Serum, red cell, urinary and bone Mg levels have been measured in 10 post-menopausal osteoporotics. Osteoporosis was confirmed by clinical fracture, histological analysis and dual-photon absorptiometry quantification. When compared to a healthy population matched for age and sex, serum Mg levels were statistically significantly (p less than 0.05) lower in osteoporotics (0.82 +/- 0.06 mmol/l) compared to normal subjects (0.87 +/- 0.04 mmol/l). No difference appeared for red cell, urinary or bone Mg determination. If these results are confirmed in a long-term study, serum Mg might be added to a batch of tests used to discriminate a subset of patients with an increased risk of developing postmenopausal osteoporosis.

Jupiter was observed by the Chandra X-ray Observatory in late February, 2003, for 144 ks, using both the ACIS-S and HRC-I imaging x-ray cameras. Five orbits of HST STIS observations of the planet's northern auroral zone were obtained during the ACIS-S observations. These data are providing a wealth of information about Jupiter's auroral activity, including the first x-ray spectra from the x-ray hot spots inside the auroral ovals. We will also discuss time variability in the auroral x-ray emission and a possible phase relation between the emission from the northern and southern x-ray aurora. [less ▲]

We present preliminary results from observations of the massive WR+O binary WR 22 performed with the XMM observatory. The star is brighter in the X-ray domain near apastron and fainter at periastron. The change in brightness is very progressive and mainly corresponds to a lowering of the soft part of the spectrum. [less ▲]

In goat and sheep, the glycoproteins associated to pregnancy (PAG) are little studied. Their study in these species is very important in the evaluation of prediction of early pregnancy. Even though numerous research has been done in order to investigate the physiological functions of placental proteins, the exact biofunction of the glycoproteins associated to pregnancy is still unknown. The objective of research was the study of the dynamics of PAG in goats and ewes in the first part of pregnancy(1-35 days after mating) and the determination of correlations with the reproductive status of females and to earlier the pregnancy.The experiment was realized on 49 Saanen x Carpatina goats and 72 Merinos of Palas sheep from the biostation of the Research and Development Institute for Goat and Sheep, Palas Constanta. The females in normal reproduction season were monitored for the detection of estrus and mated naturally. The blood was collected by puncture of the jugular vein on days 0, 7, 14, 25 and 35 after mating (day 0). The serum was obtained after centrifuging at 1500 x g for 15 minutes and stored at -20oC till the RIA determination. The RIA of the plasma with the purpose of detecting the concentration of proteins specific to pregnancy was realized in two experimental series in February and December 2008, at the Laboratory for Reproduction Physiology – The Faculty of Veterinary Medicine, Liege, Belgium. The RIA dosing was realized after the application of the method with the preincubation of the serums to test with specific serum (Atg°) and then with the marked antigen (Atg*), considering the high sensitivity of this method to detect the smallest values of PAG from day 0 to day 35 after mating. The diagnosis of the pregnancy state was based on the principle of PAG antibodies binding to the specific antigen, establishing through RIA the quantity of free antigen. Non-pregnancy involves the attachment of the antigen marked by non-specific antibodies. The preliminary results have demonstrated that the sheep PAG were had values ranging between 4.197-15.985 ng/ml and 0.01-3.39 ng/ml in nonpregnant ewes. In the pregnant goats, the PAG concentrations ranged between 16.75±3.44-27.17±2.95 ng/ml, while in the nonpregnant goats, the PAG values were 1.38±0.35 – 2.03±0.51 6 ng/ml. The purpose of the experiments was to find one accurate method for early pregnancy diagnosis in goat and sheep. The conclusion was that ovine pregnancy can be reliably diagnosed on Day 25 after AI and goat pregnancy on Day 30, by using a heterologous radioimmunoassay of PAG. [less ▲]

We present preliminary results of an observational campaign aiming at the study of the binary system LSS3074. A new lightcurve clearly indicates that the system is in contact. Recent spectroscopy broadly confirms the previous results and the rather low masses of both components (O4f[SUP]+[/SUP] and O6-7:(f):). We further analyse an XMM-Newton observation of the object that indicates a rather hard X-ray spectrum. This is partly due to the high interstellar extinction towards the object but also to the high plasma temperature (kT Ë 1.2-1.3 keV). [less ▲]

Objective: this study examined the generic and CF-specific QOL in CF children using a tool based on a modular clinical approach. Methods: Sample consisted of 12 CF children and 12 healthy children aged 8 to 12 years, matched by age and sex. The Quality of Life Systemic Inventory for Children (QLSI-C) assess both generic (20 items) and CF-specific (6 items) QOL. CF-specific module is empirically created from CFQ-R and discussion with medical staff. QLSI-C is a dynamic tool, using a VAS, which considers QOL (gap) like the difference between the present situation (state) and the expectations (goal). This difference is weighted by the importance (rank) that children assign for each life domains. QLSI-C is different from PedQoL, which consider QOL like an assessment of state score only. Results: Difference between CF and healthy children for the QOL score approached significance (F=3.63; p=0.07). Results by items show a significant difference for “autonomy” (F=4.30; p=0.05) and “frustration tolerance” (F=4.60; p=0.04) between the two groups. In addition, global scores in CF-specific module is correlated with global score in generic module for CF children (r=0.66 to 0.96). Assessment of QOL is the same for both generic (M=3.76) and CF-specific (M=3.76) module (p=0.53). Finally, descriptive statistics demonstrate that items which reflect the best QOL in CF children were based on social support unlike healthy children. Conclusion: QLSI-C is a clinical tool which distinguishes between children with CF and healthy children. Originality of this tool is strengthened by the consideration of individual life plan taking into account the particular situation of children with CF. [less ▲]

Humic substances (HS) are organic compounds resulting from the physical, chemical and microbiological transformations of organic residues. Present everywhere in the nature; they are taking part in basic functionalities in any ecosystems involving soils, sediments, water and landfills. They are heterogeneous and complex carbon macromolecules. Our study aims to determine the main biological properties of HS on plant growth in relation to their physicochemical properties. [less ▲]
