title: Comparison of fractional picosecond 1064-nm laser and fractional carbon dioxide laser for the treatment of atrophic acne scars: a randomized split-face trial

description: Background: Fractional picosecond laser have been proved to be effective for treatment of atrophic acne scars. However, no studies have compared the efficacy and safety of fractional picosecond 1064-nm laser (FrPico) with fractional carbon dioxide laser (FrCO2), the standard modality for skin resurfacing, in the treatment of atrophic acne scars.Objective: To compare the clinical efficacy and safety of between using FrPico and FrCO2 for the treatment of facial atrophic acne scars. Histological evaluation also elucidated the immediate and long-term skin response after treatments.Methods: Patients (n = 25) with mild to moderate facial atrophic acne scars underwent single session of randomized split-face applying FrPico or FrCO2. Clinical efficacy were assessed by clinical photographs, three-dimensional (3D) photographs and subjective patient satisfaction scores. The clinical safety were recorded in immediate post-treatment pain scores (0-10), levels of burning/stinging sensation (0-10) and adverse event data, recorded at 1-week, 1-month and 3-months follow-up after treatments. Skin biopsies were performed and histological analysis were investigated by two blinded dermatopathologists.Results: Total 25 patients with Fitzpatrick skin types III-V completed the study. For FrPico, physician improvement scores significantly progressed from the 1 to 3-months follow-up in both skin texture and atrophy, with no statistically difference between the FrPico and FrCO2. For 3D photography analysis, significant improvement in scar depression were noted at 1-month and 3-months follow-up for both therapies. But for skin texture, at 3-months follow-up, the statistically improvement was noted only FrPico (P = 0.007). Pain scores and levels of burning/stinging sensation after using FrPico were significant lower than using FrCO2. Post-inflammatory hyperpigmentation (PIH) was not reported in FrPico sides, while there are six patients (24%) experiencing mild PIH on FrCO2 sides at 1 month which faded to trace PIH at 3 months after treatments. Immediate post-FrPico treatment skin biopsied revealed ablation zone at epidermis and upper dermis with zone of collagen fibril disruption extending into the mid to deep dermis. Increased density of collagen and elastic fibers and elastic fiber elongation from both devices at long-term follow-up of both devicesConclusions: FrPico can be used to treat atrophic acne scars as effective as FrCO2 and can maintain the improvement to 3 months after treatment, correlating to evidence of tissue remodeling. None of patients experienced PIH on FrPico sides, so this device may be better option for dark skin types.

title: Essays on corporate governance

description: These essays investigate the role of corporate governance from internationalevidence to firm-level. The first essay provides international corporate governancespillover among country groups, namely G7, BRICS, and PIGS in six dimensions ofcorporate governance of the Worldwide Governance Indicators (WGI) developed bythe World Bank. Empirical evidence shows that there exists corporate governancespillover across these groups. The second essay examines international agency cost instate-owned enterprise (SOE) that determines the effect of ownership structure of SOEon firm performance. Empirically, SOE has positive impact on firm performance,suggesting that SOE firm perform better than non-SOE firm. The third essay exploresthe relationship between corporate governance and stock liquidity in Thailand using atreatment effects. Consistent with prior literature, corporate governance has positiveeffect on stock liquidity and its impact is more pronounced for listed firms with goodcorporate governance. Firms with good corporate governance are viewed to have lowerinformation asymmetry that investors are more confident to trade more stocks, leadingto higher stock liquidity

