Résumé :

This thesis describes GARField magnetic resonance profiling experiments which explore skin hydration and the ingress of small molecules into the skin both in vitro and in vivo. Previous magnetic resonance imaging (MRI) studies of human skin have been severely restricted by the spatial resolution achievable on a clinical scanner as well as by the lower limit of accessible spin-spin relaxation times, T2. Our approach to overcome these limitations is to use a permanent MRI magnet, GARField, specially designed to obtain depth profiles of thin planar samples (about 100 - 800 mum thick) with a pixel

Résumé :

This thesis details novel analysis methods that were applied to investigate shale and clay mineral reactivity as they come in contact with water-based drilling fluids. Six commercial additives were tested and their shale stabilizing potential was investigated through the use of two advanced particle analyzers – FBRM M500 and Malvern Mastersizer 3000. The experimental study and subsequent results indicate that these novel tools can indeed be used to analyze shale hydration and dispersion through particle analysis.

Skin substitutes consist of dermal and epidermal components are very beneficial to improve the current strategies of wound healing. However, these substitutes are not yet a routine treatment for burns or non-healing wounds mainly due to the difficulty of timely obtaining autologous skin cells. The aim of this study is to investigate the immunoprotective role of IDO in bilayer skin substitutes made out of non-autologous cells. To address this aim, first we asked the question of whether tryptophan deficient environment caused by IDO expression is safe for the survival of nonimmune cells, mainly

Background: Barrier creams are applied to the surface of the skin to form a barrier that aims to prevent the penetration of irritants and allergens through the skin surface. Several inconsistencies and controversies exist in literature regarding the effect that barrier creams may have on skin barrier function. Various skin surface parameters are used to evaluate the effect that the barrier creams have on skin barrier function. These parameters include transepidermal water loss (TEWL), skin hydration and skin surface pH. Total skin thickness may be assessed as a variable on its own. Differences

Résumé :

碩士<br>國立中興大學<br>動物科學系所<br>104<br>Oil is recognized as an important component in our diet. Oils or fats which contain high levels of unsaturated fatty acids such as chicken fat are more susceptible to oxidation. During storage, the oxidation of fat and oil might result in the losses of nutritional value, changes in color, texture and sensory properties. Synthetic antioxidants could retard the oxidation process; however, there is an increasing trend of replacing these synthetic antioxidants with the natural ones because of consumer’s demand. Ginger (Zingiber officinale, Zingiberaceae) is widely

Résumé :

Over supplementation of inorganic trace minerals is common practice in the poultry industry which often results in poor bioavailability and low body retention. This can lead to more than 90% of the dietary trace minerals being excreted. The trace minerals Cu, Mn and Zn have been shown to contribute to a healthy skin through their roles in the structural proteins of collagen, keratin and elastin. In this study the effects of replacing industry levels of inorganic Cu, Mn and Zn with lower levels of 2-hydroxy- 4-(methylthio) butanoic acid (HMTBA)2metal chelates of Cu, Mn and Zn was investigated o

Résumé :

Extensive research has already been performed on Aloe vera therefore it is important that researchers include other aloe species, such as Aloe marlothii and Aloe ferox, in studies involving aloe plant materials (Loots et al., 2007:6891). The use of natural products has regained popularity and in recent years the demand for alternative medication has risen considerably (Walji & Wiktorowicz, 2013:86). The hydration state of the human skin is fundamental for its normal functioning (Verdier-Sévrain & Bonté, 2007:75), with healthy skin possessing a water content higher than 10% (w/v) (Blank, 1952:4

Résumé :

Orientação : Luís Monteiro Rodrigues<br>O impacto da obesidade na fisiopatologia da pele humana parece relacionar-se com diversas dermatoses, resultado da alteração da sua fisiologia normal, incluindo alterações na função barreira e na função de “envelope”. Contudo, a informação disponível é ainda escassa devido às diversas complexidades do tema. Este estudo pretende contribuir para a definição de uma metodologia de abordagem experimental para estudar, de forma objetiva, as alterações funcionais que caracterizam a pele obesa. O presente estudo, transversal, incluiu 28 voluntárias, do sexo fem

Résumé :

Orientação: Catarina Rosado<br>A pele é o maior órgão e o mais importante do nosso organismo, uma vez que nos protege contra, não só de agressões externas, como também da perda excessiva de água e electrólitos. Esta função de barreira é exercida pela sua camada mais externa, a epiderme, existindo diversos equipamentos de bioengenharia cutânea que permitem a sua medição. A primeira parte deste trabalho baseou-se na tentativa de optimização do protocolo do POST, pela redução do tempo total da experiência através da recolha de um maior número de pontos na fase inicial do estudo.
