Obesity is widely recognized as a public health problem around the world. In the human body, it is not only shown by excessive accumulation of fat tissue, but is also closely related to a state of chronic low-grade inflammation. In recent years, studies have found that the abnormal function of fat tissue caused by obesity can promote the release of inflammatory factors, which can further lead to insulin resistance, abnormal lipid metabolism, and other metabolic problems. As a result, obesity and chronic inflammation can form a vicious cycle in which they continue to worsen each other. Omega-3 fatty acids, as essential unsaturated fatty acids, have the potential to regulate inflammatory responses and improve metabolic function. This paper uses a literature review to summarize the mechanisms behind obesity-related chronic inflammation and analyze the possible ways Omega-3 fatty acids may reduce inflammation and improve metabolic problems. Based on existing clinical trial results, this paper discusses whether Omega-3 can effectively improve obesity-related problems by reducing chronic inflammation, as well as whether it has a direct effect on weight loss. Research has found that Omega-3 fatty acids can improve the metabolic condition of people with obesity by lowering the levels of pro-inflammatory factors, improving the inflammatory environment of fat tissue, and increasing insulin sensitivity. However, current clinical evidence does not prove that Omega-3 has a significant direct effect on weight loss. Therefore, Omega-3 is more suitable as an additional nutritional intervention in obesity management rather than as a product directly used for fat loss.

Rheumatoid arthritis is a sysrenmic autoimmune disease which mainly affects joints that affects millions of patients in the world. Protein therapeutic is one of the important treatment against this disease. In order to perform precised protien delivery, engineered exosomes are significant tools. This review includes the pathophysiology of rheumatoid arthritis and therapeutic targets, introduction of exosomes, strategies of engineering exosomes and the evaluation of engineered exosome-based protein drug delivery systems. The research shows that exosome is a good material for target protein delivery due to its accuracy and biocompatibility. The efficiency is significantly increased comparing with other delivery system. However, there are still some limitation for this method, such as high cost and low cargo loading efficiency. This review calls for the medical industry's attention on this kind of new technique to improve the engineeringf strategies and reduce the costs, in order to put this method in use for more patients.

Many people, such as students and office workers, sleep little on weekdays but sleep much longer on weekends. People believe extra weekend sleep can fully repair the damage caused by irregular daily sleep and broken body clocks, which is called social jetlag. This paper uses basic sleep science and simple experiment results to check if this idea is true. Human sleep has two control systems: sleep pressure and the 24-hour body clock. Weekend sleep can ease tiredness from short weekday sleep for a short time by making deep sleep longer. However, if people wake up over two hours later on weekends, their body clocks will become more disordered. Three natural biological limits stop weekend sleep from fixing long-term clock damage. In short, sleeping in on weekends cannot fully heal health problems from messy weekday sleep. Keeping a steady sleep time every day is the better choice. This paper may give easy sleep tips for students and adults and help protect their body clocks.

This paper investigates two distinct protocols and one combined protocol for image teleportation based on three quantum states. It begins by reviewing key linear algebraic concepts and formalized quantum states in Hilbert space. Building on this, it analyzes a variation of dense coding using non-maximally entangled (polluted) states. It demonstrates that while full distinguishability of four Bell-like states is lost under entanglement degradation, it is possible to design a restricted set of operations that maximizes distinguishability; it designs a new protocol of superdense coding based on three Bell states. In the next section of the article, it introduces a three-level energy system and designs a quantum teleportation protocol based on the three states. It also introduces the HSV color model, which features three parameters that are used to represent a color. With such a protocol, it can teleport a color with high confidence and security. Both of these protocols can be used for image teleportation technologies. Finally, it integrates the superdense coding protocol and the quantum teleportation protocol to create a highly theoretical image teleportation protocol that can perform filtering, encoding and decoding, and emergency destruction on colored images with enhanced security. An additional participant is added, so that the quantum state will be modified during the teleportation process by this new participant. All of these protocols can be applied in future image teleportation techniques.
