Abstract: An analysis method for optimizing number and position of screws used in long bone (fracture fixation) surgery, including the following steps. Perform a CT scan on a surgical patient to obtain a medical image to build a long bone 3D model. Analyze an X-ray image to obtain a long bone fracture condition and a bone quality condition. Select a bone plate 3D model from the model database. Import the bone plate 3D model into the long bone 3D model and set an initial fixation position of the bone plate 3D model. Instruct the first artificial intelligence to comprehensively analyze the conditions to automatically select alternative solutions in the model database. Then, use a computer-aided analysis system to analyze the stress distribution of the alternative solutions, and a first preferred solution is obtained through simulating analysis, thereby excluding incorrect or ineffective surgical plans to reduce the analysis time and patient wait time and increasing the surgery success rate.

Abstract: Disclosed are emulsion gel with both a freshness indication and a low migration rate, and a preparation method therefor. Lipase and organic acid are used and subjected to hydrophobic modification of anthocyanins to obtain acylated anthocyanins, the acylated anthocyanins and oil-phase gel are then dissolved in vegetable oil to form an oil phase, while a sodium alginate aqueous solution is used as a water phase, the oil phase and the water phase are mixed and subjected to high-speed shearing, and calcium carbonate and glucono-?-lactone are finally added for high-speed shearing to form emulsion gel. The emulsion gel prepared in the present disclosure has both a freshness indication and a low migration rate, and the preparation method of the present disclosure is simple, green, pollution-free and low energy consumption.

Abstract: The present disclosure describes methods for detecting, monitoring, and modulating (e.g., promoting, enhancing, sustaining, maintaining, reducing, mitigating or eliminating of) biofilm formation, as well as mitigating or eliminating Microbial Influenced Corrosion (MIC) of a metal surface. The method of monitoring includes: providing a test sample; detecting at least one of a prophage gene, a prophage gene expression, a prophage gene transcript, a prophage protein, a prophage metabolite, a prophage intermediate, or a combination thereof, wherein the existence, amount or level of prophage gene expression, a prophage gene transcript, a prophage protein, a prophage metabolite, a prophage intermediate, or a combination thereof relative to a control is indicative of biofilm presence, formation or the state of the biofilm in a sample. The present disclosure also describes a composition for modulating biofilm formation, maintenance, mitigation, reduction, and elimination.

Abstract: Provided are methods for mitigating or eliminating Microbial Influenced Corrosion of a metal surface including contacting the metal surface with an effective amount of a liquid composition comprising indole or a functionally equivalent analog or derivative thereof. Also provided are methods for reducing the formation or activity of a corrosion-associated biofilm on a metal surface including contacting the metal surface with an effective amount of a liquid composition including indole or a functionally equivalent analog or derivative thereof.
