The exact composition of milk varies by species to naturally or contamination. It is recognized that imbalance quantity of minerals and trace element being a serious health hazards especially for infants. Therefore, some essentials elements like K, Fe, Co and Pb (as a non essential element) have been determined in locally available milk powder of infant formulas, milk powder of growing children , processed milk or tetra pack milk of different brands and fresh milk samples (cow and buffalo) by sophisticated analytical techniques flame emissions spectroscopy (FES) and atomic absorption spectroscopy (AAS). The range of mean concentration of elements (K, Fe and Co) in milk samples was found to be 650.00-1500.00mg/l, 2.76-8.93mg/l and 0.05mg/l respectively. The levels of these elements in milk powder of infant formulas (1&2) were compared with the standards of FAO/WHO, recommended values of the Committee on Nutrition of the American Academy of Pediatrics, human milk and cow’s milk.

The reaction works under mild conditions and can be selectively employed in presence of phenolic groups and acid sensitive functionalities.

Isoquercetrin (1), 5-methylmellein (2), 2-hydroxy-3-O-β -primeveroside naphthalene-1,4-dione (3), Apigenin 7-O-glucuronide (4), Kaempferol-3-O-β-D-glucopyranosyl-(1→2)-α-L-rhamnopyranoside-7-O-α-L-rhamnopyranoside (5), 7-(1? hydroxyethyl)-2-(2″-hydroxyethyl)-3,4-dihydrobenzopyran (6) were isolated for the first time from Aerva javanica. Structural evidences were made by the extensive use of chemical and spectral studies. Different crude extracts (n-hexane, chloroform, ethyl acetate, methanol and water) and the all known isolated compounds were tested for their antimicrobial activity which displayed moderate to weak inhibitory activity.

Crystal structure of Shewanella oneidensis FMN-binding oxidoreductase was chosen as a template for homology modeling of Bovine Kappa-casein (CASK). The N- and C-terminal domains contain mainly α-helices connected by central β-Sheets with three-core α / β/ α Mur CD N-terminal domain. Multiple sequences showed considerable sequence similarity among the mammals family. The highly conserved residues of the template and target were also observed. Ramachandran plot and the energy graph indicated overall good and stable quality of the protein structure. The homology model was well superimposed on the corresponding units of the template. The overall topology and secondary structural elements were quite conserved. The ligands were found to be associated with the segment by hydrophilic, hydrophobic and protein by H2O interactions. The objective was to predict a 3D homology model on the basis of sequence and structural similarity that will fulfill the criteria of a good quality model.
