Motivation: The rice white tip nematode (RWTN) Aphelenchoides besseyi is a migratory plant parasitic nematode that infects the aboveground parts of plants. Fatty acid- and retinoid-binding (FAR) proteins are nematode-specific proteins that are involved in many important biological processes. Genes encoding FAR proteins have been identified in many species of nematodes, which indicated that nematodes may produce more than one type of FAR protein. The main goal of this study is to find new molecular targets including new far genes that will help control RWTN, and reduce the economic damage caused by RWTN.
Results: Two RWTN populations with different levels of pathogenicity and reproduction were sequenced and analyzed with next-generation sequencing. 17 087 transcripts were annotated using six databases and 1696 differentially expressed genes (DEGs) were identified between the two RWTN populations. Seven new Ab-far genes were identified from the transcriptome data of the two RWTN populations which is the first to identify multiple far genes in plant parasitic nematodes. This study is the first to identify far genes in the nervous system of nematodes and the first to report a transcriptome sequencing analysis of different RWTN populations. The results help elucidate the genes related to parasitism and pathogenicity and also contribute to the identification of new target genes and development of new methods to control RWTN.

Distributed widely across the rice growing regions of India, the rice leaf and bud nematode ( Christie 1942) can cause substantial yield loss in rice. Whitening of leaf tips is the characteristics damage symptom of this nematode and therefore it is popularly referred to as the rice white tip nematode (RWTN). While information on the damage severity of RWTN is available from others parts of the country, to date, no information is available from the state of Jharkhand.

The rice white tip nematode (RWTN), Aphelenchoides besseyi and the chrysanthemum foliar nematode (CFN), Aphelenchoides ritzemabosi are migratory plant parasitic nematodes that infect the aboveground parts of plants. In this research, Arabidopsis thaliana was infected by RWTN and CFN under indoor aseptic cultivation, and the nematodes caused recognizable symptoms in the leaves. Furthermore, RWTN and CFN completed their life cycles and proliferated.

Background: It has been recognized that "cross-talk" occurs between coronary flow and left ventricular (LV) function. This study tested the hypothesis that impairment of coronary flow reserve (CFR) in arterial hypertension is associated with LV systolic and diastolic dysfunction, independent of abnormalities in LV geometry.
Methods: We studied 59 newly diagnosed, never-treated hypertensive patients, using transthoracic Doppler echocardiography including pulsed Tissue Doppler of mitral annulus and CFR on left anterior descending artery (low-dose dipyridamole).
