Abstract
The higher oxidation state of iron, i.e. Fe(VI), was exploited to treat the synthetic wastewater containing Zn(II)-NTA. The decomposition of Zn(II)-NTA by Fe(VI) was investigated with the help of analytical data obtained for the change in Fe(VI) concentration, dissolved organic carbon (DOC) and total soluble Zn(II) concentration as a function of time at various concentrations of Zn(II)-NTA and at constant Fe(VI) concentration. The UV-Visible data was used to explain the reaction kinetics for redox reactions between Fe(VI) and Zn(II)-NTA. The pseudo-first-order rate constant was calculated keeping the Zn(II)-NTA concentration in excess and hence the overall second-order-rate constant was obtained. Fe(VI) reduction was almost unaffected with the 1000 times increase in ionic strength (NaNO3), as well as in the presence of completely oxidized background electrolytes. However, Fe(VI) reduction was greatly affected in the presence of both SO3(2-) and NO2(-) especially at higher concentrations, indicating a competitive reduction took place between Zn(II)-NTA and Na2SO3 or NaNO2 in the Fe(VI) treatment. These results were again supported by the dissolved organic carbon observations since relatively very low removal of the dissolved organic carbon occurred in the presence of Na2SO3 and NaNO2.

Abstract
CD8(+) memory T cells endanger allograft survival by causing acute and chronic rejection and prevent tolerance induction. We explored the role of CD27:CD70 T-cell costimulatory pathway in alloreactive CD8(+)/CD4(+) T-cell activation. CD27-deficient (CD27(-/-)) and wild-type (WT) B6 mice rejected BALB/c cardiac allografts at similar tempo, with or without depletion of CD4(+) or CD8(+) T cells, suggesting that CD27 is not essential during primary T-cell alloimmune responses. To dissect the role of CD27 in primed effector and memory alloreactive T cells, CD27(-/-) or WT mice were challenged with BALB/c hearts either 10 or 40 days after sensitization with donor-type skin grafts. Compared to WT controls, allograft survival was prolonged in day 40- but not day 10-sensitized CD27(-/-) recipients. Improved allograft survival was accompanied by diminished secondary responsiveness of memory CD8(+) T cells, which resulted from deficiency in memory formation rather than their lack of secondary expansion. Chronic allograft vasculopathy and fibrosis were diminished in CD27(-/-) recipients of class I- but not class II-mismatched hearts as compared to WT controls. These data establish a novel role for CD27 as an important costimulatory molecule for alloreactive CD8(+) memory T cells in acute and chronic allograft rejection.

Abstract
BACKGROUND Lacking a long-term continuous intravenous infusion device for experimental animals is the biggest obstacle to constructing an allogenic small bowel transplantation rejection model. OBJECTIVE To establish a rat heterotopic small bowel transplantation model with the use of a swivel device for intravenous transfusion. METHODS The randomized block design of controlled observations included 90 inbred male F344/NCrl BR rats as donors and 90 LEW/Crl rats as recipients. On the basis of body weight, the rats were divided into three groups each with 30 pairs of rats. Group 1, the control group, underwent small bowel transplantation. Group 2, the transfusion group, received small bowel transplantation and continuous infusion of parenteral nutrient solution. Group 3, the tacrolimus (FK506) treatment group, received small bowel transplantation, continuous infusion of parenteral nutrient solution, and intravenous injection of FK506. The general status and survival time of transplanted rats were observed for 5 weeks. RESULTS The operative success rate was 100%. The survival rate was 83.3% (25/30) in the control group; and 96.7% (58/60) in groups 2 and 3 (P = .039). The mean survival time of the FK506 group was 22.1 +/- 13.4 days, which was significantly higher than that in the transfusion group (10.4 +/- 2.9 days, P = .023). CONCLUSION The simple, practical swivel intravenous infusion device provided treatment for more than 30 days, a useful tool for heterotopic segmental small bowel transplantation.

