Fasciola hepatica secretes cathepsin L proteases that facilitate the penetration of the parasite through the tissues of its host, and also participate in functions such as feeding and immune evasion. The major proteases, cathepsin L1 (FheCL1) and cathepsin L2 (FheCL2) are members of a lineage that gave rise to the human cathepsin Ls, Ks and Ss, but while(More)
Rats implanted with Yoshida ascites hepatoma (YAH) show a rapid and selective loss of muscle protein due mainly to a marked increase (63-95%) in the rate of protein degradation (compared with rates in muscles of pair-fed controls). To define which proteolytic pathways contribute to this increase, epitrochlearis muscles from YAH-bearing and control rats were(More)
Previous studies have demonstrated that the penetrating weak base NH4Cl and the anesthetics procaine and urethane disrupt the normal attachment of cortical granules to the cortex of the sea urchin egg. Hylander and Summers (1981: Dev. Biol. 86:1-11) hypothesized that this effect may be caused by a pH-induced polymerization of cortical actin. We have tested(More)
This study aimed to identify whether genetic manipulation of four systems implicated in the pathogenesis of depression converge on shared molecular processes underpinning depression-like behaviour in mice. Altered 5HT function was modelled using the 5-HT transporter knock out mouse, impaired glucocorticoid receptor (GR) function using an antisense-induced(More)
An alarming result was noted in conjunction with a nipple stimulation contraction stress test. In a 42-week pregnant woman with suspected postmaturity, gentle self-stimulation of the right nipple through the clothing for one to 1.5 minutes caused the sudden onset of uterine hypercontractility, increased uterine tone, and severe fetal bradycardia. The(More)
Spectrin has been implicated in a variety of different processes during late embryogenesis, after transcription of the zygotic genome has been activated. However, relatively little is known about the role of maternally derived spectrin during the early cleavage divisions that give rise to a multicellular embryo. To investigate the role of spectrin in early(More)
