Epigenetics: Silent transmission

Silent Transmission of Dengue Virus

In the year 2001 a large dengue fever (DF)/dengue hemorrhagic fever (DHF) outbreak occurred in Nakhon Pathom Province, Thailand. Three thousand one hundred twelve cases of DHF were reported, an attack rate of 393 per 100,000 population. The Nakhon Pathom Provincial Health Office immediately carried out a control action according to WHO recommendations. Active serological surveys and viral RNA i...

Silent Polio Transmission: A Spatial Analysis

Silent Prions and Covert Prion Transmission

Prions are infectious agents with zoonotic potential that cause progressive neurodegenerative diseases, known as the transmissible spongiform encephalopathies (TSEs), in animals and humans. Prion disease can be initiated by a spontaneous event, handed down within families from generation to generation through genetic inheritance, or transmitted between susceptible hosts via direct exchange of b...

Immunologically silent cancer clone transmission from mother to offspring.

Rare cases of possible materno-fetal transmission of cancer have been recorded over the past 100 years but evidence for a shared cancer clone has been very limited. We provide genetic evidence for mother to offspring transmission, in utero, of a leukemic cell clone. Maternal and infant cancer clones shared the same unique BCR-ABL1 genomic fusion sequence, indicating a shared, single-cell origin...

Phosphate: the Silent Challenge

Phosphorus (P) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. It is one of the most needed nutrients for plant growth anddevelopment. Despite high levels of...
