The study presents the latest scientific accomplishments in selection of silage hybrids with a special regard to digestibility as a quality parameter of the maize plant. The most important quality parameters, necessary in silage maize hybrid selection with the aim of completely defining their nutritive values, are presented in the case of the most demanded MRI hybrids of all maturity groups and encompass the following: the whole plant DM yield, the share of ears in DM yield, NDF, ADF and ADL content, and especially in vitro DM digestibility according to the Tilley and Terry method. Hybrids can be compared by the use of the exact values for the stated criteria and at the same time it is possible to make actual recommendations for certain production. The importance of the whole maize plant silage is manifested in beef cattle feeding, as the use of 3-12 kg silage day-1 with the appropriate feed concentrate significantly contributes to the more economic production of beef for which the demand in our country is realistic.

Abstract Background and study aims Post-colonoscopy colorectal cancer (PCCRC) is an important quality parameter of colonoscopy. Most studies have shown that the risk for colorectal cancer is reduced after an index colonoscopy for screening or diagnostic purposes with or without polypectomy. In this study, we aimed to quantify and describe PCCRC in Belgium, including the possible relationships with patient, physician, and colonoscopy characteristics. Patients and methods Reimbursement data on colorectal related medical procedures from the Intermutualistic Agency (IMA-AIM) were linked with data on clinical and pathological staging of colorectal cancer (CRC) available at the Belgian Cancer Registry (BCR) over a period covering 9 years (2002 – 2010). Results In total, 63 518 colorectal cancers were identified in 61 616 patients between 2002 and 2010. We calculated a mean PCCRC rate of 7.6 %. PCCRC was significantly higher in older people and correlated significantly with polyp detection rate and the number of resections and procedures performed per year per physician. Conditional observed survival, given still alive 3 years since first colonoscopy, for PCCRC was worse than for CRC. Older patients and patients with invasive carcinomas had a worse outcome. Conclusions Although no quality register exists in Belgium, we were able to demonstrate that PCCRC in Belgium is directly related to the experience of the physician performing the procedure. In the absence of a quality register, utilization of population-based data sources proved to be a valuable tool to identify quality parameters.

In Vitro Performance

Currently, a wide variety of complex non-oral dosage forms are entering the global healthcare market. Although many assays have been described in recent research, harmonized procedures and standards for testing their in vitro performance remain widely unexplored. Among others, dialysis-based techniques such as the Pharma Test Dispersion Releaser are developed for testing the release of drugs from nanoparticles, liposomes, or extracellular vesicle preparations. Here, we provide advanced strategies and practical advice for the development and validation of dialysis-based techniques, including documentation, analysis, and interpretation of the raw data. For this purpose, key parameters of the release assay, including the hydrodynamics in the device at different stirring rates, the selectivity for particles and molecules, as well as the effect of excipients on drug permeation were investigated. At the highest stirring rate, a more than twofold increase in the membrane permeation rate (from 0.99 × 10−3 to 2.17 × 10−3 cm2/h) was observed. Additionally, we designed a novel computer model to identify important quality parameters of the dialysis experiment and to calculate error-corrected release profiles. Two hydrophilic creams of diclofenac, Voltaren® Emulgel, and Olfen® gel, were tested and provide first-hand evidence of the robustness of the assay in the presence of semisolid dosage forms.

The prediction of quality parameters by near infrared reflectance analysis (NIRA) in whole-plant corn (Zea mays L.) was studied. Quality parameters included percent protein and in vitro dry matter digestibility (IVDMD). Calibrations were developed using two types of NIRA instruments: (a) a Neotec 51A, a six-tilting-filters type instrument and (b) a Technicon InfraAlyzer 400R, a 19-fixed-filters type instrument. Plant samples were collected from four locations across Ontario (Brucefield, London, Guelph and Elora). Forty samples were used in the calibration sets (C) for each quality parameter and for each instrument. A second group of samples, a prediction set (P) consisting of 200 samples, was used to validate the calibration equations. Regression analysis between NIRA predicted and IVDMD, indicated that this parameter was well predicted in both C and P sets and with the two instruments. Coefficients of determination (r2) for C and P sets were 0.91 and 0.85 for the InfraAlyzer 400R and 0.92, and 0.81 for the Neotec 51A, respectively. A standard error of the estimate (SEE) of 1.70 was observed for the prediction of IVDMD in both C and P sets with the InfraAlyzer 400R. Values of SEE for IVDMD using the Neotec 51A were 1.76 and 1.73 for C and P sets, respectively. NIRA predictions of percent protein showed differences between instruments. The r2 for C and P sets were 0.95 and 0.81 for the InfraAlyzer 400R and 0.90 and 0.58 for the Neotec 51A, respectively. The low r2 value for percent protein in the P set might be related to the mathematical treatment of the reflectance data chosen for the analysis. The SEE for the prediction of percent protein varied between 0.25 and 0.56.Key words: Corn (whole-plant), quality, infrared reflectance

