Cells taken from the lungs of people with chronic obstructive pulmonary disease (COPD) have a larger accumulation of ...

Fungi have been around for many millions of years, with the incremental process of evolution honing and improving their ...

Here the authors provide cryo electron microscopy structural information on soybean CESA1, CESA3, and CESA6 and find substantial differences between the structure of these CESA homotrimers and the ...

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 ...

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 ...

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 ...

The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells ... Most prokaryotic cells have a rigid cell wall that surrounds the plasma membrane and ...

In this study we performed a comparative analysis of the composition and architecture of the cell walls of each structure by confocal and quantitative ... with a Leica SP5 confocal laser scanning ...
