Balamuthia mandrillaris transmitted through organ transplantation --- Mississippi, 2009. (6/24)

On December 14, 2009, a physician in Mississippi contacted CDC to report possible transplant-transmitted encephalitis in two kidney transplant recipients who shared the same organ donor. Histopathologic testing of donor autopsy brain tissue at CDC showed amebae, and subsequent testing of specimens from the donor and the two kidney recipients confirmed transmission by transplantation of Balamuthia granulomatous amebic encephalitis (GAE), a rare disease caused by Balamuthia mandrillaris, a free-living ameba found in soil. One kidney recipient, a woman aged 31 years, died; the other recipient, a man aged 27 years, survived with neurologic sequelae. Recipients of the heart and liver from the same donor received preemptive therapy and have shown no signs of infection. The donor, a previously healthy boy aged 4 years, was presumed to have died from acute disseminated encephalomyelitis (ADEM), an autoimmune neurologic disease, after infection with influenza A. An investigation was conducted by the state health departments in Mississippi, Kentucky, Florida, and Alabama and CDC to characterize the cases, elucidate possible exposures in the donor, and develop recommendations for early detection and prevention. This is the first reported transmission of Balamuthia by organ transplantation. Clinicians should be aware of Balamuthia infection as a potentially fatal cause of encephalitis. Organ procurement organizations (OPOs) and transplant centers should be aware of the potential for Balamuthia infection in donors with encephalitis of uncertain etiology, and OPOs should communicate this elevated risk for infection to transplant centers so they can make an informed risk assessment in the decision to accept an organ.  (+info)

Notes from the field: transplant-transmitted Balamuthia mandrillaris --- Arizona, 2010. (7/24)

On August 23, 2010, CDC was notified regarding two organ transplant recipients in Arizona who had encephalitis with multiple ring-enhancing lesions revealed by cerebral magnetic resonance imaging. The common organ donor, a Hispanic male landscaper aged 27 years, had died in Arizona from a presumed stroke on July 21. He had a large skin lesion for approximately 6 months on his back that he had attributed to an insect bite. The ill recipients, a male liver recipient aged 56 years, and a male recipient of a kidney and pancreas aged 24 years, received organ transplants on July 22. In addition, two other recipients received organs from this donor: an adult male heart recipient received his transplant in California on July 22, and an adult male kidney recipient received his transplant in Utah on July 23.  (+info)

Free-living amoebae (or "FLA") in the Amoebozoa group are important causes of disease in humans and animals. Naegleria fowleri is sometimes included in the group "free-living amoebae", and it causes a condition traditionally called primary amoebic meningoencephalitis. However, Naegleria is now considered part of the Excavata, not the Amoebozoa, and is considered to be much more closely related to Leishmania and Trypanosoma. Acanthamoeba spp. and Balamuthia mandrillaris are opportunistic free-living amoebae capable of causing granulomatous amoebic encephalitis (GAE) in individuals with compromised immune systems. Acanthamoeba spp. have been found in soil; fresh, brackish, and sea water; sewage; swimming pools; contact lens equipment; medicinal pools; dental treatment units; dialysis machines; heating, ventilating, and air conditioning systems; mammalian cell cultures; vegetables; human nostrils and throats; and human and animal brain, skin, and lung tissues.

The ultra-structure of the shell and the morphometric variability of soil inhabiting testate amoeba Lamtopyxis callistoma from Madagascar were studied by using light- and scanning electron microscopy. The biometrical characteristic of the species was made on the basis of 75 specimens measured. In addition to the diameter of the shell, six other shell characters were described biometrically for the first time. The analysis of the variation coefficients shows that the studied population of L. callistoma is comparatively homogeneous and almost all measured characters are weakly to moderate variable (CV less than 10%). Scanning electron microscopy (SEM) studies on the shell ultra-morphology show that it has a smooth apertural surface with a thick layer of porous and fibrous organic cement and a rough dorsal surface composed of bigger and angular pieces of quartz. The shell wall has a thickness of about 5-6 µm and is composed of three layers. Unlike the previously accepted opinion that species is

