Mutations in several mitochondrial DNA and nuclear genes involved in mitochondrial protein synthesis have recently been reported in combined respiratory chain deficiency, indicating a generalized defect in mitochondrial translation. However, the number of patients with pathogenic mutations is small, implying that nuclear defects of mitochondrial translation are either underdiagnosed or intraute...

Mitochondrial number and function are altered in response to external stimuli in eukaryotes. While several transcription/replication factors directly regulate mitochondrial genes, the coordination of these factors into a program responsive to the environment is not understood. We show here that PGC-1, a cold-inducible coactivator of nuclear receptors, stimulates mitochondrial biogenesis and res...
Recursive Bayesian estimation of respiratory motion using a modified autoregressive transition model
Compensation for respiratory motion has been identified as a crucial factor in achieving high resolution Nuclear Medicine (NM) imaging. Many motion correction approaches have been studied and they are seen to have advantages over simpler approaches such as respiratory gating. However, all motion correction approaches rely on an assumption or estimation of respiratory motion. This paper builds u...
Background and aims: Employees in hospitals and healthcare centers are exposed to a wide range of respiratory contaminants, such as biological and chemical contaminants. To protect employees against these hazards, it is necessary to use respiratory masks with appropriate protection factor. This study aimed to assess respiratory hazards risk to determine the protection factor of mask in one of t...
