زمینه و هدف: بیماری کبد چرب غیرالکلی رایج‌ترین کبدی است که در حال پیشرفت بوده بیش از یک‌چهارم مردم جهان را درگیر خود ساخته است. این پژوهشگران معتقدند فعالیت ورزشی استفاده داروهای گیاهی با خواص ضدچربی ضداکسایشی می‌تواند به‌عنوان درمان مکمل، سودمند باشد. بنابراین، هدف پژوهش تعیین آثار هشت هفته تمرین هوازی یا مصرف عرق آرتیشو بر سطوح چربی سرمی آنزیم‌های زنان مبتلا به بود. مواد روش‌ها: بدین‌منظور، 2...

and Hyperinsulinemia To the Editor: QTc dispersion is an important predictor of cardiac mortality. In the Rotterdam Study,1 persons in the highest tertile (.60 ms) relative to the lowest tertile (,39 ms) of QTc dispersion had a 2-fold risk of cardiac death. The Rotterdam Study also confirms that QTc dispersion is larger in diabetic than in nondiabetic persons. QTc duration and QTc dispersion ar...

This paper compares six commonly used QT correction models and three available parameter estimation methods using five indices for QTc evaluation based on real and simulated electrocardiograph (ECG) datasets. The results show that the golden section approach always finds the correction factor making QTc interval uncorrelated to heart rate for all six formulas. However, the correction formulas d...

It has been proposed that some deaths attributed to methadone are related to prolongation of the QTc interval; however, there are no clear recommendations on electrocardiogram (ECG) monitoring in patients undergoing intravenous methadone infusion. This is a report on a patient receiving methadone intravenous patient-controlled analgesia titration for the treatment of chronic pain. Initially, he...

BACKGROUND Aim of the study was to assess QTc interval by a 24-hour ECG recording in a group of HIV-infected individuals with a basal prolonged QTc. The risk factors associated with QTc prolongation and the indices of cardiovascular autonomic control were also evaluated. METHODS A case-control study was performed using as cases 32 HIV-infected patients with prolonged (>440 msec) QTc interval ...

OBJECTIVE Previous data have suggested that a prolonged QTc interval during the first days of life can be associated with some cases of sudden infant death syndrome (SIDS). Analysis of heart rate variability during sleep in future SIDS victims has shown findings compatible with an imbalance in autonomic tone. We hypothesized that some future SIDS infants could have longer QTc intervals during s...

Recently, it has been found that high level of serum uric acid (SUA) is causally related to sudden cardiac death (SCD). We examined the sex-specific associations of SUA with prolonged heart rate-corrected QT (QTc) interval in a general Chinese population.A large sample of 11,206 Chinese research participants aged 35 years and older was recruited from rural areas of Liaoning Province during 2012...
