Nitric oxide-induced S-glutathionylation and inactivation of glyceraldehyde-3-phosphate dehydrogenase. (1/261)

S-Nitrosylation of protein thiol groups by nitric oxide (NO) is a widely recognized protein modification. In this study we show that nitrosonium tetrafluoroborate (BF4NO), a NO+ donor, modified the thiol groups of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) by S-nitrosylation and caused enzyme inhibition. The resultant protein-S-nitrosothiol was found to be unstable and to decompose spontaneously, thereby restoring enzyme activity. In contrast, the NO-releasing compound S-nitrosoglutathione (GSNO) promoted S-glutathionylation of a thiol group of GAPDH both in vitro and under cellular conditions. The GSH-mixed protein disulfide formed led to a permanent enzyme inhibition, but upon dithiothreitol addition a functional active GAPDH was recovered. This S-glutathionylation is specific for GSNO because GSH itself was unable to produce protein-mixed disulfides. During cellular nitrosative stress, the production of intracellular GSNO might channel signaling responses to form protein-mixed disulfide that can regulate intracellular function.  (+info)

Arsenic-related Bowen's disease, palmar keratosis, and skin cancer. (2/261)

Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, Bowen's disease, basal-cell-carcinoma, and squamous-cell carcinoma, there is also an increased risk of some internal malignancies. Arsenic-related diseases are common in areas of the world where the drinking water has a high arsenic content. In this paper, we describe a 35-year-old male patient who had arsenic-related keratosis, squamous-cell carcinoma in the palmar area of his left hand, and Bowen's disease on his left thigh. The patient worked in a borax mine for 15 years, so he was exposed to arsenic in drinking water, airborne arsenic in his workplace, and had direct contact. The patient was treated for 11 months for arsenic-related keratosis until an axillary lymph node metastasis occurred; the lesion was excised and diagnosed to be malignant. Bowen's disease was detected when the patient was being treated for cancer. No other malignancy was found. The patient is still receiving regular follow-up care.  (+info)

Chloride channels of glycine and GABA receptors with blockers: Monte Carlo minimization and structure-activity relationships. (3/261)

GABA and glycine receptors (GlyRs) are pentameric ligand-gated ion channels that respond to the inhibitory neurotransmitters by opening a chloride-selective central pore lined with five M2 segments homologous to those of alpha(1) GlyR/ ARVG(2')LGIT(6')TVLTMTTQSSGSR. The activity of cyanotriphenylborate (CTB) and picrotoxinin (PTX), the best-studied blockers of the Cl(-) pores, depends essentially on the subunit composition of the receptors, in particular, on residues in positions 2' and 6' that form the pore-facing rings R(2') and R(6'). Thus, CTB blocks alpha(1) and alpha(1)/beta, but not alpha(2) GlyRs (Rundstrom, N., V. Schmieden, H. Betz, J. Bormann, and D. Langosch. 1994. Proc. Natl. Acad. Sci. U.S.A. 91:8950-8954). PTX blocks homomeric receptors (alpha(1) GlyR and rat rho(1) GABAR), but weakly antagonizes heteromeric receptors (alpha(1)/beta GlyR and rho(1)/rho(2) GABAR) (Pribilla, I., T. Takagi, D. Langosch, J. Bormann, and H. Betz. 1992. EMBO J. 11:4305-4311; Zhang D., Z. H. Pan, X. Zhang, A. D. Brideau, and S. A. Lipton. 1995. Proc. Natl. Acad. Sci. U.S.A. 92:11756-11760). Using as a template the kinked-helices model of the nicotinic acetylcholine receptor in the open state (Tikhonov, D. B., and B. S. Zhorov. 1998. Biophys. J. 74:242-255), we have built homology models of GlyRs and GABARs and calculated Monte Carlo-minimized energy profiles for the blockers pulled through the pore. The profiles have shallow minima at the wide extracellular half of the pore, a barrier at ring R(6'), and a deep minimum between rings R(6') and R(2') where the blockers interact with five M2s simultaneously. The star-like CTB swings necessarily on its way through ring R(6') and its activity inversely correlates with the barrier at R(6'): Thr(6')s and Ala(2')s in alpha(2) GlyR confine the swinging by increasing the barrier, while Gly(2')s in alpha(1) GlyR and Phe(6')s in beta GlyR shrink the barrier. PTX has an egg-like shape with an isopropenyl group at the elongated end and the rounded end trimmed by ether and carbonyl oxygens. In the optimal binding mode to alpha(1) GlyR and rho(1) GABAR, the rounded end of PTX accepts several H-bonds from Thr(6')s, while the elongated end enters ring R(2'). The lack of H-bond donors on the side chains of Phe(6')s (beta GlyR) and Met(6')s (rho(2) GABAR) deteriorates the binding. The hydrophilic elongated end of picrotin does not fit the hydrophobic ring of Pro(2')s/Ala(2')s in GABARs, but fit a more hydrophilic ring with Gly(2')s in GlyRs. This analysis provides explanations for structure-activity relationships of noncompetitive agonists and predicts a narrow pore of LGICs in agreement with experimental data on the permeation of organic cations.  (+info)

