The SOHO (SOlar and Heliospheric Observatory) satellite was launched on December 2nd 1995. After arriving at the Earth-Sun (L1) Lagrangian point on February 14th 1996, it began to continuously observe the Sun. As one of the instruments onboard SOHO, the EIT (Extreme ultraviolet Imaging Telescope) images the Sun's corona in 4 EUV wavelengths. The He II filter at 304 AË images the chromosphere and the base of the transition region at a temperature of 5 - 8 x 10^4 K; the Fe IX-X filter at 171 AË images the corona at a temperature of ~ 1.3 x 10^6 K; the Fe XII filter at 195 AË images the quiet corona outside coronal holes at a temperature of ~ 1.6 x 10^6 K; and the Fe XV filter at 284 AË images active regions with a temperature of ~ 2.0 x 10^6 K. About 5000 images have been obtained up to the present. In this paper, we describe also some aspects of the telescope and the detector performance for application in the observations. Images and movies of all the wavelengths allow a look at different phenomena present in the Sun's corona, and in particular, magnetic field reconnection. [less ▲]

Sixty Prim'holstein cows with retained placenta for more than 24 hours after parturition, were shared in three groups of 20 cows each. All cows were delivred manually 24 to 36 hours post partum and received local treatment with 1 g of oxytetracyclin. Cows in group 1 received two intra-muscular injections of 5 mg etiproston on day of manual delivery (D1) and 15 days after (D15). Cows on group II received only one etiproston administration (D1), and cows in group III remained untreated. Ratios of delayed uterine involution were respectively 20, 40 and 55 % in groupsI,II and III(I<0.05;II<0.005). PAGI concentrations were checked 15 days after parturition and were significantly higher in cows affected by delayed uterine involution (p < 0.05). V-IAF intervals were significantly (p < 0.05) different between groups I (58 days), II (102 days) and III(143 days). [less ▲]

The radiotracking of 10 serotine bats during a period of 73 nights shows that the animals hunt mainly at forest edges and above meadows. The mean distance between the main diurnal roost and hunting grounds is 2.1 +/- 1.2 km (n = 24). Secondary diurnal roosts are used within a radius of 250 m of the main diurnal quarters. Nocturnal resting places are situated in beech forests (Fagus sylvatica) near feeding areas. The activity area (minumum area method) of radiotracked serotine bats, all originating from the same colony, stretches to 15.8 km². [less ▲]

Within density-functional theory, we compute the Born effective charges of tungsten trioxyde in its reference cubic phase (defect-perovskite structure). For the tungsten atom, the effective charge tensor is isotropic, with Z(W)*=+12.51. For the oxygen atoms, the two independent components of the tensor, corresponding, respectively, to a displacement of the atom parallel or perpendicular to the W-O bond, have the values Z(O parallel to)* = -9.13 and Z(O perpendicular to)* = -1.68. Z(W)* and Z(O parallel to)* are anomalously large with respect to the nominal ionic charges (+6 on W and -2 on O), but compatible with the Born effective charges found in related ABO(3)-perovskite compounds.

BACKGROUND & AIMS: Recent studies have suggested that HLA DRB1*0103 and allele 2 of the interleukin 1 receptor antagonist (IL-1RA) gene predict severe and extensive ulcerative colitis, respectively. The aim of this study was to test these hypotheses in patients undergoing surgery for their colitis. METHODS: HLA DRB1 and DQB1 genotyping was performed in 99 patients and 472 controls. Genotyping for polymorphisms of genes encoding tumor necrosis factor alpha and IL-1RA was performed in 107 patients and 89 controls. Measurement of antineutrophil cytoplasmic antibody (ANCA) was performed in 72 patients and 58 healthy subjects by fixed neutrophil enzyme-linked immunosorbent assay and indirect immunofluorescence. RESULTS: The DRB1*0103 allele was increased in patients (14.1% vs. 3.2% in controls; P < 1 x 10[-5]). This association was greatest in patients with extensive disease (15.8%; P < 0.0001) or extraintestinal manifestations (22.8%; P < 0.0001): mouth ulcers (25.8%; P < 0.0001), arthritis (27.2%; P < 0.0001), and uveitis (35.7%; P < 0.0001). The DRB1*04 alleles were reduced in patients (P = 0.005). Differences were noted between extensive and distal disease in the frequency of allele 2 of IL-1RA (10.9% in distal vs. 28.6% in extensive; P = 0.01) and allele 2 homozygosity. ANCA was detected in 76.4% of patients. Carriage of IL-1RA allele 2 and tumor necrosis factor 2 allele was increased in ANCA-positive patients. CONCLUSIONS: Genetic markers may predict disease behavior in ulcerative colitis. [less ▲]

OBJECTIVE: Laparoscopic procedure with excision of deep fibrotic endometriotic nodules of the rectovaginal septum and histological study of the lesions. SETTING: An academic teaching hospital. PARTICIPANTS: A series of 500 women undergoing laparoscopy for pelvic pain or infertility. RESULTS: Laparoscopic (n = 497) and laparotomic (n = 3) excision of endometriotic nodules resulted in considerable pain relief. Histologically the rectovaginal nodule was similar to an adenomyoma as it was a circumscribed nodular aggregate of smooth muscle and endometrial glands and stroma. The variations in oestrogen receptor and progesterone receptor content suggested a regulatory mechanism different from that of eutopic endometrium. CONCLUSION: This form of disease should be considered as an entity distinct from peritoneal and ovarian endometriosis, and originating from the Müllerian rests present in the rectovaginal septum.
