Reaserch on phytoremediation of cadmium contaminated water by three submerged macrophytes

The study is about the growth and cadmium′s restoration effect of three submerged macrophytes(Ceratophyllum demersum L.,Elodea nuttallii and Vallisneria natans)in different pH and cadmium.The result shows that,three submerged macrophytes can all tolerate the pollution of cadmium in a certain concentration range,and eliminate cadmium of the water to different degree.Ceratophyllum demersum L.and Elodea nuttallii have strongest elimination ability of cadmium under pH 8.5 or 15 μg/L cadmium.Vallisneria natans has strongest elimination ability of cadmium under pH 7.5 or 10 μg/L cadmium.Among these living submerged macrophytes,Elodea nuttallii has the strongest tolerate and elimination ability of cadmium(up to 92%),then Ceratophyllum demersum L. (up to 90%),and Vallisneria natans(up to 66%). The elimination ability of the 3 submerged macrophytes' powder is more obvious than its living form,Elodea Canadensis's powder has the strongest elimination ability of cadmium(up to 95%),then Ceratophyllum demersum L. 's powder(up to 93%),and Vallisneria natans's powder(up to 88%). But the elimination ability of cadmium by Vallisneria natans's powder is less vulnerable to the pH and the cadmium concentration(range between 81% and 88%). The three submerged macrophytes adaptation scope very broad,efficient and pollution-free,they could be successfully used for heavy metal removal from waste-water containing cadmium.
Sex‐biased gene expression during the adult stage of the Indian meal moth Plodia interpunctella

Sexual dimorphisms are primary regulated by sex‐biased gene expression. In the present study, using real‐time polymerase chain reaction, we determined the expression profiles of nine genes associated with development, metabolism, stress, and defense throughout adulthood of the Indian meal moth Plodia interpunctella, a global pest of stored food products. Most genes were differentially expressed in a sex‐biased manner during the adult lifespan of the moth. Expression of the heat shock protein genes hsp25 and hsp90 and the antioxidant gene thioredoxin peroxidase (Tpx) was highly female biased, whereas the expression of a gene related to host development (ecdysone receptor [EcR]) and two genes associated with immunity (β‐glycan recognition protein [βgrp] and prophenoloxidase [ProPO]) was male biased. In contrast, the expression of hsp70, glucose‐regulated protein 78 (grp78) and ultraspiracle (USP) was not sex biased. The results of the present study provide important insights into the role of sex‐biased genes in the physiology and behavior of P. interpunctella.
FEMALE MATE‐CHOICE BEHAVIOR AND SYMPATRIC SPECIATION

Abstract Many models have investigated how the process of speciationmay occur in symparty. In these models, individuals are either asexual or mate choice is determined by very simple rules. Females, for example, may be assumed either to compare their phenotype to that of a potential mate, preferring to mate with similar males (phenotypematching), or to possess preference genes that determine which male phenotype they prefer. These rules often do not reflect the mate‐choice rules found in empirical studies. In this paper, we compare thses two modes of female choice with various types of sexual imprinting. We examine the efficacy of different mate‐choice behavior in causing divergence in male traits under simple deterministic one‐locus population genetic models as well as under polygenic, individual‐based simulations based on the models of Dieckmann and Doebeli (1999). We find that the inheritance mechanism of mate choice can have a lare effect on the ease of sympatric speciation. When females imprint on their mothers, the result of the model is similar to phenotype mathching, where speciation can occur fairly easily. When females imprint on their fathers or imprint obliquely, speciation becomes considerably less likely. Finally, when females rely on preference genes, male trait evolution occurs easily, but the correlation between trait and preference can be weak, and interpreting these results as speciation may be suspect.
Diabetic ketoacidosis; Annual Incidence and Precipitating Factors at King Abdulaziz Medical city, Jeddah

