On some groups whose subnormal subgroups are contranormal-free [PDF]

open access: yesInternational Journal of Group Theory
If $G$ 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.

Groups with finitely many normalizers of non-subnormal subgroups [PDF]

open access: yesLe Matematiche, 2007
It is proved that a group G has finitely many normalizers of non-subnormal subgroups if and only if each subgroup of G either is subnormal or has finitely many conjugates; groups with this latter property have been completely described in [8].

Joins of $\sigma$-subnormal subgroups

open access: yes, 2023
Let $\sigma=\{\sigma_j\,:\, j\in J\}$ be a partition of the set $\mathbb{P}$ of all prime numbers. A subgroup $X$ of a finite group $G$ is~\textit{$\sigma$-subnormal} in $G$ if there exists a chain of subgroups $$X=X_0\leq X_1\leq\ldots\leq X_n=G$$ such that, for each $1\leq i\leq n-1$, $X_{i-1}\trianglelefteq X_i$ or $X_i/(X_{i-1})_{X_i}$ is a ...

Finite groups in which every self-centralizing subgroup is nilpotent or subnormal or a TI-subgroup [PDF]

open access: yes, 2021
summary:Let $G$ be a finite group. We prove that if every self-centralizing subgroup of $G$ is nilpotent or subnormal or a TI-subgroup, then every subgroup of $G$ is nilpotent or subnormal. Moreover, $G$ has either a normal Sylow $p$-subgroup or a normal

Hemodynamic changes in pregnancies with impaired fetal growth: A systematic review and meta-analysis. [PDF]

open access: yesActa Obstet Gynecol Scand
Maternal cardiovascular adaptation is altered in pregnancies complicated by impaired fetal growth. From the second trimester onwards, lower cardiac output and increased total peripheral vascular resistance emerge, highlighting the need for early hemodynamic monitoring and potential interventions in at‐risk pregnancies.

Survival of Hematologic Malignancy In Patients With Early-Stage Chronic Kidney Disease (SHIP-CKD). [PDF]

open access: yesCancer Med
ABSTRACT Background Chronic kidney disease (CKD) is a common comorbidity among cancer patients and may influence treatment options and outcomes. However, the independent effect of CKD in patients with hematologic malignancies remains unclear. Methods We conducted a retrospective cohort study using electronic medical records of 1238 adult patients ...
