مطالعه انکوباسیون به منظور بررسی اثر کمپوست قارچ مصرفی(smc) و بیوچار باگاس نیشکر(b) بر فراهمی واجزاء مختلف فسفر معدنی در یک خاک آهکی انجام گرفت. تیمارها شامل b1 و b2 (معادل15 و 30 تن در هکتار)، smc1، smc2 (معادل20 و 40 تن در هکتار) و شاهد(c) بودند. فسفر قابل جذب و محلول در آب، ph و شکلهای فسفر معدنی شامل دیکلسیم فسفات(ca2-p)، اکتاکلسیم فسفات(ca8-p)، فسفات آلومینیم(al-p)، فسفات آهن(fe-p)، ...
Ataxia telangiectasia mutated (ATM) and DNA-dependent protein kinase (DNA-PK) play a crucial role in the initial stages of cell response, when cells are exposed to DNA insult such as ionizing radiation (IR) and chemical agents. We previously demonstrated that ATM requires BAAT1 for its activation in response to IR. In the present study, BAAT1 was found to bind to the DNA-PK catalytic subunit (D...
Cohesin's Smc1, Smc3, and kleisin subunits create a tripartite ring within which sister DNAs are entrapped. Evidence suggests that DNA enters through a gate created by transient dissociation of the Smc1/3 interface. Release at the onset of anaphase is triggered by proteolytic cleavage of kleisin. Less well understood is the mechanism of release at other stages of the cell cycle, in particular d...
Faithful transmission of chromosomes during eukaryotic cell division requires sister chromatids to be paired from their generation in S phase until their separation in M phase. Cohesion is mediated by the cohesin complex, whose Smc1, Smc3 and Scc1 subunits form a tripartite ring that entraps both DNA double strands. Whereas centromeric cohesin is removed in late metaphase by Scc1 cleavage, meta...
The cohesin complex is responsible for the fidelity of chromosomal segregation during mitosis. It consists of four core subunits, namely Rad21/Mcd1/Scc1, Smc1, Smc3, and one of the yeast Scc3 orthologs SA1 or SA2. Sister chromatid cohesion is generated during DNA replication and maintained until the onset of anaphase. Among the many proposed models of the cohesin complex, the 'core' cohesin sub...
BACKGROUND Patent ductus arteriosus is a life-threatening condition frequent in premature newborns but also present in some term infants. Current mouse models of this malformation generally lead to perinatal death, not reproducing the full phenotypic spectrum in humans, in whom genetic inheritance appears complex. The ductus arteriosus (DA), a temporary fetal vessel that bypasses the lungs by s...
