alluvial Plain aquifer system. Withdrawals from these two aquifer systems constitute nearly 70 percent of the total groundwater withdrawn in Puerto Rico. The spatial extent of the North Coast Limestone aquifer system is about 2,000 km2. Within this aquifer system, groundwater development is greatest in the 800-km2 area between the Río Grande de Arecibo and the Río de la Plata. This also is the area for which concern is the highest regarding the future use of groundwater as a primary source of water for domestic and industrial use. With an estimated withdrawal of 280,000 cubic meters per day (m3/d), groundwater constituted the principal source of water within this area providing 100 percent of the water for self-supplied industries and about 85 percent for public water supplies in 1985. By 2005, groundwater withdrawals decreased to 150,000 m3/d. The spatial extent of the South Coastal Alluvial Plain aquifer system is about 470 km2. The estimated consumptive groundwater withdrawal from the aquifer system was 190,000 m3/d in 1980 and 170,000 m3/d in 2005. About 60 percent and 40 percent of the groundwater withdrawal from the South

Hepatitis C serosorting among people who inject drugs in rural Puerto Rico.

2017-06-01

Due to the high cost of treatment, preventative measures to limit Hepatitis C (HCV) transmission among people who inject drugs (PWID) are encouraged by many public health officials. A key one of these is serosorting, where PWID select risk partners based on concordant HCV status. Research on the general U.S. population by Smith et al. (2013) found that knowledge of one's own HCV status facilitated serosorting behaviors among PWID, such that respondents with knowledge of their own status were more likely to ask potential partners about their status prior to sharing risk. Our objective was to see if this held true in rural Puerto Rico. We replicate this study using a sample of PWID in rural Puerto Rico to draw comparisons. We used respondent driven sampling to survey 315 participants, and have a final analytic sample of 154. The survey was heavily modeled after the National HIV Behavioral Survey, which was the dataset used by the previous researchers. We found that among PWID in rural Puerto Rico, unlike in the general population, knowledge of one's own HCV status had no significant effect on the selection of one's most recent injection partner, based on his/her HCV status. We conclude that PWID in rural Puerto Rico differ from the general U.S. population when it comes to serosorting behaviors, and that these differences should be taken into account in future outreaches and intervention strategies.

Zika virus infection during pregnancy remains a serious health threat in Puerto Rico. Infection during pregnancy can cause microcephaly, brain abnormalities, and other severe birth defects (1). From January 1, 2016 through March 29, 2017, Puerto Rico reported approximately 3,300 pregnant women with laboratory evidence of possible Zika virus infection (2). There is currently no vaccine or intervention to prevent the adverse effects of Zika virus infection during pregnancy; therefore, prevention has been the focus of public health activities, especially for pregnant women (3). CDC and the Puerto Rico Department of Health analyzed data from the Pregnancy Risk Assessment Monitoring System Zika Postpartum Emergency Response (PRAMS-ZPER) survey conducted from August through December 2016 among Puerto Rico residents with a live birth. Most women (98.1%) reported using at least one measure to avoid mosquitos in their home environment. However, only 45.8% of women reported wearing mosquito repellent daily, and 11.5% reported wearing pants and shirts with long sleeves daily. Approximately one third (38.5%) reported abstaining from sex or using condoms consistently throughout pregnancy. Overall, 76.9% of women reported having been tested for Zika virus by their health care provider during the first or second trimester of pregnancy. These results can be used to assess and refine Zika virus infection prevention messaging and interventions for pregnant women and to reinforce measures to promote prenatal testing for Zika.

Full Text Available Since its inception, the Universal Periodic Review (UPR has been subjected to a substantial amount of criticism. The mechanism began functioning in 2008, however there have been little made known about the roles and functions of the UPR. This article explicitly examines the first UPR process of Malaysia in 2009, in order to illustrate how the mechanism operates in practice by highlighting the engagement of Malaysia government with the stakeholders, the follow-up process and the main issues concerned. This article argues that in spite of the excellent diplomacy skills that portrayed by the Malaysian government in the UPR session, the human rights situation in the country has not been improved much. This paper seeks to determine how effective the UPR has been at encouraging human rights reforms nationally by analyzing and assessing the implementation actions of Malaysian government in response to their accepted UPR recommendations.

Our aim was to examine the association between employment status, depression, drinking, binge drinking, and DSM-5 alcohol use disorder in Puerto Rico. Data are from a 2013 to 2014 household random sample of individuals 18 to 64 years of age in San Juan, Puerto Rico. Bivariate analyses showed that depression was 5 times higher among unemployed males than among those employed full time (21% vs. 4%) and 2 times higher among unemployed females compared to those employed part time or full time (18% vs. 7% and 9%). Employment status was not associated with weekly volume of drinking, but nonparticipation in the workforce was protective against drinking (odds ratio [OR] = 2.17; 95% confidence interval [CI]: 1.03 to 4.57; p gender was a factor of risk for being a current drinker (OR = 2; 95% CI = 1.53 to 2.6; p gender was protective against depression (OR = 0.32; 95% CI = 0.14 to 0.73; p employed only part time were almost 5 times more likely than females employed full time to be depressed (OR = 4.66; 95% CI = 1.25 to 17.38; p Employment status in Puerto Rico is associated with depression and with current drinking, but not with other alcohol-related outcomes. Perhaps Puerto Rico is a "wet" environment, where drinking is already at a relatively high level that is not affected by employment status. Perhaps the chronic high rate of unemployment in the island has also created familial (e.g., support) and personal level accommodations (e.g., participation in the informal economy) that do not include increased drinking.

2015-10-01

The small Indian mongoose (Herpestes auropunctatus) was introduced to several Caribbean Islands to control rat (Rattus spp.) damage to sugarcane plantations. Mongooses failed at suppressing rat populations and are now considered pests throughout most of their introduced range. Importantly, mongooses are rabies reservoirs on several Caribbean Islands. In Puerto Rico, mongooses have been implicated in up to 70% of reported animal rabies cases. There is no rabies vaccination program for wildlife in Puerto Rico, and data on rabies in mongooses are limited. We conducted a serosurvey of mongooses in two different ecologic environments in Puerto Rico: El Yunque National Forest and Cabo Rojo National Wildlife Refuge. We collected 119 serum samples from 112 mongooses, 44 (39.3%) of which were positive for rabies virus-neutralizing antibodies. We also collected oral swabs from 147 mongooses, including 88 from which we also collected serum. No oral swabs were positive for rabies virus RNA. Our data support previous research suggesting rabies virus is circulating within the mongoose population on Puerto Rico.

Cancer is the leading cause of death in Puerto Rico, suggesting a need for improved strategies, programs, and resources devoted to cancer prevention. Enhanced prevention needs in Puerto Rico were initially identified in pilot studies conducted by the Ponce School of Medicine (PSM) in collaboration with the H. Lee Moffitt Cancer Center (MCC). In the current study, we used community engagement to identify specific needs in cancer prevention and education and strategies to create culturally attuned, effective cancer prevention education programs. A total of 37 participants attended a community forum and were assigned to one of three discussion groups: patients/survivors (n = 14); family/caregivers (n = 11); or healthcare providers (n = 12). Most participants were women (73 %), over 35 years of age, and a majority were married (58 %) and had a university education (81 %). The sessions were recorded and transcribed and analyzed for key themes. Participants wanted improved awareness of cancer prevention in Puerto Rico and believed cancer prevention education should start early, ideally in elementary school. Participants also stressed the importance of creating partnerships with private and government agencies to coordinate educational efforts. Suggested strategies included outreach to communities with limited resources, incorporating the testimony of cancer survivors, and utilizing social media to disseminate cancer prevention information.

To estimate the 2009 prevalence of diagnosed diabetes in Puerto Rico among adults ≥ 20 years of age in order to gain a better understanding of its geographic distribution so that policymakers can more efficiently target prevention and control programs. A Bayesian multilevel model was fitted to the combined 2008-2010 Behavioral Risk Factor Surveillance System and 2009 United States Census data to estimate diabetes prevalence for each of the 78 municipios (counties) in Puerto Rico. The mean unadjusted estimate for all counties was 14.3% (range by county, 9.9%-18.0%). The average width of the confidence intervals was 6.2%. Adjusted and unadjusted estimates differed little. These 78 county estimates are higher on average and showed less variability (i.e., had a smaller range) than the previously published estimates of the 2008 diabetes prevalence for all United States counties (mean, 9.9%; range, 3.0%-18.2%).

This paper presents the data sources and methodology used to estimate Green Net National Product (GNNP), an economic metric of sustainability, for Puerto Rico. Using the change in GNNP as a one-sided test of weak sustainability (i.e., positive growth in GNNP is not enough to show the economy is sustainable), we measure the movement away from sustainability by examining the change in GNNP from 1993 to 2009. In order to calculate GNNP, we require both economic and natural capital data, but limited data for Puerto Rico require a number of simplifying assumptions. Based on the environmental challenges faced by Puerto Rico, we include damages from air emissions and solid waste, the storm protection value of mangroves and the value of extracting crushed stone as components in the depreciation of natural capital. Our estimate of GNNP also includes the value of time, which captures the effects of technological progress. The results show that GNNP had an increasing trend over the 17 years studied with two periods of negative growth (2004-2006 and 2007-2008). Our additional analysis suggests that the negative growth in 2004-2006 was possibly due to a temporary economic downturn. However, the negative growth in 2007-2008 was likely from the decline in the value of time, suggesting the island of Puerto Rico was moving away from sustainability during this time.

