Earthworms are a major part of the total biomass of soil fauna and play a vital role in soil maintenance. They process large amounts of plant and soil material and can accumulate many pollutants that may be present in the soil. Earthworms have been explored as bioaccumulators for many heavy metal species such as Pb, Cu and Zn but limited information is available for mercury uptake and bioaccumu...

The present study investigated the acute toxic effects of a metal-loaded Bauxsol reagent (MLBR), containing more than 6,450 mg kg(-1) of bound metal, on the earthworm Eisenia fetida. Bauxsol is manufactured by Virotec Global Solutions of Gold Coast, Queensland, Australia. The E. fetida were exposed to 0, 10, 20, 40, 60, and 80% treatments of MLBR plus cow manure for 28 d. Good motility and no m...

UNLABELLED Barrier-to-autointegration factor (BAF) is a DNA binding protein with multiple cellular functions, including the ability to act as a potent defense against vaccinia virus infection. This antiviral function involves BAF's ability to condense double-stranded DNA and subsequently prevent viral DNA replication. In recent years, it has become increasingly evident that dynamic phosphorylat...

The barrier to autointegration factor (BAF) is an essential cellular protein with functions in mitotic nuclear reassembly, retroviral preintegration complex stability, and transcriptional regulation. Molecular properties of BAF include the ability to bind double-stranded DNA in a sequence-independent manner, homodimerize, and bind proteins containing a LEM domain. These capabilities allow BAF t...

Barrier-to-autointegration factor (BAF) is a protein that has been proposed to compact retroviral DNA, making it inaccessible as a target for self-destructive integration into itself (autointegration). BAF also plays an important role in nuclear organization. We studied the mechanism of DNA condensation by BAF using total internal reflection fluorescence microscopy. We found that BAF compacts D...

The exposure of the aquatic ecosystem to heavy metal from both natural and anthropogenic activities are on rise have harmful health effects all organisms human. This study assessed concentrations metals (Fe, Pb, Cd, Cr, As Zn) in surface water, sediments fish tissues Ose River examined histopathological changes two species (Mormyrus rume Clarias garienpinus). Surface samples were collected proc...

The barrier-to-autointegration factor BAF binds to the LEM domain (Em(LEM)) of the nuclear envelope protein emerin and plays an essential role in the nuclear architecture of metazoan cells. In addition, the BAF(2) dimer bridges and compacts double-stranded DNA nonspecifically via two symmetry-related DNA binding sites. In this article we present biophysical and structural studies on a complex o...

Barrier-to-autointegration factor (BAF) is a DNA-bridging protein, highly conserved in metazoans. BAF binds directly to LEM (LAP2, emerin, MAN1) domain nuclear membrane proteins, including LAP2 and emerin. We used site-directed mutagenesis and biochemical analysis to map functionally important residues in human BAF, including those required for direct binding to DNA or emerin. We also tested wi...

The purpose of this research was to determine the content heavy metals and microbiological quality, compare requirements quality standard values according SNI 2729:2013 2705:2014, as well value Bioaccumulation Factor (BAF) maximum consumption limit fish giant prawns metal-concentrated. This researh used survey random sampling methods, i.e taking samples (tilapia, broom fish, prawns) at 3 (three...

Barrier-to-autointegration factor (BAF or BANF1) is highly conserved in multicellular eukaryotes and was first identified for its role in retroviral DNA integration. Homozygous BAF mutants are lethal and depletion of BAF results in defects in chromatin segregation during mitosis and subsequent nuclear envelope assembly. BAF exists both in phosphorylated and unphosphorylated forms with phosphory...
