Background: The appropriateness of using serum levels of procalcotonin (PCT) for early diagnosis of newborn sepsis is still controversial. Therefore, the objective of the present study was to compare the usefulness of PCT with those of serum levels of C-reactive protein (CRP) and white blood cell (WBC) counts in the diagnosis and response to treatment of neonatal sepsis. Methods: A total of 47 ...

This study was done to evaluate the antimicrobial and antioxidant effects of nisin Z (0.02 %) and sodium benzoate (1.5 and 2.5 %) in vacuum packed Caspian Kutum (Rutilus frisii) fillet stored at 4°C. Microbial changes [aerobic plate counts (APC), psychrotrophic counts (PTC) and lactic acid bacteria] and chemical indices [peroxide value and total volatile basic nitrogen (TVB-N)] were determined ...

background: the present study was carried out to track and calculate biomagnification factor (bmf) of total mercury (t-hg) between two different trophic levels (i.e., plankton and a planktivorous fish) in a fresh water grazing food chain. methods: experimental organisms were planktonic biomass and silver carp (hypophthalmichthys molitrix) as a planktivorous fish. silver carp samples were obtain...

crop rotation affect on crop nitrogen uptake and nitrogen use efficiency (nue). crop rotations with high nue decrease energy use and increase level of sustainability in agro ecosystems. the objectives of this research were to determine the suitable double cropping system for enhancing nue and evaluate the effects of crop rotation, n fertilizer rate and return of crop residue on nue. this study ...
