When managing patients with acute respiratory distress syndrome (ARDS), respiratory system compliance is usually considered first and changes in resistance, although recognized, are neglected. Resistance can change considerably between minimum and maximum lung volume, but is generally assumed to be constant in the tidal volume range (V(T)). We measured resistance during tidal ventilation in 16 ...

There are no specific therapies approved by the U.S. FDA for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 COVID-19. Several agents are under clinical trial and the use of pharmacological agents are based on in vitro activity against SARS-CoV-2 or related viruses. While the efficacy of drug therapy is yet to be established, we need ...

The widespread respiratory transmission of the Covid-19 virus has taught us importance face masks to mitigate both community spread and protection wearers by masks. As such, there could be an extremely adverse public health possibility where pathogenic agents as a means bioterrorism. While eventually vaccines wide infection, protective are important way immediately prevent infections from vario...

background: the airway surfaces are one of the most common ways of entry of infectious agents. oral cavity associated lymphoid tissues are inductive site of humoral immune responses in inflammatory and infectious disorders of the upper respiratory tract. these lymphoid tissues play important roles in the induction of salivary iga. the impact of upper respiratory tract diseases on salivary iga p...

Although the global importance of RSV as a respiratory pathogen has been recognized for over 40 years, suitable prophylactic and therapeutic interventions have not been truly available. Vaccine development, unfortunately, has been fraught with spectacular failure and with difficult obstacles, and there are only limited therapeutic options for treatment of this disease. Currently, the only appro...

background: hairdressers are occupationally exposed to a number of agents in their workplace that result in respiratory symptoms and changes in pulmonary function. objective: to evaluate associations between occupational exposure and respiratory function and reported symptoms in a group of hairdressers compared to a control group. methods: a questionnaire on respiratory symptoms and workplace c...

Among the blistering (vesicant) chemical warfare agents (CWA), sulfur mustard is the most important since it is known as the “King of chemical warfare agents”. The use of sulfur mustard has caused serious damages in several organs, especially the eyes, skin, respiratory, central and peripheral nervous systems after short and long term exposure, incapacitating and even killing people and troops....
