The effect of souvenaid on functional brain network organisation in patients with mild Alzheimer's disease: a randomised controlled study. [PDF]

PLoS ONE, 2014
Synaptic loss is a major hallmark of Alzheimer's disease (AD). Disturbed organisation of large-scale functional brain networks in AD might reflect synaptic loss and disrupted neuronal communication.

Homeostasis balance, homeostasis imbalance or distinct motivational processes? Comments on Marks (2015) ‘Homeostatic Theory of Obesity’

Health Psychology Open, 2016
In his article, ‘Homeostatic theory of obesity’, Marks suggested that imbalances in homeostatic processes could explain weight gain and obesity. He proposes that over-consumption of high-caloric, low-nutrient and low satiating foods, combined with a ...

Game-theoretical description of the go-or-grow dichotomy in tumor development for various settings and parameter constellations

Scientific Reports, 2023
A medically important feature of several types of tumors is their ability to “decide” between staying at a primary site in the body or leaving it and forming metastases. The present theoretical study aims to provide a better understanding of the ultimate

Head circumference as an epigenetic risk factor for maternal nutrition

Frontiers in Nutrition, 2022
Nutrition indicators for malnutrition can be screened by many signs such as stunting, underweight or obesity, muscle wasting, and low caloric and nutrients intake. Those deficiencies are also associated with low socioeconomic status.

The Grand Pessimistic Induction [PDF]

, 2018
After decades of intense debate over the old pessimistic induction (Laudan, 1977; Putnam, 1978), it has now become clear that it has at least the following four problems.

Understanding the Multifaceted Process of Aging: Theories, Mechanisms, and Implications for Treatment

Al-SalamJournal for Medical Science
The aging process is a multifaceted biological phenomenon characterized by alterations at the molecular, cellular, and organ levels that culminate in a gradual, unavoidable, and unavoidable reduction in the body's capacity to react suitably to internal ...

Caloric curve for nuclear liquid-gas phase transition in relativistic mean-field hadronic model

, 2012
The main thermodynamical properties of the first order phase transition of the relativistic mean-field (RMF) hadronic model were explored in the isobaric, the canonical and the grand canonical ensembles on the basis of the method of the thermodynamical ...

Impaired maturation of resting-state connectivity in anorexia nervosa from adolescence to adulthood: differential mechanisms of consummatory vs. anticipatory responses through a symptom provocation paradigm

Frontiers in Behavioral Neuroscience
This functional magnetic resonance imaging (fMRI) study examined resting-state (RS) connectivity in adolescent and adult patients with anorexia nervosa (AN) using symptom provocation paradigms.

Time line of redox events in aging postmitotic cells

eLife, 2013
The precise roles that oxidants play in lifespan and aging are still unknown. Here, we report the discovery that chronologically aging yeast cells undergo a sudden redox collapse, which affects over 80% of identified thiol-containing proteins. We present

Dietary fat supplements influence weight gain and egg production, but not offspring sex ratios in Japanese quail, Coturnix coturnix japonica

Journal of Avian Biology, 2023
Sex ratio theory suggests that females should bias offspring sex ratios based on maternal condition and the availability of critical food resources. Work in birds indicates that females do, indeed, bias sex ratios according to maternal condition and food
