Evaluation of the bacteriocin produced by strain 9 lactic acid bacteria isolate for biopreservation

Aim: This study aimed to determine the effect of the bacteriocin produced by strain 9 lactic acid bacteria (LAB) isolate on the biopreservation of beef. Materials and Methods: The strain 9 LAB isolate was identified conventionally by culturing with de Man, Rogosa, and Sharpe broth medium followed by Gram staining and catalase testing. The molecular confirmation of the isolate involved analyzing the 16S rRNA gene with specific primers, that is, B27F (5-AGAGTTTGATCCTGGCTCAG-3) and U1492R (5-GGTTACCTTGTTACGACTT-3). Then, the isolate was centrifuged to evaluate the bacteriocin production, and the effect of the biopreservative activity in beef was evaluated by measuring the NH3 produced with the Eber test and the organoleptic acceptance from expert panels. Results: This study confirmed that the strain 9 LAB isolate was a strain of Pediococcus pentosaceus, and the bacteriocin product showed biopreservative potential. The biopreservative potential was characterized by a significant decline in the production of NH3 and the panel’s acceptance of the texture and tenderness of the beef, compared with the control, after 10 days of constant treatment. Conclusion: This study highlighted the high biopreservative potency of pediocin produced by P. pentosaceus strain 9. This was noted by the production of NH3 and the modifications in texture and tenderness.
Characterization of field strains of infectious bursal disease virus (IBDV) using molecular techniques

This study was aimed to apply different molecular techniques in the genotyping of field strains of infectious bursal disease virus (IBDV) currently present in the United States and in some other countries. The different techniques included the reverse transcription-polymerase chain reaction / restriction fragment length polymorphism (RTPCR/RFLP), heteroduplex mobility assay (HMA), nucleotide and amino acid sequence analysis, and riboprobe in situ hybridization (ISH). From 150 samples analyzed from the United States, 80% exhibited RFLP identical to the variant Delaware E strain, other strains detected included Sal-1, D-78, Lukert, PBG-98, Delaware A, GLS IBDV standard challenge strain –like (STC-like). The analysis of the deduced amino acid sequence of the VP2 hypervariable region from six strains classified as Delaware variant E, revealed some amino acid substitutions that make them somewhat different from the original variant E strain isolated in the mid 1980s. The isolate 9109 was classified as a standard strain, but, it exhibited a unique RFLP pattern characterized by the presence of the Ssp I restriction site characteristic of the very virulent IBDV (vvIBDV) strains. The pathogenic properties of this isolate were compared to those of isolate 9865 (variant strain) and the Edgar strain. All three strains induced subclinical disease, however by in situ hybridization some differences in the tissue tropism were observed. The viral replication of the variant isolate 9865 was more restricted to the bursa of Fabricius. Isolate 9109 and the Edgar strain were also observed in thymus, cecal tonsils, spleen, kidney and proventriculus. A variety of inactivated IBDV strains received from Latin America were detected by RT-PCR/RFLP. The more interesting findings include the presence in Mexico and Venezuela of IBDV strains with unknown RFLP patterns, and the observation of RFLP patterns indicative of vvIBDV strains in Brazil and Dominican Republic. Finally, the HMA was evaluated as a method for genotyping IBDV. The HMA was able to differentiate between standard, antigenic variants and very virulent strains. Minor differences between antigenic variants were also detected. The results obtained by HMA were similar to that obtained with RFLP and phylogenetic analysis.
The Effect of Muscular Endurance interval Training on some Cardiovascular Markers in Trained runners

The potential role of training on cardiovascular physiological markers improvement is frequently reported. Although the main mechanism involved in these changes is not understood well. This study determined the effect of one period of muscular endurance interval training on cardio-respiratory function and some physiological structures in the cardiovascular system of a group of people. To do so, 20 young men (mean age=19 & mean weight=78Kg) voluntarily participated in this study. They were randomly divided into two control and exercise (muscular endurance interval training) groups. Two-dimensional echocardiogram with Doppler was applied to measure the structural and functional variables of heart. Statistical data was analyzed using T-independent test and correlated t-test. Administering eight weeks of muscular endurance interval training significantly affected the research variables (p<0.05). That is, following variables were maximally affected: Maximal Oxygen Consumption (VO2max), Maximal Aerobic Speed (MAS), Anaerobic Threshold Speed (ATS), runners’ ejection fraction percentage and record. Based on these results, it is concluded that using muscular endurance interval training is potentially important in improving cardiovascular physiological parameters.
Effects of core stability exercise on rehabilitation in stroke patients with hemiplegia: a meta-analysis