2012-12-01

With a population of 4 million, Puerto Rico will be celebrating this year, for first time, an Island-wide earthquake drill following the Great California ShakeOut model. Most of our population has never experienced a large earthquake, since our last significant event occurred on 1918, and is not adequately prepared to respond to a sudden ground movement. During the moderate-size earthquakes (M5.2-5.8) that have been felt in Puerto Rico since 2010, and despite Puerto Rico Seismic Network education efforts, the general public reaction was inappropriate, occasionally putting themselves and others at risk. Our overarching goal for the Great Puerto Rico ShakeOut is to help develop seismic awareness and preparedness in our communities. In addition, our main objectives include: to teach the public to remain calm and act quickly and appropriately during a seismic event, the identification and correction of potential hazards that may cause injuries, and the development/update of mitigation plans for home, work place and/or school. We are also taking this opportunity to clarify the misconceptions of other methods of protection (e.g. triangle of life) and warning equipment and systems that do not have sound scientific or applicable basis for our country. We will be presenting an overview of the accomplishment of our earthquake drill and the different strategies we are using, such as internet, social media and collaboration with state government agencies and professional groups, to reach diverse age and educational level groups and to promote their participation. One of our main target groups this year are school students since their experience can have a direct and positive impact on their families. The drill webpage was developed in Spanish and English as well as our promotional and educational materials. Being the first time a Spanish-speaking country coordinates a ShakeOut exercise we hope our experience and the materials we are developing could be of use and benefit to

Since the beginning of the 2000s, it has been conducted many projects such as Agricultural Sector Integrated Management Information System, Agriculture Information System, Agricultural Production Registry System and Farmer Registry System by the Turkish Ministry of Food, Agriculture and Livestock and the Turkish Statistical Institute in order to establish and manage better agricultural policy and produce better agricultural statistics in Turkey. Yet, it has not been carried out any study for the structuring of a system which can meet the requirements of different institutions and organizations that need similar agricultural data. It has been tried to meet required data only within the frame of the legal regulations from present systems. Whereas the developments in GIS (Geographical Information Systems) and standardization, and Turkey National GIS enterprise in this context necessitate to meet the demands of organizations that use the similar data commonly and to act in terms of a data model logic. In this study, 38 institutions or organization which produce and use agricultural data were detected, that and thanks to survey and interviews undertaken, their needs were tried to be determined. In this study which is financially supported by TUBITAK, it was worked out relationship between farmer, agricultural land and agricultural production data and all of the institutions and organizations in Turkey and in this context, it was worked upon the best detailed and effective possible data model. In the model design, UML which provides object-oriented design was used. In the data model, for the management of spatial data, sub-parcel data model was used. Thanks to this data model, declared and undeclared areas can be detected spatially, and thus declarations can be associated to sub-parcels. Within this framework, it will be able to developed agricultural policies as a result of acquiring more extensive, accurate, spatially manageable and easily updatable farmer and

1999-10-01

On 7 January 1994, the barge Morris J. Berman spilled approximately 3.6 million liters of oil off Punta Escambron in San Juan, Puerto Rico. This resulted in the contamination of extensive areas, impacting on natural resources along more than 48 km of Puerto Rico`s north shore. Thousands of dead and alive oiled organisms washed ashore. Dead wildlife were collected opportunistically, and examined for the presence of oil and identified. Live wildlife was cleaned and treated at a temporary triage facility. A total of 5687 organisms of over 152 species were collected, including cnidarians, annelids, crustaceans, molluscs, echinoderms, fishes, birds and sea turtles. Molluscs and echinoderms were noticeably more affected than other species. Four species classified as endangered or threatened were also affected. A significant impact was observed on the live specimens presented for medical treatment, including shore crabs, birds and sea turtles. Only 63% of these were successfully rehabilitated. (author)

Hepatocellular carcinoma (HCC) responds poorly to conventional systemic therapies. The first-in-class proteasome inhibitor bortezomib has been approved in clinical use for hematologic malignancies and has shown modest activity in solid tumors, including HCC. However, a considerable proportion of patients fail to respond and experience important adverse events. Recently, the next-generation orally bioavailable irreversible proteasome inhibitor oprozomib was developed. Here, we assessed the efficacy of oprozomib and its effects on the unfolded protein response (UPR), a signaling cascade activated through the ATF6, PERK and IRE1 pathways by accumulation of unfolded proteins in the endoplasmic reticulum, in HCC. The effects of oprozomib and the role of the UPR were evaluated in HCC cell lines and in diethylnitrosamine-induced and xenograft mouse models for HCC. Oprozomib dose-dependently reduced the viability and proliferation of human HCC cells. Unexpectedly, oprozomib-treated cells displayed diminished cytoprotective ATF6-mediated signal transduction as well as unaltered PERK and IRE1 signaling. However, oprozomib increased pro-apoptotic UPR-mediated protein levels by prolonging their half-life, implying that the proteasome acts as a negative UPR regulator. Supplementary boosting of UPR activity synergistically improved the sensitivity to oprozomib via the PERK pathway. Oral oprozomib displayed significant antitumor effects in the orthotopic and xenograft models for HCC, and importantly, combining oprozomib with different UPR activators enhanced the antitumor efficacy by stimulating UPR-induced apoptosis without cumulative toxicity. In conclusion, next-generation proteasome inhibition by oprozomib results in dysregulated UPR activation in HCC. This finding can be exploited to enhance the antitumor efficacy by combining oprozomib with clinically applicable UPR activators.

AGRICULTURE AND AGRICULTURAL COOPERATIVES IN JAPAN - A MODEL FOR COOPERATIVIZATION OF AGRICULTURE FROM ROMANIA

Directory of Open Access Journals (Sweden)

Remus Gherman

2016-10-01

Full Text Available Japan's agriculture provides only a part from the population's needs, in caloric terms Japan must impute 60% of foods. Arable land are few, but are worked very performant, rice being the main crop together with cotton, citrus, sugarcane, wheat, potato, soybean, sugar beet, other vegetables. Widely is practiced sericulture and fisheries, Japan being one of the leading producers of silk from the world and having over 600 ports specialized for fishing. Japanese agriculture has remained behind the industry and services, this trend being manifested after the very high economic growth from 1960-1970. The main focus of the movements from the Japanese cooperative system is represented by the creation of large specialized farms through the replacing of the traditional ones. The most important task of agricultural cooperatives from Japan is meeting the consumption needs of its members. Integrated leadership of Japanese cooperatives of farmers act at all levels, primary, at prefecture level and at national level. Contractual relationships play a decisive role in the integration of Japanese farmers. In Japan there are about 840 agricultural cooperatives very well organized with a balanced planning and efficiently conducted, agricultural cooperative MIKABI being the most developed, mainly focused on the production of mandarins. In Japan there are three large distribution centers of agricultural products, 29 distribution markets controlled by the prefecture and 1,000 local markets. Organization of cooperatives is the pyramid system on three levels: local, prefecture and national (National Federation of Agricultural Cooperatives.

As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

Estimated water use in Puerto Rico, 2010

Science.gov (United States)

Molina-Rivera, Wanda L.

2014-01-01

Water-use data were aggregated for the 78 municipios of the Commonwealth of Puerto Rico for 2010. Five major offstream categories were considered: public-supply water withdrawals and deliveries, domestic and industrial self-supplied water use, crop-irrigation water use, and thermoelectric-power freshwater use. One instream water-use category also was compiled: power-generation instream water use (thermoelectric saline withdrawals and hydroelectric power). Freshwater withdrawals for offstream use from surface-water [606 million gallons per day (Mgal/d)] and groundwater (118 Mgal/d) sources in Puerto Rico were estimated at 724 million gallons per day. The largest amount of freshwater withdrawn was by public-supply water facilities estimated at 677 Mgal/d. Public-supply domestic water use was estimated at 206 Mgal/d. Fresh groundwater withdrawals by domestic self-supplied users were estimated at 2.41 Mgal/d. Industrial self-supplied withdrawals were estimated at 4.30 Mgal/d. Withdrawals for crop irrigation purposes were estimated at 38.2 Mgal/d, or approximately 5 percent of all offstream freshwater withdrawals. Instream freshwater withdrawals by hydroelectric facilities were estimated at 556 Mgal/d and saline instream surface-water withdrawals for cooling purposes by thermoelectric-power facilities was estimated at 2,262 Mgal/d.

A new paradigm: innate immune sensing of viruses via the Unfolded Protein Response

Directory of Open Access Journals (Sweden)

Judith A Smith

2014-05-01

Full Text Available The immune system depends upon combinations of signals to mount appropriate responses: pathogen specific signals in the context of co-stimulatory danger signals drive immune strength and accuracy. Viral infections trigger anti-viral type I interferon (IFN responses by stimulating endosomal and cytosolic pattern recognition receptors (PRRs. However, viruses have also evolved many strategies to counteract IFN responses. Are there intracellular danger signals that enhance immune responses to viruses? During infection, viruses place a heavy demand on the protein folding machinery of the host endoplasmic reticulum (ER. To survive ER stress, host cells mount an Unfolded Protein Response (UPR to decrease ER protein load and enhance protein-folding capacity. Viruses also directly elicit the UPR to enhance their replication. Increasing evidence supports an intersection between the host UPR and inflammation, in particular the production of pro-inflammatory cytokines and type I IFN. The UPR directly activates pro-inflammatory cytokine transcription factors and dramatically enhances cytokine production in response to viral PRR engagement. Additionally, viral PRR engagement may stimulate specific pathways within the UPR to enhance cytokine production. Through these mechanisms, viral detection via the UPR and inflammatory cytokine production are intertwined. Consequently, the UPR response is perfectly poised to act as an infection-triggered danger signal. The UPR may serve as an internal co-stimulatory signal that 1 provides specificity and 2 critically augments responses to overcome viral subterfuge. Further work is needed to test this hypothesis during viral infections.

Full Text Available Financial institutions present on the market become more attentive when they have to give loans to the agriculture sector. The lack of necessary guarantees the low profit registered in agricultural district, economy instability and other things had and continue to have a negative impact on the evolution of agricultural sector, this being seen as one with a high level of risk. Commercial banks use less own funds for lending to agriculture and especially when the loans are guaranteed from various funds, programs or foreign donor agencies. Farmers find it difficult to bank loans because of collateral amount required is too high. However, commercial banks in Moldova provide agricultural loans, thus increasing the economic efficiency of agriculture.

Full Text Available OBJECTIVE: To estimate the 2009 prevalence of diagnosed diabetes in Puerto Rico among adults ≥ 20 years of age in order to gain a better understanding of its geographic distribution so that policymakers can more efficiently target prevention and control programs. METHODS: A Bayesian multilevel model was fitted to the combined 2008-2010 Behavioral Risk Factor Surveillance System and 2009 United States Census data to estimate diabetes prevalence for each of the 78 municipios (counties in Puerto Rico. RESULTS: The mean unadjusted estimate for all counties was 14.3% (range by county, 9.9%-18.0%. The average width of the confidence intervals was 6.2%. Adjusted and unadjusted estimates differed little. CONCLUSIONS: These 78 county estimates are higher on average and showed less variability (i.e., had a smaller range than the previously published estimates of the 2008 diabetes prevalence for all United States counties (mean, 9.9%; range, 3.0%-18.2%.

