The dependence of the phagocytosis of particulate materials on their size was studied. Rabbit alveolar macrophages (AMs) obtained by lung lavage were cultured in suspensions or monolayers with Latex particles of 1 micron or 2 microns in diameter. After culturing AMs with 10(7)(-5) X 10(9) Latex particles per ml for 15 to 360 minutes, the number of phagocytized particles in each of 100 individua...

The microRNAs (miRNAs) are small, non-coding RNAs that modulate protein expression by interfering with target mRNA translation or stability. miRNAs play crucial roles in various functions such as cellular, developmental, and physiological processes. The spatial expression patterns of miRNAs are very essential for identifying their functions. The expressions of miR-302 and miR-367 are critical i...

Morphologies featured in bicomponent 2D ultrathin films were reproduced on 3D non-woven microfibre structures. Fibre networks were constructed by electrospinning hydrophobised cellulose derivatives, trimethylsilyl cellulose (TMSC) and cellulose triacetate (CTA), dissolved in a common solvent. Diverse morphologies were obtained depending on the polymer blend ratio: electrospinning of TMSC produc...

To allow a further understanding of the pathogenesis of impaired stimulated locomotion by polymorphonuclear leukocytes (PMNs) in human neonates, we studied cellular orientation by neonatal PMNs in response to well-defined chemotactic gradients (Zigmond orientation chambers) and characterized the cytoplasmic microtubule (MT) complex of neonatal PMNs during cell orientation and movement. PMN susp...

Fenestrated capillaries are provided with two types of regular discontinuities: fenestrae with negatively charged diaphragms, and transendothelial channels fitted with two diaphragms, of which the luminal one is uncharged. These structures are expected to affect macromolecular exchanges on the basis of size and charge. We have detected variations in the surface density of fenestrations and tran...
