A Review of Melasma , Part 2 : Therapy

Melasma is a common, acquired, and progressive form of hyperpigmentation that occurs most often on the faces of healthy adult women. It also presents in men and in other sunexposed areas, however. The true pathogenesis of melasma remains unknown, although persistent exposure to sunlight is among the most important factors when associated with hormonal changes and a genetic predisposition. Melasma may be triggered by multiple stimuli sufficient to cause functional changes in specifically predisposed melanocytes. Noninvasive subsidiary methods may render clinical examination more objective and accurate, aiming at better diagnosis, prognosis, and therapeutic control. Treatment consists of hypopigmenting agents, chemical peels, microdermabrasion, lasers, and intense pulsed light. A regimen of daily broad-spectrum sun protection is essential to control the progression of melasma and improve treatment. The aim of the treatment is not to cure melasma, but to control it. Several treatments are available, including hypopigmenting agents, chemical peels, microdermabrasion, lasers, and intense pulsed light.
OF NUTRITION FASTING AND HEALTH Is There A Relationship b etween t he Components Of Metabolic Syndrome a nd Depression ?

Article type: Research Paper Introduction: Metabolic syndrome is characterized by at least three out of five main criteria, including high waist circumference, hypertension, high level of triglyceride, low level of highdensity lipoprotein, and elevated fasting blood glucose. The International Diabetes Federation has estimated the prevalence of metabolic syndrome at 25% across the world. Metabolic syndrome is more prevalent in the individuals with depression, as well as other psychiatric disorders. However, the current findings in this regard are conflicting. The present study aimed to evaluate the associations between the criteria of metabolic syndrome and depression as the most common psychiatric disorder. Methods: This cross-sectional study was conducted on 130 participants aged 18-65 years. Metabolic syndrome was assessed based on the criteria of the International Diabetes Federation, and depression was evaluated based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Results: After the adjustment of the important confounders (physical activity, calorie intake, history of depression, depression score, menopausal status, body mass index, and dietary patterns), the waist circumference was observed to be significantly higher in the patients with depression compared to the other subjects. Conclusion: According to the results, visceral obesity may lead to depression and vice versa. Therefore, it is recommended that further investigation be conducted in this regard in order to confirm this association.

S ELF-POWERED CONFORMABLE DEFORMATION SENSOR EXPLOITING THE COLLECTIVE PIEZOELECTRIC EFFECT OF SELF-ORGANIZED G A N NANOWIRES

We present a novel integration-driven approach to the design of multi-scale multiphysics sensors and systems. We implement this method to model, design, fabricate and characterize a thin, conformable low-cost impact detection sensor based on assemblies of piezoelectric GaN nanowires. When suitably assembled, the latter demonstrate a macroscale additivity of their nanoscale intrinsic properties, which enables to appeal to classical fabrication techniques and exploitable electronic readouts at the system level. We also exploit multi-level simulations to provide useful insights of adapted application-driven integration solutions for these new forms of sensors. We demonstrate the potential of such application-targeted, fully-integrated and modular systems to accommodate to the stringent requirements of structural health monitoring (SHM).
Epitaxial Growth of AlGaN/GaN Heterostructure by Plasma-Assisted Molecular Beam Epitaxy for High Electron Mobility Transistor Applications

