Using Machine Learning to Predict Mortality for COVID-19 Patients on Day 0 in the ICU

Nahal Mansouri, Sahand Jamal Rahi

Rationale: Given the expanding number of COVID-19 cases and the potential for new waves of infection, there is an urgent need for early prediction of the severity of the disease in intensive care unit (ICU) patients to optimize treatment strategies.Objecti ...

Personalized predictions of adverse side effects of the COVID-19 vaccines

Nahal Mansouri, Sahand Jamal Rahi

Background: Misconceptions about adverse side effects are thought to influence public acceptance of the Coronavirus disease 2019 (COVID-19) vaccines negatively. To address such perceived disadvantages of vaccines, a novel machine learning (ML) approach was ...

ELSEVIER SCI LTD2023

Symptom Prediction and Mortality Risk Calculation for COVID-19 Using Machine Learning

Nahal Mansouri, Sahand Jamal Rahi

Background: Early prediction of symptoms and mortality risks for COVID-19 patients would improve healthcare outcomes, allow for the appropriate distribution of healthcare resources, reduce healthcare costs, aid in vaccine prioritization and self-isolation ...

Automated neuron tracking inside moving and deforming C. elegans using deep learning and targeted augmentation

Ariane Andrée Marie Delrocq, Sahand Jamal Rahi

Reading out neuronal activity from three-dimensional (3D) functional imaging requires segmenting and tracking individual neurons. This is challenging in behaving animals if the brain moves and deforms. The traditional approach is to train a convolutional n ...

The multimodality cell segmentation challenge: toward universal solutions

Maxime Emmanuel Scheder, Jun Ma, Sahand Jamal Rahi, Xin Yang, Vojislav Gligorovski, Marco Labagnara

Cell segmentation is a critical step for quantitative single-cell analysis in microscopy images. Existing cell segmentation methods are often tailored to specific modalities or require manual interventions to specify hyper-parameters in different experimen ...

Minimal shuttle vectors for Saccharomyces cerevisiae

Lorenzo Scutteri, Patrick Daniel Barth, Sahand Jamal Rahi

Sophisticated genetic engineering tasks such as protein domain grafting and multi-gene fusions are hampered by the lack of suitable vector backbones. In particular, many restriction sites are in the backbone outside the polylinker region (multiple cloning ...

A simplified version of rapid susceptibility testing of bacteria and yeasts using optical nanomotion detection

Sandor Kasas, María Inés Villalba, Sahand Jamal Rahi, Vojislav Gligorovski

We present a novel optical nanomotion-based rapid antibiotic and antifungal susceptibility test. The technique consisted of studying the effects of antibiotics or antifungals on the nanometric scale displacements of bacteria or yeasts to assess their sensi ...

A convolutional neural network segments yeast microscopy images with high accuracy

Matthias Minder, Anne-Florence Raphaëlle Bitbol, Martin Weigert, Sahand Jamal Rahi, Mateusz Kozinski, Vojislav Gligorovski, Nicola Dietler, Chun Hei Michael Chan, Denis Alain Henri Lucien Joly, Ahmad Sadeghi, Augoustina Maria Economou

The identification of cell borders ('segmentation') in microscopy images constitutes a bottleneck for large-scale experiments. For the model organism Saccharomyces cerevisiae, current segmentation methods face challenges when cells bud, crowd, or exhibit i ...

Automated plasmid design for marker-free genome editing in budding yeast

Lazar Stojkovic, Mahsa Geramimanesh, Sahand Jamal Rahi, Vojislav Gligorovski, Marco Labagnara

Scarless genome editing in budding yeast with elimination of the selection marker has many advantages. Some markers such as URA3 and TRP1 can be recycled through counterselection. This permits seamless genome modification with pop-in/pop-out, in which a DN ...

Inferring how animals deform improves cell tracking

Sahand Jamal Rahi

Tracking cells is a time-consuming part of biological image analysis, and traditional manual annotation methods are prohibitively laborious for tracking neurons in the deforming and moving Caenorhabditis elegans brain. By leveraging machine learning to dev ...

The optimal strategy balancing risk and speed predicts DNA damage checkpoint override times

Sahand Jamal Rahi

Cells have built-in mechanisms for checking for errors during replication, but these checkpoints can slow down reproduction. A theory accounting for optimal checkpoint strategies is presented and tested against observations in budding yeast. Checkpoints ar ...

Multidimensional characterization of inducible promoters and a highly light-sensitive LOV-transcription factor

Sahand Jamal Rahi, Vojislav Gligorovski

The ability to independently control the expression of different genes is important for quantitative biology. Using budding yeast, we characterize GAL1pr, GALL, MET3pr, CUP1pr, PHO5pr, tetOpr, terminator-tetOpr, Z(3)EV, blue-light inducible optogenetic sys ...
