Recently, piezoelectric and photocatalytic processes have shown excellent synergistic effect addressing environmental remediation challenges. Herein, a nanoflower-like Mo vacancy-modulated MoS (V-MoS) piezo-photocatalyst with different V densities has been successfully synthesized using a one-step hydrothermal method. The high V density (12%) facilitates the enhancement of the photocatalytic activity but compromises its structural stability, resulting in unsatisfactory piezoelectric activity.

Here, we develop an ion-selective polymeraldine salt (PANI-Cl; PANI = polyaniline) modulated TiCT MXene electrode as a mediator for electrochemical capture of fluoride ion (F) from groundwater. The single-stage configuration equipped with PANI-Cl/TiCT electrode as anode and activated carbon as cathode exhibits an ultrafast removal rate of 4.

However, their broad application is hindered by the scarcity of tumor-associated antigens on tumor cell surfaces. Previous investigations unveiled the unique capacity of pH-low insertion peptide (pHLIP) to anchor to plasma membranes under acidic conditions.

Endometriosis (EMS) is known to be closely associated with inflammation. We evaluate the possible mechanism linking the PI3K/AKT signaling pathway with pyroptosis and inflammation in EMS. We collected 30 patients undergoing laparoscopic for endometriosis as the EMS group and those undergoing surgery for uterine fibroids as the control group, from whom we collected serum, normal endometrium, eutopic endometrium and ectopic endometrium.

Herein, a MoS /MIL-53(Fe) photocatalyst/activator with the S-scheme heterojunction structure is designed and the charge migration behavior is modulated by the internal electric field (IEF). The IEF intensity is enhanced to 40 mV by modulating band bending potential and the depletion layer length of MoS .

Aiming at improving freshwater production capability and ensuring its quality, an interfacial charge-modulated MoS/TiCT-modified carbon fiber (CF/MoS/TiCT) penetrating electrode is designed. To maximize the desalination and degradation efficiencies of CF/MoS/TiCT, a photocatalytic component is introduced into the membrane capacitive deionization (PMCDI) device.

The current methods for detecting circulating tumor cells (CTCs) suffer from several drawbacks. We report a novel method that is based on a chimeric virus probe and can detect CTCs with extremely high specificity and sensitivity. Moreover, it exclusively detects live CTCs, and its detection efficacy is not impacted by the variation of epithelial cell adhesion molecule (EpCAM) expression.

Endometriosis (EM), a benign aseptic inflammatory disease, is associated with the presence of endometrial foci. Pain, one of its typical symptoms, has been reported as a constant stressor, but the etiology and pathogenesis of EM-associated pain are unclear. In the present study, eutopic and ectopic endometrium samples from women with EM (n=50) and normal endometrium samples from control subjects (n=20) were collected.

Coronavirus Disease 2019 (COVID-19) remains a global health crisis, despite the development and success of vaccines in certain countries. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, uses its spike protein to bind to the human cell surface receptor angiotensin-converting enzyme 2 (ACE2), which allows the virus to enter the human body. Using our unique cell screening technology, we identified two ACE2-binding peptoid compounds and developed dimeric derivatives (ACE2P1D1 and ACE2P2D1) that effectively blocked spike protein-ACE2 interaction, resulting in the inhibition of SARS-CoV-2 pseudovirus entry into human cells.

The receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 spike (S) protein plays a central role in mediating the first step of virus infection to cause disease: virus binding to angiotensin-converting enzyme 2 (ACE2) receptors on human host cells. Therefore, S/RBD is an ideal target for blocking and neutralization therapies to prevent and treat coronavirus disease 2019 (COVID-19). Using a target-based selection approach, we developed oligonucleotide aptamers containing a conserved sequence motif that specifically targets S/RBD.

Virus neutralization assay is principally conducted by measuring the ability of the antibodies in patient sera to prevent the infection of susceptible cells by the virus. As SARS-CoV-2 is classified as a risk group 3 pathogen, neutralization assay using a live virus needs to be handled in a biosafety level 3 laboratory. To overcome this limitation, pseudotyped viruses have been developed as an alternative for the live SARS-CoV-2.

One of the major hurdles for cancer immunotherapy is the host's innate antiviral defense mechanisms. They include innate immune cells, such as natural killer (NK) cells and macrophages, which can be recruited within hours to the site of injection to clear the introduced oncolytic viruses. Here, we report a strategy to redirect these infiltrating innate immune cells to attack tumor cells instead by arming herpes simplex virus (HSV)-derived oncolytic viruses with secreted chimeric molecules that can engage these innate immune cells with tumor cells to kill the latter.

An accurate, easy-to-apply, and inexpensive hearing screening method is needed to detect hearing loss in community-dwelling elderly people, intervene early and reduce the negative consequences and burden of untreated hearing loss on individuals, families and society. However, available hearing screening tools do not adequately meet the need for large-scale geriatric hearing detection due to several barriers, including time, personnel training and equipment costs.

It is generally believed that natural killer cells are the key component of the innate immune system in determining tumor metastatic potential in xenograft models. However, recent studies suggest that macrophages may play an important role, as resident macrophages can eliminate the invading tumor cells if they do not express adequate levels of the CD47 molecule.

However, for treating solid tumors, there is a need for improving the ability of the adoptively transferred T cells to home to tumor sites. We explored the possibility of using an oncolytic virus derived from HSV-2, which can actively pull T effector cells to the site of infection, as a local attractant for migration of adoptively transferred T cells.
