BACKGROUND Blunted nighttime blood pressure (BP) dipping is prognostic of cardiovascular morbidity and mortality. This relationship may be stronger among women than men. The present study hypothesized that coronary artery disease (CAD) and advancing age would be associated with reduced BP dipping in postmenopausal women. The effects of daytime physical activity and nighttime sleep quality on BP...

background: diabetic patients have a higher prevalence of non-dipping pattern in blood pressure (bp) than general population. non-dipping arterial pressure pattern is associated with increased cardiovascular risk. the objective of this study was to investigate the association between the clinical and paraclinical characteristics of the diabetic patients with circadian bp variability. m aterials...

OBJECTIVE The lack of nocturnal decline in blood pressure (BP) is associated with an increase in cardiovascular events. Restless leg syndrome (RLS) is an uncomfortable feeling in which the patient wants to budge the legs with ache in the legs. RLS also increases the hypertension and cardiovascular risk. In this study, we aimed to evaluate the relationship between dipping and non-dipping blood p...

the effects of different sources of carbon, nitrogen and some of trace elements on cultivation of bacillus thuringiensis h14 were studied. glucose, glycerol, sodium acetate, (nh4)2so4, corn steep liquor, yeast extract, hydrolyzed casein, ca2+, mg2+ and mn2+ were the main parameters evaluated by plackett-burman statistical method. all elements have insignificant effect on germination while spore...

Unlike land mining, the safety of seabed mining is seriously threatened by an overlying water body. In order to ensure subsea projects, it great importance understand failure characteristics and influencing factors strata deformation. Focusing on Sanshandao Gold Mine, a typical submarine deposit in China, geomechanical model testing numerical simulations were carried out. The results show that ...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...

in exploration seismology, migration refers to a multi-channel processing step that attempts to spatially re-position events and improve focusing. before migration, seismic data is usually displayed with traces plotted at the surface location of the receivers and with a vertical time axis. this means that dipping reflections are systematically mispositioned in the lateral coordinate and the ver...

Mechanical drift is a long-standing problem in optical microscopy that occurs in all three dimensions. This drift increasingly limits the resolution of advanced surface-coupled, single-molecule experiments. We overcame this drift and achieved atomic-scale stabilization (0.1 nm) of an optical microscope in 3D. This was accomplished by measuring the position of a fiducial mark coupled to the micr...

We address the problem of distinguishing between two sources of disagreement in annotations: genuine subjectivity and slip of attention. The latter is especially likely when the classification task has a default class, as in tasks where annotators need to find instances of the phenomenon of interest, such as in a metaphor detection task discussed here. We apply and extend a data analysis techni...
