The initial step in an infectious disease is often adhered to and colonization of host tissue surfaces. Staphylococcus aureus, which is a major human and animal pathogenic organism, has been shown to bind to several host matrix proteins and plasma proteins, such as fibronectin, fibrinogen, collagen, elastin, laminin, prothrombin, thrombospondin, bone Sialoprotein and vitronectin . For each of these binding functions, a corresponding surface-associated protein has been identified. The existence of an S. aureus extracellular matrix binding protein with broad specificity that is capable of binding several extracellular glycoproteins has also been reported. The role of some of these proteins in the pathogenesis of staphylococcal infections has been shown in animal models. Most S. aureus strains bind to fibronectin and two highly homologous fibronectin binding proteins (FnBPs), and their corresponding genes (fnbA and fnbB) have been identified. Mutants defective in either of the two genes adhered equally well to fibronectin-coated surfaces in vitro, while a double mutant was completely unable to adhere, indicating that both genes are expressed and contribute to fibronectin binding. That’s why we have chosen fibronectin possible target for vaccine design against Staphylococcus aureus. This proposed target protein for vaccine contained four coils and three strands.

Infertility has a strong and negative impact in several areas of the individual’s life. The infertile women may lose prestige in society, may develop a low self-esteem, and may lose hope for the future. This study compared psychosocial responses in 90 infertile women and normal women. An ex post facto design was used. The subjects of the present study were infertile women in an infertility treatment center in Ahwaz, Iran. Women selected by randomly sampling. The women completed the psychosocial responses. Data were analyzed using analysis of variance. Differences were found between the groups on the psychosocial responses (self-image/self-esteem, guilt/blame, sexuality problems, and interpersonal relationship).

This geophysical investigation of groundwater is aimed at delineating the aquiferous units around the western part of the Lower Imo River Basin by determining their depths, thicknesses, resistivities and the potential borehole depth at various locations within the area employing the technique of Vertical Electrical Sounding (VES) using the Schlumberger array. Twenty two sounding stations were established. Four to six geo-electric layers comprising the top soil, clayey sand, dry sandstone, saturated sandstone, shaley sand and sandy shale were delineated with the later usually occurring as the last layer. The third and fourth layers underlying dry sandstone form the aquiferous unit. This unit was found to have an average resistivity value range of 10.7–6060?m and an average thickness of 32 m. Longitudinal Conductance increases towards the Southeast with a high closure around Umuduru Egbe Aguru. Conversely, Transverse Resistance increases towards the Northwest with a very high closure around Dikenafai and Mgbee axis. These confirm the difficulties often experienced during ground water exploitation in these localities. The Northern part of the study area has high thickness of aquifer units ranging from 50-80m. Similarly too, high depth to water table and consequent high possible Total Drill Depth (TDD) were mapped within the Northern part of the area. The reverse is the case for the South being dominated by the highly prolific Benin Formation. It was advised that care ought to be taken in drilling and casing at shallow aquiferous areas to maintain proper sanitary condition so as to reduce the risk of groundwater contamination.

Leptospirosis continues to be a challenge to health worldwide, among farmers, municipal workers etc. Despite widespread implementation of effective therapy, leptospirosis has not been eliminated or keeping under the control. The outbreaks occurring every year with increasing mortality during the flood and other water oriented natural calamities. Identification of patients with leptospirosis is challenging among the clinicians, due to misdiagnosing or under diagnosing, including non consideration of PUO cases to leptospirosis. Children who develop leptospirosis continue to be especially disadvantaged, with rates of late diagnosis and mortality remaining high. Leptospirosis is not a specified disease in the Millennium development goals, but severity and multiple organ dysfunctions to multiple organ failure induce the researchers and clinicians to concentrate for education and level of improvement of the patient care including immediate therapy. We review data and make recommendations for research on diagnosis, treatment and prevention such us further use of molecular analysis of Leptospira interrogans genome, formulation of newer vaccines and administration of doxycycline chemoprophylaxis to contacts. We also suggest developing the tools for early diagnosis and detection of infection and organ damage and formulation of strategies to manage the chronic complications of leptospirosis such as hepatospleenomegaly, renal failure, respiratory distress and neuropathy.

