In spring 2000, three events--two political statements by Bill Clinton and Tony Blair and a breakthrough announcement by Celera Genomics--had a major impact on biotechnology stocks. We analyze their effects over a comprehensive set of biopharmaceutical companies, using a composite return-generating model with an industry-specific patent-based factor. Our results show that stocks can be clustered according to their responsiveness to political and scientific events. Furthermore, we emphasize different impacts on the market value of intangible assets for each cluster, suggesting that growth options are valued with different criteria for therapeutics, and technology-based subsectors.

En introduisant d'épaisses suspensions microbiennes dans une quantité donnée d'actinomycétine (1*), maintenue à 2° pour éviter la bactériolyse, nous avons montré que les principes colilytique et staphylotytique (2*à 6*) peuvent être adsorbés sur les corps microbiens (7*). Escherichia coli et Micrococcus pyogenes aureus adsorbent, l'un et l'autre, ces deux agents lytiques ; mais leur capacité d'adsorption est toujours plus grande pour le principe homologue. L'adsorption est particulièrement efficace si elle est réalisée à un pH voisin de 9 et à force ionique faible. L'élution, réalisable ensuite par solution saline, permet d'obtenir les principes lytiques concentrés et, dans une certaine mesure, purifiés. Dans la présente note, le mécanisme de cette adsorption est étudié de façon plus précise, en utilisant une technique analogue à celle de la chromatographie. (1*) M. Welsch, C. R. Soc.

Pregnancy diagnosis is an important part in reproduction management of ruminants. The aim of the study was to use a new method for evaluating the bPAG and cPAG in milk and blood bPAG and compare this results with the other method for pregnancy diagnosis in the cows. The study was carried out in 220 Holstein Frisian cows. Heparinised blood samples were taken from the jugular vein and stored at -20 degrees C until PAG assay by RIA. For bPAG and cPAG, RIA test, milk samples were homogenized. Pure bPAG was used as a standard tracer described by Zoli et al. (1992). The cows were diagnosed as pregnant by means of USG (Aloka SSD 210) and by rectal palpation. bPAG and cPAG concentration in milk increased after 28 day of pregnancy and showed the rapid increase near the parturition. The same results of bPAG concentration we obtained in the blood samples. The decline of bPAG concentration was faster in the milk than in the blood. The data showed that the RIA method is precise enough to measure PAG concentrations in the maternal blood and milk of cows. The data indicate that milk samples can be used for pregnancy diagnosis in cows. The sensitivity and specificity of RIA measurement of PAG are very high. [less ▲]

The concentration of telluric carbon monoxide has been determined in the upper stratosphere from infrared solar spectra recorded by balloon on October 1978 and September 1979, over Texas, USA. The average mixing ratios were found to be (2.1∓.3)×10−8ppv and (3.7∓.4)×10−8ppv above the float altitudes of 30.6 and 36.8 km, respectively. The concentration profile deduced from all our measurements indicates that the CO mixing ratio increases in the upper stratosphere, from (1∓.3)×10−8ppv at 30.6 km, to about 4×10−8ppv above 41 km.

Seven polybrominated diphenyl ether (PBDE) congeners were measured in the particulate fraction (<2mm) of household dust samples (n=40), collected in four different countries (Australia, Germany, Great Britain, and United States). Dust samples from Germany contained the lowest concentrations of total PBDEs (median: 74 ng/g, range: 17-550 ng/g dust). Australian dust contained the second lowest concentration (median: 1200 ng/g, range: 500-13,000 ng/g dust). The dust from the United States and Great Britain contained the highest measured amounts of total PBDEs (US median: 4200 ng/g dust, range: 520-29,000 ng/g; Great Britain median: 10,000 ng/g, range: 950-54,000 ng/g). Daily intake of PBDEs has been estimated from published reference values on daily dust intake rates. The highest daily intake of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) found was in the United States (<1-330 ng/day) and the lowest was in Germany (<1-2 ng/day). The PBDE congeners present in commercially available pentabromodiphenyl ether were the highest in concentration in the United States, and the congener distribution was similar to that of the technical preparation (i.e., 2,2',4,4',5-pentabromodiphenyl ether [BDE-99] was similar in concentration to that of BDE-47). We conclude that further studies are required to investigate human indoor exposure to PBDEs across countries and to determine the risk factors related to indoor design factors. [less ▲]

Myeloperoxidase (MPO) is a pro-oxidant enzyme associated with decreased motility in thawed equine semen. This study aimed to describe MPO concentration, activity and subunits in raw and thawed semen and to correlate these data with motilities in raw and thawed semen. Semen samples from five stallions were collected four times. Motilities were assessed in raw and thawed semen. MPO assays were performed in raw seminal plasma, raw sperm-rich pellet and thawed semen. Total and active MPO concentrations were, respectively, assayed by enzyme-linked immunosorbent assay and specific immunological extraction followed by enzymatic detection. MPO subunits present in semen were characterized by Western 3 blot. Purified active MPO was added in PBS and freezing extender to control its activity during freezing procedure. Differences between medians were determined using Kruskal– Wallis test, and correlations were determined using Spearman’s test for nonparametric data. Active MPO concentration was low in seminal plasma and thawed semen, but high in pellet (p = 0.0058), as the opposite relation was observed for total MPO concentration (p < 0.0001). In seminal plasma and post- thaw semen, inactive 86-kDa MPO precursor was mainly observed. Purified MPO activity was decreased in the extender (p = 0.0286). MPO activity in pellet was highly correlated with thawed progressive motility (r = 􏰑0.5576, p = 0.0086). Inac- tive MPO precursor and unknown low molecular weight inactive MPO precursor subunits explain low MPO activity in semen. Major MPO activity was observed in pellet, and post- thaw loss of activity is partially explained by MPO inactiva- tion in extender. Thawed semen motility was negatively correlated with MPO activity in pellet, becoming a potential freezability predictor. [less ▲]
