FIELD OF INVENTION [0002] The present invention relates generally to methods of improving the aesthetic appearance of human skin and/or 10 improving the appearance of aged and/or photodamaged skin by applying compounds to the skin which stimulate the expression of the extracellular matrix protein MAGP-1 and provide benefits to the skin. BACKGROUND OF THE INVENTION 15 [0003] There is an increasing demand in the cosmetics industry to develop products that may be applied topically to the skin that improve the condition and appearance of skin. Consumers are interested in mitigating or delaying the dermatological signs of chronologically- or hormonally- aged skin, as well as skin aging due to the environmental stress, such as fine lines, wrinkles, sagging skin and other conditions due to a progressive loss of cell growth, proliferation and functionality in the epidermal and dermal skin layers. During the aging process, the complexion of the skin, i.e., the color 20 and appearance of the skin, deteriorates slowly from aging and/or exposure to environmental stress, e.g., sunlight. [0004] There remains a general need in the cosmetics industry for products that retard or counter the aging effects on the skin, and more specifically for products that produce such effects without undesirable side effects. In particular, there remains a need for topically applied cosmetic compositions that provide anti-aging and skin texture benefits using natural plant materials as active components. 25 [0005] Active ingredients or components derived or extracted from plants and plant seeds have commonly been employed for a myriad of medicinal, therapeutic and cosmetic purposes. Such actives may be obtained from the entire plant or various parts of a plant, such as seeds, needles, leaves, flowers, roots, bark, cones, stems, rhizomes, callus cells, protoplasts, and meristems. Active ingredients or components are incorporated in compositions in a variety of forms. Such forms include a pure or semi-pure component, a solid or liquid extract or derivative, or a solid natural plant 30 material. Plant material may be incorporated in a variety of subforms such as whole, minced, ground or crushed, or otherwise physically modified for incorporation into a composition. [0006] Examples of skin beautifying products comprising plant extracts are US 2006/134231 A1 (Amorphophallus), JP 2010 090069 A (Ixora chinensis) and WO 2006/068778 A1 (Sapindus rarak and Thumbergia laurifolia). A peptide- based ingredient (KTFK) is disclosed in WO 2007/093839). 35 [0007] MAGP-1 (Microfibril-associated glycoprotein 1) is a small glycine rich acidic protein in extra-cellular matrix (ECM). MAGP-1 is a 30-33 kDa member of the microfibril associated glycoprotein family of proteins. It was found to be a key component of microfibrils and elastic fibers in skin. MAGP-1 forms complexes with other microfibril proteins such as fibrillin. Besides providing structural support for skin elastic fiber formation, MAGP-1 is also essential for vascular integrity, wound healing, and proper body fat deposition, possibly through regulating TGF-beta signaling, based on 40 animal studies. MAGP-1 apparently mediates the release of Notch extracellular domain and also likely binds to type IV collagen and contributes to elastin fiber formation. [0008] The present invention identifies a particular compound to be active at simulating expression of the extracellular matrix protein MAGP-1. This compound is an N-substituted sulfonyloxybenzylamine having the following structure (I): 45 50 [0009] The N-substituted sulfonyloxybenzylamine as disclosed above has not been known previously for topical ap- 55 plication to skin to improve the skin’s aesthetic appearance. [0010] Antidesma bunius is a species of fruit tree in the spurge family. It is native to Southeast Asia, the Philippines, and northern Australia. Its common Philippine name and other names include bignay, bugnay or bignai and currant tree. This is a variable plant which may be short and shrubby or tall and erect, approaching 30 meters in height. It has large 3 EP 2 588 593 B1 oval shaped leathery evergreen up to about 20 centimeters long and seven wide. The leaves are sudorific and employed in treating snakebite, in Asia. (Morton, J. 1987. Bignay. p. 210-212. In: Fruits of warm climates. Julia F. Morton, Miami, FL.) . [0011] Operculina turpethum is a plant in the morning glory family, (syn. Ipomoea turpethum) and is known commonly as turpeth, fue vao, and St. Thomas lidpod. It is one of many plants mentioned in the literature having claims of activity 5 against liver disorders. Vasudesan, N,V., Indian Medicinal Plants, Vol. IV, Orient Longman Ltd, Chennai, 1995, 172. It also has anthelmintic expectorant, antipyretic, anti-inflammatory and purgative properties. Id. [0012] Ixora chinensis is a fairly small, bushy shrub, usually only 5-10ft tall. There are dwarf varieties that are much smaller. Ixora will flower when only a few inches high. It is commonly used a hedge or small garden plant. The plant is mainly grown as ornamental but its flowers are believed to have some medicinal uses including treatment for hypertension 10 and for treating rheumatism, abscesses, bruises and wounds. The plant is native to India and Sri Lanka [0013] Clerodendron lindleyi are shrubs, lianas, and small trees, usually growing to 1-12 m tall, with opposite or whorled leaves. The genus is native to tropical and warm temperate regions of the world, with most of the species occurring in tropical Africa and southern Asia, but with a few in the tropical Americas and northern Australasia, and a few extending north into the temperate zone in eastern Asia.

