A non-invasive condensation collection-ion chromatography method was established for the determination of organic acids and anions including lactic acid, formic acid, acetic acid, pyruvic acid, chloride, nitrate, nitrite, and sulfate in the exhaled breath of humans. The breath exhaled was condensed and collected using a home-made exhaled breath condensation equipment. This equipment included a disposable mouthpiece as a blow-off port, one-way valve and flow meter, cold trap, disposable condensate collection tube placed in the cold trap, and gas outlet.

Laparoscopic total adrenalectomy has become the standard treatment for adrenal mass. Meanwhile, there has been a growing trend toward laparoscopic adrenal-sparing surgery worldwide to avoid the risk and potential complications of adrenal insufficiency. The objectives of this study were to describe a retroperitoneoscopic adrenal tumor enucleation technique, to assess the clinical outcomes of this technique in the treatment of 20-40 mm nonsecreting adrenal tumor (NAT) with low potential of malignancy, and to provide a feasible choice for patients who have preference on resection.

Objective: To compare the clinical effect of "initial scheme" and "improved scheme" of acupuncture-aided anesthesia for patients undergoing thoracoscopic lobectomy.

Methods: A retrospective analysis about 2 groups ("initial scheme" and "improved scheme") of patients (40 cases in each group) who underwent thoracoscopic lobectomy was conducted in the present paper. Patients of the "initial scheme" group received thoracoscopic operation with three incisions under acupuncture-aided anesthesia i.

Tumor-associated macrophage (TAM) is regarded as an appealing cell target for cancer immunotherapy. However, it remains challenging to selectively eliminate M2-like TAM in tumor microenvironment. In this work, we employed a legumain-sensitive dual-coating nanosystem (s-T-NPs) to deliver CSF-1R inhibitor pexidartinib (PLX3397) for targeting TAM therapy.

The magnitude of the feedback between soil microbial respiration and increased mean temperature may decrease (a process called thermal adaptation) or increase over time, and accurately representing this feedback in models improves predictions of soil carbon loss rates. However, climate change entails changes not only in mean temperature but also in temperature fluctuation, and how this fluctuation regulates the thermal response of microbial respiration has never been systematically evaluated. By analysing subtropical forest soils from a 2,000 km transect across China, we showed that although a positive relationship between soil microbial biomass-specific respiration and temperature was observed under increased constant incubation temperature, an increasing temperature fluctuation had a stronger negative effect.

Article Synopsis
  • This study investigates the role of SWT1-derived circular RNAs (circSWT1) in non-small-cell lung cancer (NSCLC), finding that circSWT1 is significantly upregulated in NSCLC tissues and associated with poor patient prognosis.* -
  • Experimental methods such as qRT-PCR and various cell assays confirmed that overexpression of circSWT1 enhanced cancer cell invasion and migration by promoting epithelial-mesenchymal transition (EMT).* -
  • The mechanism revealed that circSWT1 promotes NSCLC progression by sequestering the microRNA miR-370-3p, thereby relieving its suppression of the SNAIL protein, which plays a crucial role in EMT.*

Lung cancer has been identified as one of the deadliest malignant tumors worldwide. Mounting evidence suggests that ferroptosis is a well-known non-apoptotic cell death process that participates in pathological mechanisms and is a new cancer treatment strategy. Aberrantly expressed long non-coding RNAs (lncRNAs) that drive lung cancer progression have attracted increasing attention.

Background: Previous studies have confirmed the oncogenic role of HMGB2 in various cancers, but the biological functions of HMGB2-derived circRNAs remain unknown. Thus, we intended to investigate the potential role of HMGB2-derived circRNAs in lung adenocarcinomas (LUAD) and squamous cell carcinomas (LUSC).

Methods: The expression profiles of HMGB2-derived circRNAs in LUAD and LUSC tissues and matched normal tissues were assessed using qRT-PCR.

The valve replacement is the main treatment of heart valve disease. However, thrombus formation following valve replacement has always been a major clinical drawback. Accelerating the endothelialization of cardiac valve prosthesis is the main approach to reduce thrombus.

Background: Lung cancer is one of the most lethal malignant tumors that endangers human health. Lung adenocarcinoma (LUAD) has increased dramatically in recent decades, accounting for nearly 40% of all lung cancer cases. Increasing evidence points to the importance of the competitive endogenous RNA (ceRNA) intrinsic mechanism in various human cancers.

Article Synopsis
  • CD8 T cells are important for fighting tumors, but they show dysfunction in non-small cell lung cancer (NSCLC), with unclear molecular mechanisms behind this issue.
  • The study investigates circlular ubiquitin-specific protease-7 (circUSP7), finding its levels are higher in NSCLC tissues and associated with poor patient outcomes and CD8 T cell dysfunction.
  • CircUSP7 impairs CD8 T cell activity by enhancing the expression of SHP2 and reduces the secretion of key immune molecules, potentially leading to resistance against anti-PD1 immunotherapy.

Tumour-associated macrophages (TAMs) represent an attractive cell target for anticancer therapy. However, selective and efficient targeting of TAMs remains difficult. Here, we constructed a novel dually functionalised nanoparticle platform (-T-NPs) by surface co-modification of nanoparticles (NPs) with tuftsin (T) and legumain protease-sheddable polyethylene glycol 5k (PEG) to achieve selective targeted delivery to TAMs.

Background: Transurethral seminal vesiculoscopy (TSV) is a safe and effective method for intractable hemospermia. It uses a natural cavity, is fast, involves little trauma, and boasts a low incidence of complications. Because uncontrollable penile erection during general anesthesia will severely influence the surgical operation or even damage the endoscope, spinal anesthesia was applied more on TSV.

Calcific aortic valve disease (CAVD) currently lacks a highly effective model. The presence of high concentrations of serum inorganic phosphate in patients with end-stage renal disease leads to calcification of vascular and aortic valves. Therefore, we applied inorganic phosphate to induce the osteogenic differentiation of valvular interstitial cells (VICs) and mimic its pathophysiological effects.

Paeoniflorin, an organic compound extracted from the roots of the white peony () plant, has previously been shown to exert antidepression and prokinetic effects. The traditional Chinese prescription Si-Ni-San, of which paeoniflorin is a constituent, is often used in treating depression and functional gastrointestinal disorders. The effectiveness of Si-Ni-San has been shown to be less effective in a paeoniflorin-deleted form.

In recent years, circular RNAs (circRNAs) have been increasingly reported to play a crucial role in the proliferation, migration, and invasion of non-small-cell lung cancer (NSCLC) cells. However, the circRNA MET (circMET) oncogenic mechanism that drives NSCLC development and progression remains largely unknown. In this study, the present results demonstrated that circMET expression was significantly higher in NSCLC tissues than in peritumoral tissues using quantitative real-time polymerase chain reaction.
