Unusually high evolutionary rate of the elongation factor 1 alpha genes from the Ciliophora and its impact on the phylogeny of eukaryotes. (1/483)

The elongation factor 1 alpha (EF-1 alpha) has become widely employed as a phylogenetic marker for studying eukaryotic evolution. However, a disturbing problem, the artifactual polyphyly of ciliates, is always observed. It has been suggested that the addition of new sequences will help to circumvent this problem. Thus, we have determined 15 new ciliate EF-1 alpha sequences, providing for a more comprehensive taxonomic sampling of this phylum. These sequences have been analyzed together with a representation of eukaryotic sequences using distance-, parsimony-, and likelihood-based phylogenetic methods. Such analyses again failed to recover the monophyly of Ciliophora. A study of the substitution rate showed that ciliate EF-1 alpha genes exhibit a high evolutionary rate, produced in part by an increased number of variable positions. This acceleration could be related to alterations of the accessory functions acquired by this protein, likely to those involving interactions with the cytoskeleton, which is very modified in the Ciliophora. The high evolutionary rate of these sequences leads to an artificial basal emergence of some ciliates in the eukaryotic tree by effecting a long-branch attraction artifact that produces an asymmetric topology for the basal region of the tree. The use of a maximum-likelihood phylogenetic method (which is less sensitive to long-branch attraction) and the addition of sequences to break long branches allow retrieval of more symmetric topologies, which suggests that the asymmetric part of the tree is most likely artifactual. Therefore, the sole reliable part of the tree appears to correspond to the apical symmetric region. These kinds of observations suggest that the general eukaryotic evolution might have consisted of a massive radiation followed by an increase in the evolutionary rates of certain groups that emerge artificially as early branches in the asymmetric base of the tree. Ciliates in the case of the EF-1 alpha genes would offer clear evidence for this hypothesis.  (+info)

Ultrastructure of meiosis-inducing (heterotypic) and non-inducing (homotypic) cell unions in conjugation of Blepharisma. (2/483)

Cells of mating types I and II of Blepharisma japonicum interact with each other and unite in heterotypic (type I-type II) or homotypic (type I-type I, type II-type II) pairs. Heterotypic pairs undergo meiosis and other nuclear changes of conjugation, while homotypic pairs remain united for days without the nuclear changes taking place. We compared cell unions of these two kinds of pairs at the ultrastructural level. In the homotypic union, cell membranes are closely juxtaposed, separated by a distance of about 20 nm. This arrangement is interrupted in some places by vacuoles and small cytoplasmic bridges. Saccule-like structures tend to be more abundant near the united surfaces. Microtubules running at right or slightly obtuse angles with the cell surface (PACM microtubules) are characteristically present at the united region of cells. These structures are very similar to those observed in earlier stages of the heterotypic union. However, in homotypic pairs, cells unite only at the anterior half of the peristome, while in heterotypic pairs cells unite also at the posterior half of the peristome, where the cell membrane totally disappears in later stages. PACM microtubules persist for at least 18 h in homotypic unions, while they disappear within a few hours in heterotypic unions. These differences between the two kinds of cell union are discussed in relation to the initiation mechanism of meiosis and other nuclear changes of conjugation. Similarities between homotypic union and cell junctions in multicellular organisms are also discussed.  (+info)

Dermatitis with invasive ciliated protozoa in dolphins that died during the 1987-1988 Atlantic Bottlenose Dolphin morbilliviral epizootic. (3/483)

Dermatitis with intradermal cilated protozoa was identified in 18 of 95 (19%) Atlantic Bottlenose Dolphins (Tursiops truncatus) that died during the 1987-1988 Atlantic-dolphin morbillivirus epizootic. The lesions were characterized by focally extensive suppurative and histiocytic dermatitis and cellulitis with ulceration and variable numbers of dermal and hypodermal ciliates. Vasculitis, thrombosis, and/or intravascular ciliates were rarely present. In one dolphin, there was an associated lymphadenitis with ciliates, and in another, bronchopneumonia with rare intrabronchiolar ciliates. Ten of the dolphins were female, and eight were male. The animals ranged in length from 148 to 260 cm. Eleven were from Virginia, four were from New Jersey, and three were from Florida. In 13 dolphins, results of immunohistochemical and/or polymerase chain reaction (PCR) tests were positive for morbillivirus infection. Results of immunohistochemical tests were negative in four dolphins that were not also tested with PCR. Results were also negative in one dolphin tested using both methods. Nine dolphins had concomitant bacterial, fungal, and/or other protozoal infections. Fourteen other dolphins with ciliate-associated dermatitis were identified from 414 Atlantic bottlenose dolphin cases (3%) archived at the Armed Forces Institute of Pathology. The incidence of dermatitis with invasive ciliates is much greater in dolphins that died during the 1987-1988 epizootic.  (+info)

