Enzymatic hydrolysis of poly(1,4-butylene 2,5-thiophenedicarboxylate) (PBTF) and poly(1,4-butylene 2,5-furandicarboxylate) (PBF) by Humicola insolens (HiC) and Thermobifida cellulosilytica (Cut) cutinases is investigated. For the first time, the different depolymerization mechanisms of PBTF (endo-wise scission) and PBF (exo-wise cleavage) has been unveiled and correlated to the chemical structure of the two polyesters.

Poly(butylene succinate) (PBS) and poly(lactic acid) (PLA) were melt-blended in different proportions and selectively degraded by cutinase and proteinase K, respectively. The selective enzymatic degra...
Biodegradable polyesters are increasingly used to replace conventional, non-degradable polymers in agricultural applications such as plastic film for mulching. For many of these applications, poly(but...
In the present study, Folic Acid (FA) ligand was used to functionalize Temozolomide-loaded Poly (ethylene Glycol)-Poly (Butylene Adipate)-Poly (ethylene Glycol)-coated magnetite nanoparticles (TMZ-SPI...
In this work, rare earth europium was combined with different organic ligands to obtain two kinds of rare earth conversion agents, Eu(DBM)CPC and Eu(TTA)(TPPO). Two kinds of conversion films were succ...
A novel combined pretreatment process of poplar sawdust was established in this study based on the sequential acetic acid and alkali treatment with poly (ethylene glycol) diglycidyl ether (PEGDE). Eff...
The purpose of this study is to evaluate FluMist with and without Ampligen in healthy volunteers.
The purpose of this study is to determine what side effects CP 870,893 may cause when given with an immune stimulant called Oncovir poly IC:LC along with a melanoma vaccine. The CP 870,893...
The purpose of this study is to test an approach of stimulating the body's immune system to attack prostate cancer. This study will test injection of a substance polylysine and carboxymeth...
RATIONALE: Biological therapies such as poly-ICLC use different ways to stimulate the immune system and stop tumor cells from growing. PURPOSE: This phase II trial is studying how poly-IC...
The study was conducted to determine the therapeutic role of flax seed for Poly cystic ovary syndrome. A sample of 100 subjects were collected. The subjects were from various age group ran...
A poly(A) binding protein that is involved in promoting the extension of the poly A tails of MRNA. The protein requires a minimum of ten ADENOSINE nucleotides in order for binding to mRNA. Once bound it works in conjunction with CLEAVAGE AND POLYADENYLATION SPECIFICITY FACTOR to stimulate the rate of poly A synthesis by POLY A POLYMERASE. Once poly-A tails reach around 250 nucleotides in length poly(A) binding protein II no longer stimulates POLYADENYLATION. Mutations within a GCG repeat region in the gene for poly(A) binding protein II have been shown to cause the disease MUSCULAR DYSTROPHY, OCULOPHARYNGEAL.
A poly(ADP-ribose) polymerase that contains two ZINC FINGERS in its N-terminal DNA-binding region. It modifies NUCLEAR PROTEINS involved in chromatin architecture and BASE EXCISION REPAIR with POLY ADENOSINE DIPHOSPHATE RIBOSE.
A poly(A) binding protein that has a variety of functions such as mRNA stabilization and protection of RNA from nuclease activity. Although poly(A) binding protein I is considered a major cytoplasmic RNA-binding protein it is also found in the CELL NUCLEUS and may be involved in transport of mRNP particles.
Post-translational modification of proteins with POLY ADENOSINE DIPHOSPHATE RIBOSE.
Enzymes that transfer the ADP-RIBOSE group of NAD or NADP to proteins or other small molecules. Transfer of ADP-ribose to water (i.e., hydrolysis) is catalyzed by the NADASES. The mono(ADP-ribose)transferases transfer a single ADP-ribose. POLY(ADP-RIBOSE) POLYMERASES transfer multiple units of ADP-ribose to protein targets, building POLY ADENOSINE DIPHOSPHATE RIBOSE in linear or branched chains.
