Purpose: On the grounds of comprehensive assessment of the 2 groups of patients after intramedullary tumors surgery compare a neurological outcome in the early postoperative period. The first group was operated with intraoperative monitoring and the second group was operated before the introduction of neurophysiological control. During the monitoring try to identify predictors of successful outcome for patients after intramedullary tumors surgery.
The study included 48 patients with intramedullary tumors of cervical and thoracic localization. Complex neurological examination was performed before surgery and 2 weeks after surgery and included: as-sessment of neurological status on McCormick Scale, functional outcome rated on SCIM III Scale, the total mobility was evaluated on Rivermid Index mobility and paresis we rated on the ASIA Motor Score scale. The study group consisted of 26 patients operated with intraoperative monitoring and control group consisted of 22 patients operated before the introduction of intraoperative monitoring in neurosurgical practice. The trial comprised patients with a functional status I-III rated on McCormick Scale.
After assessing the 2 groups according the SCIM III scale it was found out the persistence of the level in the study group (p=0,044) and a decrease of the final score in the control group. Comparing the activity level on a Rivermid scale we identified improvement in the study group (р=0,034) and retention of activity in the control group. We detected that in the study group where we used intraoperative monitoring, the level of paresis accord-ing to ASIA Motor Score preserve at the preoperative level, and the growth of paresis level in the control group (p&#60;0,05). Preservation of MEP amplitude &#62; 50% at the end of the operation is a predictor of saving muscle strength at the preoperative level.
Patients, who underwent surgery with the use of intraoperative monitoring are more active and indepen-dent from outside help in the early postoperative period.

Authors: Szabó L. , Horváth Zs. H. 
Published: July 2015

Abstract
The paprika oleoresin, that is an oil soluble extract from the fruits of Capsicum Annum Linn or Capsicum Frutescens, is used often to raise the colour agent content of paprika powders. We investigated how the colour agent content of paprika powder samples with added oleoresin change in the course of storage. The colour agent content of 7 different quality powders was increased with 7-75% using two types of oleoresin. The initial colour agent content of the samples changed between 41 and 169 ASTA units. The powders were made from Chinese, Peruvian and Hungarian paprika. The colour agent content of the samples was measured throughout 10 months. The measured values were analysed using ANOVA. The decrease of colour agent content varied between 22 and 51 percent, while the average reduction was 33 percent. The initial colour agent content of the paprika powder samples did not influence the colour agent content decrease significantly. The effect of the quantity of added oleoresin did not influence either the colour agent content decrease significantly. The decrease of the colour agent content of the Hungarian paprika samples significantly differs from the Chinese and Peruvian paprika samples colour agent content decrease.

Abstract
The study evaluated the proliferative activity of immunocompetent cells in the jejunal and iliac lymph nodes of prepubertal female wild boars exposed to deoxynivalenol and zearalenone in naturally contaminated feed. The evaluation was performed with the use of the MTT assay and 2 mitogens: lipopolysaccharide (LPS) and concanavalin A. Intensified proliferative processes in T and B lymphocytes were revealed. The mitogenic activity of LPS was more expressed in the lymphocytes of both iliac and jejunal lymph nodes in comparison with the control group. Proliferative activity was higher in iliac lymph nodes than in jejunal lymph nodes. A reverse trend was observed in the percentage of live cells, which was higher in jejunal lymph nodes during the evaluation of lymphocyte proliferation.

