In agriculture, the concept of sustainable development emergence and its omnipresence in political discourses suggests that farming systems move toward systems considered as more environment-friendly and human health-friendly. In Benin, cotton is one of the most sectors concerned by this transformation. Indeed, in spite of the importance of cotton in the economy of Benin, its sustainable production is nowadays threatened by conventional production approach. Various alternatives of production are developed and considered as more environment-friendly than the conventional production approach. This article analyses the sustainability of the organic and cotton made in Africa (CmiA) farming alternatives from the sustainable agricultural intensification theoretical perspective. Structured and non-structured interviews with individuals and focus groups were used to collect data from 90 organic cotton farmers of the municipality of Kandi, and 100 CmiA farmers of the municipality of Pehunco, one of the largest areas of cotton production in the North of Benin. Data were analyzed with methods of normative and relativist comparison, descriptive statistics and analysis of variance. Kolmogorov-Smirnov (K-S) test was used to verify the normality conditions and in some cases, logarithmic transformation was done to test the variance homogeneity. The comparison of means was done with the test of Least Significant Difference. It appears from the results that in the current condition of implementation, the alternatives system to conventional cotton production approach are not intensively sustainable. Soils fertility and pests’ management face enormous constraints and do not allow improvement of yields, economic performances, and environment protection. So, the sustainability of the alternative systems of cotton production is not guaranteed and can hardly become a reality if additional relevant conditions are not created. [less ▲]

This paper clarifies the path that Rwanda took in the quest for a modern, intensive, productive and market-oriented agriculture. The facts presented here have been collected by means of documentation that led to the review of different publications including published papers and government and development partners’ reports. The paper shows that an adequate policy and institutional environment has been created by various socio-economic, institutional and agriculture-led reforms launched since the early 2000s. The literature review reveals that impressive results have been recorded in regard to smallholder agriculture intensification. In addition, the theoretical model for progressive smallholder agriculture transformation helped to show that most of the smallholders grouped in cooperatives are at the 'semi-commercial smallholders' stage while only a few are at the 'commercial smallholders' and 'advanced farmers' stages. This study also examines various challenges that hamper the sustainable intensification of smallholder agriculture at both institutional, community and smallholder level. It suggests some policy actions to be put forward by the government and other agriculture sector development partners to address those challenges. [less ▲]

Background The outcome of diff use large B-cell lymphoma has been substantially improved by the addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy regimens. We aimed to assess, in patients aged 18–59 years, the potential survival benefi t provided by a dose-intensive immunochemotherapy regimen plus rituximab compared with standard treatment plus rituximab. Methods We did an open-label randomised trial comparing dose-intensive rituximab, doxorubicin, cyclo phosphamide, vindesine, bleomycin, and prednisone (R-ACVBP) with subsequent consolidation versus standard rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisone (R-CHOP). Random assignment was done with a computer-assisted randomisation-allocation sequence with a block size of four. Patients were aged 18–59 years with untreated diff use large B-cell lymphoma and an age-adjusted international prognostic index equal to 1. Our primary endpoint was event-free survival. Our analyses of effi cacy and safety were of the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT00140595. Findings One patient withdrew consent before treatment and 54 did not complete treatment. After a median follow-up of 44 months, our 3-year estimate of event-free survival was 81% (95% CI 75–86) in the R-ACVBP group and 67% (59–73) in the R-CHOP group (hazard ratio [HR] 0·56, 95% CI 0·38–0·83; p=0·0035). 3-year estimates of progression-free survival (87% [95% CI, 81–91] vs 73% [66–79]; HR 0·48 [0·30–0·76]; p=0·0015) and overall survival (92% [87–95] vs 84% [77–89]; HR 0·44 [0·28–0·81]; p=0·0071) were also increased in the R-ACVBP group. 82 (42%) of 196 patients in the R-ACVBP group experienced a serious adverse event compared with 28 (15%) of 183 in the R-CHOP group. Grade 3–4 haematological toxic eff ects were more common in the R-ACVBP group, with a higher proportion of patients experiencing a febrile neutropenic episode (38% [75 of 196] vs 9% [16 of 183]). Interpretation Compared with standard R-CHOP, inten sifi ed immunochemotherapy with R-ACVBP signifi cantly improves survival of patients aged 18–59 years with diff use large B-cell lymphoma with low-intermediate risk according to the International Prognostic Index. Haematological toxic eff ects of the intensive regimen were raised but manageable. Funding Groupe d’Etudes des Lymphomes de l’Adulte and Amgen. [less ▲]

