The photoreduction of H(2)O(2) by Synechococcus sp. PCC 7942 and UTEX 625. (1/32)

It has been claimed that the sole H(2)O(2)-scavenging system in the cyanobacterium Synechococcus sp. PCC 7942 is a cytosolic catalase-peroxidase. We have measured in vivo activity of a light-dependent peroxidase in Synechococcus sp. PCC 7942 and UTEX 625. The addition of small amounts of H(2)O(2) (2.5 microM) to illuminated cells caused photochemical quenching (qP) of chlorophyll fluorescence that was relieved as the H(2)O(2) was consumed. The qP was maximal at about 50 microM H(2)O(2) with a Michaelis constant of about 7 microM. The H(2)O(2)-dependent qP strongly indicates that photoreduction can be involved in H(2)O(2) decomposition. Catalase-peroxidase activity was found to be almost completely inhibited by 10 microM NH(2)OH with no inhibition of the H(2)O(2)-dependent qP, which actually increased, presumably due to the light-dependent reaction now being the only route for H(2)O(2)-decomposition. When (18)O-labeled H(2)O(2) was presented to cells in the light there was an evolution of (16)O(2), indicative of H(2)(16)O oxidation by PS 2 and formation of photoreductant. In the dark (18)O(2) was evolved from added H(2)(18)O(2) as expected for decomposition by the catalase-peroxidase. This evolution was completely blocked by NH(2)OH, whereas the light-dependent evolution of (16)O(2) during H(2)(18)O(2) decomposition was unaffected.  (+info)

The effects of ammonia on pancreatic enzyme secretion in vivo and in vitro. (2/32)

BACKGROUND: Recent studies clearly demonstrate that Helicobacter pylori (H. pylori) infection of the stomach causes persistent elevation of ammonia (NH3) in gastric juice leading to hypergastrinemia and enhanced pancreatic enzyme secretion. METHODS: The aim of this study is to evaluate the influence of NH4OH on plasma gastrin level and exocrine pancreatic secretion in vivo in conscious dogs equipped with chronic pancreatic fistulas and on secretory activity of in vitro isolated acini obtained from the rat pancreas by collagenase digestion. The effects of NH4OH on amylase release from pancreatic acini were compared with those produced by simple alkalization of these acini with NaOH. RESULTS: NH4OH given intraduodenally (i.d.) in increasing concentrations (0.5, 1.0, 2.0, 4.0, or 8.0 mM/L) resulted in an increase of pancreatic protein output, reaching respectively 9%, 10%, 19%, 16% and 17% of caerulein maximum in these animals and in a marked increase in plasma gastrin level. NH4OH (8 x 0 mM/L, i.d.) given during intravenous (i.v.) infusion of secretin (50 pmol/kg-h) and cholecystokinin (50 pmol/kg-h) reduced the HCO3 and protein outputs by 35% and 37% respectively, as compared to control obtained with infusion of secretin plus cholecystokinin alone. When pancreatic secretion was stimulated by ordinary feeding the same amount of NH4OH administered i.d. decreased the HCO3- and protein responses by 78% and 47% respectively, and had no significant effect on postprandial plasma gastrin. In isolated pancreatic acini, increasing concentrations of NH4OH (10(-7)-10(-4) M) produced a concentration-dependent stimulation of amylase release, reaching about 43% of caerulein-induced maximum. When various concentrations of NH4OH were added to submaximal concentration of caerulein (10(-12) M) or urecholine (10(-5) M), the enzyme secretion was reduced at a dose 10(-5) M of NH4OH by 38% or 40%, respectively. Simple alkalization with NaOH of the incubation medium up to pH 8.5 markedly stimulated basal amylase secretion from isolated pancreatic acini, whereas the secretory response of these acini to pancreatic secretagogues was significantly diminished by about 30%. LDH release into the incubation medium was not significantly changed in all tests indicating that NH4OH did not produce any apparent damage of pancreatic acini and this was confirmed by histological examination of these acini. CONCLUSIONS: 1. NH4OH affects basal and stimulated pancreatic secretion. 2. The excessive release of gastrin may be responsible for the stimulation of basal pancreatic enzyme secretion in conscious animals, and 3. The inhibitory effects of NH4OH on stimulated secretion might be mediated, at least in part, by its direct action on the isolated pancreatic acini possibly due to the alkalization of these acini.  (+info)

