Wireless sensor networks (WSNs) play an important role in Cyber Physical Social Sensing (CPSS) systems. An eavesdropping attack is one of the most serious threats to WSNs since it is a prerequisite for other malicious attacks. In this paper, we propose a novel anti-eavesdropping mechanism by introducing friendly jammers to wireless sensor networks (WSNs). In particular, we establish a theoretical framework to evaluate the eavesdropping risk of WSNs with friendly jammers and that of WSNs without jammers. Our theoretical model takes into account various channel conditions such as the path loss and Rayleigh fading, the placement schemes of jammers and the power controlling schemes of jammers...

The possible existence of the same pattern of porto-caval connection in dogs having a single congenital portosystemic shunt (CPSS) and in dogs having multiple acquired portosystemic shunt (MAPSS) secondary to portal hypertension (PH) was evaluated. Retrospective evaluation of all CT examinations of patients having portosystemic shunt (PSS) was performed in a 4-year time period. All anomalous porto-caval connections were assessed for anatomical pattern and compared with published veterinary literature. Records of 25 dogs were reviewed...

Three-variable-three-level Box-Behnken design-response surface methodology (BBD-RSM) based on the single-factor experiments was used to optimize the extracting parameters of crude polysaccharides (CPSs) from the Capparis spinosa leaves (CSL) including extraction time (ETi, 60-120min), extraction temperature (ETe, 60-80°C), and the water/solid ratio (W/S, 6-16). The optimal process conditions in order to the highest yield (6.73%) of CSL-CPSs were 119.8min ETi, 72.84°C ETe, and 15.97:1W/S.Structure of polysaccharide extracted at the optimal operating point were identified by Fourier transform-infrared spectroscopy (FT-IR)...

BACKGROUND: There is a dearth of empirical evidence on the effectiveness of pharmacological and nonpharmacological treatments for adolescents with post-traumatic stress disorder (PTSD) in developing country settings. The primary aim of this study was to demonstrate that Prolonged Exposure Treatment for Adolescents (PE-A) and supportive counselling (SC) are implementable by nurses in a South African context. A secondary aim was to perform a preliminary analysis of the effectiveness of registered nurses delivering either PE-A or SC treatment to adolescents with PTSD...

We developed a bedside algorithm for individually adjusting the high-dose methotrexate (HDMTX) dose (5 g/m) given to patients with acute lymphoblastic leukemia at high risk for methotrexate toxicity. Data were reviewed for 8 patients receiving 21 cycles of HDMTX as per our algorithm. Eleven cycles began with 5 g/m, 10 cycles began with a preinfusion 20% to 25% dose reduction. Neither mean MTX AUC (2320.5±179.1 vs. 2080.4±161.7 μmol×h/L), mean Cpss (64.3±7.9 vs. 60.8±6.1 μM), nor toxicities were statistically different between groups...

The first chemical synthesis of the heptasaccharide repeating unit of type V group B Streptococcus capsular polysaccharide (CPS) by a preactivation-based one-pot [2 + 1 + 4] glycosylation strategy is described. The synthetic efficiency was further improved by using diol glycosyl acceptors for regio-/stereoselective glycosylation reactions. The synthetic target contains a free amino group at the reducing end, facilitating additional regioselective elaboration. The results should be useful for synthetic and biological studies of related CPSs...

AIM: Congenital portosistemic shunt (CPSS) is an uncommon condition that can cause serious complications such as encephalopathy and liver tumors at risk of malignant degeneration. Occlusion of the shunt by surgery or interventional radiology can prevent and even improve such complications. In some cases, liver transplantation is the only curative option. We describe our experience with this condition. PATIENTS AND METHODS: Between 1992 and 2013, eight children (four male and four female) were diagnosed with CPSS (four extrahepatic and four intrahepatic) in our center, of which seven were diagnosed after 2007...

The most important factor for cervical pedicle screw placement (CPS) is creating a sufficient medial angle. We aimed to know the medial angle of the inserted subaxial CPS during surgery using intraoperative AP X-rays. From March 2012 to September 2014, we performed posterior cervical fusions using CPS on 75 patients, including a total of 389 CPS insertions. Using preoperative CT scanning, we determined the θlat (i.e., an angle between a vertical line and a line to connect the planned entry point and the axial middle point of the pedicle) and θmed (i...

