Analysing the production and treatment of solid waste using a national accounting framework.

Our knowledge of the relationship between the economy and the environment has increased significantly over recent decades. One of the areas in which this is most apparent is the area of environmental accounting, where environmental data is presented according to national accounting principles. These accounts provide consistent, complete and detailed information for understanding environmental-economic interdependencies.

[Quality of life evaluation after total laryngectomy: interests and limits in speech therapy].

Objectives: In order to improve the speech therapy process after total laryngectomy (TL), an "ecological" approach of the rehabilitation of the TL has been used to adapt our technique to the appropriate situation of each patient (according to his expectations, his needs, etc...

Contralateral inhibition in a release from forward masking.

The current study investigated contralateral inhibition involved in a release from forward masking. The masker and probe were 1-kHz pure tones shaped by a 20-Hz modulation. Durations of the masker and probe were 500 ms and 50 ms (single cycle) respectively.

Physiological correlates of comodulation masking release in the mammalian ventral cochlear nucleus.

Comodulation masking release (CMR) enhances the detection of signals embedded in wideband, amplitude-modulated maskers. At least part of the CMR is attributable to across-frequency processing, however, the relative contribution of different stages in the auditory system to across-frequency processing is unknown. We have measured the responses of single units from one of the earliest stages in the ascending auditory pathway, the ventral cochlear nucleus, where across frequency processing may take place.

Rat gonadotropin-releasing hormone receptor expressed in insect cells induces activation of adenylyl cyclase.

Increasing evidence exist that multiple G proteins mediate the effects of gonadotropin-releasing hormone (GnRH) on the synthesis and release of pituitary gonadotropins. In the present study, we have expressed the rat GnRH receptor (GnRH-R) in insect cells, by infection with a recombinant baculovirus. Under the conditions used, insect cells expressed, 48 h post-infection, a maximum of 7800 +/- 650 receptors/cell which bound GnRH agonist [D-Trp6]GnRH with a Kd = 0.

Insect cells infected with a recombinant baculovirus express both O- and N-glycosylated forms of the rat glycoprotein hormone alpha-subunit.

Glycoprotein hormones LH, FSH, TSH and chorionic gonadotrophin are heterodimers composed of two non-covalently associated subunits, a common alpha- and a specific beta-subunit. A recombinant baculovirus containing a cDNA encoding the alpha-subunit of rat glycoprotein hormones was constructed. Viral-infected cells expressed, 48 h post infection, 7-10 mg immunoreactive alpha-glycopolypeptide/6 x 10(8) cells, of which 65-6% was able to associate with native LH beta and formed a biologically active heterodimeric hormone that bound to testicular receptors.

Modulation of regulatory and catalytic subunit levels of cAMP-dependent protein kinase A in anterior pituitary cells in response to direct activation of protein kinases A and C or after GnRH stimulation.

We have previously shown that direct activation of protein kinase A (PKA) and protein kinase C (PKC) induced changes in the expression of genes coding for PKA RII beta and C alpha subunit isoforms in cultured anterior pituitary cells, suggesting the possibility of interconnected regulation at this point. To evaluate whether the cell content of PKA protein subunits could be similarly altered, the catalytic (C) and regulatory type I (RI) and type II (RII) subunits were identified by Western blot analysis using specific immunoaffinity-purified antibodies. Activation of PKA by the permeant cyclic adenosine monophosphate (cAMP) analogue 8-Br-cAMP induced a dramatic time- and concentration-dependent decline of C subunit to a residual level that may represent 10-15% of that in untreated cells.

[Commune prison camp's health care and Versailles military hospital share].

Between June 1871 and December 1872, about five thousand prisoners were kept in Versailles among some places of detention. This high death rate was indebted for worst hygienic states (individual or collective) and food wretched quality during first weeks. Military Health Service, under Hippolyte Larrey's management with Adolphe Thiers and staff assent involved living conditions owing to tubs and toilets not forgiving accurate clothes and well-balanced food.

