Abstract
Transforming growth factor (TGF)-β has a dual role in liver, providing cytostatic effects during liver damage and regeneration, as well as carcinogenic functions in malignant transformation and hepatocellular cancer. In cultured hepatocytes, TGF-β can trigger apoptosis and epithelial-mesenchymal transition (EMT). Caveolin-1 is associated with progression of hepatocellular cancer and has been linked to TGF-β signaling. This study aimed at elucidating whether Caveolin-1 regulates TGF-β mediated hepatocyte fate. Knockdown of Caveolin-1 strongly reduced TGF-β mediated AKT phosphorylation, thus sensitized primary murine hepatocytes for proapoptotic TGF-β signaling. Restoration of AKT activity in Caveolin-1 knockdown cells via expression of a constitutive active AKT mutant did not completely blunt the apoptotic response to TGF-β, indicating an additional mechanism how Caveolin-1 primes hepatocytes for resistance to TGF-β triggered apoptosis. On the molecular level, Caveolin-1 interfered with TGF-β initiated expression of the proapoptotic mediator BIM. Additionally, RNAi for Caveolin-1 reduced (and its overexpression increased) expression of antiapoptotic mediators BCL-2 and BCL-xl. Noteworthy, reduced Caveolin-1 protein levels had no effect on collagen 1α1, E- and N-cadherin expression upon TGF-β challenge and thus no effect on hepatocyte EMT. Hence, via affecting TGF-β mediated non-Smad AKT signaling and regulation of pro- and antiapoptotic factors, Caveolin-1 is a crucial hepatocyte fate determinant for TGF-β effects.

Abstract
Cytomegalovirus (CMV) is the most common viral infection following kidney transplant, has been recognized as a major factor for graft loss and increased incidence of acute rejection. Different studies have reported a variable incidence of CMV disease with the use of Mycophenolate mofetil (MMF). We retrospectively analyzed our renal transplant recipients to review the results of CMV disease and to compare CMV disease in patient on Azathioprine and MMF for this purpose we retrospectively reviewed 521 live related kidney transplant recipients at our institute. 74 (14.2 %) live related allograft recipients developed CMV disease after a median interval of 7.18 ± 4.35 months from transplantation. The mean age was 36.15 ± 10.7 years. 63 of the patients were male. Malaise, fever and diarrhea were among most common symptoms. 20 (27.02 %) of the 74 recipients developed transaminitis, 13 (17.2 %) developed CMV gastritis, 5 (9.13 %) recipients developed pneumonia, and 3 (4.05 %) patient developed colitis. 59 (80 %) patients had leucopenia and 41 (56.5 %) developed thrombocytopenia. Mean serum creatinine level was 1.5 ± 0.4 (0.9-2.4) mg/dl before the disease, 1.9 ± 0.6 (1.3-3.6) mg/dl at the time of the diagnosis, and 1.7 ± 0.06 (0.8-4.2) mg/dl at the end of the treatment. CMV disease developed in 9 (36 %) of recipients who received basiliximab as induction therapy and 13 (30.24 %) of recipients who received ATG (p > 0.05). The incidence of CMV disease was similar in cyclosporine based regimen (13.2 %) and Tacrolimus based regimen 27 (16.16 %) (p = 0.137) and was also similar in Azathioprine 41 (9.5 %) and MMF group 33 (14.3 %) (p = 0.163). There was no significant difference in severity of CMV disease in both groups, except a higher incidence of leucopenia in Azathioprine group (86 vs. 74 %, p < 0.05) as compared to MMF group. 51 (68.91 %) patient developed graft dysfunction during CMV disease. In conclusion we report a low incidence (14.2 %) and milder form of cytomegalovirus disease at our center. Use of universal cytomegalovirus prophylaxis was associated with a low incidence and milder form of the disease. Incidence of CMV disease was similar between Azathioprine and MMF groups.

Abstract
Dengue virus infection is an emerging global threat caused by Arbovirus, a virus from Flaviridiae family, which is transmitted by mosquitoes, Aedes aegypti and Aedes albopictus. Renal transplant recipients who live in the endemic zones of dengue infection or who travel to an endemic zone could be at risk of this infection. Despite multiple epidemics and a high case fatality rate in the Southeast Asian region, only a few cases of dengue infection in renal transplant recipients have been reported. Here, we report a case series of 8 dengue viral infection in renal transplant recipients. Of the 8 patients, 3 developed dengue hemorrhagic shock syndrome and died.

