Treatment of grass leaves with either a purified pectin lyase of Aspergillus japonicus or a purified xylanase of Trichoderma viride could lead to the isolation of some single leaf cells. However, a mixture of pectin lyase and xylanase brought about more rapid isolation of single cells than did either of the two enzymes alone, indicating a synergistic effect. Analysis of the components released ...

Uncoated surfaces of high index glasses when cemented to form lens doublets have inferior antireflection properties to doublets of low index glass. This can be overcome by the application of a single layer coating of aluminum oxide prior to cementing.

Introduction: Aseptic loosening of the femoral component continues to be a major long-term complication across a wide range of designs in total hip arthroplasty (THA). Early debonding at the stem/cement interface is emerging as an alarming problem [1] with the roughened surface finishes currently popular in clinical practice. The onset of stem/cement interface radiolucency is commonly regarded ...