Abstract
CONTEXT Studies in humans and animals indicate that estrogen negative feedback occurs at the level of the hypothalamus, but it is unclear whether estrogen also exerts an inhibitory effect directly at the pituitary. OBJECTIVES The aim of the study was to determine whether estrogen has a direct negative feedback effect at the pituitary and whether this varies with aging. DESIGN AND SETTING A GnRH antagonist and graded doses of GnRH were used to isolate pituitary responsiveness before and after estrogen administration in Clinical Research Center studies at an academic medical center. SUBJECTS Subjects were healthy postmenopausal women aged 48-56 yr (n = 8) or 70-75 yr (n= 8). INTERVENTIONS A suppressive dose of the NAL-GLU GnRH antagonist was administered, followed by graded doses of GnRH before and after 1 month of estrogen administration. RESULTS LH and FSH responses to GnRH decreased after estrogen administration (P = 0.01 and P = 0.0001, respectively). The ratio of FSH to LH amplitudes decreased in response to estrogen (P = 0.04) indicating a greater sensitivity of FSH than LH to inhibition by estrogen. The inhibitory effect of estrogen on FSH was attenuated with aging (P = 0.02), but was maintained for LH (P = 0.4). CONCLUSIONS Studies that control for endogenous GnRH and estradiol demonstrate a direct pituitary site of estrogen negative feedback on LH and FSH responsiveness to GnRH in women. The effect of estrogen on FSH responsiveness is greater than on LH and is attenuated with aging. These studies indicate that estrogen negative feedback occurs directly at the pituitary and contributes to the differential regulation of FSH and LH secretion.

Abstract
To analyze the in vivo structure of antigen-specific immunological synapses during an effective immune response, we established brain tumors expressing the surrogate tumor antigen ovalbumin and labeled antigen-specific anti-glioma T cells using specific tetramers. Using these techniques, we determined that a significant number of antigen-specific T cells were localized to the brain tumor and surrounding brain tissue and a large percentage could be induced to express IFNgamma when exposed to the specific ovalbumin-derived peptide epitope SIINFEKL. Detailed morphological analysis of T cells immunoreactive for tetramers in direct physical contact with tumor cells expressing ovalbumin indicated that the interface between T cells and target tumor cells displayed various morphologies, including Kupfer-type immunological synapses. Quantitative analysis of adjacent confocal optical sections was performed to determine if the higher frequency of antigen-specific antiglioma T cells present in animals that developed an effective antitumor immune response could be correlated with a specific immunological synaptic morphology. Detailed in vivo quantitative analysis failed to detect an increased proportion of immunological synapses displaying the characteristic Kupfer-type morphology in animals mounting a strong and effective antitumor immune response as compared with those experiencing a clinically ineffective response. We conclude that an effective cytolytic immune response is not dependent on an increased frequency of Kupfer-type immunological synapses between T cells and tumor cells.

Abstract
We present two cases of children who developed compartment syndrome after upper limb fractures. Morphine patient-controlled analgesia was used in a bolus-only mode for analgesia (bolus 20 μg/kg, five minute lockout and hourly limit of 150 μg/kg). An increase in patient-controlled analgesia use was observed up to 12 hours before the decision was made to proceed to fasciotomy but neither child exceeded the hourly limit or had an excessive increase in pain scores. Clinical risk factors for compartment syndrome should be identified and appropriate monitoring instituted. A subtle increase in patient-controlled analgesia use may be an early indicator of impending compartment syndrome before classical signs such as reporting of pain, pallor, paraesthesiae, paralysis and pulselessness develop. These cases and review of the literature suggest techniques which may assist earlier diagnosis of compartment syndrome include setting a more conservative hourly limit of morphine patient-controlled analgesia such as 80 to 100 μg/kg/hour and graphing of patient-controlled analgesia demands and boluses, pain scores at rest and pain scores with passive flexion and extension of digits. These practices could identify trends that pain or analgesia requirement is increasing leading to earlier diagnosis of compartment syndrome.
