  Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...

In this paper, we prove the existence of the solution for boundary value prob-lem(BVP) of fractional dierential equations of order q 2 (2; 3]. The Kras-noselskii's xed point theorem is applied to establish the results. In addition,we give an detailed example to demonstrate the main result.

Customized birth weight charts that incorporate maternal characteristics are now being adopted into clinical practice. However, there is controversy surrounding the value of these charts in the prediction of growth and perinatal outcomes. The objective of this study was to assess the use of customized charts in predicting growth, defined by body fat percentage, and perinatal morbidity. A total ...

BACKGROUND A major problem of the first moments of childbirth, especially in "prolonged labor," is perinatal asphyxia which necessitates neonatal resuscitation. This study aimed at evaluating the alert line of the partogram in recognizing the need for neonatal resuscitation 20-30 s after delivery. MATERIALS AND METHODS 140 full-term pregnant women were kept under surveillance through using a ...

Preterm delivery is the main cause of perinatal morbidity and mortality throughout the world. Many complications such as neonatal intraventricular hemorrhage, cerebral palsy and high cost have increased the importance of preterm delivery therefore, it is important to detect high risk women early in pregnancy in order to prevent this problem. All of the methods used for preterm deliv...

OBJECTIVE To determine the predictive accuracy of the combined panels of serum human tissue kallikreins (hKs) and CA-125 for the detection of epithelial ovarian cancer. METHODS Serum specimens collected from 5 Indonesian centers and 1 Vietnamese center were analyzed for CA-125, hK6, and hK10 levels. A total of 375 specimens from patients presenting with ovarian tumors, which include 156 benig...

Phasic dopamine signaling participates in associative learning by reinforcing associations between outcomes (unconditioned stimulus; US) and their predictors (conditioned stimulus; CS). However, prior work has always engendered these associations with innately rewarding stimuli. Thus, whether dopamine neurons can acquire prediction signals in the absence of appetitive experience and update them...

OBJECTIVES To investigate the value of T-wave inversion after premature ventricular complexes (PVCs) for the prediction of hypertensive patients with a likelihood of ischemic heart disease (IHD). PATIENTS AND METHODS Ambulatory 24-hour ECG, ambulatory 24-hour blood pressure (BP) recording, echocardiography, treadmill exercise ECG test and thallium-201 scintigraphy were performed for 210 hyper...
