Motifs in DNA- and RNA-binding proteins whose amino acids are folded into a single structural unit around a zinc atom. In the classic zinc finger, one zinc atom is bound to two cysteines and two histidines. In between the cysteines and histidines are 12 residues which form a DNA binding fingertip. By variations in the composition of the sequences in the fingertip and the number and spacing of tandem repeats of the motif, zinc fingers can form a large number of different sequence specific binding sites.

Mass concentration and elemental composition of PM10 in classrooms. (1/102)

OBJECTIVES: To investigate the sources of high concentrations of particles of < 10 microns diameter (PM10) in classrooms, observed in a previous study on childhood exposure to PM10, and to study the correlation between classroom and outdoor concentrations of mass and elements of PM10. METHODS: Measurements of PM10 were conducted in two schools and outdoors in Amsterdam, the Netherlands. Averaging time was 24 hours for the outdoor measurements and both 8 hours (school time) and 24 hours for the classroom measurements. Analysis by x ray fluorescence was used to measure the elemental composition of 55 samples from the 11 days when measurements were conducted simultaneously in both classrooms and outdoors. RESULTS: For most elements, classroom concentrations were considerably higher than outdoor concentrations, especially during school hours. The highest classroom/outdoor ratios were found for the elements from soils Si, Ca, and Ti. The only measured elements that were not increased were S, Br, Pb, and Cl, which are dominated by non-crustal sources. For S, Br, and Pb, which are generally associated with particles < 1 micron, significant correlations between classroom and outdoor concentrations and between the two classrooms were found. The other elements generally had low correlations. CONCLUSIONS: The results show that the high PM10 concentrations found in our classrooms are probably due to resuspension of coarse particles or suspension of soil material. Due to these excess coarse particles, the correlation between classroom and outdoor concentrations is lower for elements associated with coarse particles than for elements associated with fine particles. As the general composition of PM10 in classrooms differs from the composition of PM10 in ambient air, the high PM10 mass concentrations in classrooms can probably not be directly compared with ambient air quality guidelines.  (+info)

Cytological changes in chlorhexidine-resistant isolates of Pseudomonas stutzeri. (2/102)

Transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy-dispersive analysis of X-ray (EDAX) have been used to examine chlorhexidine diacetate (CHA)-sensitive and -resistant isolates of Pseudomonas stutzeri and to determine the effects of CHA on the cells. Significant differences were observed in the structure, size and elemental composition of CHA-sensitive and -resistant cells. Treatment with CHA produced considerably greater changes in CHA-sensitive cells, with widespread peeling of the outer membrane, a substantial loss of cytoplasmic electron-dense material and extensive lysis. Cells from the resistant isolates showed no blebbing of the outer membrane and no structural damage. X-ray mapping confirmed the difference in CHA uptake between CHA-sensitive and CHA-resistant cells. It is proposed that changes in the outer membrane form a major mechanism of resistance to CHA in P. stutzeri.  (+info)

Characterization of vernix caseosa: water content, morphology, and elemental analysis. (3/102)

Recent studies have prompted interest in the use of epidermal barrier creams as protective biofilms for very low birthweight preterm infants. The key to understanding the role of epidermal barrier films is an elucidation of their interaction with water and a basic knowledge of their composition. In this study, we investigated the morphologic properties and elemental composition of the naturally occurring biofilm, vernix caseosa. This biofilm is typically lacking in preterm infants and its production coincides in utero with terminal differentiation of the epidermis and formation of the stratum corneum. Significantly, vernix (80.5+/-1.0% H2O) had a much higher water content than other barrier creams (Eucerin: 17.1+/-0.6%, Aquaphor: 0.33+/-0.03%, Ilex: 0.19+/-0.02%, petrolatum: 0.03+/-0.01%; all p<0.05). Phase contrast microscopy of vernix showed multiple cellular elements with nucleic "ghosts" embedded in a putative lipid matrix. Transmission electron microscopy revealed flattened structures approximately 1-2 microm in thickness with distinct cellular envelopes indicative of differentiated corneocytes. Compared with mature corneocytes in adult stratum corneum, vernix corneocytes appeared swollen, the density of the keratin filaments was less, and there was a relative lack of tonofilament orientation. Cryofractured specimens were examined by cryoscanning electron microscopy with subsequent elemental localization by X-ray beam analysis. The findings indicate the high water content of vernix is largely compartmentalized within fetal corneocytes. These results are consistent with the novel view of vernix as a "fluid phase" stratum corneum consisting of a hydrophobic lipid matrix with embedded fetal corneocytes possessing unique biomechanical and water-binding properties.  (+info)

