Iron deficiency anemia (IDA) is a health problem in Indonesia. Prevention and treatment of IDA carried out by giving fortified foods oral iron therapy. Both can use ferrous fumarate which made with reacting bivalent disodium fumarate. Bivalent be obtained from sand This study aims to synthesize Indonesian sand, Malang, Sukabumi, Cianjur area, determine its absorption through vivo body weight ga...

It cannot be denied that the change from analog to digital technology had an enormous effect on how we communicate in daily life. For somebody who grew up within the last 20 years it is difficult to imagine a world without cell phones, email, or online communities. The digital revolution has not only changed our daily life, it also had a significant impact on the way we share information in med...

mono-specific antisera against vibrio cholera ogawa nih-43 and vibrio cholera inaba 35-a3 were prepared from rabbit hyperimmune sera by absorbing against a heterologous strain. using ammonium sulphate precipitation procedure, gamma globulins were purified and concentrated. to visualize antigen-antibody reaction, gamma globulins were conjugated to staphylococcus aureus cowan-l (nctc: 8325) in th...

Multiple mechanisms of epigenetic control that include DNA methylation, histone modification, noncoding RNAs, and mitotic gene bookmarking play pivotal roles in stringent gene regulation during lineage commitment and maintenance. Experimental evidence indicates that bivalent chromatin domains, i.e., genome regions that are marked by both H3K4me3 (activating) and H3K27me3 (repressive) histone mo...

A model to quantitate the principal aspects of multivalent binding was developed. It describes the random distribution of an immobilized component (the ligand) taking into account local densities. The binding of a bivalent molecule (the analyte) to the ligand is described as occurring in two steps, the second of which is driven by the local concentration of neighboring ligands. The model was us...

The most highly conserved noncoding elements (HCNEs) in mammalian genomes cluster within regions enriched for genes encoding developmentally important transcription factors (TFs). This suggests that HCNE-rich regions may contain key regulatory controls involved in development. We explored this by examining histone methylation in mouse embryonic stem (ES) cells across 56 large HCNE-rich loci. We...

We used the interaction between human serum albumin (HSA) and a high-affinity antibody to evaluate binding affinity measurements by the bench-top liSPR system (capitalis technology GmbH). HSA was immobilized directly onto a carboxylated sensor layer, and the mechanism of interaction between the antibody and HSA was investigated. The bivalence and heterogeneity of the antibody caused a complex b...

1. The bilirubin UDP-glucuronyltransferase assay described by Van Roy & Heirwegh (1968) has been improved. 2. Extraction of final azo-derivatives is rendered more simple and efficient by thorough emulsification and by cooling. 3. Pretreatment of homogenates and cell fractions with digitonin increases the sensitivity of the assays and gives less variable results than those with untreated prepara...

this study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. the results indicate that four different ranges of s...
