Farmer knowledge exchanges about the experiment have been investigated using a mix of quantitative and qualitative methods. Network surveys identified who the farmers contacted for knowledge before the study began and who they had talked to about the experiment by 18 months later. Open-ended interviews collected farmer statements about their most valuable contacts and these statements have been thematically analysed. The network analysis shows that farmers talked about the experiment with 192 people, most of whom were fellow farmers. Farmers with densely tied and occupationally homogeneous contacts grew their networks more than did farmers with contacts that are loosely tied and

diverse. Thematic analysis reveals three general principles: farmers value knowledge delivered by persons rather than roles, privilege farming experience, and develop knowledge with Cytoskeletal Signaling inhibitor empiricist rather than rationalist techniques. Taken together, these findings suggest that farmers deliberate about science in intensive and durable networks

that have significant implications for theorizing agricultural innovation. The paper thus concludes by considering the findings’ significance for current efforts to rethink agricultural extension.”
“Struma ovarii is an uncommon ovarian teratoma comprised predominantly of mature thyroid tissue. The combination of pseudo-Meigs’ syndrome, and elevation of CA 125 to the struma ovarii is a rare condition that can mimic ovarian malignancy. We reported a case of ZD1839 benign struma ovarii, presenting with the clinical features of advanced ovarian carcinoma: complex pelvic mass, gross ascites, bilateral pleural effusion and markedly elevated serum CA 125 levels. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Ascites and pleural effusion were not evident and the CA 125 levels returned to normal following surgical excision. A systematic review of reported cases of coexistent benign struma ovarii, pseudo-Meigs’ syndrome and elevated serum CA 125 was performed. Struma ovarii accompanied by pseudo-Meigs’ syndrome and elevated serum CA 125 should be considered in the differential diagnosis of ovarian epithelial cancer.”
“Obestatin,

encoded by the same gene as ghrelin, was first described as a physiological opponent of ghrelin. We investigated fasting plasma ghrelin and obestatin levels AZD7762 and ratio of ghrelin to obestatin in humans with untreated mild-to-moderate hypertension and humans with normal blood pressure. We found that the plasma concentration of ghrelin and the ratio of ghrelin to obestatin were significantly lower in hypertension group compared with control group (236.3 +/- 12.3 pg/ml vs 381.4 +/- 25.6 pg/ml, P<0.01: 0.89 +/- 0.06 vs 1.2 +/- 0.06, P<0.01). The plasma concentration of obestatin was lower in hypertension group compared with control group, but the difference between the two groups was not significant (276.2 +/- 15.1 pg/ml vs 325.4 +/- 25.8 pg/ml, P>0.05).