title: The roles of VIX in international financial markets

description: This dissertation examines the roles of the Chicago Board Options Exchange (CBOE) volatility index (VIX) in international financial markets in three main respects that have not examined in prior literature. The first issue is cross-country spillover from VIX to international equity markets around the globe. This study applies the model that can capture tail codependences between VIX and three market index activities, namely return, volatility and volume during extreme market episodes, namely financial crisis and bubble. This study finds that tail codependences between VIX and market index variables exist and the impact of VIX is asymmetry that is more pronounced when markets are extremely bearish, highly volatile and very low in volume. Based on market development level and geographical location, this study additionally finds that VIX has higher dependence with return in developed and European markets and with volatility in emerging and Latin America markets respectively during extreme market scenarios.The second issue is the dynamic interdependence between implied volatility indices in international countries that employs the CBOE’s model-free methodology to construct their own volatility indices based on their respective underlying main stock market indices and three types of the U.S international portfolio investment, namely net U.S. purchases, U.S. purchases and U.S. sales. This study finds the one-way causal directional relation from fear indices in international countries to the U.S. international portfolio investment. The impact of local fear indices on net U.S. purchases is negative, suggesting that U.S. investors become net sellers during high fear. Based on geographical locations, local fear indices in Europe have the positive effect on U.S. purchases and U.S. sales whereas those in Asia-Pacific are opposite. Due to a “flight-to-quality” phenomenon, U.S. investors move their capitals by purchasing European stocks for safer assets and selling Asia-Pacific stocks for riskier ones. However, because of a greater benefit of international portfolio diversification in Asia-Pacific than in Europe, when investor fear in Asia-Pacific countries is high, U.S. investors sell their stocks fewer than they should do.The third issue is to use implied volatility indices of the CBOE as a new alternative measure of volatility to investigate its relation with trading volume in three financial instruments, namely commodity ETFs, stock indices and stock-ETFs. Consistent with recent literature, the positive relation between volume and implied volatility exists and becomes more pronounced in the higher distributions, demonstrating its asymmetric relation. This study finds that the volume-implied volatility relation displays a non-linear property in many financial assets. This study also suggests three behavioral concepts of availability, extrapolation and conservatism biases to explain this positive relation that cannot be explained by information-based hypotheses.

title: Comparative study of localized intradermal microinjection of tranexamic acid in different doses for treatment of melasma in Thai patients

description: ABSTRACTIntroduction: Nowadays, there are numerous treatment modalities for melasma. However, the results still vary and have not been able to reach satisfactory outcomes. Intradermal microinjection of tranexamic acid (TA) has been reported as an alternative treatment for melasma. Objective: To evaluate the efficacy and safety of tranexamic acid (TA) intradermal microinjection in treatment of melasma, between 50 mg/ml TA versus 4 mg/ml TA in reducing melanin level and modified Malasma Area Severity Index scoring (mMASI score). Method: Thirty four patients with melasma were enrolled a prospective, randomized, triple-blinded, split-faced trial. TA 50 mg/ml was randomly intradermal microinjection to one side of the face and 4 mg/ml TA was injected to the other side every 2 weeks for 12 weeks and follow up 1-month after the last treatment. All patients were instructed to applying the SPF 50 sunscreen to both side of the face in every morning. Clinical images were taken monthly including melanin level and hemoglobin level by using the skin analysis camera (Antera3D®), mMASI score which evaluated by two dermatologists, side effects to assess the clinical response. Patients’ self-assessment score was assessed at 1-month follow up after the complete treatment protocol.Results: Although, the significant decreased in mMASI score and melanin level was observed in both concentrations but the side treated with 50 mg/ml TA could achieve the better result in shorter period comparing to the other side of face which treated with 4 mg/ml TA. Furthermore, in the sided treated with 50 mg/ml, there was 34 % improvement in mMASI score and 13 % improvement in melanin level comparing to 25 % and 5 %, respectively in the side treated with 4 mg/ml. At 1-month follow up, there was significant decrease in mMASI score and melanin level in both sides of the face. No any serious adverse effect was observed. Majority of the patients preferred 50 mg/ml TA intradermal microinjection than 4 mg/ml. 85% of the patients scored as excellent improvement on the side treated with 50 mg/ml comparing to 4 mg/ml which was scored 35% as excellent improvement.Conclusion: Intralesional microinjection of 50 mg/ml TA showed a statistically significant decrease in melasma without any serious side effects. Moreover, 50 mg/ml of TA showed superior to 4 mg/ml in term of improvement in melasma and also can reach the better result in the shorter period of time.  Therefore, 50 mg/ml TA appeared to be a therapeutic option or adjunctive treatment for melasma.Keywords: Melasma, Melasma pathogenesis, Melasma treatment, tranexamic acid     (TA), intradermal microinjection

