An evaluation of elongation factor 1 alpha as a phylogenetic marker for eukaryotes. (1/73)

Elongation factor 1 alpha (EF-1 alpha) is a highly conserved ubiquitous protein involved in translation that has been suggested to have desirable properties for phylogenetic inference. To examine the utility of EF-1 alpha as a phylogenetic marker for eukaryotes, we studied three properties of EF-1 alpha trees: congruency with other phyogenetic markers, the impact of species sampling, and the degree of substitutional saturation occurring between taxa. Our analyses indicate that the EF-1 alpha tree is congruent with some other molecular phylogenies in identifying both the deepest branches and some recent relationships in the eukaryotic line of descent. However, the topology of the intermediate portion of the EF-1 alpha tree, occupied by most of the protist lineages, differs for different phylogenetic methods, and bootstrap values for branches are low. Most problematic in this region is the failure of all phylogenetic methods to resolve the monophyly of two higher-order protistan taxa, the Ciliophora and the Alveolata. JACKMONO analyses indicated that the impact of species sampling on bootstrap support for most internal nodes of the eukaryotic EF-1 alpha tree is extreme. Furthermore, a comparison of observed versus inferred numbers of substitutions indicates that multiple overlapping substitutions have occurred, especially on the branch separating the Eukaryota from the Archaebacteria, suggesting that the rooting of the eukaryotic tree on the diplomonad lineage should be treated with caution. Overall, these results suggest that the phylogenies obtained from EF-1 alpha are congruent with other molecular phylogenies in recovering the monophyly of groups such as the Metazoa, Fungi, Magnoliophyta, and Euglenozoa. However, the interrelationships between these and other protist lineages are not well resolved. This lack of resolution may result from the combined effects of poor taxonomic sampling, relatively few informative positions, large numbers of overlapping substitutions that obscure phylogenetic signal, and lineage-specific rate increases in the EF-1 alpha data set. It is also consistent with the nearly simultaneous diversification of major eukaryotic lineages implied by the "big-bang" hypothesis of eukaryote evolution.  (+info)

Cloning, sequencing, and nucleolar targeting of the basal-body-binding nucleolar protein BN46/51. (2/73)

BN46/51 is an acidic protein found in the granular component of the nucleolus of the amebo-flagellate Naegleria gruberi. When Naegleria amebae differentiate into swimming flagellates, BN46/51 is found associated with the basal body complex at the base of the flagella. In order to determine the factors responsible for targeting BN46/51 to a specific subnucleolar region, cDNAs coding for both subunits were isolated and sequenced. Two clones, JG4.1 and JG12.1 representing the 46 kDa and 51 kDa subunits, respectively, were investigated in detail. JG12.1 encoded a polypeptide of 263 amino acids with a predicted size of 30.1 kDa that co-migrated with the 51 kDa subunit of BN46/51 when expressed in yeast. JG4.1 encoded a polypeptide of 249 amino acids with a predicted size of 28.8 kDa that co-migrated with the 46 kDa subunit of BN46/51. JG4.1 was identical to JG12.1 except for the addition of an aspartic acid between positions 94 and 95 of the JG12.1 sequence and the absence of 45 amino acids beginning at position 113. The predicted amino acid sequences were not closely related to any previously reported. However, the sequences did have 26-31% identity to a group of FKPBs (FK506 binding proteins) but lacked the peptidyl-prolyl cis-trans isomerase domain of the FKBPs. Both subunits contained two KKE and three KKX repeats found in other nucleolar proteins and in some microtubule binding proteins. Using 'Far Western' blots of nucleolar proteins, BN46/51 bound to polypeptides of 44 kDa and 74 kDa. The 44 kDa component was identified as the Naegleria homologue of fibrillarin. BN46/51 bound specifically to the nucleoli of fixed mammalian cells, cells which lack a BN46/51 related polypeptide. When the JG4.1 and JG12.1 cDNAs were expressed in yeast, each subunit was independently targeted to the yeast nucleolus. We conclude that BN46/51 represents a unique nucleolar protein that can form specific complexes with fibrillarin and other nucleolar proteins. We suggest that the association of BN46/51 with the MTOC of basal bodies may reflect its role in connecting the nucleolus with the MTOC activity for the mitotic spindle. This would provide a mechanism for nucleolar segregation during the closed mitosis of Naegleria amebae.  (+info)

