Maternal Toxoplasma gondii Infection Perturbs Foetal and Maternal Foetal Interface Metabolism, Exposing the Foetus to Kynurenine

British Journal of Biomedical Science
IntroductionToxoplasma gondii infection during pregnancy can result in abortion or congenital infection. Events in the maternal-foetal interface, which form a selective barrier between the maternal and foetal circulations and where critical immunological

Caesarean Scar Ectopic Pregnancy in Early Gestation: A Scoping Review of Definitions and Diagnostic Approach

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 5, Page 888-899, April 2026.
ABSTRACT Background Caesarean scar ectopic pregnancy (CSEP) is defined by the implantation and development of a gestational sac inside a caesarean scar defect, but variations in classification systems and diagnostic criteria exist. Objectives This study aimed to systematically review the different criteria used in the medical literature to diagnose ...

Kisspeptin Restores Placental mTOR Signaling and Improves Glucose Homeostasis Mediators Disrupted by Maternal Hypothyroidism in Rats

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Reduced placental mTOR signaling is associated with intrauterine growth restriction and impaired maternal and placental metabolism. Since maternal hypothyroidism induces intrauterine growth restriction, and maternal treatment with kisspeptin‐10 (Kp10) has been shown to improve feto‐placental development in hypothyroid rats, this study ...

Variation in seed abundance predicts yolk fatty acid composition in a wild population of birds

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Bird embryos develop inside eggs, which contain maternal substances that can shape offspring phenotype and fitness. Yolk fatty acids are a key energy source for the developing embryo, with omega‐6 (ω‐6) and omega‐3 (ω‐3) polyunsaturated fatty acids (PUFAs) obtained exclusively from the diet.

A stress paradox: the dual role of the unfolded protein response in the placenta

Frontiers in Endocrinology
The placenta is a temporary organ that forms during pregnancy and is essential for fetal development and maternal health. As an endocrine organ, proper placental function requires continual production, folding, and transport of proteins and lipids ...

Importance of placental evaluation in pregnancies at high risk for placenta accreta spectrum: Expert clinical perspective

Pregnancy, Volume 2, Issue 2, March 2026.
Abstract Background Placenta accreta spectrum (PAS) is a leading cause of obstetric morbidity and peripartum hysterectomy. Rising cesarean delivery rates, advanced maternal age, and assisted reproductive technologies have increased its incidence. Early, standardized diagnosis is essential for multidisciplinary planning and improved outcomes, yet formal

Prospective of indigenous African wild food plants in alleviation of the severe iron deficiency anaemia in Sub‐Saharan Africa

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 486-498, March 2026.
Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

Mapping the next forest generation reveals multiple regeneration gaps across German forests

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Our study provides the first nationwide, high‐resolution assessment of forest regeneration, offering a valuable baseline for monitoring forest development. The regeneration density and indicator maps enable forest managers and policymakers to identify regeneration deficits, prioritise adaptive management interventions and contribute to the development ...

Effects of Ungulate Herbivores on Temperate Forest Understory Vegetation—Implications From a Large‐Scale Wildlife Exclosure Experiment in Central Europe

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Fenced ungulate exclosure (foreground) with unfenced control plot (background). ABSTRACT Question Ungulates play a key role in influencing understory vegetation and ecosystem dynamics in temperate forests. However, how soil conditions modulate ungulate effects on understory communities remains insufficiently understood.

Biogeography and host associations of Russula subsection Xerampelinae based on large‐scale analysis of UNITE sequence data

New Phytologist, Volume 249, Issue 5, Page 2547-2558, March 2026.
Summary Estimating fungal geographic ranges and niche potential is limited by the ephemeral nature of fruiting bodies. While environmental DNA offers broader insights, species‐level identification remains difficult due to uncertain sequence clustering thresholds, low interspecific variation in barcoding regions, and limited taxonomic resolution.
