Abstract A subgroup X of a group G is called transitively normal if in any Y such that $$X\le Y$$ X≤Y and subnormal . Thus all subgroups are only normality transitive relation every (i.e. $$\overline{T}$$ xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:...

A subgroup H of a group G is called ss-quasinormal in G if there is a subgroup B of G such that G = HB and H permutes with every Sylow subgroup of B; H is called weakly s-permutable in G if there is a subnormal subgroup T of G such that G = HT and H ∩ T ≤ HsG, where HsG is the subgroup of H generated by all those subgroups of H which are s-permutable in G. We fix in every non-cyclic Sylow subgr...

BACKGROUND/AIM Placental syndromes (PS) are characterized by endothelial dysfunction complicating placental dysfunction. Possible markers for endothelial dysfunction and amount of trophoblast are fibronectin and plasminogen activator inhibitor-2 (PAI-2), respectively. We aimed (1) to determine whether in women with recurrent PS (rPS), this complication is preceded by deviating fibronectin- and ...

Let $$\sigma =\{\sigma _i |i\in I\}$$ be some partition of all primes $${\mathbb {P}}$$ and G a finite group. A subgroup H is said to $$ -subnormal in if there exists chain $$H=H_0\le H_1\le \cdots \le H_n=G$$ such that either $$H_{i-1}$$ normal $$H_i$$ or $$H_i/(H_{i-1})_{H_i}$$ _j$$ -group for $$j \in I$$ $$i = 1, \ldots , n$$ . We call group $$T_{\sigma }$$ every G. In this paper, we analyse...

It has long been suggested that abnormal functions of the pineal gland may be implicated in the pathophysiology of schizophrenia. We present evidence proposing that diminished melatonin secretion may be associated with the pathophysiology of a subgroup of schizophrenic patients characterized by cerebral atrophy and ventricular enlargement, negative symptoms, impaired cognitive and psychosexual ...

Abstract If $$\sigma = \{ {\sigma }_{i} : i \in I \}$$ σ = { i : ∈ I } is a partition of the set $$\mathbb {P}$$ P all prime num...

Let G be a group with all subgroups subnormal. A normal subgroup N of G is said to be G-minimax if it has a finite G-invariant series whose factors are abelian and satisfy either max-G or minG. It is proved that if the normal closure of every element of G is G-minimax then G is nilpotent and the normal closure of every element is minimax. Further results of this type are also obtained.

We prove that a torsion group G with all subgroups subnormal is a nilpotent group or G = N(A1×· · ·×An) is a product of a normal nilpotent subgroup N and pi -subgroups Ai , where Ai = A (i) 1 · · ·A (i) mi G , A (i) j is a Heineken–Mohamed type group, and p1, . . . , pn are pairwise distinct primes (n ≥ 1; i = 1, . . . , n; j = 1, . . . ,mi and mi are positive integers).

serum concentration of fsh, lh, testosterone, prolactin, acth, cortisol, tsh, t4, t3 and resin t3 uptake were measured in 146 men who were exposed to vesicants used by the iraqi regime a few days t04 weeks prior to testing. clinical and laboratory findings had confirmed the use of mustard gas. mean serum concentrations of fsh, lh, tsh and prolactin were not significantly different from normal v...