Introduction: Diabetes is a recognizable and major health burden in Saudi Arabia. The incidence of Diabetes Mellitus Type 1 (DM1) reached 109.5 per 100,000 child and adolescent. One of the major life-threatening complications of DM1 is Diabetic Ketoacidosis (DKA). This study aims to estimate DKA incidence among DM1 patients and possible risk factors. Methods: Retrospective review for DM1 patients at King Abdul-Aziz Medical City, and who was presented with DKA during the past six and half years. Results: Three hundred and fifty DM1 patients were included and (72) experienced DKA during study period. The average annual DKA onset was (6.2%). Mean age was (22.82 ± 5.567) years, and females constituted (66.7%) of this group. Poor medication compliance was the commonest risk factor associated with DKA, and this relationship was found significant (P-value 0.003). Out of the total DKA sufferers, (28) patients experienced recurrent or multiple DKA episodes, and those had higher HbA1C levels (11.7 ± 2.9 Vs 12.4 ± 3.3). Patients who had multiple DKA episodes reported less visits to the diabetes educator when compared to the single DKA group. (On average (9) Vs (11) per year). Conclusion: DKA was found relatively uncommon among our DM1 patients, and usually seen in young females with poor medication compliance. More comprehensive education on DKA is needed to protect against life threatening complications.
Basic mechanisms of epilepsy

amplification of CDK4. This indicates that disruption of the RB I pathway is directly related to astrocytic tumour progression. Amplification of the EGFR gene was not observed in A, was unusual in AA (8%) but common in GB (33%). Loss of wild type PTEN occurred in one AA (3%) but was very common in GB (47%) and could be found together with all combinations of the other genetic abnormalities. Molecular diagnosis as well as molecular therapeutic approaches must consider the various ways cellular mechanisms are disrupted.

A Brief Study of Dimensionality Reduction for Mass Spectra Classiﬁcation

Mass spectrometry is a relatively new ﬁeld of study, so, for now, its data processing pipelines look fragmented and challenging. This paper covers the last two steps of such pipelines: generation of features by peak alignment and classiﬁcation of spectra. A crucial machine learning issue is that, typically, the length of a feature vector signiﬁcantly exceeds the number of spectra in a sample. We propose some basic ideas for dimensionality reduction based on peaks aggregation and evaluate its eﬃciency by intensive computational experiments.
In Vitro and In Sacco Evaluation of Rations Supplemented with Varying Levels of Dietary Bypass Fat in Sheep

Four iso-nitrogenous rations (12% CP) with 0, 5, 10 and 15% calcium soap of red palm oil, prepared in the laboratory, were formulated using sorghum straw and concentrate feed ingredients and evaluated in vitro and in sacco. Average in vitro dry matter digestibility (IVDMD), in sacco DM disapperance and ‘effective degradable dry matter’ (EDDM) of the rations were similar. Further, in vivo studies have been suggested.
Protein kinase CK2 in DNA damage and repair

Abstract: Protein kinase CK2, formerly known as casein kinase 2, is a ubiquitously expressed serine/threonine kinase, which is absolutely required for cell viability of eukaryotic cells. The kinase occurs predominantly as a tetrameric holoenzyme composed of two regulatory α or α' subunits and two non- catalytic β subunits. It is highly expressed and highly active in many tumour cells. The proliferation promoting as well as the anti-apoptotic functions have made CK2 an interesting target for cancer therapy. It phosphorylates numerous substrates in eukaryotic cells thereby regulating a variety of different cellular processes or signalling pathways. Here, I describe the role of CK2 in DNA damage recognition followed by cell cycle regulation and DNA repair. It turns out that CK2 phosphorylates a number of different proteins thereby regulating their enzymatic activity or platform proteins which are required for recruiting proteins for DNA repair. In addition, the individual subunits bind to various proteins, which may help to target the kinase to places of DNA damage and repair. Recently developed pharmacological inhibitors of the kinase activity are potent regulators of the CK2 activity in DNA repair processes. Since DNA damaging agents are used in cancer therapy the knowledge of CK2 functions in DNA repair as well as the use of specific inhibitors of CK2 may improve cancer treatment in the future.
Impacts of invasive ants on native ant communities (Hymenoptera: Formicidae)

