Background and Aim: Iran managed to eradicate the wild poliovirus in 2000. However, a large number of AFP cases are still detected each year because of close surveillance: there were 450 reported AFP cases in 1382. The expected number of cases for the year 1382 in the province of West Azarbayjan (with an under-15 population of 1100000) was 11, while the observed number was more than 6 times gre...
Background and Objectives: : According to the global strategy for polio eradication, targeted surveillance of the disease is one of the main tasks of the health system. The purpose of this study was to review the status and surveillance of poliomyelitis/acute flaccid paralysis (AFP) in Iran. Methods: The present study was a review on the processes, structures and achievements of the poliomy...
A purified preparation of antifungal protein (AFP) from Aspergillus giganteus exhibited potent antifungal activity against the phytopathogenic fungi Magnaporthe grisea and Fusarium moniliforme, as well as the oomycete pathogen Phytophthora infestans. Under conditions of total inhibition of fungal growth, no toxicity of AFP toward rice protoplasts was observed. Additionally, application of AFP o...
BACKGROUND The infection of Hepatitis B virus (HBV) is closely associated with the development of hepatocellular carcinoma(HCC), HBV-X protein(HBx) is able to induce expression of alpha-fetoprotein(AFP) in normal liver cells, and AFP harbors a function to promote malignant transformation of normal liver cells, but the role AFP playing in malignant behaviors of HCC cells is still unclear. METH...
Background The American Association for the Study of Liver Diseases (AASLD) recommends semi-annual hepatocellular carcinoma (HCC) screening using ultrasound (US) in persons with chronic hepatitis B (CHB) virus infection at high risk for HCC such as Asian males aged ≥40 years and Asian females aged ≥50 years. Objective To analyse the cost-effectiveness of 2 HCC screening methods in the Alaska Na...
OBJECTIVE To describe the association between pregnancy associated plasma protein A (PAPP-A), alpha-fetoprotein (AFP) and adverse perinatal outcome. METHODS We conducted a multicenter prospective cohort study of 8,483 women attending for prenatal care in southern Scotland between 1998 and 2000. The risk of delivering a small for gestational age infant, delivering preterm, and stillbirth were ...
A novel strategy is presented for sensitive detection of alfa-fetoprotein (AFP), using a horseradish peroxidase (HRP)-functionalized Envision antibody complex (EVC) as the label. The Envision-AFP signal antibody copolymer (EVC-AFP Ab2) was composed of a dextran amine skeleton anchoring more than 100 molecules of HRP and 15 molecules of secondary antibody, and acted as a signal tag in the immuno...
OBJECTIVE To explore the expression and significance of tumor specific growth factor (TSGF), carcinoembryonic antigen (CEA) and alpha fetoprotein (AFP) in cancer tissue and serum of patients with colon cancer. MATERIALS AND METHODS Radical surgery for colon cancer was performed on 43 patients with laparoscope under conditions of general anesthesia. The Elisa method was used to detect the leve...
Mouse amniotic fluid was shown to contain a noncytotoxic inhibitor of primary gammaM and secondary gammaM, gammaG subclass splenic plaque forming cells in vitro to SRBC. The suppressive effect was not abolished by exhaustive dialysis or by absorption of mouse amniotic fluid (MAF) with SRBC. Polyacrylamide gel analysis showed that dialyzed MAF was composed of three major protein components, tran...
