Implication of Proteus spp in the Pathology of Nosocomial Wound Infection in Northeastern Nigeria

Aims: To determine the infection rate and antibiogram of Proteus spp among hospitalised patients suffering from wound infection in Maiduguri. Methodology: A total of 320 wound swab samples were collected from August 2016 to June 2017, and processed via microscopy, culture and further confirmed by biochemical tests. Kirby bauer disc diffusion test was used to determine the antimicrobial susceptibility pattern of Proteus spp isolated. Results: Twenty eight (28) samples yielded Proteus spp, giving a prevalence rate of 8.75%. Male patients were more affected (60.71%) compared to females (39.29%). Difference in sex in relation to rate of infection was statistically not significant (X2 =3.963, p<.01). Patients within the age group of 21-30 years (28.57%) recorded the highest bacterial yield while those of 61-70 years and >70 years (3.57% respectively) recorded the least. Patients suffering from Wound Sepsis and Burns recorded the most significant infection rate (28.57% respectively). Proteus mirabilis (53.57%) was the most isolated Proteus specie while Proteus penneri (7.14%) was the least. Proteus spp isolates demonstrated a marked resistance against Augmentin (89.29%) and Nalidixic Acid (85.71%) but high sensitivity was observed towards Ciprofloxacin (85.71%) and Streptomycin (78.57%). Conclusion: We establish that Proteus spp actually contribute to the pathology of wounds infection among hospitalised patients, and the Proteus specie most implicated in the aetiology of wound infection is Proteus mirabilis. Ciprofloxacin and Streptomycin are the drugs of choice for the treatment of patients with Proteus spp wound infection in the study area, and the use of Nalidixic acid and Augmentin is highly discouraged due to high resistance.

Analysis, Design, Modeling, and Control of an Interleaved-Boost Full-Bridge Three-Port Converter for Hybrid Renewable Energy Systems

This paper presents the design, modeling, and control of an isolated dc-dc three-port converter (TPC) based on an interleaved-boost full-bridge converter with pulsewidth modulation (PWM) and phase-shift control for hybrid renewable energy systems. In the proposed topology, the switches are driven by phase-shifted PWM signals, where both phase angle and duty cycle are the controlled variables. The power flow between the two inputs is controlled through the duty cycle, whereas the output voltage can be regulated effectively through the phase shift. The primary-side MOSFETs can achieve zero-voltage-switching (ZVS) operation without additional circuitry. Additionally, due to the ac output inductor, the secondary-side diodes can operate under zero-current-switching (ZCS) conditions. In this study, the operation principles of the converter are analyzed and the critical design considerations are discussed. The dynamic behavior of the proposed ac-inductor-based TPC is investigated by performing state-space modeling. Moreover, the derived mathematical models are validated by simulation and measurements. In order to verify the validity of the theoretical analysis, design, and power decoupling control scheme, a prototype is constructed and tested under the various modes, depending on the availability of the renewable energy source and the load consumption. The experimental results show that the two decoupled control variables achieve effective regulation of the power flow among the three ports.

Az Észlelt Irodai Magánszféra Kérdőív adaptálása magyar nyelvre

a question naire to measure employee-office environment transaction in offices. Methods: We adapted Oldham’s (1988) Experience of privacy questionnaire 2 to Hungarian as “Észlelt Irodai Magánszféra Kérd ő ív”, and we attempted to develop a modified version of the tool at a Development Center. Besides examining internal consistency, exploratory and confirmatory factor analyses were performed. In order to test the validity of the questionnaire, we compared the scale’s values with the architectural privacy of and the general level of satisfaction with the work. Results: Results showed acceptable internal consistency and based on the factor analysis, we adopted the one-factor structure proposed by Laurence et al. (2013). We found a significant positive relationship between the level of experience of privacy and general satisfaction with the work environment, and those working in enclosed office space reported higher level of experienced privacy – as expected. We did not justify the validity of the modified version of the questionnaire. Discussion: The questionnaire can be used in the Hungarian context, so we hope it can contribute to the assessment of work environments in domestic organizations.

Mechanisms of genotoxicity of inhalable particles: in vitro & in vivo investigations

