Nutritional assessment models for diabetes and aging
Food Frontiers, Volume 3, Issue 4, Page 689-705, December 2022., 2022 Abstract Diabetes is a chronic disease, and its complexity and its various complications complicate studies in diabetes management. Aging is one of the main risk factors for diabetes, and elderly are a high‐risk group for developing the disease. In recent years, increasing evidence has revealed the underlying molecular basis for aging diabetes and its ...

Evolution, Volume 76, Issue 12, Page 3054-3066, December 2022., 2022 Abstract Gene repertoire turnover is a characteristic of genome evolution. However, we lack well‐replicated analyses of presence/absence patterns associated with different selection contexts. Here, we study ∼100 transcriptome assemblies across Macrostomum, a genus of simultaneously hermaphroditic flatworms exhibiting multiple convergent shifts in ...

Adhesive organ regeneration in Macrostomum lignano [PDF]
BMC Developmental Biology, 2016 Abstract Background Flatworms possess pluripotent stem cells that can give rise to all cell types, which allows them to restore lost body parts after injury or amputation. This makes flatworms excellent model systems for studying regeneration. In this study, we present the adhesive organs of a marine flatworm as a simple

Evolution of sex allocation plasticity in a hermaphroditic flatworm genus
Journal of Evolutionary Biology, Volume 35, Issue 6, Page 817-830, June 2022., 2022 Interspecific variation in both sex allocation and sex allocation plasticity in the hermaphroditic flatworm genus Macrostomum, including among closely related species, suggests that both sex allocation and sex allocation plasticity are evolutionarily labile. Moreover, self‐fertilization, but not mating strategy, predicts the evolution of sex allocation

Frequent origins of traumatic insemination involve convergent shifts in sperm and genital morphology
Evolution Letters, Volume 6, Issue 1, Page 63-82, February 2022., 2022 Abstract Traumatic insemination is a mating behavior during which the (sperm) donor uses a traumatic intromittent organ to inject an ejaculate through the epidermis of the (sperm) recipient, thereby frequently circumventing the female genitalia. Traumatic insemination occurs widely across animals, but the frequency of its evolution, the intermediate ...

A pan‐metazoan concept for adult stem cells: the wobbling Penrose landscape
Biological Reviews, Volume 97, Issue 1, Page 299-325, February 2022., 2022 ABSTRACT Adult stem cells (ASCs) in vertebrates and model invertebrates (e.g. Drosophila melanogaster) are typically long‐lived, lineage‐restricted, clonogenic and quiescent cells with somatic descendants and tissue/organ‐restricted activities.

Ecology and Evolution, Volume 11, Issue 18, Page 12285-12293, September 2021., 2021 Sexual contact commonly occurs among insects (Eberhard, 1994). However, descriptions of precopulatory oral sexual contact in invertebrates remain rare and the evidence for an evolutionary function of precopulatory oral sexual contact is still lacking.

Andrology, Volume 9, Issue 5, Page 1617-1630, September 2021., 2021 Abstract Background Spermatogenesis is an elaborately organized and tightly regulated differentiation process. The spermatogenesis duration is stable within a certain species but highly variable between species of the same family. Objectives In this study, the spermatogenesis duration of the Roborovski hamster was measured for the first time, and the ...

Omics‐based molecular analyses of adhesion by aquatic invertebrates
Biological Reviews, Volume 96, Issue 3, Page 1051-1075, June 2021., 2021 ABSTRACT Many aquatic invertebrates are associated with surfaces, using adhesives to attach to the substratum for locomotion, prey capture, reproduction, building or defence. Their intriguing and sophisticated biological glues have been the focus of study for decades.
