Image processing has been widely applied in various fields. Photoshop image processing software is the best one for the enthusiasts. At present, more and more people are interested in using Photoshop to create some characteristic pictures, while the key and difficulty part of image processing in Photoshop is matting method(create the image area).In order to help the image processing enthusiasts to accomplish in the process of image processing and create a more beautiful image, this paper introduces several commonly used matting methods in Photoshop and discusses in detail the scope of application, the using methods, the advantages and disadvantages of them. © (2014) Trans Tech Publications, Switzerland.

Hydrogen sulfide (H 2S), is a member of the novel family of endogenous gaseous transmitters, termed gasotransmitters exhibiting diverse physiological activities, and is generated in mammalian tissues mainly by cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3MST) in conjunction with cysteine (aspartate) aminotranferase (CAT). The distributions of these enzymes are species-and tissue-specific. The liver, as the main organ that generates H 2S in vivo, functions in biotransformation and metabolism. However, the liver is vulnerable to damage from internal and external factors, including inflammatory mediators, drugs and poisons. The present study evaluated the endogenous CBS-H 2S synthesis regulating lipopolysaccharide (LPS)-induced apoptosis of hepatic cells. The rat hepatic cell line, BRL, was incubated with LPS for various time periods to establish a cell-damage model. Incubation with LPS resulted in a significant increase in CBS expression and H 2S production. It also stimulated apoptosis and decreased the mitochondrial membrane potential. Pretreatment with the CBS inhibitor aminooxyacetic acid (AOAA) or CBS small interfering RNA (siRNA) decreased LPS-enhanced H 2S production. Notably, apoptosis increased for a short period and then decreased gradually, while the mitochondrial membrane potential demonstrated the opposite trend. These results showed that endogenous CBS-H 2S synthesis demonstrated early anti-apoptotic activity and subsequent pro-apoptotic activity in LPS-induced apoptosis. These results suggest a new approach for developing novel drugs for this condition.

Curculiginis Rhizoma (Curculigo orchioides Gaertn.) is a well-known Chinese herbal medicine, as well as an important Rasayana drug in India. Current criteria of quality control on this herb are to quantitatively analyze single compound curculigoside, which fail to comprehensively evaluate quality of this herb. In this paper, a simple and reliable HPLC coupled with diode array detector (DAD) method was developed to evaluate the quality of Curculiginis Rhizoma through establishing chromatographic fingerprint and simultaneously quantitating four phenolic compounds, orcinol glucoside, orcinol, 2,6-dimethoxybenzoic acid and curculigoside. The fingerprint displayed eleven common peaks, and the similarity index of different samples was in a range of 0.890-0.977. Validation of the method was acceptable, with 96.03-102.82% accuracy in recovery test and inter and intra-day precisions were less than 2%. This developed method by having a combination of chromatographic fingerprint and quantitation analysis could be applied to the quality control of Curculiginis Rhizoma. © 2013 The Pharmaceutical Society of Japan.

A modified benzophenone UV-absorber containing reactive group (4-(4,6-dichloro-1,3,5-triazin-2-yloxy)-2-hydroxyphenyl)phenyl)methanone (UV-DTHM) has been prepared in good yield from the nucleophilic substitution reaction of 2,4-dihydroxy benzophenone with 2,4,6-trichlorotriazine, catalyzed by 1.3 equiv. NaOH. The most favorable reaction conditions (the catalyst dosage, the mole ratio of the reactants, and reactive time) were selected. The compound was characterized by IR spectroscopy, 1H NMR, 13C NMR, mass spectrometry, elemental analysis, and single crystal X-ray diffraction. The crystal monoclinic, space group C c with the unit cell parameters a = 3.987(2), b = 30.688(16), c = 12.423(6) Å and α = 90.00, β = 92.117(15), γ = 90.00º, Z = 4, R = 0.0620. wR(F2) = 0.1589. The crystal structure reveals that 2,4,6-trichlorotriazine is boned to 4-seat hydroxyl of 2,4-dihydroxy benzophenone and a intramolecular hydrogen bond is formed with hydrogen of 2-hydroxyl and oxygen of carbonyl group. Moreover, thermogravimetric analysis (TGA) of UV-DTHM was studied, showing two distinct endothermic peaks at temperatures of 281.5 and 358.5 °C. The molar absorption coefficient of UV-DTHM is 1.6 × 104 and 6.3 × 103 at 268 and 330 nm, respectively, and shows excellent ultraviolet absorption property. © 2015 Springer Science+Business Media Dordrecht

Visualization as one of the important tools for understanding complex phenomenon and resolving large-scale data is observed with a significant application value in natural science field. Since the concept of visualization was proposed in 1986, its research progress is constantly promoted. Based on visualization theory at home and abroad, this study discussed over the significance of introducing visualization theory, performed algorithm design and implementation based on the content and target of computer graphics teaching, and gave out problems found in practical process as well as solutions, in order to change the teaching means of teachers and help students to understand computer graphics algorithm using visualization teaching.
