Japanese encephalitis virus (JEV) is a fatal disease in Asia. Pigs are considered to be the effective amplifying host for JEV in the peridomestic environment. Bali Island and Java Island in Indonesia provide a model to assess the effect of pigs on JEV transmission, since the pig density is nearly 100-fold higher in Bali than Java, while the geographic and(More)
Dengue fever and dengue hemorrhagic fever are important diseases worldwide. Although antibody-dependent enhancement of infection has been proposed as a mechanism for increased disease severity, enhancing antibodies in endemic people have not been thoroughly investigated. Recently, we established a serological assay system to measure the balance of enhancing(More)
Indonesia has annually experienced approximately 100,000 reported cases of dengue fever (DF) and dengue hemorrhagic fever (DHF) in recent years. However, epidemiological surveys of dengue viruses (DENVs) have been limited in this country. In Surabaya, the second largest city, a single report indicated that dengue virus type 2 (DENV2) was the predominant(More)
Dengue hemorrhagic fever (DHF) is a severe form of dengue fever (DF). Recent in vitro studies indicate that complement reduces the infection-enhancing activity of dengue antibodies, suggesting its in vivo role in controlling viremia levels and disease severity. In this study, the complement hemolytic activity (CH50) and levels of complement components and(More)
Background: Human umbilical cord mesenchymal stem cell is a promising source of allogenous MSC with great chondrogenic differentiation capacity. Meanwhile, platelet rich fibrin (PRF) is a natural fibrin matrix, rich in growth factors, forming a smooth and flexible fibrin network, supporting cytokines and cell migration, thus can be used as a scaffold that(More)
AIM to speed up transdifferentiation of bone marrow-derived stem cells into cardiomyocyte in vitro by inducing dedifferentiation of bone marrow-derived mesenchymal stem cell, before induction by 5-aza-2'-deoxycytidine into cardiomyocyte. METHODS two-three months old 2.5 kg weight adult male New Zealanad Rabbits were anesthezied with ether, thigh bones(More)
