An investigation was undertaken to compare the relative magnitudes of the differential effects of environment (i.e., stations) and of malting methods on the malting quality of barley varieties. Samples of Olli, O.A.C. 21, Hannchen, and Regal from four stations were malted by eight methods representing the combinations of germinating at 50° and 56° F., at 42 and 46% moisture, and for six and nine days.Statistical analyses showed that, with respect to diastatic activity, wort nitrogen, and extract yield, the variations due to the differential effect of environment on varieties were greater than the variations due to the differential effect of malting methods on varieties. As a result of this study and earlier ones, it appears that the former effect is the limiting factor in studies of the comparative malting qualities of varieties. The latter effect is of less importance but must be kept in mind if errors in the interpretation of the results of routine tests are to be avoided. In general, it appears that if routine tests show that the mean values for any variety, when grown at 12 stations representing a reasonable range of environment, differ from the values for the standard variety by more than 1% in extract, or 10% in diastatic activity or wort nitrogen, a real difference exists between the varieties, which cannot be overcome by any reasonable change in malting conditions.

Source Of Error

Samples of eight barley varieties grown at six widely separated points in Canada were malted in duplicate under standard conditions in laboratory equipment. After six days in the germinator, half of each sample was removed and kilned. The remaining halves were grown two days longer before kilning. The relative positions of the varieties with respect to extract, diastatic power, and permanently soluble nitrogen, were changed by the additional two days' growth, but the changes were generally small by comparison with the spreads between varieties and the greater changes in their relative positions when grown at different stations, ft is concluded that the differential effect of malting method is an appreciable source of error in the interpretation of the results of routine malting tests, but that the limiting factor in studies of the comparative malting qualities of varieties is the differential effect of environment on them.

Diastatic Power

Samples of O.A.C. 21 and Wisconsin 38 barley from two stations were germinated at 56° and 50° F. with 44.5% moisture, and with 44.5 and 42.5% moisture at 53° F. Aliquots were kilned and analyzed after 3, 5, 7, 9, 11 and 13 days. Data for extract, diastatic power, and permanently soluble nitrogen, as percentage of wort solids, were plotted against time. Both varieties responded in almost exactly the same manner to changes in temperature and moisture. Values for O.A.C. 21 were consistently higher, but paired curves, representing samples of both varieties from the same station, became closer with increasing time, owing largely to overmodification of the O.A.C. 21. A real difference in malting quality between these two varieties, greater than the differential effect of malting method on them, is therefore indicated.

Proper peer review and quality of published articles are often regarded as signs of reliable scientific journals. The aim of this study was to compare whether the quality of statistical reporting and data presentation differs among articles published in ‘predatory dental journals’ and in other dental journals. We evaluated 50 articles published in ‘predatory open access (OA) journals’ and 100 clinical trials published in legitimate dental journals between 2019 and 2020. The quality of statistical reporting and data presentation of each paper was assessed on a scale from 0 (poor) to 10 (high). The mean (SD) quality score of the statistical reporting and data presentation was 2.5 (1.4) for the predatory OA journals, 4.8 (1.8) for the legitimate OA journals, and 5.6 (1.8) for the more visible dental journals. The mean values differed significantly (p < 0.001). The quality of statistical reporting of clinical studies published in predatory journals was found to be lower than in open access and highly cited journals. This difference in quality is a wake-up call to consume study results critically. Poor statistical reporting indicates wider general lower quality in publications where the authors and journals are less likely to be critiqued by peer review.

