Rare earth elements have many uses, and are frequently included in products such as fluorescent materials, hydride batteries, catalytic materials and lasers. In this study, it was observed that trivalent lanthanide ions (Ln[III] ions) appeared to inhibit the synthesis of large fragments in PCR assays, thus resulting in the preferential amplification of shorter sequences. It is therefore speculated that this Ln(III) ion-mediated bias could be utilized to improve the success rates for amplification of shorter products.

Hepatocellular carcinoma (HCC) ranks among the most prevalent types of cancer globally. Zinc finger protein 169 (ZNF169) holds significant importance as a transcription factor, yet its precise function in HCC remains to be elucidated. This study aims to examine the clinical importance, biological functions, and molecular pathways associated with ZNF169 in the development of HCC.

Human monkeypox (Mpox) is a zoonotic disease caused by the Monkeypox virus (MPXV). As of 14 August 2024, the World Health Organization (WHO) has declared it a global health emergency. For Mpox, this was the second public health emergency of global significance in the past two years.

Background: HER2 mutations are critical drivers of non-small cell lung cancer (NSCLC), affecting 2 %-3 % of patients and often leads to poor prognosis and limited response to conventional therapies. This study investigates the genomic characteristics and prognostic relevance of dynamic circulating tumor DNA (ctDNA) monitoring in advanced NSCLC patients with HER2 mutations treated with pyrotinib and apatinib.
Methods: The PATHER2 study included 33 advanced NSCLC patients harboring HER2 mutations or amplification, who received combination therapy of pyrotinib and apatinib.

Rolling circle amplification (RCA) is a widely used method for the synthesis of DNA nanoparticles and macro-hydrogels. Several strategies, including oscillation-promoted entanglement of DNA chains, multi-round chain amplification, hybridization between DNA chains, and hybridization with functional moieties, were applied to synthesize DNA macro-hydrogels; alternatively, flower-like nanoparticles were also produced. Here we report a straightforward yet effective method to manipulate the morphology of RCA products from nanoparticles to 3D hydrogels using an additional cold treatment step of the circular DNA template prior to elongation using phi29 DNA polymerase.

The impact of clinical stage on the effectiveness of osimertinib for epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) remains unexamined. We investigated osimertinib therapeutic efficacy variation between stage IVA or lower and stage IVB EGFR mutation-positive lung cancers, focusing on differences in pretreatment co-occurring genetic alterations in circulating tumor DNA. This was a secondary analysis of the ELUCIDATOR study, a multicenter prospective observational study in Japan that assessed the mechanisms underlying resistance to osimertinib as a first-line treatment for advanced NSCLC with EGFR mutations.
