Resistant starch type 3 (RS-3) holds great potential as a prebiotic by supporting gut microbiota following intestinal digestion. However the factors influencing digestibility of RS-3 are largely unknown. This research aims to reveal how crystal and molecular weight (distribution) influence its resistance. Narrow polydisperse ?-glucans degree polymerization (DP) 14–76, either obtained enzymatic ...

This Application Note shows the determination of protein molecular weight and size, together with linear quantifi cation using the Agilent 1260 Infi nity Multi-Detector Bio-SEC Solution. The molecular weights and sizes of proteins, ranging from cytochrome C (11 kDa) to thyroglobulin (670 kDa) were correctly determined, independent of sample loading. Using the dual angle light scattering detecto...

The use of low molecular weight heparins (LMWH) in obstetric care has grown considerably since their introduction into clinical practice in the early 1990s. However, because of the physiological changes of pregnancy, the predictable pharmacokinetic profile of LMWH is lost and some uncertainty exists around the optimal dosing regimen for LMWH in obstetric care. Two recent United Kingdom prospect...

The seven reviews and the eleven articles in this special issue provide an updated survey of recent research and developments in the ever-growing field of heparin, along with low molecular weight heparins (LMWHs) and glycosaminoglycans (GAGs).

Background The National Patient Safety Agency issued a rapid response report in July 2010 aimed at reducing treatment dose errors with low molecular weight heparins (LMWHs) (1). This states: “incident reports indicate patients renal function is often not taken into consideration when prescribing treatment doses of LMWHs. Not considering renal function was the leading causes of error resulting i...

DNA size markers (ladder) are essential tools in molecular biology, genetics and biotechnology. In this study, a simple and cost-effective method for laboratory production of DNA ladders is introduced. For this purpose, different sizes of 100 to 2000 bp DNA segments were designed using PCR technique. For producing 14 different gene fragments as DNA molecular weight markers, recombinant plasmid ...

ethylene was homopolymerized over ziegler-natta catalyst and the homopolymerization was modeled using moment equations. mechanism was modeled according to five different reaction centers of catalyst. for each center, there are different reaction rate coefficients; therefore the final product of each center would be expected to be different. modeling results showed good conformity to the experim...
