Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

The Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

The Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Craniofacial growth, modeling, and estimation of milestones

The Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

The Anatomical Record, EarlyView.
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

ZBED6 Knockout Promotes Skeletal Muscle Development in Bama Pigs by Relieving Transcriptional Repression of CDKN1A

Animal Research and One Health, EarlyView.
Integrated transcriptomic and functional analyses identify CDKN1A as a direct target of ZBED6 in Bama pigs. ZBED6 knockout relieves transcriptional repression of CDKN1A, thereby promoting myogenic differentiation and skeletal muscle development.

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Assembly and Maintenance of Myofibrils in the Heart

Cytoskeleton, EarlyView.
ABSTRACT The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30 years to explain the sequence of events.

Model‐Informed Evaluation of Hydroxyurea Exposure During Lactation

Clinical Pharmacology &Therapeutics, EarlyView.
Hydroxyurea is a cornerstone therapy for sickle cell anemia; however, evidence guiding its use during lactation remains limited. This study aimed to develop a population pharmacokinetic (PK) model to characterize hydroxyurea disposition in maternal plasma and breast milk, and to quantify infant exposure under clinically relevant breastfeeding scenarios.
