Discusses the abstract of the article "Postmenopausal osteoporosis and alendronate," by F.R. Perez-Lopez and colleagues, published in a 2004 issue of the periodical "Maturitas".

IS6110 augments phoP transcription in an outbreak strain of drug-resistant tuberculosis. "Drug resistance in Mycobacterium tuberculosis complex strains is solely due to chromosomal mutations that could affect bacterial virulence," according to biologists in Spain. "Molecular epidemiology studies have shown that resistant strains are less likely to be clustered than susceptible strains. However, a few multidrug-resistant Mycobacterium tuberculosis complex strains have been described as causing outbreaks, suggesting that they have restored virulence or increased transmission."

Reports on the findings of a research conducted at the University of Zaragoza and published in the "IEEE Transactions on Medical Imaging" regarding the capability of a registration-based imaging analysis technique in providing measurement of flow-mediated dilation.

Details of a clinical study on the actions of the vaccine; Proportion of mortality rates found in adult rabbits with natural antibodies to the disease; Response of the subjects previously exposed to the antigens.

Reports on the reduction of insulin-like growth factor-I (IGF-I) in placental tissue from pregnancies with intrauterine growth retardation. Investigation of the possibility of altered gene expression of growth factors in prenatal growth retardation; Assessment of the expression of the genes for IGF-I and epidermal growth factor receptor; Description of the placentas from IUGR gestations.

A study published in the 2004 issue of the journal "Cytokine" and conducted by researcher J. Garcia-Herrera and colleagues, states that tumor necrosis factor-alpha reduced D-fructose intestinal transport in rabbits. According to this study from Spain, "Tumor necrosis factor-alpha (TNF-alpha) is an important immunoregulatory cytokine involved in septic responses during bacterial infection. The aim of this study was to examine the effect of TNF-alpha on the transport of D-fructose across rabbit jejunum. A sepsis condition was evoked by intravenous administration of this cytokine and hematological and plasma parameters were analyzed and body temperature was recorded. D-Fructose transport was assayed in rabbit jejunum."