Objective : To evaluate the effects of core stability exercise (CST) on rehabilitation in stroke patients with hemiplegia. Methods : Randomly controlled trials about the effects of CST on rehabilitation in stroke patients with hemiplegia were searched in the database, including PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, CBM and VIP. Search terms include “core stability training / core stability exercise / core stabilization training / core stabilization exercise / core strength training / core strength exercise” and “stroke / brain ischemia / cerebral infarction / cerebral hemorrhage / intracranial thrombosis / brain hemorrhage / cerebrovascular disorder / cerebrovascular accident, cerebrovascular disease / hemiplegia / hemiparesis / stroke rehabilitation”. Study screening, data extraction and quality assessment were conducted by two researchers independently. Data was analyzed using RevMan 5.3 software. Results : Totally 11 studies and 704 patients were included with 352 patients in experiment group and 352 in control group. Results of meta-analysis showed that combination of CST and conventional rehabilitation had better effects on trunk control [MD = 10.44, 95% CI (8.83-12.04), P < 0.001], banlace [MD = 5.6, 95% CI (4.81-6.39), P < 0.001], activities of daily living [MD = 12.06, 95% CI (7.65-16.46), P < 0.001], ambulation functional [MD = 0.72, 95% CI (0.32-1.12), P < 0.001] and walking speed [MD = 3.39, 95% CI (2.03-4.76), P < 0.001] than conventional rehabilitation, but there is no clear difference on walking stride [MD = 2.52, 95% CI (-0.25-5.29), P = 0.07] between two groups. Conclusion : CST together with conventional rehabilitation can better improve trunk control, banlace, activities of daily living, ambulation functional and walking speed in stroke patients compared with conventional rehabilitation, but can not make the walking stride better significantly. However, since the conclusion of this meta-analysis was drawn based on middle quality RCTs, future high quality researchs should be conducted to confirm its positive intervention effects.
Profiling for Confidence: Debugging Relationships among Urban Spatio-Temporal Datasets

We aim to help users identify potential issues in spatio-temporal data and thus gain trust in the results they derive from such data -- a crucial benefit in the era of data science and big data. We propose a framework for profiling spatio-temporal relationships that automatically identifies data slices that deviate from what is expected, which can be further analyzed for quality issues and/or potential effects on analysis' results. We describe the profiling methodology and present cases studies using real urban datasets, then emphasizing the need for spatio-temporal profiling to build trust on data analysis' results.

Validity and reliability of the Turkish version of the modified Yale Preoperative Anxiety Scale

Background/aim The modified Yale Preoperative Anxiety Scale (m-YPAS) is widely used to measure children’s anxiety levels. The aim of this study was to translate the m-YPAS into Turkish and test its validity and reliability in Turkish children. Materials and methods The English version of the m-YPAS was translated into Turkish using the forward-back-forward translation technique. This study enrolled 120 children. The m-YPAS was administered to 120 children who were recorded on video. The State-Trait Anxiety Inventory for Children (STAIC) was used for only 30 of 120 children. The videotapes were evaluated by two experienced observers [an anesthesiologist, ObA(an), and a psychologist, ObB(ps)]. The interrater reliability, concurrent validity, sensitivity, specificity, and positive and negative predictive values were analyzed. Results The mean age of the children was 7.8 ± 2.2 years. The weighted kappa values of the m-YPAS between observers were in substantial agreement (κw = 0.74–0.80) and almost perfect agreement (κw = 0.84–0.85). The Cronbach alpha values were high [α = 0.85 for ObA(an) and α = 0.86 for ObB(ps)]. The correlation between m-YPAS and STAIC showed good agreement (P < 0.05). The sensitivity and specificity were high, and the predictive value was 92.86%. Conclusion The Turkish version of the m-YPAS can be applied as a reliable and valid observational questionnaire for Turkish children.

