From organized internal traffic to collective navigation of bacterial swarms

International Nuclear Information System (INIS)

Ariel, Gil; Shklarsh, Adi; Kalisman, Oren; Ben-Jacob, Eshel; Ingham, Colin

2013-01-01

Bacterial swarming resulting in collective navigation over surfaces provides a valuable example of cooperative colonization of new territories. The social bacterium Paenibacillus vortex exhibits successful and diverse swarming strategies. When grown on hard agar surfaces with peptone, P. vortex develops complex colonies of vortices (rotating bacterial aggregates). In contrast, during growth on Mueller–Hinton broth gelled into a soft agar surface, a new strategy of multi-level organization is revealed: the colonies are organized into a special network of swarms (or ‘snakes’ of a fraction of millimeter in width) with intricate internal traffic. More specifically, cell movement is organized in two or three lanes of bacteria traveling between the back and the front of the swarm. This special form of cellular logistics suggests new methods in which bacteria can share resources and risk while searching for food or migrating into new territories. While the vortices-based organization on hard agar surfaces has been modeled before, here, we introduce a new multi-agent bacterial swarming model devised to capture the swarms-based organization on soft surfaces. We test two putative generic mechanisms that may underlie the observed swarming logistics: (i) chemo-activated taxis in response to chemical cues and (ii) special align-and-push interactions between the bacteria and the boundary of the layer of lubricant collectively generated by the swarming bacteria. Using realistic parameters, the model captures the observed phenomena with semi-quantitative agreement in terms of the velocity as well as the dynamics of the swarm and its envelope. This agreement implies that the bacteria interactions with the swarm boundary play a crucial role in mediating the interplay between the collective movement of the swarm and the internal traffic dynamics.

EFTHALIA CHATZIGIANNI

2006-01-01

Full Text Available The purpose of this article is to demonstrate the role of the International Olympic Committee as an International Organization in the field of interdependent world politics. Contemporary international community is organized on the basis of international organizations that contribute to the cooperation and understanding of the people especially in areas that enjoy human recognition worldwide. These organizations may function as agents of world solidarity and aim directly or indirectly at the promotion of understanding between people and consequently at the establishment of peace. They also carry out activities that aim at influencing national and international politics relevant to their respective goals. In this field, the IOC, as the most important International Non-Governmental Organization in the field of sport, plays a significant role. With an activity spanning more than a century, the IOC has been able to unify nations under the notion of Olympic ideals. This article aims at contributing partly to the theoretical discussion concerning the ability of the IOC to act as an International Non Governmental Organization and fit in the pieces of world governance in terms of structure and activities. More specifically, it examines this ability in relation to the following facts: a the IOC enjoys international recognition and has a well-established international network, b it has a dynamic character and c it has the authority and financial capacity to function on international and national level as the representative of its 202 members, the National Olympic Committees (NOCs.

Influence of Moraxella sp. colonization on the kidney proteome of farmed gilthead sea breams (Sparus aurata, L.

2010-10-01

Full Text Available Abstract Background Currently, presence of Moraxella sp. in internal organs of fish is not considered detrimental for fish farming. However, bacterial colonization of internal organs can affect fish wellness and decrease growth rate, stress resistance, and immune response. Recently, there have been reports by farmers concerning slow growth, poor feed conversion, and low average weight increase of fish farmed in offshore floating sea cages, often associated with internal organ colonization by Moraxella sp. Therefore, presence of these opportunistic bacteria deserves further investigations for elucidating incidence and impact on fish metabolism. Results A total of 960 gilthead sea breams (Sparus aurata, L., collected along 17 months from four offshore sea cage plants and two natural lagoons in Sardinia, were subjected to routine microbiological examination of internal organs throughout the production cycle. Thirteen subjects (1.35% were found positive for Moraxella sp. in the kidney (7, brain (3, eye (1, spleen (1, and perivisceral fat (1. In order to investigate the influence of Moraxella sp. colonization, positive and negative kidney samples were subjected to a differential proteomics study by means of 2-D PAGE and mass spectrometry. Interestingly, Moraxella sp. infected kidneys displayed a concerted upregulation of several mitochondrial enzymes compared to negative tissues, reinforcing previous observations following lipopolysaccharide (LPS challenge in fish. Conclusions Presence of Moraxella sp. in farmed sea bream kidney is able to induce proteome alterations similar to those described following LPS challenge in other fish species. This study revealed that Moraxella sp. might be causing metabolic alterations in fish, and provided indications on proteins that could be investigated as markers of infection by Gram-negative bacteria within farming plants.

[Organization of colon-rectal cancer screening in the Provincial Health Agency of Ragusa].

Science.gov (United States)

Blangiardi, F; Ferrera, G; Cilia, S; Aprile, E

2012-01-01

Cancer screening is a secondary prevention program that permits early diagnosis of neoplasias and precancerous lesions are in order to diminish mortality and morbidity for certain types of tumors (breast, colon-rectal, and cervical). In 2010, the Ragusa Provincial Health Agency began screening for colon-rectal cancer in an experimental phase that initially involved only the municipality of Ragusa but that was then extended to other municipalities of the province. Although the organizing model suffered from many managerial problems including lack of human resources and tools, there was good collaboration and involvement of the public health/hygiene offices and the general practitioners and volunteer associations. This type of networking was useful in that adhesion to screening was well above that expected. Another winning aspect of the project resulted in clear and pertinent communication to the population.

International organizations and their exercise of sovereign powers

CERN Document Server

Sarooshi, Dan

2005-01-01

This book considers the exercise of sovereign powers by international organizations that include the United Nations, the World Trade Organization, and the European Union in order to answer fundamental questions about the relationship between an international organization and its member states. In their membership of international organizations, states must confer some of their sovereign powers upon those organizations. This book develops a three-tiered typology of conferrals which ranges from agency relationships, to delegations of authority, to full transfers of power. The legal aspects of these conferrals are examined, and their implications for the growing importance of international organizations in international relations are assessed.

International organizations and migrant health in Europe.

Science.gov (United States)

Kentikelenis, Alexander E; Shriwise, Amanda

International organizations have defined and managed different aspects of migrant health issues for decades, yet we lack a systematic understanding of how they reach decisions and what they do on the ground. The present article seeks to clarify the state of knowledge on the relationship between international organizations and migrant health in Europe. To do so, we review the operations of six organizations widely recognized as key actors in the field of migrant health: the European Commission, the Regional Office for Europe of the World Health Organization, the International Organization on Migration, Médecins du Monde, Médecins Sans Frontières, and the Open Society Foundation. We find that international organizations operate in a complementary fashion, with each taking on a unique role in migrant health provision. States often rely on international organizations as policy advisors or sub-contractors for interventions, especially in the case of emergencies. These linkages yield a complex web of relationships, which can vary depending on the country under consideration or the health policy issue in question.

Immunological comparison of ovarian and colonic CEA

International Nuclear Information System (INIS)

Burtin, P.; Gendron, M.C.; Maunoury, M.T.; Lamerz, R.; Schnabel, G.

1982-01-01

Ovarian and colonic CEA were compared immunologically by means of antisera prepared against each of them. CEAs of both origins were found identical by immunodiffusion methods. In radioimmunological experiments, slight differences were observed between some but not all ovarian CEAs and colonic CEAs and also between different preparations of colonic CEA: no organ specificity of ovarian CEA could be demonstrated. Finally, CEA level was measured in 41 sera of patients with ovarian carcinoma by two radioimmunoassays, one using colonic CEA as tracer and standard and anti-colonic CEA serum, the other using ovarian CEA and anti-ovarian CEA serum: the values given by the two assays were highly correlated (rsub(s) = 0.8107), meaning that an organ specific assay for ovarian CEA is not needed.

The historical perspectives of the international organizations' role concerning the development and spreading of the peaceful uses of nuclear energy, taking into account the national interests within and towards these organizations, are portrayed. The difference in political status between the so-called nuclear and non-nuclear States, lodged in Articles I and II of the Non-Proliferation Treaty is an important factor. The effects so far of these differences in status on the interest of nuclear States to participate in organizations and on factors which might possibly lead to conflict between these two groups are presented.

Development Internal Problems of Shanghay Cooperation Organization

Directory of Open Access Journals (Sweden)

Oksana Y. Kolegova

2015-01-01

Full Text Available The article analyzes the main internal problems of the Shanghai Cooperation Organization. Particular attention is paid to the conflict of interests of the participating countries, as well as identifying obstacles to strengthen the organization and increase its influence in the international arena. The international organizations are created by the states to meet mutual problems in the course of interstate relations requiring regular cooperation mechanism. Given the background of the Organization, it is important to emphasize that the main reason for the establishment of the Shanghai organization was the need for the united front against the strengthening of the region at the turn of centuries against dangerous trends of terrorism, extremism, separatism, the growth of organized crime. Despite the conflict of interests and the internal and external development challenges thirteen-year history of evolution of the SCO, to some extent proves its effectiveness, moreover, there are the preconditions for its consistent transition to a more comprehensive organization.

Tirosh, Amit; Shimon, Ilan

2017-02-01

In acromegaly the long-term exposure to high growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels may result in specific complications in different human organs, including the thyroid gland and the colon. We will review here the evidence available regarding the characteristic thyroid and colon complications in acromegaly. This review summarizes the published data observing noncancerous structural abnormalities (thyroid nodules, colonic polyps) and thyroid and colon cancer in patients diagnosed with acromegaly. Thyroid micro-carcinomas are probably over-diagnosed among acromegalic patients. In regard to colon cancer, there is no sufficient data to suggest that colon cancer risk is higher in acromegaly compared to the general population.

Greer, Lauren T; Gillern, Suzanne M; Vertrees, Amy E

2013-02-01

The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

International Organizations and Trade

The three central primitives of international trade theory are consumer preferences, factor endowments, and the production technologies that allow firms to transform factors of production into consumer goods. A limitation of traditional trade theory, however, is that the specification of technology treats the mapping between factors of production and final goods as a black box. In practice, the decisions of agents in organizations determine this mapping. Recently, international trade economis...

TRANSNATIONAL ORGANIZED CRIME. AN (INTERNATIONAL SECURITY PERSPECTIVE

Directory of Open Access Journals (Sweden)

Ionel Stoica

2016-10-01

Full Text Available For the past two decades organized crime has become a transnational phenomenon, and its impact is still far from being fully known and understood by common people. Its forms of manifestation, whether explicit, or subtle, are permanently evolving and adapting. As a result, its interference with the activities from the legal area makes it difficult to identify and counteract. After a long period of time when it was more a peripheral phenomenon, current transnational organized crime tends to become a major danger to the political, social and economic stability of the states. Through its nature and goals, as well as through the complexity of its forms of manifestation, transnational organized crime represents a major challenge for the state and nonstate organizations that deal with national and international security This paper focuses on the phenomenon starting from some of the most influent theories in international relations, presents the current features of transnational organized criminal groups and analyzes the causes and the favoring factors of the phenomenon, as well as the impact of the phenomenon upon national and international security at political, economic-financial and military level. The approach is an interdisciplinary one and also covers the nexus between transnational organized crime and international terrorism.

To present the epidemiology of the outbreak and the description of patients with infection or colonization of the respiratory tract caused by A. baumannii in an Internal Medicine ward. 20 consecutively patients hospitalized in the Internal Medicine ward were studied during 18 months with isolation of multiresistant A. baumanni in respiratory tract specimens with or without clinical signs of infection. Starting on an index case, that was a patient coming from other hospital with diagnosis of nosocomial Acinetobacter pneumonia, we detected 20 patients. The age of the patients ranged from 48 to 95 years, with a mean of 71.4 years. Eighty percent were males. The clinical features were similar: advanced age, with chronic diseases (35 percent diabetics, 45 percent with chronic lung diseases), and use of broad-spectrum antibiotics agents, fundamentally third generation cephalosporin (70 percent), clarithromycin (55 percent) and quinolones (30 percent). 75 percent of patients were in the same ward. Eight (40 percent) of the patients with chronic lung diseases were subjects with COPD, two with asthma and chronic glucocorticoids treatment, and one with a sleep apnea. In four cases the isolation was considered a colonization. The mean stay was 26.15 days, and the mortality 40 percent. The nosocomial infection caused by Acinetobacter baumannii is responsible of a high morbi-mortality between the patients hospitalized in an Internal Medicine ward, and produce an increase in length of stay. It is necessary a combination of control measures to prevent the transmission in the hospital and the outbreak of new multiresistant strains.

In particular, we contend that in order to explain change in international organizations (IOs) we cannot simply dichotomize between change and the lack thereof. Rather, change is best conceptualized as made up of two...... in the field helps to account for the speed of change (slow vs. rapid), whereas the openness of the organization to the inputs coming from the field helps to explain the scope of change (incremental vs. radical). We illustrate our argument by comparing the changes in the International Monetary Fund's policies...... dimensions: speed and scope. The combination of the two dimensions leads to a taxonomy with four distinct types of policy change.

Antimicrobial-resistant Gram-negative infections are a significant cause of mortality in young infants. We aimed to determine characteristics of, and risk factors for, colonization and invasive infection caused by 3rd generation cephalosporin (3GC) or carbapenem-resistant organisms in outborn infants admitted to a neonatal unit (NU) in Cambodia. During the first year of operation, patients admitted to the Angkor Hospital for Children NU, Siem Reap, Cambodia, underwent rectal swabbing on admission and twice weekly until discharge. Swabs were taken also from 7 environmental sites. Swabs were cultured to identify 3GC or carbapenem-resistant Acinetobacter sp., Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. The study included 333 infants with a median age at NU admission of 10 days (range, 0-43). Colonization by ≥1 3GC-resistant organism was detected in 85.9% (286/333). Admission swabs were collected in 289 infants: 61.9% were colonized by a 3GC-resistant organism at the time of admission, and a further 23.2% were colonized during hospitalization, at a median of 4 days [95% confidence interval: 3-5]. Probiotic treatment (hazard ratio: 0.58; 95% confidence interval: 0.35-0.98) was associated with delayed colonization. Colonization by a carbapenem-resistant organism occurred in 25 (7.5%) infants. Six infants had NU-associated K. pneumoniae bacteremia; phenotypically identical colonizing strains were found in 3 infants. Environmental colonization occurred early. Colonization by antimicrobial-resistant Gram-negative organisms occurred early in hospitalized Cambodian infants and was associated with subsequent invasive infection. Trials of potential interventions such as probiotics are needed.

Microbial colonization and degradation of polyethylene and biodegradable plastic bags in temperate fine-grained organic-rich marine sediments.

To date, the longevity of plastic litter at the sea floor is poorly constrained. The present study compares colonization and biodegradation of plastic bags by aerobic and anaerobic benthic microbes in temperate fine-grained organic-rich marine sediments. Samples of polyethylene and biodegradable plastic carrier bags were incubated in natural oxic and anoxic sediments from Eckernförde Bay (Western Baltic Sea) for 98 days. Analyses included (1) microbial colonization rates on the bags, (2) examination of the surface structure, wettability, and chemistry, and (3) mass loss of the samples during incubation. On average, biodegradable plastic bags were colonized five times higher by aerobic and eight times higher by anaerobic microbes than polyethylene bags. Both types of bags showed no sign of biodegradation during this study. Therefore, marine sediment in temperate coastal zones may represent a long-term sink for plastic litter and also supposedly compostable material. Copyright © 2016 Elsevier Ltd. All rights reserved.

Cancers in the proximal colon, distal colon, and rectum are frequently studied together; however, there are biological differences in cancers across these sites, particularly in the prevalence of microsatellite instability. We assessed the differences in survival by colon or rectal cancer site, considering the contribution of microsatellite instability to such differences. This is a population-based prospective cohort study for cancer survival. This study was conducted within the Colon Cancer Family Registry, an international consortium. Participants were identified from population-based cancer registries in the United States, Canada, and Australia. Information on tumor site, microsatellite instability, and survival after diagnosis was available for 3284 men and women diagnosed with incident invasive colon or rectal cancer between 1997 and 2002, with ages at diagnosis ranging from 18 to 74. Cox regression was used to calculate hazard ratios for the association between all-cause mortality and tumor location, overall and by microsatellite instability status. Distal colon (HR, 0.59; 95% CI, 0.49-0.71) and rectal cancers (HR, 0.68; 95% CI, 0.57-0.81) were associated with lower mortality than proximal colon cancer overall. Compared specifically with patients with proximal colon cancer exhibiting no/low microsatellite instability, patients with distal colon and rectal cancers experienced lower mortality, regardless of microsatellite instability status; patients with proximal colon cancer exhibiting high microsatellite instability had the lowest mortality. Study limitations include the absence of stage at diagnosis and cause-of-death information for all but a subset of study participants. Some patient groups defined jointly by tumor site and microsatellite instability status are subject to small numbers. Proximal colon cancer survival differs from survival for distal colon and rectal cancer in a manner apparently dependent on microsatellite instability status. These

In this paper, the implicit and explicit conceptualizations of international organizations found in the three major theories of international relations are outlined and compared. It turns out that in a neorealist framework, international organizations can be explained; however, they exhibit no autonomy and cannot therefore be conceptualized as a corporate actor. Principally, the same applies to rational choice institutionalism, although limited autonomy is conceivable. Both theories are reduc...

Molecular Basis of Alcohol-Related Gastric and Colon Cancer.

Science.gov (United States)

Na, Hye-Kyung; Lee, Ja Young

2017-05-24

Many meta-analysis, large cohort studies, and experimental studies suggest that chronic alcohol consumption increases the risk of gastric and colon cancer. Ethanol is metabolized by alcohol dehydrogenases (ADH), catalase or cytochrome P450 2E1 (CYP2E1) to acetaldehyde, which is then further oxidized to acetate by aldehyde dehydrogenase (ALDH). Acetaldehyde has been classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen to humans. The acetaldehyde level in the stomach and colon is locally influenced by gastric colonization by Helicobacter pylori or colonic microbes, as well as polymorphisms in the genes encoding tissue alcohol metabolizing enzymes, especially ALDH2. Alcohol stimulates the uptake of carcinogens and their metabolism and also changes the composition of enteric microbes in a way to enhance the aldehyde level. Alcohol also undergoes chemical coupling to membrane phospholipids and disrupts organization of tight junctions, leading to nuclear translocation of β-catenin and ZONAB, which may contributes to regulation of genes involved in proliferation, invasion and metastasis. Alcohol also generates reactive oxygen species (ROS) by suppressing the expression of antioxidant and cytoprotective enzymes and inducing expression of CYP2E1 which contribute to the metabolic activation of chemical carcinogens. Besides exerting genotoxic effects by directly damaging DNA, ROS can activates signaling molecules involved in inflammation, metastasis and angiogenesis. In addition, alcohol consumption induces folate deficiency, which may result in aberrant DNA methylation profiles, thereby influencing cancer-related gene expression.

Purpose: To identify organs at risk (OAR) and analyze the dose volume histograms (DVHs) for intracavitary brachytherapy in cancer of the cervix. Late toxicities are our concern in treatment of cancer cervix especially as it is presenting in younger age population. Material and Methods: Patients with cancer of the cervix were treated using CT and MRI compatible, high dose rate, (HDR) applicators. CT images were acquired with the intra-uterine tube and colpostats in place and subsequently imported into Varian Brachyvision planning software. We identified the gross tumour volume (GTV) and organs at risk (OARs) and analyzed the dose distribution using dose volume histograms (DVHs). Doses were calculated according to ICRU 38. Critical tissue DVHs were analysed following the American Brachytherapy Society rules. Dose points are recorded as the dose encompassed by the greatest contiguous I cm3, 2 cm3, and 5 cm3 volumes in the plan. Results: We found the sigmoid colon to be a relatively immobile structure that repeatedly received doses in excess of 70% of the intended point A dose. The only solution in order to bring sigmoid DVHs within 5% toxicity limits was to reduce the dose to point A. Planning images and DVHs for the OARs are shown as an example of our work. Conclusion: The recto-sigmoid colon is identified as an unexpected OAR in a majority of cervix brachytherapy plans. A new consensus on the DVH limit of this structure will be needed in the era of CT planned brachytherapy, if arbitrary dose reductions to point A are to be the solution to the problem of sigmoid DVHs that exceed conventional tolerance limits

Development and function of secondary and tertiary lymphoid organs in the small intestine and the colon

Full Text Available The immune system of the gut has evolved a number of specific lymphoid structures that contribute to homeostasis in the face of microbial colonization and food-derived antigenic challenge. These lymphoid organs encompass Peyer’s patches (PP in the small intestine and their colonic counterparts that develop in a programmed fashion before birth. In addition, the gut harbors a network of lymphoid tissues that is commonly designated as solitary intestinal lymphoid tissues (SILT. In contrast to PP, SILT develop strictly after birth and consist of a dynamic continuum of structures ranging from small cryptopatches (CP to large, mature isolated lymphoid follicles (ILF. Although the development of PP and SILT follow similar principles, such as an early clustering of lymphoid tissue inducer (LTi cells and the requirement for lymphotoxin beta (LTβ receptor-mediated signaling, the formation of CP and their further maturation into ILF is associated with additional intrinsic and environmental signals. Moreover, recent data also indicate that specific differences exist in the regulation of ILF formation between the small intestine and the colon. Importantly, intestinal inflammation in both mice and humans is associated with a strong expansion of the lymphoid network in the gut. Recent experiments in mice suggest that these structures, although they resemble large, mature ILF in appearance, may represent de novo-induced tertiary lymphoid organs (TLO. While so far it is not clear whether intestinal TLO contribute to the exacerbation of inflammatory pathology, it has been shown that ILF provide the critical microenvironment necessary for the induction of an effective host response upon infection with enteric bacterial pathogens. Regarding the importance of ILF for intestinal immunity, interfering with the development and maturation of these lymphoid tissues may offer novel means for manipulating the immune response during intestinal infection or inflammation.

A Transient Exposure to Symbiosis-Competent Bacteria Induces Light Organ Morphogenesis in the Host Squid.

Doino, J A; McFall-Ngai, M J

1995-12-01

Recent studies of the symbiotic association between the Hawaiian sepiolid squid Euprymna scolopes and the luminous bacterium Vibrio fischeri have shown that colonization of juvenile squid with symbiosis-competent bacteria induces morphogenetic changes of the light organ. These changes occur over a 4-day period and include cell death and tissue regression of the external ciliated epithelium. In the absence of bacterial colonization, morphogenesis does not occur. To determine whether the bacteria must be present throughout the morphogenetic process, we used the antibiotic chloramphenicol to clear the light organ of bacteria at various times during the initial colonization. We provide evidence in this study that a transient, 12-hour exposure to symbiosis-competent bacteria is necessary and sufficient to induce tissue regression in the light organ over the next several days. Further, we show that successful entrance into the light organ is necessary to induce morphogenesis, suggesting that induction results from bacterial interaction with internal crypt cells and not with the external ciliated epithelium. Finally, no difference in development was observed when the light organ was colonized by a mutant strain of V. fischeri that did not produce autoinducer, a potential light organ morphogen.

Chaloner, A; Rao, A; Al-Chaer, E D; Greenwood-Van Meerveld, B

2010-02-01

Previous studies have shown that early life trauma induced by maternal separation or colonic irritation leads to hypersensitivity to colorectal distension in adulthood. We tested the hypothesis that repetitive colorectal distension in neonates leads to abnormalities in colonic permeability and smooth muscle function in the adult rat. In neonatal rats, repetitive colorectal distension was performed on days 8, 10, and 12. As adults, stool consistency was graded from 0 (formed stool) to 3 (liquid stool). Colonic tissue was isolated for histology and myeloperoxidase levels. The colonic mucosa was placed in modified Ussing chambers for measurements of permeability and short-circuit current responses to forskolin, electrical field stimulation, and carbachol. Segments of colonic musculature were placed in organ baths and contractile response to potassium chloride, electrical field stimulation, and carbachol were determined. In adult rats that experienced neonatal colonic irritation, no significant changes in colonic histology or myeloperoxidase activity were observed; however, stool consistency scores were increased. Mucosal permeability, measured as an increase in basal conductance, was significantly increased but no changes in short-circuit current responses were observed. In adulthood, rats that underwent colorectal distension as neonates exhibited an elevated smooth muscle contractile response to potassium chloride, but no changes in response to electrical field stimulation or carbachol. In summary, neonatal colonic irritation, shown previously to produce colonic hypersensitivity, leads to significant alterations in colonic mucosal and smooth muscle function characterized by loose stools, increased mucosal permeability, and increased smooth muscle contractility in the absence of colon inflammation in adulthood.

2015-01-01

International Organizations as Orchestrators reveals how IOs leverage their limited authority and resources to increase their effectiveness, power, and autonomy from states. By 'orchestrating' intermediaries - including NGOs - IOs can shape and steer global governance without engaging in hard, direct regulation. This volume is organized around a theoretical model that emphasizes voluntary collaboration and support. An outstanding group of scholars investigate the significance of orchestration across key issue areas, including trade, finance, environment and labor, and in leading organizations, including the GEF, G20, WTO, EU, Kimberley Process, UNEP and ILO. The empirical studies find that orchestration is pervasive. They broadly confirm the theoretical hypotheses while providing important new insights, especially that states often welcome IO orchestration as achieving governance without creating strong institutions. This volume changes our understanding of the relationships among IOs, nonstate actors and sta...

The health threat posed by radionuclides has stimulated increased efforts to developed characterization on the biological behavior of radionuclides in humans in all ages. In an effort motivated largely by the Chernobyl nuclear accident, the International Commission on Radiological Protection (ICRP) is assembling a set of age specific biokinetic models for environmentally important radioelements. Radioactive substances in the air, mainly through the respiratory system and digestive tract, is inside the body. Radioactive substances are unevenly distributed in various organs and tissues. Therefore, the degree of damage will depend not only on the dose of radiation have but also on the critical organ, which is the most accumulation of radioactive substances, which leads to the defeat of the entire human body. The main objective of radiation protection, to avoid exceeding the maximum permissible doses of external and internal exposure of a person to prevent the physical and genetic damage people. The maximum tolerated dose (MTD) of radiation is called a dose of radiation a person in uniform getting her for 50 years does not cause changes in the health of the exposed individual and his progeny. The following classification of critical organs, depending on the category of exposure on their degree of sensitivity to radiation: First group: the whole body, gonads and red bone marrow; Second group: muscle, fat, liver, kidney, spleen, gastrointestinal tract, lungs and lens of the eye; The third group: bone, thyroid and skin; Fourth group: the hands, forearms, feet. MTD exposure whole body, gonads and bone marrow represent the maximum exposures (5 rem per year) experienced by people in their normal activities. The purpose of this article is intended dose received from various internal organs of the radionuclides that may enter the body by inhalation, and gastrointestinal tract. The biokinetic model describes the time dependent distribution and excretion of different

Full Text Available The incidence rate of infection by multidrug-resistant organisms (MDROs can affect the accuracy of etiological diagnosis when using American Thoracic Society (ATS guidelines. We determined the accuracy of the ATS guidelines in predicting infection or colonization by MDROs over 18 months at a single ICU in eastern China.This prospective observational study examined consecutive patients who were admitted to an intensive care unit (ICU in Nanjing, China. MDROs were defined as bacteria that were resistant to at least three antimicrobial classes, such as methicillin-resistant Staphylococcus aureus (MRSA, vancomycin-resistant enterococci (VRE, Pseudomonas aeruginosa, Acinetobacter baumannii. Screening for MDROs was performed at ICU admission and discharge. Risk factors for infection or colonization with MDROs were recorded, and the accuracy of the ATS guidelines in predicting infection or colonization with MDROs was documented.There were 610 patients, 225 (37% of whom were colonized or infected with MDROs at ICU admission, and this increased to 311 (51% at discharge. At admission, the sensitivity (70.0%, specificity (31.6%, positive predictive value (38.2%, and negative predictive value (63.5%, all based on ATS guidelines for infection or colonization with MDROs were low. The negative predictive value was greater in patients from departments with MDRO infection rates of 31-40% than in patients from departments with MDRO infection rates of 30% or less and from departments with MDRO infection rates more than 40%.ATS criteria were not reliable in predicting infection or colonization with MDROs in our ICU. The negative predictive value was greater in patients from departments with intermediate rates of MDRO infection than in patients from departments with low or high rates of MDRO infection.ClinicalTrials.gov NCT01667991.

Copepod colonization of organic and inorganic substrata at a deep-sea hydrothermal vent site on the Mid-Atlantic Ridge

The few existing studies on deep-sea hydrothermal vent copepods indicate low connectivity with surrounding environments and reveal high endemism among vents. However, the finding of non-endemic copepod species in association with engineer species at different reduced ecosystems poses questions about the dispersal of copepods and the colonization of hydrothermal vents as well as their ecological connectivity. The objective of this study is to understand copepod colonization patterns at a hydrothermal vent site in response to environmental factors such as temperature and fluid flow as well as the presence of different types of substrata. To address this objective, an in situ experiment was deployed using both organic (woods, pig bones) and inorganic (slates) substrata along a gradient of hydrothermal activity at the Lucky Strike vent field (Eiffel Tower, Mid-Atlantic Ridge). The substrata were deployed in 2011 during the MoMARSAT cruise and were recovered after two years in 2013. Overall, copepod density showed significant differences between substrata types, but was similar among different hydrothermal activity regimes. Highest densities were observed on woods at sites with moderate or low fluid input, whereas bones were the most densely colonized substrata at the 2 sites with higher hydrothermal influence. Although differences in copepod diversity were not significant, the observed trends revealed overall increasing diversity with decreasing temperature and fluid input. Slates showed highest diversity compared to the organic substrata. Temperature and fluid input had a significant influence on copepod community composition, resulting in higher similarity among stations with relatively high and low fluid inputs, respectively. While vent-specialists such as dirivultids and the tegastid Smacigastes micheli dominated substrata at high vent activity, the experiment demonstrated increasing abundance and dominance of non-vent taxa with decreasing temperature and fluid

Colon in acute intestinal infection.

Science.gov (United States)

Guarino, Alfredo; Buccigrossi, Vittoria; Armellino, Carla

2009-04-01

The colon is actively implicated in intestinal infections not only as a target of enteric pathogens and their products but also as a target organ for treatment. In the presence of diarrhea, both of osmotic and secretory nature, the colon reacts with homeostatic mechanisms to increase ion absorption. These mechanisms can be effectively exploited to decrease fluid discharge. A model of intestinal infections using rotavirus (RV) in colonic cells was set up and used to define a dual model of secretory and osmotic diarrhea in sequence. Using this model, antidiarrheal drugs were tested, namely zinc and the enkephalinase inhibitor racecadotril. Zinc was able to decrease the enterotoxic activity responsible for secretory diarrhea. It also inhibited the cytotoxic effect of RV. The mechanism of zinc was related at least in part to the activation of MAPK activity, but also a direct antiviral effect was observed. Racecadotril showed a potent and selective inhibition of active secretion, being particularly effective in the first phase of RV diarrhea. The use of drugs active at the colonic level, therefore, offers effective options to treat intestinal infections in childhood. In addition, the colon is the natural site of colonic microflora, a target of probiotic therapy, which is the first line of approach recommended by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition to treat infectious diarrhea.

Vibrio cholerae Colonization of Soft-Shelled Turtles.

Vibrio cholerae is an important human pathogen and environmental microflora species that can both propagate in the human intestine and proliferate in zooplankton and aquatic organisms. Cholera is transmitted through food and water. In recent years, outbreaks caused by V. cholerae -contaminated soft-shelled turtles, contaminated mainly with toxigenic serogroup O139, have been frequently reported, posing a new foodborne disease public health problem. In this study, the colonization by toxigenic V. cholerae on the body surfaces and intestines of soft-shelled turtles was explored. Preferred colonization sites on the turtle body surfaces, mainly the carapace and calipash of the dorsal side, were observed for the O139 and O1 strains. Intestinal colonization was also found. The colonization factors of V. cholerae played different roles in the colonization of the soft-shelled turtle's body surface and intestine. Mannose-sensitive hemagglutinin (MSHA) of V. cholerae was necessary for body surface colonization, but no roles were found for toxin-coregulated pili (TCP) or N -acetylglucosamine-binding protein A (GBPA). Both TCP and GBPA play important roles for colonization in the intestine, whereas the deletion of MSHA revealed only a minor colonization-promoting role for this factor. Our study demonstrated that V. cholerae can colonize the surfaces and the intestines of soft-shelled turtles and indicated that the soft-shelled turtles played a role in the transmission of cholera. In addition, this study showed that the soft-shelled turtle has potential value as an animal model in studies of the colonization and environmental adaption mechanisms of V. cholerae in aquatic organisms. IMPORTANCE Cholera is transmitted through water and food. Soft-shelled turtles contaminated with Vibrio cholerae (commonly the serogroup O139 strains) have caused many foodborne infections and outbreaks in recent years, and they have become a foodborne disease problem.

