background: hypertension (htn) is the most commonly encountered systemic disease in general population. nutrient canals contain blood vessels and nerves that mostly appear in the anterior mandibular region. nutrient canals are not detected in radiographs of all patients, and their normalcy is controversial by many investigators. objectives: the present study investigated the correlation between...

Because ocean water is typically resource-poor, bacteria may gain significant growth advantages if they can exploit the ephemeral nutrient patches originating from numerous, small sources. Although this interaction has been proposed to enhance biogeochemical transformation rates in the ocean, it remains questionable whether bacteria are able to efficiently use patches before physical mechanisms...

Salinity is one of the greatest environmental challenges facing plant growth and development in the 21st century. Salicylic acid (SA) is a phenolic compound and signal molecule involved in the regulation of plants responses to biotic and abiotic stresses. This greenhouse experiment was conducted to determine effects of SA application on Kentucky bluegrass (Poa pratensis L.) responses to salinit...

zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...

Mining the data from large-plain text enhances the retrieval of information from resources. This paper describes about the automatic discovery of part-whole patterns from the texts using knowledge. The Parts are found by learning semantic constraints and linking documents to the knowledge-base. Knowledge Discovery in text is a potential method, which automatically extracts the concepts and conc...

phosphorus (p) is a macro mineral in broiler nutrition. in growing broilers, besides its requirement for proper bone development, it is also involved in almost all metabolic processes. poor p availability results in decreased productivity and poor health status.phosphorus availability from plant derived feeds is affected by an anti-nutritional factor “phytate”, which forms a variety of insolubl...

1. Nutrient diffusing substrata were used to determine the effect of added inorganic nitrogen (N) and phosphorus (P) on the development of epilithic and epixylic biofilms in 10 North American streams. Four treatments of diffusing substrata were used: Control (agar only), N addition (0.5 M NaNO3), P addition (0.5 M KH2PO4), and N + P combined (0.5 M NaNO3 + 0.5 M KH2PO4). Agar surfaces were cove...

  Humans suffer transient or persistent starvation due to a lack of food intake, either because of fasting, voluntary dieting, or due to the scarcity of available food. At the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. Blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of en...

Prymnesium parvum is a globally distributed prymnesiophyte alga commonly found in brackish water marine ecosystems and lakes. It possesses a suite of toxins with ichthyotoxic, cytotoxic and hemolytic effects which, along with its mixotrophic nutritional capabilities, allows it to form massive Ecosystem Disruptive Algal Blooms (EDABs). While blooms of high abundance coincide with high levels of ...
