A nonnegative matrix T = (tij)~,j= 1 is a generalized transitive tournament matrix (GTT matrix) if tii = 0, t o = 1 tj~ for i # j , and 1 ~< t o + tjk + t~ ~< 2 for i, j , k pairwise distinct. The problem we are interested in is the characterization of the set of vertices of the polytope {GTT}n of all GTT matrices of order n. In 1992, Brualdi and Hwang introduced the *-graph associated to each ...

BACKGROUND To determine the antiproliferative effect of gamma-tocotrienol (GTT) treatment on differential protein expression in HepG2 cells. METHODS HepG2 cells were treated with 70 μM GTT for 48 hours and differentially expressed protein spots were determined by two-dimensional electrophoresis (2DE), identified by MALDI-TOF mass spectrometer (MS) and validated by quantitative real-time polym...

This study evaluates interrelationships between carbohydrate and lipid metabolism during oral glucose tolerance tests (GTT) in 65 ischemic heart disease (IHD) males and 69 age-matched healthy controls (age range 45 to 69 years). The frequency of abnormal GTT, usually accompanied by type IV hyperlipoproteinemia, was significantly higher in IHD (37%) than in controls (19%). The mean immunoreactiv...

CONTEXT AND OBJECTIVE Lack of consensus about which screening tests to use for gestational diabetes mellitus (GDM) and difficulties in performing the gold-standard diagnostic test, the 100-g glucose tolerance test (100-g GTT), justify comparison with alternatives. The aim was to compare this with two other screening tests: combined fasting glucose with risk factors (FG + RF) and 50-g GTT. DES...

BACKGROUND Gamma-tocotrienol (GTT), an isomer of vitamin E and hydroxy-chavicol (HC), a major bioactive compound in Piper betle, has been reported to possess anti-carcinogenic properties by modulating different cellular signaling events. One possible strategy to overcome multi-drug resistance and high toxic doses of treatment is by applying combinational therapy especially using natural bioacti...

OBJECTIVE Probiotic and synbiotic products are widely marketed to healthy individuals, although potential benefits for these individuals are rarely studied. This study investigated the effect of daily consumption of a synbiotic yogurt on gastrointestinal (GI) function in a sample of healthy adults. SUBJECTS/METHODS In a randomized crossover double-blind study, 65 healthy adults consumed 200 g...

The Assessment of Insulin, Glucose and Lipids in Ischemic Thrombotic Cerebrovascular Disease • Sixty-one male patients with ischemic thrombotic cerebrovascular disease (ITCVD) and 61 age-matched controls were studied to determine the interrelationships between the primary risk factors of ITCVD. Impaired carbohydrate metabolism in ITCVD was reflected in the significantly greater number of abnorm...

PURPOSE Video capsule endoscopy (VCE) is a procedure that uses a wireless camera to take pictures of the gastrointestinal (GI) tract. A wireless motility capsule (WMC) of a similar size has been developed, which measures pH, pressure, and temperature and can be used to assess regional and total GI transit times. VCE could also potentially be used as a tool for measuring small bowel transit time...

BACKGROUND Diabetes mellitus (DM) and impaired glucose tolerance (IGT) are not uncommonly associated with hypertension. Fasting blood glucose level is still recognized as an indicator of DM. METHODS We studied 99 consecutive patients who were not known to be diabetic patients and with no cardiac history, who were attending our Hypertension Clinic for investigation and management of uncontroll...

OBJECTIVE To compare perinatal outcome of women after third trimester oral glucose tolerance test (GTT) following normal glucose challenge test (GCT) stratified by test results. STUDY DESIGN Retrospective cohort study of women delivered in a tertiary, university affiliated medical center (2007-2012). Inclusion criteria were women with a normal 50 g GCT (<140 mg/dl) followed by GTT, who delive...
