جهت ایجاد روش های جدید و مفید برای درمان و پیشگیری بیماری لیشمانیوز در دهه های گذشته مطالعات زیادی در زمینه واکسن مناسب انجام شده است و اخیرا نقش il-22 در ایجاد حفاظت و مکانیسم دفاع ذاتی، در کنترل عفونت های باکتریال، ویرال، هموستازی و ترمیم بافت ثابت شده است. لذا در این تحقیق اثر سیتوکین il-12, il-22 به همراه پلاسمید کد کننده ژن tsaو lack لیشمانیاماژور در روند بیماری لیشمانیازیس در موش balb/c ب...
This study examines whether language-specific input influences children’s nonlinguistic spatial cognition as they acquire their first language. Recent research on infant cognition has shown that preverbal infants can make a distinction between tight-fit and loose-fit containment relations. This distinction is systematically made in Korean (kkita ‘fit tightly’), but not in English (in). Using a ...
This paper builds a bridge between research on regulatory focus in motivation and classification learning. It tests the hypothesis that a fit between the situational regulatory focus and the reward structure of the task leads to greater cognitive flexibility than a mismatch between situational focus and the reward structure and that the fit between the regulatory focusinduced processing charact...
Article history: Received 17 March 2014 Received in revised form 5 May 2014 Accepted 8 May 2014 Available online xxxx In this invited response, we first note that contrary to the claims of Haier and colleagues, they were not part of the review process for the article Fractionating Human Intelligence. We then expand on the rationale underlying the primary objective of the study, to determine whe...
Decisions are often based on the results of quantitative analysis. To gain confidence in these results, some indication of their quality is needed. Measurement uncertainty, as proposed by the International Organization for Standardization (ISO), is a way to express this quality. Most measurement techniques compare references and therefore need to be calibrated. Usually least squares methods ign...
A controversial area in covariance structure models is the assessment of overall model fit. Researchers have expressed concern over the influence of sample size on measures of fit. Many contradictory claims have been made regarding which fit statistics are affected by N. Part of the confusion is due to there being two types of sample size effects that are confounded. The first is whether N dire...
A long running challenge in both large and small organizations has been aligning information systems services with business needs. Good alignment is assumed to lead to good business results, but there is a need for good instruments to assess strategic alignment and business success in practice. Based on existing information management theories, we develop the I-Fit model and the I-Fit tool. The...
Musical fit, the congruence between music and product leading to improved response, is presented as an explanation of differences in recall of food items from two cultures. Musical fit predicts that, in this case, more Indian food items would be recalled when Indian music was playing, and more Malay food items would be recalled when Malay music was played. The underlining premise of this predic...
Fit testing of tight-fitting respiratory protective facepieces has been in use for some years, but there are still widespread misconceptions and misunderstandings about what a fit test pass actually signifies. Various aspects frequently generate research papers, and there are three relevant ones in this issue (Han and Lee, 2005; Kuo et al., 2005; Vaughan and RajanSithamparanadarajah, 2005). In ...