AlGaN/GaN heterostructure for the high electron mobility transistor applications were grown by plasma-assisted molecular beam epitaxy (PA-MBE) on the sapphire substrates. The effects of AlN buffer growth parameters on the defect structure on GaN film were first investigated. For GaN film grown on lower-temperature buffer, the density of screw threading dislocation (TD) was increased while the density of edge TD was decreased. The rough AlN surface helped to bend the growth direction of edge TDs and then reduced the dislocation density through recombination and annihilation processes. However, the screw TD was increased on the rough AlN buffer because this surface provided many nucleation centers for screw dislocation. Further examinations revealed that the edge TD was also closely related to the AlN buffer thickness which corresponding to the stress in GaN film. Total TD density could be minimized by optimizing the AlN buffer growth temperature and thickness. GaN buffer grown at Ga-lean condition was found useful to reduce the edge TD density in the GaN film significantly. The Ga-lean buffer, with inclined trench walls on its surface, provides an effectively way to bend the propagation direction and promotes the interaction of edge TDs in the GaN film. As a result, the edge TD density was reduced by approximately two orders of magnitude to 2x10 8 cm -2 . The rough surface of Ga-lean buffer was recovered using migration enhanced epitaxy (MEE), a process of alternating deposition cycle of Ga atoms and N2 radicals, during the PA-MBE growth. By growing the Ga-lean GaN buffer on a iv smooth AlN buffer (achieved by high temperature), both the edge and screw TDs in the GaN film could be effectively reduced. Finally, the roles played by different types of TDs on the electrical properties of AlGaN/GaN heterostructure were studied. From the Hall measurement, the electron mobility in two-dimensional electron gas channel was mainly controlled by the edge TDs. The edge TD acted as Coulomb scattering centers inside the channel and reduced the carrier mobility and increased its resistance. On the other hand, from the Schottky barrier diode characterization, the screw TDs which acted at the current leakage path and was more deleterious to the gate reverse-bias leakage current of the AlGaN/GaN structure. As a result, the output current density and operating frequency of the HEMT devices were decreased by the edge TDs while the device breakdown voltage was degraded by the screw TDs. Therefore, for high performance HEMT device fabrication, both screw and edge TD densities in the AlGaN/GaN material have to be minimized.
Clinical observation on the effect of minimally invasive flapless technique and implant prognosis in oral implants

Objective: To explore the clinical effect of minimally invasive flapless technique and implant prognosis in oral implants. Methods: A total of 88 patients with oral implants placed from February 2016 to December 2017 in Dezhou People’s Hospital were selected. The patients were randomly divided into two groups. The control group used conventional dental implant techniques, and the observation group used minimally invasive flapless technique. The intraoperative conditions and curative effect of the two groups were compared, including the satisfaction of patients, the success rate, the periodontal pocket depth, and dental plaque, as well as levels of inflammatory cytokines interleukin-1 (IL-1), c-reactive protein (CRP), and urinary deoxypyridinoline (UDPd). Results: The operating time, postoperative swelling time, postoperative antibiotic use time and postoperative hormone use time in the observation group were significantly shorter than those in the control group (all P<0.05). Postoperative visual analogue scale score in the observation group was significantly lower than that in the control group (P<0.05). The scores of chewing function, language function, retention function and aesthetic function of the observation group were significantly higher than those of the control group (all P<0.05). The success rate of both groups was 100% after surgery, without significant difference (P>0.05). The periodontal pocket depth and dental plaque index of the observation group were significantly lower than those of the control group (both P<0.05). There was no difference in CRP, IL-1 and UDPd levels between the two groups before and one week after the surgery (all P>0.05). After one month, the above indicators in the observation group were significantly lower than those in the control group, with significant differences (all P<0.05). Conclusion: The use of minimally invasive flapless technique in oral implants has good clinical therapeutic effect, can significantly shorten the operating time, reduce the pain degree of the patients, and reduce the chance of infection, providing a new treatment direction for clinical treatment.
GREEN ’ S FUNCTION FOR AN ELASTIC LAYER LOADED HARMONICALLY ON ITS SURFACE About the authors

The Green’s function in surface displacement plays an important role in soil structure interaction. In evaluating the Green’s function, several difficulties occur because it is formulated in the infinite integral form. This paper outlines a method of analyzing the steady-state dynamic response of an elastic layer subjected to general point load excitation. It is assumed that the load is applied at the surface. The application Hankel integral transform, to the governing differential equations and boundary conditions yields the response displacements at the surface in integral representation. It will be shown that these semiinfinite integrals can be reduced to the integral with the finite range of integration, which can be efficiently taken numerically. The numerical results are presented, which show the efficiency of the developed procedure.

