The concept of in‐air output ratio was introduced to characterize how the incident photon
fluence per monitor unit (or unit time for a Co‐60 unit) varies with collimator settings. However, …

Purpose: As the practice of using high‐energy photon beams to create therapeutic radiation
fields of subcentimeter dimensions (as in intensity‐modulated radiotherapy or stereotactic …

Background Vascularized lymph node transfer (VLNT) has become more widespread for
surgical treatment of lymphedema. However, interaction between a transferred lymph node and …

A major challenge in stem cell differentiation is the availability of bioassays to prove cell types
generated in vitro are equivalent to cells in vivo. In the mouse, differentiation of primordial …

Patients with human papillomavirus (HPV)-positive head and neck squamous cell carcinoma
(HNSCC) have better responses to radiotherapy and higher overall survival rates than do …

Background In male pre‐pubertal cancer patients, radiation and chemotherapy impact future
fertility by eradication of spermatogonial stem cells (SSCs). In macaques, spermatogenesis …

Selective protection of the intestinal tract by EGLN inhibition enables potentially definitive
doses of radiation therapy. This might allow radiation to be a surgical surrogate for …

Background Cancer treatment of prepubertal patients impacts future fertility due to the
abolition of spermatogonial stem cells (SSCs). In macaques, spermatogenesis could be …

A key component of the Radiological Physics Center's (RPC) on‐site dosimetry review visits
are photon beam calibrations for which determination of the energy of the x rays is a key …

Hormone suppression given before or after cytotoxic treatment stimulates the recovery of
spermatogenesis from endogenous and transplanted spermatogonial stem cells ( SSC ) and …
