Responses of the ear to low-frequency and infrasonic sounds have not been extensively studied. Understanding how the ear responds to low frequencies is increasingly important as environmental infrasounds are becoming more pervasive from sources such as wind turbines. This study

Previous research demonstrated that sperm motility is dependent upon mitochondrial calcium cycling. Thus, sperm are inactivated when extracellular calcium ions are chelated. Mitochondrial calcium cycling, however, is driven by extracellular sodium ions. The hypothesis that sperm inactivation is subject to

Envenomation by Australian copperheads results mainly in muscle paralysis largely attributed to the presence of postsynaptic α-neurotoxins. However, poorly reversible neurotoxic effects suggest that these venoms may contain snake presynaptic phospholipase A2 neurotoxins (SPANs) that irreversibly inhibit neurotransmitter release. Using
