In Vitro Ovicidal and Larvicidal Activity of Aqueous and Methanolic Extracts of Ziziphus Mucronata Barks Against Haemonchus Contortus

Haemonchus contortus is one of the most pathogenic nematode parasites in small ruminants’ worldwide. Anthelmintic resistance and high cost of drugs has prompted evaluation of medicinal plant extracts which can be used as alternative drugs.

The objective of this study was to evaluate in vitro ovicidal and larvicidal activity of aqueous and methanolic extracts of Ziziphus mucronata barks against H.

contortus stages isolated from a sheep in Kenya. Barks of Z. mucronata were collected from Chad, air-dried, ground and extracted with methanol and distilled water.

A Meta-Analysis of the Inclusion of Bio-Mos® in Milk or Milk Replacer Fed to Dairy Calves on Daily Weight Gain in the Pre-Weaning PeriodA Meta-Analysis of the Inclusion of Bio-Mos® in Milk or Milk Replacer Fed to Dairy Calves on Daily Weight Gain in the Pre-Weaning Period

This meta-analysis determines the effect of Bio- Mos®, a mannan-oligosaccharide, supplementation to preweaned dairy source calves on average daily weight gain (ADG) pre-weaning.

A literature search was performed and peerreviewed studies and abstract proceedings were included. Studies were included where Bio-Mos®- supplemented calves were compared to control calves and weights were measured pre-weaning.

A random effect meta-analysis was performed for overall effect and also comparing the effect stratified on type of liquid feed that the calves received. A total of 23 cohort studies performed in USA, United Kingdom, Brazil, Chile, the Czech republic, India, Japan, Peru, Poland, Spain and Turkey between 1993 and 2012 were included in the meta-analysis.

Upregulation of HSP70 Extends Cytoprotection to Fish Brain under Xenobiotic Stress

Xenobiotics are synthetic compounds foreign to the biological system. They often retain their qualities in the aquatic environment with the ability to cause oxidative stress in these organisms by activating the endogenous production of reactive oxygen species (ROS).

Overloading of the estuaries with contaminants for a longer period has an impact on fish production. The grey mullet (Mugil cephalus) is capable of concentrating contaminants and is considered suitable for biomarker studies.

Brain is an appropriate organ for the study of the effects of xenobiotics due to its morphological heterogeneity, metal accumulating capacity and susceptibility to histopathological damage by metals. Cells respond to stress in a variety of ways by activation of pathways that promote survival or apoptosis.
