PURPOSE To study the changes in macroprolactinomas during long-term bromocriptine therapy by means of serial MR imaging, and to correlate the findings to the serum prolactin (S-PRL) levels. PATIENTS AND METHODS Thirteen patients with macroprolactinomas were studied before and during bromocriptine therapy; six to 11 MR examinations were performed with a(More)
An MRI installation (Magnetom, Siemens, software version B1 of NUMARIS) working at 0.35 T was used to estimate T1, T2, and relative proton density in the spleen, liver, adipose tissue, and vertebral body in 14 healthy volunteers. Two double-echo sequences were applied for all subjects: TR = 500 ms, TE1 = 35 and TE2 = 70 ms; and TR = 1600 ms, TE1 = 35 and(More)
Conviction narrative theory (CNT), a social psychological approach to the way economic agents take deisions under Knightian uncertainty, together with the new methodology of directed algorithmic text analysis (DATA), provide the opportunity for a theory of economic sentiment or animal sprits grounded in empirical facts. Applying DATA to the full text of the(More)
BACKGROUND Non-contrast computed tomography (NCT) has become an important diagnostic tool in acute abdominal pain, but the drawback is the increased radiation dose compared to abdominal plain film (APF). PURPOSE To evaluate whether NCT, including low-dose computed tomography (LDCT, using 50 mAs), provides more diagnostic information than APF in patients(More)
Obtaining an accurate picture of the current state of the economy is particularly important to central banks and finance ministries, and of epidemics to health ministries. There is increasing interest in the use of search engine data to provide such 'nowcasts' of social and economic indicators. However, people may search for a phrase because they(More)
OBJECTIVE To evaluate the safety and tolerability of the T-Port(®) for intestinal infusion of levodopa/carbidopa gel in patients with advanced Parkinson's disease (PD). METHODS This prospective study was carried out in 24 patients with PD (15 males, mean age 61.8 years, mean duration PD 18.7 years). All adverse device effects were evaluated at 2 weeks, 3(More)
This article outlines efficient vector code commonly required for population based optimization methods. Specifically, techniques for population generation, probabilistic selection, recombination & mutation are introduced. These coding 'best practices' emphasize execution speed and concision over readability. As such, each snippet is initially coded in(More)
