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...

Abstract Mushroom bodies are known from annelids and arthropods were formerly assumed to argue for a close relationship of these two taxa. Since molecular phylogenies univocally show that both taxa belong different clades in the bilaterian tree, similarity must either result convergent evolution or transformation an ancestral mushroom body. Any morphological differences ultrastructure compositi...

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...

Among insects, learning is particularly well studied in the fruit fly Drosophila melanogaster and the honeybee Apis mellifera. A senescence-dependent decline in classic pavlovian conditioning is demonstrated for both species. To understand how aging affects learning, genetic approaches used with Drosophila can benefit from complementary studies in Apis. Specifically, honeybees have a larger bra...

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 ...
