Abstract
To examine the roles of executive control and automatic activation in task switching, we manipulated foreknowledge as well as task transitions. In Experiments 1 and 2, performance with foreknowledge was faster than performance with no foreknowledge, but the amount of switch cost did not depend on foreknowledge. This result suggests that switch costs primarily reflect persisting activation rather than inadequate preparation. In Experiment 3, switch cost was greater with foreknowledge about task transition alone than with foreknowledge about both task transition and identity, suggesting that foreknowledge about specific task identity did allow preparation for a switched task. We argue that task repetition and foreknowledge effects are independent. Although foreknowledge allows preparation for both repeated and switched tasks, repeating the same task has benefits over task switching regardless of foreknowledge.

Abstract
Horseshoe kidney is a common renal fusion anomaly that is usually asymptomatic in adults. A horseshoe kidney was detected incidentally on Tc-99m DISIDA hepatobiliary scintigraphy performed to evaluate acute cholecystitis. The diagnosis was first suggested on hepatobiliary scintigraphy and confirmed by computed tomography.

Abstract
Human ability to switch from one cognitive task to another involves both endogenous preparation without an external stimulus and exogenous adjustment in response to the external stimulus. In an event-related functional MRI study, participants performed pairs of two tasks that are either the same (task repetition) or different (task switch) from each other. On half of the trials, foreknowledge about task repetition or task switch was available. On the other half, it was not. Endogenous preparation seems to involve lateral prefrontal cortex (BA 46/45) and posterior parietal cortex (BA 40). During preparation, higher activation increases in inferior lateral prefrontal cortex and superior posterior parietal cortex were associated with foreknowledge than with no foreknowledge. Exogenous adjustment seems to involve superior prefrontal cortex (BA 8) and posterior parietal cortex (BA 39/40) in general. During a task switch with no foreknowledge, activations in these areas were relatively higher than during a task repetition with no foreknowledge. These results suggest that endogenous preparation and exogenous adjustment for a task switch may be independent processes involving different brain areas.

Abstract
Hypercalcemia in accelerated phase of chronic myelogenous leukemia (CML) is very rare. Its pathogenesis is considered humoral hypercalcemia of malignancies mediated by parathyroid hormone-related protein (PTHrP). In severe hypercalcemia, calcifications in kidneys, skin, vessels, heart, and stomach may occur. Our two cases were admitted because of severe hypercalcemia in accelerated phase of CML. On Tc-99m methylene diphosphonate (MDP) bone scintigraphies, a marked tracer accumulation was seen in the lung, heart, stomach and kidney. We report increased tracer accumulation of multiple organs on Tc-99m MDP bone scintigraphy in two rare hypercalcemic patients with CML.

Abstract
IL-2-activated killer lymphocytes (LAK cells) secrete inflammatory cytokines such as interferon-gamma (IFN-gamma) and tumor necrosis factor alpha (TNFalpha) that can induce nitric oxide (NO) synthesis. We evaluated whether LAK cells could activate NO synthesis in human cancer cells. LAK cells and their culture supernatants induced NO synthesis in DLD-1 colon cancer cells in a dose-dependent manner. NO synthesis was inhibited completely by blocking antibodies to IFN-gamma, demonstrating a key role for this LAK cell cytokine in regulating NO synthesis. The addition of TNFalpha antibodies resulted in partial inhibition. Induction of iNOS mRNA and protein expression in DLD-1 cells was detected. Endogenous NO production inhibited DLD-1 cell proliferation and induced apoptosis, processes that were inhibitable by the NO synthase inhibitor N(G)-monomethyl-l-arginine. Our study has identified a novel, non-contact-dependent LAK cell cytotoxic mechanism: induction of growth inhibition and programmed cell death due to endogenous NO synthesis in susceptible human cancer cells.

Abstract
We evaluated the effect of antithrombin III (ATIII), a serine protease inhibitor (SERPIN), on induction of nitric oxide (NO) synthesis in murine peritoneal macrophages. Incubation of macrophages with ATIII plus interferon-gamma (IFN-gamma) but not ATIII alone induced nitrite accumulation (a metabolite of NO) in a dose-dependent manner. Expression of the inducible nitric oxide synthase isoform was confirmed by Western blot. NO synthesis was inhibited by NG-monomethyl-l-arginine, by complexing ATIII with thrombin or by rabbit anti-human ATIII antiserum. Addition of polymyxin B to macrophage cultures failed to inhibit ATIII/IFN-gamma-induced NO synthesis, excluding lipopolysaccharide contamination. 125I-ATIII bound to macrophages in a dose-dependent, specific, and saturable manner, with a Km of approximately 7.1 nM. Our results demonstrate that ATIII, but not ATIII/thrombin complex, acts to costimulate macrophage activation and NO synthesis via a novel receptor mediated mechanism, which may indicate a role for SERPINs in macrophage activation.