Inductively coupled plasma emission spectroscopic and flame photometric analysis of goat epididymal fluid. (4/102)

AIM: The elemental composition of the epididymal luminal fluid (ELF) in adult goat (Capra indica) was investigated. METHODS: ELF was collected by micropuncture from twelve sites along the epididymal duct. The elemental contents was analyzed with inductively coupled plasma (ICP) emission spectroscopy, a microanalytical technique that can simultaneously measure many elements in minute volumes of sample. The Na and K concentrations were determined by flame photometry. RESULTS: ICP spectroscopy showed the presence of copper, calcium, nickel, iron, magnesium, chromium, titanium and zinc in ELF, with fluctuating levels at different sites along the length of the epididymis. Cadmium, cobalt, lead and manganese were not found. The Na+/K+ ratio was seen to be higher at the initial segments of the epididymis and lower at the distal. CONCLUSION: It is proposed that the observed characteristic distribution of elements in ELF may have far reaching implications in sperm maturation and storage known to occur in the epididymis.  (+info)

Natal homing in a marine fish metapopulation. (5/102)

Identifying natal origins of marine fishes is challenging because of difficulties in conducting mark-recapture studies in marine systems. We used natural geochemical signatures in otoliths (ear bones) to determine natal sources in weakfish (Cynoscion regalis), an estuarine-spawning marine fish, in eastern North America. Spawning site fidelity ranged from 60 to 81%, comparable to estimates of natal homing in birds and anadromous fishes. These data were in contrast to genetic analyses of population structure in weakfish. Our findings highlight the need for consideration of spatial processes in fisheries models and have implications for the design of marine reserves in coastal regions.  (+info)

Element concentrations in urine of patients suffering from chronic arsenic poisoning. (6/102)

In order to know the element levels in the urine of patients with chronic arsenic poisoning caused by arsenic assimilated from burning coal via air and food, we investigated various elements in the urine of 16 patients with this disease and 16 controls living in the same county in Guizhou Province of China. Concentrations of 25 elements (Al, As, Ba, Be, Bi, Ca, Cd, Cr, Cu, Fe, Ga, Mg, Mn, Mo, Ni, P, Pb, Rb, Sb, Se, Sn, Sr, Ti, V and Zn) were determined by an inductively coupled plasma mass spectrometer or an inductively coupled plasma atomic emission spectrometer. The average concentrations of Cu, Ga and Sn as well as As in the patients were significantly higher, and those of Cr, Rb, Sr and Ti in the patients were significantly lower than the control values. Al, Ba, Mn, Ni and Se were under detection limit in the patients, though they could be detected in the controls. There were no positive correlations between the concentration of As and the concentrations of other elements, including Cu, Ga and Sn in the patients. The results of this study suggest that As from burning coal might influence the urinary excretion of some elements.  (+info)

Multielement determination and speciation of major-to-trace elements in black tea leaves by ICP-AES and ICP-MS with the aid of size exclusion chromatography. (7/102)

A multielement determination of major-to-trace elements in black tea leaves and their tea infusions was carried out by ICP-AES (inductively coupled plasma atomic emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry). Tea infusions were prepared as usual tea beverage by brewing black tea leaves in boiling water for 5 min. About 40 elements in tea leaves and tea infusions could be determined over the wide concentration range in 8 orders of magnitude. The extraction efficiency of each element was estimated as the ratio of its concentration in tea infusions to that in tea leaves. From the experimental results for the extraction efficiencies, the elements in black tea leaves were classified into three characteristic groups: (i) highly-extractable elements (>55%): Na, K, Co, Ni, Rb, Cs and Tl, (ii) moderately-extractable elements (20-55%): Mg, Al, P, Mn and Zn, and (iii) poorly-extractable elements (<20%): Ca, Fe, Cu, Sr, Y, Zr, Mo, Sn, Ba and lanthanoid elements. Furthermore, speciation of major-to-trace elements in tea infusions was performed by using a combined system of size exclusion chromatography (SEC) and ICP-MS (or ICP-AES). As a result, many diverse elements were found to be present as complexes associated with large organic molecules in tea infusions.  (+info)

