Spondylodiscitis may arise primarily via hematogenous spread or direct inoculation of virulent organisms during spine surgery. To date, no comparative data investigating the differences between primary and postoperative spondylodiscitis is available. Thus, the purpose of this retrospective study was to investigate differences between these two etiologies. One hundred fifty-nine patients that were treated at our department were included in the retrospective analysis. The patients were categorized into two groups based on the etiology of spondylodiscitis: group NS, primary spondylodiscitis without prior spinal surgery; group S, spondylodiscitis following spinal surgery...

In addition to tears of the rotator cuff, isolated impingement syndrome of the shoulder is the most common diagnosis in shoulder disorders. This is of high relevance in orthopedic sports medicine. In fact, impingement of the shoulder is not the diagnosis but rather a symptom of a functional or even a structural pathology. Detailed knowledge about the different types of impingement and the underlying causes is essential to provide adequate treatment. Primarily, impingement of the shoulder should be treated nonoperatively...

BACKGROUND: Elucidating the patterns of the Atlantic Bluefin tuna [ABFT, Thunnus thynnus (Linnaeus, 1758)] population structure constitutes a challenging task of great importance. Most of the unique challenges stem from its biology, as well as the attributes of the marine realm in which it disperses. Accurate information is urgently needed for stock assessment, and the identification of critical features to the persistence and adaptation of populations in order to formulate and adopt effective strategies for ABFT conservation and management...

Facial paralysis is a rare complication of acute suppurative otitis media which requires early detection and appropriate care. We hereby report a case which we managed conservatively with good outcome. Following our experience and review of literature on the subject, antibiotic therapy and corticosteroid therapy, with or without myringotomy were found to be the first-line procedures. Surgery should be employed in case of acute or coalescent mastoiditis, suppurative complications and lack of clinical regression...

Poor uterine receptivity leads to implantation defects or failure. Identification of uterine molecules crucial to uterine receptivity and/or embryo implantation provides the opportunity to design a diagnostic screening toolkit for uterine receptivity or targeted drug discovery for treating implantation-based infertility. In this regard, gene-profiling studies performed in humans and rodents have identified numerous genes involved in the transcriptional regulation of uterine receptivity and embryo implantation...

BACKGROUND: We sought to quantitatively describe the fine-scale foraging behavior of northern resident killer whales (Orcinus orca), a population of fish-eating killer whales that feeds almost exclusively on Pacific salmon (Oncorhynchus spp.). To reconstruct the underwater movements of these specialist predators, we deployed 34 biologging Dtags on 32 individuals and collected high-resolution, three-dimensional accelerometry and acoustic data. We used the resulting dive paths to compare killer whale foraging behavior to the distributions of different salmonid prey species...

BACKGROUND: Riboflavin is the precursor of important redox cofactors such as flavin mononucleotide (FMN) and flavin adenine dinucleotide, required for several biological processes. Vibrio cholerae, a pathogenic bacterium responsible for the cholera disease, possesses the ability to biosynthesize de novo as well as to uptake riboflavin through the riboflavin biosynthetic pathway (RBP) and the RibN importer, respectively. The intra-organism relationship between riboflavin biosynthesis and uptake functions has not been studied...

Recent population declines to the high elevation western North America foundation species whitebark pine, have been driven by the synergistic effects of the invasive blister rust pathogen, mountain pine beetle (MPB), fire exclusion, and climate change. This has led to consideration for listing whitebark pine (WBP) as a threatened or endangered species under the Endangered Species Act, which has intensified interest in developing management strategies for maintaining and restoring the species. An important, but poorly studied, aspect of WBP restoration is the spatial variation in adaptive genetic variation and the potential of blister rust resistant strains to maintain viable populations in the future...

The CDPK-SnRK (calcium-dependent protein kinase/Snf1-related protein kinase) gene superfamily plays important roles in signaling pathways for disease resistance and various stress responses, as indicated by emerging evidence. In this study, we constructed comparative analyses of gene structure, retention, expansion, whole-genome duplication (WGD) and expression patterns of CDPK-SnRK genes in Brassica rapa and their evolution in plants. A total of 49 BrCPKs, 14 BrCRKs, 3 BrPPCKs, 5 BrPEPRKs, and 56 BrSnRKs were identified in B...

Understanding how drylands respond to ongoing environmental change is extremely important for global sustainability. Here we review how biotic attributes, climate, grazing pressure, land cover change and nitrogen deposition affect the functioning of drylands at multiple spatial scales. Our synthesis highlights the importance of biotic attributes (e.g. species richness) in maintaining fundamental ecosystem processes such as primary productivity, illustrate how N deposition and grazing pressure are impacting ecosystem functioning in drylands worldwide, and highlight the importance of the traits of woody species as drivers of their expansion in former grasslands...

