Understanding the impact of parental involvement subtypes on Chinese preschool children's language ability.

Parental involvement, especially home-based involvement and home‒school communication, is an important factor affecting the development of preschool children's language abilities. Although previous studies suggest that parents are important catalysts in shaping children's language achievement, it is still unclear how types of parental involvement affect children's language abilities. This study surveys 874 preschool children in China and finds that home-based involvement boosts children's language abilities via improved approaches to learning.

Benzoxazine: A Privileged Scaffold in Medicinal Chemistry.

Background: Benzoxazine is one of the most important privileged scaffolds in medicinal chemistry. Compounds bearing benzoxazine moiety usually have a variety of biological activities, such as anti-inflammatory, anti-microbial, anti-tuberculosis, anti- oxidant and anti-cancer activities. The fascinating bioactivity profile of benzoxazine scaffold in various fields has prompted medicinal chemists to design and discover novel benzoxazine derivatives as potential therapeutic candidates with the desired biological properties.

Tumor mutational burden is associated with poor outcomes in diffuse glioma.

Background: Tumor mutational burden (TMB) is a potential biomarker for immune checkpoint therapy and prognosis. The impact of TMB on clinical outcomes and the correlation coefficient between exome sequencing and targeted sequencing in glioma have not yet been explored.

Methods: Somatic mutations in the coding regions of 897 primary gliomas and the clinical and RNA-seq data of 654 patients in The Cancer Genome Atlas (TCGA) database were analyzed as a training set, while another 286 patients in the Chinese Glioma Genome Atlas (CGGA) database were used for validation.

Zyxin (ZYX) promotes invasion and acts as a biomarker for aggressive phenotypes of human glioblastoma multiforme.

Glioblastoma multiforme (GBM) is characterized by highly invasive growth, which leads to extensive infiltration and makes complete tumor excision difficult. Since cytoskeleton proteins are related to leading processes and cell motility, and through analysis of public GBM databases, we determined that an actin-interacting protein, zyxin (ZYX), may involved in GBM invasion. Our own glioma cohort as well as the cancer genome atlas (TCGA), Rembrandt, and Gravendeel databases consistently showed that increased ZYX expression was related to tumor progression and poor prognosis of glioma patients.

The landscape of immune microenvironment in lung adenocarcinoma and squamous cell carcinoma based on PD-L1 expression and tumor-infiltrating lymphocytes.

Aims: The aim of this study was to investigate the tumor microenvironment immune types (TMIT) based on tumor cell programmed cell death ligand 1 (PD-L1) expression and tumor-infiltrating lymphocytes (TILs) distribution and whether distinct TMIT subtypes (TMIT I, PD-L1 /TIL ; TMIT II, PD-L1 /TIL ; TMIT III, PD-L1 /TIL ; and TMIT IV, PD-L1 /TIL ) differentially affect clinical outcomes of patients with lung adenocarcinoma (LAC) and squamous cell carcinoma (SCC).

Methods And Results: Immunohistochemistry (IHC) was applied to evaluate the expression of PD-L1 and the spatial distribution of programmed cell death 1 (PD-1) and CD8 TILs on the surgically resected specimens from 205 cases of LAC and 149 cases of SCC. PD-1 and CD8 TILs were more frequently distributed in SCC than those in LAC, regardless of their infiltrating in the tumor islets or stroma.

Phosphorylated mTOR and YAP serve as prognostic markers and therapeutic targets in gliomas.

Glioma is the most prevalent type of tumor in the brain and is comprised of grades I-IV, according to the WHO classification system. Grade IV glioma is also known as glioblastoma multiforme (GBM), the most malignant type of glioma. Glioma is characterized by a complex molecular background, and gene profiling studies have disclosed critical genetic events in human gliomas, which make targeted therapies the most promising therapeutic strategy.

Poly lactic-co-glycolic acid controlled delivery of disulfiram to target liver cancer stem-like cells.

Disulfiram (DS), an anti-alcoholism drug, shows very strong cytotoxicity in many cancer types. However its clinical application in cancer treatment is limited by the very short half-life in the bloodstream. In this study, we developed a poly lactic-co-glycolic acid (PLGA)-encapsulated DS protecting DS from the degradation in the bloodstream.
