Enantioselective Total Syntheses of the Proposed Structures of Prevezol B and Evaluation of Anti-Cancer Activity
The first enantioselective total syntheses of the proposed structures of the natural product prevezol B are reported. The reported syntheses complement the previously-reported syntheses of the proposed structures of prevezol C, a stereoisomer of prevezol B. It was previously shown that the structure of the naturally occurring prevezol C had been incorrectly assigned. This work has led us to conclude that the proposed structures of prevezol B are also incorrect and major revision of both of the structures of the prevezols B and C is required. Cytotoxicity studies on the human cervical cancer cell line HeLa revealed that the synthesized prevezol B and C compounds were not active even at the highest concentration used (100 μM). However, one of the synthetic precursors was shown to have modest potency against HeLa cells (IC50 = 23.5 ± 1.8 μM)

Renal hyperfiltration and outcome in HIV-infected subjects.
Evidence from the general population suggests that renal hyperfiltration portends poor prognosis in the general population. No data in HIV-infected subjects is available. Hence, we investigated prevalence, associations with traditional and HIV-related risk factors as well as the prognostic significance of renal hyperfiltration in a large cohort of HIV-infected subjects
Incidence and prevalence of cancer in kidney transplantation waiting list patients: an italian experience.
Introduction: Evaluation of kidney transplant candidates is based on strict exclusion of major pathologies, such as neoplastic disease. The aim of this study is to evaluate epidemiological and clinical impact of tumor disease in an Italian renal transplant waiting list and to propose a screening schedule for neoplastic detection.\u2029Materials and methods: We retrospectively observed data of patients enrolled on the Emilia-Romagna kidney transplant waiting list between 1st August 2008 and 31st December 2010, evaluating the different causes of getting out from the list, the histologic type and incidence of cancer and the correlation between cancer onset and clinical features. The ratio of observed to expected cancer numbers (standardized incidence ratio, SIR), was estimated. \u2029Results: We observed 2345 patients; 1297 got out from the waiting list; 57 of them (4,4%) got out because the onset of tumor. The overall incidence rate of cancer was 1354.8 (x 100000 person-year) (1045.9 person-year in patients awaiting for first transplant(FT), 1851.5 person-year in patients awaiting for second transplant(ST)). The overall prevalence of cancer was 2,43% (2.2% in FT, 3.4% in ST) with a SIR of 1.8; In our population the prevalence of cancers related to ESKD was 52.6% with a SIR of 15.8.\u2029Conclusion: Kidney transplant waiting list patients present a higher incidence and prevalence of cancer compared to general population; it could be important to evaluate them for ESKD related malignancies because of their high incidence
Kidney transplantation in genetic (Factor H deficient) haemolitic-uremic syndrome (HUS)
Interpretation of kidney graft outcome in HUS
is frequently hindered by heterogeneity of case-mix; epidemic, more than
idiopathic, and some mutations in complement system, such as membrane
cofactor protein (MCP), carry a favourable prognosis, when compared with
the more severe forms of factor H and I deficiency. Relapse of basic disease
is common, particularly when calcineurin inhibitors (CNI) are used; rescue
by means of plasma therapy is seldom and temporarily successful. Here we
report a case of transplantation in Factor H deficient HUS
