Petri net models and non linear genetic diseases

2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA), 2010
Understanding how an individual genetic make-up influences their risk of diseases, is a problem of paramount importance. Although machine-learning techniques are unable to uncover the relationships between genotype and disease, we can still build the best biochemical model automatically with the help of methods that identify the DNA sequence variations

Petri nets for modelling and analysing a complex system related to Alzheimer's disease

Proceedings of the 31st Annual ACM Symposium on Applied Computing, 2016
Alzheimer's disease is the most common form of dementia. It is among the major causes of death in the world. It has been proved that Alzheimer's is associated with elevated concentrations of homocysteine. Being part of a complex biological system, we can model it to study its behaviour and predict its deregulations earlier.

Petri net transition times as training features for multiclass models to support the detection of neurodegenerative diseases

Biomedical Physics & Engineering Express, 2022
Abstract This paper proposes the transition times of Petri net models of human gait as training features for multiclass random forests (RFs) and classification trees (CTs). These models are designed to support screening for neurodegenerative diseases.

Petri disease - destructive disease of young vineyards in Croatia

Glasilo biljne zaštite, 2011
Petrijeva bolest uzrok je propadanja ili slabijeg razvoja mladih trsova vinove loze, a javlja se uglavnom u prvim godinama nakon sadnje vinograda. Uzročnici bolesti su gljive Phaeomoniella chlamydospora i velik broj vrsta iz roda Phaeoacremonium, a danas je poznato da su spomenute gljive raširene svugdje u svijetu gdje se uzgaja vinova loza.

FIRST REPORT OF PHAEOACREMONIUM ALVESII ASSOCIATED WITH GRAPEVINE PETRI DISEASE IN IRAN

Journal of Plant Pathology, 2015
In June 2013, a survey was conducted for grapevine decline in Abadeh (Fars province, south-western Iran). Branch and trunk samples were collected from grapevines showing Petri disease symptoms, i.e. stunted growth, chlorotic leaves, and necrosis in cross-sectioned wood. Isolations were made from symptomatic wood tissue on malt extract agar (MEA).

Modeling transmission of directly transmitted infectious diseases using colored stochastic Petri nets

Mathematical Biosciences, 2003
In order to improve our understanding of directly transmitted pathogens within host populations, epidemic models should take into account individual heterogeneities as well as stochastic fluctuations in individual parameters. The associated cost results in an increasing level of complexity of the mathematical models which generally lack consistent ...

NovelPhaeoacremoniumspecies associated with Petri disease and esca of grapevine in Iran and Spain

Mycologia, 2009
Eight Phaeoacremonium (Pm.) isolates from grapevines in Iran and Spain were studied with morphological and cultural characteristics as well as phylogenetic analyses of combined DNA sequences of the actin and beta-tubulin genes. Two new species are described. Pm.

Activity of Trichoderma in the nursery for the control of Petri disease

2006
Studies have recently demonstrated that Phaeomoniella chlamydospora and Phaeoacremonium species are able to produce latent infections in cuttings at nursery level and in causing Petri disease. In these last years studies were carried out for the development of procedures and products to prevent and/or reduce the infection in the nursery. In this study,

Sensitivity of Petri disease pathogens to hot‐water treatments in vitro

Annals of Applied Biology, 2008
AbstractPetri disease pathogens (Phaeoacremonium spp. and Phaeomoniella chlamydospora) are able to colonize the vessels in the xylem of grapevine propagating material. Hot‐water treatment (HWT) protocols at 50°C for 30 min have been applied in grapevine nurseries to control these pathogens with variable results.
