Notoginseng is a traditional herbal medicine widely used for medicinal therapy in Asia, as it contains numerous ginsenosides with pharmacological effects. In this study, we submitted Notoginseng stem-leaf (NGL) ginsenosides to an enzyme to create reaction the monomer products of ginsenoside C-Mx and then investigated the ability of ginsenoside C-Mx to protect the skin against ultraviolet B-induced injury in normal human dermal fibroblasts (NHDFs). Ginsenoside C-Mx alleviated UVB-induced intracellular reactive oxygen species (ROS), MMP-1, and IL-6 expression while accelerating TGF-β and procollagen type I secretion...

We synthesized and investigated the effects of a novel peptide B, RRFSLLRY as a novel PAR-2 antagonist. Peptide B decreased calcium levels in HaCat cells stimulated with trypsin and PAR-2 activator (SLIGKV) and cytokeratin 14 and PCNA was decreased by peptide B. Peptides B also reduced the expression of inflammatory cytokines such as TNF-α and interleukin-6. Significant increase of oxazolone-induced transepidermal water loss (TEWL) was decreased by the addition of peptide B in hairless mice. These findings suggest that the anti-inflammatory effect of peptide B is due to inhibition of PAR-2 signaling...

Cosmetic surgery entails various ethical issues, even more so in cases involving adolescent patients. Cosmetic surgeons need to take into account how modern societies consider physical appearance an essential component of everyday life, as well as the vulnerability of youths and adolescents. For that reason, it is imperative to thoroughly assess the psychological and emotional states, in addition to the motivations, of minor patients. That goal can be achieved through the use of the DAS-59, (the Derriford Appearance Scale)1 , an effective and dependable tool devised to evaluate the psychological difficulties and distress experienced by people living with problems of appearance...

Abdominal aortic aneurysms (AAAs) are a chronic vascular disease characterized by pathological luminal dilation. Aortic rupture is the fatal consequence of AAAs. Ginkgo biloba extracts (GBEs), a natural herb extract widely used as food supplements, drugs, and cosmetics, has been reported to suppress development of calcium chloride-induced AAAs in mice. Calcium chloride-induced AAAs do not rupture, while angiotensin II (AngII)-induced AAAs in mice have high rate of aortic rupture, implicating potentially different mechanisms from calcium chloride-induced AAAs...

Tin dioxide nanofibers (SnDNFs) are small fibers that have many applications. Tin dioxide nanofibers can be used in cosmetics, solar cells, toxic gas release sensors, and air pollution control. To date there have been few studies on the cytotoxicity of SnDNFs. The goal of this research is to determine if electrospun SnDNFs are toxic in a lung cancer cell line (A549). Considering the nano-scale size of the fibers, they can easily be inhaled and enter the pulmonary system and cause toxic effects in the lung. Occupational exposure to SnDNFs has been linked to pulmonary disease, making the A549 cell line important in this study...

Natural bioactive compounds isolated from aromatic plants have been studied for centuries due to their unique characteristics that carry great importance in food, pharmaceutical, and cosmetic industry. For instance, several beneficial activities have been attributed to some specific compounds found in Thymus such as anti-inflammatory, antioxidant, antimicrobial and antiseptic properties. Moreover, these compounds are classified as Generally Recognized as Safe (GRAS). Conventional extraction processes of these compounds and their derived forms from thyme leaves are well established, however, they present some important drawbacks such as long extraction time, low yield, high solvent consumption and unfavorable effect on thermolabile compounds...
