Garlic polysaccharides is one of the important effective components of garlic, which has various bioactivities, including immune-enhancing, hepatoprotective, and antioxidant. Garlic polysaccharides is mainly composed of monosaccharides, such as Fru, Glc, and Gal, having a (2 → 1)-linked β-D-Fruf backbone with (2 → 6)-linked β-D-Fruf side chains.

Understanding the molecular mechanisms involved in DLBCL is important to identify new therapeutic targets. The present study aimed to screen and identify differentially expressed microRNAs (miRNAs/miRs) between diffuse large B-cell lymphoma (DLBCL) and control [lymph node reactive hyperplasia (LRH)] groups, and to investigate whether miRNAs associated with DLBCL could serve as potential therapeutic targets.

The molecular pathogenesis of PTCL remains unknown. In this study, we chose the gene expression profile of GSE6338 from the Gene Expression Omnibus (GEO) database to identify hub genes and key pathways and explore possible molecular pathogenesis of PTCL by bioinformatic analysis.

Herein, first-principle calculations are used to construct and investigate the electronic and interfacial properties of 2D MoTe in contact with a graphene electrode by taking full advantage of them. The obtained results reveal that the electronic properties of graphene and MoTe layers are well preserved in heterostructures due to the weak van der Waals interlayer interaction, and the Fermi level moves toward the conduction band minimum of MoTe layer thus forming an n type Schottky contact at the interface.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease with unclear pathogenesis. DLBCL accounts for 30%-35% of all non-Hodgkin lymphomas (NHLs) and is an aggressive subtype of mature B-cell neoplasm. At present, half of DLBCL cases can be cured, although one-third of patients experience recurrence after treatment and enter advanced tumor stage.