Expression of the Naegleria intron endonuclease is dependent on a functional group I self-cleaving ribozyme. (3/73)

NaSSU1 is a complex nuclear group I intron found in several species of Naegleria, consisting of a large self-splicing group I ribozyme (NaGIR2), which itself is interrupted by a small, group I-like ribozyme (NaGIR1) and an open reading frame (ORF) coding for a homing endonuclease. The GIR1 ribozyme cleaves in vitro transcripts of NaSSU1 at two internal processing sites about 400 nt downstream of the 5' end of the intron, proximal to the endonuclease ORF. Here we demonstrate that self-cleavage of the excised intron also occurs in vivo in Naegleria gruberi, generating an ORF-containing RNA that possesses a short leader with a sequence element likely to be involved in gene expression. To assess the functional significance of self-cleavage, we constructed a genetic system in Saccharomyces cerevisiae. First, a mutant yeast strain was selected with a mutation in all the rRNA genes, rendering the rDNA resistant to cleavage by the Naegleria endonuclease. Active endonuclease, which is otherwise lethal, could be expressed readily in these cells. Endonuclease activity also could be detected in extracts of yeast harboring plasmids in which the endonuclease ORF was embedded in its native context in the intron. Analysis of the RNA from these yeast cells showed that the excised intron RNA was processed as in N. gruberi. A mutant intron constructed to prevent self-cleavage of the RNA failed to express endonuclease activity. These results support the hypothesis that the NaGIR1-catalyzed self-cleavage of the intron RNA is a key event in expression of the endonuclease.  (+info)

Functional characterization of isoschizomeric His-Cys box homing endonucleases from Naegleria. (4/73)

Several species within the amoeboflagellate genus Naegleria harbor an optional ORF containing group I introns in their nuclear small subunit ribosomal DNA. The different ORFs encode homing endonucleases with 65 to 95% identity at the amino-acid level. I-NjaI, I-NanI and I-NitI, from introns in Naegleria jamiesoni, N. andersoni and N. italica, respectively, were analyzed in more detail and found to be isoschizomeric endonucleases that recognize and cleave an approximal 19-bp partially symmetrical sequence, creating a pentanucleotide 3' overhang upon cleavage. The optimal conditions for cleavage activity with respect to temperature, pH, salt and divalent metal ions were investigated. The optimal cleavage temperature for all three endonucleases was found to be 37 degrees C and the activity was dependent on the concentration of NaCl with an optimum at 200 mM. Divalent metal ions, primarily Mg2+, are essential for Naegleria endonuclease activity. Whereas both Mn2+ and Ca2+ could substitute for Mg2+, but with a slower cleavage rate, Zn2+ was unable to support cleavage. Interestingly, the pH dependence of DNA cleavage was found to vary significantly between the I-NitI and I-NjaI/I-NanI endonucleases with optimal pH values at 6.5 and 9, respectively. Site-directed mutagenesis of conserved I-NjaI residues strongly supports the hypothesis that Naegleria homing endonucleases share a similar zinc-binding structure and active site with the His-Cys box homing endonuclease I-PpoI.  (+info)

Identity of Naegleria strains isolated from organs of freshwater fishes. (5/73)

Eighteen Naegleria strains were isolated from organs of freshwater fishes belonging to 5 species. Morphometric study allowed the separation of the Naegleria strains from the non-vahlkampfiid amoeboflagellates, but was inadequate for species determination. Six strains, representatives of groups that had a slightly different cyst size, were selected and corresponding derived clones were subjected to sequence analysis and riboprinting restriction fragment length polymorphism (RFLP)-PCR analysis of the small subunit (SSU) rRNA genes. One strain isolated from the brain of a fish with systemic infection was characterised by an intronless 2 kb long SSU rRNA gene and was identified as N. australiensis. Another 5 strains had a 1.3 kb long group I intron in their SSU rRNA gene and, based on the SSU rRNA sequences and riboprints, RFLP-PCR patterns appeared in phylogenetic trees to be closely related to Naegleria clarki.  (+info)

Characterization of the self-splicing products of two complex Naegleria LSU rDNA group I introns containing homing endonuclease genes. (6/73)

