In this study, N,N-Dimethyl-N-Octyl chitosan was synthesized. Nanoparticles containing insulin were prepared using PEC method and were statistically optimized using the Box-Behnken response surface methodology. The independent factors were considered to be the insulin concentration, concentration and pH of the polymer solution, while the dependent factors were characterized as the size, zeta po...

A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...

The effect of apocynin on the activity of arylamine N-acetyltransferases (NATs) in excised liver samples was examined using eighteen Sprague-Dawley rats. Three groups of six animals each were fed a normal diet alone or a treatment of 50 or 100 mg/kg/day of apocynin via gavages for eight (8) weeks. Chronic in vivo administration of apocynin led to significant (p < 0.001) reduction of in vitro li...

Peptidoglycan is an essential component of the cell wall of bacteria, including Mycobacterium tuberculosis, that provides structural strength and rigidity to enable internal osmotic pressure to be withstood. The first committed step in the biosynthesis of peptidoglycan involves the formation of uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) from uridine triphosphate (UTP) and GlcNAc-1-pho...

conclusion the minimum concentration of triolein emulsion required to increase vascular permeability adequately with minimal brain edema in a cat model was 0.5%. results the lesion hemispheres showed mild hyperintensity due to edema on t2-weighted images, and contrast enhancement on post-contrast t1-weighted images in cats of group 1-5. cers showed statistically significant differences between ...
