Allometric trajectories of body and head morphology in three sympatric Arctic charr (Salvelinus alpinus (L.)) morphs

open access: yesEcology and Evolution, 2017
A study of body and head development in three sympatric reproductively isolated Arctic charr (Salvelinus alpinus (L.)) morphs from a subarctic lake (Skogsfjordvatn, northern Norway) revealed allometric trajectories that resulted in morphological ...

Does the size of the femoral head correlate with the incidence of avascular necrosis of the proximal femoral epiphysis in children with developmental dysplasia of the hip treated by closed reduction?

open access: yesJournal of Children's Orthopaedics, 2020
Purpose The purpose of this study was to identify if any correlation between size of the proximal femoral epiphysis and avascular necrosis (AVN) exists.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

open access: yesFEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Indirect fitness benefits of cognitive investment: Head size predicts adaptive nest-site selection in Barn Swallows (Hirundo rustica)

open access: yesAvian Research
Cognitive traits such as brain size are hypothesized to influence avian reproductive strategies, yet the ecological mechanisms linking neural investment to fitness under natural conditions remain underexplored.

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

open access: yesFEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Plant spacing in broccoli: —Affects yield, head size, earliness

open access: yesCalifornia Agriculture, 1961
Spacing of plants affects both the total yield and the size of broccoli heads according to recent field tests. These results are important because the freezing industry generally prefers heads of smaller size than those shipped for fresh marketing.

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

open access: yesFEBS Open Bio, EarlyView.
MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Sex-related head size and shape dimorphism in Mapaná snakes (Bothrops asper) kept in captivity

open access: yesRevista Colombiana de Ciencias Pecuarias, 2013
Background: sexual size dimorphism in snakes is generally well documented, however, sexual shape dimorphism has been poorly studied. As snakes are considered gape-limited predators, identifying patterns of sexual size and head shape dimorphism can help ...