Rumen ciliate protozoal fauna of native sheep, friesian cattle and dromedary camel in Libya. (4/483)

Rumen ciliate species and composition were surveyed on the native sheep, Friesian-cattle and dromedary (one-humped) camels kept in Libya. As a result of survey, 5 genera including 14 species with 5 formae in native sheep, 9 genera including 27 species with 6 formae in Friesian-cattle and 6 genera including 13 species and 7 formae in dromedary camels were identified. All of the ciliate species and their percentage composition detected from the Libyan sheep and cattle in this examination were similar to those found from corresponding animals in the other countries. Libyan camels lacked some peculiar ciliate species found from camels in the other countries, but had many cosmopolitan species common with those in the domestic ruminants, suggesting that ciliate faunae of camel are easily affected by the other domestic ruminants kept together. The ciliate density was estimated as 105/ml in every host species.  (+info)

Factors affecting the uptake and metabolism of soluble carbohydrates by the rumen ciliate Dasytricha ruminantium isolated from ovine rumen contents by filtration. (5/483)

A filtration technique is described whereby metabolically-active suspensions of Dasytricha ruminantium can be isolated from rumen contents with negligible contamination by bacteria or other protozoa. The effects of environmental factors and of the diurnal cycle of the rumen on the uptake and metabolism of soluble carbohydrates by these isolated cells were examined. The principal contribution of the protozoan metabolic end-products to the host ruminant is the supply of lactic, acetic and butyric acids during periods when soluble sugars are in excess.  (+info)

Anti-immunoglobulin antisera used in an ELISA to detect antibodies in barramundi Lates calcarifer to Cryptocaryon irritans. (6/483)

Immunoglobulins (Ig) in serum from barramundi vaccinated with bovine serum albumin (BSA) were purified by ammonium sulphate precipitation and affinity chromatography using BSA as the ligand. The BSA-binding activity of eluted putative Ig fractions was assessed by enzyme-linked immunosorbent assay (ELISA) before being pooled and characterised by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Double affinity purification did not improve the purity of the Ig preparation compared to single affinity purification. Barramundi Ig were injected into sheep to produce anti-Ig antisera which were assessed in an indirect ELISA as the secondary antibody to detect serum Ig in barramundi vaccinated with Cryptocaryon irritans theronts. Affinity-purified Ig induced a more specific reagent for use as secondary antibody in ELISA than did normal whole-barramundi sera. The heavy (H) chain of barramundi Ig had an apparent molecular weight of 70 kDa while that of the light (L) chain was 27 kDa in SDS-PAGE studies. Under non-reducing conditions 2 putative populations of Ig were identified, at 768 and 210 kDa. The N-terminal sequence of the barramundi Ig H chain showed 78% homology with channel catfish Ictalurus punctatus Ig H chain sequence.  (+info)

Graviresponses of certain ciliates and flagellates. (7/483)

Protozoa are eukaryotic cells and represent suitable model systems to study the mechanisms of gravity perception and signal transduction due to their clear gravity-induced responses (gravitaxis and gravikinesis). Among protists, parallel evolution for graviperception mechanisms have been identified: either sensing by distinct stato-organelles (e.g., the Muller vesicles of the ciliate Loxodes) or by sensing the density difference between the whole cytoplasm and the extracellular medium (as proposed for Paramecium and Euglena). These two models are supported by experiments in density-adjusted media, as the gravitaxis of Loxodes was not affected, whereas the orientation of Paramecium and Euglena was completely disturbed. Both models include the involvement of ion channels in the cell membrane. Diverse experiments gave new information on the mechanism of graviperception in unicellular systems, such as threshold values in the range of 10% of gravity, relaxation of the responses after removal of the stimulus, and no visible adaptation phenomena during exposure to hypergravity or microgravity conditions for up to 12 days.  (+info)