Forage harvest belongs to the principal works in contemporary agriculture. Increasingly popular technology is the making round bales. The basic advantage of round balers is application versatility. Harvest method is useful for making hay, straw and haylage, Quality of the bale is dependent on the level of work equipment and operator. This paper is focused on comparing the round baler with variable bale chamber. Round baler Vicon RV 1601 OC14 was compared with round baller Welger RP 435 Master. Both models were equipped with variable chamber. The variable chamber was formed by the endless belts. The evaluation was conducted from quality of work perspective and efficiency. The most important quality parameter was the density of bales. Quality parameters of bales were determined by measuring and weighing. Straw bales and haylage bales were used for studies. Qualitative indicators were converted into dry matter content. Microwave drying according to Swedish University of Agricultural Sciences was used to determine the dry matter. Baler Welger reached better qualitative parameters of work. It was also demonstrated by statistical evaluation using Tukey test. It has clearly demonstrated that round baller Welger achieves significantly greater pressing than round baller Vicon. Greater difference was measured at baling straw. Difference was below the threshold of statistical significance during haylage baling. This difference shows favour of the round baller Welger. On the other hand baler Vicon requires lower input power.

AbstractSteel is currently main structural material in the world. Pig iron, which is the basic product of blast furnace process, is the semi-product used in steel-making processes. It is an alloy of iron with carbon containing above 2% C and other elements with limited content, intended for further processing. Chemical composition of pig iron is its basic quality factor, it defines its class and meeting requirements set by steel plant department. It is important that this chemical composition is as stable as possible. In addition, the temperature of pig iron is also very important quality parameter. The paper presents statistical analysis of quality parameters of pig iron produced in one of Polish steelworks. The content of alloying elements and temperature of tapping of pig iron from blast furnace were examined. The amount of non-conforming production and the losses related to the low quality were assessed.

Objective.This research aimed to evaluate the inclusion of Cucurbita foetidissima (BG) leaves as a partial or total substitution of alfalfa hay (AH) in beef cattle diets on in vitro methane output, gas kinetics and volatile fatty acids production. Materials and Methods.Five experimental treatments were formulated with the inclusion of BG as alfalfa hay (AH) substitute at 0, 25, 50, 75 and 100% in experimental treatments denominated CON (control), BG25, BG50, BG75 and BG100, respectively. Results.Lignin and organic matter decreased with BG inclusion (p<0.05). However, NDF, CT and TPC increased with higher levels of BG (p<0.05). Maximum gas production diminished with BG inclusion (p<0.05); whereas, microbial protein production, specific gas production rate and latency period were not affected (p>0.05). Methane production decreased linearly with BG inclusion (p<0.05). Nevertheless, CO2 production showed no changes with inclusion of graded levels of BG in the experimental treatments (p>0.05). Additionally, acetate and butyrate were not affected by BG inclusion (p>0.05); although, propionate increased linearly among treatments (p<0.05). Furthermore, inclusion of 75% of BG reduced 31% in vitro methane production without changes in CO2 production, suggesting an inhibition of endogenous methanogenesis. Conclusions.These results promote the inclusion of BG leaves as a potential and environmentally friendly forage source for beef cattle feeding.

Antioxidant activity and quality parameters of skin-on apple wedges from 10 cultivars were examined during chill storage and over two growing seasons. Storage of fresh-cut apple wedges had a significant impact on quality parameter indices such as browning index (p < 0.001) and texture firmness (p < 0.001). Headspace gas analysis indicated that the degree of browning negatively correlated to oxygen (-0.69) and positively (0.70) correlated to carbon dioxide levels. Antioxidant capacity as assessed by three in vitro methods (DPPH, FRAP and ORAC) decreased significantly for 9 of the 10 cultivars after 5 days of storage at 3 ± 1 °C (p < 0.001). These indices increased in case of Shampion apples over the same storage period for all three assays. With regard to antioxidant capacity and quality parameters, the cultivars Gloster, Alwa, Idared and Jonica were the best performing overall and could therefore be recommended as a core ingredient in fresh-cut fruit products.

Background: In automated glucose clamp experiments, blood glucose (BG) concentrations are kept close to a predefined target level using variable glucose infusion rates (GIRs) determined by implemented algorithms. Clamp quality (ie, the ability to keep BG close to target) highly depends on the quality of these algorithms. We developed a new Clamp algorithm based on the proportional-integral-derivative (PID) approach and compared clamp quality between this and the established Biostator (BS) algorithm. Methods: In numerical simulations, the PID-based algorithm was optimized in silico. The optimized Clamp-PID algorithm was tested in in vitro experiments and finally validated in vivo in a small ( n = 5) clinical study. Results: In silico, in vitro, and in vivo experiments showed better clamp quality for the new Clamp-PID algorithm compared with the BS algorithm: precision and absolute control deviation (ACD) decreased from 3.7% to 1.1% and from 2.9 mg/dL to 0.6 mg/dL, respectively, in the numerical simulation. The in vitro validation demonstrated reductions in precision (from 3.3% ± 0.1% (mean ± SD) to 1.4% ± 0.4%) and in ACD (from 2.3 mg/dL ± 0.4 mg/dL to 0.8 mg/dL ± 0.2 mg/dL), respectively. In the clinical study, precision and ACD improved from 6.5% ± 1.3% to 4.0% ± 1.1% and from 3.6 mg/dL ± 0.9 mg/dL to 2.2 mg/dl ± 0.6 mg/dl, respectively. The quality parameter utility did not change. Conclusions: The new Clamp-PID algorithm improves the clamp quality parameters precision and ACD versus the BS algorithm.
