Demineralized bone allograft fibers versus particulate in sinus augmentation: A double‐arm randomized controlled and histomorphometric study

Journal of Periodontology, EarlyView.
Abstract Background The primary aim of this study was to evaluate histologic wound healing of demineralized freeze‐dried bone allograft (DFDBA), in particulate (P) or fiber (F) form, in combination with deproteinized bovine bone mineral (DBBM) for maxillary sinus floor augmentation.

From nature to nanoscale: advances, challenges, and preclinical translation of nanofiber drug delivery systems containing plant‐derived active ingredients

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Since the early 1960s, nanotechnology has been a critical area of science, allowing for the development of sophisticated nanomaterials. Nanofibers, one of the most widely used nanotechnological drug delivery systems, have emerged as a highly versatile platform within modern pharmaceutical sciences.

Novel PTFE hollow fiber membrane fabricated by emulsion electrospinning and sintering for membrane distillation

Journal of Membrane Science, 2019
Polytetrafluoroethylene (PTFE) is an attractive membrane material due to its superior chemical resistance, thermal stability and strong hydrophobicity. However, PTFE hollow fiber membranes are challenging to produce by conventional technique due to the ...

Chitosan hollow fiber membranes

Biopolymers, 2003
AbstractChitosan hollow fibers were produced by wet spinning, taking advantage of the unique rheological properties of highly viscous chitosan solutions in acetic acid. The mechanical and separation properties of hollow fibers were tested. The mechanical properties were determined by measuring tensile force, tensile stress, elongation, and initial ...

Hollow fiber membrane oxygenator

Journal of Biomedical Materials Research, 1971
AbstractHollow fibers have been produced and evaluated for use as membrane oxygenators in an artificial heart device. Gas permeable capillaries now commercially available are unsuitable for this use because of: (1) low percent open cross‐sectional area, (2) large internal diameter, and (3) high cost.

Preparation and application of patterned hollow-fiber membranes to membrane bioreactor for wastewater treatment

Journal of Membrane Science, 2015
Hollow-fiber membranes have been widely used in membrane processes for water and wastewater treatments, but membrane fouling in commercialized hollow-fiber membranes still remains a challengeable task to be solved.

A Siliconized Hollow Fiber Membrane Oxygenator

ASAIO Journal, 2000
Most membrane oxygenators are built with microporous fibers known for plasma leakage in long-term use such as extracorporeal life support or extracorporeal membrane oxygenation. The current study was designed to evaluate the Quadrox oxygenator in which the fibers have been coated with silicone (Jostra).

Hydraulic permeability of hollow‐fiber membranes

Journal of Biomedical Materials Research, 1978
AbstractTwo experimental methods have been developed to characterize the pressure‐driven flow of a liquid through the walls of single hollow‐fiber membranes. In one method, the permeation rate is measured directly by following the air–water interface in a pressurized pipet connected to a hollow fiber which is sealed at one end.
