On Wielandt’s join theorem for fusion systems and localities

open access: yesForum of Mathematics, Sigma
Saturated fusion systems are categories modeling properties of conjugacy of p-elements in finite groups. It was shown by Chermak that there are group-like structures called regular localities associated to saturated fusion systems.

Subgroup separability, knot groups, and graph manifolds

open access: yes, 2000
This paper answers a question of Burns, Karrass and Solitar by giving examples of knot and link groups which are not subgroup-separable. For instance, it is shown that the fundamental group of the square knot complement is not subgroup separable.

On groups with all subgroups almost subnormal [PDF]

open access: yesJournal of the Australian Mathematical Society, 2004
AbstractIn this paper we consider groups in which every subgroup has finite index in the nth term of its normal closure series, for a fixed integer n. We prove that such a group is the extension of a finite normal subgroup by a nilpotent group, whose class is bounded in terms of n only, provided it is either periodic or torsion-free.

Finite groups with subgroups supersoluble or subnormal

open access: yesJournal of Algebra, 2009
The paper studies the structure of finite groups whose non-subnormal subgroups lie in some subclasses of the class \(\mathcal U\) of finite supersoluble groups. These subclasses are \(\mathcal U\) itself, the class of PST-groups (i.e. groups in which the property of permuting with Sylow subgroups is transitive), the class of PT-groups (i.e.

Immune activation and inflammation in patients with cardiovascular disease are associated with elevated phenylalanine-to-tyrosine ratios

open access: yesPteridines, 2013
Higher serum neopterin concentrations and kynurenine-to-tryptophan (Kyn/Trp) ratios are associated with increased mortality in patients with coronary artery disease (CAD). Preferentially, Th1-type cytokine interferon-γ stimulates tryptophan breakdown and

Groups of infinite rank with finite conjugacy classes of subnormal subgroups

open access: yes, 2015
A group is called a V-group if it has finite conjugacy classes of subnormal subgroups. It is proved here that if G is a periodic soluble group in which every subnormal subgroup of infinite rank has finitely many conjugates, then G is a V-group, provided ...

Metabolic Linkage and Correlations to Storage Capacity in Erythrocytes from Glucose 6-Phosphate Dehydrogenase-Deficient Donors

open access: yesFrontiers in Medicine, 2018
ObjectiveIn glucose 6-phosphate dehydrogenase (G6PD) deficiency, decreased NADPH regeneration in the pentose phosphate pathway and subnormal levels of reduced glutathione result in insufficient antioxidant defense, increased susceptibility of red blood ...

Groups with normal subgroups possessing subnormal complements

open access: yes, 1973
J. Wiegold has characterized groups in which every normal subgroup is a direct factor as the restricted direct products of simple groups. In this paper, it is proved that for a group G G to have the structure above, it is sufficient ...
