Why All This Fuss Over Sex?

The mating of the two sexes, or sexual intercourse,- to achieve reproduction is a natural phenomenon. Because of the overemphasis on the problem of sexual adjustment of marriage, some have advocated pre-marital sexual relations in an attempt to determine if a couple is suited for matrimony. This is a grave error. There is no necessity for pre-marital sexual practice or attempts of practice

Anthropogenic noise is associated with changes in acoustic but not visual signals in red-winged blackbirds

Some birds in noisy areas produce songs with higher frequency and/or amplitude and altered timing compared to individuals in quiet areas. These changes may function to increase the efficacy of acoustic signals by reducing masking by noise. We collected audio recordings of red-winged blackbirds and measured noise levels. We found that males in noisier places produced songs with fewer syllables and slower repeat rate of elements in some components (rattles). Birds may also improve the efficacy of communication in noise by increasing usage of other signaling modalities. Red-winged blackbirds also perform a visual display in different intensities while singing. We also tested whether this species performs the visual display in different intensities according to current noise levels, and predicted that if the efficacy of songs is impaired in noisy places, males would compensate by performing a more intense visual display. For this, we also collected visual recordings from the same males from which we obtained acoustic recordings. We found no association between acoustic noise and the intensity of the visual display; thus, our results do not support the idea that males are using the visual display as a backup signal to communicate under acoustic noise. We discuss some possible explanations of this negative finding and for the observed noise-related changes in song length and rattle rate in the context of communication under noise

Geographic Heterogeneity of 4 Common Worldwide Cystic Fibrosis Non-DF508 Mutations in Brazil

Cystic fibrosis (CF) is an autosomal recessive disease caused by at least 750 different mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The frequency of the most common mutation (DF508) in Brazilian patients of European origin is 47%. To determine the frequency of 4 other common CF mutations (G542X, G551D, R553X, and N1303K) in Brazilian patients of European origin, we used direct polymerase chain reaction (PCR) amplification of DNA obtained from dried blood spots on Guthrie cards. The DNA came from 247 non-DF508 chromosomes from 172 Brazilian CF patients ascertained from 5 different states of Brazil. The results show that the 4 mutations account for 17% of the non-DF508 alleles and only 9% of the total number of Brazilian CF alleles. Overall, the frequency of each mutation is different from northern European and North American populations but similar to southern European populations, mainly the Italian and Spanish populations. When Brazilian patients of European origin are grouped according to state of birth, the frequencies of the mutations are significantly different between southern and southeastern states of Brazil. Therefore there are serious implications for risk assessment of DNAbased tests in heterogeneous populations such as Brazilians. Further studies are needed to identify the remaining 44% of CF mutations for the different populations and regions of Brazil

Molecular Epidemiology of Simian Immunodeficiency Virus SIVsm in U.S. Primate Centers Unravels the Origin of SIVmac and SIVstm

Retrospective molecular epidemiology was performed on samples from four sooty mangabey (SM) colonies in the United States to characterize simian immunodeficiency virus SIVsm diversity in SMs and to trace virus circulation among different primate centers (PCs) over the past 30 years. The following SIVsm sequences were collected from different monkeys: 55 SIVsm isolates from the Tulane PC sampled between 1984 and 2004, 10 SIVsm isolates from the Yerkes PC sampled in 2002, 7 SIVsm isolates from the New Iberia PC sampled between 1979 and 1986, and 8 SIVsm isolates from the California PC sampled between 1975 and 1977. PCR and sequencing were done to characterize the gag, pol, and env gp36 genes. Phylogenetic analyses were correlated with the epidemiological data. Our analysis identified nine different divergent phylogenetic lineages that cocirculated in these four SM colonies in the Unites States in the past 30 years. Lineages 1 to 5 have been identified previously. Two of the newly identified SIVsm lineages found in SMs are ancestral to SIVmac251/SIVmac239/SIVmne and SIVstm. We further identified the origin of these two macaque viruses in SMs from the California National Primate Research Center. The diversity of SIVsm isolates in PCs in the United States mirrors that of human immunodeficiency virus type 1 (HIV-1) group M subtypes and offers a model for the molecular epidemiology of HIV and a new approach to vaccine testing. The cocirculation of divergent SIVsm strains in PCs resulted in founder effects, superinfections, and recombinations. This large array of SIVsm strains showing the same magnitude of diversity as HIV-1 group M subtypes should be extremely useful for modeling the efficacy of vaccination strategies under the real-world conditions of HIV-1 diversity. The genetic variability of SIVsm strains among PCs may influence the diagnosis and monitoring of SIVsm infection and, consequently, may bias the results of pathogenesis studies
