Dalvik virtual machine’s performance determines the performance of the Android platform. And each Dalvik virtual machine process is a Linux process, and each Dalvik virtual machine thread is a Linux thread. This paper analyses and researches process model of Android Dalvik virtual machine. Through research and analysis the role of Zygote in startup process of Dalvik virtual machine and the Zygo...

We carried out a prospective randomized trial on 220 couples with nontubal factor infertility to compare pregnancy rates and implantation rates after zygote intrafallopian transfer (ZIFT) and uterine embryo transfer (UET). The zygote was transferred by laparoscopy into the fallopian tube 24 hours after oocyst retrieval. UET was performed 72 hours after retrieval with abdominal sonography guide....

sheep (ovine) pulmonary adenocarcinoma (spa), also known as ovine pulmonary adneomatosis (opa),jaagsiekte and ovine pulmonary carcinoma (opc) is a contagious lung tumor in sheep and, more rarely, ingoats. this study was carried out in khuzestan, in the southwest of iran for a period of six months. a totalnumber of 3985 native breed goats were clinically inspected and postmortem examination was ...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

background: the aim of this study was to investigate the role of oxidative stress in the pathology of ovine dicrocoeliasis. methods : during dec 2013 - oct 2014, seventy-two sheep (1-3 years) with liver dicrocoeliasis along with 47 healthy sheep were selected from animals admitted for slaughtering at slaughterhouse located in neyshabour, razavi khorasan province, iran. results : in comparison t...

The primary structure of ovine hypothalamic hypophysiotropic luteinizing hormone-releasing factor, LRF, has been established as pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH(2) by hydrolysis of the peptide with chymotrypsin or pyrrolidone-carboxylylpeptidase and by analysis of the products by an Edman-dansylation sequencing technique, as well as by mass spectrometry of the derived phenylthiohydan...

Genetic diversity detected by analysis of amplified fragment length polymorphisms (AFLPs) of 54 Actinobacillus lignieresii isolates from different hosts and geographic localities is described. On the basis of variances in AFLP profiles, the strains were grouped in two major clusters; one comprising strains isolated from horses and infected wounds of humans bitten by horses and another consistin...

The CD154 (CD40 ligand) molecule is a member of the tumor necrosis factor (TNF) family and plays an important role in the interaction between antigen-specific lymphocytes and antigen-presenting cells. In this study, reverse transcription-PCR cloning was used to derive the sequence encoding ovine CD154. Sequence analysis of the cloned CD154 gene showed a similarity of 97%, 89%, and 88% with the ...

Ruminant lentiviruses share genomic sequences and biologic properties with human immunodeficiency viruses. Four ovine lentivirus strains were assessed for cytopathic effects and virus replication. Lentivirus isolate H/24 produced high virus titers and lysis of synovial cells but replicated slowly and caused no fusion of alveolar macrophages. Lentivirus isolates 84/28 and 85/14 produced low viru...

Control of growth and differentiation during mammalian embryogenesis may be regulated by growth factors. With the use of a very sensitive method, the reverse transcription-polymerase chain reaction, expression of some growth factor transcripts was examined during ovine peri-implantation development. Transcripts for transforming growth factor-alpha (TGF-alpha) were found in day 15 to day 30 conc...
