Expression and function of macrophage migration inhibitory factor (MIF) in melioidosis.

BACKGROUND: Macrophage migration inhibitory factor (MIF) has emerged as a pivotal mediator of innate immunity and has been shown to be an important effector molecule in severe sepsis. Melioidosis, caused by Burkholderia pseudomallei, is an important cause of community-acquired sepsis in Southeast-Asia. We aimed to characterize the expression and function of MIF in melioidosis. METHODOLOGY AND PRINCIPAL FINDINGS: MIF expression was determined in leukocytes and plasma from 34 melioidosis patients and 32 controls, and in mice infected with B. pseudomallei. MIF function was investigated in experimental murine melioidosis using anti-MIF antibodies and recombinant MIF. Patients demonstrated markedly increased MIF mRNA leukocyte and MIF plasma concentrations. Elevated MIF concentrations were associated with mortality. Mice inoculated intranasally with B. pseudomallei displayed a robust increase in pulmonary and systemic MIF expression. Anti-MIF treated mice showed lower bacterial loads in their lungs upon infection with a low inoculum. Conversely, mice treated with recombinant MIF displayed a modestly impaired clearance of B. pseudomallei. MIF exerted no direct effects on bacterial outgrowth or phagocytosis of B. pseudomallei. CONCLUSIONS: MIF concentrations are markedly elevated during clinical melioidosis and correlate with patients' outcomes. In experimental melioidosis MIF impaired antibacterial defense.

Descartes wears Converse: Liberal Arts for the Twenty-First Century Student

Students today have a different way of relating to information due to the new media channels that have arisen in the last decades. These have changed the way high-school and undergraduate students learn and they have altered the manner by which they perceive the world. Today’s Education Theory must take this fact into account in order to enhance the student’s learning process. The objective of this project is to give an example of how this enhancement may be achieved. First, it will give a brief overview of the relation between today’s young generations and the different channels of information; secondly, it will analyze the cognitive, psychological and educational theories that explain how the human brain learns and the important value that nonverbal information has for the memory system; afterwards, it will focus on this nonverbal information, looking at the possible effects that it may have on human memory and learning; finally, it will give an example of the practical implementation of this theory through the presentation of three animated instructional videos that have been created with the specific aim of enhancing the young generation’s understanding of some complex subjects of the Liberal Arts.

The Catalan migration to New York. A view from La Llumanera de Nova York (1874-1881)

The first issue of La Llumanera de Nova York came out in November 1874 and was not published until 1881. The challenge was certainly complicated: editing a newspaper in Catalan in New York, with the aim of influencing a group of potential readers who were distributed in the United States and, at the same time, become a medium that would bring the ideas of a new era, both from a political and cultural point of view

Student Loans: A Guide For Students and Parents

2015-16 Student Loan Repayment and Forgiveness Programs

Many loan repayment and incentive programs are available to encourage college students and graduates to enter into and continue to work in designated high-need careers. More and more Iowans are reaping the rewards of these federal, state and private programs that help reduce student loan debt while allowing them to pursue their career goals. Some programs make payments directly to the recipient’s student loan servicer to reduce the balance owed (loan repayment), while others may provide the option of an income stipend or bonus for eligible recipients who meet specified employment and other criteria. This guide provides information on many of the federal and state loan repayment and incentive programs currently available.

Beyond Conditionality versus Cooperation: Power and Resistance in the Case of EU Mobility Partnerships and Swiss Migration Partnerships

Migration partnerships (MPs) have become a key instrument in global migration governance. In contrast to traditional unilateral approaches, MPs emphasize a more comprehensive and inclusive tackling of migration issues between countries of origin, transit, and destination. Due to this cooperation-oriented concept, most of the existing studies on MPs neglect power questions within partnerships in line with the official discourse, reflecting a broader trend in the international migration governance literature. Others take an instrumentalist view in analysing the power of partnerships or focus on soft power. Illustrated with the examples of the European Mobility Partnerships (EU MPs) and the Swiss Migration Partnerships (CH MPs), we conduct an analysis based on a concept of productive power drawing on post-structural and post-colonial insights. Our main argument is that in contrast to their seemingly consent-oriented and technical character, MPs are sites of intense (discursive) struggles, and (re-)produce meanings, subjects, and resistances. A productive power analysis allows us to move beyond the dichotomy in the literature between coercion and cooperation, as well as between power and resistance more broadly.

Long-term and long-range migration of radioactive fallout in a Karst system.

Mountainous areas are often covered by little evolved soils from which deposited radionuclides can potentially leak into the vadose zone. In the Swiss Jura mountains, we observed unusual isotopic ratios of nuclear weapon test (NWTs) fallout with an apparent loss of NWTs plutonium relative to &supl;³⁷Cs of Chernobyl origin in thinner soils. Here, we studied the karstic watershed of a vauclusian spring to determine the residence times of plutonium, ²⁴&supl;Am, and ⁹⁰Sr deposited by global fallout and their respective mobility in carbonaceous soils. The results show that ⁹⁰Sr is washed most efficiently from the watershed with a residence time of several hundred years. The estimated plutonium residence time is more than 10 times higher (in the range of 5000-10,000 years), and the ²⁴&supl;Am residence time is double that of plutonium. The spring water ²⁴&supl;Am/²³⁹+²⁴⁰Pu isotopic ratio is lower (0.12 - 0.28) than found in watershed soils (0.382 ± 0.077). Similar differences are found in aquatic mosses (²⁴&supl;Am/²³⁹+²⁴⁰Pu isotopic ratio 0.05-0.12), which are permanently submerged in spring waters. In contrast to plutonium, ⁹⁰Sr is leached from these mosses with 0.5M HCl, demonstrating that strontium is probably associated with calcium carbonate precipitations on the mosses. The higher plutonium to americium isotopic ratio found in the samples of spring water and mosses at the outlet of the karst shows that plutonium mobility is enhanced.

Increased macrophage migration inhibitory factor (MIF) plasma levels in acute HIV-1 infection.

Considering macrophage migratory inhibitory factor (MIF) as a critical pro-inflammatory cytokine of the immune system, we evaluated plasma MIF levels in 89 HIV-infected adults. Plasma MIF levels were higher in HIV-infected than in HIV-negative individuals. Highest MIF levels were observed during acute HIV infection (AHI) whilst patients on antiretroviral therapy (ART) had lower MIF levels, regardless of ART efficacy. Our results suggest that MIF is an integral component of the cytokine storm characteristic of AHI.
