Objectives: connective tissues constitutive of skin and bones are affected during the climacteric. Hormone replacement therapy (HRT) can help mitigate their atrophy. The aim of this study was to compare the HRT effect on the skin tensile properties and bone mass density. Methods: a total of 120 postmenopausal women (60 untreated, 60 receiving HRT) were enrolled in the study. Skin tensile properties were assessed on the volar forearm using a computerized suction device. A 500 mbar suction was applied through a 4-mm diameter hollow probe. Two operating modes were applied using a steep and a progressive Suction, respectively. BMD was measured on the hip, femoral neck and lumbar spine using dual X-ray absorptiometry. Results: in both groups of women skin elasticity was correlated with BMD. HRT significantly reduced the climacteric-associated decline in skin elasticity. A trend in better preserved BMD was also found in these women without, however, reaching significance. Conclusions: it is concluded that measures of the skin tensile properties can be sensitive enough to disclose HRT efficacy upon connective tissue atrophy. Any decrease in skin elasticity during the climacteric should prompt to perform a BMD assessment. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved. [less ▲]

BACKGROUND: There is ample evidence that the skin barrier function is altered in atopic dermatitis. Little information is available about the effect of topical corticosteroids and calcineurin inhibitors on this function. PURPOSE: To assess the water content and its rate of accumulation in the stratum corneum of atopic patients using an indirect electrometric method while on tacrolimus or betamethasone valerate treatment. METHOD: Twenty-one patients with moderate atopic dermatitis affecting both forearms completed this double-blind randomized study. One forearm was treated twice daily for 3 weeks with 0.1% tacrolimus ointment. The other forearm was similarly treated with 0.12% betamethasone valerate ointment. Electrometric measurements were made under continuous occlusion secured by a Nova Dermal Phase Meter sensor probe. Assessments were performed at inclusion, after the 3-week treatment and after a further 3-week follow-up out of treatment. RESULTS: During treatment, both compounds yielded a similar improvement in skin barrier function. Indeed, under probe occlusion, the rate of water accumulation was significantly decreased. This improvement was sustained after stopping the tacrolimus treatment. By contrast, the benefit was in part lost at the site that had been treated by betamethasone valerate. CONCLUSION: The difference in the effect of the 2 compounds may be due to the negative influence of betamethasone valerate on the epidermal metabolism leading to progressive atrophy of the tissue. The better preservation of the skin barrier function after stopping tacrolimus treatment may help retarding relapses of atopic dermatitis. [less ▲]

Background: Currently, about 400 million hectares of tropical moist forests worldwide are designated production forests, about a quarter of which are managed by rural communities and indigenous peoples. There has been a gradual impoverishment of forest resources inside selectively logged forests in which the volume of timber extracted over the first cutting cycle was mostly from large, old trees that matured over a century or more and grew in the absence of strong anthropological pressures. In forests now being logged for a second and third time, that volume has not been reconstituted due in part to the lack of implementation of post-logging silvicultural treatments. This depletion of timber stocks renders the degraded forests prone to conversion to other land uses. Although it is essential to preserve undisturbed primary forests through the creation of protected areas, these areas alone will not be able to ensure the conservation of all species on a pan-tropical scale, for social, economic and political reasons. The conservation of tropical forests of tomorrow will mostly take place within human-modified (logged, domesticated) forests. In this context, silvicultural interventions are considered by many tropical foresters and forest ecologists as tools capable of effectively conserving tropical forest biodiversity and ecosystem services while stimulating forest production. This systematic review aims to assess past and current evidence of the impact of silviculture on tropical forests and to identify silvicultural practices appropriate for the current conditions in the forests and forestry sectors of the Congo Basin, Amazonia and Southeast Asia. Methods: This systematic review will undertake an extensive search of literature to assess the relative effectiveness of different silvicultural interventions on timber production and the conservation value of forests, and to determine whether there is a relationship between sustainability of timber harvesting and the maintenance/conservation of other ecosystem services and biodiversity in production forests. Data will be extracted for meta-analysis of at least sub-sets of the review questions. Findings are expected to help inform policy and develop evidence-based practice guidelines on silvicultural practices in tropical forests. [less ▲]

There is some evidence that the chemical composition and nutritional value of corn is variable and may be influenced by heat treatment. This study compares the modifications induced by freeze-drying (as control), fluidized-bed drying and heat-moisture treatment (at 54, 90 and 130°C) of a flint corn grain and flour harvested at two different moisture content (33 and 28%, wet basis) on its digestibility assessed through in vitro methodologies. High temperature applied during fluidized-bed drying and heat-moisture treatment lead to the increase of the in vitro digestibility of dry matter. This is associated to a partial gelatinization of corn starch granules during heat treatments making them more suitable for digestion by porcine pancreatic amylase. This assumption is demonstrated by the increase of the in vitro digestibility of starch recorded with the increase of drying and heat-treatment temperature. It must be noted however, that at the same time, the digestibility of corn proteins decreased, probably because of denaturation undergo by proteins during heat treatment. It seems that there is an interaction between digestion of starch and protein, the corn starch granule being tightly embedded in a protein matrix. The extent of all of these phenomena strongly depends on availability of water which play a key but non clear role in the effect thermal history of corn grain in its nutritive value. [less ▲]