This study offers a brief overview of the export and import of wood based panelin India. The statistical parameters such as descriptive analysis, trends, graph and regression analysis have been computed to understand the nature of wood based panels export and import with top 25 countries on the basis of five year assessment, which is accounts 87.7% (1997-1998 to 2001-2002), 89.5% (2002-2003 to 2006-2007) and grow to 91% (2007-2008 to 2011-2012). The result of regression analysis demonstrate high R20.86 in export and 0.97 in import with correlated GDP, FDI and PC-NDP. The wood based panel’s viz. veneers, plywood, fibre boards, particle boards have also been examined for their trends.

In recent years, the human body as an important topic in contemporary sociology has been studied. Therefore, the body is very important and has attracted the attention of many researchers. One of the issues raised in this area, is today in body management among youth (boys and girls) are quite common and popular because of body management, through actions and behavior like choosing clothes, coat appearance, body configuration, type hobbies, sports, diet and ... Are expressed. Given the importance of the management body of the youth in the present study sought to examine social factors affecting the management body of the young people were in Yasuj. In our population of young people 15 to 29 years is in Yasuj and a sample of 353 people were selected for the study sample. To examine the relationship between body by the same token, religious, cultural, economic status, and age as independent variables and the dependent variable pay as a management body. The results indicate a significant relationship between the independent and dependent variables in research.

Modern shipping, with increased number of vessels, faster, more sophisticated, expensive, specialized, complex operation, governed by comprehensive rules and regulations as per national and international authorities, is a vital industry carrying 90% of world trade. Although modern technology and modern navigation equipments contributed more efficient marine transportation than before but injury and fatality statics indicate that shipping remains a high risk industry. This study outlines the classification, types and commonly prevalent errors in shipping operations. Study concludes that qualification, training and development of crew members as one of the key concerns in the effort to achieve higher safety standards aboard ship.

Past shapes the future. Knowledge of the past experience has always been a good guide of understanding today and future. Related to this fact, modern Foreign Language Learning and Teaching (henceforth FLLT) and technology have been commonly identified with computer and internet technologies due to the popularity of computational technologies since 1960s. However, before 1960s, technology and FLLT were also bound together as FLLT after 1800s has always paced parallel to the technological inventions. The rapid development of approaches, techniques, and methods has been accompanied by technology, and many technologies have been adapted to FLLT. Beyond any doubt, modern FLLT today is shaped by computational technologies. Nevertheless, the issue of FLLT technology before computers is still vague and blurred. This obscurity dims the view on the relation between modern technologies and FLLT and causes many technological trial and errors today. This study embraces the invention of the computers as a turning point and scrutinizes BC and AD of technology in FLLT by focusing on the impact of technological innovations on FLLT within 1800- 1957 and establishes correlations of past and present experience for better future insights.

During the synthesis of bis - benzothiazols via condensation of 2-aminothiophenol and oxalic, malonic acids an interesting product was obtained during the workup of the reaction products, which upon characterization by spectroscopic methods was found to be bis-(2-aminophenyl) disulfide (NH2PhSSPhNH2).

A modern man is different from his ancestors in different perspectives. Though the developments have created new problems and crises ahead of him, development in technology and science has brought up welfare , and has changed the life fundamentally. This study was aimed at investigating the base of spiritual crises and problems in a qualitative manner. Some of the problems ahead of us as human beings are: identity crisis, knowledge crisis, moral and psychological crisis. In this regard, Rumi (Moulana) is one of those people who have referred to all of human beings in all the times. Using the language of flute, he has warned the unawares and has guided them toward the road of bliss. In reaching the aims of the study, the crises were first defined. Later, the solution was offered from Rumi’s view point.
