Phage-ELISA for ultrasensitive detection of .

The M13 phage carries approximately 5 copies of the pIII protein, each of which is capable of displaying a single-chain variable fragment (scFv) that targets a specific antigen. This feature enables the M13 phage to be widely employed in the construction of scFv libraries, thereby facilitating the identification of antibodies with high specificity and affinity for target antigens. In this study, mice were immunized three times with (strain C50041) to induce diverse antibodies.

The molybdenum telluride (MoTe) monolayer can easily generate phase transitions between the 1H and 1T' phases due to a small energy barrier. However, distinguishing and identifying various defects during experiments is challenging.

Multiple Kinase Small Molecule Inhibitor Tinengotinib (TT-00420) Alone or With Chemotherapy Inhibit the Growth of SCLC.

Tinengotinib (TT-00420) is a novel, multi-targeted, and spectrally selective small-molecule kinase inhibitor that has shown significant inhibitory effects on certain solid tumors in preclinical studies. However, its role and mechanism of action in SCLC remain unclear.

APOC1 inhibit NKTCL doxorubicin sensitivity by promoting mitophagy.

NKTCL is a highly aggressive malignant tumor, especially prevalent in the southern regions of China. Although chemotherapy regimens based on ADM have achieved certain therapeutic effects in early treatment, the issue of ADM resistance severely limits the therapeutic efficacy and makes it difficult to improve patient survival rates. Our research results indicate that the expression level of APOC1 is closely related to the sensitivity of NKTCL cells to ADM.

Single-Injection Composite Tracer Achieves Intraoperative Dual-Tracing and Precise Localization of Sentinel Lymph Nodes.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.

Drosophila CG11700 may not affect male fecundity-lifespan tradeoff as previously reported.

Our recent investigations on the function of Drosophila CG11700 and CG32744 (Ubi-p5E) genes using CRISPR/Cas9 deletion technology could not repeat or confirm the results on CG11700 shown in our previous study which was based on P-element excision assay (Zhan et al. 2012). Here by CRISPR/Cas9 editing, we generated mutants of CG32744 with the whole gene body fully deleted from the genome, and truncated mutants of CG11700 with N-terminal 103 aa deleted out of its total 301 aa peptide sequence.

Isoleucine at position 137 of Hemagglutinin acts as a Mammalian adaptation marker of H9N2 Avian influenza virus.

The H9N2 subtype of avian influenza virus (AIV) is widely distributed among poultry and wild birds and is also a threat to humans. During AIV active surveillance in Liaoning province from 2015 to 2016, we identified ten H9N2 strains exhibiting different lethality to chick embryos. Two representative strains, A/chicken/China/LN07/2016 (CKLN/07) and A/chicken/China/LN17/2016 (CKLN/17), with similar genomic background but different chick embryo lethality, were chosen to evaluate the molecular basis for this difference.

Inhibition of aortic CX3CR1+ macrophages mitigates thoracic aortic aneurysm progression in Marfan syndrome in mice.

The pathogenesis of thoracic aortic aneurysm (TAA) in Marfan syndrome (MFS) is generally attributed to vascular smooth muscle cell (VSMC) pathologies. However, the role of immune cell-mediated inflammation remains elusive. Single-cell RNA sequencing identified a subset of CX3CR1+ macrophages mainly located in the intima in the aortic roots and ascending aortas of Fbn1C1041G/+ mice, further validated in MFS patients.

Endothelial STING-JAK1 interaction promotes tumor vasculature normalization and antitumor immunity.

Stimulator of interferon genes (STING) agonists have been developed and tested in clinical trials for their antitumor activity. However, the specific cell population(s) responsible for such STING activation-induced antitumor immunity have not been completely understood. In this study, we demonstrated that endothelial STING expression was critical for STING agonist-induced antitumor activity.

Continuous Near-Bed Movements of Microplastics in Open Channel Flows: Statistical Analysis.

The ubiquitous distribution of microplastics (MPs) in aquatic environments is linked to their transport in rivers and streams. However, the specific mechanism of bedload microplastic (MP) transport, notably their stochastic behaviors, remains an underexplored area. To investigate this, particle tracking velocimetry was employed to examine the continuous near-bed movements of four types of MPs under nine setups with different experimental conditions in a laboratory flume, with an emphasis on their streamwise transport.

A Glutamate Receptor-Like Gene AtGLR25 With Its Unusual Splice Variant Has a Role in Mediating Glutamate-Elicited Changes in Arabidopsis Root Architecture.

The occurrence of external L-glutamate at the Arabidopsis root tip triggers major changes in root architecture, but the mechanism of -L-Glu sensing is unknown. Members of the family of GLUTAMATE RECEPTOR-LIKE (GLR) proteins are known to act as amino acid-gated Ca-permeable channels and to have signalling roles in diverse plant processes. To investigate the possible role of GLRs in the root architectural response to L-Glu, we screened a collection of mutants with T-DNA insertions in each of the 20 AtGLR genes.
