The Atacama Large Millimeter/submillimeter Array (ALMA) has uncovered a key piece of the puzzle in how rocky planets, such as ...

Fibroblast (NIH/3T3) cell cultures were performed for seventeen days to demonstrate the potential of cell attachment on surfaces and encapsulation in the wall of he microscopic scaffolds for blood ...

This survey of wood using a cryo-scanning electron microscope focused on: The Secondary Cell Wall: This is composed of mainly cellulose plus other complex sugars and is impregnated with lignin to make ...

In rare cases, these problems can lead to tracheal stenosis, a condition where the trachea narrows and a person struggles to breathe. Tracheal cancer is another rare condition that can affect the ...

Tulip trees have been around for millions of years, but a new analysis of their structure ... microscope. When they got to the tulip tree sample and examined its secondary cell wall, they were ...

Researchers undertaking an evolutionary survey of the microscopic ... Wall: This is composed of mainly cellulose plus other complex sugars and is impregnated with lignin to make the whole ...

The body of the rabbit trachea is therefore composed of a hyaline-cartilage structure primarily made of collagen II and bands of aggrecan, surrounded by a fibrous region composed of elastin and ...

When air enters the nose or mouth, it travels down the trachea, also known as the windpipe ... and the outer layer attaches to the inner wall of the rib cage. The space between the two membranes ...

This article explains the bronchi anatomy and function. It also describes different conditions that affect the bronchi and how they are treated. The bronchi begin at the base of the trachea at the ...

The nasal turbinates, trachea, proximal bronchus, and distal bronchus were evaluated and scored for histopathology and IHC by a blinded diagnostic pathologist (Rahe) using an Olympus BX41 microscope .

We have investigated the rate of MCC in the murine nasal cavity compared to the more distal airways (trachea). The rate of MCC in the nasal cavity (posterior nasopharynx, PNP) was ∼3–4× greater than ...
