Most are malignant except the insulin-producing tumors (INSULINOMA).North Carolina
In vivo expression of the nucleolar group I intron-encoded I-dirI homing endonuclease involves the removal of a spliceosomal intron. (1/489)The Didymium iridis DiSSU1 intron is located in the nuclear SSU rDNA and has an unusual twin-ribozyme organization. One of the ribozymes (DiGIR2) catalyses intron excision and exon ligation. The other ribozyme (DiGIR1), which along with the endonuclease-encoding I-DirI open reading frame (ORF) is inserted in DiGIR2, carries out hydrolysis at internal processing sites (IPS1 and IPS2) located at its 3' end. Examination of the in vivo expression of DiSSU1 shows that after excision, DiSSU1 is matured further into the I-DirI mRNA by internal DiGIR1-catalysed cleavage upstream of the ORF 5' end, as well as truncation and polyadenylation downstream of the ORF 3' end. A spliceosomal intron, the first to be reported within a group I intron and the rDNA, is removed before the I-DirI mRNA associates with the polysomes. Taken together, our results imply that DiSSU1 uses a unique combination of intron-supplied ribozyme activity and adaptation to the general RNA polymerase II pathway of mRNA expression to allow a protein to be produced from the RNA polymerase I-transcribed rDNA.

Polymerization of Acanthamoeba actin. Kinetics, thermodynamics, and co-polymerization with muscle actin. (2/489)The kinetics and thermodynamics for the polymerization of purified Acanthamoeba actin were studied and compared to muscle actin. Polymerization was qualitatively similar for the two actins with a rate-limiting nucleation step followed by rapid polymer extension. Polymerization occurred only above a threshold critical concentration which varied with polymerization conditions for each actin. In the presence of 2 mM MgCl2, nucleation of both actins was rapid and their critical concentrations were similarly low and not detectably dependent on temperature. In 0.1 M KCl, the rates of nucleation of both actins were much slower than when Mg2+ was present and were significantly different from each other. Also, under these conditions, the critical concentrations of Acanthamoeba and muscle actin were significantly different and both varied markedly with temperature. These quantitative differences between the two actins could be attributed to differences in both their enthalpies and entropies of polymerization, Acanthamoeba actin having the more positive deltaH and delta S. Co-polymerization of the two actins was also demonstrated. Overall, however, there were no qualitative differences between Acanthamoeba and muscle actin that would suggest a unique role for the monomer-polymer equilibrium of cytoplasmic actin in cell motility.

Timing of nucleolar DNA replication in Amoeba proteus. (3/489)Light- and electron-microscope autoradiography have been used to follow the incorporation of [3H]thymidine at different stages during the interphase of synchronously growing populations of Amoeba proteus. Two main patterns were found for tritiated thymidine incorporation, i.e. DNA synthesis. The major incorporation was in the central region of the nucleus, but a lesser degree of incorporation occurred in the nucleolar region. The bulk of this nucleolar DNA was found to be late replicating, i.e. it replicated during the G2 phase. (+info)
Serum antibodies to Balamuthia mandrillaris, a free-living amoeba recently demonstrated to cause granulomatous amoebic encephalitis. (4/489)Free-living amoebae cause three well-defined disease entities: a rapidly fatal primary meningoencephalitis, a chronic granulomatous amoebic encephalitis (GAE), and a chronic amoebic keratitis. GAE occurs in immunocompromised persons. Recently, another type of free-living amoeba, Balamuthia mandrillaris, has been shown to cause GAE. The finding that this amoeba has caused infection in some healthy children has raised the possibility that humans may lack immunity to B. mandrillaris. Human serum was examined for the presence of surface antibodies specific for this amoeba by immunofluorescence. Sera from adults contained titers of 1/64-1/256 of anti-B. mandrillaris antibodies (IgM and IgG classes), which did not cross-react with other amoebae. Cord blood contained very low antibody levels, but levels similar to those in adults were seen in serum of 1- to 5-year-old children. (+info)
The role of actin in the temperature-dependent gelation and contraction of extracts of Acanthamoeba. (5/489)The temperature-dependent assembly and the interaction of Acanthamoeba contractile proteins have been studied in a crude extract. A cold extract of soluble proteins from Acanthamoeba castellanii is prepared by homogenizing the cells in a sucrose-ATP-ethyleneglycol-bis-(beta-aminoethyl ether) N,N'-tetraacetic acid buffer and centrifuging at 136,000 g for 1 h. When this supernate of soluble proteins is warmed to room temperature, it forms a solid gel. Upon standing at room temperature, the gel slowly contracts and squeezes out soluble components. The rates of gelation and contraction are both highly temperature dependent, with activation energies of about 20 kcal per mol. Gel formation is dependent upon the presence of ATP and Mg++. Low concentrations of Ca++ accelerate the contractile phase of this phenomenon. The major protein component of the gel is actin. It is associated with myosin, cofactor, a high molecular weight protein tentatively identfied as actin-binding protein, and several other unidentified proteins. Actin has been purified from these gels and was found to be capable of forming a solid gel when polymerized in the presence of ATP, MgCl3, and KCL. The rate of purified actin polymerication is very temperature dependent and is accelerated by the addition of fragments of muscle actin filaments. These data suggest that Acanthamoeba contractile proteins have a dual role in the cell; they may generate the forces for cellular movements and also act as cytoskeletal elements by controlling the consistency of the cytoplasm.