The current study examines Americans' psychological responses to Osama bin Laden's death. We tracked changes in how different participants responded to dissimilar others from the night of bin Laden's death for five weeks. Liberal participants reported lower worldview defense (i.e., a defensive reaction to uphold one's cultural worldview) immediately after bin Laden's death but then returned to similar levels as their conservative counterparts over time. Conservative participants reported greater worldview defense during each point of the study and did not significantly change over time...

Reductive dissolution of iron oxyhydroxides and reduction of arsenic are often invoked as leading causes of high dissolved As levels in shallow groundwater of Bangladesh. The second of these assumptions is questioned here by comparing the behavior As and phosphate (P), a structural analogue for As (V) which also adsorbs strongly to Fe oxyhydroxides but is not subject to reduction. The first line of evidence is provided by a detailed groundwater time-series spanning two years for three wells in the 6-9 m depth range showing removal of As(III) from shallow groundwater during the monsoon without of loss of P...

This paper uses a divergence-conforming B-spline fluid discretization to address the long-standing issue of poor mass conservation in immersed methods for computational fluid-structure interaction (FSI) that represent the influence of the structure as a forcing term in the fluid subproblem. We focus, in particular, on the immersogeometric method developed in our earlier work, analyze its convergence for linear model problems, then apply it to FSI analysis of heart valves, using divergence-conforming B-splines to discretize the fluid subproblem...

Sexual dimorphisms fuel significant intraspecific variation and evolutionary diversification. Yet the developmental-genetic mechanisms underlying sex-specific development remain poorly understood. Here, we focus on the conserved sex-determination gene doublesex (dsx) and the mechanisms by which it mediates sex-specific development in a horned beetle species by combining systemic dsx knockdown, high-throughput sequencing of diverse tissues and a genome-wide analysis of Dsx-binding sites. We find that Dsx regulates sex-biased expression predominantly in males, that Dsx's target repertoires are highly sex- and tissue-specific and that Dsx can exercise its regulatory role via two distinct mechanisms: as a sex-specific modulator by regulating strictly sex-specific targets, or as a switch by regulating the same genes in males and females in opposite directions...

Endoglucanases are key enzymes in the degradation of cellulose, the most abundant polymer on Earth. The aim of this work was to perform the biochemical and biophysical characterization of CelE2, a soil metagenome derived endoglucanase. CelE2 harbors a conserved domain from glycoside hydrolase family 5 (GH5) and a C-terminal domain with identity to Calx-beta domains. The recombinant CelE2 displayed preference for hydrolysis of oat beta-glucan, followed by lichenan and carboxymethyl cellulose. Optimum values of enzymatic activity were observed at 45°C and pH 5...

Lysozymes as an important immune factor, play vital roles in innate immune response against pathogen infection. In the present study, one c-type and g-type lysozymes were identified from Chinese giant salamander (Andrias davidianus). They shared highly conserved structural features with lysozymes from other species. Spatial expression analysis revealed that AdlysC transcript was most abundant in liver and stomach, and least in muscle and brain. In contrast, the expression level of AdlysG was most abundant in liver and least in muscle and skin...

The nuclear envelope (NE), a structural element of fundamental importance for the cell, is the first barrier that meets a virus in the early stages of viral maturation. Therefore, in order to allow the passage of nucleocapsids, viruses are known to modulate the architecture of the nuclear membrane to permit a proficient viral infection. Epstein-Barr Virus (EBV), a pathogen from Herpesvirus family, possesses two well conserved proteins, BFRF1 and BFLF2, which together form the heterodimeric nuclear egress complex (NEC) that is involved in the early steps of nuclear egress...

Intracavernous internal carotid artery (ICICA) aneurysm secondary to pituitary infection is exceedingly rare. We report an unusual case of a 63-year-old man who presented with acute left blepharoptosis and imaging findings of a pituitary infection. Interestingly, sudden onset of right blepharoptosis occurred after anti-infective therapy for ten days. Digital subtraction angiography revealed a right ICICA aneurysm. After six months of follow-up visits, enlargement of the ICICA aneurysm was observed, and the endovascular technique of a low-profile visualized intraluminal support (LVIS) stent combined with five detachable coils was successfully performed to treat the ICICA aneurysm with preservation of the internal carotid artery...