2007-01-01

Non-indigenous invasive mole crickets, Scapteriscus vicinus Scudder (Orthoptera: Gryllotalpidae) in Florida and S. didactylus (Latreille) (the 'changa') in Puerto Rico, are being managed with an entomopathogenic nematode, Steinernema scapterisci (Nguyen and Smart) (Rhabditida: Steinernematidae), and a parasitic wasp, Larra bicolor L. (Hymenoptera: Sphecidae). Pest mole cricket populations have declined by 95% in north central Florida since these specialist natural enemies were released and established in the 1980s. Commercial production of the nematode was initiated, nearly 70 billion were applied in 34 Florida counties, and their establishment, spread, and impact on mole crickets were monitored. The infected mole crickets dispersed the nematode rapidly, so that within 6 months these parasites were present in most of the insects trapped in experimental pastures. Three years later, mole cricket populations were reduced to acceptable levels and the bahiagrass had recovered. The nematode was released for the first time in Puerto Rico during 2001 and has persisted; the wasp was introduced in the late 1930s. The geographical distribution of the wasp is being expanded in Florida and Puerto Rico by planting plots of Spermacoce verticillata (L.), a wildflower indigenous to Puerto Rico and widely distributed in southern Florida. Pastures, sod farms, golf courses, landscapes, and vegetable farms in Florida and Puerto Rico are benefiting from biological control of invasive mole crickets. (author) [es

2016-05-01

Full Text Available Background & Aims: Netrin-1, a multifunctional secreted protein, is up-regulated in cancer and inflammation. Netrin-1 blocks apoptosis induced by the prototypical dependence receptors deleted in colorectal carcinoma and uncoordinated phenotype-5. Although the unfolded protein response (UPR triggers apoptosis on exposure to stress, it first attempts to restore endoplasmic reticulum homeostasis to foster cell survival. Importantly, UPR is implicated in chronic liver conditions including hepatic oncogenesis. Netrin-1's implication in cell survival on UPR in this context is unknown. Methods: Isolation of translational complexes, determination of RNA secondary structures by selective 2’-hydroxyl acylation and primer extension/dimethyl sulfate, bicistronic constructs, as well as conventional cell biology and biochemistry approaches were used on in vitro–grown hepatocytic cells, wild-type, and netrin-1 transgenic mice. Results: HepaRG cells constitute a bona fide model for UPR studies in vitro through adequate activation of the 3 sensors of the UPR (protein kinase RNA–like endoplasmic reticulum kinase (PERK, inositol requiring enzyme 1α (IRE1α, and activated transcription factor 6 (ATF6. The netrin-1 messenger RNA 5'-end was shown to fold into a complex double pseudoknot and bear E-loop motifs, both of which are representative hallmarks of related internal ribosome entry site regions. Cap-independent translation of netrin 5' untranslated region–driven luciferase was observed on UPR in vitro. Unlike several structurally related oncogenic transcripts (l-myc, c-myc, c-myb, netrin-1 messenger RNA was selected for translation during UPR both in human hepatocytes and in mice livers. Depletion of netrin-1 during UPR induces apoptosis, leading to cell death through an uncoordinated phenotype-5A/C–mediated involvement of protein phosphatase 2A and death-associated protein kinase 1 in vitro and in netrin

Full Text Available OBJECTIVE: In spite of long-term endemicity and repeated government and private efforts, effective, sustained community participation for dengue prevention remains a challenge in Puerto Rico. This study explored differences found in interviews conducted in 2001 in attitudes toward dengue and its prevention by respondents' gender and whether they had a prior dengue infection. Findings may be used to develop messages to promote Aedes aegypti control practices. METHODS: From September to October 2003, 11 focus groups were conducted in San Juan, Puerto Rico. Fifty-nine persons (35 women, 24 men, > 18 years of age, who had been identified through the Puerto Rico dengue surveillance system participated in the focus groups. Analysis was based on grounded theory. RESULTS: Women considered dengue important because of its economic, emotional, and health impact, and they were concerned more often than men about insufficient garbage removal and water disposal. Participants with a previous dengue diagnosis were more concerned about risk of the disease, were more knowledgeable about dengue and its prevention, and recommended use of repellents more often than their counterparts without a previous dengue diagnosis. Barriers to sustained dengue prevention included misconceptions from outdated educational materials, " invisibility" of dengue compared with chronic diseases, and lack of acceptance of responsibility for dengue prevention. CONCLUSION: Suggested strategies to motivate residents' actions included working with government agencies to address structural problems that increase mosquito populations, improving access to information on garbage collection and water disposal through telephone hotlines, increasing publicity and information about dengue by mass media campaigns, and educating health professionals.OBJETIVO: A pesar de la prolongada endemia y los reiterados esfuerzos gubernamentales y privados, la participación efectiva y sostenida de la comunidad

New records of parasites for culture Cobia, Rachycentron canadum (Perciformes: Rachycentridae in Puerto Rico

Directory of Open Access Journals (Sweden)

2006-12-01

Full Text Available Intensive aquaculture sometimes provides conditions favorable for parasites that are not ordinarily found on culture fishes in the wild, and the use of introduced stocks sometimes introduces non-indigenous species to the habitat. When officially asked about the culture of Cobia Rachycentron canadum (Linnaeus in Puerto Rico, the authors responded that it was unlikely to cause harm. It was assumed that a well-known culture facility in Florida would assure parasite-free stocks. Subsequent examinations of stocked juveniles surprisingly found parasites new to this fish. An outbreak of Slime-blotch disease, Brooklynella hostilis Lom & Nigrilli, 1970 (Dysteriida: Hartmannulidae occurred in juvenile Cobia after they were shipped from Florida and stocked. This apparently represents a local parasite that took advantage of the weakened and/or crowded fish. The universal aquarium and culture superparasite, Marine Ich, Cryptocaryon irritans Brown, 1951 (Colpodia: Ichthyophthiriidae was introduced with a shipment of juvenile Cobia from Florida. This may not be serious, since the parasite occurs worldwide, unless it represents a new strain to Puerto Rico. Marine Costia, Ichthyobodo sp. (Kinetoplastida: Bodonidae was introduced into Puerto Rico with juvenile Cobia shipped from Florida. This parasite has caused some severe problems in aquaculture hatcheries in Hawaii and Texas after it was introduced with cultured organisms. Thus far, it has not caused any problems locally, but Puerto Rico lacks the marine hatchery facilities where such outbreaks would occur. The question of whether it is established locally will have to wait the development of similar facilities in Puerto Rico. These three species of parasites represent new host records for Cobia. The non-indigenous Ichthyobodo sp. represents new locality records for the tropical Atlantic, Caribbean, and Florida and Puerto Rico. Cobia mature more quickly in culture than in the wild and thus female Cobia

Full Text Available OBJECTIVE: To raise awareness of the impact of homicides in Puerto Rico based on the findings of the spatial and temporal distribution of homicides and the use of firearms, by age and gender, using reports of interpersonal violent deaths from the Institute of Forensic Science (IFS headquartered in San Juan, Puerto Rico. METHODS: This was a descriptive study of all homicide incidents in Puerto Rico reported by the IFS for the period 2001-2010. For each of the 8 542 cases, data analyzed included age, sex, municipality of incident, date of death, and mechanism. Crude sex- and age-specific mortality rates for Puerto Rico and for each municipality per year and for the 10-year period were calculated. Cumulative rate and cumulative risks were estimated and defined as lifetime risk. The relative distribution of cumulative rates for each municipality was categorized into quartiles of highest to lowest risk and displayed as a map. RESULTS: The risk of homicide death among males is 13 times greater than among females. The highest rates were observed among males 20-24 years of age (198.4 homicides per 100 000. In any given year, firearms were used in at least 80% of homicides. The average lifetime risk of homicide death for males is 1 in 34. CONCLUSIONS: Young adult males with access to firearms are at greatest risk of homicide in Puerto Rico. Also, highly urbanized municipalities are at highest risk; however, certain non-urban municipalities along the coast also have a very high homicide risk. Top priorities should be applying the WHO "ecological model" for violent injury prevention and establishing a surveillance system that will assist in identifying the role that socioeconomics, illegal firearms trade, and drug trafficking are playing.OBJETIVO: Concientizar sobre la repercusión de los homicidios en Puerto Rico con base en los resultados de la distribución espacial y temporal de los homicidios y el uso de las armas de fuego, según la edad y el sexo, a

Full Text Available The purpose of this paper is to explain a the historical, organizational, and legislative efforts that have contributed to the development of the Rehabilitation Counseling profession, b how these efforts have contributed to the development of the professional identity of the rehabilitation counselors and c how these events have contributed to the development of programs and the provision of quality services to people with special needs in Puerto Rico. Through oral history and literature review, it is possible to recognize the importance of the establishment of the federal legislation that promoted the first program of services to people with special needs in the United States and Puerto Rico. Those legislative mandates have also promoted the development of the Rehabilitation Counseling profession in the 20th Century and the development of professional organizations that have been determinant for the professionalization. This paper illustrates how at the end of 1960, in Puerto Rico, the creation of the Rehabilitation Counselors Association (Asociación de Consejeros en Rehabilitación, ACER by its Spanish acronym was critical for the transformation of the profession and for the creation of the Puerto Rico’s Professional Society of Rehabilitation Counselors (Colegio Profesional de los Consejeros en Rehabilitación de Puerto Rico at the beginning of the 21st Century. The study refers to the subsequent legislative efforts and the approval of new mandates as the amendment to the Puerto Rican Law of Mental Health made to include the Rehabilitation Counseling professionals among the professionals authorized to provide such services to people with mental health conditions in the country. After this theoretical historical review, it is concluded that although more marketing is required in terms of promoting the profession, this innovative profession has kept up-to-date over time, and that is a guarantee of the professional commitment to continue

The Tropical Agro-Sciences Division has two functions: conduct research on the impact of air pollution on tropical agricultural and to provide training to UPR graduate students and visiting scientists. Since the reorientation of the Center's interests under ERDA, the Division has directed its research activities, with particular emphasis on the effects of atmospheric pollution on tropical agriculture in the Guayanilla-Penuelas region, which has a fossil-fuel power plant, petroleum refineries, and associated industries. This new area of research is important to ERDA because the knowledge gained regarding the effects of air pollution related to energy technology on the agricultural environment and productivity will be useful in planning future energy developments. Information about the potential harm of air pollutants to man through the food chain and about ways of alleviating their impact on agriculture are of practical importance. Studies of the mechanisms involved in pollution injury, protection, and tolerance are of basic significance

Anthropogenic effects including river regulation, watershed development, contamination, and fish introductions have substantially affected the majority of freshwater habitats in Europe and North America. This pattern of resource development and degradation is widespread in the tropics, and often little is known about the resources before they are lost. This article describes the freshwater resources of Puerto Rico and identifies factors that threaten conservation of native fishes. The fishes found in freshwater habitats of Puerto Rico represent a moderately diverse assemblage composed of 14 orders, 29 families, and 82 species. There are fewer than 10 species of native peripherally-freshwater fish that require a link to marine systems. Introductions of nonindigenous species have greatly expanded fish diversity in freshwater systems, and native estuarine and marine species (18 families) also commonly enter lowland rivers and brackish lagoons. Environmental alterations, including land use and development, stream channelization, pollution, and the impoundment of rivers, combined with nonnative species introductions threaten the health and sustainability of aquatic resources in Puerto Rico. Six principal areas for attention that are important influences on the current and future status of the freshwater fish resources of Puerto Rico are identified and discussed.