For further accomplishment, synthetic and semantic word relevance in high dimension vector space: Bangla word embedding system(word2vec) is added to the system as sentence representation along with Positioning Encoding (PE) and which outperforms both memory network GRU and LSTM precisely.
Effects of four varieties of Lathyrus sativus (Fabaceae) seeds on the bionomics of Callosobruchus maculatus (Coleoptera: Chrysomelidae)

Abstract The effect of four varieties of Lathyrus sativus Linnaeus (Fabaceae) seeds (Bio L 212 Ratan, Nirmal B-1, WBK-14-7, and WBK-13-1) on the bionomics of Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae: Bruchinae) was studied under laboratory conditions. Total larval developmental time was longer on WBK-13-1 than Bio L 212 Ratan. Adult emergence was highest on Bio L 212 Ratan followed by Nirmal B-1, WBK-14-7, and WBK-13-1. The development and fecundity were related with nutrient and antinutritional factors of khesari seeds. Total carbohydrates and proteins were highest in Bio L 212 Ratan and Nirmal B-1 while lipids and nitrogen were highest in Bio L 212 Ratan and least in WBK-13-1. Amino acids were higher in Nirmal B-1 and WBK-13-1. Phenols were greatest in Nirmal B-1 and least in Bio L 212 Ratan and WBK-14-7. β-ODAP was higher in Bio L 212 Ratan and Nirmal B-1. The lower levels of carbohydrates, proteins, lipids, nitrogen, water content, and higher trypsin inhibitor activity of WBK-14-7 and WBK-13-1 may explain the higher developmental time and lower fecundity of C. maculatus on these varieties. These results suggest that infestations of C. maculatus may be easier to manage on WBK-14-7 and WBK-13-1 than on the other varieties of khesari seeds.
Multiparametric optimization of multispectral optoacoustic tomography for deep tissue imaging

Over the last decade fluorescent reporter technologies (both fluorescent probes and proteins) have become a very powerful imaging tool in everyday biomedical research. Multispectral optoacoustic tomography (MSOT) is an emerging imaging technology that can resolve fluorophore concentration in small animals situated in deep tissue by multispectral acquisition and processing of optoacoustic signals. In this work, we study the optimum operating conditions of MSOT in imaging fluorescence activity in small animals. The performance of various fluorochromes / fluorescent proteins is examined and it is shown that the new infrared fluorescent protein is an order of magnitude brighter than the red ones. Finally, wavelength reduction after principle component analysis shows, that accurate unmixing and 3D reconstruction of the distribution of fluorochromes is possible only with 2 or 3 wavelengths.

The Impact of IS Investment on Bank’s Performance based on MCDM Techniques

: While banks are investing heavily in information system (IS), the results of studies of the relation between those investments and superior performance of the firm are mixed. Many studies have analysed the impact of IS investment on firm performance, without taking into account the non-financial firm’s performance, This paper proposes a framework to evaluate the non-financial bank’s performance based on an approach combining two most used MCDM methods and the impact of IS investment on this performance. The results of this study that dealt with fifty banks show that IS investment does not insure superior performance.
Metabolomic Investigation of Tenderness and Aging Response in Beef Longissimus Steaks

