The goal of the present experiment was to test the predictions of Central Bottleneck and Central Capacity Sharing models. According to the Central Bottleneck model, dual task interference, as observed in the PRP paradigm, is caused by an all-or-none bottleneck in information processing. The Central Capacity Sharing model postulates that dual task interference is caused by a capacity limited pro...

We construct embedded closed minimal surfaces in the round three-sphere S(1), resembling two parallel copies of the Clifford torus, joined by m small catenoidal bridges symmetrically arranged along a square lattice of points on the torus.

Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimu...

the testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  following doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. there was gangrene of the right testis with discoloration and ne...

OBJECTIVE To evaluate the prevalence and prenatal ultrasound detection of clubfoot in Tuscany during a period of 20 years. METHODS This is a descriptive analysis on data from the Tuscan register of congenital defects, covering a 20-year period from 1992 to 2011. The Tuscan registry of congenital defects is a population-based register for the epidemiologic surveillance of congenital anomalies....

background and purpose: mortality statistics and rates show the development of a country in the world. these statistics are very important for determining the distribution of risk factors of mortality (in age and gender groups, ethnicity and so on) and they are useful for improving health and preventing from important diseases in future planning of countries in societies. materials and methods:...

The density of nitric oxide (NO)-producing neurons in the fascia dentata and Ammon's horn was assessed in 6-month-old male rats using NADPH-diaphorase (NADPH-d) histochemistry. Two separate experiments investigated whether (1) the complete absence of neonatal handling or (2) the administration of periodic prenatal stress could affect the expression and distribution of NADPH-d reactivity in the ...

The liver plays a central role in the regulation of the metabolic status, partitioning of nutrients, and expenditure of energy. To gain insight into hepatic metabolic pathways and key transcripts affecting traits related to body composition, liver expression profiles were compared of pigs of two breeds, the obese German Landrace (DL) and the lean Pietrain (Pi). Porcine oligonucleotide microarra...
