background lactoferrin is a multipurpose protein of the transferrin domestic. it is a spherical glycoprotein with a molecular weight of about 80 kda which is widely found in secretory discharges, such as milk, saliva, tear, and nasal secretions. lactoferrin is also found in secondary granules of polymorphonuclear leukocytes (pmn) and is released by some acinar cells. it also shows antibacterial...

in depth interaction studies between calf thymus deoxyribonucleic acid (ct-dna) and a series of four structurally relative palladium(ii) complexes [pd(en)(hb)](no3)2 (a-d), where en is ethylenediamine and heterocyclic base (hb) is 2,2'-bipyridine (bpy, a); 1,10-phenanthroline (phen, b); dipyridoquinoxaline (dpq, c) and dipyridophenazine (dppz, d) (figure 1), were performed. these studies h...

background: acanthamoeba castellanii is the important cause of amoebic keratitis in iran. the key molecule in pathogene­sis of acanthamoeba keratitis is mannose binding protein (mbp) led to adhesion of amoeba to corneal epithelium. subse­quent to adhesion other cytopathic effects occur. the goal of this study was to identify the molecular characterization of a gene encoding mbp in an iranian is...

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...

following our previous presentation of a new three-fold symmetry for derivation of the magic numbers of nuclei based upon a quark state model of nuclei, here the nuclear binding energy is obtained from such new perspective. from this point of view, since each nucleon is made of three quarks, the binding energy of nuclei contains a volume term proportional to 3a (a is mass number). by considerin...

effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...

in this paper, using monte carlo fortran code, we have obtained the binding energies for three different systems of diquark–antidiquark in distances from 0.01 to 15 nm. in [0.1 - 15] nm interval, we made use of coulomb potential because in this interval, strong interaction is negligible. we have compared the binding energies of the systems with one another. the results of these comparisons were...

if we think of the graph as modeling a network, the vulnerability measure the resistance of the network to disruption of operation after the failure of certain stations or communication links. many graph theoretical parameters have been used to describe the vulnerability of communication networks, including connectivity, integrity, toughness, binding number and tenacity.in this paper we discuss...

the interaction of brilliant green with herring sperm dna was investigated in detail by spectrometric methods in γ-cyclodextrin systems. on the condition of physiological ph, brilliant green prefers to form the 1:1 inclusion complex with γ-cyclodextrin.all the evidences indicated that the binding modes between γ-cyclodextrin-brilliant green and dna were grooving binding and partial non-classica...
