Harnessing autophagy: A potential breakthrough in digestive disease treatment

Autophagy,a conserved cellular degradation process,is crucial for various cellular processes such as immune responses,inflammation,metabolic and oxidative stress adaptation,cell proliferation,development,and tissue repair and remodeling.Dysregulation of autophagy is suspected in numerous diseases,including cancer,neurodegenerative diseases,digestive disorders,metabolic syndromes,and infectious and inflammatory diseases.If autophagy is disrupted,for example,this can have serious consequences and lead to chronic inflammation and tissue damage,as occurs in diseases such as Chron's disease and ulcerative colitis.On the other hand,the influence of autophagy on the development and progression of cancer is not clear.Autophagy can both suppress and promote the progression and metastasis of cancer at various stages.From inflammatory bowel diseases to gastrointestinal cancer,researchers are discovering the intricate role of autophagy in maintaining gut health and its potential as a therapeutic target.Researchers should carefully consider the nature and progression of diseases such as cancer when trying to determine whether inhibiting or stimulating autophagy is likely to be beneficial.Multidisciplinary approaches that combine cutting-edge research with clinical expertise are key to unlocking the full therapeutic potential of autophagy in digestive diseases.

Physics-based Modeling and Simulation for Motional Cable Harness Design

The design work of motional cable in products is vital due to the difficulty in estimating the potential issues in current researches.In this paper,a physics-based modeling and simulation method for the motional cable harness design is presented.The model,based on continuum mechanics,is established by analyzing the force of microelement in equilibrium.During the analysis procedure,three coordinate systems：inertial,Frenet and main-axis coordinate systems are used.By variable substitution and dimensionless processing,the equation set is discretized by differential quadrature method and subsequently becomes an overdetermined nonlinear equation set with boundary conditions solved by Levenberg-Marquardt method.With the profile of motional cable harness obtained from the integral of arithmetic solution,a motion simulation system based on＂path＂and＂profile＂as well as the experimental equipments is built.Using the same parameters as input for the simulation and the real cable harness correspondingly,the issue in designing,such as collision,can be easily found by the simulation system.This research obtains a better result which has no potential collisions by redesign,and the proposed method can be used as an accurate and efficient way in motional cable harness design work.

Dynamic Simulation and Disturbance Torque Analyzing of Motional Cable Harness Based on Kirchhoff Rod Model

The motional payloads on stabilized platform must be linked by some cable harnesses with other immobile apparatus.During the operation of stabilized platform,these cable harnesses can create spring disturbance torque which is exerted on the stabilized platform and then reduce the stabilizing precision.None of current studies can deal with the spring disturbance torque problem.To analyze the spring disturbance toque,a dynamic thin rod model is presented for simulating the motional cable harness which is based on the Kirchhoff rod theorem and can consider the geometrically non-linear effects.The internal bending and torsion restoring torques are simulated and then a predictive analysis of the disturbance torque can be performed in motional cable routing design.This model is solved with differential quadrature method（DQM）.By using zeros of the Chebyshev polynomial as the grid points,the arc-coordinate is discretized to obtain a set of ordinary differential equations in time domain which is solved by implied method to obtain the profile and internal force of cable harness.The accuracy of this model is validated by comparing the simulation results and the experiment results（both the spring force and the deformed profile of the motional cable harness）.In the experiment,a special optical measuring instrument based on binocular vision is developed.The comparison of experimental and simulated results shows that the simulation model can represent the real motional cable harness well,and the spring disturbance force simulation results are precise enough for spring disturbance torque analysis.This study will be helpful to obtain an optimized motional cable harness layout design with small spring disturbance torque.

