Input: Consider Input: Abstract: High-volume intravenous urography was performed in 63 women with surgically proven endometriosis. Subtle abnormalities were found in 15.9% of these women. No patient had urologic symptoms, and there was no evidence of hydroureter or ureteral obstruction on the IVP. Long-term follow-up study will be required to determine whether or not these lesions will progress and cause ureteral obstruction.

Input: Consider Input: Abstract: A medical and engineering study was made of 1074 car accidents involving 2520 vehicle occupants. The injuries they sustained were correlated with details of the crash and with contact points inside the cars. Where possible the forces which were generated in the crash were estimated and related to the injuries. In all, 39 car occupants suffered femoral shaft fracture, with an incidence of 1.7% and 0.8% for front and rear seat occupants respectively. Of these, 31 had associated injuries to other regions of the body; these were the cause of 13 of the 14 deaths in this group. Associated injuries were more severe in car occupants who were not wearing seat belts but the incidence of femoral fracture was not significantly different. The mean velocity change (delta-V) causing femoral fracture was 26 mph (42 km/h) and there was a higher incidence of femoral shaft fracture when delta-V was over 30 mph. Estimates of forces needed to cause fracture were higher than those found in cadaver studies. The time to union of femoral fractures did not correlate with the severity of the crash but was longer (mean 19 weeks) than the average for other femoral fractures.

Input: Consider Input: Abstract: We have previously demonstrated that T3 increases adenylate cyclase activity in rat thymocyte plasma membranes by a mechanism that is calcium dependent. In the present studies we have examined whether calmodulin participates in this response to T3. Initial experiments provided evidence that calmodulin is involved in regulating the activity of the guanyl nucleotide-dependent adenylate cyclase in this tissue. Thus, compared with findings in freshly prepared membranes, dialysis of thymocyte plasma membrane preparations for 20 h at 4 C decreased their calmodulin concentrations from an initial value of approximately 600 ng/100 micrograms protein by about 50% and decreased adenylate cyclase activity by approximately 80%. Although storage of the same preparations under comparable conditions resulted in no change in calmodulin content, it caused an approximate 30% decrease in adenylate cyclase activity. Addition of calmodulin had no effect on adenylate cyclase activity in fresh or stored membrane preparations, but produced a dose-dependent increase in enzyme activity in preparations that had been dialyzed. Further, when added to freshly isolated membranes, three calmodulin antagonists, trifluoperazine, calmidazolium, and calmodulin antibodies, all produced a concentration-dependent inhibition of adenylate cyclase activity, and this was completely reversed in all cases by the addition of high concentrations of exogenous calmodulin. The stimulation of guanyl nucleotide-dependent adenylate cyclase activity that T3 induced in fresh membrane preparations was present in membranes that had been stored, but was absent in those that had been dialyzed. In addition, the response to T3 in fresh membranes was inhibited or abolished by all three calmodulin antagonists. Both in dialyzed membranes and in the presence of antagonists, the response to T3 was restored by the addition of exogenous calmodulin. We conclude that calmodulin influences the activity of the guanyl nucleotide-dependent adenylate cyclase in rat thymocytes and ultimately mediates the stimulation of enzyme activity that T3 produces. Such mediation very likely explains the calcium-dependent nature of the stimulatory effect of T3 on thymocyte adenylate cyclase activity.
