Pajouhan Scientific Journal , 2013,
Abstract: Introduction: Toxoplasmosis is a most common parasitic infection in humans and animals, it has two acute and chronic phases that related to IgM and IgG, respectively. This prevalence is affected by different variables, so determination of the prevalence of serum IgG and IgM antibodies against Toxoplasma in terms of these variables like age, occupation and education level is so important.Material and Methods: This descriptive-analytic cross sectional study was done on 350 pregnant women referred to health - Therapeutic centers of Hamadan city. After obtaining informed consent from volunteers, their serum samples were tested by IgG ELISA and IgM ELISA methods and their associations with age, occupation and education level variables were measured.Results: From total of 350 pregnant women, 105 cases (30%) had anti-Toxoplasma IgG, and 3 cases (2.9%) had anti-Toxoplasma IgM. Antibody titer of IgM with variable age, occupation and education level was not significant, but antibody titer of IgG with these variables was significant.Conclusion: Given the significant association between the disease and age, occupation and education level in pregnant women, it should be provide the necessary training and knowledge about preventiion and avoid of being infected with toxoplasmosis infection.

International Journal of Botany , 2010,
Abstract: Three native strains, identified as Staphylococcus sp., Acinetobactor lwoffii and Enterobacter agglomerans were isolated from crude oil contaminated field and the aim of this research was to select potential soil microbial strain that could be effective in the bioremediation of crude oil compounds. Crude oil degradation performed by the isolates incubated in the shake flask culture and analysis of the results address that Acinetobactor lwoffii, accelerated cleanup most effectively, degrading oil sludge by a total of 93.78% in compare to Staphylococcus sp. (17.39%) and Enterobacter agglomerans (16.49%). Furthermore enhanced biodegradation potential of the isolates were studied by adding Mn and Cu and results indicated that supplemented metal increased degradation of crude oil products. In the present study, three bacterial strains AS1, AS2 and AS3 were termed and isolated through long cultivation with crude oil as the single carbon source. The three strains were identified based on the morphology of their colonies with physiological and biochemical characteristics. In addition, the characterizations of soil where the presence of these strains were carried out. The total CFU count ranged from 2x106 to 6x106 and total viable bacteria at 32°C ranged from 2.2x103 to 5.6x103 in various soil sample collected in random from contaminated site. The strains had broad degradation capacities and the present remediation monitoring confirmed the effectiveness of Acinetobactor lwoffii has one of the potential native microbes for remediation of crude oil soil.

International Journal of Botany , 2010,
Abstract: The study reports the ethnobotany and threats to wild edible plants in Assam province of India, which is considered as a mega-biodiversity centre under two important biodiversity hotspots viz., Indo-Burma and Himalaya. The people living in remote/forest area still depend upon to a great extent on the indigenous system of medicine/cultivation. Here, we summarize the information derived through meta-analysis and present an updated estimate of the wild edible, medicinal and threatened plant species that has been reported by wide variety of taxonomic groups. Out of 3895 plant species nearly 7.34% were used as wild vegetables, fruits and ethno-medicines. In over all, 286 edible wild plant species estimated belong to 93 families and 192 genera are hitherto unknown or less known to the world. Of these, 150 species were reported to be used in traditional system of medicine. The estimates revealed that as many as 27 species were in the list of red data book, CITIES and IUCN red list threat categories due to over exploitations and these plants need a strong conservation and protection management.. In the present investigation, the work that has been reported and the potential of ethno-botanical studies with particular reference to biodiversity conservation of the important wild edible plant species have been highlighted in study area.
Performance Model for a Conservative Distributed Simulation Environment Using Null Messages to Avoid Deadlock
Hemen Patel,Syed S. Rizvi,Laiali Almazaydeh,Aasia Riasat
International Journal of Computer Science & Information Technology , 2010,
Abstract: A conservative distributed simulation requires all logical processes (LPs) to follow the causality constraint requirement. This implies that all event-messages are processed in strictly timestamp order.Apart from the timestamp of each event generated by LPs, synchronization between all LPs is the second most important requirements. Finally, there must not be a deadlock in the distributed environment. A deadlock may occur when there is no events present in the queue of LP. In such case, to avoid deadlock,Chandy-Misra-Bryant presented an algorithm called Null Message Algorithm (NMA) [3]. These null messages are passed as an event-message to other LPs and it stored in one of queues of LPs. This nullmessage indicates that till the time stamp of that null message, all other events in the queue which have lesser time stamp than null message’s time stamp are safe to process. It means that there won’t be any arrival of any events from that logical process until current simulation time is equal to the time stamp of the null message. With the time stamp of the null message, a Lookahead value is added to the time stamp of that null message. This Lookahead value can be measure on certain kind of parameters such as delay to transmit a message, propagation delay, etc. therefore, calculating value of Lookahead is the most important part as Lookahead value affects the performance of the conservative distributed event simulation. Proper value of Lookahead can reduce the number of null messages which decreases thetraffic of the network. In this paper, we demonstrate some calculation on the Lookahead which shows the performance of the distributed event simulation.

