1. Activity budget and social behavior of urban capuchin monkeys, Sapajus sp. (Primates: Cebidae)
ABSTRACT Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins

2. Interação entre humanos e macacos-prego Cebus libidinosus Spix, 1823 sob a influência de ambientes antropizados / Interaction betweeen humans and capuchin monkeys Cebus libidinosus Spix, 1823 and under the influence of anthropic environments
Macacos-prego são detentores de um forte poder cognitivo, o que resulta em uma alta flexibilidade comportamental. Essa característica contribui para sua adaptação aos mais diversos locais e situações. Neste estudo, procuramos testar se o repertório comportamental dos macacos-prego é modulado em função da presença de predadores/competidores, das ca

4. Comparison of dengue infection in human mononuclear leukocytes with mosquito C6/36 and mammalian Vero cells using flow cytometry to detect virus antigen
Fluorescent activated cell sorter (FACS) analysis is useful for the detection of cellular surface antigens and intracellular proteins. We used this methodology in order to detect and quantify dengue antigens in highly susceptible cells such as clone C6/36 (Aedes albopictus) and Vero cells (green monkey kidney). Additionally, we analyzed the infection in vitr

5. A second gene for the African green monkey poliovirus receptor that has no putative N-glycosylation site in the functional N-terminal immunoglobulin-like domain.
Using cDNA of the human poliovirus receptor (PVR) as a probe, two types of cDNA clones of the monkey homologs were isolated from a cDNA library prepared from an African green monkey kidney cell line. Either type of cDNA clone rendered mouse L cells permissive for poliovirus infection. Homologies of the amino acid sequences deduced from these cDNA sequences w

6. Identification and cloning of endogenous retroviral sequences present in human DNA.
Using nonstringent annealing conditions and a 2.75-kilobase segment of cloned African green monkey DNA that specifically hybridizes to the proviruses of AKR ecotropic murine leukemia virus (MuLV) and baboon endogenous virus (BaEV) as a probe, we detected related sequences in three different preparations of human brain DNA fragments. The blot-hybridization pa

7. Human and Simian Immunodeficiency Virus Capsid Proteins Are Major Viral Determinants of Early, Postentry Replication Blocks in Simian Cells
The cells of most Old World monkey species exhibit early, postentry restrictions on infection by human immunodeficiency virus type 1 (HIV-1) but not by simian immunodeficiency virus of macaques (SIVmac). Conversely, SIVmac, but not HIV-1, infection is blocked in most New World monkey cells. By using chimeric HIV-1/SIVmac viruses capable of a single round of

8. The Level of CD4 Expression Limits Infection of Primary Rhesus Monkey Macrophages by a T-Tropic Simian Immunodeficiency Virus and Macrophagetropic Human Immunodeficiency Viruses
The entry of primate immunodeficiency viruses into cells is dependent on the interaction of the viral envelope glycoproteins with receptors, CD4, and specific members of the chemokine receptor family. Although in many cases the tropism of these viruses is explained by the qualitative pattern of coreceptor expression, several instances have been observed wher

10. Identification of Amino Acid Residues in CD81 Critical for Interaction with Hepatitis C Virus Envelope Glycoprotein E2
Human CD81 has been previously identified as the putative receptor for the hepatitis C virus envelope glycoprotein E2. The large extracellular loop (LEL) of human CD81 differs in four amino acid residues from that of the African green monkey (AGM), which does not bind E2. We mutated each of the four positions in human CD81 to the corresponding AGM residues a

11. Lv1 Inhibition of Human Immunodeficiency Virus Type 1 Is Counteracted by Factors That Stimulate Synthesis or Nuclear Translocation of Viral cDNA
Human immunodeficiency virus type 1 (HIV-1) cDNA synthesis is inhibited in cells from some nonhuman primates by an activity called Lv1. Sensitivity to restriction by Lv1 maps to a region of the HIV-1 CA required for interaction with the cellular protein cyclophilin A. A similar antiviral activity in mammalian cells, Ref1, inhibits reverse transcription of mu

12. Adenovirus early region 4 34-kilodalton protein directs the nuclear localization of the early region 1B 55-kilodalton protein in primate cells.
The localization of the adenovirus type 5 34-kDa E4 and 55-kDa E1B proteins was determined in the absence of other adenovirus proteins. When expressed by transfection in human, monkey, hamster, rat, and mouse cell lines, the E1B protein was predominantly cytoplasmic and typically was excluded from the nucleus. When expressed by transfection, the E4 protein a
