Significant correlations were often found between pollutants from the same family, with the strongest being found between two PYR metabolites, trans/cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-carboxylic acid (Cl2CA) and 3-phenoxybenzoic acid (3-PBA). Results from multiple linear regression analyses showed that sex, age and/or body mass index were significantly associated with 15 out of the 17 frequently detected pollutants. The current study is the first nationwide biomonitoring investigating organic contaminants in the Luxembourg population using hair analysis.Potocki-Lupski syndrome (PTLS; MIM 610883) is a neurodevelopmental disorder associated with a 3.7 Mb copy number variant (CNV) duplication, locating in chromosome 17p11.2. (Soler-Alfonso et al., 2011). Here, a human induced pluripotent stem cell (iPSC) line was derived from the peripheral blood mononuclear cells of a 5-year-old child suffering Potocki-Lupski syndrome. The generated iPSCs were integration-free, had the 17p11.2 3.7 Mb CNV duplication with no additional genomic alterations, a stable karyotype, expressed pluripotency stem cell markers and could differentiate towards the three germ layers in vitro. Patient's derived iPSCs are a valuable resource for in vitro modeling of 17p11.2 microduplication induced Potocki-Lupski syndrome.Surfactant dysfunction is a genetically heterogeneous pulmonary disease that causes dyspnea. ATP binding cassette protein transporter subunit A3 (ABCA3) is the main pathogenic gene of pulmonary surfactant dysfunction. In this study, we established an induced pluripotent stem cell line (SMCPGHi001-A) from the peripheral blood cells of a 49-day-old male infant, carrying compound heterozygous variations of the ABCA3 gene (c.3997_3998del, p.R1333fs, and c.3137C > T, p.A1046V). This iPSC line would be a useful tool to study the pathogenesis, disease development, and treatment of pulmonary surfactant dysfunction.Human induced pluripotent stem cells (hiPSC) line FLENIi001-A was reprogrammed from dermal fibroblasts using the lentiviral-hSTEMCCA-loxP vector. Fibroblasts were obtained from a skin biopsy of a 72-year-old Caucasian male familial Alzheimer's disease patient carrying the T119I mutation in the PSEN1 gene. PSEN1 genotype was maintained and stemness and pluripotency confirmed in the FLENIi001-A hiPSC line.As the frequency of cannabis-based therapy increases, the ability to distinguish intake of cannabis-based medicines from recreational cannabis use becomes desirable. Minor cannabinoids have been suggested to indicate recreational cannabis use in biological matrices but are unreliable when presumably also present in directly plantderived medicines. Thus, for therapeutics such as medical cannabis, Sativex® and Dronabinol, a more thorough investigation of cannabinoid profiles is required to identify possible distinguishing markers. In this study, 16 phytocannabinoids were quantified in samples of seized and medical cannabis, Sativex® and Dronabinol from two different manufacturers, using a validated LC-MS/MS method. Analytes included delta-9- tetrahydrocannabinol, tetrahydocannabinolic acid A, cannabidiol, cannabidiolic acid, cannabigerol, cannabigerolic acid, cannabinol, cannabinolic acid, cannabichromene, cannabichromenic acid, cannabicyclol, cannabicyclolic acid, tetrahydrocannabivarin, tetrahydrocannabivarinic acid, cannabidivarin and cannabidivarinic acid. Resultant cannabinoid profiles were compared, and markers were suggested. Characteristics of Sativex® included a specific cannabidiol/tetrahydrocannabinol ratio and presence of cannabichromene, while acidic cannabinoids, cannabigerol and cannabinol occurred in only low amounts. As expected, the predominant ingredient in Dronabinol was tetrahydrocannabinol, but minor cannabinoids were quantified as well. Medical marihuana and seized cannabis were compared separately in a principal component analysis. Several medical marihuana varieties were found to significantly differ from seized cannabis, mostly regarding contents of tetrahydocannabinolic acid A and tetrahydrocannabivarinic acid and cannabidiolic and cannabidivarinic acid respectively.

Limited diagnostic options exist for patients with suspected pulmonary embolism (PE) who cannot undergo CT-angiogram (CTA). CT-ventilation methods recover respiratory motion-induced lung volume changes as a surrogate for ventilation. We recently demonstrated that pulmonary blood mass change, induced by tidal respiratory motion, is a potential surrogate for pulmonary perfusion. In this study, we examine blood mass and volume change in patients with PE and parenchymal lung abnormalities (PLA).

A cross-sectional analysis was conducted on a prospective, cohort-study with 129 consecutive PE suspected patients. Patients received 4DCT within 48h of CTA and were classified as having PLA and/or PE. Global volume change (VC) and percent global pulmonary blood mass change (PBM) were calculated for each patient. Selleck Rilematovir Associations with disease type were evaluated using quantile regression.

68 of 129 patients were PE positive on CTA. Median change in PBM for PE-positive patients (0.056; 95% CI 0.045, 0.068; IQR 0.051) was smaller than that of PE-negative patients (0.077; 95% CI 0.064, 0.089; IQR 0.056), with an estimated difference of 0.021 (95% CI 0.003, 0.038; p=0.0190). PLA was detected in 57 (44.2%) patients. Median VC for PLA-positive patients (1.26; 95% CI 1.22, 1.30; IQR 0.15) showed no significant difference from PLA-negative VC (1.25; 95% CI 1.21, 1.28; IQR 0.15).

We demonstrate that pulmonary blood mass change is significantly lower in PE-positive patients compared to PE-negative patients, indicating that PBM derived from dynamic non-contrast CT is a potentially useful surrogate for pulmonary perfusion.

Here we report a novel perceptual size illusion that the self-face, being a unique and distinctive self-referential stimulus, can enlarge its perceived size. By using a size discrimination paradigm, we found that the self-face was perceived as significantly larger than the other-face of the same size. This size overestimation effect was not due to the familiarity of the self-face, since it could be still observed when the self-face was directly compared with a famous face. More crucially, such illusion effect could be extended to a new cartoon face that was transiently associated with one's own face and could also exert further contextual influences on visual size perception of other objects. These findings together highlight the role of self-awareness in visual size perception and point to a special mechanism of size perception tuned to self-referential information.