Background:Boolean remission criteria is one most popular and stringent criteria in treating patient with rheumatoid arthritis (RA), because it may guarantees a stable clinical course after attaining remission.Objectives:Impact of time span from initiation to achieving Boolean remission on maintaining disease activity, daily activities, and quality of life after attaining Boolean remission was investigated from daily clinical practice data.Methods:685 patients with RA since August 2010 under the T2T strategy were treated. They were monitored for their TJC, SJC, PGA, EGA, CRP, and disease activity indices such as CDAI, SDAI, DAS28, and Boolean criteria at every visit. HAQ-DI score, pain score using visual analog scale (PS-VAS), and EQ-5D were also monitored, and the quality of life score (QOLS) calculated from EQ-5D was determined at every visit from the time of diagnosis (baseline).Of 685 patients, 465 patients had achieved Boolean remission >1 times, and were consecutively followed up for >3 years. These patients were enrolled in the study. Time span from the first visit to first Boolean remission was calculated. The relationship between the time span and each of background parameters, and the relationship between the time span and each of the mean values of the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at the first Boolean remission and thereafter was evaluated statistically.Patients were subsequently divided into the G ≤ 6 and G > 6 groups based on the achievement of first Boolean remission within two groups: time span G ≤ 6 months and G > 6 months. The two groups were compared with regard to the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at first visit and at the time of first Boolean remission, and the mean values of these parameters after remission were evaluated statistically. Moreover, changes of these parameters and the mean Boolean remission rate after the first remission, and SDAI remission rate at the first Boolean remission to thereafter were compared between the two groups statistically.Results:Out of 465 patients, females comprised 343 (73.7%), and the mean age was 67.8 years (range, from 21–95 years). The mean disease duration at first visit was 6.1 years (range, from 1 months–45 years). The mean follow up length was 88.1 months (range: 36–122 months; median: 85 months) and mean time span from the first visit to the first Boolean remission was 8.1 months. The mean SDAI score, HAQ score, PS-VAS, and the QOLS at first visit were 13.3, 0.467, 33.2, and 0.834, respectively. Among the study parameters, PS-VAS and QOLS were significantly correlated with the time span. For parameters at the first Boolean remission, HAQ-DI score, PS-VAS, and QOLS demonstrated significant correlation with the time span, whereas SDAI, HAQ-DI score, PS-VAS, SHS, and QOLS after the Boolean remission demonstrated significant correlation with the time span.The comparison between the G ≤ 6 and the G > 6 groups revealed that the disease duration, HAQ score, and PS-VAS at baseline in the G > 6 were significantly higher than that in the G ≤ 6 group, and QOLS in the G ≤ 6 group was significantly higher than that in the G > 6 group at baseline. Similarly, the HAQ score and PS-VAS at the first Boolean remission in the G > 6 group were significantly higher than that in the G ≤ 6 group, whereas QOLS in the G ≤ 6 group demonstrated no significant difference compared with that in the G > 6 group.The mean value of the SDAI score after the first Boolean remission in the G > 6 group was significantly higher than that in the G ≤ 6 group. Similarly, the SDAI score, HAQ score, and PS-VAS after the first Boolean remission in the G > 6 group were also significantly higher than those in the G ≤ 6 group, and the mean value of the QOLS in the G ≤ 6 group were significantly higher than that in the G > 6 group. The Boolean remission rate and SDAI remission rate after the first Boolean remission were significantly higher in the G ≤ 6 group than those in the G > 6 group.Conclusion:Attaining Boolean remission ≤ 6 months for RA has significant benefit for more stable disease control, that leads good maintenance of ADL.Disclosure of Interests:None declared

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.

At the moment the suitability of stored red blood cells (sRBC) for transfusion is checked by routine methods such as haemoglobin estimation and the level of haemolysis. These methods cannot characterize directly the quality of the membranes of sRBC. The aim of this work is to assess the quality of sRBC based on such criteria as the membrane’s stiffness and the size and the form of sRBC. Materials and Methods. We have investigated 5 series of dry cytosmears of the sRBC which had been kept in blood bank in a period from 1 to 35 days. After AFM imaging, in every specimen, 5 RBC were chosen at random; the diameter, the height, and the stiffness were measured on each of them. Results. The present study shows high increase of the mean values of YM and height of RBC after 35 days of storage and decrease of the mean values of their diameter. Conclusion. Statistically significant high increase of the mean values of YM indicates the decrease of the elasticity of the cells in the course of storing of the RBC. This parameter along with the morphological characteristics can be used as criterion for assessment of applicability of the sRBC for blood transfusion.

