Mapping of structural arrangement of cells and collective calcium transients: an integrated framework combining live cell imaging using confocal microscopy and UMAP-assisted HDBSCAN-based approach.

Live cell calcium (Ca2+) imaging is one of the important tools to record cellular activity during in vitro and in vivo preclinical studies. Specially, high-resolution microscopy can provide valuable dynamic information at the single cell level. One of the major challenges in the implementation of such imaging schemes is to extract quantitative information in the presence of significant heterogeneity in Ca2+ responses attained due to variation in structural arrangement and drug distribution.

Analytics Pipeline for Visualization of Single Cell RNA Sequencing Data from Brochoaveolar Fluid in COVID-19 Patients: Assessment of Neuro Fuzzy-C-Means and HDBSCAN.

Since the mutation in SARS-COV2 poses new challenges in designing vaccines, it is imperative to develop advanced tools for visualizing the genetic information. Specially, it remains challenging to address the patient-to-patient variability and identify the signature for severe/critical conditions. In this endeavor we analyze the large-scale RNA-sequencing data collected from broncho-alveolar fluid.

Mathematical modeling of viral infection dynamics and immune response in SARS-CoV-2: A computational framework for testing drug efficacy.

SARS-CoV-2 has emerged to cause the outbreak of COVID-19, which has expanded into a worldwide human pandemic. Although detailed experimental data on animal experiments would provide insight into drug efficacy, the scientists involved in these experiments would be exposed to severe risks. In this context, we propose a computational framework for studying infection dynamics that can be used to capture the growth rate of viral replication and lung epithelial cell in presence of SARS-CoV-2.

Quantitative Confocal Microscopy for Grouping of Dose-Response Data: Deciphering Calcium Sequestration and Subsequent Cell Death in the Presence of Excess Norepinephrine.

Fluorescent calcium (Ca) imaging is one of the preferred methods to record cellular activity during in vitro preclinical studies, high-content drug screening, and toxicity analysis. Visualization and analysis for dose-response data obtained using high-resolution imaging remain challenging, due to the inherent heterogeneity present in the Ca spiking. To address this challenge, we propose measurement of cytosolic Ca ions using spinning-disk confocal microscopy and machine learning-based analytics that is scalable.

Leave against Medical Advice in Children: Rural Indian Perspective.

Objectives: To determine the burden and etiological factors of leave against medical advice (LAMA) in Indian children.

Methodology: In this prospective study, legal guardians of 528 patients who took the decision of LAMA were interviewed (using structured question answers based multi-option) and data were captured over a period of 16 months. The resultant database was analyzed using standard statistical methods.

Multiorgan dysfunction syndrome in sepsis: Is macrophage activation syndrome secondary to infection?

Objective: To assess macrophage activation syndrome (MAS) in septic shock leading to multiorgan dysfunction syndrome (MODS).

Methods: A prospective observational study was conducted at a tertiary care hospital to evaluate the MAS criteria in different stages of sepsis. Children aged 6 months to 12 years in different stages of septic shock were recruited.

Detection of Specific Templates in Calcium Spiking in HeLa Cells Using Hierarchical DBSCAN: Clustering and Visualization of CellDrug Interaction at Multiple Doses.

One of the major challenges in analyzing large scale intracellular calcium spiking data obtained through fluorescent imaging is to identify various patterns present in time series data. Such an analysis identifying the distinct frequency and amplitude encoding during cell-drug interaction study is expected to provide new insights into the drug action patterns over a time course. Here, we present the HDBSCAN clustering algorithm to find a clustering pattern present in calcium spiking obtained by confocal imaging of single cells.

Assessing chromite ore processing residue (COPR) waste dump site using electrical resistivity tomography (ERT): a case study from Umaran, Kanpur, India.

Leaching of chromium ions causes a serious threat to groundwater around chromite ore processing residue (COPR) dump sites in many countries. As a result, detailed subsurface characterization of the affected region is crucial for assessing the associated risks as well as initiating remedial measures. Though the conventional approaches (e.

Installation and first operation of the International Fusion Materials Irradiation Facility injector at the Rokkasho site.

The International Fusion Materials Irradiation Facility (IFMIF) linear IFMIF prototype accelerator injector dedicated to high intensity deuteron beam production has been designed, built, and tested at CEA/Saclay between 2008 and 2012. After the completion of the acceptance tests at Saclay, the injector has been fully sent to Japan. The re-assembly of the injector has been performed between March and May 2014.

International Fusion Materials Irradiation Facility injector acceptance tests at CEA/Saclay: 140 mA/100 keV deuteron beam characterization.

In the framework of the ITER broader approach, the International Fusion Materials Irradiation Facility (IFMIF) deuteron accelerator (2 × 125 mA at 40 MeV) is an irradiation tool dedicated to high neutron flux production for future nuclear plant material studies. During the validation phase, the Linear IFMIF Prototype Accelerator (LIPAc) machine will be tested on the Rokkasho site in Japan. This demonstrator aims to produce 125 mA/9 MeV deuteron beam.
