Human leukocyte antigen (HLA) disparity between donors and recipients is a key determinant triggering intense alloreactivity, leading to a lethal complication, namely, acute graft-versus-host disease (aGVHD), after allogeneic transplantation. Moreover, aGVHD remains a cause of mortality after HLA-matched allogeneic transplantation. Protocols for HLA-haploidentical hematopoietic cell transplantation (haploHCT) have been established successfully and widely applied, further highlighting the urgency of performing panoramic screening of non-HLA variations correlated with aGVHD.

Combined allergic rhinitis and asthma syndrome (CARAS) is one of the common chronic airway inflammatory diseases in children. With the development of epigenetics, research on CARAS has gradually extended from protein levels to molecular levels, such as transcription and post-transcriptional regulation. N6-methyladenosine (m6A) methylation and ferroptosis have emerged as promising research hotspots in recent years, playing crucial roles in tumors, growth and development, and allergic diseases.

Despite its broad applications, fluorescence imaging technology often struggles in complex ecological and biological environments due to disadvantages of background autofluorescence and low quantum yield. This study introduced a near-infrared (NIR) multifunctional "off-on-off" isophorone-based fluorescent bio-probe, DHB, characterized by a high fluorescence quantum yield (10.

In this work, an interfacial engineering that combing the MoS and NiS together to form the MoS/NiS complex is proposed. The density functional theory (DFT) results reveals that the novel atomic-level heterojunction between MoS and NiS will build an internal electric field (IEF), which leads to an enhanced conductivity and valence change behavior of Ni atoms in MoS/NiS complex, resulting in a superior detection performance.

The absolute configurations of the five pairs of enantiomers were determined by the comparison of the calculated and experimental ECD spectra. Compounds 3a, 4a, 4b, and 12 were able to inhibit RSL3-induced ferroptosis.

We conducted a systematic literature review and analysis of studies published worldwide from January 2000 to July 2024 concerning the economic evaluation of RARP compared with laparoscopic radical prostatectomy (LRP) or open radical prostatectomy (ORP). A total of 16 papers were included.

In contrast, rat CRP (rCRP) is an atypical acute-phase protein that possesses unique features, such as a possible incapacity to trigger the complement system and markedly elevated baseline plasma concentrations. To facilitate studies on these unique characteristics, obtaining high-quality pure rCRP is essential.

Methods: Free latissimus dorsi myocutaneous flap on the cadaver was simulated dissected, and measured by Image-Pro Plus 6.0 to assess the feasibility of repairing giant head and neck defects.
Background: Stapokibart/CM310, a humanized monoclonal antibody targeting the interleukin-4 receptor α chain, has shown promising treatment benefits in patients with moderate-to-severe atopic dermatitis in previous phase II clinical trials.
Objective: We aimed to evaluate the long-term efficacy and safety of stapokibart in adults with moderate-to-severe atopic dermatitis.
Methods: Enrolled patients who previously completed parent trials of stapokibart received a subcutaneous stapokibart 600-mg loading dose, then 300 mg every 2 weeks up to 52 weeks.

Background: Osteoporosis is a common metabolic bone disorder induced by an imbalance between osteoclastic activity and osteogenic activity. During osteoporosis, bone mesenchymal stem cells (BMSCs) exhibit an increased ability to differentiate into adipocytes and a decreased ability to differentiate into osteoblasts, resulting in bone loss. Jumonji domain-containing 1C () has been demonstrated to suppress osteoclastogenesis.

Background: Schwannomas are uncommon tumors originating from Schwann cells, forming the neural sheath. They account for approximately 2%-6% of all mesenchymal tumors and are most commonly identified in peripheral nerve trunks, with rarity in the gastrointestinal tract. Among gastrointestinal locations, the stomach harbors the majority of nerve sheath tumors, while such occurrences in the sigmoid colon are exceptionally infrequent.

Surfactant deficiency is often seen in premature infants and in children and adults with respiratory distress syndrome. Mechanical stretch of alveolar type 2 epithelial (AT2) cells during lung expansion is the primary physiological factor that stimulates surfactant secretion; however, it is unclear whether there is a mechanosensor dedicated to this process.