The unikonts have a triple-gene fusion that is lacking in the bikonts. The three genes that are fused together in the unikonts, but not bacteria or bikonts, encode enzymes for synthesis of the pyrimidine nucleotides: carbamoyl phosphate synthase, dihydroorotase, aspartate carbamoyltransferase. This must have involved a double fusion, a rare pair of events, supporting the shared ancestry of Opisthokonta and Amoebozoa.. Cavalier-Smith[1] originally proposed that unikonts ancestrally had a single flagellum and single basal body. This is unlikely, however, as flagellated opisthokonts, as well as some flagellated Amoebozoa, including Breviata, actually have two basal bodies, as in typical bikonts (even though only one is flagellated in most unikonts). This paired arrangement can also be seen in the organization of centrioles in typical animal cells.

Horizontal transfer (HT) of transposable elements (TEs) plays a key role in prokaryotic evolution, and mounting evidence suggests that it has also had an important impact on eukaryotic evolution. Although many prokaryote-to-prokaryote and eukaryote-to-eukaryote HTs of TEs have been characterized, only few cases have been reported between prokaryotes and eukaryotes. Here, we carried out a comprehensive search for all major groups of prokaryotic insertion sequences (ISs) in 430 eukaryote genomes. We uncovered a total of 80 sequences, all deriving from the IS607 family, integrated in the genomes of 14 eukaryote species belonging to four distinct phyla (Amoebozoa, Ascomycetes, Basidiomycetes, and Stramenopiles). Given that eukaryote IS607-like sequences are most closely related to cyanobacterial IS607 and that their phylogeny is incongruent with that of their hosts, we conclude that the presence of IS607-like sequences in eukaryotic genomes is the result of several HT events.

Recent molecular and cellular evidence indicates that eukaryotes comprise three major lineages: the probably ancestrally uniciliate protozoan phylum Amoebozoa; the ancestrally posteriorly uniciliate opisthokont clade (animals, Choanozoa, and fungi); and a very diverse ancestrally biciliate clade, the bikonts-plants, chromalveolates, and excavate and rhizarian Protozoa. As Heliozoa are the only eukaryote phylum not yet placed on molecular sequence trees, we have sequenced the 18S rRNA genes of three centrohelid heliozoa, Raphidiophrys ambigua, Heterophrys marina, and Chlamydaster sterni, to investigate their phylogenetic position. Phylogenetic analysis by distance and maximum likelihood methods allowing for intersite rate variation and invariable sites confirms that centrohelid heliozoa are a robust clade that does not fall within any other phyla. In particular, they are decisively very distant from the heterokont pedinellid chromists, at one time thought to be related to heliozoa, and lack the ...

For the over-all classification I have followed the six-kingdom system by Thomas Cavalier-Smith, who has played a major part in developing our current understanding of large-scale relationships, and in my opinion does the best job presenting them in a framework that is useful for discussing the groups in question. An overview giving classes for most algae and protozoans appears in "Unravelling the Algae" (2007) eds. Brodie and Lewis. However, the kingdoms Chromista and Protozoa were also substantially changed in Cavalier-Smith (2010), removing one of the main differences remaining from the phylogeny determined by other authors. For ciliates I have mainly taken the classes and orders from "The Ciliated Protozoa" 3rd ed. (2008) by Lynn, except for the litostomes which follow Vďačný et al. (2011). For the Amoebozoa I have followed the updated classification from Smirnov et al. (2011). For animals many groups are been more or less stable, given in detail in for instance "Synopsis and ...

