Intraoperative radiation therapy for early-stage breast cancer: a single-institution experience.

Background: To assess outcomes and toxicity after low-energy intraoperative radiotherapy (IORT) for early-stage breast cancer (ESBC).

Materials And Methods: We reviewed patients with unilateral ESBC treated with breast-conserving surgery and 50-kV IORT at our institution. Patients were prescribed 20 Gy to the surface of the spherical applicator, fitted to the surgical cavity during surgery.

Deadly Pulmonary Hypertension Cured With a Stent.

A 77-year-old woman with critical limb ischemia, venous insufficiency, and progressive pulmonary hypertension presented for evaluation. Lower extremity angiography showed a common iliac arteriovenous fistula. Closure was achieved with a covered stent placed in the artery.

Noise distracts foraging bats.

Predators frequently must detect and localize their prey in challenging environments. Noisy environments have been prevalent across the evolutionary history of predator-prey relationships, but now with increasing anthropogenic activities noise is becoming a more prominent feature of many landscapes. Here, we use the gleaning pallid bat, , to investigate the mechanism by which noise disrupts hunting behaviour.

Stereotactic Ablative Body Radiotherapy for Primary Non-Small-Cell Lung Cancer: Achieving Local Control with a Lower Biologically Effective Dose.

We conducted a retrospective study of stereotactic ablative radiotherapy (SABR) for 94 patients with non-small-cell lung cancer at our institution. The patients were treated with either 50 Gy in five treatments or 48 Gy in four treatments, corresponding to biologically effective doses (BED) of 100 Gy or 105.6 Gy, respectively.