The Puerto Rico and the Virgin Island microplate is located in at the northeastern corner of the Caribbean plate boundary with North America is placed within an oblique subduction zone in which strain patterns remain unresolved. Seismic hazard is a major concern in the region as seen from the seismic history of the Caribbean-North America plate boundary zone. Most of the tectonic models of the microplate show the accommodation of strain occurring offshore, despite evidence from seismic activity, trench studies, and geodetic studies suggesting the existence of strain accomodation in southwest Puerto Rico. These studies also suggest active faulting specially in the western part of the island, but limited work has been done regarding their mechanism. Therefore, this work aims to define and map these active faults in western Puerto Rico by integrating data from analysis of fluvial terrains, and detailed mapping using digital elevation model (DEM) extracted from Shuttle Radar Topography Mission (SRTM) and LIDAR data. The goal is to (1) identify structural features such as surface lineaments and fault scarps for the Cerro Goden fault, South Lajas fault, and other active faults in the western of Puerto Rico, (2) correlate these information with the distribution pattern and values of the geomorphic proxies, including Chi integral (χ), normalized steepness (ksn) and Asymmetric factor (AF). Our preliminary results from geomorphic proxies and Lidar data provide some insight of the displacement and stage of activities of these faults (e.g. Boqueron-Punta Malva Fault and Cerro Goden fault). Also, the anomaly of the geomorphic proxies generally correlate with the locations of the landslides in the southwestern Puerto Rico. The geomorphic model of this work include new information of active faulting fundamental to produce better seismic hazards maps. Additionally, active tectonics studies are vital to issue and adjust construction buildings codes and zonification codes.

Full Text Available The replication of coronavirus, a family of important animal and human pathogens, is closely associated with the cellular membrane compartments, especially the endoplasmic reticulum (ER. Coronavirus infection of cultured cells was previously shown to cause ER stress and induce the unfolded protein response (UPR, a process that aims to restore the ER homeostasis by global translation shutdown and increasing the ER folding capacity. However under prolonged ER stress, UPR can also induce apoptotic cell death. Accumulating evidence from recent studies has shown that induction of ER stress and UPR may constitute a major aspect of coronavirus-host interaction. Activation of the three branches of UPR modulates a wide variety of signaling pathways, such as mitogen-activated protein (MAP kinases activation, autophagy, apoptosis and innate immune response. ER stress and UPR activation may therefore contribute significantly to the viral replication and pathogenesis during coronavirus infection. In this review, we summarize current knowledge on coronavirus-induced ER stress and UPR activation, with emphasis on their cross-talking to apoptotic signaling.

Este artículo es parte del trabajo que se realiza para trazar el marco teórico de un proyecto de extensión para la Universidad Nacional, denominado “Olimpiadas de la Inteligencia Emocional”. En ese mismo ámbito, se reflexiona sobre la orientación teórica de otros estudios latinoamericanos y su validez.

El Modelo Histórico-narrativo, una propuesta para estudiar el riesgo en salud

Directory of Open Access Journals (Sweden)

Yesica Yolanda Rangel Flores

2014-06-01

Full Text Available El riesgo se ha posicionado históricamente como objeto de estudio en el ámbito sanitario, predominando enfoques teóricos y metodológicos que en el afán de medir aritméticamente el riesgo, dejan de analizar las condiciones socioculturales y políticas que prevalecen en los contextos, así como las relaciones de poder que generan desigualdad e inequidad social y potencian las vulnerabilidades. El objetivo de este artículo es exponer el "Modelo teórico histórico-narrativo" como un marco que posibilita asir el riesgo en la complejidad social en la que los individuos se desempeñan y en dicho sentido, comprender la compleja respuesta social que los sujetos entablan con las amenazas de sus contextos, algunas ocasiones manteniendo un sentido de inmunidad subjetiva frente a las enfermedades, otras tantas asumiéndose vulnerables o construyendo estigmas respecto a particulares tipos de padecimiento.

Energy Colonialism Powers the Ongoing Unnatural Disaster in Puerto Rico

2018-01-01

Full Text Available On September 20, 2017, Hurricane María made landfall in Puerto Rico. Blasting the Caribbean archipelago with 155-mile/h winds, this, in many ways, unnatural disaster exposed the brutal consequences of energy colonialism and an extractivist economy, as well as ongoing and increasing advocacy for decentralized solar infrastructure by many local residents and other renewables supporters. This paper argues that acknowledging colonial power relations and their consequences is essential for studying the interplay of energy systems, environments, and actors. To support this claim, this essay outlines Puerto Rico’s history as a US colony by focusing on key policies and their implications; examines openings for and barriers to decentralized, community solar in Puerto Rico; and concludes by discussing future research directions on just energy transitions and the imperative of uprooting colonialism and agitating for community self-determination and energy justice in these transformations.

Agricultural Multifunctionality Evolution and Research into Issues concerning Agriculture,Countryside and Farmers

From the point of view of agricultural civilization, the history of human civilization is the history of the development of the agricultural civilization. Accompanied by social progress and development of the times, the function of agriculture also experiences the expansion and deepening. In terms of economy, there is a process from mechanized farming to industrialization, then to informatization, modernization and internationalization. The great rejuvenation of the Chinese nation has also experienced and witnessed this process. In terms of "agriculture, countryside and farmers", the content is complex, diverse, profound, sharp, and changing, constantly testing and challenging our wisdom. When the Document No.1 in 2007 targeted modern agriculture, it indicated that new connotation was integrated into agricultural multifunctionality, standing at a new starting point. At present, the function of agriculture is still deepening; there are tremendous achievements and outstanding problems concurrently in issues concerning agriculture, countryside and farmers. We take the agricultural multifunctionality as breakthrough point for exploration and research.

Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

Lago La Plata dam is located between the municipalities of Naranjito and Toa Alta in north central Puerto Rico, about 5 kilometers south of the town of Toa Alta and about 5 kilometers north of the town of Naranjito. The reservoir impounds the waters of the Rio de La Plata, the Rio Guadiana, and the Rio Ca?as, and is part of the San Juan Metropolitan Water District, which provides about 35 percent of the total water demand for the area (Soler-Lopez and others, 2000). The reservoir has a drainage area of about 469 square kilometers. The dam was constructed in 1974 and is a concrete gravity structure with a normal pool elevation of 52.00 meters above mean sea level (Puerto Rico Electric Power Authority, 1979). During October 1998, the U.S. Geological Survey (USGS), Caribbean Water Science Center, in cooperation with the Puerto Rico Aqueduct and Sewer Authority (PRASA) conducted a bathymetric survey of Lago La Plata to assess the impact of Hurricane Georges on the storage capacity of the reservoir. Between July 17 and 20, 2006, the USGS and the PRASA conducted an additional bathymetric survey of Lago La Plata to update the reservoir storage capacity and determine the reservoir sedimentation rate by comparing the 2006 survey data with the 1998 survey data.. The purpose of this report is to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 1998. Historical (1974) data are referenced as needed to account for long-term storage capacity loss trends...

Environmental policy and industrialization: The politics of regulation in Puerto Rico

International Nuclear Information System (INIS)

Concepcion, C.M.

1990-01-01

The effects of economic development on environmental regulation in Puerto Rico are examined. In particular, the research analyzes how the Puerto Rican industrialization process has affected implementation of the environmental-review process. Puerto Rico exemplifies an acute conflict between an industrialization process based on capital-intensive, highly polluting industries, and a regulatory framework of insular and US environmental laws and regulations. While industrialization has not solved unemployment problems on the island, environmental and health hazards have increased significantly, despite environmental regulations. The study focuses on a change in the environmental review process in response to economic development concerns. In particular, it examines the growth and extensive use of a new environmental review document, the Environmental Assessment. This study explains this policy shift and, more fundamentally, analyzes how and under what circumstances this change came about

Jobin, William R.; Ferguson, Frederick F.; Palmer, Juan R.

1970-01-01

In 1953, a programme to control schistosomiasis mansoni was started in Guayama and Arroyo, Puerto Rico, employing, first, chemical and, later, both biological and chemical methods to control Biomphalaria glabrata, the snail host of Schistosoma mansoni. Sodium pentachlorophenate was the molluscicide, and an ampullarid snail, Marisa cornuarietis, was used for biological control in ponds and reservoirs. In addition some chemotherapy was given to infected persons. The prevalence of intestinal schistosomiasis was measured annually, sampling about one-third of the 6-year-old population in Guayama and Arroyo and in Caguas, an untreated area. Costs of the programme and the results are discussed in relation to similar projects in other parts of Puerto Rico. In Guayama and Arroyo the prevalence of schistosomiasis reached zero in 6-year-olds by 1966 despite the persistence of the disease in a nearby untreated area. Although this decline appeared related to the control effort, it is noted that a large decline also occurred in the untreated area, suggesting the influence of other factors such as economic development or improvements in sanitation.

Violence is a public health concern faced on a daily basis by transgender women. Literature has documented how it adversely affects quality of life and health and in some instances leads to homicide. Considering the lack of research documenting the experiences of violence among transgender women, the objective of this article was to explore manifestations of violence among this population in Puerto Rico. The data presented in this article are part of a larger study on transgender/transsexual health in Puerto Rico. For the purpose of this article we focus on the quantitative data analysis. Participants (N = 59 transgender women) were recruited via respondent driven sampling. Implications and specific recommendations are discussed in light of these findings.

Using pesticides has double effects. On one hand, it contributes to pests control and regulates the growth of crops; On the other hand, it does harm to the environment. To develop ecological agriculture should not only emphasize the output level of agriculture to pursuit of economic efficiency, but also need to keep the ecological environment protected and focus on the social benefits during the development of the industry. As a large agricultural country in the world, China is vigorously promoting the development of ecological agriculture, which is bound to put forward to developing the pesticide industry and green ecological development requirements to promote the transformation and upgrading of agricultural pharmaceutical industry. This paper discusses the mechanism of pesticide pollution on the ecological environment and analyzes China's agricultural problems in the pharmaceutical industry. Then study on the development of Chinese green pesticides and try to find the proper paths of agricultural pharmaceutical to achieve industrial upgrading.

Burrows, Nilka Rios; Hora, Israel; Williams, Desmond E; Geiss, Linda S

2014-03-07

During 2010, approximately 6,091 persons aged ≥18 years in Puerto Rico were living with end-stage renal disease (ESRD) (i.e., kidney failure that requires regular dialysis or kidney transplantation for survival). This included 1,462 persons who began treatment for ESRD in 2010. Diabetes is the leading cause of ESRD in Puerto Rico, accounting for 66% of new cases in adults, followed by hypertension, which accounts for 15% of the cases. Although the number of adults initiating ESRD treatment (i.e., dialysis or kidney transplantation) in Puerto Rico each year who have diabetes listed as a primary cause (ESRD-D) has increased since 1996, ESRD-D incidence among adults with diagnosed diabetes has not shown a consistent trend. To assess recent trends in ESRD-D incidence among adults aged ≥18 years in Puerto Rico with diagnosed diabetes and to further examine trends by age group and sex, CDC analyzed 1996-2010 data from the U.S. Renal Data System (USRDS) and the Behavioral Risk Factor Surveillance System (BRFSS). After increasing in the late 1990s, ESRD-D incidence decreased during the 2000s among adult men and among persons aged 18-44 years with diagnosed diabetes in Puerto Rico. Throughout the period, ESRD-D incidence among adult women and among persons aged 45-64 and ≥75 years with diagnosed diabetes did not show a consistent trend, and ESRD-D incidence among persons aged 65-74 years with diagnosed diabetes increased. Increased awareness of the risk factors for kidney disease and implementation of effective interventions to prevent or delay kidney disease among persons with diagnosed diabetes might decrease ESRD incidence in Puerto Rico, particularly among women and older persons.

