Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

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

open access: yesBiological Reviews, EarlyView.
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.

Performance of entire, surgically castrated and immunologically castrated male pigs

open access: yes, 1999
The castration of boars ceased to be a management strategy within the Australian pig industry more than 30 years ago because of the production efficiencies associated with leaving males intact, especially in regard to average daily gain (ADG), depth of ...

Utterance evolution: the road to generative, combinatorial communicators

open access: yesBiological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Pathophysiologic Consequences of Early Coarctation Stenting in a Longitudinal Porcine Model

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Novel stent technologies offer early intravascular treatment options for coarctation (COA). Mid‐to‐long‐term cardiovascular responses to early COA stent interventions are undefined. Aims We studied a porcine model of COA, with and without early stent implantation with serial dilation to adult aortic diameters, aiming to define ...

Protective Effect of Phytic Acid in Cardiovascular Diseases: A Systematic Review

open access: yesChemFoodChem, EarlyView.
ABSTRACT Cardiovascular diseases (CVDs) are a cluster of ailments that impact the heart and blood vessels and are a primary public health problem of mortality on a global scale. Phytic acid, a dietary constituent frequently present in foods like seeds, has been linked to many pharmacological attributes, including anti‐cancer, antioxidant, anti ...

Conventional and deep-litter pig production systems: the effects on fat deposition and distribution in growing female large white X landrace pigs

open access: yes, 2008
Minimising variability in carcass quality to better meet market specifications is a priority for Australian pig producers, however issues with variability in carcass fat distribution have recently been raised, particularly in the belly primal.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...
