Abstract The dried sclerotium of the fungus Wolfiporia cocos is edible and has medicinal value. This study aimed to understand the accumulation of radioactivity arising from the alpha 210Po, and beta-emitting 210Pb, in the sclerotium’s shell and core and assess a potential effective dose for consumers. Sclerotia were collected in the wild and from cultivars in China’s Anhui and Yunnan provinces. The mean values of 210Po activity concentration levels were 0.36 Bq kg−1 dry weight in the core and 12.0 Bq kg−1 dw in the shell; 210Pb activities were 0.43 and 9.84 Bq kg−1 dw, respectively. The potential effective radiation doses from core layers (as a major raw material of the sclerotium) ranged from 0.13 to 3.43 µSv kg−1 dw from 210Po decay and from 0.11 to 1.52 µSv kg−1 dw from 210Pb decay. Corresponding values for shell ranged from 0.80 to 42.4 for 210Po and from 0.53 to 13.6 µSv kg−1 dw for 210Pb. In general, the intake of W. cocos sclerotia varies between consumers, but this would not significantly change the effective radiation doses from 210Po and 210Pb isotopes. The consumption thus appears to be safe from a radiological protection point of view. Graphical abstract

ABSTRACT: Crambe is a rapeseed with high oil content and can be used as a winter cover or as a source of raw material for the production of biodiesel, however espite the growing interest in the culture, research on the subject is still incipient, especially concerning the seed production and analysis technology. The purpose of this study is to evaluate the physiological quality of crambe seeds, 'FMS Brilhante' cultivar, by testing the pH of exudate. Five seed lots were submitted to the determination of water content and the tests of germination and vigor (first count, emergence and tetrazolium). In the conduction of pH exudate test, temperatures (25 and 30oC), and periods of seed imbibition in water (15, 30 and 45 minutes) were tested. The experiment was conducted in a completely randomized manner, with four replicates, and the mean values were compared by the Tukey test at 5% probability; Pearson correlation between the pH of the exudate and initial tests was also made. Testing the pH of exudate is promising for separating lots of crambe seeds and the following combinations of 25°C/30 minutes or 30°C/45 minutes can be used.

The aim of the study was to synthesize the latest literature data on the content of toxic elements in tissues of hunted animals and to determine whether there is a health risk associated with consumption of these products in the light of current legal regulations. The data show the increased mean lead contents in kidneys of wild boar (1.1900 mg/kg) and roe deer (0.9060 mg/kg) and in the muscle tissue of wild boar, roe deer and deer; the contents are even up to 0.1240 mg/kg, 0.1760 mg/kg and 0.2200 mg/kg, respectively. In addition, the increased mean cadmium content indicates the possibility of the deposition of this element in muscle tissue of wild boars (0.0519 mg/kg) and deer (0.1000 mg/kg), as well as in the liver of wild boars (5.5730 mg/kg) and roe deer (6.4350 mg/kg) and in kidneys of game species, sometimes far above the applicable maximum levels. The highest mean cadmium contents in kidneys of wild boar, roe deer and deer are 49.5000 mg/kg, 80.2600 mg/kg and 4.9740 mg/kg, respectively. The mean values of the amount of arsenic do not usually exceed the legally established maximum levels of this element. Only the borderline value of arsenic in muscle tissue of roe deer is slightly exceeded and amounts to 0.2700 mg/kg. There is the possibility of the accumulation of larger amounts of mercury mainly in kidneys of deer and roe deer. The highest mean content of this element of 0.1001 mg/kg is demonstrated in the kidneys of deer. The research on the content of toxic elements in meat of hunted animals indicates the need to regularly monitor the quality of the obtained raw material as well as to exclude selected tissues of wild animals from consumption.

ABSTRACT The use of organic fertilizers can increase the production of forest species for the extraction of wood from monoculture stands or integrated systems. This study aimed to evaluate the effect of applying doses of sheep manure on the biometric traits of Mimosa caesalpiniifolia (‘sabiá’) in a silviculture system in an area previously occupied by native degraded pasture in an Albaquult. The experimental design was randomized blocks with four repetitions, with treatments corresponding to five doses of sheep manure per plant: 0, 2, 4, 8, and 12 kg in the first year, while in the second year the double of the doses (0, 4, 8, 16 and 32 kg per plant) were applied as topdressing under the canopy. The following biometric variables were evaluated: height (H); root collar diameter (RCD); diameter at breast height (DBH); above-ground dry weight (AGDW); accumulation of nutrients (aerial part); and soil fertility. The plants were responsive to the organic fertilization regarding the variables H, DBH, and AGDW. The sheep manure increased the mean values of pH, P, K, Ca, Mg, SB, CEC, BS, S-SO4 2- and Zn, and reduced the potential acidity in the 0-0.20 m soil layer. The organic matter variable increased up to the dose of 13.70 kg per plant. The accumulation rates of macro and micronutrients in the ‘sabiá’ plants were N > Ca > K > Mg > P > S and Fe > Mn > B > Zn > Cu, respectively.