A subtelomeric DNA sequence is required for correct processing of the macronuclear DNA sequences during macronuclear development in the hypotrichous ciliate Stylonychia lemnae. (8/483)

During macronuclear differentiation in ciliated protozoa a series of programed DNA reorganization processes occur. These include the elimination of micronuclear-specific DNA sequences, the specific fragmentation of the genome into small gene-sized DNA molecules, the de novo addition of telomeric sequences to these DNA molecules and the specific amplification of the remaining DNA molecules. Recently we constructed a vector containing the modified micronuclear version of macronuclear destined DNA sequences that was correctly fragmented and telomeres were added de novo after injection into the developing macronucleus. It therefore must contain all the cis- acting sequences required for these processes. We made a series of vectors deleting different sequences from the original vector. It could be shown that at least in the case studied here no micronuclear-specific sequences are required for specific fragmentation of the genome and telomere addition. However, a short subtelomeric sequence at the 3[prime]-end is essential for these processes, whereas no specific cut seems to occur at the 5[prime]-end. In addition, we can show that the processing activity is restricted to a short period of time during macronuclear differentiation and that a preceding transcription is required for correct processing of macronuclear-destined DNA sequences. Possible mechanisms of these processes will be discussed.  (+info)

Isolated macronuclei from the hypotrichous ciliated protozoan Euplotes eurystomus incorporate biotinylated dUTP specifically into the replication band (RB) as detected with immunofluorescence, using rabbit anti-biotin antibodies followed by fluorescein-conjugated goat anti-rabbit IgG. When gold-conjugated goat anti-rabbit IgG was used in a preembedded reaction, subsequent immunoelectron microscopic analysis demonstrated that the biotinylated nucleotide appeared more concentrated in the rear zone of the RB, with almost no labeling in the forward zone. It was possible to use the immunofluorescent assay to establish that incorporation of biotinylated dUTP is inhibited by simultaneous addition of N-ethyl maleimide or aphidicolin, and by omission of any one of the other unlabeled dNTPs. In addition, prolonged heat shock of the intact cells, before lysis and in vitro assay, yielded markedly reduced incorporation. Comparison with published data on the in vivo incorporation of [3H]thymidine into ...

Hydrogenosomes are organelles that produce ATP and hydrogen, and are found in various unrelated eukaryotes, such as anaerobic flagellates, chytridiomycete fungi and ciliates. Although all of these organelles generate hydrogen, the hydrogenosomes from these organisms are structurally and metabolically quite different, just like mitochondria where large differences also exist. These differences have led to a continuing debate about the evolutionary origin of hydrogenosomes. Here we show that the hydrogenosomes of the anaerobic ciliate Nyctotherus ovalis, which thrives in the hindgut of cockroaches, have retained a rudimentary genome encoding components of a mitochondrial electron transport chain. Phylogenetic analyses reveal that those proteins cluster with their homologues from aerobic ciliates. In addition, several nucleus-encoded components of the mitochondrial proteome, such as pyruvate dehydrogenase and complex II, were identified. The N. ovalis hydrogenosome is sensitive to inhibitors of
Suspensions of Blepharisma intermedium were fed latex particles for 5 min and then were separated from the particles by filtration. Samples were fixed at intervals after separation and incubated to demonstrate acid phosphatase activity. They were subsequently embedded and sectioned for electron microscopy. During formation of the food vacuole, the vacuolar membrane is acid phosphatase-negative. Within 5 min, dumbbell-shaped acid phosphatase-positive bodies, possibly derived from the the acid phosphatase-positive Golgi apparatus, apparently fuse with the food vacuole and render it acid phosphatase-positive. A larger type of acid phosphatase-positive, vacuolated body may also fuse with the food vacuole at later stages. At about 20 min after formation, acid phosphatase-positive secondary pinocytotic vesicles pinch off from the food vacuoles and approach a separate system of membrane-bounded spaces. By 1 hr after formation, the food vacuole becomes acid phosphatase-negative, and the undigested latex ...
Target analysis is performed on previously published transient absorption spectra of the 200-kDa oxyblepharismin-binding protein (OBIP) thought to trigger the photophobic response of the ciliate Blepharisma japonicum. The OBIP sample is considered as heterogeneous and made of two distinct classes of chromophoreprotein complexes. A so-called nonreactive class is seen to be comparable to free oxyblepharismin in organic solution. Another, reactive, class is shown to undergo a fast picosecond photocycle involving the formation in 4 ps of an intermediate state noted Y1. The spectrum associated to Y1 bears striking similarities with that of the oxyblepharismin radical cation. This element favors the hypothesis that an excited-state intermolecular electron-transfer could be the primary step of the sensory transduction chain of B. japonicum. Proton release is also considered as a possible secondary step. These possibilities support the idea that reactive OBIP functions like an electron or proton pump. ...
Background:. Characterizing genome-scale data from diverse eukaryotes is essential for gene discovery and for inferring major transitions across the eukaryotic tree of life. Yet, the bulk of eukaryotic diversity remains undersampled, particularly for free-living microbial lineages. Analysis of transcriptome data generated from high throughput (e.g. 454) sequencing of mRNAs provides an efficient way to characterize genes from diverse eukaryotes.. Results:. Here we report analyses of RNA-Seq data from the rhizarian net-like amoeba Corallomyxa tenera, the ciliate Chilodonella uncinata and a recently-described genus representing a novel major clade of eukaryotes, Subulatomonas tetraspora. We generated 16,983, 11,529 and 10,630 contigs plus single reads for these taxa respectively. Given that these organisms cannot be cultured axenically, we developed custom scripts to remove bacterial contaminants through an iterative BLAST based protocol and we then identified expressed genes using BLAST2GO [1;2]. ...

