BACKGROUND The first changes associated with smoking are in the small airway epithelium (SAE). Given that smoking alters SAE gene expression, but only a fraction of smokers develop chronic obstructive pulmonary disease (COPD), we hypothesized that assessment of SAE genome-wide gene expression would permit biologic phenotyping of the smoking response, and that a subset of healthy smokers would h...

The intensity of asthma exacerbations may vary from mild to severe. Many studies have demonstrated that the speed at which severe asthma exacerbation (SAE) develops varies among patients. In some asthmatics, the exacerbation comes on very quickly, whereas in others there is a progressive deterioration of clinical, functional and blood gas parameters. Sudden SAE are characterised by their explos...

objective(s): gastric cancer is the first and second leading cause of cancer related death in iranian men and women, respectively. gastric cancer management is based on the surgery, radiotherapy and chemotherapy. in the present study, for the first time, the beneficial effect of saffron (crocus sativus l.) aqueous extract (sae) on the 1-methyl-3-nitro-1-nitrosoguanidine (mnng)-induced gastric c...

A new reverse transcriptase (RT) inhibitor was extracted and purified from the red alga Schizymenia pacifica. The chromatographic behavior and chemical properties of this sea algal extract (SAE) suggest that it is a sulfated polysaccharide having a molecular weight of approximately 2,000,000. SAE is composed of galactose (73%), sulfonate (20%), and 3,6-anhydrogalactose (0.65%). SAE is a member ...

This paper presents an architecture called PeSoV using new emerging technologies to increase the security, reliability and connectivity of motorized vehicles. Many people die because of car accidents caused by lack of attention and imprudence of car drivers. Some technologies like the standard IEEE 1609, Zigbee and a network of ranging sensors can be used as tools to help the driver to avoid ac...

Agricultural educators are confronted with a dilemma. They continue to espouse a theory of learning that requires Supervised Agricultural Experience (SAE) but their students practice fewer and fewer SAEs. The various dimensions of the theory-to-practice dilemma have not been adequately addressed by agricultural educators. Researchers have recommended changes in either espoused theories or theor...

Alguns componentes mecânicos de sistemas usados em usinas açúcar e etanol, especialmente aqueles que atuam no setor preparação extração do caldo, são sujeitos a desgaste severo. Engrenagens transmissão potência exemplos destes exigem periodicamente manutenções, neste caso, podem ser executadas por meio deposição solda na região dentado. Neste trabalho buscou-se encontrar o aço ideal para fabric...

This study investigates the deposition of hydrogenated diamond-like carbon (DLC) films on SAE 1045 alloy samples using a plasma-enhanced chemical vapor (PECVD) system and evaluates their potential as automotive coatings. Copper doping was performed via hollow copper cathode to examine its effects DLC films. The primary focus determine structural properties, color variations, friction resistance...

Refractory ascites (RA) is a challenging complication after orthotopic liver transplantation. Its treatment consists of the removal of the precipitating factors. When the etiology is unknown, supportive treatment can be attempted. In severe cases, transjugular intrahepatic portosystemic shunts, portocaval shunts, and liver retransplantation have been used with marginal results. Recently, spleni...
