Abstract
A meta-analysis was performed to determine the type, incidence and risks of dermatological toxicities associated with the multikinase inhibitor sorafenib. A literature search was performed using the electronic databases PubMed and EMBASE, and conference abstracts published by the American Society of Clinical Oncology. Eligible studies included prospective phase II or III clinical trials, and expanded-access programmes (i.e. outside a clinical trial) of patients with solid tumours assigned sorafenib at a starting dose of 400 mg twice daily. The overall incidences and risk ratios of dermatological toxicities associated with sorafenib were analysed. For patients assigned sorafenib, the overall incidence of all-grade rash/desquamation was 35.4% (95% CI 0.29-0.43), hand-foot skin reaction (HFSR) 39.0% (95% CI 0.32-0.47), alopecia 25.5% (95% CI 0.18-0.35), pruritus 14.0% (95% CI 0.10-0.20) and dry skin 14.1% (95% CI 0.10-0.20). High-grade rash/desquamation events occurred in 5.0% (95% CI 0.04-0.07), HFSR in 9.0% (95% CI 0.082-0.098), alopecia in 4/1793, pruritus in 2/1265 and dry skin in 0/1689 of patients assigned sorafenib. Meta-analysis of risk ratio showed that sorafenib was associated with a significantly increased risk of rash/desquamation [risk ratio (RR) 2.73; 95% CI 1.66-4.49)], HFSR (RR 7.50; 95% CI 3.90-14.40) and alopecia (RR 7.55; 95% CI 5.26-10.84) in patients with solid tumours, but risk of pruritus (RR 1.80; 95% CI 0.77-4.22) or dry skin (RR 2.18; 95% CI 0.88-5.40) was not increased. In conclusion, the most frequent dermatological toxicities associated with sorafenib were HFSR, rash/desquamation, alopecia, pruritus and dry skin. There was a significantly increased risk of HFSR, rash/desquamation and alopecia with sorafenib compared with placebo. Skin toxicities were mainly mild or moderate in severity. Appropriate prevention and management are recommended.

Abstract
Adult zebrafish, by virtue of exhibiting spontaneous recovery after spinal lesion, have evolved into a paradigmatic vertebrate model system to identify novel genes vital for successful regeneration after spinal cord injury. Due to a remarkable level of conservation between zebrafish and human genomes, such genes, once identified, could point to possibilities for addressing the multiple issues on how to deal with functional recovery after spinal cord injury in humans. In the current study, the extracellular matrix glycoprotein tenascin-C was studied in the zebrafish spinal cord injury model to assess the often disparate functions of this multidomain molecule under in vivo conditions. This in vivo study was deemed necessary since in vitro studies had shown discrepant functional effects on neurite outgrowth: tenascin-C inhibits neurite outgrowth when presented as a molecular barrier adjacent to a conducive substrate, but enhances neurite outgrowth when presented as a uniform substrate. Thus, our current study addresses the question as to which of these features prevails in vivo: whether tenascin-C reduces or enhances axonal regrowth after injury in a well accepted vertebrate model of spinal cord injury. We show upregulation of tenascin-C expression in regenerating neurons of the nucleus of median longitudinal fascicle (NMLF) in the brainstem and spinal motoneurons. Inhibition of tenascin-C expression by antisense oligonucleotide (morpholino) resulted in impaired locomotor recovery, reduced regrowth of axons from brainstem neurons and reduced synapse formation by the regrowing brainstem axons on spinal motoneurons, all vital indicators of regeneration. Our results thus point to an advantageous role of tenascin-C in promoting spinal cord regeneration, by promoting axonal regrowth and synapse formation in the spinal cord caudal to the lesion site after injury.

