Poverty Reduction and the Income Inequality in China

In 2000, the United Nations adopted the Millennium Development Goals which set targets for raising living standards in low-income countries. The first goal was to “eradicate extreme poverty and hunger” (United Nations). The World Bank defines extreme poverty as income of less than $1.25 per day (World Bank, 2010a). Based on this definition, the World Bank estimates that the percentage of the population in China living in extreme poverty has fallen from 84 percent in 1981 to about 16 percent in 2005, a period during which China’s population grew by more than 300 million people (see Table 1 on last page). Because China is a very large country with a current population approaching 1.4 billion (more than four times the United States population), its dramatic reduction in poverty over the past 30 years has had a profound effect on global poverty measures. In fact, poverty reduction in China is the main reason that the incidence of extreme poverty in developing countries has fallen from about 52 percent in 1981 to 25 percent in 2005 (Table 1). While the absolute number of poor in China fell by some 627 million, the number of poor in other developing countries actually grew slightly (from 1,065 million to 1,166 million). These figures represent a decline in the percentage of the total population in poverty in other developing countries because of general population growth over that 25-year period (World Bank, 2010b).

Bakhtin e o grupo: incongruências de uma linguística ortodoxa

For these Russian authors, a sign has to be faithful to reality but what is, in fact, «to be faithful», what is «reality»? They suggest that thought structures itself only by means of signs – as Peirce, who denies the reality of dreams saying that the act to feel hunger is an ideological expression and the shouts of a new-born are already appreciative manifestations of this new human being. The authors had inspired the structuralism, saying that a «semiodiscourse» structures men. Although this instance, word remains neutral, assertion strange to their Hegelian and Marxist roots; their paradigm in contrast, can be Heideggerian, according to which, only the «marked» being exists: looking at one determined thing, I place it, I fit it in its context. To place something is to attribute sense and that is more Stoic than, in fact, Marxist.

Emission of Methane by Eudrilus eugeniae and Other Earthworms from Brazil

Earthworms emit denitrification-derived nitrous oxide and fermentation-derived molecular hydrogen. The present study demonstrated that the earthworm Eudrilus eugeniae, obtained in Brazil, emitted methane. Other worms displayed a lesser or no capacity to emit methane. Gene and transcript analyses of mcrA (encoding the alpha subunit of methyl-CoM reductase) in gut contents of E. eugeniae suggested that Methanosarcinaceae, Methanobacteriaceae, and Methanomicrobiaceae might be associated with this emission.

Parathyroid adenoma apoplexy as a temporary solution of primary hyperparathyroidism: a case report

Abstract Introduction The natural history of patients with spontaneous parathyroid necrosis is unknown. In this case report we describe the clinical course, laboratory, radiographic, bone densitometry tests, parathyroid ultrasonography and scintigraphy examinations of a patient performed over a period of eight years after she first presented with a sudden episode of spontaneous resolution of primary hyperparathyroidism (PHPT). Case presentation A 24-year-old woman with a clinical history and laboratory and radiographic tests compatible with PHPT suffered a sudden episode of cervical pain and presented with clinical evidence of hypocalcemia. Biopsy of a cervical nodule revealed necrotic material compatible with ischemia of the parathyroid. The follow-up of the patient presented four distinct phases: the first, which lasted two years, was compatible with a period of bone hunger during which it was necessary to introduce calcitriol and calcium carbonate. During this period, the patient showed bone mass gain. The second phase was characterized by normalization of calcium and parathyroid hormone levels and its end was difficult to define. During the third phase there was a recurrence of hypercalcemia associated with elevated parathyroid hormone (PTH) levels and loss of bone mass. The last phase corresponded to the interval after parathyroidectomy, which was characterized by normalization of serum levels of calcium and PTH, as well as bone mass gain. Conclusion This case report indicates that spontaneous resolution of PHPT by adenoma necrosis is potentially temporary. Thus, in cases in which a conservative approach is chosen, clinical and laboratory follow-up is indispensable. Bone mass measurement is a useful tool in the follow-up of these cases. However, this option exposes the patient to a potential roller-coaster ride of bone mass gain and loss, whose long term consequences are still unknown.

