A Clinical Update of the Hb Siirt [β27(B9)Ala→Gly; HBB: c.83C>G] Hemoglobin Variant.

We report a clinical update of the hemoglobin (Hb) variant [β27(B9)Ala→Gly; HBB: c.83C>G], named Hb Siirt, that was previously described as a silent variant in a 23-year-old Kurdish female. The patient was also a carrier of the codon 5 (-CT) (HBB: c.

DEHP effects on retinal vessels in newborn rats: a qualitative and quantitative analysis.

Di-(2-ethylhexyl)-phthalate (DEHP), employed in polyvinyl chloride fabrication and released by endotracheal tubes, is known to cause alterations to several mammalian tissues, markedly in immature animals. The high incidence and severity of bronchopulmonary dysplasia and retinopathy in preterm babies submitted to endotracheal intubation prompted us to investigate the effects of DEHP in lung and retina perinatal development. We previously demonstrated that in rats delivered and breast-fed by DEHP-treated mothers lung alveolarisation is severely impaired.

NF-kB/NOS cross-talk induced by mitochondrial complex II inhibition: implications for Huntington's disease.

Nuclear factor-kB (NF-kB) is a family of DNA-binding proteins that are important regulators involved in immune and inflammatory responses, as well as in cell survival and apoptosis. In the nervous system NF-kB is activated under physiological and pathological conditions including learning and memory mechanisms and neurodegenerative diseases. NF-kB is activated in neurons in response to excitotoxic, metabolic and oxidative stress and there is a body of evidence to suggest that glutamate induces NF-kB by the main ionotropic glutamate receptors.