The oxidation state of the photosystem II manganese cluster influences the structure of manganese stabilizing protein. (3/32)

Exposure of photosystem II membranes to trypsin that has been treated to inhibit chymotrypsin activity produces limited hydrolysis of manganese stabilizing protein. Exposure to chymotrypsin under the same conditions yields substantial digestion of the protein. Further probing of the unusual insensitivity of manganese stabilizing protein to trypsin hydrolysis reveals that increasing the temperature from 4 to 25 degrees C will cause some acceleration in the rate of proteolysis. However, addition of low (100 microM) concentrations of NH2OH, that are sufficient to reduce, but not destroy, the photosystem II Mn cluster, causes a change in PS II-bound manganese stabilizing protein that causes it to be rapidly digested by trypsin. Immunoblot analyses with polyclonal antibodies directed against the N-terminus of the protein, or against the entire sequence show that trypsin cleavage produces two distinct peptide fragments estimated to be in the 17-20 kDa range, consistent with proposals that there are 2 mol of the protein/mol photosystem II. The correlation of trypsin sensitivity with Mn redox state(s) in photosystem II suggest that manganese stabilizing protein may interact either directly with Mn, or alternatively, that the polypeptide is bound to another protein of the photosystem II reaction center that is intimately involved in binding and redox activity of Mn.  (+info)

Efficacy of common laboratory disinfectants on the infectivity of Cryptosporidium parvum oocysts in cell culture. (4/32)

Nine liquid disinfectants were tested for their ability to reduce infectivity of Cryptosporidium parvum oocysts in cell culture. A 4-min exposure to 6% hydrogen peroxide and a 13-min exposure to ammonium hydroxide-amended windshield washer fluid reduced infectivity 1,000-fold. Other disinfectants tested (70% ethanol, 37% methanol, 6% sodium hypochlorite, 70% isopropanol, and three commercial disinfectants) did not reduce the infectivity after a 33-min exposure. The results indicate that hydrogen peroxide and windshield washer fluid or ammonium hydroxide disinfectant may be suitable laboratory disinfectants against C. parvum oocysts.  (+info)

Structural determination of lipid A of the lipopolysaccharide from Pseudomonas reactans. A pathogen of cultivated mushrooms. (5/32)

The chemical structure of lipid A from the lipopolysaccharide of the mushroom-associated bacterium Pseudomonas reactans, a pathogen of cultivated mushroom, was elucidated by compositional analysis and spectroscopic methods (MALDI-TOF and two-dimensional NMR). The sugar backbone was composed of the beta-(1'-->6)-linked d-glucosamine disaccharide 1-phosphate. The lipid A fraction showed remarkable heterogeneity with respect to the fatty acid and phosphate composition. The major species are hexacylated and pentacylated lipid A, bearing the (R)-3-hydroxydodecanoic acid [C12:0 (3OH)] in amide linkage and a (R)-3-hydroxydecanoic [C10:0 (3OH)] in ester linkage while the secondary fatty acids are present as C12:0 and/or C12:0 (2-OH). A nonstoichiometric phosphate substitution at position C-4' of the distal 2-deoxy-2-amino-glucose was detected. Interestingly, the pentacyl lipid A is lacking a primary fatty acid, namely the C10:0 (3-OH) at position C-3'. The potential biological meaning of this peculiar lipid A is also discussed.  (+info)

Identification of the extracellular loop 2 as the point of interaction between the N terminus of the chemokine MIP-1alpha and its CCR1 receptor. (6/32)

