Authors: Michałojć Zenia , Buczkowska Halina 
Published: August 2013

Abstract
Studies upon the ‛Epic F1’ eggplant were carried out in 2004 − 2005 in an unheated plastic tunnel. The eggplant was cultivated in cylinders made of rigid foil of 10 dm3 capacity each filled with horticultural peat in 0.6 × 0.5 m spacing. The experiment consisted of two factors in a complete randomized design. The influence of the following factors was examined: 1 - potassium fertilizer kind (KCl, K2SO4, KNO3); 2 - potassium dose (8, 16, 24 g K per plant). Fruit samples were harvested for laboratory analyses in the middle of August in the middle of the fruiting period. Fruits were harvested every 7-10 days at the stage of utilization maturity. Total and commercial yields as well as the number of fruits per 1 m2 were evaluated. Fresh fruits were subjected to the following analyses: dry matter - drying method, vitamin C - Tillmans’ method, and sugars - Schoorl-Rogenbogen’s method. The obtained results were subjected to analysis of variance. Different potassium fertilizers did not significantly influence yield size and structure as well as eggplant fruit number. The highest fruit yield was obtained from plants fertilized with potassium in the form of KCl at the largest dose of 24 g K per plant. No effects of potassium doses in a form of K2SO4 and KNO3 on eggplant yield were observed. Instead, significant influence of varied potassium fertilization on the fruits’ biological value was found. Potassium added in a form of KNO3 at a dose of 8 g K per plant resulted in the highest dry matter and vitamin C content in eggplant.
Growth and cropping of two cultivars of peach and nectarine in the conditions of the Sandomierska Plateau
Authors: Wociór Stanisław 
Published: August 2013

Abstract
In this experiment, the growth of peach and nectarine trees was determined to be related to the cultivar. ‘Inka’ peach trees grew weaker than ‘Harbinger’ trees. The ‘John Rivers’ nectarine was characterized by stronger growth than the ‘Harko’. The amount of crops produced by the trees was related to the cultivar and the meteorological conditions during winter and spring. ‘Inka’ produced higher yields and bigger fruits as compared to ‘Harbinger’. The ‘Harko’ cultivar provided significantly higher yields than the ‘John Rivers’ only in 2006. Peach and nectarine fruit production in the Sandomierska Plateau in the years 2004 − 2007 was risky. In 2006, damage to the flower buds during winter caused no crop yield in young peach trees and the older ones of the ‘Harbinger’ cultivar. A minor reaction to the temperature drop, down to -26.8oC, was found for nectarines in comparison with peach trees. In 2007, the spring frost injured flower pistils and caused a lack of crops from the studied cultivars.

Abstract
The aim of the research, which was carried out in the years 2002 − 2004, was the determination of the natural tendencies in the macroelement nutritional status and in the yielding of the standard cultivars of Anthurium cultorum Birdsey (‘Baron’, ‘Choco’, ‘Midori’, ‘Pistache’, ‘President’, ‘Tropical’ from Anthura B.V., the Netherlands) in the autumn-winter and spring-summer vegetations periods. The anthurium was grown in expanded clay with the use of standard nutrients in a drip fertigation system. It was found that an improvement of light conditions caused a significant increase in plant yielding. During the three years of the study, it was found that an essential influence was exerted by the vegetation period on the amount of phosphorus and potassium in the plants’ leaves. In the spring-summer period, a considerable decrease of phosphorus content in the plants was observed, but at the same time, there was an increase of potassium content. In the springsummer period, plant age affected the phosphorus and calcium content of the plants, while in the autumn-winter period, the phosphorus, potassium and calcium content was affected. A decrease in calcium, nitrogen and magnesium content was found in the spring-summer period, while the content of sulphur tended to increase. The obtained results could be a valuable instrument for the interpretation of index parts of plant analyses for diagnostic purposes.

Abstract
In 2003 - 2005 the impact of intercropping white cabbage ‘Bently F1’ with French Marigold (Tagetes patula nana ‘Kolombina’) and Pot Marigold (Calendula officinalis ‘Promyk’) on the occurrence of pest insects was estimated. On plots where cabbage was intercropped the number of cabbage aphid Brevicoryne brassicae L. and flea beetles Phyllotreta was significantly lower when compared with control variant (homogenous crop). Intercropping had an effect on the butterfly oviposition too. The lower number of eggs of the small white butterfly Pieris rapae L., large white butterfly P. brassicae L., cabbage moth Mamestra brassicae L. and larvae and pupae of the diamondback moth Plutella xylostella L. were observed on plots with Calendula and Tagetes. Intercropping with Pot Marigold was the most effective pest control on cabbage.

