A major challenge of tissue engineering is to generate materials that combine bioactivity with stability in a form that captures the robust nature of native tissues. Here we describe a procedure to fabricate a novel hybrid extracellular matrix (ECM) - synthetic scaffold biomaterial by cell-mediated deposition of ECM within an electrospun fiber mat. Synthetic polymer fiber mats were fabricated using poly(desamino tyrosyl-tyrosine carbonate) (PDTEC) co-spun with poly(ethylene glycol) (PEG) used as a sacrificial polymer...

Chemical peeling is a widely used procedure in the management of acne and acne scars. It causes controlled destruction of a part of or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The most frequently used peeling agents are salicylic acid, glycolic acid, pyruvic acid, lactic acid, mandelic acid, Jessner solution, trichloroacetic acid, and phenol. The appropriate peel is chosen based on the patient's skin type, acne activity, and type of acne scars...

Lichen planus pigmentosus is a photodistributed dyschromia of unknown etiology described clinically as hyperpigmented gray-blue or brown-black macules or patches in a photodistributed pattern. Although there has been some debate, lichen planus pigmentosus is considered by many to be a separate diagnostic entity from ashy dermatosis or erythema dyschromicum perstans, which shares similar characteristics. Various treatment strategies have been applied to help resolve or improve the appearance of lichen planus pigmentosus lesions; however, an optimal treatment method is yet to be elucidated...

Importance: Despite their great potential, medium and deep trichloroacetic acid peels are underused in light-skinned patients and are rarely used in darker-skinned patients because of the widespread fear of pigmentary complications and scarring. This concern has led many physicians to opt for the use of lighter types of peels (glycolic acid peel, Jessner peel, etc) and different lasers and intense light technologies. Trichloroacetic acid peels have been described in numerous publications...

We developed a novel strategy for fabricating poly(3,4-ethylenedioxythiophene) (PEDOT) patterns on various substrates, including hydrogels, via sequential solution procedure without multistep chemical etching or lift-off processes. First, PEDOT nanothin films were prepared on a glass substrate by solution phase monomer casting and oxidative polymerization. As a second step, after UV-induced poly(ethylene glycol) (PEG) photolithography at the PEDOT/PEG interface through a photomask, the hydrogel was peeled away from the PEDOT-coated glass substrate to detach the UV-exposed PEDOT region, which left the UV nonexposed PEDOT region intact on the glass substrate, resulting in PEDOT patterns...

The standard management of acne vulgaris in Japan includes a combination of topical treatment with benzoyl peroxide (BPO) and BPO/clindamycin (CLDM), topical adapalene and systemic antimicrobials. However, the treatment of therapy-resistant complications such as postinflammatory hyperpigmentation (PIH), erosions with inflamed red papules and atrophic scars has not been established. We performed chemical peeling with glycolic acid and iontophoresis with ascorbyl 2-phosphate 6-palmitate and DL-α-tocopherol phosphate for the treatment of PIH, erosions with inflamed red papules and non-inflamed atrophic scars in 31 patients with acne vulgaris (mild to severe severity), and evaluated the efficacy and safety of these interventions...

A facile strategy is developed to construct an ultrasensitive pH triggered charge/size dual-rebound gene delivery system for efficient tumor treatment. The therapeutic gene is complexed by polyethylenimine (PEI) and poly-l-glutamate (PLG), further in situ tightened by aldehyde modified polyethylene glycol (PEG) via Schiff base reaction. The generated Schiff base bonds are stable in neutral pH but cleavable in tumor extracellular pH. This gene delivery system possesses following favorable properties: (1) the tunable gene delivery system is constructed by chemical bench-free "green" and fast process which is favored by clinician, (2) PEG cross-linking shields the surface positive charges and tightens the complex particles, leading to decreased cytotoxicity, improved stability, and prolonged circulation, (3) PEG shielding can be rapidly peeled off by acidic pH as soon as arriving tumors, (4) dual charge/size ultrasensitively rebounding to higher positive potential and bigger size enhances tumor cell uptake efficiency...

Superparamagnetic iron oxide nanoparticles (SPIONs) have the potential to be used as multimodal imaging and cancer therapy agents due to their excellent magnetism and ability to generate reactive oxygen species when exposed to light. We report the synthesis of highly biocompatible SPIONs through a facile green approach using fruit peel extracts as the biogenic reductant. This green synthesis protocol involves the stabilization of SPIONs through coordination of different phytochemicals. The SPIONs were functionalized with polyethylene glycol (PEG)-6000 and succinic acid and were extensively characterized by X-ray diffraction analysis, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy, Rutherford backscattering spectrometry, diffused reflectance spectroscopy, fluorescence emission, Fourier-transform infrared spectroscopy, ultraviolet-visible spectroscopy, and magnetization analysis...

BACKGROUND: Glycolic acid (GA) peel is one of the most versatile agents in the treatment of melasma. GA peeling alone or in combination with topical hypopigmenting agents has shown encouraging results. However, there is paucity of controlled trial demonstrating the efficacy of glycolic peel in conjunction with topical azelaic acid (AA). We therefore sought to highlight the efficacy and safety of this combination in melasma. OBJECTIVE: To assess the clinical efficacy, safety and reduction in melasma quality of life (MELASQOL) scores on combining serial GA peels with topical 20% AA cream in epidermal melasma...
