BACKGROUND Dietary restriction (DR) has been shown to prolong longevity across diverse taxa, yet the mechanistic relationship between DR and longevity remains unclear. MicroRNAs (miRNAs) control aging-related functions such as metabolism and lifespan through regulation of genes in insulin signaling, mitochondrial respiration, and protein homeostasis. RESULTS We have conducted a network analys...

Plant growth promoting endophytic bacteria (PGPB) isolated from Brassica napus were inoculated in two cultivars of Helianthus tuberosus (VR and D19) growing on sand supplemented with 0.1 mM Cd or 1 mM Zn. Plant growth, concentrations of metals and thiobarbituric acid (TBA) reactive compounds were determined. Colonization of roots of H. tuberosus D19 by Pseudomonas sp. 262 was evaluated using co...

The MN1 oncogene is deregulated in human acute myeloid leukemia and its overexpression induces proliferation and represses myeloid differentiation of primitive human and mouse hematopoietic cells, leading to myeloid leukemia in mouse models. To delineate the sequences within MN1 necessary for MN1-induced leukemia, we tested the transforming capacity of in-frame deletion mutants, using retrovira...

Abstract Background Intravenous immunoglobulins (IVIG) therapy is increasingly used in the treatment of various paediatric diseases. Data about frequency and underlying mechanisms IVIG-related adverse events (IVIG-AEs) children are limited. Objectives this study were to document incidence IVIG-AEs hospitalized patients identify risk factors for IVIG-AEs. Design/Methods In retrospective cohort s...

Microbial infections of the cornea are potentially devastating and can result in permanent visual loss or require vision-rescuing surgery. In recent years, there has been an increasing number of reports on nontuberculous mycobacterial infections of the cornea. Challenges to the management of nontuberculous mycobacterial keratitis include delayed laboratory detection, low index of clinical suspi...

Degradation of polycyclic aromatic hydrocarbons (PAHs), including polychlorinated dioxins/furans (PCDD/Fs), by microorganisms has received much attention in connection with natural attenuation and bioremediation of xenobiotic pollution (Hiraishi, 2003; Wittich, 1998). Large numbers of aromaticand PAHdegrading bacteria from polluted environments have been isolated and characterized. The so-calle...