Recognition control of the nucleic acid model through conformational switching of nucleobase induced by borate ester formation of cis-2',3'-diol. (4/261)

A novel nucleic acid model that possessed 5'-amino-5'-deoxyuridine at alpha- and gamma-position of L-glutamic acid through amide linkage using 5'-amino group was synthesized and the conformation and the hybridization properties were studied. The complex of alpha-PRNA with complementary DNA/RNA was more stable than the corresponding natural duplex in the absence of borate. Its recognition ability was however lost when borax was added to the solution.  (+info)

Identification of functional arginine residues in ribonuclease A and lysozyme. (5/261)

A specific color reaction has been developed for the detection of N-7, N-8-(1,2-dihydroxycyclohex-1,2-ylene)-L-arginine-containing peptides. The reaction is based on the fact that hydroxylamine converts the blocking group to cyclohexanedione dioxime, which forms a red nickel complex. N-7, N-8-(1,2-dihydroxycyclohex-1,2-ylene)-L-arginine-containing peptides can also be detected by diagonal electrophoresis from the change of electrophoretic mobility of these peptides on interaction of the blocking group with borate. Since the modified arginine residues are resistant to tryptic cleavate, changes in tryptic peptide patterns can also be utilized to identify the presence of modified arginine residues. A combination of these approaches was used to identify the arginine residues modified by cyclohexanedione treatment. Bovine panctreatic RNase A loses approximately 90% of its activity on cyclohexanedione treatment with the modification of 2 to 3 arginine residues. Arginine-39 reacts most rapidly and its modification contributes most to inactivation of the enzyme. Arginine-85 also reacts rapidly with cyclohexanedione. Arginine-10 reacts slowly and no reaction was observed with arginine-33. Removal of the blocking groups by hydroxylamine treatment resulted in complete recovery of enzyme activity in samples where arginine-39 and arginine-85 had been modified, whereas 80% of activity was regained from samples where arginine-10 had also been modified. With egg white lysozyme, all 11 arginine residues react with cyclohexanedione, resulting in partial inactivation of the enzyme. The fully modified enzyme retains 35% of its activity. Since arginine residues are important for electrostatic interaction between the enzyme and the negatively charges cell surface, even the modified, basic residues can provide the necessary positive charges. In the presence of borate, activity is almost completely abolished, since the modified arginine-borate complex has a reduced net positive charge. Upon removal of the blocking groups by hydroxylamine, even the fully modified lysozyme regains complete activity. With the exception of the most reactive arginine (residue 5), modification of all other arginine residues contributes equally to inactivation of the enzyme. The possible reason for the importance of arginine-5 in maintaining activity is discussed. Advantages of the present method for the selective reversible modification of arginine residues of proteins and for the identification of reactive arginine residues are evaluated.  (+info)

The amino acid profiles of the whole plant and of four plant residues from temperate and tropical forages. (6/261)

This study compared the amino acid (AA) profile of five residues (original forage, borate-phosphate buffer residue (BPR), neutral detergent fiber residue with (NDF+) and without (NDF-) sodium sulfite, and acid detergent fiber residue (ADF). Fourteen grasses and legumes from tropical and temperate regions were used in this study. The use of sodium sulfite did not affect the NDF concentration, but the NDF insoluble protein was lower (P < 0.05) in the NDF+ than in the NDF- (3.9 vs 4.5% DM, respectively). For all of the amino acids tested, the amino acid content, expressed as a percentage of CP, was lower in the ADF residue than in the original forage. There were no differences in the amino acid concentrations of the NDF- and NDF+ extracts (P > 0.05). Only in the case of methionine was there a difference in the amount of amino acid when the original forage was compared with the BPR (1.84 vs 1.45 % CP). When the AA profile of each residue was corrected for the AA content of the ADF, no difference was observed between the AA profile of the original forage and of the BPR (P > 0.05). Similar to the result without correction for the amino acids in ADF, the AA profiles of the NDF+ and NDF- fractions were similar (P > 0.05). From this result, we infer that the sodium sulfite had similar effects on all AA in the NDF residue that we tested. There were differences in amino acid concentrations in the original forage and the NDF residues for several amino acids (Met, Cys, Lys, Thr, Arg, Ile, Leu, and Phe) (P < 0.05). When the amino acid values of the original forage and the BPR were used with animal data in the Cornell Net Carbohydrate and Protein System model, few differences in animal predicted performance were evident. These findings suggest that the AA profile of the original forage can be used to predict the AA profile of the undegraded intake protein instead of using the borate-phosphate buffer residue for amino acid analyses. This would simplify obtaining feed amino acid values for use in the Cornell Net Carbohydrate and Protein System.  (+info)

Brief exposure to low-pH stress causes irreversible damage to the growing root in Arabidopsis thaliana: pectin-Ca interaction may play an important role in proton rhizotoxicity. (7/261)

