The effect of LiCl on the stereochemistry of the anionic polymerization of methyl methacrylate in the presence of a lithium counterion at -78-degrees-C in THF and in a 9/1 toluene/THF mixture, has been studied by C-13 and H-1 NMR spectroscopy. It has been found that LiCl has an important effect on the E/Z ratio of the living chain ends in THF, in contrast to the main-chain tacticity. In contrast, LiCl has a significant influence on the stereoregularity of the anionic polymerization of MMA in a 9/1 toluene/THF mixture. When the LiCl/initiator molar ratio is increased, the syndiotactic placements (rr) are favored at the expense of the isotactic ones (mm). This effect can be accounted for by a multistate propagating mechanism controlled by association/complexation equilibria among associated, nonassociated, and LiCl-complexed species. These association/complexation equilbria, which were originally proposed by Muller, appear to have a decisive effect not only on the livingness (molecular weight distribution (MWD)) but also on the stereochemistry of the anionic polymerization of MMA in a 9/1 toluene/THF mixture at -78-degrees-C, confirming the involvement of the ligand in propagation control.

High spatial resolution images of the north polar region of Jupiter have been obtained with the Faint Object Camera (FOC) on board the Hubble Space Telescope (HST). The first set of two images collected 87 min apart in February 1992 shows a bright (approximately or equal to 180 kR) emission superimposed on the background in rotation with the planet. Both Ly alpha images show common regions of enhanced emission but differences are also observed, possibly due to temporal variations. The second group of images obtained on June 23 and 26, 1992 isolates a spectral region near 153 nm dominated by the H2 Lyman bands and continuum. Both pictures exhibit a narrow arc structure fitting the L = 30 magnetotail field line footprint in the morning sector and a broader diffuse aurora in the afternoon. They show no indication of an evening twilight enhancement. Although the central meridian longitudes were similar, significant differences are seen in the two exposures, especially in the region of diffuse emission, and interpreted as signatures of temporal variations. The total power radiated in the H2 bands is approximately or equal to 2 x 10[SUP]12[/SUP] W, in agreement with previous UV spectrometer observations. The high local H2 emission rates (approximately 450 kR) imply a particle precipitation carrying an energy flux of about 5 x 10[SUP]-2[/SUP] W/sq m. [less ▲]

The interactions between imipenem and four monobactams and three class A beta-lactamases have been studied in detail. Despite their reputation as being beta-lactamase-stable, some of these compounds were significantly hydrolysed by the enzymes. The results obtained with the Streptomyces albus G beta-lactamase have been analysed in the light of molecular modelling studies. The discussion is extended to include other so-called beta-lactamase-stable antibiotics to demonstrate that this appellation can often be misleading. [less ▲]

A loss of the continuous linear deposit of basement membrane around invasive carcinomas has been suggested to correlate with their increased invasiveness. In contrast, extensive basement membrane deposition would represent a more favourable prognosis. The Engelbreth-Holm-Swarm (EHS) tumour, a transplantable neoplasm, is widely used for its ability to synthesize and deposit large amounts of basement membrane components. We have evaluated the metastatic potential of this neoplasm 2 months after subcutaneous inoculation. Histological examination of lung sections revealed the presence of numerous metastatic foci. The metastatic cells retained their organization into clusters surrounded by extracellular matrix. Both the 72 kDa and the 92 kDa type IV collagenases were detected by zymography in Triton or urea extract (matrigel) of primary tumour. These results cast doubt on the hypothesis that the extensiveness of basement membrane deposition might always be of prognostic value by being inversely correlated with the degree of invasiveness of a carcinoma.

Histamine is an important mediator of allergic inflammation and bronchial hyperresponsiveness (BHR), a hallmark of asthma. Studies on the relationship between plasma histamine and BHR in allergic asthmatic patients have yielded controversial results. We therefore measured plasma histamine and bronchial reactivity in 30 nonsmoker volunteers taking no medication. Eleven were normal subjects; 19 were stable, mildly allergic asthmatic patients. Venous blood was taken to measure blood cells and basal plasma histamine by radioimmunoassay. After blood sampling, all subjects underwent a measurement of PC20M (concentration of methacholine causing a 20% fall in FEV1). Mean plasma histamine levels were 0.21 +/- 0.1 ng/ml and 0.44 +/- 0.3 ng/ml in normal and asthmatic subjects, respectively (P < 0.05). We found a significant increase of blood eosinophils and basophils in asthmatic patients, and a positive correlation between plasma histamine and circulating basophils. PC20M was greater than 16 mg in normal volunteers, and mean PC20M was 2.1 +/- 2 mg/ml in asthmatic patients. PC20M did not correlate with plasma histamine levels, but it did so negatively with blood eosinophils. The increased plasma histamine concentration in mildly atopic asthmatic patients might be a consequence of the high basophil releasability of atopics and the higher basophil counts in allergic asthma. Plasma histamine is thus unlikely to be a determinant of BHR in asthma. [less ▲]
