Background: Morbid obesity in adolescents impacts respiratory function, often leading to reduced lung volume and obstructive ventilatory defects. However, standard spirometric values frequently remain within normal ranges.
Objectives: We hypothesized that Lung Clearance Index (LCI) is a more sensitive marker for detecting airway dysfunction in adolescents with morbid obesity than conventional lung function tests.

There is limited knowledge on diffusing capacity in scoliosis patients. It remains to be determined if impaired pulmonary diffusing capacity is mostly influenced by reduced alveolar-capillary membrane diffusing capacity (D), reduced pulmonary capillary blood volume (V) or both. This study aims to report findings from dual test gas pulmonary diffusing capacity for carbon monoxide and nitric oxide (D) with quantification of pulmonary diffusing capacity for carbon monoxide corrected for haemoglobin with a five s breath-hold (D) and nitric oxide with a five s breath-hold (D), D and V.

Purpose: Fractional nasal exhaled NO (FnNO), fractional exhaled NO (FeNO) and lung function tests were performed in children with moderate-to-severe persistent allergic rhinitis (AR) to investigate the significance of the above indices in the assessment and diagnosis of children with AR.
Methods: A total of 135 children with persistent AR were selected and divided into moderate-to-severe and mild groups; serum total immunoglobulin E (IgE), peripheral blood eosinophil counts (EOS), FnNO, FeNO, and lung function tests were performed.
Results: Children in the moderate-to-severe group had increased levels of FnNO and FeNO and decreased levels of forced expiratory flow at 75% of forced vital capacity as a percentage of the predicted value (FEF75%) and maximum mid-term expiratory flow as a percentage of the predicted value (MMEF%) .

Urban air pollution has been a global challenge world-wide. While urban vegetation or forest modelling can be useful in reducing the toxicities of the atmospheric gases by their absorption, the surge in gaseous pollutants negatively affects plant growth, thereby altering photosynthetic efficiency and harvest index. The present review analyses our current understanding of the toxic and beneficial effects of atmospheric nitrogen oxides (NO), hydrogen sulphide (HS) and carbon monoxide (CO) on plant growth and metabolism.

Objective: This in vitro study aimed to analyze the effects of ionizing radiation on immortalized human osteoblast-like cells (SaOS-2) and further assess their cellular response in co-culture with fibroblasts. These analyses, conducted in both monoculture and co-culture, are based on two theoretical models of osteoradionecrosis - the theory of hypoxia and cellular necrosis and the theory of the radiation-induced fibroatrophic process.
Design: SaOS-2 cells were exposed to ionizing radiation and evaluated for cell viability, nitric oxide (NO) production, cellular morphology, wound healing, and gene expression related to the PI3K-AKT-mTOR pathway.
