Robust Autism Spectrum Disorder-Related Spatial Covariance Gray Matter Pattern Revealed With a Large-Scale Multi-Center Dataset.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder and its underlying neuroanatomical mechanisms still remain unclear. The scaled subprofile model of principal component analysis (SSM-PCA) is a data-driven multivariate technique for capturing stable disease-related spatial covariance pattern. Here, SSM-PCA is innovatively applied to obtain robust ASD-related gray matter volume pattern associated with clinical symptoms.

[Research Advances of Exosomes in Pathogenesis of Multiple Myeloma --Review].

Research on the participation of exosomes in pathogenesis and prognosis of multiple myeloma (MM) has made encouraging progress. However, the specific mechanism has not yet been clarified. Recently, domestic and foreign researchers have pressed forward on deeper study on exosomes.

The lncRNA CADM2-AS1 promotes gastric cancer metastasis by binding with miR-5047 and activating NOTCH4 translation.

Background: Multi-organ metastasis has been the main cause of death in patients with Gastric cancer (GC). The prognosis for patients with metastasized GC is still very poor. Long noncoding RNAs (lncRNAs) always been reported to be closely related to cancer metastasis.

A systematic review of transcranial magnetic stimulation treatment for autism spectrum disorder.

Autism spectrum disorder (ASD) is a behaviorally defined complex neurodevelopmental syndrome characterized by persistent social communication and interaction deficit. Transcranial magnetic stimulation (TMS) is a promising and emerging tool for the intervention of ASD by reducing both core and associate symptoms. Several reviews have been published regarding TMS-based ASD treatment, however, a systematic review on study characteristics, specific stimulating parameters, localization techniques, stimulated targets, behavioral outcomes, and neuroimage biomarker changes is lagged behind since 2018.

Impaired segregation of the attention deficit hyperactivity disorder related pattern in children.

Background: Inattention is a key characteristic of attention deficit hyperactivity disorder (ADHD). Specific brain abnormalities associated with this symptom form a discernible pattern related with ADHD in children (i.e.

Abnormal functional connectivity of the reward network is associated with social communication impairments in autism spectrum disorder: A large-scale multi-site resting-state fMRI study.

Background: The social motivation hypothesis proposes that the social deficits of autism spectrum disorder (ASD) are related to reward system dysfunction. However, functional connectivity (FC) patterns of the reward network in ASD have not been systematically explored yet.

Methods: The reward network was defined as eight regions of interest (ROIs) per hemisphere, including the nucleus accumbens (NAc), caudate, putamen, anterior cingulate cortex (ACC), ventromedial prefrontal cortex (vmPFC), orbitofrontal cortex (OFC), amygdala, and insula.

[Effect of Dimethyl Fumarate (DMF) on T-cell Acute Lymphoblastic Leukemia].

Objective: To explore the effect and possible mechanism of dimethyl fumarate (DMF) on T-cell acute lymphoblastic leukemia (T-ALL), and provide experimental and theoretical basis for the clinical treatment of T-ALL.

Methods: Jurkat cells were treated with different concentrations of DMF for 24 hours, and then the proportion and absolute count of Ki67-positive Jurkat cells were analyzed by flow cytometry. Meanwhile, the protein levels of nuclear factor-erythroid 2-related factor 2 (Nrf2) and E3 ubiquitin ligase HACE1 in Jurkat cells treated with DMF for 24 hours were evaluated by Western blot.

Progress in the development of small molecular inhibitors of the Bruton's tyrosine kinase (BTK) as a promising cancer therapy.

Bruton tyrosine kinase (BTK) is a key kinase in the B cell antigen receptor signal transduction pathway, which is involved in the regulation of the proliferation, differentiation and apoptosis of B cells. BTK has become a significant target for the treatment of hematological malignancies and autoimmune diseases. Ibrutinib, the first-generation BTK inhibitor, has made a great contribution to the treatment of B cell malignant tumors, but there are still some problems such as resistance or miss target of site mutation.

The design, synthesis and anti-tumor mechanism study of new androgen receptor degrader.

Targeted protein degradation using small molecules is a novel strategy for drug development. In order to solve the problem of drug resistance in the treatment of prostate cancer, proteolysis-targeting chimeras (PROTAC) was introduced into the design of anti-prostate cancer derivatives. In this work, we synthesized two series of selective androgen receptor degraders (SARDs) containing the hydrophobic degrons with different linker, and then investigated the structure-activity relationships of these hybrid compounds.

2,4-Disubstituted quinazolines targeting breast cancer cells via EGFR-PI3K.

A series of novel 2,4-disubstituted quinazolines were synthesized and evaluated for their anti-tumor activity against five human cancer cells (MDA-MB-231, MCF-7, PC-3, HGC-27 and MGC-803) using MTT assay. Among them, compound 9n showed the most potent cytotoxicity against breast cancer cells. Compound 9n also significantly inhibited the colony formation and migration of MDA-MB-231 and MCF-7 cells.

Synthesis and anticancer activities of novel 1,2,4-triazolo[3,4-a]phthalazine derivatives.

Trying to develop potent and selective anticancer agents, two series of novel 1,2,4-triazolo[3,4-a]phthalazine derivatives were designed and synthesized. Their antitumor activities were evaluated by MTT method against four selected human cancer cell lines (MGC-803, EC-9706, HeLa and MCF-7). Our results showed that compound 11h exhibited good anticancer activities compared to 5-fluorouracil against the four tested cell lines, with IC50 values ranging from 2.
