background: thyroid autoimmunity may be linked to infertility, in both thyrotropin (tsh)-dependent and tsh-independent fashion. the aim of the present study was to assess this presumed reciprocal relationship of thyroid autoimmunity and pregnancy. methods: tsh and antithyroid peroxidase autoantibodies (anti-tpo) were evaluated retrospectively over an eight-year period in 444 greek women who had...

The Dimension Action (DA) model asserts that the visual system is modular, and that each task involves multiple-response mechanisms rather than a unitary-response selection mechanism. The model has been supported by evidence from single-task interference paradigms. We use the psychological refractory period paradigm and show that dual-task performance can also be explained by the DA model. In 6...

In a seminal STOC’95 paper, Arya et al. conjectured that spanners for low-dimensional Euclidean spaces with constant maximum degree, hop-diameter O(logn) and lightness O(logn) (i.e., weight O(logn)· w(MST)) can be constructed in O(n logn) time. This conjecture, which became a central open question in this area, was resolved in the affirmative by Elkin and Solomon in STOC’13 (even for doubling m...

It has recently been demonstrated that a lateralized distractor that matches the individual's top-down control settings elicits an N2pc wave, an electrophysiological index of the focus of visual-spatial attention, indicating that contingent capture has a visual-spatial locus. Here, we investigated whether contingent capture required capacity-limited central resources by incorporating a continge...

It is widely acknowledged that visual input is processed along two anatomically and functionally distinct pathways--a ventral pathway for conscious perception and a dorsal pathway for action control. The present study investigated whether the apparent direct and unmediated processing in the dorsal stream is subject to capacity limitations. Specifically, we tested whether a simple dorsal task of...

conclusions sexual activity in last week of pregnancy might be associated with the onset of labor. therefore, in the absence of complications in term pregnancy, sexual activity can be considered as a natural way to prevent post term pregnancy. background pregnancy is one of the most critical periods in women's lives. sexual relationships change in this period. monitoring of uterine contractions...

extract: whereas pregnancy period in all societies with different cultures cause to physical and emotional and social signs, so fawcett& york (1985), aim to understand and explain types and how of this physical, emotional and social signs in female and their spouses during primary pregnancy periods and post partum conducted a descriptive study. 70 couples for occurrence type determination of ph...

background:   acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua (deciduosis) may occur case: here...
