Garcinia mangostana Linn extract (GME) is a natural product that has received considerable attention in cancer therapy, and has the potential to reduce side effects of chemotherapeutics and improve efficacy. We formulated GME-encapsulated ethyl cellulose (GME-EC) and a polymer blend of ethyl cellulose and methyl cellulose (GME-EC/MC) nanoparticles. We achieved high drug-loading and encapsulatio...

1. Purified ficin was chemically attached to CM-cellulose, and partially purified ATP-creatine phosphotransferase was chemically attached to both CM-cellulose and p-aminobenzylcellulose. 2. The apparent K(m) with respect to ATP and Mg(2+) of ATP-creatine phosphotransferase was observed to increase about tenfold on attachment of the enzyme to CM-cellulose, and to increase by only 23% on its atta...

Xylanase A (Pf Xyn10A), in common with several other Pseudomonas fluorescens subsp. cellulosa polysaccharidases, consists of a Type II cellulose-binding domain (CBD), a catalytic domain (Pf Xyn10A(CD)) and an internal domain that exhibits homology to Type X CBDs. The Type X CBD of Pf Xyn10A, expressed as a discrete entity (CBD(X)) or fused to the catalytic domain (Pf Xyn10A'), bound to amorphou...

Recent developments in cellulose wound dressings targeted to different stages of wound healing have been based on structural and charge modifications that function to modulate events in the complex inflammatory and hemostatic phases of wound healing. Hemostasis and inflammation comprise two overlapping but distinct phases of wound healing wherein different dressing material properties are requi...

Water, one of the most important resources that planet offers us, cannot be used without meeting certain quality parameters which are increasingly difficult to achieve due human activities such as deforestation, improper industrial and agricultural waste management, maritime traffic fuel spillages. Cellulose-based materials or membranes among candidates water treatment processes in actual conte...

The current spraying of agrochemicals is unselective and ineffective, consuming a high amount fungicides, which endangers the environment human health. Cellulose-based nanocarriers (NCs) are promising tool in sustainable agriculture suitable vehicles for stimuli-responsive release to target cellulase-segregating fungi, cause severe plant diseases such as Apple Canker. Herein, cellulose was modi...

Oxygen atoms within fossil wood provide high-resolution records of climate change, particularly for the Quaternary. However, current analysis methods of fossil cellulose do not differentiate between different positions of the oxygen atoms. Here, we propose a refinement to tree-cellulose paleoclimatology modeling, using the cellulose-derived compound phenylglucosazone as the isotopic substrate. ...