We have begun to colonize space, even to the extent of early space tourism. Our early Vostok, Mercury, Gemini, Apollo, Skylab, Spacehab, Mir and now ISS are humankind's first ventures toward colonization. Efforts are underway to provide short space tours, and endeavors such as the X-Prize are encouraging entrepreneurs to provide new systems. Many believe that extended space travel (colonization) will do for the 21st century what aviation did for the 20th. Our current concerns including terrorism, hunger, disease, and problems of air quality, safe abundant water, poverty, and weather vagaries tend to overshadow long-term activities such as Space Colonization in the minds of many. Our leading ``think tanks'' such as the Woodrow Wilson International Center for Scholars and the Brookings Institute do not rate space travel high on lists of future beneficial undertakings even though many of the concerns listed above are prominently featured. It is the contention of this paper that Space Colonization will lead toward solutions to many of the emerging problems of our Earth, both technological and sociological. The breadth of the enterprise far exceeds the scope of our normal single-purpose missions and, therefore, its benefits will be greater.

Endophytic colonization of plant roots by nitrogen-fixing bacteria

International Nuclear Information System (INIS)

Cocking, Edward C.

2001-01-01

Nitrogen-fixing bacteria are able to enter into roots from the rhizosphere, particularly at the base of emerging lateral roots, between epidermal cells and through root hairs. In the rhizosphere growing root hairs play an important role in symbiotic recognition in legume crops. Nodulated legumes in endosymbiosis with rhizobia are amongst the most prominent nitrogen-fixing systems in agriculture. The inoculation of non-legumes, especially cereals, with various non-rhizobial diazotrophic bacteria has been undertaken with the expectation that they would establish themselves intercellularly within the root system, fixing nitrogen endophytic ally and providing combined nitrogen for enhanced crop production. However, in most instances bacteria colonize only the surface of the roots and remain vulnerable to competition from other rhizosphere micro-organisms, even when the nitrogen-fixing bacteria are endophytic, benefits to the plant may result from better uptake of soil nutrients rather than from endophytic nitrogen fixation. Azorhizobium caulinodans is known to enter the root system of cereals, other nonlegume crops and Arabidopsis, by intercellular invasion between epidermal cells and to internally colonize the plant intercellularly, including the xylem. This raises the possibility that xylem colonization might provide a nonnodular niche for endosymbiotic nitrogen fixation in rice, wheat, maize, sorghum and other non-legume crops. A particularly interesting, naturally occurring, non-qodular xylem colonising endophytic diazotrophic interaction with evidence for endophytic nitrogen fixation is that of Gluconacetobacter diazotrophicus in sugarcane. Could this beneficial endophytic colonization of sugarcane by G. diazotrophicus be extended to other members of the Gramineae, including the major cereals, and to other major non-legume crops of the World?

Hospital staff must engage in a process of continual learning to improve their healthcare skills and provide a superior service to their patients. Internal marketing helps hospital administrators to improve the quality of service provided by nursing staff to their patients and allows hospitals to build a learning culture and enhance the organizational commitment of its nursing staff. Our empirical study provides nursing managers with a tool to allow them to initiate a change in the attitudes of nurses towards work, by constructing a new 'learning organization' and using effective internal marketing. A cross-sectional design was employed. Two hundred questionnaires were distributed to nurses working in either a medical centre or a regional hospital in Taichung City, Taiwan, and 114 valid questionnaires were returned (response rate: 57%). The entire process of distribution and returns was completed between 1 October and 31 October 2009. Hypothesis testing was conducted using structural equation modelling. A significant positive correlation was found between the existence of a 'learning organization', internal marketing, and organizational commitment. Internal marketing was a mediator between creating a learning organization and organizational commitment. Nursing managers may be able to apply the creation of a learning organization to strategies that can strengthen employee organizational commitment. Further, when promoting the creation of a learning organization, managers can coordinate their internal marketing practices to enhance the organizational commitment of nurses.

Aberrant expression of O-glycans is a hallmark of epithelial cancers. Mucin type O-glycosylation is initiated by a large family of UDP-GalNAc:polypeptide N-acetyl-galactosaminyltransferases (GalNAc-Ts), that target different proteins and are differentially expressed in cells and organs. Here we...... investigated the expression patterns of all of the GalNAc-Ts in colon cancer by analysing transcriptomic data. We found that GalNAc-T6 was highly upregulated in colon adenocarcinomas but absent in normal-appearing adjacent colon tissue. The results were verified by immunohistochemistry, suggesting that Gal......NAc-T6 plays a role in colon carcinogenesis. To investigate the function of GalNAc-T6 in colon cancer, we used precise gene targeting to produce isogenic colon cancer cell lines with a knockout/-rescue system for GalNAc-T6. GalNAc-T6 expression was associated with a cancer-like, dysplastic growth pattern...

Intestinal Colonization Dynamics of Vibrio cholerae.

Directory of Open Access Journals (Sweden)

Salvador Almagro-Moreno

2015-05-01

Full Text Available To cause the diarrheal disease cholera, Vibrio cholerae must effectively colonize the small intestine. In order to do so, the bacterium needs to successfully travel through the stomach and withstand the presence of agents such as bile and antimicrobial peptides in the intestinal lumen and mucus. The bacterial cells penetrate the viscous mucus layer covering the epithelium and attach and proliferate on its surface. In this review, we discuss recent developments and known aspects of the early stages of V. cholerae intestinal colonization and highlight areas that remain to be fully understood. We propose mechanisms and postulate a model that covers some of the steps that are required in order for the bacterium to efficiently colonize the human host. A deeper understanding of the colonization dynamics of V. cholerae and other intestinal pathogens will provide us with a variety of novel targets and strategies to avoid the diseases caused by these organisms.

To assess the usefulness of en bloc right hemicolectomy with pancreaticoduodenectomy (RHCPD) for locally advanced right-sided colon cancer (LARCC). We retrospectively reviewed the database of Saitama Medical Center, Jichi Medical University, between January 2009 and December 2016. During this time, 299 patients underwent radical right hemicolectomy for right-sided colon cancer. Among them, 5 underwent RHCPD for LARCC with tumor infiltration to adjacent organs. Preoperative computed tomography (CT) was routinely performed to evaluate local tumor infiltration into adjacent organs. During the operation, we evaluated the resectability and the amount of infiltration into the adjacent organs without dissecting the adherent organs from the cancer. When we confirmed that radical resection was feasible and could lead to R0 resection, we performed RHCPD. The clinical data were carefully reviewed, and the demographic variables, intraoperative data, and postoperative parameters were recorded. The median age of the 5 patients who underwent RHCPD for LARCC was 70 years. The tumors were located in the ascending colon (three patients) and transverse colon (two patients). Preoperative CT revealed infiltration of the tumor into the duodenum in all patients, the pancreas in four patients, the superior mesenteric vein (SMV) in two patients, and tumor thrombosis in the SMV in one patient. We performed RHCPD plus SMV resection in three patients. Major postoperative complications occurred in 3 patients (60%) as pancreatic fistula (grade B and grade C, according to International Study Group on Pancreatic Fistula Definition) and delayed gastric empty. None of the patients died during their hospital stay. A histological examination confirmed malignant infiltration into the duodenum and/or pancreas in 4 patients (80%), and no patients showed any malignant infiltration into the SMV. Two patients were histologically confirmed to have tumor thrombosis in the SMV. All of the tumors had clear

The authors prospectively evaluated 62 patients over 40 years old in whom lymphoid follicles were demonstrated on double-contrast enema examinations. Eighteen patients (29%) had no current radiographic evidence of, or history of, colonic neoplasms. Forty-four patients (71%) had an associated neoplasm. Fourteen patients had associated colonic carcinoma, and ten patients had a history of a previously resected colon cancer. One patient had previously undergone resection for ''polyps.'' Twenty-two patients had an associated ''polyp.'' There were no clinical or radiographic features that could reliably distinguish the neoplastic from the nonneoplastic groups. However, lymphoid follicles in the left colon or diffusely involving the colon were more likely to be associated with a colonic neoplasm. Lymphoid follicles were almost always identified near a malignant lesion

The privileges and immunities of international organizations in domestic courts

2013-01-01

International organizations are increasingly operating across borders and engaging in legal transactions in virtually all jurisdictions. This makes, familiarity with the applicable law and practice imperative for both international organizations and those who engage in legal relations with them. Furthermore, the issue of whether, how, and to what extent domestic courts take into account decisions of foreign and international courts and tribunals in their own decision-making has become increasingly important in recent years. This book provides a comprehensive empirical study of this transnational judicial dialogue, focusing on the law and practice of domestic jurisdictions concerning the legal personality, privileges, and immunities of international organizations. It presents a selection of detailed country-by-country studies, examining the manner of judicial dialogue across domestic jurisdictions, and between national and international courts. The approach taken in this book intersects with three highly topi...

Full Text Available The purpose of the present study was to explore changes in rat colon motility, and determine the roles of calcium and inositol (1,4,5-triphosphate (IP3 in colon dysmotility induced by multiple organ dysfunction syndrome (MODS caused by bacteria peritonitis. The number of stools, the contractility of the muscle strips and the length of smooth muscle cells (SMC in the colon, the concentration of calcium and IP3 in SMC, and serum nitric oxide were measured. Number of stools, fecal weight, IP3 concentration in SMC and serum nitric oxide concentration were 0.77 ± 0.52 pellets, 2.51 ± 0.39 g, 4.14 ± 2.07 pmol/tube, and 113.95 ± 37.89 µmol/L, respectively, for the MODS group (N = 11 vs 1.54 ± 0.64 pellets, 4.32 ± 0.57 g, 8.19 ± 3.11 pmol/tube, and 37.42 ± 19.56 µmol/L for the control group (N = 20; P < 0.05. After treatment with 0.1 mM acetylcholine and 0.1 M potassium chloride, the maximum contraction stress of smooth muscle strips, the length of SMC and the changes of calcium concentration were 593 ± 81 and 458 ± 69 g/cm³, 48.1 ± 11.8 and 69.2 ± 15.7 µM, 250 ± 70 and 167 ± 48%, respectively, for the control group vs 321 ± 53 and 284 ± 56 g/cm³, 65.1 ± 18.5 and 87.2 ± 23.7 µM, 127 ± 35 and 112 ± 35% for the MODS group (P < 0.05. Thus, colon contractility was decreased in MODS, a result possibly related to reduced calcium concentration and IP3 in SMC.

2003-01-01

Objective: To investigate the MR imaging findings of colonic carcinoma and the diagnostic value of MRI. Methods: Multi-planar and multi-sequence MRI scanning, before and after contrast enhancement, were performed in 40 patients with colonic cancer. The patients were fasted for 12 hours, prepared with clean clysis or senna at night before study, given 10 mg of anisodamine 10 minutes before study, and then infused with 800-1000 ml physiological saline immediately before study by anus. Dukes staging and resectability evaluation were made in 32 patients before surgery and meanwhile the results were compared with pathology. Results: Colonic anatomy and surrounding organs were clearly demonstrated on MRI in 40 patients with colonic cancer, particularly in recta and sigmoid flexure. The tumours showed iso-intensity on T 1 WI, iso-intensity or slight high-intensity signal on T 2 WI, and high-intensity signal on SPIR. Remarkable enhancement was seen in 35/40 (87.5%). Invasion of surrounding organs occurred in 8/40(20.0%) and MRI revealed 6; Meanwhile, MRI revealed lymph node metastasis in 8 out of 12 cases. 32 patients were regarded as resectable before surgery, and 8 patients as unresectable. Four patients were overestimated, the accuracy of preoperative evaluation for the resectability was 87.5%, and the detecting rate of colonic cancer was 100.0%. Conclusion: MRI can clearly show the colonic wall thickness, anatomic structure and surrounding anatomy. For the diagnosis of colonic cancer, MRI can not only demonstrate all its morphologic features, such as mass, thickened wall, and invasion of adjacent organs, but also swollen lymph node and metastasis in abdominal cavity. MRI is very helpful in the diagnosis, staging , and resectability evaluation of colonic cancer

Professional radiation protection societies and the international organizations – exploiting the synergies

Energy Technology Data Exchange (ETDEWEB)

Metcalf, Phil

2013-07-01

Radiation protection covers many disciplines from science through philosophy to law, and interacts with many human activities and endeavors. Professional societies for radiation protection were established and evolved throughout the second half of the twentieth century in many countries, and presently represent more than twenty thousand professionals working in more than fifty countries. During the same period a number of international organizations were established, some devoted to radiation safety, others with a role to play in radiation safety; such organizations being either independent non-governmental organizations or intergovernmental organizations of both regional and international dimensions. The national, regional and international radiation protection societies and associations have become the vehicle to provide this conduit from the profession to the international organizations. This is achieved by IRPA having representation within the relevant committees of the various international bodies, such as the Radiation Safety Standards Committee (RASSC) of the IAEA. At a national level radiation protection professionals can gain access to all international developments in radiation protection through the national societies and their interactions with IRPA and also as individual members of IRPA. The possibility to provide consolidated comment and feedback to the international organizations through national societies provides excellent opportunities for societies to organize national workshops and discussion platforms on all important areas of radiation protection.

Transported biofilms and their influence on subsequent macrofouling colonization.

Sweat, L Holly; Swain, Geoffrey W; Hunsucker, Kelli Z; Johnson, Kevin B

2017-05-01

Biofilm organisms such as diatoms are potential regulators of global macrofouling dispersal because they ubiquitously colonize submerged surfaces, resist antifouling efforts and frequently alter larval recruitment. Although ships continually deliver biofilms to foreign ports, it is unclear how transport shapes biofilm microbial structure and subsequent macrofouling colonization. This study demonstrates that different ship hull coatings and transport methods change diatom assemblage composition in transported coastal marine biofilms. Assemblages carried on the hull experienced significant cell losses and changes in composition through hydrodynamic stress, whereas those that underwent sheltered transport, even through freshwater, were largely unaltered. Coatings and their associated biofilms shaped distinct macrofouling communities and affected recruitment for one third of all species, while biofilms from different transport treatments had little effect on macrofouling colonization. These results demonstrate that transport conditions can shape diatom assemblages in biofilms carried by ships, but the properties of the underlying coatings are mainly responsible for subsequent macrofouling. The methods by which organisms colonize and are transferred by ships have implications for their distribution, establishment and invasion success.

Staphylococcus aureus in the community: colonization versus infection.

Directory of Open Access Journals (Sweden)

Maureen Miller

Full Text Available BACKGROUND: Antibiotic-resistant Staphylococcus aureus infections have increased dramatically in the community, yet S. aureus nasal colonization has remained stable. The objectives of this study were to determine if S. aureus colonization is a useful proxy measure to study disease transmission and infection in community settings, and to identify potential community reservoirs. METHODOLOGY/PRINCIPAL FINDINGS: Randomly selected households in Northern Manhattan, completed a structured social network questionnaire and provided nasal swabs that were typed by pulsed field gel electrophoresis to identify S. aureus colonizing strains. The main outcome measures were: 1 colonization with S. aureus; and 2 recent serious skin infection. Risk factor analyses were conducted at both the individual and the household levels; logistic regression models identified independent risks for household colonization and infection. RESULTS: 321 surveyed households contained 914 members. The S. aureus prevalence was 25% and MRSA was 0.4%. More than 40% of households were colonized. Recent antibiotic use was the only significant correlate for household colonization (p = .002. Seventy-eight (24% households reported serious skin infection. In contrast with colonization, five of the six risk factors that increased the risk of skin infection in the household at the univariate level remained independently significant in multivariable analysis: international travel, sports participation, surgery, antibiotic use and towel sharing. S. aureus colonization was not significantly associated with serious skin infection in any analysis. Among multiperson households with more than one person colonized, 50% carried the same strain. CONCLUSIONS/SIGNIFICANCE: The lack of association between S. aureus nasal colonization and serious skin infection underscores the need to explore alternative venues or body sites that may be crucial to transmission. Moreover, the magnitude of colonization and

Child organ trafficking: global reality and inadequate international response.

Bagheri, Alireza

2016-06-01

In organ transplantation, the demand for human organs has grown far faster than the supply of organs. This has opened the door for illegal organ trade and trafficking including from children. Organized crime groups and individual organ brokers exploit the situation and, as a result, black markets are becoming more numerous and organized organ trafficking is expanding worldwide. While underprivileged and vulnerable men and women in developing countries are a major source of trafficked organs, and may themselves be trafficked for the purpose of illegal organ removal and trade, children are at especial risk of exploitation. With the confirmed cases of children being trafficked for their organs, child organ trafficking, which once called a "modern urban legend", is a sad reality in today's world. By presenting a global picture of child organ trafficking, this paper emphasizes that child organ trafficking is no longer a myth but a reality which has to be addressed. It argues that the international efforts against organ trafficking and trafficking in human beings for organ removal have failed to address child organ trafficking adequately. This chapter suggests that more orchestrated international collaboration as well as development of preventive measure and legally binding documents are needed to fight child organ trafficking and to support its victims.

INMARSAT - The International Maritime Satellite Organization: Origins and structure

Doyle, S. E.

1977-01-01

The third session of the International Conference on the Establishment of an International Maritime Satellite System established the International Maritime Satellite Organization (INMARSAT) in 1976. Its main functions are to improve maritime communications via satellite, thereby facilitating more efficient emergency communications, ship management, and maritime public correspondence services. INMARSAT's aims are similar to those of the Intergovernmental Maritime Consultative Organization (IMCO), the main United Nations organization dealing with maritime affairs. The specific functions of INMARSAT have been established by an Intersessional Working Group (IWG) which met three times between general conference meetings. Initial investment shares for the creation of INMARSAT were shared by the United States (17%), the United Kingdom (12%), the U.S.S.R. (11%), Norway (9.50%), Japan (8.45%), Italy (4.37%), and France (3.50%).

Benjamin N. Rollo

2016-01-01

Full Text Available Background & Aims: Hirschsprung disease (HSCR is caused by failure of cells derived from the neural crest (NC to colonize the distal bowel in early embryogenesis, resulting in absence of the enteric nervous system (ENS and failure of intestinal transit postnatally. Treatment is by distal bowel resection, but neural cell replacement may be an alternative. We tested whether aneuronal (aganglionic colon tissue from patients may be colonized by autologous ENS-derived cells. Methods: Cells were obtained and cryopreserved from 31 HSCR patients from the proximal resection margin of colon, and ENS cells were isolated using flow cytometry for the NC marker p75 (nine patients. Aneuronal colon tissue was obtained from the distal resection margin (23 patients. ENS cells were assessed for NC markers immunohistologically and by quantitative reverse-transcription polymerase chain reaction, and mitosis was detected by ethynyl-2′-deoxyuridine labeling. The ability of human HSCR postnatal ENS-derived cells to colonize the embryonic intestine was demonstrated by organ coculture with avian embryo gut, and the ability of human postnatal HSCR aneuronal colon muscle to support ENS formation was tested by organ coculture with embryonic mouse ENS cells. Finally, the ability of HSCR patient ENS cells to colonize autologous aneuronal colon muscle tissue was assessed. Results: ENS-derived p75-sorted cells from patients expressed multiple NC progenitor and differentiation markers and proliferated in culture under conditions simulating Wnt signaling. In organ culture, patient ENS cells migrated appropriately in aneural quail embryo gut, and mouse embryo ENS cells rapidly spread, differentiated, and extended axons in patient aneuronal colon muscle tissue. Postnatal ENS cells derived from HSCR patients colonized autologous aneuronal colon tissue in cocultures, proliferating and differentiating as neurons and glia. Conclusions: NC-lineage cells can be obtained from HSCR�

Assessing Summit Engagement with Other International Organizations in Global Governance

Directory of Open Access Journals (Sweden)

Marina Larionova

2016-03-01

Full Text Available Recent decades have witnessed dramatic changes all over the world. One major trend is the proliferation and diversification of actors, forums and their arrangements to address global governance challenges, which has led to fragmentation in global governance. However, such contested multilateralism has a positive dimension, as the emergence of informal multilateral institutions claiming a major role in defining the global governance agenda creates alternatives for providing common goods. New arrangements acquire their own actorness and place in the system of global governance. In certain policy areas, there is a clear trend for the new summit institutions’ leadership. The most visible recent cases include the Group of 20 (G20, the BRICS group of Brazil, Russia, India, China and South Africa, and the Asia-Pacific Economic Cooperation (APEC forum, with APEC gaining importance regionally and globally. These new informal groupings work on their own agenda. They also engage with established international organizations to steer global governance processes. Taken together, the transformative trends in international relations, the emergence of new actors, tensions between exclusive and inclusive clubs, and demands for the legitimacy and effectiveness of the international institutions define the relevance of the study, systematization and comparative analysis of the effectiveness of this model of cooperation among international institutions. This article builds an analytical framework by undertaking three tasks. It first reviews the key concepts. Second, it argues for a rational choice institutionalist approach. Third, it puts forward a hypothesis for research: to compensate for their inefficiencies, summit institutions engage with other international organizations in a mode they regard most efficient for attainment of their goals. The modes of those institutions’ engagement with other international organizations as reflected in the leaders�

Internal marketing within a health care organization: developing an implementation plan.

Science.gov (United States)

Hallums, A

1994-05-01

This paper discusses how the concept of internal marketing can be applied within a health care organization. In order to achieve a market orientation an organization must identify the needs and wants of its customers and how these may change in the future. In order to achieve this, internal marketing is a necessary step to the implementation of the organizations marketing strategy. An outline plan for the introduction of an internal marketing programme within an acute hospital trust is proposed. The plan identifies those individuals and departments who should be involved in the planning and implementation of the programme. The benefits of internal marketing to the Trust are also considered.

Citrobacter rodentium, which colonizes the gut mucosa via formation of attaching and effacing (A/E) lesions, causes transmissible colonic hyperplasia. The aim of this study was to evaluate whether prophylactic treatment with Bifidobacterium breve UCC2003 can improve the outcome of C. rodentium infection. Six-week-old albino C57BL/6 mice were pre-treated for 3 days with B. breve, challenged with bioluminescent C. rodentium and administered B. breve or PBS-C for 8 days post-infection; control mice were either administered B. breve and mock-infected with PBS, or mock-treated with PBS-C and mock-infected with PBS. C. rodentium colonization was monitored by bacterial enumeration from faeces and by a combination of both 2D bioluminescence imaging (BLI) and composite 3D diffuse light imaging tomography with µCT imaging (DLIT-µCT). At day 8 post-infection, colons were removed and assessed for crypt hyperplasia, histology by light microscopy, bacterial colonization by immunofluorescence, and A/E lesion formation by electron microscopy. Prophylactic administration of B. breve did not prevent C. rodentium colonization or A/E lesion formation. However, this treatment did alter C. rodentium distribution within the large intestine and significantly reduced colonic crypt hyperplasia at the peak of bacterial infection. These results show that B. breve could not competitively exclude C. rodentium, but reduced pathogen-induced colonic inflammation.

Full Text Available Problem setting: Personalized activity of individuals holding offices of individual organs in the structure of international organizations is an essential part of the activities of these organizations. Meanwhile, today legal science researches this problem mainly in the context of the development of separate branches of international law. Recent research and publications analysis: From Max Weber, the development of individual organs was studied as a question how one transforms institutions that are led by high-profile individuals into institutions that have a life and energy of their own". Current international legal research in this regard provided by  H. H. Koh, F. Benua-Romer, H. Klebes, R. Kicker and the others. There are no relevant Ukrainian legal studies on this issue today. Paper objective: The purpose of the article is to review the issue on the example of a relatively new international bodies - the UN High Commissioner for Human Rights and the Commissioner for Human Rights of the Council of Europe. The features of organs, crucial for the study are: the features of appointment (election of candidate, term of his office and special activities scheduled for each of these positions. Paper main body: Comparing the Institute of the High Commissioner and the Commissioner for Human Rights of the Council of Europe in personological view, we note that the personal characteristics and expert practices of the first, second and third Council of Europe Commissioner largely matches with the same first three (in same order United Nations High Commissioners for Human Rights. This fact suggests that the election of candidates for these positions is a part of strategic transformation of the body. There is a reason to believe that the strategy of the international organizations, not only related to their desire to be effectively involved in actions within their mandate, but also with the desire to increase their influence in comparison with the

A biopsy was performed, and tuberculous enteritis with chronic granulomatous inflammation was diagnosed. Intestinal tuberculosis is most frequent in the ileocecal area, followed by the ascending colon, transverse colon, duodenum, stomach, and sigmoid c...

Fungal colonization of air-conditioning systems

Full Text Available Fungi have been implicated as quantitatively the most important bioaerosol component of indoor air associated with contaminated air-conditioning systems. rarely, indoor fungi may cause human infections, but more commonly allergenic responses ranging from pneumonitis to asthma-like symptoms. From all air conditioner filters analyzed, 16 fungal taxa were isolated and identified. Aspergillus fumigatus causes more lethal infections worldwide than any other mold. Air-conditioning filters that adsorb moisture and volatile organics appear to provide suitable substrates for fungal colonization. It is important to stress that fungal colonization of air-conditioning systems should not be ignored, especially in hospital environments.

Colonic volvulus is a relatively uncommon cause of large bowel obstruction usually involving mobile, intra-peritoneal, colonic segments. Congenital or acquired anatomic variation may be associated with an increased risk of colonic volvulus which can occasionally involve retro-peritoneal segments. We report a case of 54-year-old female who presented to our Institution to perform a plain abdominal film series for acute onset of cramping abdominal pain. Both the upright and supine films showed signs of acute colonic obstruction which was thought to be due to an internal hernia of the transverse colon into the lesser sac. The patient was therefore submitted to a multi-detector contrast-enhanced computed tomography (CT). CT findings were initially thought to be consistent with the presumed diagnosis of internal hernia but further evaluation and coronal reformatting clearly depicted the presence of a colonic volvulus possibly resulting from a retro-gastric colon. At surgery, a volvulus of the ascending colon was found and a right hemi-colectomy had to be performed. However, a non rotated midgut with a right-sided duodeno-jejunal flexure and a left sided colon was also found at laparotomy and overlooked in the pre-operative CT. Retrospective evaluation of CT images was therefore performed and a number of CT signs of intestinal malrotation could be identified.

Legislative/regulatory drivers the international maritime organization

Wallace, S.A.

1992-01-01

I am pleased and honored to be here representing the International Maritime Organization (IMO), which is the cosponsor of this R ampersand D Forum with the Coast Guard. This is truly an international Forum - and it needs to be. I should like to turn now to the subject of IMO and, for the benefit of many here who do not know the Organization, describe very briefly what IMO is and what it does. IMO is the specialized agency of the United Nations that deals with shipping matters. The Organization has 136 member-states and its headquarters is located in London on the bank of the Thames River. It has a permanent secretariat numbering about 300 international civil servants, headed by the Secretary-General. IMO is a technical organization, and it conducts its work through committees of the whole, with the help of standing subcommittees, working groups, and other groups or bodies formed as the need arises. We have with us today a representative of MED in the person of Commander David Pascoe, whom the U.S. Coast Guard has seconded to IMO for a two-year tour of duty. The purposes of IMO are, in short, to improve safety at sea and to prevent pollution from ships; i.e., IMO continuously strives for safer ships and cleaner oceans. IMO also promotes technical cooperation and assistance, particularly among developing countries, to help satisfy these purposes globally. The work product of IMO includes more than 30 multilateral treaties and 600 codes and sets of recommendations on maritime safety, marine environment protection, and other legal and technical issues involving worldwide shipping

Principles of the institutional law of international organizations

Amerasinghe-Chittharanjan, Felix

1996-01-01

Dr Amerasinghe starts with a brief history of international organizations. In fourteen substantive chapters, he then deals with subjects such as interpretation, membership and representation, the doctrine of "ultra vires", responsibility, liability of members to third parties, internal law and employment relations, privileges and immunities, dispute settlement, and, finally, dissolution and succession. There is a full and detailed examination of the problems connected with each of these subjects. The primary object of the book is to discuss principles, but Dr Amerasinghe also studies the law and practice of different organizations, using a rigourous analysis of the material alongside his functional examination of the law.

Colonization by benthic macroinvertebrates in two artificial substrate types of a Riparian Forest

Directory of Open Access Journals (Sweden)

Lívia Borges dos Santos

Full Text Available Abstract: Aim To analyze the efficiency of organic and inorganic substrates in samples of benthic macroinvertebrates of riparian forests from the Cerrado. Specific objectives (i characterize the ecological succession and taxonomic richness of benthic macroinvertebrates in stream affluent of a riparian forest; (ii analyze the influence of seasonality on the colonization of macroinvertebrates; and (iii determine the effect of the types of artificial substrates on the richness, composition and abundance of the benthic community. Methods Sampling was carried out in the rainy and dry seasons, and we installed in the watercourse two types of substrates: organic (leaf packs and inorganic (bricks, organized in pairs. Six samples per season were done to verify colonization, succession, richness and abundance of benthic community. The substrates were carefully sorted and the organisms were identified to the lowest possible taxonomic level. Results The ecological succession was clearly observed, with the initial occurrence of Chironomidae and Baetidae (considered early colonizers, and a late occurrence of organisms such as Helotrephidae and Trichoptera (considered late colonizers. No significant difference was found in the richness and abundance among the studied seasons (rainy and dry, but the organic substrate was significantly higher than the inorganic substrate for these parameters. Conclusion Organic artificial substrates are more efficient in characterizing the community of benthic macroinvertebrates in the study area, because they are more similar to the conditions of the substrate found naturally in the environment.

Full Text Available Colon cancer is a world-wide health problem and the second-most dangerous type of cancer, affecting both men and women. The modern diet and lifestyles, with high meat consumption and excessive alcohol use, along with limited physical activity has led to an increasing mortality rate for colon cancer worldwide. As a result, there is a need to develop novel and environmentally benign drug therapies for colon cancer. Currently, nutraceuticals play an increasingly important role in the treatment of various chronic diseases such as colon cancer, diabetes and Alzheimer׳s disease. Nutraceuticals are derived from various natural sources such as medicinal plants, marine organisms, vegetables and fruits. Nutraceuticals have shown the potential to reduce the risk of colon cancer and slow its progression. These dietary substances target different molecular aspects of colon cancer development. Accordingly, this review briefly discusses the medicinal importance of nutraceuticals and their ability to reduce the risk of colorectal carcinogenesis.

The Clinical Practice Guidelines Committee is composed of society members who are chosen because they have demonstrated expertise in the specialty of colon and rectal surgery. This committee was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus. This is accompanied by developing Clinical Practice Guidelines based on the best available evidence. These guidelines are inclusive and not prescriptive. Their purpose is to provide information on which decisions can be made, rather than to dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, health care workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. It should be recognized that these guidelines should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all the circumstances presented by the individual patient.

How to Brand an International Organization. NATO Case Study

Directory of Open Access Journals (Sweden)

Gigi Mihaita

2011-05-01

Full Text Available Branding products and companies has always been associated with private enterprises and less, if ever, with international intergovernmental organizations. International organizations now have a long history behind them, a history often marked by contradictory events. In the last decade the international organizations developed their own public relations department in an attempt to communicate promptly and transmit the general audience their version of reality. Having this in mind we will try to briefly present in the current work the main reasons why we believe that the international organizations, NATO in particular, have started to see themselves as brand and to create a so called “commercial identity” by becoming a brand. By applying the conceptual and analytical framework used in analyzing the marketing strategies of the private companies we will try to see whether NATO is about to become a brand. Our starting point will be a 2008 statement of Jean-François Bureau, deputy general secretary responsible with NATO’s public diplomacy: “We have the green light to think about a branding policy for NATO”. Nowadays global society, perceptions tend to become more important than reality itself, and thus positive perceptions tend to become crucial. NATO has suffered an image decline in the last decade, therefore some new communication measures tend to impose themselves. The distinction between soft power and propaganda must be carefully analyzed when we speak about branding NATO. Thus we hope to bring some necessary clarifications in the area of NATO branding. Is there a brand? Is a brand going to be constructed? How does it differ from a commercial society? Does NATO need its own TV channel? Raising questions and offering a new perspective is, in the end, our primary goal, as a debate on this subject is a must that offers a new perspective in the area of theory of international organizations.

