The popularity of XML results in producing large numbers of XML documents. Therefore, to develop an approach of association rule mining on native XML databases is an important research. The FP-growth based on an FP-tree algorithm performs more efficiently than other methods of association rules mining, but it cannot be applied to native XML databases. Hence, we adaptive an improving FPtree algo...

Fish oil (FO) has been shown to have anti-inflammatory properties in animal models of inflammatory bowel disease, but how fish peptides (FP) influence intestinal inflammation has been less studied. Male Wistar rats, divided into five groups, were included in a 4-week dietary intervention study. Of the groups, four were exposed in the fourth week to 5 % dextran sulfate sodium (DSS) to induce col...

The associations between inhaled corticosteroid (ICS) use and pulmonary infections remains controversial. Chlamydia pneumoniae (C. pneumoniae) accounts for asthma exacerbations; however, there are no data regarding ICS effects on C. infections. Thus, we investigated whether fluticasone propionate (FP) or budesonide (BUD) could affect infection in vitro vivo, focusing the possible mechanisms tha...

BACKGROUND Treatment of fetal pancreas (FP) isografts with insulin-like growth factor-I greatly improves the rate of conversion to euglycemia in diabetic rats. Complete knowledge of other factors that may facilitate the engraftment and function of FP in vivo is still embryonic. Augmenter of liver regeneration (ALR) is a newly described polypeptide growth factor found in weanling rat livers. ALR...

Fibroblast growth factors (FGFs) have been implicated in multiple aspects of cancer development and growth for over 20 years [1]. Research has shown that FGFs have a role in a) directly promoting cancer cell growth, b) tumor angiogenesis, and c) more speculatively, the survival of a group of cancer cells called “tumor stem cells” that are particularly difficult to target with current therapies....

BACKGROUND Fibroblast growth factors (FGFs) play important roles in multiple cancers by supporting tumor growth and angiogenesis. FP-1039 (GSK3052230) is a FGF ligand trap consisting of the extracellular domain of FGF receptor 1 (FGFR1) fused with the Fc region of IgG1. FP-1039 binds and neutralizes multiple FGFs that normally bind FGFR1. The primary objective of this phase I study was to evalu...

Association Rule is an important tool for today data mining technique. But this work only concern with positive rule generation till now. This paper gives study for generating negative and positive rule generation as demand of modern data mining techniques requirements. Here also gives detail of “A method for generating all positive and negative Association Rules” (PNAR). PNAR help to generates...

کاوش قوانین وابستگی یک تکنیک مهم در داده کاوی است که در آن یافتن الگوهای تکراری، یک مرحله بسیار زمان بر و پر هزینه به شمار می رود. در این تحقیق یک روش جدید برای یافتن الگوهای تکراری بر روی داده هایی که مقادیر آن ها به شکل نوسانی (افزایش، کاهش یا بدون تغییر) هستند مانند داده های تغییرات قیمت سهام در بورس اوراق بهادار ارائه می شود. در این روش، فقط تعداد کمی از تکرار مجموعه عناصر از پایگاه داده جس...

Association rule mining has attracted wide attention in both research and application area recently. Mining multilevel association rules is one of the most important branch of it. This paper introduces an improved apriori algorithm so called FP-growth algorithm that will help resolve two neck-bottle problems of traditional apriori algorithm and has more efficiency than original one. New FP tree...
