oil prices may be having a direct and indirect effect through the exchange rate on the price of agricultural commodities. in this paper, the impact of world oil prices and exchange rate shocks on prices of specific agricultural commodities including wheat, corn, soybeans and sunflowers in iran is discussed. for this purpose, vector autoregressive model with monthly data over the period 2010-199...

BACKGROUND Some studies suggest smoking may result in poorer clinical outcomes in head and neck cancer, but the evidence is heterogeneous and some of it is poor quality. In a large, population-based, study we investigated: (i) whether smoking at diagnosis is an independent prognostic factor for cancer-specific survival in head and neck cancer; and (ii) whether the association varies by site and...

The Drosophila hsroJ locus produces one of the largest and most active heat shock puffs, yet it does not encode a heat shock protein. Instead, this locus produces a distinctive set of three transcripts, all from the same start site. The largest transcript, c01, is limited to the nucleus and appears to have a role there. A second nuclear transcript, o~2, is produced by alternative termination an...

OBJECTIVE To examine associations between cardiovascular system medication use with cognition function and diagnosis of dementia in older adults living in nursing homes in Australia. METHODS As part of a cross-sectional study of 17 Australian nursing homes examining quality of life and resource use, we examined the association between cognitive impairment and cardiovascular medication use (id...

where the equations a0x+ b0y + c0 = 0 and a1x+ b1y + c1 = 0 define any two distinct lines. It is known that any conic section can be “generated by the intersection of corresponding lines of two related pencils in a plane” [Som51], p.388. In other words, given two distinct pencils, (a00x+b00y+c00)(1−t)+(a10x+b10y+c10)t = 0 and (a01x+b01y+c01)(1−t)+(a11x+b11y+c11)t = 0, to each value of t corresp...

Acquired resistance (AQR) to drug treatment occurs frequently in cancer patients and remains an impediment to successful therapy. The aim of this study was to gain insight into how AQR arises following the application of PI3K/mTOR inhibitors. H1975 lung cancer cells with EGFR T790M mutations that confer resistance to EGFR inhibitors underwent prolonged treatment with the PI3K/mTOR inhibitor, BE...

BACKGROUND Data on the economic burden of head and neck cancers (HNCs) in Germany is scarce. About 16%-28% of these cancers are associated with human papillomavirus (HPV) infection. Therefore, the study reported here aimed to assess the annual costs of HPV-related HNCs incurred by hospitalization, inpatient rehabilitation, and sick leave in Germany in 2008. METHODS A cross-sectional retrospec...

Key message "We identified both quantitative and quantitative resistance loci to Leptosphaeria maculans, a fungal pathogen, causing blackleg disease in canola. Several genome-wide significant associations were detected at known and new loci for blackleg resistance. We further validated statistically significant associations in four genetic mapping populations, demonstrating that GWAS marker loc...