Macrophage inflammatory peptide-1alpha (MIP-1alpha)/CC-chemokine receptor ligand 3 is an 8-kDa peptide that induces chemotaxis of various lymphocytes to sites of inflammation through interaction with the G protein-coupled chemokine receptors CCR1 and CCR5. We recently described the preparation of a photoactivatable derivative of MIP-1alpha labeled with a benzophenone group at the extreme N-terminal end, which is a determinant for the agonist character of chemokines. Benzophenone-MIP-1alpha is a full agonist that specifically and covalently labels CCR1 and CCR5 receptors upon irradiation. In the present study, we use enzymatic and chemical cleavage methods on wild-type and mutated CCR1 receptors to show that the N terminus of the chemokine MIP-1alpha interacts in a specific manner with the second extracellular loop of the CCR1 receptor, within a segment comprising amino acids 178 to 194. This is the first report on the direct identification of a contact point between the N terminus of a chemokine and its membrane-bound receptor. The work shows that the part of chemokines that is endowed with agonist properties interacts with extracellular parts of the receptor rather than the transmembrane core of the protein.  (+info)

Ammonium hydroxide hydrolysis: a valuable support in the MALDI-TOF mass spectrometry analysis of Lipid A fatty acid distribution. (7/32)

Lipid A is the lipophilic moiety of lipopolysaccharides (LPSs), the major components of the external membrane of almost all gram-negative bacteria. It is responsible for the toxicity of LPS and has a heterogeneous structure composed of a bis-phosphorylated glucosamine disaccharide backbone that is acylated at the positions 2, 3 of the GlcN I (proximal) and GlcN II (distal) residue with O- and N-linked 3-hydroxy fatty acids (primary substitution). These fatty acids are further acylated by means of their 3-hydroxy groups (secondary substitution). The toxicity of Lipid A is dependent on its primary structure; the number, the length, and the distribution of the fatty acids on the disaccharide backbone strongly influence the endotoxic activity. In this paper a general and easy methodology to obtain secondary fatty acid distribution, which is one of the most difficult issues in the structural determination of Lipid A, is proposed. The method combines ammonium hydroxide hydrolysis and matrix assisted laser desorption ionization (MALDI)-mass spectrometry analysis and has been successfully proven with five different Lipid A species. The procedure exploits the lower stability under mild alkaline conditions of acyl and acyloxyacyl esters with respect to that of the acyl and acyloxyacyl amides. The partially degraded Lipid A species obtained are analyzed by MALDI-MS. The generality of this approach was tested on five Lipid As, namely those arising from Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Pseudomonas reactans, and Burkholderia caryophylli.  (+info)

Decrease in the efficiency of the electron donation to tyrosine Z of photosystem II in an SQDG-deficient mutant of Chlamydomonas. (8/32)

Photosystem (PS) II activity of a sulfoquinovosyl diacylglycerol (SQDG)-deficient mutant (hf-2) of Chlamydomonas was partially decreased compared with that of wild-type. The susceptibility to 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) was also modified in the mutant. Photometric measurements in the isolated thylakoid membranes of hf-2 revealed that the lowered activity in the mutant was derived from a decrease in the efficiency of the electron donation from water to tyrosine Z, not from the efficiency of the electron transport from Q(A) to Q(B). This result was confirmed by the decay kinetics of chlorophyll fluorescence determined in vivo. We conclude that SQDG contributes to maintaining the conformation of PSII complexes, particularly that of D1 polypeptides, which are necessary for maximum activities in Chlamydomonas.  (+info)

This inaccurate notion has been spread by some movies and TV personalities. Ammonia is naturally occurring, found in the human body, beef, other proteins, and virtually all foods. It plays an important role in the bodys nitrogen cycle and in helping the body synthesize the protein. It also maintains the pH level that the body needs.. One form of ammonia - ammonium hydroxide - is used in processing foods like baked goods, cheeses, chocolates and some beef products. This is not the same type of ammonia in household cleaners. It is classified as safe by the U.S. Food and Drug Administration (FDA) and is approved in most other countries, including the European Union. When used for meat processing, ammonium hydroxide creates an environment that is unfriendly to pathogenic bacteria, such as E. coli O157:H7 and provides a significant food safety benefit. ...
Alzheimers disease is the leading cause of dementia in the elderly. Pathologically it is characterized by the presence of amyloid plaques and neuronal loss within the brain tissue of affected individuals. It is now widely hypothesised that fibrillar structures represent an inert structure. Biophysical and toxicity assays attempting to characterize the formation of both the fibrillar and the intermediate oligomeric structures of Aβ typically involves preparing samples which are largely monomeric; the most common method by which this is achieved is to use the fluorinated organic solvent 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Recent evidence has suggested that this method is not 100% effective in producing an aggregate free solution. We show, using dynamic light scattering, size exclusion chromatography and small angle X-ray scattering that this is indeed the case, with HFIP pretreated Aβ peptide solutions displaying an increased proportion of oligomeric and aggregated material and an increased