The viability of Arabidopsis thaliana (strain Landsberg) roots exposed to a low pH (4.5 or 4.7) solution that contained 100 microM CaCl(2) was examined by staining with fluorescein diacetate-propidium iodide. The elongation zone of growing roots lost viability within 1-2 h following exposure to low pH, but non-growing roots showed no damage under the same treatment. Low-pH damage in growing roots was irreversible after 1 h incubation at pH 4.5 as judged by regrowth in growing medium at pH 5.6. Growing lateral roots also lost viability in the same treatment, whereas non-growing lateral roots remained viable during and after the treatment. The low-pH damage was ameliorated by the simultaneous application of calcium, indicating the involvement of a calcium-requiring process in overcoming proton toxicity. At pH 5.0, growing roots required 25 microM of calcium to maintain elongation, and at pH 4.8 and pH 4.5 more than 250 microM and 750 microM, respectively. The low-pH damage was ameliorated by divalent cations in the order of Ba2+, approximately Sr2+>/=Ca2+>Mg2+. The monovalent cation K+ showed no ameliorative effect, but borate showed a strong ameliorative effect with Ca2+. These results indicate that the primary target of proton toxicity may be linked to a disturbance of the stability in the pectic polysaccharide network, where calcium plays a key role in plant roots.  (+info)

Inflammatory response, growth, and thyroid hormone concentrations are affected by long-term boron supplementation in gilts. (8/261)

An experiment was conducted to determine the long-term effects of dietary boron (B) on growth performance, immune function, and plasma and serum characteristics in gilts. Fifty weanling gilts were allotted to 10 pens based on weaning weight and litter origin. Pens were randomly assigned to receive one of two dietary treatments. Treatments consisted of a basal diet low in B (control) and the basal diet supplemented with 5 mg B/kg diet as sodium borate. Gilts remained on their respective experimental diets and with their penmates throughout the nursery, growing, and finishing phases. The B concentration of the basal diet was 0.98, 2.1, and 2.2 mg/kg diet during the nursery, growing, and finishing phases, respectively. At the end of each production phase, animals were weighed and feed consumption was determined to assess growth performance variables. In addition, blood samples were obtained from three randomly selected gilts per pen at the completion of each phase. Boron had no affect (P > 0.58) on growth performance during the nursery phase, but gilts receiving supplemental B had increased (P < 0.05) ADG at the end of the finishing phase and over the entire growing-finishing period. Serum concentrations of triiodothyronine (T3) tended (P < 0.07) to be reduced by dietary B at the end of the nursery phase, but serum thyroxine (T4) was not affected (P = 0.46) by B. At the completion of the growing phase, supplemental B decreased (P < 0.05) the concentrations of T3 and T4 in the serum. In addition, serum concentrations of total cholesterol and the activity of alkaline phosphatase were increased (P < 0.05) by dietary B at the end of the growing phase. Serum concentrations of urea N tended (P < 0.09) to be increased by B at the end of the growing phase. Beginning at d 95 of the experimental period, measures of immune function were assessed in randomly selected gilts. Boron decreased (P < 0.05) the inflammatory response to an intradermal injection of phytohemagglutinin. Boron did not affect (P > 0.30) the blastogenic response of isolated lymphocytes to mitogen stimulation or the humoral immune response against a sheep red blood cell suspension. Results indicate that B may affect serum thyroid hormone concentrations, the inflammatory response, and growth in pigs.  (+info)

Treat all of houses wood with a sodium borate Yes, all of the wood should be treated with a sodium borate. What they recommended is fine if all you get is subterranean termites, but there are drywood termites in the area, as well as several species of wood-destroying beetles. Most companies just treat the bottom few feet because all they need is a hand sprayer for that. There are companies that have the necessary equipment to treat all the wood in the house. Either of these will protect the wood for many years from being attacked by any wood-destroying insects, including termites, wood-boring beetles, carpenter ants and carpenter bees. In New Zealand, it has been required since 1954 that all wood used in homes be treated with a sodium borate before installation. Is there an easier and safer way of dealing with these destructive pests? Have your home treated with XT-2000 Orange Oil. With XT-2000, they will use the same amount of product for the beetles, so the cost will be considerably less and
The synthesis of enantioenriched, air-stable secondary alkylmetallic reagents has gained much attention over the past few years; however, competition between product-forming reductive elimination and β-hydride elimination has hindered their efficient cross-coupling. The paradigm of employing a hemilabile ligand to favor reductive elimination has been extended to include an array of amides and benzylic ethers. The synthesis of protected secondary benzylic alcohols through a cross-coupling reaction was explored. Potassium 1-(benzyloxy)alkyltrifluoroborates, synthesized through a diboration of aldehydes, serve as nucleophilic partners in a stereospecific Suzuki-Miyaura reaction, where the benzyl group serves as a stabilizing group to prevent β-hydride elimination. ^ An improved synthesis of potassium β-trifluoroboratoamides utilizing tetrahydroxydiboron and tetrakis(dimethylamino)diboron as greener, more atom-economical dibora sources was explored. Enantioenriched potassium β-trifluoroboratoamides were

