    This is the protocol for a review and there is no abstract. The objectives are as follows: To estimate the benefit and safety of all DMDs that have been evaluated in all studies (randomised and non-randomised) for early treatment. We will employ novel, high-quality methods for systematic reviews and network meta-analysis in collaboration with the Cochrane Multiple Interventions Group. To evaluate the quality of the evidence provided by existing studies. We will consider the credibility of included studies and other characteristics of the evidence base as we characterise conclusions pertaining to high, low or very low quality of evidence. We will undertake this review in accordance with the methods described by the template protocol published online and will use this template as we prepare the review

    Dietary intake of xylose impacts the transcriptome and proteome of tissues involved in xylose metabolism in swine

    Xylose is a primary component of arabinoxylan in swine diets. As arabinoxylan is a significant component of fiber, and fiber is generally rising in practical pig diets globally, the study of arabinoxylan and xylose is of increasing interest. However, the mechanisms by which free xylose may be absorbed and the pathways impacted by xylose have yet to be elucidated in pigs. The objective of this study was to determine the impact of xylose supplementation on gene expression and protein abundance in jejunum, kidney, liver, and muscle tissues which have previously been identified as possible sites of xylose absorption or metabolism. This study aimed to expand the preliminary understanding of dietary xylose metabolism and utilization in pigs. One study, replicated twice with 24 crossbred gilts, was used to assess two dietary treatments: a xylose-free (0%) control and 8% D-xylose. The impact of xylose on growth was monitored by measuring initial and final body weight, serum IGF-1, and liver glycogen concentrations. The rate and efficiency of weight gain were reduced on the xylose diet but not to a level that would occur if xylose was not used at all; the detection of xylose systemically further supports this conclusion. This study confirmed that pigs can utilize dietary xylose. To determine the impact of xylose on tissue metabolism, samples were collected from all four tissues for gene expression analysis by RNA-sequencing, and kidney and liver samples were subjected to proteomic analysis using 2D-DIGE and mass spectrometry. The majority of differentially expressed (DE) genes were identified in the kidney samples (n = 157), with a few identified in the jejunum (n = 16), liver (n = 1), and muscle (n = 20) samples. The DE genes in the kidney were mainly identified as being involved in lipid biosynthesis and fatty acid metabolism. Proteomic results corroborated these findings. Although the inclusion of xylose in a diet at practical levels is shown to impact energy metabolic processes, it has been confirmed that this five-carbon sugar can support levels of growth only slightly below those of glucose, a six-carbon sugar that is more commonly utilized as an energy source in pig diets

    Kiwifruit (Actinidia deliciosa) is one of the significant commercial crop in Iran. A destructive Kiwifruit (Actinidia deliciosa) is one of the most significant commercial crops in Iran. In 2015 a destructive disease of kiwifruits was observed in orchards, storage facilities and retail markets, resulting in great economic loss to producers. In this study phenotypic and molecular techniques were applied to characterize the causal agent of kiwifruit rot observed in Mazandaran province, northern Iran. From the similarity among the results of pathogenicity tests, equivalency with standard taxonomic criteria for disease and PCR-based analysis of the ITS region, all the isolates were identified as Botryosphaeria dothidea

    A robust fuzzy optimisation for a multi-objective pharmaceutical supply chain network design problem considering reliability and delivery time

    © 2020 Informa UK Limited, trading as Taylor & Francis Group. Due to the emergency role of pharmaceutical supply chains, there has been rapid development of optimisation techniques as one of efficient tools to improve pharmaceutical supply chain network design. To improve the pharmaceutical supply chain network, this study proposes a novel location-allocation-inventory model as a multi-objective, multi-echelon, multi-product, multi-period and multi-modal transportation system for pharmaceutical supply chain network design under uncertainty. The proposed model aims to optimise multiple objectives, including minimising the total costs and the delivery time while maximising the transportation system reliability simultaneously. To control the impacts of uncertain parameters including the ordering, delivery, purchase, and transportation costs and the capacity of vehicles, warehouses and of distribution centres, a robust fuzzy optimisation approach is developed. An efficient modification of a state-of-the-art evolutionary algorithm called the red deer algorithm (RDA) in its multi-objective form abbreviated as IMORDA is developed and compared with itself and well-established algorithms in the literature such as non-dominated sorting genetic algorithm (NSGA-II) and multi-objective particle swarm optimisation (MOPSO). The results confirm the applicability and efficiency of the IMORDA for the proposed model and encourage further development of this new metaheuristic