The most commonly documented consequence of alien ant invasions is the displacement and local extinction of native ant species. However, several processes may lead to low native ant diversity in the presence of non-native species. Invasive ants may, indeed, competitively exclude native ants. Conversely, invasive ants may not be able to spread into diverse, competitively dominant native ant communities. Finally, complementary distribution of invasive and native ants may be non-interactive and instead driven by divergent responses to heterogeneous environmental factors. Here, I review studies of non-native ants that have associated negative impacts on native ant communities, discuss how native ant communities are reorganized in invaded habitats, summarize reports of vulnerable and resistant ant species, and examine evidence for mechanisms of reduced native ant diversity. Invasive ants are often, but not always, associated with lower native ant abundance, reduced species diversity, and randomly structured, homogenized native ant communities. Native ants are unlikely to co-occur with invasive ants 1) in habitats with environmental conditions suitable to and / or modified for the invader, 2) during the height of an invasion when an invading species is at its peak density, 3) when native ants are ecologically similar to the invading species and lack potent chemical defenses. Little evidence supports the biotic resistance hypothesis for native ants. Instead, suitable environmental conditions are primary determinants of the establishment and success of invasive ants. While invasive ants generally thrive in disturbed areas, many studies document the spread of invasive ants into undisturbed habitats and support the notion that invasive ants can drive declines in native ant diversity. More experimental studies are needed to explicitly test the importance of interactive and noninteractive processes in determining the spread of invasive ants and their impacts on native ant diversity.
γ‐Hydroxybutyrate Model of Generalized Absence Seizures: Further Characterization and Comparison with Other Absence Models

Summary: γ‐Hydroxybutyrate (GHB) produces a constellation of EEG and behavioral events that respond selectively to antiabsence antiepileptic drugs. The GHB‐induced seizure was quantitated in the presence of three other absence seizure models: pentylenetetrazole, systemic penicillin, and the flash evoked afterdischarge (FEAD). Penicillin and pentylenetetrazole produced a significant prolongation of GHB‐induced seizure in a dose‐dependent fashion. This po'tentiation of GHB seizure was observed when these compounds were given either before administration of γ‐butyrolactone (GBL), the prodrug of GHB, or at the onset of GHB‐induced seizure. Photic stimulation given in a manner to produce FEAD also resulted in a significant prolongation of GHB‐induced seizure. All of these maneuvers lowered the threshold to GHB seizure, but none interfered with the brain kinetics of GHB in the animals treated with GBL. Ethosuximide pretreatment significantly shortened the GHB seizure and overcame the potentiating effect of penicillin and pentylenetetrazole in this model. These data confirm the GHB‐treated animal as a model of generalized absence seizure. The GHB model meets appropriate criteria for an absence seizure model and compares favorably with other models of absence currently in use.

On The Use Of Quantile Regression Technique For The Analysis And Estimation Of The Determinants Of Wage Differential Of Workers In Nigeria

Linear regression can be described as representing the dependent variable as a linear function of one more independent variable(s), subject to random disturbance error. It estimates the mean value of the dependent variable for given levels of the independent variables. For the type of regression in which we may want to understand the central tendency in a dataset, the use of ordinary least square (OLS) is of paramount importance. OLS, however, losses its importance the moment an attempt is made to go beyond the median value or towards the extremes of a dataset. Quantile Regression was therefore introduced as a non-parametric method for modelling a variable of interest as a function of covariates. By estimating the conditional quantiles rather than the mean, it gives a more complete description of the conditional distribution of the response variable than least square regression, and is especially useful in certain types of applications. Quantile regression has appeared as an alternative to least squares in a wide range of applications. When the centre of the conditional distribution of a response variable Y, given a covariate vector X, is under investigation, median regression provides a consistent estimator of the conditional median without assuming a specific form for the conditional distribution. When other conditional quantiles, for example, the lower or upper tail of the conditional distribution, are of interest, quantile regression provides a way to directly estimate the interesting quantiles without assuming that such Abstract: In this study, we attempted to analyze the determinants of wage disparity by applying quantile regression technique. The significant effect of factors influencing wage disparity such as gender, education, age and job tenure was carried out using Quantile Regression Technique. The stratified random procedure was used to select a sample data of one thousand one hundred and eleven (1111) workers from the Federal University of Technology Akure, Nigeria (FUTA). Strata and Gretl statistical packages were used for the implementation of the quantile regression procedure through the use of quantile (θ) values 0.05, 0.25, 0.5, 0.75 and 0.95. We found out that wage is positively related to age, gender and education at all quantiles. However wage is negatively related to job tenure at middle and higher quantiles but positively related to job tenure at lower quantiles, but not statistically significant at lowest quantile. This implies that inequality in educational attainment, age, gender differences and job tenure produce significant effect on monthly wage disparity among workers.
Tryophagus putrescentiae induces inflammatory cytokine secretions from the human cell lines THP‐1 and EoL‐1 cells