Abstract
The purpose of this study was to assess the possible influence of beavers on the contamination of lake water with zoonotic parasites Giardia duodenalis and Cryptosporidium spp., with respect to the risk to human health. A total of 79 water samples were taken around the habitats of beavers from 14 localities situated in the recreational Masurian Lake District (north-eastern Poland). Water was sampled in the spring and autumn seasons, at different distances from beavers’ lodges (0-2, 10, 30, and 50 m). The samples were examined for the presence of (oo)cysts of zoonotic protozoa Giardia duodenalis and Cryptosporidium spp. by direct fluorescence assay (DFA) and by nested and real time PCR. By DFA, the presence of Giardia cysts was found in 36 samples (45.6%) and the presence of Cryptosporidium oocysts in 26 samples (32.9%). Numbers of Giardia cysts, Cryptosporidium oocysts, and summarised (oo)cysts of both parasites showed a significant variation depending on locality. The numbers of Giardia cysts significantly decreased with the distance from beavers’ lodges while the numbers of Cryptosporidium oocysts did not show such dependence. The amount of Giardia cysts in samples collected in spring was approximately 3 times higher than in autumn. Conversely, a larger number of Cryptosporidium oocysts were detected in samples collected in autumn than in spring. By PCR, Giardia DNA was found in 38 samples (48.1%) whereas DNA of Cryptosporidium was found in only 7 samples (8.9%). Eleven Giardia isolates were subjected to phylogenetic analysis by restriction fragment length polymorphism PCR or sequencing which evidenced their belonging to zoonotic assemblages: A (3 isolates) and B (8 isolates). In conclusion, water in the vicinity of beavers’ lodges in the tested region was markedly contaminated with (oo)cysts of Giardia duodenalis and Cryptosporidium spp., which confirms the potential role of beavers as a reservoir of these parasites and indicates a need for implementation of appropriate preventive measures to protect tourists’ health.

Abstract
Semen was collected from Polish Halfbred stallions. Twenty individuals from 3 to 4 years of age were selected for the study. At least one ejaculate from each stallion was collected and assessed. Sperm morphology was evaluated using Papanicolaou stain, SpermBlue®, and a complex of eosin and gentian stain, whereas unstained slides were used as control samples. Morphometric measurements were performed on 100 randomly selected sperm heads in each ejaculate. The length, width, perimeter, and surface area of the sperm head were measured. The frequency of nuclear vacuoles was determined as well. Tygerberg’s strict criteria, which most precisely characterise the sperm head, were used in the morphological evaluation of the sperm. The results obtained indicate that in the case of staining with SpermBlue® and with eosin+gentian complex, the morphometry of the sperm head seems to be most similar to that observed in unstained smears. It also seems that neither shrinking nor swelling is uniform in the various staining techniques (Papanicolaou stain). Moreover, it appears that in comparison with unstained sperm, all methods caused the width of the head to increase as a result of swelling.

Improving Community Detection in Time-Evolving Networks Through Clustering Fusion
Authors: Jin Ran , Kou Chunhai , Liu Ruijuan 
Published: July 2015

Abstract
Traditional community detection algorithms are easily interfered by noises and outliers. Therefore, we propose to leverage a clustering fusion method to improve the results of community detection. Usually, there are two issues in clustering ensembles: how to generate efficient diversified cluster members, and how to ensembles the results of all members. Specifically: (1) considering the time evolving characteristic of real world networks, we propose to generate clustering members based on the snapshot of networks, where the split based clustering algorithms are performed; (2) considering the difference in the distribution of the cluster centers in each clustering member and the actual distribution, we ensemble the results based on a maximum likelihood method. Moreover, we conduct experiments to show that our method can discover high quality communities.
The structure of Na+-translocating of NADH:ubiquinone oxidoreductase of Vibrio cholerae: implications on coupling between electron transfer and Na+ transport