Metasomatic origin of quartz-pyroxene rock, Akilia, Greenland, and implications for Earth's earliest life. (8/102)

A quartz-pyroxene rock interpreted as a banded iron formation (BIF) from the island of Akilia, southwest Greenland, contains (13)C-depleted graphite that has been claimed as evidence for the oldest (>3850 million years ago) life on Earth. Field relationships on Akilia document multiple intense deformation events that have resulted in parallel transposition of Early Archean rocks and significant boudinage, the tails of which commonly form the banding in the quartz-pyroxene rock. Geochemical data possess distinct characteristics consistent with an ultramafic igneous, not BIF, protolith for this lithology and the adjacent schists. Later metasomatic silica and iron introduction have merely resulted in a rock that superficially resembles a BIF. An ultramafic igneous origin invalidates claims that the carbon isotopic composition of graphite inclusions represents evidence for life at the time of crystallization.  (+info)

The first analysis on a rock started on Sol 3 with Barnacle Bill. The Alpha Particle X-ray Spectrometer (APXS) was used to determine its composition, the spectrometer taking ten hours to make a full scan of the sample. It found all the elements except hydrogen, which constitutes just 0.1 percent of the rocks or soils mass.. The APXS works by irradiating rocks and soil samples with alpha particles (helium nuclei, which consist of two protons and two neutrons). The results indicated that Barnacle Bill is much like Earths andesites, confirming past volcanic activity. The discovery of andesites shows that some Martian rocks have been remelted and reprocessed. On Earth, Andesite forms when magma sits in pockets of rock while some of the iron and magnesium settle out. Consequently, the final rock contains less iron and magnesiums and more silica. Volcanic rocks are usually classified by comparing the relative amount of alkalis (Na2O and K2O) with the amount of silica (SiO2). Andesite is different ...

This ingenious illustrated periodic table by Keith Enevoldsen shows how the chemical elements are part of daily life and is available in a printed version.
The history of the periodic table reflects over a century of growth in the understanding of chemical properties, and culminates with the publication of the first actual periodic table by Dmitri Mendeleev in 1869. [1] While Mendeleev built upon earlier discoveries by such scientists as Antoine-Laurent de Lavoisier and Stanislao Cannizzaro, the Russian scientist is generally given sole credit for development of the actualperiodic table itself. The table itself is a visual representation of the periodic law which states that certain properties of elements repeat periodically when arranged by atomic number.. The table arranges elements into vertical columns (groups) and horizontal rows (periods) to display these commonalities. ----------------- Elemental ideas from ancient times People have known about some chemical elements like gold, silver and copper from antiquity, as these can all be discovered in nature in native form and are relatively simple to mine with primitive tools.

The collection of atmospheric deposition by technical samplers and validated deposition modelling using chemical transport models is spatially complemented by using mosses as bioindicator: since 1990, the European moss survey has been providing data on element concentrations in moss every 5 years at up to 7300 sampling sites. In the moss specimens, heavy metals (since 1990), nitrogen (since 2005) and persistent organic pollutants (since 2010) were determined. Germany participated in all surveys with the exception of that in 2010. In this study, the spatial structures of element concentrations in moss collected in Germany between 1990 and 2015 were comparatively investigated by using Morans I statistics and Variogram analysis and mapped by use of Kriging interpolation. This is the precondition to spatially join the moss survey data with data collected at other locations within different environmental networks and to validate spatial patterns of atmospheric deposition as derived by technical sampling and
Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds is a book written by Annie Besant, C.W. Leadbeater and Curuppumullage Jinarajadasa, who were all members of the Theosophical Society (based at Adyar, India). Annie was at the time the President of the Society having succeeded Henry Olcott after his death in 1907. The first edition was published in 1908, the second edition in 1919, and a third in 1951. Since the first edition was published in 1908, the book is in the public domain, and available in whole or in excerpts, on many sites on the internet. Occult Chemistry states that the structure of chemical elements can be assessed through clairvoyant observation with the microscopic vision of the third eye. Observations were carried out between 1895 and 1933. The book consists both of coordinated and illustrated descriptions of presumed etheric counterparts of the atoms of the then known chemical elements, and of ...