BACKGROUND: Congenital portosystemic shunts (CPSS) with intrahepatic portal vein (IHPV) hypoplasia or absence cause encephalopathy or pulmonary hypertension (PH). Acute shunt closure may result in postoperative portal hypertension. The aim of this study was to propose a surgical strategy according to the anatomical types of CPSS and IHPV. METHODS: Twenty-three CPSS patients were diagnosed from1990 to 2015. All patients were evaluated by computed tomography, angiography, and PV pressure monitoring under a shunt occlusion test...

The post-operative analgesic effects of firocoxib in ovariohysterectomized cats were observed. Twenty-four cats were divided into 3 groups: control (no medicine), firocoxib-1 (1 mg/kg/day) and firocoxib-3 (3 mg/kg/day). Colorado pain scale scores (CPSS), composite pain scores (CPS), and buccal mucosal bleeding times (BMBT) were recorded in blinded fashion before induction and 2, 5, 8, 24, 30, and 48 hours post-operation. The average post-operative CPSS (mean±SEM) from 2 to 48 hours post-operation in firocoxib-3 (0...

Clonal cytogenetic abnormalities are found in 20-30% of patients with chronic myelomonocytic leukemia (CMML), while gene mutations are present in >90% of cases. Patients with low risk cytogenetic features account for 80% of CMML cases and often fall into the low risk categories of CMML prognostic scoring systems, but the outcome differs considerably among them. We performed targeted deep sequencing of 83 myeloid-related genes in 56 CMML patients with low risk cytogenetic features or uninformative conventional cytogenetics (CC) at diagnosis, with the aim to identify the genetic characteristics of patients with a more aggressive disease...

Streptococcus suis serotype 9 is the most prevalent S. suis serotype in several European countries. In spite of its pathogenicity for pigs and increasing zoonotic potential, limited information is available on this serotype. Here we determined for the first time the chemical composition and structure of serotype 9 capsular polysaccharide (CPS), a major bacterial virulence factor and the antigen at the origin of S. suis classification into serotypes. Chemical and spectroscopic data gave the repeating unit sequence: [3)Glcol-6-P-3-[D-Gal(α1-2)]D-Gal(β1-3)D-Sug(β1-3)L-Rha(α1-)]n...

BACKGROUND: Pregnancy planning and timing may be associated with psychiatric illness, psychological distress and support during pregnancy. METHODS: We performed secondary analyses of a prospective cohort of 2654 pregnant women evaluating the impact of depression on preterm birth. We used multivariable logistic regression to test associations between pregnancy planning ("Was this pregnancy planned? Yes/No") and/or timing ("Do you think this is a good time for you to be pregnant?") with Composite International Diagnostic Interview generated psychiatric diagnoses and measures of psychological distress and support...

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm with variable clinical course. To predict the clinical outcome, we previously developed a CMML-specific prognostic scoring system (CPSS) based on clinical parameters and cytogenetics. In this work, we tested the hypothesis that accounting for gene mutations would further improve risk stratification of CMML patients. We therefore sequenced 38 genes to explore the role of somatic mutations in disease phenotype and clinical outcome...

BACKGROUND AND PURPOSE: Patients with large vessel occlusion strokes (LVOS) may be better served by direct transfer to endovascular capable centers avoiding hazardous delays between primary and comprehensive stroke centers. However, accurate stroke field triage remains challenging. We aimed to develop a simple field scale to identify LVOS. METHODS: The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) scale was based on items of the National Institutes of Health Stroke Scale (NIHSS) with higher predictive value for LVOS and tested in the Screening Technology and Outcomes Project in Stroke (STOPStroke) cohort, in which patients underwent computed tomographic angiography within the first 24 hours of stroke onset...

Capsular polysaccharides (CPSs) are major bacterial virulent determinants that facilitate host immune evasion. E. coli group1 K30CPS is noncovalently attached to bacterial surface by Wzi, a lectin. Intriguingly, structure based phylogenetic analysis indicates that Wzi falls into porin superfamily. Molecular dynamics (MD) simulations further shed light on dual role of Wzi as it also functions as a bidirectional passive water specific porin. Such a functional role of Wzi was not realized earlier, due to the occluded pore...
