Modelling territorial behaviour of animals in variable environments

Animal Behaviour, 1999
We present an individual-based model describing the distribution and resource gain of territorial individuals in situations where the rank order of territory quality changes over time. The model integrates both competitive (territory-holding ability) asymmetries and a memory function.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Behavioural adaptations of livestock to environmental stressors: implications for welfare and productivity

Journal of Applied Animal Research
Livestock are frequently exposed to environmental stressors that adversely affect their welfare and productivity. This review examines the behavioural adaptations of livestock to these stressors and their implications for animal welfare and performance ...

Association of health behaviour with heart rate variability: a population-based study

BMC Cardiovascular Disorders, 2010
Background Reduced heart rate variability (HRV), a non-invasive marker of autonomic dysfunction, and an unhealthy lifestyle are associated with an increased morbidity and mortality of cardiovascular diseases (CVD).

Lifestyle habits of Croatian diabetic population: observations from the Croatian Adult Health Survey [Životne navike osoba sa šećernom bolepću u Republici Hrvatskoj: zapažanja iz Hrvatske zdravstvene ankete] [PDF]

, 2009
The aim of this study was to assess the behavioural risk factors in Croatian diabetic population and to compare them with the lifestyle habits of individuals with no known history of diabetes.

Levels and mechanisms of behavioural variability

, 2010
The behaviour of animals is the result of adaptations and constraints. To what extent a particular behaviour pattern can be attributed to the relative strengths of these two forces is crucial with respect to understanding the evolution of behaviour. Moreover, in the still young history of the study of animal behaviour, different conceptual approaches ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Nicotinergic Modulation of Attention-Related Neural Activity Differentiates Polymorphisms of DRD2 and CHRNA4 Receptor Genes.

PLoS ONE, 2015
Cognitive and neuronal effects of nicotine show high interindividual variability. Recent findings indicate that genetic variations that affect the cholinergic and dopaminergic neurotransmitter system impact performance in cognitive tasks and effects of ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
