Disease relevance of oxalic acid

• Effects of potassium oxalate on dentin hypersensitivity in vivo [1].
• PO combined with mineral fertilizer has no negative effects on nitrogen-fixing bacteria Azotobacter and oligo-nitrophilic bacteria [2].

High impact information on oxalic acid

• The plasma membranes are not permeable to potassium oxalate but the Ca2+ uptake was stimulated by potassium oxalate in intracellular membranes [3].
• Potassium oxalate treatment also reduced the dentin permeability to 8 +/- 3% [4].
• Guinea-pig hepatocytes whose plasma membranes were rendered permeable by treatment with saponin, accumulated 45calcium in the presence of potassium oxalate and ATP [5].
• The method included extraction of flavone C-glucosides from AOB-fortified foods by methanol aqueous solution, deproteinating with saturated lead acetate solution and potassium oxalate, defatting with n-hexane and clean-up by solid-phase extraction (SPE) with Phenomenex C18 cartridges [6].
• Blood samples were collected during controlled drinking sessions using 10-mL venipuncture tubes containing 100 mg of sodium fluoride and 20 mg of potassium oxalate and were analyzed by headspace gas chromatography [7].

Chemical compound and disease context of oxalic acid

• Effects of pre- or post-application of calcium chloride on occluding ability of potassium oxalate for the treatment of dentin hypersensitivity [8].
• The treatments tested were experimental pastes, gels and solutions of phytocomplexes (extracted from rhubarb, spinach and mint), an experimental paste containing 5% potassium oxalate, and two commercial toothpastes recommended for dentinal hypersensitivity (Elmex and Sensodyne) [9].

Anatomical context of oxalic acid

• Dentin disks treated by the calcium phosphate precipitation method, and disks treated with potassium oxalate, NaF, and SrCl2 solutions, were immersed in synthetic saliva, which was regularly replenished so that ionic concentration would be maintained [4].
• These results suggest that papaverine potentiated Ca-uptake by membranes such as sarcoplasmic reticulum, in the presence of potassium oxalate and inhibited Ca-uptake by the plasma membrane-derived vesicles in the absence of potassium oxalate [10].
• The barley root (Hordeum vulgare) of 3-day old seedlings were treated with potassium oxalate to study the distribution of calcium among plant cell organelles [11].
• The precipitation reaction with potassium oxalate was used to investigate the subcellular localization of Ca2+ in atrial myocardocytes and in Schwann cells of non-myelinated nerve fibers [12].
• Twenty consecutive amniotic fluid samples were sent to the laboratory in two vials, the first without additive and the second with potassium oxalate to prevent metabolic activity, to assess the effect of cellular metabolism and time delay on amniotic fluid glucose concentrations [13].

Associations of oxalic acid with other chemical compounds

• Sodium fluoride at all concentrations, with or without refrigeration and potassium oxalate, effectively inhibited cocaine degradation, with 86-91% of the drug present after 48 h [14].
• Randomly labeled plasma samples were placed in vials containing 2% sodium fluoride and 1% potassium oxalate, immediately refrigerated, and analyzed for cocaine and tetracaine using gas chromatography and mass spectroscopy [15].
• The groups corresponded to the following experimental materials: 3% potassium oxalate gel-pH 4; 6% potassium oxalate gel-pH 4; 3% potassium oxalate gel-pH 2.5 and 1.23% fluoride gel (APF gel)-pH 3.6-3.9, applied to dentin under the following surface conditions: air-dried, blot-dried, wet, EDTA air-dried; EDTA blot-dried [16].
• Statistical analysis by repeated measures ANOVA for univariate tests of hypothesis for within subject effects showed the sodium chloride solution was more effective in reducing dentin sensitivity than the potassium oxalate solution [17].
• In addition, the composition of the precipitate formed when mixing potassium oxalate and calcium chloride was analyzed with a powder x-ray diffractometer (XRD) [8].

Gene context of oxalic acid

• METHODS: Madin-Darby canine kidney cells were exposed to potassium oxalate or COM crystals in the presence or absence of HGF [18].

Analytical, diagnostic and therapeutic context of oxalic acid

• The purpose of this study was to longitudinally evaluate the occlusion of dentinal tubules by various clinical procedures including scaling and root planing and the application of potassium oxalate [19].
• Effect of commercially available and experimental potassium oxalate-based dentin desensitizing agents in dentin permeability: influence of time and filtration system [20].