Abstract
UNLABELLED Gallium-67 has been a controversial tumor-imaging agent in nuclear medicine for decades. This controversy centers on why tumors are variable in gallium-avidity, whether 67Ga uptake is a transferrin-independent or dependent process, and whether tumors and normal tissues differ in mechanism of uptake. If the factors that control uptake of 67Ga were understood better, then efforts to improve oncologic imaging with 67Ga by increasing the tumor activity, or by decreasing the background, may be warranted. METHODS Conventional systems for evaluating the mechanism and control of 67Ga uptake have significant limitations. We have endeavored to circumvent these by developing a pair of transfected cell lines. One cell line has no transferrin receptor. In the other, the human transferrin receptor has been restored by transfection and is over-expressed constitutively, without the necessity to manipulate factors such as cell growth or iron content. The uptake of 67Ga, both as a citrate salt and as a gallium-transferrin complex, was examined in these pairs of cells in vitro. The effect of calcium and of soluble (ionic) iron concentration on 67Ga uptake also was determined. Tumors were grown as explants of these cells in nude mice and comparisons of uptake of 67Ga by these tumors in vivo were made. RESULTS The in vivo uptake of 67Ga is significantly increased in tumors in which the transferrin receptor is overexpressed, compared to those without a functional transferrin receptor. However, a notable amount of accumulation of 67Ga also occurs, both in vitro and in vivo, by a transferrin-independent route. In vitro experiments demonstrate that the uptake of 67Ga by the transferrin-independent route can be enhanced further to levels that equal or exceed those achieved by the transferrin-dependent route by increasing the content of calcium or iron salts in the incubation medium. CONCLUSION Significant transferrin-independent uptake of 67Ga occurs both in vitro and in vivo. This uptake can be stimulated further in vitro, suggesting that in vivo enhancement might also be possible to enhance the utility of the radiometal for tumor imaging.

Abstract
PURPOSE To evaluate the efficacy of selective arterial embolization in symptomatic renal angiomyolipoma (AML) and the change in angiomyogenic components during long-term follow-up after embolization. MATERIALS AND METHODS Fourteen adult patients with symptomatic AMLs underwent 16 selective arterial embolizations. The embolic materials used were absolute alcohol with (n = 5) or without (n = 3) iodized oil, Gianturco coils (n = 4), and polyvinyl alcohol foam powder with gelatin sponge (n = 2). Follow-up ultrasonography and computed tomography (CT) were performed in six and 14 patients, respectively. The effectiveness of selective arterial embolization was evaluated on the basis of the area of the angiomyogenic components in the AML on initial and follow-up images and clinical improvement. RESULTS All patients showed devascularization of the tumor on the postembolization angiograms. In 13 patients, clinical symptoms disappeared. The follow-up period was 7-72 months (mean, 33 months). One patient underwent nephrectomy at 7 months after embolization because of a large cystic lesion found at 1 month. In long-term CT follow-up (> or =12 months) in 12 patients, nearly all angiomyogenic components disappeared, but fatty components partially shrank with liquefactive necrosis in tumors. CONCLUSION Selective arterial embolization is an effective and safe treatment of AML. The angiomyomatous components crucial for the prevention of bleeding were very sensitive to the embolization.