Jane observed the chimpanzees through binoculars from a peak in the forest. Gradually the chimpanzees became accostumed to her presence. Jane uncovered many aspects of chimpanzee behaviour during her first years at Gombe National Park. In October 1960, she observed a chimpanzee using and making tools to fish for termites. The discovery challenged the definition current at that time: Man the Toolmaker. Because of her research, we now know that chimpanzees hunt for meat and use tools. The longer the research continued, the more it became obvious how like us chimpanzees really are.. Gombe Stream Research Centre. What some people believed would last only a few months has now become the longest field study of any animal species in their natural surroundings. Research at Gombe continues to this day, mostly by a trained tream of Tanzanians. Moral support from the Tanzanian government is a large reason for the longevity of the research at Gombe Stream Reserach Centre.. Jane Goodall received her Ph.D. ...
The IEDB track in Figure 2 shows that the protein encoded by the nucleotide sequence in this view is partially targeted by four previously published antibodies: an unnamed one from a screen (TGEESA), 12B5-1-1, 14G7 and 4G7. Detailed information about each of these antibodies can be viewed by clicking on the antibody name in the display. In this instance, the details reveal that 14G7 and 4G7 were first described by Olal et al. (2012)17 and Qiu et al. (2011)18, respectively. Comparing the IEDB and PDB tracks, note that the 14G7 IEDB feature maps to the same region as the 2y6s feature in the PDB track: a crystal structure of the antibody 14G7 is available in the Protein Data Bank under accession 2y6s. A click on the 2y6s feature in the display will show this structure and a link to the primary citation. Olal et al. note that the most significant residues for 14G7 antibody binding are TIAG. Note that there is no matching PDB track feature for the 4G7 antibody: a crystal structure for that antibody, ...

Cleve Hicks deed een vijfjarig veldonderzoek naar het voorkomen van chimpansees in het noorden van de Democratische Republiek Kongo (het Bili-Uelegebied). Hoewel er twijfels bestonden over het überhaupt voorkomen van chimpansees in dit gebied, heeft het onderzoek aan het licht gebracht dat noord-Kongo bewoond wordt door de oostelijke ondersoort van de chimpansee (Pan troglodytes schweinfurthii); de totale populatie wordt geschat tussen de 35.000 en 65.000 individuen. Dat deze grote populatie tot voor kort ontsnapt was aan de aandacht van wetenschappers en natuurbeschermers heeft vooral te maken met de ontoegankelijkheid van het gebied en de politieke onrust in Kongo. De totale populatie lijkt vrij uniform over het gebied verdeeld te zijn en wordt verder gekenmerkt door een uniforme cultuur: in een gebied ter grootte van zon 35.000 vierkante kilometer delen de chimpansees een set van gedragskenmerken zoals het maken van grondnesten en bladkussens, met gereedschap vissen naar mieren en het ...

O Sar, ou supergrupo SAR, é unha proposta de grupo monofilético de protistas que acolle aos stramenopiles (tamén chamados heterokontos), aos apicomplexos (mizozoos e alveolados) e aos rizarios [1][2][3][4]. O acrónimo "SAR" está formado pola inicial de cada un destes tres grupos (stramenopiles + Alveolata + Rhizaria). O termo "Harosa" (co nivel de subreino) tamén foi utilizado para referirse ao supergrupo SAR.[5]. SAR inclúe a máis especies protistas ca todos os demais grupos de eucariotas. Os SAR son diversos na súa citoloxía, organización morfolóxica e ciclos vitais [6][7].. As características morfolóxicas e os primeiros estudos filoxenéticos fixeron que se considerara que os protistas constaban de seis grupos monofiléticos, ou supergrupos: Opisthokonta, Amoebozoa, Excavata, Archaeplastida, Chromalveolata e Rhizaria. Porén, non se coñecía con claridade a relación entre eses grupos. Os estudos filoxenéticos recentes revelaron que os cromalveolados son un grupo ...

We present a collection of small multiple graphics that support analysis and understanding of the geography of labour-market self-containment across Londons 33 boroughs. Ratios describing supply-side self-containment, the extent to which working residents access jobs locally, and demand-side self containment, the extent to which local jobs are filled by local resident workers, are first calculated for professional and non-professional occupations and encoded directly through geographically-arranged bar charts. The full distribution of workers into-and out-of- boroughs that underpins these ratios is then revealed via Origin-Destination flows maps (OD maps) - sets of geographically-arranged choropleths. In order to make relative and absolute comparison of borough-to-borough frequencies between occupation types, these OD maps are coloured according to signed chi-square residuals: for every borough-to-borough pair, we compare the observed number of flows to access professional versus ...
Downloadable! Accessibility measures the potential of opportunities for interaction. This paper proposes and explores a new flow-based measure, place rank using origin-destination information. Both impedance and value of opportunities are embedded in the dataset that includes the origin and destination of each person within the studied region. Individuals contribute to the place rank at their destination (work) zone with a power that depends on the attractiveness of the zone of origin. In this paper we demonstrate this place rank measure for three activities (Jobs, Resident Workers, and Health Services) in the Minneapolis-St. Paul metropolitan region and Jobs in Montreal, Canada. We compare place rank to traditional measures of accessibility. Since place rank is based on actual choices of origins and destinations it is a measure of realized rather than potential opportunities, and so unlike accessibility measures. Also it does not require the knowledge of travel time between all origins and

