Previous studies on the effect of gonadotropin-releasing hormone (LHRH) agonist on prolactin (PRL) secretion from normal and tumorous pituitary cells have not been conclusive as to the mechanism of action of these agonists. In this study the short-term administration of a LHRH agonist did not affect circulating PRL lev... |
In this paper it is argued that Barad's Agential Realism, an approach to quantum mechanics originating in the philosophy of Niels Bohr, can be the basis of a 'theory of everything' consistent with a proposal of Wheeler that observer-participancy is the foundation of everything. On the one hand, agential realism can be ... |

PURPOSE |
The aim of the present study is to evaluate the concordance between preoperative endometrial sampling histopathology performed by conventional dilatation and curettage (D&C) and final histopathological diagnosis after total hysterectomy concerning tumor grade and subtype in patients with endometrial cancer (EC). |
METHODS |
In this comparative retrospective study, 203 women with endometrial cancer were included who underwent at first dilatation and curettage and then total hysterectomy. The preoperative histopathological report obtained by dilatation and curettage was compared with the final histopathology after total hysterectomy to asse... |
RESULTS |
Comparison of preoperative with postoperative histopathological results showed an overall 5.9% and 10.9% discordance regarding endometrial cancer histological subtype and grade, respectively. Six (4.9%) of the patients with preoperative grade 1 were grade 2 and 1 (0.8%) was found to be grade 3. Three (8.3%) of the pati... |
CONCLUSION |
Patients should be informed and consent for the potential discrepancy between the pre and postoperative histopathological features of malignancy. This discrepancy may result in either under or overtreatment. Thus, it should be accounted for when counseling for a major operation.Physiological rationale of aggressive beh... |
The physiological rationale of aggressive behavior is discussed. The potential importance of homeostatic reaction in brain blood perfusion is described.

BACKGROUND |
Obesity is a rapidly progressing pandemic and a central feature of the metabolic syndrome. There is no solid evidence on the recent trends of obesity in Iran. In this study we present the secular trends of overweight and obesity among Iranian adults (25-64 years old) within an 8-year period (1999-2007). |
METHODS |
The analyses were performed on the datasets of three cross-sectional national surveys: The National Health Survey-1999 (n = 21,576), National Surveys of Risk Factors for Non-Communicable Diseases (SuRFNCD)-2005 (n = 70,945), and SuRFNCD-2007 (n = 4,186). |
