Benzbromarone (BBR) is a hepatotoxic drug, but the detailed mechanism of its toxicity remains unknown. We identified 2,6-dibromohydroquinone (DBH) and mono-debrominated catechol (2-ethyl-3-(3-bromo-4,5-dihydroxybenzoyl)benzofuran; CAT) as novel metabolites of BBR in rat and human liver microsomal systems by comparison with chemically synthesized authentic compounds, and we also elucidated that ...
The relationship between a tree's crown radius and diameter at breast height (DBH) has a variety of uses including forest competition studies, tree crown densities, spacing and stoclung relationships, wildlife habitat suitability models, and tree volume estimations. Estimating DBH from mean crown radius (MCR) is of interest to natural resource managers because MCR can be estimated from high res...
Dalbergia tonkinensis is being promoted in Vietnam for the future supply of prized wood furniture and chemical extraction. Expansion plantation area requires a reliable source quality seed. This study evaluates field performance progeny from mature mother trees natural forests urban environments. Trials were established Tan Son Doan Hung districts Phu Tho province assessed 3 years later. There ...
The relationship of serum dopamine-(-hydroxylase (DBH), plasma renin activity (PRA) and urinary catecholamines (IU catechols) in various forms of essential hypertension (EHT) (low, normal and high renin) was evaluated. Eighty-four predominantly white, young (37 ± 8 years (SD)), mildly hypertensive patients (diastolic pressure 93 ± 4 mm Hg (SD)) continued their regular diet and received no medic...
The relationship of serum dopamine-beta-hydroxylase (DBH), plasma renin activity (PRA) and urinary catecholamines (IU catechols) in various forms of essential hypertension (EHT) (low, normal and high renin) was evaluated. Eighty-four predominantly white, young (37 +/ 8 years (SD)), mildly hypertensive patients (diastolic pressure 93 +/- 4 mm Hg (SD)) continued their regular diet and received no...
Objective: Interaction between genetic and environmental factors is considered as major factors in Schizophrenia (SCZ). It has been shown that dopaminergic and noradrenergic neurotransmission dysfunction play an essential role in the SCZ pathogenesis. This study aimed to find the impact of functional 19-bp insertion/deletion (ins/del) polymorphism in dopamine beta-hydroxylase (DBH) gene on SCZ ...
BACKGROUND Increased dopaminergic activity may play a primary role in psychotic depression. Dopamine beta-hydroxylase (DbetaH) catalyses the key step in biosynthesis of the neurotransmitter noradrenaline from dopamine, and low DbetaH activity is a possible risk factor for developing psychotic depression. An exon 2 polymorphism (DBH*444 g/a) of the DbetaH gene (DBH) is significantly associated w...
1. Resting plasma dopamine B-hydroxylase (DBH) activity and haemodynamic parameters were studied in untreated borderline (twenty-nine) and permanent (twenty-seven) essential hypertensive patients. DBH was also measured in sixty-three apparently healthy subjects. 2. Mean DBH values were not significantly different between the groups. 3. Cardiac output, cardiopulmonary blood volume and the cardio...
Under long-term hypoxia, noradrenaline (NA) content in the carotid body (CB) increases, suggesting that NA plays an important role in CB chemotransduction. However, it is unknown whether short-term hypoxia upregulates NA biosynthesis in CB. Therefore, we examined dopamine β-hydroxylase (DBH) expression in the CB of rats exposed to hypoxia (10% O(2)) for 0 to 24 hr with immunoblotting and immuno...
Several studies suggest that some bark beetle like to attack large trees. The invasive red turpentine beetle (RTB), Dendroctonus valens LeConte, one of the most destructive forest pests in China, is known to exhibit this behavior. Our previous study demonstrated that RTBs preferred to attack large-diameter trees (diameter at breast height, DBH ≥30 cm) over small-diameter trees (DBH ≤10 cm) in t...
