EPS09s and EKS98s: Impact parameter dependent nPDF sets

In our recent study we have determined two new spatially dependent nuclear PDF (nPDF) sets, EPS09s and EKS98s. With these, the hard-process cross-sections can be calculated in different centrality classes consistently with the globally analyzed nPDFs for the first time. The sets were determined by exploiting the $A$-systematics of the globally fitted nPDF sets, EPS09 and EKS98. For the spatial dependence of the nPDFs we used a power series ansatz in the nuclear thickness function $T_A$. In this flash talk we introduce the framework, and present our NLO EPS09s-based predictions for the nuclear modification factor in four centrality classes for inclusive neutral pion production in p+Pb collisions at the LHC and for inclusive prompt photon production in d+Au collisions at RHIC at midrapidity.Comment: 4 pages, 4 figures, Contribution to the proceedings of the Quark Matter 2012, Washington D.C., August 12-18, 201

Modeling the Impact Parameter Dependence of the nPDFs With EKS98 and EPS09 Global Fits

So far the nuclear PDFs (nPDFs) in the global DGLAP fits have been taken to be spatially independent. In this work, using the $A$-dependence of the globally fitted sets EPS09 and EKS98, we have determined the spatial dependence of the nPDFs in terms of powers of the nuclear thickness functions. New spatially dependent nPDF sets EPS09s (NLO, LO, error sets) and EKS98s (LO) are released. As an application, we consider the nuclear modification factor $R_{dAu}^{\pi^0}$ at midrapidity for neutral pion production in deuteron-gold collisions at RHIC in NLO. Comparison with the PHENIX data in different centrality classes is also shown. In addition, predictions for the corresponding nuclear modification factor $R_{pPb}^{\pi^0}$ in proton-lead collisions at the LHC are discussed.Comment: 4 pages, 4 figures, Talk given at Hard Probes 2012, 27 May - 1 June, 2012, Cagliari (Sardinia, Italy).

Meat and bone meal as fertilizer for oats - From slaughter house waste to fertilizer

EU permitted in 2006 the use of meat bone meal(MBM) as fertilizer. MTT Agrifood Research Finland's Kannus conducted a field experiment from 2000 to 2003 with a supplement experiment in 2004. The fertilization effect was 24 % higher after MBM than after chemical fertilizers

Meat bone meal as nitrogen and phosphorus fertilizer

Meat bone meal (MBM) contains considerable amount of nutrients (~8 % N, ~ 5 % P and ~ 10 Ca). To quantify and qualify MBM use as an N and P fertilizers, two field experiments were done on spring barley and oat in 2000 and 2001

The Efficacy of a Posterior Approach to Surgical Correction for Neglected Idiopathic Scoliosis: A Comparative Analysis According to Health-Related Quality of Life, Pulmonary Function, Back Pain and Sexual Function

Background: This study aimed to evaluate the treatment outcomes of severe idiopathic scoliosis (IS) and hypothesized that surgical treatment would have a superior impact on the health-related quality of life (HRQoL), pulmonary function (PF), back pain, and sexual function. Methods: We retrospectively reviewed 195 consecutive patients with IS classified into severe (SG) and moderate groups (MG) with a minimum follow-up of two years. Results: The mean preoperative curve was 131° and 60° in the SG and MG, respectively. The mean preoperative flexibility in the bending films averaged between 22% in the SG and 41% in the MG. After definitive surgery, the main curve was corrected to 61° and 18° in the SG and MG, respectively. The mean preoperative thoracic kyphosis was 83° in the SG and 25° in the MG, which was corrected to 35° in the SG and 25° in the MG. At baseline, the percentage of predicted lung volume (FVC) was significantly lower in the SG than that in the MG (51.2% vs. 83%). The baseline percentage of the predicted FEV1 values was also significantly lower in the SG than in the MG (60.8% vs. 77%). During the two-year follow-up, the percentage of predicted FVC showed significant improvement in the SG (69.9%) (p < 0.001), and the percentage of predicted FEV1 values during the follow-up improved significantly in the SG (76.9%) (p < 0.001) compared with the MG (81%), with no statistical difference observed during the two-year follow-up. The SRS-22r showed a clinically and statistically significant improvement in the preoperative results to those of the final follow-up (p < 0.001). Conclusions: Surgical treatment of severe scoliosis can be safe. It provided a mean correction of the deformity for 59% of patients and significantly improved respiratory function, with the percentage of predicted forced expiratory volume in 1 s improving by 60% and the forced vital capacity improving by 50%, resulting in clinically and statistically significant improvements in the SRS-22r, HRQoL outcome scores, and back pain (reduced from 36% to 8%), as well as improved sexual function. The planned surgical treatment can achieve a very significant deformity correction with a minimal risk of complications. The surgical treatment has a superior impact on the quality of life patients with severe spinal deformities and significantly improves function in every sphere of life

Hospital admissions and surgical treatment of children with lower-limb deficiency in Finland