Published: July 2015

AbstractThe Na+-translocating NADH:ubiquinone oxidoreductase (Na+-NQR) ofVibrio choleraeis a respiratory complex that couples the exergonic oxidation of NADH to the transport of Na+across the cytoplasmic membrane. It is composed of six different subunits, NqrA, NqrB, NqrC, NqrD, NqrE, and NqrF, which harbor FAD, FMN, riboflavin, quinone, and two FeS centers as redox co-factors. We recently determined the X-ray structure of the entire Na+-NQR complex at 3.5-Å resolution and complemented the analysis by high-resolution structures of NqrA, NqrC, and NqrF. The position of flavin and FeS co-factors both at the cytoplasmic and the periplasmic side revealed an electron transfer pathway from cytoplasmic subunit NqrF across the membrane to the periplasmic NqrC, and via NqrB back to the quinone reduction site on cytoplasmic NqrA. A so far unknown Fe site located in the midst of membrane-embedded subunits NqrD and NqrE shuttles the electrons over the membrane. Some distances observed between redox centers appear to be too large for effective electron transfer and require conformational changes that are most likely involved in Na+transport. Based on the structure, we propose a mechanism where redox induced conformational changes critically couple electron transfer to Na+translocation from the cytoplasm to the periplasm through a channel in subunit NqrB.
Regulatory role of charged clusters in the N-terminal domain of BetP from Corynebacterium glutamicum
Authors: Waclawska Izabela , Ziegler Christine 
Published: July 2015

AbstractThe trimeric transporter BetP counteracts hyperosmotic stress by a fast increase in transport rate in order to accumulate the compatible solute betaine. The positively charged α-helical C-terminal domain acts as an osmosensor perceiving the increase in the internal potassium (K+) concentration. A second, still unidentified stimulus originates from stress-induced changes in the physical state of the membrane and depends on the amount of negatively charged lipids. BetP possesses a 60-amino acid (aa)-long negatively charged N-terminal domain, which is predicted to adopt a partly helical fold affecting osmoregulation by an unknown mechanism. It is assumed that the C-terminal domain, the N-terminal domain, and negatively charged lipids interact during stress sensing and regulation. Here, we have investigated the regulatory role of negatively charged clusters in the N-terminal domain. We identified one cluster, Glu24Glu25, to be crucial for osmoregulation. Cross-linking studies revealed an interaction between the C- and N-terminal domains of adjacent protomers modulating transport activation. A regulatory partner-switching mechanism emerges in which the C-terminal domain changes its interaction with the N-terminal domain of its own promoter and negatively charged lipids to an interaction with the N-terminal domain of an adjacent protomer and lipids bound to the central cavity of the BetP trimer.

Published: July 2015

Abstract
Oxide dispersion strengthened (ODS) ferritic steels are the leading candidates of fuel cladding for Generation IV nuclear reactors due to their excellent properties such as excellent radiation tolerance and high-temperature creep strength. Mechanical milling with the aim of a fine dispersion of oxides in the metal matrix becomes the main process for the production of ODS steels. In order to clarify the influence of milling time on the precursor powders for 15Cr-ODS steel, the morphology and properties of mechanical alloying (MA) powders with different milling time were investigated by scanning electron microscopy (SEM), laser diffraction particle size analyzer, X-ray diffraction (XRD) and Vickers hardness tester. The experimental results showed that the powder was fractured and welded with rotation and vibration of container during mechanical milling. The mean powder size increased (0–1 h) firstly then decreased (2–60 h). Extending milling time to 70 h, the mean powder size increased again. The grain size decreased quickly at the initial stage of milling process (0–2 h) then trended to reach a saturation value. The Vickers hardness increased rapidly at the initial stage of milling, then reached a saturation value.
An acoustic study of Luganda liquid allophones
Authors: Myers Scott 
Published: July 2015

AbstractTranscription-based descriptions of Luganda (Bantu, Uganda) have stated that there is a rhotic (r) in the language that occurs only after a front vowel, in complementary distribution with a lateral (l) that occurs only elsewhere. However, these descriptions of the pattern have disagreed about the nature and distribution of the sounds involved. Such a pattern has been reported in a number of Bantu and non-Bantu languages, and it is intriguing because its phonetic basis is not obvious, since there is nothing rhotic about a front vowel or lateral about a non-front vowel. To clarify the facts and provide insight into this kind of pattern, a production study was conducted in which Luganda speakers produced the liquid in varying vocalic contexts. F1, F2, duration, mean harmonics-to-noise ratio (HNR), and intensity were measured. The results support the characterization of the liquid after a front vowel as a nonlateral tap, and elsewhere as a lateral sonorant. But the intensity data also show a continuum in the degree of tongue tip constriction, ranging from approximant to tap, depending on the frontness of both the preceding and following vowels. The pattern of distribution is thus more complex and gradient than has been evident from transcriptions alone.

