New Insights into Atonic Postpartum Hemorrhage: Animal Model Construction Based on Placental Nanodelivery Systems

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a placenta‐targeted nanodelivery system co‐loading HMGB1 protein and the NLRP3 agonist nigericin to establish an animal model of atonic postpartum hemorrhage. The model accurately recapitulates clinical phenotypes, including prolonged labor and uterine contractility dysfunction, while revealing inflammatory activation in placental ...

Changes in some physiological and biochemical parameters of Avena sativa L. in conditions of salinity and soil acidity

open access: yesИзвестия высших учебных заведений. Поволжский регион: Естественные науки
Background. The accumulation of salts in soils is often accompanied by a change in pH to the alkaline side, technogenic salinization can be accompanied by an acidic reaction of the soil.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Mercury speciation in soils of the industrialised Thur River catchment (Alsace, France) [PDF]

open access: yes, 2006
Methylmercury (MeHg) and total Hg (THg) concentrations in soil profiles were monitored in the Thur River basin (Alsace, France), where a chlor-alkali plant has been located in the city of Vieux-Thann since the 1930s.

Experiences with liming in European countries - results of long-term experiments

open access: yesJournal of Forest Science, 2006
Liming was and still is carried out in many European forests since the beginning of the 1980s. Main objectives of compensation liming is to neutralize actual acidic deposition in order to prevent further soil acidification, to increase base saturation ...

Non‐Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films

open access: yesAdvanced Materials, EarlyView.
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.
