Genomics

36.2K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Additional Subnuclear Structures

4.6K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Evolutionary Relationships through Genome Comparisons

5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Statistical Software for Data Analysis and Clinical Trials

517
Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Area of Science:

  • Health Sciences
  • Information Retrieval
  • Systematic Reviews

Background:

  • Comprehensive literature searches are critical for accurate systematic reviews in health sciences.
  • Limited database coverage can lead to the omission of relevant studies.
  • The necessity of supplementary databases for thorough literature reviews is debated.

Purpose of the Study:

  • To explore methods for retrieving publications not indexed in PubMed and Embase.
  • To examine database coverage across different specialties.
  • To determine effective search strategies for systematic reviews.

Main Methods:

  • Analysis of Cochrane reviews (2017-2022) from public health, incontinence, hepato-biliary, and stroke groups.
  • Manual searching of included publications in PubMed and Embase.
  • Utilizing additional databases (Cochrane Library, PsycInfo, CINAHL, ClinicalTrials.gov) for unretrieved publications.

Main Results:

  • PubMed and Embase provided a mean coverage of 71.5% across specialties (range: 64.5%-75.9%).
  • An average of 5.8% of publications were not found in any studied database.
  • Coverage varied significantly among supplementary databases.

Conclusions:

  • PubMed and Embase offer substantial publication coverage for systematic reviews.
  • Supplementary databases are crucial for increasing the retrieval of relevant studies.
  • Utilizing additional databases enhances the comprehensiveness of literature searches.
