OBJECTIVES/HYPOTHESIS: Reconstruction of craniofacial cartilagenous defects are among the most challenging surgical procedures in facial plastic surgery. Bioengineered craniofacial cartilage holds immense potential to surpass current reconstructive options, but limitations to clinical translation exist. We endeavored to determine the viability of utilizing adipose-derived stem cell-chondrocyte co-culture and three-dimensional (3D) printing to produce 3D bioscaffolds for cartilage tissue engineering...

Design and synthesis of integrated, interconnected porous structures are critical to the development of high-performance supercapacitors. We develop a novel and facial synthesis technic to construct three-dimensional carbon-bubble foams with hierarchical pores geometry. The carbon-bubble foams are fabricated by conformally coating, via catalytic decomposition of ethanol, a layer of carbon coating onto the surfaces of pre-formed ZnO foams and then the removal of the ZnO template by a reduction-evaporation process...

Ting Lan, Yan Xiao, Li Tang, Michael R Hamblin, Rui Yin
BACKGROUND: Acne scarring is a common disfiguring sequela of acne vulgaris which can lead to serious psychosocial problems and have a negative effect on patients' quality of life. Although a variety of approaches can be used to treat atrophic acne scars, disadvantages such as long-healing time, dyspigmentation, infections, and prolonged erythema make these treatments unsatisfactory especially for Asians. Fractional micro-plasma radio-frequency is a novel technology that produces minor ablation to the epidermis to promote rapid re-epithelialization, while the radio-frequency evoked thermal effect can stimulate regeneration and remodeling of dermal fibroblasts...

Presented in this paper is an effective technique to acquire the three-dimensional (3D) digital images of the human face without the use of active lighting and artificial patterns. The technique is based on binocular stereo imaging and digital image correlation, and it includes two key steps: camera calibration and image matching. The camera calibration involves a pinhole model and a bundle-adjustment approach, and the governing equations of the 3D digitization process are described. For reliable pixel-to-pixel image matching, the skin pores and freckles or lentigines on the human face serve as the required pattern features to facilitate the process...

Patients with thick skin are a challenge in facial plastic surgery. Rhinoplasty is still the most frequently performed facial plastic procedure worldwide and it becomes very difficult to obtain optimal consistent results in these patients. A systematic presurgical skin evaluation is performed dividing skin into type I-III depending on the elasticity, oiliness, presence of skin alterations, size of skin pores, and laxity. Depending on the skin type, presurgical, surgical, and postsurgical management of the epidermis and dermis is defined...

BACKGROUND: Enlarged facial pores and changes in pore area are of concern for cosmetic reasons. To evaluate pores, measuring tools based on 3D methodology are used. Yet, these methods are limited by their measuring ranges. In this study, we performed pore analysis by measuring the whole face using 2D optical images. We further sought to understand how the pores of Korean women change with age. MATERIALS AND METHODS: One hundred sixteen Korean female subjects aged 20-60 years were recruited for this study...

Nd:YAG laser has been used extensively for its versatility in treating many common aesthetic problems, but numerous adverse effects are often complained by recipients of Nd:YAG laser. This study introduces the ANT1 soybean extract cream, which was formulated to alleviate adverse effects after laser therapy. This study explores whether ANT1 enhances the repair mechanism of the postlaser skin, decreases laser-induced complication, and shortens recovery time. The study also aims to pinpoint the ANT1 concentration that is most effective in improving the skin condition after Nd-YAG laser therapy...

BACKGROUND: A previously published work explored the diversity of some biophysical parameters (colour, elasticity, sebum production, skin micro relief….) of the skin of 1204 Indian women, differently aged, living in 4 Indian cities (Chennai, Delhi, Kolkata, Mumbai). The present work aimed at completing such research by focusing on possible gender-related differences in the same skin parameters, between Indian men and women living in the same Indian city (Mumbai). METHODS: 297 Indian men, differently aged (18-70y) were recruited in Mumbai, completing the panel of 303 women who were previously recruited in this same city...

The development of efficient, cost-effective and long-lived electro-catalyst is necessary for the realization of practically viable water-splitting systems. A trifunctional electrocatalyst for water splitting (hydrogen evolution, oxygen reduction and oxygen evolution reaction, HER/ORR/OER) was designed via eco-friendly and facial way. CoFe2 O4 nanoparticles embedded in nitrogen doped mesoporous carbon were prepared using chicken egg white/albumin after pyrolysis at different temperatures, 700, 800, 900 and 1000 °C...

Background: Skin microbiome varies from person to person due to a combination of various factors, including age, biogeography, sex, cosmetics and genetics. Many skin disorders appear to be related to the resident microflora, yet databases of facial skin microbiome of many biogeographies, including Thai, are limited. Methods: Metagenomics derived B-RISA and 16S rRNA gene sequencing was utilized to identify the culture-independent bacterial diversity on Thai male faces (cheek and forehead areas)...

More men are beginning to take advantage of opportunities to improve the health and appearance of their skin; however, the effectiveness of men's skincare regimens has not been well studied. The authors investigated the efficacy and tolerance of a twice-daily, three-step men's skincare regimen in improving skin appearance and reducing shave-related issues. Twenty-nine men who used a wet-shaving method completed a specific, three-step, twice-daily facial regimen-a Shave Cleanser, a Post-Shave Treatment, and Day Protection-in place of their usual routine for 4 weeks...

The microtechnology of controlling stimuli-responsive biomaterials at micrometer scale is crucial for biomedical applications. Here, we report bovine serum albumin (BSA)-based three-dimensional (3D) microstructures with tunable surface morphology and pH-responsive properties via two-photon polymerization microfabrication technology. The laser processing parameters, including laser power, scanning speed, and layer distance, are optimized for the fabrication of well-defined 3D BSA microstructures. The tunable morphology of BSA microstructures and a wide range of pH response corresponding to the swelling ratio of 1...

BACKGROUND: India is a large country (a subcontinent) of about 3.3 million km2 that covers large ranges in latitude and longitude. The last Indian census counted about 1.21 billion of inhabitants of many origins, creating a vast human diversity and skin types, the variability of which having been previously established. The present study aimed at deepening this knowledge through a set of biophysical measurements to describe, along the skin ageing process, the specificities of various Indian subjects living in different geographical locations...

BACKGROUND: Enlarged facial pores can be an early manifestation of skin aging and they are a common aesthetic concern for Asians. However, studies of improving the appearance of enlarged pores have been limited. OBJECTIVE: The authors aimed to study the application of CO2 fractional laser treatment in patients with enlarged facial pores. METHODS: A total of 32 patients with dilated facial pores completed 3 consecutive sessions of low energy level treatments with a fractional CO2 laser at 4-week intervals...

Facial neural edema is the pathophysiological base of Bell's palsy. The middle cranial fossa approach is used to relieve the oppression of facial nerve at its most narrow course in the facial canal. In this research, the authors mainly discussed the internal auditory canal segment of facial nerve, completely in the shadow of the bony structure, which is inconvenient for transmastoid decompression. Therefore, the objective was to explore the definite position of the fundus meatus acustici interni from internal acoustic pore...
