We studied the treatment of multiple rib fractures in NIC, comparing ventilatory with nonventilatory methods in 69 patients who were randomly allocated to one of the following two treatments: (1) a CPAP mask combined with regional analgesia (n = 36); or (2) endotracheal intubation and mechanical ventilation with PEEP (n = 33). Clinical outcome was as follows: mean duration of treatment, 4.5 +/-...

to study  the effect of powdery mildew on sugar beet yield and percentage of sugar losses sugar percent losses, ten genotypes were compared in a factorial  experiment based on  randomized complete block design with 3 replications and two factors. the first factor was spraying treatment with two levels and the second were genotypes. inoculation was carried out using the pathogens' conidial ...

erosion and sediment movement phenomena are one of the most complex issues in management of rivers drainage areas that in water projects are very important. that its measurement wants high time and cost. issue of surface runoff in river basin is a complex issue that human knowledge and understanding about its physical laws a viewpoint of some mathematical formulas is limited. in this study to i...

Pneumocystis carinii pneumonia (PCP) causing acute respiratory failure (ARF) in patients with acquired immunodeficiency syndrome (AIDS) has been reported in several studies to have a mortality of 84 to 100 percent. A recent report found a 42 percent survival rate. We followed 58 patients with AIDS who required positive pressure ventilation and identified 33 patients with PCP and ARF who had a P...

This report presents the results of an evidence-based approach to obtaining the best available information on the natural history, prevalence, incidence, diagnosis, and treatment of root caries. Searches of electronic databases produced 807 references; from these and from citations in the selected articles, a final 161 references were used. We found that the information on the natural history o...

OBJECTIVES Multiple systematic reviews have evaluated fluorides for caries prevention in children, but a need to review the literature regarding supplemental fluoride use in adults still remains. The purpose of this systematic review is to evaluate the research regarding professional and/or supplemental self-applied fluoride for preventing and remineralizing caries in moderate and high caries r...

this study was performed for evaluation of the qualitative traits of safflower (carthamus tinctorius l.) as affected by azotobacter and mycorrhizal symbiosis (host plant root symbiosis with the glomus fungi) as factorial experiment based on randomized complete block design with three replications in research farm of college of arak islamic azad university during growing season of 2011-2012. tre...

Bahia grass (Paspalum notatum) and industrial sweet potato (Ipomoea batatas) colonized by Glomus deserticola, G. etunicatum, and G. intraradices were grown in aeroponic cultures. After 12 to 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulation was detected intra-and extraradical...
