Plant and Animal Reproductive Strategies: Lessons from Offspring Size and Number Tradeoffs

Frontiers in Ecology and Evolution, 2017
The tradeoff between offspring size and number is ubiquitous and manifestly similar in plants and animals despite fundamental differences between the evolutionary histories of these two major life forms.

The cell cycle inhibitor RB is diluted in G1 and contributes to controlling cell size in the mouse liver

Frontiers in Cell and Developmental Biology, 2022
Every type of cell in an animal maintains a specific size, which likely contributes to its ability to perform its physiological functions. While some cell size control mechanisms are beginning to be elucidated through studies of cultured cells, it is ...

Transposons, Genome Size, and Evolutionary Insights in Animals [PDF]

Cytogenetic and Genome Research, 2015
The relationship between genome size and the percentage of transposons in 161 animal species evidenced that variations in genome size are linked to the amplification or the contraction of transposable elements. The activity of transposable elements could represent a response to environmental stressors.

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

Analyzing Modeled Torque Profiles to Understand Scale-Dependent Active Muscle Responses in the Hip Joint

Biomimetics, 2022
Animal locomotion is influenced by a combination of constituent joint torques (e.g., due to limb inertia and passive viscoelasticity), which determine the necessary muscular response to move the limb. Across animal size-scales, the relative contributions

Bone and Soft Tissue Neoplasms in Infants Versus Older Children: A Report From the Cancer in Young People in Canada Program

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Infant bone and soft tissue neoplasms present distinct clinical challenges and lack large‐scale data to inform treatment decisions. This study aims to characterize bone and soft tissue neoplasms in infants in Canada and to compare their outcomes with those of older pediatric patients.

Effect of group size on pecking-injury prevalence and severity in male fattening turkeys (

Poultry Science
Agonistic interactions between fattening turkeys in large flocks often result in injurious pecking. In wild turkeys, ranking fights within familiar sibling groups appear from the 8th week of life, but the attacked bird usually escapes from superior birds.

Efficacy of platelet concentrates in bone healing: A systematic review on animal studies – Part B: Large-size animal models

Platelets, 2018
In the presence of large bone defects, delayed bone union, or nonunion and fractures, bone reconstruction may be necessary. Different strategies have been employed to enhance bone healing among which the use of autologous platelet concentrates (APCs ...