Dictyostelid social amoebae are a large and ancient group of soil microbes with an unusual multicellular stage in their life cycle. Taxonomically, they belong to the eukaryotic supergroup Amoebozoa, the sister group to Opisthokonta (animals + fungi). Roughly half of the similar to 150 known dictyostelid species were discovered during the last five years and probably many more remain to be found. The traditional classification system of Dictyostelia was completely overturned by cladistic analyses and molecular phylogenies of the past six years. As a result, it now appears that, instead of three major divisions there are eight, none of which correspond to traditional higher-level taxa. In addition to the widely studied Dictyostelium discoideum, there are now efforts to develop model organisms and complete genome sequences for each major group. Thus Dictyostelia is becoming an excellent model for both practical, medically related research and for studying basic principles in cell-cell communication ...

The potential of human activities, including research, to alter parasite transmission ecology in wildlife is unknown. We examined gastrointestinal parasitism in chimpanzees (Pan troglodytes schweinfurthii) in Budongo Forest, Uganda. Trail use and time spent on the ground was recorded during 10 months of observations in four sites with differing human disturbance. Disturbance was quantified using transect plots (n = 320). Fecal (n = 435) samples were examined for helminth eggs, larvae, and for protozoan cysts. Individuals that spent more time on the ground had more infections and higher intensity infections. Prevalence of 13 parasite species was similar across sites, but percentage of multiple infections and infection intensity differed, as did ground use. Chimpanzees at the long-term research site spent more time on the ground or on human trails. We hypothesize that researcher presence and trail creation may influence ground use, and thereby parasite burden, by altering trade-offs between foraging and
The discovery that viruses related to HIV were found naturally in healthy African primates was first made in the mid-1980s, and in 1989 came the first publication (by Martine Peeters group) demonstrating that SIVs that were related to HIV-1 were found in common chimpanzees, Pan troglodytes. (The actual genetic sequences were published by Simon Wain-Honbsons group in 1990.) Given this sound start, it is rather surprising that so little progress was made in SIV research in central Africa during the next nine years. Early in 1999, the Hahn/Sharp group claimed that they had found the most closely related SIV to HIV-1 in Pan troglodytes troglodytes (Ptt), a chimpanzee subspecies found in Congo Brazzaville, Gabon, Cameroon and Equatorial Guinea, and drew a distinction between these SIVs, and others SIVs found in Pan troglodytes schweinfurthii (Pts), the chimp subspecies that is located further east, in the DRC, Uganda and Tanzania. Superficially, this seemed reasonable, in that those Ptt SIVs that ...
SIVcpz infection is common and widespread in two chimpanzee subspecies, the central chimpanzee (P. t. troglodytes) in west central Africa and the eastern chimpanzee (P. t. schweinfurthii) in the Democratic Republic of the Congo (DRC) and countries to the east [1-5]. Two other subspecies in west Africa (P. t. verus) and Nigeria/Cameroon (P. t. ellioti) are free of SIVcpz infection [3, 6, 7], because chimpanzees acquired this virus relatively more recently following the cross-species transmission and recombination of SIVs infecting monkeys on which they prey [8]. SIVcpz has been reported to have a negative impact on the health, reproduction and lifespan of chimpanzees living in the wild. Comprehensive natural history studies in Gombe National Park, Tanzania, revealed that SIVcpz-infected chimpanzees have a 10-16 fold increased risk of death and can develop CD4+ T cell depletion and AIDS-like immunopathology [9, 10]. Moreover, SIVcpz infected females were found to have lower birth rates and higher ...