  • The Framework Species Approach to Forest Restoration: Using Functional Traits As Predictors of Species Performance
    - 1 - The Framework Species Approach to forest restoration: using functional traits as predictors of species performance. Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Hannah Betts July 2013 - 2 - - 3 - Abstract Due to forest degradation and loss, the use of ecological restoration techniques has become of particular interest in recent years. One such method is the Framework Species Approach (FSA), which was developed in Queensland, Australia. The Framework Species Approach involves a single planting (approximately 30 species) of both early and late successional species. Species planted must survive in the harsh conditions of an open site as well as fulfilling the functions of; (a) fast growth of a broad dense canopy to shade out weeds and reduce the chance of forest fire, (b) early production of flowers or fleshy fruits to attract seed dispersers and kick start animal-mediated seed distribution to the degraded site. The Framework Species Approach has recently been used as part of a restoration project in Doi Suthep-Pui National Park in northern Thailand by the Forest Restoration Research Unit (FORRU) of Chiang Mai University. FORRU have undertaken a number of trials on species performance in the nursery and the field to select appropriate species. However, this has been time-consuming and labour- intensive. It has been suggested that the need for such trials may be reduced by the pre-selection of species using their functional traits as predictors of future performance. Here, seed, leaf and wood functional traits were analysed against predictions from ecological models such as the CSR Triangle and the pioneer concept to assess the extent to which such models described the ecological strategies exhibited by woody species in the seasonally-dry tropical forests of northern Thailand.

  • Tiliacora Triandra) Gum on Gelation of Waxy Rice Flour
    Current Applied Science and Technology Vol. 18 No. 1 Jan.-Apr. 2018 Effects of Yanang (Tiliacora triandra) Gum on Gelation of Waxy Rice Flour Wisutthana Samutsri* and Sujittra Thimtuad Department of Food Science and Technology, Faculty of Science and Technology, Phranakhon Rajabhat University, Bangkok, Thailand Received: 12 July 2017, Revised: 20 March 2018, Accepted: 28 March 2018 Abstract Crude hydrocolloid extract has been prepared from the leaves of Yanang (Tiliacora triandra). This research studied effects of Yanang gum on pasting and textureal properties of blending of waxy rice flour. Rapid visco analysis (RVA) results showed that the ratio of Yanang extract to water of 1:3 and 1:4 (w/w) significantly decreased the trough, breakdown, and final viscosities of the waxy rice flour whereas the peak viscosities, peak time, and pasting temperatures of the blends were increased. Textural study revealed that the addition of crude Yanang gum enhanced more hardness and springiness of the blending gels than those of waxy rice flour gel, whereas cohesiveness was less affected. These results would be useful as a guideline for developing frozen starch-based food products containing crude Yanang gum. Keywords: Yanang, hydrocolloid, waxy rice flour, pasting properties, textural properties, RVA 1. Introduction Retrogradation is a term used for changes that occur in gelatinized starch from disordered state to a more ordered crystalline state and the tendency of starch pastes to thicken and to form stiff gels [1]. Among the cereal, rice is one of the most utilized grains in many forms. Rice flour does not have good handing properties, thus the incorporation of curtain additives as hydrocolloids may be an approach to achieve the desirable properties.