The two group I introns Nae.L1926 and Nmo.L2563, found at two different sites in nuclear LSU rRNA genes of Naegleria amoebo-flagellates, have been characterized in vitro. Their structural organization is related to that of the mobile Physarum intron Ppo.L1925 (PpLSU3) with ORFs extending the L1-loop of a typical group IC1 ribozyme. Nae.L1926, Nmo.L2563 and Ppo.L1925 RNAs all self-splice in vitro, generating ligated exons and full-length intron circles as well as internal processed excised intron RNAs. Formation of full-length intron circles is found to be a general feature in RNA processing of ORF-containing nuclear group I introns. Both Naegleria LSU rDNA introns contain a conserved polyadenylation signal at exactly the same position in the 3' end of the ORFs close to the internal processing sites, indicating an RNA polymerase II-like expression pathway of intron proteins in vivo. The intron proteins I-NaeI and I-NmoI encoded by Nae.L1926 and Nmo.L2563, respectively, correspond to His-Cys homing endonucleases of 148 and 175 amino acids. I-NaeI contains an additional sequence motif homologous to the unusual DNA binding motif of three antiparallel beta sheets found in the I-PpoI endonuclease, the product of the Ppo.L1925 intron ORF.  (+info)

Use of multiplex PCR and PCR restriction enzyme analysis for detection and exploration of the variability in the free-living amoeba Naegleria in the environment. (7/73)

A multiplex PCR was developed to simultaneously detect Naegleria fowleri and other Naegleria species in the environment. Multiplex PCR was also capable of identifying N. fowleri isolates with internal transcribed spacers of different sizes. In addition, restriction fragment length polymorphism analysis of the PCR product distinguished the main thermophilic Naegleria species from the sampling sites.  (+info)

Cultivation of pathogenic and opportunistic free-living amebas. (8/73)

Free-living amebas are widely distributed in soil and water, particularly members of the genera Acanthamoeba and NAEGLERIA: Since the early 1960s, they have been recognized as opportunistic human pathogens, capable of causing infections of the central nervous system (CNS) in both immunocompetent and immunocompromised hosts. Naegleria is the causal agent of a fulminant CNS condition, primary amebic meningoencephalitis; Acanthamoeba is responsible for a more chronic and insidious infection of the CNS termed granulomatous amebic encephalitis, as well as amebic keratitis. Balamuthia sp. has been recognized in the past decade as another ameba implicated in CNS infections. Cultivation of these organisms in vitro provides the basis for a better understanding of the biology of these amebas, as well as an important means of isolating and identifying them from clinical samples. Naegleria and Acanthamoeba can be cultured axenically in cell-free media or on tissue culture cells as feeder layers and in cultures with bacteria as a food source. Balamuthia, which has yet to be isolated from the environment, will not grow on bacteria. Instead, it requires tissue culture cells as feeder layers or an enriched cell-free medium. The recent identification of another ameba, Sappinia diploidea, suggests that other free-living forms may also be involved as causal agents of human infections.  (+info)

Protists account for the bulk of eukaryotic diversity. Through studies of gene and especially genome sequences the molecular basis for this diversity can be determined. Evident from genome sequencing are examples of versatile metabolism that go far beyond the canonical pathways described for eukaryotes in textbooks. In the last 2-3 years, genome sequencing and transcript profiling has unveiled several examples of heterotrophic and phototrophic protists that are unexpectedly well-equipped for ATP production using a facultative anaerobic metabolism, including some protists that can (Chlamydomonas reinhardtii) or are predicted (Naegleria gruberi, Acanthamoeba castellanii, Amoebidium parasiticum) to produce H(2) in their metabolism. It is possible that some enzymes of anaerobic metabolism were acquired and distributed among eukaryotes by lateral transfer, but it is also likely that the common ancestor of eukaryotes already had far more metabolic versatility than was widely thought a few years ago. ...
I keep reading the information about it and I have come to the conclusion that this amoeba is everywhere. Thing is the disease it causes is really rare (PAM). I also read where 2 kids last month died from this while swimming in lakes.

