Prenatal factors affecting the probability of survival between birth and weaning in rabbits

World Rabbit Science, 2023
The aim of this study was to analyse the relationships between kit birth weight and litter size with kit survival from birth to weaning, and to estimate the effects of place of birth, nest quality, cannibalism, lactation, parity order, season and sex.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

New records of the lollipop catshark Cephalurus cephalus (Scyliorhinidae) from the Gulf of California, Mexico Nuevos registros del tiburón renacuajo Cephalurus cephalus (Scyliorhinidae) en el golfo de California, México

Revista Mexicana de Biodiversidad, 2012
On February 11th 2007, 13 neonates and 4 adults of Cephalurus cephalus were collected using a benthic sledge, during one oceanographic cruise (Talud X, St. 12) in the mid Gulf of California, Mexico (28°01'36" N, 111°51'50" W). The lollipop catsharks were

Factors associated with maternal reported small size at birth in Nigeria using nationally representative survey data

Discover Public Health
Background Small size at birth is an important indicator of neonatal health and survival, particularly in low- and middle-income countries. It is a preventable public health problem linked with higher risks of infant mortality and developmental delays ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Birth size and breast cancer risk: Re-analysis of individual participant data from 32 studied [PDF]

, 2008
Background Birth size, perhaps a proxy for prenatal environment, might be a correlate of subsequent breast cancer risk, but findings from epidemiological studies have been inconsistent.

Assessing reproductive performance and predictive models for litter size in Landrace sows under tropical conditions [PDF]

Animal Bioscience
Objective Litter size and piglet loss at birth significantly impact piglet production and are closely associated with sow parity. Understanding how these traits vary across different parities is crucial for effective herd management.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
