Expert consensus on classification and diagnosis of congenital orofacial cleft.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines.

Improved Efficacy of Triple-Negative Breast Cancer Immunotherapy via Hydrogel-Based Co-Delivery of CAR-T Cells and Mitophagy Agonist.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

GnIH secreted by green light exposure, regulates bone mass through the activation of Gpr147.

Reproductive hormones associated with the hypothalamic-pituitary-gonadal (HPG) axis are closely linked to bone homeostasis. In this study, we demonstrate that Gonadotropin inhibitory hormone (GnIH, one of the key reproductive hormones upstream of the HPG axis) plays an indispensable role in regulating bone homeostasis and maintaining bone mass. We find that deficiency of GnIH or its receptor Gpr147 leads to a significant reduction in bone mineral density (BMD) in mice primarily by enhancement of osteoclast activation in vivo and in vitro.

Homotypic membrane-camouflaged camptothecin nanorods combining photothermal and chemotherapy for synergistic antitumor therapy.

Chemotherapy hardly achieves satisfactory therapeutic efficacy owing to the widely occurred adverse effects and drug tolerance, and the extensively investigated delivery systems suffer from complicated synthesis, low drug loading and less efficient tumor accumulation. Herein, we developed rod-shape nanocrystals to address challenges in the circulation stability, tumor targeting and therapeutic efficacy of camptothecin (CPT), a mainstay of treatments for various cancers. CPT nanorods (CNR) were coated with polydopamine (PDA) to achieve combinational chemo- and photothermal therapies (PTT) and then wrapped with cell membrane (CM) from homotypic tumor cells to obtain CNR@PDA-CM.

Biophysiochemically favorable, antithrombotic and pro-endothelial coordination compound nanocoating of copper (II) with protocatechuic acid & nattokinase on flow-diverting stents.

Neurovascular flow-diverting stents (FDSs) are revolutionizing the paradigm for treatment of intracranial aneurysms, but they still face great challenges like post- implantation acute thrombosis and delayed reendothelialization. Surface modification is of crucial relevance in addressing such key issues. In this study, we fabricated an ultrathin nanocoating out of copper (II) together with protocatechuic acid (PCA) and nattokinase (NK) bioactive molecules on NiTi FDSs via a coordination chemistry approach, with favorable biophysiochemical interactions, to fulfill this goal.

Biochar reduces plasmid-mediated antibiotic resistance gene transfer in earthworm ecological filters for rural sewage treatment.

Regulating astrocyte phenotype by Lcn2 inhibition toward ischemic stroke therapy.

Astrocytes can be reacted to "reactive astrocytes" after ischemia-reperfusion injury, in which A1 phenotype causes neuronal and oligodendrocyte death, whereas the A2 phenotype exerts neuroprotective effects, thus regulating reactive astrocyte to A2 type is a potential target for stroke therapy. Lcn2 level is highly associated with the phenotypic polarization of astrocytes. We found that silencing the Lcn2 gene by adeno-associated virus (AAV)-Lcn2 shRNA adenovirus resulted in a dramatic decrease in A1-type astrocytes and increase in A2 astrocytes in MCAO mice.

A Vacuum Ultraviolet (UV) Photoreactor-Based Flow Droplet Digestion for Determination of Arsenic and Mercury in Blood by Atomic Fluorescence Spectrometry.

It is still challenging to perform a high-throughput digestion on limited amounts of sample prior to elemental analysis by atomic spectrometry. Herein, a photochemical reactor consisting of a quartz tube inserted into a low-pressure mercury lamp was used to fabricate a flow droplet photodigestion (FD-PD) device for the high-throughput digestion of small amounts of samples. A mixture containing 20 μL of blood sample, 20 μL of HO, and 10 μL of HNO was pumped and passed through the reactor before its online analysis by hydride generation atomic fluorescence spectrometry (HG-AFS).
