Effect of Collagen Nanofibers and Silanization on the Interaction of HaCaT Keratinocytes and 3T3 Fibroblasts with Alumina Nanopores.

During wound healing, a complex cascade of cellular and molecular events occurs, which is governed by topographical and biochemical cues. Therefore, optimal tissue repair requires scaffold materials with versatile structural and biochemical features. Nanoporous anodic aluminum oxide (AAO) membranes exhibit good biocompatibility along with customizable nanotopography and antimicrobial properties, which has brought them into the focus of wound treatment.

Self-assembled fibrinogen nanofibers support fibroblast adhesion and prevent E. coli infiltration.

Fibrinogen nanofibers hold great potential for wound healing applications since they mimic the native blood clot architecture and offer important binding sites to support fibroblast adhesion and migration. Recently, we introduced a new method of salt-induced self-assembly to prepare nanofibrous fibrinogen scaffolds. Here, we present our results on the mechanical properties of these scaffolds and their interaction with 3T3 fibroblasts and E.

The power of informal cancer caregivers' writings: results from a thematic and narrative analysis.

Background: Cancer is a disease that disrupts not only the patient's life, but that of the entire family as well, from a care, organizational, and emotional perspective. Patients share their experience of illness frequently with their informal caregiver (IC), a partner, son/daughter, friend, volunteer, or any other person in the family or social network who offers to support them during their clinical journey. The purpose of this study was to investigate ICs' still unknown cancer experiences through the stories of IC participants in a Literary Artistic Competition the Centro di Riferimento Oncologico di Aviano (CRO) IRCSS organized, and understand the themes that emerged from their texts and hence, the power of expressive writing.

Teledentistry applications for mitigating risk and balancing the clinical schedule.

The upheaval of providers and their patients has led to many changes in the way people live and work. In addition to the changes in Personal Protective Equipment (PPE) guidelines, there has been evidence of rapid adoption of telehealth services. In April of 2020, the American Dental Association's Health Policy Institute released a report stating that 1 in 4 dentists nationally were utilizing teledentistry to perform limited evaluations.

Spatial patterning of nanofibrous collagen scaffolds modulates fibroblast morphology.

Current knowledge about cell-biomaterial interactions is often based on two-dimensional (2D) cell culture systems like protein-coated glass slides. However, such smooth surfaces cannot mimic the nanofibrous environment of the native extracellular matrix (ECM). It is therefore a major challenge to transfer the results from 2D surfaces to 3D protein scaffolds with biomimetic nanofiber architecture.
