چکیده
The research about molecular weight and functional group analysis of low liquid cyclic natural rubber has been done. aim this is to achievement the quality rubber. This made in several steps such as preparation sample rubber, process degradation characterization LCNR by using FTIR, GPC viscosity test. Degradation done with help phenylhydrazine reagent oxygen gas atmosphere a flow rate 2 LMin-1 for 24 hours. Molecular had result Mw 60,556, Mn 6,661, PDI 11,08613. intrinsic can be used relating it Mark Houwink – Sakurada (MHS) equation get 63.533 weight. C-H stretching bending region are two most difficult regions interpret infrared spectra. ranges between 3300 2750 cm-1 region, more practical regions. frequency which bonds obstructed largely determined type hybridization attributed bond. stronger vibrational force constant, higher vibration frequency.

Low Molecular Weight Heparin Overdose: A 10 Year Case Series
Background: Low molecular weight heparin (LMWH) is used for the treatment and prevention of coagulative disorders. Few patients receiving therapeutic doses of LMWH develop major hemorrhage. Currently there are few reports in the literature on acute overdose on adults. In this study, clinical profile, treatment and outcome of 21 patients who acutely overdosed enoxaparin are described. Method...

I.F. Uchegbu et al. (eds.), Fundamentals of Pharmaceutical Nanoscience, DOI 10.1007/978-1-4614-9164-4_2, © Springer Science+Business Media New York 2013 Abstract Low molecular weight amphiphile micelles are formed from the selfassembly of comparatively hydrophilic amphiphiles (molecular weight <1,500 Da). These structures may be spherical or present as nanofi bres in the case of peptide amphiph...
متن کاملIn vitro biocompatibility of low and medium molecular weight chitosan–coated Fe3O4 nanoparticles
Objective(S): The chitosan - Fe3O4 core - shell nanoparticles were synthesized. The nanoparticles should be coated properly in the shape of core-shell, so that they remain hidden from the body's immune system after coating. Effects of different molecular weight in coating were investigated. Methods: Nanoparticles coated with low and ...
متن کاملPreparation, properties and preclinical pharmacokinetics of low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle
Low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle (LMWH-ISL-SLN) was developed for injective application. The morphological observation, particle diameter and zeta potential of LMWH-ISL-SLN were characterized using transmission electron microscopy (TEM) and a Malvern Zetasizer. Its entrapment efficiency (EE) and drug loading (DL) were determined by ultracen...