<strong>Introduction:</strong> The satisfaction level with health care reflects the quality of care from the patient’s perspective. The aim of this study is to assess patient satisfaction with anesthesia care in a Portuguese general hospital by using the “The Heidelberg Peri-anaesthetic Questionnaire”.<br /><strong>Material and Methods:</strong> The questionnaire was translated and tested based on psychometric quality criteria in a sample of 107 patients who underwent elective surgery as inpatients at Hospital de São João. The global satisfaction and for each dimension of care were calculated. We analyzed the differences between patients with different levels of satisfaction, identifying potential confounding factors.<br /><strong>Results:</strong> The Portuguese version of the questionnaire has 32 items distributed in three dimensions: ‘staff’, ‘discomfort’ and ‘fear’. The mean values of satisfaction for each dimension were 83.4%, 66.8% and 65.9%, respectively. The internal consistence was demonstrated by a Cronbach’s alpha coefficient ranging from 0.776 to 0.875 in the three dimensions. Satisfied and dissatisfied patients differed in the three dimensions, but to a lesser degree in ‘staff’. In the multivariate analysis we found significant influence of gender in the ‘discomfort’ dimension.<br /><strong>Discussion: </strong>The questionnaire has good psychometric characteristics. The domain ‘staff’ includes three domains of the source questionnaire.<br /><strong>Conclusions:</strong> Its application revealed high satisfaction levels regarding the staff. Dissatisfaction was mainly seen in the “fear” and “discomfort” dimensions, the latter being significantly lower in males.

ABSTRACT The market demand for tropical fruits has been growing steadily over the past two decades and global papaya production has grown significantly over the last few years. This sector, however, suffers greatly from postharvest losses due to reduced quantity and quality of fruits between harvest and consumption. The use of ethylene inhibitors after harvest could improve the final quality of the fruit to satisfy the consumer and also minimize waste. The physiological and biochemical responses of ‘Solo’ papayas treated with the ethylene inhibitor 1-methylcyclopropene (1-MCP) to extend storage shelf life and maintain quality during long-term storage are deeply discussed in this study. Papaya fruits arrived at Cranfield University (CU) and received a 24 h 1-MCP, being stored at 20 ºC for 10 days. The ethylene inhibitor 1-MCP application significantly delayed ‘Solo’ papaya ripeness on fruit storage by reducing respiration rate and ethylene production. There was a delay from 7 days in fruit firmness loss and the retention of green peel colour was increased. Inhibition of ethylene perception by 1-MCP did not prevent the accumulation of sugars and the mean values were similar and higher than those found for control fruits, which are possibly due to the lower reaction speed, leading to a higher accumulation.

The anthropometric reference data used to examine the growth pattern of children in Spain are obtained from studies carried out several years ago. In the region of Extremadura, the tables obtained by the Faustino Obergozo Foundation, which date back to 2004, are used. The first objective of this work is to develop growth tables and graphs that accurately reflect the somatometric variables of children in Extremadura. Secondly, the averages of these variables by sex will be compared to determine if there are significant differences between them. A database provided by the General Directorate of Planning, Training, and Health and Social Quality of the Regional Government of Extremadura was used, which contains the measurements of height, weight, and body mass index (BMI) of boys and girls in Extremadura between the years 2006–2016. The database was analyzed using the Statistical Package for the Social Sciences (SPSS) version 23 and the R software version 3.5.1, considering a cross-sectional study. As a result, the tables and growth graphs of Extremadura’s population base for weight and height are presented, from birth to 10 years, as well as comparisons of the average values of the analyzed variables between boys and girls. We found that there are significant differences in the mean values, according to sex, of the height and weight. On the other hand, BMI progressed normally when comparing the results of the Extremadura population with those reflected by the World Health Organization (WHO). Differences were found when comparing the results with those obtained by the Faustino Orbegozo Foundation.

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.
