The invention and development of new research concepts, novel methodologies, and novel bioanalytical techniques are essential in advancing the animal sciences, which include feed and nutrition science. This article introduces a novel approach that shows the potential of advanced synchrotron-based bioanalytical technology for studying the effects of molecular structural changes in feeds induced by various treatments （e.g., genetic modification, gene silencing, heat-related feed processing, biofuel processing） in relation to nutrient digestion and absorption in animals. Advanced techniques based on synchrotron radiation （e.g., synchrotron radiation infrared microspectroscopy （SR-IMS） and synchrotron radiation X-ray techniques） have been developed as a fast, noninvasive, bioanalytical technology that, unlike traditional wet chemistry methods, does not damage or destroy the inherent molecular structure of the feed. The cutting-edge and advanced research tool of synchrotron light （which is a million times brighter than sunlight） can be used to explore the inherent structure of biological tissue at cellular and molecular levels at ultra-high spatial resolutions. In conclusion, the use of recently developed bioanalytical techniques based on synchrotron radiation along with common research techniques is leading to dramatic advances in animal feed and nutritional research.

Objective Oil and gas are abundant in the Ordovician Yingshan Formation carbonate karst reservoirs on the northern slope of Tazhong uplift in the Tarim Basin, and have extremely complicated oil-gas-water distribution, however. The difference in burial depth of the reservoirs between east and west sides is up to 1000 m. water-bearing formations exist between oil- and gas-bearing formations vertically and water-producing wells are drilled between oil- and gas-producing wells. Macroscopically, oil and gas occur at low positions, while water occurs at high positiona on the northern slope of Tazhong uplift. The mechanism of differential hydrocarbon enrichment in heterogeneous reservoirs is by far not clarified, which has affected the efficient exploration and development of oil and gas fields in this area.

To most well-informed scientists who do not work on bone, the idea that bones determine anything other than your posture and location for the miseries of arthritis would come as quite a surprise. It would be like imagining that the walls of our home played something more than a passive role in the complexities of the lives conducted within. Yet something precisely as radical as that is what Karsenty and his colleagues boldly imagined,1 and then provocatively established in a series of studies over the past decade.20steocalcin （OCN） is a vitamin K- dependent peptide hormone secreted by the bone-formine osteoblasts.

The metal-organic frameworks (MOFs) have the characteristics of high porosity and crystallinity, which also makes MOFs have the advantages of high sensitivity, high selectivity and high efficiency in the field of fluorescence sensing. It can detect the target substance efficiently and quickly, and has excellent anti-interference. Therefore, MOFs materials are also considered as ideal materials for fluorescence sensors. This paper introduces three common preparation methods of MOFs materials: hydrothermal/solvothermal method, mechanochemical method and microwave method. we focus on the application status of MOFs materials in the three fluorescence sensing fields of small molecules, metal cations and inorganic anions, as well as the shortcomings and improvement methods of MOFs materials in this application field. Finally, in view of the shortcomings of MOFs materials in the field of fluorescence sensing, such as poor stability, fluorescence quenching phenomenon susceptible to environmental interference, etc., it is proposed that more in-depth research should be carried out in the future in terms of anti-interference and reuse © 2024, Department of Chemistry, Northeast Normal University.

A computer-assisted method is presented for optimization of mobile phase compositions and development distance in gradient two-step development HPTlC. The method is based on a system which can predict the final R(f) values for gradient two-step development from values measured using five preliminary runs. The statistical scanning method is then used for optimization, using R(f) difference as the selection criterion. The method was evaluated using a mixture of eight components. Excellent agreement was obtained between predicted and experimental results.

A simulated experimental reduction of and the synthesis of uraninite by a sulfate-reducing bacteria, Desulfovibrio desulfuricans DSM 642, are first reported. The simulated physicochemical experimental conditions were: 35°C, pH=7.0-7.4, corresponding to the environments of formation of the sandstone-hosted interlayer oxidation-zone type uranium deposits in Xinjiang, Nw China. Uraninite was formed on the surface of the host bacteria after a one-week's incubation. Therefore, sulfate-reducing bacteria, which existed extensively in Jurassic sandstone-producing environments, might have participated in the biomineralization of this uranium deposit. There is an important difference in the order- disorder of the crystalline structure between the uraninite produced by Desulfovibrio desulfuricans and naturally occurring uraninite. long time and slow precipitation and growth of uraninite in the geological environment might have resulted in larger uraninite crystals, with uraninite nanocrystals arranged in order, whereas the experimentally produced uraninite is composed of unordered uraninite nanocrystals which, in contrast, result from the short time span of formation and rapid precipitation and growth of uraninite. The discovery has important implications for understanding genetic significance in mineralogy, and also indicates that in-situ bioremediation of U-contaminated environments and use of biotechnology in the treatment of radioactive liquid waste is being contemplated.
