Gli-type zinc finger proteins play important regulatory roles in vertebrate and invertebrate embryogenesis. In Xenopus, the Gli-type proteins XGli-3 and XGli-4 are first expressed in earliest stages of mesoderm and neural development. Transient transfection assays reveal that XGli-3 and XGli-4 can function as transcription repressors. Counteracting the Gli-protein repressor activity by ectopic expression of a fusion protein that contains the Gli-zinc finger cluster connected to the E1A activator domain in Xenopus embryos results in specific morphological alterations in the developing somites and in the central nervous system. Altered expression characteristics for a broad set of molecular markers highlighting specific aspects of mesodermal and neural differentiation demonstrate an important role for Gli-type zinc finger proteins in the early mesodermal and neural patterning of Xenopus embryos.

Allylselenides are efficiently oxidized by AD-mix reagents. Oxidation takes chemoselectively place on the selenium atom of allylselenides bearing a methylseleno or a phenylseleno moiety, but chemoselectively occurs on the C,C double bond of the corresponding o-nitrophenyl derivatives. [less ▲]

The risks to fauna associated with the use of pesticides are generally known for individual pesticides. There exists, however, a lack of pub Iished material providing comparative coverage of all pesticides, although some partial compilations have been published. ln an attempt to redress this situation, we propose here a Toxicity Index covering fish, birds and bees for 169 currently available insecticides.

This paper presents estimations of volume increments concerning stands of beech (Fagus silvatica) in the southern part of Belgium (Wallonie). The data upon which the study is based are issued from 429 sampling units belonging to the regional walloonian forest inventory have been remeasured at the end of a period of 10 years in order to provide estimates of a periodic annual increment in volume (to an upper limit of 22 cm in girth). Those sampling units located in public forests have been selected with respect to ecological conditions and natural regions observed in the studied area. The increment amounts 5,9 m³/ha/yr in the Ardenne and 6,8 m³/ha/yr in the Jurassic Region. The variation that has been observed ranged from 4 to 7 m³/ha/yr in Ardenne and from 5 to 8 m³ in Jurassic Region considering basal areas from 15 to 25 m²/ha. [less ▲]

Etat général du statut des vertébrés. Banalisation de la faune et altération des écosystèmes. Trois points à discuter en fonction de la conservation de la biodiversité: i) introduction d'animaux de souche étrangère (y compris pour le repeuplement des chasses et des rivières) ii) dissémination d'organismes transgéniques et iii) perte de la diversité dans la recherche : l'université connaît une dérive utilitariste ou marchande, souffre d'une tendance à l'uniformisation et perd son indépendance.
