Summary: The study showed that β-glucan can reduce inflammation and tissue damage in treating otitis media in experimental animals. Compared to antibiotics alone, the combination of β-glucan and antibiotics can further alleviate the severity of the condition.

Summary: This study reviewed the effects of functional orthodontic appliances in treating pediatric obstructive sleep apnea. The results showed that these appliances improved the apnea-hypopnea index and respiratory function in the short term. However, there are significant deficiencies in the existing evidence, including lack of control groups, small sample sizes, lack of randomization, and absence of long-term results.

Summary: DNA dynamics determine the frequency of A G mismatch and explain the high frequency of 8OG A similar to 8OG misincorporation. NMR measurements show the presence of Aanti+(Gsyn) and Asyn Ganti Hoogsteen conformations in low abundance. The presence of 8OG redistributes the ensemble, favoring the mutagenic Aanti 8OG(syn) Hoogsteen state, leading to increased replicative errors.

Summary: This article introduces Leonardo da Vinci's predecessors in light propagation research, analyzes his drawings on reflecting light by a spherical mirror, and presents his discovery and the related description of energy concentration. The article also explains the observed sound focus in existing halls and the determination of mirror aperture size. Finally, the implementation of these improvements is shown through specific examples.

Summary: This study explored the mechanism of native dispersion in Pseudomonas aeruginosa PAO1 biofilms by comparing it with dispersion induced by exogenous cues. The findings suggest that while the sensing of native and exogenous dispersion cues may be distinct, the downstream mechanisms leading to biofilm cell liberation and dispersion rely on a shared pathway.

Summary: Micro energy-dispersive X-ray fluorescence spectrometry was used to characterise copper-based objects recovered from the neighbouring roman sites of Moinho do Castelinho and Quinta da Bolacha (Lusitania province) during archaeological works. The study found a diversified metallurgy in these artifacts, with different alloys selected based on their functionality and containing various minor elements. The choice of alloys for everyday objects reflected technological, symbolic, and economic considerations.

Summary: Leonardo Da Vinci left many clues, rules and knowledge about the consequences of friction and methods to reduce it in his manuscripts. The Italian polymath studied aspects related to wear, lubrication, and contact mechanics, which form the basis of modern tribology. His knowledge, obtained through intuitive means, led to solutions and concepts without complex processes of reasoning. Through sketches and reflections, Da Vinci enhanced his understanding of the origin and consequences of relative movement between bodies, showing the importance in present-day tribology.

Summary: Conventional PLS-DA and sparse sPLS-DA were effectively used to authenticate avocado samples by analyzing lipid chromatographic fingerprints. The concatenated classification models successfully resolved multiclass problems in food authentication, with performance metrics around 0.95 for both multivariate classification methods.

Summary: The review focuses on Leonardo da Vinci's work and thought related to fluid mechanics, highlighting his use of experimentation as an important mechanism for natural fluid flows. However, it points out that his conclusions did not always align with modern fluid mechanics. Leonardo's works depict multiple and ambiguous meanings of turbulence, while also exploring concepts similar to modern ideas.

Summary: HBV infection is a serious global health issue, and it can lead to complications such as liver cirrhosis and hepatocellular carcinoma. New serum markers, including the 4210 Da and 1866 Da polypeptides, have been found to have good diagnostic value for HBV-related liver diseases. These biomarkers can help guide treatment and predict clinical outcomes accurately.

Summary: In this study, a new model called DA-Res2UNet is proposed to improve the accuracy of blood vessel segmentation by effectively extracting multiscale information using Res2block and Dual Attention techniques. The model’s ability to identify blood vessels is explained using a pre-trained fundus image generator, and the dataset is adjusted to reduce misidentification. The model achieves state-of-the-art F1-score on different datasets.

Summary: In this study, a multi-functional injectable hydrogel was prepared and its antioxidant, gelation time, degradability, rheology, and antihemorrhagic properties were finely tuned by varying the composition ratio. The hydrogel was found to promote angiogenesis and cell proliferation, and regulate inflammation to enhance the repair of full-thickness skin injuries.