During October 2013, an ocean exploration project took place off the coast of Puerto Rico and the Virgin Islands. This project, a collaborative effort between the Ocean Exploration Trust, the US Geological Survey, the University of Puerto Rico at Mayaguez, the University of Rhode Island, and NOAA, was aimed at exploring regions of the US exclusive economic zone (EEZ) south of the Puerto Rico Trench axis, and north of Mona Island, Puerto Rico, and the US and British Virgin Islands, and portions of the Anegada Passage. The research vessel E/V Nautilus and the Hercules/Argus ROV system were used to expand the multibeam sonar bathymetric data coverage of the region, collect high definition video footage of seafloor features, and to collect biological and geological samples along selected transects. Particular areas of interest for targeted ROV dives included: the region where a large M7.2 1918 earthquake produced a tsunami that struck northwestern corner of Puerto Rico; a transect up the vertical wall of the Mona Rift (4000 to 1500 m depth); transects along the Septentrional fault system; dives in areas of suspected fluid flow through faults, fissures, and offshore Karst systems associated with the tilted carbonate platform north of Puerto Rico; dives in the Anegada Passage at the entry points for surface Atlantic waters that circulate into the Caribbean; and in regions to investigate and date sedimentary features offset by fault motion and potential tsunamigenic landslides. Biological sampling of many deep-sea benthic organisms (including deep water corals) have never been attempted before in this area. These samples are being used to understand more about the diversity, population dynamics, genetics, and habitat connectivity of these communities, and to provide an age constraint for disturbed sedimentary features. Until this cruise, the location and distribution of deep coral habitats in the US Caribbean was largely unknown. The available information on benthic

Activation of the cellular unfolded protein response by recombinant adeno-associated virus vectors.

Full Text Available The unfolded protein response (UPR is a stress-induced cyto-protective mechanism elicited towards an influx of large amount of proteins in the endoplasmic reticulum (ER. In the present study, we evaluated if AAV manipulates the UPR pathways during its infection. We first examined the role of the three major UPR axes, namely, endoribonuclease inositol-requiring enzyme-1 (IRE1α, activating transcription factor 6 (ATF6 and PKR-like ER kinase (PERK in AAV infected cells. Total RNA from mock or AAV infected HeLa cells were used to determine the levels of 8 different ER-stress responsive transcripts from these pathways. We observed a significant up-regulation of IRE1α (up to 11 fold and PERK (up to 8 fold genes 12-48 hours after infection with self-complementary (scAAV2 but less prominent with single-stranded (ssAAV2 vectors. Further studies demonstrated that scAAV1 and scAAV6 also induce cellular UPR in vitro, with AAV1 vectors activating the PERK pathway (3 fold while AAV6 vectors induced a significant increase on all the three major UPR pathways [6-16 fold]. These data suggest that the type and strength of UPR activation is dependent on the viral capsid. We then examined if transient inhibition of UPR pathways by RNA interference has an effect on AAV transduction. siRNA mediated silencing of PERK and IRE1α had a modest effect on AAV2 and AAV6 mediated gene expression (∼1.5-2 fold in vitro. Furthermore, hepatic gene transfer of scAAV2 vectors in vivo, strongly elevated IRE1α and PERK pathways (2 and 3.5 fold, respectively. However, when animals were pre-treated with a pharmacological UPR inhibitor (metformin during scAAV2 gene transfer, the UPR signalling and its subsequent inflammatory response was attenuated concomitant to a modest 2.8 fold increase in transgene expression. Collectively, these data suggest that AAV vectors activate the cellular UPR pathways and their selective inhibition may be beneficial during AAV mediated gene transfer.

Methods for monitoring endoplasmic reticulum stress and the unfolded protein response.

LENUS (Irish Health Repository)

Samali, Afshin

2010-01-01

The endoplasmic reticulum (ER) is the site of folding of membrane and secreted proteins in the cell. Physiological or pathological processes that disturb protein folding in the endoplasmic reticulum cause ER stress and activate a set of signaling pathways termed the Unfolded Protein Response (UPR). The UPR can promote cellular repair and sustained survival by reducing the load of unfolded proteins through upregulation of chaperones and global attenuation of protein synthesis. Research into ER stress and the UPR continues to grow at a rapid rate as many new investigators are entering the field. There are also many researchers not working directly on ER stress, but who wish to determine whether this response is activated in the system they are studying: thus, it is important to list a standard set of criteria for monitoring UPR in different model systems. Here, we discuss approaches that can be used by researchers to plan and interpret experiments aimed at evaluating whether the UPR and related processes are activated. We would like to emphasize that no individual assay is guaranteed to be the most appropriate one in every situation and strongly recommend the use of multiple assays to verify UPR activation.

Resquicios de materialismo histórico en la historia económica española

Trincado Aznar Estrella

2012-09-01

Full Text Available Este artículo hace un repaso de la influencia del materialismo histórico en la historia económica mediante el estudio del caso español. Un análisis de oferta y demanda de ideas muestra que durante las décadas de 1960 y 1970 hubo un florecimiento del marxismo y el materialismo histórico. Durante el decenio de 1980 este enfoque seguía siendo importante; sin embargo, durante los años 1990, las escuelas de historia trataron de parecer neutrales y quisieron relegar el marxismo. En cualquier caso, a pesar del rechazo teórico a esta tendencia historiográfica --expresamente residual--, ésta sigue influyendo en la historia económica y se encuentra implícitamente en el corazón de muchas investigaciones que no se consideran marxistas.

Profiling of Alzheimer's disease patients in Puerto Rico: A comparison of two distinct socioeconomic areas.

The Latino/Hispanic community in the United States is at higher risk of developing Alzheimer's disease than other ethnic groups. Specifically, Caribbean Hispanics showed a more severe Alzheimer's disease symptomatology than any other ethnic group. In a previous study, we demonstrated that the mortality rate associated with Alzheimer's disease in Puerto Rico is higher than that reported in the United States. Moreover, the mortality rate associated with Alzheimer's disease was higher among Puerto Rican living in Puerto Rico than those in the mainland United States. There is also a differential geographical distribution of mortality rate associated with Alzheimer's disease in Puerto Rico, which may be associated with differential socioeconomic status and/or access to healthcare. However, there is no information regarding the clinical profile of Alzheimer's disease patients in Puerto Rico. Here, we present the results of a retrospective study directed to profile Alzheimer's disease patients clustered into two groups based on areas previously determined with low (Metro Region) and high (Northwest-Central Region) mortality rate associated with Alzheimer's disease in Puerto Rico. Significant difference in the age-at-diagnosis and years of education was found among patients within the two studied regions. Despite these differences, both regions showed comparable levels of initial and last Mini Mental State Examination scores and rate of cognitive decline. Significant difference was also observed in the occurance of co-morbidities associated with Alzheimer's disease. The differential profile of Alzheimer's disease patients correlated with differences in socioeconomic status between these two regions, suggesting that covariant associated with social status may contribute to increased risk of developing Alzheimer's disease. Further studies should be conducted to determine the role of socioeconomic factors and healthy living practices as risk factors for Alzheimer's disease.

The eastern North America-Caribbean (NA-CAR) plate boundary near the islands of Hispaniola (which is comprised of the Dominican Republic and Haiti) and Puerto Rico is a complex transition zone in which strain is accommodated by two transform fault systems and oblique subduction. In 2013, scientists from Baylor University, the Autonomous University of Santo Domingo, and the Puerto Rico Seismic Network deployed 16 broadband stations on the Dominican Republic to expand the local permanent network. The goal of the Greater Antilles Seismic Program (GrASP) is to combine its data with that from permanent networks in Puerto Rico, Haiti, Cuba, the Cayman Islands, and Jamaica to develop a better understanding of the crust and upper mantle structure in the Northeastern Caribbean (Greater Antilles). One important goal of GrASP is to develop robust velocity models that can be used to improve earthquake location and seismic hazard efforts. In this study, we focus on obtaining Rayleigh wave group velocity maps from ambient noise tomography. By cross-correlating ambient seismic noise recorded at 53 stations between 2010 to present, we obtain Green's functions between 1165 pairs of stations. From these, we obtain dispersion curves by the application of FTAN methods with phase-matched filtering. Selection criteria depend on the signal-to-noise ratio and seasonal variability, with further filtering done by rejecting velocities incompatible with maps produced from overdamped tomographic inversions. Preliminary dispersion maps show strong correlations with large-scale geological and tectonic features for periods between 5 - 20 s, such as the Cordillera Central in both the Dominican Republic and Puerto Rico, the Mona Passage, and the NA-CAR subduction zone. Ongoing efforts focus on including shorter periods in Puerto Rico as its denser station distribution could allow us to retrieve higher resolution group velocity maps.

Full Text Available The main goal of this work was the development of fully biobased unsaturated polyesters (UPs that upon crosslinking with unsaturated monomers (UM could lead to greener unsaturated polyester resins (UPRs with similar thermomechanical properties to commercial fossil based UPR. After the successful synthesis of the biobased UPs, those were crosslinked with styrene (Sty, the most commonly used monomer, and the influence of the chemical structure of the UPs on the thermomechanical characteristics of UPRs were evaluated. The properties were compared with those of a commercial resin (Resipur 9837©. The BioUPRs presented high gel contents and contact angles that are similar to the commercial resin. The thermomechanical properties were evaluated by dynamic mechanical thermal analysis (DMTA and it was found that the UPR synthesized using propylene glycol (PG, succinic acid (SuAc and itaconic acid (ItAc presented very close thermomechanical properties compared to the commercial resin.

mtDNA, Metastasis, and the Mitochondrial Unfolded Protein Response (UPRmt).

2017-01-01

While several studies have confirmed a link between mitochondrial DNA (mtDNA) mutations and cancer cell metastasis, much debate remains regarding the nature of the alternations in mtDNA leading to this effect. Meanwhile, the mitochondrial unfolded protein response (UPR mt ) has gained much attention in recent years, with most studies of this pathway focusing on its role in aging. However, the UPR mt has also been studied in the context of cancer. More recent work suggests that rather than a single mutation or alternation, specific combinatorial mtDNA landscapes able to activate the UPR mt may be those that are selected by metastatic cells, while mtDNA landscapes unable to activate the UPR mt do not. This review aims at offering an overview of the confusing literature on mtDNA mutations and metastasis and the more recent work on the UPR mt in this setting.

Herbaceous land plants as a renewable energy source for Puerto Rico

Energy Technology Data Exchange (ETDEWEB)

Alexander, A.G.

