New olfactometric findings in Parkinson's disease.

Objectives: To investigate in Parkinson's disease-affected patients a correlation between hyposmia and gastrointestinal dysfunction and their possible identical etiopathogenesis.

Design: Retrospective cohort study.

Setting: ENT and neurology departments (Gemelli Hospital, Rome, Italy).

Discovery of the Aryl-phospho-indole IDX899, a Highly Potent Anti-HIV Non-nucleoside Reverse Transcriptase Inhibitor.

Here, we describe the design, synthesis, biological evaluation, and identification of a clinical candidate non-nucleoside reverse transcriptase inhibitors (NNRTIs) with a novel aryl-phospho-indole (APhI) scaffold. NNRTIs are recommended components of highly active antiretroviral therapy (HAART) for the treatment of HIV-1. Since a major problem associated with NNRTI treatment is the emergence of drug resistant virus, this work focused on optimization of the APhI against clinically relevant HIV-1 Y181C and K103N mutants and the Y181C/K103N double mutant.

Classification and characterization of human endogenous retroviruses; mosaic forms are common.

Background: Human endogenous retroviruses (HERVs) represent the inheritance of ancient germ-line cell infections by exogenous retroviruses and the subsequent transmission of the integrated proviruses to the descendants. ERVs have the same internal structure as exogenous retroviruses. While no replication-competent HERVs have been recognized, some retain up to three of four intact ORFs.

QTREDS: a Ruby on Rails-based platform for omics laboratories.

Background: In recent years, the experimental aspects of the laboratory activities have been growing in complexity in terms of amount and diversity of data produced, equipment used, of computer-based workflows needed to process and analyze the raw data generated. To enhance the level of quality control over the laboratory activities and efficiently handle the large amounts of data produced, a Laboratory Management Information System (LIMS) is highly-recommended. A LIMS is a complex software platform that helps researchers to have a complete knowledge of the laboratory activities at each step encouraging them to adopt good laboratory practices.
