B rownfield sites are a common eyesore on the edges of many cities; the abandoned, decaying hulks of industrial or commercial structures sit rusting and forgotten while they leach harmful chemicals such as asbestos, solvents or heavy metals into the soil. Some brownfields lie virtually untouched for years because it is often cheaper to expand cities into virgin territory than to demolish large ...
Methaemoglobinaemia may be caused by ingestion of a number of drugs, among them nitrites, some of which are remarkably toxic. This was tragically highlighted by the death of a 17 year old dental nurse after taking a single 1 g tablet of sodium nitrite. These tablets are widely used in the medical and dental profession to prevent rusting of instruments while immersed in disinfectant solutions. T...
Quantitative adult plant resistance (APR) to stem rust (Puccinia graminis f. sp. tritici) is an important breeding target in wheat (Triticum aestivum L.) and a potential target for genomic selection (GS). To evaluate the relative importance of known APR loci in applying GS, we characterized a set of CIMMYT germplasm at important APR loci and on a genome-wide profile using genotyping-by-sequenci...
بیماری زنگ زرد گندم با عاملPuccinia striiformis Westend. f. sp. tritici ، یکی از خسارتزاترین بیماریهایگندم در ایران به شمار میرود. مقاومت میزبانی به ویژه مقاومت غیر اختصاص–نژادی (Race- nonspecific)، اقتصادیترین روش مدیریت زنگ زرد است. اگرچه طول عمر ژنهای مقاومت اختصاص– نژادی(Race-specific) با ترکیب ژنهای مقاومت موثر میتواند طولانی شود. روش جایگزین، بهکارگیری ارقامی است که دارای مقاومت غ...
Background. BDNF and NT-4/5 have been proposed to be involved in the coordinated adaptations of the neuromuscular system to the elevated level of activity, but an activity-dependent expression of neurotrophins in skeletal muscle is not well established. Objectives. We, therefore, investigated the effect of one session of resistance exercise on mRNA expression of some neurotrophins in Slow and ...
Dormant or slow-cycling disseminated tumor cells (DTCs) in bone marrow (BM) are resistant to conventional therapy in various cancers including head and neck squamous cell carcinoma (HNSCC), although the molecular mechanisms remain largely unknown. This study aimed to identify the intrinsic molecular mechanisms underlying drug resistance in BM-DTCs. We used in vivo selection of the human HNSCC c...
Tumor recurrence after chemotherapy is a major cause of patient morbidity and mortality. Recurrences are thought to be due to small subsets of stem-like cancer cells that are able to survive chemotherapy and drive tumor re-growth. A more complete understanding of stem-like cancer cell regulation is required to develop therapies to better target and eliminate these cells. Slow-cycling stem cells...
Turning operations using single-point cutting tools have been one of the earliest and most used methods for metal. It has widely studied forces workpiece surface roughness to affect turning operations. When metal, tool needs be tougher than so it can resist high temperatures wear while operation is conducted. The mechanical qualities martensitic stainless steel (MSS) grade Custom-450 significan...