Published: July 2015

Abstract

Objective: Our objective is to compare the efficacy of combination regimen (salbutamol and nifedipine) against single regimen (nifedipine alone) in preventing preterm births among women with preterm labor.

Results: A total of 76 women with gestational age (GA) ranging from 24+0 to 35+6 weeks, who sought treatment for preterm labor with or without cervical dilatation, were recruited for the prospective cohort study. Of these, 38 (50%) had single tocolytic regimen and 38 (50%) had combination tocolytic regimen. The mean GAs at admission were similar for both groups at 31 weeks (±2.93) for Group 1 and 30.9 weeks (±2.88) for Group 2 (P=0.873). The mean GAs at delivery were 37.8 weeks (±1.98) for the single regimen and 36.2 weeks (±3.26) for the combined regimen (P=0.011). The mean tocolytic to delivery interval for the single regimen was longer at 6.74 weeks (±3.13) as compared with 5.21 weeks (±3.61) for the combination regimen (P<0.05). Those on the combination regimen complained of more adverse effects (P<0.001).

Conclusion: Our study results suggested that the use of nifedipine as a single tocolytic regimen is as effective as the combination regimen in the delay of preterm births and has much less side effects. Hence, we recommend the sole use of nifedipine for the management of preterm labor.

Published: July 2015

AbstractFamilial adenomatous polyposis (FAP) is a colorectal cancer syndrome caused by a germline mutation inherited in an autosomal-dominant pattern with a 100% penetrance.Our detailed case report presents a history of a 55-year-old FAP female patient who had been under constant clinical observation for 30 years. The disease was diagnosed at the age of 22. The patient underwent restorative proctocolectomy with ileal pouch-anal anastomosis (PRC-IPAA). During our follow-up extra-colonic manifestations occurred such as a desmoidtumour, fundic gland polyps in the stomach and duodenal polyps also in the periampullary region. Apart from disease-related symptoms the patient manifested other complications such as small bowel adhesive obstruction, benign breast tumours, uterine myomas, cholelithiasisand thyroid nodules.Our analysis of the above case presents advantages of a long-term medical observation of a FAP patient carried out by a specialist surgical medical centre

Intensive research is to determine and confirm the genetic basis of this disease, which is believed may have a direct relationship with the reduced efficiency of DNA repair systems.The aim of this study was to determine the effect of APEX gene polymorphism Ile64Val on increasing the risk of colorectal cancer in the Polish population.Material and methods. The blood samples collected from 150 patients diagnosed with colon cancer was used. The control group consisted of 150 healthy subjects. Genotyping was performed by TaqMan method.Results. The results indicate that genotype Ile Val is associated with an increased risk of colorectal cancer (OR 2.069; 95% CI 1,205-3,552; p = 0.008).Conclusions. Based on these results, we conclude that the APEX gene polymorphism Ile64Val may be associated with an increased risk of colorectal cancer.

Abstract
In analysis of complex nuclear forensic samples containing lanthanides, actinides and matrix elements, rapid selective extraction of
Am/Cm for quantification is challenging, in particular due the difficult separation of Am/Cm from
lanthanides. Here we present a separation process for Am/Cm(III) which is achieved using a combination of AG1-X8
chromatography followed by Am/Cm extraction with a triazine ligand. The ligands tested in our process were
CyMe4-BTPhen, CyMe4-BTBP, CA-BTP and CA-BTPhen. Our process allows for purification and quantification of Am and Cm
(recoveries 80% – 100%) and other major actinides in < 2 d without the use of multiple columns or
thiocyanate. The process is unaffected by high level Ca(II)/Fe(III)/Al(III) (10 mg mL
–1) and
thus requires little pre-treatment of samples.
