Relapsed or refractory T-cell acute lymphoblastic leukemia/lymphoma (r/r T-ALL/LBL) are frequently aggressive and associated with unfavorable prognoses. Pan-targeted Chimeric Antigen Receptor (CAR) T-cell therapy have shown promising results in clinical trials. In recent years, CD7 CAR T-cell and CD5 CAR T-cell demonstrate effectiveness in treating r/r T-ALL/LBL patients with bone marrow infiltration.

Background: Epidermal growth factor receptor (EGFR) is a key protein in cellular signaling that is overexpressed in many human cancers, making it a compelling therapeutic target. On-target severe skin toxicity has limited its clinical application. Dual-targeting therapy represents a novel approach to overcome the challenges of EGFR-targeted therapies.

Background: To investigate changes in pulmonary artery pressure (PAP), blood indices, and myocardial microcirculation in rats returning from high altitude (HA) to moderate altitude (MA).

Methods: Forty 4-week-old male Sprague-Dawley rats were randomly divided into four groups with ten rats in each group. One group was transported to the MA area (MA-group), and the other three groups were transported to HA (HA-group-A, HA-group-B, and HA-group-C).

Mild cognitive impairment (MCI) is a precursor stage of dementia characterized by mild cognitive decline in one or more cognitive domains, without meeting the criteria for dementia. MCI is considered a prodromal form of Alzheimer's disease (AD). Early identification of MCI is crucial for both intervention and prevention of AD.

Article Synopsis
  • Severe cytokine release syndrome (sCRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) hinder the use of CAR T-cell therapy, prompting researchers to develop a new CAR (ssCART-19) that incorporates shRNA to target the IL-6 gene.
  • In a study involving 87 patients with relapsed/refractory B-cell acute lymphoblastic leukemia, ssCART-19 demonstrated significantly lower rates of grade ≥3 CRS (14.89%) and ICANS (4.26%) compared to conventional CAR T-cells (cCART-19) which had rates of 37.5% and 15%, respectively.
  • Overall response rates and survival metrics were comparable

Objective: To create a deep-learning automatic segmentation model for esophageal cancer (EC), metastatic lymph nodes (MLNs) and their adjacent structures using the UperNet Swin network and computed tomography angiography (CTA) images and to improve the effectiveness and precision of EC automatic segmentation and TN stage diagnosis.

Methods: Attention U-Net, UperNet Swin, UNet++ and UNet were used to train the EC segmentation model to automatically segment the EC, esophagus, pericardium, aorta and MLN from CTA images of 182 patients with postoperative pathologically proven EC. The Dice similarity coefficient (DSC), sensitivity, and positive predictive value (PPV) were used to assess their segmentation effectiveness.

The ankyrin (ANK) SOCS box (ASB) family, encompassing ASB1-18, is the largest group of substrate receptors of cullin 5 Ring E3 ubiquitin ligase. Nonetheless, the mechanism of substrate recognition by ASB family proteins has remained largely elusive. Here we present the crystal structure of ASB7-Elongin B-Elongin C ternary complex bound to a conserved helical degron.

although known as "Sweet Tea" (ST), has been traditionally accepted as a daily beverage and used as a folk medicine in southern China with little understanding of its potential toxicity. This study evaluated the safety of a water extract of ST by a subchronic toxicity study in Sprague-Dawley rats. A total of 80 rats were randomized divided into 4 groups with 10 males and 10 females in each group, treated with 2000, 1,000, 500 and 0 mg/kg body weight of ST extract by gavage for 90 days, respectively.

Targeting oncogenic mutant p53 represents an attractive strategy for cancer treatment due to the high frequency of gain-of-function mutations and ectopic expression in various cancer types. Despite extensive efforts, the absence of a druggable active site for small molecules has rendered these mutants therapeutically non-actionable. Here we develop a selective and effective proteolysis-targeting chimera (PROTAC) for p53-R175H, a common hotspot mutant with dominant-negative and oncogenic activity.

Article Synopsis
  • The research studied how different resolutions of data affect understanding spatial scale effects, especially related to nitrogen removal in wetlands.
  • In 2018, researchers analyzed how nitrogen levels changed across different resolutions and found that a resolution 25 times the original was significant.
  • The study concluded that simply changing the resolution didn't greatly alter the overall pattern, but it was important to look at various resolutions when examining these effects.

Introduction: Nuclear undecaprenyl pyrophosphate synthase 1 (NUS1) gene variants are associated with a range of phenotypes, including epilepsy, intellectual disability, cerebellar ataxia, Parkinson's disease, dystonia, and congenital disorders of glycosylation. Additionally, cases describing genotypes and clinical features are rare.

Case Presentation: Herein, we report the case of a 23-year-old Chinese female patient who presented with tremors, intellectual disability, and epilepsy.

Objectives: This study aimed to investigate the correlations between carotid intima-media thickness (IMT) and systemic immune inflammation index (SII), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte (NLR) ratio.

Materials And Methods: This was a cross-sectional study enrolling a total of 582 middle-aged and elderly patients. The correlations between SII, PLR, and NLR with IMT were assessed using logistic regression models, which were subsequently incorporated into the underlying models with traditional risk factors and their predictive values for IMT.

Nitrogen-doped molybdenum trioxide (MoO/NC) has drawbacks such as volume expansion during long-term charging and discharging cycles, which severely limit its further application. This work proposes the addition of titanium dioxide nanoparticles (TiO NPs) for performance improvement of MoO/NC. TiO NPs embedded on the surface of a MoO/NC nanosheet can alleviate its volume expansion and the accumulation of lithiated products and improve the conductivity of the electrode material.

Breast cancer is considered the most prevalent malignancy due to its high incidence rate, recurrence, and metastasis in women that makes it one of the deadliest cancers. The current study aimed to predict the genes associated with the recurrence and metastasis of breast cancer and to validate their effect on MDA-MB-231 cells. Through the bioinformatics analysis, the transcription factor 7 cofactor (MLLT11) as the target gene was obtained.

Previous evidence has demonstrated that elevated low-density lipoprotein cholesterol (LDL-C) was associated with atherosclerosis. However, there is scarce population-based evidence for the role of remnant cholesterol (remnant-C) in arterial stiffness, an imaging marker for subclinical atherosclerosis. Herein, we aimed to evaluate the correlation of remnant-C with arterial stiffness beyond LDL-C in a check-up population.

Purpose: To determine whether the morphological parameters of prostate zones and tumors on magnetic resonance imaging (MRI) can predict the tumor-stage (T-stage) of prostate cancer (PCa) and establish an optimal T-stage diagnosis protocol based on three-dimensional reconstruction and quantization after image segmentation.

Methods: A dataset of the prostate MRI scans and clinical data of 175 patients who underwent biopsy and had pathologically proven PCa from January 2018 to November 2020 was retrospectively analyzed. The authors manually segmented and measured the volume, major axis, and cross-sectional area of the peripheral zone (PZ), transition zone, central zone (CZ), anterior fibromuscular stroma, and tumor.

BiSe is a promising cathode material for aqueous zinc ion batteries (AZIBs), but its limited capacity and poor cycling stability deter its further use in the development of AZIBs. To solve this issue, BiSe/NCD composites have been synthesized a simple two-step solvothermal method. The introduction of nitrogen-doped carbon dots (NCDs) provides more active sites and makes the composite surface rich in functional groups, which facilitates contact with aqueous electrolytes.
