Structure of the Hantavirus Nucleoprotein Provides Insights into the Mechanism of RNA Encapsidation

Cell Reports, 2016
Hantaviruses are etiological agents of life-threatening hemorrhagic fever with renal syndrome and hantavirus cardiopulmonary syndrome. The nucleoprotein (N) of hantavirus is essential for viral transcription and replication, thus representing an ...

Periodically Varying Externally Imposed Environmental Effects on Population Dynamics [PDF]

, 2004
Effects of externally imposed periodic changes in the environment on population dynamics are studied with the help of a simple model. The environmental changes are represented by the temporal and spatial dependence of the competition terms in a standard equation of evolution.

Parasite infection in a cell population with deaths and reinfections [PDF]

arXiv, 2021
We introduce a model of parasite infection in a cell population, where cells can be infected, either at birth through maternal transmission, from a contact with the parasites reservoir, or because of the parasites released in the cell medium after the lyses of infected cells.

Complex evolution and epidemiology of Dobrava-Belgrade hantavirus: definition of genotypes and their characteristics. [PDF]

, 2013
Dobrava-Belgrade virus (DOBV) is a human pathogen that has evolved in, and is hosted by, mice of several species of the genus Apodemus. We propose a subdivision of the species Dobrava-Belgrade virus into four related genotypes – Dobrava, Kurkino ...

Hantaan virus glycoprotein Gc induces NEDD4‐dependent PTEN ubiquitination and degradation to escape the restriction of autophagosomes and facilitate viral propagation

The FASEB Journal, Volume 39, Issue 1, 15 January 2025.
The proposed model of HTNV induced PTEN degradation and PTEN‐regulated autophagy in progeny virus production: In HTNV‐infected HK‐2 cells, the viral Gc glycoprotein specifically promotes NEDD4 mediated ubiquitination and degradation of PTEN. Disruption of PTEN expression prevents autophagosome formation and increases HTNV production, whereas ...

Hantavirus Infection in the Republic of Georgia

Emerging Infectious Diseases, 2009
We describe a laboratory-confirmed case of hantavirus infection in the Republic of Georgia. Limited information is available about hantavirus infections in the Caucasus, although the infection has been reported throughout Europe and Russia.

A sharp threshold for a modified bootstrap percolation with recovery [PDF]

Journal of Statistical Physics, Volume 157, Issue 3 (2014), pp 531-570, 2015
Bootstrap percolation is a type of cellular automaton on graphs, introduced as a simple model of the dynamics of ferromagnetism. Vertices in a graph can be in one of two states: `healthy' or `infected' and from an initial configuration of states, healthy vertices become infected by local rules.

Influence of Host and Landscape‐Associated Factors in the Infection and Transmission of Pathogens: The Case of Directly Transmitted Virus in Mammals

Veterinary Medicine and Science, Volume 11, Issue 1, January 2025.
The figure shows the effects (increasing upward arrow or decreasing downward arrow) the most common host traits, landscape attributes, climatic features and anthropogenic variables recorded in the review had on the infection and transmission of directly transmitted virus to mammals.

Effect of Predators of Juvenile Rodents on the Spread of the Hantavirus Epidemic [PDF]

arXiv, 2005
Effects of predators of juvenile mice on the spread of the Hantavirus are analyzed in the context of a recently proposed model. Two critical values of the predation probability are identified. When the smaller of them is exceeded, the hantavirus infection vanishes without extinguishing the mice population.

PDE model for multi-patch epidemic models with migration and infection-age dependent infectivity [PDF]

arXiv, 2023
We study a stochastic epidemic model with multiple patches (locations), where individuals in each patch are categorized into three compartments, Susceptible, Infected and Recovered/Removed, and may migrate from one patch to another in any of the compartments.