Chloramines have been used safely in the United States and Canada for many years. For most normal uses of potable water, chloraminated water is the same as chlorinated water. There are two groups of people, however, who need to take special care with chloraminated water: kidney dialysis patients and fish owners.. Chloramines must be removed from the water used in the kidney dialysis process and from water that is used in fish tanks and ponds.. Kidney Dialysis. Kidney dialysis patients can safely drink, cook, and bathe in chloraminated water. However, chloramines must be removed from the water used in kidney dialysis machines. Dialysis systems will require some modifications to remove the chloramines. Check with your physician to be certain the necessary changes are made. All medical facilities that perform kidney dialysis have been notified of this change to chloraminated water treatment. According to the ESRD [End Stage Renal Disease] federal regulations, these facilities are responsible for ...
The traditional view of RNA being merely an intermediate in the transfer of genetic information, as mRNA, spliceosomal RNA, tRNA, and rRNA, has become outdated. The recent discovery of numerous regulatory RNAs with a plethora of functions in biological processes has truly revolutionized our understanding of gene regulation. Tiny RNAs such as microRNAs and small interfering RNAs play vital roles at different levels of gene control. Small nucleolar RNAs are much more abundant than previously recognized, and new functions beyond processing and modification of rRNA have recently emerged. Longer non-coding RNAs (ncRNAs) can also have important regulatory roles in the cell, e.g., antisense RNAs that control their target mRNAs. The majority of these important findings arose from analyses in various model organisms. In this review, we focus on ncRNAs in the social amoeba Dictyostelium discoideum. This important genetically tractable model organism has recently received renewed attention in terms of ...
Vaults and their major component MVP have been implicated in a variety of cellular processes including drug resistance, subcellular transport and cell differentiation (Mossink et al., 2003; Suprenant, 2002) as well as regulation of intracellular signaling cascades including the PI 3-kinase (Yu et al., 2002) and the MAP kinase pathway (Kolli et al., 2004). Here, we identify MVP as an IFN-γ-upregulated gene and present profound evidence that MVP interferes with IFN-γ-mediated STAT signal transduction. Herewith, the IFN-γ-induced JAK/STAT pathway is the third intracellular phosphorylation cascade demonstrated to be regulated by MVP/vaults. These observations suggest that the complex vault ribonucleoprotein particle represents a versatile platform for the intracellular regulation of multiple signal pathways transmitted from the cell surface to the nucleus.. In a previous study, we have identified Sp-family members as important transcription factors activating the MVP promoter by binding to a ...

The most recent crop…
Just as water molecules spontaneously arrange to form geometric snowflakes, the â socialâ amoeba Dictyostelium discoideum transitions from a collection of unicellular organisms to a fruiting body during its life cycle. This aggregation is guided by cyclic AMP (cAMP): when stimulated with cAMP, cells respond by producing and secreting more of the molecule, which, once levels reach a threshold, results in nondissipating waves of cAMP and collective amoeba movement..

