Yttria-stabilized zirconia (YSZ) is currently used in a variety of applications including oxygen sensors, fuel cells, coatings for semiconductor lasers, and buffer layers for high-temperature superconducting films. Thin films of YSZ have been grown by metal-organic chemical vapor deposition, electrochemical vapor deposition, pulse-laser deposition (PLD), electron-beam evaporation, and sputtering. In this investigation, PLD was used to grow thin films of YSZ on (100) MgO substrates. This system proves to be an interesting example of relationships between interfaces and extrinsic dislocations in thin films of YSZ.In this experiment, a freshly cleaved (100) MgO substrate surface was prepared for deposition by cleaving a lmm-thick slice from a single-crystal MgO cube. The YSZ target material which contained 10mol% yttria was prepared from powders and sintered to 85% of theoretical density. The laser system used for the depositions was a Lambda Physik 210i excimer laser operating with KrF (λ=248nm, 1Hz repetition rate, average energy per pulse of 100mJ).

SummaryA high incidence of post-discharge venous thromboembolism in orthopaedic surgery patients has been recently reported drawing further attention to the unresolved issue of the optimal duration of the pharmacological prophylaxis. We performed an overview analysis in order to evaluate the incidence of late occurring clinically overt venous thromboembolism in major orthopaedic surgery patients discharged from the hospital with a negative venography and without further pharmacological prophylaxis. We selected the studies published from January 1974 to December 1995 on the prophylaxis of venous thromboembolism after major orthopaedic surgery fulfilling the following criteria: 1) adoption of pharmacological prophylaxis, 2) performing of a bilateral venography before discharge, 3) interruption of pharmacological prophylaxis at discharge in patients with negative venography, and 4) post-discharge follow-up of the patients for at least four weeks. Out of 31 identified studies, 13 fulfilled the overview criteria. The total number of evaluated patients was 4120. An adequate venography was obtained in 3469 patients (84.1%). In the 2361 patients with negative venography (68.1%), 30 episodes of symptomatic venous thromboembolism after hospital discharge were reported with a resulting cumulative incidence of 1.27% (95% C.I. 0.82-1.72) and a weighted mean incidence of 1.52% (95% C.I. 1.05-1.95). Six cases of pulmonary embolism were reported. Our overview showed a low incidence of clinically overt venous thromboembolism at follow-up in major orthopaedic surgery patients discharged with negative venography. Extending pharmacological prophylaxis in these patients does not appear to be justified. Venous thrombi leading to hospital re-admission are likely to be present but asymptomatic at the time of discharge. Future research should be directed toward improving the accuracy of non invasive diagnostic methods in order to replace venography in the screening of asymptomatic post-operative deep vein thrombosis.

Objective: To study the significance of serum magnesium levels during COPD exacerbation and stability.Materials & Methods: The patient population consisted of all patients of COPD admitted as acute exacerbation as defined by the Anthonisens criteria, from June 2006 to may 2008. Same patients one month post discharge presenting to the OPD for routine check up as stable COPD served as controls. Results: A total number of 77 patients of COPD presenting as acute exacerbation were included in the study. The incidence of Hypomagnesaemia was 33.8% at admission; 5% at discharge and 4% at one month of post discharge in COPD patients. The mean serum magnesium levels were significantly lower in cases than controls (1.88±0.67mg/ dl V/S 2.3±0.36mg/dl; p<0.0001). Also, hypomagnesemia was present in higher number of cases (22/77, 33.8%) compared to controls, 3/75, 4.0%; (p<0.0001). Patients of COPD with acute exacerbation and hypomagnesemia, had longer duration of symptoms and had advanced stage III of COPD (p<0.001); and had raised mean corpuscle volume (p<0.045) and longer hospital stay (p<0.008).  Conclusion: We conclude COPD exacerbation is associated with hypomagnesemia. The duration of symptoms of more than 8 days, advanced stage of COPD (stage III) and raised MCV were associated with hypomagnesemia. We recommend to monitor serum magnesium levels in COPD patients with acute exacerbation at the time of admission and during their stay in the hospital.J Med Sci.2010;13(1);15-19
