In vitro and in vivo acaricidal efficacy study of amitraz and diazinon against some tick species infesting Camelus dromedarius around Jigjiga, Eastern Ethiopia
Tick infestation is considered to be a major concern as ticks cause widespread distress, act as vectors of disease and affect the economic conditions of livestock-rearing. Although the use of chemicals is still the most effective method of tick control, uncontrolled applications may have accelerated the emergence of tick resistance to several active ingredients available. The present work estimated the efficacy of two...

Nitrite, oxidation and color during shelf life of jerked beef
The present study aims to characterize the shelf life time effect on residual levels of nitrite, lipid oxidation and color of commercial jerked beef. Twelve samples from four different manufacturers, were collected in three shelf time slots (0 to 60, 61 to 120 and 121 to 180 days) and their nitrite concentration, lipid oxidation (TBARS) and color parameters (colorimeter and preference by ranking test) were assessed. The...

In vitro antioxidant, cytotoxic and phytochemical studies of Clinacanthus nutans Lindau leaf extracts
An increasing demand for natural additives has drawn more interest from consumers due to their relatively safe and wide acceptance. The present work examines the potential of different solvent system of Clinacanthus nutans Lindau leaves as a source of natural antioxidant. We also screened for its phytochemical constituents and cytotoxicity toward breast cancer cell. In vitro antioxidant activity of the n-hexane,...