[The key function of the military hospital at Versaille to the army responsible for winning back Paris during the insurrection of the commune (March-May 1871)].

The military Hospital of Versailles standing near the seat of the Government and the Assemblies played an important role in the organization of the sanitary services of the Versailles army. Hippolyte Larrey, chief physician of the army decided in agreement with Thiers, head of the government that the military hospital will primarily receive all the wounded soldiers evacuated from the front lines and all the patients from the various regiments of the Versailles army. To satisfy the numerous hospitalisations, annexes were opened in Versailles, the hospital capacity being extended to 2600 beds.

[Fatigue fractures of the foot (author's transl)].

Fatigue fractures of the foot are the commonest fatigue fractures, still called walking fractures or "stress fractures". Formerly, they were metatarsal in more than 80% of cases: over the last few years, the calcaneal localizations mainly predominate (more than 70%). The fatigue fractures formerly described almost always in soldiers after a long march, are in fact encountered at all ages, including children, and in both sexes.

[Fistulography. Results of 126 examinations (author's transl)].

The authors describe the results obtained in a series of 126 patients examined by fistulography. This investigation should be conducted systematically after operative treatment of any type of fistula. The procedure involves perfusion of a water-soluble iodized contrast medium at low pressure, using a balloon sound to ensure that there are no leaks.

[Arthropneumotomography in recurrent dislocations and subluxations of the shoulder. Methods, results, and indications in 45 cases (author's transl)].

The authors describe the results of arthropneumotomography in 45 patients with recurrent dislocations or subluxations of the shoulder. The method used is given in detail and the need for excellent quality glenoid profile sections, as described by Bernageau, is emphasized. The results are analyzed for bone lesions, capsuloligamentary lesions, and intra-articular foreign bodies.

[Apophyseal detachment of the anterior iliac spines: a radiological study of three cases (author's transl)].

The authors describe 3 cases of apophyseal detachment of the anterior iliac spines. This traumatic affection occurs mainly in adolescents during sporting activities, and is a rare disorder. It has to be borne in mind when a more or less typical clinical picture is present, and the diagnosis can be made by radiological examination.

[Arthrography of the wrist: procedures and normal results (author's transl)].

The results of 31 opaque arthrographies of the wrist carried out under two different circumstances are reported. --In a first group the investigation was made immediately after or within a longer period following injury to the wrist or forearm. The results supply information to the surgeon on the condition of the triangular ligament in dislocation and partial dislocations of the inferior radioulnar joint, caused by an architectural fault in the radius after trauma (fracture of the head, diaphysis, or lower extremity).

[Partial algodystrophy].

The authors describe, on the basis of 7 cases, a special form of decalcifying algodystrophy not described in the literature, characterized by a very localized pain beginning gradually, or more often suddenly. It is of mechanical or mixed type, accompanied by local, pseudo-inflammatory signs being either apparent or discrete, very elective and very sharp pain upon palpation of a very limited area of a condyle or a tibial plate, with hyperfixation located through scintigraphy with technetium 99m polyphosphates, and regressing either spontaneously, or more quickly under treatment, of which thyrocalcitone is the essential part, without undergoing a phase of intense loco-regional demineralization. This form of algodystrophy, that they propose to call partial algodystrophy, can, like the other forms of algodystrophy, appear in monofocal or plurifocal form, either straight off or at a distance from the first incidence, which leads this new radioclinical type to be considered a simple form of algodystrophy of the limbs, midway between the types without radiological anomaly during development and the complete and extensive ones with major radiological signs.

[Pseudotumoral rheumatoid coxitis (author's transl)].

Two cases of rheumatoid coxitis of the macrogeodic type are reported. In one case, there was a very large anfractuous cavity in the socket and head, complicated by a pathological fracture of the socket, which raised the suspicion of a malignant tumor. The authors review the characteristics of these macrogeodic forms of rheumatoid arthritis, about forty cases having been reported in the published literature.