1980-01-01

Herbaceous tropical plants are a renewable energy source of major importance to many tropical nations. They convert the radiant energy of sunlight to chemical energy, which is stored in plant tissues (cellulose, hemicellulose, lignin) and fermentable solids (sugars, starches). Because all tropical plants do this - even those commonly regarded as weeds - they constitute an inexpensive, renewable, and domestic alternative to foreign fossil energy. The vast majority of herbaceous tropical plants have never been cultivated for food, fiber, or energy. A major screening program would be needed to identify superior species and the most effective roles they can play in a domestic energy industry. Other herbaceous plants, such as sugarcane and tropical forage grasses, have been cultivated for centuries as agricultural commodities. As energy crops, important revisions in management will be needed to maximize their energy yield. Two broad groups of herbaceous plants are seen to have an immediate potential for reducing Puerto Rico's reliance on imported fossil fuels: the tropical grasses (of which sugarcane is the dominant member) and the tropical legumes. Managed for its maximum growth potential, sugarcane is an excellent source of boiler fuel, fermentation substrates, cellulosic feedstocks, and the sweetener sucrose. Other tropical grasses store relatively little extractable sugar while equaling or moderately surpassing sugarcane in yield of cellulosic dry matter. The latter might soon become an economical source of fermentation substrates. Certain legume species are also very effective producers of biomass. Herbaceous tropical legumes are perceived as a potential source of biological nitrogen for energy crops unable to utilize nitrogen from the atmosphere.

Feasibility determination of hydroelectric power generation at Patillas Reservoir, Puerto Rico. Final report

Energy Technology Data Exchange (ETDEWEB)

Huetter, J.J. Jr.

1979-02-01

The overall feasibility of retrofit for hydroelectric power generation at the Patillas Reservoir, an existing impoundment located near the town of Patillas, Puerto Rico, was studied. The scope of work and project intent is limited to establishing valid acceptance or non-acceptance criteria for this specific site as an example of power generation potential at existing dams of relatively low head (less than or equal to 20 m) in the United States. Information is included on hydrologic conditions at the site, retrofit plant design, economic analysis, environmental, legal, social and institutional aspects, and availability of plant equipment. It is concluded that generation of hydropower at Patillas is entirely practical and uncomplicated from an engineering viewpoint, has no adverse environmental effects and is economically justifiable for the island of Puerto Rico. The final agency or contractor roles for development are reasonably well-established. There are no prohibitory laws or regulations concerning this development. In fact, according to Puerto Rico legislation, such hydropower developments appear to be mandated. The installed capacity of the site ranges from 665 kW to approximately 1500 kW depending on extent of development of the available options. (LCL)

The outcomes were: the proportion of generics in total medicines used; theoretical and practical knowledge about generics; and strategies used to buy medicines on medical prescriptions. The recall period for drug utilization was 15 days. The proportion of generics in total medicines was 3.9%. While 86.0% knew that generics cost less and 70.0% that the quality is similar to brand name medicines, only 57.0% knew any packaging characteristics that distinguish generics from other medicines. The highest proportion of generic drug utilization was in the antimicrobial pharmacological group. A brand name medicine (with a brand similar to the generic name was mistakenly classified as a generic through photos by 48.0% of the interviewees. Among subjects who bought medicines in the 15-day period, 18.9% reported buying a generic, but this result should be interpreted with caution, because the population frequently fails to differentiate between generics and other medicines.Este estudo avaliou o conhecimento e utilização de medicamentos genéricos em uma amostra populacional de adultos de uma cidade no sul do Brasil.

Geographic, racial, and ethnic variations in quality of care and outcomes have been well documented among the Medicare population. Few data exist on beneficiaries living in Puerto Rico, three-quarters of whom enroll in Medicare Advantage (MA). To determine the quality of care provided to white and Hispanic MA enrollees in the United States and Puerto Rico. A cross-sectional study of MA enrollees in 2011 was conducted, including white enrollees in the United States (n = 6 289 374), Hispanic enrollees in the United States (n = 795 039), and Hispanic enrollees in Puerto Rico (n = 267 016). The study was conducted from January 1, 2011, to December 31, 2011; data analysis took place from January 19, 2015, to January 2, 2016. Seventeen performance measures related to diabetes mellitus (including hemoglobin A1c control, retinal eye examination, low-density lipoprotein cholesterol control, nephropathy screening, and blood pressure control), cardiovascular disease (including low-density lipoprotein cholesterol control, blood pressure control, and use of a β-blocker after myocardial infarction), cancer screening (colorectal and breast), and appropriate medications (including systemic corticosteroids and bronchodilators for chronic obstructive pulmonary disease [COPD] and disease-modifying antirheumatic drugs). Of the 7.35 million MA enrollees in the United States and Puerto Rico in our study, 1.06 million (14.4%) were Hispanic. Approximately 25.1% of all Hispanic MA enrollees resided in Puerto Rico, which was more than those residing in any state. For 15 of the 17 measures assessed, Hispanic MA enrollees in Puerto Rico received worse care compared with Hispanics in the United States, with absolute differences in performance rates ranging from 2.2 percentage points for blood pressure control in diabetes mellitus (P = .03) to 31.3 percentage points for use of disease-modifying antirheumatic drug therapy (P Puerto Rico and Hispanic MA enrollees in the

Preventive-care practices among adults with diabetes--Puerto Rico, 2000-2002.

Science.gov (United States)

2004-11-12

Preventive-care practices among persons with diabetes can prevent or delay complications such as eye disease, kidney disease, or nerve damage that is a precursor to disabling foot disease. However, the level of diabetes-related preventive care is inadequate in the United States, and little has been reported about preventive care in Puerto Rico, where an estimated 10% of adults have diagnosed diabetes. CDC analyzed data from 2000, 2001, and 2002 Behavioral Risk Factor Surveillance System (BRFSS) surveys to assess the percentage of adults with diabetes in Puerto Rico who engaged in five selected preventive-care practices. This report summarizes the results of that analysis, which indicated that, with the exception of hemoglobin A1c testing, the percentages of adults engaging in preventive-care practices were lower than the target percentages set by U.S. national health objectives for 2010.

Puerto Rico is the United States' largest territory, home to nearly 4 million American citizens, yet it has remained largely on the outskirts of US health policy, including the Affordable Care Act (ACA). We analyzed national survey data from 2011 to 2012 and found that despite its far poorer population, Puerto Rico outperforms the mainland United States on several measures of health care coverage and access to care. While the ACA significantly increases federal resources in Puerto Rico, ongoing federal restrictions on Medicaid funding and premium tax credits in Puerto Rico pose substantial health policy challenges in the territory. Puerto Rico is the United States' largest territory, home to nearly 4 million American citizens. Yet it has remained largely on the outskirts of US health policy, including the Affordable Care Act (ACA). This article presents an overview of Puerto Rico's health care system and a comparative analysis of coverage and access to care in Puerto Rico and the mainland United States. We analyzed 2011-2012 data from the Behavioral Risk Factor Surveillance System, and 2012 data from the American Community Survey and its counterpart, the Puerto Rico Community Survey. Among adults 18 and older, we examined health insurance coverage; access measures, such as having a usual source of care and cost-related delays in care; self-reported health; and the receipt of recommended preventive services, such as cancer screening and glucose testing. We used multivariate regression models to compare Puerto Rico and the mainland United States, adjusted for age, income, race/ethnicity, and other demographic variables. Uninsured rates were significantly lower in Puerto Rico (unadjusted 7.4% versus 15.0%, adjusted difference: -12.0%, p Puerto Rico. Puerto Rican residents were more likely than those in the mainland United States to have a usual source of care and to have had a checkup within the past year, and fewer experienced cost-related delays in care.

Full Text Available Ethanol is a valuable industrial product and a common metabolite used by many cell types. However, this molecule produces high levels of cytotoxicity affecting cellular performance at several levels. In the presence of ethanol, cells must adjust some of their components, such as the membrane lipids to maintain homeostasis. In the case of microorganism as Saccharomyces cerevisiae, ethanol is one of the principal products of their metabolism and is the main stress factor during fermentation. Although many efforts have been made, mechanisms of ethanol tolerance are not fully understood and very little evidence is available to date for specific signaling by ethanol in the cell. This work studied two Saccharomyces cerevisiae strains, CECT10094 and Temohaya-MI26, isolated from flor wine and agave fermentation (a traditional fermentation from Mexico respectively, which differ in ethanol tolerance, in order to understand the molecular mechanisms underlying the ethanol stress response and the reasons for different ethanol tolerance. The transcriptome was analyzed after ethanol stress and, among others, an increased activation of genes related with the unfolded protein response (UPR and its transcription factor, Hac1p, was observed in the tolerant strain CECT10094. We observed that this strain also resist more UPR agents than Temohaya-MI26 and the UPR-ethanol stress correlation was corroborated observing growth of 15 more strains and discarding UPR correlation with other stresses as thermal or oxidative stress. Furthermore, higher activation of UPR pathway in the tolerant strain CECT10094 was observed using a UPR mCherry reporter. Finally, we observed UPR activation in response to ethanol stress in other S. cerevisiae ethanol tolerant strains as the wine strains T73 and EC1118. This work demonstrates that the UPR pathway is activated under ethanol stress occurring in a standard fermentation and links this response to an enhanced ethanol tolerance. Thus

Seismic and tsunami hazard in Puerto Rico and the Virgin Islands

Science.gov (United States)

Dillon, William P.; Frankel, Arthur D.; Mueller, Charles S.; Rodriguez, Rafael W.; ten Brink, Uri S.

1999-01-01

Executive SummaryPuerto Rico and the Virgin Islands are located at an active plate boundary between the North American plate and the northeast corner of the Caribbean plate. The region was subject in historical times to large magnitude earthquakes and devastating tsunamis. A major downward tilt of the sea floor north of Puerto Rico and the Virgin Islands, large submarine rockslides, and an unusually large negative gravity anomaly are also indicative of a tectonically active region. Scientists have so far failed to explain the deformation of this region in a coherent and predictable picture, such as in California, and this has hampered their ability to assess seismic and tsunami hazards in the region. The NE corner of the Caribbean is unique among the seismically-active regions of the United States in that it is mostly covered by water. This fact presents an additional challenge for seismic and tsunami hazard assessment and mitigation.The workshop, convened in San Juan on March 23-24, 1999, was "historic" in that it brought together for the first time a broad spectrum of scientists, engineers, and public and private sector officials who deal with such diverse questions as tectonic models, probabilistic assessment of seismic hazard, prediction of tsunami runup, strong ground motion, building codes, stability of man-made structures, and the public’s preparedness for natural disasters. It was an opportunity for all the participants to find out how their own activity fit into the broad picture of science and how it aids society in hazard assessment and mitigation. In addition, the workshop was offered as a continuing education course at the Colegio de Ingenieros y Agrimensores de Puerto Rico, which assured a rapid dissemination of the results to the local community. A news conference which took place during the workshop alerted the public to the efforts of the USGS, other Federal agencies, the Commonwealth of Puerto Rico, universities and the private sector.During the

2012-06-01

This brief celebration of the work of Francisco Guerra (1916-2011) highlights his role as mentor for an international community, his study of local events in the context of global developments, and his contributions to the understanding of the medical history of Puerto Rico. A selective review of Francisco Guerra's methods and publications shows that his principal works are characterized by their vast scope and exhaustive coverage of ancient and modern published sources, coupled with clarity and conciseness of exposition. At least eight of his books (presented here) provide important information on events and personalities in Puerto Rico up to about 1940. Guerra, through his clinical experience, profound scholarship, and personal contacts, recovered the local medical developments of peripheral areas and incorporated them to a global context.

