A scenario for an evolutionary selection of ageing.

Signs of ageing become apparent only late in life, after organismal development is finalized. Ageing, most notably, decreases an individual's fitness. As such, it is most commonly perceived as a non-adaptive force of evolution and considered a by-product of natural selection.

Scalable computational algorithms for geospatial COVID-19 spread using high performance computing.

A nonlinear partial differential equation (PDE) based compartmental model of COVID-19 provides a continuous trace of infection over space and time. Finer resolutions in the spatial discretization, the inclusion of additional model compartments and model stratifications based on clinically relevant categories contribute to an increase in the number of unknowns to the order of millions. We adopt a parallel scalable solver that permits faster solutions for these high fidelity models.

RNA Interference (RNAi) Screening in Cultured Drosophila Cells.

Genetic perturbation assays have been crucial to the discovery of molecular pathways that drive diverse biological processes. RNA interference (RNAi)-mediated depletion of gene products represents a powerful means of elucidating gene function, as it allows one to systematically probe the phenotypic effects resulting from the functional loss of specific targets. The relative ease of use of RNAi technologies in cultured cells has allowed the design and implementation of genome-wide investigations to systematically reveal gene function.

Decentralised hepatitis C testing and treatment in rural Cambodia: evaluation of a simplified service model integrated in an existing public health system.

Background: Direct-acting antiviral treatment for hepatitis C virus (HCV) has provided the opportunity for simplified models of care delivered in decentralised settings by non-specialist clinical personnel. However, in low-income and middle-income countries, increasing overall access to HCV care remains an ongoing issue, particularly for populations outside of urban centres. We therefore aimed to implement a simplified model of HCV care via decentralised health services within a rural health operational district in Battambang province, Cambodia.

High sustained viral response rate in patients with hepatitis C using generic sofosbuvir and daclatasvir in Phnom Penh, Cambodia.

Safe and efficacious pan-genotypic direct-acting antiviral (DAA) regimens, such as sofosbuvir and daclatasvir (SOF + DCV), facilitate simplified models of care for hepatitis C virus (HCV). However, in Cambodia access to HCV testing and treatment has typically been low. In response, Médecins Sans Frontières (MSF) implemented a HCV testing and treatment pilot project in Phnom Penh, Cambodia in 2016.