In animals, sex pheromones indicate the availability of the female for breeding. Male animals may also emit pheromones that convey information about their species and genotype.. At the microscopic level, a number of bacterial species (e.g. Bacillus subtilis, Streptococcus pneumoniae, Bacillus cereus) release specific chemicals into the surrounding media to induce the competent state in neighboring bacteria.[18] Competence is a physiological state that allows bacterial cells to take up DNA from other cells and incorporate this DNA into their own genome, a sexual process called transformation.. Among eukaryotic microorganisms, pheromones promote sexual interaction in numerous species.[19] These species include the yeast Saccharomyces cerevisiae, the filamentous fungi Neurospora crassa and Mucor mucedo, the water mold Achlya ambisexualis, the aquatic fungus Allomyces macrogynus, the slime mold Dictyostelium discoideum, the ciliate protozoan Blepharisma japonicum and the multicellular green algae ...

Protists are a large group of diverse eukaryotic microorganisms, mainly unicellular animals and plants, that do not form tissues. Eukaryotes emerged in evolution more than 1.5 billion years ago.[6] The earliest eukaryotes were likely protists. Mating and sexual reproduction are widespread among extant eukaryotes including protists such as Paramecium and Chlamydomonas. In many eukaryotic species, mating is promoted by sex pheromones including the protist Blepharisma japonicum. Based on a phylogenetic analysis, Dacks and Roger[7] proposed that facultative sex was present in the common ancestor of all eukaryotes. However, to many biologists it seemed unlikely until recently, that mating and sex could be a primordial and fundamental characteristic of eukaryotes. A principal reason for this view was that mating and sex appeared to be lacking in certain pathogenic protists whose ancestors branched off early from the eukaryotic family tree. However, several of these protists are now known to be capable ...
The morphology and morphogenesis of the hypotrich ciliate Urosoma macrostyla (Wrześniowski, 1866) Berger, 1999, collected from a puddle in Harbin, China, were investigated using live observation and protargol impregnation. Based on previous and present studies, an improved diagnosis of U. macrostyla is supplied. It differs from its congeners mainly by the body shape, no cortical granules and number of macronuclear nodules. The ontogenesis of U. macrostyla is typical for species with such a somatic ciliary pattern: the oral primordium develops hypoapokinetally and FVT-anlagen develop in 5-streaks and primary mode. However, a unique characteristic in morphogenetic process is reported: anlagen for both the left and right marginal cirri occur de novo to the right of the parental structure which has never been seen in other oxytrichids. This characteristic was considered an apomorphy (Berger 1999). This indicates that U. macrostyla possibly has a high phylogenetic position within the genus Urosoma, ...

