Abstract
Glycation is an ageing reaction of naturally occurring sugars with dermal proteins, with clinical signs appearing in vivo around age 30, and increasing steadily/regularly with age. The suppleness of the dermis is affected by the formation of bridges between proteins and sugars (Maillard's reaction). The accumulation of advanced glycation end products (AGEs) in skin plays a very important role in skin ageing. Therefore, natural compounds or extracts that possess antiglycation activities may have great anti-ageing potential. In the present study, Silybum marianum flower extract (SMFE) was demonstrated to possess antiglycation activity. We found that SMFE inhibits glycation reaction between BSA and glucose. In addition, antiglycation activity of SMFE was confirmed in a human skin explants model. SMFE reduced Nε-(carboxymethyl) lysine (CML) expression, whereas SMFE stimulated fibrillin-1 expression compared to treatment with methyglyoxal. An active ingredient contributing to the observed activities was identified as silibinin. The antiglycation activity of silibinin was dose-dependent. The beneficial effects of silibinin may be applied to prevention or management of AGE-mediated pathologies, targeting in a pleiotropic and complementary way the biochemical and cellular bases of skin aging.

Abstract
OBJECTIVES The study was designed to evaluate the effect of warfarin on perioperative transfusion, bleeding and coagulation status in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). BACKGROUND There were controversy about the effect of warfarin on perioperative transfusion and bleeding. METHODS/MATERIALS Medical records from 107 consecutive patients with atrial fibrillation (AF) on warfarin therapy undergoing cardiac surgery with cardiopulmonary bypass (CPB) from 2008 to 2013 at a single university teaching hospital were retrospectively reviewed to compare the patients on to those not on warfarin therapy in terms of perioperative transfusion requirement, postoperative 24-h bleeding amount, and coagulation status assessment using prothrombin time (PT), international normalised ratio (INR) and rotational thromboelastometry (ROTEM®). RESULTS Although PT/INR was significantly prolonged both before and after surgery in patients on warfarin therapy, ROTEM® data, perioperative transfusion requirement and postoperative 24-h bleeding amount (785 ± 331 vs 676 ± 303 mL, P = 0·089, respectively) were not significantly different between the patients on and those not on warfarin therapy. CONCLUSION In patients on warfarin therapy undergoing cardiac surgery with CPB, warfarin therapy did not significantly increase perioperative transfusion requirement and bleeding.

Abstract
Camellia japonica oil (CJ oil) has been used traditionally in East Asia to nourish and soothe the skin as well as help restore the elasticity of skin. CJ oil has also been used on all types of bleeding instances. However, little is known about its anti-inflammatory effects. Therefore, the anti-inflammatory effects of CJ oil and its mechanisms of action were investigated. CJ oil inhibited LPS-induced production of NO, PGE(2), and TNF-α in RAW264.7 cells. In addition, expression of COX-2 and iNOS genes was reduced. To evaluate the mechanism of the anti-inflammatory activity of CJ oil, LPS-induced activation of AP-1 and NF-κB promoters was found to be significantly reduced by CJ oil. LPS-induced phosphorylation of IκBα, ERK, p38, and JNK was also attenuated. Our results indicate that CJ oil exerts anti-inflammatory effects by downregulating the expression of iNOS and COX-2 genes through inhibition of NF-κB and AP-1 signaling.

Abstract
In the United States, prenatal genetic testing (PGT) for Autism Spectrum Disorders (ASD) is currently available via clinical genetic services. Such testing may inform parents about their unborn child's risk for ASD, prepare parents for the birth of an affected infant, and allow them to arrange for early interventions. Although PGT for autism has potential benefits, the associated ethical, legal, and social implications (ELSI) should be considered. This first qualitative study employed a hypothetical scenario to explore the attitudes toward PGT and termination decisions of 42 parents of children with ASD. Over half of the participants expressed willingness to undergo PGT for autism. Reasons included better preparation for birth, early and better treatment, termination of affected pregnancy, contribution to research, and curiosity. Of the 31 parents who were either willing or unsure about undergoing the PGT, approximately three-fourths would continue their hypothetical affected pregnancies. Explanations included preparation for birth of the child, bonding or acceptance of existing ASD-affected children, apprehensions about test limitations, and religious concerns. Parents who reported they would terminate the affected pregnancy in this hypothetical situation were primarily Asians. This study contributes to the growing understanding of the ELSI aspects of PGT in clinical practice.

Abstract
In Taiwan, autism spectrum disorders (ASDs) are an emerging public health concern. The ongoing scientific progress for understanding the genetic etiology of ASD makes it increasingly important to examine how parents of children with ASD perceive the causes and recurrence risk of having another child with ASD. These perceptions may influence their family planning, attitudes toward genetic services, and willingness to take their children for ASD genetic testing. However, previous studies addressing this issue were conducted primarily in Western countries. As culture might shape an individual's views of genetic/genomic disorders, this first-of-its-kind study examined the perceptions of the genetic etiology for ASD and the recurrence risk among Taiwanese parents of children affected with ASD. In-depth, semi-structured interviews were conducted among 39 parents having at least one child with ASD. Although the majority of participants believed that ASD has a genetic link, less than half perceived genetic factors as the cause of their own child's ASD. Moreover, most participants articulated their recurrence risk incorrectly. Some parents were concerned about their doctors' limited genomic competencies. To provide parents with better education, counseling, and support for making reproductive decisions, ASD-related genomic education among Taiwanese physicians is needed.