Abstract
Cardiovascular disease has become the leading cause of morbidity and mortality in renal transplant recipients, although its pathogenesis and treatment are poorly understood. Modifiable cardiovascular risk factors and graft dysfunction both play an important role in development of post transplant cardiovascular events. Prevalence of cardiovascular disease was studied in stable kidney transplant patients on cyclosporine based triple immunosuppression in relation to the various risk factors and post transplant cardiovascular events. Analysis of 562 post transplant patients with stable graft function for 6 months, the patients were evaluated for cardiovascular events in post transplant period. Pre and post transplant risk factors were analyzed using the COX proportional hazard model. 174 patients had undergone pre transplant coronary angiography, 15 of these patients underwent coronary revascularization (angioplasty in 12, CABG in 3). The prevalence of CAD was 7.2% in transplant recipients. Of 42 patients with CAD 31 (73.8%) had cardiovascular event in post transplant period. Age > or = 40 yrs, male sex, graft dysfunction, diabetes as primary renal disease, pre transplant cardiovascular event, chronic rejection showed significant correlation in univariate analysis and there was significant between age > or = 40 years (OR = 2.16 with 95% CI, 0.977-4.78) S creatinine > or = 1.4 mg % (OR = 2.40 with 95% CI, 1.20 - 4.82), diabetes as primary disease (OR with 95% CI 3.67, 3.2-14.82), PTDM (OR 3.67, 95% CI 1.45-9.40), pre-transplant cardiovascular disease (OR 4.14, 95% CI .38-13.15) with post transplant cardiovascular event on multivariate analysis. There was poor patient and graft survival among those who suffered post transplant cardiovascular event. The incidence of cardiovascular disease continues to be high after renal transplantation and modifiable risk factors should be identified to prevent occurrence of events in post transplant period.

Abstract
Antiphospholipid syndrome (APS) often presents as a multisystem disorder characterized by recurrent arterial and venous thrombosis and pregnancy loss. We present a 46-year-old female who was admitted with oliguric acute renal failure. APS was suspected due to prolongation of activated partial thromboplastin time and history of miscarriages. Investigations for secondary causes were normal. Renal biopsy findings revealed thrombotic microangiopathy. A complete recovery of renal function was attained with a combination of plasma exchange and pulse methylprednisolone followed by oral steroids and warfarin. The case is presented for its rarity and therapeutic implications.

Abstract
ABSTRACTThis paper is a survey of recent author's results obtained by the authors. It shows that many oxides can be obtained as thin epitaxial films in spite of their thermodynamic instability in bulk state at the film deposition conditions. This new synthetic approach, named epitaxial stabilization, is based on free energy gain due to structural coherence at the film/substrate interface. The epitaxial stabilization can be effectively used to enlarge the spectrum of new functional materials.

Abstract
The presence of both of the testes in one scrotal sac is one of the very rare presentations of testicular ectopia, which is known as transverse testicular ectopia (TTE) and is also known as crossed testicular ectopia. The presence of the uterus and fallopian tubes in a normally virilized male is termed as persistent Müllerian duct syndrome (PMDS). We report a case of an adult male who had a unique combination of both TTE and PMDS presenting as an incarcerated inguinal hernia.

Abstract
AIM Elucidate the incidence and causes of post transplant hypertension in our transplant population. METHODS All patients transplanted between June 1989 Dec 2002 who had a functioning graft of 6 months post transplant were studied. Hypertension was defined as Systolic BP > or = 140 mmHg/Diastolic BP > or = 90 mmHg/usage of antihypertensive medication. Donor and recepient characteristics were recorded and compared. 86.2% (485) were hypertensive in post renal transplant period. RESULTS Age > or = 40 years, male sex, graft dysfunction, use of calcineurin inhibitors, high doses of steroids, chronic rejection were statistically significant correlate of post RTHT in univariate analysis. On multivariate analysis, age > or = 40 yrs (RR 2.06, 95% CI, 1.20-3.54), use of cyclosporine (RR 2.70, 95% CI, 1.54-4.75), usage of high doses of steroids (RR 2.56, 95% CI, 1.31-4.98) only were associated with post transplant hypertension. The patient and graft survival was inferior in patients with post transplant hypertension. The systolic BP at 12 months, diastolic BP at 6 months and 12 months post transplant, had significant detrimental effect on renal allografts survival. CONCLUSION Diagnosis, identification of risk factors and aggressive treatment of post transplant HT and of the various modifiable risk factors is important for improving renal allograft and patient survival.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2009; 16:1112-1118.

