Tumor-to-tumor metastasis is a rare phenomenon, but it has been suggested to be more frequent in patients with hereditary cancer syndrome. We report an autopsy case of tumor-to-tumor metastasis in a 75-year-old male. At 6 months before his death, the patient complained of hoarseness and dysphagia, and clinical whole-body examinations revealed advanced lung adenocarcinoma (T4N2M1b, Stage IV), mu...

Long-distance dispersal (LDD) of seeds and pollen shapes the spatial dynamics of plant genotypes, populations and communities. Quantifying LDD is thus important for predicting the future dynamics of plants exposed to environmental changes. However, environmental changes can also alter the behaviour of LDD vectors: for instance, increasing air temperature may enhance atmospheric instability, the...

Anisotropic (direction-dependent) long-distance dispersal (LDD) by wind has been invoked to explain the strong floristic affinities shared among landmasses in the Southern Hemisphere. Its contribution has not yet been systematically tested because of the previous lack of global data on winds. We used global winds coverage from the National Aeronautics and Space Administration SeaWinds scatterom...

OBJECTIVE To assess whether the Movement ABC can be used to monitor individual change in motor performance. DESIGN Motor-impaired children were tested three times in succession with the Movement ABC without any intervention. SETTING Two schools for special education and one school for children who are chronically ill. SUBJECTS Three girls and 20 boys aged 6-8 years. MAIN OUTCOME MEASURE...

A 2-year-old boy presented with delayed motor skills and language since birth. Family history disclosed consanguineous parents. Examination showed global muscular hypotonia, optic atrophy, oculomotor apraxia, and normal head circumference. Brain MRI showed optic atrophy and macrocerebellum (figure). Laboratory tests revealed deficient activity of a-L-iduronidase in peripheral blood leukocytes a...