Abstract
Levels of urinary dialkylphosphates (DAPs) are currently used as a biomarker of human exposure to organophosphorus insecticides (OPs). It is known that OPs degrade on food commodities to DAPs at levels that approach or exceed those of the parent OP. However, little has been reported on the extent of DAP absorption, distribution, metabolism and excretion. The metabolic stability of O,O-dimethylphosphate (DMP) was assessed using pooled human and rat hepatic microsomes. Time-course samples were collected over 2 h and analyzed by LC-MS/MS. It was found that DMP was not metabolized by rat or pooled human hepatic microsomes. Male Sprague-Dawley rats were administered DMP at 20 mg kg(-1) via oral gavage and i.v. injection. Time-course plasma and urine samples were collected and analyzed by LC-MS/MS. DMP oral bioavailability was found to be 107 ± 39% and the amount of orally administered dose recovered in the urine was 30 ± 9.9% by 48 h. The in vitro metabolic stability, high bioavailability and extent of DMP urinary excretion following oral exposure in a rat model suggests that measurement of DMP as a biomarker of OP exposure may lead to overestimation of human exposure.

Abstract
As a transcriptional regulatory gene of the SIX family, SIX6 (also known as OPTX2, SIX9), probably affects pituitary development and secretion of hormones, suggesting that this gene is a potential candidate gene for studying association with growth trait in animals. Therefore, this study is first of all focused on detecting sequence variations in a bovine SIX6 gene and on its effects on growth traits in 1087 cattle from five Chinese cattle breeds using DNA sequencing and HhaI-ACRS-PCR methods. Herein, a novel mutation (NC_007308: g 2015T > C) in the TGA stop-codon of a bovine SIX6 gene was found, which leads to an ORF shift and extension of the encoded protein for four amino acids (Arg223-Gln224-Arg225-Val226). The frequency of allele "C" varied from 0.255 (Chinese Holsteins) to 0.614 (Hasake). They all were in the Hardy-Weinberg equilibrium except Jiaxian Red and Hasake cattle. Using amino acid sequence alignment and online prediction software, a new helix in the C-terminal domain of the mutated bovine SIX6 protein was revealed, which possibly affects pituitary development and hormone secretion. So, relationship analysis between this polymorphism and growth traits in the Nanyang breed was carried out based on a proper linear model. Although no statistically significant associations were observed (P > 0.05), the presented work preliminarily demonstrated a novel mutation in the TGA stop-codon which extends the spectrum of genetic variations of the bovine SIX6 gene and might be of interest in terms of its association with other biophysical and biochemical indexes.

Abstract
To characterize the properties of eu- and heterochromatic regions in Citrus species, the chromosomal distribution of different histone H3 marks, DNA methylation sites (5mC) and 45S ribosomal DNA sites were determined for C. clementina, C. paradisi, C. sinensis, and for the hybrid Ortanique C. reticulata × C. sinensis. Our data show that in the relatively small genomes of investigated Citrus species (genome size ranges from 378-400 Mbp) the euchromatin is characterized by histone H3 lysine 4 mono-, di- and trimethylation (H3K4me1/ 2/3) and histone H3 lysine 9 trimethylation (H3K9me3). In contrast, histone H3 lysine 9 mono- and dimethylation (H3K9me1/2), histone H3 lysine 27 mono-, di- and trimethylation (H3K27me1/2/3) as well as 5-methylcytosine (5mC) were enriched at certain heterochromatin fractions. Whereas H3K9me1/2 and H3K27me1 were preferentially enriched at the chromomycin A(3)-bright (CMA(+)) heterochromatin, H3K27me2/3 showed a higher accumulation at the DAPI brightly-stained heterochromatin. 5mC signals were associated with most of the CMA(+) areas as well as with the DAPI strongly-stained heterochromatin fraction. Therefore, extensive methylation of DNA as well as of H3K9me1/2 and H3K27me1/2/3, and depletion of H3K4me1/2/3 and H3K9me3 appear to be specific features of heterochromatin in Citrus. Transcriptionally active decondensed 45S rDNA sites were found DNA hypomethylated, while the silenced condensed sites were strongly 5mC methylated. Although the number of chromosomal 45S rDNA sites differed between the species, the number of transcriptionally active rDNA sites remains constant.

