A prominent feature of many human cancers is oncogene-driven activation of the DNA damage response (DDR) during early tumorigenesis. It has been shown previously that noninvasive imaging of the phosphorylated histone H2A variant H2AX, γH2AX, a DNA damage signaling protein, is possible using (111)In-labeled anti-γH2AX antibody conjugated to the cell-penetrating peptide transactivator of transcription (TAT). The purpose of this study was to investigate whether (111)In-anti-γH2AX-TAT detects the DDR during mammary oncogenesis in BALB-neuT mice.', 'Mammary fat pads from BALB-neuT and wild-type mice (age, 40-106 d) were immunostained for γH2AX. (111)In-anti-γH2AX-TAT or a control probe was administered intravenously to BALB-neuT mice. SPECT was performed weekly and compared with tumor detection using palpation and dynamic contrast-enhanced MR imaging.', 'γH2AX expression was elevated in hyperplastic lesions in the mammary fat pads of BALB-neuT mice aged 76-106 d, compared with normal fat pads from younger mice and carcinomas from older mice (13.5 ± 1.2 γH2AX foci/cell vs. 5.2 ± 1.5 [P < 0.05] and 3.4 ± 1.1 [P < 0.001], respectively). Serial SPECT imaging revealed a 2.5-fold increase in (111)In-anti-γH2AX-TAT accumulation in the mammary fat pads of mice aged 76-106 d, compared with control probe (P = 0.01). The median time to detection of neoplastic lesions by (111)In-anti-γH2AX-TAT (defined as >5% injected dose per gram of tissue) was 96 d, compared with 120 and 131 d for dynamic contrast-enhanced MR imaging and palpation, respectively (P < 0.001).

It has been suggested that early localization of both necrosis and extrapancreatic fluid collections by contrast-enhanced computed tomography (CT) can predict the outcome in severe acute pancreatitis. These two assumptions were evaluated.', 'This study comprises 228 patients with a first attack of acute pancreatitis admitted to our clinic from 1987 to 1995 and for whom the prognostic value of a contrast-enhanced CT obtained within 72 h of admission was prospectively evaluated. These CTs were retrospectively re-evaluated for the localization of pancreatic necrosis and extrapancreatic fluid collections. The indication for dialysis and artificial ventilation, the development of pancreatic pseudocysts, the necessity for surgery (necrosectomy), and mortality were used as clinical parameters.', 'There was a significant correlation between the presence of pancreatic necrosis and extrapancreatic fluid collections versus the clinical parameters. The localization of pancreatic necrosis was of no importance for the outcome of the disease, whereas the increasing amount of extrapancreatic fluid collections paralleled the severity of acute pancreatitis.

Improving quality of life (QoL) is an important objective in the treatment of schizophrenia. The aim of the current study was to examine to what extent resilience, self-esteem, hopelessness, and psychopathology are correlated with QoL.', 'We recruited 52 out-patients diagnosed with schizophrenia according to DSM-IV criteria and 77 healthy control subjects from the general community. In patients, psychopathology was quantified by the Positive and Negative Syndrome Scale. The following scales were used in both patients and control subjects: the Berliner Lebensqualitätsprofil, the Resilience Scale, the Rosenberg Self-Esteem Scale, and the Beck Hopelessness Scale to assess QoL, resilience, self-esteem, and hopelessness respectively.', 'Patients with schizophrenia presented with significantly less QoL, resilience, self-esteem, and hope compared to healthy control subjects. In patients, QoL correlated moderately with resilience, self-esteem, and hopelessness and weakly with symptoms. With respect to the latter, particularly depression and positive symptoms were negatively correlated with QoL.