G20: Engaging with International Organizations to Generate Growth

Directory of Open Access Journals (Sweden)

Marina Larionova

2017-08-01

Full Text Available Born in response to economic and financial crises which existing institutions were unable to address adequately, the G20 transformed from a crisis management group into the premier forum for international economic cooperation. Like its predecessor, the G7 (which was set up in 1975, and BRICS (established in 2009, G20 is an informal club or summit institution. To ensure continuity, legitimacy and efficiency in fulfilling their global governance functions of deliberation, direction-setting, decision-making, delivery and the development of global governance, the G20 members engage other international organizations. It is hypothesized that to maximize benefits from its engagement with international organizations, the G20 resorts to a combination of the “catalyst”, “core group” and “parallel treatment” approaches exercised by summit institutions. These include exerting an influence in promoting changes to international organizations through endorsement or stimulus, compelling them to reform, imparting a new direction by giving a lead that the other organizations would follow, and creating original mechanisms, working in parallel with existing institutions. The article tests this assumption. To trace the dynamics of G20 engagement with multilateral organizations and identify preferred models across the presidencies and policy areas, the analysis is carried out within the rational choice institutionalist paradigm, drawing on the quantitative and qualitative analysis of documents adopted by the G20. Findings from the study indicate that the intensity of the G20 engagement with the IOs is very high and G20 mostly resorts to a combination of the catalyst and core group approaches, though the pattern depends on the policy area, the IOs and the presidency agenda. The intensity of G20 engagement with the IMF, Financial Stability Board, World Bank, and Organization for Economic Co-operation and Development by far exceeds the intensity of its

Sulphur mustard (SM) is a chemical warfare agent that attacks mainly skin, eye and lungs. Due to its lipophilic properties, SM is also able to diffuse through the skin and reach internal organs. DNA represents one of the most critical molecular targets of this powerful alkylating agent which modifies DNA structure by forming monoadducts and biadducts. These DNA lesions are involved in the acute toxicity of SM as well as its long-term carcinogenicity. In the present work we studied the formation and persistence of guanine and adenine monoadducts and guanine biadducts in the DNA of brain, lungs, kidneys, spleen, and liver of SKH-1 mice cutaneously exposed to 2, 6 and 60 mg/kg of SM. SM-DNA adducts were detected in all studied organs, except in liver at the two lowest doses. Brain and lungs were the organs with the highest level of SM-DNA adducts, followed by kidney, spleen and liver. Monitoring the level of adducts for three weeks after cutaneous exposure showed that the lifetime of adducts were not the same in all organs, lungs being the organ with the longest persistence. Diffusion from skin to internal organs was much more efficient at the highest compared to the lowest dose investigated as the result of the loss of the skin barrier function. These data provide novel information on the distribution of SM in tissues following cutaneous exposures and indicate that brain is an important target. - Highlights: • Sulphur mustard reaches internal organs after skin exposure • Adducts are detected in the DNA of internal organs • Brain is the organ with the highest level of DNA damage • The barrier function of skin is lost at high dose of sulphur mustard • DNA adducts persist in organs for 2 or 3 weeks.

Volunteer satisfaction: Internal structure and relationship with permanence in organizations. The concept of satisfaction is considered theoretically relevant in practically all the studies that have investigated the factors that influence the permanence of volunteer participation in organizations. However, the practical results are not conclusive, perhaps due to the wide range of ways in which the concept is understood and measured. The object of this study is: to analyse the internal structure of satisfaction and to verify its relationship with volunteer duration in organizations. The results of the factor analysis yield a three-factor structure: Satisfaction with the management of the organization, Satisfaction with the tasks, Satisfaction of motivations. The three factors allow us to differentiate between individuals who remain in the organization for a period of 12 consecutive months, and those who leave earlier. The results of structural equation model analysis show that the relationship between satisfaction and the length of time that volunteers stay with the organization is affected by the intention to remain.

Ecology of root colonizing Massilia (Oxalobacteraceae.

Full Text Available BACKGROUND: Ecologically meaningful classification of bacterial populations is essential for understanding the structure and function of bacterial communities. As in soils, the ecological strategy of the majority of root-colonizing bacteria is mostly unknown. Among those are Massilia (Oxalobacteraceae, a major group of rhizosphere and root colonizing bacteria of many plant species. METHODOLOGY/PRINCIPAL FINDINGS: The ecology of Massilia was explored in cucumber root and seed, and compared to that of Agrobacterium population, using culture-independent tools, including DNA-based pyrosequencing, fluorescence in situ hybridization and quantitative real-time PCR. Seed- and root-colonizing Massilia were primarily affiliated with other members of the genus described in soil and rhizosphere. Massilia colonized and proliferated on the seed coat, radicle, roots, and also on hyphae of phytopathogenic Pythium aphanidermatum infecting seeds. High variation in Massilia abundance was found in relation to plant developmental stage, along with sensitivity to plant growth medium modification (amendment with organic matter and potential competitors. Massilia absolute abundance and relative abundance (dominance were positively related, and peaked (up to 85% at early stages of succession of the root microbiome. In comparison, variation in abundance of Agrobacterium was moderate and their dominance increased at later stages of succession. CONCLUSIONS: In accordance with contemporary models for microbial ecology classification, copiotrophic and competition-sensitive root colonization by Massilia is suggested. These bacteria exploit, in a transient way, a window of opportunity within the succession of communities within this niche.

Celiac disease (CD), a systemic autoimmune disorder that typically involves duodenal mucosa, can also affect other intestinal areas. Duodenal and oral mucosa organ culture has already been demonstrated as a reliable procedure to identify CD. The present study investigated gluten-dependent immunological activation of colonic mucosa in CD patients. We took advantage of the numerous colonoscopies performed for various clinical conditions or only for defensive medicine. Forty-four patients with gastrointestinal symptoms or in need of colorectal cancer screening were divided into patients with serum anti-endomysium (EMA) and anti-tissue transglutaminase (anti-tTG) antibody positive results (Group A), patients with serum antibody negative results (Group B), and patients with inflammatory bowel disease (IBD) (Group C). The autoantibodies EMA and anti-tTG were evaluated in supernatants of cultured sigmoid and duodenal biopsies from patients on a gluten-containing diet. In Group A, EMA and anti-tTG resulted positive in all duodenal culture supernatants. In sigmoid culture supernatants, EMA and anti-tTG were detected in 12/16 (75 %) and 13/16 (81.3 %) patients, respectively. In Group B, none of the 17 patients showed EMA and anti-tTG positive results in both duodenal and sigmoid cultures. In Group C, all 11 patients presented EMA negative results in sigmoid cultures. Only in one patient, anti-tTG were detectable in the sigmoid culture supernatant, as expected in cases of IBD. Data confirm that the gluten-dependent immunological activation affects more intestinal tracts with different degrees of involvement, suggesting that the organ culture of colonic biopsies could represent a new tool to opportunistically detect CD.

This article takes up the challenge of redressing this by examining the origins and policies of Christian agencies such as Medicus Mundi Internationalis (International Organisation for Medical Cooperation and the World Council of Churches Christian Medical Commission. Despite denominational and theological differences a story emerges of a common trajectory from a hospital-based focus on curative medicine to community-focused primary healthcare in the three decades or so after 1945.

Hospitalized Premature Infants Are Colonized by Related Bacterial Strains with Distinct Proteomic Profiles

Full Text Available During the first weeks of life, microbial colonization of the gut impacts human immune system maturation and other developmental processes. In premature infants, aberrant colonization has been implicated in the onset of necrotizing enterocolitis (NEC, a life-threatening intestinal disease. To study the premature infant gut colonization process, genome-resolved metagenomics was conducted on 343 fecal samples collected during the first 3 months of life from 35 premature infants housed in a neonatal intensive care unit, 14 of whom developed NEC, and metaproteomic measurements were made on 87 samples. Microbial community composition and proteomic profiles remained relatively stable on the time scale of a week, but the proteome was more variable. Although genetically similar organisms colonized many infants, most infants were colonized by distinct strains with metabolic profiles that could be distinguished using metaproteomics. Microbiome composition correlated with infant, antibiotics administration, and NEC diagnosis. Communities were found to cluster into seven primary types, and community type switched within infants, sometimes multiple times. Interestingly, some communities sampled from the same infant at subsequent time points clustered with those of other infants. In some cases, switches preceded onset of NEC; however, no species or community type could account for NEC across the majority of infants. In addition to a correlation of protein abundances with organism replication rates, we found that organism proteomes correlated with overall community composition. Thus, this genome-resolved proteomics study demonstrated that the contributions of individual organisms to microbiome development depend on microbial community context.

Today majority of scientists become an interesting phenomenon decision of international organizations which are increasingly sound as a category of "soft law" and its influence on the development of international law in general. International organizations cease to be the "second" subject of international law, and if you have not won the first place, it is only a matter of time. In the article the role of soft law in the mechanism of international organizations functioning are shown, the legal nature and impact of these acts on the member states. In our opinion, norms of "soft law", as a rule, contained in resolutions of international organizations are non-binding and do not formally bind member states. Norms of "soft law" are often adheres by the states and moreover are implemented into the national legal systems by incorporating similar in content standards into the national legislation. This is due to the fact that norms of "soft law" has a weight of moral and political significance and, as a rule, are created by organizations that have a considerable authority. Jurists generally distinguish two kinds of acts of recommendatory force: model acts (laws and recommended acts which are not model, adopted in the framework of international organizations. In this connection the question of each mentioned method influence on the legislation of state. In our opinion, one of distinguishing features of the model recommendatory acts has is quite limited influence on the law of states and a narrow scope. At the same time, recommendatory acts of some specialized international organizations have a more complex effect on the development of national legislation, contain the highest level of standards, and as well develop international treaty provisions.

Actomyosin-based Self-organization of cell internalization during C. elegans gastrulation

Pohl Christian

2012-11-01

Full Text Available Abstract Background Gastrulation is a key transition in embryogenesis; it requires self-organized cellular coordination, which has to be both robust to allow efficient development and plastic to provide adaptability. Despite the conservation of gastrulation as a key event in Metazoan embryogenesis, the morphogenetic mechanisms of self-organization (how global order or coordination can arise from local interactions are poorly understood. Results We report a modular structure of cell internalization in Caenorhabditis elegans gastrulation that reveals mechanisms of self-organization. Cells that internalize during gastrulation show apical contractile flows, which are correlated with centripetal extensions from surrounding cells. These extensions converge to seal over the internalizing cells in the form of rosettes. This process represents a distinct mode of monolayer remodeling, with gradual extrusion of the internalizing cells and simultaneous tissue closure without an actin purse-string. We further report that this self-organizing module can adapt to severe topological alterations, providing evidence of scalability and plasticity of actomyosin-based patterning. Finally, we show that globally, the surface cell layer undergoes coplanar division to thin out and spread over the internalizing mass, which resembles epiboly. Conclusions The combination of coplanar division-based spreading and recurrent local modules for piecemeal internalization constitutes a system-level solution of gradual volume rearrangement under spatial constraint. Our results suggest that the mode of C. elegans gastrulation can be unified with the general notions of monolayer remodeling and with distinct cellular mechanisms of actomyosin-based morphogenesis.

Luciene Aparecida Leite-Rossi

Full Text Available AIM: The aim was to compare the kinetics of decomposition and the colonization of leaf litter of two plant species, the native Talauma ovata (pinha-do-brejo and the exotic Saccharum officinarum (sugarcane, by aquatic macroinvertebrates; METHODS: From each substrate, three recipients of colonization were taken from a stream, and the specimens identified to the lowest taxonomic level on days 7, 15, 34, 44, 61 and 75. The debris was weighed at the beginning and end of the experiment and determined their cell wall fractions; RESULTS: The coefficients of mineralization indicated higher velocity decay of organic matter refractory in T. ovata. There was no difference in taxonomic structure of macroinvertebrates, between the two substrates, but the community exhibited distinct functional feeding groups in the peak of colonization, with a greater number of shredders in T. ovata. The successive states of decomposition of the two plant detritus showed distinct macroinvertebrate densities; CONCLUSIONS: The amount and state of the plant biomass were important factors influencing the density and diversity of the macroinvertebrate fauna throughout the process of organic decomposition.

Full Text Available In the present article author reveals the order of creation, structure, aims and objectives of national and international intergovernmental aeronautical organizations, governing procedure for flight operations and providing direct air traffic control over sovereign territory and abroad. In this article, author notes that in the world there are three main organizational and legal forms of air traffic control systems to ensure coordination between civil and military air navigation services (agencies. In the Russian Federation, author notes that air navigation services on behalf of the State are made by the State Corporation for Air Traffic Management that has the legal status of the commercial organization - the Federal State Unitary Enterprise. Author analyzes the work of the Organization for the Civil Air Navigation Services (CANSO, the International Federation of Air Traffic Controllers (IFATCA. During the study author also concludes that in the past decade, there is the steady trend of transferring functions of air navigation from the State to commercial organizations (joint stock companies and limited liability companies, which are financed from the funds received as payment for air traffic services. The responsibility for the improper maintenance of international air navigation, of course, is borne by the State. Author notes that regional and international intergovernmental aeronautical organizations operate in respect of all aircraft (public, civil, experimental, i.e., perform general air navigation, unlike ICAO, which takes standards and recommended practices, rules and procedures for safety and air traffic services only to civil aircraft, that does not ensure the creation of a regulatory framework for the global unification of aeronautical processes.

DDR and the Internal Organization of Non-State Armed Groups

Directory of Open Access Journals (Sweden)

Brian McQuinn

2016-03-01

Full Text Available This paper argues that demobilization, disarmament and reintegration (DDR trajectories of non-state armed groups are shaped by a group’s internal organization. Extensive research by political scientists has demonstrated a correlation between internal features of armed groups and their behaviour (e.g. extent of violence used against local communities. I extend this analysis to DDR outcomes by illustrating how two features of an armed group’s internal organization – command profile and financing architecture – influence post-conflict DDR trajectories. To substantiate the theory, four case studies from Colombia, Nepal and Libya are reviewed. The article concludes with the limitations and opportunities of this approach, including the potential of predicting DDR challenges.

Space exploration and colonization - Towards a space faring society

Science.gov (United States)

Hammond, Walter E.

1990-01-01

Development trends of space exploration and colonization since 1957 are reviewed, and a five-phase evolutionary program planned for the long-term future is described. The International Geosphere-Biosphere program which is intended to provide the database on enviromental changes of the earth as a global system is considered. Evolution encompasses the anticipated advantages of such NASA observation projects as the Hubble Space Telescope, the Gamma Ray Observatory, the Advanced X-Ray Astrophysics Facility, and the Cosmic Background Explorer. Attention is given to requirements for space colonization, including development of artificial gravity and countermeasures to mitigate zero gravity problems; robotics and systems aimed to minimize human exposure to the space environment; the use of nuclear propulsion; and international collaboration on lunar-Mars projects. It is recommended that nuclear energy sources be developed for both propulsion and as extraterrestrial power plants.

Colon trauma is frequent and its prevalence is difficult to establish because of the different factors that intervene in its origin. In Mexico, traumatic colon injuries, albeit stab wounds or gunshot wounds, are on the rise. Our objective was to evaluate the most appropriate management for traumatic colon injuries. We conducted a retrospective study of 178 case files of patients with abdominal trauma and colon lesions during a 5-year period from January 2003 to June 2008 from the General Hospital of Balbuena, Mexico City. The study compared the use of primary closure vs. colostomy, analyzing variables such as sex, age, type of wound, severity of lesion and mortality. There were a total of 178 patients; 156 were male (87.6%) and 22 were female (12.4%). The most affected age group was between 21 and 30 years; 74 patients (41.6%) had stab wounds and 104 patients (58.4%) had gunshot wounds. Management consisted mainly of primary closure in 92 cases (51.7%) vs. colostomy in 86 patients (48.3%). However, 64% of gunshot wounds were treated with colostomy. Reported mortality was 9.55% and this was due to different factors such as multiple organ injury. Treatment of traumatic colon injury should be case specific, taking into account the mechanism of the lesion, its severity and associated injuries.

In attemption to determine the place of primary repair in management of colon injuries, an open, non randomized clinical study was performed. Retrospective (RS) group of 62 patients according to exclusion criteria by Stone (S/F) and Flint (F1) was managed by one or two stage surgical procedure. Prospective (PR) group of 34 patients was managed using one stage repair non-selectively: two stage procedures were performed in 3 cases of advanced peritonitis and multi-segmental lacerations with impaired circulation of colon. In RS group 36 patients were managed by primary repair and in PR group, 31 were managed by primary repair. Both groups were of similar age/sex. Indexes of trauma severity were similar (TS, ISS, PATI). The latent time was shorter in PR group. Associated injuries to other body regions and abdominal organs were similar in both groups. S/F criteria and Flint grading in both (RS vs. PR) groups were similar. Comparison of attempted and successful primary repairs justifies the more liberal use of primary repair in early management of colon injuries.

Patients with advanced colorectal cancer have a high incidence of postoperative complications. We sought to identify outcomes of patients who underwent resection for colon cancer by cancer stage. The National Surgical Quality Improvement Program database was used to evaluate all patients who underwent colon resection with a diagnosis of colon cancer from 2012 to 2014. Multivariate logistic regression analysis was performed to investigate patient outcomes by cancer stage. A total of 7,786 colon cancer patients who underwent colon resection were identified. Of these, 10.8% had metastasis at the time of operation. Patients with metastatic disease had significantly increased risks of perioperative morbidity (adjusted odds ratio [AOR]: 1.44, P = .01) and mortality (AOR: 3.72, P = .01). Patients with metastatic disease were significantly younger (AOR: .99, P colon cancer have metastatic disease. Postoperative morbidity and mortality are significantly higher than in patients with localized disease. Published by Elsevier Inc.

AIM: To see the possibility of avoiding routine colostomy in patients presenting with unprepared bowel. METHODS: The cohort is composed of 103 patients, of these, 86 patients presented as emergencies (self-inflected and iatrogenic colon injuries, stab wounds and blast injury of the colon, volvulus sigmoid, obstructing left colon cancer, and strangulated ventral hernia). Another 17 patients were managed electively for other colon pathologies. During laparotomy, the involved segment was resected and the two ends of the colon were brought out via a separate colostomy wound. One layer of interrupted 3/0 silk was used for colon anastomosis. The exteriorized segment was immediately covered with a colostomy bag. Between the 5th and 7th postoperative day, the colon was easily dropped into the peritoneal cavity. The defect in the abdominal wall was closed with interrupted nonabsorbable suture. The skin was left open for secondary closure. RESULTS: The mean hospital stay (± SD) was 11.5 ± 2.6 d (8-20 d). The exteriorized colon was successfully dropped back into the peritoneal cavity in all patients except two. One developed a leak from oesophago-jejunostomy and from the exteriorized colon. She subsequently died of sepsis and multiple organ failure (MOF). In a second patient the colon proximal to the exteriorized anastomosis prolapsed and developed severe serositis, an elective ileo-colic anastomosis (to the left colon) was successfully performed. CONCLUSION: Exteriorized colon anastomosis is simple, avoids the inconvenience of colostomy and can be an alternative to routine colostomy. It is suitable where colostomy is socially unacceptable or the facilities and care is not available. PMID:17589900

The demand for international volunteer experiences to promote global health and nutrition is increasing and numerous studies have documented the experiences of the international volunteers who travel abroad; however, little is known about effective practices from the perspective of partner organizations. This study aims to understand how variables such as the skill-level of volunteers, the duration of service, cultural and language training, and other key variables affect partner organizations' perceptions of volunteer effectiveness at promoting healthcare and nutrition. This study used a cross-sectional design to survey a convenience sample of 288 volunteer partner organizations located in 68 countries. Principle components analyses and manual coding of cases resulted in a categorization of five generalized types of international volunteering. Differences among these types were compared by the duration of service, skill-level of volunteers, and the volunteers' perceived fit with organizational needs. In addition, a multivariate ordinary least square regression tested associations between nine different characteristics/activities and the volunteers' perceived effectiveness at promoting healthcare and nutrition. Partner organizations viewed highly-skilled volunteers serving for a short-term abroad as the most effective at promoting healthcare and nutrition in their organizations, followed by slightly less-skilled long-term volunteers. The greatest amount of variance in perceived effectiveness was volunteers' ability to speak the local language, followed by their skill level and the duration of service abroad. In addition, volunteer training in community development principles and practices was significantly related to perceived effectiveness. The perceptions of effective healthcare promotion identified by partner organizations suggest that program and volunteer characteristics need to be carefully considered when deciding on methods of volunteer preparation and

The Convention on Early Notification of a Nuclear Accident (the 'Early Notification Convention') and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (the 'Assistance Convention') are prime legal instruments that establish an international framework to facilitate the exchange of information and the prompt provision of assistance in the event of a radiation emergency, with the aim of minimizing the consequences. The International Atomic Energy Agency (IAEA) has specific functions assigned to it under these Conventions, to which the the European Commission, through the European Atomic Energy Community (Euratom), the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO) and the World Meteorological Organization (WMO) are full Parties. The arrangements between the IAEA, States and international intergovernmental organizations ('international organizations') for facilitating the practical implementation of those articles of the two Conventions that are operational in nature are documented in the IAEA's Operations Manual for Incident and Emergency Communication (IEComm). In addition to the IEComm arrangements and pursuant to the obligations placed on the IAEA by the Conventions, the IAEA regularly convenes the Inter-Agency Committee on Radiological and Nuclear Emergencies (IACRNE), whose purpose is to coordinate the arrangements of the relevant international organizations for preparing for and responding to radiation incidents or emergencies. Although the Conventions assign specific response functions and responsibilities to the IAEA and the Parties, various international organizations have - by virtue of their statutory functions or of related legal instruments (including, for example, the WHO International Health Regulations 2005) - functions and responsibilities that encompass aspects of preparedness and response in this context.

Full Text Available This study employed 16S rRNA gene amplicon pyrosequencing to examine the hypothesis that chemolithotrophic Fe(II-oxidizing bacteria (FeOB would preferentially colonize the Fe(II-bearing mineral biotite compared to quartz sand when the minerals were incubated in situ within a subsurface redox transition zone (RTZ at the Hanford 300 Area site in Richland, WA, USA. The work was motivated by the recently documented presence of neutral-pH chemolithotrophic FeOB capable of oxidizing structural Fe(II in primary silicate and secondary phyllosilicate minerals in 300 Area sediments and groundwater (Benzine et al., 2013. Sterilized portions of sand+biotite or sand alone were incubated in situ for five months within a multilevel sampling (MLS apparatus that spanned a ca. 2-m interval across the RTZ in two separate groundwater wells. Parallel MLS measurements of aqueous geochemical species were performed prior to deployment of the minerals. Contrary to expectations, the 16S rRNA gene libraries showed no significant difference in microbial communities that colonized the sand+biotite versus sand-only deployments. Both mineral-associated and groundwater communities were dominated by heterotrophic taxa, with organisms from the Pseudomonaceae accounting for up to 70% of all reads from the colonized minerals. These results are consistent with previous results indicating the capacity for heterotrophic metabolism (including anaerobic metabolism below the RTZ as well as the predominance of heterotrophic taxa within 300 Area sediments and groundwater. Although heterotrophic organisms clearly dominated the colonized minerals, several putative lithotrophic (NH4+, H2, Fe(II, and HS- oxidizing taxa were detected in significant abundance above and within the RTZ. Such organisms may play a role in the coupling of anaerobic microbial metabolism to oxidative pathways with attendant impacts on elemental cycling and redox-sensitive contaminant behavior in the vicinity of the

The internal architecture of polymeric self-assembled chiral micro-particles is studied by exploring the effect of the chirality, of the particle sizes, and of the interface/surface properties in the ordering of the helicoidal planes. The experimental investigations, performed by means of different microscopy techniques, show that the polymeric beads, resulting from light induced polymerization of cholesteric liquid crystal droplets, preserve both the spherical shape and the internal self-organized structures. The method used to create the micro-particles with controlled internal chiral architectures presents great flexibility providing several advantages connected to the acquired optical and photonics capabilities and allowing to envisage novel strategies for the development of chiral colloidal systems and materials

International Organizations: the Main Factors of Emergence and Development

Directory of Open Access Journals (Sweden)

Lev S. Voronkov

2015-01-01

Full Text Available The author argues that the emergence of the first permanent intergovernmental (IIGO and non-governmental (INGO organizationsin the second half of the XIX-th century was due to common causes. He tries to justify the need to consider them not as independent objects of study, but as the phenomenon, caused by the high level of internationalization of economic life of states and of socio-economic consequences of the industrial revolution, reached in this period. The emergence of IIGOs, based on international treaty, was accompanied by establishment of a large number of INGOs operating in similar fields of human activity, which performed supplementary functions and regulated areas of cooperation and public needs, not covered by interstate agreements. The article presents the main factors that in later stages of internationalization and development of contemporary international relations gave the impetus to emergence and development of international organizations, including the military-technological revolution, that gave birth to mass destruction weapons and avalanche-like growth of the number of human and material losses during wars and military conflicts, the Cold War between world communism and world capitalism, the collapse of the colonial system and formation ofa new main contradiction of the world politics between the "Club of rich countries" and states of the "global periphery", beginning of development of regional integration processes and, finally, the emergence of global problems. The article emphasizes that both IIGOs and INGOs evolved from the supportive tools in implementation of multilateral interaction of sovereign states towards becoming an integral part of contemporary international relations, fulfilling many vital functions of modern human society and its citizens. Given the involvement of the overwhelming majority of modern sovereign states and tens of thousands of civil society organizations in activity of numerical IIGOs and INGOs

It is noted that long term programs aimed at optimizing schoolchildren nutrition have a beneficial effect on the children's health, culture of their nutrition and quality of life. The importance of carrying out similar programs in Russia is beyond any doubt: according to population research, the basic principles of good nutrition are often not observed, and school breakfasts and lunches do not correspond to the age physiological needs of children and teenagers for nutrient materials and energy. In this situation, the available experience of using vitaminbenriched products as well as vitamin and mineral complexes in children will permit to quickly resolve the existing problems of the improper, and sometimes, insufficient, nutrition.Key words: school nutrition, organization, international experience.

1999-01-01

Objective: To establish a new, simple and noninvasive method which can quantitatively analyze the colonic transit function by dual radionuclide colon scintigraphy. Methods: 24 patients with constipation and 32 normal controls were studied. Na 131 I was sealed into capsule made by polyvinylchloride which can not be digested and absorbed in gastrointestinal tract. Patients and normal volunteers swallow 131 I capsules and drink 99 Tc m labelled sulfur colloid solution at the same time. The static image was acquired at the regular time, then calculate the Geometric Center values (GC). Results: 1) The capsules can be clearly located through the colonic contour shown by 99 Tc m labeled sulfur colloid when it reached the large bowel. 2) The transiting time from mouth to cecum, through colon and through whole gastrointestinal in normal people were (6.61 +- 1.94), (36.61 +- 10.51) and (42.72 +- 10.02) h, respectively, in constipation group were (8.03 +- 3.63), (65.50 +- 28.40) and (74.05 +- 28.17) h, respectively. There was no significant difference (P > 0.05) in two groups compared with each other. But the transiting time through colon and whole gastrointestinal in constipation was slower than that in normal people, with significant difference (P < 0.01). 3) Through examination the colonic transit abnormality can be divided into three patterns: whole colon transit delay, right-colon transit delay and left-colon transit delay. Conclusions: This method is a simple, physiologic and quantitative in evaluating the colonic transit, it can also stage the colonic dyskinesia of the patients

International non-governmental organizations (NGOs) in official relation with the World Health Organization (WHO) face organizational challenges against the background of legitimate representation of their membership and accountable procedures within the organization. Moreover, challenges arise in the light of such an international NGO's civil societal mandate to help reach the "health-for-all" goals as defined by WHO and to facilitate the implementation of the United Nations (UN) Convention on the Rights of Persons with Disabilities. The objective of this paper is to examine how such an international NGO using the International Society of Physical and Rehabilitation Medicine (ISPRM) as a case in point can address these challenges. The specific aims are to analyse ISPRM's structures and procedures of internal organs and external relations and to develop solutions. These possible solutions will be presented as internal organizational scenarios and a yearly schedule of meetings closely aligned to that of WHO to facilitate an efficient internal and external interaction.

In the present work, we propose the first structural constitutive model of the passive mechanical behavior of the swine colon that is validated against physiological inflation-extension tests, and accounts for residual strains. Sections from the spiral colon and the descending colon were considered to investigate potential regional variability. We found that the proposed constitutive model accurately captures the passive inflation-extension behavior of both regions of the swine colon (coefficient of determination R 2 =0.94±0.02). The model revealed that the circumferential muscle layer does not provide significant mechanical support under passive conditions and the circumferential load is actually carried by the submucosa layer. The stress analysis permitted by the model showed that the colon tissue can distend up to 30% radially without significant increase in the wall stresses suggesting a highly compliant behavior of the tissue. This is in-line with the requirement for the tissue to easily accommodate variable quantities of fecal matter. The analysis also showed that the descending colon is significantly more compliant than the spiral colon, which is relevant to the storage function of the descending colon. Histological analysis showed that the swine colon possesses a four-layer structure similar to the human colon, where the longitudinal muscle layer is organized into bands called taeniae, a typical feature of the human colon. The model and the estimated parameters can be used in a Finite Element framework to conduct simulations with realistic geometry of the swine colon. The resulting computational model will provide a foundation for virtual assessment of safe and effective devices for the treatment of colonic diseases. Copyright © 2017 Elsevier Ltd.

Habitat selection by colonizing organisms is an important factor in determining species abundance and community dynamics at multiple spatial scales. Many organisms select habitat patches based on intrinsic patch quality, but patches exist in complex landscapes linked by dispersal and colonization, forming metapopulations and metacommunities. Perceived patch quality can be influenced by neighbouring patches through spatial contagion, wherein perceived quality of one patch can extend beyond its borders and either increase or decrease the colonization of neighbouring patches and localities. These spatially explicit colonization dynamics can result in habitat compression, wherein more colonists occupy a patch or locality than in the absence of spatial context dependence. Previous work on contagion/compression focused primarily on the role of predators in driving colonization patterns. Our goal was to determine whether resource abundance can drive multi-scale colonization dynamics of aquatic beetles through the processes of contagion and compression in naturally colonized experimental pools. We established two levels (high/low quality) of within-patch resource abundances (leaf litter) using an experimental landscape of mesocosms, and assayed colonization by 35 species of aquatic beetles. Patches were arranged in localities (sets of two patches), which consisted of a combination of two patch-level resource levels in a 2 × 2 factorial design, allowing us to assay colonization at both locality and patch levels. We demonstrate that patterns of species abundance and richness of colonizing aquatic beetles are determined by patch quality and context-dependent processes at multiple spatial scales. Localities that consisted of at least one high-quality patch were colonized at equivalent rates that were higher than localities containing only low-quality patches, displaying regional reward contagion. In localities that consisted of one high- and one low-quality patch, reward

Specific extracellular matrix remodeling signature of colon hepatic metastases.

Directory of Open Access Journals (Sweden)

Maguy Del Rio

Full Text Available To identify genes implicated in metastatic colonization of the liver in colorectal cancer, we collected pairs of primary tumors and hepatic metastases before chemotherapy in 13 patients. We compared mRNA expression in the pairs of patients to identify genes deregulated during metastatic evolution. We then validated the identified genes using data obtained by different groups. The 33-gene signature was able to classify 87% of hepatic metastases, 98% of primary tumors, 97% of normal colon mucosa, and 95% of normal liver tissues in six datasets obtained using five different microarray platforms. The identified genes are specific to colon cancer and hepatic metastases since other metastatic locations and hepatic metastases originating from breast cancer were not classified by the signature. Gene Ontology term analysis showed that 50% of the genes are implicated in extracellular matrix remodeling, and more precisely in cell adhesion, extracellular matrix organization and angiogenesis. Because of the high efficiency of the signature to classify colon hepatic metastases, the identified genes represent promising targets to develop new therapies that will specifically affect hepatic metastasis microenvironment.

A 64 year-old woman presented with advanced, transverse colon cancer arising in the diverticulum. Tumor invasion extended beyond the serosa to the anal side of the colon. Anemia and fatigue progressed after 6 months of iron administration. The hemoglobin value was 5.3 g/dL and carcinoembryonic antigen (CEA) level was elevated to 44.2 ng/mL. A palpable and tender fist-sized mass was found in the right upper abdomen. Computed tomography (CT) revealed a low-density mass in the transverse colon invading beyond the serosa to the anal side of the colon. Right hemi-colectomy with lymph node dissection was performed. The resected specimen contained multiple diverticula including the one from which the tumor arose. Histological examination revealed a well-differentiated, tubular adenocarcinoma (UICC TNM T4bN0M0) arising in a transverse colon diverticulum. There has been no recurrence for 2 years. Colon cancer arising in a diverticulum may expand to the extra-serosa and easily invade to the adjacent organ. In such cases, malignancy should be considered.

Colonic spirochetosis in animals and humans.

Science.gov (United States)

Smith, James L

2005-07-01

Colonic spirochetosis is a disease caused by the gram-negative bacteria Brachyspira aalborgi and Brachyspira pilosicoli. B. pilosicoli induces disease in both humans and animals, whereas B. aalborgi affects only humans and higher primates. Symptoms in humans include diarrhea, rectal bleeding, and abdominal cramps. Colonic spirochetosis is common in third world countries; however, in developed countries, the disease is observed mainly in homosexual males. Terminally ill patients infected with Brachyspira are particularly at risk for developing spirochetemia. Diarrhea, poor growth performance, and decreased feed-to-gain efficiency is seen in pigs with colonic spirochetosis. The disease in chickens is characterized by delayed and/or reduced egg production, diarrhea, poor feed conversion, and retarded growth. Thus, colonic spirochetosis can represent a serious economic loss in the swine and poultry industries. The organisms are transmitted by the fecal-oral route, and several studies have demonstrated that human, primate, pig, dog, or bird strains of B. pilosicoli can be transmitted to pigs, chickens, and mice. B. pilosicoli may be a zoonotic pathogen, and although it has not been demonstrated, there is a possibility that both B. pilosicoli and B. aalborgi can be transferred to humans via contact with the feces of infected animals, meat from infected animals, or food contaminated by food handlers. Neither B. pilosicoli nor B. aalborgi has been well characterized in terms of basic cellular functions, pathogenicity, or genetics. Studies are needed to more thoroughly understand these Brachyspira species and their disease mechanisms.

