Light Acquisition02:16

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
Phase Contrast and Differential Interference Contrast Microscopy01:26

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
Glassware Calibration01:11

Glassware Calibration

Accurate calibration of glassware, such as volumetric flasks, pipettes, and burettes, is essential to ensure accurate measurements in the analytical laboratory. Calibration helps maintain consistency across measurements and prevents errors arising from inaccurate volumes.
Volumetric flasks: Volumetric flasks are designed to prepare aqueous solutions of precise volumes accurately with a calibration line on the neck. To calibrate a volumetric flask, it is important to fill it with distilled...
Sight Distance in a Vertical Curve01:29

Sight Distance in a Vertical Curve

Sight distance on vertical curves is critical in roadway design. It ensures drivers can see far enough ahead to identify and respond to hazards effectively. This directly impacts safety, driver comfort, and the overall efficiency of the transportation network.Vertical curves are classified into crest and sag curves based on their geometry. For crest curves, sight distance is determined by the line of sight between a driver's eye and a small object on the road's surface. Design parameters for...

Area of Science:

  • Hepatology
  • Immunology
  • Mathematical Biology

Background:

  • Chronic hepatitis-B viral (HBV) infection impacts an estimated 250 million people worldwide.
  • The liver's unique microenvironment, or 'liver terrain,' features gradients of oxygen and nutrients within sinusoids, influencing immune responses.
  • Specialized liver cells, Kupffer cells (KC) and liver sinusoidal endothelial cells (LSECs), play critical roles in pathogen detection and immune modulation at blood entry points.

Purpose of the Study:

  • To investigate the intricate relationship between the liver terrain's spatial and structural features and the dynamics of HBV infection.
  • To understand how HBV exploits specific liver microenvironmental conditions for invasion and persistence.
  • To identify potential therapeutic strategies by illuminating HBV's reliance on the liver terrain.

Main Methods:

  • Utilized mathematical modeling to simulate and analyze spatial and structural variations within the liver terrain.
  • Integrated multi-scale modeling approaches to dissect complex interactions between HBV and liver microenvironment components.
  • Coordinated modeling insights with experimental observations to validate findings.

Main Results:

  • HBV targets key metabolic proteins, particularly at periportal sites where KC and LSECs are concentrated.
  • Failure of KC and LSEC spatial configurations may inadvertently facilitate HBV invasion and entrenchment.
  • Mathematical modeling revealed subtle, competing dynamics governing HBV infection within the liver terrain.

Conclusions:

  • The liver terrain's specific structural and spatial configurations are critical factors in HBV infection dynamics.
  • Understanding these microenvironmental dependencies offers potential avenues for developing novel strategies to combat HBV.
  • Multi-scale modeling is a promising approach to unraveling HBV's complex interactions within the liver.
