The eff ectiveness of youth access laws is still disputed, however, as are the costs of public smoking bans to the hospitality industry. Using a unique data set on cigarette sales at more than 100k vending machines that provides fi rst objective evidence on the ...

Loricariidae (Siluriformes, Hypostominae) is one of the most diverse catfish families. In spite of the wide distribution of loricariids in South America, cytogenetic reports are available for only a few species, mostly from southern and southeastern Brazil. We made the first chromosomal analysis of Hypostomus aff. unae from the Contas River basin in northeastern Brazil. Four populations is...

Th e infl uence of partial defoliation performed at diff erent grapevine growth stages on yield components, vegetative growth and fruit composition of ‘Istrian Malvasia’ (‘Malvazija istarska’) vines was investigated. During two consecutive seasons partial defoliation was performed manually at three grapevine growth stages; before bloom (BB), aft er bloom (AB), and at the beginning of bunch clos...

BACKGROUND In chronic schizophrenia and chronic bipolar disorder, gamma band (30-100 Hz) auditory steady-state electroencephalogram responses (ASSRs) are reduced in power and phase locking, likely reflecting neural circuit dysfunction. Here we examined whether gamma ASSR deficits are also present at first hospitalization for psychosis. METHODS Subjects were 16 first episode schizophrenia pati...

Mycobacterium intracellulare Mino grows progressively in the organs of C57BL/6 mice. When C57BL/6 mice were injected with strain Mino, very weak or almost no delayed-type hypersensitivity (DTH) to the specific antigen, M. intracellulare purified protein derivative, was observed. The DTH response was enhanced by cyclophosphamide pretreatment, indicating that some suppression mechanism(s) might b...