To fulfil the UN millennium goals for sustainable development, there is an urgent need for alternatives to conventional water based sanitation. Faeces and urine contain valuable plant nutrients and should be considered as resources rather than wastes. Collection with efficient water usage enables faeces and urine to be reused and environmental pollution may be better prevented. When using human excreta as plant fertilisers, it is important to prevent disease transmission by reducing the content of gastrointestinal pathogens. Nitrogen based treatment of faeces and manure with ammonium hydroxide and urea has been shown to be an efficient method for inactivating bacterial pathogens, nematode eggs and protozoan cysts. The substance responsible for microbial inactivation is uncharged ammonia, NH3 (aq). As ammonia is a weak base, the ammonia equilibrium can be controlled by additions of alkaline agents such as lime. A pH above 8 is needed to produce substantial amounts of ammonia in the form of ...

Jacqueline, I dont do as much GMA as I used to so these suggestions may not be the most helpful. I always found that a few drops, number depending upon the size of your water bath, of ammonium hydroxide always helped flatten and expand the sections. I did this using a room temperature water bath. Also I found GMA sections harder to keep flat and properly expanded the thicker they were cut. We routinely cut GMA at 1-2 microns rather then 5.

An automated dispensing device is provided that dispenses a calibrated quantity of a fluid into a receptacle having a plurality of spaced-apart rows of receiving wells. The calibrated quantity of fluid is determined based upon a dispensing time and a dispensing scale factor that accounts for the viscosity of the fluid to be dispensed. The automated dispensing device can be configured with independently controllable nozzles for selective delivery of fluid. The automated dispensing device is particularly suitable for dispensing a calibrated quantity of ammonium hydroxide into the receiving wells of each row of a microtiter plate for oligonucleotide cleavage.

Far-from-equilibrium steady-state basaltic glass dissolution rates were measured using newly developed Bacterial Mixed-Flow Reactors (BMFR) at 25°C. Experiments were performed in aqueous pH 4, 6, 8, and 10 buffer solutions with and without nutrients and in: 1) the absence of bacteria, 2) the presence of 0.1-0.4g wet/L dead Pseudomonas reactans, and 3) in the presence of 0.9-19.0g wet/L live P. reactans extracted from a deep subsurface oxygen-bearing basaltic aquifer. The BMFR allows steady-state rate measurements at constant concentrations of live or dead bacteria. Experiments ran for 30-60days on a single basaltic glass powder, initially at bacteria- and nutrient-free conditions until Si steady-state glass dissolution was achieved. Then, in 2-4 steps, either live or dead P. reactans were added via nutrient-rich or nutrient-free inlet solutions, and the flux of Si and other mineral constituents from the basaltic glass were measured until a new chemical steady state was attained. Scanning ...
Due to its high refractive index of 2.45 and its large Knoop hardness compared to organic photoresists, As2S3 has been investigated for the fabrication of photonic crystals with a full-photonic band-gap. Advances in laser patterning techniques such as three-dimensional direct laser writing (3-D DLW) and chemical wet-etching chemistry, has allowed this material to be used as a photoresist to fabricate 3-D nanostructures.[13][14]. As2S3 has been investigated for use as a high resolution photoreist material since the early 1970s,[15][16] using aqueous etchants. Although these aqueous etchants allowed for low-aspect ratio 2-D structures to be fabricated, they do not allow for the etching of high aspect ratio structures with 3-D periodicity. Certain organic reagents, used in organic solvents, permit the high-etch selectivity required to produce high-aspect ratio structures with 3-D periodicity. ...

