Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

open access: yesThe FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

Periodontitis and Adverse Pregnancy Outcomes: Mechanistic Evidence

open access: yesJournal of Periodontal Research, EarlyView.
This narrative review aims to describe mechanisms linking periodontal diseases in pregnancy with adverse pregnancy outcomes. ABSTRACT Periodontal diseases, including both gingivitis and periodontitis, occur commonly among pregnant individuals. Both gingivitis and periodontitis are associated with adverse pregnancy outcomes (APOs) such as early ...

Ectopic production of human chorionic gonadotropin in transitional cell carcinoma of the bladder. An immunohistochemical study

open access: yes, 1990
A retrospective histopathological and clinical analysis of 43 patients with transitional cell carcinoma of the bladder, attending our institution between March 1986 and April 1989, was performed.

Effects of Video‐Based Health Education on Birth Outcomes and Anaemia Status of Mothers in Dirashe District South Ethiopia: A Cluster Randomized Controlled Trial

open access: yesMaternal &Child Nutrition, EarlyView.
ABSTRACT Undernutrition and infections during pregnancy result in low birth weight (LBW) and maternal anaemia. Social behaviour change communication (SBCC) can promote recommended health practices, potentially improving maternal and neonatal outcomes.

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Beta-Subunit of Human Chorionic Gonadotropin in Malignant Lymphoma : An Immunohistochemical Study [PDF]

open access: yes
We present a rare case of a 77-year-old Japanese man with malignant lymphoma associated with production of beta-subunit of human chorionic gonadotropin in the cytoplasms of lymphoma cells in the lymph nodes.

Ectopic human chorionic gonadotropin in breast carcinoma

open access: yes, 1979
Immunoreactive human chorionic gonadotropin (hCG) was found in 9 of 65 surgically removed malignant breast tumors. Concentrations ranged from 5 to greater than 500 mIU hCG/g tumor. hCG was measured by a beta-chain specific readiommunoassay.

Myasthenia Gravis and Thymoma

open access: yesMuscle &Nerve, Volume 74, Issue 4, Page 1156-1173, October 2026.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.
