The shiitake mushroom has gained popularity in the last decade, ranking second in the world for mushrooms consumed, providing consumers with a wide variety of nutritional and healthy benefits. It is often not clear the origin of these mushrooms, so it becomes of great importance to the consumers. In this research, different machine learning algorithms were developed to determine the geographical origin of shiitake mushrooms () consumed in Korea, based on experimental data reported in the literature (δC, δN, δO, δS, and origin). Regarding the origin of shiitake in three categories (Korean, Chinese, and mushrooms from Chinese inoculated sawdust blocks), the random forest model presents the highest accuracy value (0.940) and the highest kappa value (0.908) for the validation phase. To determine the origin of shiitake mushrooms in two categories (Korean and Chinese, including mushrooms from Chinese inoculated sawdust blocks in the latter ones), the support vector machine model is chosen as the best model due to the high accuracy (0.988) and kappa (0.975) values for the validation phase. Finally, to determine the origin in two categories (Korean and Chinese, but this time including the mushrooms from Chinese inoculated sawdust blocks in the Korean ones), the best model is the random forest due to its higher accuracy value (0.952) in the validation phase (kappa value of 0.869). The accuracy values in the testing phase for the best selected models are acceptable (between 0.839 and 0.964); therefore, the predictive capacity of the models could be acceptable for their use in real applications. This allows us to affirm that machine learning algorithms would be suitable modeling instruments to determine the geographical origin of shiitake.

An edible Mushroom-Nafion modified glassy carbon electrode (MN-GCE) was prepared using a homogeneous mixture varying the concentrations of these, in addition to the origin of the mushroom (Shiitake, Lentinula edodes, M and Abrantes, Agariscus bisporus, M) and applied to the As(III) determination by anodic stripping voltammetry. After choosing the optimal conditions in the preparation of the electrode, the second stage was to study the effects of various parameters such as supporting electrolyte, pH, accumulation potential, and time (E, t). The optimum experimental conditions chosen were Britton Robinson buffer 0.

Background: The immune system is critical in fighting cancer, so is it possible that the natural stimulation of this system can slow down or stop the evolution of cancer? Our in vivo study aimed to evaluate the protective effect of the combination of five types of immunostimulants, which are Beta-glucan and Arabinogalactan as polysaccharides and three mushroom extracts (Reishi, Maitake, and Shiitake), on 7,12-Dimethyl Benz[a]anthracene (DMBA)/ Croton oil-induced papilloma in Swiss albino mice.
Methodology: We used blood count analyses to estimate broadly the immunological reaction and biochemical techniques to determine the oxidative stress variations in the enzymatic activity of Superoxide dismutase (SOD), Catalase (CAT), and Glutathion peroxidase (GPx), which could have a preventive function against cancer development.
Results: The cutaneous application of the DMBA/Croton oil caused precancerous hyperplasia in squamous cells (papilloma) on the back of the mice.

Mushrooms and derivates are well known to the scientific community for having different health benefits and exhibit a wide range of pharmacological activities, including lipid-lowering, antihypertensive, antidiabetic, antimicrobic, antiallergic, anti-inflammatory, anticancer, immunomodulating, neuroprotective and osteoprotective actions. In Europe, medical mushrooms are mainly marketed in the form of food supplements as single components or combined with other nutraceuticals. In this context, the first peculiarity that distinguishes it is the safety established through the "history of consumption" that characterizes that mushroom.

Background: Computational tools may have an edge over conventional methods for the preliminary evaluation of food allergenicity. In this study, the allergenic potential of Lentinula edodes was evaluated and validated using in silico tools.
Results: The potential cross-reactivity of mushroom proteins with fungal allergens was determined using sequence alignment - the Fast Alignment (FASTA) and Basic Local Alignment Search Tool (BLAST) algorithm.