Incorporation of Fundamental Objectives and Directive Principles of State Policy in the Constitutions of Emerging Democracies: A Beneficial Wrongdoing or a Democratic Demagoguery?  [PDF]

Abstract: It is trite that sovereignty belongs to the people. Thus, the realization that the donors of power: The people or the citizens have some rights against the state, and the need to respond to their desires and demands by satisfying them, ensured the enshrinement of citizens’ rights in the constitution as either fundamental rights or fundamental objectives and directive principles of state policy. This paper examined the incorporation of the second class of rights in the constitutions of developing democracies such as Nigeria, Ghana and Sierra Leone with a view of searching the rationale and jurisprudence of their incorporation in view of their non-enforceable status. It found that the continuous non-enforceability of fundamental objectives and directive principles of state policy in the constitutions of these countries render them more of a democratic demagoguery incapable of furthering the aims of good governance and sustainable development anchored on the social contract between the government and the governed. The paper however recommended that Nigerian court should adopt the posture of judicial activism in interpreting the rights contained in Chapter two of the constitution to bring them in consonance with the civil and political rights, which are enforceable.
GENE THERAPY: THE FOREFRONT OF MEDICINE

Wayamba Journal of Animal Science , 2012,
Abstract: The concept of transferring genes to tissues for clinical applications has been discussed for nearly half a century, but the ability to manipulate genetic material via recombinant DNA technology has brought this goal to reality. While originally conceived as a way to treat life-threatening disorders (inborn errors, cancers) refractory to conventional treatment, gene therapy is now considered for many non–life-threatening conditions, including those adversely affecting a patient’s quality of life. The lack of suitable treatment has become a rational basis for extending the scope of gene therapy. This manuscript reviews the general methods by which genes are transferred as well as diverse examples of clinical applications (acquired tissue damage, upper gastrointestinal tract infection, autoimmune disease, systemic protein deficiency). Despite some well-publicized problems, gene therapy has made substantive progress, including tangible success, albeit much slower than was initially predicted. Although gene therapy is still at a fairly primitive stage, it is firmly science based. There is justifiable optimism that with increased patho-biological understanding and biotechnological improvements, gene therapy will become a standard part of clinical practice within 20 years

Wayamba Journal of Animal Science , 2011,
Abstract: Present study was conducted to estimate the haemato-biochemical alterations during parasitic infection in donkey (Equus acinus) of Banaskantha district of Gujrat, India. Based on qualitative faecal sample examination, one hundred donkeys were categorized as Group-I and Group-II. Group-I animals were (+)ve for helminthic infection and designated as ‘infected’; whereas, Group-II animals were (-)ve for helminthic infection and designated as ‘uninfected’. Haematological profile revealed significant decrease in haemoglobin (Hb), total erythrocyte count (TEC) and packed cell volume (PCV) in infected animals as compared to uninfected. However, the rise in erythrocyte sedimentation rate (ESR) and eosinophil count in group-I was non significant. Whereas, there was no significant difference (p<0.01) in neutrophil, lymphocyte and monocyte count between the two groups. Biochemical profile indicated increase in the level of cholesterol, creatinine, acid phosphatase (ACP), alkaline phosphatase (AKP), aspertate amionotransferase (AST) and alanine aminotransferase (ALT) in infected animals. In contrast, biochemical analytes viz. glucose, total protein, albumin, globulin, calcium, phosphorus, magnesium and zinc were significantly decreased in infected animals as compared uninfected. Helminth infected animals also exhibited non-significantly lower level of iron, copper, total iron binding capacity (TIBC), triglyceride (TG) and blood urea nitrogen (BUN).The results suggest gross alteration in haemato-biochemical parameters and may form a basis of monitoring parasitic infection in donkey.
