BACKGROUND Respiratory variations in plethysmographic waveform amplitudes derived from pulse oximetry are believed to predict fluid responsiveness. The non-invasive pleth variability index (PVI) is a variable based on the calculation of changes in the perfusion index (PI). The aim of the following study was to examine whether the predictive power of PVI depends on different values of PI. METH...
BACKGROUND [18F]fluorodeoxyglucose-positron emission tomography (PET) is emerging as a strong diagnostic and prognostic tool in follicular lymphoma (FL) patients. PATIENTS AND METHODS In a subset analysis of the FOLL05 trial (NCT00774826), we investigated the prognostic role of post-induction PET (PI-PET) scan. Patients were eligible to this study if they had a PI-PET scan carried out within ...
In vaccinia virus-infected cell cultures, cellular protein synthesis was inhibited 50% at 2 hr postinfection (PI) and 80 to 90% by 4 hr PI. Input virus was responsible for this inhibition. Five early proteins, coded for by the viral genome, could be detected at 2 to 3 hr PI. Normally, their synthesis did not continue beyond 6 hr PI, at which time synthesis of a different set of proteins began. ...
Using a hormonally induced susceptibility mouse model to investigate vaginal HSV type 2 (HSV-2) infection, a study was undertaken to determine the efficacy of a plasmid DNA encoding IFN-alpha1 introduced into the vaginal lumen postinfection (PI). Mice infected with HSV-2 intravaginally and treated intravaginally 24 h later with 100 microg DNA encoding IFN-alpha1 showed enhanced survival (10/15)...
در قسمت اول این تحقیق یکسری برهمکنش های بین مولکولی با استفاده از محاسبات nmr مورد بررسی قرار گرفته اند. اثر استخلاف های مختلف در موقعیت های متا و پارا بر داده های nmr در کمپلکس های پیریدن استخلاف دار و هیدروژن فلوئورید مورد مطالعه قرار گرفت. مشخص شد که بین داده های nmr و قدرت الکترون دهندگی استخلاف ها یک همبستگی معناداری وجود دارد. از داده های aim نیز می توان برای پیش بینی داده های nmr استفاد...
West Nile Virus (WNV) is now endemic throughout North America, with annual recurrence dependent upon successful overwintering when cold temperatures drive mosquito vectors into inactivity and halt transmission. To investigate whether avian hosts may serve as an overwintering mechanism, groups of eight to ten House Sparrows were experimentally infected with a WN02 genotype of WNV and then held u...
Deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP) under high central venous pressure (CVP) is often used in aortic arch surgery under cardiopulmonary bypass (CPB). We hypothesized that DHCA with RCP under high CVP causes cerebral vascular compression because of increased perivascular pressure due to extravasation of fluid into intracranial tissue. In a retrospe...
Page 4 PSG Request for Datamining Abstract Parkinson’s disease (PD) has many paradoxes. For example, although smoking is highly associated with cancer and cardiovascular disease, smoking is associated with a much lower risk of PD (which itself is associated with a lower occurrence of cardiovascular disease). Whereas the apolipoprotein E ε4 allele is associated with higher risk of Alzheimer’s di...
Several studies have shown that young children who have experienced early caregiving adversity (e.g. previously institutionalization (PI)) exhibit flattened diurnal cortisol slopes; however, less is known about how these patterns might differ between children and adolescents, since the transition between childhood and adolescence is a time of purported plasticity in the hypothalamic-pituitary-a...
Individuals with severe alpha-1-antitrypsin (alpha1AT) deficiency (phenotype Pi ZZ) are abnormally liable to develop emphysema, but it is uncertain whether those with partial alpha1AT deficiency (phenotypes Pi MS and MZ) are similarly susceptible. This study was undertaken to determine the frequency of the various Pi phenotypes in a working population in Northern Ireland and to compare the perf...
