Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) studies imaging FDG PET imaging is used to detect and stage head and neck cancers. However, the variable physiologic uptake of FDG in different normal structures as well as at inflammatory sites may either obscure a tumor focus or be falsely interpreted to represent tumor activity. Twenty-one patients (9 men, 12 women, median age 59) were scanned serially at two time points, one at 70 min (range 47-112) and the second at 98 min (77-142) after the intravenous injection of 4.3 MBq/kg of FDG. The mean interval between emission scans was 28 min (13-49). Transmission scans were performed and regions of interest (ROIs) were overlayed on the fully corrected images. Standardiued uptake values (SUVs) were generated for the cerebellum, tongue, larynx, every lesion, and a matched contralateral site. Follow-up and pathologic studies revealed 18 squamous cell carcinomas and nine inflammatory or infectious lesions. Tumor SUVs were 4.0+/-1.6 (mean +/- SD) for the first scan and 4. 5+/-2.2 for the second scan. Contralateral SUVs were 1.2+/-0.5 and 1. 1+/-0.5 for the two scans. Tumor SUVs increased by 12%+/-12% as compared with a 5%+/-17% decrease for contralateral sites (P<0.05). SUVs for inflammatory sites (2.0+/-0.7 and 2.0+/-0.9), cerebellum (4. 2+/-1.3 and 4.3+/-1.4), tongue (1.8+/-0.4 and 1.9+/-0.5) and larynx (1.5+/-0.6 and 1.5+/-0.6) remained constant over time (+0.6%, +2.8%, +1.4%, and -2.4%; P<0.05 when compared with tumor SUV changes). The ratio tumor/contralateral SUV increased by 23%+/-29% over time while this ratio for inflamed sites increased by only 5%+/-15% (P=0.07). The time interval between scans correlated with increase in SUV for tumors (r=0.55, P<0.05) but not for any of the other ROIs. Separation was superior when studies were performed more than 30 min apart (P<0.05). These preliminary data suggest that dual time point imaging compatible with a clinical study protocol is helpful in differentiating malignant lesions from inflammation and normal tissues, especially when separated by a sufficient time interval.

The Extreme Ultraviolet Imager (EUI) on-board the Solar Orbiter mission will provide image sequences of the solar atmosphere at selected spectral emission lines in the extreme and vacuum ultraviolet. For the two Extreme Ultraviolet (EUV) channels of the EUI instrument, low noise and radiation tolerant detectors with low power consumption and high sensitivity in the 10-40 nm wavelength range are required to achieve the science objectives. In that frame, a dual-gain 10 µm pixel pitch back-thinned 1k x 1k Active Pixel Sensor (APS) CMOS prototype has been tested during the preliminary development phase of the instrument, to validate the pixel design, the expected EUV sensitivity and noise level, and the capability to withstand the mission radiation environment. Taking heritage of this prototype, the detector architecture has been improved and scaled up to the required 3k x 3k array. The dynamic range is increased, the readout architecture enhanced, the power consumption reduced, and the pixel design adapted to the required stitching. The detector packaging has also been customized to fit within the constraints imposed by the camera mechanical, thermal and electrical boundaries. The manufacturing process has also been adapted and back-thinning process improved. Once manufactured and packaged, a batch of sensors will undergo a characterization and calibration campaign to select the best candidates for integration into the instrument qualification and flight cameras. The flight devices, within their cameras, will then be embarked on the EUI instrument, and be the first scientific APS-CMOS detectors for EUV observation of the Sun. [less ▲]

We report the generation of dual-specificity phosphatase 3 (DUSP3) deficient mice. These mice develop normally and do not exhibit any spontaneous phenotype. However, VHR-/- females, but not males, are resistant to LPS- and to polymicrobial infection-induced septic shock. After LPS injection, while VHR-/- males and VHR+/+ mice of both genders, displayed an increased serum levels of TNF-α and IFN, the levels of these cytokines remained significantly low in the VHR-/- females. In vitro experiments using peritoneal macrophages showed the same results suggesting that the systemic cytokines profiles observed are macrophages-dependent. Adoptive transfer of VHR-/- females bone marrow to irradiated VHR+/+ female mice, but not to VHR-/- or VHR+/+ males, protected them from death after administration of LPS. Interestingly, VHR-/- females were sensitive to TNF-α- induced lethality. We also report that the decrease of TNF-α production observed in VHR-/- female’s macrophages after LPS activation was associated with a decreased ERK1/2, but not MEK1/2, activation. Interestingly, pervanadate (PTP pan inhibitor) treatment prior to LPS activation restored ERK1/2 activation in the VHR-deficient macrophages, suggesting that VHR is targeting one of the ERK1/2 PTPs or DUSPs. These results, together with our observation that DUSP3 is the most highly expressed phosphatase in macrophages, suggest a key non-redundant role of VHR as positive regulator of TNF-α in innate immune response in females.

The relationship between mind and brain has philosophical, scientific, and practical implications. Two separate but related surveys from the University of Edinburgh (University students, n= 250) and the University of Liege (health-care workers, lay public, n= 1858) were performed to probe attitudes toward the mind-brain relationship and the variables that account for differences in views. Four statements were included, each relating to an aspect of the mind-brain relationship. The Edinburgh survey revealed a predominance of dualistic attitudes emphasizing the separateness of mind and brain. In the Liege survey, younger participants, women, and those with religious beliefs were more likely to agree that the mind and brain are separate, that some spiritual part of us survives death, that each of us has a soul that is separate from the body, and to deny the physicality of mind. Religious belief was found to be the best predictor for dualistic attitudes. Although the majority of health-care workers denied the distinction between consciousness and the soma, more than one-third of medical and paramedical professionals regarded mind and brain as separate entities. The findings of the study are in line with previous studies in developmental psychology and with surveys of scientists' attitudes toward the relationship between mind and brain. We suggest that the results are relevant to clinical practice, to the formulation of scientific questions about the nature of consciousness, and to the reception of scientific theories of consciousness by the general public.

This research analyzes the gender dimensions of labor migration and agricultural production among farm households in Red River Delta region of Vietnam. Through surveying 215 households in Bac Ninh province, the paper explores impacts of female and male migration on agricultural production and its implications on rural development. The results show that in comparison to male migration household, the female one tends to focus on agricultural production by taking the opportunities to rent more land (26.3%) and effective use their own allocated land for agricultural production (97.4%). The overall impacts of migration on agricultural production are the aging of farm labor force (49.6 year old in average) and higher female participation in agricultural production. The findings suggest that female migrants have a greater contribution in agriculture production both in term of working time and agricultural capital investment while male migrants enhance household income by accumulating capital outside agriculture. Through the gender lens, this research emphasizes the duality in the nature of migrant lives and the implications of rural labor migration on the fixed categories. [less ▲]

We report on two sisters who show a similar pattern of anomalies consisting of bilateral Stilling-Turk-Duane retraction syndrome (type 3), non-progressive hypotonia with delayed motor milestones but normal intelligence, severe, early onset scoliosis, and short stature. Muscular biopsy revealed numerous regenerating fibers, but no specific abnormalities among the non-regenerating fibers. This combination of anomalies has not been previously reported, and could represent a new autosomal recessive syndrome. The only differential diagnosis is Crisfield-Dretakis-Sharpe syndrome, a combination of lateral gaze palsy, ptosis, and scoliosis without hypotonia, recessively inherited. [less ▲]