BACKGROUND: Late graft rejection after conditioning with 1 Gy of total body irradiation (TBI) was consistently seen in historical dogs given two postgrafting immunosuppressive drugs. METHODS: Here, 16 dogs were given four different three-drug combinations of cyclosporine, mycophenolate mofetil, sirolimus, or methotrexate after 1 Gy TBI and dog leukocyte antigen-identical marrow grafts. In addition, we assessed the effects of TBI doses of 0.5, 1.0, 2.0, or 3.0 Gy, respectively, on immune functions in six dogs not given marrow grafts. RESULTS: All dogs showed initial engraftment, 13 rejected, and three had sustained grafts beyond 26 weeks. The dogs with durable grafts had received greater median numbers of nucleated marrow cells compared with the 13 dogs that rejected their grafts (6.14 vs. 3.6 x 10(8) per kg; P=0.03). In a Cox proportional hazard model, which included data from 16 historical dogs, each increase in transplanted marrow cell numbers by 1 x 10(8) per kg decreased the hazard ratio of rejection by 0.5. Decreasing percents of remaining CD3, CD4, and CD8 cells in peripheral blood and lymph nodes were observed with increasing TBI doses. Further, greater suppressions of B-cell- and T-cell-dependent production of IgM and IgG antibodies in response to sheep red blood cell injections were observed after 2 Gy compared with 1 Gy TBI. CONCLUSION: Overall, triple postgrafting immunosuppression after 1 Gy TBI was well tolerated but failed to prevent graft rejection in this model. In vivo radiation studies have shown higher numbers of remaining host lymphocytes and better T-cell-dependent antibody production after 1 Gy compared with 2 Gy TBI. [less ▲]

Migraine patients show interictally a strong intensity dependence of auditory evoked cortical potentials (IDAP) and a lack of habituation of evoked potentials. Photic drive on high-frequency flash stimulation is another well-known interictal feature in migraineurs, associated with alpha-rhythm hyper-synchronisation. We compared therefore the influence of light stimulation on IDAP in healthy volunteers (HV) and migraine patients. A continuous flash stimulation was delivered during the recording of auditory evoked potentials at suprathreshold increasing stimulation intensities. IDAP was measured as the amplitude/stimulus intensity function (ASF) slope. In HV, the ASF slope decreased during flash stimulation, whereas, on average, there was no significant change in migraineurs. A closer analysis of migraineurs disclosed two subgroups of patients with no detectable clinical differences: one, the largest, in which the ASF slope was normal at baseline, but increased during light stimulation, the other with an increased ASF slope at rest and a decrease during light interference. Visual sensory overload is able to increase IDAP in the majority of migraineurs, which contrasts with HV. We hypothesise that this could be due to hyper-synchronisation of the alpha rhythm because of photic drive and possibly thalamo-cortical dysfunction. A minority of migraineurs have, like HV, an IDAP reduction during light interference. They are, however, characterised, unlike most HV, by a high IDAP at baseline. Besides underscoring the pathophysiological heterogeneity of migraine, these results suggest that light interference might improve the phenotyping of migraine patients who have a normal IDAP in the resting condition.

Migraine is associated with stimulus hypersensitivity, increased evoked cortical responses, and abnormal 5-HT levels in peripheral blood. We studied cortical auditory evoked potentials (AEPs) between attacks in 35 patients suffering from migraine without aura (MO, n = 25) or with aura (MA, n = 10) and in 25 healthy volunteers. Binaural tones were delivered at 40, 50, 60, and 70 dB sensation level (SL) in a pseudorandomized order. The intensity dependence of the auditory N1-P2 component was significantly greater in MO (p = 0.003) and MA (p = 0.02) patients than in healthy controls, resulting in a much steeper amplitude/stimulus intensity function slope. When three sequential blocks of 40 averaged responses were analyzed at the 40- and 70-dB SL intensities, N1-P2 amplitude decreased in second and third blocks at both intensities in controls, but increased in migraineurs, a difference that was significant in both blocks for the 70-dB SL stimulus. The strong interictal dependence of AEPs on stimulus intensity may thus be due to potentiation (instead of habituation) of the response during repetition of the high-intensity stimulation. In concordance with previous studies of visual evoked potentials, these results confirm that migraine is characterized between attacks by an abnormality of cortical information processing, which might be a consequence of low 5-HT transmission and favor cortical energy demands.

As shown in animal studies, 5HT1B/D agonists can inhibit activity in the trigeminal nucleus caudalis, which may be advantageous for their antimigraine effect. To demonstrate a possible central nervous system (CNS) action of these compounds in man we studied their effect on the intensity dependence of the cortical auditory evoked potentials (IDAPs), thought to be inversely related to central serotonergic transmission. An amplitude/stimulus intensity function (ASF) slope was computed in healthy volunteers and migraine patients between attacks before and 2 h after oral 311C90 (zolmitriptan "Zomig") 10 mg (n=14), 311C90 5 mg (n=7), sumatriptan 100 mg (n=14), dexfenfluramine 15 mg (n=4), lorazepam 1.25 mg (n=4) and placebo (n=14). 311C90 10 mg and, to a lesser degree, 5 mg significantly increased the mean ASF slope (p=0.007 and 0.05 vs placebo). There was a significant positive correlation between plasma levels of 311C90 and ASF slope changes. Sumatriptan and lorazepam had little effect, but dexfenfluramine produced a significant ASF slope decrease. 311C90 is able to modify a CNS activity that is modulated by serotonin, i.e. the IDAP. This effect is probably the consequence of its superior lipophilicity compared to sumatriptan and of activation of prejunctional 5HT1B/D autoreceptors, which lowers central serotonin release and thus the preactivation level of sensory cortices.
