1. O CONTRASTE ENCOBERTO DE VOZEAMENTO EM UM CASO DE DESVIO FONOLÓGICO
Neste trabalho, investiga-se a existência do contraste encoberto de vozeamento nas plosivas não-vozeadas [p], [t], [k], e vozeadas [b], [d], [g] do Português brasileiro, na fala de um sujeito com desvio fonológico. As plosivas foram os segmentos selecionados como alvo desta investigação após análise de oitiva das produções de fala espontânea da in

2. Aquisição dos roticos em crianças com queixa fonoaudiologica / The acquisition of rhotic sounds in children with so called deviant phonological systems
O objetivo deste estudo foi investigar o processo de aquisição dos róticos por crianças com queixa fonoaudiológica relacionada ao sistema fônico. Foram coletados dados de fala de dois sujeitos com dificuldades de pronúncia de sons róticos. O quadro de referência teórico adotado na análise foi a Fonologia Gestual (Fonologia Articulatória FAR propo

3. Syndromes of transient amnesia: towards a classification. A study of 153 cases.
Of 153 patients presenting with acute transient amnesia, 114 fulfilled the proposed strict diagnostic criteria for transient global amnesia (TGA). The prognosis of this group was excellent with the exception of a small subgroup (7%), largely identifiable because of atypically brief or recurrent attacks, who developed epilepsy of temporal lobe type on follow

4. Viral Ribonucleic Acid Synthesis by Newcastle Disease Virus Mutants Isolated from Persistently Infected L Cells: Effect of Interferon
The synthesis of different viral ribonucleic acid (RNA) species was studied in chick embryo (CE) and mouse L-cell cultures infected with the Herts strain of Newcastle disease virus (NDVo) and a mutant isolated from persistently infected L cells (NDVpi). In CE cell cultures, both viruses synthesized significant amounts of 54, 36, and 18S RNA. However, in L ce

5. Topographical rearrangements of visna virus envelope glycoprotein during antigenic drift.
Visna virus undergoes antigenic drift during persistent infection in sheep and thus eludes neutralizing antibodies directed against its major envelope glycoprotein, gp135. Antigenic variants contain point mutations in the 3' end of the genome, presumably within the envelope glycoprotein gene. To localize the changes in the viral proteins of antigenic mutants

6. Cells Persistently Infected with Newcastle Disease Virus: II. Ribonucleic Acid and Protein Synthesis in Cells Infected with Mutants Isolated from Persistently Infected L Cells
A comparison of the replication patterns in L cells and in chick embryo (CE) cell cultures was carried out with the Herts strain of Newcastle disease virus (NDVo) and with a mutant (NDVpi) isolated from persistently infected L cells. A significant amount of virus progeny, 11 plaque-forming units (PFU)/cell, was synthesized in L cells infected with NDVo, but