A study was conducted to identify molecular changes reflective of beef tenderness variation and tenderization during postmortem aging. Carcasses (U.S. Select) were selected to represent extremes in tenderness (n = 20; 10 per class). Two pairs of adjacent longissimus lumborum steaks from each strip loin were blocked by location and assigned to each aging time (2, 7, 14, or 28 d postmortem). One steak from each pair was designated for slice shear force determination and the other was used for sarcomere length, western blotting for desmin, and non-targeted LC- and GC–MS metabolite profiling. Tough steaks had higher (P < 0.001) slice shear force values than tender steaks, and increasing aging time decreased (P < 0.001) slice shear force values. Tender steaks had a greater (P < 10–4) proportion of desmin degraded than tough steaks, and increasing aging time increased (P < 10–22) desmin degradation in steaks from both classes. From 2,562 profiled metabolites, 102 metabolites were included in the final analysis after statistical screening. Twenty-eight metabolites could be annotated and loosely categorized into amino acids/peptides (n = 16), metabolism intermediates (n = 7), glycosides (n = 4), and fatty acids and phospholipids (n = 3). Amino acids were primarily associated with desmin degradation. Increased glucose levels were strongly associated to the tender classification and moderately associated to increased proteolysis, while increased glucose-6-phosphate was strongly related to the tender class but was related to decreased proteolysis. Increased malic acid was strongly associated to the tough classification, increased slice shear force, and decreased proteolysis. Increased levels of 3-phosphoglyceric acid and glycerol-3-phosphate was moderately associated with increased slice shear force and decreased proteolysis. These data indicate that accumulation of amino acids during aging is strongly related to postmortem proteolysis and may provide evidence of the fate of proteins degraded postmortem. Measures of glucose, glucose-6-phosphate, and malic acid concentrations may provide a metabolic fingerprint indicative of tenderness differences in beef longissimus.
Contribuição das ramificações e a evolução do índice de área foliar em cultivares modernas de soja

The purposes of this study were to quantify the branches contribution and the leaf area index evolution in modern cultivars of soybean with different maturity groups, stem termination, sowing in different dates and producing regions of soybean in Rio Grande do Sul. Field experiments were conducted during the growing season 2013/2014 in Santa Maria, Julio de Castilhos and in three soybean crops on the municipalities of Restinga Seca, Tupancireta and Agua Santa. It were carried out analysis (occurrence date) of reproductive stages and determination total, maximum, of main stem and of branches of leaf area index in thirteen cultivars of soybean. The leaf area index on the branches contributes with about 31%, 12.3% and 11% of the total leaf area index on the determinate cultivars and with 20.2%, 11.8% and 9% of the total leaf area index on the indeterminate cultivars sowing in September, November and February, respectively, in Santa Maria. Most cultivars showed a reduction on total leaf area index, maximum, of main stem and of branches with the delay on planting date, independently of the maturity group and stem termination.
Isolation of sooty blotch and flyspeck fungi from apple surface by picking up the thalli

The contaminations make it difficult to isolate sooty blotch and flyspeck fungi from apple surface. In this research we used the technique to pick up the thallus directly from apple surface under a stereomicroscope. For each sample, 10-15 slant repeats were needed to insure at least two to three isolations could grow up. Compared with common methods repor- ted previously, this technique is of high efficiency and less contamination rate.
Electronic Contract Drafting Based on Risk and Trust Assessment

Contracts protect the parties involved in a commercial transaction, but the negotiating and drafting processes are often so unstructured that the parties cannot be certain that their interests are indeed secured. This paper proposes a structured, model-driven approach to contracting that each party to a contract can use to assess the personal risk and trust it entails and decide whether it adequately protects their interests. If it does not, the model can support negotiations to amend the contract. The risk/trust model is based on the authors' earlier research on a generic model of trust for use in developing trust services for e-commerce.
Mating behavior and fertilization of the freshwater rotifer, Brachionus calyciflorus

The mating process of Brachionus calyciflorus may be seperated into five phases.There was no significant effect of sex ratio of female to male between 1∶1 and 6∶1 on the percent fertilization,except that the percent fertilizations were all 100% when the sex ratio was 1∶3 and 1∶2.The percentage of mictic females that could be fertilized and males that were capable of fertilization declined with their aging.All mictic females were susceptible to fertilization until age 4h.Susceptibility declined non linearly according to the quadratic equation Y =166 6386-17 813 X +0 4837 X 2 . By age 18h,all mictic females no longer could be fertilized.Only 90 63%～91 61% of newborn male were capable of fertilization.This level of fertility held until age 8h,then declined linearly: Y =152 5054-6 6329 X There were no significant effects of the sex ratio and the age of the copulating mictic female and male on the number of resting eggs produced by one fertilized mictic female.
