INTRODUCTION Mushroom-shaped choroidal melanoma is known to be associated with breaks in Bruch's membrane and is more likely to develop when Bruch's membrane is diseased. The study's goal is to determine if diseases causing breaks in Bruch's membrane predispose a choroidal melanoma to develop into a mushroom-shaped melanoma. MATERIALS AND METHODS A retrospective review of cases of choroidal m...

A four-pixel-array superconducting transition-edge sensor (TES) microcalorimeter with a mushroom-shaped absorber was fabricated for the energy dispersive spectroscopy performed on a transmission electron microscope. The TES consists of a bilayer of Au/Ti with either a 50nm or 120-nm thickness. The absorber of 5.0 μm thick is made from a Au layer and its stem is deposited in the center of the TE...

Although most brain neurons are produced during embryonic and early postnatal development, recent studies clearly demonstrated in a wide range of species from invertebrates to humans that new neurons are added to specific brain structures throughout adult life. Hormones, neurotransmitters, and growth factors as well as environmental conditions modulate this neurogenesis. In this study, we addre...

In dynamical systems with divided phase space, the vicinity of the boundary between regular and chaotic regions is often “sticky,” that is, trapping orbits from the chaotic region for long times. Here, we investigate the stickiness in the simplest mushroom billiard, which has a smooth such boundary, but surprisingly subtle behaviour. As a measure of stickiness, we investigate P (t), the probabi...

The toxicity of two mushroom species found in Finland, Cortinarius speciosissimus and Cortinarius gentilis, on the rat was studied. Dried, homogenized mushroom was given orally by stomach tubing. A dose of 500 mg dried mushroom/kg body weight, was used. It was demonstrated that both species caused renal damage. No damage could be shown in other organs. The renal histopathological changes corres...

Drosophila melanogaster can make appropriate choices among alternative flight options on the basis of the relative salience of competing visual cues. We show that this choice behavior consists of early and late phases; the former requires activation of the dopaminergic system and mushroom bodies, whereas the latter is independent of these activities. Immunohistological analysis showed that mush...

Introduction Linzhi (Ganoderma lucidum) is a well-known medicinal mushroom. This mushroom originated from China becomes the widely used supplementation worldwide. The active ingredient in the mushroom is mentioned for anti-oxidative, glucose controlling and anti-cancerous proliferative activities (1,2). In nephrology, the advantage of Linzhi on kidney is also mentioned. However, the evidence in...

Melon husks are shells usually discarded in large quantities (tonnage) as agricultural waste materials in different parts of Nasarawa State in Nigeria, thereby polluting the environment. An experiment was therefore conducted to determine the nutritional value and effect of utilizing melon husks meal in broiler diets as feed ingredient with or without wild mushroom (Ganoderma sp) and exogenous e...

We have explored the organization of the axonal lobes in Drosophila mushroom bodies by using a panel of immunohistochemical markers. These markers consist of antibodies to eight proteins expressed preferentially in the mushroom bodies: DAMB, DCO, DRK, FASII, LEO, OAMB, PKA RII, and RUT. Previous to this work, four axonal lobes, two projecting dorsally (alpha and alpha') and two medially (beta a...

The mushroom bodies are bilaterally arranged structures in the protocerebrum of Drosophila and most other insect species. Mutants with altered mushroom body structure have been instrumental not only in establishing their role in distinct behavioral functions but also in identifying the molecular pathways that control mushroom body development. The mushroom body miniature(1) (mbm(1)) mutation re...
