Tremella fuciformis Berk (TF) is a common edible and medicinal mushroom, and has long been used in food and in Chinese medicine. It possesses anticancer, anti-inflammation, anti-oxidative, and neuroprotective abilities. Since their cultivation is a problem, TFs in Taiwan are primarily imported from China, which has a problem with pesticide residues. Thus, the question of whether the Taiwan cultivated TFs, T1, and T6 showed similar or even better results than TFs from China (CH) was assessed in the present study. The results of the physicochemical tests of these TFs showed that T1 extracted by hot water (T1H) has the highest concentration of polysaccharide; meanwhile, T6 extracted by cold water (T6C) showed the highest amount of protein. Regarding the immune modulatory effects of these TFs, hot water extracts of these TFs augmented significantly the inducible nitric oxide synthetase (iNOS), interleukin (IL)-6, and tumor necrosis factor (TNF)-[Formula: see text] mRNA expression than those of cold water extracts. On the other hand, the cold water extracts of TFs, especially of T1C, obviously suppressed cancer cell survival better than those of hot water extracts. Interestingly, we found that hot water extracts of TFs may augment necrotic cell death, whereas, cold water extracts of TFs induce apoptosis. Furthermore, we also showed that these TFs activate caspase-3 cleavage, up regulate the Bax/Bcl-2 ratio, and decrease MMP-9 expressions in PC-3 cells. Taken together, our results indicated that T1 and T6 strains of TFs showed the similar immune modulatory and anticancer abilities were better than the CH strain of TFs.

Cold Water Temperature

In the present work, results of experimental research on the mains water temperature supplying the Solar Domestic Hot Water system in the period from 2016 to 2018 are shown. The test object is located in the Hotel for Research Assistants on Bialystok University of Technology campus in Poland. One of the elements that will guarantee the correct energy balance of a hot tap-water system is the exact determination of the cold water temperature. The aim of this study is estimation of the temperature of the mains water flowing into the district heating substation and the water feeding directly the heat storage tanks. The research results showed that the average value of the cold water was 14.09°C during the 3 years of measurements. Moreover, it was shown that this temperature increased by about 0.4°C as a result of heat exchange with the air inside the substation. In the article, the author proposed modifications of coefficients in a commonly used model developed by National Renewable Energy Laboratory for determining the temperature of mains water in energy simulations. The proposed changes allow for accurate modelling of the cold water temperature under the climate conditions of north-eastern Poland.

Chroogomphis rutillus is an ectomycorrhizal edible mushroom available in China. The ethanolic, cold water and hot water extracts were prepared and their antioxidant properties studied. At 4 mg/mL, the ethanolic extract showed a high reducing power of 1.561, whereas those of cold water and hot water extracts were 1.161 and 0.808. With regard to the scavenging ability on 1,1-diphenyl-2-picrylhydrazyl radicals, extracts were effective in the order: ethanolic > cold water > hot water extracts. EC50values for chelating ability on ferrous ions for ethanolic, cold water and hot water extracts were 15.755, 0.059, and 0.067 mg/mL, respectively. Based on EC50values, the various extracts from C. rutillus were effective antioxidants.

Lentinan, 1152 Dalton β-D-glucan found in Shiitake Mushroom (Lentinus edodes), has been claimed to have anticancer and immunomodulatory activity. Several extraction methods have been used by researchers to isolate Lentinan including hot water and alkaline solution (1.25 M NaOH). In this study, hot water and alkaline solution (1.25 M NaOH) were used to extract the Lentinan-like β-D-glucan (1151 Dalton) from Tiger’s Milk Mushroom, Termite Mushroom, and selected local market mushrooms. The isolated Lentinan-like β-D-glucan from both hot water and alkaline solution was analyzed by LCMS-QTOF. Commercial Lentinan standard from Lentinus edodes was used as a reference. The results showed significant differences on chromatogram patterns of Lentinan-like β-D-glucan between both extracts. The peak of Lentinan-like β-D-glucan was only found in isolated polysaccharide glucan of hot water extracts. The isolated polysaccharide glucans from Tiger’s Milk Mushroom and Termite Mushroom were found to have 0.74±0.12 μg/mg and 0.53±0.07 μg/mg Lentinan-like β-D-glucan. Button Mushroom, Shiitake Mushroom, and Oyster Mushroom showed the presence of Lentinan-like β-D-glucan at 16.16±4.15 μg/mg, 0.22±0.04, and 0.10±0.01 μg/mg, respectively.

Percent Recovery

A study was conducted on some factors affecting the colorimetric determination of B using the azomethine-H reagent on soils from Prince Edward Island. Two fine sandy loam soils (A and B) were used for the main study and additional soil samples varying in organic matter (OM) were used to assess the role of OM. Soils containing less than 3.0% OM and 3.1–4.1% OM required 0.4 g and 0.8 g charcoal per 25 g soil, respectively, to produce clear hot-water extracts. Quantities of greater than 0.8 g charcoal were necessary to produce clear extracts from soils containing more than 4.1% OM. Colored hot-water extracts of soil resulted in higher absorbance than those hot-water extracts treated with charcoal as measured at 430 mμ. Additions of 0.8 and 1.6 g charcoal or greater to the soils (A and B) resulted in considerably lower recoveries of B as noted by comparing the absorbance obtained using 0.4 and 0.8 g, respectively. Storage of azomethine-H up to 7 days did not affect the absorbance of the B-azomethine-H complex. One hour after the addition of azomethine-H, a maximum absorbance was found which persisted for up to 4 h. The percent recovery of B added to the two soils was about 10–12% less using azomethine-H as compared to those obtained using the carmine method. However, the mean hot-water-soluble B contents of 10 soils as measured using the carmine and azomethine-H reagents were 0.70 and 0.66 ppm. Pure B solutions when boiled with charcoal resulted in losses of B added. Such losses of B increased with increasing rates of charcoal.

Glossogyne Tenuifolia

Glossogyne tenuifolia (Labill) Cass. (Compositae) is a special medicinal plant in the Pescadores Islands. Ethanolic, cold and hot water extracts were prepared from the dried herb and their antioxidant properties and components were studied. Ascorbic acid, α-tocopherol, butylated hydroxyanisole, citric and ethylenediaminetetraacetic acids were used in assays for comparison. With regard to EC50 values in antioxidant activity, ethanolic and hot water extracts (0.08 and 0.09 mg/ml) were much more effective than the cold water extract (0.76 mg/ml). At 1.0 mg/ml, reducing capacities were 1.57, 0.31 and 1.04 for ethanolic, cold water and hot water extracts, respectively. Scavenging abilities on 1,1-diphenyl-2-picrylhydrazyl radicals were in descending order: ethanolic > cold water > hot water extracts. At 20 mg/ml, the hot water extract chelated all hydroxyl ions (100%) whereas the scavenging ability of the cold water extract was 68.86%. Chelating abilities on ferrous ions were in descending order: cold water > hot water > ethanolic extracts. Phenols were found to be the major antioxidant components. All EC50 values were below 20 mg/ml, and some even below 0.1 mg/ml, indicating that all three extracts from G. tenuifolia were rich in antioxidant properties.
