Aluminum and its compounds are common contaminants of water and food, as well as medications and cosmetics. The wide distribution of the element facilitates the demand for detailed studies of its biological and toxicological effects. This work aimed to evaluate the possible genotoxic and toxic activity resulting from in vivo and in vitro exposure to Al. For in vivo analysis, 40 Swiss mice were used, various concentrations of hydrated aluminum chloride were administered orally. They were analyzed for possible genic activity and metal cytotoxicity using a micronucleus test (MN), and for toxicity through histopathological evaluation of the extracted organs...

Nanoarchitectures of titania (TiO2) have been widely investigated for a number of medical applications including implants and drug delivery. Although titania is extensively used in the food, drug and cosmetic industries, biocompatibility of nanoscale titania is still under careful scrutiny due to the conflicting reports on its interaction with cellular matter. For an accurate insight, we performed in vitro studies on the response of human dermal fibroblast cells toward pristine titania nanotubes fabricated by anodic oxidation...

: Gold nanoparticles (AuNPs) are present in many man-made products and cosmetics, and are also used by the food and medical industries. Tight regulations regarding the use of mammalian animals for product testing can hamper the study of the specific interactions between engineered nanoparticles and biological systems. Invertebrate models, such as the nematode Caenorhabditis elegans (C. elegans), can offer alternative approaches during the early phases of nanoparticle discovery. Here, we thoroughly evaluated the biodistribution of 11-nm and 150-nm citrate-capped AuNPs in the model organism C...

The use of clay by humans for medicinal and wellness purposes is most probably as old as mankind. Within minerals, due to its ubiquitous occurrence in nature and easy availability, clay was the first to be used and is still used worldwide. Healing clays have been traditionally used by man for therapeutic, nutritional and skin care purposes, but they could impart some important health and skin care risks. For instance, clay particles could adsorb and make available for elimination or excretion any potential toxic elements or toxins being ingested or produced, but they could adsorb and make available for incorporation, through ingestion or through dermal absorption, toxic elements, e...

Having long artificial (acrylic) nails is a current fashion trend, and they are becoming an increasingly popular cosmetic enhancement. We believe that they can be a potential burn hazard to their unknowing users. We present the first reported case in medical literature of a woman whose acrylic nail ignited from a cigarette butt a short distance from the nail while she was taking the final puffs. She sustained a full thickness burn to her dominant left thumb, resulting in terminalisation. Acrylic nails are very flammable and, once ignited, they burn to completion, with the source of flame removed...

Cellulose producing bacterial strain was isolated from citrus fruit juice fungus. The isolated strain was identified as Gluconacetobacter sp. gel_SEA623-2 based on several morphological characteristics, biochemical tests, and 16S rRNA conducted. Culture conditions for bacterial cellulose production by SEA623-2 were screened in static trays. Conditions were extensively optimized by varying the kind of fruit juice, pH, sugar concentration, and temperature for maximum cellulose production. SEA623-2 has a high productive capacity in citrus processing medium, but not in other fruits...

Gingival hyperpigmentation and the condition known as gummy smile are very common dental cosmetic problems. Gingival hyperpigmentation arises due to the excess presence of melanin in certain regions of the gums. In the case of gummy smile, more than the required amount of gingival tissue is exposed upon smiling. An aesthetically pleasing smile should expose only a negligible amount of gingival tissue. Gummy smile and gingival hyperpigmentation can have detrimental effects on the aesthetic quality of a smile, and thereby a wide variety of treatment options must be taken into consideration depending patient outcome objectives...

Zebrafish phosvitin-derived peptide Pt5, consisting of the C-terminal 55 residues of phosvitin, has been shown to have an antimicrobial-immunomodulatory activity comparable to phosvitin. Here, we showed clearly that Pt5 had the capacity to inhibit tyrosinase (TYR) activity and melanin biosynthesis, and this inhibition was independent of cell proliferation and cytotoxic effects. Incubation of fluorescein isothiocyanate (FITC)-labeled Pt5 with B16F10 melanoma cells revealed that Pt5 was localized in the cytoplasm of the cells...

The measurement of soft-tissue firmness has many potential applications in medical practice. This study reports a user-friendly, novel device that is capable of measuring changes in soft-tissue firmness in a reproducible manner. The study reports the development of the equipment and how it has been applied to breast implant surgery. The device was tested for both intra- and inter-observer variability on an in vitro model, using a breast implant. Once reproducibility was confirmed, breast firmness was measured on a series of patients who underwent sub-fascial breast augmentation (n = 50) to examine how it varied post-operatively...

Herein, we report novel high internal phase emulsions and transparent oleogels that exhibit a hierarchical configuration by manipulating the spatial assembly of a natural small molecular-weight quillaja saponin for color performance. Quillaja saponin (QS) is a natural triterpenoid bidesmosidic from the soapbark tree (Quillaja saponaria Molina). Fairly monodispersed QS-coated nanodroplets (∼154 nm) were prepared using the ultrasonic emulsification strategy, and then used as block stabilizers for the fabrication of stable oil-in-water high internal phase emulsions (HIPEs, ϕ = 0...

Yves Saint James Aquino
The popularity of surgical modifications of race-typical features among Asian women has generated debates on the ethical implications of the practice. Focusing on blepharoplasty as a representative racial surgery, this article frames the ethical discussion by viewing Asian cosmetic surgery as an example of medicalization, which can be interpreted in two forms: treatment versus enhancement. In the treatment form, medicalization occurs by considering cosmetic surgery as remedy for pathologized Asian features; the pathologization usually occurs in reference to western features as the norm...

BACKGROUND: Body sculpting, or body contouring, is among the fastest growing areas in cosmetic dermatology. Cryolipolysis, or "fat freezing," was FDA-cleared (CoolSculpting System, ZELTIQ Aesthetics, Pleasanton, CA) initially in 2010 for fat removal of the anks, and subsequently received FDA-clearance for other anatomical locations. Over the past several years, there have been increasing published reports and physician discussion regarding paradoxical adipose hyperplasia (PAH) post-cryolipolysis, previously identified as a "rare" adverse effect...
