The costs of extra‐pair behaviours in birds

Biological Reviews, Volume 101, Issue 5, Page 2300-2312, October 2026.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

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

Cytoskeleton, Volume 83, Issue 10, Page 779-794, October 2026.
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 ...

Evaluating Reproductive Health Recommendations in CPGs for Sickle Cell Disease: An Umbrella Review

Clinical and Public Health Guidelines, Volume 3, Issue 4, October 2026.
ABSTRACT Background Individuals with sickle cell disease or trait (SCD/T) face significant reproductive health risks, highlighting the need to assess the best available evidence on their reproductive health needs. Objectives To assess the quality of SCD/T clinical practice guidelines and evaluate the key characteristics and quality of their ...

Potentially Toxic Elements and Male Reproductive Toxicity: Mechanisms, Implications, and Protective Strategies: A Narrative Review

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Potentially toxic elements impair male reproductive function through oxidative stress, DNA damage, mitochondrial dysfunction, inflammation, endocrine disruption and epigenetic alterations. Antioxidants, phytochemicals, chelating agents and healthy lifestyle interventions may help mitigate testicular toxicity and preserve fertility.

Brown Adipose Tissue: Molecular Mechanisms of Regulation, Physiological Functions, and Therapeutic Targets

MedComm, Volume 7, Issue 10, October 2026.
This review systematically covers three core dimensions of brown adipose tissue (BAT): multilayered regulatory mechanisms governing brown adipocyte differentiation and phenotypic identity, physiological functions and signaling pathways in mediating thermogenesis and systemic metabolic crosstalk between BAT and multiple organs, and emerging clinical in ...

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

The assembly of tetrameric human L‐lactate dehydrogenase is regulated by ionic strength, β‐NADH binding, cyclic peptides, and long‐chain dicarboxylates

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Lactate dehydrogenases catalyze the reduction of pyruvate to lactate, the generation of which is of importance for the energetic metabolism of malignant cells. In particular, human cancer cells overexpress lactate dehydrogenase A (hLDH‐A), whose catalytic activity depends on its assembly into the corresponding homotetramer (denoted as hLDH‐5),

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

Environmental Toxicology, Volume 41, Issue 10, Page 1105-1118, October 2026.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.
