Expert consensus on pulpotomy in the management of mature permanent teeth with pulpitis.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth.

Characterization of stem cell landscape and identification of stemness-relevant prognostic gene signature to aid immunotherapy in breast cancer.

A common digestive system cancer with a dismal prognosis and a high death rate globally is breast cancer (BRCA). BRCA recurrence, metastasis, and medication resistance are all significantly impacted by cancer stem cells (CSCs). However, the relationship between CSCs and the tumor microenvironment in BRCA individuals remains unknown, and this information is critically needed.

CD300E macrophages facilitate liver regeneration after splenectomy in decompensated cirrhotic patients.

Liver cirrhosis is prognostically associated with poor life expectancy owing to subsequent liver failure. Thus, understanding liver regeneration processes during cirrhotic injury is highly important. This study explored the role of macrophage heterogeneity in liver regeneration following splenectomy.

Pharmacokinetics of cisplatin in the systemic versus hyperthermic intrathoracic or intraperitoneal chemotherapy.

Objective: To compare the pharmacokinetics and adverse effects of cisplatin administered via intravenous infusion for systemic chemotherapy (SC) versus injection into the perfusate during hyperthermic intrathoracic chemotherapy (HITHOC) or hyperthermic intraperitoneal chemotherapy (HIPEC).

Methods: Total 60 patients who received SC, HITHOC, or HIPEC in the Department of Oncology, Tangdu Hospital, were enrolled into this study. After administering same dose of cisplatin (40 mg) via either intravenous infusion (SC group) or injection into the perfusate during the HITHOC or HIPEC procedure, concentration of cisplatin in the plasma as well as in the hyperthermic perfusate at various time points was quantified by HPLC analysis.

Preimplantation genetic testing for structural rearrangements by genome-wide SNP genotyping and haplotype analysis: a prospective multicenter clinical study.

Background: Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) has been widely utilized to select euploid embryos in patients carrying balanced chromosomal rearrangements (BCRs) by chromosome copy number analysis. However, reliable and extensively validated PGT-SR methods for selecting embryos without BCRs in large-cohort studies are lacking.

Methods: In this prospective, multicenter, cohort study, carriers with BCRs undergoing PGT-SR were recruited across 12 academic fertility centers within China.

Exploring the impact of blood and bone debris at the implant-abutment interface on peak removal torque: Bridging clinical observations with laboratory evidence.

Statement Of Problem: Three months after implant placement, difficulty was encountered in unscrewing the healing abutment within the normal torque range (<35 Ncm), resulting in the removal of the implant. Despite all attempts, the implant could not then be separated from the healing abutment. Retrospective analysis of intraoperative photographs revealed the presence of blood or bone debris within the implant before the healing abutment was placed; this was considered to be the likely cause of this phenomenon.

Chiral iodine-catalyzed asymmetric oxyamination of unactivated olefins.

In this paper, chiral aryl iodides were used for the first time to catalyze the formation of C-O and C-N bonds of inactive olefins to obtain optically active aminolactone derivatives. The reaction is compatible with various substituted alkenyl carboxylic acid substrates. This method usually shows high activity and enantioselectivity, with a yield of up to 83% and an ee of up to 99%.

Carvacrol alleviates LPS-induced myocardial dysfunction by inhibiting the TLR4/MyD88/NF-κB and NLRP3 inflammasome in cardiomyocytes.

Background: Sepsis-induced myocardial dysfunction (SIMD) may contribute to the poor prognosis of septic patients. Carvacrol (2-methyl-5-isopropyl phenol), a phenolic monoterpene compound extracted from various aromatic plants and fragrance essential oils, has multiple beneficial effects such as antibacterial, anti-inflammatory, and antioxidant properties. These attributes make it potentially useful for treating many diseases.

Anti irradiation nanoparticles shelter immune organ from radio-damage via preventing the IKK/IκB/NF-κB activation.

Background: Normal tissue and immune organ protection are critical parts of the tumor radiation therapy process. Radiation-induced immune organ damage (RIOD) causes several side reactions by increasing oxidative stress and inflammatory responses, resulting in unsatisfactory curability in tumor radiation therapy. The aim of this study was to develop a novel and efficient anti irradiation nanoparticle and explore its mechanism of protecting splenic tissue from radiation in mice.

GDF15 attenuates sepsis-induced myocardial dysfunction by inhibiting cardiomyocytes ferroptosis via the SOCS1/GPX4 signaling pathway.

Sepsis is a systemic inflammatory response syndrome triggered by infection, presenting with symptoms such as fever, increased heart rate, and low blood pressure. In severe cases, it can lead to multiple organ dysfunction, posing a life-threatening risk. Sepsis-induced cardiomyopathy (SIC) is a critical factor in the poor prognosis of septic patients, leading to myocardial dysfunction characterized by cell death, inflammation, and diminished cardiac function.
