Perinatal and early life risk factors for childhood brain tumors: Is instrument-assisted delivery associated with higher risk?

ConclusionsPerinatal and early-life risk factors, and specifically indicators of brain trauma, exposure to toxic agents and immune system maturation, might be involved in the pathogenesis of childhood brain tumors. Larger studies should aim to replicate our findings and examine associations with tumor subtypes.

Gliomas account for approximately 80% of primary malignant tumors in the central nervous system. Despite aggressive therapy, the prognosis of patients remains extremely poor. Glioma stem cells (GSCs), considered a potential target of therapy for their crucial role in therapeutic resistance and tumor recurrence, are believed to be key factors in the disappointing outcome. Here, we took advantage of GSCs as the cell model to perform high-throughput drug screening, and the old antibiotic clofoctol was identified as the most effective compound, showing reduction of colony formation and induction of apoptosis of GSCs. Moreover,...

AbstractA novel series of coumarin-pyridine/fused pyridine hybrids were designed and synthesized. Their anticancer activity was evaluated against human cancer cell lines MCF-7, HCT-116, HepG-2, and A549. Compounds9,10, and11 showed the most potent growth inhibitory activities with IC50 values ranging from 1.1 to 2.4  μM, against MCF-7 cell line. Flow cytometric analysis revealed that these compounds induced cell cycle arrest in the G2/M phase followed by apoptotic cell death. Consistent with these results, the activity of caspase-3 in MCF-7 cells was tested. The results indicated that compounds9,10, and11 increas...

Contributors : Rui Kuang ; Wei ZhangSeries Type : OtherOrganism : Homo sapiensThe NanoString experiment were conducted on 59 cell lines including 12 ovary cell lines, 12 lung cell lines, 11 colon cell lines, 10 breast cell lines, 4 pancreas cell lines, 2 prostate cell lines, 2 stomach cell lines, and 6 cell lines of 6 other types of tissues. A total of 403 probes were customized to estimate the isoform expressions of 155 cancer genes curated from the literature with more reliable isoform annotations, where each of the 155 gene contains at least two isoforms.

ConclusionsManagement of patients with advanced rectal cancer and radiologically positive lateral pelvic lymph nodes is challenging due to high local recurrence rates. Further studies are needed to develop care pathways for the optimal treatment processes.

ConclusionTest sensitivity, test frequency and out-of-pocket cost were the key factors influencing surveillance uptake. Patients prefer a test with the highest sensitivity, offered frequently, that incurs no upfront costs.

ConclusionsIn this large institutional analysis, while LG for GC was associated with DSS and DFS similar to those for OG overall, non-inferior LG-associated survival especially DSS was observed in some subgroups rarely investigated in prospective or randomized settings. There could still be biases even after PSM due to confounders not accounted for in this observational study. However, these findings offer novel hypotheses for further validation.
