Surgical Treatment for Spinal Tuberculosis With Bilateral Paraspinal Abscess or Bilateral Psoas Abscess: One-stage Surgery

Study Design: This was a prospective study on the clinical outcomes of single-stage surgery for thoracic and lumbar spine tuberculosis patients with bilateral paraspinal or bilateral psoas abscesses. Objective: The aim of this study was to investigate the feasibility of, indications for, and clinical effects of single-stage posterior surgery for the treatment of thoracic and lumbar spinal tuberculosis with bilateral paraspinal or bilateral psoas abscesses. Summary of Background Data: An increasing number of articles have been published on the use of single-stage surgery for spinal tuberculosis; however, none of these articles have discussed the use of such surgery in patients with bilateral abscesses. Methods: Between January 2003 and January 2011, 41 patients with thoracic and lumbar spinal tuberculosis and bilateral paraspinal or bilateral psoas abscesses were treated with single-stage posterior surgery. All of the patients were treated preoperatively with 1–2 weeks of antituberculosis drugs. All patients were managed postoperatively with standard courses of chemotherapy with triple or quadruple antituberculosis drugs. The clinical symptoms, complications, and laboratory and image indicators were recorded. Results: There were no local recurrences except in one L3–L4 tuberculosis patient. Two patients presented with extraspinal tuberculosis in the third year. There were no incision complications. Bone fusion was observed 6 months after the operation. The erythrocyte sedimentation rate was normal at 3 weeks–3 months postoperatively. There were no internal fixation failures. The internal fixations in 6 young patients were removed after the spinal tuberculosis was cured. Conclusions: Single-stage posterior surgery with instrumentation results in less operative trauma and can be a suitable alternative for treating thoracic and lumbar tuberculosis with bilateral paraspinal or bilateral psoas abscesses.
Differential Treatment Response for Eating Disordered Patients With and Without a Comorbid Borderline Personality Diagnosis Using a Dialectical Behavior Therapy (DBT)-Informed Approach

Studies have reported conflicting findings regarding the impact on treatment for eating disorder patients comorbidly diagnosed with borderline personality disorder. The current investigation sought to investigate whether individuals diagnosed with an eating disorder vs. those comorbidly diagnosed with an eating disorder and borderline personality disorder differ on measures of eating disorders symptoms and/or general distress over the course of treatment. In light of the success of DBT in treating individuals diagnosed with borderline personality disorder, a group known to have considerable difficulties in regulating affect, the current study also sought to examine whether these two groups would differ on expectancies to regulate affect over the course of DBT-informed treatment. Results indicated that while a comorbid diagnosis of borderline personality disorder did not impact eating disorder treatment outcomes, those comorbidly diagnosed did present overall with higher levels of general distress and psychological disturbance. With respect to affect regulation, results indicated that at the beginning of treatment, eating disordered individuals who carried a comorbid diagnosis of BPD were significantly less able to regulate affect than patients without a comorbid borderline diagnosis. However, at the end of treatment there was no statistically significant difference between the two groups. The role of affect regulation in treating eating disordered individuals with a comorbid borderline personality disorder diagnosis is discussed.
Predicting Natural Neuroprotection in Marine Mammals: Environmental and Biological Factors Affecting the Vulnerability to Acoustically Mediated Tissue Trauma in Marine Species

Abstract : The primary goal of these studies is to investigate the relative vulnerability of marine mammals to acoustically mediated trauma from emboli formation. By evaluating key environmental, behavioral and physiological factors involved in the movement of gases at the whole animal and tissue levels we intend to identify factors contributing to lipid, nitrogen, and carbon dioxide gas mobilization, and concomitant tissue damage at depth. The results of this project will enable the development of environmentally sensitive schedules for oceanic acoustic activities by identifying those species most susceptible to tissue injury.
Systematic investigation of halogen bonding in protein-ligand interactions.

