Abstract:

New metal complex derivatives of tppz containing cationic "diquat" sites have been synthesized and characterized. Their interaction with DNA has also been explored .. Water-soluble organic cationic derivatives of the dppz ligand with a variety of functional groups and number of aromatic rings in the phenazine region have also been synthesised and characterized. These systems were synthesized with the aim of modulating the energy of the internal charge transfer excited state of the parent cation. The interactions of the new organic diquaterary salts of dppz with ON A have been studied. Metal co

Abstract:

Depression is one of the most commonly seen psychiatric diseases in the population in recent years. Treatment of depression is mainly carried out by psychiatric drugs. In the past few years, agomelatine which is released to the market with a trade name, Valdoxane, has been thought to have far less side effects due to its non-addictive nature, not having trouble when the drug is quitted, and also due to its property of binding only to the specific receptor that the drug interacts with. The action mechanism of agomelatine on the membrane structure has not been clarified yet, for instance, no stu

Abstract:

Morphogens are secreted signalling molecules that are expressed in restricted groups of cells within the developing tissue. From there, they are secreted and travel throughout the target field and form concentration gradients. These concentration profiles endow receiving cells with positional information. A number of experiments in Drosophila demonstrated that the morphogen Decapentaplegic (Dpp) forms activity gradients by inducing the expression of several target genes above distinct concentration thresholds at different distances from the source. This way, Dpp contributes to developmental fa

Diabetic nephropathy is the most common cause of end stage kidney disease in the world. Newer diabetic medications have arrived over the last few years. However there is lack of experimental and clinical evidence in favour of better outcomes.

O presente estudo teve como objetivo determinar a capacidade antioxidante, antimicrobiana e anti-hemolítica do gengibre (Zingiber officinale) utilizando diferentes solventes extratores. Para tal, rasuras secas de gengibre foram trituradas e usadas na proporção 1:50 (p/v) nas quatro diferentes extrações: água, etanol (70%), acetona/ácido acético (70%/2%) ou acetona (70%). Após centrifugação, o extrato foi utilizado pra determinar o conteúdo de compostos fenólicos por Folin-Ciocalteau e ação sobre os radicais ABTS+. e DPPH.. Foi selecionado o melhor solvente extrator pelas propriedades antioxida

Abstract:

Interactions of progesterone with zwitterionic dipalmitoyl phosphotidylcholine (DPPC) multilamellar liposomes (MLVs) were investigated as a function of temperature and progesterone concentration by using three non-invasive techniques of Fourier transform infrared (FTIR) spectroscopy, turbidity at 440 nm and differential scanning calorimetry (DSC). The results show that 1mol% of progesterone does not induce a significant change in the shape of thermotropic profile of DPPC. However as progesterone concentration increases, the main transition temperature decreases and phase transition curve broad

Abstract:

博士<br>國立中央大學<br>化學工程與材料工程研究所<br>97<br>The family of prolyl dipeptidases has attracted extensive investigation in recent years because of their unique ability to cleave the peptide bond after a penultimate proline residue. It includes dipeptidyl peptidase IV (DPP-IV, EC 3.4.14.5), FAP (fibroblast activation protein), DPP2 (E.C. 3.4.14.2), DPP8 and DPP9. DPP-IV is the most extensively studied, and the functions for other members are not known so far. DPP9 and DPP8 are highly homologous proteases with 58% sequence identity at the amino acid level. Both the structure and function of these two pro

Both DPP4 inhibitors and GLP-1 analogue have been approved as antihyperglycemic agents in the treatment of diabetes. In addition to the insulinotropic effect, GLP-1 signaling was discovered for the improvement of cardiovascular disease. We examined whether genetic mutation of DPP4 influence cardiac response in both animal model experiments and cell studies. Adult Fischer 344 (wild type)

Abstract:

Prion diseases are fatal neurodegenerative disorders of humans and animals. The prion hypothesis states that PrPSc, a misfolded conformational isoform of the cellular prion protein (PrPC), is the sole component of the infectious particle. Many open questions exist in prion biology including the cellular role of PrPC, the potential involvement of auxiliary factors in prion replication, and the mechanism of PrPSc-induced toxicity in prion disease. The identification of novel prion-like proteins and authentic in vivo prion protein-interacting proteins would certainly assist the process of demysti

碩士<br>國立成功大學<br>化學工程研究所<br>85<br>The hysteresis behavior of air/protein solution interface with or without DPPC monolayer is studied. The air/protein solution interface shows reproducible hysteresis behavior, which implies that both γ-globulin and lysozyme molecules have good respreading ability, and also indicates the characteristics of the slow desorption and fast readsorption behavior of proteins. As tile DPPC monolayer is spread on the air/protein solution interface, the surface pressure jumps immediately and slowly decreases to reach an equilibrium value. The typical collapse behavior

For DPPC/cholesterol mixed system at the air/water interface, the measurements of surface pressure-area per molecule (P-A) isotherms and relaxation curves were carried out. In the thermodynamic analysis of the mixed monolayers, the areas of monolayers exhibited negative deviations from the ideal values at all compositions for lower surface pressures. However, at higher surface pressures, distinctively positive deviations

DPPC and PA are the main compositions of human pulmonary surfactants that contribute to the surface tension-lowering ability of pulmonary surfactants. Previous studies indicated that DPPC alone cannot substitute natural pulmonary surfactant to restore the normal function of a lung because the DPPC monolayer is unstable over its dynamic compression–expansion cycle. A LB film balance system was utilized to monitor the dynamic surface pressure-area iso

The lipid rafts contain 3 to 5-fold the amount of cholesterol found in the surrounding bilayer. Like cholesterol in mammalian cell membrane, ergosterol is important to the raft in the yeast cell membrane. To gain a better understanding of the effect of sterols on biological membrane properties requires investigations of the phase behavior. We study the physical properties of model membranes for binary mixture