Isolation and electrophoretic analysis of nucleoli, phenol-soluble nuclear proteins, and outer cyst walls from Acanthamoeba castellanii during encystation initiation. (6/489)A technique is described for isolating nuceoli from Acanthamoeba castellanii. Nuclei isolated by a modification of the technique of F. J. Chlapowski and R. N. Band (1971) are sonicated in a surcrose-Tris-MgSO4-KC1-Triton X-100 buffer and centrifuged on a linear sucrose gradient extending from 1.3 M to 1.5 M with a 2.6 M cushion, at 41000 rpm for 90 min. The only apparent contaminants in the nucleolar preparation are outer cyst walls. A procedure is described for the isolation of chemically pure outer cyst walls, and a comparison of the proteins with the nucleolar preparation reveals that outer cyst walls represent negligible contaminants. The ultrastructure of these isolated nucleoli examined with transmission electron microscopy is found to be identical with that of nucleoli from whole cells, fixed in an identical manner. The 50 nucleolar proteins separated by SDS gel electrophoresis have been examined throughout the growth cycle of Acanthamoeba and into the strat of induced encystment, at which time 10 protein bands disappear, 11 bands are observed to decrease, and 8 are seen to increase in concentration. Phenol-soluble proteins are extracted from the nucleolus which correspond to 29 of the 50 nucleolar proteins, with 17 of these proteins corresponding to nucleolar proteins that change at the onset of encystment. Thes nucleolar proteins are also compared with those of rat liver nucleoli by gel electrophoresis, resulting in the observation that extremely few protein homologies exist between the two. Numerous quantitative and qualitative changes in the gel pattern of phenol-soluble nuclear proteins during early and late log phase growth and the onset of stationary phase were also observed.

Signal-mediated nuclear transport in the amoeba. (7/489)The evolutionary changes that occur in signal-mediated nuclear transport would be expected to reflect an increasing need to regulate nucleocytoplasmic exchanges as the complexity of organisms increases. This could involve changes in both the composition and structure of the pore complex, as well as the cytosolic factors that mediate transport. In this regard, we investigated the transport process in amoebae (Amoeba proteus and Chaos carolinensis), primitive cells that would be expected to have less stringent regulatory requirements than more complex organisms. Colloidal gold particles, coated with bovine serum albumin (BSA) conjugated with simple (large T) nuclear localization signals (NLSs), bipartite (nucleoplasmin) NLSs or mutant NLSs, were used to assay nuclear import. It was found that in amoebae (1) the diameter of the particles that are able to enter the nucleoplasm is significantly less than in vertebrate cells, (2) the simple NLS is more effective in mediating nuclear import than the bipartite NLS, and (3) the nucleoporins do not appear to be glycosylated. Evidence was also obtained suggesting that, in amoebae, the simple NLS can mediate nuclear export. (+info)
Visualization of actin fibers associated with the cell membrane in amoebae of Dictyostelium discoideum. (8/489)Amoebae of Dictyostelium discoideum were attached to a surface coated with polylysine, and the upper portion of the cells was sheared off with a stream of buffer. Scanning and transmission electron microscopy showed that the cytoplasmic surface of the exposed membrane was covered with fibers consisting of actin-containing filaments. The actin was identified by its solubility properties and its ability to interact with muscle myosin. (+info)
Amoeba proteus gets its name through two Greek words; Amoeba meaning change and proteus meaning Sea God. The Greek meaning describes this microbe as the Sea God Proteus that has an ever changing shape. Its ability to change shape is from the pseudopodia, which are common in eukaryotic microbes. The pseudopodia grants the microbe an ability to extend and contract in any shape possible. This extending and contracting is from the reversible assembly of actin sub-unites into microfilaments. Contraction is caused by the filaments near the cells end interact with myosin. While extension is caused by the actin reassembling itself back into its body. This is how the Amoeba proteus moves around.  Other than its pseudopodia, the Amoeba proteus can be described as unicellular, colorless, or transparent. The average size of an Amoeba proteus varies around from .2 to .3 mm in diameter but larger forms have been found measuring up to .5 mm in diameter which is visible to the eye.  Amoeba proteus ...

