Investigating Antimicrobial Resistance in Salmonella Meningitis: A Nigerien Perspective
Pages: 8–13
Abstract
Citation
Salmonella meningitis prognosis is poor and the choice of adequate antibiotic therapy is difficult in developing countries where laboratory testing is not accessible. This study aimed to evaluate, the antibiotic susceptibility pattern of salmonella isolated from CSF in meningitis suspected cases and to identify the best drug option. From 2011 to 2015, 6630 CSF collected were sent at CERMES, during laboratory-based surveillance. All turbid and freshly collected CSF from under 5 years patients were subjected to standard bacteriological method for isolation and characterization of meningitis etiologies. A total of 11/6630 Salmonella strains were isolated during this study. This accounted for 0. 2% of the overall CSF analyzed during the 5 years of study. Most of the patients (72.7%) were less than 2 years old. The average age of children was 2.63 years with an extreme of 1 month to 14 years and the sex ratio M/F was 0.83. The antimicrobial susceptibility was performed in vitro, to all the 11 salmonella isolated. The result revealed that 9/11(81.8%) strains were susceptible to ceftriaxone, Amikacin, and Cefoxitin. All the isolates (100%) were sensitive to Imipenem, Nalidixic acid, and Ciprofloxacin. Two strains of salmonella (18.2%) belonged to extended-spectrum beta lactamase (ESBL) producing group.The maximum resistance was observed against Ampicillin (100%), Amoxicillin/clavulanic acid (72.7%) and Gentamicin (27.3%).The Ampicillin MIC value showed 100% resistance to all the strains tested. This study confirmed that ceftriaxone may be used to treat Salmonella meningitis.The isolation of ESBL salmonella strain may be an alarm indicating the worldwide spray of multi-resistant bacterium. However, the limitation in the use of cephalosporin may prevent this increasing resistance.

Dynamics of Nonlocal Rods via Fractional Laplacian Analysis
Pages: 14–30
Abstract
Citation
: The use of fractional models to analyse nonlocal behaviour of solids has acquired great importance in recent years. The aim of this paper is to propose a model that uses the fractional Laplacian in order to obtain the equation ruling the dynamics of nonlocal rods. The solution is found by means of numerical techniques with a discretisation in the space domain. At first, the proposed model is compared to a model that uses Eringen’s classical approach to derive the differential equation ruling the problem, showing how the parameters used in the proposed fractional model can be estimated. Moreover, the physical meaning of the model parameters is assessed. The model is then extended in dynamics by means of a discretisation in the time domain using Newmark’s method, and the responses to different dynamic conditions, such as an external load varying with time and free vibrations due to an initial deformation, are estimated, showing the difference of behaviour between the local response and the nonlocal response. The obtained results show that the proposed model can be used efficiently to estimate the response of the nonlocal rod both to static and dynamic loads.

Optimization Strategies for Sectorized Cellular Networks with Heterogeneous Latency Requirements
Pages: 42–47
Abstract
Citation
—The sectorized hexagonal model with mixed delay constraints is considered when both neighbouring mobile users and base stations can cooperate over rate-limited links. Each message is a combination of independent “fast” and “slow” bits, where the former are subject to a stringent delay constraint and cannot profit from cooperation. Inner and outer bounds on the multiplexing gain region are derived. The obtained results show that for small cooperation prelogs or moderate “fast” multiplexing gains, the overall performance (sum multiplexing gain) is hardly decreased by the stringent delay constraints on the “fast” bits. For large cooperation prelogs and large “fast” multiplexing gains, increasing the “fast” multiplexing gain by ∆ comes at the expense of decreasing the sum multiplexing gain by 3∆.

Buckling Analysis of Periodic Micro-structured Beams: A Timoshenko-based Homogenization Approach.
Pages: 48–64
Abstract
Citation
: In this paper, a Timoshenko beam model is formulated for buckling analysis of periodic micro-structured beams, uniformly compressed. These are planar grid beams, whose micro-structure consists of a square lattice of equal fibers, modeled as Timoshenko micro-beams. The equivalent beam model is derived in the framework of a direct one-dimensional approach and its constitutive law, including the effect of prestress of the longitudinal fibers, is deduced through a homogenization approach. Accordingly, micro–macro constitutive relations are obtained through an energy equivalence between a cell of the periodic model and a segment of the equivalent beam. The model also accounts for warping of the micro-structure, via the

The Impact of Concomitant Exposure to Arsenic, Cadmium, and Lead on Reproductive Health and Oxidative Stress in Female Rats
Pages: 65–73
Abstract
Citation
Background : Toxicological consequences arising from exposure to mixtures of heavy metals especially at low, chronic and environmentally relevant doses are poorly recognised. In the present study, we evaluated effects of chronic exposure to combinations of three metals arsenic (As), cadmium (Cd) and lead (Pb) present frequently in drinking water on reproductive function and oxidative damage caused to reproductive organs of female rats. Method : Female rats were exposed to mixture of metals (As, Cd& Pb) for 90 consecutive days. The gain in body weight and weight of reproductive organs were recorded following autopsy on 91 stday. The oestrus cycle were monitored during entire treatment period. Numbers of corpora lutea, implantation sites, live fetus and survival of the fetus were evaluated in rats mated successfully with untreated male after completion of their respective treatment. Ovarian cholesterol, protein, ascorbic acid and enzyme Δ5-3β HSD levels were estimated. Serum levels of steroid hormones oestrogen and progesterone were estimated. Histopathological picture of both ovary and uterus were assessed. Levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidise (GPX) activity, amount of reduced glutathione (GSH) and malondyaldehyde (MDA) in blood, ovary and uterus were measured as biomarkers of oxidative stress. Results : The treated rats showed reduced body weight gain and reduction in the weight of ovary and uterus. Oestrus cycle was disrupted with continuous diestrous in treated animals. Number of corpora lutea, implantation sites and live fetus and the survival of fetus evaluate were reduced significantly in treated groups. The levels of ovarian cholesterol and ascorbic acid increased in treated rats with decrease Δ5-3β HSD level. There was reduction in serum level of both the ovarian steroid hormones oestrogen and progesterone. The protein levels did not differ between the groups. There was a significant increase in levels of MDA and decrease in levels of all the antioxidant enzymes in treated group. Conclusion : The results revealed there was disruption to reproductive functions with decrease in stereoidogenic activity and associated oxidative stress in female rats treated with combination of mixture of metals (Cd, As and Pb) at low dose for 90 consecutive days.