The aim of this thesis was to elucidate the mechanisms leading to oxidative DNA damage after particle exposure. In this regard one has to distinguish between primary (particle-driven) and secondary (inflammation-driven) genotoxicity. Three independent studies were performed, which were different in the choice of particulate matter and experimental set-up. In study 1 the human lung epithelial cell line A549 was exposed to size-fractionated ambient PM samples, collected from locations with contrasting traffic profiles. Significant differences were found in oxidant-generating capacity, cytotoxicity, interleukin-8 release and oxidative DNA damage. Effects were found to depend more on the sampling site than on the size fraction. The data confirm that traffic is an important factor for the toxic potential of ambient PM samples. In addition, significant correlations were observed between the oxidant generating potential and all toxicological endpoints. Study 2 revealed, that short-time inhalation of carbonaceous nanoparticles (150 µg/cm³) leads neither to pulmonary inflammation nor to an induction of oxidative DNA damage and associated induction of DNA repair genes in whole lung tissue of mouse or alveolar epithelial cells isolated from rats. Study 3 was performed to reveal the role of reactive oxygen species (ROS) from the phagocyte NADPH-oxidase during particle-elicited inflammation. Although an influx of inflammatory cells into the lung of wildtype as well as p47phox-/- mice was observed after pharyngeal aspiration of quartz particles, oxidative stress appeared only in wildtype mice. No effects were found regarding oxidative DNA damage and expression of DNA repair genes. In contrast, the importance of NADPH oxidase-mediated ROS formation in quartz induced genotoxicity was shown in a coculture model of bone-marrow derived neutrophils and A549 cells. The results of this thesis showed, that pulmonary inflammation is of major importance for the induction of oxidative DNA damage after particle exposure. NADPH-oxidase generated ROS by neutrophilic granulocytes seems to contribute to genotoxic effects after particle exposure. In addition to the pulmonary inflammation the chemical composition (transition metals, PAH, particle surface properties) of ambient particles seems to play an important role.
Diversidade molecular e funcional de proteínas da saliva de Triatoma infestans, um vetor da doença de Chagas

Salivary anti-hemostatic activities are widely distributed in hematophagous arthropods including Triatoma infestans (Hemiptera, family Reduviidae, subfamily Triatominae), a vector of Chagas’ disease. The saliva of T. infestans mediates hydrolysis of NDBC6HPC, a substrate for Platelet-activating factor-acetylhydrolase (PAF-AH), at neutral pH. Purification of the protein responsible for this activity was achieved by a twostep FPLC procedure using cation exchange and hydrophobic columns. Optimal enzyme activity was found to be Ca-independent and was associated with a single 17-kDa protein (PAF-AH of T. infestans; PATi) on SDS-PAGE under reducing conditions. Mass spectrometry experiments suggest that PATi is a member of the phospholipase A2 family. Specific antibodies localized the enzyme in the luminal content of the salivary glands D2. These findings suggest that hydrolysis of PAF may facilitate the insect to avoid host hemostatic and/or nociceptive responses.
The Gene Tbx5 Links Development, Evolution and Adaptation of the Sternum in Terrestrial Vertebrates

The transition from fins to limbs during the colonisation of land was a key innovation in vertebrate evolution. Changes in the limb and shoulder girdle during this event have been investigated extensively, but little attention has been given to the acquisition of the sternum, a feature considered characteristic of virtually all terrestrial vertebrates, and which is mandatory for tetrapod locomotion. The sternum is a thin flat bone lying at the ventral midline of the thorax that provides a crucial attachment site for the pectoral muscles, allowing the forelimbs to raise the body up from the ground. I demonstrate that a sternum completely fails to form in conditional Tbx5 mutant mouse embryos. Consistent with this, sternum defects are a characteristic feature of Holt-Oram syndrome, which is caused by mutations in TBX5. While the role of Tbx5 in the development of the heart and forelimbs has been studied extensively, Tbx5 function in sternum formation is not understood. Using chick and mouse models systems, I set out to investigate the developmental origin of the sternum, and why it fails to form in the absence of Tbx5. Since the function of the sternum is to facilitate forelimb movement, I explored the correlation between forelimb use and sternum morphology by comparing sternum size across different avian species. I then investigated the genetic adaptations that could explain sternum and forelimb reduction in flightless birds, using the emu as a model. I suggest that Tbx5 represents a common node in the molecular pathways regulating forelimb and sternum development.
Alter-identity work via Social Media in Professional Service Contexts

In this research-in-progress paper, I show how individuals in a professional service firm passionately, and of their own volition, engage in work activities across multiple social media, that fall well outside of formal work requirements. I refer to the personas these workers create as “alter-identities” to signify that this form of identity work sits alongside formal work roles. Utilising a reflexive research approach, I set out to explore 1) how professionals maintain alter-identities and 2) implications vis-à-vis organisational expectations. I offer initial insights into the role of social media, and the ways in which individuals reconcile alter-identities with formal requirements. I will contribute new insights on the role of digital technologies, such as social media, in knowledge work contexts, and theorise the role of alteridentity performance as a way for organisations to innovate formal work models in a bottom-up, employee-driven way. Such practices might foster organisational responsiveness in rapidly changing environments.
Perceptions of Different Generations Regarding Managerial Competencies in Restaurants

Managerial competencies of restaurant managers play a major role in motivating employees to be productive and to provide excellent service which, in turn, will lead to customer satisfaction. Drawing upon generational differences in work ethics and values, the authors examine the importance of managerial competencies in three age cohorts. A quantitative research design was selected using a structured questionnaire consisting of five competency domains. Data were collected from 180 restaurant managers and employees in restaurants in the City of Tshwane. The results of the Fisher exact test indicated that the importance of managerial competencies differed significantly in the three age groups. Significant differences existed for three leadership domains, two management domains, one interpersonal and one intrapersonal domain. No significant differences were recorded for the perceptions of the different age groups regarding the importance of the technical domain. For the younger generation, the ability to grant employees the opportunity to grow was regarded as highly important by all respondents. The ability to maintain discipline in the workforce was perceived as less important by the youngest age group when it was compared to the other age groups. The youngest employees felt that the ability to be innovative was not as important unlike the perception of the older age groups. The findings of this study could lead restaurant managers to a better understanding of the different generational groups, how to motivate them thereby ensuring job satisfaction and service quality.
Head blight (Fusarium graminearum) and deoxynivalenol concentration in winter wheat as affected by pre-crop, soil tillage and nitrogen fertilization.

