Summary: Unrecognized immunodeficiency may contribute to antibiotics' failure in treating Lyme disease symptoms. The study showed that the efficacy of doxycycline was significantly lower in mice lacking adaptive immunity, especially B cells, with the most pronounced effect seen in immunodeficient C3H mice. Additionally, the addition of a single dose of ceftriaxone to doxycycline treatment effectively cleared infection in severely immunodeficient C3H mice.

Summary: This study used metabolomics to analyze metabolic responses in patients with Post-treatment Lyme disease symptoms/syndrome (PTLDS) compared to clinically cured non-PTLDS patients. The findings revealed observable metabolic differences between PTLDS and non-PTLDS patients at multiple time points, with distinct patterns of metabolite abundance. A small number of metabolites could be used to define PTLDS versus non-PTLDS patients at specific time points, and these findings were validated in a second patient cohort. These results suggest that metabolite-based measurement can help distinguish patients with PTLDS and provide insights into the underlying biochemistry of PTLDS.

Summary: Lyme disease in the United States is mainly caused by Borrelia burgdorferi sensu stricto. After a tick bite, patients may develop erythema migrans. If dissemination occurs, neurologic manifestations, carditis, or arthritis may follow. OspC, a surface protein, is essential in early infection, but it is not the sole determinant of dissemination.

Summary: Lyme disease, caused by Borrelia burgdorferi infection, presents with well-defined symptoms that can be treated with appropriate antibiotics. However, some patients may experience persistent nonspecific symptoms after treatment. Posttreatment Lyme disease syndrome is a diagnosis of exclusion and requires careful evaluation to avoid overdiagnosis and overtreatment.

Summary: The deficiency of 12/15-lipoxygenase (12/15-LO) exacerbates ankle swelling and arthritis severity in Lyme arthritis, suggesting that 12/15-LO lipid metabolites play a crucial role in resolving inflammatory arthritis. Therapeutic treatment with lipoxin A4 (LXA(4)) can alleviate joint edema and pain in Lyme arthritis patients.

Summary: RNA interference (RNAi) is a versatile method for regulating gene expression. Endogenous microRNAs (miRNAs) and exogenous small interfering RNAs (siRNAs) form RNA-induced silencing complexes to achieve gene regulation. RNAi-based drugs have been approved for clinical use and advancements in technology aim to improve their efficacy and safety. Chemical modifications and delivery platforms are being explored to enhance the structure, stability, and activity of RNA molecules. Novel biologic RNAi agents are also being developed for research purposes.

Summary: An efficient hierarchical porous carbon catalyst for the oxygen reduction reaction was developed in this study through a simple solid-phase synthesis method. The introduction of zinc helped inhibit nanoparticle growth and agglomeration, leading to the formation of active nitrogen species and porosity, thereby enhancing the catalytic activity. The optimized FeZn-N-C-1 catalyst exhibited a high half-wave potential and demonstrated promising performance as a cathode in a zinc-air battery.

Summary: Six long-offset multi-channel seismic profiles were reprocessed to generate pre-stack depth migration (PSDM) sections from TAIGER experiment in 2009 and TAICRUST project in 1995. Two velocity-interface models were obtained, considering the PSDM sections and previous tomography models. The subduction of Gagua Ridge caused uplift of sedimentary basement and lower crustal structure beneath the Nanao Basin, as indicated by the PSDM sections and velocity-interface models. A recent earthquake near Taiwan's northeast coast in 2018 at a depth of approximately 12 km below the Hsincheng Ridge was likely caused by a thrust fault near the decollement formed by the subduction of the Philippine Sea Plate.

Summary: This study reports the co-doping of Zr and Fe dual metal sites into a ZIF-8-derived mesoporous carbon for improved durability and activity in the oxygen reduction reaction. The Zr-doped Fe-N-C catalyst showed only 25% voltage loss after 20 hours of continuous operation and retained 40% of its initial performance after 100 hours, outperforming the catalyst without Zr doping. The cathode also exhibited significantly enhanced ORR activity, achieving a maximum power density of 0.72 W cm-2.

Summary: Driven by host-pathogen coevolution, cell surface antigens are the fastest evolving parts of microbial pathogens. Novelty-seeking algorithms are useful in predicting antigen diversification in these pathogens. A hybrid algorithm combining fitness- and novelty-seeking strategies showed the best performance in predicting variant fitness peaks. The efficiency of the hybrid algorithm improves the predictability of novel antigen variants.

Summary: The research found that miR-22-3p, miR-9-5p, and miR-218-5p are antiproliferative miRNAs targeting non-small cell lung cancer (NSCLC) cells, and they inhibit folate metabolism and alter amino acid metabolism in NSCLC cells. In addition, the inhibition of glucose uptake by miR-22-3p and the reduction of serine biosynthesis from glucose by miR-9-5p and -218-5p were also confirmed. Recombinant miR-22-3p was more effective than miR-9-5p and -218-5p in inhibiting NSCLC cell respiration, glycolysis, and colony formation, without causing any toxicity.

Summary: Metal-nitrogen-carbon (M-Nx-C) catalysts possess high reactivity, selectivity, and ease of synthesis, and show potential to replace platinum-based catalysts. However, they face limitations in application due to low active site density and insufficient durability in the oxygen reduction process of fuel cells. Doping with various metal/nonmetal elements to modulate the electronic structure and spatial configuration of the active site has been found to greatly enhance the performance and stability of M-Nx-C catalysts, making it a popular research topic in the field.
