The authors report the detection of interstellar CH and CH[SUP]+[/SUP] towards supernova 1987A. For both of these molecules, one component is detected at a heliocentric velocity of about 280 km/s, corresponding to material inside the LMC. Some implications of the authors' results with regards to the H[SUB]2[/SUB]-to-dust ratio are briefly discussed. [less ▲]

Analysis of new and already published photometric observations shows that the Wolf-Rayet star WR 16 = HD 86161 is not a binary system (WR + compact, P = 5.365 d) as claimed by Moffat and Niemela (1982). Instead it is shown that the simultaneous presence of two periodicities (about 1.3 and 2.5 days) is necessary to account for the observed variations during at least one observing run. The variability of the B9p star HD 86199, previously used as a comparison for a photometric study of WR 16, is established. [less ▲]

A 19 kb SphI DNA fragment containing the gene for the extracellular active-site serine beta-lactamase of Streptomyces cacaoi KCC-SO352 was cloned in Streptomyces lividans TK24 using the high-copy-number plasmid pIJ702 as vector. A 30-fold higher yield of beta-lactamase was obtained from S. lividans strain ML1, carrying the recombinant plasmid pDML51, than from S. cacaoi grown under optimal production conditions. In all respects (molecular mass, isoelectric point, kinetics of inhibition by beta-iodopenicillanate) the overproduced S. lividans ML1 beta-lactamase was identical to the original S. cacaoi enzyme. A considerable reduction of beta-lactamase production was caused by elimination of a 12.8 kb portion of the 19 kb DNA fragment by cleavage at an internal SphI site located more than 3 kb upstream of the beta-lactamase structural gene. The beta-lactamase gene was located within a 1.8 NcoI-BclI fragment but when this fragment was cloned in S. lividans pIJ702, the resulting strain produced hardly any more beta-lactamase than the original S. cacaoi.

The purpose of this study was to estimate the effects of intense and regular physical activity on locomotor system modifications. Tennis, with its unilateral solicitations, allows a more precise examination of specific localized development. Ten professional tennis players were compared with sedentary age-matched students. Muscular modifications were observed, mainly in the forearm circumference. The dominant side forearm circumference was 13% larger than the opposite side. Asymmetry was less in the upper arm and insignificant in the thorax and vertebra. Deep modifications in bone mineral content (BMC) were investigated by isotopic techniques, based on differential photon attenuation in bone and soft tissue of the forearm. Bone density was markedly increased in professional tennis players. Even in the nondominant side, radius BMC was 1.18 g HA/cm, 15% higher than in sedentary control students. The difference was yet larger in the dominant mid-radius, reaching 1.47 g HA/cm. The same differences were observed for the ulna and involved both cortical and trabecular bone. In the control group of sedentary students, no significant difference was noted between the two upper limbs. This study clearly demonstrates the positive correlation between exercise and bone mineralization. The precise mechanical constraints optimizing the favorable effect in the most efficient way should be studied. [less ▲]

We describe a very sensitive and precise assay which allows one to study the metabolism of testosterone (T) in small brain nuclei dissected out according to the method of Palkovits and Brownstein. With this method, the neuroanatomical distributions of aromatase, and 5 alpha- and 5 beta-reductase activities were studied in adult male quail (Coturnix coturnix japonica). The different enzymes show different neuroanatomical distributions. Production of estradiol-17 beta (E2) was highest in the sexually dimorphic nucleus preopticus medialis (POM). We showed previously that the preoptic aromatase activity is higher in male than in female quail. As the POM is a central and very large structure within the preoptic area, the present results suggest a relationship between the neuroanatomical and the biochemical sex differences. By contrast, the production of 5 alpha-DHT was highest in the lateral hypothalamic area (LHY), the bed nucleus of the pallial commissure (BPC) and the lateral septum (SL). The 5 beta-reductase activity was highest in the lateral septum and in the ventral part of the archistriatum (AV). Moreover, there was a rostral to caudal decrease in 5 beta-reductase activity in the hypothalamus. [less ▲]

An in vitro radioenzymatic assay and purification procedure by thin-layer chromatography were used to study the metabolism of dihydrotestosterone (DHT) into 3 alpha- and 3 beta-androstanediols by the brain and cloacal gland of Japanese quail. Kinetic studies showed that these 2 metabolites are produced in a linear fashion with respect to time of incubation for up to 15 min but that they continue to accumulate for up to 4 h. The maximum velocity of these reactions is high (nmol/mg protein/15 min), but the affinities of the enzymes for DHT are low (in the microM range). The enzymatic activities are not evenly distributed in the brain: they are high in the tuberal hypothalamus and lobus parolfactorius but low in the preoptic area and anterior hypothalamus. Enzyme activities are not markedly affected by treatment of the birds with either testosterone or DHT. The activity of these enzymes is lower in the preoptic area and tuberal hypothalamus of DHT-treated birds which display female-directed sexual behavior than in the same brain areas of birds which are sexually inactive. We discuss the relationships between this reductive metabolism of DHT and the activational effects of the steroid on sexual behavior. [less ▲]