This girl hurt Chuck, and Levi shows us that. This double life Chuck leads is awfully lonely, and Levi shows us that, too. He wants a normal life, and Jills return -- even though she winds up entangled in another spy mission -- suggests he can occasionally have something like that. And you realize that as much as Sarah makes his heart skip a beat, Chuck wasnt totally lying in Chuck vs. the Break-Up when he told her hed be better off with a real, down-to-earth girlfriend. And Levi shows us all of that with a very expressive performance that in turn elevates the sillier stuff. Chuck planting one on Casey would be funny regardless, but because we believe in Chuck and therefore believe in this life-or-death situation, its actually funnier to see him talk himself into this ridiculous path. And when Chuck gets his second standing ovation in as many episodes (hes on a good streak right now in spy world, isnt he?), his moment of triumph is all the sweeter ...
Although inflammation and protease/antiprotease imbalance have been postulated to be critical in cigarette smokeCinduced (CS-induced) emphysema, oxidative stress has been suspected to play an important role in chronic obstructive pulmonary diseases. transcription factor which, upon activation in response to oxidative or electrophilic stress, detaches from its cytosolic inhibitor, Keap1, translocates to the nucleus, and binds to the antioxidant response element (ARE) in the promoter of target genes, leading to their transcriptional induction (13). Though little is known about Nrf2-regulated genes in the lungs, the recognized members of this group include several critical antioxidant genes, such as heme oxygenase-1 (HO-1), Cglutamyl cysteine synthase (-GCS), and several members of the glutathione S-transferase (GST) family (13). We have postulated that Nrf2 is a critical transcription factor that determines susceptibility to lung inflammation, oxidative stress, and alveolar cell apoptosis caused ...

Mixing about 1 part HCl (Which can be found at most hardware stores, also known as Muriatic Acid. Ask for concrete cleaner.) into 2 parts Hydrogen peroxide (normally used for cleaning cuts) you can make a fairly powerful etchant. Use gloves and dont breathe the fumes though. This will etch a 3x5 board in less than 10 minutes. No need to heat it up. I usually like to drill a small hole through the board on a corner and thread a wire or nylon string through to help agitate / remove the board. When the board is done etching, the etchant will probably look like green kool-aid, from the copper content in it. This stuff is highly corrosive and will burn skin, which is why you should wear gloves. But it is easy to handle, and fairly easy to dispose of. the etchant is easily deactivated with baking soda. Pour enough baking soda into it slowly (to keep it from boiling and overflowing... remember what happens with baking soda/vinegar? ya...) until it is a solid mass, then leave it in the sun to dry. ...

During application, electrocatalysts are exposed to harsh electrochemical conditions, which can induce degradation. This work addresses the degradation of AuPd bimetallic catalysts used for the electrocatalytic production of hydrogen peroxide (H2O2) by the oxygen reduction reaction (ORR). Potential-dependent changes in the AuPd surface composition occur because the two metals have different dissolution onset potentials, resulting in catalyst dealloying.

Abstract: The geometric structures and stabilities of small ZrmOn (1≤m≤5, 1≤n≤2m) clusters were studied using density functional theory (DFT) calculations with the Perdew-Wang exchange correlation functional and the generalized gradient approximation (GGA). The lowest energy structures of all these clusters were obtained by the sequential oxidation of the small core zirconium clusters. In general, the O atoms prefer the bridge sites along the Zrm skeleton. The ground-state structures of the (ZrO2)3 and (ZrO2)5 clusters are consistent with coordination number rules and bonding regularity. The fragmentation channels and fragmentation energies of the small zirconium oxide clusters were discussed. We found that the ZrmO2m-1 clusters (not including Zr4O7) had the largest fragmentation energy among the clusters with the same number of zirconium atoms.. Key words: Density functional theory, Zirconium oxide cluster, Fragmentation channel, Bonding regularity ...

