The transfer characteristics of Cd and Pb from soils to the edible parts of six vegetable species were calculated from plant and corresponding surface soil samples collected from the fields in Fujian Province, southeastern China. The soil-to-plant transfer factors (TF) calculated from both total and DTPA-extractable Cd and Pb in the soils decreased with(More)
While the mutagenic and carcinogenic properties of longwave UV light (UVA) are well established, mechanisms of UVA mutagenesis remain a matter of debate. To elucidate the mechanisms of mutation formation with UVA in human skin, we determined the spectra of UVA- and UVB-induced mutations in primary human fibroblasts. As with UVB, we found the majority of(More)
Major depressive disorder is a common neuropsychiatric disorder contributing to several socio-economic burdens including disability and suicide. As the underlying pathophysiology of major depressive disorder remains unclear, no objective test is yet available for aiding diagnosis or monitoring disease progression. To contribute to a better understanding of(More)
Ultraviolet (UV)-induced DNA damage is a crucial molecular trigger for sunburn cell formation and skin cancer. Nucleotide excision repair (NER) is the main mechanism in repairing UVB-induced DNA damage to mammalian cells. The purpose of this study was to investigate the functional role of ginsenoside Rb1 in UV-induced DNA damage and apoptosis in HaCaT(More)
Simultaneous relief of the pain from body and brain remains an ongoing challenge. The aim of the present study was to clarify whether plant-derived isoflavone puerarin could ameliorate comorbid depression and pain. We investigated the effects of puerarin on depressive-like behaviors and neuropathic pain in C57BL/6 N mice with spared nerve injury (SNI).(More)
The seed oil of Euphorbia lathyris L. contains a series of macrocyclic diterpenoids known as Euphorbia factors. They are the current industrial source of ingenol mebutate, which is approved for the treatment of actinic keratosis, a precancerous skin condition. Here, we report an alcohol dehydrogenase-mediated cyclization step in the biosynthetic pathway of(More)
OBJECTIVE To evaluate the benefits of conditioned medium of Adipose-derived stem cells (ADSC-CM) on wound healing after fractional carbon dioxide laser resurfacing (FxCR) on human skin. MATERIALS AND METHODS Nineteen subjects were treated with FxCR on the bilateral inner arms. ADSC-CM was applied on FxCR site of one randomly selected arm. Transepidermal(More)
Reactive oxygen species (ROS) are an important factor in the development of skin photodamage after ultraviolet A (UVA) radiation. A flavonoid antioxidant, baicalin, can selectively neutralize super-oxide anion (O(2)(-)) while having no significant effect on (•)OH. Fibroblasts are a key component of skin dermis. In the present study, we investigated the(More)
Vascular endothelial growth factor (VEGF) promotes angiogenesis and plays important roles both in physiological and pathological conditions. VEGF receptors (VEGFRs) are high-affinity receptors for VEGF and are originally considered specific to endothelial cells. We previously reported that VEGFRs were also constitutively expressed in normal human(More)
Mounting evidence indicates that signaling via VEGF receptors (VEGFRs) extends beyond blood vessel formation. Recently, VEGFRs are also found to be constitutively expressed in keratinocytes and epidermal appendages. Here, we show that the expression of VEGFRs (including VEGFR-1, VEGFR-2, and NRP-1) was significantly enhanced by moderate dose of ultraviolet(More)