AU - Shcheynikov, Nikolay. AU - Zeng, Weizong. AU - Muallem, Shmuel. PY - 2004/11/5. Y1 - 2004/11/5. N2 - Boron is a vital micronutrient in plants and may be essential for animal growth and development. Whereas the role of boron in the life cycle of plants is well documented, nothing is known about boron homeostasis and function in animal cells. NaBC1, the mammalian homolog of AtBor1, is a borate transporter. In the absence of borate, NaBC1 conducts Na+ and OH- (H+), while in the presence of borate, NaBC1 functions as an electrogenic, voltage-regulated, Na+-coupled B(OH)4 - transporter. At low concentrations, borate activated the MAPK pathway to stimulate cell growth and proliferation, and at high concentrations, it was toxic. Accordingly, overexpression of NaBC1 shifted both effects of borate to the left, ...
What Is Borax? Borax (also known as sodium borate decahydrate; sodium pyroborate; birax; sodium tetraborate decahydrate; sodium biborate) is a natural mineral compound (Na2B4O7 • 10H2O). It was discovered over 4000 years ago. Borax is usually found deep within the ground, although it has been mined near the surface in Death Valley, California since the 1800s. Although it has numerous industrial uses, in the home borax is used as a natural laundry booster, multipurpose cleaner, fungicide, preservative, insecticide, herbicide, disinfectant, dessicant, and ingredient in making slime. Borax crystals are odorless, whitish (can have various color impurities), and alkaline. Borax is not flammable and is not reactive. It can be mixed with most other cleaning agents, including chlorine bleach. How Does Borax Clean? Borax has many chemical properties that contribute to its cleaning power. Borax and other borates clean and bleach by converting some water molecules to hydrogen peroxide (H2O2). T. ...
Sodium borate is used in biochemical and chemical laboratories to make buffer solutions, e.g. for gel electrophoresis of DNA. It has a lower conductivity, produces sharper bands, and can be run at higher speeds than can gels made from TBE Buffer or TAE Buffer (five to 35 V/cm as compared to five to ten V/cm). At a given voltage, the heat generation and thus the gel temperature is much lower than with TBE or TAE buffers, therefore the voltage can be increased to speed up electrophoresis so that a gel run takes only a fraction of the usual time. Downstream applications, such as isolation of DNA from a gel slice or Southern blot analysis, work as expected with sodium borate gels. Borate buffers (usually at pH 8) are also used as preferential equilibration solution in DMP-based crosslinking reactions.. Lithium borate is similar to sodium borate and has all of its advantages, but permits use of even higher voltages due to the lower conductivity of lithium ions as compared to sodium ions.[3] However, ...

Traditional methods for the preparation of secondary alkyl-substituted aryl and heteroaryl chlorides challenge both selectivity and functional group tolerance. This contribution describes the use of statistical design of experiments to develop an effective procedure for the preparation of isopropyl-substituted (hetero)arenes with minimal isopropyl to n-propyl isomerization. The reaction tolerates electronically diverse aryl chloride coupling partners, with excellent conversion observed for strongly electron-deficient aromatic rings, such as esters and amides. Electron-rich systems, including methyl- and methoxy-substituted aryl chlorides, were found to be less reactive. Furthermore, the reaction was found to be most successful when heteroaryl chlorides were submitted to the cross-coupling protocol. By mapping substituent effects on reaction selectivity, we were able to show that electron-deficient aryl chlorides are essential for efficient coupling, and use electronic structure calculations to ...

For example white glue molecules are long to begin with, and they are tangled, which is why the glue is so viscous. Once the Borax links up some of the molecules, it becomes even more viscous with a slimy feel. ...
Borax (also known as sodium borate) is a naturallyoccurring mineral found in soil, plants, and even our own bodies.When I was growing up, my mom used it as a laundry booster, which is what most people use it for. In my twenties, I learned to use it as an ingredient in homemade laundry detergent.Then in my thirties, I was surprised to discover over 30 other things you can do with borax!. ...

Although boric acid is known to complex with various polyalcohols, it is often used as a component of buffer mixtures. Electrochemical and spectrophotometric experiments have shown that borate buffers exhibit two types of interference with ortho quinone redox systems. Ortho quinones themselves exist in equilibrium with electroinactive complexes in borate solutions. The corresponding hydroquinones formed by reduction of the quinones complex even more strongly giving complexes which may be oxidized back to the quinone, but at a much higher potential than for the hydroquinone.. ...

Although it cited inconclusive data, a re-evaluation in 2006 by the EPA still found that There were no signs of toxicity observed during the study and no evidence of cytotoxicity to the target organ.[37] In the reevaluation, a study of toxicity due to overexposure was checked and the findings were that The residential handler inhalation risks due to boric acid and its sodium salts as active ingredients are not a risk concern and do not exceed the level of concern... but that there could be some risk of irritation to children inhaling it if used as a powder for cleaning rugs.. Sodium tetraborate decahydrate has no known hazard issues.[38][clarification needed]. Conditions defined as over-exposure to borax dust can cause respiratory irritation, while no skin irritation is known to exist due to borax.