The present study aimed to identify the roles of the storage mite Tyrophagus putrescentiae (Tp) in relation to human skin diseases, such as atopic dermatitis. We examined the effects of T. putrescentiae extracts (TpE) on the secretion of inflammatory cytokines and their mRNA expression in human immune cells. Human monocytic THP‐1 and eosinophilic EoL‐1 cells were challenged with TpE and the inflammatory cytokines, interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), and monocyte chemotactic protein‐1 (MCP‐1) secreted in culture supernatant were analyzed using an enzyme‐linked immunosorbent assay (ELISA). The mRNA levels in the cell cultures were also measured via reverse transcriptase‐polymerase chain reaction (RT‐PCR). In the THP‐1 cells, the TpE significantly induced the secretion of IL‐6, IL‐8, and MCP‐1 in a time‐ and dose‐dependent manner. It also stimulated increases in the expression levels of the IL‐6, IL‐8, and MCP‐1 mRNA. However, while the TpE induced IL‐8 and MCP‐1 mRNA levels in the EoL‐1 cells, it did not induce IL‐6 expression. Using Western blot analysis, we confirmed the activation of extracellular signal‐regulated kinase (ERK), a member of the mitogen‐activated protein kinases (MAPKs), in response to TpE challenge of the THP‐1 cells. Collectively, our results show that TpE challenge elicits inflammatory response in the human monocytic THP‐1 and eosinophilic EoL‐1 cells, and it induces increased production of the inflammatory cytokines IL‐6, IL‐8, and MCP‐1.
A Report on Nonstationary Response of Nonlinear MDOF Systems using Equivalent Linearization and Compact Analytical Model of the Excitation Process by Baris Erkus

This report is a fruit of the effort to learn the fundamental concepts of random processes and random vibrations theory under the course “CE790, Directed Research”. The boundaries, however, extended to more advanced topics such as equivalent linearization and nonstationary responses. The goal was to review the paper by Smyth and Masri on nonstationary analysis of nonlinear structures and implement one of the examples given in that paper using Mathematica. The main challenge was not the main theory as may be expected. Indeed, the paper is very clear to understand and the theory is easy to follow. The challenge was the implementation in Mathematica. The inefficiency of Mathematica in writing highly numerical codes was extremely restricted the author from further progress. The preparation of this report took more time than expected, however, the author has gained a lot of knowledge on the topic under the supervision of Prof. Dr. Sami F. Masri for a stand-alone research that will be carried out later. This report consists of two parts: The first part is a brief review of theory of random processes. The explanations are straightforward and very helpful for a review. The second section is the review of the theory explained in the aforementioned paper. Although it looks similar to the original paper, some parts uses different nomenclature and, details of some of the sections are added. In addition to the original theory, a simplification of the method proposed is given. This simplified approach is easier to implement than the original approach. Finally a Mathematica code is given as an example of the application of the method. The only benefit of Mathematica was the use of built-in approximation function, namely “Fit”. Other than that, the differential equation solver of Mathematica was not able to solve the equations obtained and, therefore, a Runge-Kutta solver is coded. At the time of preparation of this document a new version of Mathematica (Version 5.0.0) is released. This version is capable of solving multi single degree differential equations using Runge-Kutta method. However, it may be useful to use other programming languages such as Matlab for the numerical computation to avoid the other problems of Mathematica, which were explained in this report. The author wish to thank to Prof. Masri, for his supervision. The work was extremely helpful to the student to understand the concepts that appear very frequently in the field, and it will definitely be extended in the future.

Variations in the Blood Chemistry of Turtles under Active and Hibernating Conditions

SHILE many observations have been made on the habits and activities of turtles at all seasons of the year, few studies have been made of their physiological adjustments. By an investigation of the hematology of turtles it was believed that an understanding of the manner in which the blood aids in physiological adjustments to the environment could be gained. In order to investigate this problem, studies were made on the blood chemistry of two species of turtles. These two species were the terrestrial box turtle, Terrapene carolina carolina, and the aquatic red-eared turtle, Pseudemys scripta elegans. Variations in amounts of
