Neuroendocrine (NE) differentiation in prostate cancer (PCa), promoted by NE cell secreted products, appears to be associated with tumor progression, poor prognosis, and hormone-refractory disease. We recently reported secretagogin, a hexa-EF-hand Ca(2+) binding protein, as a novel NE marker in carcinoid tumors of the lung and the gastrointestinal tract. The present study analyzes the expression of secretagogin in normal and malign prostate tissue.', 'We analyzed immunoreactivity for secretagogin, chromogranin A (CgA), neuron specific enolase (NSE), and synaptophysin (SYN) in consecutive sections from 87 formalin-fixed paraffin-embedded (FFPE) benign hyperplastic (n = 10) and prostate adenocarcinoma (n = 77) specimens. The intracellular distribution of secretagogin, CgA, and NSE was examined by confocal fluorescent microscopy, and we characterized secretagogin in eight samples by Western blotting.', 'Secretagogin is cytoplasmic and nuclear expressed in NE and NE differentiated cells, and to a lesser extent in epithelial cells, in the benign prostate and prostate adenocarcinoma cells. Secretagogin stained 82% (46/56) of benign and 71% (48/68) of prostate adenocarcinomas and co-localized with the NE markers CgA and NSE. The expression of secretagogin is significantly correlated to CgA (P < 0.001) and NSE (P < 0.048) in prostate adenocarcinoma and to CgA in normal epithelium (P < 0.028).

Is secretagogin a new neuroendocrine marker in the human prostate?

An intense systemic inflammatory response is observed following reperfusion after cardiac arrest. Heparin-binding protein (HBP) is a granule protein released by neutrophils that intervenes in endothelial permeability regulation. In the present study, we investigated plasma levels of HBP in a large population of patients resuscitated from out-of-hospital cardiac arrest. We hypothesized that high circulating levels of HBP are associated with severity of post-cardiac arrest syndrome and poor outcome.', 'Plasma was obtained from 278 patients enrolled in a prospective multicenter observational study in 21 intensive care units (ICU) in Finland. HBP was assayed at ICU admission and 48\xa0h later. Multiple organ dysfunction syndrome (MODS) was defined as the 24\xa0h Sequential Organ Failure Assessment (SOFA) score\u2009≥\u200912. ICU death and 12-month Cerebral Performance Category (CPC) were evaluated. Multiple linear and logistic regression tests and receiver operating characteristic curves with area under the curve (AUC) were performed.', 'Eighty-two percent of patients (229 of 278) survived to ICU discharge and 48\xa0% (133 of 276) to 1\xa0year with a favorable neurological outcome (CPC 1 or 2). At ICU admission, median plasma levels of HBP were markedly elevated, 15.4 [9.6-31.3] ng/mL, and persisted high 48\xa0h later, 14.8 [9.8-31.1] ng/mL. Admission levels of HBP were higher in patients who had higher 24\xa0h SOFA and cardiovascular SOFA score (p\u2009<\u20090.0001) and in those who developed MODS compared to those who did not (29.3 [13.7-60.1] ng/mL vs. 13.6 [9.1-26.2] ng/mL, p\u2009<\u20090.0001; AUC\u2009=\u20090.70\u2009±\u20090.04, p\u2009=\u20090.0001). Admission levels of HBP were also higher in patients who died in ICU (31.0 [17.7-78.2] ng/mL) compared to those who survived (13.5 [9.1-25.5] ng/mL, p\u2009<\u20090.0001) and in those with an unfavorable 12-month neurological outcome compared to those with a favorable one (18.9 [11.3-44.3] ng/mL vs. 12.8 [8.6-30.4] ng/mL, p\u2009<\u20090.0001). Admission levels of HBP predicted early ICU death with an AUC of 0.74\u2009±\u20090.04 (p\u2009<\u20090.0001) and were independently associated with ICU death (OR [95 %CI] 1.607 [1.076-2.399], p\u2009=\u20090.020), but not with unfavorable 12-month neurological outcome (OR [95 %CI] 1.154 [0.834-1.596], p\u2009=\u20090.387).

The effect of type 2 diabetes mellitus (adult-onset non-insulin-dependent), which is the most common form of diabetes in humans, on osseointegration capacity has not been addressed in an appropriate animal model. This study histologically and histomorphometrically examines bone healing around titanium implants in the type 2 diabetes rat model.', 'Titanium implants with a chamber were placed into the femurs of normal male rats and genetically modified male rats with a close symptomatic resemblance to human type 2 diabetes, as characterized by late-onset hyperglycemia and obesity. Cross-sectional histology for the tissue grown into the implant chamber was examined.', 'Bone volume around implants was consistently (from weeks 4 to 8 postimplantation) smaller for the diabetes group than for the control group in the cortical area, while the bone volume in the marrow area was not affected by the diabetes. Bone-implant contact percentage was considerably lower for the diabetes group in both the cortical and marrow areas, with the week 4 bone-implant contact in the cortical area being 12% for the diabetes group and 61% for the control group. A 2-fold difference remained at week 8. Bone morphogenesis in the diabetic rats was characterized by fragmented bone tissues and extensive soft tissue intervention.