This thesis centers on reactivity of nitric oxide and several of its congeners such as nitroxyl (HNO), nitrite (NO2-), nitrous oxide (N2O) and nitrogen dioxide (NO2) with biomimetic models of copper and zinc enzymes. In addition, metal-free frustrated Lewis pairs are used to capture and activate NO. Tris(pyrazolyl)borate complexes of copper were employed to examine the coordination and NO reactivity of nitrosobenzene (PhNO), an HNO analogue stable towards irreversible dimerization, that provides insight into how HNO can bind to biologically relevant copper enzymes. Tris(pyrazolyl)borate complexes of zinc were used to model the reactivity of zinc bound nitrite (NO2-) with thiols RS-H that generates S-nitrosothiols RSNO that decompose to NO, outlining a new pathway for NO production from NO2-. Reaction of NO with two coordinate -diketiminato copper complexes was consistent with the production of oxidizing cis-hyponitrite intermediates subject to N2O loss to form copper-oxo species. These ...
69. Just what search in Ryker were appellants forced to make, such that their finding was out-of-the-way, and therefore patentable? Certainly they did not have to search through the 52 aryl alkyl ureas for a particular urea. The search was done for them since the particular 1,3 substituted urea they used was commercially available as the herbicide CMU or Telvar (used in the affidavit), a product sold by du Pont, Rykers assignee. Appellants acknowledge that, but the thrust of their argument is that sodium borates is buried in a list of 18 classes of compounds, and that borax is even more buried within the class. But, since the class alkali metal borates is claimed, we need look only for any member of the class, not the particular member borax. The list of the 18 classes is set out on page 8 of the opinion. It is actually two lists, the asterisks separating the first list of hormonal type herbicidal compounds from the remaining list of 14 contact type herbicidal compounds. We are ...
TY - JOUR. T1 - A Nuclear Magnetic Resonance Study of Hydrogen Bonding in Tris(2-N-methylaminoethyl) Borate and Similar Compounds. AU - Meek, Devon W.. AU - Springer, Charles S.. PY - 1966/3. Y1 - 1966/3. N2 - Tris(2-aminoethyl) borate, B(OCH2CH2NH2)3, and the analogous N-methylamino and N,N-dimethylamino compounds have been prepared by the transesterification of methyl borate with the appropriate 2-aminoethanol. The nuclear magnetic resonance spectra show that extensive association of the terminal amino groups occurs in pure tris(N-methylaminoethyl) borate and that this association can be broken apart by heating to 160° or by dissolution in polar organic solvents such as triethylamine or acetonitrile. In order to determine whether the association results from hydrogen bonding or internal B-N coordination, several model systems have been investigated. The spectra of NH2C5H5-BF3, piperidine-BF3, and (C6H5)BO-CH2CH2NH2 in acetonitrile contain very complicated NCH2 peaks and broad NH peaks which ...
In this study, nano sized zinc borate powder with a formula of 4ZnO center dot B2O3 center dot H2O was synthesized using 2ZnO center dot 3B(2)O(3)center dot 3.0-3.5H(2)O as a starting chemical which was produced using a wet chemical method. After dissolving 2ZnO center dot 3B(2)O(3)center dot 3.0-3.5H(2)O in an ammonia solution, the clear solution was boiled until a white powder formed. The resultant powder was characterized with XRD, FTIR, TGA and TEM. XRD, FTIR and TGA results proved that the powder was belonged to the 4ZnO center dot B2O3 center dot H2O. Nano composites of 4ZnO center dot B2O3 center dot H2O-polyvinylchloride (PVC) were produced by injection moulding by adding 1 and 5 wt% zinc borate powders into PVC to enhance its flame retardancy. Limiting oxygen index (LOI) of virgin PVC increased from 41% to 47% and 54% for the 1 and 5 wt% zinc borate added PVC, respectively. Nano zinc borate addition into the PVC does not have considerable negative effect on the mechanical properties of ...

Ulexite, like other borates, is a structurally complex mineral. The basic structure of ulexite contains chains of sodium, water and hydroxide octahedrons linked in endless chains. The chains are linked together by calcium, water, hydroxide and oxygen polyhedra and massive boron units. The basic boron unit has a formula of B5O6(OH)6 and a charge of negative three (-3). It is composed of three borate tetrahedrons and two borate triangular groups. Ulexite is found with the mineral borax and is directly deposited in arid regions from the evaporation of water in intermittent lakes called playas. The playas form only during rainy seasons due to runoff from nearby mountains. The runoff is rich in the element boron and is highly concentrated by evaporation in the arid climate. Eventually the concentration is so great that crystals of ulexite, borax and other boron minerals form and accumulate to great thickness. Specimens of ulexite may form a cotton ball tuft of acicular crystals. These can be ...

