There is a strong link between habitat loss, fragmentation of natural vegetation, and reduction of biodiversity in aquatic systems. The objective of this study was to evaluate the influence of different landscape scales on the community of Ephemeroptera, Plecoptera, and Trichoptera in Atlantic Forest rivers. We sought to understand how aquatic communities are affected by different habitat structures and anthropogenic changes in different spatial scales (in radii of 30, 50, 100, 150, and 200 m). Seven points were established where eight sample campaigns were carried out between 2015 and 2016. The analyses indicate the types of land use, with forest cover being of greatest expressiveness, as determinants in the structure and diversity of the Ephemeroptera, Plecoptera, and Trichoptera community. When evaluating the effect of the scales, for the basin evaluated, it was detected that the 30 and 50 m buffers were the most representative. These buffers suggest that the configuration and composition of landscape, especially the forest cover class, have a strong influence on the composition of the aquatic entomofauna in the region. The results confirm the importance of studies at local scales regarding the relation of the landscape for Ephemeroptera, Plecoptera, and Trichoptera biodiversity in view of the particular relationship of these orders with the riparian forest for its various functions. It is concluded that riparian forests in the 30 and 50 m scales should not be modified; otherwise, aquatic biodiversity will be compromised.Purpose To evaluate the development and rate of growth in macular atrophy after intravitreal injections of aflibercept (IVAs) for neovascular age-related macular degeneration (AMD) over a 2-year period. Study design Retrospective, interventional, consecutive case series. Methods This study included 94 eyes of 92 patients with treatment-naïve AMD involving the foveal center treated with IVAs at 3 university hospitals in Japan. The patients underwent IVAs bimonthly after 3 initial monthly doses in the first year. The protocol was converted to a treat-and-extend regimen in the second year. The incidence and growth rate of macular atrophy were quantified based on hypoautofluorescence detected by fundus autofluorescence images. Additionally, possible background factors related to the development and rate of growth of macular atrophy were investigated. Results Of 94 eyes, 39 (41.5%) had typical AMD and 55 (58.5%) had polypoidal choroidal vasculopathy. Ten eyes (10.6%) had macular atrophy at the baseline. Of the remaining 84 eyes, 14 (16.7%) had developed new macular atrophy at 2 years, the square root of the growth rate of atrophy was 0.52 mm/year. In multivariate analyses, a poorer best-corrected visual acuity (P = 0.01) and the presence of intraretinal fluid (P = 0.04) at baseline were found to be the independent predictors for the development of macular atrophy. No factors were found that were significantly related to the growth rate of the macular atrophy. Conclusions Our study determined the incidence and rate of growth of macular atrophy after IVAs for neovascular AMD in clinical settings. Eyes with vision reduction and intraretinal fluid at the baseline develop macular atrophy more frequently after IVAs for neovascular AMD.Purpose To evaluate clinical outcomes and enucleation rates after intravitreal melphalan (IVM) alone and after IVM combined with intravitreal topotecan (IVT) for the treatment of vitreous disease, and to a lesser extent subretinal and retrohyaloid seeds, in patients with retinoblastoma. Study design A retrospective analysis of 77 eyes of 72 consecutive patients. Methods Demographic data, classification of tumors, seed type (dust, sphere or cloud) before injection and at the end of follow-up, injection type (IVM or IVM+IVT), doses of IVM and IVT, number of injections, follow-up time, enucleation status and side effects were recorded. Cox regression analysis and log-rank test for Kaplan-Meier curves were performed. Triparanol chemical structure Results Of 77 eyes, 40 received IVM alone (group 1) and 37 received IVM+IVT (group 2). Enucleation rates were 62.5% (n=25) in group 1 and 10.8% (n=4) in group 2 (p=0.001). Median eye survival was 23.6 months in group 1 and 25.6 months in group 2. Mantel-Cox test revealed statistically significant differences between Kaplan-Meier curves of group 1 and 2 (p=0.022). Multiple Cox regression analysis showed a significantly elevated enucleation rate associated with IVM only treatment group (p=0.019) and pre-injection cloud type of seeding (p=0.014). Conclusion The combined use of intravitreal melphalan and topotecan provides significantly better results in terms of avoiding enucleation and vitreal and subretinal seed control.Methane (CH4) emission estimations for cattle in Sub-Saharan Africa (SSA) reflect limited production levels and diets that are high in cellulose forage. However, data on these livestock systems is lacking for their accurate evaluation. To provide guidance for climate change mitigation strategies in Senegal, it is necessary to obtain reliable estimates of CH4 emissions from Ndama cattle reared in grazing systems, which is the predominant cattle system in the country. The objective of this study was to determine the annual methane emission factor (MEF) for enteric fermentation of Ndama cattle following the IPCC Tier 2 procedure. Our estimated annual MEF at the herd scale was 30.8 kg CH4/TLU (30.7 kg CH4/head/yr for lactating cows and 15.1 kg CH4/head/yr for other cattle). These values are well below the default IPCC emission factor (46 and 31 kg CH4/head/yr for dairy and other cattle, respectively) proposed in the Tier 1 method for Africa. Our study showed that feed digestibility values differ with season (from 46 to 64%). We also showed that cattle lose weight and adapt to lower feed requirements during the long dry season, with a resulting major reduction in methane emissions. The results of this work provide a new framework to re-estimate the contribution of grazing systems to methane emissions in Africa.A study was conducted to analyze the effect of genetic and non-genetic factors influencing the growth performance of the West African Dwarf goat. Breed records of 836 kids born by 259 does, and 8 bucks from 2011 to 2017 at the station were used. Growth performance traits studied were birth weight, weaning weight, 6-month body weight, 9-month body weight, yearling weight, and pre-weaning and post-weaning growth rates. The fixed effects of sex of kid (male or female), season of kidding (major, minor, and dry), year of kidding (2011-2017), and type of birth (single, twins, or triplets) on growth performance were determined. Genetic parameters such as heritability and correlations among the traits were also estimated. The non-genetic data (fixed factors) obtained were analyzed using the general linear model procedures of GenStat (Discovery Edition 12). Heritability estimates obtained for the growth traits were 0.45 ± 0.15, 0.57 ± 0.29, 0.04 ± 0.05, 0.74 ± 0.59, 0.49 ± 0.35, 0.55 ± 0.39, and 0.54 ± 0.36, respectively, an indication of high genetic variation existing among the traits (with the exception of 6-month body weight).
