We develop the formalism of the macroscopic monopolization—that is, the magnetoelectric monopole moment per unit volume—in periodic solids, and discuss its relationship to the magnetoelectric effect. For the series of lithium transition metal phosphate compounds, we use first-principles density functional theory to calculate the contributions to the macroscopic monopolization from the global distribution of magnetic moments within the unit cell, as well as from the distribution of magnetization around the atomic sites. We find one example within the series (LiMnPO4) that shows a macroscopic monopolization corresponding to a ferromonopolar ordering consistent with its diagonal magnetoelectric response. The other members of the series (LiMPO4, with M=Co, Fe, and Ni) have zero net monopolization but have antiferromonopolar orderings that should lead to q-dependent diagonal magnetoelectric effects.

We present four children from two families with the typical 11q- phenotype resulting from an unbalanced segregation of a parental translocation. In the first family, the father had a 46,XY,t(5;11)(q24;q23.3) constitution. The father of the three other children had a 46,XY,t(11;17)(q23;p13) translocation. Despite associated partial deletion, three of the children had a typical 11q- phenotype. The fourth one, whose pregnancy was terminated in the second trimester, had a hypoplastic left heart but no other considered gross anomalies. A review of 36 previous cases, including 5 due to translocations (4 familial rearrangements, and 1 of unknown origin) is given with emphasis on the relationships between break-points and phenotype. Undescribed manifestations in our patients include agenesis of corpus callosum adactyly and malrotation of the gut. [less ▲]

CONTEXT: Glioblastomas--uniformly fatal brain tumors--often have both monosomy of chromosome 10 and gains of the epidermal growth factor receptor (EGFR) gene locus on chromosome 7, an association for which the mechanism is poorly understood. OBJECTIVES: To assess whether coselection of EGFR gains on 7p12 and monosomy 10 in glioblastomas promotes tumorigenic epidermal growth factor (EGF) signaling through loss of the annexin A7 (ANXA7) gene on 10q21.1-q21.2 and whether ANXA7 acts as a tumor suppressor gene by regulating EGFR in glioblastomas. DESIGN, SETTING, AND PATIENTS: Multidimensional analysis of gene, coding sequence, promoter methylation, messenger RNA (mRNA) transcript, protein data for ANXA7 (and EGFR), and clinical patient data profiles of 543 high-grade gliomas from US medical centers and The Cancer Genome Atlas pilot project (made public 2006-2008; and unpublished, tumors collected 2001-2008). Functional analyses using LN229 and U87 glioblastoma cells. MAIN OUTCOME MEASURES: Associations among ANXA7 gene dosage, coding sequence, promoter methylation, mRNA transcript, and protein expression. Effect of ANXA7 haploinsufficiency on EGFR signaling and patient survival. Joint effects of loss of ANXA7 and gain of EGFR expression on tumorigenesis. RESULTS: Heterozygous ANXA7 gene deletion is associated with significant loss of ANXA7 mRNA transcript expression (P = 1 x 10(-15); linear regression) and a reduction (mean [SEM]) of 91.5% (2.3%) of ANXA7 protein expression compared with ANXA7 wild-type glioblastomas (P = .004; unpaired t test). ANXA7 loss of function stabilizes the EGFR protein (72%-744% increase in EGFR protein abundance) and augments EGFR transforming signaling in glioblastoma cells. ANXA7 haploinsufficiency doubles tumorigenic potential of glioblastoma cells, and combined ANXA7 knockdown and EGFR overexpression promotes tumorigenicity synergistically. The heterozygous loss of ANXA7 in approximately 75% of glioblastomas in the The Cancer Genome Atlas plus infrequency of ANXA7 mutation (approximately 6% of tumors) indicates its role as a haploinsufficiency gene. ANXA7 mRNA transcript expression, dichotomized at the median, associates with patient survival in 191 glioblastomas (log-rank P = .008; hazard ratio [HR], 0.667; 95% confidence interval [CI], 0.493-0.902; 46.9 vs 74.8 deaths/100 person-years for high vs low ANXA7 mRNA expression) and with a separate group of 180 high-grade gliomas (log-rank P = .00003; HR, 0.476; 95% CI, 0.333-0.680; 21.8 vs 50.0 deaths/100 person-years for high vs low ANXA7 mRNA expression). Deletion of the ANXA7 gene associates with poor patient survival in 189 glioblastomas (log-rank P = .042; HR, 0.686; 95% CI, 0.476-0.989; 54.0 vs 80.1 deaths/100 person-years for wild-type ANXA7 vs ANXA7 deletion). CONCLUSION: Haploinsufficiency of the tumor suppressor ANXA7 due to monosomy of chromosome 10 provides a clinically relevant mechanism to augment EGFR signaling in glioblastomas beyond that resulting from amplification of the EGFR gene.

Terpenes are recurrent in indoor environments. Their sources, biogenic or anthropological origin, are very varied: plants, wooden building materials, household products and furnishings, paints, air fresheners, perfumed candles. However, in spite of their natural character, these compounds can have significant effects on occupant’s health. Indeed, some monoterpenes are recognized as irritating or allergenic. Furthermore, they react with the other molecules to form potentially more harmful secondary products such as formaldehyde. Numerous studies demonstrated that reactions between monoterpenes and ozone produced airborne particulate matter as well as secondary pollutants among which formaldehyde, acetaldehyde and acetone. However, few studies were realized in the indoor to demonstrate the terpenes and secondary pollutants evolution. The most frequently used technique for the monoterpenes analysis is the TD-GC-MS. The sampling mode depends on the sample introduction system, either the sampling on sorbent tube, or the sampling in a tank. The attraction for the wooden constructions and ecological materials leads to higher indoor monoterpenes concentrations. Does this occurrence have to arouse our interest? The present article has the objective to review the knowledge relative to terpenes, and more exactly on the monoterpenes sources in indoor and their implication in its quality. [less ▲]

There has been a growing interest for exhaled biomarkers. We review studies examining NO as a potential marker of airway inflammation, enabling noninvasive repeated monitoring of airway inflammation. The measurement technique has been standardized. We have determined the local normal levels for the Liege region. The exhaled NO level is elevated in asthma, and can predict asthma exacerbation. Exhaled NO has a value for the diagnosis of cystic fibrosis and primary ciliary dyskinesia. [less ▲]
