Effects of natto extract on endothelial injury in a rat model

Vascular endothelial damage has been found to be associated with thrombus formation, which is considered to be a risk factor for cardiovascular disease. A diet of natto leads to a low prevalence of cardiovascular disease. The aim of the present study was to investigate the effects of natto extract on vascular endothelia damage with exposure to laser irradiation. Endothelial damage both in vitro and in vivo was induced by irradiation of rose bengal using a DPSS green laser. Cell viability was determined by MTS assay, and the intimal thickening was verified by a histological approach. The antioxidant content of natto extract was determined for the free radical scavenging activity. Endothelial cells were injured in the presence of rose bengal irradiated in a dose-dependent manner. Natto extract exhibits high levels of antioxidant activity compared with purified natto kinase. Apoptosis of laser-injured endothelial cells was significantly reduced in the presence of natto extract. Both the natto extract and natto kinase suppressed intimal thickening in rats with endothelial injury. The present findings suggest that natto extract suppresses vessel thickening as a synergic effect attributed to its antioxidant and anti-apoptosis properties

Hospital treatment, mortality and healthcare costs in relation to socioeconomic status among people with bipolar affective disorder

BACKGROUND: Evidence regarding the relationships between the socioeconomic status and long-term outcomes of individuals with bipolar affective disorder (BPD) is lacking. AIMS: We aimed to estimate the effects of baseline socioeconomic status on longitudinal outcomes. METHOD: A national cohort of adult participants with newly diagnosed BPD was identified in 2008. The effects of personal and household socioeconomic status were explored on outcomes of hospital treatment, mortality and healthcare costs, over a 3-year follow-up period (2008–2011). RESULTS: A total of 7987 participants were recruited. The relative risks of hospital treatment and mortality were found elevated for the ones from low-income households who also had higher healthcare costs. Low premium levels did not correlate with future healthcare costs. CONCLUSIONS: Socioeconomic deprivation is associated with poorer outcome and higher healthcare costs in BPD patients. Special care should be given to those with lower socioeconomic status to improve outcomes with potential benefits of cost savings in the following years. DECLARATION OF INTEREST: None.

Laparoscopic management of a giant adrenal cyst

AbstractAdrenal cysts, a rare entity, are usually nonfunctional and asymptomatic. Here, we report a 32-year-old woman who presented with mild breathlessness and vague abdominal fullness and discomfort that had lasted 6 months. Chest radiography showed elevation of the left side of the diaphragm. Abdominal sonography showed an anechoic lesion of >15cm, without a septum, that was situated over the left abdominal area. Abdominal computed tomography (CT) showed a 20cm suprarenal cyst located between the pancreas, spleen, and left kidney, causing anterior displacement of the pancreas and inferior displacement of the left kidney. Magnetic resonance imaging confirmed the CT and sonographic findings, and revealed that the cystic mass was originating from the left adrenal gland. Fluid analysis of the cystic lesion showed no evidence of infection or malignancy. A laparoscopic adrenalectomy was performed. Histopathologically, the adrenal tissue showed no evidence of adenoma or malignancy, and the cystic component showed a flattened endothelial lining with fibrotic tissue, consistent with an endothelial cyst. The postoperative course was uneventful and the patient had no evidence of recurrence during a 6-year follow-up. We discuss the diagnosis and management of adrenal cysts

Separation, characterization and leaching behaviors of heavy metals in contaminated river sediments

In this research, the sequential extraction test was conducted to understand the characteristic of heavy metals in the sediment. Subsequently, the pH-dependent leaching test, percolation test were subjected to explore the possible leaching of heavy metals and stabilizing mechanism. Finally, based on the resuts of pH dependent test,the acid/chemical washing were applied to predict long-term, leaching characteristics. The results from the sediment characteristic analyses showed that the concentrations of heavy metals (such as Cu, Pb, Zn, Ni, and Cr) in river sediments exceeded the upper limit of Sediment Quality Standard of Taiwan, implying further decontamination works should be addressed. Results from the chemical washing (extraction) showed that the heavy metal removal efficiency was good when washed with 2N HCl for 120 minutes; the order of removal efficiency was Ni 90% > Zn 87% > Pb 85% > Cu 83% > Cr 70%. For chelation extraction, the suitable operating condition was achieved with 0.5M Citric Acid after 120 minutes contact; the order of heavy metal ion capturing efficiency was Zn 61% > Ni 54% > Pb 40% > Cu 36% > Cr 24%. Comparing the heavy metal bonding types before and after chemical washing (extraction) showed that some metal ions exist in residual forms in the sediments (Ni, Zn, Cu); however, after the washing process, the heavy metal ions became more exchangeable forms with higher bioavailability.