Abstract
The phenolic compound phloretin is a prominent member of the chemical class of dihydrochalcones. Phloretin is specifically found in apple and apple juice and known for its biological properties. We were particularly interested in its potential dermo-cosmetic applications. However, practical limitations of phloretin do exist due to its poor water-solubility. Phloretin was sulfonated with sulfuric acid (98%, wt) and mixed with saturated salt water to produce phloretin 3',3-disulfonate in order to increase its water-solubility. Here we reported the photoprotective effect of phloretin 3',3-disulfonate (PS), a new semi-synthetic derivative of phloretin. Results showed that PS attenuated cyclobutane pyrimidine dimer (CPDs) formation, glutathione (GSH) depletion and apoptosis induced by ultraviolet B (UVB). The photoprotective effect of PS is tightly correlated to the enhancement of nucleotide excision repair (NER) gene expression. Furthemore, PS had inhibitory effects on UVB-induced release of the inflammatory mediators, such as IL-6 and prostaglandin-E2. We also confirmed the safety and clinical efficacy of PS on human skin. Overall, the results demonstrated significant benefits of PS on the protection of keratinocytes against UVB-induced injuries and suggested its potential use in skin photoprotection.

Abstract
This study investigated the effect of 7,8-dihydroxyflavone (DHF) on the expression and activity of heme oxygenase-1 (HO-1), an enzyme with potent antioxidant properties, as well as the molecular mechanisms involved. DHF markedly upregulated HO-1 mRNA and protein expression in human keratinocytes (HaCaT cells), resulting in increased HO-1 activity. DHF also increased the protein level of transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2), which regulates HO-1 expression by binding to the antioxidant response element (ARE) within the HO-1 gene promoter, in a time-dependent manner. Moreover, DHF decreased the expression of Kelch-like ECH-associated protein 1, a repressor of Nrf2 activity, and induced the translocation of Nrf2 from the cytosol into the nucleus, thereby allowing its association with the ARE site. DHF activated extracellular-regulated kinase (ERK) and protein kinase B (PKB, Akt) in keratinocytes, while the ERK and Akt inhibitors attenuated DHF-enhanced Nrf2 and HO-1 expression. DHF also protected the keratinocytes against hydrogen peroxide- and ultraviolet B-induced oxidative damage, while HO-1, ERK and Akt inhibitors markedly suppressed DHF-mediated cytoprotection. Taken together, the results suggested that DHF activates ERK- and Akt-Nrf2 signaling cascades in HaCaT cells, leading to the upregulation of HO-1 and cytoprotection against oxidative stress.

Abstract
Madecassoside (MA), a pentacyclic triterpene isolated from Centella asitica (L.), is used as a therapeutic agent in wound healing and also as an anti-inflammatory and anti-aging agent. However, the involvement of MA in skin-pigmentation has not been reported. This study was conducted to investigate the effects of MA on ultraviolet (UV)-induced melanogenesis and mechanisms in a co-culture system of keratinocytes and melanocytes. MA significantly inhibited UVR-induced melanin synthesis and melanosome transfer in the co-culture system. These effects were further demonstrated by the MA-induced inhibition of protease-activated receptor-2 expression and its signaling pathway, cyclooxygenase-2, prostaglandin E2 and prostaglandin F2 alpha in keratinocytes. The clinical efficacy of MA was confirmed on artificially tanned human skin. MA significantly reduced UV-induced melanin index at 8 weeks after topical application. Overall, the study demonstrated significant benefits of MA use in the inhibition of hyperpigmentation caused by UV irradiation.

Abstract
AIMS This paper describes the development and pilot-testing of The Family Health History Training Program for Health Educators (FHHTP). Although in recent years professional organizations have urged the health promotion workforce to adopt genomics-related competencies, training opportunities designed specifically for health educators (HEs) remain scarce. Designed by a team of HEs, the FHHTP aims at preparing HEs in the state of Texas, USA, to use a family health history as a genomic health promotion tool. METHODS In this report, we describe (a) the program's empirical and theoretical grounding, (b) its components, and (c) pilot-testing of the 2 main components (Web-based and workshop trainings). The FHHTP addresses the training needs expressed by HEs and anchors itself in a theoretical model previously tested with 1,607 US-based HEs. The model draws from Social Cognitive Theory, the Theory of Planned Behavior, and Diffusion of Innovations theory. The program comprises 6 elements; the Web-based training and the training workshops are the focus of this paper. RESULTS Pilot data indicate participants' knowledge and intention improved significantly (p < 0.05) at post-test and remained significantly higher at the 3-month follow-up. Attitudes, self-efficacy, behavior, knowledge/awareness, and intention also exhibited improvement in scores over time. CONCLUSION We conclude, therefore, that the FHHTP can contribute significantly to the adoption of genomic competencies by Texas HEs. This report describes how the first-of-its-kind genomics training for HEs in the USA - FHHTP - was developed and pilot-tested with HEs in Texas.