Autophagy is a eukaryotic catabolic pathway that degrades and recycles cellular components to maintain homeostasis. It can target protein aggregates, superfluous biomolecular complexes, dysfunctional and damaged organelles, as well as pathogenic intracellular microbes. Autophagy is a dynamic process in which the different stages from initiation to final degradation of cargo are finely regulated. Therefore, the study of this process requires the use of a palette of techniques, which are continuously evolving and whose interpretation is not trivial. Here, we present the social amoeba Dictyostelium discoideum as a relevant model to study autophagy. Several methods have been developed based on the tracking and observation of autophagosomes by microscopy, analysis of changes in expression of autophagy genes and proteins, and examination of the autophagic flux with various techniques. In this review, we discuss the pros and cons of the currently available techniques to assess autophagy in this organism.
The Rhizaria are a heterogeneous assemblage encompassing lineages such as Foraminifera, radiolarians and euglyphid testate amoebae, chlorarachniophytes, parasitic groups (Phytomyxea, Haplosporidia), as well as a multitude of other lesser-known flagellates (figure 2b) that emerge as having fundamental ecological roles [13,74-76]. Filamentous pseudopodia are a recurrent morphological feature among amoeboid members of Rhizaria, in contrast to the lobose or broad pseudopodia of many Amoebozoa. Complete sexual life cycles are documented for two lineages (Foraminifera and Gromia); karyogamy or meiosis (direct evidence) has been observed in five lineages (Euglyphida, Thecofilosea, Chlorarachniophyta, Plasmodiophorida and Phaeodarea); and indirect evidence (such as cell fusion or formation of putative gametes) has been witnessed in five lineages (Acantharea, Polycystinea, Cercomonas, Helkesimastix and Lateromyxa).. There are at least two lineages in the Rhizaria with confirmed sexual life cycles. ...
BackgroundThe Nuclear Pore Complex (NPC) facilitates molecular trafficking between nucleus and cytoplasm and is an integral feature of the eukaryote cell. It exhibits eight-fold rotational symmetry and is comprised of approximately 30 nucleoporins (Nups) in different stoichiometries. Nups are broadly conserved between yeast, vertebrates and plants, but few have been identified among other major eukaryotic groups.. Methodology/Principal FindingsWe screened for Nups across 60 eukaryote genomes and report that 19 Nups (spanning all major protein subcomplexes) are found in all eukaryote supergroups represented in our study (Opisthokonts, Amoebozoa, Viridiplantae, Chromalveolates and Excavates). Based on parsimony, between 23 and 26 of 31 Nups can be placed in LECA. Notably, they include central components of the anchoring system (Ndc1 and Gp210) indicating that the anchoring system did not evolve by convergence, as has previously been suggested. These results significantly extend earlier results ...
Background: Many microbial phenotypes are the product of cooperative interactions among cells, but their putative fitness benefits are often not well understood. In the cellular slime mold Dictyostelium discoideum, unicellular amoebae aggregate when starved and form multicellular fruiting bodies in which stress-resistant spores are held aloft by dead stalk cells. Fruiting bodies are thought to be adaptations for dispersing spores to new feeding sites, but this has not been directly tested. Here we experimentally test whether fruiting bodies increase the rate at which spores are acquired by passing invertebrates.. Results: Drosophila melanogaster accumulate spores on their surfaces more quickly when exposed to intact fruiting bodies than when exposed to fruiting bodies physically disrupted to dislodge spore masses from stalks. Flies also ingest and excrete spores that still express a red fluorescent protein marker.. Conclusions: Multicellular fruiting bodies created by D. discoideum increase the ...
Intestinal protozoa are spread by the fecal-oral route, so infections are widespread in areas with inadequate sanitation and water treatment. They are also common in the US in settings where fecal incontinence and poor hygiene prevail, as occur in mental institutions and day care centers. Occasionally, large waterborne outbreaks of intestinal protozoan infection have occurred in the US (eg, the massive waterborne Cryptosporidium outbreak in Milwaukee in 1993). Some GI protozoa are spread sexually, especially with practices involving oral-anal contact, and several protozoan species cause severe opportunistic infections in patients with AIDS ...
In Qatar, the ruling Al Thani (الثاني) family continued to hold power following the declaration of independence in 1971. The head of state is the Emir, and the right to rule Qatar is passed on within the Al Thani family. Politically, Qatar is evolving from a traditional society into a modern welfare state. Government departments have been established to meet the requirements of social and economic progress. The Basic Law of Qatar 1970 institutionalized local customs rooted in Qatars conservative Islamic heritage, granting the Emir preeminent power. The Emirs role is influenced by continuing traditions of consultation, rule by consensus, and the citizens right to appeal personally to the Emir. The Emir, while directly accountable to no one, cannot violate the Sharia (Islamic law) and, in practice, must consider the opinions of leading notables and the religious establishment. Their position was institutionalized in the Advisory Council, an appointed body that assists the Emir in ...