We tested the effect of increasing temperature while providing nutrient-replete conditions as well as the effect of ambient nutrient (N, P) deficiency. The results revealed different encystment cues and patterns in the three species. While depletion of ambient nitrogen and subsequent internal N stress were the primary factors behind cyst production of G. corollarium, higher temperature led to substantial encystment of S. hangoei and W. halophila without a direct link to cellular nutrient physiology. In W. halophila, N limitation induced a transition of the population to small cells presumably representing gametes, but this process was ...
The ciliate protozoa, Stentor and Paramecium, have been reported to escape from the bottom end of narrow capillary tubes into a larger volume of medium with increasing rapidity over the course of trials. This change in behavior has been considered an apparent example of associative learning. This decrease in escape time is not due to a change in the protozoas environment, their swimming speed, frequency of ciliary reversals, or the proportion of time spent forward or backward swimming. Instead, most of the decrease results from a decrease in the proportion of time spent in upward swimming. However, a similar decrease in upward swimming occurs when the task is altered to require escape from the upper end of the capillary tubes.

The composition of the group has remained largely unchanged since Faure-Fremiet (1950) included among holotrich ciliates, the suctorians, which had often not been included with the other ciliates by the specialists of the day (Corliss 1979). The classification of the group remained largely unchanged in the 20th century after Corliss (1961) formalized Faure-Fremiets conceptual vision, based primarily on the morphostatic morphology of the cells, derived from observation of the silver-stained ciliate cortex, and coupled with ontogenetic characters revealed through observation of division morphogenesis, and particularly stomatogenesis. Electron microscopy was just beginning as Corliss (1961) went to press. In the ensuing decades exploration of this new level of organization revealed a wealth of new characters for both cell biologists and systematists. These new data, accompanied by new ...

During macronuclear development in hypotrichous ciliated protozoans, several thousand macronuclear DNA molecules are amplified several-hundred fold. We investigated the regulation of this amplification by determining the copy numbers of three different macronuclear DNA molecules in the hypotrichous ciliate Euplotes crassus. Two of the macronuclear DNA molecules were present in approximately 1,000 copies per cell, while the third was present in approximately 6,500 copies per cell. These reiteration levels were achieved either during macronuclear development, or shortly thereafter, and were maintained during vegetative growth. The most abundant macronuclear DNA molecule is present as a single-copy sequence in the micronuclear genome. Thus, its high copy number results from differential amplification. These results indicate that DNA amplification during macronuclear development is regulated individually for each macronuclear DNA molecule.
Telomeric guanine-quadruplex DNA has been shown to form in vitro under physiological conditions (6-8). It has been suggested that this structure plays an important role in vivo in the protection of telomeric ends, and attempts have been made to use the guanine-quadruplex structure as a target for cancer therapy (12). However, until now, to the best of our knowledge, no experimental data exist that this structure actually occurs in the eukaryotic cell. We therefore decided to generate in vitro specific antibodies against the Oxytricha/Stylonychia telomeric guanine-quadruplex structure in the parallel conformation, using a synthetic antibody library and a cell-free selection and evolution system. The selected antibodies were applied for in situ localization of quadruplex DNA in the nuclei of the ciliated protozoan S. lemnae.. We selected our scFvs in vitro from a large synthetic library by ribosome display in six selection cycles. In RIA control experiments with a variety of competitors, we ...
I cannot answer these questions for you, but it is my opinion that it is inappropriate to do nothing. I would hope for acquired or innate natural immunity to kick in when used with other less aggressive but pro-active treatments, such as using biological cleaners, medicated foods, UV, ozone, and garlic. Although I clearly dont believe this shotgun approach of unproven treatments is the most effective option available. For me, if you gamble with un-quarantined items and infect your tank, it is best to bite the bullet, remove all the fishes to a separate quarantine aquarium, fallow the tank, and use a proven treatment.. Treatment Option 6: Freshwater Dips. Freshwater dips are a highly effective form of treatment against a wide variety of parasites, although their use against Cryptocaryon irritans has been questioned (Colorni, 1985). I am including them here because I still choose to employ them, as I believe they have at least some effect against Ich and because they have been proven effective ...

Protozoa-associated methanogens (PAM) are considered one of the most active communities in the rumen methanogenesis. This experiment investigated whether methanogens are sequestrated within rumen protozoa, and structural differences between rumen free-living methanogens and PAM. Rumen protozoa were harvested from totally faunated sheep, and six protozoal fractions (plus free-living microorganisms) were generated by sequential filtration. Holotrich-monofaunated sheep were also used to investigate the holotrich-associated methanogens. Protozoal size determined the number of PAM as big protozoa had 1.7,br,3.3 times more methanogen DNA than smaller protozoa, but also more endosymbiotic bacteria (2.2- to 3.5-fold times). Thus, similar abundance of methanogens with respect to total bacteria were observed across all protozoal fractions and free-living microorganisms, suggesting that methanogens are not accumulated within rumen protozoa in a greater proportion to that observed in the rumen as a whole. ...