Halogen bonding (XB) refers to the noncovalent interaction of general structure DX···A between halogen-bearing compounds (DX: XB donor, where X=Cl, Br, I) and nucleophiles (A: XB acceptor). Since the first observation in cocrystal structures of 1,4-dioxane and Br2 by Hassel and Hvoslef in 1954, XB has been widely used in crystal engineering and solid-state supramolecular chemistry. The nature of the interaction and the underlying electronic prerequisite, the s hole in the XB donor, have been the subject of extensive theoretical studies. 7–9] Most recently, the attractive nature of XB between 1-iodoperfluoroalkanes and various donors has also been demonstrated and quantified in solution studies. Novel inhibitors of human Cathepsin L (hCatL) were discovered which bind covalently to the side chain of the catalytic Cys25 residue in the S1 pocket under formation of thioimidates, which are stabilized by the oxyanion hole of the protease. These ligands form hydrogen bonds to the backbone NH and C=O groups of Gly68 and Asp162, respectively, and fill the S2 and S3 pockets, thereby interacting with the enzyme through multiple lipophilic contacts. During the course of this research, we obtained an indication of an XB contact between a 4-chlorophenyl moiety of a ligand, whose binding affinity was enhanced by a factor of 13 compared to the unsubstituted phenyl derivative, and the backbone C=O group of Gly61 in the S3 pocket (Figure 1). This finding stimulated the prepa-
Failure to confirm a synergistic effect between the K-variant of the butyrylcholinesterase gene and the ε4 allele of the apolipoprotein gene in Japanese patients with Alzheimer’s disease

To confirm a synergistic effect between the polymorphic K variant of the butyrylcholinesterase (BChE-K) gene and the ε4 allele of the apolipoprotein E (APOE) gene in Alzheimer’s disease, the frequency of the BChE-K allele was re-examined in a large series of Japanese patients with Alzheimer’s disease and controls. Two hundred and three patients with Alzheimer’s disease and 288 age and sex matched controls were genotyped by polymerase chain reaction and restriction fragment length polymorphism for BChE-K and APOE. No changes were found in the frequency of BChE-K, either in the Alzheimer’s disease group as a whole (0.17v 0.14; p=0.36) or in early (0.16v 0.16; p=0.98) or late (0.17v 0.13; p=0.24) onset patients compared with age matched controls. The study failed to confirm the findings of a previous study which found a significantly higher incidence of BChE-K in patients with Alzheimer’s disease with APOE ε4 allele than in controls. In the Japanese population studied here, there was no association between BChE-K and Alzheimer’s disease, nor an interaction between BChE-K and APOE ε4 allele.
Pushing doors for modeling contexts with OWL DL - a case study

In this paper we present an integrated view for modeling and reasoning for context applications using OWL DL. In our case study, we describe a task driven approach to model typical situations as context concepts in an OWL DL ontology. At run-time OWL individuals form situation descriptions and by use of realization we recognise a certain context. We demonstrate the feasibility of our approach by performance measurements of available highly optimised description logics (DL) reasoners for OWL DL
Gene–environment interactions in Leber hereditary optic neuropathy

Leber hereditary optic neuropathy (LHON) is a genetic disorder primarily due to mutations of mitochondrial DNA (mtDNA). Environmental factors are thought to precipitate the visual failure and explain the marked incomplete penetrance of LHON, but previous small studies have failed to confirm this to be the case. LHON has no treatment, so identifying environmental triggers is the key to disease prevention, whilst potentially revealing new mechanisms amenable to therapeutic manipulation. To address this issue, we conducted a large, multicentre epidemiological study of 196 affected and 206 unaffected carriers from 125 LHON pedigrees known to harbour one of the three primary pathogenic mtDNA mutations: m.3460G>A, m.11778G>A and m.14484T>C. A comprehensive history of exposure to smoking, alcohol and other putative environmental insults was collected using a structured questionnaire. We identified a strong and consistent association between visual loss and smoking, independent of gender and alcohol intake, leading to a clinical penetrance of 93% in men who smoked. There was a trend towards increased visual failure with alcohol, but only with a heavy intake. Based on these findings, asymptomatic carriers of a LHON mtDNA mutation should be strongly advised not to smoke and to moderate their alcohol intake.
Purification of an Endogenous Digitalislike Factor From Human Plasma for Structural Analysis