Amoebas are published as making food choices as a response to their environment. Like human lymphocytes amoebas surround cytes then digest them. Creating amoebas that are immunotransparent to the human immune system permits them to circulate absent immune attack from the body; creating immunotransparency is a strategy employed with nonhuman mammals thus breeding an immunotransparent amoeba may be literally millions or billions of times easier. Amoebas are publishes as making food choice comparisons; it is possible to make them tissue type specific or possibly even educated to prefer a diseased tissue type specific to a particular person.. The amoebas can be bred or trained to recognize then eat tissue types with particular surface chemistry such as cancer cytes or atherosclerotic lesions. The amoebas literally attack diseased tissue like a second immune system. artherosclerosis as well as cancer were the two most lethal diseases of the 20th century. amoebas that eat cholesterol plaques as well ...
A study published in Nature Communications from researchers at the University of Geneva and Baylor College of Medicine show the amoeba Dictyostelium discoideum uses antimicrobial defense systems akin to phagocytes of the human innate immune system, and it evolved these defenses much earlier than initially thought.. D. discoideum is a soil living amoeba often referred to as "slime mold". These social amoebas tend to aggregate together, particularly during times of low resources, to form a mobile "slug" composed of ~100,000 individual amoebas. The slugs role is to disperse spores on the wind to seed new areas containing better resources. Within this slug, 80% of the amoeba will become spores, while approximately 20% will sacrifice themselves to form a stalk, a primitive spore dispersal method. About 1% of the amoeba though takes on defense duties by protecting the stalk/spore dispersion mechanism from invading bacteria.. It is this 1% that the researchers were interested in. Termed "sentinel ...
Naegleria cant live in salt water. It cant survive in properly treated swimming pools or in properly treated municipal water.. Most cases of N. fowleri disease occur in Southern or Southwestern states. Over half of all infections have been in Florida and Texas.. How Do People Get Infected With Brain-Eating Amoeba?. The term "brain-eating amoeba" makes the amoeba sound like a tiny zombie stalking your skull. But brains are accidental food for them.. According to the CDC, N. fowleri normally eats bacteria. But when the amoeba gets into humans, it uses the brain as a food source.. The nose is the pathway of the amoeba, so infection occurs most often from diving, water skiing, or performing water sports in which water is forced into the nose. But infections have occurred in people who dunked their heads in hot springs or who cleaned their nostrils with neti pots filled with untreated tap water.. A person infected with N. fowleri cannot spread the infection to another person.. How Do Amoebas Get in ...

Free-living Amoebae are unicellular protozoans common in aquatic ecosystems, which are also known to colonize Human created water systems such as water supply systems and swimming pools. Whilst in some ways these organisms can be helpful, consuming a range of Bacterial, Viral and Fungal pathogens, they have also been shown to cause a range of infections themselves, and can themselves be infected by a variety of pathogenic Bacteria, such as Legionella pneumophila, Mycobacteria, Pseudomonas aerugionosa and Acinetobacter baumannii. Whilst most Bacteria are consumed and digested by the Amoebae, these pathogenic species have been shown to be able to resist digestion, instead surviving within the Amoebae, where they receive protection from biocides and antibiotics, later emerging to cause infections in Humans. ...

Scientists used to think amoebas had always produced asexually, but it turns out a long time ago, there were mommy amoebas and daddy amoebas, and when they loved each other very, very much, you got little baby amoebas. After a few million years or so, however, the amoebas decided it just wasnt worth the effort and it made a lot more sense reproducing without getting into the whole, "You forgot our anniversary" and "do these vacuoles make my protist look fat?" thing. What this means is, while we used to believe that sexual reproduction represented an advance over asexual, in fact, its the other way around. This news is disappointing to the rest of us who still view sex as at least mildly entertaining, but maybe when youve been on the planet as long as amoeba have, you start to see things differently ...
Free-living amoebae (FLA) are parasites within both humans and animals causing a wide range of symptoms and act as hosts of, and vehicles for phylogenetically diverse microorganisms, called endocytobionts. The interaction of the FLA with sympatric microorganisms leads to an exceptional diversity within FLA. Some of these bacteria, viruses, and even eukaryotes, can live and replicate intracellularly within the FLA. This relationship provides protection to the microorganisms from external interventions and a dispersal mechanism across various habitats. Among those intracellularly-replicating or -residing organisms there are obligate and facultative pathogenic microorganisms affecting the health of humans or animals and are therefore of interest to Public Health Authorities. Mimiviruses, Pandoraviruses, and Pithoviruses are examples for interesting viral endocytobionts within FLA. Future research is expected to reveal further endocytobionts within free-living amoebae and other protozoa through co
Amoeba starts the game by making its sound and movement. After that Amoeba makes sound and movement of some other animal in the game. For example a horse. Then player of the horse role has to reply by horses sound and movement and then make some other animal routines etc. If the horse does not notice its turn or makes wrong sounds or movements player falls back in the evolution and becomes an amoeba. All other players rise a step in the evolution eg. leader (former amoeba) becomes a fish and the ex-fish becomes a mouse etc. New amoeba then starts the game again. Sounds and movements remain the same. ...

