BACKGROUND Patients with a history of solid organ transplantation(SOT)or hematopoietic stem cell transplantation(HSCT)are at an increased risk of developing post-transplant lymphoproliferative disorder(PTLD).The gastrointestinal(GI)tract is commonly affected as it has an abundance of B and T *** To determine typical GI-manifestations,risk factors for developing PTLD,and *** Major databases were searched until November *** Non-case report studies that described GI manifestations of PTLD,risk factors for developing PTLD,and management of PTLD were *** articles written within the last 20 years were included in the *** articles found that patients with a history of SOT,regardless of transplanted organ,have a propensity to develop *** GI tract manifestations may be nonspecific;therefore,consideration of risk factors is crucial for identifying *** other lymphoma variants,PTLD is very aggressive making early diagnosis key to *** treatment is reduction of immunosuppression which is effective in more than 50%of cases;however,additional therapy including rituximab,chemotherapy,and surgery may also be required.

We present a general formulation based on punctual kriging and fuzzy concepts for image restoration in spatial domain. Gray-level images degraded with Gaussian white noise have been considered. Based on the pixel local neighborhood, fuzzy logic has been employed intelligently to avoid unnecessary estimation of a pixel. The intensity estimation of the selected pixels is then carried out by employing punctual kriging in conjunction with the method of Lagrange multipliers and estimates of local semi-variances. Application of such a hybrid technique performing both selection and intensity estimation of a pixel demonstrates substantial improvement in the image quality as compared to the adaptive Wiener filter and existing fuzzykriging approaches. It has been found that these filters achieve noise reduction without loss of structural detail information, as indicated by their higher structure similarity indices, peak signal to noise ratios and the new variogram based quality measures.

The effect of the severity of appendiceal inflammation on post-operative stay in children following appendicectomy has shown conflicting *** study was conducted to determine the association between the severity of appendiceal inflammation and post-operative stay amongst children undergoing open appendicectomy.A retrospective cohort study was conducted at a District General Hospital for two years.A total of 204 patients were included in the study with an age range between 3 and 16 *** were 54.9%while the rest were *** age was 12.5±3 *** association of the severity of appendiceal inflammation and post-operative stay was assessed by multivariable Cox Proportional hazards *** post-operative stay was 2.32 days(95%CI 2.14–2.51).Macroscopically perforated appendix,histological inflammation and post-operative complications were significantly associated with post-operative stay on univariable analysis(P<0.05).Whereas,the multivariable analysis showed that the post-operative stay was significantly prolonged only in case of either perforated appendix or post-operative complications while it remained unaffected by the histological inflammation.

In this study, we reported and validated a novel and sensitive reversed-phase liquid chromatographic method for the simultaneous determination of irbesartan, candesartan, gliquidone and pioglitazone. Separation was performed at 230 nm using a mobile phase consisting of methanol–water(90:10, v/v) with a flow rate of 1 mL/min. p H was adjusted to 3.5 with phosphoric acid. The concentration-response relationship was found linear over a concentration range of 5–25 μg/mL for all of the analytes tested. The limits of detection and quantification were 0.83 and 2.78 for irbesartan, 0.30 and 1.01 for candesartan, 1.11 and 3.93 for gliquidone, and 0.41 and 1.41 μg/mL for pioglitazone, respectively. Described method permitted the successful determination of these drugs in human serum. The developed method was simple, rapid, and it did not require extensive sample purification.

We study the Dirac and the Klein-Gordon oscillators in a noncommutative space. It is shown that the Klein-Gordon oscillator in a noncommutative space has a similar behaviour to the dynamics ofa particle in a commutative space and in a constant magnetic field. The Dirac oscillator in a noncommutative space has a similar equation to the equation of motion for a relativistic fermion in a commutative space and in a magnetic field, however a new exotic term appears, which implies that a charged fermion in a noncommutative space has an electric dipole moment.
