## Abstract ABSTRACT The mammalian sperm acrosome reaction (AR) is a fusion and fenestration of sperm head membranes which is essential for fertilization. Our earlier work demonstrated that arachidonic acid could stimulate the AR 15 min after addition to hamster sperm capacitated by incubation for

When 5-aminolevulinic acid ( ALA ) is administered topically, intravenously or intraperitoneally to tumor-bearing animals or humans, tumor selective production of protoporphyrin IX ( PpIX ) is frequently observed. Several biophysical, biochemical and physiological factors explain this tumor selectiv
## Abstract The herbicide 2,4,5 trichlorophenoxy acetic acid (245T) at concentrations from 0.5 to 0.9 mM, was found to inhibit respiration and then growth in exponentially growing cultures of __Tetrahymena pyriformis__. Cell division was stopped for periods up to 60 minutes after which the cells re
The acid unfolding of deoxymyoglobin (deoxyMb) from the native (N) form to the unfolded (U) form proceeds through at least two spectroscopically distinct heme intermediates. The 426-nm absorbing heme intermediate ( I-form) occurs in the pH Γ 3.5-4.5 range. In the I-form, the iron-proximal histidine