Emphasizing, the other potential applications of biotechnology, the new NASA/Berkeley study mentions replenishing gases for life support only briefly. As well discuss a little later in connection with rocket fuel, the chemical elements needed, oxygen and nitrogen, are available in and in the vicinity of the places where we might put outposts. Its just that the atoms of these elements are not in a breathable form. Rather theyre combined with atoms of other chemical elements. On Mars, for instance, theres plenty of oxygen, but not a drop is useful either to mix with propellant in rocket engines, or for humans to breath. Thats because Martian oxygen atoms are bound with carbon atoms in molecules of carbon dioxide (CO2). For humans, CO2 is a waste product; instead, we need to breathe molecular oxygen (O2) to support life functions. But, in the presence of light, photosynthetic organisms, such as plants, algae, and certain bacteria take in CO2 and water (H2O) in and release O2. In the process, ...

Standard atomic weights last revised based on the 2005 review published in Pure Appl. Chem. 78(11), 2051-2066, 2006 and Aug 2007 release, and here reported to 5 significant figures. Elements with no reported values in the table above have no stable nuclides (alternative tables might display mean relative atomic masses or mass numbers for an arbitrarily selected unstable nuclide of that chemical element). However, three such elements -Th, Pa, and U- have a characteristic terresterial isotopic composition, and for these an atomic weight is tabulated..

Atomic Number: It is the number of protons found in the nucleus of an atom. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. When an atom is in neutral charge, the atomic number is equals to the number of electrons. Isotope: Atoms of the same element having the
Greetings, and welcome to the third installment of a regular feature on the Radleys blog - the Element of the Month.. To choose our element of the month, we used a random number generator to produce a figure between 1 and 118 - the current number of elements in the periodic table. This month, we drew the number 83, which makes bismuth our third element of the month.. Bismuth - The Key Facts. Bismuth is a chemical element with symbol Bi and atomic number 83. It is one of the few elements whose liquid state has a higher density than its solid state.. Almost twice as abundant as gold in the earths crust, bismuth is a brittle metal, silvery white in colour when it is freshly produced, and often seen with a pink tinge due to surface oxidation once in contact with air. Bismuth crystals are truly stunning, as the varying layers of oxidation disturb the light wavelengths that reflect on its surface, creating a veritable rainbow of colours.. Although rather alien-looking, you may be surprised to know ...
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earths crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).more.

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge - a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac-colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, a common constituent of ...

TY - JOUR. T1 - Influence of nicotine on tissue trace element concentrations and tissue antioxidant defense. AU - Dubick, Michael A.. AU - Keen, Carl L. PY - 1991/11. Y1 - 1991/11. N2 - Both altered trace element metabolism and cigaret smoking have been proposed to be risk factors for cardiovascular disease (CVD). Thus, it is important to identify the mechanisms by which cigaret smoke alters trace element metabolism. In the present study, serum trace element concentrations were measured in 19 smokers and 13 nonsmokers. In parallel studies, data from rats treated with 50 mg of nicotine over a 21-d period tested the hypothesis that nicotine induced altered trace element metabolism observed in smokers. Serum Cu and Zn concentrations were significantly higher in smokers than in nonsmokers. Serum nicotine concentrations in rats were comparable to those observed in heavy smokers, but serum trace element concentrations were not significantly altered by nicotine treatment.

Move over, Roentgenium. Theres a new super-heavy chemical element joining the periodic table.. The yet-to-be-named element 112 has been officially recognized by the tables governing body, the International Union of Pure and Applied Chemistry.. A team of scientists, lead by Sigurd Hofmann at the GSI Helmholtzzentrum für Schwerionenforschung (Centre for Heavy Ion Research) in Darmstadt, Germany are credited with its discovery.. The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table, the scientists said in a statement.. Hofmann and his team first synthesized the element in 1996 by firing charged zinc atoms through a 120 meter-long particle accelerator into a lead target. The zinc and lead nuclei were fused to form the new element.. An elements atomic number indicates the number of protons in the nucleus. Element 112 is the sum of the atomic numbers of the two initial elements, zinc having the atomic number 30 and lead the ...