Chilodonella cyprini and Ch. hexasticha were described in the first decade of twentieth century. Ch. hexasticha has been reported from Former USSR, Germany, Poland, Czechoslovakia, and the USA (Kiernik 1909; Prost 1952; Kazubski and Migala 1974; Lom et al. 1976; Wierzbicka 1997). However, descriptions of Ch. cyprini and Ch. hexasticha were not precise due to imperfect methods of study used at that time, so the distinctness of both species was questioned, before Kazubski and Migala (1974) described Ch. cyprini and Ch. hexasticha in detail and expounded the differences between them. There are differences between Ch. cyprini and Ch. hex- asticha by Kazubski and Migala: (1) These species differ mainly by the number of kineties, which is larger in Ch. cyprini and smaller in Ch. hexasticha. (2) The differences concern the arrangement of kineties. In Ch. cyprini, the kineties are close one to the other, lying in nearly equal distances, while in Ch. hexasticha the kineties are loosely arranged and the ...

Phytoplankton have adapted to survive in the variable and heterogeneous environment that is characteristic of lakes in temperate regions. One strategy for survival during periods unfavorable for growth is to form resting propagules. Dinoflagellates are bloom-forming phytoplankton which have the ability to form resistant and long-lived resting cysts. The role of cysts in the ecology and life history of dinoflagellates was investigated in this thesis. First, it was tested whether cysts have the ability to assimilate phosphorus (P) during dormancy, which could improve the survival of newly germinated cells when returning to the water column. Secondly, the role of resting cysts in regulating the seasonal succession of dinoflagellates in Lake Erken was examined. Also. biotic and abiotic factorscontrolling the timing of germination were tested.. Cysts of the marine dinoflagellate Scrippsiella trochoidea which were incubated in P enriched medium attained a P content twice that of cysts incubated in P ...

This disinfecting agent contains acridine dye which eliminates parasitic infections such as Costia Sp. or Chilodonella Sp., and infections caused by mould fungi. It also impedes the growth of algae and has an antibacterial effect. As it is born very well by a clear majority of aquarium fish, it is very popular among aquarists.. In small concentrations it is suitable for the treatment of spawn during its growth. We remind professional aquarists that the use of this agent must be well coordinated with the pH of the growth water and with the light intensity (brood tanks are usually shaded in order to reduce it).. It is highly effective at treating skin and bacterial infections, especially if the treated fish can tolerate a substantial (but individual) addition of salt.. It may be used in decorative tanks (for example of the Dutch type), but only in the case of long-term treatment which usually suspends the growth of plants but does not kill them. Plants could be killed in case of intensive ...

Large numbers elicit no obvious host-response and attachment to the gills, mantle cavity or esophageal pouch epithelium appears to be superficial. Some populations of Mantoscyphidia sp. in abalone had attached ectosymbiotic ellobiophryid ciliates with no apparent adverse affects to the host ciliate or abalone (H. midae and H. spadicea) (Botes et al. 1998). Ciliates similar in morphology to Mantoscyphidia sp. were observed in the esophageal pouches of cultured juvenile H. kamtschatkana held in tanks for several months with an inadequate supply of food in British Columbia, Canada. Caceres-Martinez and Tinoco-Orta (2001) suggested that the ciliates in the esophageal pouches of cultured H. rufescens in Baja California may be commensal symbionts because prevalence and total numbers were similar in healthy and moribund abalone but indicated that further studies are required to determine the nature of the symbiosis.. ...
There are mainly three types of skin cancer namely: 1.BASAL-CELL CARINOMA 2.SQUAMOUS-CELL CARCINOMA 3.MELANOMA The malignancies of the skin remain restricted in the epidermis, mostly due to invisible ultraviolet rays emitted by the sun. The ozone gas present in the air absorb most of the suns radiation, so that only a small percentage of ultraviolet radiation of longest wave length (UVA) and ultraviolet radiation of shortest wave length (DYB) reaches the earths surface. The UVB rays are known to burn the skin more easily and have cancer-causing potential. The disease usually occurs as a small, pearly bump on the face, neck, hands or the nose. If left untreated, the basel-cell carcinomas can crust, bleed or ulcerate. These tumors take months or years to grow_ to half an inch in diameter. They root under the skin, causing disfigurement and damage underlying bone, cartilage and muscle. It has a cure rate of better than ninety-nine per cent if detected early.