In previous reports, we described the isolation and characterization of an endogenous digitalislike factor (EDLF). In this report, we describe a unique combination of bioassay and large-scale purification methodology that made possible the purification of sufficient quantities of this inhibitor of Na+,K+-ATPase for structural analysis. Using an initial XAD-2 extraction and preparative high-performance liquid chromatography followed by a batch enzyme affinity extraction and two subsequent semipreparative chromatographic steps, 300 1 of human plasma was processed, yielding 31 /tg (53 nmol) of pure EDLF and representing purification on a dry weight basis in excess of 0.6 billionfold. Four divergent pieces of evidence, including chromatographic, mass spectrometric, immunoreactive, and binding characteristics, suggested that the EDLF purified in the present study was either ouabain or an isomer of ouabain. This material may represent a plasma-borne, naturally occurring, selective, high-affinity ligand for the digitalis binding site that may play a significant role in the modulation of the sodium pump and thereby cellular electrolyte homeostasis in humans. {Hypertension 1991;17:923-929)
Shake-and-Bake Translation

Publisher Summary This chapter presents a novel approach to Machine Translation (MT), called Shake-and-Bake translation, which is based on the idea of grammars as systems of constraints. Furthermore, in this approach translation equivalence is stipulated among bags of basic expressions of the languages concerned as presented in monolingual lexicalist grammars. Equivalence is constrained by equating variables in the logical forms of equivalent signs, providing a clear semantic basis for the notion of translation equivalence, and by any other constraints the bilingual lexicographer sees fit to include. Finally, the approach allows for the target language expressions to combine freely during generation, providing trivial accounts of phenomena for which structure-based approaches postulate complex transfer, noncompositional grammars, or undecidable logical inferences.
Processing of Natural Sounds: Characterization of Multipeak Spectral Tuning in Human Auditory Cortex

We examine the mechanisms by which the human auditory cortex processes the frequency content of natural sounds. Through mathematical modeling of ultra-high field (7 T) functional magnetic resonance imaging responses to natural sounds, we derive frequency-tuning curves of cortical neuronal populations. With a data-driven analysis, we divide the auditory cortex into five spatially distributed clusters, each characterized by a spectral tuning profile. Beyond neuronal populations with simple single-peaked spectral tuning (grouped into two clusters), we observe that ∼60% of auditory populations are sensitive to multiple frequency bands. Specifically, we observe sensitivity to multiple frequency bands (1) at exactly one octave distance from each other, (2) at multiple harmonically related frequency intervals, and (3) with no apparent relationship to each other. We propose that beyond the well known cortical tonotopic organization, multipeaked spectral tuning amplifies selected combinations of frequency bands. Such selective amplification might serve to detect behaviorally relevant and complex sound features, aid in segregating auditory scenes, and explain prominent perceptual phenomena such as octave invariance.
The Anti-Apoptotic and Cardioprotective Effects of Salvianolic Acid A on Rat Cardiomyocytes following Ischemia/Reperfusion by DUSP-Mediated Regulation of the ERK1/2/JNK Pathway