Neuropeptide und die Regulation des Kohlenhydratstoffwechsels im Fettkörper der Argentinischen Schabe (Blaptica dubia)

Trehalose ist der Hauptblutzucker in der Hämolymphe der meisten Insekten. Trehalose wird im Fettkörper synthetisiert, dem wichtigsten Organ des Intermediärstoffwechsels bei Insekten. Wie die Homöostase des Blutzuckers reguliert wird, ist nicht vollständig geklärt. Die Produktion von Trehalose erfordert eine grundlegende Umschaltung im Stoffwechsel des Fettkörpers, die mehrere wichtige Stoffwechselwege betrifft, so dass die Fettkörperzellen (Trophocyten) von der Speicherung und Katabolisierung von Zucker zur Mobilisierung von Reservestoffen (Glykogen, Fett, Protein) und Trehalosesynthese umschalten. Am Fettkörper und isolierten Trophocyten der Argentinischen Schabe (Blaptica dubia) wurden Stoffwechseleffekte und Elemente der Signalkette des hypertrehalosämischen Hormons Bld HrTH untersucht. Inkubation isolierter Fettkörperloben mit Bld HrTH verringerte innerhalb von 60 min den Glykogengehalt (um 13,4 %) und steigerte die Konzentration der Hexosephosphate Glucose-6-phosphat und Fructose-6-phosphat, die Substrat sowohl für die Trehalosesynthese als auch für die Glykolyse sind. Pyruvat, Glycerin-3-phosphat, Citrat und insbesondere Fructose-1,6-bisphosphat (+750 %) waren ebenfalls erhöht. Der Glykolyseaktivator/Gluconeogeneseinhibitor Fructose-2,6-bisphosphat wird durch Bld HrTH vermindert. Da Trehalosesynthese und Glykolyse um dieselben Substrate (Glucosephosphate) konkurrieren, fördert der hormoninduzierte Abfall des Glykolyseaktivators Fructose-2,6-bisphosphat die Trehalogenese.Es ist gelungen, Trophocyten zu isolieren und die Signaltransduktion von Bld HrTH an einheitlichen Zellen und auch an Einzelzellen zu studieren. Hauptziel dieser Arbeit war es, die Funktion von Ca2+ im Signalweg des Bld HrTH genauer zu untersuchen. Die isolierten Zellen reagierten auf das Neuropeptid mit einer deutlichen Steigerung der Trehalosesynthese (+133,7 %) und einer Senkung des Fructose-2,6-bisphosphat-Gehaltes (-30,2 %). Sie bieten somit ein geeignetes System zur Untersuchung der Wirkungsmechanismen von Bld HrTH auf zellulärem Niveau. Ca2+ aus dem Extrazellulärraum und aus intrazellulären Speichern spielen bei der Signaltransduktion eine Rolle. Während extrazelluläres Ca2+ insbesondere für die Senkung des Fructose-2,6-bisphosphat-Gehaltes wichtig war, wurde Ca2+ aus zellulären Speichern insbesondere für die Trehalosesynthese benötigt, wobei sich jedoch beide Wege wechselseitig beeinflussen. Erstmals konnten an isolierten Trophocyten Änderungen von Ca2+ mikrofluorometrisch an Einzelzellen studiert werden. Das hypertrehalosämische Hormon ruft einen schnellen und starken Anstieg der intrazellulären Ca2+-Konzentration ([Ca2+]i) hervor. Die Untersuchungen deuten auf einen Signalweg über IP3 und Diacylglycerin hin, entsprechend der Phosphoinositidkaskade. Eine Beteiligung des biogenen Amins Octopamin, von cAMP oder von Stickstoffmonoxid (NO) an der Signaltransduktion scheint hingegen unwahrscheinlich. Der Zuckergehalt im Medium scheint ebenfalls auf die Trehalogenese zu wirken. Bei hohen Konzentrationen von Glucose oder Trehalose wurde eine Hemmung der Trehalosesynthese beobachtet, die als Rückkopplungshemmung gedeutet werden kann. Bei Hunger wird das im Fettkörper gespeicherte Glykogen stark reduziert. Außerdem scheint die Zahl der symbiontischen Mikroorganismen in den Mycetocyten verringert.

Determinants of child undernutrition in India. A micro-case study to operationalize the Capability Approach

