Coal is a typical fossil fuel and it is also a natural carbon material, therefore, converting it to functional carbon materials is an effective way to enhance the economic advantages of coal. Here, ultrathin N-doped carbon nanosheets were prepared from low-cost coal via a handy and green molten-salt method, which shown excellent performance for lithium-ion batteries (LIBs). The formation mechanism of ultrathin nanosheets was studied in detail.

Combination administration is becoming a popular strategy in current cancer immunotherapy to enhance tumor response to ICIs. Recently, a peptide drug, a protein-protein interaction inhibitor (PPI), that disrupts the β-catenin/Bcl9 interaction in the tumoral Wnt/β-catenin pathway has become a promising candidate drug for immune enhancement and tumor growth inhibition. However, the peptide usually suffers from poor cell membrane permeability and proteolytic degradation, limiting its adequate accumulation in tumors and ultimately leading to side effects.

Article Synopsis
  • Ex vivo lung perfusion (EVLP) is a testing method for lungs that is usually expensive and requires lab animals, but a new method using sheep lungs from an abattoir has been developed to reduce costs.
  • In the study, sheep lungs were flushed and perfused under controlled conditions, and various measurements were recorded, showing stability in oxygen levels and pressure during perfusion.
  • The results indicate that abattoir-sourced sheep lungs can be perfused effectively, providing a more accessible and cost-effective option for lung research, which could lead to more discoveries in treating lung diseases.

Introduction: Laparoscopic splenectomy and esophagogastric devascularization (LSED) is becoming increasingly popular in the treatment of esophageal-fundic variceal bleeding with portal hypertension (PHT) in China, and its high safety and minimal trauma have been proven. Fast-track (FT) surgery improves patient recovery and decreases postoperative complications.

Aim: To determine whether LSED with fast-track principles can provide better outcomes than traditional treatment for patients with PHT.

RIOK2 is an atypical kinase implicated in multiple human cancers. Although recent studies establish the role of RIOK2 in ribosome maturation and cell cycle progression, its biological functions remain poorly elucidated, hindering the potential to explore RIOK2 as a therapeutic target. Here, we report the discovery of , the most potent and selective RIOK2 inhibitor reported so far.

Tropomyosin receptor kinase (TRK) secondary mutations mediating acquired resistance, especially at the solvent-front (SF) and the DFG motif, represent an unmet clinical need. Small-molecule macrocyclic kinase inhibitors have displayed significant advantages in overcoming clinical resistance driven by kinase mutations; however, all reported small-molecule macrocyclic TRK inhibitors are all type I inhibitors and are therefore much more sensitive to SF than xDFG mutations. Novel therapeutics for patients with xDFG resistance mutations are urgently needed.

Aberrantly activated Janus kinase 3 (JAK3) has been constantly detected in various immune disorders and hematopoietic cancers, suggesting its potential of being an attractive therapeutic target for these indications. Clinical benefits of drugs selectively targeting JAK3 versus pan-JAK inhibitors remain unclear. In this study, we report the design and synthesis of a new series of JAK3 covalent inhibitors with a pyrido[2,3-d]pyrimidin-7-one scaffold.

Chirality in biomolecules is ubiquitous in our world, but oral nanomedicines constructed from chiral peptides are extremely rare, principally because of the immature nanofabrication and inadequate bioavailability of chiral nanostructures. To realize the oral administration of chiral peptides and break through their forbidden zone in intracellular space, a chiral-peptide supramolecular (DPAICP) camouflaging with the membrane from milk-derived extracellular vesicles (ME) was developed herein through an aqueous-based growth method of chiral peptide Au(I) infinite covalent polymer (DPAICP) involving in organothiol D-peptides and Au, and a feasible camouflage technology using ME. DPAICP@ME possessed favorable pharmaceutical properties to remain stable during the gastrointestinal absorption and blood circulation, and showed the satisfactory tumor accumulation through oral medication.

Background: The anti-tumor activity and acceptable tolerability of pyrotinib plus chemotherapy have been demonstrated in phase III trials in human epidermal growth factor receptor 2-positive metastatic breast cancer (BC). In this study, we assessed the efficacy and safety of neoadjuvant pyrotinib plus trastuzumab and albumin-bound paclitaxel in women with human epidermal growth factor receptor 2-positive early or locally advanced BC.

Methods: In this single-arm exploratory phase II trial, patients with untreated human epidermal growth factor receptor 2-positive BC (stage IIA-IIIC) received pyrotinib 400 mg once daily, trastuzumab 4 mg/kg loading dose, followed by 2 mg/kg once a week, and albumin-bound paclitaxel 125 mg/m once a week for four 21-day cycles before surgery.

Percutaneous vertebral augmentation (PVA) and percutaneous cement discoplasty (PCD) are two relatively new minimally invasive surgeries for symptomatic Schmorl's reported in recent decade. However, the clinical evidence for the effectiveness of these two surgeries is insufficient. The purpose of this study was to compare the biomechanical benefits and risks of the two surgeries in order to analyze their biomechanical differences and effectiveness.