Abstract
This study presents the influence of major weather factors during the blackcurrant blossoming period on the yields of the ‘Ojebyn’, ‘Titania’ and ‘Roodknop’ cultivars, cultivated in Warmia (Olsztyn). The study was conducted for five years (2003-2007). Among the factors analysed were the currant yield, the duration of the blossoming period, average daily air temperature, the number of days with frost at the height of 2 m and at the ground level, total rainfall during the blossoming period and the number of days with rainfall during the blossoming period.
The statistical analysis of particular weather factors has shown that the number of days with frost contributed significantly to the yield of the fruit. A linear correlation analysis has shown that the yield of the three examined cultivars of blackcurrant depended on variable weather conditions during the blossoming period. The yield of the ‘Ojebyn’ cultivar was significantly correlated with the duration of the blossoming period, the number of days with frost and the number of days with rainfall. A significant correlation in the ‘Titania’ cultivar was found with the number of days with frost and with the total amount of rainfall during the blossoming period. The fruit yield from the ‘Roodknop’ cultivar in the five-year period under study depended only on one variable: the duration of the blossoming period. The highest yield was obtained from the ‘Titania’ cultivar.

Abstract
The aim of this study was to investigate the effect of organic fertilization on growth, several physiological parameters and yield of pepper plants (‛Buketen 50’). The field experiment was carried out at the experimental field of the Agroecological Centre of the Agricultural University of Plovdiv (Bulgaria), which is certified as an ecological farm. For the purpose of the research, the bio-fertilizer Lumbrical, produced by the Californian earthworm (Lumbricus rubellus), was used. Just before planting, two levels of the bio-fertilizer were applied 50 and 100 ml per plant. Thirty days after planting, a part of the plants were additionally fed with a solution of Lumbrical (200 ml per plant). During plant vegetation some biometrical indices characterizing plant growth were measured. The content of the plastid pigments and the leaf gas exchange were taken into account. The fertility of the pollen of the flowers was determined. The total amount of pigments in the dried and ground red pepper was analyzed.

Abstract
The aim of the present study was to investigate the influence of spraying with Aminoplant on the yield of two spinach cultivars in the spring and autumn cultivations. The experiment was carried out in 2008 and 2009 in the experimental station of the University of Agriculture in Krakow, Poland. Three factors were taken into consideration: (1) cultivar: ‘Rembrandt F1’ and ‘Spiros F1’; (2) time of cultivation: spring and autumn; (3) dose of Aminoplant: control (without Aminoplant), 1.5 dm3 ha-1 and 3.0 dm3 ha-1. The spinach yield was dependent on the time of production and cultivar type, and ranged between 18.6-44.8 t ha-1. Both cultivars yielded better in autumn cultivation. Spraying with Aminoplant had no effect on spinach yield. Dry matter content in spinach leaves was between 6.3-11.2 g 100 g-1. Spinach grown in the autumn had a greater content of dry matter in comparison to the spring cultivation. In 2009, ‘Rembrant F1’ was characterized by greater dry matter content than ‘Spiros F1’. Aminoplant in a dose of 3.0 dm3 ha-1 lowered dry matter content in spinach leaves as compared to the control. The nitrate content in spinach was differentiated (558-3506 mg NO3 kg-1 f.m.) and depended on the time of cultivation, the cultivar, and the Aminoplant dose.

Abstract
A survey was carried out on 38 commercial and experimental stone fruit orchards located in major growing areas of stone fruit trees in Poland to determine the incidence of lesser known viruses and phytoplasmas. Leaf samples from 145 sweet cherry and 102 sour cherry trees were tested for Little cherry virus 1 (LChV-1), Little cherry virus 2 (LChV-2), Cherry green ring mottle virus (CGRMV), Cherry mottle leaf virus (CMLV), and Cherry necrotic rusty mottle virus (CNRMV) using RT-PCR. Sixty samples collected from peach and 20 apricot trees were also tested for CGRMV. Eleven out of 145 sweet cherry and three out of 102 sour cherry trees were infected by LChV-1. CGRMV was detected in 10 sweet cherry, four sour cherry, 14 peach and two apricot trees. No LChV-2, CMLV and CNRMV were detected in any of the tested trees. Phloem tissue from samples of shoots collected from 145 sweet cherry, 102 sour cherry, 128 peach, 37 apricot, five nectarine and 20 European as well as Japanese plum trees were tested for phytoplasmas. The nested PCR of the extracted DNA with universal and specific primer pairs showed the presence of phytoplasmas in six sweet cherry, three sour cherry, nine peach, four apricot, one nectarine and three Japanese plum trees. The RFLP patterns of 16S rDNA fragments after digestion with RsaI, MseI, AluI, and SspI endonucleases indicated that selected stone fruit trees were infected by two distinct phytoplasmas belonging to the apple proliferation group. The stone fruit trees infected by LChV-1, CGRMV and phytoplasmas were grown in orchards localised in all seven regions

