Study on 25 (OH) Vitamin D Status in Hospitalizied Children with Acute Respiratory Infections: Preliminary Results [PDF]
Journal of Biomedical & Clinical Research, 2023 Our study aimed to determine and analyze the serum levels of 25 (OH) vitamin D and parathyroid hormone (PTH) to assess vitamin D deficiency as a risk factor for increased morbidity of acute respiratory infections (ARI) in childhood.

Finite groups whose maximal subgroups of even order are MSN-groups
Open Mathematics, 2022 A finite group GG is called an MSN-group if all maximal subgroups of the Sylow subgroups of GG are subnormal in GG. In this article, we investigate the structure of finite groups GG such that GG is a non-MSN-group of even order in which every maximal ...

Sex-Related Differences in Risk Factors Associated With Nonhealing or Recurrence of Hyperthyroidism in Patients With Graves' Disease Treated With Radioactive Iodine. [PDF]
Health Care SciAge and thyroid volume were independent risk factors for the occurrence of nonhealing or recurrence of hyperthyroidism (NHRH) in female patients. Only free thyroxine (FT4) was independently associated with the occurrence of NHRH in male patients. ABSTRACT Background To evaluate sex‐related differences in the risk factors associated with nonhealing or ...

On some groups whose subnormal subgroups are contranormal-free [PDF]
International Journal of Group TheoryIf $G$ is a group, a subgroup $H$ of $G$ is said to be contranormal in $G$ if $H^G = G$, where $H^G$ is the normal closure of $H$ in $G$. We say that a group is contranormal-free if it does not contain proper contranormal subgroups.

On the Finite Group Which Is a Product of Two Subnormal Supersolvable Subgroups
Mathematics, 2022 Let G be a finite group that is a product of two subnormal ( normal) supersolvable subgroups. The following are interesting topics in the study of the structure of G: obtaining the conditions in addition to guarantee that G is supersolvable and giving ...

Finite groups with given systems of generalised σ-permutable subgroups
Журнал Белорусского государственного университета: Математика, информатика, 2021 Let σ = {σi|i ∈ I } be a partition of the set of all primes ℙ and G be a finite group. A set ℋ of subgroups of G is said to be a complete Hall σ-set of G if every member ≠1 of ℋ is a Hall σi-subgroup of G for some i ∈ I and ℋ contains exactly one Hall ...

Joins of Almost Subnormal Subgroups [PDF]
Proceedings of the Edinburgh Mathematical Society, 1979 Following (1) we say that a subgroup H of a group G is almost subnormal in G if H is of finite index in some subnormal subgroup of G, or, equivalently, if |Hn : H| is finite for some n, where Hn is the n-th term of the normal closure series of H in G. The aim of this article is to prove, in answer to a question of R. Baer, the following analogue of the

Finite groups in which normality, permutability or Sylow permutability is transitive
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 Y. Li gave a characterization of the class of finite soluble groups in which every subnormal subgroup is normal by means of NE-subgroups: a subgroup H of a group G is called an NE-subgroup of G if NG(H) ∩ HG = H. We obtain a new characterization of these
