Dahuang-Gancao Decoction Ameliorates Testosterone-Induced Androgenetic Alopecia in Mice.

Ethnopharmacological Relevance: Dahuang-Gancao decoction (DGD) is a traditional Chinese medicinal formula that is recorded in the Synopsis of the Golden Chamber, and is widely used to treat damp-heat in the body. Since the pathological factors of androgenetic alopecia (AGA) also reflect damp-heat blockage, DGD has great potential for the treatment of AGA and has been used effectively in clinical practice.

Aim Of The Study: The aim of the study was to investigate whether external application of DGD could promote the activation and proliferation of hair follicle stem cells (HFSCs) and improve AGA through the Wnt/β-catenin pathway.

ZIF-67-derived NiCoO hollow nanocages coupled with g-CN nanosheets as Z-scheme photocatalysts for enhancing CO reduction.

Photocatalytic CO reduction technology plays a significant role in the energy and environmental sectors, highlighting the necessity for developing high-efficiency and stable catalysts. In this study, a novel photocatalyst, xNiCoO/CN (x = 1, 3, and 5 wt%), was synthesized by depositing zeolitic imidazolate framework-67 (ZIF-67)-derived nickel cobaltate (NiCoO) hollow nanocages onto porous graphitic carbon nitride (g-CN, CN) nanosheets for photocatalytic CO reduction. Under visible light irradiation, the resulting 3NiCoO/CN photocatalyst demonstrated exceptional CO yields of up to 2879.

Objective: Targeting CD47 for cancer immunotherapy has been studied in many clinical trials for the treatment of patients with advanced tumors. However, this therapeutic approach is often hampered by on-target side effects, physical barriers, and immunosuppressive tumor microenvironment (TME).

Methods: To improve therapeutic efficacy while minimizing toxicities, we engineered an oncolytic vaccinia virus (OVV) encoding an anti-CD47 nanobody (OVV-αCD47nb).

The compensatory enrichment of sphingosine-1-phosphate on HDL in FSGS enhances the protective function of glomerular endothelial cells compared to MCD.

Glomerular endothelial cells (GECs) are pivotal in developing glomerular sclerosis disorders. The advancement of focal segmental glomerulosclerosis (FSGS) is intimately tied to disruptions in lipid metabolism. Sphingosine-1-phosphate (S1P), a molecule transported by high-density lipoproteins (HDL), exhibits protective effects on vascular endothelial cells by upregulating phosphorylated endothelial nitric oxide synthase (p-eNOS) and enhancing nitric oxide (NO) production.

Prospective and retrospective analysis of whole slide images of sentinel and targeted lymph node frozen sections in breast cancer.

Different types of digital modalities are currently available for frozen section (FS) evaluation in surgical pathology practice. However, there are limited studies that demonstrate the potential of whole slide imaging (WSI) as a robust digital pathology option for FS FS diagnosis. In the current study, we compared the diagnostic accuracy achieved with WSI to that achieved with Light Microscopy (LM) for evaluating FSs of axillary sentinel lymph nodes (SLNs) and clipped lymph nodes (LNs) from breast cancer patients using two modalities.

Discovery of INCB159020, an Orally Bioavailable KRAS G12D Inhibitor.

The inhibition of mutant KRAS proteins has emerged as a promising approach for treating KRAS-driven cancers, as evidenced by the clinical success of KRAS G12C inhibitors. KRAS G12D, the most common mutant, promises significant expansion of the addressable patient population; however, the reduced nucleophilicity of aspartate compared to cysteine poses significant challenges in balancing sufficient potency with ADME properties to support oral exposure. Herein, we describe the discovery of KRAS G12D inhibitor (), which achieves oral exposure in nonhuman primate (NHP).

FcγR1-Expressing Cell Membrane-Coated Nanoparticle (FcγR1-CMNP) for T-Cell-Engaging Bispecific Nanoantibody Construction.

T-cell-engaging bispecific antibodies (BiTEs), which can simultaneously bind to antigens on tumor cells and T cells, show good potential in cancer immunotherapy. A practical and feasible approach for emulating BiTEs involves immobilizing two types of monoclonal antibodies (mAbs) onto a single nanoparticle; however, this approach involves complex immobilization processes and chemical reactions. To overcome these challenges, we achieved gentle antibody immobilization through receptor-ligand interactions by constructing a mAb delivery system known as Fcγ receptor 1 (FcγR1)-expressing cell membrane-coated nanoparticles (abbreviated as FcγR1-CMNPs).

Evaluation of the Efficacy of the Vaccine Production Process in Removing Residual Host Cell DNA from the Vero Cell Rabies Vaccine.

Background: The Vero cell rabies vaccine is currently the most widely used human rabies vaccine. However, owing to the presence of residual host cell DNA (HCD) in the final product and the potential tumorigenicity of the DNA of high-passage Vero cells, the WHO not only sets a limit on the number of times cells used in production can be passaged, but also imposes strict requirements on the amount of residual HCD in the final vaccine product.

Objectives: To systematically reduce the HCD level in the final vaccine product, multiple purification steps are included in the vaccine production process.

A Bait-and-Hook Hydrogel for Net Tumor Cells to Enhance Chemotherapy and Mitigate Metastatic Dissemination.

: Lung cancer is an aggressive disease with rapid progression and a high rate of metastasis, leading to a significantly poor prognosis for many patients. While chemotherapy continues to serve as a cornerstone treatment for a large proportion of lung cancer patients, expanding preclinical and clinical evidence indicates that chemotherapy may promote tumor metastasis and cause side effects. : We develop an injectable bait-and-hook hydrogel (BH-gel) for targeted tumor cell eradication, which embedded doxorubicin liposomes as cytotoxic agents and CXCL12 as a chemoattractant to capture and kill tumor cells.
