On the importance of including both sexes in animal studies – insights from home‐cage monitoring

Biological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Integrative analysis of single-nucleus RNA-seq and bulk RNA-seq reveals germline cells development dynamics and niches in the Pacific oyster gonad

iScience
Summary: Gametogenesis drives the maturation of germ cell precursors into functional gametes, facilitated by interactions with the niche environment. However, the molecular mechanisms, especially in invertebrates, remain incompletely understood.

Preserved Spermatogenesis and Hormonal Function in Men Receiving a Pretomanid Regimen (BPaMZ) for Pulmonary Drug‐Resistant Tuberculosis

Clinical Pharmacology &Therapeutics, EarlyView.
Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...

Analyses of the development and glycoproteins present in the ovarian follicles of Poecilia vivipara (Cyprinodontiformes, Poeciliidae)

Pesquisa Veterinária Brasileira, 2011
The morphofunctional aspects of oogenesis of Poecilia vivipara were studied aiming to understand the reproductive biology and development of species with internal fertilization, particularly those belonging to the family Poeciliidae.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

Ultrastructural changes in female hepatocytes during ovarian maturation of Steindachnerina insculpta (Pisces: Curimatidae) Mudanças ultra-estruturais nos hepatócitos de fêmeas de Steindachnerina insculpta (Pisces: Curimatidae) durante a maturação ovariana

Brazilian Journal of Biology, 2006
During gonadal maturation the females of Steindachnerina insculpta, a teleost of the Furnas reservoir, Minas Gerais, Brazil, show low hepatosomatic and high gonadossomatic indexes, suggesting possible transference of hepatic substances to the ovaries. In