SummaryIntroduction. Dental implant therapy has become a popular method of replacing one or more missing teeth. Osseointegrated dental implants have been studied from histological, microbiologic and biomechanical point of view, but the neurophysiologic integration of the implants and the supported prostheses has received less attention. The sensory mechanism of dental implants is qualitatively different from that of natural teeth. Psychophysiological tests are used to determine the tactile sensibility perceived with the implants and teeth.Aim of the study. The purpose of this study was to compare tactile sensibility of natural teeth and osseointegrated dental implants.Material and methods. Forty-three patients were included in the study. Natural teeth were divided into two groups: non endodontically treated teeth (NETT) and endodontically treated teeth (ETT). Load tests were done by a computer-controlled pressure sensitive device („Power Lab“ Data Acquisition System - model 4/25T, sensor - model MLT003/D; ADInstruments), specially modified for intraoral use. Pushing forces were applied parallel to the vertical axis of teeth and implants. The patient held a signal button which he/she activated as soon as touch was sensed. At this moment the computer registered passive absolute tactile threshold - measured in Newtons. The mean values of passive absolute tactile threshold for natural teeth and dental implants were calculated. Comparison of the mean values was performed by the means of t-test.Results. Passive absolute tactile threshold for osseointegrated dental implants was 2.39 N (SD=1.92), and for teeth - 0.67 N (SD=0.72), for non endodontically treated teeth it was 0.63 N (SD=0.72) and for endodontically treated teeth - 0.73 N (SD=0.69). The differences in mean values were statistically significant (p<0,0001) except for mean values of NETT vs. ETT.Conclusion. This study shows that patients with osseointegrated implants subjectively feel “touch” sensation when greater force is applied compared with natural teeth.

Abstract Red lentils are a very important raw material in the food industry due to their high protein content and high level of health-promoting components. The nutritive value of red lentils is the most important attribute from a research point of view; it can be increased by germination, soaking as well as physical and biochemical processes. The antinutritive materials are reduced or denatured by the germination process and indigestible components become available to the human body. Heat treatment was applied to achieve different temperatures and increase the microbiological stability of germinating samples. The effect of heat treatment on the amounts of certain components and the activity of oxidative enzymes was tested during our experiments; the nutritional characteristics (water-soluble total polyphenol content (WSTPC), water-soluble protein content (WSPC), water-soluble antioxidant capacity, in addition to peroxidase and polyphenol oxidase enzyme activities) of different treatments in red lentil samples were monitored. The WSTPC in our samples ranged from 0.726 mg Gallic Acid Equivalent GAE/g DW (DW being dry weight) to 1.089 mg GAE/g DW, and the WSPC varied from 19.078 g / 100g DW to 29.692 g / 100 g DW. Results showed that germination led to an increase in the WSTPC and WSPC. The peroxidase enzyme activity also exhibited an increase during germination which could result in deepening of the colour of the finished products. Germination resulted in the water-soluble antioxidant capacity of red lentil samples decreasing.

This research was carried out in the climate chamber in order to determine the effect of hydrosols obtained from sage grown with selenium application on germination of fenugreek and coriander seeds. Different concentrations of sage hydrosol (2.5, 5, 7.5 and 10 ml) and purified water used as control were applied to the fenugreek and coriander seeds. Germination rate, fresh weight, dry weight, root length, shoot length and root / shoot ratio of fenugreek and coriander seeds were applied. Variance analysis was performed according to the split plot design and the mean values were compared with LSD test. According to the results of the research; germination rate of fenugreek seeds 38.35-51.00%, fresh weight 0.04-0.12 g, dry weight 0.001-0.035 g, root length 0.71-2.02 cm, shoot length 1.27-3.20 cm, root/shoot ratio varied between 0.34-0.82, germination rate of coriander seeds 18.61-39.21%, fresh weight 0.0011-0.034 g, dry weight 0.004-0.030 g, root length 1.5-4.58 cm, shoot length 1.08-3.69 cm, root/shoot ratio 0.47-2.51 were found. The highest germination rate was obtained in 2.5 ml dose of sage hydrosol (51.00%) in fenugreek seeds and the highest germination rate was found in 7.5 ml dose of sage hydrosol (39.21%) in coriander seeds.

