Cys proteinases play important roles in plant cell development and senescence. A cDNA, AsNODf32, obtained by differential screening of a nodule cDNA library of the leguminous plant Chinese milk vetch (Astragalus sinicus), represents a nodule-specific Cys proteinase similar to that reported for the actinorhizal Alnus glutinosa-Flankia symbiosis. A characteristic feature of this proteinase is the...

Résumé Les lésions hépatiques nodulaires sont majoritairement tumorales. Le nodule nécrotique solitire du foie est rare. Le diagnostic preopératoire est difficile. Il s'agit d'une femme âgée de 43 ans qui était opérée d'un adénocarcinome du rectum métastatique au foie opéré.Le scanner abdominal de surveillance a révélé un nodule hépatique d'allure métastatique. Le second cas est celui d'un homm...

Melphalan (L-phenylalanine mustard), a cytostatic drug used in treatment of human breast cancer, was injected into mice bearing preneoplastic hyperplastic alveolar nodule mammary outgrowth line D2. Melphalan, doses of either 2.5 or 5.0 mg/kg, markedly enhanced tumor formation in its mammary nodule outgrowth line. Samples of nodule outgrowths in untreated mice produced 13% tumors by 9 months aft...

Background: In order to determine the prognosis of neonates, it is recommended to use umbilical gas analysis in all high-risk pregnancies. However, utilizing umbilical gas analysis and Apgar score together is very helpful for determining the mortality rate confidence interval. Therefore, in this study, we investigated the application of umbilical gas analysis in assessing the prognosis of infan...

In this paper, a complete system for automatic lung nodule detection from Chest CT data is proposed. The proposed system includes the methods of lung segmentation and nodule detection from CT data. The algorithm for lung segmentation consists of surrounding air voxel removal, body fat/tissue identification, trachea detection, and pulmonary vessels segmentation. The nodule detection algorithm co...

background: abnormal umbilical cord ph can be indicated a distress imposed of newborn and can also be useful in determining the prognosis of the newborn. there are different views about the effect of the neonatal delivery method on the blood gas analysis of the umbilical artery. this study aimed to determine the effect of the method of delivery on umbilical artery ph. methods: in this cross –se...

We compared nodule initiation in lateral roots of Pisum sativum (L.) cv Sparkle and in a low-nodulating mutant E2 (sym 5). In Sparkle, about 25% of the infections terminated in the epidermis, a similar number stopped in the cortex, and 50% resulted in the formation of a nodule meristem or an emerged nodule. The mutant E2 (sym 5) was infected as often as was the parent, and it formed a normal in...

A 49-year-old female presented with an aggressive pelvic angiomyxoma (AAM). The completely resected specimen revealed the usual myxedematous tumor with a nodule inside it. Histopathologically, the myxedematous area consisted of bland spindle-shaped cells in the background of blood vessels of varying calibers, and the nodule was composed of tumor cells with epithelioid features. In the nodule, c...

PVA roller brushes are widely used for cleaning after the CMP process, one of semiconductor manufacturing processes. The brush features protrusions called nodules and rotates on wafer in cleaning. This article introduces a model that uses to remove nanoscale impurities. evanescent fields prism enable us observe contact behavior clarify there is little volume near surface during sliding. We clas...
