THE EFFECT OF GROWTH REGULATOR ON STRUCTURAL AND NON-STRUCTURAL CARBOHYDRATES AND LIGNIN CONTENT IN SELECTED GRASS SPECIES AND CULTIVARS

The research was undertaken to determine the effect of the biostimulant Kelpak SL, derived from brown seaweed species Ecklonia maxima (kelp), on structural and nonstructural carbohydrates, as well as lignin content in orchard grass and Braun’s festulolium. The experiment was a split-plot arrangement with three replicates. It was set up at the experimental facility of the University of Natural Sciences and Humanities, Siedlce, in late April 2009. The following factors were examined: an application of the plant growth regulator Kelpak SL applied at the rate of 2 dm3·ha-1 vs an untreated control (0 dm3·ha-1), pure sown grass species and cultivars grown in monoculture: Dactylis glomerata, cv. Amila and Tukan, as well as Festulolium braunii cv. Felopa and Agula. This study revealed that an application of Kelpak significantly reduced cellulose, hemicellulose and lignin contents of the grasses but significantly increased non-structural carbohydrates, regardless of the remaining factors. Non-structural carbohydrates were the highest in Kelpak-treated Festulolium braunii (on average, 232.7 g·kg-1).

Initiating Data Management Instruction to Graduate Students at the University of Houston Using the New England Collaborative Data Management Curriculum

The need for graduate-level instruction on data management best practices across disciplines is a theme that has emerged from two campus-wide data management needs assessments that have been conducted at the University of Houston (UH) Libraries since 2010. Graduate students are assigned numerous data management responsibilities over the course of their academic careers, but rarely receive formal training in this area. To address this need, the UH Libraries offered a workshop entitled Research Data Management 101 in April, 2014, and all graduate and professional students on campus were invited to attend. The New England Collaborative Data Management Curriculum (NECDMC) served as the basis for the workshop, and two general sessions were planned. A research group in the College of Natural Sciences & Mathematics requested a special session after advertisements for the workshop were distributed. 105 individuals registered for the event, 65 signed into the workshop, and 63 completed the end-ofworkshop assessment. The results from this assessment, general lessons learned, and plans for future sessions will be discussed.

The effects of progressive low to high intensity exercise training on blood lipids and lipoprotein profiles in collegiate adolescents

The purpose of this study was to examine the effects of progressive low to high intensity exercise training on blood lipids and lipoprotein profiles in collegiate adolescents. Twenty (20) male and female adolescents who were volunteer to participate in physical exercise program and who were studying in Jimma University College of natural science were taken as a subject. The selected subjects were evaluated the baseline blood lipids and lipoprotein profiles before starting exercise training. Registered laboratory technicians were collect a sample of 5 mL fasting venous blood from each subject just before beginning the exercise, the second and the third blood tests were performed after the 4 th and 8 th weeks exercise training programs respectively. The subjects assigned to an individualized training program that consisted of walking, jogging and running progressively from low to high intensity. During 8 weeks the program included three training sessions per week. Descriptive statistics were produced for each of the parameters. Paired sample T-tests was performed, to find out the significant difference in selected lipid and lipoprotein profile. The significance level was set at P< 0.05 for each of the statistical tests performed. The SPSS 20 software was used for the statistical analysis. The mean TC difference of male and female subjects was 39.160 mmol/L (26.61%) and 50.260 mmol/L (29.63%) respectively after exercise training. The mean TG difference of male and female subjects was 20.660 mmol/L (19.31%) and by 23.020 mmol/L (18.68%) respectively after exercise training. The mean HDL difference of male and female subjects was 28.630 mmol/L (58.29%) and 24.320 mmol/L (52.04%) respectively after exercise training. And the mean LDL difference of male and female subjects was 33.080 mmol/L (31.03%) and by 48.210 mmol/L (36.58%) respectively after exercise training. Both male and female subjects showed that a significant increment in HDL and significant decrements showed in TC and LDL but not in TG. This study showed that exercise in female subjects reduce better TC, TG and LDL level than male subjects and male subjects develop better HDL level than female subjects. To be more beneficial in blood lipids and lipoprotein changes adolescents should participate in progressive low to high intensity exercise training programs additional to their daily routine.

CONTENT AND UPTAKE OF SELECTED TRACE ELEMENTS BY WEEDS IN POTATO TO CULTIVATION UNDER DIFFERENT CONDITIONS OF SOIL TILLAGE AND WEED CONTROL METHODS

The study utilized data from a field experiment carried out at the Experimental Station in Zawady owned by the University of Natural Sciences and Humanities in Siedlce in the years 2005–2007. The experimental factors included two soil tillage systems and seven weed control methods in potato. Iron, copper and zinc in weeds were determined with the AAS method. The trace element content in weed dry matter before row closure of potato depended significantly on soil tillage methods (excluding Cu), weed control methods and weather conditions, and, prior to tuber harvest, on soil tillage and weather conditions during the growing season. The uptake of Fe, Cu, and Zn by weeds from the area of 1 hectare depended on the experimental factors, weed biomass and weed chemical composition.

