A case involving a 41-year-old man with yellow nail syndrome (YNS) is reported. YNS is a rare disorder characterized by yellow, dystrophic nails, peripheral lymphedema and bronchiectasis with recurrent lower respiratory tract infections. YNS is often misdiagnosed because the syndrome is not well known.

The aim of this study was to evaluate the effects of 9-cis retinoid acid (9-cis RA) and all-trans RA (ATRA) on proliferation, migratory ability, synthesis of extracellular matrix, intracellular signal transduction, and differentiation of human aortic smooth muscle cells (haSMCs) in vitro. Changes of cell proliferation following incubation with RAs in different doses (10-6 M, 10-7 M, and 10-8 M) were determined directly by proliferation kinetics and indirectly by bromodeoxyuridine enzyme-linked immuno sorbant assays and colony-formation assays. The migratory ability of haSMCs was examined with the help of migration assays.

Rationale And Objectives: The aim of the study was to examine the effects of azelastine on proliferation, clonogenic activity, cell-cycle, and migration of human aortic smooth-muscle cells (haSMCs) in vitro.

Methods: HaSMCs were treated for 4 days with azelastine (1 micromol/L, 25 micromol/L, 50 micromol/L). Half of the treated groups were incubated again with azelastine, the other half received azelastine-free medium every 4 days until day 20.

Purpose: The aim of the study was to examine the effects of flufenamic acid on proliferation, clonogenic activity, migratory ability, cell-cycle distribution, and p44/42-mitogen-activated protein kinase (MAPK) expression on serum-stimulated human aortic smooth muscle cells (haSMCs) in vitro.

Materials And Methods: HaSMCs were treated with flufenamic acid in three different doses (40 micromol/L, 200 micromol/L, 400 micromol/L) for 4 days, and then flufenamic-acid-free culture medium was supplemented every 4 days until day 20 after initial treatment. The growth kinetics were assessed.
