OBJECTIVES To assess the efficacy of dust respirators in preventing asthma attacks in patients with occupational asthma (asthma induced by buckwheat flour or wheat flour). METHODS The effect of the work environment was examined in two patients with occupational asthma with and without the use of a commercially available mask or a dust respirator. Pulmonary function tests were performed immedi...

Buckwheat (Fagopyrum esculentum Moench) noodles are a traditional food in Japan and contains catechin, epicatechin, quercetin, rutin and an oligomer of catechin and epicatechin. Catechin, epicatechin, quercetin and rutin have flavonoid structures, and their antioxidant action and neuroprotection have been widely studied. Buckwheat extract (BWE) has been also reported to have antioxidant activit...

Fagopyrum homotropicum Ohnishi is a self-pollinating wild buckwheat species indigenous to eastern Tibet and the Yunnan and Sichuan Provinces of China. It is useful breeding material for shifting cultivated buckwheat (F. esculentum ssp. esculentum Moench) from out-crossing to self-pollinating. Despite its importance as a genetic resource in buckwheat breeding, the genetic variation of F. homotro...

The consumption of products made from Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) has increased in recent years in Japan. Increased consumer demand has led to recognition of the need for early varieties of this crop with high and stable yields. In order to accomplish this, more information is needed on the genetic mechanisms affecting earliness and yield. We conducted genetic analysis ...

Adult parasitoids of pest insects rely on floral resources for survival and reproduction, but can be food-deprived in intensively managed agricultural systems lacking these resources. Stink bugs are serious pests for crops in southwest Georgia. Provisioning nectar-producing plants for parasitoids of stink bugs potentially can enhance biocontrol of these pests. Knowledge of spatial and temporal ...

Quantitative reverse transcription PCR (qRT-PCR) is one of the most precise and widely used methods of gene expression analysis. A necessary prerequisite of exact and reliable data is the accurate choice of reference genes. We studied the expression stability of potential reference genes in common buckwheat (Fagopyrum esculentum) in order to find the optimal reference for gene expression analys...

Photoperiod sensitivity is an important trait related to crop adaptation and ecological breeding in common buckwheat (Fagopyrum esculentum Moench). Although photoperiod sensitivity in this species is thought to be controlled by quantitative trait loci (QTLs), no genes or regions related to photoperiod sensitivity had been identified until now. Here, we identified QTLs controlling photoperiod se...

Behavioral responses of S. zeamais to odours from pulverized wheat, brown rice, sorghum, buckwheat, peanut and cork were compared in a Y-tube-olfactometerbioassay. Results showed that both sexes responded to host volatiles and males were more sensitive than females. The strongest responses to grains of wheat and brown rice were found, and insects reared on these were dramatically heavier than o...

ABSTRACT The effect of alkaloids fumitremorgin С (1), 12,13-dihydroxyfumitremorgin C (2), verruculogen (3), spirotryprostatin А (4), 6-methoxyspirotryprostatin В (5), spirotryprostatin F (6), fumiquinazoline С (7), bisdethiobis(methylthio)gliotoxin (8), and tryptoquivaline F (9) from the marine-derived strain of the fungus Aspergillus fumigatus on the growth of sprout roots of buckwheat at the ...
