Signo y Pensamiento , 2006,
Abstract: this article makes a general introduction of the premises, both theoretical and historical, from which the research on "colombian modernity as narrated by publicity: 1900-1950" was carried out. among such premises are the debate on the role of publicity in building colombian modernity, and the analysis of the function of the calculation - need - desire trilogy in consumer decision making. finally, the methodological design is presented along with some partial results and conclusions.
Diversification of Two Lineages of Symbiotic Photobacterium
Henryk Urbanczyk, Yoshiko Urbanczyk, Tetsuya Hayashi, Yoshitoshi Ogura
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0082917
Abstract: Understanding of processes driving bacterial speciation requires examination of closely related, recently diversified lineages. To gain an insight into diversification of bacteria, we conducted comparative genomic analysis of two lineages of bioluminescent symbionts, Photobacterium leiognathi and ‘P. mandapamensis’. The two lineages are evolutionary and ecologically closely related. Based on the methods used in bacterial taxonomy for classification of new species (DNA-DNA hybridization and ANI), genetic relatedness of the two lineages is at a cut-off point for species delineation. In this study, we obtained the whole genome sequence of a representative P. leiognathi strain lrivu.4.1, and compared it to the whole genome sequence of ‘P. mandapamensis’ svers.1.1. Results of the comparative genomic analysis suggest that P. leiognathi has a more plastic genome and acquired genes horizontally more frequently than ‘P. mandapamensis’. We predict that different rates of recombination and gene acquisition contributed to diversification of the two lineages. Analysis of lineage-specific sequences in 25 strains of P. leiognathi and ‘P. mandapamensis’ found no evidence that bioluminescent symbioses with specific host animals have played a role in diversification of the two lineages.

Urbanczyk,Maria; Hernández,Yesid Fernando;
Palabra Clave , 2012,
Abstract: the main interest of the article focuses on evidencing the narratives of violence, reflected in the audiovisual works of college students who, through their exclusive sensibilities, make valuable contributions to the construction and preservation of the country's memory. seven fiction-short films in six educational centers nationwide are being analyzed, whose participation in the ventanas audiovisual sample has been the most significant because of the quality of the work presented from the perspective of theme esthetic treatment of violence.
Ex Utero intrapartum treatment (EXIT)  [PDF]
Srinivas Pentyala, Aleef Rahman, Pooja Mysore, Sahana Pentyala, Kyle Urbanczyk, Thomas Tumillo, John Muller, Yimei Miao, Sardar Khan
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.39A007
Abstract:

The anesthesia ex utero intrapartum treatment (EXIT) procedure is a specialized surgical procedure used to deliver babies who have airway compression due to cystic adenomatoid malformation, bronchopulmonary sequestration, cervical teratomas, or other congenital conditions. EXIT is erroneously known as a routine cesarean section (CS), but is rather an extension of CS with discernible differences. The procedure creates an opening in the anesthetized abdomen of the mother and uterus. Once EXIT is complete, the remainder of the CS proceeds. EXIT is much more complex than a routine CS, as it requires coordination between the mother and a multidisciplinary team of surgical and neonatal personnel. This review highlights current anesthetic concepts during the EXIT procedure.

Monitoring Recreational Waters: How to Integrate Environmental Determinants  [PDF]
Patricia Turgeon
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.328095
Abstract: Recreational waters are associated with a higher risk of disease for people engaged in activities that bring them into contact with these waters. The primary cause of contamination of recreational waters is fecal microorganisms, which may originate from various sources and involve several modulating factors, making it a complex public health and en- vironmental issue. Monitoring recreational water quality should include two key components: Microbial water testing and monitoring environmental determinants associated with higher risks of contamination. Conducting both activities provides the foundation for a comprehensive assessment according to risk and the actual level of fecal pollution and thus could promote good management actions to ensure safe water quality. Nevertheless, monitoring of environmental determinants is rarely fully integrated in monitoring programs and is also harder to achieve, especially when water pol- lution is mainly associated with nonpoint sources. In order to achieve identification and monitoring of environmental determinants associated with fecal contamination of recreational waters, some specific steps should be followed and some questions must be answered. The objective of this review article is to present current knowledge on this topic and to suggest and discuss recommendations. Potential sources of contamination and factors able to modulate them should be identified and measured after the geographical area influencing fecal contamination of recreational water has been delineated. Statistical models have been developed to identify the relative importance of these environmental characteristics on fecal pollution of recreational waters but they do not allow for a full comprehension of the exact processes leading to this pollution, thus other methods should also be used to better understand these processes.
Availability and accessibility of diabetes clinics on Trinidad: An analysis using proximity tools in a GIS environment  [PDF]
Patricia Boda
Health (Health) , 2013, DOI: 10.4236/health.2013.511A2006
Abstract:

