The effectiveness of three kinds of enzymes (chitinase, β-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the β-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the...

Functional imaging with genetically encoded calcium and cAMP reporters was used to examine the signal integration underlying learning in Drosophila. Dopamine and octopamine modulated intracellular cAMP in spatially distinct patterns in mushroom body neurons. Pairing of neuronal depolarization with subsequent dopamine application revealed a synergistic increase in cAMP in the mushroom body lobes...

Objective(s): In previous studies, antioxidant activity of Viola odorata L. has been demonstrated. In this study, we have investigated the anti-melanogenic effect of extract and fractions of the plant in B16F10 cell line. Materials and Methods: Impact of different increasing concentrations of extract and fractions of V. odorata was evaluated on cell viability, cellular tyrosinase, melanin conte...

BACKGROUND During development neurons are generated by sequential divisions of neural stem cells, or neuroblasts. In the insect brain progeny of certain stem cells form lineage-specific sets of projections that arborize in distinct brain regions, called clonal units. Though this raises the possibility that the entire neural network in the brain might be organized in a clone-dependent fashion, o...

Detection of the cause of dietetic ileus is often difficult. High quality computed tomography (CT) scanning has improved our ability to precisely diagnose a large variety of intra-abdominal and intraluminal disease processes, including the presence of foreign bodies [1]. Here we report a case of ileus caused by ingestion of shiitake mushroom that could be diagnosed before treatment and could be...

Breast cancer is the most commonly diagnosed cancer among women in Western countries. Currently, there is no effective therapy for malignant estrogen-independent breast cancer. We have screened 38 species of edible mushroom on human estrogen-receptor positive (MCF-7) and estrogenreceptor negative (MDA-MB-231, BT-20) breast cancer cells to select potential agents with broad-spectrum antitumor ac...

This study reports depigmenting potency of 1,3-selenazol-4-one derivatives, which would be based upon the finding of direct inhibition to mushroom tyrosinase. 1,3-Selenazol-4-one derivatives exhibited inhibitory effect on dopa oxidase activity of mushroom tyrosinase. In this study, inhibitory effects of six kinds of 1,3-selenazol-4-one derivatives (A, B, C, D, E and F) on mushroom tyrosinase we...

Medicinal and edible mushrooms have been widely used for centuries as nutraceuticals to improve health and to treat numerous diseases. Several species of mushrooms such as Lentinula edodes, Schizophyllum commune, Ganoderma lucidum and Coriolus versicolor have been used as immunostimulators and anticancer agents. Mushroom polysaccharides, as the main active ingredient in the mushroom, belong to ...

In most heterothallic mushroom species, inbreeding is avoided by an incompatibility system determined by two loci each with multiple alleles (the A and B mating-type loci). In this study we investigated the genetic structure of the mating-type loci in the tropical oyster mushroom Pleurotus djamor using both positional cloning and degenerate PCR methods. DNA sequences from genomic regions cosegr...
