Dynamics of measurable residual disease for risk stratification and guiding allogeneic transplant in acute myeloid leukaemia patients with myelodysplasia-related mutations in first remission.

Accurate classification and risk prediction are critical for therapeutic decision-making in patients with acute myeloid leukaemia (AML). Myelodysplasia-related (MR) gene mutations are classified as adverse genetic factors by the European LeukaemiaNet-2022 guidelines. However, their prognostic value in de novo AML remains controversial.

Determining optimal clinical target volume margins based on microscopic extracapsular extension of metastatic nodes in patients with non-small-cell lung cancer after chemotherapy or chemotherapy combined with immunotherapy.

Background: No standard has been established for the clinical target volume (CTV) margins of lymph nodes (LNs) in patients with non-small-cell lung cancer (NSCLC) receiving chemotherapy or chemotherapy combined with immunotherapy followed by radiotherapy. This study aimed to discuss the CTV range of NSCLC after chemotherapy or chemotherapy combined with immunotherapy by observing the microscopic extent of tumor spread beyond the LN capsule.

Methods: We retrospectively analyzed the data of 240 patients with stage II and III NSCLC who underwent surgery without neoadjuvant therapy, with neoadjuvant chemotherapy (NAC), or with NAC combined with immunotherapy (NACI).

A new thermochromic crystal violet lactone/lactic acid/myristyl alcohol ternary mixture encapsulated with a poplar-based cellulose/lignin/SiO framework.

Two thermochromic poplar-based composites, TPC-1 and TPC-2, were fabricated using a crystal violet lactone (CVL)/lactic acid/myristyl alcohol ternary mixture. The mass ratios for TPC-1 and TPC-2 were 10: 3: 200 and 10: 80: 200, respectively. TPC-1 exhibits a common thermochromic property, reversibly changing color from blue to the natural hue of poplar within the temperature range of 28-48 °C.

N-Methyladenosine Modification-Related Genes Express Differentially in Sterile Male Cattle-Yaks.

N-methyladenosine (mA), an RNA post-transcriptional modification, plays a crucial role in spermatogenesis. Cattle-yaks are interspecific hybrid offsprings of yak and cattle, and male cattle-yaks are sterile. This study aims to investigate the role of mA modification in male cattle-yak infertility.

EGCG inhibits migration, invasion and epithelial-mesenchymal transition of renal cell carcinoma by activating TFEB-mediated autophagy.

Background: The incidence of renal cell carcinoma (RCC) is already in the top ten of all types of cancers, with more than 4 %. Epigallocatechin gallate (EGCG), a polyphenolic compound extracted from green tea, has been shown to be effective in the treatment of various tumors. However, limited studies have demonstrated the effect of EGCG on RCC and its underlying molecular mechanisms.

Intelligent Analysis of Avian Influenza Virus Biomarkers Based on Chemiluminescence Resonance Energy Transfer and DNA Logic Analysis.

A one-step logical analysis of multiple targets remains challenging. Herein, we report a one-pot and intelligent DNA logical analysis platform for the diagnosis of avian influenza virus (AIV) biomarkers based on chemiluminescence resonance energy transfer (CRET) and logic operations. On the surface of Lum/PEI/CaCO microparticles, the excited state of luminol underwent CRET with fluorescein isothiocyanate or rhodamine B isothiocyanate, producing three well-separated light emissions at 425, 530, and 590 nm, respectively.

The deubiquitinase OTUD5 stabilizes SLC7A11 to promote progression and reduce paclitaxel sensitivity in triple-negative breast cancer.

Ferroptosis is a newly defined form of programmed cell death characterized by iron-dependent lipid peroxide accumulation and is associated with the progression of cancer. Solute carrier family 7 member 11 (SLC7A11), a key component of cystine/glutamate antiporter, has been characterized as a critical regulator of ferroptosis. Although many studies have established the transcriptional regulation of SLC7A11, it remains largely unknown how the stability of SLC7A11 is regulated in cancers, especially in triple-negative breast cancer (TNBC).

Determinants of spatiotemporal changes of land use carbon emissions for counties in Shaanxi Province, China.

In China, urban sprawl and developed land expansion challenge the country's "carbon peak" and "carbon neutrality" goals. Counties as the basic governance units are crucial for effective carbon reduction policies. This study examines land use carbon emissions (LUCE) in Shaanxi Province at the county level, essential for China's low-carbon strategy.

Transcriptome dynamics in provides new insights into cold adaptation and de-adaptation.

Plants adapt to cold stress through a tightly regulated process involving metabolic reprogramming and tissue remodeling to enhance tolerance within a short timeframe. However, the precise differences and interconnections among various organs during cold adaptation remain poorly understood. This study employed dynamic transcriptomic and metabolite quantitative analyses to investigate cold adaptation and subsequent de-adaptation in , a species known for its robust resistance to abiotic stress.

Blue emission-dominated NaYbF@NaYF:2%Ho@NaYF upconversion nanoparticles for detecting ascorbic acid.

The blue emission-dominated NaYbF@NaYF:2%Ho@NaYF (CSS) upconversion nanoparticles (UCNPs) were designed to detect ascorbic acid (AA). The blue emission of CSS was increased, ∼34 and ∼8 times higher than that of NaYF:2%Ho@NaYbF@NaYF (CSS (I)) and NaYbF@NaYF:20%Yb,2%Ho@ NaYF (CSS (II)), respectively. The dominant blue emission of CSS might be attributed to three aspects: (1) the protected NaYbF core for high near-infrared absorption, (2) the spatial separation of Yb and Ho preventing back energy transfer, and (3) their inert shell inhibiting surface quenching.
