OBJECTIVE Delivery of chitosan to subchondral bone is a novel approach for augmented marrow stimulation. We evaluated the effect of 3 presolidified chitosan-blood implant formulations on osteochondral repair progression compared with untreated defects. DESIGN In N = 5 adult sheep, six 2-mm diameter Jamshidi biopsy holes were created bilaterally in the medial femoral condyle and treated with p...

Chitosan functionalized Fe3O4-Au core shell nanoparticles have been prepared using a two-step wet chemical approach using NaBH4 as reducing agent for formation of Au in ethylene glycol. X-ray diffraction studies shows individual phases of Fe3O4 and Au in the as prepared samples with crystallite size of 5.9 and 11.4 nm respectively. The functionalization of the core-shell nanostructure with Chit...

BACKGROUND A targeted drug nanoparticle (NP) delivery system has shown potential as a possible cancer treatment. Given its merits, such as its selective distribution at tumor sites and its controllable drug release, drug-loaded NPs can be effectively delivered to selected organs and targeted cells, thus enhancing its antitumor efficiency and reducing its toxicity. METHODS We reported that hya...

in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

In this paper, we construct explicitly a NCS system ([Z4]) Ω T ∈ (H GL) ×5 over the Grossman-Larson Hopf algebra H GL ([GL] and [F]) of rooted trees labeled by elements of a nonempty W ⊆ N of positive integers. By the universal property of the NCS system (NSym,Π) formed by the generating functions of certain NCSF’s ([GKLLRT]), we obtain a graded Hopf algebra homomorphism TW : NSym → H GL such t...

where E`n denotes the group of `-torsion points of E. The Galois group GK = Gal(K̄/K) acts continuously on T` and therefore on V`. In a series of works ([5], [6], [8], [9]), Serre investigated the image, Γ`, of GK in GL(V`). If E has complex multiplication over C, Γ` is contained in a Cartan subgroup of GL(V`) (resp. the normalizer of a Cartan) if K contains (resp. does not contain) the endomorp...

There are several natural polymers such as carrageenan, alginate, chitin or chitosan that are classified as polysaccharides. One of the most promising is chitosan, deacetylated derivative of chitin, produced from shellfish wastes or fungi [15]. Irradiation of this polymer led the reduction of molecular weight by scission of glycosidic linkage. As compared to the conventional techniques, like ac...

BACKGROUND Glycemic index (GI) and glycemic load (GL) have been associated with coronary heart disease (CHD) risk in some but not all cohort studies. We therefore assessed the association of GI and GL with CHD risk in prospective cohorts. METHODS AND RESULTS We searched MEDLINE, EMBASE, and CINAHL (through April 5, 2012) and identified all prospective cohorts assessing associations of GI and ...