Published: August 2013

Abstract
The development of the art of garden design has brought about the emergence of naturalistic or ecological gardens. This paper presents a brief historical overview of this period in gardening, and provides examples of contemporary applications. Plants can function as absorbents of metals and therefore there is also the possibility of their practical application in techniques for purifying the environment from metallic contamination. An urgent need to create collections of this unique wild plant material has been stressed. Naturalistic gardens designed in appropriate areas have been proposed as an adequate form of setting up in vivo collections composed of numerous native taxa.
CLINICAL BIOCHEMISTRY DATABASE ANALYSIS: A RESTRICTED DIALYSIS COHORT /
Authors: Bellini Martina , Paparella Paolo 
Published: August 2013

Summary
Background: A retrospective study was undertaken to inves- tigate the biochemistry data of a restricted cohort of dialysis- related arthropathy patients. The aim of our study was to characterize this specific cohort of dialysis patients using a clinical chemistry database analysis.
Methods: An elaboration of more than 160,000 items of biochemical data, collected from 2001 to 20|11, was made of 50 patients, 25 with dialysis-related arthropathy and 25 patients asymptomatic for arthropathy. A Student's t-test was applied, considering a P-value less than 0.05 as statistically significant.
Results: Significant and relevant unexpected biochemical dif- ferences were found between the two groups of patients. The serum level of p2-microglobulin was similar, while fer- ritin values were significantly higher in symptomatic patients. We excluded the possibility that the ferritin difference between the two groups was due to different iron storage and to an inflammatory profile.
Conclusions: The correct use of a biochemical database could permit to identify significant values which must be cor- related with clinical data, but which could be the first step to a wider research.

Abstract
The phenolic compound composition, antioxidant activity and impact on cell viability of edible flower extracts of Allium schoenoprasum; Bellis perennis; Cichorium intybus; Rumex acetosa; Salvia pratensis; Sambucus nigra; Taraxacum officinale; Tragopogon pratensis; Trifolium repens and Viola arvensis was examined for the first time. Total phenolic content of the flowers of these plants fell between 11.72 and 42.74 mg of tannin equivalents/kg of dry matter. Antioxidant activity ranged from 35.56 to 71.62 g of ascorbic acid equivalents/kg of dry matter. Using the Human Hepatocellular Carcinoma cell-line (HepG2) and the Human Immortalized Non-tumorigenic Keratinocyte cell line (HaCaT), we assessed cell viability following a 3 day incubation period in media containing 25, 50, 75 and 100 μg/ml of total phenolic compounds using a colorimetric MTT assay. These three properties could make the herbs useful in treatment of various diseases like cancer. The tested extracts had significant effects on cell viability, but the effects were dependent not only on the phenolic compound concentration and the edible flowers species, but also on the phenolic compound and antioxidant profiles. In addition, responses differed between cell lines.

Abstract
Hypericum perforatum L. is a common perennial plant with a reputed medicinal value. Investigations have been made to develop an efficient protocol for the identification and quantification of secondary metabolites in hairy roots (HR) of Hypericum perforatum L. HR were induced from root segments of in vitro grown seedlings from H. perforatum, after co-cultivation with Agrobacterium rhizogenes A4. Transgenic status of HR was confirmed by PCR analysis using rolB specific primers. HR had an altered phenolic profile with respect to phenolic acids, flavonol glycosides, flavan-3-ols, flavonoid aglycones and xanthones comparing to control roots. Phenolics in control and HR cultures were observed to be qualitatively and quantitatively distinct. Quinic acid was the only detectable phenolic acid in HR. Transgenic roots are capable of producing flavonol glycosides such as quercetin 6-C-glucoside, quercetin 3-O-rutinoside (rutin) and isorhamnetin O-hexoside. The HPLC analysis of flavonoid aglycones in HR resulted in the identification of kaempferol. Transformed roots yielded higher levels of catechin and epicatechin than untransformed roots. Among the twenty-eight detected xanthones, four of them were identified as 1,3,5,6-tetrahydroxyxanthone, 1,3,6,7-tetrahydroxyxanthone, γ-mangostin and garcinone C were de novo synthesized in HR. Altogether, these results indicated that H. perforatum HR represent a promising experimental system for enhanced production of xanthones.