P o S ( I S C C 2 0 1 5 ) 0 5 5 Temporal Data Visualization Technology Based on C #

The development of computer technology brings the type and function expansion of system software and application software in recent years. Visual data shows that the real-time requirement of software has improved continuously. However, the increase of network bandwidth still can’t satisfy modern software development. Since spacecraft vacuum thermal test and control platform demands a fast real-time reaction on collection points collect temperature, current and voltage data. Data security requires the consistency visual data between the client and server. The slow reading speed of visual data may lead a misjudgement on the evaluation of the thermostat operator on environmental conditions in the vacuum vessel. This situation may bring disastrous consequences. This article proposes a compression algorithm which can solve the problem of a large amount; in addition, we design the information visualization technology of Fisheye Lines. This technology displays holistic view of large data sets in quickly way, it is also easy to see the details.
How Does International Migration A¤ect the Health of Elderly Parents Left Behind? Evidence from Mexico

This paper considers whether the health of elderly parents is adversely a¤ected by the international migration of their adult children. Estimation of a causal e¤ect is complicated by the fact that there may be unobserved factors inuencing both parental health and child migration. I address this endogeneity problem by using an empirical strategy with individual parent xed e¤ects thus purging the estimates of biases due to time-invariant selection factors. For robustness, I also o¤er an additional identi cation strategy based on instrumental variables methods, where the instruments used in the analysis are characteristics of the children of elderly parents. Overall, evidence from both identi cation strategies suggests that having a child migrate to the U.S. raises the probability that the elderly parent in Mexico will be in poor health. Speci c health outcomes providing support for this conclusion include poor self-rated health status, obesity, and feelings of loneliness and depression.

What Australian Consumers like about Fruit Juice : Results from a Hedonic Analysis

Fruit juice is a heterogenous product. Firms in the Australian fruit juice industry compete primarily through the development of new products, and not through price. Consumers are given a choice of different fruit blends, sizes and concentrations. The development of products with a wide range of characteristics has occurred because manufacturers and retailers evidently believe that consumers place a value on these characteristics. The primary aim of the paper is to investigate the part played by the quality attributes of fruit juice in influencing fruit juice consumption. The focus of the study is on the overall market valuation of the various fruit juice characteristics, and is not particularly concerned with consumers’ valuation via their preferences nor producers’ factor costs. Data collected from a major South-East Queensland supermarket is employed to try to infer the value consumers place on these attributes. The methodology followed is based upon Lancaster’s (1991) attributes model. Two models are proposed in this paper: a linear and polynomial model. According to the results, consumers pay a premium for nutrition, convenience and information. Models such as these are important adjuncts for marketers of fruit juice, as the estimation of implicit prices are potentially useful tools in strategic marketing.
Learning Analytics: Principles and Constraints

: Within the evolution of technology in education, Learning Analytics has reserved its position as a robust technological field that promises to empower instructors and learners in different educational fields. The 2014 horizon report (Johnson et al., 2014), expects it to be adopted by educational institutions in the near future. However, the processes and phases as well as constraints are still not deeply debated. In this research study, the authors talk about the essence, objectives and methodologies of Learning Analytics and propose a first prototype life cycle that describes its entire process. Furthermore, the authors raise substantial questions related to challenges such as security, policy and ethics issues that limit the beneficial appliances of Learning Analytics processes.
Banks' Holdings of Risky Sovereign Bonds in the Absence of the Nexus: Yield Seeking with Central Bank Funding or De-Risking?

