The processes of oocyte growth, acquisition of meiotic competence and meiotic maturation are regulated by a large number of molecules. One of them could be calcineurin consisting of catalytic subunit A (Aα, Aβ, Aγ isoforms) and regulatory subunit B (B1, B2 isoforms). Calcineurin is involved in the meiotic maturation of oocytes in invertebrates or in lower vertebrates. In the mammalian oocytes, ...
Reactivation of fetal hemoglobin genes has been proposed as a potential therapeutic procedure in patients with β-thalassemia, sickle cell disease or other βhemoglobinopathies. In vitro model systems based on small plasmid globin gene constructs have previously been used in human and mouse erythroleukemic cell lines to study the molecular mechanisms regulating the expression of the fetal human g...
The first class of nonassociative simple Moufang loops was discovered by L. Paige in 1956 [9], who investigated Zorn’s and Albert’s construction of simple alternative rings. M. Liebeck proved in 1987 [7] that there are no other finite nonassociative simple Moufang loops. We can briefly describe the class as follows: For every finite field F, there is exactly one simple Moufang loop. Recall Zorn...
1. Introduction. By a labeled graph we shall mean a finite (non-empty) graph Γ, without loops or multiple edges, each of whose edges is labeled by an integer greater than or equal to 2. Let the vertices of Γ be s 1 , s 2 ,. .. , s n , and let the label on an edge with endpoints s i and s j be m ij ≥ 2. Define ab m to be the word abab. .. of length m. Then the Artin group AΓ associated with the ...
We compute the relative divergence and the subgroup distortion of Bestvina-Brady subgroups. We also show that for each integer n ≥ 3, there is a free subgroup of rank n of some right-angled Artin group whose inclusion is not a quasi-isometric embedding. This result answers the question of Carr about the minimum rank n such that some rightangled Artin group has a free subgroup of rank n whose in...
Abstract We show that in theories of axionlike particles (ALPs) coupled to electrons at tree-level, the one-loop effective coupling photons is process dependent: relevant for decay processes, g aγ (D) , differs significantly from appearing phenomenologically important Primakoff process, (P) . this has implications physics massive ALPs hot and dense environments, such as supernovae. derive, a co...
Background: In the previous study, we have shown that the presence of A allele at position -588 in γ-globin gene was highly frequent and closely associated with fetal hemoglobin elevation among β-thalassemia intermedia patients. Therefore, we decided to investigate whether this allele (A allele at -588) could result in an increase in γ-globin gene expression to ameliorate the severity of the di...
