Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

Journal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Hypoplasia of the maxillary antrum.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1983
Hypoplasia of the maxillary antrum is uncommon, but its recognition is important as patients with this condition are often inappropriately given repeated courses of antibiotics and decongestants for so-called 'chronic sinusitis'. Orbital enlargement secondary to hypoplasia of the maxillary antrum, which must not be mistaken for the presence of an ...

Mastication‐Induced Brain Blood Flow Changes Before and After Surgical‐Orthodontic Treatment in Skeletal Class III Patients: A Pilot Longitudinal Study

Journal of Oral Rehabilitation, EarlyView.
In 22 patients with skeletal Class III malocclusion, chewing‐induced brain blood flow (BBF) was measured before and after surgical‐orthodontic treatment. Patients with low pre‐treatment BBF tended toward an increase post‐treatment (+3.4%), while those with high pre‐treatment BBF tended toward a decrease (−16.4%), indicating pre‐treatment BBF as a ...
