The lysine-specific demethylase 5 (KDM5) family, a key post-translational modification of chromatin, can shape tumor immune microenvironment. Here, we performed an extensive clinical and bioinformatic analysis to explore the association between KDM5 mutation and tumor immunity and its impact on the outcomes in pan-cancer immunotherapy. In 2943 patients across 12 tumor types treated with immune checkpoint inhibitors, KDM5-mutant tumors were associated with favorable overall survival (hazard ratio, 0.

Exploring the nuanced and often elusive realm of pre-reflective consciousness presents a methodological challenge, as it involves capturing experiences that arise prior to reflective thought and language. This article introduces Phenomenological Mapping, an innovative research method designed to systematically study the pre-reflective dimensions of human experience. Grounded in the foundational theories of Edmund Husserl (2012), Maurice Merleau-Ponty (2013), and Martin Heidegger (1992, 2008), the approach also integrates contemporary perspectives from Dan Zahavi (1999, Contemporary Phenomenology and Qualitative Research 5(1), 1-17, 2021), Shaun Gallagher (2006, 2017), and Evan Thompson (2010, 2017).

Pre-eclampsia (PE) is a serious condition affecting 2-8% of pregnancies worldwide, leading to high maternal and fetal morbidity and mortality. MicroRNAs (miRNAs), small non-coding RNA molecules, have emerged as potential biomarkers for various pregnancy-related pathologies, including PE. MiRNAs in plasma and serum have been extensively studied, but urinary miRNAs remain underexplored, especially during early pregnancy.

Hepatocellular carcinoma (HCC) is the most common form of liver cancer in humans, with an increasing incidence worldwide. The current study aimed to explore the molecular mechanisms that inhibit the proliferation of HepG2 cells, a hepatoblastoma-derived cell line. MSC-derived exosomes (UC-MSCs) were prepared with a median particle size (N50) of 135.

In this study, 3,4-diaminobenzoic acid (DABA) was introduced into the porphyrin metal-organic framework (PCN-224) for the first time to prepare a ratiometric fluorescent probe (PCN-224-DABA) to quantitatively detect ferric iron (Fe(III)) and selenium (IV) (Se(IV)). The fluorescence attributed to the DABA of PCN-224-DABA at 345 nm can be selectively quenched by Fe(III) and Se(IV), but the fluorescence emission peak attributed to tetrakis (4-carboxyphenyl) porphyrin (TCPP) at 475 nm will not be disturbed. Therefore, the ratio of I/I with an excitation wavelength of 270 nm can be designed to determine Fe(III) and Se(IV).