Just as anyone who is looking closely at the cleaning products they use around the home is getting used to the name Borax, the EU makes some law that means it will no longer be available on the high street from June. Cleaning gurus often tell us to add borax to our arsenal of natural and traditional cleaning products, along with bicarbonate of soda, white vinegar, lemon juice and soda crystals. A reclassification of the Borates group of minerals means that they are no longer available as a general cleaner. Borax is principally used for cleaning and laundry purposes, but many have also used them to kill ants and weeds for example. Yet all is not lost as Dri-Pak, one of the few suppliers of domestic borax is already supplying a Borax substitute that has all the same cleaning and laundry properties without the potentially hazardous applications ...

Borer infested timber can be treated. The only long-term treatment for borer, is a residual surface application of an insecticide or preservative product, that will last longer than the lifecycle of the borer.. NZ Pest Control, uses MycroBor and Pest-Bor, for all bare timber applications. MycroBor and Pest-Bor, is a water soluable borate powder, that diffuses into the wood and acts as a wood insecticide, fungicide and preservative. These products wont break down over time like most organic compounds, therefore offering longer lasting protection. They are a natural insecticide and fungicide that is widely used as a wood preservative and protectant. Composed of nearly pure sodium borate, a mined crystalline form of boron, these products are virtually odorless and have no known pest resistance. When applied, this type of treatment kills the borer insect, as they emerge towards the timber surface, preventing re-infestation for at least ten years or more, under normal conditions.. On painted and ...
CIR Safety Review: Investigators have reported that Sodium Borate and Boric Acid are poorly absorbed through intact skin. Both compounds are absorbed through abraded, denuded or burned skin. In a 90-day dermal toxicity study, Boric Acid (25-200 mg/kg/day) was nonirritating and nontoxic when applied to intact skin. Sodium Borate and Boric Acid were relatively nontoxic when tested orally. A 5% Sodium Borate water solution was mildly or moderately irritating to the skin, and practically nonirritating when instilled in the eyes. Acute studies indicated that, at 10% in water, Boric Acid was mildly or moderately irritating to the skin. Sodium Borate or Boric Acid in the diet caused growth retardation. Dose levels of Boric Acid much higher than in personal care products caused reproductive effects. Boric Acid was nonmutagenic in a bacterial test system.. Boric Acid induced genetic effects in fruit flies. Limited carcinogenic and developmental toxicity studies did not indicate any effects. In clinical ...
Though generally considered safe, there are some concerns with Borax. The first is that it is an irritant, and can hurt your skin and eyes. This is especially true with young children, who may transfer it from their hands to their mouths if they find it nearby, so you want to keep it out of reach.. Some of the other concerns, however, are a little difficult to root out, because many of the studies that show the ingredient to be toxic arent looking at borax-theyre looking at boric acid, which is slightly different. According to Sutton, men working in boric acid-producing factories have a greater risk of decreased sperm count and libido. But they were exposed to high amounts of boric acid-not small amounts of borax.. The Environmental Protection Agency states that boric acid and borate salts have low toxicity by the oral and dermal (skin) route. Higher doses, however, have been linked with seizures and convulsions, and infants have been accidentally poisoned by boric acid or borax. Neither has a ...
One palladium dichloride adduct of a phosphine-pyridine ligand N-diphenylphosphanyl-2-aminopyridine (L1) [(L1)PdCl2] (1) has been prepared and structurally characterized. Compound 1 can be used as an effective catalyst for the Suzuki-Miyaura cross-coupling reactions of unreactive aryl chlorides with aryl boronic acids, and worked much better than its mono- or bidentate phosphine ligands. The reactions with a wide scope of substrates proceeded to give desired products in good to excellent yields.

Acceptable well documented publication which meets basic scientific principles Read-across is justified on the following basis: The family of zinc borates that include Zinc Borate 500, Zinc Borate 2335 and Zinc Borate 415 (also known as Zinc Borate 411). Zinc borate 500 is anhydrous Zinc Borate 2335 and Zinc Borate 415 has different zinc to boron ratio. Zinc borate 2335 (in common with other zinc borates such as Zinc borate 415 and 500) breaks down to Zinc Hydroxide (via Zinc oxide) and Boric Acid, therefore the family of zinc borates shares the same toxicological properties. Zinc borates are sparingly soluble salts. Hydrolysis under high dilution conditions leads to zinc hydroxide via zinc oxide and boric acid formation. Zinc hydroxide and zinc oxide solubility is low under neutral and basic conditions. This leads to a situation where zinc borate hydrolyses to zinc hydroxide, zinc oxide and boric acid at neutral pH quicker than it solubilises. Therefore, it can be assumed that at physiological ...
Abstract:. td{border:1px solid #ccc;}br{mso-data-placement:same-cell;}. The concentration of boron, an essential micronutrient for plants, presents a narrow range between deficiency and toxicity. In order to provide the boron requirement for plants, and to avoid toxicity problems, boron compounds are mixed with basic fertilizers. Sodium borate pentahydrate was used as a boron source. Ammonium orthophosphates fertilizers with boron were prepared by neutralizing phosphoric acid with ammonia and addition of variable amounts of sodium tetraborate pentahydrate to the reaction mixture at a NH3:H3PO4 molar ratio of 1.5. The fertilizers obtained with boron contents ranging from 0.05 to 1 % (w/w) were fully characterized by chemical analysis, thermal analysis, X-ray diffraction and infrared spectrophotometry. The studies showed that up to 500 °C, regardless of the boron content, no significant changes concerning thermal stability and nutritional properties occurred. Above 500 °C, an increase of thermal ...