Novel gas sensors embroidered into fabric substrates based on polymers/ SWNT-COOH nanocomposites were proposed in this paper, aiming for their use as a wearable electronic nose (e-nose). The fabric-based chemical gas sensors were fabricated by two main processes: drop coating and embroidery. Four potential polymers (PVC, cumene-PSMA, PSE and PVP)/functionalized-SWCNT sensing materials were deposited onto interdigitated electrodes previously prepared by embroidering conductive thread on a fabric substrate to make an optimal set of sensors. After preliminary trials of the obtained sensors, it was found that the sensors yielded a electrical resistance in the region of a few kilo-Ohms. The sensors were tested with various volatile compounds such as ammonium hydroxide, ethanol, pyridine, triethylamine, methanol and acetone, which are commonly found in the wastes released from the human body. These sensors were used to detect and discriminate between the body odors of different regions and exist in various

Y1 - 2002/9. N2 - Iron exacerbates various types of liver injury in which nuclear factor (NF)-κB-driven genes are implicated. This study tested a hypothesis that iron directly elicits the signaling required for activation of NF-κB and stimulation of tumor necrosis factor (TNF)-α gene expression in Kupffer cells. Addition of Fe2- but not Fe3+ (∼-5-50 μM) to cultured rat Kupffer cells increased TNF-α. release and TNF-α. promoter activity in a NF-κB-dependent manner. Cu+ but not Cu2+ stimulated TNF-α protein release and promoter activity but with less potency. Fe2+ caused a disappearance of the cytosolic inhibitor κBα, a concomitant increase in nuclear p65 protein, and increased DNA binding of p50/p50 and p65/p50 without affecting activator protein-1 binding. Addition of Fe2- to the cells ...
Background: We and others have reported that myocardial protein phosphatase 1(PP1) activity in the end-stage heart failure (HF) is abnormally increased and contributes to the depressed cardiac function. In this regard, in vivo myocardial PP1 inhibition via endogenous cytosolic inhibitors such as inhibitor-2 (INH-2) has prevented HF progression by augmenting phospholamban (PLN) phosphorylation and thereby increasing cardiac function in the genetic cardiomyopathy model. However, it remained uncertain how INH-2, a cytosolic protein, exerts PP1 inhibition in the sarcoplasmic reticulum (SR). To this end, we investigated the molecular mechanism by which INH-2 inhibits PP1 and regulates contractility in cardiomyocytes.. Methods and Results: Cardiomyocytes were enzymatically isolated from six week-old male Wistar rats (n=10) and subjected to either adenoviral INH-2 infection or chemical PP1 inhibition by an application of 0.01-1microM of tautomycin (TM) and tautomycetin (TMC), followed by assessment of ...
Our study evaluated the effects of low voltage electrical stimulation (ES) during bleeding and hot boning at 1 hr postmortem on loin eye (LE) and top round (TR) muscles. Possibly because of relatively slow initial chilling rate used in our study, hot-boned (HB) muscles, even without ES, were comparable to conventionally chilled and boned counterparts. In fact, coupling ES with HB proved less desirable than HB only ...
No reliable toxicokinetic data (animal or human studies) are currently available on zirconium basic sulfate, which is an insoluble zirconium compound. However, a qualitative toxicokinetics assessment has been performed based on the physicochemical characteristics of the substance and on the available reliable toxicological data presented in this dossier. Generally it is assumed that, for metals and metal compounds, the metal ion (regardless of the counterparts of the metal in the respective metal compounds), is responsible for the observed systemic toxicity. Information on other zirconium compounds can thus be used as long as account is taken of their inherent properties. In addition, as indicated in ECHAs guidance on QSAR and grouping of chemicals (ECHA Chapter R.6, 2008), comparison of the water solubility can be used as a surrogate to assess the bioavailability of metals, metal compounds and other inorganics compounds. This simplistic approach assumes that a specific water soluble ...

Ultra-Etch etchant is a 35% phosphoric acid solution. It features ideal viscosity, which, along with the use of the Blue Micro™ or Inspiral™ Brush tip, facilitates precision placement and superior control. Ultra-Etch etchant is self-limiting in its depth of etch (average depth of 1.9μm with 15-second etch),1 creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch etchants unique self-limiting chemistry creates an optimal surface to receive resin.2 Though Ultra-Etch etchant is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.. ...