The purpose of this study was to observe the effects of salvianolic acid A (SAA) pretreatment on the myocardium during ischemia/reperfusion (I/R) and to illuminate the interrelationships among dual specificity protein phosphatase (DUSP) 2/4/16, ERK1/2 and JNK pathways during myocardial I/R, with the ultimate goal of elucidating how SAA exerts cardioprotection against I/R injury (IRI). Wistar rats were divided into the following six groups: control group (CON), I/R group, SAA+I/R group, ERK1/2 inhibitor PD098059+I/R group (PD+I/R), PD+SAA+I/R group, and JNK inhibitor SP600125+I/R group (SP+I/R). The cardioprotective effects of SAA on the myocardium during I/R were investigated with a Langendorff device. Heart rate (HR), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), maximum rate of ventricular pressure rise and fall (±dp/dtmax), myocardial infarction areas (MIA), lactate dehydrogenase (LDH), and cardiomyocytes apoptosis were monitored. To determine the crosstalk betwee JNK and ERK1/2 via DUSP2/4/16 with SAA pretreatment, siRNA-DUSP2/4/16 were performed. The expression levels of Bcl-2, Bax, caspase 3, p-JNK, p-ERK1/2 and DUSP2/4/16 in cardiomyocytes were assayed by Western blot. Our results showed that LDH, MIA and cell apoptosis were decreased, and various parameters of heart function were improved by SAA pretreatment and SP application. In the I/R group, the expression levels of p-ERK1/2 and DUSP4/16 were not significantly different compared with the CON group, however, the protein expression levels of p-ERK1/2, Bcl-2 and DUSP4/16 were higher, while p-JNK, Bax, caspase 3 and DUSP2 levels were reduced among the SAA+I/R, PD+SAA+I/R and SP+I/R groups. The above indices were not significantly different between the SAA+I/R and SP+I/R groups. Compared with the SAA+I/R group, p-ERK1/2 was increased and p-JNK was decreased in the SAA+si-DUSP2+I/R, however, p-ERK was downregulated and p-JNK was upregulated in SAA+si-DUSP4+I/R group. SAA exerts an anti-apoptotic role against myocardial IRI by inhibiting DUSP2-mediated JNK dephosphorylation and activating DUSP4/16-mediated ERK1/2 phosphorylation.
Dizzy People Perform No Worse at a Motor Imagery Task Requiring Whole Body Mental Rotation; A Case-Control Comparison

We wanted to find out whether people who suffer from dizziness take longer than people who do not, to perform a motor imagery task that involves implicit whole body rotation. Our prediction was that people in the “dizzy” group would take longer at a left/right neck rotation judgment task but not a left/right hand judgment task, because actually performing the former, but not the latter, would exacerbate their dizziness. Secondly, we predicted that when dizzy participants responded to neck rotation images, responses would be greatest when images were in the upside down orientation; an orientation with greatest dizzy-provoking potential. To test this idea, we used a case-control comparison design. One hundred and eighteen participants who suffered from dizziness and 118 age, gender, arm pain, and neck pain-matched controls took part in the study. Participants undertook two motor imagery tasks; a left/right neck rotation judgment task and a left/right hand judgment task. The tasks were completed using the Recognise program; an online reaction time task program. Images of neck rotation were shown in four different orientations; 0°, 90°, 180°, and 270°. Participants were asked to respond to each “neck” image identifying it as either “right neck rotation” or a “left neck rotation,” or for hands, a right or a left hand. Results showed that participants in the “dizzy” group were slower than controls at both tasks (p = 0.015), but this was not related to task (p = 0.498). Similarly, “dizzy” participants were not proportionally worse at images of different orientations (p = 0.878). Our findings suggest impaired performance in dizzy people, an impairment that may be confined to motor imagery or may extend more generally.
Regulation of lipopolysaccharide‐induced inflammatory response and endotoxemia by β‐arrestins

