Campylobacter is the leading cause of foodborne human diarrhea worldwide. This microbe in the viable but non-culturable (VBNC) state can evade detection by routinely used culture-based methods and remain viable for extended periods of time. Bacteria in this dormancy state can resume their metabolic activity and virulence by resuscitation under favorable conditions, and subsequently cause infections. In this study, an assay combining loop-mediated isothermal amplification (LAMP) and propidium monoazide (PMA) treatment was developed for the detection and quantification of VBNC C...

Phosphatidylserine (PS) is involved in various cellular processes in yeast and animals. However, PS functions in plants remain unclear. In Arabidopsis, PS is relatively enriched in flower and root tissues, and the genetic disturbance of PS biosynthesis in PHOSPHATIDYLSERINE SYNTHASE1 (PSS1)/pss1 heterozygotes induces sporophytic and gametophytic defects during pollen maturation. This study functionally characterized PS in Arabidopsis roots and observed that pss1 seedlings exhibited a short-root phenotype by reducing the meristem size and cell elongation capacity...

The objective of the present study is to investigate the different effects on the oxygen transfer of fine-bubble aeration systems in saline water. Compared to tap water, oxygen transfer increases due to the inhibition of bubble coalescence. In Part I of the present study, we investigated in laboratory-scale experiments the effect of design of diffuser membrane. The objective of Part II is the assessment of effects of different salts, diffuser type and diffuser density. We measured the concentration of various salts (MgCl2 ; CaCl2 ; Na2 SO4 ; NaCl; KCl) above which coalescence is fully inhibited and oxygen transfer reaches its maximum (referred to as the critical coalescence concentration; CCC)...

A novel photocatalytic continuous system has been proposed for the treatment of tannery waste water, which has high levels of environmental pollutants. The purification process was performed by passing wastewater on a titanium dioxide (TiO2 )-coated surface, which is continuously activated by irradiation of ultraviolet light. To improve the yield of the process, ferric chloride (FeCl3 ) was used as a coagulation agent. The organic and inorganic compounds, as well as the microorganisms in the tannery wastewater media, were degraded through a photocatalytic process...

The construction of a highly sensitive and reproducible surface-enhanced Raman scattering (SERS) substrate is the key factor that restricts its practical application. In this paper, a three-dimensional (3D) SERS substrate based on ordered micropyramid array and silver nanoparticles (MPA/AgNPs 3D-SERS) was constructed using the roll-to-plate embossing technology and a hydrothermal method, which provided an efficient and low-cost preparation process for the SERS substrate. Using rhodamine 6G (R6G) as a probe molecule, the performance of an MPA/AgNP 3D-SERS substrate was studied in detail, whose minimum detection limit was 10-12 M and the enhancement factor was calculated as 8...

Detection of patients with intestinal colonization of carbapenem-resistant organisms (CRO), or more specifically carbapenemase-producing (CP) CRO, can prevent their transmission in healthcare facilities and aid with outbreak investigations. The objective of this work was to further develop and compare methods that combine selective culture and/or PCR to rapidly detect and recover CRO from fecal specimens. Molecularly characterized Gram-negative bacilli (n = 62) were used to spike fecal samples to establish limit of detection (LOD; n = 12), sensitivity (n = 28), and specificity (n= 21) for 3 methods to detect CP-CRO: direct MacConkey (MAC) plate and Xpert Carba-R (Cepheid) on growth, MAC broth and Carba-R testing of the broth, and direct testing by Carba-R...

Open reduction and pre-contoured locking plate fixation is a popular treatment option for displaced midshaft clavicle fracture. Lag screw and cerclage are 2 main intraoperative techniques to reduce and fix fragments. However, both lag screw and metallic cerclage have disadvantages. The doubled-suture Nice knot has been reported in many areas of orthopedic surgery for its effectiveness. This study aims to compare the outcomes of comminuted mid-shaft clavicle fractures reduced by Nice knots vs traditional techniques (lag screw or/and metallic cerclage) when bridged with pre-contoured locking plates...

We study the bending of a booklike system, comprising a stack of elastic plates coupled through friction. The behavior of this layered system is rich and nontrivial, with a nonadditive enhancement of the apparent stiffness and a significant hysteretic response. A dimension reduction procedure is employed to develop a centerline-based theory describing the stack as a nonlinear planar rod with internal shear. We consider the coupling between the nonlinear geometry and the elasticity of the stacked plates, treating the interlayer friction perturbatively...

Changes in trabecular micro-architecture are key to our understanding of osteoporosis. Previous work focusing on structure model index (SMI) measurements have concluded that disease progression entails a shift from plates to rods in trabecular bone, but SMI is heavily biased by bone volume fraction. As an alternative to SMI, we proposed the ellipsoid factor (EF) as a continuous measure of local trabecular shape between plate-like and rod-like extremes. We investigated the relationship between EF distributions, SMI and bone volume fraction of the trabecular geometry in a murine model of disuse osteoporosis as well as from human vertebrae of differing bone volume fraction...