Effect of foliar fertilization with tytanit on the content of selected macroelements and sodium in celery

AbstractFoliar application of growth regulators or fertilizers containing biostimulators can influen-ce the uptake and accumulation of mineral elements by plants. A pot experiment carried out in two annual series (year of experiment I and II) examined the effect of various concentrations of Tytanit applied once or twice against mineral fertilization (NPK), in comparison with the control object (without fertilization) and the object with mineral fertilization (NPK), on the total content of potassium, calcium, magnesium and sodium in petioles and leaf blades of celery. The experi-ment involved the application of various concentrations of Tytanit, ranging from 0.001% to 3.6%. The content of selected elements in the plant material was determined after dry mineralization, using the ICP – AES method. The total content of potassium in petioles of celery fertilized with NPK + 3.6% was higher or the same as in the control and in plants fertilized with NPK (I and II series). The results were similar in the case of leaf blades (except for series I). The highest concentration of Tytanit (3.6%) resulted in a reduction of the total calcium content in both of the tested parts of celery and magnesium in petioles, compared with the control. On the other hand, the total content of sodium increased along with the growth of the fertilizer concentration. The highest bioaccumulation of calcium was observed in celery cultivated in the object without ferti-lization (control). A significantly higher potassium content (mean from both series of research) and over two-fold higher content of calcium were found in celery leaf blades than in petioles, while a higher content of magnesium and sodium appeared in petioles than in leaf blades. The values of (K+Na) : (Ca+Mg) ratios in leaf blades were found to be over two-fold higher than in petioles of celery fertilized with Tytanit.Key words: petioles and leaf blades of celery, Tytanit concentration, potassium, calcium, mag-nesium, sodium.prof. dr hab.

The Effect of Potato Ridge Height and Harvest Date on Tuber Injuries

Abstract A potato experiment was conducted from 2004 to 2006 at the Zawady Experimental Farm. The farm is part of the University of Natural Sciences and Humanities in Siedlce, Poland. Tuber infection and injury by diseases and pathogens of three potato cultivars were assessed according to the potato ridge height and harvest date. The weight of mechanically injured tubers was also determined depending on the potato ridge height and harvest date. The weight of potato tubers infected by fungal and bacterial diseases was influenced by the cultivar, growing season, harvest date, and ridge height. Potatoes grown to their standard height and height ridges, were significantly less infected by diseases at the first harvest date. The weight of tubers in which the tubers were injured by soil pests, was affected by the cultivar and ridge height. Potatoes cultivated in a ridge which was 20 cm high, had tubers with significantly less mechanical injuries compared with a low (16 cm) ridge and high (24 cm) ridge.

