Deep imaging of β Pictoris at L’: asymmetries in the disc and constraints on planets

We demonstrate here the potential of VLT/NaCo at L’ (3.8μm) in Angular Differential Imaging (ADI). We detect the β Pictoris disc above 5σ between 0.4’’ and 3.8’’, after combining data from 7 epochs or 3.1 years. To avoid the smearing of the planet due to its orbital motion within this time span (green arrow), we subtracted the planet from the 7 datasets. We used a star subtraction technique based on PCA (Soummer et al. 2012) and corrected for ADI biases by iterating. We implemented a forward modeling approach to constrain the dust distribution

Semen-Derived Amyloid Fibrils Drastically Enhance HIV Infection

SummarySexual intercourse is the major route of HIV transmission. To identify endogenous factors that affect the efficiency of sexual viral transmission, we screened a complex peptide/protein library derived from human semen. We show that naturally occurring fragments of the abundant semen marker prostatic acidic phosphatase (PAP) form amyloid fibrils. These fibrils, termed Semen-derived Enhancer of Virus Infection (SEVI), capture HIV virions and promote their attachment to target cells, thereby enhancing the infectious virus titer by several orders of magnitude. Physiological concentrations of SEVI amplified HIV infection of T cells, macrophages, ex vivo human tonsillar tissues, and transgenic rats in vivo, as well as trans-HIV infection of T cells by dendritic or epithelial cells. Amyloidogenic PAP fragments are abundant in seminal fluid and boost semen-mediated enhancement of HIV infection. Thus, they may play an important role in sexual transmission of HIV and could represent new targets for its prevention