We propose a general theory of clonal reproduction for parasitic protozoa, which has important medical and biological consequences. Many parasitic protozoa have been assumed to reproduce sexually, because of diploidy and occasional sexuality in the laboratory. However, a population genetic analysis of extensive data on biochemical polymorphisms indicates that the two fundamental consequences of sexual reproduction (i.e., segregation and recombination) are apparently rare or absent in natural populations of the parasitic protozoa. Moreover, the clones recorded appear to be stable over large geographical areas and long periods of time. A clonal population structure demands that the medical attributes of clones be separately characterized; ubiquitous clones call for priority characterization. Uniparental reproduction renders unsatisfactory Linnean taxonomy; this needs to be supplemented by the natural clone as an additional taxonomic unit, which is best defined by means of genetic markers.. ...

Naegleria fowleri, colloquially known as the brain-eating amoeba, is a species of the genus Naegleria, belonging to the phylum Percolozoa. It is a free-living, bacteria-eating amoeba that can be pathogenic, causing a fulminant (sudden and severe) brain infection called naegleriasis, also known as primary amoebic meningoencephalitis (PAM). This microorganism is typically found in bodies of warm freshwater, such as ponds, lakes, rivers, and hot springs. It is also found in the soil near warm-water discharges of industrial plants, and in unchlorinated or minimally-chlorinated swimming pools. It can be seen in either an amoeboid or temporary flagellate stage. Naegleria fowleri is a thermophilic (heat-loving), free-living amoeba. It is found in warm and hot freshwater ponds, lakes and rivers, and in the very warm water of hot springs. As the water temperature rises, its numbers increase. The amoeba was identified in the 1960s in Australia but appears to have evolved in the United States. N. fowleri ...

A Naturally-occurring Organism. Naegleria fowleri is a naturally-occurring single-celled organism that lives in fresh, warm waters, such as lakes, rivers, ponds and hot springs, and soil. (It also can be found in water distribution systems and hot water heaters.) The most common months of exposure are July and August when bodies of water are the warmest. Adults and children enjoying these outdoor venues may be vulnerable if water enters the nose when jumping or diving into water and during underwater recreation. When water harboring Naegleria enters the nasal passages, the amoeba may travel along the olfactory nerve to the brain, where it destroys brain tissue and causes brain swelling known as primary amebic meningoencephalitis (PAM), and death. Neti pot use for sinus cleansing also has been associated with Naegleria infections, and tap water (especially warmed with water from the hot tap) should never be used in neti pots without first boiling it. Symptoms of infection usually begin within ...

Background: Primary amoebic meningoencephalitis (PAM) is a rare but fatal infection caused by Naegleria fowleri. The infection is acquired by deep nasal irrigation with infected water. Patients present with signs and symptoms similar to pneumococcal meningitis, leading to delayed diagnosis and treatment and hence high mortality. Methods: We conducted a case-control study comparing culture proven cases of PAM with pneumococcal meningitis presenting to our center between April 2008 and September 2014. Only patients with blood and/or cerebrospinal fluid cultures positive for Streptococcus pneumoniae during the same time period were included for comparison. Results: There were 19 cases of PAM and pneumococcal meningitis, each. When comparing PAM with pneumococcal meningitis, patients with PAM were more likely to be male (89.5 vs. 36.8 %), younger (mean age: 30 vs. 59 years), present with seizures (42.1 vs. 5.3 %). Both groups of patients presented with similar vital signs and there were no remarkable

The two reported cases of kids in the U.S. contracting the Naegleria fowleri parasite this summer has parents around the country wanting to know more about the often fatal brain-eating amoeba.
Naegleria fowleri is a free living amoebae that can be an opportunistic pathogen, and in some cases, has been diagnosed as the causative agent of the ...
Naegleria fowleri biologically belongs to kingdom Protista, also known as the brain-eating amoeba. is commonly found as an amoeba or as a free flagellum in warm lakes, hot springs as well as in fresh water reservoirs such as rivers, ponds and unchlorinated swimming pools. Since Naegleria fowleri is a heat tolerant (thermophilic) protist, it thrives during summer when temperatures are high. The organism gains access to the human brain through the nostrils while washing face, swimming or performing ritual ablution and even while drinking water. It then pierces the cribriform plate to enter central nervous system where it causes granulomatous inflammation leading to primary amoebic meningoencephalitis. Heres when Unilever Pureit comes into play.. How does it affect you? Karachi being a subtropical region, predominantly has a warm climate which provides a favorable ecological niche for this organism to occupy. The first case of Naegleria fowleri was reported in Pakistan in 2008. Since then maximum ...

