1. América Latina a inicios de la segunda década del siglo XXI: entre el regionalismo estratégico y la regionalización fragmentada
The article analyzes the evolution of regionalism in Latin America from the 1990s. It exhibits the options that consider to the countries in their foreign policies against the initiatives of the United States and the changes in the international system. One sets out the functional importance of the emergent powers (PEMS) and the regions in the present phase

2. Detection and molecular characterization of gene 3 and 5 of turkey coronavirus (TCoV) from turkeys with severe enteritis in Brazil. / Detecção e caracterização molecular do gene 3 e 5 do coronavírus de perus (TCOV) isolados de perus com severa enterite no Brasil.
Turkey coronavirus (TCoV) is causative agent associated to Poult Enteritis and Mortality Syndrome (PEMS) in turkeys wideworld. The disease is characterized by an acute highly contagious enteric disease of turkeys characterized by depression, anorexia, diarrhea and high mortality in co mMercial turkey flocks. The presence of turkey coronavirus (TCoV) in 29 in

3. Embriogênse somática em Araucaria angustifolia (Bertol.) Kuntze, Pinus sylvestris (Linneaus) e Picea abies (Linneaus) Karsten : ontogênese, padrão de expressão proteica e do gene serk
O estudo dos mecanismos do desenvolvimento embrionário em plantas pode ser facilitado pelo estabelecimento de sistemas modelos associados a embriogênese in vitro. Avanços no conhecimento básico e aplicações biotecnológicas são decorrentes dos estudos destes sistemas biológicos. Com a finalidade de regular eficientemente a regeneração de plantas po

4. Detecção do TAstV-2 (Turkey astrovirus type 2) em perus (Meleagris gallopavo)
The reverse transcription polymerase chain reaction (RT-PCR) of turkey astrovirus (TAstV) capsid and polymerase gene was applied in the bursa of Fabricius (BF), thymus (TH), spleen (SP) and cloacal swabs (CS) from young poults with PEMS (Poult Enteritis Mortality Syndrome). The histological lesions were atrophy, lymphoid depletion, cellular infiltration and

6. Calcium-Mediated Signaling during Sandalwood Somatic Embryogenesis. Role for Exogenous Calcium as Second Messenger1
The possible involvement of Ca2+-mediated signaling in the induction/regulation of somatic embryogenesis from pro-embryogenic cells of sandalwood (Santalum album) has been investigated. 45Ca2+-uptake studies and fura-2 fluorescence ratio photometry were used to measure changes in [Ca2+]cyt of pro-embryogenic cells in response to culture conditions conducive

7. Malaria parasite exit from the host erythrocyte: A two-step process requiring extraerythrocytic proteolysis
Intraerythrocytic malaria parasites replicate by the process of schizogeny, during which time they copy their genetic material and package it into infective merozoites. These merozoites must then exit the host cell to invade new erythrocytes. To better characterize the events of merozoite escape, erythrocytes containing Plasmodium falciparum schizonts w

8. Endogenous Nod-Factor-Like Signal Molecules Promote Early Somatic Embryo Development in Norway Spruce1
Embryogenic cultures of Norway spruce (Picea abies) are composed of pro-embryogenic masses (PEMs) and somatic embryos of various developmental stages. Auxin is important for PEM formation and proliferation. In this report we show that depletion of auxin blocks PEM development and causes large-scale cell death. Extracts of the media conditioned by embryogenic

9. A protein energy malnutrition scale (PEMS).
Most assessments of protein energy malnutrition have relied on clinical impressions, laboratory tests, or anthropometric measurements. There has been a split in the field between those who favor clinical versus laboratory approaches, and each alone misclassifies about 20% of the patients. A 23-item scale is described that provides four subscores derived from
