Reason and Intuition01:37

Reason and Intuition

7.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

lncRNA - Long Non-coding RNAs

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.3K
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

430
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

pre-mRNA Processing02:01

pre-mRNA Processing

57.2K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

    • Neuroscience
    • Computational Biology
    • Bioengineering

    Background:

    • Miniscope calcium imaging offers insights into neural activity during behavior.
    • Underutilization of miniscopes may be due to a lack of user-friendly preprocessing software.
    • Optogenetic tools are rising alongside in vivo imaging techniques.

    Purpose of the Study:

    • To develop a no-code, end-to-end scalable pipeline for preprocessing large miniscope recordings.
    • To address the need for accessible and efficient miniscope data analysis software.
    • To lower the barrier for researchers using miniscope calcium imaging.

    Main Methods:

    • Developed the Miniscope Processing Suite (MPS), a novel pipeline.
    • Implemented Constrained Non-negative Matrix Factorization (CNMF) with Nonnegative Double Singular Value Decomposition (NNDSVD) initialization.
    • Utilized multi-lasso segmentation and parallelized temporal/spatial updates for efficient processing.

    Main Results:

    • MPS successfully processed a large dataset of 77 hours (7.26 TB) of miniscope recordings.
    • Analysis was completed in 55.6 hours on a standard workstation, averaging 0.72 min/min of recording.
    • MPS demonstrated processing speeds 10-20X faster than traditional pipelines.

    Conclusions:

    • MPS is the first no-code, scalable pipeline for large miniscope data preprocessing.
