Anatomic and clinical implications of venous drainage variations in superior segment resections for clinical T1N0 non-small cell lung cancer.

Background: Superior segmentectomies for clinical T1N0 non-small cell lung cancer (NSCLC) often suffer from inadequate surgical margins. Our study aimed to enhance the precision of superior segmentectomies by focusing on the anatomical features of the superior segmental vein (V) branches, and assess the relevant outcomes.

Methods: The clinical data of 646 patients with cT1N0 NSCLC who underwent video-assisted thoracic surgery (VATS) from August 2020 to August 2021 were retrospectively analyzed.

Three-dimensional reconstruction for determining positional indications of pulmonary segmentectomy/subsegmentectomy for ground glass opacity-dominant clinical T1a-bN0 non-small cell lung cancer.

Background: The precision of segmentectomy/subsegmentectomy for ground glass opacity (GGO)-dominant cT1a-bN0 non-small cell lung cancer (NSCLC), including mono-segmentectomy, mono-subsegmentectomy, combined subsegmentectomies, and single segmentectomy with adjacent subsegmentectomy, has improved. The aim of this study is to investigate their positional indications by focusing on the three-dimensional location of lesions, utilizing three-dimensional computed tomography bronchography and angiography (3D-CTBA).

Methods: We retrospectively analyzed 195 patients with GGO-dominant cT1a-bN0 NSCLC who underwent segmentectomy/subsegmentectomy between August 2015 and November 2020.

Extracellular RNA profiles in non-small cell lung cancer plasma.

Background: Non-small cell lung cancer (NSCLC) has a high mortality rate and poor prognosis. The early detection of high-risk patients is essential to improve patient prognosis. Thus, the identification of a non-invasive, non-radiative, convenient, and fast diagnostic approach should be a top priority in NSCLC research.

A novel glycosyltransferase-related lncRNA signature correlates with lung adenocarcinoma prognosis.

Background: Lung adenocarcinoma (LUAD) is one of the most fatal cancers in the world. Previous studies have shown the increase in glycosylation level, and abnormal expressions of related enzymes are closely related to various cancers. Long non-coding RNAs (lncRNAs) play an important role in the proliferation, metabolism, and migration of cancer cells, but the underlying role of glycosyltransferase (GT)-related lncRNAs in LUAD remains to be elucidated.

Partitioning the lung field based on the depth ratio in three-dimensional space.

Background: To explore the feasibility of the depth ratio method partitioning the lung parenchyma and the depth distribution of lung nodules in pulmonary segmentectomy.

Methods: Based on the measurement units, patients were allocated to the chest group, the lobar group, and the symmetrical 3 sectors group. In each unit, the center of the respective bronchial cross-section was set as the starting point (O).

[Research Status of Tumor-associated Fibroblasts Regulating Immune Cells].

Cancer-associated fibroblasts (CAFs) and tumor-infiltrating immune cells are the most essential components of the tumor microenvironment (TME). They communicate with each other in tumor microenvironment and play a critical role in tumorigenesis and development. CAFs are very heterogeneous and different subtypes of CAFs display different functions.

Low-Pt loaded on a vanadium nitride/graphitic carbon composite as an efficient electrocatalyst for the oxygen reduction reaction.

The high cost of platinum electrocatalysts for the oxygen reduction reaction (ORR) has hindered the commercialization of fuel cells. An effective support can reduce the usage of Pt and improve the reactivity of Pt through synergistic effects. Herein, the vanadium nitride/graphitic carbon (VN/GC) nanocomposites, which act as an enhanced carrier of Pt nanoparticles (NPs) towards ORR, have been synthesized for the first time.

Synergistic effect of tungsten carbide and palladium on graphene for promoted ethanol electrooxidation.

The synergistic effect of WC and Pd has large benefit for ethanol electrooxidation. The small-sized Pd nanoparticles (NPs) decorated tungsten carbide on graphene (Pd-WC/GN) will be a promising anode catalyst for the direct ethanol fuel cells. The density functional theory (DFT) calculations reveal that the strong interaction exists at the interface between Pd and WC, which induces the electron transfer from WC to Pd.

Porous graphitic carbon nanosheets derived from cornstalk biomass for advanced supercapacitors.

Porous graphitic carbon nanosheets (PGCS) are synthesized by an in situ self-generating template strategy based on the carburized effect of iron with cornstalks. Cornstalks firstly coordinate with [Fe(CN)(6)](4-) ions to form the cornstalk-[Fe(CN)(6)](4-) precursor. After carbonization and removal of the catalyst, PGCS are obtained.

In Situ intercalating expandable graphite for mesoporous carbon/graphite nanosheet composites as high-performance supercapacitor electrodes.

Mesoporous-carbon-coated graphite nanosheet (GNS@MC) composites have been synthesized by the intercalation of resol prepolymer into the interlayers of expandable graphite (EG) under vacuum-assisted conditions, followed by the exfoliation of EG through in situ polymerization, the growth of resol under hydrothermal conditions, and carbonization under Ar. The GNS@MC composites exhibit enhanced capacitive performance compared to mesoporous carbon (MC), microwaved EG after thermal treatment (T-EG), and the physical mixture of MC and T-EG (MC+T-EG). In particular, the GNS@MC-35-800 composite carbonized at 800 °C, which has a graphite-nanosheet content of 35 % and a Brunauer-Emmett-Teller surface area (S(BET) ) of 432.
