Abstract
Cisplatin (cis-diamminedichloroplatinum (II), DDP) is an antineoplastic agent widely used in the treatment of solid tumors because of its extensive cytotoxic activity. However, the main limiting side effect of DDP use is nephrotoxicity, a rapid deterioration in kidney function due to toxic chemicals. Several studies have shown that epigenetic processes are involved in DDP-induced nephrotoxicity. Noncoding RNAs (ncRNAs), a class of epigenetic processes, are molecules that regulate gene expression under physiological and pathological conditions. MicroRNAs (miRNAs) are the most characterized class of ncRNAs and are engaged in many cellular processes. In this review, we describe how different miRNAs regulate some pathways leading to cell death by apoptosis, specifically the intrinsic apoptosis pathway. Accordingly, many classes of natural products have been tested for their ability to prevent DDP-induced apoptosis. The study of epigenetic regulation for underlying cell death is still being studied, which will allow new strategies for the diagnosis and therapy of this unwanted disease, which is presented as a side effect of antineoplastic treatment.

Abstract
We have studied 175 consecutive asthmatic patients presenting with: 1) a reversible airflow obstruction, demonstrated by an increase in the forced expiratory volume in 1 second (FEV1) or in the forced vital capacity (FVC) by at least 12% along with an absolute increase of 200 ml versus prebronchodilator values after inhalation of salbutamol; 2) FVC below the lower normal limit before administration of the bronchodilator; and 3) normal FVC or slow vital capacity after bronchodilator. Two different criteria for the lower normal limit of the FEV1/FVC ratio were used to determine whether prebronchodilator spirometric patterns could be considered obstructive or not. The use of the predicted FEV1/FVC ratio as the lower normal limit allowed correct identification of obstruction in 94.9% of the patients, whereas taking the estimated fifth percentile as the lower normal limit of the FEV1/FVC correctly identified obstruction in only 78.9% of the asthmatics. Our results suggest that the predicted FEV1/FVC ratio is an adequate estimate of the lower normal limit in asthmatic patients with reduced FVC in order to distinguish obstructive from nonobstructive patterns.
