Japanese encephalitis caused by Japanese encephalitis virus (JEV) infection leads to the central nervous system disorder in human and swine. Viruses utilize the host protein synthesis mechanisms to efficiently translate their RNAs. Herein, we demonstrated that the host transcription factor SOX10 downregulated an RNA-binding protein heterogeneous nuclear ribonucleoprotein H (HNRNPH1) during JEV infection.

Benefiting from the high electrical conductivity of the carbon matrix and the strong interaction as well as the efficient electrocatalytic activity of CoP with iodine species, the host achieved rapid iodine conversion while effectively suppressing the formation of polyiodides and zinc dendrites.

PEDV starts its life cycle by binding to the receptors of host cells and adsorbing onto the cellular surfaces. However, it is still unknown how PEDV adsorbs onto the surface of host cells and the mechanism beneath the interplay of host cell transmembrane protein with PEDV proteins.

Previous studies have shown that KBs protect against respiratory diseases; however, there is no evidence of a genetic link. To avoid biases existing in traditional observational studies, a two-sample Mendelian randomization (MR) analysis was carried out to investigate genetic causation and novel therapeutic uses for KBs.

Neutralizing antibodies (nAbs) play a crucial role in virology, antibody drug development, and vaccine research. In this study, we investigated the synergistic effect of two hepatitis E virus (HEV) nAbs, 8H3, and 8C11, which have exhibited enhanced neutralizing activity in a rhesus monkey model. We presented crystal structures of 8H3 Fab alone and a triple complex of 8C11 Fab and 8H3 Fab simultaneously binding to the HEV E2s protein (8C11:E2s:8H3).

Although palivizumab and nirsevimab, neutralizing antibodies (nAbs) targeting the RSV F protein, have been used for prophylaxis, their limitations underscore the need for more effective alternatives. Herein, we present a potent and broad nAb, named 5B11, which exhibits nanogram level of unbiased neutralizing activities against both RSV-A and -B subgroups.

In the present study, we report the specific neutralizing antibodies 13H7 and 9G11, which target the N-terminal domain (NTD) and receptor-binding domain (RBD) of the SARS-CoV-2, respectively. The comparative analysis observed that 13H7 not only neutralizes early variants of concern (VOCs) but also exhibits neutralizing activity against the Omicron sublineage, including BA.

Compared to single-label text classification, MLTC is more challenging due to its vast collection of labels which include extracting local semantic information, learning label correlations, and solving label data imbalance problems. This paper proposes a model of Label Attention and Correlation Networks (LACN) to address the challenges of classifying multi-label text and enhance classification performance.

The diffusion phenomenon that exhibits intrinsic similarities is pervasive in cryptography and natural systems, evident in liquid diffusion, epidemic spread, animal migration, and encryption techniques. In cryptography, bytes are systematically diffused in a sequential manner to encrypt the value of each byte in the plaintext in a linear fashion. In contrast, within an epidemic spreading model, the diffusion process can be represented within a complex, multilayered network, encompassing layers such as familial and social transmission dynamics.

We evaluated the effects of three common ventilation modes on postoperative pulmonary complications (PPCs) among intermediate- to high-risk patients undergoing abdominal surgery.
Methods: This randomized clinical trial enrolled adult patients at intermediate or high risk of PPCs who were scheduled for abdominal surgery.
Unlabelled: Hepatitis B virus (HBV) infection is a significant global health concern due to elevated immunosuppressive viral antigen levels, the host immune system's inability to manage HBV, and the liver's immunosuppressive conditions. While immunotherapies utilizing broadly reactive HBV neutralizing antibodies present potential due to their antiviral capabilities and Fc-dependent vaccinal effects, they necessitate prolonged and frequent dosing to achieve optimal therapeutic outcomes. Toll-like receptor 7/8 (TLR7/8) agonists have been demonstrated promise for the cure of chronic hepatitis B, but their systemic use often leads to intense side effects.

An increasing number of pathogenic bacteria that cause human diseases have been shown to express polysaccharides containing a bacterial nonulosonic acid called 5,7-di--acetyllegionaminic acid (Leg5,7Ac). To investigate the immune recognition of Leg5,7Ac, which is critical for the fight against bacterial infections, a highly effective chemoenzymatic synthon strategy was applied to construct a library of α2-3/6-linked Leg5,7Ac-glycans via their diazido-derivatives (Leg5,7diN-glycans) formed by efficient one-pot three-enzyme (OP3E) synthetic systems from a diazido-derivative of a six-carbon monosaccharide precursor.
