Insulin causes a transient induction of proliferation via activation of the PI3-kinase pathway in airway smooth muscle cells
(2007)
Insulin regulates glucose metabolism and activates cell growth. As the respiratory system is an alternative route for insulin administration in patients with diabetes mellitus, we studied the effect of insulin on rabbit ...
Mechanisms of action of differentiation inducers: Detection of inducer binding protein(s) in murine erythroleukemia cells
(2005)
We have shown previously that murine erythroleukemia (MEL) and human neuroectodermal RD/TE-671 cells are induced to differentiate by ureido derivatives of pyridine (UDPs) and may contain inducer binding protein(s). In the ...
Age-specific and lifetime behavior patterns in Drosophila melanogaster and the Mediterranean fruit fly, Ceratitis capitata
(2006)
Patterns of behavior were recorded every 10 min during a 2-h period each day from eclosion to death for individual Drosophila melanogaster (both sexes) and Ceratitis capitata (males-only) including walking, preening, ...
Age structure changes and extraordinary lifespan in wild medfly populations
(2008)
The main purpose of this study was to test the hypotheses that major changes in age structure occur in wild populations of the Mediterranean fruit fly (medfly) and that a substantial fraction of individuals survive to ...
Survey of methicillin-resistant coagulase-negative staphylococci in the hospitals of central Greece
(2001)
A sample of 450 consecutive, non-replicated coagulase-negative staphylococci (CoNS), collected from clinical specimens during the period 2000-2001 from the five major hospitals of Thessaly district (Central Greece) were ...
Crocus sativus L. extracts antagonize memory impairments in different behavioural tasks in the rat
(2006)
The effects of extracts of Crocus sativus L. (CSE), on memory were investigated in the rat by using the object recognition and the step-through passive avoidance task. In the first study, post-training administration of ...
The Developmental Program of Murine Erythroleukemia Cells
(2002)
Hematopoietic stem cells (HSCs) or early progenitors respond to external stimuli in bone marrow and differentiate into cell-restricted lineages of blood cells of limited life span. In leukemias, however, early hematopoietic ...
Demographic window to aging in the wild: Constructing life tables and estimating survival functions from marked individuals of unknown age
(2004)
We address the problem of establishing a survival schedule for wild populations. A demographic key identity is established, leading to a method whereby age-specific survival and mortality can be deduced from a marked cohort ...
Mycobacterium tuberculosis transmission among high school students in Greece
(2005)
Background: The aim of this study was to investigate the requirements and practical steps for screening of Mycobacterium tuberculosis (MTB) transmission among high school student populations in two regional high schools ...
