Variance01:15

Variance

The deviations show how spread out the data are about the mean. A positive deviation occurs when the data value exceeds the mean, whereas a negative deviation occurs when the data value is less than the mean. If the deviations are added, the sum is always zero. So one cannot simply add the deviations to get the data spread. By squaring the deviations, the numbers are made positive; thus, their sum will also be positive.The standard deviation measures the spread in the same units as the data.
Attachment of Sister Chromatids02:57

Attachment of Sister Chromatids

As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules.  Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall of a...

Couple01:29

Couple

A couple is a pair of parallel forces equal in magnitude but in opposite directions. The forces are separated by a perpendicular distance, known as the couple's arm. The couple causes a rotation force or moment that rotates the body about an axis perpendicular to the plane of the forces. The resulting moment is referred to as the couple moment. The SI unit of a couple moment is the Newton-meter (N-m).
A typical example to understand this concept is tightening a bolt with a lug wrench. A force...
Indeterminate Structure01:18

Indeterminate Structure

Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium.  Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and some...
Ending Relationships01:28

Ending Relationships

The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Area of Science:

  • Immunology and Vaccinology
  • Computational Biology and Bioinformatics
  • Tropical Neglected Diseases

Background:

  • Hookworm disease is a significant tropical neglected disease with common reinfection rates, necessitating effective vaccine development.
  • Understanding immune responses to hookworm vaccine candidates is challenging due to the parasite's complex life cycle.
  • Reverse vaccinology (RV) and bioinformatics offer promising tools for dissecting immune responses and identifying vaccine targets.

Purpose of the Study:

  • To identify hookworm antigens with immunogenic potential using bioinformatics.
  • To investigate the interaction between identified hookworm antigens and dendritic cell (DC) receptors.
  • To computationally assess the potential of hookworm antigens for vaccine design.

Main Methods:

  • Selected Necator americanus Glutathione S-Transferase-1 (Na-GST-1) as a model antigen due to its known immunogenicity.
  • Utilized immunoinformatic tools to perform docking analysis between Na-GST-1 and fifteen different DC receptors.
  • Evaluated binding affinities to predict interactions and potential immune responses (Th1/Th2).

Main Results:

  • Seven DC receptors (TLR2, TLR3, TLR4, TLR7, DEC-205, CD206, CD36) showed strong predicted binding affinities with Na-GST-1.
  • These interactions suggest a correlation between docking affinity and the predicted immunogenicity of Na-GST-1.
  • The study demonstrated a computational approach for assessing antigen-DC receptor engagement.

Conclusions:

  • Computational analysis provides valuable insights into DC receptor-antigen interactions relevant to hookworm vaccine design.
  • Early in silico strategies can effectively assess the potential of hookworm antigens for engaging DC receptors.
  • These findings support the advancement of hookworm vaccine candidates and control efforts for neglected tropical diseases.
