From the first 198 patient files included into the French Acromegaly Registry, we analyzed 68 patients harboring a somatotroph adenoma with extrasellar extension, after exclusion of those treated by stereotactic or conventional radiotherapy. In these patients (including 37 women), aged 21-77 yr. (45.7 +/- 13.3), GH concentrations ranged from 2-260 microg/L (38.6 +/- 44.3), and IGF I from 86-967% of age-matched upper limit of normal (303 +/- 164). Maximal diameter of the adenoma at MRI was 11-36.5 mm (20.4 +/- 6.5), with cavernous sinus involvement in 68% of cases. Three subgroups were defined: 20 patients treated by long-acting somatostatin analogs only (group M), for a mean duration of 3 yr. (extremes 1-7 yr.), 48 patients initially treated by transsphenoidal surgery (group C), of whom 21 were secondarily treated by long-acting somatostatin analogs (group CM) for a mean duration of 1.2 yr. (extremes 0.2-2 yr.). All 3 groups were not statistically different in terms of tumor mass and initial levels of GH and IGF-1. Patients from group M were significantly older than those of the other groups (p<0.05). RESULTS: 46% of patients from group C after surgery vs. 45% of patients from group M had a mean GH below 2.5 microg/L. Biochemical remission (GH<2.5 microg/L and normal IGF1 normal) was obtained in 31% of cases in group C, vs. 25% in group M. In this group, a decrease of the largest tumor diameter was observed in 10 patients (71.5%), ranging from 10-25% in 7 (50%) and exceeded 50% in 3 (21.5%). In group CM, the biochemical remission rate (42%) and final GH or IGF1 values were not significantly different from group M. In conclusion, these data suggest that surgery or long-acting somatostatin analogs have a comparable efficacy in terms of remission rates in somatotroph macroadenomas with extrasellar extensions.

The paper proposes two numerical models ot the mechanical behaviour of chalk. First, an elasto-plastic constitutive law reproduces the different plastic mechanisms of the chalk and the influence of pore fluids by introducing the concept of suction. Secondly, a model able to reproduce time dependence behaviour. Eventually, the paper gives a simulation of an academic reservoir during depletion and waterflooding phase. [less ▲]

Several species of Doryphorina leaf beetles from Central- and South America produce oleanane triterpene glycosides in their defensive glands. The presence of pentacyclic triterpenes in insects is intriguing since they lack the key enzymes necessary to synthesize these compounds. Since beta-amyrin is a common constituent of leaf waxes, we hypothesized that these leaf beetles use this compound as a precursor to their oleanane glycosides. To test this hypothesis we first confirmed the presence of beta-amyrin in Ipomoea batatas, the food plant of Platyphora kollari. Next, adults of P. kollari were fed for 10 days with I. batatas leaf disks painted with a solution of [2,2,3-H-2(3)]beta-amyrin ([2,2,3-H-2(3)]-1). The secretion from their defensive glands was collected and analyzed by HPLC-ESIMS. The results demonstrated that the secretion of beetles fed with an amount of [2,2,3-H-2(3)]beta-amyrin corresponding to the quantity of unlabeled (natural) beta-amyrin present in the leaf disks contained on average 5.1% of [2,2,3-H-2(3)]-3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucuronopyranosyl-hederagenin ([2,2,3-H-2(3)]-2), whereas the secretions of beetles fed with 10 times this amount of [2,2,3-H-2(3)]beta-amyrin contained on average 23.9% of [2,2,3-H-2(3)]-2. In both series of experiments, the percentage of labeled versus unlabeled triterpene glycoside in the secretion was positively correlated with the amount of deuterated beta-amyrin ingested. These results demonstrate for the first time that some leaf beetles are able to metabolize a widespread triterpenic constituent of leaf wax into more complex glycosides that are stored in their defensive glands.

The poplar wood has been known and used for a very long time. However, it has been systematically studied only since the end of the second world war, probably because of its reduced presence in the forests. An intuitive use of the poplar existed already among our ancestors but the study of its macro- and microscopic properties has directed it to more specific uses. The comprehension of its physical and mechanical properties led to a better knowledge of its behaviour during the various phases of transformation and helped to forecast its evolution when used, taking into account its natural longevity and the eventual presence of defects appearing on the trees and in the wood. In current poplar cultivation, all these characteristics must be considered to fix the criteria of selection taking into account the quality of the wood and its capability for transformation. The clonal production of poplars offers the transformation industry a raw material relatively homogenous in terms of technological properties, form and dimension. Nevertheless, each cultivar can differ in one or several of its characteristics. [less ▲]
