Background & Aim:Vaginal disease has always been a great concern of women. Medicinal plants as natural resources with fewer side effects can effectively treat these infections given the diversity of these infections, resistance to antibiotics and side effects of existing drugs. The present study aimed to compare antimicrobial effects of methanol extract of Francoeuria Undul...

1 Fresh data on English grain yields 1268-1480 are combined with revised price series to measure the frequency and scale of serious harvest shortfalls and estimate the elasticity of demand for cereals. Major food availability declines are shown to have been a significant component of most historical subsistence crises, as back-to-back shortfalls were of the worst famines. Although farmers did a...

post-harvest management of potatoes is a major challenge in iran. approximately 30% of the harvest is lostafter a few months of storage. the chemical methods for long term storage are not adequate to controldeterioration and also produce undesirable side effects. to address this issue, a study on radiationpreservation of potatoes was carried out. agria potato bulbs were irradiated using beta be...

Flow cytometry is a powerful tool capable of simultaneously analyzing multiple parameters on a cell-by-cell basis. Lung tissue preparation for flow cytometry requires creation of a single-cell suspension, which often employs enzymatic and mechanical dissociation techniques. These practices may damage cells and cause cell death that is unrelated to the experimental conditions under study. We tes...

Prompt tillage after crop harvest was investigated as a cultural control for the tobacco cyst nematode, Globodera tabacum tabacum, on stalk-cut broadleaf cigar wrapper tobacco. Stalk stumps and roots remaining after harvest were destroyed by tilling immediately or from 2 to 6 wk after harvest in field experiments over 4 yr. Cyst nematode Pf/Pi ratios ranged from 0.65 to 1.62 when plants were ti...

We present the idea of using potential infringements on annual allowable harvest targets as an approach to estimate threats from invasive species to the forest products sector. The approach uses present-day harvest levels as a reference level to estimate when and where the impact of a nonnative forest pest could become economically damaging. We use a generic model that simulates spread and dama...

Life history traits of wild animals can be strongly influenced, both phenotypically and evolutionarily, by hunting and fishing. However, few studies have quantified fishery selection over long time periods. We used 57 years of catch and escapement data to document the magnitude of and trends in gillnet selection on age and size at maturity of a commercially and biologically important sockeye sa...

Variable retention harvest promotes biodiversity conservation in managed boreal forests by ensuring forest continuity and structural complexity. However, do post-harvest and post-fire patches maintain the same structural complexity? This study compares post-harvest and post-fire residual patches and proposes retention modalities that can maintain the same structural complexity as in natural for...

Forest harvesting is an important, ongoing disturbance that affects the composition, structure, and ecological function of the majority of the world’s forests. However, few studies have examined the interaction between land-use conversion and harvesting. We utilize a unique, spatially explicit database of all cutting events (n > 13,000) and land-cover conversions for Massachusetts over the past...

BACKGROUND The tunnelling as opposed to the open harvest technique for harvesting long saphenous vein for coronary artery bypass procedures is a less frequently used technique as it requires more handling of the vein and this may induce trauma. This study aims to compare the degree of endothelial denudation and donor site morbidity between the two different harvest techniques. METHODS Sapheno...
