Phylogeography and genetic connectivity of the marine macro-alga Sargassum ilicifolium (Phaeophyceae, Ochrophyta) in the northwestern Pacific.

The evolutionary influences of historical and contemporary factors on the population connectivity and phylogeographic structure of a brown seaweed, Sargassum ilicifolium, were elucidated using the nuclear ITS2 and mitochondrial COI markers for the collections newly sampled within its distribution range in the northwestern Pacific (NWP). Significant genetic structure at variable levels was identified between populations (pairwise F ) and among populations grouped by geographical proximity (Φ among regions). The adjacent groups of populations with moderate structure revealed from AMOVA appeared to have high genetic connectivity.

Immune reconstitution inflammatory syndrome associated with secondary syphilis.

Immune reconstitution inflammatory syndrome (IRIS) is a condition associated with paradoxical worsening and/or new onset of an opportunistic infection in HIV patients following the initiation of anti-retroviral therapy or switching to more potent antiretroviral therapy (ART) regimen. Although IRIS associated with many opportunistic infections (OIs) has been well reported, syphilis has very rarely been mentioned in this regard. A 52-year-old male, diagnosed with AIDS six weeks ago, presented with the disseminated non-pruritic painless skin rash.

Eosinophilic cytoplasmic inclusion bodies in vesicular multinucleated melanocytes: a clue to the diagnosis of benign melanocytic lesions.

Different types of multinucleated melanocytes have been described in benign and malignant melanocytic lesions. Here we describe a relatively common, though underappreciated, type of multinucleated melanocyte characterized by abundant vesicular and fibrillary-appearing cytoplasm containing one or multiple eosinophilic inclusion bodies. In our experience, these vesicular multinucleated melanocytes with inclusion bodies are invariably seen in nevi of long duration.