2018-05-08

Asthma and psychosocial stressors are common among Puerto Rican adults living in the United States. We estimated the prevalence of current asthma, and examined potential psychosocial risk factors and current asthma, among adults in Puerto Rico. Cross-sectional study of 3,049 Puerto Ricans aged 18-64 years living in Puerto Rico between May 2014 and June 2016. A structured interview was conducted to obtain information on demographics, lifestyles, mental disorders, and respiratory health. Current asthma was defined as self-reported physician-diagnosed asthma and still having asthma. Two-sample t tests (for continuous variables) or chi-square tests (for categorical variables) were used in bivariate analyses. Multivariable logistic regression was used to examine psychosocial risk factors and current asthma. The estimated prevalence of current asthma was 10.2%. In a multivariable analysis, exposure to violence (odds ratio [OR] for each 1-point increment in a validated scale = 1.14, 95% confidence interval [CI] = 1.07 to 1.21) and a lifetime history of at least one suicide attempt (OR = 3.01, 95% CI = 1.80 to 5.01) were significantly associated with current asthma, independently of major depressive disorder. Moreover, a lifetime history of at least one suicide attempt was associated with co-existing asthma and chronic obstructive pulmonary disease (i.e. asthma-COPD overlap syndrome or ACOS (OR = 9.05, 95% CI = 3.32-24.67). Our findings suggest that asthma is a major health problem among adults in Puerto Rico, with psychosocial risk factors playing a significant role on asthma and ACOS. Addressing chronic stressors and mental illness should be part of comprehensive strategies to reduce asthma burden in this population.

In this perspective, well dispersion of multi-walled carbon nanotubes (MWCNTs) in unsaturated polyester resin (UPR) was prepared using pre-dispersed MWCNTs in tetrahydrofuran solvent with ultrasonication method. Then the well-dispersed MWCNTs reinforced UPR nanocomposites were fabricated through solvent evaporation. Fourier-transform infrared spectroscopy indicates a good interaction between matrix and MWCNTs. This along with homogeneous dispersion of nanotubes in matrix has been confirmed by the field emission scanning electron microscopy. At low shear rate, the value of viscosity of UPR is 8,593 mPa s and that of pre-dispersed MWCNT–UPR suspension is 43,491 mPa s, showing implicitly a good dispersion of nanotubes. A notable improvement in the crystallinity of UPR from 14 to 21 % after MWCNTs inclusion was observed by X-ray diffractometry. The mechanical properties, such as tensile strength, tensile modulus, impact strength, and elongation-at-break, of nanocomposite were found to be increased to 22, 20, 28, and 87 %, respectively. The estimated melting enthalpy per gram for composites as analyzed by differential scanning calorimetry is higher than that of UPR. The onset temperature of thermal decomposition in the nanocomposites as monitored by thermogravimetric analysis is found higher than that of UPR. Correlations among MWCNTs dispersion, nucleation, fracture morphology, and various properties were measured and reported.

The UPR-600-16, Fire and Contamination Spread waste site is an unplanned release that occurred on December 4, 1951, when plutonium contamination was spread by a fire that ignited inside the 120 Experimental Building. The 120 Experimental Building was a laboratory building that was constructed in 1949 and used for plutonium criticality studies as part of the P-11 Project. In November 1951, a criticality occurred in the 120 Experimental Building that resulted in extensive plutonium contamination inside the building. The confirmatory evaluation supports a reclassification of this site to Interim Closed Out. The current site conditions achieve the remedial action objectives and the corresponding remedial action goals established in the Remaining Sites ROD. The results of the extensive radiological survey of the surface soil and the confirmatory and verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River

Precise patterning of dendritic fields is essential for the formation and function of neuronal circuits. During development, dendrites acquire their morphology by exuberant branching. How neurons cope with the increased load of protein production required for this rapid growth is poorly understood. Here we show that the physiological unfolded protein response (UPR) is induced in the highly branched Caenorhabditis elegans sensory neuron PVD during dendrite morphogenesis. Perturbation of the IRE1 arm of the UPR pathway causes loss of dendritic branches, a phenotype that can be rescued by overexpression of the ER chaperone HSP-4 (a homolog of mammalian BiP/ grp78). Surprisingly, a single transmembrane leucine-rich repeat protein, DMA-1, plays a major role in the induction of the UPR and the dendritic phenotype in the UPR mutants. These findings reveal a significant role for the physiological UPR in the maintenance of ER homeostasis during morphogenesis of large dendritic arbors.

Rodríguez, José R; Rodríguez, Rosa Janet; Disdier, Orville M

2007-03-01

The prevalence of diabetes mellitus in Puerto Ricans has been identified and reported as being disproportionately higher as compared to other metabolic pathologies. Recently, diabetes has been identified as the third cause of mortality in Puerto Rico (Puerto Rico Health Department, Vital Statistics Annual Report, 1999-2001). The Research Center, Education and Medical Services for Diabetes in Puerto Rico (also known as the "Centro de Diabetes para Puerto Rico" [CDPR]) is a public corporation in the island created by the government to reduce diabetes prevalence, mortality and morbidity. The CDPR offers Diabetes Self Management Educational Training Program Schools for patients (DSMETPS) island wide. The research design was an ex-post facto. As part of the process, patients are administered an extensive sociodemographic and health information questionnaire, which also includes the CES-D (a symptomatology depressive scale). This study pretends to describe the diabetic patient profiles (n=27) using information from the DSMETPS of the CDPR and explore the association with the CES-D. Variables such as patients' needs, knowledge and understanding of the condition (i.e., pathology management, type and medications utilized and exercise and nutritional patterns), patient attitudes to diabetes and their relations with the CES-D were explored. Results show a negative association, controlling for age and gender, between patients diabetic education/knowledge and CES-D score. Diabetes educators in Puerto Rico need to identify depressive symptomatology in order to prevent mental health complications in their patients since this may affect their future treatment and prognosis. An interdisciplinary team is recommended to improve the effectivity of the intervention.

2015-12-01

To determine the levels of satisfaction, license status, and desire to relocate of pediatric dentists in Puerto Rico. Pediatric dentists in Puerto Rico were surveyed via telephone interviews. Data were collected through a 34-item questionnaire that explored satisfaction as related to income, continuing education, professional goals, and participation in the Mi Salud program. Frequencies, chi-square analysis, and Fisher's exact 2-tailed t-test were utilized to determine the relationships between satisfaction and the demographics of the pediatric dentists. Sixty pediatric dentists participated in our survey-77% of the total number of pediatric dentists practicing in Puerto Rico. Overall, 65% of the participating pediatric dentists expressed dissatisfaction. Male pediatric dentists were more dissatisfied than their female colleagues were. Most pediatric dentists participating in Mi Salud expressed dissatisfaction. When asked about whether or not they had considered migrating to the mainland, those who were dissatisfied were more likely to have considered that idea than were those who were satisfied. Overall, 57% of the pediatric dentists comprising our sample had considered relocating to the continental United States. In general, the pediatric dentists who participated in our study expressed dissatisfaction in most areas except when asked about their ability to reach professional goals. Determining the levels of satisfaction of health care providers is important in the maintaining of an adequate workforce. As current levels of dissatisfaction are high, it is important to determine what variables are related to satisfaction so that corrective measures can be taken to ensure that retention rates improve, thereby maintaining an adequate pediatric dental workforce.

Necropsies were conducted on 4 Antillean manatees Trichechus manatus manatus that were stranded in single events on the coastal beaches of Puerto Rico from August 2010 to August 2011. Three manatees were emaciated and the gastrointestinal tracts were devoid of digesta. Microscopically, all manatees had severe widespread inflammatory lesions of the gastrointestinal tract and heart with intralesional tachyzoites consistent with Toxoplasma gondii identified by histological, ultrastructural and immunohistochemical techniques. The gastrointestinal lesions included severe, multifocal to diffuse, chronic-active enteritis, colitis and/or gastritis often with associated ulceration, necrosis and hemorrhage. Enteric leiomyositis was severe and locally extensive in all cases and associated with the most frequently observed intralesional protozoans. Moderate to severe, multifocal, chronic to chronic-active, necrotizing myocarditis was also present in all cases. Additionally, less consistent inflammatory lesions occurred in the liver, lung and a mesenteric lymph node and were associated with fewer tachyzoites. Sera (n = 30) collected from free-ranging and captive Puerto Rican manatees and a rehabilitated/released Puerto Rican manatee from 2003 to 2012 were tested for antibodies for T. gondii. A positive T. gondii antibody titer was found in 2004 in 1 (3%) of the free-ranging cases tested. Disease caused by T. gondii is rare in manatees. This is the first report of toxoplasmosis in Antillean manatees from Puerto Rico. Additionally, these are the first reported cases of disseminated toxoplasmosis in any sirenian. The documentation of 4 cases of toxoplasmosis within one year and the extremely low seroprevalence to T. gondiisuggest that toxoplasmosis may be an emerging disease in Antillean manatees from Puerto Rico.

Effects of ubiquilin 1 on the unfolded protein response.

Previous studies have implicated the unfolded protein response (UPR) in the pathogenesis of Alzheimer's disease (AD). We previously reported that DNA variants in the ubiquilin 1 (UBQLN1) gene increase the risk for AD. Since UBQLN1 has been shown to play a role in the UPR, we assessed the effects of overexpression and downregulation of UBQLN1 splice variants during tunicamycin-induced ER stress. In addition to previously described transcript variants, TV1 and TV2, we identified two novel transcript variants of UBQLN1 in brain: TV3 (lacking exons 2-4) and TV4 (lacking exon 4). Overexpression of TV1-3, but not TV4 significantly decreased the mRNA induction of UPR-inducible genes, C/EBP homologous protein (CHOP), BiP/GRP78, and protein disulfide isomerase (PDI) during the UPR. Stable overexpression of TV1-3, but not TV4, also significantly decreased the induction of CHOP protein and increased cell viability during the UPR. In contrast, downregulation of UBQLN1 did not affect CHOP mRNA induction, but instead increased PDI mRNA levels. These findings suggest that overexpression UBQLN1 transcript variants TV1-3, but not TV4, exert a protective effect during the UPR by attenuating CHOP induction and potentially increasing cell viability.

