The dehydration of glucose and other hexose carbohydrates to 5-(hydroxymethyl)furfural (HMF) was investigated in imidazolium-based ionic liquids with boric acid as a promoter. A yield of up to 42% from glucose and as much as 66% from sucrose was obtained. The yield of HMF decreased as the concentration of boric acid exceeded one equivalent, most likely as a consequence of stronger fructose-bora...

Freeze-dried, granular sugar baits containing boric acid as the toxicant were evaluated against house flies, Musca domestica L., in two bioassays with toxicant dose ranges of 3, 5, 7, 8, and 12%, and 3, 5, 9, 17, and 33% boric acid, respectively, calculated and expressed on a dry weight basis. Flies in bioassay 1 were mixed sex and unstarved and flies in bioassay 2 were females only and starved...

We have reported the fabrication of boric acid incorporated into surface of magnetite nanoparticles. The catalyst was characterized using spectroscopic, magnetic and thermal techniques (FT-IR, SEM, XRD, ICP, VSM and TGA). It catalyzed Mukaiyama aldol reaction of a ketene silyl acetal type nucleophile ((1-methoxy-2-methylprop-1-enyloxy) trimethylsilane), and various aldehydes (aromatic, aliphati...

Various concentrations (100, 500, 1000, 5000 and 10000 ppm) of boric acid were tested in laboratory to check its potential as a slow-acting toxicant against subterranean termite, Heterotermes indicola (Rhinotermitidae: Isoptera). Under the tested concentrations, ELT 50 (Effective Lethal Dose to kill 50% of the exposed termites) values ranged from 2.7 to 5.4 days while ELT 90 were 4.5 and 9.1 da...

Boron (B) is essential in plants but often present at low concentrations in the environment. To investigate how plants survive under conditions of B limitation, we conducted a transcriptome analysis and identified NIP5;1, a member of the major intrinsic protein family, as a gene upregulated in B-deficient roots of Arabidopsis thaliana. Promoter-beta-glucuronidase fusions indicated that NIP5;1 i...

BACKGROUND Boric acid is widely used in biology, but its body weight reducing effect is not researched. METHODS Twenty mice were divided into two equal groups. Control group mice drank standard tap water, but study group mice drank 0.28mg/250ml boric acid added tap water over five days. Total body weight changes, major organ histopathology, blood biochemistry, urine and feces analyses were co...

Accidental poisoning is not always recognized. If there is no leading history of the ingestion or exposure to poison the signs can easily be misinterpreted. In this way boric acid poisoning of infants may remain unsuspected, especially when it occurs by absorption through the skin. Boric acid has been in clinical use as an antiseptic for 80 years. Soon after its introduction for this purpose by...

A unidimensional thin-layer chromatography system for the separation of phospholipids has been developed. The method employs precoated plates impregnated with boric acid and is capable of resolving eight phospholipid standards, including phosphatidylinositol, phosphatidylserine, and phosphatidylglycerol. Liver, kidney, and platelet phospholipids of the rat were resolved into six major classes u...

To the best of our knowledge, this is the first study concerning the effect of boric acid (BA) administration on fetal alcohol syndrome (FAS). In this study, the aim was to investigate prenatal alcohol-induced oxidative stress on the cerebral cortex of newborn rat pups and assess the protective and beneficial effects of BA supplementation on rats with FAS. Pregnant rats were divided into three ...

□ The medicated hydrogels were prepared aseptically under moist heat treatment using polyvinylpyrrolidone (PVP), sodium-carboxymethylcellulose (CMC), polyethyleneglycol (PEG), agar, glycerin and/or boric acid (BA) and designated as PVP-CMC and PVP-CMC-BA. The aim of this study was to develop some medicinal values-based hydrogels. BA was used to build up the medicinal values (antiseptic and anti...