  • Fast and Reliable Detection of Toxic Crotalaria Spectabilis Roth. in Thunbergia Laurifolia Lindl
    Singtonat and Osathanunkul BMC Complementary and Alternative Medicine (2015) 15:162 DOI 10.1186/s12906-015-0692-6 RESEARCH ARTICLE Open Access Fast and reliable detection of toxic Crotalaria spectabilis Roth. in Thunbergia laurifolia Lindl. herbal products using DNA barcoding coupled with HRM analysis Sahachat Singtonat and Maslin Osathanunkul* Abstract Background: Nowadays, medicinal plants are used as a popular alternative to synthetic drugs. Many medicinal plant products have now been commercialized throughout various markets. These products are commonly sold in processed or modified forms such as powders, dried material and capsules, making it almost impossible to accurately identify the constituent species. The herbal plant known as ‘Rang Chuet’ in Thai has been widely used as remedies for various ailments. However, two medicinal plants species, Thunbergia laurifolia and Crotalaria spectabilis share this name. Duotothesimilarityinnomenclature, the commercial products labeled as ‘Rang Chuet’ could be any of them. Recently, the evidence of hepatotoxic effects linked to use of C. spectabilis were reported and is now seriously concern. There is a need to find an approach that could help with species identification of these herbal products to ensure the safety and efficacy of the herbal drug. Methods: Here DNA barcoding was used in combination with High Resolution Melting analysis (Bar-HRM) to authenticate T. laurifolia species. Four DNA barcodes including matK, rbcL, rpoC and trnL were selected for use in primers design for HRM analysis to produce standard melting profiles of the selected species. Commercial products labeled as ‘Rang Chuet’ were purchased from Thai markets and authentication by HRM analyses. Results: Melting data from the HRM assay using the designed primers showed that the two ‘Rang Chuet’ species could easily be distinguished from each other.

  • Hypoglycemic Activity of Leaf Extracts from Tiliacora Triandra in Normal and Streptozotocin-Induced Diabetic Rats
    Pharmacogn J. 2017; 9(5): 621-625 A Multifaceted Journal in the field of Natural Products and Pharmacognosy Original Article www.phcogj.com | www.journalonweb.com/pj | www.phcog.net Hypoglycemic Activity of Leaf Extracts from Tiliacora triandra in Normal and Streptozotocin-Induced Diabetic Rats Teeraporn Katisart1*, Surapong Rattana2 ABSTRACT Background: Tiliacora triandra is a common plant found in southeast Asian countries. It is traditionally used as anti-pyrogenic agent. Objective: The present study was aimed to investi- gate the hypoglycemic activities leaf extracts from Tiliacora triandra (TTE) in normal and strep- tozotocin-induced diabetic rats. Methods: TTE was prepared and daily and orally administered at dose of 300 mg/kg b.w. to the rats for 8 weeks. The body weight and blood glucose level were measured weekly. At the end of the experiments, blood samples were collected from cardiac puncture and analyzed for serum insulin levels. The pancreatic tissues were stained by hematoxylin-eosin for histo-pathological investigations. Results: Normal and diabetic rats treated with TTE and glibenclamide tended to have an increased body weight. TTE significantly decreased the blood glucose level by 25.01 ± 19.77% in week 3 in diabetic rats and similar to that of glibenclamide group (27.01 ± 11.89%). However, the extracts slightly decreased the blood glucose level in normal rats by 9.48 ± 2.14% in week 2. TTE significantly increased serum insulin level by 21.63 ± 1.39 IU/mL in diabetic rats compared to the controls (10.63 ± 0.37 IU/mL) but not in normal rats. In additions, TTE activated the regeneration of pancreatic Islets of Langerhans in diabetic rats which in turn stimulated insulin secretion.
