The Evidence for Evolution02:55

The Evidence for Evolution

48.4K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Convergent Evolution01:54

Convergent Evolution

33.1K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Eukaryotic Evolution01:24

Eukaryotic Evolution

42.5K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.
Contrary to the endosymbiont theory, the eukaryote-first hypothesis proposes that the simpler prokaryotic and...

Synteny and Evolution02:31

Synteny and Evolution

3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

1.4K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Standard Enthalpy of Formation02:37

Standard Enthalpy of Formation

49.6K
Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

Area of Science:

  • Neuroimaging
  • Epilepsy Diagnostics
  • Clinical Neuroscience

Background:

  • MRI plays a critical role in the etiological diagnosis and presurgical evaluation of epilepsy patients.
  • Advancements in MRI research offer potential to improve diagnostic yield and reduce MRI-negative findings in epilepsy care.
  • Rapid progress in MRI technology creates uncertainty regarding the clinical applicability of new developments.

Purpose of the Study:

  • To clarify current best practices for MRI in epilepsy patient care.
  • To outline future directions and potential advancements in MRI for epilepsy diagnostics.

Main Methods:

  • Review of modern MRI hardware, sequences, and postprocessing techniques.
  • Evaluation of ultra-high-field MRI and advanced sequences for diagnostic quality.
  • Analysis of computerized classifiers integrating anatomical and functional features for diagnostic validity.

Main Results:

  • Progress in diagnostic MRI for epilepsy is driven by hardware, sequence, and postprocessing innovations.
  • Ultra-high-field MRI and sophisticated sequences yield high-quality data for feature extraction.
  • Computerized classification of neuroimaging data shows high diagnostic validity, though enthusiasm for Diffusion Tensor Imaging and functional MRI in pre-surgical evaluation is tempered.

Conclusions:

  • An epilepsy-tailored MRI protocol at 3 Tesla with expert evaluation early in the disease course is crucial.
  • Future research should focus on standardizing MRI workups and implementing widely used postprocessing routines for multimodal data analysis.
