Abstract
We collected 50 three-toed box turtles (Terrapene carolina triunguis) from 9 counties of Arkansas and 4 counties of Oklahoma, and examined their feces for coccidial parasites. Nine of 24 (38%) turtles from Arkansas and 8 of 26 (31%) from Oklahoma were found to be passing oocysts of Eimeria ornata. This represents two new geographic distributional records for this coccidian. Measurements of individual isolates of E. ornata as well as morphological characteristics are provided with comparison to its original description and to another Terrapene coccidian, Eimeria carri. In addition, we noted an adelid pseudoparasite being passed by a single T. c. triunguis from Oklahoma that likely represents a parasite of arthropods.

Abstract
Cholecystokinin-2 (CCK-2) receptors, overexpressed in cancer types such as small cell lung cancers (SCLC) and medullary thyroid carcinomas (MTC), may serve as targets for peptide receptor radionuclide imaging. A variety of CCK and gastrin analogues has been developed, but a major drawback is metabolic instability or high kidney uptake. The minigastrin analogue PP-F11 has previously been shown to be a promising peptide for imaging of CCK-2 receptor positive tumors and was therefore further evaluated. The peptide was conjugated with one of the macrocyclic chelators DOTA, NOTA, or NODAGA. The peptide conjugates were then radiolabeled with either (68)Ga, (64)Cu, or (111)In. All (radio)labeled compounds were evaluated in vitro (IC50) and in vivo (biodistribution and PET/CT and SPECT/CT imaging). IC50 values were in the low nanomolar range for all compounds (0.79-1.51 nM). In the biodistribution studies, (68)Ga- and (111)In-labeled peptides showed higher tumor-to-background ratios than the (64)Cu-labeled compounds. All tested radiolabeled compounds clearly visualized the CCK2 receptor positive tumor in PET or SPECT imaging. The chelator did not seem to affect in vivo behavior of the peptide for (111)In- and (68)Ga-labeled peptides. In contrast, the biodistribution of the (64)Cu-labeled peptides showed high uptake in the liver and in other organs, most likely caused by high blood levels, probably due to dissociation of (64)Cu from the chelator and subsequent transchelation to proteins. Based on the present study, (68)Ga-DOTA-PP-F11 might be a promising radiopharmaceutical for PET/CT imaging of CCK2 receptor expressing tumors such as MTC and SCLC. Clinical studies are warranted to investigate the potential of this tracer.

Abstract
BACKGROUND/AIMS To investigate the effect of increased CO2 levels on flicker defined stimuli. METHODS The sensitivity of two flicker defined tasks was measured in nine healthy, trained observers using the Flicker Defined Form (FDF) stimulus of the Heidelberg Edge Perimeter (HEP; Heidelberg Engineering) and Frequency Doubling Technology (FDT) stimulus of the Matrix perimeter (Carl Zeiss Meditec) during normoxia and 15% hypercapnia (end-tidal CO2 increased by 15% relative to baseline). HEP-FDF and Matrix-FDT sensitivities were analysed for the global field, superior and inferior hemifields and at specific matched eccentricities, using repeated measures analysis of variance. The main effect of hypercapnia on flicker sensitivity was analysed using regression models. RESULTS Higher flicker sensitivity outcomes with increasing CO2 values were found for HEP-FDF and Matrix-FDT with a statistically significant main effect for HEP-FDF global, superior and inferior hemifields (p<0.01 for all) as well as 6°, 18°, 12° and 24° eccentricities (p=0.03, 0.04, 0.01, 0.05, respectively). When comparing mean sensitivity values between normocapnia and hypercapnia conditions, no statistically significantly different results were found for HEP-FDF and Matrix-FDT (p>0.05). CONCLUSIONS As CO2 levels were increased in healthy young individuals, there was an associated increase in visual sensitivity that was only significant for HEP-FDF stimuli, highlighting the different mechanisms involved in processing each of HEP-FDF and Matrix-FDT stimuli. Mean visual sensitivity outcomes were found to be similar for normocapnia and hypercapnia suggesting that a capability to compensate for a mild and stable increase in systemic CO2 levels may exist.

Abstract
Serum placental alkaline phosphatase (PLAP)-type immunoreactivity was measured in 190 women with epithelial ovarian malignancy, 27 women with borderline ovarian cancer and 334 control subjects with non-neoplastic or benign gynaecological disease. Smoking, ABO blood group and menopausal status affect serum concentrations of PLAP and results were corrected for these. Circulating levels were elevated in patients with cancer and increased with stage. Levels were unaltered in borderline ovarian disease. Two-year stage corrected survival analysis demonstrated a significant worsening of prognosis in patients with serum PLAP-type levels greater than the 100th centile for controls.

Abstract
Objective: Modified ultrafiltration (MUF) reduces some of the complications associated with cardiopulmonary bypass (CPB) in pediatric cardiac surgery. However, we have observed hypokalemia and hypomagnesemia in children when MUF is used. Such alterations may elicit severe arrhythmias in the postoperative period. To date, no studies have focused on the effects MUF may have in plasma levels of potassium (K) and magnesium (Mg). The objective of our study was to determine if there is any variation in plasma levels of K (plK) and Mg (plMg) after MUF in children undergoing cardiac surgery with CPB. Patients: Sixteen children scheduled for cardiac surgery with CBP and MUF were prospectively studied. Anesthetic, CPB and MUF management were standardized for all patients, the latter lasting for 10 minutes. Results: Plasma K average levels before and after MUF were 4.16 mmol/L and 3.58 mmol/L, respectively. The average plasma Mg levels before and after MUF were 4.82 mmol/L and 4.81 mmol/L, respectively. Conclusions: The plasma level of K is reduced by 13.7% after MUF (p<0.0001). The reduction in Mg at the same period of time was not statistically significant (p<0.970).