The present research aims at shedding light on the demanding puzzle characterizing the issue of child undernutrition in India. Indeed, the so called ‘Indian development paradox’ identifies the phenomenon according to which higher level of income per capita is recorded alongside a lethargic reduction in the proportion of underweight children aged below three years. Thus, in the time period occurring from 2000 to 2005, real Gross Domestic Production per capita has annually grown at 5.4%, whereas the proportion of children who are underweight has declined from 47% to 46%, a mere one point percent. Such trend opens up the space for discussing the traditionally assumed linkage between income-poverty and undernutrition as well as food intervention as the main focus of policies designed to fight child hunger. Also, it unlocks doors for evaluating the role of an alternative economic approach aiming at explaining undernutrition, such as the Capability Approach. The Capability Approach argues for widening the informational basis to account not only for resources, but also for variables related to liberties, opportunities and autonomy in pursuing what individuals value.The econometric analysis highlights the relevance of including behavioral factors when explaining child undernutrition. In particular, the ability of the mother to move freely in the community without the need of asking permission to her husband or mother-in-law is statistically significant when included in the model, which accounts also for confounding traditional variables, such as economic wealth and food security. Also, focusing on agency, results indicates the necessity of measuring autonomy in different domains and the need of improving the measurement scale for agency data, especially with regards the domain of household duties. Finally, future research is required to investigate policy venues for increasing agency in women and in the communities they live in as viable strategy for reducing the plague of child undernutrition in India.

Induktion von Pro-Autophagie-Signalen durch einen extra- oder intrazellulären Alpha-Toxin-Angriff

Autophagie ist ein konservierter, kataboler Mechanismus in allen eukaryoten Zellen. Unter anderem wird ihm eine wichtige Rolle als zellautonomer Abwehrmechanismus gegen Mikroorganismen zugeschrieben; von manchen Infektionserregern wird er jedoch unterlaufen oder sogar genutzt. Der stärkste Auslöser der Autophagie ist ein Mangel an Nährstoffen, insbesondere Aminosäuren. Über die Deaktivierung der Kinase mTORC1 und die Phosphorylierung des eukaryoten Translationsinitiationsfaktors eIF2α hemmt die Nährstoffknappheit die Proteinbiosynthese und aktiviert gleichzeitig Autophagie. Wie Mikroorganismen, insbesondere Bakterien, Autophagie auslösen oder manipulieren, ist derzeit Gegenstand intensiver Forschung. Modifikationen an Mikroben oder Phagosomen und Adapterproteine, die diese Veränderungen und Komponenten des Autophagieapparates erkennen, scheinen jedenfalls bei der selektiven Erkennung durch die Autophagie-Maschinerie wichtig zu sein. rnIn der vorliegenden Dissertationsarbeit wird die Rolle des membranporenbildenden α-Toxins von Staphylococcus aureus für die Induktion von Autophagie beleuchtet. Zum einen erwies sich die Akkumulation von (EGFP)-LC3(II), einem Marker der Autophagosomen, um intrazelluläre S. aureus als abhängig von α-Toxin. Zweitens, genügt extrazellulär appliziertes α-Toxin um (EGFP)-LC3(II)-positive Endosomen zu induzieren. Während der Angriff aus dem extrazellulären Raum jedoch binnen kurzer Zeit eine fokale Kumulation von phosphoryliertem eIF2α an der Plasmamembran induziert, die an der Internalisierung des Toxins beteiligt ist, findet sich am phagosomalen Kompartiment keine Toxin-abhängige Anhäufung von p-eIF2α oder proximalen Autophagieregulatoren. Dies impliziert, dass Toxin-Angriff auf die Plasmamembran, nicht aber auf das Phagosom, zu einer Reaktion führt, wie sie bei massivem Nährstoffmangel zu beobachten ist. Obwohl keine α-Toxin-abhängige Kumulation von p-eIF2α bei einem Angriff aus dem Phagosom erfolgt, findet sich um α-Toxin-produzierende Bakterien eine massive Kumulation von LC3 und Adapterprotein p62/Sequestosome1. Dies deutet daraufhin, dass der Ort des Angriffs - Plasmamembran oder Phagosom – für den Autophagie-induzierenden Mechanismus wichtig sein könnte. Der unterschiedliche Effekt auf die zellulären Ionenkonzentrationen, den ein Angriff auf die Plasmamembran oder auf ein Phagosom auslösen würde, bietet hierfür eine mögliche Erklärung. Die Aktivierung der Autophagie über Adapterproteine könnte dann als back-up Mechanismus fungieren, der auch dann greift, wenn eine Invasion ohne Schädigung der Plasmamembran erfolgt. Ein cross-talk der beiden Induktionswege ist angesichts der Bedeutung von p62 für die selektive und die Hunger-assoziierte Autophagie gut möglich; sezerniertes Toxin könnte durch die Aktivierung der basalen Autophagie Adapter-basierte Mechanismen verstärken.

