BACKGROUND AND PURPOSE We have previously shown that female animals experience substantial protection from brain injury after reversible middle cerebral artery occlusion (MCAO) compared with their male or ovariectomized female counterparts. The reproductive steroid estrogen has been shown to provide neuroprotection from a variety of experimental insults, but the importance of progesterone as an...

BACKGROUND AND PURPOSE The importance of postmenopausal estrogen replacement therapy for stroke in females remains controversial. We previously showed that female rats sustain less infarction in reversible middle cerebral artery occlusion (MCAO) than their ovariectomized counterparts and that vascular mechanisms are partly responsible for improved tissue outcomes. Furthermore, exogenous estroge...

This paper uses income decomposition techniques to demonstrate the importance of livestock income in improving rural income distribution. It is based on three-year household panel data (1986 to 1989) from rural Pakistan. The paper first decomposes total income among five sources: agricultural, nonfarm, livestock, rental and transfer. This shows that livestock income is inequality-decreasing and...

Long-term depression (LTD) of synaptic efficacy has proven a difficult phenomenon to examine in vivo, despite the ease with which it is induced in a variety of in vitro preparations. Prior exposure to an acute stressful episode does however seem to enhance the capacity of the hippocampus to exhibit LTD in vivo in male animals. In the present experiments, we examined the capacity for low-frequen...