The gastrointestinal (GI) tract is unique compared to all other internal organs; it is the only organ with its own nervous system and its own population of intrinsic sensory neurons, known as intrinsic primary afferent neurons (IPANs). How these IPANs form neuronal circuits with other functional classes of neurons in the enteric nervous system (ENS) is incompletely understood. We used a combination of light microscopy, immunohistochemistry and confocal microscopy to examine the topographical distribution of specific classes of neurons in the myenteric plexus of guinea-pig colon, including putative IPANs, with other classes of enteric neurons. These findings were based on immunoreactivity to the neuronal markers, calbindin, calretinin and nitric oxide synthase. We then correlated the varicose outputs formed by putative IPANs with subclasses of excitatory interneurons and motor neurons. We revealed that calbindin-immunoreactive varicosities form specialized structures resembling 'baskets' within the majority of myenteric ganglia, which were arranged in clusters around calretinin-immunoreactive neurons. These calbindin baskets directly arose from projections of putative IPANs and represent morphological evidence of preferential input from sensory neurons directly to a select group of calretinin neurons. Our findings uncovered that these neurons are likely to be ascending excitatory interneurons and excitatory motor neurons. Our study reveals for the first time in the colon, a novel enteric neural circuit, whereby calbindin-immunoreactive putative sensory neurons form specialized varicose structures that likely direct synaptic outputs to excitatory interneurons and motor neurons. This circuit likely forms the basis of polarized neuronal pathways underlying motility. © 2018 Wiley Periodicals, Inc.

2015-01-01

To compare cutaneous and nasal population levels between patients colonized and infected by multidrug-resistant organisms in two intensive care units. A prospective cohort study was performed in adult intensive care units of two hospitals in Belo Horizonte, Brazil (April 2012 to February 2013). Clinical and demographic data were first collected by reviewing patients' charts. Then, samples collected with nasal, groin, and perineum swabs were cultivated in selective media for 48 h at 37°C. After isolation, determination of antimicrobial susceptibility and biochemical identification were performed. A total of 53 cases of colonization were observed by the following bacteria in decreasing frequencies: imipenem-resistant Acinetobacter baumannii (50.9%), vancomycin-resistant Enterococcus faecalis (43.4%), extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (37.7%), imipenem-resistant Pseudomonas aeruginosa (32.1%), oxacillin-resistant Staphylococcus aureus (7.5%), and imipenem-resistant Klebsiella pneumoniae (5.7%). Among these colonization cases, 26 (49.0%) were followed by infection with bacteria phenotypically similar to those of the colonization. A relation between high population levels of colonization by most of the multidrug-resistant organisms at anatomical sites and a subsequent infection was observed. After colonization/infection, bacterial population levels decreased progressively and spontaneously until disappearance by day 45 in all the anatomical sites and for all the multidrug-resistant organisms. There was a correlation between high population levels of colonization by multidrug-resistant organisms at anatomical sites and a subsequent infection. Reduction in multidrug-resistant organism populations after colonization at anatomical sites could be a preventive measure to reduce evolution to infection as well as transmission of these bacteria between patients in intensive care unit.

Primary cancer may occur synchronously in two different organs. We present an example of pathologically proven, coexistent renal and colony double malignant tumors. A 59 year old man, was admitted to the Institute of Oncology due to left renal lesion, discovered during a routine abdominal ultrasound examination. The CT exam was performed before surgery. The CT scans reveled a second abnormality, presenting irregular shaped and thickened to 20 mm intestinal wall within a patient's large bowel. As a next diagnostic step a CT-colonoscopy was undertaken, which confirmed the presence of an exophytic sigmoid lesion, eccentrically affecting the colonic wall and protruding into the lumen moderately narrowing it, placed about 50 cm from the external rectal sphincter. Patient underwent simultaneous radical left nephrectomy and sigmoidectomy. Both tumors were confirmed in pathologic evaluation, reveling renal clear cell carcinoma (Fuhrman G II) and colonic adenocarcinoma (Astler-Coller B2). Preoperative careful imaging studies reveled neoplastic tumors in two different organs, allowing for radical resection at the same surgical procedure. (author)

Full Text Available Background. Colon capsule endoscopy (CCE is a diagnostic test with relatively rare usage. In this study, we aimed to evaluate both the optimal cleaning regimen for CCE and the diagnostic value of test in the study group. Methods. A total of 62 patients were enrolled in this study. In the first step, 3 different colon preparing regimens were given to 30 patients [Group A: 3 days of liquid diet, sodium phosphate (NaP (90 mL, and NaP enema; Group B: 3 days of liquid diet, 4 L of polyethylene glycol (PEG, and metoclopramide; Group C: 3 days of liquid diet, 4 L of PEG, NaP (45 mL, and bisacodyl after capsule ingestion] (10 patients in each group. The other consecutive 32 patients were cleaned with the best regimen which was NaP + PEG and CCE was performed. The results of CCE were controlled with colonoscopy in 28 patients. Results. Group C had the highest cleaning score, compared with the other groups (2.2±0.4 versus 2.7±0.4 versus 3.7±0.4, p value =0.000. The CCE findings were as follows in 28 patients who were also examined with colonoscopy: polyp (range: 5–10 mm in 6 patients, internal hemorrhoids in 3 patients, angiodysplasia in 1 patient, diverticula in 1 patient, and ulcerative colitis in 1 patient. The sensitivity, specificity, PPV, and NPV of CCE were 100%, 92%, 93%, and 100%, respectively. Conclusions. Low dosage NaP combined with PEG provides optimal bowel preparation for CCE. CCE appears to be a highly sensitive diagnostic modality for detecting colonic pathologies.

Colorectal cancer is one of the most common cancers and the third leading cause of cancer death in both sexes. The disease progresses as a multistep process and is associated with genetic alterations. One of the characteristic features of cancer is telomerase activation. We sought to evaluate the differences in telomerase activity between colon cancer and adjacent normal tissue and to correlate the differences in telomerase activity between different locations with clinicopathological factors and survival. Matched colon tumour samples and adjacent normal mucosa samples 10 cm away from the tumour were collected during colectomy. We assessed telomerase activity using real time polymerase chain reaction. Several pathological characteristics of tumours, including p53, Ki-67, p21, bcl2 and MLH1 expression were also studied. We collected samples from 49 patients. There was a significantly higher telomerase activity in colon cancer tissue than normal tissue. Adenocarcinomas of the right colon express significantly higher telomerase than left-side cancers. Colon cancers and their adjacent normal tissue had significantly more telomerase and were more positive to MLH1 than rectal cancers. The expression of p53 negatively correlated to telomerase activity and was linked to better patient survival. Colon and rectal cancers seem to have different telomerase and MLH1 profiles, and this could be another factor for their different biologic and clinical behaviour and progression. These results support the idea that the large bowel cannot be considered a uniform organ, at least in the biology of cancer.

Experience with nuclear safety standards development in non-governmental international organizations

International Nuclear Information System (INIS)

Becker, K.

1985-01-01

Besides the IAEA as a 'governmental' organization dealing with basic safety recommendations addressed primarily to the national regulatory bodies in developing countries, two closely related non-governmental international standards organizations have gained extensive experience in the field of nuclear standardization. Over more than 25 years since their formation, both (a) the International Organization for Standardization's (ISO) Technical Committee 85 'Nuclear Energy', in particular in its Sub-Committee 3 'Reactor Technology and Safety' and (b) the International Electrotechnical Commission's (IEC) Technical Committee 45 'Nuclear Instrumentation' have published numerous standards. A brief review is given of these, draft standards, and other documents planned to become international standards. Many of them deal with rather specialized topics typical for 'industrial' standards such as standardized procedures, instruments, methods, materials, test methods, terminology, and signs and symbols, but others are directly related to more basic safety issues. In some areas such as quality assurance, seismic aspects of siting and terminology, there has been in the past occasional overlap in the activities of the NUSS programme, IEC and ISO. Letters of Understanding have since 1981 contributed to clarifying the borderlines and to avoiding redundant efforts. Also, some experiences and problems are described arising, for example, from the harmonization of different national safety philosophies and traditions into universally accepted international standards, and the transfer of international standards into national standards systems. Finally, based on a recent comprehensive compilation of some 3300 nuclear standards and standards projects, an attempt is made to present a cost/benefit analysis and an outlook on future developments.

CT pictures from 59 lesions of advanced colon cancer including rectal cancer were reviewed to evaluate a role of CT in preoperative staging diagnosis. CT findings were recorded following general rules for clinical and pathological studies on cancer of colon rectum and anus, proposed by Japanese society for cancer of colon and rectum. Tumors were detected in 90% of advanced colon cancers. Sensitivity in local extension (S factor) was 58.0%. Sensitivity in lymphonode involvement (N factor) was 50.0%. Sensitivity in final staging diagnosis, dividing colon cancer into two groups below st II and above st III, was 63.3%. Further study should be necessitated to provide useful information for preoperative staging diagnosis of colon cancer. (author)

The state of the international organ trade: a provisional picture based on integration of available information.

Science.gov (United States)

Shimazono, Yosuke

2007-12-01

Organ transplantation is widely practised worldwide. The expansion of organ transplantation has led to a critical shortage of organs and the development of the organ trade. Many patients travel to areas where organs are obtainable through commercial transactions. Although the international organ trade is regarded as an important health policy issue, its current state remains obscure because of scarce data and the lack of efforts to synthesize available data. This paper is an attempt to integrate information about the current international organ trade and create a tentative global picture based on a systematic review of 309 media reports, journal articles and other documents. The international organ trade is described in terms of its forms, the organ-exporting countries, the organ-importing countries and its outcomes and consequences.

Russia’s 2015 BRICS Presidency: Models of Engagement with International Organizations

Directory of Open Access Journals (Sweden)

Marina Larionova

2016-09-01

Full Text Available Six years after the first 2009 summit in Yekaterinburg, the BRICS grouping of Brazil, Russia, India, China and South Africa has established its identity as an informal global governance forum. The members have consistently consolidated their cooperation, expanded and deepened their agenda, coordinated efforts aimed at the recovery and growth of their economies, and engaged with other international organizations. This work continued during the Russian presidency in 2015. This article focuses on one dimension of BRICS performance: its engagement with international organizations. Atleast three reasons define the relevance of this analysis. First, since its launch the BRICS members collectively committed tobuilding a multipolar, fair and democratic world order, which would not be possible without cooperating with key international organizations. Second, the objective of enhancing the sustainability, legitimacy and effectiveness of the global governance architecture defines the need for the flexible combination of different models of engagement of summit institutions with other international institutions. Third, according to Russia’s BRICS Presidency Concept, one of its priorities was to transition to a qualitatively new level of engagement with international organizations.The analytical framework for this study thus builds on the theory of rational choice institutionalism. The calculus approach fits the analysis of summit institutions bringing together states from a wide range of cultures, continents and economic development. Its distinctive features clearly apply to the analysis of the origin and performance of the BRICS. First, members act in a highly strategic manner to attain their priorities. Second, summitry presents an arrangement where strategic interaction among leaders plays a major role in determining political outcomes. Third, rational choice institutionalism offers the greatest analytical leverage to settings where consensus among

Epithelial organs adjust the „inner milieu“ of the body and are crucial for all homeostatic processes. Epithelial transport of different solutes and water is regulated phenomena. The regulation processes include both long term hormonal regulation and short term local agonist mediated regulation....... This research project is the summary of 3 original papers addressing the functional role of different regulating factors on ion transport in mouse distal colon. The first paper addresses the effect of luminal nucleotides on electrogenic Na+ absorption. The distal colon, like the distal nephron is an aldosterone......-sensitive tissue and participates in the regulation of Na+ excretion. In the distal nephron it was found that luminal nucleotides inhibit ENaC-mediated Na+ absorption. Here it was addressed whether luminal nucleotides regulate Na+ absorption and if so, which of the known luminal P2 receptors are involved. Using...

In an attempt to overcome infections associated with central venous catheters, a new antiseptic central venous catheter coated with benzalkonium chloride on the internal and external surfaces has been developed and evaluated in a clinical trial. Patients (235) randomly received either a triple-lumen central venous catheter coated with benzalkonium chloride (117) or a polyurethane non-antiseptic catheter (118). The incidence of microbial colonization of both catheters and retained antiseptic activity of the benzalkonium chloride device following removal were determined. The benzalkonium chloride resulted in a significant reduction of the incidence of microbial colonization on both the internal and external catheter surfaces. The reduction in colonization was detected at both the intradermal (21 benzalkonium chloride catheters vs. 38 controls, P = 0.0016) and distal segments of the antiseptic-coated catheters. Following catheter removal retained activity was demonstrated in benzalkonium chloride catheters which had been in place for up to 12 days. No patients developed adverse reactions to the benzalkonium chloride catheters. The findings demonstrate that the benzalkonium chloride catheter significantly reduced the incidence of catheter-associated colonization.

2017-02-01

Some researchers suggest that cancers located in the right vs. the left side of the colon are different and they can be regarded as distinct disease entities. The aim of this study was to analyze differences in clinical, epidemiological and pathological features of patients with right-sided (RCC) and left-sided (LCC) colon cancer. One thousand two hundred and twenty-four patients were operated on due to colorectal cancer. A group of 477 patients (254 women, mean age 65.5 ±11 for the whole group) with colon cancer was included (212 RCC vs. 265 LCC). Right colon cancer patients were older (67.8 ±11.3 vs. 63.2 ±11.2; p = 0.0087). Left colon cancer patients underwent surgery for urgent indications more often (17.0% vs. 8.5%; p = 0006). Tumor diameter was greater in the RCC group (55 ±60 mm vs. 38 ±21 mm; p = 0.0003). Total number of removed lymph nodes was higher in the RCC group (11.7 ±6 vs. 8.3 ±5; p = 0.0001). Lymph node ratio was higher in the LCC group (0.45 ±0.28 vs. 0.30 ±0.25; p = 0.0063). We found a strong positive correlation between tumor diameter and the number of removed lymph nodes in the LCC group ( r = 0.531). These differences may result from the fact that RCC patients are diagnosed at an older age. The smaller number of removed lymph nodes in LCC patients may result in incorrect staging. It is still necessary to find other biological dissimilarities of adenocarcinoma located on different sides of the colon.

Neofusicoccum parvum Colonization of the Grapevine Woody Stem Triggers Asynchronous Host Responses at the Site of Infection and in the Leaves

Directory of Open Access Journals (Sweden)

Mélanie Massonnet

2017-06-01

Full Text Available Grapevine trunk diseases cause important economic losses in vineyards worldwide. Neofusicoccum parvum, one of the most aggressive causal agents of the trunk disease Botryosphaeria dieback, colonizes cells and tissues of the grapevine wood, leading to the formation of an internal canker. Symptoms then extend to distal shoots, with wilting of leaves and bud mortality. Our aim was to characterize the transcriptional dynamics of grapevine genes in the woody stem and in the leaves during Neofusicoccum parvum colonization. Genome-wide transcriptional profiling at seven distinct time points (0, 3, and 24 hours; 2, 6, 8, and 12 weeks showed that both stems and leaves undergo extensive transcriptomic reprogramming in response to infection of the stem. While most intense transcriptional responses were detected in the stems at 24 hours, strong responses were not detected in the leaves until the next sampling point at 2 weeks post-inoculation. Network co-expression analysis identified modules of co-expressed genes common to both organs and showed most of these genes were asynchronously modulated. The temporal shift between stem vs. leaf responses affected transcriptional modulation of genes involved in both signal perception and transduction, as well as downstream biological processes, including oxidative stress, cell wall rearrangement and cell death. Promoter analysis of the genes asynchronously modulated in stem and leaves during N. parvum colonization suggests that the temporal shift of transcriptional reprogramming between the two organs might be due to asynchronous co-regulation by common transcriptional regulators. Topology analysis of stem and leaf co-expression networks pointed to specific transcription factor-encoding genes, including WRKY and MYB, which may be associated with the observed transcriptional responses in the two organs.

Colonic diverticulosis may represent a risk factor for colonic adenomas by virtue of the fact that evolving data suggest that these 2 conditions may share common risk factors such as Western dietary pattern and physical inactivity. This study aims to investigate the association between colonic diverticulosis and colonic adenomas in mainland China. We conducted a cross-sectional study on patients who underwent colonoscopic examination between October 2013 and December 2014 in a university hospital in mainland China. Age, gender, colonic adenomas, advanced adenomas, and distribution of diverticulosis were recorded during the procedures. Multivariate logistic regression and stratified analysis were used to evaluate the associations between the prevalence of diverticulosis and age, sex, and presence of colonic adenomas and advanced adenomas. A total of 17,456 subjects were enrolled. The prevalence of colonic diverticulosis and adenoma was 2.4% and 13.2%, respectively. With regard to distribution of diverticula, most (365/424, 86.1%) were right-sided. Multiple logistic regression analysis suggested that age and male gender were independent risk factors for adenoma and advanced adenoma. There was no relationship between diverticulosis or location of diverticulosis and presence of adenoma and advanced adenoma adjusting by age and gender. In a stratified analysis according to age and gender, similar results were also noted. There was no statistical relationship between diverticulosis and the risk of adenoma and advanced adenoma. Our results may not be generalized to the Western population due to the fact that left-sided diverticular cases were very small in our study.

Cytomegalovirus (CMV) infection causes significant morbidty and mortality in immunopromised patients. Though it is usually silent in immunocompetent adults, rarely it can cause serious life-threatening complications. Gastrointestinal tract is one of the commonly involved organs, where it produces a spectrum of clinical manifestation ranging from mild non-specific abdominal pain and diarrhoea to severe infection with toxic megacolon and death. We present a 65-year-old immunocompetent male patient admitted with acute colonic obstruction secondary to CMV-induced colonic stricture, highlighting the importance of considering it as a differential diagnosis for colonic obstruction and reviewing its management.

Arbuscular mycorrhizal fungi (AMF) can affect insect herbivores by changing plant growth and chemistry. However, many factors can influence the symbiotic relationship between plant and fungus, potentially obscuring experimental treatments and ecosystem impacts. In a field experiment, we assessed AMF colonization levels of individual ragwort ( Senecio jacobaea) plants growing in grassland plots that were originally sown with 15 or 4 plant species, or were unsown. We measured the concentrations of carbon, nitrogen and pyrrolizidine alkaloids (PAs), and assessed the presence of aboveground insect herbivores on the sampled plants. Total AMF colonization and colonization by arbuscules was lower in plots sown with 15 species than in plots sown with 4 species and unsown plots. AMF colonization was positively related to the cover of oxeye daisy ( Leucanthemum vulgare) and a positive relationship between colonization by arbuscules and the occurrence of a specialist seed-feeding fly ( Pegohylemyia seneciella) was found. The occurrence of stem-boring, leaf-mining and sap-sucking insects was not affected by AMF colonization. Total PA concentrations were negatively related to colonization levels by vesicles, but did not differ among the sowing treatments. No single factor explained the observed differences in AMF colonization among the sowing treatments or insect herbivore occurrence on S. jacobaea. However, correlations across the treatments suggest that some of the variation was due to the abundance of one plant species, which is known to stimulate AMF colonization of neighbouring plants, while AMF colonization was related to the occurrence of a specialist insect herbivore. Our results thus illustrate that in natural systems, the ecosystem impact of AMF through their influence on the occurrence of specialist insects can be recognised, but they also highlight the confounding effect of neighbouring plant species identity. Hence, our results emphasise the importance of field

Stage III colon cancer is currently treated as an entity with a unified therapeutic principle. The aim of the retrospective study is to explore the clinicopathological characteristics and outcomes of site-specific stage III colon cancers and the influences of tumor location on prognosis. Eight hundred ninety-five patients with stage III colon cancer treated with radical operation and subsequent adjuvant chemotherapy (5-fluorouracil/oxaliplatin) were divided into seven groups according to colon segment (cecum, ascending colon, hepatic flexure, transverse colon, splenic flexure, descending colon, and sigmoid colon). Expression of excision repair cross-complementing group 1 (ERCC1) and thymidylate synthase (TS) was examined by immunohistochemistry. We assessed if differences exist in patient characteristics and clinic outcomes between the seven groups. There were significant differences in tumor differentiation (P Cancer (AJCC) tumor-node-metastasis (TNM) stage (P colon. Cox regression analyses identified that tumor location was an independent prognostic factor for RFS and OS. Stage III colon cancer located proximally carried a poorer survival than that located distally. Different efficacies of FOLFOX adjuvant chemotherapy may be an important factor affecting survival of site-specific stage III colon cancers.

In this paper, we present a simple spring-block model for ocean internal waves based on the self-organized criticality (SOC). The oscillations of the water blocks in the model display power-law behavior with an exponent of -2 in the frequency domain, which is similar to the current and sea water temperature spectra in the actual ocean and the universal Garrett and Munk deep ocean internal wave model [Geophysical Fluid Dynamics 2 (1972) 225; J. Geophys. Res. 80 (1975) 291]. The influence of the ratio of the driving force to the spring coefficient to SOC behaviors in the model is also discussed. (general)

To study how microbes establish themselves in a mammalian gut environment, we colonized germ-free mice with microbial communities from human, zebrafish, and termite guts, human skin and tongue, soil, and estuarine microbial mats. Bacteria from these foreign environments colonized and persisted in the mouse gut; their capacity to metabolize dietary and host carbohydrates and bile acids correlated with colonization success. Cohousing mice harboring these xenomicrobiota or a mouse cecal microbiota, along with germ-free "bystanders," revealed the success of particular bacterial taxa in invading guts with established communities and empty gut habitats. Unanticipated patterns of ecological succession were observed; for example, a soil-derived bacterium dominated even in the presence of bacteria from other gut communities (zebrafish and termite), and human-derived bacteria colonized germ-free bystander mice before mouse-derived organisms. This approach can be generalized to address a variety of mechanistic questions about succession, including succession in the context of microbiota-directed therapeutics.

The antimicrobial effect of 20 minutes exposure to 10% povidone-iodine solution and to 5% neomycin-erythromycin solution was evaluated in vitro in 6 suspensions of dog feces. Povidone-iodine eliminated aerobic growth (P less than 0.001) and reduced anaerobes 4.01 +/- 1.06 (P less than 0.02); C. perfringens was the only anaerobic organism grown. Forty unprepared dogs underwent resection of the sigmoid colon and primary anastomosis. Twenty received normal saline and 20 povidone-iodine injected intraluminally immediately before resection. The colon contents of povidone-iodine treated dogs grew only 0.07 +/- 0.07 aerobes and 3.74 +/- 0.49 anaerobes (all Clostridia) (log10/ml colon contents) (P less than 0.001). All povidone-iodine dogs survived 3 weeks with no anastomotic leaks; three controls died from anastomotic leak within the first week (P = 0.12). Reexploration of survivors revealed less perianastomotic reaction in the povidone-iodine group. Twenty minutes exposure to povidone-iodine produced a significant decrease in bacterial counts in vitro and in unprepared sigmoid colon. No adverse effects were demonstrated. Images Fig. 4.

1983-02-01

Trichosporon beigelii and Trichosporon capitatum have recently been recognized as systemic pathogens in the immunosuppressed host. We studied the incidence of colonization and systemic infection with these organisms in 353 highly immunocompromised patients over a 37-month period. Thirteen patients (3.7%) had positive surveillance cultures for Trichosporon species in stool, skin, or urine. Three of the 13 patients developed systemic infections after having positive surveillance cultures. In two of these three patients, urine cultures were positive near the time of systemic infection. The route of entry appeared to have been enteric in two patients and cutaneous in one patient. Both colonizing and infecting organisms showed in vitro susceptibility to amphotericin B and nystatin. This study suggests that positive surveillance cultures for Trichosporon species may correlate with systemic infection in the severely immunocompromised patient and that repeated positive urine cultures may indicate dissemination.

Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002. Materials and methods: From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study. Results: Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine. Conclusion: The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilatation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours [it

30 years have passed since Conference of Experts on the Rational Use of Drugs was held in Nairobi, Kenya, from 25 to 29 November 1985, where the problem of counterfeit medicines was mentioned as the international for the first time. The problem of counterfeit medicines is not only a major threat to public health and national and private economy, but also it is of great interest for key decision-making actors at the international level. The authors analyzed what has been done since that time by international organizations. Combating the counterfeiting of medicines cannot be successfully achieved by the health sector alone - World Health Organization (WHO), - so the efforts of the other United Nations (UN) organizations relevant to counterfeiting were in need and were studied in the article: World Intellectual Property Organization (WIPO), World Trade Organization (WTO), World Customs Organization (WCO), United Nations Office on Drugs and Crime (UNODC), etc. Today WHO is unable to coordinate all their activities, so the few existing proposals for establishing a new mechanism of international cooperation have been examined. Will the MEDICRIME Convention that will enter into force on January 1, 2016 be the start of the new era in the combating with the counterfeit medicines? - the authors offered their vision on the international developments.

Colonic volvulus is a common cause of large bowel obstruction worldwide. It can affect all parts of the colon, but most commonly occurs in the sigmoid and cecal areas. This disease has been described for centuries, and was studied by Hippocrates himself. Currently, colonic volvulus is the third most common cause of large bowel obstruction worldwide, and is responsible for ∼15% of large bowel obstructions in the United States. This article will discuss the history of colonic volvulus, and the predisposing factors that lead to this disease. Moreover, the epidemiology and diagnosis of each type of colonic volvulus, along with the various treatment options will be reviewed. PMID:24294126

Full Text Available In the present article characteristics and patterns of the impact of the international financial and economic organizations on the development of Russian law in the present-day conditions are described. It is noted, that the international financial and economic organizations firmly rooted in the world. They are based on international agreements, which participants could be also non-State structures. The role of international financial and economic organizations in the development of the negative effects of globalization and the production of global financial crisis is considered. The necessity to change the economic course of our country was proved because of the crisis and sanctions, as well as the need to find new ways of structuring the international financial and economic space, including the basis of the new inter-state unions and a new reserve currency. It is shown that the Russian domestic law should be the barrier against the destabilizing influence of transnational corporations. Legal acts of the Russian Federation defining the terms and scope of cooperation with international economic and financial organizations were analyzed. It is noted, that in accordance with applicable Russian legislation, international financial institutions have the right to invest in Russian companies, including and strategic. It is proved that the situation in the modern world and its negative manifestations determine the need for a number of effective measures and require changes in legislation. It is necessary to make changes in the current Russian legislation, first of all, investment, banking, trade, etc., to develop effective legal mechanisms for the protection of domestic producers and the national market from the expansion of multinational corporations.

This paper aimed at developing the strategy for facilitating the Korean participation as a higher staff in the nuclear related international organizations. - For that purpose, this Study focused on the following three subjects ; (1) to analyze the job situation of international organizations, (2) to analyze the background information and the procedure of appointment, (3) to suggest a facilitating strategy. - There are over 40 higher staff members including Director-General, six Deputy Director-General and 36 Directors in IAEA. Analysis shows that there are three main factors which influence the appointment of those higher position; geographical distribution, members' contributions towards the regular budget and a nation's influencing power to the international community. We can categorize into two case in aspect of the agency's appointment procedure. A director's position is generally decided through the open competition. In the case of Deputy Director-General or higher position, however, it is a practice that the Agency appoints the candidates through a unofficial procedure considering political situation. - There are twelve higher staffs in NEA. Influencing power and members' contributions towards the regular budget are the major criteria of higher staff's appointment. - It is expected that this study will contribute to the facilitation of Korean participation as a higher staff in the international organization by supplying the basic strategy.

Although colonic diverticulitis has no indication for operation, but in some mistaken cases were operated with a diagnosis of acute appendicitis. We evaluated the CT findings of colonic diverticulitis about 19 cases and of asymptomatic colonic diverticula about 15 cases retrospectively. Diagnosis was confirmed of barium enema and operation. CT are complementary methods of examination that can delineated the range of thickening of the colon and the extension of inflammatory changes around the colon. We also believe that CT findings of colonic diverticulitis are useful for differentiating from a diagnosis of appendicitis. (author)

Microbial pathways in colonic sulfur metabolism and links with health and disease

Directory of Open Access Journals (Sweden)

Franck eCarbonero

2012-11-01

Full Text Available Sulfur is both crucial to life and a potential threat to health. While colonic sulfur metabolism mediated by eukaryotic cells is relatively well studied, much less is known about sulfur metabolism within gastrointestinal microbes. Sulfated compounds in the colon are either of inorganic (e.g., sulfates, sulfites or organic (e.g., dietary amino acids and host mucins origin. The most extensively studied of the microbes involved in colonic sulfur metabolism are the sulfate-reducing bacteria, which are common colonic inhabitants. Many other microbial pathways are likely to shape colonic sulfur metabolism as well as the composition and availability of sulfated compounds, and these interactions need to be examined in more detail. Hydrogen sulfide is the sulfur derivative that has attracted the most attention in the context of colonic health, and the extent to which it is detrimental or beneficial remains in debate. Several lines of evidence point to sulfate-reducing bacteria or exogenous hydrogen sulfide as potential players in the etiology of intestinal disorders, inflammatory bowel diseases and colorectal cancer in particular. Generation of hydrogen sulfide via pathways other than dissimilatory sulfate reduction may be as, or more, important than those involving the sulfate-reducing bacteria. We suggest here that a novel axis of research is to assess the effects of hydrogen sulfide in shaping colonic microbiome structure. Clearly, in-depth characterization of the microbial pathways involved in colonic sulfur metabolism is necessary for a better understanding of its contribution to colonic disorders and development of therapeutic strategies.

Using the International Society of Physical and Rehabilitation Medicine (ISPRM) as a case in point, the paper describes the complex world societal situation within which non-governmental organizations that address health issues have to operate.This paper describes the complex world societal situation within which non-governmental organizations (NGOs), that are addressing health issues have to operate. In particular, as an international organization in official relation with the World Health Organization (WHO), ISPRM is confronted with a variety of responsibilities and a true world health political mandate. The accompanying rights need to be played out in relation to its own internal member organization and external allies. The theory of the world society and the current situation are briefly reviewed. The role of international NGOs within the world health polity, rehabilitation and Physical and Rehabilitation Medicine (PRM) is highlighted, whilst special emphasis is placed on NGOs in official relation with WHO. Functions, dysfunctions and challenges of international NGOs operating in the health sector are discussed. Against this background, key approaches to enhance ISPRM's political role are analysed. These include transparent and accountable development of the organization, the differentiation between internal and external policy relations, the harmonization of organizational structures and procedures, the consequential use of political structures available to influence WHO's agenda, and the identification of other policy players of major relevance to PRM in order to build strategic alliances with external partners and to enhance ISPRM's membership base.

Fournier gangrene (FG) is an infectious condition with fulminant evolution and is sometimes life-threatening. Here, we present the case of an immunocompromised 59-year-old male with surgical history of a pancreatic pseudocyst stented endoscopically. After unrecognized stent migration in the sigmoid without colonic perforation, he developed severe necrosis of the scrotum and perineum, which spontaneously perforated, presenting a smell suggesting moist gangrene. FG that has spread to the male genital organs presents therapeutic challenges. The purpose of our study is to present this case, typical for FG, with an educational aim both for the internal and surgical specialties, and the goal of further multidisciplinary collaboration for the optimal management of the patient with personalized treatment.

