Quality Growth Index (QGI) is affected by two sets of combined-structural and social indicators. Structural indicator contributes to achieve the main target of sound-sustainable-competitive output growth. By the way, the sound output growth should enhance social-public services and living standards. Although QGIs are weightedly computed based on different scenarios, the trend of the QGIs and co...
پنیر یکی از فراورده های تخمیری شیر می باشد که به عنوان یکی از منابع غنی تامین پروتئین، چربی و مواد معدنی مورد نیاز بدن محسوب می شود. مطالعه حاضر به منظور ارزیابی شاخص بهداشتی پنیرهای صنعتی و سنتی سطح شهرستان مشهد، از طریق شمارش کلی فرم ها و جستجوی اشریشیاکلی و همچنین بررسی میزان آلودگی این پنیرها به گروه های سرمی پاتوزن اشریشیاکلی می باشد. در این بررسی که از مهر ماه لغایت اسفند ماه سال 1388 به...
I n 2007, CALVERLEY et al. [1] reported the results of the TORCH (Towards a Revolution in Chronic Obstructive Pulmonary Disease Health) study, which showed that combination of salmeterol (a long-acting b-agonist (LABA)) plus fluticasone propionate (an inhaled corticosteroid (ICS)) had a trend toward a lower all-cause mortality rate in patients with chronic obstructive pulmonary disease (COPD) c...
Shiga-toxin-producing Escherichia coli (STEC) O157:H7 is a recently emerged zoonotic pathogen with considerable morbidity. Since the emergence of this serotype in the 1980s, research has focussed on unravelling the evolutionary events from the E. coli O55:H7 ancestor to the contemporaneous globally dispersed strains observed today. In this study, the genomes of over 1000 isolates from both huma...
The release of neutrophil extracellular traps (NETs), either during "suicidal" or "vital" NETosis, represents an important strategy of neutrophils to combat Gram-negative bacteria. Lipopolysaccharide (LPS), a major component of the outer membrane of Gram-negative bacteria, is a reported stimulus for NET formation. Although it is widely acknowledged that the structural diversity in LPS structure...
This study introduces the respiratory exchange ratio (RER; the ratio of whole-body CO2 production to O2 consumption) as an aid to monitor metabolic acidosis during the early phase of endotoxic shock in unanesthetized, freely moving rats. Two serotypes of lipopolysaccharide (lipopolysaccharide [LPS] O55:B5 and O127:B8) were tested at shock-inducing doses (0.5-2 mg/kg). Phasic rises in RER were o...
The role of serum factors such as lipopolysaccharide (LPS)-binding protein (LBP) and of macrophage-expressed CD14 and beta2 integrins in the activation of bovine macrophages by LPS was investigated. Macrophage activation was determined by measuring tumor necrosis factor production, NO generation, and upregulation of procoagulant activity by LPS (Escherichia coli O55:B5) at concentrations of 100...
This paper investigates the impact of dams on infant mortality using 32 waves of DHS data that have GPS locations of households. This allows us to estimate the impact of dams on households that reside upstream, downstream, and within its immediate vicinity. We use a sample of over 400,000 children in 17 countries in Africa. In contrast to earlier research on the impact of dams on agricultural p...
A previously characterized O157-specific lytic bacteriophage KH1 and a newly isolated phage designated SH1 were tested, alone or in combination, for reducing intestinal Escherichia coli O157:H7 in animals. Oral treatment with phage KH1 did not reduce the intestinal E. coli O157:H7 in sheep. Phage SH1 formed clear and relatively larger plaques on lawns of all 12 E. coli O157:H7 isolates tested a...
