This work increases our understanding of the effect of plant source on the mechanical and morphological properties of lignin-based polyurethanes (PUs). Lignin is a polymer that is synthesized inside the plant cell wall and can be used as a polyol to synthesize PUs. The specific aromatic structure of the lignin is heavily reliant on the plant source from which it is extracted. These results show...
Pulsed-mode ultrasound (pUS) in combination with intravenously (IV) administered microbubbles (MBs) can enhance local drug delivery by temporarily enhancing capillary permeability. This study evaluates the use of epidermal growth factor receptor (EGFR)-targeting MBs after pUS treatment to enhance the effects of therapeutic-EGFR antibody delivery to glioma tumor cells in mice. Three animal group...
This paper studies the security and communication efficiency problem of a reconfigurable intelligent surface (RIS) assisted cognitive radio network, in which we proposed scheme where secrecy rate (SR) transmission are jointly considered. In specific, with help RIS, exploit green interference caused by secondary network to ensure physical layer primary network. By taking mutual between these two...
Its gradient along a streamline is “favorable” (∂pus/∂s) < 0 for y > b′ − x, and “adverse” (∂pus/∂s) > 0 for y < b′ − x. On the interface where ψ = 0 and r = b′θ/ sin θ, pus(ψ = 0) vanishes at x = b′/2 ahead of the source (θ ' 10π/27), and is always < 0 downstream of that point. Because the interface has favorable pressure gradient until θ = θf ' 13π/20, and adverse ∀θ > θf , it is convenient t...
STUDY OBJECTIVE To investigate the effects of streptokinase and deoxyribonuclease (DNase) on the viscosity of pus to assess whether the DNase in the old preparation of streptokinase-streptodornase used intrapleurally to treat empyema was contributing to easier drainage of pus compared with purified streptokinase. DESIGN In vitro measurement of pus viscosity. PATIENTS Pus from three patients...
BACKGROUND Pressure ulcers are common conditions among hospitalized patients and impose substantial burden on patients and their caregivers. To assess the knowledge and attitudes of health professionals towards PUs prevention. METHODS A cross-sectional study was performed in the rehabilitation hospital at King Fahad Medical City, Riyadh, Saudi Arabia in 2014. The study population consisted of...
