Zhiwei Huang, Robert S Gurney, Tao Wang, Dan Liu
Superhydrophobic (SH) surfaces with self-cleaning photocatalytic properties have become an important research focus in recent years. In this work, we fabricated multifunctional and environmentally durable SH surfaces via a facile one-step reaction of octadecyl isocyanate (ODI) with TiO2 particles. The resulting films possess SH properties, facilitated by a combination of hydrophobic long alkyl chains and the hierarchical crystalline structure. Films can be prepared via spray or blade coating on a variety of hard and soft substrates, and function well when exposed to either air or oil...

Epidermal stem cells residing in the skin play an essential role in epidermal regeneration. When skin is injured, the stem cells are first activated to proliferate, and subsequently the progeny migrate and differentiate to regenerate the epidermis. Here, we demonstrate that the vitamin D receptor (VDR) is essential for these processes to occur. The requirement for VDR on epidermal stem cell function was revealed in conditional VDR knockout (cKO) mice, in which VDR was deleted from stem cells and progeny, and mice were maintained on a low calcium diet...

Short peptide hydrogels are attractive biomaterials but typically suffer from limited mechanical properties. Inclusion of other nanomaterials can serve the dual purpose of hydrogel reinforcement and of conferring additional physico-chemical properties ( e.g., self-healing, conductivity), as long as they do not hamper peptide self-assembly. In particular, nanocarbons are ideal candidates and their physico-chemical properties have demonstrated great potential in nanocarbon-polymer gel biomaterials for tissue engineering or drug delivery...

The first example of a smart crystalline material, the 2:1 cocrystal of probenecid and 4,4'-azopyridine, which responds reversibly to multiple external stimuli (heat, UV light, and mechanical pressure) by twisting, bending and elastic deformation without fracture is reported. This material is also able to self-heal on heating and cooling, thereby overcoming the main setbacks of molecular crystals for future applications as crystal actuators. The photo- and thermomechanical effects and self-healing capabilities of the material are rooted in reversible trans-cis isomerization of the azopyridine unit and crystal-to-crystal phase transition...

Epidermolysis bullosa is a rare blistering skin disorder that is challenging to manage because skin fragility and repeated wound healing cause itching, pain, limited mobility, and recurrent infections. Cannabidiol, an active cannabinoid found in cannabis, is postulated to have antiinflammatory and analgesic effects. We report 3 cases of self-initiated topical cannabidiol use in patients with epidermolysis bullosa in an observational study. One patient was weaned completely off oral opioid analgesics. All 3 reported faster wound healing, less blistering, and amelioration of pain with cannabidiol use...

Large-area stretchable electronics are critical for progress in wearable computing, soft robotics and inflatable structures. Recent efforts have focused on engineering electronics from soft materials-elastomers, polyelectrolyte gels and liquid metal. While these materials enable elastic compliance and deformability, they are vulnerable to tearing, puncture and other mechanical damage modes that cause electrical failure. Here, we introduce a material architecture for soft and highly deformable circuit interconnects that are electromechanically stable under typical loading conditions, while exhibiting uncompromising resilience to mechanical damage...

OBJECTIVES: Secondary caries at the tooth-restoration margins is a primary reason for restoration failure. Cracks at the margins lead to leakage which can trap bacteria, producing acids to cause caries. To date, there has been no report on developing an adhesive resin that has self-healing, antibacterial and remineralizing capabilities. The objectives of this study were to: (1) develop the first self-healing adhesive with antimicrobial and remineralizing capabilities, and (2) investigate the effects of incorporating microcapsules, dimethylaminohexadecyl methacrylate (DMAHDM) and nanoparticles of amorphous calcium phosphate (NACP) for the first time...

Scabies and pediculosis are common parasitic infestations of the skin and hair, manifesting with intense pruritus and effectively treated with modern medications. Because of the attached social stigma linking it with poverty and poor hygiene, patients will often attempt alternative folk-based remedies before confiding in their physicians. We conducted a comprehensive bibliographical study of historic folk literature and interviewed 70 individuals experienced in everyday application of folk medicine in order to categorize available remedies and provide a modern, scientific comment on their effectiveness and dangers...

Optogenetics offers unique, temporally precise control of neural activity in genetically targeted specific neurons that express light-sensitive opsin molecules. Three-dimensional (3D) delivery of optogenetics can be realized by co-injection of bacteriorhodopsin (HEBR) plasmid with a chitosan-based self-healing hydrogel with strong shear-thinning properties. The HEBR protein shows photoelectrical properties and can be used as an optical switch for cell activation. We optimize the shear force generated during the process of injection (∼100 Pa), which is transient because of the self-healing nature of the hydrogel...