... is the silicon analogue of methane. Because of the greater electronegativity of hydrogen in comparison to silicon, this Si-H bond polarity is the opposite of that in the C-H bonds of methane. One consequence of this reversed polarity is the greater tendency of silane to form complexes with transition metals. A second consequence is that silane is pyrophoric - it undergoes spontaneous combustion in air, without the need for external ignition.[11] However, the difficulties in explaining the available (often contradictory) combustion data are ascribed to the fact that silane itself is stable and that the natural formation of larger silanes during production, as well as the sensitivity of combustion to impurities such as moisture and to the catalytic effects of container surfaces causes its pyrophoricity.[12][13] Above 420 °C, silane decomposes into silicon and hydrogen; it can therefore be used in the chemical vapor deposition of silicon. The Si-H bond strength is around 384 kJ/mol, which ...

The RNA world hypothesis is supported by RNA's ability to store, transmit, and duplicate genetic information, as DNA does. RNA can act as a ribozyme, a special type of enzyme. Because it can perform the tasks of both DNA and enzymes, RNA is believed to have once been capable of supporting independent life forms.[15] Some viruses use RNA as their genetic material, rather than DNA.[45] Further, while nucleotides were not found in experiments based on Miller-Urey experiment, their formation in prebiotically plausible conditions was reported in 2009;[22] the purine base known as adenine is merely a pentamer of hydrogen cyanide. Experiments with basic ribozymes, like Bacteriophage Qβ RNA, have shown that simple self-replicating RNA structures can withstand even strong selective pressures (e.g., opposite-chirality chain terminators).[46] Since there were no known chemical pathways for the abiogenic synthesis of nucleotides from pyrimidine nucleobases cytosine and uracil under prebiotic conditions, it ...

HCN (not HNC) was first detected in June 1970 by L. E. Snyder and D. Buhl using the 36-foot radio telescope of the National Radio Astronomy Observatory.[16] The main molecular isotope, H12C14N, was observed via its J = 1→0 transition at 88.6 GHz in six different sources: W3 (OH), Orion A, Sgr A(NH3A), W49, W51, DR 21(OH). A secondary molecular isotope, H13C14N, was observed via its J = 1→0 transition at 86.3 GHz in only two of these sources: Orion A and Sgr A(NH3A). HCN was then later detected extragalactically in 1988 using the IRAM 30-m telescope at the Pico de Veleta in Spain.[17] It was observed via its J = 1→0 transition at 90.7 GHz toward IC 342. A number of detections have been made towards the end of confirming the temperature dependence of the abundance ratio of [HNC]/[HCN]. A strong fit between temperature and the abundance ratio would allow observers to spectroscopically detect the ratio and then extrapolate the temperature of the environment, thus gaining great insight into the ...

A large portion of the soil has been affected by over salinity and it has been known to limit the growth of many plants. Globally, the total area of saline soil was 397,000,000 ha and in continents like Africa, it makes up 2 percent of the soil.[34] The amount of soil salinization has reached 19.5% of the irrigated land and 2.1% of the dry-land agriculture around the world.[35] Soil salinization affects the plants using osmotic potential by net solute accumulation. The osmotic pressure in the plant is what maintains water uptake and cell turgor to help with stomatal function and other cellular mechanisms.[35] Over generations, many plant genes have adapted, allowing plants' phenotypes to change and built different mechanisms to counter salinity effects. The plant hormone ethylene is a combatant for salinity in most plants. Ethylene is known for regulating plant growth and development and adapted to stress conditions. Central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ...
A chemical formula is a way of information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.. The simplest types of chemical formulas are called empirical formulas, which use letters and numbers indicating the numerical proportions of atoms of each type. Molecular formulas indicate the simple ...

Diatomic elements played an important role in the elucidation of the concepts of element, atom, and molecule in the 19th century, because some of the most common elements, such as hydrogen, oxygen, and nitrogen, occur as diatomic molecules. John Dalton's original atomic hypothesis assumed that all elements were monatomic and that the atoms in compounds would normally have the simplest atomic ratios with respect to one another. For example, Dalton assumed water's formula to be HO, giving the atomic weight of oxygen as eight times that of hydrogen[6], instead of the modern value of about 16. As a consequence, confusion existed regarding atomic weights and molecular formulas for about half a century. As early as 1805, Gay-Lussac and von Humboldt showed that water is formed of two volumes of hydrogen and one volume of oxygen, and by 1811 Amedeo Avogadro had arrived at the correct interpretation of water's composition, based on what is now called Avogadro's law and the assumption of diatomic ...