It is a technology that produces the hydrogen gases by using only the microorganism and sunlight from the wastewater to be at a loss because of processing. And, the produced hydrogen uses the fuel cell and is used to generate electricity. Because this technology doesnt use the organic matter that becomes food, and use the organic matter included in waste, clean power generation is possible. We researched the improvement of the hydrogen gas production efficiency. The purple non-sulfur photosynthesis bacillus was purely cultured, the substrate dependency was clarified, and the best substrate dosage was decided. Moreover, it was shown that the light wave length conversion net was effective for the hydrogen gas production efficiency improvement. On the other hand, a too strong light intensity showed becoming the growth obstruction of phototropic bacteria. When the light intensity for the photosynthesis is insufficient, the light wave length conversion net can support this. On the other hand,
Todays solar cells capture about 15 percent of the suns light. The reason why more is not absorbed is that only visible sun light is captured, says Senior Research Scientist Arne Røyset. The conventional way of thinking is that the solar cells shall adapt themselves to the light. We have chosen to reverse the problem and also work on the sun light adapting itself to the solar cells.. Humans can see light in the spectrum from 400 to 700 nanometres. Ordinary solar cells capture light right up to 1000 nanometres but, in spite of this, much of the light escapes. Sunlight has a specific wave length and quantity of energy. By combining two and two particles, the quantity of energy doubles, while the wave length halves. The thin film is placed on the outside of the solar cells and it is the optical properties that make this possible, says Røyset. By halving the wavelength, invisible light becomes visible and, as a result, it is captured by sun cells. We call this frequency conversion or light ...
This laser ranks up there with the invention of the automobile, the discovery of penicillin and the polio vaccine. It is truly capable of change that seems unbelievable unless you have felt the change or seen the change! There are several reasons we use this specific laser: (1) its power output is only 1/200th of a WATT where in biological terms, the lower the power the greater the benefit; (2) it is one of the only TRUE lasers around with a wave length of 635 nanometers (a nanometer is a billionth of a meter) which has been proven in all of the scientific studies to be the wave length that is most effective and least harmful to the cell, and (3) the massive research and FDA Clearance has demonstrated the safety of this laser in that there has never been a recorded negative side effect of any kind in hundreds of studies. This laser has had a profound effect on the ideas we held about Rolfing. It has totally changed the landscape of this profession because it has now been demonstrated that what ...

Biology of the Cell / Under the Auspices of the European Cell Biology Organization. 2012 Jun 01; 104: 309-25.. External Citation. Abstract. Genomes, like crazy patchwork quilts, are stitched together over evolutionary time from diverse elements, including some unwelcome invaders. To deal with parasitic mobile elements, most eukaryotes employ a genome self-defensive manoeuvre to recognise and silence such elements by homology-dependent interactions with RNA-protein complexes that alter chromatin. Ciliated protozoa employ more offensive tactics by actually unstitching and reassembling their somatic genomes at every sexual generation to eliminate transposons and their remnants, using as patterns the maternal genomes that were rearranged in the previous cycle. Genetic and genomic studies of the distant relatives Paramecium and Tetrahymena have begun to reveal ...

Whole genome sequencing analyses are providing compelling evidence that pro- and eukaryote microbes, like multicellular organisms, have their life threatened by parasitic attacks. Bacteria and Archea face invading viral nucleic acids with an inheritable DNA-encoded immunity (known as the CRISPR-Cas system) that recognizes foreign DNA from self DNA. In eukaryotic microbes that are exposed to invasions from both bacteria and viruses, bacteria are promptly made harmless either by digestion into food vacuoles, or by domestication as symbionts. But the defence from viral attacks is much less effective. Foreign viral sequences can randomly insert into the cell genome, and may disrupt or deactivate vital genes. To fight this threat, ciliates rely on a unique model of inheritable genomic immune mechanism based on the evolution of two genomes, a germ-line one lying in the cell micronucleus and a somatic one lying in the macronucleus. The germ-line genome characterized by an orthodox chromosomic ...
