Blinatumomab has shown to improve survival outcomes in B-cell acute lymphoblastic leukemia (B-ALL) patients with measurable residual disease (MRD) detected by multiparametric flow cytometry (MFC). However, data on blinatumomab clearing MRD with high sensitivity remain scarce. This study evaluates the effectiveness of blinatumomab in eradicating low levels of MRD, as detected by droplet digital PCR (ddPCR) but undetectable by MFC, in children with B-ALL.

Objectives: This study aims to investigate the use of sodium iodide (NaI), dimethyl sulfoxide (DMSO), ethyl alcohol, and ethyl acetate as cone-beam CT (CBCT) contrast agents for diagnosing cracked teeth. The optimal delay time for detecting the number of crack lines beyond the dentino-enamel junction (Nd), the number of cracks extending from the occlusal surface to the pulp cavity (Np), and the depth of the crack lines was explored.

Methods: 14 human extracted cracked teeth were collected, 12 were used for enhanced scanning, and 2 were used for exploring the characteristic of crack lines.

Background: The use of mesenchymal stem cells (MSCs) has recently emerged as a promising new therapeutic strategy for many diseases including perianal fistulizing Crohn's disease (CD). Whether hUC-MSCs can promote the healing of luminal ulcer in CD has not been studied so far.

Methods: The model of TNBS-induced colitis in rats was used to confirm the efficacy of hUC-MSCs in the treatment of CD.

Introduction: The purpose of this study was to explore the mechanism of vertical root fracture (VRF) using three-dimensional finite element models (FEMs).

Methods: An endodontically treated mandibular first molar with a subtle VRF was collected and scanned with cone beam CT (CBCT). Three finite element analysis models were created: Model 1 had the actual endodontically treated root canal size; Model 2 had the same root canal size as the contralateral homonymous tooth; and Model 3 had the root canal size expanded by 1 mm based on Model 1.

Background: Gastroesophageal reflux symptom (GERS) occur frequently in obese patients. Although some surgeons avoid laparoscopic sleeve gastrectomy (LSG) in these patients for fear of postoperative exacerbation of GERS, this notion is not supported by sufficient medical evidence.

Objectives: This prospective study aimed to evaluate the impact of LSG on GERS.

Objectives: Evaluating the diagnostic efficiency of deep learning models to diagnose vertical root fracture in vivo on cone-beam CT (CBCT) images.

Materials And Methods: The CBCT images of 276 teeth (138 VRF teeth and 138 non-VRF teeth) were enrolled and analyzed retrospectively. The diagnostic results of these teeth were confirmed by two chief radiologists.

Objectives: To explore the feasibility of using sodium iodide (NaI)+dimethyl sulfoxide (DMSO)+ethyl alcohol+ethyl acetate as a cone-beam CT (CBCT) contrast agent in the diagnosis of vertical root fracture (VRF).

Methods: 21 endodontically treated VRF teeth of 21 patients were collected in this study. All these 21 teeth were confirmed subtle fracture lines under transillumination, the number and position of fracture lines were recorded.

Introduction: Purpura fulminans (PF) is a hematological emergency that can be caused by severe congenital protein C (PC) deficiency. It has been rarely reported in the Chinese population. We aimed to characterize the clinical and genetic features of Chinese pediatric patients with severe congenital PC deficiency who first presented with PF.

Hepatocellular carcinoma (HCC) is the leading cause of cancer death in men before the age of 60 years in China. Interleukin (IL)36 played important roles in antitumor immune responses, but its role in HCC is still unknown. We aimed to explore the correlation between IL36 and prognosis of HCC patients.

It has been reported that overexpression of the CRLF2 gene is associated with poor outcomes in pediatric B cell acute lymphoblastic leukemia (B-ALL), but the incidence rates, clinical characteristics and outcomes of CRLF2 gene overexpression in pediatric T cell ALL (T-ALL) have not been systematically analyzed. In this study, CRLF2 mRNA expression levels and clinical and laboratory parameters in 63 pediatric T-ALL patients were detected at the Children's Hospital of Chongqing Medical University and Children's Hospital of Xianyang between February 2015 and June 2018. The patients were treated according to the modified St.

Objective: To investigate the correlation of E-cadherin expression level with the clinical characterastics in children with acute leukemia (AL), and to explore the possible regulatory mechanism.

Methods: Real-time quantitative RT-PCR was applied to detect the expression level of E-cadherin in bone marrow samples from 135 child patients diagnosed as AL, and its relevance with clinical indicators was statistically analyzed. The expression levels of E-cadherin, β-catenin, and Akt/p-Akt were detected by using Western blot.

Dye-sensitized solar cells (DSSCs) are currently the most widely developed low-cost photovoltaic devices. A series of D-A-π-A metal-free organic dyes based on IQ1 were designed and theoretically characterized by introducing different auxiliary acceptors. The results show that the introduction of auxiliary heterocyclic acceptors could effectively tune the photoelectronic properties.

Objective: To study the expression of β-integrin family members in children with T-cell acute lymphoblastic leukemia (T-ALL) and their significance.

Methods: Quantitative real-time PCR analyses were performed to assess the expression levels of β-integrin family members in bone marrow samples from 22 children with newly-diagnosed T-ALL and 21 controls (16 children with non-malignant hematologic disease and 5 healthy donors with bone marrow transplantation). Jurkat cells were treated with integrin inhibitor arginine-glycine-aspartate (Arg-Gly-Asp, RGD) peptide.

Unlabelled: Frightening music can rapidly arouse emotions in listeners that mimic those from actual life-threatening experiences. However, studies of the underlying mechanism for perceiving danger created by music are limited.

Methods: We investigated monoamine receptor changes induced by frightening music using (11)C-N-methyl-spiperone ((11)C-NMSP) PET.

Membrane distillation is a thermally driven membrane process for seawater desalination and purification at moderate temperatures and pressures. A hydrophobic micro-porous membrane is used in this process, which separates hot and cold water, allowing water vapor to pass through; while restricting the movement of liquid water, due to its hydrophobic nature. This paper provides an experimental investigation of heat and mass transfer in tubular membrane module for water desalination.

Background: Molecular therapies that target genetic abnormalities in leukemic cells and their affected signaling pathways have been emerging in pediatric acute lymphoblastic leukemia (ALL). Glycogen synthase kinase-3β (GSK-3β) has recently been found to positively regulate the activity of nuclear factor-κB (NF-κB). Here, we investigated the relationship between GSK-3β inhibition and NF-κB in apoptosis of pediatric primary leukemia cells obtained from 39 newly diagnosed ALL children in China.
