Animal cognition and animal minds [PDF]

open access: yes, 1997
Psychology, according to a standard dictionary definition, is the science of mind and behavior. For a major part of the twentieth century, (nonhuman) animal psychology was on a behavioristic track that explicitly denied the possibility of a science of ...

Effect of High Environmental Temperature on Egg Production, Serum Lipoproteins and Follicle Steroid Hormones in Laying Hens

open access: yesThe Journal of Poultry Science, 2011
The aim of this study was to establish which aspect of egg production, plasma lipoproteins and preovulatory follicle steroid hormones in laying hens is altered by thermal environment. In experiment 1, Single Comb White Leghorn hens (80-90wk of age) were

Classifying biogeographic realms of the endemic fauna in the Afro‐Arabian region

open access: yesEcology and Evolution, 2020
Aim Understanding diversity patterns and identifying the environmental factors that shape these patterns are essential for ecology and conservation. The Afro‐Arabian region comprises one of the most important biogeographic areas connecting continents ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

EFFECT OF HOTLY SUMMER IN ASSIUT ON HEALTH STATUS, PRODUCTIVITY AND BEHAVIOR OF FRIESIAN DAIRY CATTLE AND THE EVALUATION OF TRADITIONAL [PDF]

open access: yesAssiut Veterinary Medical Journal, 2008
Thirty mid-lactation Friesian cows, 178 day post-partum were randomlyassigned to three equal groups (N= 10 per group). All animals wereblocked for age (6 year old), stage of milk yield and average bodyweight.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Self-Administration of a Boar Priming Pheromone Stimulates Puberty in Gilts without Boar Exposure

open access: yesAnimals, 2023
Labor is in short supply in animal agriculture. One time-consuming task is estrus detection in gilts. Stimulation with a live boar causes the onset of puberty in young gilts. Typically, a live boar is used to stimulate and identify estrus in the gilts by

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A Comparison of the Anorexic Effects of Chicken, Porcine, Human and Bovine Insulin on the Central Nervous System of Chicks

open access: yesThe Journal of Poultry Science, 2009
The aim of the present study was to determine if some naturally-occurring substitutions of amino acid residues of insulin could act differentially within the central nervous system (CNS) of neonatal chicks to control ingestive behavior ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