OBJECTIVE: To compare the effects of hydrogen peroxide (H(2)O(2)) to those of interleukin-1beta (IL-1beta) on gene expression in juvenile bovine articular chondrocytes (BAC). The study analyses the activation of nuclear factor-kappa B (NF-kappaB) and activator protein-1 (AP-1) transcription factors, and the mRNA steady-state levels of the type II collagen, aggrecan core protein matrix, metalloproteinases (MMP-1, -3), and transforming growth factor-beta1 (TGF-beta1) genes. METHODS: Confluent BAC cultures were treated for 3 and 24h with IL-1beta and/or different concentrations of H(2)O(2) (Protocol 1). Following initial treatment, a part of the cells was further subjected to another 24h with medium, in the presence of IL-1beta, to determine the effect of the cytokine on H(2)O(2) pre-treated cells (Protocol 2). Total RNA and nuclear protein extractions were performed to study mRNA steady-state levels (real-time polymerase chain reaction) and AP-1/NF-kappaB DNA binding (Electrophoretic Mobility Shift Assays), respectively. RESULTS: IL-1beta enhanced both AP-1 and NF-kappaB binding, whereas H(2)O(2) only activated AP-1. H(2)O(2) pre-treatment decreased the IL-1beta activation of NF-kappaB. Both H(2)O(2) and IL-1beta down-regulated type II collagen and aggrecan expression and increased that of MMP-1 and -3. When cells were pre-treated with H(2)O(2), followed by IL-1beta, the effects were the same as those observed with H(2)O(2) alone. However, although H(2)O(2) and IL-1beta were capable of increasing TGF-beta1 expression separately, subsequent incubation with both factors led to a partial or total abolition of TGF-beta1 up-regulation. CONCLUSION: The different regulation of NF-kappaB and AP-1 by H(2)O(2) and IL-1beta underlines the distinct roles played by the two transcription factors in the regulation of gene expression. H(2)O(2) and IL-1beta exert similar effects on matrix, MMPs and TGF-beta1 gene expression. However, the association of H(2)O(2) and IL-1beta does not cause synergic effect, and rather leads, in some cases, to an opposite effect. These data provide further insights into the respective roles of reactive oxygen species and cytokine in the pathophysiology of joint diseases. [less ▲]

BACKGROUND: The Bispectral Index (BIS) and spectral entropy of the electroencephalogram can be used to assess the depth of hypnosis. Ketamine is known to increase BIS in anaesthetized patients and may confound that index as a guide to steer administration of hypnotics. We compared the effects of ketamine on BIS, response entropy (RE) and state entropy (SE) during surgery under sevoflurane anaesthesia. METHODS: Twenty-two women undergoing gynaecological surgery were enrolled in this double-blind, randomized study. Anaesthesia was induced i.v. and maintained with sevoflurane. Under stable surgical and anaesthetic conditions, patients were assigned to receive either a bolus of ketamine 0.5 mg kg(-1) or the same volume of saline. Blood pressure, heart rate, BIS, RE and SE were measured every 2.5 min from 10 min before (baseline) until 15 min after ketamine or saline administration. The maximum relative increase in BIS, RE and SE compared with baseline was calculated for each patient. Values are mean (sd). RESULTS: Baseline values were BIS 33 (4), RE 31 (5), SE 30 (5) for the ketamine patients and BIS 35 (3), RE 33 (5) and SE 32 (6) for the patients receiving saline. BIS, RE and SE increased significantly from 5 min (BIS) and 2.5 min (RE and SE) after ketamine administration, peaking at 46 (8) (BIS), 52 (12) (RE) and 50 (12) (SE) respectively. The maximum relative increase in RE [42.2 (10.4%)] and SE [41.6 (10.9)%] was higher than that of BIS [29.4 (10.4%)]. Blood pressure, heart rate and RE-SE gradient did not change in either group. CONCLUSIONS: Ketamine administered under sevoflurane anaesthesia causes a significant increase in BIS, RE and SE without modification of the RE-SE gradient. This increase is paradoxical in that it is associated with a deepening level of hypnosis. [less ▲]

