Fueled by the promise of regenerative medicine, currently there is unprecedented interest in stem cells. Furthermore, there have been revolutionary, but somewhat controversial, advances in our understanding of stem cell biology. Stem cells likely play key roles in the repair of diverse lung injuries. However, due to very low rates of cellular proliferation in vivo in the normal steady state, ce...

human airway is generally destructed by inhaled factors and is the barrier to the external environment and has a crucial role in protection of the internal homeostasis of the lung. sulfur mustard (sm) is a chemical warfare that capable of producing severe chemical injuries primarily in the lungs. trefoil factor family (tffs) plays major roles in epithelial repair and homeostasis, particularly i...

'\J Out of 43 ruptures of the spleen 14, or 32*5 per cent, were accompanied by injuries of other orgaus, during the 9 years I have been considering. Of these, 5 or 35'7 per cent., were complicated with ruptures of the liver; 3, or 21*4 per cent., with those of the left kidney; 1, or 7*1 per cent., with laceration of the brain ; 1, or 7*1 percent., of the stomach ; 1, or 7*1 percent., with lacer...

Due to the rapid development of the nanotechnology industry in the last decade, nanoparticles (NPs) are omnipresent in our everyday life today. Many nanomaterials have been engineered for medical purposes. These purposes include therapy for pulmonary diseases. On other hand, people are endeavoring to develop nanomaterials for improvement or replacement of traditional therapies. On the other han...

The lung tissue, exposed to x-rays of sufficient intensity, eventually show signs, like other tissues, of damage, recognizable by inflammation and subsequently by scarring. Such damage has been known since 1922 and a number of papers testify to the clinical and pathological findings associated with irradiation. Engeistad and Warren and Spencer confirm these findings in histological and experime...

Thoracic trauma can involve serious injuries of both the rib cage and thoracic organs. The leading cause of thoracic trauma is motor vehicle crashes (MVCs). Rib fractures are often associated with injuries to the underlying organs. This paper investigates the situations in which lung, liver, and spleen injuries occur with associated rib fractures. Side impacts were found to have corresponding o...

Impalement rectal injuries with intraperitoneal organ injuries are rare. It is even rarer for such injuries to result in pelvic, abdominal and thoracic internal injuries. We present the case of a 39-year-old man who was admitted after an assault where a broken broomstick was inserted forcibly into his rectum. Surgery revealed penetration through the rectum, dome of the bladder, mesentery, live...

CONTEXT Premature infant lung development may be affected by lung injuries during the first few weeks of life. Lung injuries have been associated with changes in lung mechanics. OBJECTIVE To evaluate an association between lung mechanics and lung structural alterations in very low birth weight infants (birth weight less than 1500 g). DESIGN A cross-sectional evaluation of pulmonary mechanic...

bronchiolitis has been known as one of the pathological features of lung injuries in mustard gas exposed patients the purpose of this research was to evaluate the efficacy of interferon gamma-1b on the lung function in mustard gas exposed patients with bronchiolitis. in multicenter research interferon gamma-1b was effective in pulmonary fibrosis with unknown reason, but assessment of effect of ...

one of the main components of lung alveoli is surfactant. dppc (dipalmitolphosphatidylcholine) is thepredominant lipid component in lung surfactant that is responsible for lowering surface tension in alveoli in thisarticle. we used a very approximate model with computational method of ab initio to describe the interactionsbetween dppc as important component of lung surfactant and some chemical ...
