Published: March 2021

Electrospun carbon nanofibers (CNFs), which were modified with hydroxyapatite, were fabricated to be used as a substrate for bone cell proliferation. The CNFs were derived from electrospun polyacrylonitrile (PAN) nanofibers after two steps of heat treatment: stabilization and carbonization. Carbon nanofibrous (CNF)/hydroxyapatite (HA) nanocomposites were prepared by two different methods; one of them being modification during electrospinning (CNF-8HA) and the second method being hydrothermal modification after carbonization (CNF-8HA; hydrothermally) to be used as a platform for bone tissue engineering. The biological investigations were performed using in-vitro cell counting, WST cell viability and cell morphology after three and seven days. L929 mouse fibroblasts were found to be more viable on the hydrothermally-modified CNF scaffolds than on the unmodified CNF scaffolds. The biological characterizations of the synthesized CNF/HA nanofibrous composites indicated higher capability of bone regeneration.

Objectives: Acute T-cell lymphoblastic leukemia (T-ALL) is a severe hematologic malignancy with limited treatment options and poor long-term survival. This study explores the role of IKZF1 in regulating BCL-2 expression in T-ALL.

Methods: CUT&Tag and CUT&Run assays were employed to assess IKZF1 binding to the BCL-2 promoter.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear.

Background: Non-Hodgkin lymphoma (NHL) is the seventh most common cancer among Asian, Native Hawaiian and Pacific Islanders (ANHPIs), yet the risk of death in specific ANHPI subgroups in the US is unknown.

Methods: We used Surveillance, Epidemiology, and End Results data to investigate relative survival and the risk of death among NHL patients in ANHPI subgroups. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals (CI), comparing ANHPI subgroups to non-Hispanic White (NHW) NHL patients for all-cause death and NHL-specific death.

In recent years, the use of cationic peptides as alternative drugs with anticancer activity has received attention. In this study, the targeted release of curcumin (Cur) and CM11 peptide alone and together against hepatocellular carcinoma (HCC) was evaluated using chitosan nanoparticles (CS NPs) coated with Pres1 that target the SB3 antigen of HCC cells (PreS1-Cur-CM11-CS NPs). SB3 protein is the specific antigen of HCC and the PreS1 peptide is a part of the hepatitis B antigen, which can specifically bind to the SB3 protein.

Background: The purpose of this study was to investigate the safety and efficacy of left thoracic approach (LTA) and right thoracic approach (RTA) in patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant immunochemotherapy (NICT).

Methods: This study included 83 ESCC patients who underwent right transthoracic esophagectomy ( = 61) and left transthoracic esophagectomy ( = 22) after NICT in our hospital from October 2019 to September 2023. The data of these patients were retrospectively analyzed.