THEORETICAL PRINCIPLES: Pediatric oncology nurses are particularly vulnerable to emotional distress. Responsible for the oversight of a child's care, these nurses sustain close interactions with multiple patients and families over time, many of whom are coping with life-limiting diagnoses. The world of pediatric oncology nurses is one where tragedy is routinely witnessed thus demanding self-care and healing across a continuum. PHENOMENON ADDRESSED: The aim of this article is to outline and review the emotional sequelae of pediatric oncology nurses' work and to suggest interventions to support well-being in light of prolonged caregiving...

Duchenne muscular dystrophy (DMD) is a severe muscle wasting disease due to the absence of the dystrophin protein from the muscle cell membrane which renders the muscle susceptible to continuous damage. In DMD patients, muscle weakness, together with cycles of degeneration/regeneration and replacement with non-contractile tissue, limit mobility and lifespan. Since the loss of dystrophin result in loss of polarity and a reduction in the number of self-renewing satellite cells, it is postulated that these patients could achieve an improved quality of life if delivered cells could restore satellite cell function...

It is still a challenge to achieve both excellent mechanical strength and biocompatibility in hydrogels. Here we exploited two interactions to form a novel biocompatible, slicing-resistant and self-healing hydrogel. One is the molecular host-guest recognition between a host (isocyanatoethyl acrylate-modified β-cyclodextrin, β-CD-AOI2) and a guest (2-(2-(2-(2-(Adamantyl-1-oxy)ethoxy)ethoxy) ethoxy)ethanol acrylate, A-TEG-Ad) to form novel "three-arm" host-guest supramolecules (HGSMs). Another is the covalent bonding between HGSMs (achieved by UV-initiated polymerization) to form a strong network in the hydrogel...

A new supramolecular hydrogel with superior self-healing and shape memory properties was synthesized via in-situ copolymerization of the adamantane-containing monomer N-adamantylacrylamide (Ad-AAm) and monomer acrylic acid (AAc) in the polycyclodextrin (PCD) aqueous solution, where PCD served as the polyfunctional physical cross-linker. The PCD-Ad hydrogels showed strength of 40 kPa with breaking strain of 600%, but small tensile loading-unloading hysteresis and residual deformation benefited from the reversible crosslinking structure...

Chitosan derivative-based self-healable hydrogels with enhanced mechanical properties are reported, which were prepared by polymerization of acrylic acid (AAc) in 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) solution. The PAAc/HACC hydrogels exhibit tensile fracture stress as high as 3.31 MPa and a Young's modulus of 2.53 MPa. They can maintain their original shape after 30 repeated compression cycles under various strain conditions, with a compression stress of more than 60 MPa at 99% strain...

Polyacrylamide-sodium carboxymethylcellulose (PMC) hybrid hydrogels reinforced with graphene oxide (GO) and/or cellulose nanocrystals (CNCs) were prepared via in situ free-radical polymerization. In this work, GO nanosheets were freshly synthesized by modified Hummer's method alongwith the aqueous suspension of CNCs by acid-hydrolysis. In addition, the effect of GO content (1.5 wt%) and CNCs (from 2.5 wt% to 10.0 wt%) was investigated in these quaternary hydrogels. The results showed good pseudo-plastic behavior, self-healing ability, mechanical performance, and shape-recovery behavior of the hybrid hydrogels reinforced with GO and CNCs content...

A polyurethane nanohybrid has been prepared through the in situ polymerization of an aliphatic diisocyanate, ester polyol and a chain extender in the presence of two-dimensional platelets. Polymerization within the platelet galleries helps to intercalate, generate diverse nanostructure and improve the nano to macro scale self-assembly, which leads to a significant enhancement in the toughness and thermal stability of the nanohybrid in comparison to pure polyurethane. The extensive interactions, the reason for property enhancement, between nanoplatelets and polymer chains are revealed through spectroscopic measurements and thermal studies...

A major research challenge is to develop therapeutics that assist with healing damaged tissues and organs because the human body has limited ability to restore the majority of these tissues and organs to their original state. Tissue engineering (TE) and regenerative medicine (RM) promises to offer efficient therapeutic biological strategies that use mesenchymal stem cells (MSCs). MSCs possess the capability for self-renewal, multilineage differentiation, and immunomodulatory properties that make them attractive for clinical applications...
