Biofouling is one of the drawbacks restricting the industrial applications of membranes. In this study, different thicknesses of silver nanoparticles with proper adhesion were deposited on poly(vinylidenefluoride) (PVDF) and polyethersulfone (PES) surfaces by physical vapor deposition (PVD). The crystalline and structural properties of modified and pure membranes were investigated by carrying out X-ray diffraction (XRD) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). Scanning electron microscope (SEM) and atomic force microscopy (AFM) analyses were employed to examine the surface morphology and the bacteria anti-adhesion property of the membranes...

Pulmonary vascular disease (PVD) represents an underestimated and increasing clinical burden in the neonatal period, but also later in life, when exercise-tolerance is decreased. Animal models performing long-term follow-up after a perinatal insult are lacking. This study aimed to develop and characterize a neonatal swine model with hypoxia-induced PVD, during long-term follow-up after re-exposure to normoxia, and to investigate the exercise response in this model. Piglets were exposed to a normoxic (N=10) or hypoxic environment (N=9) for four weeks...

Broad cognitive difficulties have been reported in patients with peripheral vestibular deficit, especially in the domain of spatial cognition. Processing and manipulating numbers relies on the ability to use the inherent spatial features of numbers. It is thus conceivable that patients with acute peripheral vestibular deficit show impaired numerical cognition. Using the number Stroop task and a short math achievement test, we tested 20 patients with acute vestibular neuritis and 20 healthy, age-matched controls...

INTRODUCTION: Renal transplant experiences widespread success, but little is published regarding the postoperative complications. The Charlson Comorbidity Index (CCI) is a system of mortality risk assessment. Our purpose is to assess the 90-day postoperative complications after renal transplantation. The secondary objective is to clarify whether CCI predicts complications. We hypothesized increased CCI corresponds to worse complication on the Clavien scale. METHODS: This is a retrospective analysis of renal recipients at our institution (2011-2013), who were ≥18 years old and received complete follow up...

BACKGROUND: Few studies have addressed the value of combining computed tomography-derived pulmonary vasculature metrics for the diagnosis and haemodynamic evaluation of pulmonary arterial hypertension (PAH). MATERIALS AND METHODS: We measured three computed tomography parameters for the pulmonary artery, peripheral vessels, and pulmonary veins: the ratio of the diameter of the pulmonary artery to the aorta (PA/Ao), the cross-sectional area of small pulmonary vessels <5mm(2) as a percentage of total lung area (%CSA<5), and the diameter of the right inferior pulmonary vein (PVD)...

Unlike their descendants, mitochondria and plastids, bacteria do not have dedicated protein import systems. However, paradoxically, import of protein bacteriocins, the mechanisms of which are poorly understood, underpins competition among pathogenic and commensal bacteria alike. Here, using X-ray crystallography, isothermal titration calorimetry, confocal fluorescence microscopy, and in vivo photoactivatable cross-linking of stalled translocation intermediates, we demonstrate how the iron transporter FpvAI in the opportunistic pathogen Pseudomonas aeruginosa is hijacked to translocate the bacteriocin pyocin S2 (pyoS2) across the outer membrane (OM)...

Our previous work showed the cell adhesion molecule SAX-7 formed an elaborate pattern in epidermal cell, which instructs PVD dendrite branching. However, the molecular mechanism forming the SAX-7 pattern in the epidermis is not fully understood. Here, we report that the dynein light intermediate chain DLI-1, and the fusogen EFF-1 are required in epidermal cells to pattern SAX-7. While previous reports suggest these two molecules act cell-autonomously in PVD, our results showed the disorganized PVD dendritic arbors in these mutants are due to the abnormal SAX-7 localization patterns in epidermal cells...

OBJECTIVES: The purpose of this study was to review the institutional practice of surveillance transthoracic echocardiography (TTE) for diagnosing early prosthetic valve dysfunction (PVD). BACKGROUND: Bioprosthetic valve thrombosis (BPVT) is an important cause of PVD, and guidelines do not recommend routine TTE during the first 5 years after valve implantation. METHODS: The authors performed a retrospective case-control study of all suspected (imaging diagnosis) or confirmed (histopathological diagnosis) cases of BPVT from January 1997 through December 2016...

STUDY OBJECTIVE: There is significant overlap between the symptoms of patients presenting with retinal detachment (RD) and posterior vitreous detachment (PVD). Urgency to obtain consultation and treatment are dependent on the ability to accurately distinguish these two conditions. The objective of this study was to determine the ability of emergency physicians to differentiate RDs from PVDs using point-of-care (POC) ocular ultrasound. METHODS: Single blinded cross-sectional study at an academic medical center...

BACKGROUND: Symptomatic vitreomacular adhesion (sVMA) is a recognised cause of visual loss and by tradition has been managed by pars plana vitrectomy (PPV). A less invasive alternative to surgery in some people is enzymatic vitreolysis, using an intravitreal injection of ocriplasmin. OBJECTIVES: To assess the efficacy and safety of ocriplasmin compared to no treatment, sham or placebo for the treatment of sVMA. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 1), MEDLINE Ovid (1946 to 24 February 2017), Embase Ovid (1947 to 24 February 2017), PubMed (1946 to 24 February 2017), the ISRCTN registry (www...

The dendritic processes of nociceptive neurons transduce external signals into neurochemical cues that alert the organism to potentially damaging stimuli. The receptive field for each sensory neuron is defined by its dendritic arbor, but the mechanisms that shape dendritic architecture are incompletely understood. Using the model nociceptor, the PVD neuron in C. elegans, we determined that two types of PVD lateral branches project along the dorsal/ventral axis to generate the PVD dendritic arbor: (1) Pioneer dendrites that adhere to the epidermis, and (2) Commissural dendrites that fasciculate with circumferential motor neuron processes...

Evolutionary psychologists propose that humans evolved a first line of defense against pathogens: the behavioral immune system (BIS). The BIS is thought to be functionally flexible such that the likelihood and magnitude of BIS activation depends on the individual's perceived vulnerability to disease (PVD). Because conspecifics are sources of infection, the BIS has implications for affiliation. By priming and measuring chronic levels of PVD, we examined PVD's relation to affiliation in zero-acquaintance situations in the laboratory, online, and during speed-dating events...

UV and visible light photocatalytic composite Pt and Au-TiO2 coatings have been deposited on silicon and glass substrates at low temperature using a hybrid ECWR-PECVD/MS-PVD process. Methylene blue, stearic acid and sulfamethoxazole were used as dye, organic and antibiotic model pollutants respectively to demonstrate the efficiency of these nanocomposite coatings for water decontamination or self-cleaning surfaces applications. Raman investigations revealed the formation of anatase polymorph of TiO2 in all synthesised coatings with a shifting of the main vibrational mode peak to higher wavenumber in the case of Au-TiO2 coating, indicating an increase number of crystalline defects within this coating...
