The fluctuation characteristic of airflow is one of the important factors to influence the indoor thermal environment and human thermal comfort, which attracts researchers’ interest in these years. This paper introduces the recent researches on the fluctuation characteristics of airflow conducted in Tsinghua University. Results show that there exist obvious differences and interesting connectio...

The authors of the article published recently in the European Respiratory Journal on the prevalence and correlates of airflow obstruction in >317 000 never-smoking Chinese subjects concluded that they found inconsistent associations with exposures to household air pollution and went on to outline what future work needed to be done [1]. In the first instance, they should present table 5 having r...

OBJECTIVES/HYPOTHESIS This study examined changes in voluntary cough airflow measures immediately following in-office injection of Radiesse in patients diagnosed with glottic insufficiency. Due to significant comorbidities, these patients were poor candidates for medialization under general anesthesia. Each patient presented with dysphonia and dysphagia and ineffective voluntary cough, resultin...

The cut-off for forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) defining airflow limitation for chronic obstructive pulmonary disease (COPD) is still contested. We assessed airflow limitation prevalence by the lower limit of normal (LLN) of Global Lungs Initiative (GLI) 2012 reference values and its predictive ability for all-cause mortality and hospitalisation in very old ad...

Rhinoplasty is one of the most common and challenging cosmetic procedures. One of the complications of rhinoplasty associated with dissatisfaction is nasal obstruction, which is often due to narrowing of the nasal valve area. Application of certain procedures such as turbinoplasty can prevent and correct this problem. This study aim was to investigate the effect of inferior turbinoplasty in red...

The use of laminar airflow rooms and a life island unit for comprised patients was evaluated. Six patients spent a total of 170 days in the laminar airflow rooms and 112 days in the life island unit, and none acquired any exogenous infection. Patients were febrile for 7 out of 170 days (4.1%) in the laminar airflow rooms and 4 out of 112 days (3.6%) in the life island unit. No significant diffe...

Forty subjects, 20 women and 20 men, were exposed to airflows from five different directions: horizontally towards the front, the back, and the left side and vertically upwards and downwards. The subjects were exposed to stepwise increased air velocities ranging from less than 0.10 m/s to 0.40 m/s at three temperature levels 20, 23 and 26 o C. The results showed that airflow direction has an im...

The Drosophila mushroom body (MB) is a higher olfactory center where olfactory and other sensory information are thought to be associated. However, how MB neurons of Drosophila respond to sensory stimuli other than odor is not known. Here, we characterized the responses of MB neurons to a change in airflow, a stimulus associated with odor perception. In vivo calcium imaging from MB neurons reve...
