Polar lipid remodeling and increased sulfatide expression are associated with the glioma therapeutic candidates, wild type p53 elevation and the topoisomerase-1 inhibitor, irinotecan

We report changes in gene and polar lipid expression induced by adenovirus-delivered wild-type (wt) p53 gene and chemotherapy of U87 MG glioblastoma cells, a treatment known to trigger apoptosis and cell cycle arrest. Sulfatides (sulfonated glycolipids) were most highly modulated by wild-type p53 treatment; however, no changes were observed in expression levels of mRNA for genes involved in sulfat

Comparative genome- and proteome analysis of cerebral cortex from MK-801-treated rats

cDNA microarrays and two-dimensional gel-electrophoresis in combination with mass spectrometry, were used to screen alterations in mRNA and protein levels, respectively, in cerebral cortex of MK-801-treated rats. The rats were divided in two groups; group 1 (short-term treated) and group 2 (long-term treated). In group 1, four genes were up-regulated and five down-regulated. In group 2, seven gene

An investigation of the interaction between red blood cells and Streptococcus pyogenes

Blood group antigens may be used as receptors by pathogens when infecting their hosts. Different blood groups therefore can be disease susceptibility factors. Thus, pathogens may have exerted a selection pressure on the evolution of blood group diversity. One aim of our study was to identify red blood cell (RBC) membrane structures that are bound by the common human pathogen. Streptococcus pyogene

Prognosis of patients without perfusion defects with and without rest study in myocardial perfusion scintigraphy

Background: Stress myocardial perfusion scintigraphy (MPS) is widely regarded as a useful imaging modality for diagnosing patients with suspected ischemic heart disease. Current European guidelines recommend stress study to be performed first since rest study can be omitted if stress study is interpreted as normal. Thus, a rest study should only be performed in patients with equivocal or abnormal

Hypertension reduces soluble guanylyl cyclase expression in the mouse aorta via the Notch signaling pathway

Hypertension is a dominating risk factor for cardiovascular disease. To characterize the genomic response to hypertension, we administered vehicle or angiotensin II to mice and performed gene expression analyses. AngII treatment resulted in a robust increase in blood pressure and altered expression of 235 genes in the aorta, including Gucy1a3 and Gucy1b3 which encode subunits of soluble guanylyl c

Oxygen dynamics in the aftermath of the Great Oxidation of Earth's atmosphere

The oxygen content of Earth's atmosphere has varied greatly through time, progressing from exceptionally low levels before about 2.3 billion years ago, to much higher levels afterward. In the absence of better information, we usually view the progress in Earth's oxygenation as a series of steps followed by periods of relative stasis. In contrast to this view, and as reported here, a dynamic evolut

Do large predatory fish track ocean oxygenation?

The Devonian appearance of 1-10 meter long armored fish (placoderms) coincides with geochemical evidence recording a transition into fully oxygenated oceans.1 A comparison of extant fish shows that the large individuals are less tolerant to hypoxia than their smaller cousins. This leads us to hypothesize that Early Paleozoic O(2) saturation levels were too low to support >1 meter size marine, pred

Immunohistochemical markers in full-thickness embryonic rabbit retinal transplants

PURPOSE: To examine immunohistochemical markers in straight, well-laminated retinal transplants with special attention paid to the interphotoreceptor matrix, the Müller cells and the ganglion cells as these three retinal components have been abnormal in transplants produced by previous methods.METHODS: Nine rabbits underwent subretinal transplantation of a complete full-thickness embryonic neurore

Transplant of full-thickness embryonic rabbit retina using pars plana vitrectomy

PURPOSE: To develop an improved surgical technique making full-thickness retinal transplant possible, thereby achieving a normal laminated transplant with minimal rosette formation.METHODS: A total of 23 rabbits underwent vitrectomy, retinotomy, and subsequent subretinal transplant of a complete embryonic neuroretina using a specially crafted glass cannula. Of the 23 animals, 15 received a prenata

Minding Equality: Compulsory Mental Health Interventions and the CRPD : Compulsory Mental Health Interventions and the CRPD

This study delineates the permissible scope for compulsory mental health interventions under the Convention on the Rights of Persons with Disabilities (CRPD). It was initially triggered by two competing positions within the current debate over the future of coercive psychiatry; a practice that is still omnipresent among states worldwide. According to one position, defended by the CRPD Committee amThis study delineates the permissible scope for compulsory mental health interventions under the Convention on the Rights of Persons with Disabilities (CRPD).

Experimental determination of dose conversion coefficients for external radiation exposure with gamma emitting radionuclides

Abstract in Russian В данной работе был использован фантом Алдерсон-РАНДО для экспериментального определения коэффициентов перехода для условий внешнего облучения. Были смоделированы следующие конфигурации облучения: ротационная геометрия облучения с использованием различных точечных источников (99mTc, 131I + 133Ba, 137Cs, 60Co); передне-задняя и задне-передняя геометрия облучения источником 137CsIn the present paper the Alderson RANDO phantom have been used to experimentally determine conversion coefficients. A limited number of exposure situations were investigated for this purpose: rotational-geometry with different radiation point sources (99mTc, 131I+133Ba, 137Cs, 60Co), AP- and PA-geometry with 137Cs and a special pocket-geometry with 137Cs. All experiments were carried out on a larg