The present study aims to investigate radiation doses from Computed Tomography Pulmonary Angiography (CTPA) examinations based on the patient&rsquo;s size and to estimate the probability of cancer risk induced from the examination. Data from 100 patients who had undergone CTPA examinations, such as scanning acquisition parameters, patient demography, as well as radiation dose exposure, were collected and analysed. All subjects which aged above 18 y/o were scanned using a Philips Brilliance 128 multi-detector CT (MDCT) scanner. The mean dose value for Volume Computed Tomography Dose Index (CTDIvol), Dose-Length Product (DLP) and effective dose (E) were 11.06 &plusmn; 7.17 mGy, 400.38 &plusmn; 259.10 mGy.cm and 8.68 &plusmn; 5.47 mSv respectively. In addition, with respective of patient&rsquo;s effective diameter, the mean SSDE value for Group 1, Group 2 and Group 3 were 9.93 &plusmn; 3.89, 13.70 &plusmn; 9.04 and 22.29 &plusmn; 7.35, respectively. Cancer risk per million procedure was calculated based on te recommendation by the International Commission on Radiological Protection Publication 103 report. The organ dose and cancer risk attained for breast, lung and liver were 17.05 &plusmn; 10.40 mGy (194 per one million procedure), 17.55 &plusmn; 10.86 mGy (192 per one million procedure) and 15.04 &plusmn; 9.75 mGy (53 per one million procedure), respectively. In conclusion, CTDIvol underestimated, and SSDE was more accurate in describing the radiation dose. Lung and breast with larger lung effective diameter received the highest dose exposure which increase the probability of the cancer risk. Therefore, it is important to apply optimised protocols in order to reduce patient&rsquo;s exposure during CTPA examination.

AbstractWeather conditions prevailing in Poland often cause that meadow sward designated for silage is harvested too late, which decreases the quality of prepared silage. The aim of the research was to assess the quality of silages from dried meadow sward. The silages were ensiled in large cylindrical bales in selected individual farms specializing in milk production. The farms where the research was carried out were located in three voivodeships: slaskie, malopolskie and podkarpackie. In the prepared plant material, the basic chemical composition was determined using the method. When comparing the mean values, it was established that silages from the investigated region had a favourable content of total protein, the highest concentration was recorded for silages from Slask, followed by Malopolska and Podkarpacie. A slightly elevated concentration of crude fibre, fraction of acid detergent fibre (ADF) and neutral detergent fibre (NDF), was recorded. This fact shows that farmers collect raw material, particularly from the first cut, too late. Nutrient value of silages from meadow sward decreases with progressing vegetation. Higher protein and energy losses during sward ensiling were also observed at considerable drying of the plant material. In most cases, silages from the studied farms had a low content of monosaccharides. The carried out chemical analyses showed that in overall assessment the studied silages are of good quality; silages prepared from meadow sward from the third cut had the highest value. Proper technology of preservation of meadow sward is one of important factors in the production of feed for ruminants.

The purpose of this study was to compare surface hardness between titanium-nitride coated crowns (TiNCs) and stainless steel crowns (SSCs), and to evaluate the corrosion resistance and color sustainability of TiNCs. Ten TiNCs and 10 SSCs were used for the hardness test. Measurement was performed 30 times for each type of crowns, and the mean values were compared. Metallic raw material plates (before being processed into crowns) of TiNCs and SSCs were prepared for the corrosion resistance test. The total amounts of metal ion releases in the test solution were detected by inductively coupled plasma-optical emission spectrometry. Five TiNCs were subjected to the color sustainability test by applying repetitive brushing forces. The mean hardness values of TiNC group and SSC group were 395.53 ± 105.90 Hv and 278.70 ± 31.45 Hv respectively. Hardness of TiNCs were significantly higher than that of SSCs. The total amounts of metal ion releases from the materials of TiNCs and SSCs satisfied the criterion in International Organization for Standardization 22674. The results mean that TiNCs and SSCs were not harmful in an acidic environment. The golden coating was stable against the repetitive physical stimulations for a given period time.

Between- and within-population variation for 21 quantitative characters was estimated for five populations of Datura stramonium originating along a climatic gradient ranging from southern Ohio, U.S.A., to Elgin County, Ont., Canada. Datura stramonium is a predominantly inbreeding, annual species with a distribution which is expanding northward in Ontario. Plants were grown from seed to maturity in the greenhouse under uniform conditions. The five populations differed significantly in the mean values of all measured characters. Canonical variates analyses were used to distinguish the populations on the basis of combined groups of characters. Canonical means of the five populations differed significantly for both seedling and mature plant characters, but the relative distance between populations varied for the two character sets. Levels of between- and within-family variation differed significantly among populations and from one character to another. Percent germination, seedling dry weight, and leaf area were strongly correlated with initial seed weight. Seed weight and cotyledon length increased and days to anthesis decreased with a decreasing length of the growing season.
