This paper investigates the routing problem for information leakage reduction in multi-channel ad-hoc networks. In particular, we focus on two routing models: Trusted Group Multicast (TGM) and Confidential Unicast (CU). In TGM, a group member shares the information with all other group members; while in CU, a group member may only want to share the information with a few selected group members....

Transcription by RNA polymerase II is antagonized by the presence of a nearby tRNA gene in Saccharomyces cerevisiae. To test hypotheses concerning the mechanism of this tRNA gene-mediated (tgm) silencing, the effects of specific gene deletions were determined. The results show that the mechanism of silencing near tRNA genes is fundamentally different from other forms of transcriptional silencin...

Introduction: The aim of present study was to investigate the effects of royal jelly (RJ) on the number of Nissl-stained neurons in caudate putamen unit (CPU) and substantia nigra pars compacta (SNC) and the thickness of gray (TGm) and white matter (TWm) of cerebral and cerebellar cortex in male rats with Parkinson’s disease (PD). Methods: Seventy five Sprague-Dawley adults’ male ra...

Stimulation of the local renin-angiotensin system and apoptosis characterize the diabetic heart. Because IGF-1 reduces angiotensin (Ang) II and apoptosis, we tested whether streptozotocin-induced diabetic cardiomyopathy was attenuated in IGF-1 transgenic mice (TGM). Diabetes progressively depressed ventricular performance in wild-type mice (WTM) but had no hemodynamic effect on TGM. Myocyte apo...

Abnormal methylation at the maternally inherited H19 imprinted control region (H19 ICR) is one of the causative alterations leading to pathogenesis of Beckwith-Wiedemann syndrome (BWS). Recently, it was shown in human BWS patients, as well as mouse cell culture experiments, that Sox-Oct motifs (SOM) in the H19 ICR might play a role in protecting the maternal ICR from de novo DNA methylation. By...

We report the application of a receptor-oriented transport model, the Stochastic Time-Inverted Lagrangian Transport (STILT) model, to the interpretation of hourly total gaseous mercury (TGM) concentrations at three monitoring sites in Southern Ontario during four episodes of high TGM. STILT is a Lagrangian modelling system (Lin, J.C. et al. 2003) that simulates the transport of ensembles of air...

Genetic variability is the main characteristic when seeking to select promising genotypes for plant breeding. Thus, objective of this work was investigate genetic in agronomic and morphological characteristics traditional varieties maize, addition determining degree association selection variety characters be explored programs breeding Creole maize. The experiment conducted at Federal Universit...

A number of in vitro studies have suggested potential pathophysiological roles of human (h-) chymase. However, the lack of an appropriate animal model has left the in vivo roles of chymase unclear. To approach this problem, a transgenic mouse (TGM) model carrying the h-chymase gene was established. The h-chymase cDNA transgene was constructed with the chicken beta actin promoter and cytomegalov...

Mercury is a toxic pollutant emitted from both natural sources and through human 7 activities. A global interest in atmospheric mercury has risen ever since the discovery of the 8 Minamata disease in 1956. Properties of gaseous elemental mercury enable long range transport 9 which can cause pollution even in pristine environments. Total gaseous mercury (TGM) was 10 measured from winter 2016 to ...
