Introduction to force01:25

Introduction to force

Consider water flowing from a nozzle to a turbine vane. As the water hits the turbine vane, it exerts a force that causes it to move along the flow of direction. Force is an impact that changes an object's motion, shape, or orientation. Forces can be caused by physical contact, such as a push or pull, or through non-contact interactions, such as magnetic or gravitational forces. Force is a vector quantity with both magnitude and direction, and is measured in newtons (N) in the SI unit system.
An Introduction to Mechanics01:28

An Introduction to Mechanics

Humans have been making ships, shelters, pyramids, weapons, agricultural equipment, and many more items without recording the process or theory behind them for centuries. It would be challenging to document the evolution of mechanics from its origin to the present.
According to records, the history of mechanics starts with Aristotle (384–322 BC). He related mechanics to physical theory, aiming for a universal synthesis.
Newton defined mechanics as the branch of physical science that studies the...

Introduction to Statistics

The science of statistics involves collecting, analyzing, interpreting, and presenting data. The method of collecting, organizing, and summarizing data is called descriptive statistics. The systematic method of drawing inferences from the sample data and predicting unknown characteristics of a population is called inferential statistics.
In statistics, the collection of individuals or objects under study is called population. The idea of sampling is to select a portion of the larger population...

Newton's First Law: Introduction

Motion draws our attention. Motion itself can be beautiful, causing us to marvel at the forces needed to create spectacular sights, such as that of a dolphin jumping out of the water, the flight of a bird, or the orbit of a satellite. The study of motion is kinematics, but kinematics only describes the way objects move—their velocity and acceleration. Dynamics considers the forces that affect the motion of moving objects and systems. Newton's laws of motion are the foundation of dynamics. These...
Chromatography: Introduction01:10

Chromatography: Introduction

Chromatography is a technique used to separate compounds based on differences of partitioning between two phases, the stationary phase and the mobile phase.
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
Biostatistics: Overview01:20

Biostatistics: Overview

Biostatistics plays a crucial role in understanding and analyzing data in healthcare and biology. Biostatisticians conduct experiments, gather evidence, and draw meaningful conclusions using statistical methods and techniques. Different variables form the foundation of biostatistical analysis, allowing researchers to understand and interpret data effectively. These variables are classified into different types, each serving a specific purpose in statistical analysis.
Discrete variables are...

Area of Science:

  • Microbiology
  • Oral Health
  • Oncology

Background:

  • The human oral cavity harbors a highly diverse microbial ecosystem, including bacteria, fungi, and viruses.
  • Oral biofilms form on various surfaces, with their composition influenced by niche-specific conditions and material properties.
  • Advances in molecular techniques have significantly improved our understanding of oral microbial communities and host interactions.

Purpose of the Study:

  • To explore the role of the oral microbiome in maintaining health and its connection to head and neck cancers.
  • To investigate how microbial dysbiosis contributes to carcinogenesis.
  • To highlight the importance of understanding oral microbiology for cancer research.

Main Methods:

  • Utilized culture-independent molecular technologies such as 16S rRNA gene sequencing and shotgun metagenomics.
  • Employed multi-omics approaches to analyze oral microbial diversity and function.
  • Reviewed existing evidence linking oral microbiome alterations to head and neck cancer pathogenesis.

Main Results:

  • The oral microbiome exists in a state of dynamic equilibrium (eubiosis) in health, contributing to homeostasis.
  • Disruption of this balance (dysbiosis) is increasingly associated with head and neck cancer development.
  • Microbial dysbiosis may promote cancer through inflammation, immune modulation, and carcinogenic metabolites.

Conclusions:

  • Understanding the oral microbiome's role in health and disease is critical.
  • Oral microbial dysbiosis is a significant factor in head and neck cancer initiation and progression.
  • Further research into oral microbiology offers potential for novel diagnostic and therapeutic strategies for cancer.
