Synergy strategy of multi-metals confined in heteroatom framework toward constructing high-performance water oxidation electrocatalysts.

The development of a low-cost, highly active, and non-precious metal catalyst for oxygen evolution reaction (OER) is of great significance. Multi-metallic catalysts containing Fe, Co, and Ni exhibit remarkable OER activity, while the specific contributions of each component and the synergistic effects in the ternary metal catalyst has remained elusive. In this work, we synthesized a series of S and N-doped mono-metallic, bi-metallic, and tri-metallic hollow carbon sphere electrocatalysts (M-SNC) with the goal of enhancing the catalysts OER activity and shedding light on the unique roles and synergistic effects of the various metals in the FeCoNi ternary metal catalyst.

Diagnosis of a cystic lymphocyte-rich thymoma in a young cat.

Thymoma is one of the thymic epithelial tumors arising from the thymic epithelial cells of a variety of animal species including cat, cattle, dog, goat, horse, and pig. The cancer cells of thymoma are always localized within thymus. Feline thymoma was usually identified in the cranial mediastinum of elder cats.

Discovery and identification of natural alkaloids with potential to impact insulin resistance syndrome in Cyclocarya paliurus. (Batal) leaves by UPLC-QTOF-MS combined with HepG2 cells.

Cyclocarya paliurus (Batal.) leaves, which contain a range of bioactive compounds, have been used as a traditional Chinese medicine homologous food since ancient times. However, there is a paucity of literature on comprehensive studies of alkaloids in the leaves of Cyclocarya paliurus (Batal.

Unraveling the nuclear isotope tapestry: Applications, challenges, and future horizons in a dynamic landscape.

Nuclear isotopes, distinct atoms characterized by varying neutron counts, have profoundly influenced a myriad of sectors, spanning from medical diagnostics and therapeutic interventions to energy production and defense strategies. Their multifaceted applications have been celebrated for catalyzing revolutionary breakthroughs, yet these advancements simultaneously introduce intricate challenges that warrant thorough investigation. These challenges encompass safety protocols, potential environmental detriments, and the complex geopolitical landscape surrounding nuclear proliferation and disarmament.

Spatial metabolome of biosynthesis and metabolism in Cyclocarya paliurus leaves.

A large number of plant metabolites were discovered, but their biosynthetic and metabolic pathways are still largely unknown. However, the spatial distribution of metabolites and their changes in metabolic pathways can be supplemented by mass spectrometry imaging (MSI) techniques. For this purpose, the combination of desorption electrospray ionization (DESI)-MSI and non-targeted metabolomics was used to obtain the spatial distribution information of metabolites in the leaves of Cyclocarya paliurus (Batal.

Can new urbanization and ecological environment achieve synergistic development? Empirical evidence from 63 counties in Zhejiang, China.

As China's urbanization accelerates, ecological environmental issues have become increasingly prominent, and how to achieve the synergistic development of urbanization and ecological environment is worth exploring. The paper uses the Super-SBM model and the improved entropy method to calculate the ecological efficiency and the new urbanization in 63 counties in Zhejiang Province from 2000 to 2019. Furthermore, the coupling coordination degree between new urbanization and ecological efficiency is discussed with the coupling degree model, Markov chain, and spatial correlation methods, and its influencing factors are explored by the geographic detector.

Global Landscape of m6A Methylation of Differently Expressed Genes in Muscle Tissue of Liaoyu White Cattle and Simmental Cattle.

Liaoyu white cattle (LYWC) is a local breed in Liaoning Province, China. It has the advantages of grow quickly, high slaughter ratew, high meat quality and strong anti-stress ability. N methyladenosine (m6A) is a methylation modification of N position of RNA adenine, which is an important modification mechanism affecting physiological phenomena.

ECBC: Efficient Convolution via Blocked Columnizing.

Direct convolution methods are now drawing increasing attention as they eliminate the additional storage demand required by indirect convolution algorithms (i.e., the transformed matrix generated by the im2col convolution algorithm).

Astaxanthin Protects Ochratoxin A-Induced Oxidative Stress and Apoptosis in the Heart via the Nrf2 Pathway.

This study assessed the protective mechanism of astaxanthin (ASX) against ochratoxin A- (OTA-) induced cardiac injury in mice. Four groups of mice were established: control group (0.1 mL olive oil + 0.

Selenium-enriched yeast reduces caecal pathological injuries and intervenes changes of the diversity of caecal microbiota caused by Ochratoxin-A in broilers.

We investigated the protective effect and mechanism of selenium-enriched yeast (SY) on caecal injury induced by ochratoxin A (OTA) in broilers. Eighty broiler chickens of 1-day-old with similar weight were randomly assigned to Control group, OTA group, SY group and OTA + SY group, and were intragastricaly administered with OTA and SY for 21 consecutive days. The results showed that SY could reduce the caecal pathological injuries and could inhibit oxidative stress caused by OTA exposure.

A ZrO-RGO composite as a support enhanced the performance of a Cu-based catalyst in dehydrogenation of diethanolamine.

The sintering resistance of supported Cu nanoparticle (NP) catalysts is crucial to their practical application in the dehydrogenation of diethanolamine (DEA). In this paper, co-precipitation, hydrothermal synthesis, and sol-gel condensation are used to form a new support material through chemical bonding between graphene oxide and ZrO. The composite carriers prepared by the three methods are mixed with copper nitrate and ground using a ball mill.

Astaxanthin Protects OTA-Induced Lung Injury in Mice through the Nrf2/NF-κB Pathway.

The aim of this research was to evaluate the potential protective mechanism of astaxanthin (ASTA) against oxidative damage and inflammation caused by ochratoxin (OTA) in mouse lung. We divided mice into a control group (CG), an OTA group (PG), an astaxanthin group (AG), and an OTA+ASTA group (JG). Oxidative indices (malondialdehyde (MDA), total superoxide dismutase (T-SOD), and reduced glutathione (GSH)) and inflammatory markers (interleukin 1β (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α)) were assayed in the lung, and the lung-weight-to-body-weight ratio was calculated.

Microsatellite markers for the critically endangered elm species Ulmus gaussenii (Ulmaceae).

The Anhui elm Ulmus gaussenii is listed as a critically endangered species by the International Union for Conservation of Nature and is endemic to China, where its only population is restricted to Langya Mountain in Chuzhou, Anhui Province. To better understand the population genetics of U. gaussenii, we developed 12 microsatellite markers using an improved technique.

An extended affinity propagation clustering method based on different data density types.

Affinity propagation (AP) algorithm, as a novel clustering method, does not require the users to specify the initial cluster centers in advance, which regards all data points as potential exemplars (cluster centers) equally and groups the clusters totally by the similar degree among the data points. But in many cases there exist some different intensive areas within the same data set, which means that the data set does not distribute homogeneously. In such situation the AP algorithm cannot group the data points into ideal clusters.