This class was anticipated by some biologists like Jahn, who grouped all amoebae with granular pseudopodia together, but most split the lobose amoebae into testate Testacealobosia and naked Gymnamoebia. These latter are polyphyletic, but molecular trees by Bolivar et al. identified a core monophyletic subgroup. Subsequent studies showed the testate lobose amoebae belong to the same group, which was thus renamed Lobosea sensu stricto or Tubulinea.. ...
Living Free, cosmopolitan amoebae from genus present a serious risk to human health. viruses, fungi, and protist. However, their anti-amoebic potential has not been fully tested yet. The aim of this study was to assess silver nanoparticles (AgNPs) and platinum nanoparticles (PtNPs) anti-amoebic activity and influence on the amoebae adhesion to the surface of four different groups of contact lensesclassified according to the Food and Drugs Administration (FDA) guidelines. The obtained results show that both tested nanoparticles were effective against trophozoites and decreased the amoebae adhesion to the contact lens surface. AgNPs demonstrated better anti-amoebic activity to cytotoxicity dependence and decreased amoebae adhesion within a wider spectral range of the examined contacts. Our research also verified that ionization following to hydration from the contact lens materials is an essential parameter influencing the adhesion towards the contact lens surface area. In conclusion, gold ...
A new species of naked amoeba, Platyamoeba pseudovannellida n.sp., is described on the basis of light microscopic and fine structural features. The amoeba was isolated from the Salton Sea, California, from water at a salinity of ca. 44parts per thousand, Locomotive amoebae occasionally had a spatulate outline and floating cells had radiating pseudopodia, sometimes with pointed tips. Both these features are reminiscent of the genus Vannella. However, the surface coat (glycocalyx) as revealed by TEM indicates that this is a species of Platyamoeba. Although salinity was not used as a diagnostic feature, this species was found to have remarkable tolerance to fluctuating salinity levels, even when changes were rapid. Amoebae survived over the range 0parts per thousand to 150parts per thousand, salt and grew within the range 0parts per thousand to 138parts per thousand salt. The generation time of cells averaged 29 h and was not markedly affected by salt concentration. This is longer than expected for ...
This chapter summarizes the available information on amoeba-fungus interactions and speculates on the origins of fungal virulence for mammalian hosts. Other organisms such as slime molds have ameboid cells that behave like amoebae in movement and feeding. Amoebae and slime molds are grouped under the kingdom Protozoa. Various studies have reported specific types of interactions and responses when amoebae and fungi are brought into contact in the laboratory. Amoeba phagocytosis can be induced by arachidonic acid and prostaglandins, a phenomenon that may be highly relevant to fungus-amoeba interactions since many species of fungi produce arachidonic acid derivatives and prostaglandins. Although each of these observations was made under artificial laboratory conditions, they suggest certain specificity to amoeba-fungus interactions that buttresses the argument that these two types of organisms frequently interact in the environment. In the late 1990s, the author revisited the question of amoeba-fungus
In material collected from Tannoch Loch, Dunbartonshire, a large free-living, hitherto undescribed amoeba was found. Individual specimens vary in length from 420 to 500µ and in width from 70 to 140µ. Viewed over a black background this amoeba looks dense, white, and opaque, while in transmitted light it has a dusky, almost black, hue, due to the presence in the endoplasm of a large number of small crystals uniform in size, slender and pointed at both ends. There is always a uroid at the hinder end surrounded by bits of debris. The one large nucleus is without a karyosome but has masses of chromatin scattered through the nuclear substance. As a rule there is only one large contractile vacuole, but occasionally a few small ones may be seen at the hinder end. A certain number of nutritive spheres are always present.

