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

I devoted this months (first Sunday) Food Matters column in the San Francisco Chronicle to the current hot-button issue, pink slime.. Q: I keep hearing about pink slime being fed to school kids. How could anyone even think about putting something so disgusting in school lunches?. A: Pink slime is the pejorative term for "lean finely textured beef," a product designed to recover useful bits from carcass trimmings. These are warmed, centrifuged to remove the fat, treated with ammonium hydroxide gas to kill pathogens and compressed into blocks that are frozen for later use.. The final product is pink; therefore, its meat - or so says the meat industry. And from a strictly nutritional standpoint, it is. But from any other standpoint, LFTB creates a dilemma.. For one thing, it solves an enormous problem for meat producers. Only about half the weight of the 34 million cattle slaughtered each year is considered fit for human consumption. The rest has to be burned, buried in landfills or sold cheaply ...

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. Hope these suggestions or those from other Netters will help.

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.

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. ...

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 3"x5" 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. ...

Chuck Hunt [Note: Several names and places may be misspelled] Interview conducted by Jim King Bethel, Alaska March 30, 1999 Jim: Im in Chucks office in Bethel. Chuck has done a lot of looking into the programs of the refuges and how they developed and what programs of the refuge and how his participation in the Yukon Delta Refuge programs developed over the years. Im hoping Chuck will want to talk about all those items. Chuck, give us a little background on yourself. CH: I was born in 1944 just north of Kotlik in a small fish camp during the summer and I was raised in a village called Pastolik for quite some time. Until I was about 8 or 9 years old, I didnt attend any formal schooling. We moved to Chaneliak(??) where the BIA school was located and my first schooling started there when I was 8 and 9 and part of 10. In 1955, I went to a BIA school down in Wrangell Institute for the next four summers and then in the fall of 1959, I went to high school at St. Marys. After graduation from high ...

Youve actually come upon a fundamental limitation of computing in general, and binary real number data representation in particular. Floating point numbers are represented as the sum of positive and negative powers of 2, e.g. 2.125 = 2 + 1/8 = 2^1 + 2^-3 = binary 10.001. However, just like numbers such as 1/7 cant be represented exactly in finite-precision decimal, there are plenty of real numbers within the range of representable values that cant be represented exactly in finite-precision (aka digital) binary. So theres always a danger when comparing floating point numbers that the conversion from a decimal number in your code to the binary number in the CPU will have a rounding error that makes it different than the number to which you are comparing it. For a minimal example of this, try this code: ...