Fusarium head blight (FHB), caused by F. graminearum, is increasing world-wide. Fusarium mycotoxins are a serious threat of health and a reliable control by fungicides is not possible, yet. The present study was conducted in order to evaluate the influence of different pre-crops and crop husbandry on FHB incidence in winter wheat test crops. In a 2-years factorial field experiment on the experimental station Ihinger Hof of the University of Hohenheim (480 m a. S. 1., loam soil, 7,9 °C, 690 mm), inoculated pre-crops of maize or spring wheat were harvested for silage with only the stubble remaining in the field or for grain by combine with the whole straw remaining. Subsequently, crop residues were left on the soil surface or ploughed under before sowing winter wheat. Nitrogen fertilizer was applied to these test crops with calcium ammonium nitrate (CAN) or nitrolime. FHB was assessed by plot scores, by observations of disease incidence, disease severity and grain infection, indirectly via grain germination and by chemical deoxynivalenol (DON) analyses. The infection by FHB and the grain contamination with DON were similar after maize and spring wheat, either for silage or for grain, but the method of pre-crop inoculation by infected oat grains might have masked differences between pre-crops. The reductions of FHB incidence due to ploughing or nitrolime application were 27-32 % or 31-59 % compared with residues remaining on the surface or CAN fertilization, respectively. Contemporary reductions in DON were less consistent. The assessment of percent infected ears can be recommended as a comparatively fast method for FHB evaluation that showed significant correlations with DON concentration and grain germination, too. But a reliable estimation of DON concentrations is not possible on the basis of infection assessments. In conclusion, crop health can be supported by crop husbandry to some degree, but FHB cannot be reliably controlled in susceptible rotations with abundant sources of inoculum.
Potential feedbacks of northern wetlands on climate change: An outline of an approach to predict climate-change impact

Atmospheric concentrations of many greenhouse gases, in particular carbon dioxide and methane, are rapidly increasing from preindustrial levels. This paper explores the potential feedback from northern wetlands, particularly with regard to carbon dioxide and methane flux, to climate change. Although progress has been made in determining current trace gas fluxes from major biomass, the authors believe that a mechanistic approach is necessary to predict the direct and indirect feedbacks between climate and northern wetlands. Relevant areas covered in the article include the following: feedback mechanisms; carbon and nutrient mineralization; the kinetics of carbon and nutrient mineralization; methane oxidation and the role of plants; field dynamics of gases in a meadow and bog in Minnesota; and extrapolating to larger scales. 80 refs., 8 figs., 1 tab.
Universality of Random Matrices With Dependent Entries

This dissertation deals with two random matrix models with dependent entries. The first model is a random matrix with generic slow-varying correlation. The second model is the addition of two Hermitian matrices, conjugated by generic random unitary matrices. For both models, local laws for empirical spectral measures and universality of local spectral statistics are proved.
Climate‐mediated changes in marine ecosystem regulation during El Niño

The degree to which ecosystems are regulated through bottom‐up, top‐down, or direct physical processes represents a long‐standing issue in ecology, with important consequences for resource management and conservation. In marine ecosystems, the role of bottom‐up and top‐down forcing has been shown to vary over spatio‐temporal scales, often linked to highly variable and heterogeneously distributed environmental conditions. Ecosystem dynamics in the Northeast Pacific have been suggested to be predominately bottom‐up regulated. However, it remains unknown to what extent top‐down regulation occurs, or whether the relative importance of bottom‐up and top‐down forcing may shift in response to climate change. In this study, we investigate the effects and relative importance of bottom‐up, top‐down, and physical forcing during changing climate conditions on ecosystem regulation in the Southern California Current System (SCCS) using a generalized food web model. This statistical approach is based on nonlinear threshold models and a long‐term data set (~60 years) covering multiple trophic levels from phytoplankton to predatory fish. We found bottom‐up control to be the primary mode of ecosystem regulation. However, our results also demonstrate an alternative mode of regulation represented by interacting bottom‐up and top‐down forcing, analogous to wasp‐waist dynamics, but occurring across multiple trophic levels and only during periods of reduced bottom‐up forcing (i.e., weak upwelling, low nutrient concentrations, and primary production). The shifts in ecosystem regulation are caused by changes in ocean‐atmosphere forcing and triggered by highly variable climate conditions associated with El Niño. Furthermore, we show that biota respond differently to major El Niño events during positive or negative phases of the Pacific Decadal Oscillation (PDO), as well as highlight potential concerns for marine and fisheries management by demonstrating increased sensitivity of pelagic fish to exploitation during El Niño.
