Patients received combined therapy of SOF (400 mg/day for patien...

Real-world cell phone radiofrequency electromagnetic field exposures.

In 2011 the International Agency for Research on Cancer classified radiofrequency electromagnetic fields (RF EMF) from cell phones as possibly carcinogenic to humans. The National Toxicology Program and the Ramazzini Institute have both reported that RF EMF exposures significantly increase gliomas and Schwannomas of the heart in rodent studies. Recent studies indicate that RF EMF exposures from cell phones have negative impacts on animal cells and cognitive and/or behavioral development in children. Case-co...

This study investigated the feasibility, acceptability, and potential efficacy of a 12-week cell phone support intervention to improve immunosuppressant medication adherence. A small sample (N = 8) of non-adherent adolescent and young adult transplant recipients, aged 15-20.5 years, was enrolled. Cell phone support consisted of short calls each weekday including medication reminders, discuss...

Estimating transmitted power density from mobile phone: an epidemiological pilot study with a software modified phone.

The aims of this study were to evaluate the weekly and annual cumulative radiofrequency-electromagnetic field (RF-EMF) exposure attributed to mobile phone (MP) use, and assess whether a novel app (Quanta Monitor™) could be employed in a small human sample to characterise the RF-EMF exposures associated with the use of MPs. Ten participants provided their two months' daily objective data on their MP exposures (i.e. transmitted and received power densities) attributed to different modes of MP usage such as...

Regulating hearing aid compatibility of cell phones: results from a national survey.

Accessibility of telecommunication technologies by people who are deaf or hard of hearing has been a critical issue since the invention of the telephone. As both telephone and hearing-aid technologies have evolved, finding compatible solutions has been an ongoing challenge. This paper uses the findings of a longitudinal study to examine the impact of Federal hearing-aid compatibility (HAC) regulations in resolving this problem. The study ran concurrently with the phase-in of Federal Communications Commissio...

How does self-esteem affect mobile phone addiction? The mediating role of social anxiety and interpersonal sensitivity.

Low self-esteem is an important factor influencing mobile phone addiction, which has been well documented. However, little research focused on the mechanism underlying the association between self-esteem and mobile phone addiction. We hypothesized that social anxiety and interpersonal sensitivity may mediate the relationship between self-esteem and mobile phone addiction. Six hundred and fifty three (353 girls among them) college students with the mean age of 19.94 (SD = 1.34) were recruited for the stu...

Hydrogels of agarose, and methacrylated gelatin and hyaluronic acid are more supportive for in vitro meniscus regeneration than three dimensional printed polycaprolactone scaffolds.

In this study, porcine fibrochondrocyte-seeded agarose, methacrylated gelatin (GelMA), methacrylated hyaluronic acid (MeHA) and GelMA-MeHA blend hydrogels, and 3D printed PCL scaffolds were tested under dynamic compression for potential meniscal regeneration in vitro. Cell-carrying hydrogels produced higher levels of extracellular matrix (ECM) components after a 35-day incubation than the 3D printed PCL. Cells on GelMA exhibited strong cell adhesion (evidenced with intense paxillin staining) and dendritic c...

Determination of Geometrical and Viscoelastic Properties of PLA/PHB Samples Made by Additive Manufacturing for Urethral Substitution.

Additive manufacturing has a great potential for creating hard tissue substitutes, such as bone and cartilage, or soft tissues, such as vascular and skin grafts. This study is a pilot study for 3D printing of a new material mixture potentially used as a tubular substitute for urethra replacement. This new mixture is a blend of polylactic acid (PLA) and polyhydroxybutyrate (PHB). The basic aspect that affects the 3D printing process is correct material preparation and setting of 3D printer parameters. Select...

Direct 3D printing of monolithic ion exchange adsorbers.

Monolithic adsorbers with anion exchange (AEX) properties have been 3D printed in an easy one-step process, i.e. not requiring post-functionalization to introduce the AEX ligands. The adsorber, 3D printed using a commercial digital light processing (DLP) printer, was obtained by copolymerisation of a bifunctional monomer bearing a positively charged quaternary amine as well as an acrylate group, with the biocompatible crosslinker polyethylene glycol diacrylate (PEGDA). To increase the surface area, polyethy...

EMSCs Build an All-in-One Niche via Cell-Cell Lipid Raft Assembly for Promoted Neuronal but Suppressed Astroglial Differentiation of Neural Stem Cells.

The therapeutic efficiency of allogenic/intrinsic neural stem cells (NSCs) after spinal cord injury is severely compromised because the hostile niche at the lesion site incurs massive astroglial but not neuronal differentiation of NSCs. Although many attempts are made to reconstruct a permissive niche for nerve regeneration, solely using a living cell material to build an all-in-one, multifunctional, permissive niche for promoting neuronal while inhibiting astroglial differentiation of NSCs is not reported....

Collective Cell Behavior in Mechanosensing of Substrate Thickness.

Extracellular matrix stiffness has a profound effect on the behavior of many cell types. Adherent cells apply contractile forces to the material on which they adhere and sense the resistance of the material to deformation-its stiffness. This is dependent on both the elastic modulus and the thickness of the material, with the corollary that single cells are able to sense underlying stiff materials through soft hydrogel materials at low (
