A hundred-year-old insight into the gut microbiome!

As the National Institutes of Health-funded Human Microbiome Project enters its second phase, and as a major part of this project focuses on the human gut microbiome and its effects on human health, it might help us to travel a century back in time and examine how microbiologists dealt with microbiome-related challenges similar to those of the 21st century using the tools of their time.

man-to-human transmission occurred is a scientifi c judgment. We agree with Uyeki and Bresee that statistical modeling can provide useful and supportive insights, and we hope that epidemiologic teams who investigate and control potential infectious disease outbreaks will carry the TranStat software (2) into the fi eld with them. We are grateful that Uyeki and Bresee point out that immediate imp...

Mitophagy: New Insight into the Cardiovascular Aging  

Four hundred-million-year-old vesicular arbuscular mycorrhizae.

The discovery of arbuscules in Aglaophyton major, an Early Devonian land plant, provides unequivocal evidence that mycorrhizae were established >400 million years ago. Nonseptate hyphac and arbuscules occur in a specialized meristematic region of the cortex that continually provided new cells for fungal infection. Arbuscules are morphologically identical to those of living arbuscular mycorrhiza...

Isolated cutaneous sarcoidosis: a new insight into the old entity.

Cutaneous lesions are a part of common manifestation in multi-systemic sarcoidosis and skin involvement occurs in 20% to 35% of the patients with systemic disease. An exclusive cutaneous involvement is rare and it is reported in about 4%-5% of the patients of sarcoidosis. These lesions have been classified into specific and non-specific, depending on the presence of non- caseating granulomas, o...
