background tyrosinase, as a copper-containing enzyme, is widely distributed in different levels of life span. it is also a key enzyme in melanin biosynthesis, which plays a crucial role in determining the color of mammalian skin and hair. objectives the current study aimed to determine the effect of a palladium complex on cresolase and catecholase reactions of mushroom tyrosinase (mt). material...

Background: Poisoning by different kinds of toxic mushrooms is unfortunately becoming an increasingly important medical problem, evident from the growing number of reports worldwide since the 1950s. Mycetism being a health concern, deserves scientific attention. In this perspective, the present study aims to assess the potential effects of ingesting the selected wild mushrooms from regions of t...

We examined the development of olfactory neuropils in the hemimetabolous insect Locusta migratoria with an emphasis on the mushroom bodies, protocerebral integration centers implicated in memory formation. Using a marker of the cyclic adenosine monophosphate (cAMP) signaling cascade and lipophilic dye labeling, we obtained new insights into mushroom body organization by resolving previously unr...

In humans KCNQ2/3 heteromeric channels form an M-current that acts as a brake on neuronal excitability, with mutations causing a form of epilepsy. The M-current has been shown to be a key regulator of neuronal plasticity underlying associative memory and ethanol response in mammals. Previous work has shown that many of the molecules and plasticity mechanisms underlying changes in alcohol behavi...

One of the newest technologies for storing agricultural products is the biodegradable packagingmethod, in which certain materials are utilized on a nano scale. Edible mushroom is a nutritious agriculturalproduct which can be considered a food source as well as having medicinal applications while having a shortshelf life after harvesting. In this study, the mushroom was packaged in polylactic ac...

Phylogenetically conserved brain centers known as mushroom bodies are implicated in insect associative learning and in several other aspects of insect behavior. Kenyon cells, the intrinsic neurons of mushroom bodies, have been generally considered to be disposed as homogenous arrays. Such a simple picture imposes constraints on interpreting the diverse behavioral and computational properties th...

BACKGROUND The mushroom bodies of the insect brain play an important role in olfactory processing, associative learning and memory. The mushroom bodies show odor-specific spatial patterns of activity and are also influenced by visual stimuli. METHODOLOGY/PRINCIPAL FINDINGS Functional imaging was used to investigate changes in the in vivo responses of the mushroom body of the hawkmoth Manduca ...