A team of German scientists has been credited with the discovery of the new super-heavy element 112 more than ten years after intensive laboratory work first yielded a single atom of the novel form of matter.. But before the element can be officially added to the periodic table, Sigurd Hofmann and his team of researchers at the Center for Heavy Ion Research in Darmstadt, Germany have to think of a name for their discovery. Professor Hofmanns pursuit to expand the periodic table first started in 1976. Now, the fusion experiments that he and his colleagues used to create the new element have also uncovered the existence of five additional undiscovered elements with atomic numbers 107-111. Among scientist, these rare atoms are known as super-heavy elements a reference to the large number of protons and neutrons located in the nucleus of the atom where the overwhelming majority of every elements mass is located. To create element 112, Professor Hofmanns group used a 1.2 meter-long particle ...
This one is easy, it is sulfur. Z, the atomic number is the number of protons, positively charged nuclear particles. But Z defines the identity of the element, If Z=1, the element is hydrogen, Z=2, the element is helium, .............Z=16, the element is sulfur. How did I know this? Well, I have access to a Periodic Table which lists all known elements according to atomic number. There should be a Periodic Table beside you now! Which element has a total of 19 protons?

One way to teach the periodic table is to make it into a table-setting exercise; this is perhaps best for children ages 8 to about 10. Make a grid for the periodic table with about half-inch squares, and put it on the wall, ideally over a sheet of ferrous metal. Then, using blank refrigerator magnet material (available at most craft stores), or commercial magnetic elements kits, challenge your students to put the elements in their proper places. This can utilize the color coding and numbers to help them-and its the kind of sorting fun that children (and adults) enjoy.. ...

OBJECTIVE: Our purpose was to quantify 36 inorganic chemical elements in aerosols from disposable electronic cigarettes (ECs) and electronic hookahs (EHs), examine the effect of puffing topography on elements in aerosols, and identify the source of the elements. METHODS: Thirty-six inorganic chemical elements and their concentrations in EC/EH aerosols were determined using inductively coupled plasma optical emission spectroscopy, and their source was identified by analyzing disassembled atomizers using scanning electron microscopy and energy dispersive X-ray spectroscopy. RESULTS: Of 36 elements screened, 35 were detected in EC/EH aerosols, while only 15 were detected in conventional tobacco smoke. Some elements/metals were present in significantly higher concentrations in EC/EH aerosol than in cigarette smoke. Concentrations of particular elements/metals within EC/EH brands were sometimes variable. Aerosols generated at low and high air-flow rates produced the same pattern of elements, although ...

N2 - Plant requires 14 mineral elements for their growth and development. These elements in the soil are taken up by the roots, translocated from the roots to the shoots, and distributed to different organs depending on their demands (Marschner P, Mineral nutrition of higher plants, 3rd edn. Academic, London, 2012). In addition to these essential elements, toxic elements such as Cd and As are also transported from the soils to aboveground parts. All these processes require various transporters (membrane proteins). During the last decades, a number of transporters for uptake, translocation, and distribution of mineral elements have been identified, especially in model plants such as Arabidopsis and rice; however, most transporters remain to be identified. In this chapter, transporters identified so far in rice are described, and the regulation ...

Elements have unique physical and chemical properties. A physical property would include characteristics like color or density, a chemical property would include reactions at the atomic level like its crystal structure or atomic structure. An atom only has a composition made of one substance. A single atom is unstable and usually forms a partnership or bonds with itself or other elements. This is called a molecule, which is the stable form that allows us to observe elements in nature. The individual boxes on the Periodic Table of the Elements, helps describe some of the physical and chemical properties of an individual element. If you look at the Hydrogen box (Key)above, you can find the chemical properties such as Atomic Number, Atomic Weight (or what we will refer to as Atomic Mass), Crystal Structure, and Valence-shell configuration. Density, Boiling Point, and Melting Point define some of its physical properties. ...
In 1921 Bohrs new institute for theoretical physics in Copenhagen was established. The same year he developed his ideas of atomic constitution into a theory of the periodic system, covering the electron configurations of all atoms. This new theory relied on the correspondence principle and the new notion of penetrating orbits, but even more so on empirical facts. One result of the eclectic theory was the prediction that the unknown element of atomic number 72 should be a homologue of zirconium, as confirmed by the discovery of hafnium in 1922. However, although Bohrs theory attracted much interest and was seen as a great progress, it was short-lived. Following ideas by E. Stoner, in 1925 W. Pauli presented a superior explanation of the periodic system that built on a new quantum rule, soon known as the exclusion principle.
