Cryopreservation of common carp sperm [PDF]

open access: yes, 2003
Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...

Protein Glutamylation: From Cytoskeleton to Signaling

open access: yesMed Research, EarlyView.
Tubulin glutamylation, γ‐glutamylation, and nontubulin glutamylation are distinct yet interconnected post‐translational modifications that regulate diverse physiological and pathological processes, including cytoskeletal organization, cell cycle progression, immunity, metabolism, and disease development.

Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Optimal irradiation parameters for the development of the sterile insect technique in the seedcorn maggot Delia platura (Diptera: Anthomyiidae)

open access: yesPest Management Science, EarlyView.
X‐ray irradiation of Delia platura pupae showed that 20 Gy induces high sterility while maintaining male quality and competitiveness, establishing optimal parameters for sterile insect technique implementation in North America. Abstract BACKGROUND The seedcorn maggot, Delia platura Meigen (Diptera: Anthomyiidae), is a sporadic but economically ...

Variation in sperm whale (Physeter macrocephalus) coda vocalizations and social structure in the North Atlantic Ocean [PDF]

open access: yes, 2009
This study aimed at complementing studies of sperm whale social and vocal behaviour that were restricted to the Pacific Ocean. The characteristic multi-pulsed structure of sperm whale clicks allows for estimation of whales' size from measurements of ...

The Heritability of Mating Behaviour in a Fly and Its Plasticity in Response to the Threat of Sperm Competition [PDF]

open access: yes, 2014
Phenotypic plasticity is a key mechanism by which animals can cope with rapidly changeable environments, but the evolutionary lability of such plasticity remains unclear.

Mating history shapes Wolbachia‐induced cytoplasmic incompatibility and female fitness in an insect pest

open access: yesPest Management Science, EarlyView.
Mating order and remating of females by males with different endosymbiont associations strongly shape Wolbachia‐induced cytoplasmic incompatibility, female fitness and offspring sex ratio. An incompatible first mating was weakly affected if followed by a compatible mating and vice versa, indicating strong first‐male sperm precedence with consequences ...

A review on studies of behavioural ecology of Centrobolus (Diplopoda, Spirobolida, Pachybolidae) in southern Africa [PDF]

open access: yesArthropods, 2019
Forty-two studies on fire millipedes are reviewed in which mechanisms of selection; sperm competition and cryptic female choice were studied. Approaches to: (1) quantify size dimorphism and find the selection pressures operating on the sexes, (2 ...

Bayesian Sperm Competition Estimates

open access: yesGenetics, 2003
Abstract We introduce a Bayesian method for estimating parameters for a model of multiple mating and sperm displacement from genotype counts of brood-structured data. The model is initially targeted for Drosophila melanogaster, but is easily adapted to other organisms. The method is appropriate for use with field studies where the number
