XYLARIC ACID, D-ARABINARIC ACID (D-LYXARIC ACID), L-ARABINARIC ACID (L-LYXARIC ACID), AND RIBARIC ACID-1,4-LACTONE; SYNTHESIS AND ISOLATION - SYNTHESIS OF POLYHYDROXYPOLYAMIDES THEREFROM
<p>This dissertation describes the nitric acid oxidation of the pentoses D-xylose, L-arabinose, D-arabinose, and D-ribose to produce xylaric acid, L-arabinaric acid (L-lyxaric acid), D-arabinaric acid (D-lyxaric acid), and ribaric acid, respectively, or salts therefrom. Isolation of the aldaric …

Mannaric Acid and Mannaric Acid Polyamides: Synthesis and Characterization
… respectively. Historically, D-mannaric acid has been prepared by the nitric acid oxidation of D-mannose. The first published report comes from Haworth et al. in 1944 with D-mannaric acid isolated as crystalline D-mannaro-1,4:6,3-dilactone. Nitric acid has been employed for the conversion …

Amino acid transporters & amino acid metabolism in Trypanosoma brucei brucei
… the entry of drugs into the cell. Some amino acid transporters fulfil the criteria needed for successful exploitation of nutrient transport systems for drug delivery. The Trypanosoma brucei genomic database was screened to identify the full gene repertoire of amino acid transporters. From …

Nucleic acid biosensors
… volume element, as well as sophisticated nucleic acid sensors. A flow cell based microsphere platform (electronic tongue), and a novel hydrogel platform based on shape recognition elements (MUFFINS), have been combined with nucleic acid sensors (ssDNA and aptamers) and fluorescence microscopy to …

The crystal structures of sodium bicarbonate, propionic acid and valeric acid
Although Zachariasen was able to determine the gross structure of sodium bicarbonate, his assumptions preclude any conclusions to be drawn concerning the nature of the carbonate group itself. It is therefore the purpose of this paper to reinvestigate the sodium bicarbonate structure employing …

Neuroprotective Functions of Docosahexaenoic Acid and Epidermal Fatty Acid Binding Protein
… Using NGFDPC12 cells we show that palmitic acid (PA) induces the expression of stress response genes HIF-1α and BNIP3, increases the accumulation of reactive oxygen species, and decreases cell viability by apoptosis. Inhibition of cathepsins does not rescue neurons from PA-LTx but inhibition …

Utilization of abomasally infused ribonucleic acid and deoxyribonucleic acid in sheep
… was significantly elevated for the nucleic acid infusions over that for the sham. The RNA value, though not different from DNA or the combination, was comparable to that for the soy. Calculated by difference, the absorption values of RNA, DNA, and the combination of RNA and DNA were 97, 77, …

Study of poly (l-lactic acid)/poly (d-lactic acid) stereocomplex as nucleating agent for poly (l- lactic acid) crystallization
Poly (lactic acid) (PLA) is a biodegradable polymer with good renewability and processability. However, it has some drawbacks. The Poly (lactic acid) (PLA) stereocomplex formed via the interaction between optical isomers Poly (L-lactic acid) (PLLA) and Poly (D-lactic acid) (PDLA), provides …

The role of dietary arachidonic acid and docosahexaenoic acid in preventing the phenotype observed with highly unsaturated fatty acid deficiency
… physiological roles of highly unsaturated fatty acids (HUFA), mainly arachidonic acid (AA, 20:4ω6) and docosahexaenoic acid (DHA, 22:6ω3), are not completely understood. In order to study specific functions for AA and DHA, a delta-6 desaturase knockout (D6D-/-) mouse was created. D6D is a key …

Ursolic acid and oleanolic acid as novel therapeutic agents in breast cancer
… The effects of non-toxic triterpenes, oleanolic acid and ursolic acid and the role of autophagy and apoptosis as mechanisms to overcome drug resistance in breast cancer were studied in vitro in MCF-7 breast cancer cells and MCF10A breast cells. In this study the first aim was to establish the …

Tetracycline-7-boronic acid
The objective of this study is the preparation of a tetracycline-boron-10 derivative which is stable under biological conditions. The boron-10 should then provide a concentration of material capable of accepting thermal neutrons, thus producing localized high-energy alpha radiation. The fact that …