Background and Aims: There are no population-based studies about hospital admissions and need for surgical treatment of congenital lower-limb deficiencies. The aim is to assess the impact children with lower-limb deficiencies pose to national hospital level health-care system. Materials and Methods: A population-based study was conducted using the national Register of Congenital Malformations and Care Register for Health Care. All 185 live births with lower-limb deficiency (1993-2008) were included. Data on hospital care were collected until 31 December 2009 and compared to data on the whole pediatric population (0.9 million) live born in 1993-2008. Results: The whole pediatric population had annually on average 0.10 hospital admissions and the mean length of in-patient care of 0.3 days per child. The respective figures were 1.5 and 5.6 in terminal lower-limb amputations (n = 7), 1.1 and 3.9 in long-bone deficiencies (n = 53), 0.6 and 1.9 in foot deficiencies (n = 26) and 0.4 and 2.6 in toe deficiencies (n = 101). Orthopedic surgery was performed in 72% (5/7) of patients with terminal amputations, in 62% (33/53) of patients with long bone, in 58% (14/24) of patients with foot and in 25% (25/101) of patients in toe deficiencies. Half (54%) of all procedures were orthopedic operations. Conclusion: In congenital lower-limb deficiencies the need of hospital care and the number of orthopedic procedures is multiple-fold compared to whole pediatric population. The burden to the patient and to the families is markedly increased, especially in children with terminal amputations and long-bone deficiencies of lower limbs.Peer reviewe

HPLC-DAD and UHPLC/QTOF-MS Analysis of Polyphenols in Extracts of the African Species Combretum padoides, C. zeyheri and C. psidioides Related to Their Antimycobacterial Activity

Combretum padoides Engl. & Diels, C. psidioides Welv. and C. zeyheri Sond. are used for the treatment of infections and tuberculosis related symptoms in African traditional medicine. In order to verify these uses, extracts were screened for their growth inhibitory effects against M. smegmatis ATCC 14468. Ultra-high pressure liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC/QTOF-MS) and GC-MS were used to investigate the polyphenolic composition in the active extracts. The lowest minimum inhibitory concentration (MIC), 625 µg/mL, was shown by a methanol extract of the stem bark of C. psidioides. A butanol extract of C. psidioides gave large inhibition zone diameters (IZD 21 mm) and inhibited 84% of the mycobacterial growth at 312 µg/mL. Combretastatin B-2 and dihydrostilbene derivatives were present in the methanol extract of C. psidioides, whereas the butanol extract of this species contained punicalagin, corilagin, and sanguiin H-4. Methanol and butanol extracts of the stem bark of C. padoides gave large inhibition zone diameters (IZD 26.5 mm) and MIC values of 1250 and 2500 µg/mL, respectively. C. padoides contained an ellagitannin with a mass identical to punicalagin ([M-H]− 1083.0587) and a corilagin like derivative ([M-H]− 633.0750) as well as ellagic acid arabinoside and methyl ellagic acid xyloside. A butanol extract of the roots of C. zeyheri showed mild antimycobacterial activity and contained a gallotannin at m/z [M-H]− 647.0894 as the main compound along with punicalagin and three unknown ellagitannins at m/z [M-H]− 763.0788, 765.0566, and 817.4212. Our results indicate that the studied species of Combretum contain phenolic and polyphenolic compounds with possible potential as leads for antimycobacterial drugs or as adjuvants for conventional anti-TB drugs

Impact of Pregnancy on Loss of Deformity Correction After Pedicle Screw Instrumentation for Adolescent Idiopathic Scoliosis

OBJECTIVE: A retrospective multicenter comparative study was carried out to evaluate whether pregnancy leads to the loss of deformity correction (LOC) in female patients surgically treated for idiopathic scoliosis. METHODS: A total of 128 female patients who underwent segmental spinal instrumentation and fusion for adolescent idiopathic scoliosis (AIS) between 1999 and 2014 were reviewed. Of these patients, 62 became pregnant (surgery-pregnancy group [SPG]), whereas 66 did not (surgery-nonpregnancy [SNP] group). Radiographic parameters were analyzed before surgery, after surgery, before pregnancy, up to 1 year after delivery, and at final follow-up (FFU). Health-related quality of life was analyzed using the Scoliosis Research Society outcome questionnaire (SRS-22r). RESULTS: The mean age at the time of surgery was 16 years in both groups. The mean preoperative major curves were 65 degrees (standard deviation [SD], 12 degrees) versus 67 degrees (SD, 11 degrees), 18 degrees (SD, 9 degrees) versus 17 degrees (SD, 9 degrees) immediately after surgery, and 20 degrees (SD, 8 degrees) versus 20 degrees (SD, 8 degrees) at FFU in the SPG and SNP groups, respectively (P > 0.10 for all comparisons). The mean loss of correction was 3.5 degrees (SD, 3 degrees) in the SPG and 4.5 (SD, 3 degrees) for SNP groups, respectively (P = 0.379). The mean preoperative thoracic kyphosis (T5-T12) was 26.5 degrees (SD, 11.9 degrees) for SPG and 24.7 degrees (SD, 14.5 degrees) for SNP, after surgery 19.2 degrees (SD, 9.5 degrees) for SPG, 18.8 (SD, 8.9 degrees) for SNP and at FFU, 20.3 degrees (SD, 9 degrees) for SPG and 21.3 degrees (SD, 8.5 degrees) for SNP. CONCLUSIONS: Women who have undergone pedicle screw instrumentation and fusion who have had >= 1 pregnancies do not have curve progression or deterioration in the longer-term outcomes compared with patients who have not become pregnant.Peer reviewe