β‐Arrestins are scaffolding proteins implicated as negative regulators of TLR4 signaling in macrophages and fibroblasts. Unexpectedly, we found that β‐arrestin‐1 (β‐arr‐1) and ‐2 knockout (KO) mice are protected from TLR4‐mediated endotoxic shock and lethality. To identify the potential mechanisms involved, we examined the plasma levels of inflammatory cytokines/chemokines in the wild‐type (WT) and β‐arr‐1 and ‐2 KO mice after lipopolysaccharide (LPS, a TLR4 ligand) injection. Consistent with lethality, LPS‐induced inflammatory cytokine levels in the plasma were markedly decreased in both β‐arr‐1 and ‐2 KO, compared to WT mice. To further explore the cellular mechanisms, we obtained splenocytes (separated into CD11b+ and CD11b− populations) from WT, β‐arr‐1, and ‐2 KO mice and examined the effect of LPS on cytokine production. Similar to the in vivo observations, LPS‐induced inflammatory cytokines were significantly blocked in both splenocyte populations from the β‐arr‐2 KO compared to the WT mice. This effect in the β‐arr‐1 KO mice, however, was restricted to the CD11b− splenocytes. Our studies further indicate that regulation of cytokine production by β‐arrestins is likely independent of MAPK and IκBα‐NFκB pathways. Our results, however, suggest that LPS‐induced chromatin modification is dependent on β‐arrestin levels and may be the underlying mechanistic basis for regulation of cytokine levels by β‐arrestins in vivo. Taken together, these results indicate that β‐arr‐1 and ‐2 mediate LPS‐induced cytokine secretion in a cell‐type specific manner and that both β‐arrestins have overlapping but non‐redundant roles in regulating inflammatory cytokine production and endotoxic shock in mice.

Effect of adhesive application on the shear bond strength using different cementing agents in molar and premolar attachments

Objectives: The purpose of the study was to evaluate the effect of adhesive application on the shear bond strength (SBS) of orthodontic brackets and tubes to acid-etched human enamel when using different cementing agents. Study Design: One hundred and sixty metal attachments (80 tubes and 80 brackets) were bonded to human third molars and premolars that were randomly divided into identical groups of four: Transbond XT (XT); Wave MV Flow (WF); APC Plus System (APC); and Fuji Ortho LC (LC). For each experimental group, half of the specimens were bonded in combination with Transbond XT adhesive. After 72 h, a SBS test was performed using a universal testing machine. Statistical analysis was performed using ANOVA with Bonferroni post hoc comparisons, χ2 tests, and linear regression modeling. Adhesive remnant index scores were determined for the teeth after failure. Representative tooth surfaces from each subgroup were assessed under SEM. Results: Considering that each cement was observed, each of them showed similar SBS when the adhesive system was applied as when the adhesive was not applied. By comparing all cements together, it was noted that if an adhesive is not applied, all cements have similar values. If an adhesive is applied, cement XT, WF, and APC showed significantly higher SBS values than LC did. The tubes showed higher SBS than the brackets did in cements XT and WF with or without an adhesive, as well as APC Plus with an adhesive. Conclusions: The use of an adhesive system in bonding brackets and tubes does not influence the SBS obtained, independently of the cement.
Prefrontal Cortex Glutamate Correlates with Mental Perspective-Taking

Background Dysfunctions in theory of mind and empathic abilities have been suggested as core symptoms in major psychiatric disorders including schizophrenia and autism. Since self monitoring, perspective taking and empathy have been linked to prefrontal (PFC) and anterior cingulate cortex (ACC) function, neurotransmitter variations in these areas may account for normal and pathological variations of these functions. Converging evidence indicates an essential role of glutamatergic neurotransmission in psychiatric diseases with pronounced deficits in empathy. However, the role of the glutamate system for different dimensions of empathy has not been investigated so far. Methodology/Principal Findings Absolute concentrations of cerebral glutamate in the ACC, left dorsolateral PFC and left hippocampus were determined by 3-tesla proton magnetic resonance spectroscopy (1H-MRS) in 17 healthy individuals. Three dimensions of empathy were estimated by a self-rating questionnaire, the Interpersonal Reactivity Index (IRI). Linear regression analysis showed that dorsolateral PFC glutamate concentration was predicted by IRI factor “perspective taking” (T = −2.710, p = 0.018; adjusted alpha-level of 0.017, Bonferroni) but not by “empathic concern” or “personal distress”. No significant relationship between IRI subscores and the glutamate levels in the ACC or left hippocampus was detected. Conclusions/Significance This is the first study to investigate the role of the glutamate system for dimensions of theory of mind and empathy. Results are in line with recent concepts that executive top-down control of behavior is mediated by prefrontal glutamatergic projections. This is a preliminary finding that needs a replication in an independent sample.
