Abstract
BACKGROUND As most cystic fibrosis (CF) patients progress to respiratory failure, lung functionality assessment is pivotal. We previously developed a test that indirectly monitors airways (inflammation/functional test) by measuring the spin-spin relaxation time (T2m) of the water hydrogens present in CF sputum. Here the T2m significance in the monitoring of CF lung disease was further investigated by studying the correlation of T2m with: 1) sputum viscoelasticity, 2) mucociliary clearability index (MCI)/cough clearability index (CCI) and 3) sputum average mesh-size. METHODS Sputum samples from 25 consenting CF subjects were analyzed by rheology tests (elastic modulus G and zero shear viscosity η0) and Low Field Nuclear Magnetic (LF-NMR) resonance (T2m). MCI/CCI were calculated from the rheological parameters. The average mesh-size (ξ) of the sputum structure was then evaluated by rheology/LF-NMR, together with FEV1 for each patient. RESULTS There was an inverse correlation between G and η0 versus T2m, indicating that a worsening of the lung condition (T2m-FEV1 drop) is paralleled by an increase in sputum viscoelasticity (G and η0) favoring mucus stasis/inflammation. A direct correlation was also observed between T2m and MCI/CCI, showing that T2m provides information as to airway mucus clearing. Moreover, there was a direct correlation between T2m and the average sputum mesh size (ξ). CONCLUSIONS We demonstrated a correlation between T2m (measured in CF patient's sputum) and the sputum viscoelasticity/average mesh-size and with MCI/CCI, parameters related to airway mucus clearing. Thus, the present data strengthen the potential of our test to provide indirect monitoring of airway disease course in CF patients as T2m depends on mucus solid concentration and nanostructure.

Abstract
PURPOSE To develop a novel approach to monitor lung ventilation/inflammation in cystic fibrosis (CF) patients. Lung assessment in CF patients is relevant given that most patients succumb to respiratory failure. Respiratory functional tests (forced expiratory volume in the first second; FEV1 ) and inflammatory markers are used to test pulmonary ventilation/inflammation, respectively. However, FEV1 is effort dependent and might be uncomfortable for CF patients. Furthermore, inflammatory marker detection is costly and not rapid. To overcome these limitations, we propose the measurement, by means of low field nuclear magnetic resonance, of the spin-spin relaxation time (T2m ) of water hydrogens present in CF patient sputum. In CF sputum, different biological components are pathologically increased and inversely related to lung functionality. Moreover, we showed that these components alter in a dose-dependent manner the T2m in synthetic CF sputum. METHODS Sputum samples were obtained from 42 CF subjects by voluntary expectoration; FEV1 , C-reactive protein (CRP), blood neutrophil counts together with cytokine (tumor necrosis factor alpha [TNFα], interleukin [IL]-1β, IL-4, and vascular endothelial growth factor) quantifications were then evaluated. RESULTS In sputum samples, we observe that T2m directly correlates (rFEV1 = 0.44; P < 10-4 ; 169 samples) with FEV1 . Moreover, T2m inversely correlates with the circulating inflammation markers CRP/neutrophil number (rCRP = -0.44, P < 10-4 ; rNC = -0.37, P < 2 * 10-4 ; 103 and 86 samples, respectively) and with the sputum inflammatory cytokines TNFα/IL-β1 (rTNFα = -0.72, P < 10-4 ; rIL-1β = -0.685, P < 10-4 ; 27 samples). T2m variations also correspond to FEV1 values over time in defined patients. CONCLUSION These findings, together with the fast, reliable, and simple determination of T2m , make our approach a novel tool potentially usable in the real world of CF patients.

