The Dof (DNA binding with One Finger) family of single zinc finger proteins is a family of plant-specific transcription factors. These transcription factors have a variety of important functions in different biological processes in plants. In the current study, we identified 26 Dof family genes in moso bamboo (Phyllostachys heterocycla var. pubescens). A complete overview of PhDof genes in moso bamboo is presented, including the gene structures, phylogeny, protein motifs and expression patterns. Phylogenetic analysis of the 26 PhDof proteins identified four classes constituting seven clusters (A, B1, C1, C2, D1, D2 and D3). In addition, a comparative analysis between the Dof genes in moso bamboo, Arabidopsis (Arabidopsis thaliana L.) and rice (Oryza sativa L.) was also performed, and several putative paralogous and orthologous genes were identified. The exon numbers in Dof genes ranged from one to three in many plants; however, the exon number in PhDofs ranged from one to four. The PhDof genes displayed differential expression in different parts of the shoot and at different flower development stages. This study represents the first step towards a genome-wide analysis of the Dof genes in moso bamboo. Our study provides a useful reference for cloning and functional analysis of members of the Dof gene family in moso bamboo and other species.
Congenital Acute Megakaryoblastic Leukemia in a Neonate with Antenatal Hepatosplenomegaly
( Tao Cheng Lu ),( Jae Wook Lee ),( Sook Kyung Yum ) 대한주산의학회 2021 Perinatology Vol.32 No.1
Various conditions can lead to antenatal hepatosplenomegaly. In addition to commonly known etiologies like hydrops fetalis or viral illnesses, hematologic disorders like congenital leukemia, although rare, should also be ruled out. We present a case of hepatosplenomegaly detected during antenatal screening in a neonate, in whom acute megakaryoblastic leukemia was diagnosed postnatally based on the immunophenotype.
Research on Torque Ripple Suppression of Position Sensorless Brushless DC Motor during Commutation
Yang Tao,Li Quan-feng,Wang Shi-tao,Lu Zheng-yu 전력전자학회 2011 ICPE(ISPE)논문집 Vol.2011 No.5
Position sensorless PM brushless DC motor generates pilsating current in the course of nature commutation, which causes torque ripple. In order to reduce the torque ripple, the current during commutation is controlled by certain methods which need current sensors usually. This paper proposed a novel and low cost method which can reduce torque ripple by changing the duty cycle during comutation. Experimental results show that this method is easily used to reduce the pulsating current and torque ripple during comutation without current sensors.

Piwi proteins and Piwi-interacting RNAs (piRNAs) have been implicated in transposon control in germline from Drosophila to mammals. To examine the profile of small RNA expression in human cancer cells and explore difference in small RNA transcriptome, small RNA libraries prepared from wildtype, HILI overexpressed and HILI knockdowned Hela cells were sequenced using Solexa technology. piRNAs and other repeat- associated small RNAs were observed in Hela cells. By using in situ hybridization, piR-49322 was localized in the nucleolus and around the periphery of nuclear membrane in Hela cells. Following the overexpression of HILI, the retrotransposon elements LINE1 was significantly repressed, while LINE1-associated small RNAs decreased in abundance. The present study demonstrated that HILI along with piRNAs plays a role in LINE1 suppression in Hela cancer cell line. [BMB reports 2010; 43(9): 635-641]
