The remedies employed in the treatment of common warts have ranged from magic charms to surgical excision, and acids, electricity, carbon dioxide snow and radium have all produced good results in many cases. However, when a large number of warts are present, local destructive measures are tedious and painful and, in children, such treatment is difficult to carry out. Case.-?A girl, aged about 1...
A simple solvent-free protocol for the preparation of flunixin, a potent non-narcotic, non-steroidal anti-inflammatory drugs is reported using boric acid as catalyst. Its salt, flunixin meglumine are then prepared under reflux in EtOH. This sustainable method are then extended for the synthesis of a series of 2-(arylamino) nicotinic acid derivatives. The present protocol combines non-hazardous ...
In Germany the addition of the trace element boron as boric acid or borax to food supplements was not permitted up to now. However, this situation could soon change since the laws in the EU Member States are to be approximated and its addition is permitted in other European countries. If this happens, boron could also go on the market in Germany as an ingredient in food supplements. Against thi...
Studies were conducted on the enhancement of pathogenicity of Bacillus thuringiensis by 1% boric acid against various species of termites. The increase in virulence of Serratia marcescens by 1% Potassium chloride or 1% Sodium citrate against the workers of M. championi has also been established. The increase in virulence is confirmed by the enhancement ratios, which are ranging from about 1.5 t...
BACKGROUND In urine, factors such as timing of voids, and duration at room temperature (RT) may affect the quality of recovered protein and metabolite data. Additives may aid with detection, but can add more complexity in sample collection or analysis. We aimed to identify the optimal urine processing protocol for clinically-obtained urine samples that allows for the highest protein and metabol...
1. The rate of the saponification of iodoacetic acid in sodium hydroxide and alkaline buffer solutions yielding glycollic acid was measured by means of Heyrovský's polarographic method. 2. From the bimolecular velocity constants, increasing with the ionic strength of the solution, the Brönsted factor, F, which characterizes the primary salt effect, was calculated. 3. In the borate buffer soluti...
Under chloroform the intestines were washed with warm boric lotion and carefully put back into the abdominal cavity. There were a few small splinters of wood found in the su1 perficial wound, which were carefully removed, | and the wound washed clean with warm boric lotion The peritoneum was sutured with aseptic catgut and skin with horse-hair ; thoroughly dusted with iodoform and dressed. Opiu...
a computational study of the electronic structure and stability of complexes formed between zeolite y and boric acid was carried out at the hf and b3lyp levels using 6-31g* basis set. five structures located as local minimum in pes of complex (structures d, e, f, g, and h). the most stable structure is formed due to hydrogen bonding between two hydroxyl of boric acid and both oxygen of ...
In an attempt to decrease ascorbate interference on the ion-chromatographic determination of urinary oxalate, we compared the effectiveness of four different methods for ascorbate elimination by analyzing a representative urine pool supplemented with successive ascorbate additions. Two of the methods--treatment with ferric ions or boric acid--have been described elsewhere; treatments with nitri...
Growth behavior of Clostridium botulinum type E beluga was studied in Acipenser persicus granular caviar treated with 5% NaCl, 5%NaCl plus 0.3% boric acid and 0.4%borax and 5%NaCl plus 0.15% methyl paraben incubated at temperatures -2, 5 and 15 °C for 224 days. The initial number of inoculated bacterial spore was 5.1×104 cfu/g caviar in each treated sample. The number of bacterial spores in sam...
