AI Article Synopsis
- LaBaCoMoO (LBCM) cathodes, synthesized using a sol-gel method, were tested for their effectiveness in intermediate-temperature solid oxide fuel cells.
- As molybdenum (Mo) content increased, thermal expansion decreased and conductivity improved, showing a significant impact on performance.
- The best-performing LBCM cathode (LBCM0.04) exhibited a notable reduction in polarization resistance and a substantial increase in maximum power density at 800 °C compared to the undoped version.
Article Abstract
LaBaCoMoO (LBCM, = 0-0.08) cathodes synthesized by a sol-gel method were evaluated for intermediate-temperature solid oxide fuel cells. The limit of the solid solubility of Mo in LBCM was lower than 0.08. As the content of Mo increased gradually from 0 to 0.06, the thermal expansion coefficient decreased from 20.87 × 10 K to 18.47 × 10 K. The introduction of Mo could increase the conductivity of LBCM, which varied from 464 S cm to 621 S cm at 800 °C. The polarization resistance of the optimal cathode LBCM0.04 in air at 800 °C was 0.036 Ω cm, reduced by a factor of 1.67 when compared with the undoped Mo cathode. The corresponding maximum power density of a single cell based on a YSZ electrolyte improved from 165 mW cm to 248 mW cm at 800 °C.

The impact of fetuin-A on predicting aortic arch calcification: secondary analysis of a community-based survey.

Article Synopsis
- Atherosclerotic cardiovascular disease has a high mortality rate linked to vascular calcification, with fetuin-A's role in aortic arch calcification (AAC) not fully understood.
- An analysis of 800 individuals revealed that those with AAC had higher blood pressure and lower fetuin-A levels, indicating a connection between these factors.
- The findings suggest that low fetuin-A levels and high systolic blood pressure can more accurately predict AAC, highlighting the importance of these biomarkers in cardiovascular health.
Background: Abdominal aortic calcification (AAC) pathogenesis is intricately linked with inflammation. The pan-immune-inflammation value (PIV) emerges as a potential biomarker, offering reflection into systemic inflammatory states and assisting in the prognosis of diverse diseases. This research aimed to explore the association between PIV and AAC.

The structural changes that accompany the dehydration of NaPtX·6HO (X = Cl, Br) were studied using in situ variable temperature synchrotron X-ray diffraction. The two hexahydrates are isostructural, containing isolated Pt octahedra separated by Na cations. Removal of the water results in the formation of the anhydrous vacancy ordered double perovskites NaPt.

Background: Pemetrexed is an efficacious multi-targeted antifolate with acceptable toxicity for non-squamous non-small cell lung cancer (non-Sq NSCLC) and malignant pleural mesothelioma. Vitamin B12 and folic acid as premedication can reduce the frequency of severe toxicities of pemetrexed chemotherapy. However, adverse effects are frequent in clinical settings.

Introduction: Parathyroid hormone-lowering responses after administration of three different therapies capable of raising serum total 25-hydroxyvitamin D (25OHD) were evaluated in patients with secondary hyperparathyroidism (SHPT), vitamin D insufficiency (VDI), and stage 3 or 4 chronic kidney disease (CKD).
Methods: Sixty-nine adult subjects with intact parathyroid hormone (iPTH) ≥85 and <500 pg/mL and VDI (25OHD <30 ng/mL) were randomized after ≥4-week washout to 2 months of open-label treatment with: (1) extended-release calcifediol (ERC) 60 μg/day; (2) immediate-release calcifediol (IRC) 266 μg/month; (3) high-dose cholecalciferol (HDC) 300,000 IU/month; or (4) paricalcitol plus low-dose cholecalciferol (PLDC) 1 or 2 μg and 800 IU/day, used as reference hormone replacement therapy. Serum 25OHD, calcium (Ca), phosphorus (P), plasma iPTH, and adverse events were monitored weekly.
