Selective Conversion ofm-Hydroxybenzyl Alcohol to m-Hydroxybenzaldehyde

The Conversion of P-hydroxybenzaldehyde to the Benzoquinone Ring of Ubiquinone in Rhodospirillum Rubrum.

The pathways involved in the biosynthesis of the benzoquinone ring of the ubiquinones have not been established. Recognition of the inability of mammals to synthesize aromatic rings de nova has led to the supposition that, in mammals, the benzoquinone ring of the ubiquinones arises from dietary aromatic amino acids. In support of this theory, Bentley et al. (1) administered phenylalanine-U-Cl4 ...

ofM mode derived indices

Objective-To compare M mode derived indices of left ventricular performance obtained with transthoracic and transoesophageal echocardiography in children with congenital heart disease. Design-Transthoracic and transoesophageal M mode echocardiograms were obtained under general anaesthesia before cardiac catheterisation. Recordings were digitised by dedicated software. Indices of cavity dimensio...

Anaerobic Degradation of m-Cresol by a Sulfate-Reducing Bacterium.

m-Cresol metabolism under sulfate-reducing conditions was studied with a pure culture of Desulfotomaculum sp. strain Groll. Previous studies with a sulfate-reducing consortium indicated that m-cresol was degraded via an initial para-carboxylation reaction. However, 4-hydroxy-2-methylbenzoic acid was not degraded by strain Groll, and no evidence for ring carboxylation of m-cresol was found. Stra...

4-Hydroxybenzyl Alcohol Prevents Epileptogenesis As Well As Neuronal Damage in Amygdaloid Kindled Seizures

Background: 4-Hydroxybenzyl alcohol (4-HBA), one of the major active phenolic constituents of Gastrodia elata Blume, has been shown to be a neuroprotective agent. Previous studies have demonstrated the anticonvulsive effect of Gastrodia elata, while no studies have investigated the antiepileptogenic effect of 4-HBA. Methods: We examined the effect of 4-HBA (25 mg/kg, 50 mg/kg or 100 mg/kg i.p.)...
