Multiciliated cells (MCCs) in the respiratory epithelium play crucial roles in the innate defense system against airborne pathogens and pollutants. Each MCC possesses 200-300 cilia on their apical surface, which beat in a synchronized manner to clear mucus with foreign particles from the respiratory tract. Ciliary dysfunction leads to serious respiratory diseases including chronic infection as ...

background: endometrial development has an important role in blastocyst adhesion and implantation. during ivf cycles, endometrial development is enhanced by progesterone. objective: the aim of this study was to compare ultrastructural and morphometrical characteristics of mice uterine endometrium in natural cycle with those in superovulated cycles received progesterone or sildenafil. materials ...

Carbons are considered as anode active materials in potassium-ion batteries (PIBs). Here, the correlation between material properties of disordered (non-graphitic) and ordered graphitic carbons their electrochemical performance carbon||K metal cells is evaluated. First, obtained from heat treatment petroleum coke at temperatures 800 to 2800 °C analyzed regarding microstructure surface propertie...

The airway epithelium comprises of different cell types and acts as a physical barrier preventing pathogens, including inhaled particles microbes, from entering the lungs. Goblet cells submucosal glands produce mucus that traps which are expelled respiratory tract by ciliated cells. Basal act progenitor cells, differentiating into epithelial types, to maintain homeostasis following injury. Adhe...
