Paclitaxel-induced cognitive decline was attenuated by necroptosis inhibition.

Anti-cancer agent paclitaxel induces cognitive impairment. Paclitaxel can induce limited neuron apoptosis and wide scope of neuroinflammation, but its precise mechanisms remain unclear. In this study, we determined paclitaxel causes necroptosis, a programmed cell death, via activation of the RIPK1-RIPK3-MLKL signaling pathway in hippocampal neurons (HT22 cells).

The recent progress of bone regeneration materials containing EGCG.

Epigallocatechin-3-gallate (EGCG) is the most effective active ingredient in tea polyphenols and belongs to the category of catechins. EGCG has excellent antioxidant activity, anti-inflammatory, osteogenesis-promoting, and antibacterial properties, and has been widely studied in orthopedic diseases such as osteoporosis. To reach the lesion site, achieve sustained release, promote osteogenesis, regulate macrophage polarization, and improve the physical properties of materials, EGCG needs to be cross-linked or incorporated in bone regeneration materials.

Study Design, Setting, And Sample: The investigators designed a retrospective cohort study.

Recent Advances in Cell Sheet-Based Tissue Engineering for Bone Regeneration.

In conventional bone tissue engineering, cells are seeded onto scaffolds to create three-dimensional (3D) tissues, but the cells on the scaffolds are unable to effectively perform their physiological functions due to their low density and viability. Cell sheet (CS) engineering is expected to be free from this limitation. CS engineering uses the principles of self-assembly and self-organization of endothelial and mesenchymal stem cells to prepare CSs as building blocks for engineering bone grafts.

The Role of Macrophage Phenotype in the Vascularization of Prevascularized Human Bone Marrow Mesenchymal Stem Cell Sheets.

With the development of tissue engineering and regenerative medicine, prevascularized bone marrow mesenchymal stem cell (BMSC) sheets have been regarded as a promising method for tissue regeneration. Furthermore, the inflammatory response is one of the main regulators of vascularization and the restoration of engineered tissue function; among them, macrophages and cytokines produced by them are considered to be the decisive factors of the downstream outcomes. This study investigated the effect of macrophages on the formation of microvascular-like structures of human umbilical vein endothelial cells (HUVECs) in BMSC sheets.

Background: Both apatinib and programmed death 1 (PD-1) monoclonal antibody (mAb) monotherapy have been licensed in China for the third-line treatment of advanced gastric cancer (AGC). However, whether the combination could improve the prognosis of patients with AGC after second-line treatment has not been evaluated.

Methods: We retrospectively screened 892 patients with AGC who received third-line or later treatment from June 2016 to July 2021 at the Affiliated Cancer Hospital of Zhengzhou University and second People's Hospital of Pingdingshan.

Genetic deconvolution of fetal and maternal cell-free DNA in maternal plasma enables next-generation non-invasive prenatal screening.

Current non-invasive prenatal screening (NIPS) analyzes circulating fetal cell-free DNA (cfDNA) in maternal peripheral blood for selected aneuploidies or microdeletion/duplication syndromes. Many genetic disorders are refractory to NIPS largely because the maternal genetic material constitutes most of the total cfDNA present in the maternal plasma, which hinders the detection of fetus-specific genetic variants. Here, we developed an innovative sequencing method, termed coordinative allele-aware target enrichment sequencing (COATE-seq), followed by multidimensional genomic analyses of sequencing read depth, allelic fraction, and linked single nucleotide polymorphisms, to accurately separate the fetal genome from the maternal background.

Acupuncture combine with Tuina for diabetic peripheral neuropathy: A protocol for a systematic review and meta-analysis.

Background: Diabetic peripheral neuropathy (DPN) is one of the most common microvascular complications of diabetes mellitus, with an incidence ranging from 60% to 90%. With the change in modern dietary structure, the incidence of diabetes is increasing year by year, and DPN is also on the rise. Acupuncture and Tuina treatments are often combined to treat DPN; however, there has been no meta-analysis on their synergistic effect; therefore, we aimed to perform a systematic review and meta-analysis to estimate the effectiveness of acupuncture combined with Tuina in DPN treatment.

Osimertinib Rechallenge With Bevacizumab vs. Chemotherapy Plus Bevacizumab in EGFR-Mutant NSCLC Patients With Osimertinib Resistance.

At present, treatment options for osimertinib resistance are very limited. Dual inhibition of the vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) significantly improved the progression-free survival (PFS) of advanced EGFR-mutant non-small cell lung cancer (NSCLC). After EGFR-tyrosine kinase inhibitor (TKI) resistance, EGFR-TKI continuation combined with VEGF inhibitors still had clinical benefits.