The social amoeba Dictyostelium discoideum is a well-established model organism to study the interaction between bacteria and phagocytes. In contrast, research using D. discoideum as a host model for fungi is rare. We describe a comprehensive study, which uses D. discoideum as a host model system to investigate the interaction with apathogenic (Saccharomyces cerevisiae) and pathogenic (Candida sp.) yeast. We show that Dictyostelium can be co-cultivated with yeasts on solid media, offering a convenient test to study the interaction between fungi and phagocytes. We demonstrate that a number of D. discoideum mutants increase (atg1-, kil1-, kil2-) or decrease (atg6-) the ability of the amoebae to predate yeast cells. On the yeast side, growth characteristics, reduced phagocytosis rate, as well as known virulence factors of C. albicans (EFG1, CPH1, HGC1, ICL1) contribute to the resistance of yeast cells against predation by the amoebae. Investigating haploid C. albicans strains, we suggest using the amoebae
The social amoeba Dictyostelium discoideum senses the bacterial metabolite folic acid to track down bacteria. Previous studies suggested that the folic acid receptor is a serpentine receptor. In this study, I examined the transcriptional level changes of 46 putative serpentine receptor genes after folic acid stimulation. Seven candidate genes showed significantly up-regulated transcriptional levels, including fslA, fslB, fslH, fslJ, fslK, grlB, and grlD. Unfortunately, subsequent disruption of these genes did not affect folic acid sensing. Among these putative serpentine receptor gene mutants, grlB- cells exhibited delayed aggregation. Further studies suggest that GrlB is required for GABA binding. Detailed characterization of GABA metabolism indicates that GABA is used as an ancient signal during early development and culmination. Loss of GABA leads to a delay in early development and reduced detergent-resistant spores. GABA metabolism and signaling are regulated by distinct genes in different ...
Downloadable! This study applies the skill-cell approach introduced by Borjas (2003) in order to identify the causal impact of immigration on the employment opportunities of resident workers, using data from two different samples, namely two waves of the Census of Population (1991 and 2001) and the Greek Labour Force Survey (1998-2015). Grouping workers in three education and eight experience classes at the national level, we find small adverse effects on the employment outcomes of natives, that are generally not sensitive to alternative education and experience classifications and when accounting for the effective experience of immigrants. However, as for the period between 1998 and 2015, our findings appear to be driven by the negative influence of immigration ascertained in the sub-period during the Great Recession. Remarkably, there is some evidence of complementarity when the pre-recession period (1998- 2007) is considered. The less-skilled natives, appear to be the group of workers which is more
The day Joshua Frase was born, his parents Alison and Paul, were given grave news about their newborns life - he most likely would not survive that day. His weakened muscles could not function normally which affected his ability to breathe on his own. Miraculously, Joshua survived, and when he was three-months old, a muscle biopsy revealed he had Myotubular Myopathy (MTM), a congenital muscular disorder so rare only 50 known cases existed in 1995 when he was diagnosed. MTM is caused by mutations in the myotubularin gene (MTM1) and affects the strength of skeletal muscles leading to breathing and swallowing difficulties. Approximately 50 percent of those diagnosed with MTM do not survive beyond age two. With limited information, two facts were certain; it was life-threatening and there was no cure.. As Alison and Paul struggled to keep their son alive, they felt helpless and alone. They found themselves resuscitating their son countless times, but Joshua had a strong will to live. His passion ...