title: Consumer attitude recovery in social media

description: Failure to obtain consumer attitude recovery, resulting in negative word of mouth spreading over social media, could lead to brand crisis. Prior social network research has focused on antecedents of electronic word of mouth (eWOM) diffusion in social media and their effects, but only limited research has focused on brand crisis response strategy communication in social media considering eWOM diffusion antecedents and consumer characteristics. The current study argued that social influence, which includes information source homophily (i.e., similarity among members) and public opinions (i.e., message consensus) and consumer-brand relationship (CBR), significantly contributed to consumer attitude recovery via crisis response strategy communication effectiveness in online communities. This study explored antecedents that alter the degree of negative effect of negative eWOM and positive effect of crisis response strategy on consumer attitude. Social network theory was employed to explore the role of source homophily and message consensus, while the elaboration likelihood model was applied to explain the role of CBR on consumer attitude recovery after processing online information that included negative eWOM of the brand and brand response strategy. The research employed an experimental design on a well-known restaurant regarding unsatisfactory service recovery and crisis response strategy communication in social media. A total of 424 respondents were randomly assigned to eight scenarios. The study found that high-consensus information from high-homophily source produced a stronger impact than low-consensus information from low-homophily source. Accommodative strategy was prone to be preferable to defensive strategy. Surprisingly, high CBR generally did not buffer the negative effect of negative eWOM, and it likewise did not enhance the positive effect of crisis response strategy for life threathening incident. However, source homophily and message consensus mitigate the negative impact of negative eWOM on high-CBR consumers (compared to low-CBR consumers) while enhancing the positive effect on high-CBR consumers (compared to low-CBR consumers). This study introduced a framework of consumer attitude recovery in social media.

title: Marketing–operations alignment: scale development and validation

description: Despite the growing importance of a strong strategic alignment between different functions of a firm in relation to retaining competitive advantages, there is still no consensus model of marketing-operations alignment within firms. However, marketing-operations alignment is widely considered a key cross-functional alignment for firms, since this alignment affects a wide range of areas in their operations. The purpose of this study is to advance the state of knowledge regarding cross-functional alignment between marketing and operations. The study used configuration theory as the basis for explaining how and why this internal alignment develops within firms. The objectives of the study included establishing a concept of marketing-operations alignment, developing and validating a measure of marketing-operations alignment in manufacturing firms, and testing of the relationship between marketing-operations alignment and key strategic orientations (customer orientation and competitor orientation). Following establishment of a basic theoretical framework, the dimensions of marketing-operations alignment were established by using case interviews with subject matter experts that identified potential dimensions and relationships. This was followed by a Q methodology process to develop consensus on the dimensions. A survey (n = 419) was used to evaluate the reliability and validity of the factor structure of the marketing-operations alignment construct and the -operations alignment construct and the proposed relationships within the framework. The results of the study validated the marketing-operations alignment construct and the instrument developed to measure marketing-operations alignment in firms by using structural equation modeling (SEM).  This instrument and its underlying theory provide tools for evaluating functional alignment within firms.

title: Comparative study of photodynamic therapy with riboflavin-tryptophan gel and 13% 5-aminolevulinic acid in the treatment of mild to moderate acne vulgaris

description: Photodynamic therapy (PDT), a non-invasive procedure, has been used as an effective alternative acne treatment for many years. The ordinary photosensitizing agents are 5-aminolevulinicacid (ALA) and methyl aminolevulinate (MAL). Currently, riboflavin and tryptophan are new natural photosensitizers introduced for the treatment of acne vulgaris.     The objective of this study is that we would like to investigate the efficacy and safety of the photodynamic therapy with riboflavin-tryptophan gel comparing to 13% 5-aminolevulinic acid in the treatment of mild-to moderate facial acne vulgaris. We performed a double-blind, split face study in 37 subjects with mild to moderate acne vulgaris on both side of the face. Half of the face were applied with RT gel, while the other half will be applied with 13% 5-aminolevulinic acid for 30 minutes and then the whole face were irradiated using a blue light-emitting diode for 20 minutes. Four treatment sessions were performed over a 4-week duration, 1-week interval. The lesion counts and acne severity were assessed by a blinded examiner. Propionibacterium acne, sebum secretion, post inflammatory erythema, post inflammatory hyperpigmentation of acne and safety were also evaluated.    From all 35 subjects who had completed the treatment and follow-ups. The results from PDT-RT gel has shown good efficacy non-inferior to 5-aminolevulinic acid for acne treatment. There was significant reduction in acne lesion counts and acne severity grading in PDT-RT gel since the first week after treatment. Besides, significant porphyrin and sebum output reduction were also detected, corresponding with the improved clinical presentation. The side effects were minimal and well-tolerated in all subjects. Moreover, PDT with RT-gel also showed greater improvement in pore size, skin roughness and wrinkle than PDT with ALA when comparing within each group. The volume median decreased from 3.4 to 2.38 (p-value=0.006) in PDT with RT-gel, while decreased from 3.4 to 2.8 (p-value=0.003) in PDT with ALA. In RT-gel, both skin roughness and wrinkle demonstrated statistical significant improvement starting from 2 weeks after treatment.     In conclusions, photodynamic therapy with riboflavin and tryptophan gel can be served as new alternative treatment regimen for acne vulgaris because of good efficacy, safety and well-tolerability. Besides, PDT with RT gel was effective for facial skin rejuvenation in terms of pore size, skin texture and wrinkle.