Published: August 2013

Abstract
The aim of this study was to assess the phoretic relationship between two beetle species of the genus Tetropium and mites from order Mesostigmata. The study was conducted in the Białowieża Forest, which is recognized as one of Europe’s last natural forest areas. Insects were caught over a period of 8 weeks in 72 attractant traps (type Intercept IPM). In total 1250 specimens of genus Tetropium were collected. We analyzed 524 beetles, including 295 specimens of T. castaneum and 229 specimens of T. fuscum. On 49 beetles (9.4%) there were 785 individuals of Trichouropoda shcherbakae (Trematuridae). Mites were more common on T. fuscum, which carried 82% of all collected deutonymphs. Most of the mites found on beetles were attached to their legs. This study reports on changes in the intensity of phoresy in time and location of mite deutonymphs on their host species.
Effect of temporal modification and vowel context on speech perception in individuals with auditory neuropathy spectrum disorder (ANSD)
Authors: Pottackal Mathai Jijo , Yathiraj Asha 
Published: August 2013

Objectives:
The study aimed to investigate the effect of time-scale modification on consonant perception in individuals with an auditory neuropathy spectrum disorder (ANSD). The study also evaluated the effect of vowel context on consonant perception.

Study design:
Eight individuals with ANSD in the age range of 15 to 24 years participated in the study. Their perception of eight stops and two liquids in the context of the vowels /a/, /i/ and /u/ were studied. The stimuli were stretched by 25%, 35% and 50% using pitch synchronous overlap and add algorithm.

Results:
It was found that 25% stretching resulted in significant improvement in perception in all three vowel contexts, while 35% stretching improved perception only in the context of /a/. However, 50% stretching resulted in deterioration in performance in all three vowel contexts. Furthermore, consonant perception in the context of /a/ and /u/ were significantly higher than that of /i/ in all the stretch conditions. Sequential information analysis revealed that perception of place and voicing were lowest in the context of /i/ compared to that of /a/ and /u/.

Conclusion:
Stretching the entire stimuli by a factor of 25% improves consonant perception in individuals with ANSD. In contrast, stretching beyond 25% resulted in either no improvement or deterioration in consonant perception. This information can be used to create a signal-processing algorithm that stretches the entire speech signal. Hence, without having to laboriously increase only the transition duration manually, improvement in speech perception can be brought about by stretching the whole signal. Additionally, consonant perception in individuals with ANSD is influenced by vowel context and hence two extreme vowels need to be used while studying the vowel context effect.
Comparison of perioperative outcomes following open versus minimally invasive transforaminal lumbar interbody fusion in obese patients

Object
Minimally invasive (MI) transforaminal lumbar interbody fusion (TLIF) has proven to be effective in the treatment of spondylolisthesis and degenerative disc disease (DDD). Compared with the traditional open TLIF, the MI procedure has been associated with less blood loss, less postoperative pain, and a shorter hospital stay. However, it is uncertain whether the advantages of an MI TLIF also apply specifically to obese patients. This study was dedicated to evaluating whether obese patients reap the perioperative benefits similar to those seen in patients with normal body mass index (BMI) when undergoing MI TLIF.

Methods
Obese patients—that is, those with a BMI of at least 30 kg/m2—who had undergone single-level TLIF were retrospectively identified and categorized according to BMI: Class I obesity, BMI 30.0–34.9 kg/m2; Class II obesity, BMI 35.0–39.9 kg/m2; or Class III obesity, BMI ≥ 40.0 kg/m2. In each obesity class, patients were stratified by TLIF approach, that is, open versus MI. Perioperative outcomes, including intraoperative estimated blood loss (EBL), complications (overall, intraoperative, and 30-day postoperative), and hospital length of stay (LOS), were compared. The chi-square test, Fisher exact test, or 2-tailed Student t-test were used when appropriate.

Results
One hundred twenty-seven patients were included in the final analysis; 49 underwent open TLIF and 78 underwent MI TLIF. Sixty-one patients had Class I obesity (23 open and 38 MI TLIF); 45 patients, Class II (19 open and 26 MI); and 21 patients, Class III (7 open and 14 MI). Overall, mean EBL was 397.2 ml and mean hospital LOS was 3.7 days. Minimally invasive TLIF was associated with significantly less EBL and a shorter hospital stay than open TLIF when all patients were evaluated as a single cohort and within individual obesity classes. Overall, the complication rate was 18.1%. Minimally invasive TLIF was associated with a significantly lower total complication rate (11.5% MI vs 28.6% open) and intraoperative complication rate (3.8% MI vs 16.3% open) as compared with open TLIF. When stratified by obesity class, MI TLIF was still associated with lower rates of total and intraoperative complications. This effect was most profound and statistically significant in patients with Class III obesity (42.9% open vs 7.1% MI).

Conclusions
Minimally invasive TLIF offers obese patients perioperative benefits similar to those seen in patients with normal BMI who undergo the same procedure. These benefits include less EBL, a shorter hospital stay, and potentially fewer complications compared with open TLIF. Additional large retrospective studies and randomized prospective studies are needed to verify these findings.