The next time you dive into a freshwater environment, you may want to cover your nose as a safety precaution. Common to lakes, rivers, and other freshwater environments, Naegleria fowleri is an amoeba that actually ingests brain matter.. Upon entering the nose, the amoeba travels through the olfactory nerves until it reaches the brain, where it feeds. Although its usual diet includes bacteria, that particular type of food is severely lacking in our brains. So Naegleria fowleri switches to actually eating our brains instead. Although natural bodies of water are common sources of this amoeba, contaminated pools or tap water may also harbor this zombie pathogen. It is important to know that contaminated water must pass through the nose for infection to occur. Infection cannot happen if the amoeba is ingested through the mouth or any other body openings. Infection by Naegleria fowleri is rare but almost always leads to death when it occurs. Currently, there is no standard drug used to treat this ...

She helps women with PCOS manage their symptoms by changing the way that they eat to address the core of the problem - PCOS - so that they can live their lives to.
Although millions of Japanese bathe in onsens every year with few noticeable side effects, there are still potential side effects to onsen usage, such as aggravating high blood pressure or heart disease.[13] Legionella bacteria have been found in some onsens with poor sanitation.[14][15] Revelations of poor sanitary practices at some onsens have led to improved regulation by hot-spring communities to maintain their reputation.[16] There have been reports of infectious disease found in hot bodies of water worldwide, such as various Naegleria species.[17] While studies have found the presence of Naegleria in hot spring waters, the worrisome Naegleria fowleri amoeba has not been identified.[17] Nevertheless, fewer than five cases have been seen historically in Japan, although not conclusively linked to onsen exposure.[18] Many onsens display notices reminding anyone with open cuts, sores, or lesions not to bathe. Additionally, in recent years onsens are increasingly adding chlorine to their waters ...

We investigated if intranasal immunization with amoebic lysates plus cholera toxin modified the populations of T and B lymphocytes, macrophages and dendritic cells by flow cytometry from nose-associated lymphoid tissue (NALT), cervical lymph nodes (CN), nasal passages (NP) and spleen (SP). In all immunized groups, the percentage of CD4 was higher than CD8 cells. CD45 was increased in B cells from mice immunized. We observed IgA-antibody forming cell (IgA-AFC) response, mainly in NALT and NP. Macrophages from NP and CN expressed the highest levels of CD80 and CD86 either in N. fowleri lysates with CT or CT alone immunized mice whereas dendritic cells expressed high levels of CD80 and CD86 in all compartment from immunized mice. These were lower than those expressed by macrophages. Only in SP from CT immunized mice these costimulatory molecules were increased. These results suggest that N. fowleri and CT antigens are taking by APCs and therefore, protective immunity depends on interactions between ...
Naegleria fowleri is just one of more than 20 Naegleria species found in the environment, but to date it is the only one found in human cases of PAM. Whats so special about N. fowleri? Perhaps it has something to do with N. fowleri being a thermophile - in other words it loves warmth. It can survive at temperatures as high as 45ºC, which would make it very comfortable at a normal human body temperature, and impervious to the highest fever. But many of the other species like high temperatures as well, so thats not the whole answer ...
The definitive diagnosis of N. fowleri is the detection of mobile trophozoites in a fresh sample of cerebrospinal fluid (CSF). Movement is rapid and directional. Their size varies from 10 to 25 microns. Cysts and the flagellate stage are not seen in CSF or other body tissues. The CSF may vary in color from a grayish to yellowish white. An increase in both red and white blood cells (predominately polymorphonuclear neutrophils) may be seen as the disease progresses, as well as an increase in protein and a decrease in glucose concentrations. The amoebae may be distinguished from other host cells by the large, round, central nucleolus ...
NEW ORLEANS (AP) - While officials try to pin down the source of a deadly amoeba found in the water supply of a suburban New Orleans community, bottled water sales in St. Bernard Parish have skyrocketed and some people worry about washing their faces in the shower. The state Department of Health and Hospitals on Thursday tried to dispel common myths and rumors about the amoeba Naegleria fowleri (nuh-GLEE-ree-uh FOW-ler-eye) - starting with the notion that the parish water isnt safe to drink. The worries began Sept. 12, when the state health department reported that parish water in Violet and Arabi tested positive for the amoeba that had killed a 4-year-old Mississippi boy in August after he visited St. Bernard Parish Jonathan Yoder, an epidemiologist in the Center for Disease Control and Preventions waterborne disease prevention branch, said Naegleria has never before been found in water treated by a U.S. water system. [...] each of the earlier cases, Yoder said the amoeba was found in the
Laboratory diagnosis is simple for PAM caused by Naegleria fowleri. CSF analysis usually reveals hypoglycorrhachia, high protein content, and high neutrophilic pleocytosis. Cells may easily be missed on routine cell count on hemacytometers as the diluting fluid used for cell counts is toxic to amoebae. When a diagnosis is suspected, a simple wet film of the CSF without centrifugation (which destroys amoebae) usually reveals motile amoebic trophozoites. Naegleria fowleri moves sluggishly by means of rounded lobopodes/ psuedopods (Figure 1). Cysts are not visible on CSF films; however, brain biopsy samples usually reveal both cysts and trophozoites.. The amoebae also exist in a flagellar form. CSF samples can be directly suspended in distilled water and incubated for 30 minutes to demonstrate rapidly motile flagellar forms. This may further confirm the diagnosis. Isolation of amoebae is possible in culture on non-nutrient agar covered with a lawn of E.coli. Growth can be seen within the next 48 ...
Like many others, I used water right out of the tap in my neti pot. After reading an article in the October issue of WC&P Magazine and information on the CDC website, thats not a recommended practice. While extremely rare, there is a risk of infection from Naegleria fowleri, a dangerous waterborne ameba commonly found in warm freshwater, in neti pot use with tap water. According to the WC&P article, conventional water treatment is effective against the ameba, but treated tap water and associated storage containers are not sterile. Under the right conditions, ameba and bacteria begin to regrow and can quickly reach high levels of contamination. Naegleria fowleri is not harmful when ingested, but can be fatal when forced into nasal passages where it has easy access to brain tissue. ...

