Abstract: In this study, the effect of a dietary supplementation of Tilia tomentosa on growth performance and digestive enzyme activities in juvenile common carp (Cyprinus carpio) were evaluated. C. carpio, with an average weight of 4.35 ± 0.16 g, were fed diet with supplemented with a celery (Tilia tomentosa) aqueous methanolic extract at the dose of 0 mg kg-1 (control), 100 mg kg-1 , 500 mg kg-1 and 1000 mg kg-1 during 45 days. At the end of the study, the final weight was significantly increased in the 100 mg kg-1 , and 1 mg kg-1 compared with the control group (P < 0.05). The weight gain rate was also significantly increased in the experimental groups’ compared with the control (P < 0.05). The feed conversion ratio was significantly decreased in the 500 mg kg-1 and 1000 mg kg-1 groups compared with the control (P < 0.05). The specific growth rate was significantly increased in the 500 mg kg-1 and 1000 mg kg-1 groups compared with control group (P < 0.05). The digestive enzymes activity (Amylase, lipase and trypsin) was also measured and no significant differences in the enzymes activities were determined at the end of the study compared to control (P > 0.05). 

Software Defined Networking (SDN) is an important paradigm shift of computer networking in the last 10 years. The concept of SDN is so powerful that the potential of applying it can easily be perceived beyond the initial use case of large data centre networks. We are motivated by this perception to explore the potential use of SDN in the context of home networks specifically, even though home environments were not the driving scenario behind SDN in the first years of its development. Lacking other reviews on the subject, we performed a focused search for every article that proposes, discusses or otherwise addresses the idea of implementing SDN in home networking. We surveyed four major technical and online databases (IEEE Xplore, ACM, ScienceDirect and Wiley) to ensure the inclusion of relevant, quality and authentic works. The final filtered set included 42 articles that spanned the period from 2010 to 2017. Most of the articles address specific aspects of controlling and managing home networks, such as Quality of Experience, security, Internet caps, Internet-of-Things device management and other specific themes, while the rest of articles address the generic case of managing home networks using SDN without a special focus on a particular target application. We derive a simple taxonomy for the works on home SDN and summarize the complete set of works, highlighting few points along the way and drawing few simple statistics.

Swallowwort (Cynanchum acutum L., family Asclepiadaceae) is a perennial invasive species of profound medicinal potentiality. The spread of C. acutum in diverse habitats differing in water status and extent of salinity might point to appreciable resistance of the plant to drought and salt stress. The response of C. acutum to water stress under controlled nutrient supply on sand culture was investigated to assess the effect of water status of the soil on plant use efficiency of water and nutrients. Plants were subjected to water regime (% field capacity) of: 100, 35, 25, 12.5 and 5 for 10 days in a greenhouse. Whereas plant fresh weight was reduced under the impact of water stress, dry weight exhibited its maximum under moderate drought and this was associated with the allocation of greater proportions of plant biomass to root and stem at the expense of leaves. The increase in photosynthetic pigments of stressed plants is related to the drought-induced P deprivation. The rates of photosynthesis and transpiration and the stomatal conductance were progressively inhibited under drought stress; but sub-stomatal CO 2 concentration showed a minimum at 12.5% field capacity. Soluble sugars and starch were deprived whereas proline was accumulated in the leaves under drought stress. Drought stress affected the uptake and partitioning of minerals within the plant and increased use efficiency of water and minerals, particularly P

In this article, an implementation of an efficient numerical method for solving the system of coupled non-linear fractional (Caputo sense) dynamical model of marriage (FDMM) is introduced. The proposed system describes the dynamics of love affair between couples. The method is based on the spectral collocation method using Legendre polynomials. The proposed method reduces FDMM to a system of algebraic equations, which solved using Newton iteration method. Special attention is given to study the convergence analysis and deduce an error upper bound of the resulting approximate solution. Numerical simulation is given to show the validity and the accuracy of the proposed method. 

In this paper we establish the existence of integrable solution of boundary value problems of (mixed type) Fredholm - volterra functional integro-differential equations  with nonlocal boundary conditions.

Mathematical modelling of real-life problems usually results in functional equations, like ordinary or partial differential equations, integral and integro- differential equations, stochastic equations. Many mathematical formulation of physical phenomena contain integro-differential equations, these equations arises in many fields like fluid dynamics, biological models and chemical kinetics integro-differential equations are usually difficult to solve analytically so it is required to obtain an efficient approximate solution.

In this paper we establish the existence of solution for two boundary value problems of Fredholm functional integro-differential equations with nonlocal boundary conditions.

Abstract. Cytochrome P450s (P450s) involved in insecticide resistance reduce the effi cacy of insecticide-based vector control by rendering vector control ineffective. They are recorded in many species of vectors and have various constitutive and insecticide induction profi les. In this study, the isolation and prediction of the structure of a P450 from a strain of Aedes aegypti originating from Malaysia is reported. Quantitative mRNA expression of this gene and a previously reported P450, CYP4H28v2, in the devel opmental stages of the mosquito after exposure to sub-lethal concentrations of insecticides is also reported. The isolated P450, CYP4H31v2, is an allelic variant of CYP4H31 and contains several conserved motifs of P450s. The secondary structure of the protein is mostly made up of alpha helices and random coils. The tertiary structure was generated using homology modeling and was of good quality based on structure validation using protein structure assessment tools. CYP4H28v2 and CYP4H31v2 were differentially expressed in the developmental stages of the vector, with a signifi cantly increased expression in adult males. The genes were signifi cantly over-expressed in larvae exposed to deltamethrin and permethrin for 6 h. In the DDT-treated larvae, only CYP4H31v2 was signifi cantly over-expressed after a 6 h exposure. Under-expression of the genes was predominant in larvae treated with the organophosphates malathion and temephos. Though the functions of these P450s are unknown, their response to induction by exposure to insecticides indicates the likely involvement of these genes in insecticide tolerance.

Objective

To clone cytochrome P450 from Aedes aegypti (Ae. aegypti) and determine the characteristics using bioinformatics tools.

Methods

Cytochrome P450 of Ae. aegypti was amplified using polymerase chain reaction, cloned and sequenced. Evolutionary relationship of the sequence was inferred and bioinformatics tools were used to predict subcellular localisation, signal peptide, transmembrane helix, phosphorylation, O-glycosylation, secondary and tertiary structures of the deduced protein.

Results

Polymerase chain reaction rather amplified a cytochrome P450 pseudogene which was named CYP4H44P (GenBank accession number KF779932). The pseudogene has 1 537 nucleotides and an open reading frame of 335 amino acids containing cytochrome P450 motifs except the WxxxR motif. It is highly homologous to CYP4H28 and CYP4H28v2.
