Determination of field capacity in the Chibunga and Guano rivers micro-basins.

The micro-basins of the Chibunga and Guano rivers are located within the sub-basin of the Chambo River, which starts at the thaw of the Chimborazo, crosses the cities of Guano and Riobamba, and ends in the Chambo River. These rivers are considered fluvial hydrological forces and geological limits of the aquifer, located in this sub-basin. For this reason, our investigation addressed the field capacity in the micro-basins of Chibunga and Guano rivers, to determine the maximum retention potential, i.

Deregulated MicroRNAs in Cancer-Associated Fibroblasts from Front Tumor Tissues of Lung Adenocarcinoma as Potential Predictors of Tumor Promotion.

Cancer-associated fibroblasts (CAFs) are the main component of the tumor stroma and promote tumor progression through several mechanisms. Recent evidence indicates that small noncoding RNAs, microRNAs (miRNAs), play key roles in CAF tumor-promoting properties; however, the role of miRNAs in lung cancer-associated fibroblasts remains poorly defined. We characterized the differential miRNA expression profile of fibroblasts isolated from matched tumor front (F-CAFs), inner tumor (In-CAFs), and normal adjacent (NFs) tissues from four lung adenocarcinoma patients (ADs) using microarray analysis.

Analysis of microRNA expression signatures in malignant pleural mesothelioma, pleural inflammation, and atypical mesothelial hyperplasia reveals common predictive tumorigenesis-related targets.

Pleural chronic inflammation (PP) and mesothelial hyperplasia (HP) may be critical to the development of malignant pleural mesothelioma (MPM). Nonetheless, studies searching for mechanistic links involving microRNA (miRNA) regulation among these interrelated processes have not been reported. Using PCR-Array, we identified the miRNAs expressed in pleural tissues diagnosed with MPM (n=5), PP (n=4) and HP (n=5), as well as in non-cancerous/non-inflammatory tissue as the normal control (n=5).

The immediate response to severe shock in a canine model with a combination of hypertonic-hyperoncotic solution with naloxone.

To evaluate the acute hemodynamic and acid-base balance effects of hypertonic-hyperoncotic solution (HHS) combined with naloxone in the treatment of hemorrhagic shock in 45 male splenectomized adult mongrel dogs, a severe controlled hemorrhagic shock (20 mmHg mean arterial pressure during 30 min) was established in the groups (n=6) no treatment, shed blood reinfusion, hypertonic-hyperoncotic (saline-dextran) solution alone, naloxone alone (NX), or combination. Interventions included propiopromazine-pentobarbital anesthesia and installation of Swan-Ganz, femoral arterial, and urethral catheters, and exsanguination at 20 mmHg mean arterial pressure during 30 min followed by treatment and observation for 160 min. Fifteen (33%) dogs died before completing the 30-min shock period.