Abstract
The genotoxic potential of anti-inflammatory/anti-arthritic and anticancer plant based drug molecule Boswelic acids (BA) was studied by in vivo system. Systematic literature survey revealed that studies on the genotoxicity of BA are not available. Although reports on genotoxicity of Boswellia serrata dry extract and modified 3-O-acetyl-11-keto-beta-boswelic acid are available and these studies were conducted in in vitro systems. The earlier general toxicity study of BA has been conducted by us, revealed it to be non toxic. The genotoxicity was carried out in Wistar rats using different cytogenetic assay system-abnormalities viz. chromosomal aberrations; sperm morphology, micronuclei and comet assays. Six groups of animals, each comprised of five rats, were taken for each study. Group1-4 received BA at 125, 250, 500 and 1000 mg/kg p.o., respectively prepared as 2% gum acacia suspension, fifth group received a positive control cyclophosphamide (CP) 40 mg/kg p.o. or metronedazole (MTZ) 130 mg/kg p.o. or mercuric chloride (HgCl(2)) 0.864 mg/kg p.o. (as per the experiment requirement) whereas the sixth group kept as vehicle control. The results on the bases of the data obtained revealed that BA is quite safe as it did not show any genotoxicity at any dose level up to 1000 mg/kg. The positive controls used in different experiments showed highly significant abnormal cytogenetic changes in comparison to the control group.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Roots of Asparagus racemosus Willd (Shatavari in vernacular) are widely used in Ayurveda as Rasayana for immunostimulation, galactogogue as also in treatment of conditions like ulcers and cancer. Various studies have indicated immunomodulatory properties of Shatavari root extracts and formulations. AIM OF THE STUDY To study the effect of standardized Asparagus racemosus root aqueous extract (ARE) on systemic Th1/Th2 immunity of SRBC sensitized animals. MATERIALS AND METHODS We used HPTLC to quantify steroidal saponins (Shatavarin IV, Immunoside) and flow cytometry to study effects of ARE on Th1/Th2 immunity. SRBC specific antibody titres and DTH responses were also monitored as markers of Th2 and Th1 responses, respectively. We also studied lymphocyte proliferation. Cyclosporin, cyclophosphamide and levamisole were used as controls. RESULTS Treatment with ARE (100mg/(kg b.w.p.o.)) resulted in significant increase of CD3(+) and CD4/CD8(+) percentages suggesting its effect on T cell activation. ARE treated animals showed significant up-regulation of Th1 (IL-2, IFN-g) and Th2 (IL-4) cytokines suggesting its mixed Th1/Th2 adjuvant activity. Consistent to this, ARE also showed higher antibody titres and DTH responses. ARE, in combination with LPS, Con A or SRBC, produced a significant proliferation suggesting effect on activated lymphocytes. CONCLUSION The study suggests mixed Th1/Th2 activity of ARE supports its immunoadjuvant potential.

Abstract
Macroscopic resonant tunneling between the two lowest lying states of a bistable rf SQUID is used to characterize noise in a flux qubit. Measurements of the incoherent decay rate as a function of flux bias revealed a Gaussian-shaped profile that is not peaked at the resonance point but is shifted to a bias at which the initial well is higher than the target well. The rms amplitude of the noise, which is proportional to the dephasing rate 1/tauphi, was observed to be weakly dependent on temperature below 70 mK. Analysis of these results indicates that the dominant source of low energy flux noise in this device is a quantum mechanical environment in thermal equilibrium.

Abstract
BACKGROUND This study aimed to examine hospital volume in New York state as a predictor of complications over 13 years. METHODS Data from the New York state Statewide Planning and Research Cooperative Systems database were analyzed by diagnosis-related group, patient demographics, and outcomes. The institution data were analyzed on the basis of volume and logistic regression using chi-square analysis for predicting morbidity and mortality. RESULTS From 1991 to 2003, 24,534 patients underwent bariatric surgery at 79 institutions. Case volume increased 36-fold in high-volume centers (HVCs), whereas the overall number of institutions doubled. The average mortality rate was 1.1% in low-volume centers (LVCs), 0.4% in medium-volume centers (MVCs), and 0.2% in HVCs. Whereas 12.4% of the LVC patients had postoperative anastomotic complications (PACs), only 9.7% had PACs in MVCs and only 7.3% had PACs in HVCs (p < 0.05). Furthermore, only 0.7% of the patients required postoperative reintubation (PRI) after surgery at HVCs, as compared with 1.5% at MVCs and 1.8% at LVCs (p < 0.05). Finally, 1.8% of the patients required blood transfusion of packed red blood cells at HVCs, whereas 2.4% required transfusion at MVCs and LVCs. CONCLUSIONS Experience correlates with fewer postoperative complications, including death, in bariatric centers in New York state.
