Background： This article traces the history of scientific ideas connecting forest cover with rainfall to inform ongoing debates about whether forests are net users or producers of water in the hydrological cycle. Scholars of the supply-side school argue that forests are net producers and magnifiers that increase rainfall at regional scales. Supply-side scholars seek to challenge the dominance of demand-side thinking. The demand-side school emphasizes that trees are net users of water within a catchment that decrease overall water available for other users. This scientific debate has significant implications for the development of policies to manage forests and water. Results： Scientists have debated the question of whether forests improve or worsen water balance for over two hundred years. Connections between forests and rainfall gained prominence in scientific circles during the second half of the nineteenth century and again during the past three decades. The popularity of forest- rainfall connections has paralleled societal and scientific interest in anthropogenic climate change and deforestation. Theories connecting forests with rainfall peaked in popularity in the 1850s to 1880s, a period when scientists expressed alarm that deforestation caused regional declines in precipitation. Forests were understood to create rain within a locality and region. Scientific consensus shifted by the early twentieth century to the view that forests did not play a significant role in determining rainfall. The forest-rainfall connection reemerged in the 1980s alongside advances in climate modelling and growing fears of anthropogenic global warming and tropical deforestation. Using new data and theories, supply-side advocates have once again placed a strong forest-rainfall connection into scientific prominence. Conclusion： Supply-side management policies have a checkered history that should elicit caution, while demand-side policies, which are based on almost a century of hydrolog

AIm: To describe the disease and psychosocial outcomes of an inflammatory bowel disease (IBD) transition cohort and their ***: Patients with IBD, aged > 18 years, who had moved from paediatric to adult care within 10 years were identified through IBD databases at three tertiary hospitals. Participants were surveyed regarding demographic and disease specific data and their perspectives on the transition process. Survey response data were compared to contemporaneously recorded information in paediatric service case notes. Data were compared to a similar age cohort who had never received paediatric IBD care and therefore who had not undergone a transition ***: There were 81 returned surveys from 46 transition and 35 non-transition patients. No statistically significant differences were found in disease burden, disease outcomes or adult roles and responsibilities between cohorts. Despite a high prevalence of mood disturbance (35%), there was a very low usage (5%) of psychological services in both cohorts. In the transition cohort, knowledge of their transition plan was reported by only 25/46 patients and the majority (54%) felt they were not strongly prepared. A high rate (78%) of discussion about work/study plans was recorded prior to transition, but a near complete absence of discussion regarding sex (8%), and other adult issues was recorded. Both cohorts agreed that their preferred method of future transition practices (of the options offered) was a shared clinic appointment with all key ***: Transition did not appear to adversely affect disease or psychosocial outcomes. Current transition care processes could be optimised, with better psychosocial preparation and agreed transition plans.

BACKgROUND： Rifampicin inhibits the formation of a-synuclein multimer and protects against 1-methyl-4-phenyl-1,2, 3, 6-tetrahydropyritine （mPTP）-induced PC12 cell apoptosis. OBJECTIVE： To compare the effect of rifampicin pre- and post-treatment on tyrosine hydroxylase and α-synuclein expression in substantia nigra pars compacta in a rat model of Parkinson＇s disease. DESIgN, TImE AND SE＇B＇INg： A randomized, controlled experiment was performed at the Experimental Animal Center of Sun Yat-sen University North Campus （China） from November 2006 to October 2008. mATERIALS： Rifampicin was purchased from mD, USA; rotenone was purchased from Sigma, USA; mouse anti-rat α-synuclein monoclonal antibody was purchased from B＆D, USA; and rabbit anti-rat tyrosine hydroxylase monoclonal antibody was purchased from Chemicon, USA. mETHODS： A total of 72 male, Sprague Dawley rats, aged 8 weeks, were randomly assigned to 5 groups： blank control （n = 12）, rifampicin （n = 12）, rotenone （n = 16）, rifampicin pre-treatment （n = 16）, and rifampicin post-treatment （n = 16）. Parkinson＇s disease model rats were established via a subcutaneous injection of rotenone （1.5 mg/kg per day） in the three treatment groups, once a day for 3 successive weeks. Rifampicin （30 mg/kg per day） was intragastrically administered in the rifampicin pre-treatment group 3 days prior to rotenone induction and in the rifampicin post-treatment group 7 days after rotenone induction. Rats were treated with a subcutaneous injection of 1 mL/kg per day sunflower oil in the blank control group and an intragastric injection of 30 mg/kg per day rifampicin in the rifampicin group, once a day for 3 successive weeks in total. mAIN OUTCOmE mEASURES： Prior to treatment and in the end of the 3^rd week after treatment, the rats were evaluated using the modified neurological severity score. The substantia nigra from the rats was extracted for hematoxylin-eosin staining. western blot analysis was performed to determine tyrosine hydroxyla

Intra- and interspecific variation in plant and insect traits can alter the strength and direction of insect-plant interactions, with outcomes modified by soil biotic and abiotic conditions. we used the potato aphid （macrosiphum euphorbiae Thomas） feeding on cultivated Solanum tuberosum and wild Solanurn berthaulti to study the impact of water availability and plant mutualistic arbuscular mycorrhizal （Am） fungi on aphid performance and susceptibility to a parasitoid wasp （Aphidius ervi Haliday）. Plants were grown under glass with live or sterile Am fungal spores and supplied with sufficient or reduced water supply. Plants were infested with 1 of 3 genotypes ofm. euphorbiae or maintained as aphidfree controls; aphid abundance was scored after 1 week, after which aphid susceptibility to A. ervi was assayed explanta. Solarium tuberosum accumulated c. 20% more dry mass than S. berthaultii, and root mass of S. berthaultii was smallest under reduced water supply in the presence of Am fungi. Aphid abundance was lowest on S. berthaultii and highest for genotype ＂2＂ aphids; genotype ＂1＂ aphid density was particularly reduced on S. berthaultii. Aphid genotype ＂1＂ exhibited low susceptibility to parasitism and was attacked less frequently than the other two more susceptible aphid genotypes. Neither Am fungi nor water availability affected insect performance. Our study suggests a fitness trade-offin m. euphorbiae between parasitism resistance and aphid performance on poor quality Solarium hosts that warrants further exploration, and indicates the importance of accounting for genotype identity in determining the outcome of multitrophic interactions.
