Hericium erinaceus is an edible and medicinal mushroom with potential neuroprotective effects. The study of H. erinaceus has attracted considerable attention during the past 10 years, particularly with regard to its potential utility in the treatment of motor dysfunction, Alzheimer disease, and other forms of dementia. We previously determined that oral supplementation with H. erinaceus results in significant improvements in novelty-seeking behavior and novel object recognition in mice. In this study, H. erinaceus was added to the diets of wild-type mice for 2 months, and effects on spatial memory were evaluated by means of a Y maze and an object location task...

Hericium erinaceus is a popular culinary and medicinal mushroom in China because of its broad beneficial effects. In this study we evaluated the effects of stimulation with 7 growth regulators at 5 different concentrations on improving the production of nutritional and bioactive compounds by H. erinaceus. Results showed that among all the tested regulators, gibberellic acid (GA) increased protein content (165%), free amino acids (100%), polysaccharides (108%), and polyphenols (26%). Spraying nephthyl acetic acid increased polysaccharides and triterpenoids to 4...

Basidiomycetes of the genus Hericium are among the most praised medicinal and edible mushrooms, which are known to produce secondary metabolites with the potential to treat neurodegenerative diseases. This activity has been attributed to the discovery of various terpenoids that can stimulate the production of nerve growth factor ( NGF ) or (as established more recently) brain-derived neurotrophic factor ( BDNF ) in cell-based bioassays. The present study reports on the metabolite profiles of a Lion's Mane mushroom ( Hericium erinaceus ) strain and a strain of the rare species, Hericium flagellum (synonym H...

Jellyfish-induced gill pathology relies upon occasional diagnostic observations yet the extent and impact of jellyfish blooms on aquaculture may be significant. Idiopathic gill lesions are often observed in apparently healthy fish. This study exposed Atlantic salmon (Salmo salar L.) smolts to macerated Cyanea capillata at 2.5 and 5 g/L for 2 hr under controlled laboratory conditions. Blood chemistry and gill histopathology were examined over a subsequent 4-week period. Fish showed an acute response to the presence of jellyfish, including characteristic external "whiplash" discoloration of the skin and acute increases in blood electrolytes and CO2 concentration; however, these were resolved within 4 days after exposure...

Hericium erinaceus is well known for the neurotrophic effect it confers by promoting nerve growth factor biosynthesis. We discovered a novel bioactivity of H. erinaceus in its ability to suppress adenosine triphosphate (ATP)-induced calcium signaling in neuronal PC12 cells. ATP, known primarily as a neurotransmitter, also acts on purinoceptors (P2 purinergic receptor [P2R]) to generate the cellular calcium signaling and secretion that mediate P2R physiological manifestations, including pain. Chronic pain reduces quality of life...

The volatile constituents of the fruiting bodies of 4 culinary-medicinal mushroom species (Agaricus bisporus, Boletus edulis, Cantharellus cibarius, and Hericium erinaceus) from Hungary were examined to review their aroma composition. Simultaneous distillation/extraction was applied to extract volatile compounds from fungi, and the values were measured with gas chromatography--mass spectrometry. Although the fragrances of fungi are not as characteristic as those of spices, several groups of volatile compounds have been found in mushrooms...

Lion's mane jellyfish ( Cyanea capillata ) stings cause severe pain and can lead to dangerous systemic effects, including Irukandji-like syndrome. As is the case for most cnidarian stings, recommended medical protocols in response to such stings lack rigorous scientific support. In this study, we sought to evaluate potential first aid care protocols using previously described envenomation models that allow for direct measurements of venom activity. We found that seawater rinsing, the most commonly recommended method of tentacle removal for this species, induced significant increases in venom delivery, while rinsing with vinegar or Sting No More® Spray did not...

It has been proposed that there is a thermal cost of the mane to male lions, potentially leading to increased body surface temperatures ( T s ), increased sperm abnormalities, and to lower food intake during hot summer months. To test whether a mane imposes thermal costs on males, we measured core body temperature ( T b ) continuously for approximately 1 year in 18 free-living lions. There was no difference in the 24-hr maximum T b of males ( n  = 12) and females ( n  = 6), and males had a 24-hr mean T b that was 0...

Neurodegenerative disease is defined as a deterioration of the nervous system in the intellectual and cognitive capabilities. Statistics show that more than 80-90 million individuals age 65 and above in 2050 may be affected by neurodegenerative conditions like Alzheimer's and Parkinson's disease. Studies have shown that out of 2000 different types of edible and/or medicinal mushrooms, only a few countable mushrooms have been selected until now for neurohealth activity. Hericium erinaceus is one of the well-established medicinal mushrooms for neuronal health...

OBJECTIVE: Although the endonasal endoscopic approach has been applied to remove olfactory groove meningiomas, controversy exists regarding the efficacy and safety of this approach compared with more traditional transcranial approaches. The endonasal endoscopic approach was compared with the supraorbital (eyebrow) keyhole technique, as well as a combined "above-and-below" approach, to evaluate the relative merits of each approach in different situations. METHODS: Nineteen cases were reviewed and divided according to operative technique into 3 different groups: purely endonasal (6 cases); supraorbital eyebrow (microscopic with endoscopic assistance; 7 cases); and combined endonasal endoscopic with either the bicoronal or eyebrow microscopic approach (6 cases)...
