TL;DR: The effects of naloxone in opiate-naive rats are possibly due to blockade of an endogenous morphine-like substance (endorphin) and time-dependent changes in amplitudes of the averaged evoked responses.

TL;DR: It is concluded that cathepsin D is an important factor that may contribute to the pathogenesis of endometriosis, possibly by promoting digestion of extracellular matrix proteins.
Abstract: To assess the release of the proteolytic enzyme cathepsin D in endometriosis, concentrations in peritoneal fluid and serum were measured by ELISA in 54 women with (n = 33) and without (n = 21) endometriosis. Surgery was scheduled in either the proliferative or secretory phase of the menstrual cycle. The concentrations of cathepsin D in the peritoneal fluid were markedly elevated in the endometriosis patients (median 58 ng/ml, interquartile range 0-166 ng/ml) as compared to the controls (5 ng/ml, 0-86 ng/ml), especially in women with late stage disease (n = 19, stages III/IV) and in those not undergoing gonadotrophin-releasing hormone (GnRH) agonist therapy (n = 15). No significant difference was determined in cathepsin D concentrations of the serum from women with and without endometriosis. We conclude that cathepsin D is an important factor that may contribute to the pathogenesis of endometriosis, possibly by promoting digestion of extracellular matrix proteins. These results have implications for the therapeutic efficacy of GnRH agonists.

TL;DR: It is concluded that the parameters measured by CT and 123IMP-SPECT in patients with acute cerebral infarction cannot reliably be used to predict clinical outcome.
Abstract: A multicenter prospective study was performed in 49 patients with 77 regions of cerebral infarction. Each patient was evaluated in the acute (0-5 days) and subacute (6-17 days) phases by (1) clinical neurologic examination, (2) CT scans, and (3) N-isopropyl-p-123I-iodoamphetamine (123IMP) single-photon emission CT (SPECT) scans. The abilities of the scans to (1) detect a lesion and (2) predict the clinical outcome were assessed. For lesion detection, 123IMP-SPECT was superior to CT in the first 2 days, but the scans were equally effective 3-5 days after onset. In the subacute phase, IV contrast-enhanced CT was superior to 123IMP-SPECT and unenhanced CT. The clinical outcome was only mildly correlated with the results of the acute and subacute 123IMP-SPECT and the acute CT scans. Reduction in lesion size on the subacute scans did not correlate with clinical improvement. We conclude that the parameters measured by CT and 123IMP-SPECT in patients with acute cerebral infarction cannot reliably be used to predict clinical outcome. 124I contamination of 123IMP and the use of low-energy collimators may have decreased lesion detectability.
