Green Synthesis of Silver Nanoparticles: Effect of Dextran Molecular Weight Used as Stabilizing-Reducing Agent.

Journal of nanoscience and nanotechnology

Carré-Rangel L, Alonso-Nuñez G, Espinoza-Gómez H, Flores-López LZ.
PMID: 26682423
J Nanosci Nanotechnol. 2015 Dec;15(12):9849-55. doi: 10.1166/jnn.2015.10334.

This paper describes an easy green chemistry method for the synthesis of silver nanoparticles (AgNPs). The AgNPs were obtained through the use of an aqueous silver nitrate solution (AgNO3), with dextrans aqueous solutions of different molecular weights acting as...

The Toxicokinetic Profile of Dex40-GTMAC3-a Novel Polysaccharide Candidate for Reversal of Unfractionated Heparin.

Sokolowska E, Kalaska B, Kaminski K, Lewandowska A, Blazejczyk A, Wietrzyk J, Kasacka I, Szczubialka K, Pawlak D, Nowakowska M, Mogielnicki A.
PMID: 27014072
Front Pharmacol. 2016 Mar 17;7:60. doi: 10.3389/fphar.2016.00060. eCollection 2016.

Though protamine sulfate is the only approved antidote of unfractionated heparin (UFH), yet may produce life threatening side effects such as systemic hypotension, catastrophic pulmonary vasoconstriction or allergic reactions. We have described 40 kDa dextrans (Dex40) substituted with glycidyltrimethylammonium...

Comment on "Solid-Liquid Work of Adhesion".

Langmuir : the ACS journal of surfaces and colloids

Extrand CW.
PMID: 28845989
Langmuir. 2017 Sep 12;33(36):9241-9242. doi: 10.1021/acs.langmuir.7b02476. Epub 2017 Aug 28.

In a recent article, Tadmor and co-workers (Tadmor, R., et al. Langmuir 2017, 33, 3594-3600) used a centrifugal adhesion balance (CAB) to detach liquid drops from solid surfaces. By orienting solid surfaces in their CAB such that normal and...

The Use of Fluorescent Tracers to Characterize the Post-Phloem Transport Pathway in Maternal Tissues of Developing Wheat Grains.

Plant physiology

Wang N, Fisher DB.
PMID: 12232057
Plant Physiol. 1994 Jan;104(1):17-27. doi: 10.1104/pp.104.1.17.

Various polar fluorescent tracers were used to characterize the pathways for apoplastic and symplastic transport in the "crease tissues" (i.e. the vascular strand, chalaza, nucellus, and adjacent pericarp) of developing wheat (Triticum aestivum L.) grains. With mostly minor exceptions,...

Detachment factors for enhanced carrier to carrier transfer of CHO cell lines on macroporous microcarriers.


Landauer K, Dürrschmid M, Klug H, Wiederkum S, Blüml G, Doblhoff-Dier O.
PMID: 19003302
Cytotechnology. 2002 May;39(1):37-45. doi: 10.1023/A:1022455525323.

In this publication different detachment factors were tested for enhancing carrier to carrier transfer for scale-up of macroporous microcarrier based bioprocesses. Two Chinese hamster ovary cell lines, CHO-K1 and a genetically engineered CHO-K1 derived cell line (CHO-MPS), producing recombinant...

Chemotaxis of Rhizobium spp. to Plant Root Exudates.

Plant physiology

Currier WW, Strobel GA.
PMID: 16659577
Plant Physiol. 1976 May;57(5):820-3. doi: 10.1104/pp.57.5.820.

Rhizobium spp. show chemotaxis to plant root exudates. Both legumes and non-legume root exudates attract the different rhizobia studied. However, the bacteria show a differential response in that they are attracted to the root exudates of some plants and...

Contact angles and their hysteresis as a measure of liquid-solid adhesion.

Langmuir : the ACS journal of surfaces and colloids

Extrand CW.
PMID: 15969393
Langmuir. 2004 May 11;20(10):4017-21. doi: 10.1021/la0354988.

The wetting behavior of a series of aliphatic polyamides was examined. Polyamides and polyethylene were molded against glass to produce smooth surfaces. After cleaning, chemical composition of the surfaces was verified with X-ray photoelectron spectroscopy. Advancing and receding contact...

Biocompatible polymers for antibody support on gold surfaces.


Masson JF, Battaglia TM, Davidson MJ, Kim YC, Prakash AM, Beaudoin S, Booksh KS.
PMID: 18970259
Talanta. 2005 Oct 31;67(5):918-25. doi: 10.1016/j.talanta.2005.04.023.

The elimination or minimization of non-specific protein adsorption from serum is critical for the use of surface plasmon resonance (SPR) sensors for in vitro and in vivo analysis of complex biological solutions. The ultimate goals in this application are...

Induced phase separation in low-ionic-strength cellulose nanocrystal suspensions containing high-molecular-weight blue dextrans.

Langmuir : the ACS journal of surfaces and colloids

Beck-Candanedo S, Viet D, Gray DG.
PMID: 17014106
Langmuir. 2006 Oct 10;22(21):8690-5. doi: 10.1021/la061310j.

Spontaneous entropic phase separation phenomena occur in a wide range of systems containing highly anisotropic colloidal particles. Among these are aqueous suspensions of negatively charged cellulose I nanocrystals produced by sulfuric acid hydrolysis of native cellulose, which phase separate...

The binding of divalent metal ions to polyelectrolytes in mixed counterion systems. I. The dye spectrophotometric method.

Biophysical chemistry

Kwak JC, Joshi YM.
PMID: 17000159
Biophys Chem. 1981 Feb;13(1):55-64. doi: 10.1016/0301-4622(81)80025-7.

The dye spectrophotometric method for the measurement of the activity of divalent metal ions in polyelectrolyte solutions containing added electrolytes is discussed. The method is applied to mixtures containing the dextransulfate polyanion, NaCl, and MgCl2 or Ca2. A two...

Insoluble Glucan Formation by Leuconostoc mesenteroides B-1355.

Applied and environmental microbiology

Zahnley JC, Smith MR.
PMID: 16534961
Appl Environ Microbiol. 1995 Mar;61(3):1120-3. doi: 10.1128/aem.61.3.1120-1123.1995.

Leuconostoc mesenteroides B-1355 produced at least three glucosyltransferases (GTFs). We previously identified GTF-2 as alternansucrase and GTF-3 as fraction L dextransucrase. We here show that GTF-1 is a previously unreported sucrase that synthesized water-insoluble dextran. Our evidence consisted of...