Reuse of Controls in Nested Case-Control Studies

To the Editor: A nested case-control design with risk set sampling1,2 matches controls to cases on time and often on additional factors. This matching has been thought to make the controls unusable for other endpoints. However, recent methods3–5 enable the reuse of controls, thereby improving efficiency. We demonstrate this in an example assuming proportional hazards models for time-to-event and estimating hazard ratios (HRs). We consider inverse probability–weighted Cox regression models weighted by 1.0 divided by the probability of ever being sampled as control. Subjects can be sampled at each event time they are at risk and meet the matching criteria, thus typically at several occasions. We estimate these probabilities using two methods. For the Kaplan-Meier method,3,4 note that the probability of ever being sampled is 1.0 minus the probability of never being sampled, and the latter probability is the product of probabilities of not being sampled at each possible event time. This leads to the formula which is similar to the Kaplan-Meier estimator for the sampling probabilities . The and are numbers of possible and sampled controls for the case at time , respectively. The is an indicator function that is either 0 or 1. For the second method,5,6 referred to as generalized linear model weights, we consider indicators of ever being sampled as controls among all noncases. The sampling probabilities are estimated using logistic regression with entry time , censoring time , and matching variables as covariates, See the eAppendix (https://links.lww.com/EDE/A762) for more details. We applied inverse probability weighting in a study of serum 25-hydroxyvitamin D (s-25(OH)D) and prostate cancer7 to evaluate this method. The cohort consisted of participants in health surveys in Norway, comprising 116,493 men. Among those, 2,118 were diagnosed with prostate cancer during follow-up. For each incident case, one control was sampled from the case’s risk set, matched on age at serum sampling ±6 months, date of serum sampling ±2 months, and county of residence. Meyer et al7 focused on the association between s-25(OH)D and incidence of prostate cancer. Due to the increased practice of screening for this cancer, death from prostate cancer might be a better endpoint when considering the most serious cases. Among the incident cases, 367 men died from prostate cancer. Traditional analysis of nested case-control data can use only the controls for incident cases who also died from prostate cancer, whereas all sampled controls can be used with inverse probability–weighted analysis. Robust variance estimation, possibly slightly conservative,6 was chosen for the present analyses. The Table displays results from traditional analyses and inverse probability–weighted analyses with Kaplan-Meier and generalized linear model weights. For both endpoints, the hazard rates from inverse probability weighting and traditional analyses were approximately equal. The inverse probability–weighted standard errors for the incidence endpoint were somewhat smaller than the standard error from the traditional analysis. In contrast, the inverse probability–weighted standard errors for the death endpoint were considerably smaller. Because all available controls could be used, the efficiency increases.TABLE: Comparison of the Traditional Estimation Method and Inverse Probability WeightingWe also analyzed a physical activity variable available in the complete cohort (n = 116,493) to contrast cohort and nested case-control analyses. The endpoint was incidence of prostate cancer. With cohort data, the HR was 1.07 (95% confidence interval = 0.95–1.22) compared with 1.09 (0.92–1.29) using traditional nested case-control analysis and 1.07 (0.90–1.26) and 1.01 (0.85–1.21) with generalized linear models and Kaplan-Meier weights, respectively, when comparing moderate activity to sedentary. Hence, the traditional estimates are not necessarily closer to cohort estimates than inverse probability–weighted estimates (see eAppendix [http://links.lww.com/EDE/A762] for full analysis). Our experience suggests that Kaplan-Meier and generalized linear model weights have similar performance with comparable estimated HRs and variances. However, with extremely close matching, simulations indicates that biased estimates can occur when applying Kaplan-Meier weights.8 We have demonstrated that inverse probability weighting can be a powerful alternative with sub-endpoints. Moreover, reuse of controls can be helpful in many multiple outcomes settings. The eAppendix (https://links.lww.com/EDE/A762) gives an example of inverse probability weighting for specific metastasis groups.

Phytochemical, Nutrient Composition and Serum Lipid Lowering Effect of Xylopia aethiopica Fruit

Aims: The present study was carried out to evaluate the effects of Xylopia aethiopica on serum lipids in fed rats. Also the quantitative phytochemical and nutrient composition was investigated. Study Design: Quantitative phytochemical, proximate analysis and in vivo effect on serum lipid profile. Place and Duration of Study: Department of Biochemistry, College of Natural Sciences, Michael Okpara University of Agriculture, Umudike Abia State, between June 2013 and September 2013. Methodology: The fruit were cut into small piece, dried and ground into powder. The quantitative phytochemical and proximate nutrient analyses of the powder sample were determined using standard methods. The serum lipid lowering effects of the powdered fruit in rats was determined by feeding different groups of rats with graded levels (5, 10, 20 and 50%) of the powdered fruit incorporated in their feed for 21 consecutive days and the effects on the total cholesterol, triglyceride, LDL-C, and HDL-C were compared with a negative control. Results: The fruit sample produced significant (p&lt;0.05) concentration-dependent decrease in the total serum cholesterol, triglyceride, LDL-C and VLDL-C levels and increase in serum HDL-C level in fed groups of rats when compared to the control group. The phytochemical analysis showed that the sample contained tannins (4.96%), flavonoids (0.81%), saponins (2.93%) and alkaloids (1.24%). The proximate analysis of the nutrient composition of powdered Xylopia aethiopica sample showed the presence of moisture, lipid, crude fibre, crude protein, ash and nitrogen free extracts in the following proportion 6.32, 12.54, 14.51, 0.91, 2.31 and 63.41% respectively. Conclusion: The fruit sample demonstrated good hypolipidemic effects which may suggest that the consumption of Xylopia aethiopica fruit may help in the reduction of the incidence of hyperlipidemia related diseases in patients.

The substance shows rich polymorphism. In addition to ferroelectric and antiferroelectric smectic C∗ phases it possesses three ferrielectric sub-phases. Phase transitions between the phases were revealed by di erential scanning calorimetry and static dielectric permittivity measurements. The aim of this paper was to study phase transitions and di erences in dielectric spectra shown by di erent phases. Collective and molecular dynamics of all phases shown by 10.OPOSMH will be discussed in terms of theoretical models. Dielectric spectra of antiferroelectric phase show two characteristic dielectric relaxation modes: one connected with the molecular process (reorientation around the short axis) and the other originating from uctuations of antiferroelectric order parameters.
