In this work, we describe the synthesis, evaluation of some biological properties, such as DNA- and RNA-binding ability and in sero stability, as well as the supramolecular assembly of a novel nucleoamino acid based on
-spinacine. More particularly, a thymine-containing
-spinacine derivative was synthesized in liquid phase by a simple peptide-coupling procedure. Subsequently, nucleic acid and Cu(2+)-binding ability, as well as self-assembly properties of the novel nucleoamino acid, were investigated by spectroscopy (CD and UV) and laser light scattering which furnished interesting information on the assembly of supramolecular networks based on the peptidyl nucleoside analog. Finally, nucleoamino acid enzymatic stability was studied and a half life of about 7 days was found in the presence of fresh human serum.

Docosapentaenoic acid (DPA) is a long-chain n-3 polyunsaturated fatty acid that is intermediary between eicosapentaenoic acid and docosahexaenoic acid in the n-3 synthesis pathway. DPA is part of our ...
The primary purpose of the study is to evaluate the therapeutic efficacy and safety of cholic acid in subjects with identified inborn errors of bile acid synthesis.
OBJECTIVES: I. Determine the effectiveness of oral bile acid therapy with cholic acid, chenodeoxycholic acid, and ursodeoxycholic acid in patients with peroxisomal disorders involving impa...

The purpose of this study is to see if there is a racial and/or gender difference in platelet aggregation.
A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
Tuberculosis resistant to ISONIAZID and RIFAMPIN and at least three of the six main classes of second-line drugs (AMINOGLYCOSIDES; polypeptide agents; FLUOROQUINOLONES; THIOAMIDES; CYCLOSERINE; and PARA-AMINOSALICYLIC ACID) as defined by the CDC.
A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.
An antimetabolite antineoplastic agent with immunosuppressant properties. It interferes with nucleic acid synthesis by inhibiting purine metabolism and is used, usually in combination with other drugs, in the treatment of or in remission maintenance programs for leukemia.
The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
