The idea of “executive function” has become a fundamental concept in contemporary neurosciences [1]. The observation that the frontal lobes are involved in regulatory behaviors, including planning, self-monitoring, problem solving, inhibiting responses, strategy development and implementation, and working memory, resulted in the comprehensive term “executive function.” Luria [2,3] first suggest...

Landfarming biodegradation is a strategy used by the petrochemical industry to reduce pollutants in petroleum-contaminated soil. We constructed 2 metagenomic libraries from landfarming soil in order to determine the pathway used for mineralization of benzene and to examine protein expression of the bacteria in these soils. The DNA of landfarm soil, collected from Ilhéus, BA, Brazil, was extract...

Alexander Romanovich Luria (1902-1977), Russian psycho logist and neuropsychologist, is recognized throughout the world as one of the most eminent and influential psychologists of the 20th century, who made advances in many areas, including cognitive psychology, the processes of learning and forgetting, mental retarda tion and neuropsychology. Luria’s scientific career was build in “the stages ...

The influence of nutrients in wastewater from dairy lagoons on the survival of Escherichia coli O157:H7 was monitored. Initially, the survival of E. coli O157:H7 in wastewater from which the competing native organisms had been removed by filter sterilization or autoclaving was compared with that in wastewater from which competing organisms had not been removed. Numbers of E. coli O157:H7 or E. ...

To examine three problems in the interpretation of the Luria-Nebraska Neuropsychological Battery (LNNB), the normal participants from four different studies were pooled to form a sample of 241 LNNB profiles. The first problem addressed was the LNNB's false positive rate. All five yes/no decision rules were applied simultaneously. Each individual rule had a 0% to 8% false positive rate: combinin...

BACKGROUND Many investigators have recognised that a significant proportion of environmental bacteria exist in a viable but non-culturable state on agar plates, and some researchers have also noticed that some of such bacteria clearly recover their growth on matrices other than agar. However, the reason why agar is unsuitable for the growth of some bacteria has not been addressed. METHODOLOGY...

Twenty-six strains of 22 bacterial species were tested for growth on trypticase soy agar (TSA) or sea-salt agar (SSA) under hypobaric, psychrophilic, and anoxic conditions applied singly or in combination. As each factor was added to multi-parameter assays, the interactive stresses decreased the numbers of strains capable of growth and, in general, reduced the vigor of the strains observed to g...

Aim of this study was to evaluate depressive symptoms in a semi-intensive Stroke Unit (SI-SU) by a scale specifically devised to assess depression in patients with stroke and to identify the symptoms better contributing to the early detection of post stroke depression (PSD). Fifty-four patients admitted to a SI-SU because of suffering from single, first-ever hemispheric stroke were enrolled. De...

Efforts to delineate the basis for variations in protein profiles of different membrane fractions from various bacterial pathogens led to the finding that even the same medium [e.g., Luria Bertani (LB) broth] purchased from different commercial sources generates remarkably dissimilar protein profiles despite similar growth characteristics. Given the pervasive roles small RNAs play in regulating...
