Compact proton therapy for fight against cancer

The future face of modern-day anti-cancer therapy based on charged particles like protons could potentially involve using laser accelerators. However, these facilities will need to be reduced in terms of both size and cost compared to conventional ones. A medical physicist is the first to present a new design for the entire complex machine – from the accelerator to the radiation site. In the process, he has successfully cut the facility's size in half.

Authors: Saud B, Paudel G Abstract Air pollution has been a major problem of 21st century for both developed and developing world. It has a negative impact on various environmental aspects which directly or indirectly affect the quality of human health. Nepal, especially Kathmandu, in the current situation, is observing rapid urbanization and various infrastructure development projects. As a result, these sorts of human activities have been responsible for increasing air pollution in an enormous rate inside Kathmandu Valley. Chronic exposure of deteriorated air increases the chance of Noncommunicable Disease (NCD) ...

Advanced stage neuroblastoma is a very aggressive pediatric cancer with limited treatment options and a high mortality rate. Glycogen synthase kinase-3β (GSK-3β) is a potential therapeutic target in neuroblastoma. Using immunohistochemical staining, we observed positive GSK-3β expression in 67% of human neuroblastomas (34 of 51 cases). Chemically distinct GSK-3 inhibitors (AR-A014418, TDZD-8, and 9-ING-41) suppressed the growth of neuroblastoma cells, whereas 9-ING-41, a clinically relevant small-molecule GSK-3β inhibitor with broad-spectrum preclinical antitumor activity, being the most potent. Inhibit...

Long noncoding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) functions as a crucial regulator of metastasis in lung cancer. The aim of this study is to unravel the underlying mechanisms of lncRNA MALAT1 in non-small-cell lung cancer (NSCLC). A cohort of 36 NSCLC tumor tissues and adjacent normal tissues was collected postoperatively from patients with NSCLC. qRT-PCR was performed to detect the expression of MALAT1 in both NSCLC tissues and cell lines. Cell migration and invasion were monitored by wound healing assay and transwell invasion assay. Western blot was used to detect the expression ...

In this study, MAP30, a ribosome-inactivating protein reported to have apoptotic effects on cancer cells, was fused with S3, an epidermal growth factor receptor (EGFR)-targeting peptide. In addition, CsA was used to investigate whether it can further promote the apoptotic effects of S3 fused MAP30 (MAP30–S3). Our result showed that the internalization of FITC-labeled MAP30–S3 was increased significantly by S3 in HeLa cells. Unexpectedly, MAP30–S3 only showed a minor decrease in the viability of EGFR-overexpressing cancer cells, including HeLa, SMMC-7721, and MGC803 (IC50>5 μmol/l). However, 2...

In this study, we showed that celastrol combined with EGFR-TKIs significantly suppressed cell invasion of lung cancer cells with a T790M mutation by suppressing the EGFR pathway. Combined therapy with celastrol and EGFR-TKIs inhibited tumor growth in vivo. Together, these results suggested that combined therapy with EGFR-TKIs and celastrol may be a more effective treatment of patients with non-small-cell lung cancer with T790M mutations of the EGFR.

To investigate effect of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on epithelial-to-mesenchymal transition (EMT) of esophageal cancer (EC) and role of enhancer of zeste homolog 2 (Ezh2)-Notch1 signaling pathway in the process. The expression of MALAT1 was determined in four EC cell lines by real-time PCR. TE-1 and EC109 cells were transfected with sh-MALAT1 to inhibit expression of MALAT1 or transfected with pcDNA3.1-Ezh2 to overexpress Ezh2. Invasion and migration assays were conducted to analyze cell metastasis, and expressions of Ezh2-Notch1 signaling-related proteins as well as ...
