High-Efficiency Silane Utilization in Amine-Modified Adsorbents for Direct Air Capture through Interconnected Three-Dimensional Pores.

Economic synthesis of amine-modified solid adsorbents is pivotal for the global-scale direct air capture (DAC) technologies required to realize net-zero emissions. To address the problems of the traditional reflux method using excessively costly amino silane, we propose introducing silane by impregnation into mesoporous silica with interconnected three-dimensional pores. X-ray diffraction, Fourier transform infrared spectroscopy, N adsorption-desorption, transmission electron and scanning electron microscopies, magic-angle spinning nuclear magnetic resonance, and elemental analysis identified the spatial distribution of amino silane in the materials with different loading levels.

Textured Potassium Sodium Niobate Lead-Free Ceramics with High and for Meeting High-Power Applications.

Potassium sodium niobate (KNN) lead-free piezoceramics have garnered significant attention for their environmentally friendly attributes, desired piezoelectric activity (), and high Curie temperature (). However, the limited applicability of most KNN systems in high-power apparatus, including ultrasonic motors, transformers, and resonators, persists due to the inherent low mechanical quality factor (). Herein, we proposed an innovative strategy for achieving high accompanied by desirable via synergistic chemical doping and texturing in KNN piezoceramics.

Stereoselective Synthesis of Less Accessible α-Tertiary Amino Ketimines via Electrophilic Amination of α-Branched --Butanesulfinyl Ketimines.

A stereocontrolled electrophilic amination of α-branched --butanesulfinyl ketimines was developed to construct α-aminoketone derivatives containing less accessible α-tetrasubstituted stereocenters. Stereospecific α-deprotonation of ketimines with potassium -butoxide gave stereodefined metalloenamine intermediates that could act as nucleophiles to attack azodicarboxylic derivatives, affording α-aminated products in high yields with excellent stereoselectivities.

Montelukast, cysteinyl leukotriene receptor 1 antagonist, inhibits cardiac fibrosis by activating APJ.

Montelukast, cysteinyl leukotriene receptor 1 (CysLT1R) antagonist, is used clinically for patients with asthma, chronic obstructive pulmonary diseases (COPD), and allergic rhinitis. It has been reported that CysLT1R antagonists could reduce the risks of cardiovascular diseases in animal studies. Cardiac fibrosis is one of the major causes of heart failure.

Icotinib combined whole brain radiotherapy for patients with brain metastasis from lung adenocarcinoma harboring epidermal growth factor receptor mutation.

Background: The brain is a metastatic organ that is most prone to lung adenocarcinoma (LAC). However, the prognosis of patients with brain metastasis remains very poor. In this study, we evaluated the efficacy of icotinib plus whole brain radiation therapy (WBRT) for treating patients with brain metastasis from epidermal growth factor receptor (EGFR)-mutated LAC.

Decreased pretreatment serum cholesterol level is related with poor prognosis in resectable non-small cell lung cancer.

The cholesterol has been reported to be associated with cancer development. The aim of our study was to investigate the serum cholesterol level (TC) in non-small cell lung cancer (NSCLC) patients and their association with clinicopathologic parameters and the prognosis. The serum cholesterol levels were evaluated in 259 resected NSCLC patients and were correlated with clinicopathologic variables including age, gender, tumor size, regional lymph node metastasis, disease-free survival time and overall survival time.

The Association of Serum IL-33 and sST2 with Breast Cancer.

Breast cancer is one of the most common malignant diseases in women. The main cause of death from breast cancer is its metastases at distant sites in the body. Interleukin-33 (IL-33) is a cytokine of the IL-1 family and found overexpressed in various cancers.

SCYL1BP1 has tumor-suppressive functions in human lung squamous carcinoma cells by regulating degradation of MDM2.

SCY1-like 1-binding protein 1 (SCYL1BP1) is a newly identified transcriptional activator domain containing protein with many unknown biological functions. Recently emerging evidence has revealed that it is a novel regulator of the p53 pathway, which is very important for the development of human cancer. However, the effects of SCYL1BP1 on human lung squamous carcinoma cell biological behavior remain poorly understood.

[Long-term effects of video-assisted thoracoscopic thymectomy for myasthenia gravis: 5-year follow-up of 18 cases].

Objective: To evaluate the long-term effects of video-assisted thoracoscopic thymectomy for myasthenia gravis (MG).

Methods: Eighteen MG patients, 7 males and 11 females, aged 33.4 +/- 9.

Limb ischemic preconditioning induces brain ischemic tolerance via p38 MAPK.

It has been reported that limb ischemic preconditioning (LIP) could induce brain ischemic tolerance. In the present study, we investigated the role of p38 MAPK in the induction of brain ischemic tolerance by observing expression of phosphorylated p38 (p-p38) MAPK in the hippocampus after LIP and the effect of p38 MAPK inhibitor SB 203580 on the protection of LIP against delayed neuronal death (DND) in the CA1 hippocampus induced normally by brain ischemic insult. The results of Flow cytometry and Western blotting showed that expression of p-p38 MAPK initially increased at 6 h after LIP compared with sham group in the CA1 hippocampus.

The role of extracellular signal-regulated kinases in the neuroprotection of limb ischemic preconditioning.

To clarify the role of phosphorylated extracellular signal-regulated kinases (pERK1/2) in the neuroprotection of limb ischemic preconditioning (LIP) in rats, we investigated the expression of pERK1/2 using Western blot and flow cytometry in the hippocampus after LIP and the effect of pERK1/2 inhibitor PD 98059 on the neuroprotection of LIP against delayed neuronal death (DND) in the CA1 hippocampus normally induced by severe ischemic insult. It demonstrated that pERK1/2 in the hippocampus increased after LIP. In the CA1 hippocampus, ERK1/2 activation began to increase at 6h and reached peak at 12h after LIP, and decreased to sham level at 5d after LIP.
