Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Selection-Based Learning: The Coevolution Of Internal And External Selection In High-Velocity Environments [PDF]

open access: yes, 2004
To understand the effects of selection on firm-level learning, this study synthesizes two contrasting views of evolution. Internal selection theorists view managers in multiproduct firms as the primary agents of evolutionary change because they decide ...

Intercept Probability Analysis of Cooperative Wireless Networks with Best Relay Selection in the Presence of Eavesdropping Attack

open access: yes, 2013
Due to the broadcast nature of wireless medium, wireless communication is extremely vulnerable to eavesdropping attack. Physical-layer security is emerging as a new paradigm to prevent the eavesdropper from interception by exploiting the physical ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

From suboptimal prey to optimal performance: selective breeding improves Orius laevigatus performance on a low-cost mite diet

open access: yesFrontiers in Insect Science
The mass production of the generalist predator Orius laevigatus currently relies on expensive factitious prey, such as Ephestia kuehniella eggs. While astigmatid mites offer a low-cost alternative, their use has been historically limited by a significant

ENGINEERING DESIGN: EICOSANE MICROCAPSULES SYNTHESIS AND APPLICATION IN POLYURETHANE FOAMS AIMING TO DIMINISH WHEELCHAIR CUSHION EFFECT ON SKIN TEMPERATURE [PDF]

open access: yesJournal of Engineering Science and Technology, 2016
Thermal comfort of wheelchairs still requires improvements, since users remain on the chair for as long as 12 h a day. Increased sweating makes the skin more susceptible to colonization by fungi and bacteria, and may cause pressure ulcers. In this sense,

SELECTION DIFFERENTIALS AND SELECTION COEFFICIENTS [PDF]

open access: yesGenetics, 1978
ABSTRACT Proof is offered that s ≃ ig for all forms of selection where fitness is a nondecreasing function of a normally distributed phenotype (called fitness potential); s is selection coefficient, i is standard selection differential, and g is standard differential effect of a locus genotype.
