Matrix metalloproteinases (with accent to collagenases)
Matrix metalloproteinases (MMPs) are a major group of enzymes that regulate cell–matrix composition.The MMPs are zinc-dependent endopeptidases known for their ability to cleave one or several extracellular matrix (ECM) constituents, as well as nonmatrix proteins. This review focuses on structural and functional elements of MMPs, and their roles in physiological and pathological processes, in which...

Enumeration and identification of Coliform bacteria from raw milk in Khartoum State, Sudan
To determine the most probable number (MPN) of Coliform and to identify the Coliform bacteria present in the raw milk in the three geographical areas of Khartoum state. Six hundred and forty four raw milk samples were collected during the period between April 2008 to February 2009. The Coliformlimits in the raw milk accepted internationally are less than 100 cell/ml. About 51.3% of the samples...

Breed characteristics in Iranian native goat populations
Investigation of genetic relationship among populations was traditionally based on the analysis of allele frequencies at different loci. The aim of this study was to analyze, the genetic diversity and variability of three native Iranian goat populations (Raeini, Korki Jonub Khorasan and Lori) through the use of 13 microsatellite markers. The 13 tested loci were all polymorphic in the three...

Preliminary studies on the damage symptoms and the spatial distribution of an emerging insect pest, Mecocorynus sp. (Coleoptera: Anthribidae) on cashew in Ghana
Cashew (Anacardium occidentale Linn.) has become a very important non-traditional tree crop in Ghana. The crop is, however, infested by numerous insect pests at different stages of its growth. Knowledge of the insect complexity associated with the tree is essential for developing pest control strategies for the crop. Following a reported outbreak of an unknown pest by officials of Ministry of Food and...
