Mitochondrial Quality Control: A New Perspective in Skeletal Muscle Dysfunction of Chronic Obstructive Pulmonary Disease.

Skeletal muscle dysfunction (SMD), one of the extrapulmonary complications in patients with chronic obstructive pulmonary disease (COPD), considerably influences patient prognosis. Mitochondria regulates their dynamic networks through a mitochondria quality control (MQC) mechanism, involving mitochondrial biogenesis, mitochondrial dynamics, and mitophagy. The MQC is crucial for mitochondrial homeostasis and health, and disruption of it can lead to mitochondrial damage, which is a key factor in the structural and functional impairment of skeletal muscle in COPD.

Safety and efficacy of anatomical tunneling technique for precise lung segment resection in complex anatomical settings.

Background: Thoracoscopic segmentectomy is the main surgical method for the treatment of earlylung cancer. With the promotion of technology and increasingly accurate criteria for lung subsegments, lung nodules with complex positions involving intersegmental and multisegments have become technical bottlenecks. This study aimed to verify whether seeking anatomical conditions for creating a fissure by tunneling techniques with precise resection of lung segments could solve this bottleneck problem.

Oncologic outcomes of three-dimensional navigation-guided segmentectomy for early-stage non-small cell lung cancer >2-3 cm.

Background: The outcomes of segmentectomy for small (≤2 cm) non-small cell lung cancer (NSCLC) have been well demonstrated. This study aimed to investigate whether segmentectomy could achieve comparable oncologic outcomes with lobectomy for >2-3 cm lung cancer.

Methods: Patients who underwent segmentectomy or lobectomy for NSCLC >2-3 cm were retrospectively screened.

[Progress of experimental research on the underlying mechanisms of acupuncture in improving chronic obstructive pulmonary disease].

Chronic obstructive pulmonary disease (COPD) is a common disease that seriously jeopardizes human health and affects patients' quality of life. The clinical efficacy of acupuncture in treating COPD is definite, and it can exert positive effects such as improving skeletal muscle degradation, airway mucus hypersecretion and pulmonary vascular remodeling in COPD rats. In recent years, the research on the underlying mechanisms of acupuncture in improving COPD has become more and more in-depth.

Superhydrophobic nanocellulose-based self-assembled flexible SERS substrates for pesticide detection.

Flexible surface-enhanced Raman scattering (SERS) substrates that provide simple sampling are helpful for the on-site detection of explosive contamination, pesticide residues on food surfaces, and water pollution in public spaces. Using superhydrophobic nanocellulose-based film as the support, 2D flexible SERS substrates that integrated sampling, enrichment, and detection were successfully fabricated via the solvent-induced evaporation method. This approach enabled the co-loading of two plasmonic nanoparticles with different sizes and shapes.

Exercise Attenuate Diaphragm Atrophy in COPD Mice via Inhibiting the RhoA/ROCK Signaling.

Background: Exercise is an indispensable component of pulmonary rehabilitation with strong anti-inflammatory effects. However, the mechanisms by which exercise prevents diaphragmatic atrophy in COPD (chronic obstructive pulmonary disease) remain unclear.

Methods: Forty male C57BL/6 mice were assigned to the control (n=16) and smoke (n=24) groups.

Aerobic exercise training engages the canonical wnt pathway to improve pulmonary function and inflammation in COPD.

Background: We studied whether the exercise improves cigarette smoke (CS) induced chronic obstructive pulmonary disease (COPD) in mice through inhibition of inflammation mediated by Wnt/β-catenin-peroxisome proliferator-activated receptor (PPAR) γ signaling.

Methods: Firstly, we observed the effect of exercise on pulmonary inflammation, lung function, and Wnt/β-catenin-PPARγ. A total of 30 male C57BL/6J mice were divided into the control group (CG), smoke group (SG), low-intensity exercise group (LEG), moderate-intensity exercise group (MEG), and high-intensity exercise group (HEG).

Revisiting airway epithelial dysfunction and mechanisms in chronic obstructive pulmonary disease: the role of mitochondrial damage.

Chronic exposure to environmental hazards causes airway epithelial dysfunction, primarily impaired physical barriers, immune dysfunction, and repair or regeneration. Impairment of airway epithelial function subsequently leads to exaggerated airway inflammation and remodeling, the main features of chronic obstructive pulmonary disease (COPD). Mitochondrial damage has been identified as one of the mechanisms of airway abnormalities in COPD, which is closely related to airway inflammation and airflow limitation.

[Impact of the Size and Depth of Pulmonary Nodules on the Surgical Approach for Lung Resection in the Treatment of Early-stage Lung Cancer ≤2 cm].

Background: Current studies suggest that for early-stage lung cancers with a component of ground-glass opacity measuring ≤2 cm, sublobar resection is suitable if it ensures adequate margins. However, lobectomy may be necessary for some cases to achieve this. The aim of this study was to explore the impact of size and depth on surgical techniques for wedge resection, segmentectomy, and lobectomy in early-stage lung cancer ≤2 cm, and to determine methods for ensuring a safe resection margin during sublobar resections.

Fluorescent Eu-MOF@nanocellulose-based nanopaper for rapid and sensitive detection of uranium (Ⅵ).

Radioactive uranium leaks into natural water bodies mainly in the form of uranyl ions (UO), posing ecological and human health risks. Fluorescent europium-based metal-organic frameworks (Eu-MOFs) have been demonstrated to be effective fluorescent sensors for UO, but the large size, powder state and poor dispersity limit their further application. In this work, fluorescent Eu-MOFs were in-situ grown on TEMPO-oxidized cellulose nanofibers (TOCNFs), which is the first time that spherical Eu-MOF crystals with sizes below 10 nm were prepared.

Fluorescent bacterial cellulose@Zr-MOF via in-situ synthesis for efficient enrichment and sensitive detection of Cr(VI).

In this study, for the first time, a new Zr-metal-organic framework (MOF) with strong aggregation-induced emission was successfully grown on bacterial cellulose (BC) using an in situ synthesis method, yielding the fluorescent composite nanofiber BC@Zr-MOF. The BC with abundant hydroxyl groups, which can be uniformly wrapped in the interior of the MOF layer to form BC@Zr-MOF, was used as the growth template. The resulting composite nanofibers had a higher specific surface area (1, 116 m/g), stronger fluorescence emission and better pH stability than MOF particles.
