Effect of Laser Posterior Nasal Neurolysis for the Treatment of Chronic Rhinitis: A Randomized Controlled Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background To determine the safety and efficacy of laser ablation of the posterior nasal nerve (PNN) for the treatment of chronic rhinitis. Methods This study was a single‐center, prospective, single‐blinded, randomized sham‐controlled trial. Patients with a 24‐h reflective Total Nasal Symptom Score (rTNSS) ≧ 5, rhinorrhea ≧ 2, and congestion ≧

An open-label, one-arm, dose-escalation study to evaluate safety and tolerability of extremely low frequency magnetic fields in acute ischemic stroke [PDF]

, 2017
Extremely low frequency magnetic fields (ELF-MF) could be an alternative neuroprotective approach for ischemic stroke because preclinical studies have demonstrated their effects on the mechanisms underlying ischemic damage. The purpose of this open-label,

Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

The miR‐126‐5p and miR‐212‐3p in the extracellular vesicles activate monocytes in the early stage of radiation‐induced vascular inflammation implicated in atherosclerosis

Journal of Extracellular Vesicles, 2023
People exposed to radiation in cancer therapy and nuclear accidents are at increased risk of cardiovascular outcomes in long‐term survivors. Extracellular vesicles (EVs) are involved in radiation‐induced endothelial dysfunction, but their role in the ...