BACKGROUND: The aim of this study was to compare the effects of Euro-Collins and University of Wisconsin solutions on pulmonary mitochondrial function after cold ischemia and subsequent warm reperfusion. METHODS: Seventeen pigs underwent lung harvesting after classical lung flush with either University of Wisconsin or Euro-Collins solutions. The mitochondria were isolated from fresh swine lungs, from swine lungs subjected to 24 hr of cold ischemia, and from swine lungs subjected to 24 hr of ischemia followed by 30 min of subsequent ex vivo reperfusion at 37 degrees C with Krebs-Henseleit buffer solution and air ventilation. Mitochondrial oxidative phosphorylation parameters were determined in isolated mitochondria by in vitro measurement of oxygen consumption rates. During reperfusion, the lung function was assessed by the pulmonary aerodynamic parameters and the pulmonary vascular resistance. RESULTS: Relative to controls, mitochondria submitted to cold ischemia showed an alteration in the oxidoreductase activities of the respiratory chain. However, the yield of oxidative phosphorylation was conserved. After reperfusion, pulmonary mitochondria underwent a significant worsening in the oxidoreductase activities of the respiratory chain, and a decrease in the respiratory control and the efficiency of oxidative phosphorylation. Meanwhile, the reperfused lungs showed evidence of early dysfunction, assessed by the aerodynamic parameters and pulmonary vascular resistance. In this model, there was no advantage of University of Wisconsin solution over Euro-Collins solution. CONCLUSIONS: The mild mitochondrial alterations after cold ischemia were not sufficient to explain the limited tolerance of lung to ischemia. After reperfusion, the mitochondrial damage was more severe and could be involved in the posttransplant lung dysfunction. [less ▲]

Objective.-To confirm the efficacy advantage of eletriptan 40 mg over sumatriptan 100 mg. Background.-Eletriptan 80 mg has demonstrated significantly greater efficacy when compared to both sumatriptan 50 mg and 100 mg in two studies. Eletriptan 40 mg demonstrated significantly greater efficacy than sumatriptan 100 mg in one previous trial. Methods.-Two thousand one hundred thirteen patients with a diagnosis of migraine according to International Headache Society criteria were randomized using a double-blind, double-dummy, parallel-group design, and treated for a single migraine attack with either eletriptan 40 mg, sumatriptan 100 mg, or placebo. The primary endpoint was 2-hour headache response. Secondary endpoints included headache response rates at 1 hour, pain-free rates, absence of associated symptoms, functional response at 1 and 2 hours, and sustained headache response. Results.-Headache response rates at 2 hours postdose were significantly higher for eletriptan 40 mg (67%) than for sumatriptan 100 mg (59%; P<.001) and placebo (26%; P <.0001). Eletriptan 40 mg consistently showed significant (P<.01) efficacy over sumatriptan 100 mg across secondary clinical outcomes, including 1-hour headache response; 2-hour pain-free response; absence of nausea, photophobia, and phonophobia; functional improvement; use of rescue medication; treatment acceptability; and sustained headache response (P<.05). Overall, treatment-related adverse events were low, nausea being the only adverse event with an incidence of 2% or higher (4.9% with eletriptan, 4.2% sumatriptan, 2.8% placebo). Conclusion.-This trial confirmed that eletriptan 40 mg offers superior efficacy in treating migraine pain and associated symptoms and in restoring patient functioning when compared with sumatriptan 100 mg.

Eletriptan 40 mg and 80 mg have shown greater efficacy in acute migraine than oral sumtriptan 100 mg and naratriptan 2.5 mg. This study continues the systematic series of active comparator trials in the eletriptan clinical development programme. In a multicentre double-blind, double-dummy, parallel-groups trial, 1587 outpatients with migraine by IHS criteria were randomised in a 3: 3: 3: 1 ratio to eletriptan 80 mg, eletriptan 40 mg, zolmitriptan 2.5 mg or placebo. Of these, 1312 treated a single migraine attack and recorded baseline and outcome data to be included in the intention-to-treat population. The primary analysis was between eletriptan 80 mg and zolmitriptan. For the primary efficacy end-point of 2-h headache response, rates were 74% on eletriptan 80 mg, 64% on eletriptan 40 mg, 60% on zolmitriptan (P < 0.0001 vs. eletriptan 80 mg) and 22% on placebo (P < 0.0001 vs. all active treatments). Eletriptan 80 mg was superior to zolmitriptan on all secondary end-points at 1, 2 and 24 h, in most cases with statistical significance. Eletriptan 40 mg had similar efficacy to zolmitriptan 2.5 mg in earlier end-points, and significantly (P < 0.05) lower recurrence rate and need for rescue medication over 24 h. All treatments were well tolerated; 30-42% of patients on active treatments and 40% on placebo reported all-causality adverse events that were mostly mild and transient. On patients' global ratings of treatment, both eletriptan doses scored significantly better than zolmitriptan. [less ▲]