Talking through walls: a history of the murals in Northern Ireland

This dissertation examines how some fundamental events of the history of Ireland emerge through the art of the mural. It is divided into three chapters. The first chapter opens with a brief presentation of the mural as a form of art with a semiotic and sociological function, with a particular focus on the socio-political importance it has had and still has today in Ireland, where murals are a significant means of expressing ideals, protest and commemoration. A part of this chapter also provides data about the number of murals and their location, with a particular focus on the two cities of Belfast and Derry. This first chapter ends with the presentation of an initiative put forth by the Arts Council of Northern Ireland, called "Building Peace through the Arts: Re-Imaging Communities", and questions its implementation on the Irish soil. The second chapter provides a history of the murals in Northern Ireland, from the Unionist's early depictions of King Billy in occasion of the 12 July annual celebrations to the Republican response. This will be supported by an explanation of the two events that triggered the start of the mural painting for both factions: the Battle of the Boyne for the Loyalists and the 1981 hunger strike for the Republicans. In the third and last chapter of this dissertation, a key of the main themes, symbols, acronyms and dominant colours which can be found in Loyalist and Republican murals is provided. Furthermore, one mural for each faction is looked at more closely, with an analysis of the symbols which are present in it.

High numbers of DC-SIGN+ dendritic cells in lesional skin of cutaneous T-cell lymphoma

The role of dendritic cells (DCs) in disease progression of primary cutaneous T-cell lymphoma (CTCL) is not well understood. With their unique ability to induce primary immune responses as well as immunotolerance, DCs play a critical role in mediation of anti-tumor immune responses. Tumor-infiltrating DCs have been determined to represent important prognostic factors in a variety of human tumors.

Skin cancers in renal transplant recipients: A description of the renal transplant cohort in Bern

BACKGROUND/AIMS: Skin tumours, in particular squamous-cell carcinomas (SCC), are the most common malignant conditions developing in transplant recipients. The aim of this study is to investigate the frequency and type of skin cancer in patients receiving immunosuppressive therapy after organ transplantation. METHODS: Multivariate logistic regression analysis was performed on data of 243 renal transplant patients who attended the dermatology outpatient clinic for the first time after transplantation in the period January 2002-October 2005. RESULTS: We found an increased risk of actinic keratosis (AK) and SCC in renal transplant recipients with a basal cell carcinoma (BCC) / SCC ratio of 1:7. Older patients had AK more frequently (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.06-1.15; p <0.0001) and SCC (OR 1.14, CI 1.07-1.22; p <0.0001) than younger patients. Men had AK (OR 0.19, CI 0.08-0.45; p = 0.0002) and SCC (OR 0.25, CI 0.07-0.89; p = 0.0332) more frequently than women. The duration of immunosuppressive therapy correlated significantly with the numbers of AKs (OR 1.15, CI 1.08-1.24; p <0.0001) and SCCs (OR 1.16, CI 1.05-1.28; p = 0.0025), and patients with fair skin had more AKs (OR 0.31, CI 0.14-1.24; p <0.0001) and SCCs (OR 0.11, CI 0.02-0.52; p = 0.0054) than darker skinned patients. We could not identify any specific immunosuppressive drug as a distinct risk factor for AK or non-melanoma skin cancer (NMSC). CONCLUSION: Skin cancers are increased in the renal transplant population. Main risk factors for skin cancers are fair skin type and long duration of immunosuppressive therapy. A follow-up programme is necessary for early detection of skin cancer and precancerous conditions. Preventive strategies should include specialist dermatological monitoring and self-examination.

Internet based health promotion campaign against skin cancer - Results of www.skincheck.ch in Switzerland

Conventional skin cancer prevention programs appeal to limited populations, and the middle aged male population responds less frequently. Our objective was to establish a complementary health promotion campaign tool for skin cancer prevention. Internet-based education, instruction for self assessment and teledermatological evaluation of skin lesions by an expert commission of dermatologists was used. Compliance and clinical diagnosis was assessed in a subgroup. 12,000 users visited the educational website. There was strong interest among the middle aged male population (53% (N = 262): male; mean age: 42). 28.5% of examined lesions (N = 494) were considered suspicious. Email requests, sent to the group whose lesions where considered suspicious, were answered by 46.0% of females (N = 29) and 59.7% of males (N = 46) with a female distribution predominantly in younger ages (52.6% of females with known age: < 30 years). Males were predominantly represented over 30 years (86.2% of all males). According to user's declarations, at least 8 (8.5%) malignant lesions (1 melanoma in situ, 1 squamous cell carcinoma, 4 basal cell carcinomas, 2 malignant lesions without declared diagnosis) were finally diagnosed by physicians. We conclude that internet-based, interactive, educational programs, in addition to existing health promotion campaigns, can enhance public participation in the middle aged male population in skin cancer prevention.
