Classifying Matter by State02:49

Classifying Matter by State

103.3K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

The Atomic Theory of Matter

128.0K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

What is Matter?

58.3K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...

States of Matter

Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.
Scientists have discovered a fourth state of matter, plasma, that occurs naturally in the interiors...

Area of Science:

  • Gastroenterology and Immunology
  • Stem Cell Biology
  • Microbiome Research

Background:

  • Acute graft-versus-host disease (GVHD) targets gastrointestinal (GI) crypts essential for intestinal mucosa renewal.
  • Intestinal stem cell research has advanced understanding of microbiome-immune interactions in GVHD pathophysiology.
  • Serum biomarkers predicting long-term GVHD outcomes are emerging from GI tract studies.

Purpose of the Study:

  • To explore the role of intestinal stem cells and their interactions with the microbiome and immune system in GVHD.
  • To investigate GI-tract-derived serum biomarkers for predicting GVHD outcomes.
  • To elucidate new mechanisms of crypt biology relevant to GVHD.

Main Methods:

  • Review of recent advances in intestinal stem cell identification and culture.
  • Analysis of studies focusing on microbiome and immune system interactions in GVHD.
  • Examination of research on GI-tract-derived serum biomarkers for GVHD prediction.

Main Results:

  • GVHD targets crypt stem cells crucial for intestinal mucosal regeneration.
  • Interactions between the microbiome and innate/adaptive immunity are central to GVHD.
  • Identified serum biomarkers highlight protective cellular elements and GVHD targets within the GI tract.

Conclusions:

  • Serum biomarkers offer insights into crypt biology and GVHD mechanisms.
  • These biomarkers can guide the design of clinical trials for GVHD.
  • Findings support improved strategies for GVHD prevention and treatment.