title: Effect of calcipotriol NBUVB-induced MMP-9 in human skin in vivo

description: Ultraviolet B (UVB) irradiation plays a key role in skin damage, which induces oxidative and inflammatory damages, ultimately leading to photoaging or photocarcinogenesis. It activates the induction of matrix metalloproteinases (MMPs) and other extracellular matrix degrading enzymes. Gelatinase B (MMP-9) not only acts as a main role to digest type I, III collagen fragments which leads to the sign of photoaging, but it also degrades type IV collagen fibers, primary protein components of basement membrane in skin, leading to photocarcinogenesis.Calcipotriol is a synthetic analog of 1,25-dihydroxyvitamin D3 which has potent cell regulating properties. There were previous reports about in vitro vitamin D-mediated MMP-9 expression in many cells types, including human prostate cancer cells, human uterine fibroid cells, human lung fibroblasts, human nasal polyp-derived fibroblasts and human squamous cell carcinoma cell line.In this study, we used MMP-9 as a key marker, indicating photoaging and photocarcinogenesis, and test whether topical calcipotriol could prevent narrowband UVB-induced MMP-9 in human skin. Seven healthy Thai volunteers were applied calcipotriol ointment for three consecutive days with twenty-four hours apart. Narrowband UVB (NBUVB) irradiation was administered to lower back skin which left side is calcipotriol’s zone and right side is normal skin. At twenty-four hours post radiation, skin was biopsied for RT-PCR. However, only five volunteers’ specimen were completely performed due to some issues in the laboratory procedure.   The results showed that NBUVB irradiation caused increase in the relative MMP-9 mRNA expression but the result cannot conclude as statistically significant. Moreover, calcipotriol pretreatment has a possibility to reduce the relative expression of NBUVB induced MMP-9 mRNA but also not significant.Our pilot study demonstrated for the first time that topical calcipotriol had a potential to provide protective effect against NBUVB-induced MMP-9 mRNA in human skin. However, for limited numbers of subjects, the results cannot reach statistical significant. Further studies are suggested to confirm and expand these findings.

title: Efficacy and safety of MAS062D moisturizer lotion versus hydrophilic cream in improving the skin moisturization and skin barrier function and in xerosis in the elderly : A split site, double-blinded, Randomized, controlled trial

description: Xerosis is very common problem in elderly characterized by erythema, dry scaling or fissuring and either the presence or absence of pruritus which could be treated by moisturizer with anti-inflammatory ingredients without steroid to help moisturize and calm skin from inflammation. The aims of this study were to evaluate the efficacy and safety of MAS062D moisturizer lotion versus hydrophilic cream in improving the skin hydration and skin barrier function in the treatment of xerosis in the elderly. A split site, double-blinded, randomized, controlled trial was conducted in patients with mild to moderate xerosis. The patients applied MAS062D and hydrophilic cream on the assigned shins twice daily for 28days. The evaluations on each consecutive following up days (day 0, 14 and 28) were performed using clinical assessment, photography, measuring skin hydration by corneometer, transepidermal water loss (TEWL) by Tewameter and biometric assessment. Twenty four patients were included into the study of which 87.5% were female with mean age of 58.04 years and mean xerosis severity scale (XSS) of 4.83. MAI treated side have got the same statistically significant improvement in clinical assessment by XSS with the values of hydrophilic treated side presented at 4.83 ± 0.7, 3.33 ± 0.82 and 1.83 ± 0.82 on baseline, day 14 and 28 respectively. On the following up day 14 and 28, it indicated the statistically significant decrease in TEWL values measured by tewameter of the MAI treated side (5.4 ± 3.18g/m2h) (4.83 ± 1.84 g/m2h)  compared to the hydrophilic cream treated side (8.63 ± 3.92g/m2h) (8.54 ± 4.53 g/m2h) (p
