Plos Pathogens : Escape. in Each of the Subjects, Nabs Targeted Different Regions of the Hiv-1 Envelope Env in a Strain-specific,, Volume No. 6

By: Andrew P. Rice

Description : Apoptosis in HIV-1-infected CD4+ primary T cells is triggered by the alteration of the PI3K and p53 pathways, which converge on the FOXO3a transcriptional activator. Tat alone can cause activation of FOXO3a and of its proapoptotic target genes. To understand how Tat affects this pathway, we carried out ChIP-Chip experiments with Tat. Tat associates with the promoters of PTEN and two PP2A subunit genes, but not with the FOXO3a promoter. PTEN and PP2A encode phosphatases, whose levels and activity are increased when Tat is expressed. They counteract phosphorylation of Akt1 and FOXO3a, and so activate transcriptional activity of FOXO3a. FOXO3a promotes increased transcription of Egr-1, which can further stimulate the transcription of PTEN, thereby reinforcing the pathway that leads to FOXO3a transcriptional activation. RNAi experiments support the role of PTEN and PP2A in the initiation of the Tat-mediated cascade, which is critical to apoptosis. The increased accumulation of PTEN and PP2A subunit mRNAs during Tat expression is more likely to be the result of increased transcription initiation and not relief of promoter-p...

Institutions and the Losses from Natural Disasters : Volume 8, Issue 4 (01/07/2008)

By: P. A. Raschky

Description: Institute of Public Finance, University of Innsbruck, Universitaetsstrasse 15, A-6020 Innsbruck and alpS – Center for Natural Hazard Management, Innsbruck, Austria. Natural hazards can be seen as a function of a specific natural process and human (economic) activity. Whereby the bulk of literature on natural hazard management has its focus on the natural process, an increasing number of scholars is emphasizing the importance of human activity in this context. Existing literature has identified certain socio-economic factors that determine the impact of natural disasters on society. The purpose of this paper is to highlight the effects of the institutional framework that influences human behavior by setting incentives and to point out the importance of institutional vulnerability. Results from an empirical investigation of large scale natural disasters between 1984 and 2004 show that countries with better institutions experience less victims and lower economic losses from natural disasters. In addition, the results suggest a non-linear relationship between economic development and economic disaster ...

The Crisis in Russia

By: Arthur Ransome

Introduction: The characteristic of a revolutionary country is that change is a quicker process there than elsewhere. As the revolution recedes into the past the process of change slackens speed. Russia is no longer the dizzying kaleidoscope that it was in 1917. No longer does it change visibly from week to week as it changed in 19l8. Already, to get a clear vision of the direction in which it is changing, it is necessary to visit it at intervals of six months, and quite useless to tap the political barometer several times a day as once upon a time one used to do....But it is still changing very fast. My journal of ......

Tombstone Epitaph : May 1916

By: Reppy & Peck

Description: The Tombstone Epitaph took its first breath of life in 1880 as a Republican paper under the operation of John P. Clum, Thomas Sorin, and later that year, Charles Reppy. Clum chose the name for the paper because he felt that every tombstone had to have an epitaph. According to William H. Lyon, in his book, Those Old Yellow Dog Days, Frontier Journalism in Arizona 1859-1912, Clum’s friends “thought the name alone would kill the paper,” yet “Clum took pride in his morbid creation” and felt that the Tombstone Epitaph would serve as a journal which represented and built up mining, Tombstone’s founding industry. In 1881, as postmaster and mayor of Tombstone, as well as the editor and publisher of the Epitaph, Clum ventured farther into politics with a self-proclaimed goal of ridding the town of corruption while creating peace and wealth for its citizens. One of his first orders of business was addressing what he called “the county ring,” a group of crooked officials and local ranchers who Clum claimed were allied with outlaw elements. This alleged alliance served to fracture the town of Tombstone, resulting in the formation o...

Relative Roles of Endolithic Algae and Carbonate Chemistry Variability in the Skeletal Dissolution of Crustose Coralline Algae : Volume 11, Issue 2 (24/02/2014)

By: S. Dove; G. Diaz-pulido; C. Reyes-nivia

Description: School of Biological Sciences and Australian Research Council Centre of Excellence for Coral Reef Studies, University of Queensland, St. Lucia, Queensland 4072, Australia. The susceptibility of crustose coralline algae (CCA) skeletons to dissolution is predicted to increase as oceans warm and acidify. Skeletal dissolution is caused by bioerosion from endolithic microorganisms and by chemical processes associated with undersaturation of carbonate minerals in seawater. Yet, the relative contribution of algal microborers and seawater carbonate chemistry to the dissolution of organisms that cement reefs under projected CO2 and temperature (CO2-T) scenarios have not been quantified. We exposed CCA skeletons (Porolithon onkodes) to four CO2-T treatments (pre-industrial, present-day, SRES-B1 reduced CO2 emission scenario, SRES-A1FI business-as-usual CO2 emission scenario) under natural light cycles vs. constant dark conditions for 8 weeks. Dissolution rates of skeletons without photo-endoliths were dramatically higher (200%) than those co...

Plos One : Lactobacillus Reuteri Dsm 17938 Changes the Frequency of Foxp3+ Regulatory T Cells in the Intestine and Mesenteric Lymph Node in Experimental Necrotizing Enterocolitis, Volume 7

By: Valli De Re

Description : Necrotizing enterocolitis (NEC) is an inflammatory disease of the intestine in premature infants. Lactobacillus reuteri DSM 17938 improves survival and reduces the incidence and severity of NEC in a rodent model. Foxp3+ regulatory T cells (Tregs) maintain intestinal homeostasis by controlling inflammation and inducing tolerance. To determine whether there are insufficient numbers of Tregs to control inflammation in NEC and to determine if LR17938 increases the frequency of Tregs, we studied selected groups of newborn Sprague-Dawley rats according to feeding plan : dam6LR17938, formula6LR17938, and NEC6LR17938. NEC was induced by gavage feeding with special formula and exposure to hypoxic conditions. Lymphocytes isolated from ileum, mesenteric lymph nodes (MLN), spleen and thymus were labeled for T cell surface markers (CD3, CD4, CD8) and intracellular Foxp3: and labeled cells were analyzed by flow cytometry. The percentage of CD3+ T cells and Foxp3+ Tregs in the ileum significantly decreased in pups with NEC, compared to normal controls. Feeding LR17938 to neonatal rats with NEC increased the % of Foxp3+ T cells in the...

Are Lifetime Abstainers the Best Control Group in Alcohol Epidemiology? on the Stability and Validity of Reported Lifetime Abstention., Vol. 168

By: Ye, Y.

Description: This article is from American Journal of Epidemiology, volume 168.

Abstract

Lifetime abstainers have often been recommended as the comparison group in alcohol epidemiology. The objective of this study was to provide insight into the validity and stability of lifetime abstention by using data derived from the National Alcohol Survey, a national probability survey of US households conducted in 1984, and its 2 follow-up surveys conducted in 1990 and 1992. Results indicated that more than half (52.9%; all proportions were weighted to represent the US population) of those who reported never having a drink of any alcoholic beverage in the 1992 survey reported drinking in previous surveys. Depending on assumptions, this difference may result in an underestimation of alcohol-attributable mortality of 2%−15% in men and 2%−22% in women. Sociodemographic factors differe...
