Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

open access: yesThe 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.

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

open access: yesThe Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

open access: yesAnimal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Testosterone Deficiency: A Common, Unrecognised Syndrome?

open access: yes, 2009
Context: Testosterone deficiency syndrome (TDS) is highly prevalent in ageing men. Associated symptoms may significantly impair quality of life and may affect the function of multiple organ systems. In addition, TDS may have an impact on life expectancy.

More‐than‐gender? Moving beyond gendered expectations of divergent learners in early childhood education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In this paper, we explore how neurodivergent ways of being in early education are often gendered. The intersectionalities of gender and neurodivergence often lead to fixed expectations that perpetuate binary interpretations, pathologisations, missed diagnoses and a lack of curated support.

Late-onset hypogonadism

open access: yesMenopause Review, 2017
In Poland, the number of men over the age of 50 years exceeds 6 million. It is estimated that about 2-6% of this population develops symptoms of late-onset hypogonadism (LOH). In men, testosterone deficiency increases slightly with age.