Rivka Bracha and colleagues in the lab of Prof. David Mirelman in the Biological Chemistry Department had shown that expression of the gene coding for the toxic protein could be prevented by inserting a plasmid (a small loop of DNA) containing a copy of a specific part of that gene into the amoeba cell nucleus. Introducing the plasmid led to the modification of DNA "packing" proteins, causing the DNA-protein packages to become more tightly coiled - something like a tangled telephone cord - and causing an irreversible silencing of gene expression. In a recent paper published in PLoS Pathogens, the Weizmann scientists report the silencing of two additional virulence genes in the same amoebae using a similar plasmid-induced principle. The disabled amoebae, though rendered harmless, still display the same repertoire of surface antigens (markers recognized by the immune system) as the disease-causing strain. The scientists now plan to test the ability of these silenced amoebae to serve as a live ...
Aono et al. Royal Society Open Science). To make sure the amoeba entered the cities in an optimal way, the researchers used light (which the amoeba doesnt like) to illuminate certain channels that were too far apart or that it had already visited, and to stop it from entering several channels simultaneously.. To the teams astonishment, it didnt take exponentially longer for the amoeba to figure out a reasonable (nearly optimal) way to enter eight different channels than it did to enter four, despite the increase in the number of possible configurations.. "Interestingly," the team added, "the quality of the solution does not degrade despite the explosive expansion of the search space.". To be fair, conventional computers are pretty slick, and they can also solve the problem in linear time as it gets exponentially harder.. But they actually do it in a completely different way - the amoeba was constantly testing new body shapes at a constant rate and processed optical feedback at the same ...

Liver abscesses are always preceded by intestinal colonization, which may be asymptomatic. Blood vessels may be compromised early by wall lysis and thrombus formation. Trophozoites invade veins to reach the liver through the portal venous system. E. histolytica is resistant to complement-mediated lysis-a property critical to survival in the bloodstream. In contrast, E. dispar is rapidly lysed by complement and is thus restricted to the bowel lumen. Inoculation of amebas into the portal system of hamsters results in an acute cellular infiltrate consisting predominantly of neutrophils. Later, the neutrophils are lysed by contact with amebas, and the release of neutrophil toxins may contribute to necrosis of hepatocytes. The liver parenchyma is replaced by necrotic material that is surrounded by a thin rim of congested liver tissue.The necrotic contents of a liver abscess are classically described as "anchovy paste," although the fluid is variable in color and is composed of bacteriologically ...

I thought todays Friday Science entry would be about my favorite amoebae and yesterdays seminar speaker. My boss was the seminar host for yesterday and she invited Dr. Adam Kuspa to speak about his current research with Dictyostelium (Dicty), the same organism we work with. Dicty are a soil amoeba that eats things like bacteria and yeast. They crawl around in the ground individually hunting for food and dividing until they run out of food. Then all the dicty cells in that area migrate together to form a slug (but not the kind of slug that leave the slime trails on your side walk). We are talking about 50,000 cells coming together and moving through the soil until they find a good spot to sort of plant themselves, usually some place kind of sunny. Then they form a stalk with a fruiting body on the end. The fruiting body is full of spores and when the food source returns or conditions are good, the spores can germinate back into single dicty cells. Pretty cool.. There are certain dicty cells in ...
Amoeboid motility requires spatiotemporal coordination of biochemical pathways regulating force generation and consists of the quasi-periodic repetition of a EPZ-6438 motility cycle driven by actin polymerization and actomyosin contraction. tensional stress and that wild-type cells develop two opposing EPZ-6438 "pole" forces pulling the front and back toward the center whose strength is modulated up and down periodically in each cycle. We demonstrate that nonmuscular myosin II complex (MyoII) cross-linking and motor functions have different roles in controlling the spatiotemporal distribution of traction forces the changes in cell shape and the duration of all the phases. We show that the time required to complete each phase is dramatically increased in cells with altered MyoII motor function demonstrating that it is required not only for contraction but also for protrusion. Concomitant loss of MyoII actin cross-linking leads to a force redistribution throughout the cell perimeter pulling inward ...

They started selling their line of products in 2009 and have a good reputation ever since. Majority of their guns can be upgraded with their own line of parts. The Octarms rail system uses the keymod system with slots on the 3, 6, 9 and 12 oclock portion of the rail. ARES have also released the rail system individually with many additional accessories one can apply to it. It shoots at a steady 410 FPS which is a great outdoor gun to use, tested with a 7.4V Large Tamiya type of battery. Though it probably can take 11.1V we dont suggest it till you change the internal parts to be able to cope with increased pressure. Firing modes this gun has are are ...
