BACKGROUND Targeted delivery of gene therapy vectors to the mouse respiratory tract is often performed via intranasal or intratracheal administration; however, there can be a great deal of variability between these methods, which could potentially influence experimental results. Improving the accuracy and precision of lung delivery will not only reduce the number of animals required to detect s...
The main reasons for the failure of most chemopreventive agents during clinical trials are poor in vivo bioavailability and dose-limiting side effects. One potential approach to surmount these problems in lung cancer chemoprevention trials could be direct delivery of agents into the pulmonary tissue. In this study, we assessed the efficacy of intranasally delivered bio-response diindolylmethane...
Stereotactic body radiotherapy (SBRT) is a rapidly emerging technology that enhances radiation therapy delivery. It allows for tightly conformed treatment fields and accurate delivery even with moving targets in the body. SBRT currently is used most commonly in treatment of medically inoperable stage I non-small cell lung cancers, as well as lung, liver, and spinal metastases. Studies to date a...
The transition from fetus to newborn is the most complex adaptation that occurs in human experience. Lung adaptation requires coordinated clearance of fetal lung fluid, surfactant secretion, and onset of consistent breathing. The cardiovascular response requires striking changes in blood flow, pressures, and pulmonary vasodilation. Energy metabolism and thermoregulation must be quickly controll...
We present successful epidural anesthesia and assisted mechanical ventilation in a parturient woman with respiratory failure. A 41-year-old woman at 35 weeks' of gestation was entering labor. She was pneumonectomized on the left, had bronchiectasis on the remnant lung, and was under assisted mechanical ventilation by continuous positive airway pressure (CPAP) because of severely restricted lung...
BACKGROUND Infants and young children are obligate nose breathers; therefore, a transnasal route seems the logical delivery method of inhaled aerosols. The efficiency of aerosol delivery depends on several factors, such as interface, type of nebulizer, and patient age and breathing pattern. We hypothesized that the use of a vibrating mesh nebulizer, a tight-fitting face mask, and a head model a...
Antibiotic resistance is exponentially increasing, and the number of deaths caused by bacterial infections expected to surge. When dealing with respiratory system, inefficient antibiotics heighten chance death from infection. However, alternatives are limited. Bacteriophages a valid option since they can target specific type bacterium. highly avoid any side effects when delivered. their poor st...
Introduction: The purpose in this study is to analyze of DVH parameters as predictors of radiation pneumonitis and investigation on the relationship between dosimetric and clinical parameters based on PFTs as response in NTCP model and therefore achieve to lung dose- response relation in breast cancer patients. Prescribed dose to treatment volumes was 50 Gy in 2.0 Gy/fractions ...
Treatment planning based on respiration-correlated (“4D”) CT has become more common in recent years. Still, treatment delivery is typically 3D, i.e., a “one plan fits all” (motion phases) approach. 4D delivery in principle offers greater flexibility but also greater challenges, both computational and practical. We develop a computational framework to open up some of the 4D flexibility without g...
