AIMS: To evaluate the risk of cardiac failure (CF) of 15 anticancer protein kinase inhibitors (PKIs) through a case/non-case analysis and to identify which PK(s) and pathways are involved in PKI-induced CF. METHODS: To evaluate the risk of CF, adjusted reporting odds ratios (aRORs) were calculated for the 15 anticancer PKIs in the WHO safety report database (VigiBase®). We realised a literature review to identify 21 PK possibly involved in CF caused by PKIs. Pearson's correlation coefficients (r) between aROR and affinity data of the 15 PKIs for the 21 PKs were calculated to identify the cellular target most likely involved in PKI-induced CF...

BACKGROUND: Both chronic alcohol consumption and alcohol withdrawal lead to neural tissue damage which partly recovers during abstinence. This study investigated withdrawal-associated changes in glutamatergic compounds, markers of neuronal integrity, and gray matter volumes during acute alcohol withdrawal in the hippocampus, a key region in development and maintenance of alcohol dependence in humans and rats. METHODS: Alcohol-dependent patients (N = 39) underwent magnetic resonance imaging (MRI) and MR spectroscopy (MRS) measurements within 24 hours after the last drink and after 2 weeks of abstinence...

Among a number of clinical factors, bacterial infection is one of the most common causes of acute lung injury (ALI), a serious complication that carries a high risk of mortality (~40%). During the process of ALI, intense local and systemic inflammation is elicited, which exacerbates the injury. Neutrophil infiltration into airspace is observed in early stage of ALI, and is required for the full development of ALI through an array of mechanisms, including the release of granule contents and the production of pro‑inflammatory cytokines, due to the overactivation of complement and cytokines...

Williams-Beuren syndrome (WBS, no. OMIM 194050) is a rare multisystem genetic disorder caused by a microdeletion on chromosome 7q11.23 and characterized by cardiovascular malformations, mental retardation, and a specific facial dysmorphism. Recently, we reported that a series of non‑Hodgkin's lymphoma occurs in children with WBS and thus hypothesized that a predisposition to cancer may be associated with this genetic disorder. The aim of the present study was to ascertain the role played by three genes hemizygously deleted in WBS (RFC2, GTF2I and BAZ1B) in DNA damage response pathways...
