Does surgically resected small‐cell lung cancer without lymph node involvement benefit from prophylactic cranial irradiation?

Thoracic Cancer, 2020
Background It has previously been demonstrated that surgically resected small‐cell lung cancer (SCLC) patients could benefit from prophylactic cranial irradiation (PCI). However, PCI in patients without lymph node involvement remains controversial.

Associations between comorbidities and annual incidence plus frequency of asthma exacerbation hospitalisation during the past year: data from CARN study

BMC Pulmonary Medicine, 2022
Purpose While asthma comorbidities are associated with higher health care utilisation, lower quality of life and poorer asthma control, the impact of asthma comorbidities on hospitalisation for asthma exacerbation (H-AX) remains less recognised.

Novel compound heterozygous mutations of DNAH5 identified in a pediatric patient with Kartagener syndrome: case report and literature review

BMC Pulmonary Medicine, 2021
Background Kartagener syndrome is a subtype of primary ciliary dyskinesia that may exhibit various symptoms including neonatal respiratory distress and frequent infections of the lung, sinus and middle ear because of the impaired function of motile cilia.

Carbon Isotope Fractionation in Plant Respiration

, 2020
Carbon isotopes have long been used to dissect metabolic pathways. More recently, stable isotopes have become an important tool in modeling global fluxes in the biosphere, and notably CO2 isofluxes.

Respiration in the mesopelagic and bathypelagic zones of the oceans [PDF]

, 2005
This chapter reviews the mechanisms of transport and remineralization of organic matter in the dark water-columns and sediments of the oceans. Different approaches to estimating respiration rates are compared, and the discrepancies obtained by different ...

Comparison of different objective functions for parameterization of simple respiration models [PDF]

, 2008
The eddy covariance measurements of carbon dioxide fluxes collected around the world offer a rich source for detailed data analysis. Simple, aggregated models are attractive tools for gap filling, budget calculation, and upscaling in space and time.

Characteristics of stem respiration in black spruce (Picea mariana) stand, interior Alaska

, 2021
Boreal forests account for roughly one third of the carbon sequestered in terrestrial ecosystems, and the high-latitude boreal ecosystem they make up has been consequently vulnerable to recent climate change.

Upregulation of MUC5AC by VEGF in human primary bronchial epithelial cells: implications for asthma

Respiratory Research, 2019
Background Airway mucus hypersecretion is an important pathophysiological feature in asthma. Mucins are glycoproteins that are mainly responsible for the viscoelastic property of mucus, and MUC5AC is a major mucin glycoprotein that is overproduced in ...

Plant species richness regulates soil respiration through changes in productivity [PDF]

, 2010
Soil respiration is an important pathway of the C cycle. However, it is still poorly understood how changes in plant community diversity can affect this ecosystem process.