Non-communicable diseases (NCDs), account for a growing number of deaths worldwide. The English-speaking Caribbean has the highest per capita burden of NCDs in the region of the Americas [1]. This paper presents an overview of availability and accessibility based on clinic hours and physician fulltime equivalents (FTE) on the island of Trinidad devoted to diabetes and wound care. The project integrates a Geographic Information System (GIS) with epidemiologic and bio-statistical data to provide a necessary spatial analysis not otherwise possible. It examines the island’s ability to effectively deliver treatment to residents with diabetes by providing a geographic perspective to data published on the internet by the Trinidad-Tobago Ministry of Health and the Central Statistical Office. Results indicate a significant regional variability in both numbers of physicians and office hours devoted to diabetes treatment.

Design of Antimicrobially Active Small Amphiphilic Peptide Dendrimers
Piotr Polcyn,Margarita Jurczak,Aleksandra Rajnisz,Jolanta Solecka,Zofia Urbanczyk-Lipkowska
Molecules , 2009, DOI: 10.3390/molecules14103881
Abstract: Novel polyfunctional small amphiphilic peptide dendrimers characterized by incorporation of a new core compounds – tris-amino acids or tetrakis-amino alcohols that originated from a series of basic amino acids – were efficiently synthesized. These new core elements yielded molecules with multiple branching and (+5)/(+6) charge at the 1-st dendrimer generation. Dendrimers exhibited significant antimicrobial potency against Gram(+) and Gram(-) strains involving also multiresistant reference strains (S. aureus ATCC 43300 and E. coli ATCC BAA-198). In addition, high activity against fungi from the Candida genus was detected. More charged and more hydrophobic peptide dendrimers expressed hemolytic properties.
Spectral-Domain Measurement of Strain Sensitivity of a Two-Mode Birefringent Side-Hole Fiber

Sensors , 2012, DOI: 10.3390/s120912070
Abstract: The strain sensitivity of a two-mode birefringent side-hole fiber is measured in the spectral domain. In a simple experimental setup comprising a broadband source, a polarizer, a two-mode birefringent side-hole fiber under varied elongations, an analyzer and a compact spectrometer, the spectral interferograms are resolved. These are characterized by the equalization wavelength at which spectral interference fringes have the highest visibility (the largest period) due to the zero group optical path difference between the fundamental, the LP01 mode and the higher-order, the LP11 mode. The spectral interferograms with the equalization wavelength are processed to retrieve the phase as a function of the wavelength. From the retrieved phase functions corresponding to different elongations of a two-mode birefringent side-hole fiber under test, the spectral strain sensitivity is obtained. Using this approach, the intermodal spectral strain sensitivity was measured for both x and y polarizations. Moreover, the spectral polarimetric sensitivity to strain was measured for the fundamental mode when a birefringent delay line was used in tandem with the fiber. Its spectral dependence was also compared with that obtained from a shift of the spectral interferograms not including the equalization wavelength, and good agreement was confirmed.
On the Antimicrobial Activity of Various Peptide-Based Dendrimers of Similar Architecture
Tania K. Lind,Piotr Polcyn,Paulina Zielinska,Marité Cárdenas,Zofia Urbanczyk-Lipkowska
Molecules , 2015, DOI: 10.3390/molecules20010738
Abstract: Antimicrobial drug resistance is a major human health threat. Among the many attempts to tackle this problem, the synthesis of antimicrobial compounds that mimic natural antimicrobial peptides appears as a promising approach. Peptide-based dendrimers can be designed to have higher potency than natural antimicrobial peptides and at the same time they can evade the bacterial defense system. Novel dendrimers with similar chemical structure but varying potency in terms of minimum inhibitory concentration were designed. The dependency between dendrimer structure and antibacterial activity as well as their capacity to attack model cell membranes was studied. The data suggests that supramolecular structure in terms of charge distribution and amphiphilicity, rather than net charge, is the main driver for disruption of cellular membranes and this correlates well with dendrimer hemolytic activity.