Worker-DNELacute, inhalation, local Local effects of borates on the respiratory system have been investigated in animals in four acute inhalation studies (Wnorowski, 1994a, b, 1997) and two Alarie-tests (Krystofiak & Schaper, 1996; Kirkpatrick, 2010). Further, studies in humans were conducted, two small studies under laboratory conditions (Cain et al., 2004, 2008) and three studies on exposed workers (Garabrant et al., 1984, 1985, Wegman et al., 1991). In a study by Woskie et al. (1998) the methods used by Wegman et al. (1991) was evaluated and determinants of human susceptibility to the irritant effect of sodium borates were examined. Boric acid exposure was only studied by Garabrant 1984 and Cain et al. 2008. The Garabrant 1984 study did not distinguish which of the two exposures (boric oxide or boric acid) was associated with reported symptoms. Boric oxide reacts exothermically with water to form boric acid suggesting a possible mechanism for boric oxide irritancy. It is believed that these ...

Boric acid is a weak mineral acid that is a water soluble solid at room temperature. It occurs in nature as a mineral sassolite in volcanic fumaroles and hot springs [1]. It crystallizes in triclinic crystal system. Boric acid is also present in seawater [2]. Borate ions present in seawater contribute in absorbtion of low-frequency sound waves. Pressure exerted from low-frequency soundwaves passing the sea water cause borate ions [B(OH)4]- to lose an -OH group and convert them into molecules of boric acid [B(OH)3]. In the process, the molecules absorb energy from passing sound waves [3]. The compound is prepared upon treatment of borax (Na2B4O7·10H2O) with hydrochloric acid. It acts both as a Lewis acid forming [B(OH)4]- anion and as a weak Bronsted acid with pKa ranging from 9.24 (pKa1) to 13.30 (pKa3).. Na2B4O7·10H2O + 2 HCl →4 B(OH)3 + 2 NaCl + 5 H2O. Boric acid forms many monomeric esters that are readily hydrolyzed in water. A reaction of formation is shifted to the right by using an ...
Flavonoids are bioactive compounds found in plants. Studies indicate consumption of food containing these compounds may reduce the incidences of cancer and cardiovascular diseases. In broccoli, the flavonoids are present at variable concentrations and so far have mainly been determined using high performance liquid chromatography (HPLC). This paper describes a rapid capillary electrophoresis method, involving large volume sample stacking (LVSS), suitable for the analysis of flavonoids in broccoli. Following acid hydrolysis, the two key flavonoids (kaempferol and quercetin) in a broccoli extract were concentrated on-line by LVSS prior to separation by capillary zone electrophoresis (CZE). Using an optimised method, the extract was injected for 50 s into a 50 μm (internal diameter) × 85 cm (total length) capillary followed by stacking/matrix removal at -5 kV for 83 s. The two analytes were then separated in less than 8 min by CZE using a 10 mM sodium borate buffer (pH 8.40) and a separation voltage of

A cross-linking system using boron alpha-hydroxy carboxylic acid salts is shown for use in a water based well treating fluid. The cross-linker will gel the water based fluid usually after a delay at a relatively neutral pH. The cross-linker is provided as a concentrated stable solution containing borate ion as boric acid in a concentration of from less than 1% up to 25% by weight. The cross-linking solution additionally may contain from 1% to 10% of EDTA and/or Glycerine, however, without these additives the cross-linking solution is stable through temperature changes and freeze-and-thaw cycles. Water based fracturing fluid is shown using galactomannan guar polymers, hydroxypropyl guar polymers or derivatives thereof.
Gaudefroyite Ca4Mn3+3-x (BO3)3(CO3)(O,OH) is an unusual mineral containing both borate and carbonate groups and is found in the oxidation zones of manganese minerals, and it is black in color. Vibrational spectroscopy has been used to explore the molecular structure of gaudefroyite. Gaudefroyite crystals are short dipyramidal or prismatic with prominent pyramidal terminations, to 5 cm. Two very sharp Raman bands at 927 and 1076 cm-1 are assigned to trigonal borate and carbonate respectively. Broad Raman bands at 1194, 1219 and 1281 cm-1 are attributed to BOH in-plane bending modes. Raman bands at 649 and 670 cm-1 are assigned to the bending modes of trigonal and tetrahedral boron. Infrared spectroscopy supports these band assignments. Raman bands in the OH stretching region are of a low intensity. The combination of Raman and infrared spectroscopy enables the assessment of the molecular structure of gaudefroyite to be made.. ...
INTRODUCTION. Boron is a chemical element with atomic number 5 and symbol B in periodic table and essential for life. The most common sources of the boron on earth crust are Turkey, United States, Argentina, Chile, Russia, China and Peru (Chong et al., 2000). Boron generally exists in rocks, coal, soil and seawater (Samman et al., 1998) and is released into the atmosphere by forest fires, coal combustion, volcanoes and commercial uses (Howe, 1998). It is commercially used for the manufacture of glass, detergent, ceramic and fertilizer (Argust, 1998). Dehydrated borax and borax pentahydrate are used for fertilizers in plants, surface waters and ground waters (Goldbach, 1997; Hasenmueller & Criss, 2013; Lovatt & Dugger, 1984). Although boron has a very low toxic effect on mammals, it is very toxic to arthropods and used for insecticides. On the other hand, boric acid another form of boron, is used as an antibiotic in some superficial infections in humans (Irschik et al., 1995).. Boron is an ...
TY - JOUR. T1 - Occurrence of Tourmaline in Metasedimentary Rocks of the Isua Supracrustal Belt, Greenland. T2 - Implications for Ribose Stabilization in Hadean Marine Sediments. AU - Mishima, Shinpei. AU - Ohtomo, Yoko. AU - Kakegawa, Takeshi. PY - 2016/6/1. Y1 - 2016/6/1. N2 - Abiotic formation of RNA was important for the emergence of terrestrial life, but the acknowledged difficulties of generating and stabilizing ribose have often raised questions regarding how the first RNA might have formed. Previous researchers have proposed that borate could have stabilized ribose; however, the availability of borate on the early Earth has been the subject of intense debate. In order to examine whether borate was available on the early Earth, this study examined metasedimentary rocks from the Isua Supracrustal Belt. Garnet, biotite, and quartz comprise the major constituents of the examined rocks. Field relationships and the chemical compositions of the examined rocks suggest sedimentary origin. The ...