Abstract
OBJECTIVE Serious health problems in humans are caused by arsenic (As) exposure, which is wide spread in the environment. Sodium arsenite (SAs), capable of inducing macromolecular damage is evaluated for its damaging effect in the blood vessels, liver and kidneys of Wistar rats. This study was undertaken to investigate the ameliorative effects of thymoquinone on SAs-induced oxidative and inflammatory damages in the serum of male Wistar rats. MATERIALS AND METHODS Wistar Albino rats divided into three groups of nine rats each were administered to controls saline (10 mg/kg), SAs (10 mg/kg), and SAs plus thymoquinone (10 mg/kg/day) for two weeks orally. Biochemical tests were analyzed by a otoanalyzer; nitric oxide levels specthrophometrically, and cytokines were measured by ELISA method in the rat serum samples. RESULTS Inflammatory cytokines and some biochemical variables were found to be increased in the SAs group compared to control group. On the other hand, thymoquinone supressed these laboratory signs, which are thought to be the characteristic signs of SAs toxicity, most probably by its ameliorative effects including anti-inflammatory and antioxidant properties. CONCLUSIONS From the results obtained, thymoquinone mitigates SAs-induced adverse effects in the serum of rats, which suggest that it may attenuate inflammation implicated in endotelial dysfunction.

Abstract
We have shown that multidrug resistance associated protein 1 (MRP1) mediates ATP-dependent extrusion of bilirubin, possibly limiting its potentially toxic accumulation in cells. To determine directly if Mrp1 protects cells against unconjugated bilirubin (UCB) toxicity, mouse embryo fibroblasts (MEF) were isolated from Mrp1 knockout (-/-) mice and their wild type (WT) (+/+) littermates. Compared to WT cells, cultured MEF (-/-) cells exposed to 40-140 nM unbound [H3]-bilirubin accumulated twice as much [H3]-bilirubin (P<0.01). This was associated with greater, dose-related cytotoxicity, assessed by the methylthiazoletetrazolium test, lactate dehydrogenase release and cellular ATP content. The data confirm that Mrp1 limits intracellular accumulation of UCB and thus decreases its cytotoxicity.

Abstract
Niemann Pick disease (NPD) is an autosomal recessive disorder due to the deficit of lysosomal acid sphingomyelinase, which results in intracellular accumulation of sphingomyelin. In the present work we studied 18 patients with NPD type B, including five individuals who presented an intermediate phenotype characterised by different levels of neurological involvement. We identified nine novel mutations in the SMPD1 gene including six single base changes c.2T>G, c.96G>A, c.308T>C, c.674T>C, c.732G>C, c.841G>A (p.M1_W32del, p.W32X, p.L103P, p.L225P, p.W244C, p.A281T) and three frameshift mutations c.100delC, c.565dupC, c.575dupC (p.G34fsX42, p.P189fsX1 and p.P192fsX14). The novel c.2T>G (p.M1_W32del) mutation inactivates the first in-frame translation start site of the SMPD1 gene and in the homozygous status causes NPD type B indicating that in'vivo translation of wild type SMPD1 initiates from the first in-frame ATG. Moreover, the new c.96G>A (p.W32X) introduces a premature stop codon before the second in-frame ATG. As a consequence of either c.2T>G (p.M1_W32del) or c.96G>A (p.W32X), impaired translation from the first in-frame ATG results in a mild NPD-B phenotype instead of the severe phenotype expected for a complete deficiency of the enzyme, suggesting that when the first ATG is not functional, the second initiation codon (ATG33) still produces a fairly functional sphingomyelinase. Analysis of the patients'clinical and molecular data demonstrated that all five patients with the intermediate phenotype carried at least one severe mutation. No association between the onset of pulmonary symptoms and genotype was observed. Finally, the presence of c.96G>A (p.W32X), the most frequent allele among Italian NPD type B population, and c.1799G>C (p.R600P) as compound heterozygotes in association with severe mutations suggested a beneficial effect for both mutations.

Abstract
Recently several authors correlated MBL-2 gene polymorphisms with different pathologies and there is a growing interest for MBL-2 genotyping in a large number of individuals. We have developed a single-tube, rapid, economic, and fully automated melting temperature analysis screening method, based on ABI 7700 Sequence Detection System technology and SYBR Green I chemistry, for the detection of three polymorphisms (exon 1, codons 52, 54, 57) in the MBL-2 gene. We also developed an electronic sheet for the automatic calling of different genotypes, based on the analysis of the first derivative of ABI 7700 raw data.