To evaluate ultrasonographic (US) findings of right-side colonic diverticulitis and to correlate them with pathologic findings. Twenty nine patients with surgically (n=7) and radiographically (n=8) proven diverticulitis in the cecum and ascending colon for the past five years were included in this study, and they all underwent US due to right lower quadrant abdominal pain. US findings were analyzed by two radiologists with a special emphasis on: (1) the presence, size, and internal echo of hypoechoic lesion bulging out from the colonic wall (thickened diverticulum), (2) changes in the adjacent cecum and ascending colon, (3) changes in the adjacent mesentery, (4) accompanying fluid collection, and (5) the presence of lymphadenopathy. US finding of 18 surgically proven patients were correlated with pathologic findings. On US, 25 of 29 patients (86.2%0 were found to have thicken diverticulum with the greater dimension of 8-20 mm (mean,, 12 mm). Wall thickening of the adjacent cecum and ascending colon was seen in 28 patients (96.5%), and 22 (75.9%) of them had eccentrically thickened wall. Comparing US findings with pathologic findings in 18 surgically proven patients, all revealed to have inflamed diverticulum on surgery, but only 15 showed thickened diverticulum on US. In 12 patients, fecalith, purulent exudates, and hemorrhage were found within diverticulum on surgery. In case of diverticulitis containing fecalith, all of their echogenecities were increased. All patients showed wall thickening of the adjacent colon and increased echogenecity of the adjacent mesentery on US. Pathologic findings of these thickened walls contained nonspecific inflammatory change and hemorrhage while the mesentery with an increased echogenecity contained purulent or hemorrhagic exudates. Ultrasonography can diagnose the right-side colonic diverticulitis when there is the presence of thickened diverticulum in the area with the thickened right side colonic wall in patients with right

Maternal rectovaginal colonization with group B Streptococcus (GBS) is the most common pathway for GBS disease in mother, fetus, and newborn. This article, the second in a series estimating the burden of GBS, aims to determine the prevalence and serotype distribution of GBS colonizing pregnant women worldwide. We conducted systematic literature reviews (PubMed/Medline, Embase, Latin American and Caribbean Health Sciences Literature [LILACS], World Health Organization Library Information System [WHOLIS], and Scopus), organized Chinese language searches, and sought unpublished data from investigator groups. We applied broad inclusion criteria to maximize data inputs, particularly from low- and middle-income contexts, and then applied new meta-analyses to adjust for studies with less-sensitive sampling and laboratory techniques. We undertook meta-analyses to derive pooled estimates of maternal GBS colonization prevalence at national and regional levels. The dataset regarding colonization included 390 articles, 85 countries, and a total of 299924 pregnant women. Our adjusted estimate for maternal GBS colonization worldwide was 18% (95% confidence interval [CI], 17%-19%), with regional variation (11%-35%), and lower prevalence in Southern Asia (12.5% [95% CI, 10%-15%]) and Eastern Asia (11% [95% CI, 10%-12%]). Bacterial serotypes I-V account for 98% of identified colonizing GBS isolates worldwide. Serotype III, associated with invasive disease, accounts for 25% (95% CI, 23%-28%), but is less frequent in some South American and Asian countries. Serotypes VI-IX are more common in Asia. GBS colonizes pregnant women worldwide, but prevalence and serotype distribution vary, even after adjusting for laboratory methods. Lower GBS maternal colonization prevalence, with less serotype III, may help to explain lower GBS disease incidence in regions such as Asia. High prevalence worldwide, and more serotype data, are relevant to prevention efforts. © The Author 2017. Published by

PERFORATION OF THE COLON AS A RESULT OF BLUNT ABDOMINAL TRAUMA: A CASE REPORTS

Directory of Open Access Journals (Sweden)

Arpad Ivanecz

2002-06-01

Full Text Available Background. Blunt trauma to the abdomen is more likely to damage solid organs. Blunt injuries to the colon are uncommon and usually they follows a direct blow to the abdomen. Physical findings suggesting peritoneal iritation can be present early in the postinjury period but there is usually a delay in the manifestation of colonic injury. If the colonic perforation is present as a solitary injury, signs of peritoneal iritation are easier to recognize and they lead to further evaluation and operation. Because of the force required to injure the colon, associated injuries often coexist, consequently physical findings may be masked, diagnosis delayed, and outcome compromised.Conclusions. Additionaly, the recent trend for conservative management of blunt abdominal trauma may lead to delay in diagnosis. Perioperative antibiotics and early laparotomy with complete intra-abdominal exploration and primary repair of the colon injury usually provide excellent results.

Despite major advances in the operative management of penetrating colon wounds, there remains discussion regarding the appropriate treatment of destructive colon injuries, with a significant amount of scientific evidence supporting segmental resection with primary anastomosis in most patients without comorbidities or large transfusion requirement. Although literature is sparse concerning the management of blunt colon injuries, some studies have shown operative decision based on an algorithm originally defined for penetrating wounds should be considered in blunt colon injuries. The optimal management of colonic injuries in patients requiring damage control surgery (DCS) also remains controversial. Studies have recently reported that there is no increased risk compared with patients treated without DCS if fascial closure is completed on the first reoperation, or that a management algorithm for penetrating colon wounds is probably efficacious for colon injuries in the setting of DCS as well.

Colonic Diverticulitis in the Elderly

Full Text Available Diverticular disease of the colon is a disease that mainly affects the elderly and presents in 50–70% of those aged 80 years or older. The most common complication is colonic diverticulitis. Eighty percent of patients who present with colonic diverticulitis are aged 50 years and older. Diagnosis and treatment of colonic diverticulitis in the elderly is more difficult and complicated owing to more comorbid conditions. Computed tomography is recommended for diagnosis when colonic diverticulitis is suspected. Most patients admitted with acute colonic diverticulitis respond to conservative treatment, but 15–30% of patients require surgery. Because surgery for acute colonic diverticulitis carries significant rates of morbidity and mortality, conservative treatment is recommended in the elderly. Conservative treatment of colonic diverticulitis with antibiotics, bowel rest, possibly including parenteral alimentation, is usually applied for 1–2 weeks. In the absence of a response to conservative treatment, frequent recurrence or complications (abscesses, fistulas, bowel obstructions, and free perforations, surgery is indicated.

Birth weight has inconsistent associations with colorectal cancer, possibly due to different anatomic features of the colon versus the rectum. The aim of this study was to investigate the association between birth weight and colon and rectal cancers separately. 193,306 children, born from 1936 to 1972, from the Copenhagen School Health Record Register were followed prospectively in Danish health registers. Colon and rectal cancer cases were defined using the International Classification of Disease version 10 (colon: C18.0-18.9, rectal: 19.9 and 20.9). Only cancers classified as adenocarcinomas were included in the analyses. Cox regressions were used to estimate hazard ratios (HR) and 95% confidence intervals (CI). Analyses were stratified by birth cohort and sex. During 3.8 million person-years of follow-up, 1465 colon and 961 rectal adenocarcinomas were identified. No significant sex differences were observed; therefore combined results are presented. Birth weight was positively associated with colon cancers with a HR of 1.14 (95% CI, 1.04-1.26) per kilogram of birth weight. For rectal cancer a significant association was not observed for birth weights below 3.5kg. Above 3.5kg an inverse association was observed (at 4.5kg, HR=0.77 [95% CI, 0.61-0.96]). Further, the associations between birth weight and colon and rectal cancer differed significantly from each other (p=0.006). Birth weight is positively associated with the risk of adult colon cancer, whereas the results for rectal cancer were inverse only above values of 3.5kg. The results underline the importance of investigating colon and rectal cancer as two different entities. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Bacteria causing infections in hospitalized patients are increasingly antibiotic resistant. Classical infection control practices are only partially effective at preventing spread of antibiotic-resistant bacteria within hospitals. Because the density of intestinal colonization by the highly antibiotic-resistant bacterium vancomycin-resistant Enterococcus (VRE) can exceed 109 organisms per gram of feces, even optimally implemented hygiene protocols often fail. Decreasing the density of intestinal colonization, therefore, represents an important approach to limit VRE transmission. We demonstrate that reintroduction of a diverse intestinal microbiota to densely VRE-colonized mice eliminates VRE from the intestinal tract. While oxygen-tolerant members of the microbiota are ineffective at eliminating VRE, administration of obligate anaerobic commensal bacteria to mice results in a billionfold reduction in the density of intestinal VRE colonization. 16S rRNA gene sequence analysis of intestinal bacterial populations isolated from mice that cleared VRE following microbiota reconstitution revealed that recolonization with a microbiota that contains Barnesiella correlates with VRE elimination. Characterization of the fecal microbiota of patients undergoing allogeneic hematopoietic stem cell transplantation demonstrated that intestinal colonization with Barnesiella confers resistance to intestinal domination and bloodstream infection with VRE. Our studies indicate that obligate anaerobic bacteria belonging to the Barnesiella genus enable clearance of intestinal VRE colonization and may provide novel approaches to prevent the spread of highly antibiotic-resistant bacteria.

The AIM of this retrospective study was to evaluate the emergency surgical treatment of life-threatening complications of colonic diverticula. In the last 11 years, 22 of 101 patients with colonic diverticula (22.1%) underwent urgent surgery for acute complications: perforated gangrenous diverticulitis with generalized peritonitis (n=8) or pericolic abscess (n=8), acute bowel obstruction (n=4) and severe diverticular bleeding (n=2). In all patients with diffuse peritonitis or acute obstruction the indication for surgery was decided on clinical basis and the complicated diverticula were recognized only intra-operatively. Emergency surgical strategy differed according to the type of complication and the biologic condition of the patient: segmental colectomy and primary anastomosis for diverticular perforation (n=4), colonic stenosis (n=3) or diverticular bleeding (n=2); Hartmann resection with late reconnecting anastomosis in patients with diverticular perforation (n=5) or colonic obstruction (n=1); diverticulectomy with peritoneal drainage (n=2) and colostomy and drainage followed by secondary colectomy (n=5) for diverticular perforations in patients with poor general condition. Only one patient (4.5%) died post-operatively of multiple organ failure from generalized peritonitis. There was no anastomotic leakage in patients with primary anastomosis. Six patients (27.2%) developed wound infection. Hospital stay ranged between 11 and 60 days, significantly longer in cases with two-stage operations. Primary colectomy with immediate or delayed anastomosis is the best surgical procedure for acute divericular complications in patients with good biologic status. Two-stage operations such as colostomy and drainage coupled with late colectomy remain the viable alternative in patients with advanced disease and critical biologic condition.

Current management of liver metastases of colon cancer

International Nuclear Information System (INIS)

Mainieri Breedy, Giovanna

2010-01-01

Colon cancer has been one of the major tumors in the world, both men and women; and it is constituted the third most commonly diagnosed tumor, with approximately 1.2 million of new cases per year. This cancer type is considered of great importance in Costa Rica and has occupied the fifth place. Age is the main risk factor, followed by environmental, diabetic and genetic factors. An IV colon cancer has been manifested with any T, with any N and metastases. Metastases from colon cancer to liver can be classified according to whether have been synchronous (20 to 25%) or metachronous (15 to 29%). In turn, they can be synchronous, resectable or unresectable or mechanical resectable or unresectable. The liver has been the most common site of metastases, and the status of this organ has been an important determinant of overall survival in patients with advanced disease. Half of the patients developed metastases during the course of the disease. Metastases has represented the leading cause of death from this tumor. With the advent of new surgical techniques, new anesthetic care, new chemotherapeutic and molecular agents, together with new radiofrequency modalities and ablative treatment, the approach of metastases from colon cancer to the liver has been shown to be decisive in the prolongation of survival of the patient, who in the past was considered a terminal patient [es

Current mouse models for colorectal cancer often differ significantly from human colon cancer, being largely restricted to the small intestine. Here, we aim to develop a colon-specific inducible mouse model that can faithfully recapitulate human colon cancer initiation and progression. Carbonic anhydrase I (Car1) is a gene expressed uniquely in colonic epithelial cells. We generated a colon-specific inducible Car1 CreER knock-in (KI) mouse with broad Cre activity in epithelial cells of the proximal colon and cecum. Deletion of the tumor suppressor gene Apc using the Car1 CreER KI caused tumor formation in the cecum but did not yield adenomas in the proximal colon. Mutation of both Apc and Kras yielded microadenomas in both the cecum and the proximal colon, which progressed to macroadenomas with significant morbidity. Aggressive carcinomas with some invasion into lymph nodes developed upon combined induction of oncogenic mutations of Apc, Kras, p53, and Smad4 Importantly, no adenomas were observed in the small intestine. Additionally, we observed tumors from differentiated Car1-expressing cells with Apc/Kras mutations, suggesting that a top-down model of intestinal tumorigenesis can occur with multiple mutations. Our results establish the Car1 CreER KI as a valuable mouse model to study colon-specific tumorigenesis and metastasis as well as cancer-cell-of-origin questions.

Seedlings of parasitic Cuscuta species are autotrophic but can survive only a short period of time, during which they must locate and attach to a suitable host. They have an ephemeral root-like organ considered not a "true" root by most studies. In the present study, two species with contrasting ecology were examined: Cuscuta gronovii, a North American riparian species, and Cuscuta campestris, an invasive dodder that thrives in disturbed habitats. The morphology, structure, and absorptive capability of their root-like organ were compared, their potential for colonization by two species of arbuscular mycorrhizal fungi (AMF) was assessed, and the effect of the AMF on seedling growth and survival was determined. The root of both species absorbed water and interacted with AMF, but the two species exhibited dissimilar growth and survival patterns depending on the colonization level of their seedlings. The extensively colonized seedlings of C. gronovii grew more and survived longer than non-colonized seedlings. In contrast, the scarce colonization of C. campestris seedlings did not increase their growth or longevity. The differential growth responses of the AMF-colonized and non-colonized Cuscuta species suggest a mycorrhizal relationship and reflect their ecology. While C. gronovii roots have retained a higher ability to interact with AMF and are likely to take advantage of fungal communities in riparian habitats, the invasive C. campestris has largely lost this ability possibly as an adaptation to disturbed ecosystems. These results indicate that dodders have a true root, even if much reduced and ephemeral, that can interact with AMF.

The motility of the defunctionalized colon, distal to transverse loop colostomy, has never been studied "in vivo." The aim of our study was to evaluate the influence of transverse loop colostomy on colonic motility. Thirteen patients were examined before stoma closure by means of clinical evaluation and colonic manometry; we studied both the right and distal colon in both fasting and fed patients in order to detect motor activity. Quantitative and qualitative manometric analyses showed that the diverted colon had motor activity even if no regular colonic motor pattern was observed. The spreading of aboral propagated contractions (PCs) was sometimes recorded from the right colon to the distal colon. The response of the proximal and distal colon to a standard meal, when compared to fasting values, increased more than 40 and 35 %, respectively. Stool and gas ejections from the colostomy were never related to a particular type of colonic motility: Motor quiescence such as PCs was chaotically related to stool escape. In conclusion, motility of the defunctionalized colon is preserved in patients with transverse loop colostomy.

Organizations offering accreditation services nationally or internationally to health-care provider institutions or networks at primary, secondary or tertiary level in 2010. s) External relationships, scope and activity public information. Forty-four AOs submitted data, compared with 33 in a survey 10 years earlier. Of the 30 AOs that reported survey activity in 2000 and 2010, 16 are still active and stable or growing. New and old programmes are increasingly linked to public funding and regulation. While the number of health-care AOs continues to grow, many fail to thrive. Successful organizations tend to complement mechanisms of regulation, health-care funding or governmental commitment to quality and health-care improvement that offer a supportive environment. Principal challenges include unstable business (e.g. limited market, low uptake) and unstable politics. Many organizations make only limited information available to patients and the public about standards, procedures or results.

Recurrent diverticulitis has been reported in up to 30% to 40% of patients who recover from an episode of colonic diverticular abscess, so elective interval resection is traditionally recommended. The aim of this study was to review the outcomes of patients who underwent percutaneous drainage of colonic diverticular abscess without subsequent operative intervention. This was an observational study. This investigation was conducted at a tertiary care academic medical center and a single-hospital health system. Patients treated for symptomatic colonic diverticular abscess from 2002 through 2007 were included. The primary outcomes measured were complications, recurrence, and colectomy-free survival. Two hundred eighteen patients underwent percutaneous drainage of colonic diverticular abscesses. Thirty-two patients (15%) did not undergo subsequent colonic resection. Abscess location was pelvic (n = 9) and paracolic (n = 23), the mean abscess size was 4.2 cm, and the median duration of percutaneous drainage was 20 days. The comorbidities of this group of patients included severe cardiac disease (n = 16), immunodeficiency (n = 7), and severe pulmonary disease (n = 6). Freedom from recurrence at 7.4 years was 0.58 (95% CI 0.42-0.73). All recurrences were managed nonoperatively. Recurrence was significantly associated with an abscess size larger than 5 cm. Colectomy-free survival at 7.4 years was 0.17 (95% CI 0.13-0.21). This study was limited by its retrospective, nonexperimental design and short follow-up. In selected patients, observation after percutaneous drainage of colonic diverticular abscess appears to be a safe and low-risk management option.

Laparoscopic resection of transverse colon carcinoma is technically demanding and was excluded from most of the large trials of laparoscopic colectomy. The aim of this study was to assess the safety, feasibility, and outcome of laparoscopic resection of carcinoma of the transverse colon. A retrospective review was performed to identify patients who underwent laparoscopic resection of transverse colon carcinoma. These patients were compared to patients who had laparoscopic resection for right and sigmoid colon carcinoma. In addition, they were compared to a historical series of patients who underwent open resection for transverse colon cancer. A total of 22 patients underwent laparoscopic resection for transverse colon carcinoma. Sixty-eight patients operated for right colon cancer and 64 operated for sigmoid colon cancer served as comparison groups. Twenty-four patients were identified for the historical open group. Intraoperative complications occurred in 4.5% of patients with transverse colon cancer compared to 5.9% (P = 1.0) and 7.8% (P = 1.0) of patients with right and sigmoid colon cancer, respectively. The early postoperative complication rate was 45, 50 (P = 1.0), and 37.5% (P = 0.22) in the three groups, respectively. Conversion was required in 1 (5%) patient in the laparoscopic transverse colon group. The conversion rate and late complications were not significantly different in the three groups. There was no significant difference in the number of lymph nodes harvested in the laparoscopic and open groups. Operative time was significantly longer in the laparoscopic transverse colectomy group when compared to all other groups (P = 0.001, 0.008, and transverse colectomy, respectively). The results of laparoscopic colon resection for transverse colon carcinoma are comparable to the results of laparoscopic resection of right or sigmoid colon cancer and open resection of transverse colon carcinoma. These results suggest that laparoscopic resection of transverse

The type VI secretion system encoded in SPI-6 plays a role in gastrointestinal colonization and systemic spread of Salmonella enterica serovar Typhimurium in the chicken.

Full Text Available The role of the Salmonella Pathogenicity Islands (SPIs in pathogenesis of Salmonella enterica Typhimurium infection in the chicken is poorly studied, while many studies have been completed in murine models. The Type VI Secretion System (T6SS is a recently described protein secretion system in Gram-negative bacteria. The genus Salmonella contains five phylogenetically distinct T6SS encoded in differentially distributed genomic islands. S. Typhimurium harbors a T6SS encoded in SPI-6 (T6SSSPI-6, which contributes to the ability of Salmonella to colonize mice. On the other hand, serotype Gallinarum harbors a T6SS encoded in SPI-19 (T6SSSPI-19 that is required for colonization of chicks. In this work, we investigated the role of T6SSSPI-6 in infection of chicks by S. Typhimurium. Oral infection of White Leghorn chicks showed that a ΔT6SSSPI-6 mutant had reduced colonization of the gut and internal organs, compared with the wild-type strain. Transfer of the intact T6SSSPI-6 gene cluster into the T6SS mutant restored bacterial colonization. In addition, our results showed that transfer of T6SSSPI-19 from S. Gallinarum to the ΔT6SSSPI-6 mutant of S. Typhimurium not only complemented the colonization defect but also resulted in a transient increase in the colonization of the cecum and ileum of chicks at days 1 and 3 post-infection. Our data indicates that T6SSSPI-6 contributes to chicken colonization and suggests that both T6SSSPI-6 and T6SSSPI-19 perform similar functions in vivo despite belonging to different phylogenetic families.

Caesium inhibits the colonization of Medicago truncatula by arbuscular mycorrhizal fungi

International Nuclear Information System (INIS)

Wiesel, Lea; Dubchak, Sergiy; Turnau, Katarzyna; Broadley, Martin R.; White, Philip J.

2015-01-01

Contamination of soils with radioisotopes of caesium (Cs) is of concern because of their emissions of harmful β and γ radiation. Radiocaesium enters the food chain through vegetation and the intake of Cs can affect the health of organisms. Arbuscular mycorrhizal (AM) fungi form mutualistic symbioses with plants through colonization of the roots and previous studies on the influence of AM on Cs concentrations in plants have given inconsistent results. These studies did not investigate the influence of Cs on AM fungi and it is therefore not known if Cs has a direct effect on AM colonization. Here, we investigated whether Cs influences AM colonization and if this effect impacts on the influence of Rhizophagus intraradices on Cs accumulation by Medicago truncatula. M. truncatula was grown with or without R. intraradices in pots containing different concentrations of Cs. Here, we present the first evidence that colonization of plants by AM fungi can be negatively affected by increasing Cs concentrations in the soil. Mycorrhizal colonization had little effect on root or shoot Cs concentrations. In conclusion, the colonization by AM fungi is impaired by high Cs concentrations and this direct effect of soil Cs on AM colonization might explain the inconsistent results reported in literature that have shown increased, decreased or unaffected Cs concentrations in AM plants. - Highlights: • Colonization of plants by arbuscular mycorrhizal fungi is negatively affected by increasing soil caesium concentrations. • Shoot caesium concentrations are not influenced by AM fungi at soil caesium concentrations above about 3 μg Cs kg −1 . • The direct effect of caesium on AM fungi might impact on the influence of AM fungi on Cs accumulation in plants. • This might explain the inconsistent results reported in literature on Cs accumulation in AM plants

Full Text Available Cognitive robotics research draws inspiration from theories and models on cognition, as conceived by neuroscience or cognitive psychology, to investigate biologically plausible computational models in artificial agents. In this field, the theoretical framework of Grounded Cognition provides epistemological and methodological grounds for the computational modeling of cognition. It has been stressed in the literature that textit{simulation}, textit{prediction}, and textit{multi-modal integration} are key aspects of cognition and that computational architectures capable of putting them into play in a biologically plausible way are a necessity.Research in this direction has brought extensive empirical evidencesuggesting that textit{Internal Models} are suitable mechanisms forsensory-motor integration. However, current Internal Models architectures show several drawbacks, mainly due to the lack of a unified substrate allowing for a true sensory-motor integration space, enabling flexible and scalable ways to model cognition under the embodiment hypothesis constraints.We propose the Self-Organized Internal ModelsArchitecture (SOIMA, a computational cognitive architecture coded by means of a network of self-organized maps, implementing coupled internal models that allow modeling multi-modal sensory-motor schemes. Our approach addresses integrally the issues of current implementations of Internal Models.We discuss the design and features of the architecture, and provide empirical results on a humanoid robot that demonstrate the benefits and potentialities of the SOIMA concept for studying cognition in artificial agents.

To observe the effect of manual acupuncture stimulation of different layers (skin, muscle, peritoneum, sub-peritoneum) of "Tianshu" (ST 25) region on proximal colonic pressure in normal rats. Forty-eight male SD rats were divided into 6 groups: all layer-needling, brushing, cutaneous needling, muscular needling, peritoneum-needling and sub-peritoneum-needling groups ( n ＝8 in each group). Manual needling or brushing was applied to "Tianshu" (ST 25) region. The colonic internal pressure was measured by using an amplifier and a pressure transducer-connected balloon which was implanted into the colonic cavity about 6 cm from the ileocecal valve. For rats of the all-layer needling group, an acupuncture needle was inserted into ST 25 about 1 cm deep and rotated for a while, for rats of the brushing group, a Chinese calligraphy brush pen was used to brush the skin hair for 1 min. For rats of the rest 4 groups, an acupuncture needle was inserted into the skin, muscle layer after cutting open the skin (about 0.1 cm), the peritoneum layer after cutting open the skin and muscle layers, and the sub-peritoneum layer after cutting open the skin, muscle and peritoneum layers, respectively, and rotated using the uniform reinforcing-reducing technique for about 1 min at a frequency of 120 twirlings per minute every time. During manual needling stimulation of the full layers, cutaneous layer, muscle layer, peritoneum layer and the sub-peritoneum layer of bilateral "Tianshu" (ST 25), the internal pressure of proximal colon was significantly decreased relevant to pre-stimulation in each group ( P 0.05). During hair brushing of ST 25 region, the colonic pressure was observably increased relevant to pre-needling stimulation ( P ST 25 on both sides may lower internal pressure of proximal colon in normal rats, suggesting their involvement of acupuncture effect in relaxing proximal colonic contraction.

The role of primary repair (PR) of modern day war-related colon injuries remains controversial. Retrospective review of medical records of combat-wounded soldiers with colon injuries sustained during March 2003 to August 2006 was conducted. Injuries were analyzed according to location: right (n = 30), transverse (n = 13), and left (n = 24) sided colon injuries. Two-tailed Fisher's Exact or chi tests were used for statistical analysis. Seventy-seven soldiers returned to Walter Reed Army Medical Center with colon injuries suffered during Operations Enduring Freedom and Iraqi Freedom. Twelve patients with minor colon injuries were excluded. The remaining 65 patients (mean age, 28 +/- 7 years) sustained 67 colon injuries from secondary blast (n = 38); gunshot (n = 27); motor vehicle crash (n = 1) and crush injury (n = 1). Patients arrived at Walter Reed Army Medical Center 5 days (range, 2-16 days) after injury and damage control operations (n = 27, 42%), and were hospitalized for a median of 22 days (range, 1-306 days). Follow-up averaged 311 days (median, 198 days). PR was attempted in right (n = 18, 60%), transverse (n = 11, 85%), and left (n = 9, 38%) sided colon injuries. Delayed definitive treatment of colon injuries occurred in 42% of patients. Failure of repair occurred in 16% of patients and was more likely with concomitant pancreatic, stomach, splenic, diaphragm, and renal injuries. Overall morbidity for ostomy closure after primary ostomy formation was 30%, but increased to 75% for ostomy closure after primary anastomotic or repair failure. PR of war-related colon injuries can be performed safely in selected circumstances in the absence of concomitant organ injury. Delayed anastomosis can often be performed after damage control operations once the patient stabilizes. Ostomy closure complications are more likely after anastomotic failure.

The maintenance and resilience of host-associated microbiota during development is a fundamental process influencing the fitness of many organisms. Several host properties were identified as influencing factors on bacterial colonization, including the innate immune system, mucus composition, and diet. In contrast, the importance of bacteria–bacteria interactions on host colonization is less understood. Here, we use bacterial abundance data of the marine model organism Nematostella vectensis to reconstruct potential bacteria–bacteria interactions through co-occurrence networks. The analysis indicates that bacteria–bacteria interactions are dynamic during host colonization and change according to the host’s developmental stage. To assess the predictive power of inferred interactions, we tested bacterial isolates with predicted cooperative or competitive behavior for their ability to influence bacterial recolonization dynamics. Within 3 days of recolonization, all tested bacterial isolates affected bacterial community structure, while only competitive bacteria increased bacterial diversity. Only 1 week after recolonization, almost no differences in bacterial community structure could be observed between control and treatments. These results show that predicted competitive bacteria can influence community structure for a short period of time, verifying the in silico predictions. However, within 1 week, the effects of the bacterial isolates are neutralized, indicating a high degree of resilience of the bacterial community. PMID:29740401

In locally advanced primary transverse colon cancer, a tumor may cause perforation or invade adjacent organs. Extensive resection is the best choice of treatment, but such procedures must be weighed against the potential survival benefits. This study was performed to identify the clinicopathological features and treatment outcomes of such tumors. We retrospectively reviewed the database of the Colorectal Cancer Registry of Chang Gung Memorial Hospital between February 1995 and December 2005. Patients with colon cancer sited between the hepatic and splenic flexure that involved an adjacent organ without distant metastasis were defined as having locally advanced transverse colon cancer. A total of 827 patients who underwent surgery for transverse primary colon cancer were enrolled in the study. Stage II and stage III colon cancer were diagnosed in 548 patients. Thirty-two (5.8%) patients were diagnosed with locally advanced tumors. Multivariate analysis revealed that stage III, preoperative carcinoembryonic antigen ≥5 ng/mL, a tumor with perforation or obstruction, and the presence of a locally advanced tumor were significant prognostic factors for both overall and cancer-specific survival. Postoperative morbidity rates differed significantly between the locally advanced and non-locally advanced tumor groups (22.7% vs. 12.3%, P transverse colon tumors (P = 0.21). Surgical resection of locally advanced transverse colon tumors resulted in a higher morbidity and mortality than that of non-locally advanced tumors, but the benefit of extensive surgery in the case of locally advanced tumors cannot be underestimated. Furthermore, this benefit is more pronounced in the case of stage II tumors.

We evaluated the protective effects of fermented dairy products (FDPs) in an infection model, using the mouse pathogen Citrobacter rodentium (CR). Treatment of mice with FDP formulas A, B, and C or a control product did not affect CR colonization, organ specificity, or attaching and effacing lesion formation. Fermented dairy product A (FDP-A), but neither the supernatant from FDP-A nor β-irradiated (IR) FDP-A, caused a significant reduction in colonic crypt hyperplasia and CR-associated pathology. Profiling the gut microbiota revealed that IR-FDP-A promoted higher levels of phylotypes belonging to Alcaligenaceae and a decrease in Lachnospiraceae (Ruminococcus) during CR infection. Conversely, FDP-A prevented a decrease in Ruminococcus and increased Turicibacteraceae (Turicibacter). Importantly, loss of Ruminococcus and Turicibacter has been associated with susceptibility to dextran sodium sulfate-induced colitis. Our results demonstrate that viable bacteria in FDP-A reduced CR-induced colonic crypt hyperplasia and prevented the loss of key bacterial genera that may contribute to disease pathology. © The Author 2014.

Full Text Available Abstract Choriocarcinoma usually arises in the uterus and gonads. Primary choriocarcinoma (PCC in an extragenital organ is rare. When it occurs in the gastrointestinal tract, the stomach is the most common site. Only 12 cases of PCC of the colon have been reported in the world literature. Most cases were associated with adenocarcinoma. We report the case of a 36-year-old man with PCC of the colon and review the clinical characteristics of previously documented cases.

Carotenoids have numerous biological properties that may underpin a role for them as chemopreventive agents. However, except for beta-carotene, little is known about how dietary carotenoids are associated with common cancers, including colon cancer. The objective of this study was to evaluate associations between dietary alpha-carotene, beta-carotene, lycopene, lutein, zeaxanthin, and beta-cryptoxanthin and the risk of colon cancer. Data were collected from 1993 case subjects with first primary incident adenocarcinoma of the colon and from 2410 population-based control subjects. Dietary data were collected from a detailed diet-history questionnaire and nutrient values for dietary carotenoids were obtained from the US Department of Agriculture-Nutrition Coordinating Center carotenoid database (1998 updated version). Lutein was inversely associated with colon cancer in both men and women [odds ratio (OR) for upper quintile of intake relative to lowest quintile of intake: 0.83; 95% CI: 0.66, 1.04; P = 0.04 for linear trend]. The greatest inverse association was observed among subjects in whom colon cancer was diagnosed when they were young (OR: 0.66; 95% CI: 0.48, 0.92; P = 0.02 for linear trend) and among those with tumors located in the proximal segment of the colon (OR: 0.65; 95% CI: 0.51, 0.91; P lettuce, tomatoes, oranges and orange juice, carrots, celery, and greens. These data suggest that incorporating these foods into the diet may help reduce the risk of developing colon cancer.

This retrospective study was conducted to identify potential risk factors for Acinetobacter baumannii (A. baumannii) ventilator-associated pneumonia (VAP) and evaluate the association between Candida spp. airway colonization and A. baumannii VAP. Intensive care unit (ICU) patients who were on mechanical ventilation (MV) for ≥48 hours were divided into the following groups: patients with and without Candida spp. airway colonization; colonized patients receiving antifungal treatment or not; patients with A. baumannii VAP and those without VAP. Logistic regression analysis and propensity score matching were used to identify factors independently associated with A. baumannii VAP. Among 618 eligible patients, 264 (43%) had Candida spp. airway colonization and 114 (18%) developed A. baumannii VAP. Along with MV for ≥7 days (adjusted odds ratio [aOR] 8.9, 95% confidence intervals [95% CI] 4.9-15.8) and presence of a central venous catheter (aOR 3.2, 95% CI 1.1-9), Candida spp. airway colonization (aOR 2.6, 95% CI 1.6-4.3) was identified as an independent risk factor for A. baumannii VAP. Patients with Candida spp. airway colonization were more likely to develop A. baumannii VAP than non-colonized patients (23% vs 15%, P=.01 and 34% vs. 15%, PCandida spp. airway colonization (43%) and A. baumannii VAP (18%) were common in ICU patients who were on mechanical ventilation for at least 48 hours. Candida spp. airway colonization was an independent risk factor for subsequent A. baumannii VAP. © The Author 2016.

Full Text Available Being one of the largest movements of displaced people through European borders since World War Two, the Syrian refugee crisis of 2015 and 2016, tested the coordination of the states and international organizations, and as well as the strategies for response of the latter to such enormous fluxes of displaced people along the Balkan corridor. The quick on-time reaction of the specialized humanitarian international organizations made significant achievements by the international organizations in terms of humanitarian assistance for the refugees and support for the governments of the region. Their approach mainly sought to create a partnership with the governments of the Balkan route in handling the serious humanitarian challenges (with a different strategy compared to other experiences, mainly this time through providing assistance and protection to the refugees throughout the corridor of the refugee crisis, it showed how important is such coordination at the end, with an aim to avoid further human catastrophes along refugee routes, and to avoid major security repercussions for the countries of the region.

Most colon trauma data arise from institutional series that provide descriptive analysis. We investigated the outcome of these patients by analyzing a nationwide database. We queried the U.S. National Trauma Data Bank (2007-2009) using primary International Classification of Diseases, 9th edition, Clinical Modification codes to identify colon injuries. Outcomes were stratified by injury mechanism (blunt versus penetrating), segment of colon injured, and management strategy (diversion versus in continuity). There were 6,817 patients who suffered primary colon injuries; 82% were male and 48% experienced blunt injuries. Blunt colon trauma patients were older, had lengthier intensive care stays, and greater rates of morbidity and mortality than those with penetrating injuries (all P colon injuries (24%). The overall fecal diversion rate was 9%, with the highest rates seen in patients with sigmoid colon injuries (15%). Diverted patients were older, had higher injury severity scores, and increased mortality (22% vs 12%; P colon injuries seem to be managed with fecal diversion more often than other segmental injuries. Neither blunt mechanism nor fecal diversion were independently associated with adverse outcomes in colon trauma. Copyright © 2013 Mosby, Inc. All rights reserved.