Water quality and landscape processes of four watersheds in eastern Puerto Rico

Humid tropical regions occupy about a quarter of Earth's land surface, yet they contribute a substantially higher fraction of the water, solutes, and sediment discharged to the world's oceans. Nearly half of Earth's population lives in the tropics, and development stresses can potentially harm soil resources, water quality, and water supply and in addition increase landslide and flood hazards. Owing to Puerto Rico's steep topography, low water storage capacity, and dependence on trade-wind precipitation, the island's people, ecosystems, and water supply are vulnerable to extreme weather such as hurricanes, floods, and droughts. Eastern Puerto Rico offers a natural laboratory for separating geologic and land-cover influences from regional- and global-scale influences because of its various bedrock types and the changing land cover surrounding intact, mature forest of the Luquillo Experimental Forest. Accordingly, a multiyear assessment of hydrological and biogeochemical processes was designed to develop an understanding of the effects of these differences on local climate, streamflow, water quality, and ecosystems, and to form the basis for a long-term and event-based program of climate and hydrologic monitoring. Because infrequent, large storms play a major role in this landscape, we focused on high-runoff events, sampling 263 storms, including all major hurricanes from 1991 through 2005. The largest storms have profound geomorphic consequences, such as landslides, debris flows, deep gullying on deforested lands, excavation and suspension of sediment in stream channels, and delivery of a substantial fraction of annual stream sediment load. Large storms sometimes entrain ocean foam and spray causing high concentrations of seasalt-derived constituents in stream waters during the storm. Past deforestation and agricultural activities in the Cayaguás and Canóvanas watersheds accelerated erosion and soil loss, and this material continues to be remobilized during large

Profiling of Alzheimer’s disease patients in Puerto Rico: A comparison of two distinct socioeconomic areas

Directory of Open Access Journals (Sweden)

Clara L Camacho-Mercado

2016-01-01

Full Text Available Objective: The Latino/Hispanic community in the United States is at higher risk of developing Alzheimer’s disease than other ethnic groups. Specifically, Caribbean Hispanics showed a more severe Alzheimer’s disease symptomatology than any other ethnic group. In a previous study, we demonstrated that the mortality rate associated with Alzheimer’s disease in Puerto Rico is higher than that reported in the United States. Moreover, the mortality rate associated with Alzheimer’s disease was higher among Puerto Rican living in Puerto Rico than those in the mainland United States. There is also a differential geographical distribution of mortality rate associated with Alzheimer’s disease in Puerto Rico, which may be associated with differential socioeconomic status and/or access to healthcare. However, there is no information regarding the clinical profile of Alzheimer’s disease patients in Puerto Rico. Methods: Here, we present the results of a retrospective study directed to profile Alzheimer’s disease patients clustered into two groups based on areas previously determined with low (Metro Region and high (Northwest-Central Region mortality rate associated with Alzheimer’s disease in Puerto Rico. Results: Significant difference in the age-at-diagnosis and years of education was found among patients within the two studied regions. Despite these differences, both regions showed comparable levels of initial and last Mini Mental State Examination scores and rate of cognitive decline. Significant difference was also observed in the occurance of co-morbidities associated with Alzheimer’s disease. Conclusions: The differential profile of Alzheimer’s disease patients correlated with differences in socioeconomic status between these two regions, suggesting that covariant associated with social status may contribute to increased risk of developing Alzheimer’s disease. Further studies should be conducted to determine the role of

Objective To determine the prevalence of hypothyroidism in an adult female population in Puerto Rico and to determine the relationship between hypothyroidism, bone mineral density and vertebral and non-vertebral fractures in this population. Methods Data from the 400 subjects database of the Latin American Vertebral Osteoporosis Study (LAVOS), Puerto Rico site was reviewed. Patient’s medical history, anthropometric data, current medications, laboratories, and DXA results was extracted. Subjects with thyroid dysfunction were identified based on their previous medical history and levels of TSH. Bone Mineral Density was classified using the World Health Organization criteria. Crude prevalence of thyroid dysfunction were estimated with a confidence of 95% and weighted by the population distribution by age, according to the distribution by age group in the 2000 census. Bone mineral densities and prevalence of vertebral and non-vertebral fractures were compared among the groups. Results The weighted prevalence of hyperthyroidism in this population was 0.0043% (95% CI: −0.0021%, 0.0107%). The weighted prevalence of hypothyroidism was 24.2% (95% CI: 19.9%, 28.4%). Increased prevalence of hypothyroidism was found in participants 70 years or older. The mean BMD at spine, hip and femoral neck was similar among the groups. No difference in the proportion of participants with vertebral and non-vertebral fractures was found among the groups. Conclusion Our study found a high prevalence of hypothyroidism among adult postmenopausal females in Puerto Rico. No association between hypothyroidism and decreased bone mineral densities, vertebral or non-vertebral fractures was found in this population. PMID:23781620

Stallard, Robert F.; Murphy, Sheila F.; Stallard, Robert F.

Twenty years of precipitation-chemistry data from the National Atmospheric Deposition Program site at El Verde, Puerto Rico, demonstrate that three major sources control the composition of solutes in rain in eastern Puerto Rico. In order of importance, these sources are marine salts, temperate contamination from the Northern Hemisphere, and Sahara Desert dust. Marine salts are a source of roughly 82 percent of the ionic charge in precipitation; marine salt inputs are greatest in January. Evaluation of 15 years of U.S. Geological Survey data for four watersheds in eastern Puerto Rico suggests that large storms, including hurricanes, are associated with exceptionally high chloride concentrations in stream waters. Some of these storms were missed in sampling by the National Atmospheric Deposition Program, and therefore its data on the marine contribution likely underestimate chloride. The marine contribution is a weak source of acidity. Temperate contamination contributes about 10 percent of the ionic charge in precipitation; contaminants are primarily nitrate, ammonia, and sulfate derived from various manmade and natural sources. Peak deposition of temperate contaminants is during January, April, and May, months in which strong weather fronts arrive from the north. Temperate contamination, a strong source of acidity, is the only component that is increasing through time. Sahara Desert dust provides 5 percent of the ionic charge in precipitation; it is strongly seasonal, peaking in June and July during times of maximum dust transport from the Sahara and sub-Saharan regions. This dust contributes, on average, enough alkalinity to neutralize the acidity in June and July rains.

Multivariate analyses such as multiple linear regression (MLR) and factor analysis (FA) are used to classify, extract and interpret the household water-use costs. The FA results suggest two principal varifactors in explaining the variability of household water-use costs (64% in 2000 and 50% in 2010), which are grouped into a soft coefficient (social, economic and demographic characteristics of household residents, i.e., age, size, income, education) and a hard coefficient (dwelling conditions, i.e., number of rooms, units in the building, building age). The demographic profile of a high water-use household in Puerto Rico tends to be that of renters, people who live in larger or older buildings, people living in metro areas, or those with higher education level and higher income. The findings and discussions from this study will help decision makers to plan holistic and integrated water management to achieve water sustainability. Copyright © 2015 Elsevier B.V.

EL ENFOQUE HISTÓRICO CULTURAL EN EL ESTUDIO DEL DESARROLLO HUMANO: PARA UNA PRAXIS HUMANISTA

Directory of Open Access Journals (Sweden)

Full Text Available Muchos investigadores dedicados al campo de la educación han realizado estudios en los últimos años basándose en los conceptos del enfoque histórico cultural. Desafortunadamente en muchas ocasiones conocen pobremente las principales ideas de Vigotsky y predominan entre ellos una visión simplista acerca de las dinámicas humanas que propicia entre los investigadores una visión monolítica a la vez que conformista sobre estos temas. En el presente artículo, analizo críticamente las tergiversaciones principales, que a mi juicio, ha sufrido el enfoque histórico cultural y sus causas. Por otra parte, razono la esencia humanista y compleja del paradigma histórico culturalista y su valor explicativo, lo que tiene que ver con las incomprensiones tratadas aquí. El positivismo evade de cierta forma el estudio de los fundamentos teóricos de los enfoques. Mi objetivo fundamental es esclarecer la lógica vigotskyana (consistente en un punto de vista dialéctico complejo en oposición con la filosofía positivista. Finalmente, valoro una investigación que considero como uno de los mejores ejemplos de la visión histórico culturalista sobre la educación y el desarrollo. Enfatizo dos conclusiones fundamentales del análisis: Primero: la tarea principal que tiene un lector para comprender la obra de un autor en el ámbito del desarrollo humano -como es el caso de Vigotsky-, es comprender su axiología y epistemología. En segundo lugar, que ese razonamiento permite conocer verdaderamente el fundamento en que se sustentan las categorías y principios asumidos. Ambos pasos están ligados indisolublemente. El lector tiene que considerar la idiosincrasia del autor, su modo de pensar y su carácter, desde el comienzo de la lectura.

Social isolation has a multitude of negative consequences on human health including the ability to endure challenges to the immune system, sleep amount and efficiency, and general morbidity and mortality. These adverse health outcomes are conserved in other social species. In the fruit fly Drosophila melanogaster, social isolation leads to increased aggression, impaired memory, and reduced amounts of daytime sleep. There is a correlation between molecules affected by social isolation and those implicated in sleep in Drosophila. We previously demonstrated that acute sleep loss in flies and mice induced the unfolded protein response (UPR), an adaptive signaling pathway. One mechanism indicating UPR upregulation is elevated levels of the endoplasmic reticular chaperone BiP/GRP78. We previously showed that BiP overexpression in Drosophila led to increased sleep rebound. Increased rebound sleep has also been demonstrated in socially isolated (SI) flies. D. melanogaster were used to study the effect of social isolation on cellular stress. SI flies displayed an increase in UPR markers; there were higher BiP levels, increased phosphorylation of the translation initiation factor eIF2α, and increased splicing of xbp1. These are all indicators of UPR activation. In addition, the effects of isolation on the UPR were reversible; pharmacologically and genetically altering sleep in the flies modulated the UPR. The reduction in sleep observed in SI flies is a cellular stressor that results in UPR induction. © Sleep Research Society 2017.

Hydrology and climate of four watersheds in eastern Puerto Rico: Chapter C in Water quality and landscape processes of four watersheds in eastern Puerto Rico

Puerto Rico lies directly in the path of the easterly trade winds, which deliver steady rainfall to the mountains and steer tropical wave systems toward the island. Hurricanes and tropical storms derived from these tropical waves differ in frequency and intensity, contributing to substantial interannual variation in precipitation and stream discharge. Puerto Rico's steep topography and small water-storage capacity leave the island's water supply and developed flood plains vulnerable to extreme weather events, such as hurricanes, floods, and droughts. This vulnerability may increase in the future owing to ongoing change, both local (such as land-cover shifts, water-supply projects, and construction of roads and other infrastructure) and regional (climate variability and change). Climate change, which could lead to more intense and prolonged droughts as well as an increase in the magnitude and frequency of destructive storms in the Caribbean, may alter temperature and affect the availability of water for human and ecosystem needs. Accurate assessment of hydrologic regimes and water budgets is therefore crucial for effective management of water resources. As part of the U.S. Geological Survey's Water, Energy, and Biogeochemical Budgets program, hydrologic and geomorphologic processes and stream chemistry of four small watersheds in eastern Puerto Rico, which differ in geology and land cover, have been studied since 1991. Spatial and temporal characteristics of precipitation and stream discharge, along with water budgets, were determined for the watersheds for the period 1991 to 2005. The locations of the watersheds relative to the Luquillo Mountains and the range's associated rain shadow dominate hydrological processes, dwarfing influences of land cover. The influence of geology is reflected in recession characteristics of the rivers (recession is faster in soils overlying volcaniclastic bedrock) and in hillslope geomorphic processes (sediment is delivered at higher