Technically not an actual amoeba, Naegleria fowleri is an amoeboid eukaryotic protist that is usually found in freshwater environments. Moreover, this organism has an affinity for warm water, and it has been found in water as hot as 45°C. Hence, thermally polluted water bodies, such as industrial runoffs and powerplants, provide favorable breeding grounds. Therefore, it is advisable to seek suitable control measures of water pollution to prevent the risk of infections.. Naegleria cannot survive in environments with high salinity. It cannot live in chlorinated water as well. This organism is colloquially known the brain-eating amoeba because it can enter through the nose and start feeding on the brain. During harsh conditions, the protist reverts to a cyst form; it is dormant, but resilient to many environmental factors, which would otherwise kill the organism. Harsh conditions include a shortage of nutrients, desiccation, cold temperatures, and overcrowding. When favorable conditions return, ...
Its an extremely rare disease caused by the amoeba Naegleria fowleri and is typically found in freshwater ponds or lakes or in soil.

Three people have died this year from a rare brain infection caused by an amoeba, called Naegleria Fowleri, which feasts on neurons.. CNNs affiliate WFTV reports that a 16-year-old died Saturday in Brevard County, Florida, who may have been swimming in a river before falling victim to the amoeba. Another victim, according to the Richmond Times Dispatch, was a 9-year-old in Henrico County, Virginia, whose mother said he attended a fishing day camp the week before he died.. Jonathan Yoder, the waterborne disease and outbreak surveillance coordinator at the CDC told CNN, These are rare infections, but super tragic for families. We dont want to minimize how hard it is for families.. The symptoms of the infection mimics that of the more common bacterial meningitis. Symptoms include headache, fever, nausea, vomiting and neck stiffness. Later on the victim develops confusion, lack of attention to people and surroundings, loss of balance, seizures and hallucinations.. In order to catch the infection ...

Bad Thing #1: On the heels of the recent flurry of stories pertaining to Naegleria fowleri, methicillin-resistant staphylococcus aureus (henceforth MRSA) has been making waves in newspapers across the country. According to a story by The Washington Posts Rob Stein, United States health officials have reported that MRSA causes more life-threatening infections than public-health authorities had thought and is killing more people in the United States each year than AIDS. In fact, the Centers for Disease Control and Prevention have stated that [t]he microbe - a strain of a once innocuous staph bacterium that has become invulnerable to first-line antibiotics, is responsible for more than 94,000 serious infections and nearly 19,000 deaths each year. Stein continues ...