The objective of this study is comparing colon diversion versus primary repair in penetrating colon gunshot injuries. A retrospective study of 63 cases of gunshot abdomen with penetrating colon injury were admitted to Al-jalla Hospital in 2011 in Benghazi, Libya. After surgical intervention, these patients were observed for any postoperative complications. During the study period, 63 eligible patients included, 62 (98.4%) were males and 1 (1.6%) was female. And the mean age was 29.24 years. Eighteen patients had an injury on the right side of the colon, while 16, 6, 11, 6, 2, 3, and 1 patients had an injury on the transverse, left, sigmoid, rectum, right transverse, left transverse, and total colonic injury, respectively. In the first group, 23 patients (36.5%) was treated with colon diversion, (2 with Hartmann's operation, 21 with loop colostomy). In the second group, 40 patients (63.4 %) was treated with primary repair. Eighteen (28.5%) with right hemicolectomy, 5 (7.9%) with transverse colon resection and anastomosis, and 17 (26.9%) with simple repair. We evaluate the rate of postoperative complication and compare the postoperative morbidity between both groups. In our study, there was no significant statistical difference between types of operations and rate of complications (P = 0.18). We could not see any advantage of the diversion over the primary repair. To reduce risk of the psychological trauma, complications of colostomy, unnecessary repeated hospitalization, decrease of economic cost, and complications of stoma revision operation, we should consider that the primary repair of penetrating colon injuries is an acceptable alternative method of treatment over the colostomy.

Elevators are ubiquitous and active inside hospitals, potentially facilitating bacterial transmission. The objective of this study was to estimate the prevalence of bacterial colonization on elevator buttons in large urban teaching hospitals. A total of 120 elevator buttons and 96 toilet surfaces were swabbed over separate intervals at 3 tertiary care hospitals on weekdays and weekends in Toronto, Ontario. For the elevators, swabs were taken from 2 interior buttons (buttons for the ground floor and one randomly selected upper-level floor) and 2 exterior buttons (the "up" button from the ground floor and the "down" button from the upper-level floor). For the toilet surfaces, swabs were taken from the exterior and interior handles of the entry door, the privacy latch, and the toilet flusher. Samples were obtained using standard bacterial collection techniques, followed by plating, culture, and species identification by a technician blind to sample source. The prevalence of colonization of elevator buttons was 61% (95% confidence interval 52%-70%). No significant differences in colonization prevalence were apparent in relation to location of the buttons, day of the week, or panel position within the elevator. Coagulase-negative staphylococci were the most common organisms cultured, whereas Enterococcus and Pseudomonas species were infrequent. Elevator buttons had a higher prevalence of colonization than toilet surfaces (61% v. 43%, p = 0.008). Hospital elevator buttons were commonly colonized by bacteria, although most pathogens were not clinically relevant. The risk of pathogen transmission might be reduced by simple countermeasures.

Microbial Surface Colonization and Biofilm Development in Marine Environments

Science.gov (United States)

2015-01-01

SUMMARY Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms. Surface colonization and subsequent biofilm formation and development provide numerous advantages to these organisms and support critical ecological and biogeochemical functions in the changing marine environment. Microbial surface association also contributes to deleterious effects such as biofouling, biocorrosion, and the persistence and transmission of harmful or pathogenic microorganisms and their genetic determinants. The processes and mechanisms of colonization as well as key players among the surface-associated microbiota have been studied for several decades. Accumulating evidence indicates that specific cell-surface, cell-cell, and interpopulation interactions shape the composition, structure, spatiotemporal dynamics, and functions of surface-associated microbial communities. Several key microbial processes and mechanisms, including (i) surface, population, and community sensing and signaling, (ii) intraspecies and interspecies communication and interaction, and (iii) the regulatory balance between cooperation and competition, have been identified as critical for the microbial surface association lifestyle. In this review, recent progress in the study of marine microbial surface colonization and biofilm development is synthesized and discussed. Major gaps in our knowledge remain. We pose questions for targeted investigation of surface-specific community-level microbial features, answers to which would advance our understanding of surface-associated microbial community ecology and the biogeochemical functions of these communities at levels from molecular mechanistic details through systems biological integration.

Background and purpose: in radiotherapy for prostate cancer, the rectum is considered the dose-limiting organ. The incidence of overlap between the sigmoid colon and/or small bowel and the planning target volume (PTV) as well as the dose to sigmoid colon and small bowel were investigated. Patients and methods: the CT data of 75 prostate cancer patients were analyzed. The clinical target volume (CTV) consisted of prostate and seminal vesicles. The PTV was defined as a three-dimensional expansion of the CTV with a 10-mm margin in craniocaudal and a 7-mm margin in the other directions. All patients were planned to a mean CTV dose of at least 76 Gy. Minimum CTV dose was set at 70 Gy. Dose inhomogeneity within the CTV was kept between 12% and 17%. Sigmoid colon was defined upward from the level where the rectum turned in a transverse plane. Contrast-filled small bowel was contoured on all slices where it was visible. The presence of sigmoid colon and/or small bowel in close vicinity to or overlapping with the PTV was recorded. For each case, the dose to the sigmoid colon and small bowel was calculated. Results: the PTV was found to overlap with the sigmoid colon in 60% and with the small bowel in 19% of the cases. In these patients, mean maximum dose to the sigmoid colon was 76.2 Gy (5th-95th percentile: 70.0-80.7 Gy). Mean maximum dose to the small bowel was 74.9 Gy (5th-95th percentile: 68.0-80.0 Gy). Conclusion: when systematically investigating the anatomic position of sigmoid colon and small bowel in patients accepted for prostate irradiation, parts of both organs were often observed in close vicinity to the PTV. Apart from the rectum, these organs may be dose-limiting in prostate radiotherapy. (orig.)

In these patients, mean maximum dose to the sigmoid colon was 76.2 Gy (5th-95th percentile: 70.0-80.7 Gy). Mean maximum dose to the small bowel was 74.9 Gy (5th-95th percentile: 68.0-80.0 Gy). Conclusion: when systematically investigating the anatomic position of sigmoid colon and small bowel in patients accepted for prostate irradiation, parts of both organs were often observed in close vicinity to the PTV. Apart from the rectum, these organs may be dose-limiting in prostate radiotherapy. (orig.)

2013-01-01

Why do states choose to join and form international governmental organizations (IGOs) that regulate energy policy? In this article we make three specific contributions to the literature on international cooperation and diffusion. First, we show that countries form and join energy IGOs in response to memberships previously gained by direct competitors among oil and gas producers and consumers. Moreover, we demonstrate that energy IGOs diffuse among countries that share oil and gas pipelines. F...

Manuel Montobbio

2006-01-01

Full Text Available What does the presence of Spaniards in international organisations signify and entail? Why, for what, and how should this be promoted? In order to answer such questions, the author analyses the meaning and implications of this presence in a globalised world in which a commitment to effective multilateralism entails a commitment to the international organisms as forums for and actors in global governance, and their presence in our societies and lives. This means both the promoting of Spanish presence in the administrations inwhich the proposals are formed which embody the general interest of the international organisations, like the multilateralisation of Spanish society. For this reason, in the framework of its multilateral policy, Spain is currently developing a policy of promoting the presence of Spaniards in international organisations in the areas of information, training, promotion and incentives, the outlines and results of which are described in this article.

Full Text Available Knowledge-based organizations are constructed on intangible assets, such as the expertise and the values of the employees. As a consequence, motivation and professional excellence of employees are the main objectives of management teams. For this type of organizations, considered as true “knowledge systems”, the employees represent the most valuable resource that is not motivated only through financial means, but also through internal communication, autonomy or social rewards. The research of Eurofound shows that knowledge-based organizations have a low number of trade unions, while professional associations are more relevant for them. There is no tradition to defend through negotiation the working conditions of employees, thus it is important for managers to use the best practices, in order to increase the employees’ loyalty. We conducted a qualitative research concerning the quality of professional life of employees in five sectors of knowledge-based services: advertising-marketing, IT, banking and finance, research and development, and higher education; 15-20 employees from each sector were interviewed. Some of the questions referred directly to trade unions and affiliation, and also to internal communication. Although the results showed a different situation in each of the five sectors, there are few common characteristics: descendant communication is more frequent than ascendant communication, trade unions were reported as missing, unrepresentative or not very active, and the greatest part of employees in this sector are not affiliated, facts that limits the possibility of maintaining employees’ motivation on long term.

In recent years, the fabrication of patient organ replicas using 3D printers has been attracting a great deal of attention in medical fields. However, the cost of these organ replicas is very high as it is necessary to employ very expensive 3D printers and printing materials. Here we present a new gel organ replica, of human kidney, fabricated with a conventional molding technique, using a particle-double network hydrogel (P-DN gel). The replica is transparent and has the feel of a real kidney. It is expected that gel organ replicas produced this way will be a useful tool for the education of trainee surgeons and clinical ultrasonography technologists. In addition to developing a gel organ replica, the internal structure of the P-DN gel used is also discussed. Because the P-DN gel has a complex structure comprised of two different types of network, it has not been possible to investigate them internally in detail. Gels have an inhomogeneous network structure. If it is able to get a more uniform structure, it is considered that this would lead to higher strength in the gel. In the present study we investigate the structure of P-DN gel, using the gel organ replica. We investigated the internal structure of P-DN gel using Scanning Microscopic Light Scattering (SMILS), a non-contacting and non-destructive.

Candidatus Renichlamydia lutjani, a Gram-negative bacterium in internal organs of blue striped snapper Lutjanus kasmira from Hawaii

2012-01-01

The blue-striped snapper Lutjanus kasmira (Perciformes, Lutjanidae) are cosmopolitan in the Indo-Pacific but were introduced into Oahu, Hawaii, USA, in the 1950s and have since colonized most of the archipelago. Studies of microparasites in blue-striped snappers from Hawaii revealed chlamydia-like organisms (CLO) infecting the spleen and kidney, characterized by intracellular basophilic granular inclusions containing Gram-negative and Gimenez-positive bacteria similar in appearance to epitheliocysts when seen under light microscopy. We provide molecular evidence that CLO are a new member of Chlamydiae, i.e. Candidatus Renichlamydia lutjani, that represents the first reported case of chlamydial infection in organs other than the gill in fishes.

2015-12-01

Full Text Available We report a patient with supraclavicular lymph node metastasis from an undetectable adenocarcinoma of the transverse colon, who presented with cough and was diagnosed with typhoid fever, bronchitis as well as liver metastasis. There were an abdominal fullness, weight loss, constipation, pencil-like stool with mucous and blood, low-grade fever, bone ache, and tea-color urine. The first colonoscopy revealed lymphocytic ileitis and microscopic findings also showed lymphocytic ileitis. Abdominal USG and CT revealed liver metastasis of unknown origin. Based on the clinical sign and symptoms, we suspected that colorectal carcinoma was the primary site. Then, the second colonoscopy was performed and it revealed a small polyp, which was followed with a biopsy and the result supported a well-differentiated colon adenocarcinoma. Similar result was also revealed by the histopathological evaluation. This is an unusual case of liver and supraclavicular lymph node metastasis arising from a small polyp adenocacinoma of the transverse colon. Key words: liver metastase, colorectal carcinoma, lymph node.

Politics of Internationalism - Danish Women's Movements Participating in the Building of International Women's Organizations (1888-1919)

Fiig, Christina; Nielsen, Jytte

2016-01-01

The struggle for universal enfranchisement in Denmark went on for almost 70 years and was part of a broader struggle for democratization. Granting women the vote was controversial and affected fundamental power structures and male privileges in marriage, in the labor market and in politics (Fiig...... & Siim 2008: 61). The context for this political and ideological struggle was primarily local and national; however there are reasons to investigate the international inspiration and activism as a central part of the debate and struggle for enfranchisement. In this article, we move beyond the “national...... container” (Beck XX) of Denmark in the time period of 1888-1915 and analyze both the international inspiration in relation to the women’s organizations and the Danish women’s movements’ important role on the international scene....

Simões-Silva, Liliana; Correia, Inês; Barbosa, Joana; Santos-Araujo, Carla; Sousa, Maria João; Pestana, Manuel; Soares-Silva, Isabel; Sampaio-Maia, Benedita

Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

Usually, left colon cancer metastasis concerns liver, abdominal lymph nodes and lungs. Other localizations are quite rare occurrences. In spite of this, some uncommon metastasis sites are reported in literature, such as: peritoneum, ovaries, uterus, kidney testis, bones, thyroid, oral cavity and central nervous system. We report two cases of unusual localizations of left colon cancer metastasis localization, one into the retroperitoneal space and the other at the left axillary lynphnodes and between liver and pancreas. In the first reported case the diffusion pathway may have been the lymphatic mesocolic vessels, partially left in place from the previous surgery. In the second case the alleged metastatic lane may have been through the periumbilical lymph nodes to the parasternal lymph nodes and then to the internal mammary ones, finally reaching the axillary limph nodes.

According to the adenoma-carcinoma sequence, colon cancer results from accumulating somatic gene mutations; environmental growth factors accelerate and augment this process. For example, diets rich in meat and fat increase fecal bile acids and colon cancer risk. In rodent cancer models, increased fecal bile acids promote colon dysplasia. Conversely, in rodents and in persons with inflammatory bowel disease, low-dose ursodeoxycholic acid treatment alters fecal bile acid composition and attenuates colon neoplasia. In the course of elucidating the mechanism underlying these actions, we discovered that bile acids interact functionally with intestinal muscarinic receptors. The present communication reviews muscarinic receptor expression in normal and neoplastic colon epithelium, the role of autocrine signaling following synthesis and release of acetylcholine from colon cancer cells, post-muscarinic receptor signaling including the role of transactivation of epidermal growth factor receptors and activation of the ERK and PI3K/AKT signaling pathways, the structural biology and metabolism of bile acids and evidence for functional interaction of bile acids with muscarinic receptors on human colon cancer cells. In murine colon cancer models, deficiency of subtype 3 muscarinic receptors attenuates intestinal neoplasia; a proof-of-concept supporting muscarinic receptor signaling as a therapeutic target for colon cancer.

We report two cases of diffuse hemangioma of the colon in adolescent patients. One patient had multiple phleboliths at the lower pelvis identified with plain radiographs of the abdomen. Several aspects were seen on double-contrast enema: luminal narrowing, colonic-wall thickening and submucosal colonic masses that changed in appearance with the degree of colonic distension. Angiography was inconclusive in one case. Use of CT and MR provided relevant information regarding the true extent of the disease, but MR was superior in demonstrating unequivocally the vascular nature of the lesions. (orig.)

The marine epiphytic bacterium Pseudoalteromonas tunicata produces a range of extracellular secondary metabolites that inhibit an array of common fouling organisms, including fungi. In this study, we test the hypothesis that the ability to inhibit fungi provides P. tunicata with an advantage during colonization of a surface. Studies on a transposon-generated antifungal-deficient mutant of P. tunicata, FM3, indicated that a long-chain fatty acid-coenzyme A ligase is involved in the production of a broad-range antifungal compound by P. tunicata. Flow cell experiments demonstrated that production of an antifungal compound provided P. tunicata with a competitive advantage against a marine yeast isolate during surface colonization. This compound enabled P. tunicata to disrupt an already established fungal biofilm by decreasing the number of yeast cells attached to the surface by 66% +/- 9%. For in vivo experiments, the wild-type and FM3 strains of P. tunicata were used to inoculate the surface of the green alga Ulva australis. Double-gradient denaturing gradient gel electrophoresis analysis revealed that after 48 h, the wild-type P. tunicata had outcompeted the surface-associated fungal community, whereas the antifungal-deficient mutant had no effect on the fungal community. Our data suggest that P. tunicata is an effective competitor against fungal surface communities in the marine environment.

Streptococcus pneumoniae biofilm formation and dispersion during colonization and disease

Streptococcus pneumoniae (the pneumococcus) is a common colonizer of the human nasopharynx. Despite a low rate of invasive disease, the high prevalence of colonization results in millions of infections and over one million deaths per year, mostly in individuals under the age of 5 and the elderly. Colonizing pneumococci form well-organized biofilm communities in the nasopharyngeal environment, but the specific role of biofilms and their interaction with the host during colonization and disease is not yet clear. Pneumococci in biofilms are highly resistant to antimicrobial agents and this phenotype can be recapitulated when pneumococci are grown on respiratory epithelial cells under conditions found in the nasopharyngeal environment. Pneumococcal biofilms display lower levels of virulence in vivo and provide an optimal environment for increased genetic exchange both in vitro and in vivo, with increased natural transformation seen during co-colonization with multiple strains. Biofilms have also been detected on mucosal surfaces during pneumonia and middle ear infection, although the role of these biofilms in the disease process is debated. Recent studies have shown that changes in the nasopharyngeal environment caused by concomitant virus infection, changes in the microflora, inflammation, or other host assaults trigger active release of pneumococci from biofilms. These dispersed bacteria have distinct phenotypic properties and transcriptional profiles different from both biofilm and broth-grown, planktonic bacteria, resulting in a significantly increased virulence in vivo. In this review we discuss the properties of pneumococcal biofilms, the role of biofilm formation during pneumococcal colonization, including their propensity for increased ability to exchange genetic material, as well as mechanisms involved in transition from asymptomatic biofilm colonization to dissemination and disease of otherwise sterile sites.

2018-05-21

The diagnosis of invasive aspergillosis remains challenging in solid organ transplants in general, and in lung transplant recipients, in particular, because of colonization. Lung transplant recipients may be over treated with antifungal drugs because of the lack of appropriate diagnostic tools. A review of the new developments of diagnostic tools and whether this help distinguishing colonization from invasive disease is presented. Efforts are being made to develop new tools that will allow us to identify which patients will develop IPA, and those who will be able to control the disease.

Piriformospora indica root colonization triggers local and systemic root responses and inhibits secondary colonization of distal roots.

Science.gov (United States)

Pedrotti, Lorenzo; Mueller, Martin J; Waller, Frank

2013-01-01

Piriformosporaindica is a basidiomycete fungus colonizing roots of a wide range of higher plants, including crop plants and the model plant Arabidopsis thaliana. Previous studies have shown that P. indica improves growth, and enhances systemic pathogen resistance in leaves of host plants. To investigate systemic effects within the root system, we established a hydroponic split-root cultivation system for Arabidopsis. Using quantitative real-time PCR, we show that initial P. indica colonization triggers a local, transient response of several defense-related transcripts, of which some were also induced in shoots and in distal, non-colonized roots of the same plant. Systemic effects on distal roots included the inhibition of secondary P. indica colonization. Faster and stronger induction of defense-related transcripts during secondary inoculation revealed that a P. indica pretreatment triggers root-wide priming of defense responses, which could cause the observed reduction of secondary colonization levels. Secondary P. indica colonization also induced defense responses in distant, already colonized parts of the root. Endophytic fungi therefore trigger a spatially specific response in directly colonized and in systemic root tissues of host plants.

Colon Cancer Detection by ‘Rendezvous Colonoscopy’: Successful Removal of Stuck Colon Capsule by Conventional Colonoscopy

Directory of Open Access Journals (Sweden)

István Rácz

2010-02-01

Full Text Available Although capsule retention is a known complication of small bowel capsule endoscopy, initial studies with colon capsule endoscopy (CCE have not reported any capsule retention or sticking neither in the small bowel nor in the colon. We report a complication of CCE when the stuck colon capsule was passed through the malignant colon stricture and removed by the aid of a flexible colonoscope. During CCE in a 76-year-old iron deficiency anemia patient the real-time viewing system indicated the colon capsule to be stuck in a malignant ascending colon stricture for more than two hours. With the aim to avoid complete capsule retention, immediate colonoscopy was performed. The stuck capsule was caught by a polypectomy snare, passed through the tumor stricture and finally removed from the large bowel. The current case describes the usefulness of the real-time viewing system. Similar situations may occur during the forthcoming spread of CCE and the present case is an example of how to manage the potentially risky stuck colon capsule condition.

International ITER fusion energy organization. Paving the way to power generation from nuclear fusion

Preuschen-Liebenstein, R. von

2006-01-01

ITER (Latin: the way) is the acronym of a new international large research facility gradually taking shape after the meeting of Gorbachev and Reagan in Reykjavik in 1985. Under the auspices of the IAEA, worldwide scientific and industrial cooperation with 'home teams' of each of the ITER partners began at that time which were commissioned to accumulate the knowledge and the technology of nuclear fusion in the participating countries. At the end of the preparation and decisionmaking process, the design draft of the ITER reactor was elaborated in international cooperation as the basis of the ITER Convention. After lengthy negotiations among the international ITER partners, a European site for the ITER organization and its reactor was found at Cadarache, France. As the first ITER member, Europe now initiated worldwide cooperation in research and development, seeking to demonstrate the technical and scientific feasibility of tapping fusion power for peaceful purposes. The Council of the European Union (competitiveness), at its meeting on September 25, 2006, decided to sign the ITER Convention about the establishment of the International ITER Fusion Energy Organization ('ITER Organization') and about the mutual obligation to make the necessary contributions towards the construction of ITER.

Asbestos and Asbestos-related Diseases in Vietnam: In reference to the International Labor Organization/World Health Organization National Asbestos Profile

Directory of Open Access Journals (Sweden)

Van Hai Pham

2013-06-01

Full Text Available This paper describes progress on formulating a national asbestos profile for the country of Vietnam. The Center of Asbestos Resource, Vietnam, formulated a National Profile on Asbestos-related Occupational Health, with due reference to the International Labor Organization/World Health Organization National Asbestos Profile. The Center of Asbestos Resource was established by the Vietnamese Health Environment Management Agency and the National Institute of Labor Protection, with the support of the Australian Agency for International Development, as a coordinating point for asbestos-related issues in Vietnam. Under the National Profile on Asbestos-related Occupational Health framework, the Center of Asbestos Resource succeeded in compiling relevant information for 15 of the 18 designated items outlined in the International Labor Organization/World Health Organization National Asbestos Profile, some overlaps of the information items notwithstanding. Today, Vietnam continues to import and use an average of more than 60,000 metric tons of raw asbestos per year. Information on asbestos-related diseases is limited, but the country has begun to diagnose mesothelioma cases, with the technical cooperation of Japan. As it stands, the National Profile on Asbestos-related Occupational Health needs further work and updating. However, we envisage that the National Profile on Asbestos-related Occupational Health will ultimately facilitate the smooth transition to an asbestos-free Vietnam.

The paper presents the progress registered by the Radionuclide Metrology Laboratory (RML) from IFIN-HH, in improvement of the quality of radiopharmaceuticals activity measurement, and assurance of the whole traceability chain from international level to the national users. The progress in organization of comparisons for radiopharmaceuticals activity measurement is analyzed. A detailed description of two recent national comparisons, and an international one, regarding 131 I solutions, within the frame of the IAEA's CRP E2.10.05 'Harmonization of quality practices for nuclear medicine radioactivity measurements' is done, with the analysis of the strong and week points in measurements. The most important outcome of the paper is the analysis of the evolution in quality of comparisons since a previously reported one. At the RML level, the improvements are: demonstration of the international equivalence of primary Romanian activity standard, improvement of the secondary standard, relevance of the comparison within the IAEA frame, implementation of a quality system in standardization and in comparisons, and implication of the RML in calibrations and metrological checks. The participants' reported improvements refer to growing of the awareness in quality of measurement and improvement of the measurement equipment. Reasons for future comparisons organization are presented. (author)

Urotensin-II receptor is over-expressed in colon cancer cell lines and in colon carcinoma in humans.

Urotensin (U)-II receptor (UTR) has been previously reported to be over-expressed in a number of tumours. Whether UTR-related pathway plays a role in colon carcinogenesis is unknown. We evaluated UTR protein and mRNA expression in human epithelial colon cancer cell lines and in normal colon tissue, adenomatous polyps and colon cancer. U-II protein expression was assessed in cancer cell lines. Moreover, we evaluated the effects of U-II(4-11) (an UTR agonist), antagonists and knockdown of UTR protein expression through a specific shRNA, on proliferation, invasion and motility of human colon cancer cells. Cancer cell lines expressed U-II protein and UTR protein and mRNA. By immunohistochemistry, UTR was expressed in 5-30% of epithelial cells in 45 normal controls, in 30-48% in 21 adenomatous polyps and in 65-90% in 48 colon adenocarcinomas. UTR mRNA expression was increased by threefold in adenomatous polyps and eightfold in colon cancer, compared with normal colon. U-II(4-11) induced a 20-40% increase in cell growth while the blockade of the receptor with specific antagonists caused growth inhibition of 20-40%. Moreover, the knock down of UTR with a shRNA or the inhibition of UTR with the antagonist urantide induced an approximately 50% inhibition of both motility and invasion. UTR appears to be involved in the regulation of colon cancer cell invasion and motility. These data suggest that UTR-related pathway may play a role in colon carcinogenesis and that UTR may function as a target for therapeutic intervention in colon cancer. © 2013 Stichting European Society for Clinical Investigation Journal Foundation.

Colonic necrosis has been reported after sodium polystyrene sulfonate (SPS)/sorbitol use, but the incidence and relative risk (RR) are not established. Retrospective cohort study. 123,391 adult inpatients at a tertiary medical center. Receipt of SPS prescriptions (exposed) or a prescription other than SPS (unexposed internal comparison group) between September 1, 2001, and October 31, 2010. The main outcome measure was tissue-confirmed diagnosis of colonic necrosis, considered SPS-associated if SPS was prescribed 30 or fewer days before tissue accession date. Demographics, serum chemistry test results, hospital location, and International Classification of Diseases, Ninth Revision diagnostic codes. SPS was prescribed to 2,194 inpatients. 82 inpatient colonic necrosis cases were identified. 3 received oral SPS (1 gram per 4 milliliters of 33% sorbitol) 30 or fewer days before the colonic necrosis accession date (3.7% of inpatient colonic necrosis cases). The data were linked with 123,391 individuals who received inpatient prescriptions between the same dates. Colonic necrosis incidence was 0.14% (95% CI, 0.03%-0.40%) in those prescribed SPS versus 0.07% (95% CI, 0.05-0.08%) in those not prescribed SPS (RR, 2.10; 95% CI, 0.68-6.48; P = 0.2). The number needed to harm was 1,395 (95% CI, 298-5,100). Subgroup analysis (age >65 years; estimated glomerular filtration rate, sorbitol prescription was not associated significantly with an increased RR of colonic necrosis in this retrospective cohort analysis.

Full Text Available Background. Situs inversus viscerum totalis (reciprocally reversed position of internal organs is a rare case with genetic predisposition, inherited autosomnously recessive. The presented case involves an older patient with complete transposition of internal organs having acute calculous cholecystitis, which was successfully performed the laparoscopic cholecystectomy. Whilst the production of biliary stones in a case of transposed internal organs is very rare, it may well represent a diagnostic problem. It is not, however, the contraindication for laparoscopic surgery.Patients and methods. The case presents a 64-year-old patient, whose persistent biliary colic trouble eventually resulted in acute cholecystitis. Following routine diagnostics, a laparoscopic cholecystectomy was performed and the patient was released in domestic care after three day hospitalization.Conclusions. The laparoscopic cholecystectomy may also be safely performed in a patient with reciprocal transposition of all internal organs, but it is imperative to consider the fact that the extra-hepatic anatomy of gall bladder and vascular system is the mirror image of normal, right-hand positioned liver.

Colonization Habitat Controls Biomass, Composition, and Metabolic Activity of Attached Microbial Communities in the Columbia River Hyporheic Corridor

Hydrologic exchange plays a critical role in biogeochemical cycling within the hyporheic zone (the interface between river water and groundwater) of riverine ecosystems. Such exchange may set limits on the rates of microbial metabolism and impose deterministic selection on microbial communities that adapt to dynamically changing dissolved organic carbon (DOC) sources. This study examined the response of attached microbial communities (in situcolonized sand packs) from groundwater, hyporheic, and riverbed habitats within the Columbia River hyporheic corridor to “cross-feeding” with either groundwater, river water, or DOC-free artificial fluids. Our working hypothesis was that deterministic selection duringin situcolonization would dictate the response to cross-feeding, with communities displaying maximal biomass and respiration when supplied with their native fluid source. In contrast to expectations, the major observation was that the riverbed colonized sand had much higher biomass and respiratory activity, as well as a distinct community structure, compared with those of the hyporheic and groundwater colonized sands. 16S rRNA gene amplicon sequencing revealed a much higher proportion of certain heterotrophic taxa as well as significant numbers of eukaryotic algal chloroplasts in the riverbed colonized sand. Significant quantities of DOC were released from riverbed sediment and colonized sand, and separate experiments showed that the released DOC stimulated respiration in the groundwater and piezometer colonized sand. These results suggest that the accumulation and degradation of labile particulate organic carbon (POC) within the riverbed are likely to release DOC, which may enter the hyporheic corridor during hydrologic exchange, thereby stimulating microbial activity and imposing deterministic selective pressure on the microbial community composition.

Strategies For Human Exploration Leading To Human Colonization of Space

Smitherman, David; Everett, Harmon

2009-01-01

Enabling the commercial development of space is key to the future colonization of space and key to a viable space exploration program. Without commercial development following in the footsteps of exploration it is difficult to justify and maintain public interest in the efforts. NASA's exploration program has suffered from the lack of a good commercial economic strategy for decades. Only small advances in commercial space have moved forward, and only up to Earth orbit with the commercial satellite industry. A way to move beyond this phase is to begin the establishment of human commercial activities in space in partnership with the human exploration program. In 2007 and 2008, the authors researched scenarios to make space exploration and commercial space development more feasible as part of their graduate work in the Space Architecture Program at the Sasakawa International Center for Space Architecture at the University of Houston, Houston, Texas. Through this research it became apparent that the problems facing future colonization are much larger than the technology being developed or the international missions that our space agencies are pursuing. These issues are addressed in this paper with recommendations for space exploration, commercial development, and space policy that are needed to form a strategic plan for human expansion into space. In conclusion, the authors found that the current direction in space as carried out by our space agencies around the world is definitely needed, but is inadequate and incapable of resolving all of the issues that inhibit commercial space development. A bolder vision with strategic planning designed to grow infrastructures and set up a legal framework for commercial markets will go a long way toward enabling the future colonization of space.

International Non-Governmental Organizations in Latin America and Social Capital

Full Text Available International Non-Governmental Organizations (INGOs in developing countries promote interests of the poor, provide social services, and stimulate community engagement. The exponential growth of INGOs during the last four decades was accompanied by major financial scandals and corruption charges leading to an increase in research on the impact of INGOs on community well-being in developing countries. Due to sparse empirical studies that evaluate the role and functions of INGOs, the question of the impact of INGOs on community well-being has remained largely rhetorical. Our study attempts to provide preliminary evidence on the impact of socio-economic programs carried out by an International Governmental Organization (INGO, Adventist Development and Relief Agency (ADRA, in four Latin American countries. Results from the quasi-experimental study suggest that communities with ADRA programs have a higher level of social capital than communities without them. While the results reported here may not be generalized to all INGOs, our study is unique in providing a valuable empirical approach toward examining the role of INGOs in developing countries.

Unique Organization of Extracellular Amylases into Amylosomes in the Resistant Starch-Utilizing Human Colonic Firmicutes Bacterium Ruminococcus bromii.

Ruminococcus bromii is a dominant member of the human gut microbiota that plays a key role in releasing energy from dietary starches that escape digestion by host enzymes via its exceptional activity against particulate "resistant" starches. Genomic analysis of R. bromii shows that it is highly specialized, with 15 of its 21 glycoside hydrolases belonging to one family (GH13). We found that amylase activity in R. bromii is expressed constitutively, with the activity seen during growth with fructose as an energy source being similar to that seen with starch as an energy source. Six GH13 amylases that carry signal peptides were detected by proteomic analysis in R. bromii cultures. Four of these enzymes are among 26 R. bromii proteins predicted to carry dockerin modules, with one, Amy4, also carrying a cohesin module. Since cohesin-dockerin interactions are known to mediate the formation of protein complexes in cellulolytic ruminococci, the binding interactions of four cohesins and 11 dockerins from R. bromii were investigated after overexpressing them as recombinant fusion proteins. Dockerins possessed by the enzymes Amy4 and Amy9 are predicted to bind a cohesin present in protein scaffoldin 2 (Sca2), which resembles the ScaE cell wall-anchoring protein of a cellulolytic relative, R. flavefaciens. Further complexes are predicted between the dockerin-carrying amylases Amy4, Amy9, Amy10, and Amy12 and two other cohesin-carrying proteins, while Amy4 has the ability to autoaggregate, as its dockerin can recognize its own cohesin. This organization of starch-degrading enzymes is unprecedented and provides the first example of cohesin-dockerin interactions being involved in an amylolytic system, which we refer to as an "amylosome." Fermentation of dietary nondigestible carbohydrates by the human colonic microbiota supplies much of the energy that supports microbial growth in the intestine. This activity has important consequences for health via modulation of

Ancient lineage, young troglobites: recent colonization of caves by Nesticella spiders.

