Classifying Matter by State02:49

Classifying Matter by State

103.8K
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

128.4K
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?01:13

What is Matter?

103.1K
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...

Fineness of Cement01:15

Fineness of Cement

520
The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.

Area of Science:

  • Environmental Health
  • Endocrinology
  • Reproductive Biology

Background:

  • Emerging evidence links air pollution to increased diabetes risk.
  • Gestational diabetes mellitus (GDM) poses risks to maternal and fetal health.
  • Fine particulate matter (PM2.5) is a major air pollutant with potential health impacts.

Purpose of the Study:

  • To investigate the effects of PM2.5 exposure on glucose metabolism in a GDM rat model.
  • To examine the impact of PM2.5 on pancreatic glucose transporter 2 (GLUT2) expression.
  • To elucidate the underlying mechanisms involving inflammation and oxidative stress.

Main Methods:

  • GDM rats were exposed to low-dose PM2.5 or saline control.
  • Assessed maternal and fetal weight, blastocyst counts, and postprandial blood glucose (PBG).
  • Analyzed blood markers (IL-6, BRT), pancreatic oxidative stress (GSH-Px, MDA), and GLUT2 expression.

Main Results:

  • PM2.5 exposure reduced maternal and fetal weight gain.
  • Increased PBG, inflammatory markers (IL-6, PBMCs, platelets), and pancreatic inflammation were observed.
  • PM2.5 led to decreased pancreatic glutathione peroxidase (GSH-Px), increased malondialdehyde (MDA), and reduced GLUT2 expression.

Conclusions:

  • PM2.5 exposure exacerbates glycemic dysregulation in GDM rats.
  • Inflammation and oxidative stress mediate the adverse effects of PM2.5 on GDM outcomes.
  • PM2.5 exposure is associated with adverse maternal and fetal consequences in GDM.