For the largest 55 German banks, we detect the presence of countercyclical yield seeking in the form of acquisition of high-yielding periphery bonds in the period from Q1 2008 to Q2 2011. This investment strategy is pursued by banks not subject to a bailout, banks characterised by high capitalisation, banks that rely on short-term wholesale funding, and trading banks. In the subsequent period up to 2014, these banks switched to a procyclical divestment strategy resulting in the sale of risky assets. Following the launch of the public sector purchase programme (PSPP) in 2015, a clear investment pattern can no longer be identified. Unlike existing evidence for banks domiciled in vulnerable countries, we find that the recourse to central bank finance is rather limited and does not affect the risk-taking behaviour of banks in the non-stressed country Germany. Yield-seeking strategies were predominantly pursued by healthy banks in Germany. This contrasts with the increases in domestic sovereign holdings in vulnerable countries which can be primarily regarded as the result of moral suasion or, for weakly capitalised banks, a kind of "indirect" moral suasion or "home-biased" gambling for resurrection.
Diabetic nephropathy : Pathogenesis and therapeutic management

Nephropathy is considered a foremost cause of morbidity and mortality in patients with type 1 or type 2 diabetes mellitus. Hyperglycemia causes renal injury directly or via hemodynamic alterations. These alterations induce glomerular hyperfiltration, microalbuminuria, mesangial expansion, and GBM thickening and arteriolar hyalinosis. Risk determination has potential importance in the management of Diabetic Neuropathy advancement. In addition to the traditional approaches through albuminuria and glomerular filtration rate for the prediction and monitoring of the rate of damage among diabetic patients, various studies are enduring to identify biomarkers. Recent approaches to treat this disorder emphasize on increased control of glycemia and blood pressure using therapies based on renin-angiotensinaldosterone system blockade. Renal and pancreatic transplantation is considered the best modality. This review of literature focuses on pathogenic factors, risk factors, diagnosis and treatment of diabetic nephropathy.
Preparation and characterization of electrospun composite nanofibers from poly(vinyl alcohol) /lignocellulose nanofibrils with different chemical compositions

Lignocellulose nanofibrils (LCNFs) were prepared using Liriodendron tulipifera L. wood flour. Electrospun nanofibers were fabricated by mixing the LCNFs with poly(vinyl alcohol) (PVOH). The lignin and hemicellulose contents of the wood flour were controlled with an alkaline-peroxide treatment at a pH of 11.5 using various hydrogen peroxide concentrations. The morphological characteristics, mean diameter, and filtration time of the LCNFs subjected to wet disk milling (WDM) and high-pressure homogenization were determined. Furthermore, the spinning suspension viscosity was measured with various LCNF concentrations and PVOH/LCNF addition ratios. After the alkaline-peroxide treatment, the lignin and hemicellulose contents decreased with an increasing hydrogen peroxide concentration and reaction time. As the lignin content decreased, the nanofibril diameter decreased and the filtration time increased. The diameter decreased further after the homogenization treatment following WDM. The viscosity of the mixed solution increased with an increasing PVOH and LCNF mixed solution concentration and LCNF addition ratio, and decreasing lignin content. Scanning electron micrographs revealed that the diameter of the electrospun nanofibers increased as the mixed solution concentration and LCNFs addition increased, the lignin content decreased, and with the homogenization treatment.
A new algorithm on the automatic TFT‐LCD mura defects inspection based on an effective background reconstruction

In this study, an automatic detection method for mura defects is developed based on an accurate reconstruction of the background and precise evaluation of the mura index level. To achieve this, an effective background reconstruction method is first developed to represent the brightness intensity of the display panel. As a result, any nonuniform brightness of the background can be removed effectively. Furthermore, the associated mura level is quantified based on the sensitivity of the human eye in order to alternatively grade the liquid‐crystal display panels. The main focus of this study is on the reconstruction of the background from the display under test image. The proposed method takes full advantage of the following three existing methods: low‐pass filtering, discrete cosine transform, and polynomial surface fitting. By applying the method to several case studies, we have shown that it is more effective compared with other existing methods in detecting various types of mura defects.