Science.gov (United States)

Zhang, Yuanyuan; Li, Shuqiang

2013-09-04

The evolution and origin of cave organisms is a recurring issue in evolutionary studies, but analyses are often hindered by the inaccessibility of caves, morphological convergence, and complex colonization processes. Here we investigated the evolutionary history of Nesticella cave spiders, which are mainly distributed in the Yunnan-Guizhou Plateau, China. With comprehensive sampling and phylogenetic and coalescent-based analyses, we investigated the tempo and mode of diversification and the origins of these troglobites. We also aimed to determine which factors have influenced the diversification of this little-known group. Coalescent-based species delimitation validated the 18 species recognized by morphological inspection and also suggested the existence of cryptic lineages. Divergence time estimates suggested that Nesticella cave spiders in the Yunnan-Guizhou Plateau constituted a monophyletic troglobite clade that originated in the middle Miocene (11.1-18.6 Ma). Although the Yunnan-Guizhou Plateau clade was composed exclusively of troglobite species, suggesting an ancient common subterranean ancestor, we favor multiple, independent cave colonizations during the Pleistocene over a single ancient cave colonization event to explain the origin of these cave faunas. The diversification of plateau Nesticella has been greatly influenced by the sequential uplift of the plateau and likely reflects multiple cave colonizations over time by epigean ancestors during Pleistocene glacial advances. We concluded that plateau cave Nesticella represent an ancient group of spiders, but with young troglobite lineages that invaded caves only recently. The absence of extant epigean relatives and nearly complete isolation among caves supported their relict status. Our work highlights the importance of comprehensive sampling for studies of subterranean diversity and the evolution of cave organisms. The existence of potentially cryptic species and the relict status of Nesticella

Canan Ceran

2013-01-01

Full Text Available OBJECTIVES: In addition to its roles in the stimulation of growth hormone secretion and the regulation of appetite and metabolism, ghrelin exerts immunomodulatory, anti-inflammatory and antioxidant actions in several organ systems. In this study, we investigated the effects of ghrelin on the healing of experimental colonic anastomoses. METHODS: Wistar rats were randomly divided into two groups (n = 10 in each. A segment of colon was excised, and an end-to-end anastomosis was performed in the distal colon. The Ghrelin Group received 10 ng/kg/day IP ghrelin for seven days postoperatively, whereas the Control Group received an identical volume of saline. On the seventh postoperative day, the anastomotic bursting pressures and hydroxyproline levels were measured, and adhesion formation around the anastomoses was examined. Histopathological analyses were performed to evaluate inflammatory cell infiltration, fibroblast infiltration, collagen density and neovascularization. RESULTS: In the Ghrelin Group, the bursting pressure and hydroxyproline levels were significantly higher than in the Control Group. The adhesion formation scores were lower in the Ghrelin Group than in the Control Group. Although the inflammatory cell infiltration was diminished in the Ghrelin Group, the degrees of fibroblast infiltration, collagen density and neovascularization were not significantly different between the groups. CONCLUSION: Our results indicate that ghrelin improves the healing of colonic anastomoses in rats.

Human wound colonization by Lucilia eximia and Chrysomya rufifacies (Diptera: Calliphoridae): myiasis, perimortem, or postmortem colonization?

Science.gov (United States)

Sanford, Michelle R; Whitworth, Terry L; Phatak, Darshan R

2014-05-01

The infestation of human or animal tissues by fly larvae has been given distinctive terminology depending on the timing and location of colonization. Wounds and orifices colonized by Diptera in a living human or animal are typically referred to as myiasis. When the colonization occurs after death, it is referred to as postmortem colonization and can be used to estimate the minimum postmortem interval. What happens when the human, as in the case presented here, has a necrotic limb while the human remains alive, at least for a short period of time? The case presented here documents perimortem wound colonization by Lucilia eximia (Wiedemann) and Chrysomya rufifacies (Macquart) and the considerations for approximating development temperatures and estimating the time of colonization (TOC). This represents the first record of L. eximia in human myiasis in the United States and the first record of the co-occurrence of L. eximia and C. rufifacies in human myiasis in the United States. The TOC was estimated using both ambient and body temperature. Insect colonization before death complicates the estimation of TOC and minimum postmortem interval and illustrates the problem of temperature approximation in forensic entomology casework.

RESHAPING ORGANIZATIONS – MANAGING PEOPLE THROUGH HR STRATEGIES AND INTERNAL MARKETING

Directory of Open Access Journals (Sweden)

Roxana Cioclov

2014-10-01

Full Text Available The following paper aims at presenting key concepts in regard to the interconnectivity between two similar and frequently confused practices – Human Resource Management and Internal Marketing. Therefore, it is intend to present both fields distinctively, in order to emphasise in the end the added value of the two working together. Given the fact that, in the specialised literature, there are different approaches on this subject and many questions raised regarding the separation of the instruments and particular objectives of the two practices, the paper presents a simplified approach on the HRM Cycle in comparison with the IM Cycle. Therefore, the paper is structured as follows: (1 HRM’s impact on the general activity of an organization – whether it is a manufacturing company or a service provider; (2 IM’s impact on the internal and external environment of the organization; (3 Analysis on the connection and in-/inter-/dependency of the two concepts and their meaning. Although HRM seems to bring numerous advantages to the organization, the current paper states that HR cannot be done at the same efficiency level in the absence of good Internal Marketing practices that allow the word - of - mouth to spread between the present and possible future employees. It is about a good branding that has to exceed the company’s geographical boundaries and to create the need, not only in terms of product consumer’s behavior, but also in regard to employees that want to be part of the brand.

Hirschsprung disease (HD) is a functional obstruction of the bowel caused by the absence of intrinsic enteric ganglion cells. The diagnosis of total colonic HD (TCHD) based on contrast enemas is difficult in newborns because radiological findings vary. To evaluate the radiographic and contrast enema findings in patients with pathologically proven TCHD. From 1966 to 2007, 17 records from a total of 31 patients with TCHD were retrospectively evaluated for diameter and shape of the colon, diameter of the small bowel, bowel wall contour, ileal reflux, abdominal calcifications, pneumoperitoneum, filling defects, transitional zones and rectosigmoid index. Three colonic patterns of TCHD were found: microcolon, question-mark-shape colon and normal caliber colon. Additional findings included spasmodic colon, ileal reflux, delayed evacuation and abdominal calcifications. Colonic transitional zones were found in eight patients with TCHD. The diagnosis of TCHD is difficult to establish by contrast enema studies. The length of the aganglionic small bowel and the age of the patient can influence the radiological findings in TCHD. The transitional zone and the rectosigmoid index can be false-positive in TCHD. The colon can appear normal. Consider TCHD if the contrast enema study is normal but the patient remains symptomatic and other causes of distal bowel obstruction have been excluded. (orig.)

Mutualistic interaction between Salmonella enterica and Aspergillus niger and its effects on Zea mays colonization.

Science.gov (United States)

Balbontín, Roberto; Vlamakis, Hera; Kolter, Roberto

2014-11-01

Salmonella Typhimurium inhabits a variety of environments and is able to infect a broad range of hosts. Throughout its life cycle, some hosts can act as intermediates in the path to the infection of others. Aspergillus niger is a ubiquitous fungus that can often be found in soil or associated to plants and microbial consortia. Recently, S. Typhimurium was shown to establish biofilms on the hyphae of A. niger. In this work, we have found that this interaction is stable for weeks without a noticeable negative effect on either organism. Indeed, bacterial growth is promoted upon the establishment of the interaction. Moreover, bacterial biofilms protect the fungus from external insults such as the effects of the anti-fungal agent cycloheximide. Thus, the Salmonella-Aspergillus interaction can be defined as mutualistic. A tripartite gnotobiotic system involving the bacterium, the fungus and a plant revealed that co-colonization has a greater negative effect on plant growth than colonization by either organism in dividually. Strikingly, co-colonization also causes a reduction in plant invasion by S. Typhimurium. This work demonstrates that S. Typhimurium and A. niger establish a mutualistic interaction that alters bacterial colonization of plants and affects plant physiology. © 2014 The Authors.

Thyroid gland is one of the most vascularized organs of the body, nevertheless clinical and surgical series report an incidence of secondary malignancies in this gland of only 3%. Colorectal carcinoma metastatic to the thyroid gland is not as uncommon as previously believed, infact the number of cases seems to be increased in recent years due to the more frequent use of fine-needle aspiration cytology (FNAC) guided by ultrasonography. Although kidney, breast and lung metastases to the thyroid are frequent, metastasis from colon cancer is clinically rare with 52 cases reported in the literature in the last 5 decades and three cases described as solitary thyroid metastasis from the colon cancer without any other visceral metastases. To the best of our knowledge, we report the fourth case of solitary, asymptomatic thyroid metastasis from colon cancer without involvement of other organs. We discuss the importance of FNAC to detect metastatazing process as a compulsory step of the diagnostic and therapeutic management algorithm, combined with a molecular biology approach. A review of the last 5 decades literature, to update the number of cases described to date, is also included.

The management of colon injuries has steadily evolved over the course of the last half century. So too has the management of renal trauma. It is not clear from the literature as to whether concomitant colon and renal injuries carry increased risk of morbidity and mortality, and whether this combination of injuries necessitates a specifically tailored management approach. A retrospective review was carried out for the period January 2012 to December 2016. All patients over the age of 18 years who were subjected to laparotomy for penetrating trauma (gunshot wounds or stab wounds) and who sustained an intra-operatively proven colonic injury were included in this study. Operative management and outcomes were investigated. A direct comparison was made between patients with a combined colonic and renal injury and those with only a colonic injury. Over the five-year period a total of 268 patients sustained a colonic injury. The 239 patients with a colonic injury (Group A) were compared to the 29 patients with a combined colonic and renal injury (Group B). Regarding the management of the colonic injuries, there were no differences in the rates of primary repair, anastomosis, exteriorization, or damage control surgery between groups A and B. As for the management of the renal injury, 14 were not explored at laparotomy; in 12 a nephrectomy was performed and in 3 the renal injury was repaired. The nephrectomy cohort were more likely to have undergone damage control surgery, to be admitted to ICU, to receive a colostomy, and had higher mortality. While there was no difference in the need for damage control surgery or mortality between groups, Group B had a significantly greater need for ICU admission. Morbidity was similar between the two groups - in particular, there was no difference in the rates of either gastro-intestinal complications or acute kidney injury between the two groups. In patients with combined colon and renal injuries, it seems reasonable to treat each organ

Woo, Seong Ku; Lim, Jae Hoon; Kim, Soon Yong; Ahn, Chi Yul

1982-01-01

Necrotizing colitis associated with carcinoma of the colon, known also as obstructive colitis, is a disorder characterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especially carcinoma of the rectosigmoid colon, and in rare instance, leads to acute gangrene of the colon. The authors analyzed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Barium enema disclosed mucosal edema, nodular filling defects, irregularity of the colonic contour and typical thumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism of necrotizing colitis was briefly reviewed

The necessity of strengthening the cooperation between tissue banks and organ transplant organizations at national, regional, and international levels.

Science.gov (United States)

Morales Pedraza, Jorge

2013-12-01

The donation of tissues and organs increases significantly when tissue banks and organ transplant organizations work together in the procurement of organs and tissues at donor sources (hospitals, coroners system, organ procurement agencies, and funeral homes, among others). To achieve this important goal, national competent health authorities should considered the establishment of a mechanism that promote the widest possible cooperation between tissue banks and organ transplant organizations with hospitals, research medical institutions, universities, and other medical institutions and facilities. One of the issues that can facilitate this cooperation is the establishment of a coding and traceability system that could identify all tissues and organs used in transplant activities carried out in any country. The promotion of national, regional, and international cooperation between tissue banks and organ transplant organizations would enable the sharing of relevant information that could be important for medical practice and scientific studies carried out by many countries, particularly for those countries with a weak health care system.

Reducing Campylobacter jejuni colonization of poultry via vaccination.

Directory of Open Access Journals (Sweden)

Jason M Neal-McKinney

Full Text Available Campylobacter jejuni is a leading bacterial cause of human gastrointestinal disease worldwide. While C. jejuni is a commensal organism in chickens, case-studies have demonstrated a link between infection with C. jejuni and the consumption of foods that have been cross-contaminated with raw or undercooked poultry. We hypothesized that vaccination of chickens with C. jejuni surface-exposed colonization proteins (SECPs would reduce the ability of C. jejuni to colonize chickens, thereby reducing the contamination of poultry products at the retail level and potentially providing a safer food product for consumers. To test our hypothesis, we injected chickens with recombinant C. jejuni peptides from CadF, FlaA, FlpA, CmeC, and a CadF-FlaA-FlpA fusion protein. Seven days following challenge, chickens were necropsied and cecal contents were serially diluted and plated to determine the number of C. jejuni per gram of material. The sera from the chickens were also analyzed to determine the concentration and specificity of antibodies reactive against the C. jejuni SECPs. Vaccination of chickens with the CadF, FlaA, and FlpA peptides resulted in a reduction in the number of C. jejuni in the ceca compared to the non-vaccinated C. jejuni-challenged group. The greatest reduction in C. jejuni colonization was observed in chickens injected with the FlaA, FlpA, or CadF-FlaA-FlpA fusion proteins. Vaccination of chickens with different SECPs resulted in the production of C. jejuni-specific IgY antibodies. In summary, we show that the vaccination of poultry with individual C. jejuni SECPs or a combination of SECPs provides protection of chickens from C. jejuni colonization.

Full Text Available Many plant-associated organisms, including microbes, nematodes, and insects, deliver effector proteins into the apoplast, vascular tissue, or cell cytoplasm of their prospective hosts. These effectors function to promote colonization, typically by altering host physiology or by modulating host immune responses. The same effectors however, can also trigger host immunity in the presence of cognate host immune receptor proteins, and thus prevent colonization. To circumvent effector-triggered immunity, or to further enhance host colonization, plant-associated organisms often rely on adaptive effector evolution. In recent years, it has become increasingly apparent that several effectors of plant-associated organisms are repeat-containing proteins (RCPs that carry tandem or non-tandem arrays of an amino acid sequence or structural motif. In this review, we highlight the diverse roles that these repeat domains play in RCP effector function. We also draw attention to the potential role of these repeat domains in adaptive evolution with regards to RCP effector function and the evasion of effector-triggered immunity. The aim of this review is to increase the profile of RCP effectors from plant-associated organisms.

Staff Association

2016-01-01

Every year in autumn, a two-day CSAIO (Conference of Staff Associations of International Organizations) conference is organized for staff associations of international organizations based mainly in Europe, as well as European agencies. Creation, objectives and progress CSAIO, created by the staff associations of CERN and OECD in 2000, invites about 30 staff associations to share their experiences and ideas to better identify the expectations and aspirations of a personnel evolving at the heart of international and European organizations. Over time, the preparation of the conference has evolved to better accommodate the requests of the staff representatives coming from different horizons. For two years, there has been an initiative to institutionalize the informal follow-up, during the first half-day of the conference, of themes discussed the previous year. This follow-up allows participants to share their experience on the implementation and impacts of certain propositions as reflected in their organizations ...

The aim of this study is to assess the short-term outcome of intraoperative colonic irrigation and primary anastomosis and to suggest the usefulness of the procedure when a preoperative mechanical bowel preparation is inappropriate. This retrospective study included 38 consecutive patients (19 male patients) who underwent intraoperative colonic irrigation and primary anastomosis for left colon disease between January 2010 and December 2016. The medical records of the patients were reviewed to evaluate the patients' characteristics, operative data, and postoperative short-term outcomes. Twenty-nine patients had colorectal cancer, 7 patients had perforated diverticulitis, and the remaining 2 patients included 1 with sigmoid volvulus and 1 with a perforated colon due to focal colonic ischemia. A diverting loop ileostomy was created in 4 patients who underwent a low anterior resection. Complications occurred in 15 patients (39.5%), and the majority was superficial surgical site infections (18.4%). Anastomotic leakage occurred in one patient (2.6%) who underwent an anterior resection due sigmoid colon cancer with obstruction. No significant difference in overall postoperative complications and superficial surgical site infections between patients with obstruction and those with peritonitis were noted. No mortality occurred during the first 30 postoperative days. The median hospital stay after surgery was 15 days (range, 8-39 days). Intraoperative colonic irrigation and primary anastomosis seem safe and feasible in selected patients. This procedure may reduce the burden of colostomy in patients requiring a left colon resection with an inappropriate preoperative mechanical bowel preparation.

Genes Contributing to Porphyromonas gingivalis Fitness in Abscess and Epithelial Cell Colonization Environments

Full Text Available Porphyromonas gingivalis is an important cause of serious periodontal diseases, and is emerging as a pathogen in several systemic conditions including some forms of cancer. Initial colonization by P. gingivalis involves interaction with gingival epithelial cells, and the organism can also access host tissues and spread haematogenously. To better understand the mechanisms underlying these properties, we utilized a highly saturated transposon insertion library of P. gingivalis, and assessed the fitness of mutants during epithelial cell colonization and survival in a murine abscess model by high-throughput sequencing (Tn-Seq. Transposon insertions in many genes previously suspected as contributing to virulence showed significant fitness defects in both screening assays. In addition, a number of genes not previously associated with P. gingivalis virulence were identified as important for fitness. We further examined fitness defects of four such genes by generating defined mutations. Genes encoding a carbamoyl phosphate synthetase, a replication-associated recombination protein, a nitrosative stress responsive HcpR transcription regulator, and RNase Z, a zinc phosphodiesterase, showed a fitness phenotype in epithelial cell colonization and in a competitive abscess infection. This study verifies the importance of several well-characterized putative virulence factors of P. gingivalis and identifies novel fitness determinants of the organism.

Microbial colonization of prepainted steel, commonly used in roofing applications, impacts their aesthetics, durability, and functionality. Understanding the relevant organisms and the mechanisms by which colonization occurs would provide valuable information that can be subsequently used to design fouling prevention strategies. Here, next-generation sequencing and microbial community finger printing (T-RFLP) were used to study the community composition of microbes colonizing prepainted steel roofing materials at Burrawang, Australia and Kapar, Malaysia over a 52-week period. Community diversity was low and was dominated by Bacillus spp., cyanobacteria, actinobacteria, Cladosporium sp., Epicoccum nigrum, and Teratosphaeriaceae sp. Cultivation-based methods isolated approximately 20 different fungi and bacteria, some of which, such as E. nigrum and Cladosporium sp., were represented in the community sequence data. Fluorescence in situ hybridization imaging showed that fungi were the most dominant organisms present. Analysis of the sequence and T-RFLP data indicated that the microbial communities differed significantly between locations and changed significantly over time. The study demonstrates the utility of molecular ecology tools to identify and characterize microbial communities associated with the fouling of painted steel surfaces and ultimately can enable the targeted development of control strategies based on the dominant species responsible for fouling. © 2016 The Authors.

Terrorism is a huge public hazard of the international community. Alliances of terrorist organizations may cause more serious threat to national security and world peace. Understanding alliances between global terrorist organizations will facilitate more effective anti-terrorism collaboration between governments. Based on publicly available data, this study constructed a alliance network between terrorist organizations and analyzed the alliance relationships with link prediction. We proposed a novel index based on optimal weighted fusion of six similarity indices, in which the optimal weight is calculated by genetic algorithm. Our experimental results showed that this algorithm could achieve better results on the networks than other algorithms. Using this method, we successfully digged out 21 real terrorist organizations alliance from current data. Our experiment shows that this approach used for terrorist organizations alliance mining is effective and this study is expected to benefit the form of a more powerful anti-terrorism strategy.

The radiological correlate to the pseudo-obstruction of the colon is not specific, but it does supply a pointer to the disease of it shows dilation of the caecum, colon ascendens and colon transversum with air-pockets and reflected imaging as well as a usually not dilated colon descendens with remarkably little air. To make the diagnosis quite sure we must exclude intestinal obstruction by using X-ray contrast media or by coloscopy. (orig./GDG) [de

Internal structures of self-organized relaxed states and self-similar decay phase

Kondoh, Yoshiomi

1992-03-01

A thought analysis on relaxation due to nonlinear processes is presented to lead to a set of general thoughts applicable to general nonlinear dynamical systems for finding out internal structures of the self-organized relaxed state without using 'invariant'. Three applications of the set of general thoughts to energy relaxations in resistive MHD plasmas, incompressible viscous fluids, and incompressible viscous MHD fluids are shown to lead to the internal structures of the self-organized relaxed states. It is shown that all of the relaxed states in these three dynamical systems are followed by self-similar decay phase without significant change of the spatial structure. The well known relaxed state of ∇ x B = ±λ B is shown to be derived generally in the low β plasma limit. (author)

Radiolabelled enema solution was administered to eight healthy subjects, both in fasted and fed states. Enema spreading was monitored over a 4-h period using gamma scintigraphy and colonic motility was recorded simultaneously using a pressure sensitive radiotelemetry capsule. The rate and extent of enema dispersion were unaffected by eating. Spreading could be correlated with colonic motility and was inhibited by aboral propulsion of the colonic contents. (orig.)

Primary repair of colon injuries is an accepted therapeutic option; however, controversy persists regarding its safety. Our objective was to report the evolution and presence of complications in patients with colon injury who underwent primary closure and to determine if the time interval (>6 h), degree of injury, contamination, anatomic site injured, PATI (Penetrating Abdominal Trauma Index) >25, and the presence of other injuries in colon trauma are associated with increased morbidity and mortality. This was a prospective, observational, longitudinal and descriptive study conducted at the Central Hospital "Dr. Ignacio Morones Prieto," San Luis Potosí, Mexico, from January 1, 2003 to December 31, 2007. We included patients with abdominal trauma with colon injury subjected to surgical treatment. chi(2) was used for basic statistical analysis. There were 481 patients with abdominal trauma who underwent surgery; 77(16.1%) had colon injury. Ninety percent (n = 69) were treated in the first 6 h; 91% (n = 70) were due to penetrating injuries, and gunshot wound accounted for 48% (n = 37). Transverse colon was the most frequently injured (38%) (n = 29). Grade I and II injuries accounted for 75.3% (n = 58). Procedures included primary repair (76.66 %) (n = 46); resection with anastomosis (8.3%) (n = 5); and colostomy (15%) (n = 9). Associated injuries were present in 76.6% (n = 59). There was some degree of contamination in 85.7% (n = 66); 82.8% (58) had PATI colon injury. Primary repair is a safe procedure for treatment of colon injuries. Patients with primary repair had lower morbidity (p <0.009). Surgery during the first 6 h (p <0.006) and in hemodynamically stable patients (p <0.014) had a lower risk of complications.

Bacterial colonization of colonic crypt mucous gel and disease activity in ulcerative colitis.

LENUS (Irish Health Repository)

Rowan, Fiachra

2012-02-01

OBJECTIVE: To optimize total bacterial 16S rRNA quantification in microdissected colonic crypts in healthy controls and patients with ulcerative colitis (UC) and to characterize the findings with disease activity. BACKGROUND: Microscopic and molecular techniques have recently converged to allow bacterial enumeration in remote anatomic locations [eg, crypt-associated mucous gel (CAMG)]. The aims of this study were to combine laser capture microdissection (LCM) and 16S rRNA-based quantitative polymerase chain reaction (qPCR) to determine total bacterial copy number in CAMG both in health and in UC and to characterize the findings with disease activity. METHODS: LCM was used to microdissect CAMG from colonic mucosal biopsies from controls (n = 20) and patients with acute (n = 10) or subacute (n = 10) UC. Pan-bacterial 16S rRNA copy number per millimeter square in samples from 6 locations across the large bowel was obtained by qPCR using Desulfovibrio desulfuricans as a reference strain. Copy numbers were correlated with the UC disease activity index (UCDAI) and the simple clinical colitis activity index (SCCAI). RESULTS: Bacterial colonization of CAMG was detectable in all groups. Copy numbers were significantly reduced in acute UC. In subacute colitis, there was a positive correlation between copy number and UCDAI and SCCAI in the ascending, transverse and sigmoid colon. CONCLUSIONS: This study describes a sensitive method of quantitatively assessing bacterial colonization of the colonic CAMG. A positive correlation was found between CAMG bacterial load and subacute disease activity in UC, whereas detectable bacterial load was reduced in acute UC.

Multidetector CT of the colon

Luboldt, W.; Hoepffner, N.; Holzer, K.

2003-01-01

Multidetector technology, enabling faster imaging, higher spatial resolution and reduction in radiation dose, increases the role of CT in colonic diagnostic. The higher spatial resolution in the z-direction also changes the way to analyze the images. Instead of reading axial sections, now the colon can be systematically assessed in 3D by scrolling through multiplanar reconstructions or in CT colonography by virtual endoscopy. With ongoing improvements in computer-aided diagnosis CT colonography becomes an alternative to fiberoptic colonocopy for screening (http://www.multiorganscreening.org). In this article we propose a CT examination protocol for the colon, describe the typical imaging findings of different colonic diseases, and summarize the current status of CT colonography. (orig.)

Joint radiation emergency management plan of the international organizations. Emergency preparedness and response. Date effective: 1 January 2007

2007-01-01

The Convention on Early Notification of a Nuclear Accident (the 'Early Notification Convention') and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (the 'Assistance Convention') are the prime legal instruments that establish an international framework to facilitate the exchange of information and the prompt provision of assistance in the event of a nuclear accident or radiological emergency, with the aim of minimizing the consequences. The International Atomic Energy Agency (IAEA) has specific functions assigned to it under these Conventions, to which, in addition to a number of States, the European Union (EURATOM), the World Health Organization (WHO), the World Meteorological Organization (WMO) and the Food and Agriculture Organization of the United Nations (FAO) are full Parties. Since 1989, the arrangements between these organizations for facilitating the practical implementation of those articles of the two Conventions that are operational in nature have been documented by the IAEA in the Emergency Notification and Assistance Technical Operations Manual (ENATOM)1. The manual is intended for use primarily by contact points as identified in the Conventions. Pursuant to the obligations placed on it by the Conventions, the IAEA regularly convenes the Inter-Agency Committee on Response to Nuclear Accidents (IACRNA)2, whose purpose is to co-ordinate the arrangements of the relevant international intergovernmental organizations ('international organizations') for preparing for and responding to nuclear or radiological emergencies. Although the Conventions assign specific response functions and responsibilities to the IAEA and the Parties, various international organizations have - by virtue of their statutory functions or of related legal instruments - general functions and responsibilities that encompass aspects of preparedness and response. Moreover, some regional organizations (e.g. the European Union) are party to legally

2016-01-01

To describe the incidence and mortality rates from colon and rectal cancer in Midwestern Brazil. Data for the incidence rates were obtained from the Population-Based Cancer Registry (PBCR) according to the available period. Mortality data were obtained from the Mortality Information System (SIM) for the period between 1996 and 2008. Incidence and mortality rates were calculated by gender and age groups. Mortality trends were analyzed by the Joinpoint software. The age-period-cohort effects were calculated by the R software. The incidence rates for colon cancer vary from 4.49 to 23.19/100,000, while mortality rates vary from 2.85 to 14.54/100,000. For rectal cancer, the incidence rates range from 1.25 to 11.18/100,000 and mortality rates range between 0.30 and 7.90/100,000. Colon cancer mortality trends showed an increase among males in Cuiabá, Campo Grande, and Goiania. For those aged under 50 years, the increased rate was 13.2% in Campo Grande. For those aged over 50 years, there was a significant increase in the mortality in all capitals. In Goiânia, rectal cancer mortality in males increased 7.3%. For females below 50 years of age in the city of Brasilia, there was an increase of 8.7%, while females over 50 years of age in Cuiaba showed an increase of 10%. There is limited data available on the incidence of colon and rectal cancer for the Midwest region of Brazil. Colon cancer mortality has generally increased for both genders, but similar data were not verified for rectal cancer. The findings presented herein demonstrate the necessity for organized screening programs for colon and rectal cancer in Midwestern Brazil.

Design of colon targeting drug delivery systems using natural polymeric carriers and their evaluation by gamma scintigraphy technique

International Nuclear Information System (INIS)

Soni, P.S.; Sawarkar, S.P.; Deshpande, S.G.; Bajaj, A.N.

2004-01-01

Of late, there has been a great awareness in the concept of drug targeting and delivery to a specific site (organ, tissue or cell) in the body to maximize therapeutic effect and reduce toxicity. The various approaches of site-specific drug delivery are implantable pumps, adhesive patches impregnated with drugs, vesicle enclosed drugs and drug carriers. Colonic drug delivery is intended for local and systemic treatment in the diseases of colon like inflammatory bowel conditions. Several approaches using viz. pro-drugs, biodegradable polymers and pH sensitive polymer coatings have been used to achieve colonic delivery. Natural polysaccarides like guar gum and pectin are promising candidates because they are susceptible to degradation by colonic bacteria and thus can release the entrapped drug in the colonic region. These indigenous natural polymers are cheaply and readily available. They comprise of polygalactouronic acid and refractory to host enzymes present in the upper gastrointestinal tract and are degraded by the enzymes produced by the colonic microflora. They were evaluated as a colonic carrier using 5-amino salicylic acid (5-ASA) as a model drug. After successful in vitro testing, gamma scintigraphy technique was used to assess in-vivo behavior of the colon specific drug delivery after a coat of Guar gum and Pectin

Samples of seven species of cephalopods and crustaceans were collected from major fish markets on the Korean coast and analyzed for mercury (Hg) using a direct Hg analyzer and for the metals cadmium (Cd), lead (Pb), chromium, silver, nickel, copper, and zinc using inductively coupled plasma mass spectrometry. The distributions of heavy metals in muscles, internal organs, and whole tissues were determined, and a risk assessment was conducted to provide information concerning consumer safety. The heavy metals accumulated to higher levels (P octopus (relatively large cephalopods), red snow crab, and snow crab exceeded the European Union limits. The estimated dietary intake of Cd, Pb, and Hg for each part of all species accounted for 1.73 to 130.57%, 0.03 to 0.39%, and 0.93 to 1.67%, respectively, of the provisional tolerable daily intake adopted by the Joint Food and Agriculture Organization and World Health Organization Expert Committee on Food Additives; the highest values were found in internal organs. The hazard index (HI) is recognized as a reasonable parameter for assessing the risk of heavy metal consumption associated with contaminated food. Because of the high HI (>1.0) of the internal organs of cephalopods and the maximum HI for whole tissue of 0.424, consumers eating internal organs or whole tissues of cephalopods could be at risk of high heavy metal exposure. Therefore, the internal organs of relatively large cephalopods and crabs (except blue crab) are unfit for consumption. However, consumption of flesh after removing internal organs is a suitable approach for decreasing exposure to harmful metals.

Objective: To explore the organ doses and their distributions in different projections of CT scans. Methods: The CT values were measured and the linear absorption coefficients were derived for the main organs of the anthropomorphic phantom to compare with the normal values of human beings. The radiophotoluminescent glass dosimeters were set into various tissues or organs of the phantom for mimic measurements of the organ doses undergoing the head, chest, abdomen and pelvis CT scans, respectively. Results: The tissue equivalence of the phantom used in this study was good. The brain had the largest organ dose undergoing the head CT scan. The organ doses in thyroid, breast, lung and oesophagus were relatively large in performing the chest CT scan, while the liver, stomach, colon and lung had relatively hrge organ doses in abdomen CT practice. The doses in bone surface and colon exceeded by 50 mGy in a single pelvis CT scan. Conclusions: The organ doses and their distributions largely vary with different projections of CT scans. The organ doses of colon, bone marrow,gonads and bladder are fairly large in performing pelvis CT scan, which should be paid attention in the practice. (authors)

Throat Colonization of Neonatal Nursery Staff by Ureaplasma urealyticum: an Infection Control or Occupational Health Consideration?

Directory of Open Access Journals (Sweden)

Joanne E Embree

1994-01-01

Full Text Available Very low birth weight infants often have protracted respiratory tract colonization with Ureaplasma urealyticum. To determine whether prolonged contact with very low birth weight infants resulted in higher rates of upper respiratory tract colonization with this organism for caregivers, throat swabs for U urealyticum culture were obtained from medical, nursing and other support staff working in the neonatal intensive care and level II nurseries at the Health Sciences Centre and the St Boniface Hospital in Winnipeg, Manitoba. Throat colonization by U urealyticum was demonstrated in 7.3% (95% ci 0 to 15.6% of 41 nurses working in the intensive care nurseries but in none of the 48 nurses working in other locations or the 66 other individuals tested (P=0.02. However, throat colonization was not significantly higher among the neonatal intensive care nurses than among the women delivering at one of the study institutions. Close contact with very low birth weight infants appears to constitute a minimal risk for increased throat colonization with U urealyticum among hospital staff members.