Abstract
OBJECTIVES To evaluate if L-arginine: NO pathway is activated in tumor tissues during IL-2 therapy and to evaluate whether IL-2 induced NO synthesis represents an antitumor effector mechanism or an inhibitory factor against therapeutic effects of IL-2. METHODS Four groups [untreated control, NG-monomethyl-L-arginine (MLA) therapy only, IL-2 therapy only, IL-2/MLA therapy groups] of BALB/c mice were injected intraperitoneally with 2 x 10(8) Meth A tumor cells on day 0. MLA was administered subcutaneously with Alzet continuous infusion pumps on day 2. IL-2 therapy (180,000 IU s.c. every 12h for 5 days) was started on day 3. NO production within ascites tumors was assessed by measuring nitrite concentrations in cultures of ascites cells harvested on day 8. Survival and the rate of body weight increment of the mice were measured to evaluate therapeutic responses. Daily urinary nitrate excretion was monitored to demonstrate the effectiveness of MLA in inhibiting NO synthesis. RESULTS Nitrite production in supernatants of Meth A ascites cell cultures was 63 +/- 14 microM in IL-2 treated mice and 3.2 +/- 1.5 microM in untreated controls (p < 0.001). MLA prevented the IL-2 therapy induced increase in nitrite production. IL-2 therapy did not decrease the rate of body weight increment and marginally prolonged mean survival to 18.2 days, compared to 16.6 days in control mice (p = 0.255). MLA administration decreased the rate of body weight increment and prolonged mean survival of IL-2 treated mice (21.8 days, p = 0.001 versus IL-2 alone). Interestingly, the MLA treatment increased the rate of body weight increment and diminished the survival of control mice to 11.6 days (p = 0.003). MLA administration via Alzet continuous infusion pumps achieved approximately 60% suppression of urinary nitrate excretion by control mice. Subcutaneous IL-2 treatment strongly induced nitric oxide synthesis (up to 3.5 mumoles of urinary nitrate/ mouse/day). MLA also effectively suppressed IL-2 induced NO production. CONCLUSION L-arginine: NO pathway can be activated in malignant ascites by IL-2 therapy and NO synthesis functions as an inhibitory mechanism against IL-2 induced anti-tumor effects.

Abstract
PURPOSE To evaluate therapeutic effects and complications of a covered Gianturco stent for esophagorespiratory fistulae. MATERIALS AND METHODS Of 95 patients with esophageal carcinomas, 10 had esophagorespiratory fistulae and were treated with a silicone-covered Gianturco stent. The authors retrospectively assessed patients' food intake capacity and delayed problem of the stent. RESULTS All fistulae were occluded without immediate complications. Two patients could swallow all foods; four, most foods; three soft foods; and one, only liquids. Clinical problems occurred between 1 and 24 weeks in four patients: reopened fistula (n = 1), recurrent fistula (n = 1) (both patients were successfully treated with another esophageal stent), and dyspnea (n = 2) due to tracheal compression by stent and tracheal invasion by tumor (one patient was treated with a tracheal stent). CONCLUSION A silicone-covered modified Gianturco stent is effective for palliation of esophagorespiratory fistulae caused by esophageal cancer. Simultaneous use of a tracheal stent is recommended for extrinsic tracheal narrowing by the proximal tip of the stent and invasion by tumor.

Abstract
PURPOSE To evaluate the effectiveness of balloon dacryocystoplasty (DCP) in the treatment of complete and partial obstruction of the nasolacrimal system (NLS). MATERIALS AND METHODS Fluoroscopically guided balloon DCP was attempted in 57 eyes of 50 consecutive patients with complete obstruction of the NLS and 24 eyes of 22 patients with partial obstruction of the NLS. With nasal endoscopic guidance, a 0.018-inch guide wire was introduced through the superior punctum into the inferior meatus of the nasal cavity and pulled out through the nare with a hemostat. A deflated angioplasty balloon catheter was introduced in a retrograde direction over the guide wire, and the balloon was dilated. RESULTS Initial technical and clinical success was achieved in 29 of 57 eyes (51%) with complete obstruction and 17 of 24 eyes (71%) with partial obstruction. The 2-year cumulative clinical patency rates were 25% and 20% for partial and complete obstructions, respectively. The overall cumulative patency rate for all 81 eyes was 23%. CONCLUSION Balloon DCP is simple and safe but has high failure and recurrence rates.

Abstract
Adult presentation of congenital cystic adenomatoid malformation(CCAM) of the lung is so rare that only 5 cases have been reported in the literature to date. We report the case of a 19-year-old female with CCAM in the left lower lobe. Computed tomography showed a multilobulated cystic lesion with multiple air-fluid levels and also showed focal enhancement of the solid component in the eccentrical portion of the lesion. Thoracic aortogram and selected bronchial arteriograms show a slightly enlarged and tortuous bronchial artery feeding the multilobulated cystic lesion. We present the clinical and radiological features of our case with a brief review of the literature.