Springer Science+Business Media Dordrecht 2015. Palladium complexes of new bidentate N-heterocyclic carbene (NHC) incorporating benzimidazolin- 2-ylidene units have been synthesized and structurally and spectroscopically characterised. The NHC ligands are furnished with aryl substituents on the nitrogen atoms and electron-donating butoxy groups on the benzo-fused ring. The incorporation of these aryl substituents on the bis(NHC) ligands leads to interesting and unexpected conformations around the palladium atoms, and interesting reactivity, including cyclometallation and the formation of a tri-nuclear species. One of the complexes has been studied in an initial series of Mizoroki-Heck and Suzuki-Miyaura cross-coupling reactions but shows moderate to poor activity.. ...
Dear Bo,. Ti2O3, which has a black or blue color, is soluble in concentrated HCl orsulfuric acid. The main oxide form of titanium is TiO2. The dioxide exists in three crystalline states, namely anatase, rutile and brookite. The anatase and rutile forms are soluble in concentrated sulfuric acid, HF, and HF mineral acid combinations.. My favorite combination for dissolving anatase or rutile is 1:1 HF/HNO3 where some heat is generally required to speed dissolution. When the anatase or rutile forms are heated to temperatures at or above 800 °C, they are converted to the brookite form. My experience has been that the brookite form is not soluble in any acids and requires fusion. Fusion with sodium carbonate, pyrosulfate, alkali metal hydroxides, and sodium tetraborate are common. In this case, my favorite is the pyrosulfate fusion using a Pt crucible:. The finely powdered sample is mixed with 35 times its weight of potassium pyrosulfate and heated in a Pt crucible until the melt appears clear. It ...
Making homemade Silly Putty is a hands-on craft experiment for you and your children to enjoy. Many Silly Putty recipes require liquid starch or borax, which are ingredients usually found in the laundry section of most convenience stores. Although borax is a natural mineral that is environmentally-friendly, it can cause skin and eye irritation (see References). Liquid starch also is known to cause eye and skin irritation, as well as nausea and vomiting if ingested (see References). Although neither substance is considered dangerous, there is a safer alternative for making homemade Silly Putty.. ...
Thiazoles and their derivatives have been frequently discovered as a vital component of novel and structurally diverse natural products that exhibit a wide variety of biological activities. The exceptional range of antitumor, antiviral, and antibiotic activities, as well as their presence in peptides, or ability to bind to proteins, DNA, and RNA, have directed numerous synthetic studies and new applications of these heterocycles.The thiazole ring has been identified as a central feature of a myriad of natural products, perhaps the best known being the epothilones. Additionally, thiazoles are frequently appearing in peptide research. Thiazoles can also serve as a protected formyl group that can be liberated in the late stages of a complex natural product synthesis. The presence of a halogen allows these reagents to be used as substrates in various coupling reactions, including Suzuki-Miyaura cross-coupling reactions.Learn More about Thiazoles
|p|The Wittig reaction of carbaldehydes with alkoxycarbonylhalomethylidenetriphenylphosphoranes can be performed with ease in solventless systems. The analogous reaction of carbaldehydes with acylhalomethylidenetriphenylphosphoranes requires a small amount of solvent, such as chloroform, in order for the reaction to proceed. The products of the reaction are versatile precursors for further transformations, such as the Suzuki-Miyaura cross-coupling reaction.|/p|