2015-01-01

Vasohibin-1 (VASH1) is an endogenous angiogenesis inhibitor. However, the clinical relevance of VASH1 in colon cancer and its regulations on cancer angiogenesis and cancer cell biological characteristics are still unknown. Here we showed that stromal VASH1 levels were negatively correlated with tumor size, advanced clinical stage and distant metastases in colon cancer patients. Overexpression of VASH1 in colon cancer cells induced apoptosis and senescence, inhibiting cancer cell growth and co...

Individualized adjustments to reference phantom internal organ dosimetry—scaling factors given knowledge of patient internal anatomy

Science.gov (United States)

Wayson, Michael B.; Bolch, Wesley E.

2018-04-01

Various computational tools are currently available that facilitate patient organ dosimetry in diagnostic nuclear medicine, yet they are typically restricted to reporting organ doses to ICRP-defined reference phantoms. The present study, while remaining computational phantom based, provides straightforward tools to adjust reference phantom organ dose for both internal photon and electron sources. A wide variety of monoenergetic specific absorbed fractions were computed using radiation transport simulations for tissue spheres of varying size and separation distance. Scaling methods were then constructed for both photon and electron self-dose and cross-dose, with data validation provided from patient-specific voxel phantom simulations, as well as via comparison to the scaling methodology given in MIRD Pamphlet No. 11. Photon and electron self-dose was found to be dependent on both radiation energy and sphere size. Photon cross-dose was found to be mostly independent of sphere size. Electron cross-dose was found to be dependent on sphere size when the spheres were in close proximity, owing to differences in electron range. The validation studies showed that this dataset was more effective than the MIRD 11 method at predicting patient-specific photon doses for at both high and low energies, but gave similar results at photon energies between 100 keV and 1 MeV. The MIRD 11 method for electron self-dose scaling was accurate for lower energies but began to break down at higher energies. The photon cross-dose scaling methodology developed in this study showed gains in accuracy of up to 9% for actual patient studies, and the electron cross-dose scaling methodology showed gains in accuracy up to 9% as well when only the bremsstrahlung component of the cross-dose was scaled. These dose scaling methods are readily available for incorporation into internal dosimetry software for diagnostic phantom-based organ dosimetry.

Ogilvie's syndrome is acute colonic dilatation without organic obstacle in a previously healthy colon. Surgery is the only treatment of cases complicated by necrosis or perforation. In contrast, treatment of uncomplicated forms is not unanimous, and is the subject of this literature review. Determine the results of different therapeutic methods of uncomplicated forms of Ogilvie's syndrome in terms of efficiency of removal of colonic distension, recurrence, morbidity and mortality. Clarify their respective indications. An electronic literature search in the "MEDLINE" database, supplemented by hand searching on the reference lists of articles, was conducted for the period between 1980 and 2012. Conservative treatment is effective in 53 to 96% of cases with a risk of colonic perforation less than 2.5% and a mortality of 0 to 14% % (level of evidence 4, recommendation grade C). Neostigmine is effective in 64 to 91% of cases after a first dose, with a risk of recurrence of 0 to 38%. It remains effective in 40 to 100% of cases after a second dose (evidence level 2, grade recommendation B). Endoscopic decompression is a safe and effective technique with a success rate of 61 to 100% at the first attempt , a recurrence rate of 0 to 50%, a rate of colonic perforation less than 5% and a mortality less than 5% (level evidence 4, recommendation grade C). PEG may be recommended for the prevention of recurrence of the ACPO after successful treatment with neostigmine or endoscopic decompression (evidence level 2, recommendation grade B). The cecostomy is more effective and safer than conventional colostomy (level of evidence 4, recommendation grade C). The cecostomy is highly effective in colonic decompression but associated with a high mortality (level of evidence 4, recommendation grade C). Conservative treatment is recommended in first intention. In case of failure, neostigmine should be tried. If unsuccessful, the endoscopic decompression is proposed. The cecostomy is

Free jejunal transfer is a common procedure for hypopharyngo-esophageal reconstruction. We reviewed our experience with patients who underwent free jejunal and colon transfer surgery for hypopharyngo-esophageal reconstruction in the last 20 years in our institute. A retrospective review was conducted for 31 cases of reconstruction with free jejunal and colon transfer performed at Japanese Red Cross Matsue Hospital during the period of 20 years from January 1992 to December 2011. The mean age of the patients was 66 years. There were 30 patients with hypopharynx cancer and one patient with larynx cancer. Thirty patients had received preoperative radiotherapy and chemotherapy. The average time of surgery for free jejunal transfer reconstruction was 8.8 hours, including extraction of the hypopharynx, pharynx and cervical esophagus, debridment of pars hemi-cervicalis, and grafting procedure of free jejunum. The most common recipient vessels were the transverse cervical artery and external jugular vein, but recently, vessels of free flaps are often chosen to be anastomosed with the superior thyroid artery and internal jugular vein. The free jejunal and colon grafts for reconstruction took successfully in all patients. The complication rate was 52% (16/31 cases). Complications often occurred in cases of total esophagectomy, recurrence after full-dose chemoradiotherapy, and radiation therapy administered postoperatively. (author)

Competition between Vibrio fischeri strains during initiation and maintenance of a light organ symbiosis.

Science.gov (United States)

Lee, K H; Ruby, E G

1994-04-01

Colonization of the light-emitting organ of the Hawaiian squid Euprymna scolopes is initiated when the nascent organ of a newly hatched squid becomes inoculated with Vibrio fischeri cells present in the ambient seawater. Although they are induced for luminescence in the light organ, these symbiotic strains are characteristically non-visibly luminous (NVL) when grown in laboratory culture. The more typical visibly luminous (VL) type of V. fischeri co-occurs in Hawaiian seawater with these NVL strains; thus, two phenotypically distinct groups of this species potentially have access to the symbiotic niche, yet only the NVL ones are found there. In laboratory inoculation experiments, VL strains, when presented in pure culture, showed the same capability for colonizing the light organ as NVL strains. However, in experiments with mixed cultures composed of both VL and NVL strains, the VL ones were unable to compete with the NVL ones and did not persist within the light organ as the symbiosis became established. In addition, NVL strains entered light organs that had already been colonized by VL strains and displaced them. The mechanism underlying the symbiotic competitiveness exhibited by NVL strains remains unknown; however, it does not appear to be due to a higher potential for siderophore activity. While a difference in luminescence phenotype between VL and NVL strains in culture is not likely to be significant in the symbiosis, it has helped identify two distinct groups of V. fischeri that express different colonization capabilities in the squid light organ. This competitive difference provides a useful indication of important traits in light organ colonization.

Stochastic resonance phenomenon was observed in organic field effect transistor using poly(3-hexylthiophene), which enhances performance of signal transmission with application of noise. The enhancement of correlation coefficient between the input and output signals was low, and the variation of correlation coefficient was not remarkable with respect to the intensity of external noise, which was due to the existence of internal additive noise following the nonlinear threshold response. In other words, internal additive noise plays a positive role on the capability of approximately constant signal transmission regardless of noise intensity, which can be said “homeostatic” behavior or “noise robustness” against external noise. Furthermore, internal additive noise causes emergence of the stochastic resonance effect even on the threshold unit without internal additive noise on which the correlation coefficient usually decreases monotonically.

Historical and Current Trends in Colon Trauma

The authors discuss the evolution of the evaluation and management of colonic trauma, as well as the debate regarding primary repair versus fecal diversion. Their evidence-based review covers diagnosis, management, surgical approaches, and perioperative care of patients with colon-related trauma. The management of traumatic colon injuries has evolved significantly over the past 50 years; here the authors describe a practical approach to the treatment and management of traumatic injuries to the colon based on the most current research. However, management of traumatic colon injuries remains a challenge and continues to be associated with significant morbidity. Familiarity with the different methods to the approach and management of colonic injuries will allow surgeons to minimize unnecessary complications and mortality. PMID:24294119

Enteric-coated epichlorohydrin crosslinked dextran microspheres containing 5-Fluorouracil (5-FU) for colon drug delivery was prepared by emulsification-crosslinking method. The formulation variables studied includes different molecular weights of dextran, volume of crosslinking agent, stirring speed, time and temperature. Dextran microspheres showed mean entrapment efficiencies ranging between 77 and 87% and mean particle size ranging between 10 and 25 µm. About 90% of drug was released from uncoated dextran microspheres within 8 h, suggesting the fast release and indicated the drug loaded in uncoated microspheres, released before they reached colon. Enteric coating (Eudragit-S-100 and Eudragit-L-100) of dextran microspheres was performed by oil-in-oil solvent evaporation method. The release study of 5-FU from coated dextran microspheres was complete retardation in simulated gastric fluid (pH 1.2) and once the coating layer of enteric polymer was dissolved at higher pH (7.4 and 6.8), a controlled release of the drug from the microspheres was observed. Further, the release of drug was found to be higher in the presence of dextranase and rat caecal contents, indicating the susceptibility of dextran microspheres to colonic enzymes. Organ distribution and pharmacokinetic study in albino rats was performed to establish the targeting potential of optimized formulation in the colon.

Colonoscopic location of a tumor can influence both the surgical procedure choice and overall treatment strategy. To determine the accuracy of colonoscopy in determining the location of colon cancer compared to surgical localization and to elucidate factors that predict discordant colon cancer localization. We conducted a retrospective cross-sectional study of colon cancers diagnosed on colonoscopy at two academic tertiary-care hospitals and two affiliated community hospitals from 2012 to 2014. Colon cancer location was obtained from the endoscopic and surgical pathology reports and characterized by colon segment. We collected data on patient demographics, tumor characteristics, endoscopic procedure characteristics, surgery planned, and surgery performed. Univariate analyses using Chi-squared test and multivariate analysis using forward stepwise logistic regression were performed to determine factors that predict discordant colon cancer localization. There were 110 colon cancer cases identified during the study period. Inaccurate endoscopic colon cancer localization was found in 29% (32/110) of cases. These included 14 cases (12.7%) that were discordant by more than one colonic segment and three cases where the presurgical planned procedure was significantly changed at the time of surgery. On univariate analyses, right-sided colon lesions were associated with increased inaccuracy (43.8 vs 24.4%, p = 0.04). On multivariate analysis, right-sided colon lesions remained independently associated with inaccuracy (OR 1.74, 95% CI 1.03-2.93, p = 0.04). Colon cancer location as determined by colonoscopy is often inaccurate, which can result in intraoperative changes to surgical management, particularly in the right colon.

Full Text Available Dietary fats are thought to be important in the etiology of colon cancer. However, the evidence linking them is inconclusive. Studies on dietary protein, cholesterol and carbohydrate and the risk of colon cancer are also inconsistent. This study examined the association between dietary intake of protein, fats, cholesterol and carbohydrates, and the risk of colon cancer. Mailed questionnaires were completed by 1731 individuals with histologically confirmed cases of colon cancer and 3097 population controls between 1994 and 1997 in seven Canadian provinces. Measurements included socio-economic status, lifestyle habits and diet. A 69-item food frequency questionnaire was used to provide data on eating habits from two years before the study. Odds ratios (OR and 95% confidence intervals (CI were computed using unconditional logistic regression. The nutrients were categorized by quartiles based on the distributions among the controls. Intake of polyunsaturated fat, trans-fat and cholesterol were significantly associated with the risk of colon cancer; the ORs for the highest quartiles were 1.36 (95% CI, 1.02–1.80, 1.37 (95% CI, 1.10–1.71 and 1.42 (95% CI, 1.10–1.84, respectively. The association was stronger with proximal colon cancer (PCC. An increased risk was also observed with increasing intake of sucrose for both proximal and distal colon cancers; the ORs for the highest quartiles were 1.67 (95% CI, 1.22–2.29 for PCC and 1.58 (95% CI, 1.18–2.10 for distal colon cancer (DCC. An elevated risk of PCC was also found with increased lactose intake. Our findings provide evidence that a diet low in fat and sucrose could reduce the risk of various colon cancers.

An unusual case of advanced synchronous colon and gastric carcinoma is described. A 36 year old female was admitted to our Department with a stenosing right colon cancer diagnosed at endoscopy which was performed for lower crampy abdominal pain and gross blood in the stool. Multiple colon polyps, distal to the tumor, were also detected. On preoperative abdominal computed tomography, a stenosing right colon cancer, without evidence of abdominal diffusion, was confirmed. At laparotomy, in addition to colon cancer, an antral gastric cancer was incidentally found. En bloc hemi gastrectomy and subtotal colectomy were performed. Digestive continuity was restored by gastrojejunal and ileosigmoid anastomoses. At histology, a poorly differentiated gastric adenocarcinoma with signet ring-cell component (pT2, pN0; stage IB) and a moderately differentiated colon adenocarcinoma with a tubulovillous component (pT3, pN1; stage III, Stage Dukes C) were revealed. Both tumors showed a low expression of p53 and c-erb2 oncoproteins. No genetic defect was identified in the APC and MMR genes. The patient is alive, without recurrence, two years after the operation

Full Text Available Security or insecurity dominates the current context of international relations. It is a situation generated by the collapse of the Eastern European communist bloc and the USSR in the late 80s and early 90s, or the resistance impact to the New World Order fueled by the negative phenomena of globalization. One of the concerns of any policymakers is to know well the power relations at global and regional levels, as from their substance they will know which are the margins of action, towards one direction or another. Therefore, it will always seek to find out who is stronger and who could take domination on the scenes of international politics. Therefore, we will briefly review the factors that make the countries Brazil, Russia, India, China and South Africa unable to defeat the global dominance of the US and its major allies, only to budge it a little. Vladimir Putin has created two organizations competing to G7 and NATO. Two summits were held in Ufa, Russian Federation: the Summit of the Organization of Shanghai Cooperation (comprised of Russia, China, Kazakhstan, Tajikistan, Uzbekistan and Kyrgyzstan and the group BRICS (Brazil, Russia, India, China and South Africa. At the summit the organization was invited Belarus president, Alexander Lukashenko, as the leader of a country member in the Eurasian Economic Union countries. The Kremlin is trying to play the leading role in these organizations, but according to the International experts, such attempts did not succeed because Moscow cannot go beyond the shadow of Beijing's de facto leader of both structures.

Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002. Materials and methods: From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study. Results: Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine. Conclusion: The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilatation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours.

Diversity and colonization levels of naturally occurring arbuscular mycorrhizal fungi (AMF) in onion roots were studied to compare organic and conventional farming systems in the Netherlands. In 2004, 20 onion fields were sampled in a balanced survey between farming systems and between two regions, namely, Zeeland and Flevoland. In 2005, nine conventional and ten organic fields were additionally surveyed in Flevoland. AMF phylotypes were identified by rDNA sequencing. All plants were colonized, with 60% for arbuscular colonization and 84% for hyphal colonization as grand means. In Zeeland, onion roots from organic fields had higher fractional colonization levels than those from conventional fields. Onion yields in conventional farming were positively correlated with colonization level. Overall, 14 AMF phylotypes were identified. The number of phylotypes per field ranged from one to six. Two phylotypes associated with the Glomus mosseae-coronatum and the G. caledonium-geosporum species complexes were the most abundant, whereas other phylotypes were infrequently found. Organic and conventional farming systems had similar number of phylotypes per field and Shannon diversity indices. A few organic and conventional fields had larger number of phylotypes, including phylotypes associated with the genera Glomus-B, Archaeospora, and Paraglomus. This suggests that farming systems as such did not influence AMF diversity, but rather specific environmental conditions or agricultural practices.

Today, because of the diversity of its applications - radiation and radionuclides for medical and biological purposes are used in more countries and in more laboratories than any other application of atomic energy. International organizations, mainly the IAEA and the WHO, have played a significant role in the spread of this nuclear technology in developing countries. There are altogether 112 member states of the Agency, about 71 of them can be classified as developing countries. Out of them, nearly 56 have some kind of nuclear medicine. By that I mean there is some medical use of radioisotopes, be it imaging, radioimmunoassay or the old thyroid uptake. In most of these countries, the personnel working in nuclear medicine has been trained abroad. Training can be as short as few weeks abroad in the form of attendance at one of the four or six week training courses offered by an international organization. Occasionally it is through a fellowship offered by the same organizations. In terms of technology and training, Nuclear Medicine, in its present form, can thus be considered a high technology imported medicine in many of these countries

Training can be as short as few weeks abroad in the form of attendance at one of the four or six week training courses offered by an international organization. Occasionally it is through a fellowship offered by the same organizations. In terms of technology and training, Nuclear Medicine, in its present form, can thus be considered a high technology imported medicine in many of these countries

BACKGROUND: Cytochrome P450 (CYP) enzymes in epithelial cells lining the alimentary tract play an important role in both the elimination and activation of (pro-)carcinogens. To estimate the role of cytochrome P450 in carcinogenesis of the colon, expression patterns and protein levels of four...... representative CYPs (CYP2C, CYP2E1, CYP3A4 and CYP3A5) were determined in colon mucosa of normal and adenomatous colonic tissue of patients with adenomas and disease-free controls. METHODS: Expression of CYP2C, CYP2E1, CYP3A4, and CYP3A5 in colon mucosa of normal and adenomatous colonic tissue of patients...... with adenoma and disease-free controls was determined by RT-PCR. Protein concentration of CYPs was determined using Western blot. RESULTS: With the exception of CYP3A5, expression of CYP mRNA was similar among groups and tissues (e.g. normal colon mucosa and adenoma). CYP3A5 mRNA expression was significantly...

Colon cancer prognosis and treatment are currently based on a classification system still showing large heterogeneity in clinical outcome, especially in TNM stages II and III. Prognostic biomarkers for metastasis risk are warranted as development of distant recurrent disease mainly accounts for the high lethality rates of colon cancer. miRNAs have been proposed as potential biomarkers for cancer. Furthermore, a verified standard for normalization of the amount of input material in PCR-based relative quantification of miRNA expression is lacking. A selection of frozen tumor specimens from two independent patient cohorts with TNM stage II-III microsatellite stable primary adenocarcinomas was used for laser capture microdissection. Next-generation sequencing was performed on small RNAs isolated from colorectal tumors from the Dutch cohort (N = 50). Differential expression analysis, comparing in metastasized and nonmetastasized tumors, identified prognostic miRNAs. Validation was performed on colon tumors from the German cohort (N = 43) using quantitative PCR (qPCR). miR25-3p and miR339-5p were identified and validated as independent prognostic markers and used to construct a multivariate nomogram for metastasis risk prediction. The nomogram showed good probability prediction in validation. In addition, we recommend combination of miR16-5p and miR26a-5p as standard for normalization in qPCR of colon cancer tissue-derived miRNA expression. In this international study, we identified and validated a miRNA classifier in primary cancers, and propose a nomogram capable of predicting metastasis risk in microsatellite stable TNM stage II-III colon cancer. In conjunction with TNM staging, by means of a nomogram, this miRNA classifier may allow for personalized treatment decisions based on individual tumor characteristics. ©2014 American Association for Cancer Research.

Grady, E.D.

1984-09-01

To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

Introduction During World War II, failure to treat penetrating colon injuries with diversion could result in court martial. Based on this wartime experience, colostomy for civilian colon wounds became the standard of care for the next 4 decades. Previous work from our institution demonstrated that primary repair was the optimal management for nondestructive colon wounds. Optimal management of destructive wounds requiring resection remains controversial. To address this issue, we performed a study that demonstrated risk factors (pre or intraoperative transfusion requirement of more than 6 units of packed red blood cells, significant comorbid diseases) that were associated with a suture line failure rate of 14%, and of whom 33% died. Based on these outcomes, a clinical pathway for management of destructive colon wounds was developed. The results of the implementation of this pathway are the focus of this report. Methods Patients with penetrating colon injury were identified from the registry of a level I trauma center over a 5-year period. Records were reviewed for demographics, injury characteristics, and outcome. Patients with nondestructive injuries underwent primary repair. Patients with destructive wounds but no comorbidities or large transfusion requirement underwent resection and anastomosis, while patients with destructive wounds and significant medical illness or transfusion requirements of more than 6 units/blood received end colostomy. The current patients (CP) were compared to the previous study (PS) to determine the impact of the clinical pathway. Outcomes examined included colon related mortality and morbidity (suture line leak and abscess). Results Over a 5.5-year period, 231 patients had penetrating colon wounds. 209 survived more 24 hours and comprise the study population. Primary repair was performed on 153 (73%) patients, and 56 patients had destructive injuries (27%). Of these, 40 (71%) had resection and anastomosis and 16 (29%) had diversion

Metastasis is the primary cause of death among patients with colon cancer. However, the number of available studies regarding oral cavity metastases from colon cancer is currently limited. We herein report an unusual case of a 60-year-old male patient who developed an oral cavity metastasis from colon cancer. A total of 12 clinical case studies reporting colon cancer metastases to the mandibular gingival region were also reviewed, with the aim to elucidate the clinical and pathological characteristics of this disease entity in order to improve clinical diagnosis and treatment. It was demonstrated that patients with oral cavity metastases from colon cancer were predominantly in the sixth or seventh decades of life. The mandible was the main site of metastatic tumors to the oral cavity, while the occurrence of gingival metastases was comparatively rare. Moreover, the diagnoses of an oral metastatic tumor and primary colon cancer were often synchronous and were frequently accompanied with metastases to other organs. Several key aspects were suggested that should be accounted for when diagnosing colon cancer patients, including focusing attention to oral symptoms when examining cancer patients, utilizing a multidisciplinary approach for differential diagnosis and utilizing postoperative pathological examination to accurately diagnose the type of tumor and optimize the efficacy of treatment.

Full Text Available Objective The aim of this study was to investigate retrorenal colon incidence in percutaneous nephrolithotomy (PNL interventions made in our clinic. Materials and Methods Clinical data of 804 PNL patients, accumulated over a 7 year period (2006-2012, was surveyed. The patient files were reviewed retrospectively, and only those who had abdominal computed tomography (CT images before PNL intervention were included in the study. In the CT images, the position of both the ascending and descending colon in relation to the right and left kidneys were evaluated. Results According to our hospital reports, 394 patients with CT images were included in the present study 27 patients (6.9% had retrorenal colon, of which 18 (4.6% were on the left side, 4 (1.0% on the right side and 5 (1.3% had bilateral retrorenal colons. Colonic perforation complication was seen only in two patients and the colonic perforation rate was 0.3%. These two cases had no CT images. Conclusions PNL, in the process of becoming the standard treatment modality, is a safe and reliable technique for renal stone treatment. Colonic injury should be taken into consideration during PNL interventions of the lower pole of the kidney (especially on the left side due to the location of retrorenal colon.

Colon cancer is one of the most common malignant diseases and a major cause of mortality in the Western world. Metastasis to lymph nodes and other gastrointestinal organs, especially to the liver and lungs, is most common and occurs in up to 25% of cancer patients when initially diagnosed. The majority of colon cancers develop from noncancerous adenomatous polyps on the lining of the colon which grow over the years to become cancerous. If detected early, the surgical resections of the growth, often in combination with chemotherapy, significantly increases life expectancy. We have shown that the enzyme N-myristoyltransferase (NMT) which carries out lipid modification of several proteins (including many of those involved in oncogenesis) is expressed at higher levels in cancerous tissues from the colon. We have also shown that in peripheral blood mononuclear cells (PBMC) and bone marrow (BM) cells collected from colon cancer patients and from azoxymethane-induced rats the expression and localization of NMT is altered. We have observed strong positivity for NMT in immunohistochemical analysis for PBMC from colon cancer patients as compared to control groups. Furthermore, in the bone marrow (BM) mononuclear cells, NMT was found to be confined to the nuclei whereas in control groups it was observed to be located in the cytoplasm. In conclusion, this strikingly differential localization offers the basis of a potential investigational tool for screening or diagnosis of individuals at risk for or suspected of having colon cancer

Colonic motility in proctalgia fugax.

Science.gov (United States)

Harvey, R F

1979-10-06

Intraluminal pressure recordings were obtained from the rectum and sigmoid colon in two patients experiencing attacks of proctalgia fugax. In each patient the pain appeared to result from contractions of the sigmoid colon, and not from spasm of the levator ani, rectal wall muscle, or anal sphincters, all of which have previously been suggested as the source of such pain. Proctalgia fugax therefore appears, at least in some patients, to be an unusual variant of the irritable bowel syndrome, in which pain is referred from the sigmoid colon to the rectum.

Full Text Available Purpose: To characterize colon and rectum walls, pericolic and perirectal spaces, using endoscopic ultrasonography miniprobes. Methods: Sixty individuals (50% males, aged 18-80, were included. Using 12 and 20 MHz endoscopic ultrasonography miniprobes, all different colon segments (ascending, transverse, descending, sigmoid and rectum were evaluated according to the number and thickness of the different layers in intestinal wall, to the presence and (largest diameter of vessels in the submucosa and of peri-intestinal nodes. Results: The 20 MHz miniprobe identified a higher number of layers than the 12 MHz miniprobe, with medians of 7 and 5 respectively (p < 0.001. The rectal wall (p = 0.001, its muscularis propria (p < 0.001 and mucosa (p = 0.01 were significantly thicker than the different segments of the colon, which had no significant differences between them. Patients aged 41-60 presented thicker colonic wall and muscularis propria in descending (p = 0.001 and p = 0.004 and rectum (p=0.01 and p=0.01. Submucosal vessels were identified in 30% of individuals in descending and rectum, and in 12% in ascending. Adenopathies were observed in 9% of the colon segments and 5% in rectum. Conclusions: A higher frequency enabled the identification of a higher number of layers. Rectal wall is thicker than the one from all the segments of the colon and there are no differences between these, namely in the ascending colon. Moreover, peri-intestinal adenopathies were rarely identified but present in asymptomatic individuals. All together, these results describe for the first time features which are relevant during staging and therapeutic management of colonic lesions.

Full Text Available Pseudo-hermaphroditism is so called when a person is born with primary sex characteristics of one sex but develops the secondary sexual characteristics that are different sex from what would actually be expected on the basis of the primary sex (testis or ovaries. Sometimes, there is partial appearance of the either of the external sex organs together that is a one between a typical penis and clitoris. In rest of the cases, the expected external sex organs are seen. Thus, pseudo-hermaphroditism can be difficult to identify until puberty. The condition may also remain hidden until adulthood. Male pseudo-hermaphroditism is an individual with XY karyotype and testes is present with a partial or complete female phenotype. This condition is attributed to hypoandrogenism in XY individuals. There is a lack in the action or presence of testosterone and dihydrotestosterone. This is a case report of a 60-year-old male who presented to the surgery out-patient services with complain of lower abdominal pain since 6 months. After proper clinical history and consent, the patient was subjected to endoscopy and contrast enhanced CT of abdomen. On endoscopy, there was restriction at passing the probe beyond the distal end of sigmoid colon and the probe could not be passed beyond it. A stricture of unknown etiology was reported. CT revealed an ill-defined elongated enhancing soft tissue lesion noted in right side of pelvis superolateral to the urinary bladder causing compression over the sigmoid colon with no obvious bowel connection. Exploratory laparotomy was them performed which revealed an elongated soft tissue lesion adherent to the sigmoid colon without obvious communication to the bowel lumen. The organ of origin could not be confirmed. The lesion was excised and sent for histopathology which revealed atretic uterine tissue.

Highlights: •Non-coding RNAs are found in the colonic crypt progenitor compartment. •Colonocytes transformed by ncNRFR are highly invasive and metastatic. •ncNRFR has a region similar to the miRNA, let-7 family. •ncNRFR expression alters let-7 activity as measured by reporter construct. •ncNRFR expression upregulates let-7b targets. -- Abstract: Recent progress has been made in the identification of protein-coding genes and miRNAs that are expressed in and alter the behavior of colonic epithelia. However, the role of long non-coding RNAs (lncRNAs) in colonic homeostasis is just beginning to be explored. By gene expression profiling of post-mitotic, differentiated tops and proliferative, progenitor-compartment bottoms of microdissected adult mouse colonic crypts, we identified several lncRNAs more highly expressed in crypt bottoms. One identified lncRNA, designated non-coding Nras functional RNA (ncNRFR), resides within the Nras locus but appears to be independent of the Nras coding transcript. Stable overexpression of ncNRFR in non-transformed, conditionally immortalized mouse colonocytes results in malignant transformation, as determined by growth in soft agar and formation of highly invasive tumors in nude mice. Moreover, ncNRFR appears to inhibit the function of the tumor suppressor let-7. These results suggest precise regulation of ncNRFR is necessary for proper cell growth in the colonic crypt, and its misregulation results in neoplastic transformation

Full Text Available Traditionally, historians begin the League of Nations’ history with the postwar settlement and the creation of the Versailles system. However, the continuity exists between the First World War and the emergence of international organization. There was no steady institution of multilateral diplomacy for the international arbitration before the War. The Hague Peace Conferences (1899, 1907 were not able to create strong international institutions. The ways out of the Great War and the mechanisms of preventing its repetition had to be looked for in the bloody conflict. The situation in the USA and in the UK differed significantly. The censorship rules that did not allow publishing essays about peace or any negotiations with the enemy were introduced. In the US they could freely discuss these issues. In the US the university academicians, businessmen, and representatives of various faiths, and prominent politicians were involved in the discussions. In the UK, the League of Nations theme was discussed by the pressure groups such as Fabian Society and selected intellectuals such as Leonard Woolf. During 1916–1917 the views of the governments and various social organizations about the League of Nations significantly differed. The public opinion and social groups demanded the creation of the international organization immediately, or as part of the post-war settlement structure. The UK government recognized the need for the creation of the League of Nations only as a part of the United States involving into the war and the strengthening of the British Empire. As a result of the League of Nations carried out signs of hybridity in a dangerous form.

Colon-available raspberry polyphenols exhibit anti-cancer effects on in vitro models of colon cancer

McDougall Gordon

2007-01-01

Full Text Available Abstract Background There is a probable association between consumption of fruit and vegetables and reduced risk of cancer, particularly cancer of the digestive tract. This anti-cancer activity has been attributed in part to anti-oxidants present in these foods. Raspberries in particular are a rich source of the anti-oxidant compounds, such as polyphenols, anthocyanins and ellagitannins. Methods A "colon-available" raspberry extract (CARE was prepared that contained phytochemicals surviving a digestion procedure that mimicked the physiochemical conditions of the upper gastrointestinal tract. The polyphenolic-rich extract was assessed for anti-cancer properties in a series of in vitro systems that model important stages of colon carcinogenesis, initiation, promotion and invasion. Results The phytochemical composition of CARE was monitored using liquid chromatography mass spectrometry. The colon-available raspberry extract was reduced in anthocyanins and ellagitannins compared to the original raspberry juice but enriched in other polyphenols and polyphenol breakdown products that were more stable to gastrointestinal digestion. Initiation – CARE caused significant protective effects against DNA damage induced by hydrogen peroxide in HT29 colon cancer cells measured using single cell microgelelectrophoresis. Promotion – CARE significantly decreased the population of HT29 cells in the G1 phase of the cell cycle, effectively reducing the number of cells entering the cell cycle. However, CARE had no effect on epithelial integrity (barrier function assessed by recording the trans-epithelial resistance (TER of CACO-2 cell monolayers. Invasion – CARE caused significant inhibition of HT115 colon cancer cell invasion using the matrigel invasion assay. Conclusion The results indicate that raspberry phytochemicals likely to reach the colon are capable of inhibiting several important stages in colon carcinogenesis in vitro.

Increased colon cancer risk after severe Salmonella infection.

Lapo Mughini-Gras

Full Text Available Colon cancer constitutes one of the most frequent malignancies. Previous studies showed that Salmonella manipulates host cell signaling pathways and that Salmonella Typhimurium infection facilitates colon cancer development in genetically predisposed mice. This epidemiological study examined whether severe Salmonella infection, usually acquired from contaminated food, is associated with increased colon cancer risk in humans.We performed a nationwide registry-based study to assess colon cancer risk after diagnosed Salmonella infection. National infectious disease surveillance records (1999-2015 for Dutch residents aged ≥20 years when diagnosed with salmonellosis (n = 14,264 were linked to the Netherlands Cancer Registry. Salmonella-infected patients were laboratory-confirmed under medical consultation after 1-2 weeks of illness. These datasets also contained information on Salmonella serovar and type of infection. Colon cancer risk (overall and per colon subsite among patients with a diagnosed Salmonella infection was compared with expected colon cancer risk in the general population. Data from the nationwide registry of histo- and cytopathology (PALGA and Statistics Netherlands (CBS allowed assessing potential effects of age, gender, latency, socioeconomic status, genetic predisposition, inflammatory bowel disease (IBD, and tumor features. We found that compared to the general population, colon cancer risk was significantly increased (standardized incidence ratio [SIR] 1.54; 95%CI 1.09-2.10 among patients with Salmonella infection diagnosed <60 years of age. Such increased risk concerned specifically the ascending/transverse colon (SIR 2.12; 95%CI 1.38-3.09 after S. Enteritidis infection (SIR 2.97; 95%CI 1.73-4.76. Salmonellosis occurred more frequently among colon cancer patients with pre-infectious IBD, a known risk factor for colon cancer. Colon tumors of patients with a history of Salmonella infection were mostly of low grade
