Nowadays, oxyfluoride glasses have received much attention from photonic researchers as they benefit from the advantages of both oxide and fluoride glasses (low phonon energy in parallel with high mechanical and chemical durability). The purppose of this paper was to study the different glass compositions in SiO2-Al2O3-K2O-BaF2 system and i...

introduction wetlands are classified into four kinds of flows as subsurface, surface, vertical, and hybrid flows. usually, wetlands are planted with common reed (phragmites australis), a rhizomatose plant of the graminae which produces a good yield in green biomass and whose roots can reach a considerable depth and plays a significant role in the wetland self-purification. the treatment efficie...

Mammalian SWI/SNF (mSWI/SNF) complexes are ATP-dependent chromatin remodeling enzymes that critical for normal cellular functions. mSWI/SNF classified into three sub-families based on the presence of specific subunit proteins. The Brm- or Brg1-associated factor (BAF), ncBAF (non-canonical BAF), and polybromo-associated BAF (PBAF). biological roles different enzyme poorly described. We knocked d...

we used wild boars and roe deer as biomonitors of lead (pb), cadmium (cd), and mercury (hg)contamination in two major industrial sites in poland with different levels of toxic metal pollution. masurianlakes district, located far away from industry, was used as the reference site. levels of pb, cd, and hg in liver,kidney and muscle samples and in the stomach content of the animals were determine...

The small nematode Caenorhabditis elegans displays a spectrum of DNA damage responses similar to humans. In order to identify new DNA damage response genes, we isolated in a forward genetic screen 14 new mutations conferring hypersensitivity to ionizing radiation. We present here our characterization of lem-3, one of the genes identified in this screen. LEM-3 contains a LEM domain and a GIY nuc...

This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana.  The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...

The Bitterlich method was studied with multiple basal area factors (BAF) in 3 Pinus taeda L. plantations located the Midwest of Santa Catarina, Brazil using different management regimes: without thinning (1344 trees.ha-1), one (789 and two thinnings (475 trees.ha-1),. Using parameters obtained from censuses, we sought to verify data sample treatments for variables V.ha-1, G.ha-1, N.ha-1 “d” thr...

Constructed wetlands (CWs) are important plant filters used for wastewater treatment. The behavior of the Canna indica-planted CWs in face a highly variable composition industrial has yet to be understood. Here, we show effectiveness and unplanted vertical subsurface flow treatment Algiers petroleum refinery’s effluent. selected species was placed containing light expanded clay aggregate (LECA)...

► Two concentrations of weathered PCBcontaminated soil were amended with (0, 0.2, 0.7, 2.8, and 11.1% w/w) of biochar. ► Biochar additions decreased the uptake of PCBs into plant tissue by 89% after 50 days. ► Biochar amendment significantly decreased the bioavailability of PCBs to earthworms by 88% after 50 days of exposure. ► Biochar has potential to serve as a mitigation technology at Brownf...

Chromatin disorganization is one of the major alterations linked to prelamin A processing impairment. In this study we demonstrate that BAF is necessary to modulate prelamin A effects on chromatin structure. We show that when prelamin A and BAF cannot properly interact no prelamin A-dependent effects on chromatin occur; similar to what is observed in human Nestor Guillermo Progeria Syndrome cel...