Abstract
Phytase is involved in many physiological activities in plants including phosphorus metabolism and stress response. The effects of arsenic on phytase activities in arsenic-hyperaccumulator Pteris vittata were determined. Two arsenic-sensitive ferns (Pteris ensiformis and Nephrolepis exaltata) were included for comparison purpose. Fern phytase was extracted with Tris-HCl buffer (pH 7.6) followed by ammonium sulfate partial purification to characterize its properties and arsenic stress responses. The phytase showed an optimum pH of 5.0 and temperature of 40 °C except for P. vittata with 40-70 °C. Phytase from P. vittata was the first plant-phytase showing high heat resistance with no loss of activity by heating it at 70 °C, which may have application in feed industry. Phytase activity was inhibited by arsenate but not by arsenite. The fact that P. vittata phytase was the most heat-tolerant (40-70 °C) and had the highest resistance to arsenate among the three ferns suggest that phytase may play a role in arsenic detoxification and arsenic hyperaccumulation in P. vittata.

Abstract
OBJECTIVE This descriptive study assessed the rate and costs of surgical procedures among newly diagnosed endometriosis patients. METHODS Utilizing the Medstat MarketScan database, commercially insured women aged 18-45 with endometriosis newly diagnosed during 2006-2007 were identified. Each endometriosis patient was matched to four women without endometriosis (population controls) based on age and region of residence. Surgical procedures received during the 12 months post-diagnosis were assessed. Costs of surgical procedures were the amount paid by the insurance companies. RESULTS This study identified 15,891 women with newly diagnosed endometriosis and 63,564 population controls. More than 65% of endometriosis patients received an endometriosis-related surgical procedure within 1 year of the initial diagnosis. The most common procedure was therapeutic laparoscopy (31.6%), followed by abdominal hysterectomy (22.1%) and vaginal hysterectomy (6.8%). Prevalence and type of surgery performed varied by patient age, including a hysterectomy rate of approximately 16% in patients younger than 35 and 37% among patients aged 35-45 years. Average costs ranged from $4,289 (standard deviation [SD]: $3,313) for diagnostic laparoscopy to $11,397 (SD: $8,749) for abdominal hysterectomy. LIMITATIONS Diagnosis of endometriosis cannot be validated against medical records, and information on the severity of endometriosis-related symptoms is not available in administrative claims data. CONCLUSIONS Over 65% of patients had endometriosis-related surgical procedures, including hysterectomy, within 1 year of being diagnosed with endometriosis. The cost of surgical procedures related to endometriosis places a significant financial burden on the healthcare system.

Abstract
Revealing the thermodynamic driving force of protein-DNA interactions is crucial to the understanding of factors that dictate the properties and function of protein-DNA complexes. For the binding of DNA to DNA-wrapping proteins, such as the integration host factor (IHF), Record and co-workers proposed that the disruption of a large number of preexisting salt bridges is coupled with the binding process [Holbrook, J. A., et al. (2001) J. Mol. Biol. 310, 379]. To test this proposal, we have conducted explicit solvent MD simulations (multiple ∼25-50 ns trajectories for each salt concentration) to examine the behavior of charged residues in IHF, especially concerning their ability to form salt bridges at different salt concentrations. Of the 17 cationic residues noted by Record and co-workers, most are engaged in salt bridge interactions for a significant portion of the trajectories, especially in the absence of salt. This observation suggests that, from a structural point of view, their proposal is plausible. However, the complex behaviors of charged residues observed in the MD simulations also suggest that the unusual thermodynamic characteristics of IHF-DNA binding likely arise from the interplay between complex dynamics of charged residues both in and beyond the DNA binding site. Moreover, a comparison of MD simulations at different salt concentrations suggests that the strong dependence of the IHF-DNA binding enthalpy on salt concentration may not be due to a significant decrease in the number of stable salt bridges in apo IHF at high salt concentrations. In addition to the Hofmeister effects quantified in more recent studies of IHF-DNA binding, we recommend consideration of the variation of the enthalpy change of salt bridge disruption at different salt concentrations. Finally, the simulation study presented here explicitly highlights the fact that the electrostatic properties of DNA-binding proteins can be rather different in the apo and DNA-bound states, which has important implications for the design of robust methods for predicting DNA binding sites in proteins.

