results long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. conclusions quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier. materi...

These recommendations were developed by the Advisory Committee for Elimination of Tuberculosis, CDC staff, and public health consultants. They describe tuberculosis control activities appropriate for nursing homes and other facilities providing long-term care for elderly persons. Such facilities include long-term-care wings or units in hospitals, adult foster-care homes, board and care homes, a...

abstract background: the gamma knife radiosurgery (gkr) is an established management option for cerebral ar-teriovenous malformations (avms). therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. methods: radiosurgery was performed between february 2003 and april 2010 at kamraniye day clinic, teh-ran, iran, usi...

noise is considered as one of the most severe sources of environmental and workplace constraints. many noise effects are well known on immune function, hormonal levels, cardiovascular and respiratory systems. in this study, our aim is to evaluate the effects of traffic noise exposure on basal and stimulated gastric pepsin secretion. 48 male rats were exposed to traffic noise (86 db) for a short...

Let the mixed linear regression model when mean value parameters satisfy some linear constraints be under consideration. To detect rough errors or mistakes (outliers) in observations needs a knowledge of a covariance matrix of an observation vector. If unknown variance components occur in it, some problems arise how to recognize, whether estimates or approximations of them can be used instead o...

The Government and its agencies have seriously overestimated the impact of the specialist schools programme on educational attainment. The substantially higher exam scores achieved on average by schools with specialist status are due primarily to sample selection bias and not to any benefits flowing from subject specialisation itself. A fixed effects model is used on the panel of maintained sec...

two omega-3 fatty acids including docosahexaenoic acid (dha) and eicosapentaenoic acid (epa) are essential for the physiologic function of neuronal cell membrane. normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine-in...