A comparative evaluation of methicillin-resistant staphylococci isolated from harness racing-horses,breeding mares and riding-horses in Italy

Objective:To investigate the prevalence of methicillin-resistant staphylococci(MRS)which is a potencial risk factor of transmission between animals and humans in different types of horses(harness racing-horses,breeding mares and riding-horses)and to compare the antimicrobial resistance of the isolates.Methods:A total of 191 healthy horses,housed at different locations of the Campania Region(Italy),were included in the study.Nasal swab samples were collected from each nostril of the horses.The mecA gene was detected by a nested PCR technique.Antibiotic susceptibility was tested for each isolate.Results:MRS was isolated from nasal samples of 68/191(35.6%;95%CI:28.9%-42.9%)healthy horses.All isolates were coagulase-negative with the exception of two coagulase-positive MRS strains,identified as Staphylococcus aureus and Staphylococcus pseudintermedius.2/83(2.4%;95%,CI:0.4%-9.2%).Interestingly,both coagulase-positive MRS isolates were from harness racing-horses.These horses also presented a significantly higher positivity for MRS(53.3%;95%CI:40.1%-66.1%)than the breeding mares and riding-horses groups.Antibiotic susceptibility testing showed difference between isolates due to different origins except for an almost common high resistance to aminopenicillins,such as ampicillin and amoxicillin.Conclusions:It can be concluded that harness racing-horses may act as a significant reservoir of MRS as compared to breeding mares and riding-horses.

Cable Harness Assembly Planning in Virtual Environment

Based on the analysis of characteristic of cable harness planning in virtual environment,a discrete control node modeling (DCNM) method of cable harness in virtual environment and the cable harness assembly routing technique based on it are proposed. DCNM converts a cable harness into continuous flexed line segments connected by a series of section center points,and the design can realize cable harness planning through controlling those control nodes. This method of cable harness routing in the virtual environment breaks the status that virtual assembly process planning is just suitable for the rigid components at present,and impulse the virtual assembly process planning to be more practical. Relation algorithms have been verified in a self-developed system named virtual cable harness assembly planning (VCHAP) system,and this VCHAP system has been applied in assembly process planning of aerospace-related products.

A new technology for harnessing the dye polluted water and dye collection in a chemical factory

A new technology for harnessing the dye polluted water and dye collection was developed. It is based on the enhanced evaporation by using solar, wind and air temperature energy and additional heat-electric energy. It consists of four parts: (1) evaporation carrier system (evaporation carrier and frame for evaporation carrier) for polluted water; (2)polluted water circulating system (pumping-spraying-collecting); (3)heating system; (4)workshop with polluted water reservoir-tanks and rainfall prevention roof. The polluted water was (heated in case necessary) sprayed to the evaporation carrier system and the water was evaporated when it moved in the space and downward along the carrier mainly by using natural (solar, wind and air temperature energy). In case, when there is no roof for the carrier system, the polluted water can be stored in the reservoirs (storage volume for about 20 days). The first 10-25 mm rainfall also need to be stored in the reservoirs to meet the state standard or discharging wastewater. The dye may be collected at the surface in the reservoir-tanks and the crystallized salt may be collected at the bottom plate. The black-color wastewater released by the factory is no more discharged to the surface water system of Taihu Lake Basin. About 2 kg dye and 200 kg industrial salt may be collected from each tone of the polluted water. The non-pollution production of dye may be realized by using this technology with environmental, economical and social benefits.

Metallic Reserves of Submarine Manganese Nodules to be Estimated and Harnessed Prudently: Evidence from China's Jiaolong Manned Submersible

Since the discovery of oceanic manganese nodules during the expedition of the British ocean-going ship Challenger from 1872 to 1876, research and development for seabed manganese nodules have never ceased owing to the huge economic inducements. Manganese nodules are the black or dark brown, spherical or massive Mn-bearing ores, deposits of which are found on the sea bottom. The nodules are a mixture of silicate and insoluble potassium permanganates （also with sub-Ti, Fe and Na permanganates） that contain more than 30 kinds of metallic elements, among which those of greatest economic interest are Mn （27-30%）, Ni（1.25-1.5%）, Cu（1- 1.4%）, Co（0.2- 0.25 %）, Fe, Si, and AI, with minor amounts of Ca, Na, K, Ti, B, H and O.