Abstract
Adult zebrafish have the ability to recover from spinal cord injury and exhibit re-growth of descending axons from the brainstem to the spinal cord. We performed gene expression analysis using microarray to find damage-induced genes after spinal cord injury, and found that Sox11b mRNA is up-regulated at 11 days after injury. However, the functional relevance of Sox11b for regeneration is not known. Here, we report that the up-regulation of Sox11b mRNA after spinal cord injury is mainly localized in ependymal cells lining the central canal and in newly differentiating neuronal precursors or immature neurons. Using an in vivo morpholino-based gene knockout approach, we demonstrate that Sox11b is essential for locomotor recovery after spinal cord injury. In the injured spinal cord, expression of the neural stem cell associated gene Nestin, and the proneural gene Ascl1a (Mash1a), which are involved in the self-renewal and cell fate specification of endogenous neural stem cells, respectively, is regulated by Sox11b. Our data indicate that Sox11b promotes neuronal determination of endogenous stem cells and regenerative neurogenesis following spinal cord injury in the adult zebrafish. Enhancing Sox11b expression to promote proliferation and neurogenic determination of endogenous neural stem cells after injury may be a promising strategy in restorative therapy after spinal cord injury in mammals.

Abstract
The concurrence of the intracranial multiple primary tumors (MPTs) consisting of acoustic neuroma (AN) and pituitary adenoma is very rare. Here, we report a 42-year-old female who presented with left AN associated with pituitary adenoma. A total of three such cases have been reported before and which also presented with left AN with pituitary adenoma. Recently, a new "field cancerization" model has been proposed, which could explain MPTs and is consistent with the pathogenesis of such cases. The model also indicates that when a pituitary tumor or AN is detected separately, we might consider the development of "expanding field" after oncological treatment especially after radiotherapy in order to prevent the second field tumor occurring.

Abstract
Abstract. The Nucleophosmin 1 (NPM1) gene encodes a multifunctional nucleolar phosphoprotein that has crucial roles in the control of different aspects of cell growth and homeostasis, such as ribosome biogenesis, centrosome duplication, cell cycle progression, apoptosis and cell differentiation (GRISENDI et al. 2006, NAOE et al. 2006). As mutants of NPM1 gene impact protein synthesis, NPM1 is an essential protein in mouse development and cell growth (MAGGI et al. 2008). The bovine NPM1 gene contains one exon and locates at chromosome 9. In previous work, the 12-bp deletion was detected in bovine NPM1 gene coding region. (HUANG et al. 2010). In this study, the coding region of bovine NPM1 gene has been scanned by PCR-SSCP, DNA sequencing and forced PCR-RFLP methods for SNPs in 1 032 individuals belonging to four Chinese cattle breeds. Association of six mutations of NPM1 gene with growth traits was analyzed.

Abstract
Improved understanding of year-to-year late-spring soil nitrate test (LSNT) variability could help make it more attractive to producers. We test the ability of the Root Zone Water Quality Model (RZWQM) to simulate watershed-scale variability due to the LSNT, and we use the optimized model to simulate long-term field N dynamics under related conditions. Autoregressive techniques and the automatic parameter calibration program PEST were used to show that RZWQM simulates significantly lower nitrate concentration in discharge from LSNT treatments compared with areas receiving fall N fertilizer applications within the tile-drained Walnut Creek, Iowa, watershed (>5 mg NL(-1) difference for the third year of the treatment, 1999). This result is similar to field-measured data from a paired watershed experiment. A statistical model we developed using RZWQM simulations from 1970 to 2005 shows that early-season precipitation and early-season temperature account for 90% of the interannual variation in LSNT-based fertilizer N rates. Long-term simulations with similar average N application rates for corn (Zea mays L.) (151 kg N ha(-1)) show annual average N loss in tile flow of 20.4, 22.2, and 27.3 kg N ha(-1) for LSNT, single spring, and single fall N applications. These results suggest that (i) RZWQM is a promising tool to accurately estimate the water quality effects of LSNT; (ii) the majority of N loss difference between LSNT and fall applications is because more N remains in the root zone for crop uptake; and (iii) year-to-year LSNT-based N rate differences are mainly due to variation in early-season precipitation and temperature.
