In a lunge and split squat, one leg is forward and in front of you, the other leg is behind you. In a lunge, the rear leg is engaged in the exercise. In a split squat, the rear leg is at rest throughout the exercise -- it is not engaged. This is the key difference between the two exercises. A split squat focuses on the exercise entirely on one leg.
Cephalosporin, any of a group of Î²-lactam antibiotics that inhibit the synthesis of a structural component of the bacterial cell wall. The cephalosporins were first isolated from cultures of the fungus Cephalosporium acremonium. Modifications of the Î²-lactam ring have resulted in more than 20 derivatives with a range of antibacterial properties. The cephalosporins are often used as an alternative in patients who are sensitive to penicillin.
Some 3rd-generation cephalosporins have relatively poor activity against gram-positive cocci. Oral cefixime and ceftibuten have little activity against S. aureus and, if used for skin and soft-tissue infections, should be restricted to uncomplicated infections due to streptococci.