The adoption of a three-year budget framework to help shield government spending from revenue volatility and enable better use of resources is welcomed.
The haploid social amoeba Dictyostelium discoideum is a well-defined model organism which is amenable to diverse biochemical, cell biological, and molecular genetic approaches. The similarities between the Dictyostelium and mammalian cells extend to membrane trafficking, endocytic transit and sorting events. Therefore, Dictyostelium opens the exciting possibility of investigating and manipulating both sides of the Legionella-host interaction. The intrinsic features of Dictyostelium and a set of well-established molecular tools enabled the authors to prove that Dictyostelium is a representative cellular model for Legionella infection. The research areas presented in this chapter include the analysis of the transcriptional host cell response to Legionella infection and the use of custom tailored Dictyostelium mutant cells to identify determinants of susceptibility and resistance. In order to describe the transcriptional host cell response to Legionella infection, the authors employed DNA-microarrays which
The absolute centrality of the resurrection of Christ to Christian faith can be seen clearly articulated by major preachers-theologians from the Apostle Paul through Augustine, Luther, Barth, and Thielicke, to take a historical sampling. These men agreed on interpreting the resurrection as bodily (a changed body, but a body nonetheless) and in uniting Christs resurrection with that of Christians. Though tone and emphases differed considerably, they all took seriously and combated the forms of doubt that these affirmations took in their own day, and played out the consequences of resurrection faith for life in this world. The intellectual seriousness with which they engaged the questions of their own time, as well as the intensity with which they related theological affirmation of the resurrection to the perennial threats of sin, death, and final futility, provide a challenge to do likewise to todays theologians and preachers.
Balamuthia mandrillaris is a free-living amoeba that causes Balamuthia amoebic encephalitis, a fatal disease in humans and animals. Its ecology and risk to humans is largely unknown, although Balamuthia infections have been mostly associated with soil-related activities. Ecology studies are hampered by difficulty in isolating the amoeba by culture methods used for other free-living amoebae. In this study, a DNA extraction method and nested PCR was developed for rapid detection of B. mandrillaris from environmental samples, without needing primary culturing. More than 25% of soil samples were positive for B. mandrillaris, predominantly those from high temperature countries. Additionally, B. mandrillaris was frequently found in thermally polluted water, with almost 50% of samples positive. To facilitate the isolation of B. mandrillaris from environmental samples, immunomagnetic separation with B. mandrillaris antibodies was investigated. For this, poly- and monoclonal antibodies were produced and ...
Case histories are presented of 2 individuals (a 5-year-old girl and 64-year-old man) who developed encephalitis caused by the free-living amoeba Balamuthia mandrillaris Both individuals survived after diagnosis and initiation of effective antimicrobial therapy. Immunostaining for Balamuthia-specific antibody levels identified the causative agent of the infections. Antimicrobial therapy with flucytosine, pentamidine, fluconazole, sulfadiazine, and a macrolide antibiotic (azithromycin or clarithromycin) was initiated. Phenothiazines (thioridazine and trifluoperazine) were also used. Both patients recovered, and there was no evidence of recrudescence of the disease at 2 and 6 years after onset of symptoms. Awareness of Balamuthia as the causative agent of encephalitis and early initiation of antimicrobial therapy were critical to the recovery of both patients. Although optimal antimicrobial therapy for Balamuthia amoebic encephalitis has yet to be determined, the antimicrobials used in these 2 ...

Traditionally, there are three groups comprising Eumycetozoa: myxogastrids, dictyostelids, and the so-called protostelids. Dictyostelids and myxogastrids both make multicellular fruiting bodies that may contain hundreds of spores. Protostelids are those amoebae that make simple fruiting bodies consisting of a stalk and one or a few spores. Protostelid-like organisms have been suggested as the progenitors of the myxogastrids and dictyostelids, and they have been used to formulate hypotheses on the evolution of fruiting within the group. Molecular phylogenies have been published for both myxogastrids and dictyostelids, but little molecular phylogenetic work has been done on the protostelids. Here we provide phylogenetic trees based on the small subunit ribosomal RNA gene (SSU) that include 21 protostelids along with publicly

On the morphology, biometry and biogeography of Lamtopyxis callistoma (Amoebozoa: Arcellinida)On the morphology, biometry and biogeography of Lamtopyxis callistoma (Amoebozoa: Arcellinida)

The ultra-structure of the shell and the morphometric variability of soil inhabiting testate amoeba Lamtopyxis callistoma from Madagascar were studied by using light- and scanning electron microscopy. The biometrical characteristic of the species was made on the basis of 75 specimens measured. In addition to the diameter of the shell, six other shell characters were described biometrically for the first time. The analysis of the variation coefficients shows that the studied population of L. callistoma is comparatively homogeneous and almost all measured characters are weakly to moderate variable (CV less than 10%). Scanning electron microscopy (SEM) studies on the shell ultra-morphology show that it has a smooth apertural surface with a thick layer of porous and fibrous organic cement and a rough dorsal surface composed of bigger and angular pieces of quartz. The shell wall has a thickness of about 5-6 µm and is composed of three layers. Unlike the previously accepted opinion that species is

  • The Amoebozoa also include the mycetozoan slime moulds , multinucleate or multicellular forms which produce spores and are usually visible to the unaided eye. (wikipedia.org)
  • It appears (based on molecular genetics) that the members of Amoebozoa form a sister group to animals and fungi, diverging from this lineage after it had split from the other groups, as illustrated below in a simplified diagram: Strong similarities between Amoebozoa and Opisthokonts lead to the hypothesis that they form a distinct clade.
