Antiapoptotic effects of scutellarin on ultraviolet A-irradiated HaCaT human keratinocytes
Biomedical Dermatology - Tập 2 - Trang 1-8 - 2018
Mina Choi, Seeun Jeon
This study examines the cellular protective effects of scutellarin on HaCaT cells in which oxidative stress was induced by ultraviolet A (UVA). Cell viability and lipid peroxidation were measured using WST-1 and MDA assays, respectively. The changes in cell number in the sub-G1 phase were assessed using cell cycle analysis, and tailed DNA levels were measured using the comet assay to examine the d...... hiện toàn bộ
MMP expression alteration and MMP-1 production control by syringic acid via AP-1 mechanism
Biomedical Dermatology - Tập 2 - Trang 1-10 - 2018
Ji Young Ryu, Eun Ju Na
Syringic acid is a phenolic compound that can be produced through selective hydrolysis of eudesmic acid containing 20% sulfuric acid. The acid is obtained by breaking down components, such as anthocyanin and lignin acid, present in the oils of acai berries and other fruits. Recently, the anti-inflammatory, selective toxicity, anticancer, and antioxidant effects of syringic acid have been studied, ...... hiện toàn bộ
Antioxidants as stabilizers of UV filters: an example for the UV-B filter octylmethoxycinnamate
Biomedical Dermatology - Tập 3 - Trang 1-9 - 2019
Margarida Lorigo, Elisa Cairrao
Sunlight is one of the main harmful exogenous factors that induce the reactive oxygen species formation. The human skin is the first line of photoprotection against harmful exogenous factors, such as UV radiations. The topical application of sunscreens, containing UV-B filters, is widely used to protect against UV-induced damage. Octylmethoxycinnamate is the world’s most widely used UV-B filter in...... hiện toàn bộ
Assessment of bacterial carriage on the hands of primary school children in Calabar municipality, Nigeria
Biomedical Dermatology - Tập 2 - Trang 1-7 - 2018
Ofonime M. Ogba, Patience E. Asukwo, Iquo B. Otu-Bassey
Hand washing with soap and water is a good hand hygiene practice which reduces the chance of infection transmission through hand contact. This study was designed to determine the microbial hand carriage among nursery and primary school children in Calabar Metropolis and to assess the effect of hand washing in the reduction of bacterial hand carriage among these children. A total of 150 pupils aged...... hiện toàn bộ

Clinical application of a new hyaluronic acid filler based on its rheological properties and the anatomical site of injection
Biomedical Dermatology - Tập 2 - Trang 1-5 - 2018
Won Lee, Jeung-Hyun Yoon, Ik-Soo Koh, Wook Oh, Ki-Wook Kim, Eun-Jung Yang
Hyaluronic acid (HA) filler is the most commonly used filler for soft tissue augmentation. There are numerous commercially available HA fillers in the cosmetic market, and there are guidelines for each filler as determined by the manufacturing company. The successful use of injectable fillers requires an understanding of each option available so that the most appropriate form of hyaluronic acid ma...... hiện toàn bộ
Global prevalence of hidradenitis suppurativa and geographical variation—systematic review and meta-analysis
Biomedical Dermatology - Tập 4 - Trang 1-6 - 2020
Kevin Phan, Olivia Charlton, Saxon D. Smith
There is a significant variation in the reported prevalence of hidradenitis suppurativa (HS), ranging from 0.03–4%. We hypothesized that this significant variation may be due to different prevalence rates of HS according to geographical location as well as sex. We aimed to perform a meta-analysis to determine pooled overall prevalence of HS, prevalence stratified according to geographical region a...... hiện toàn bộ
Inhibitory effect of naringenin on LPS-induced skin senescence by SIRT1 regulation in HDFs
Biomedical Dermatology - Tập 2 - Trang 1-9 - 2018
Kye Hwa Lim, Gyu Ri Kim
This study aims to investigate the ability of naringenin to regulate the expression of nuclear factor-кB, the upper gene of lipopolysaccharide-induced SIRT1; regulate signal transduction in the extracellular matrix, which plays an important role in the dermis; and alter the matrix metalloproteinase 1 and matrix metalloproteinase 3 gene expression, therefore having suppressing effect on skin cell s...... hiện toàn bộ
