While the energy of a photon passes through the target, the energy of a proton is deposited at a certain depth, which in turn is negligible beyond this stopping point (i.e., the “Bragg peak”). In addition, the proton beam has a 10% higher biological effect in the same dose than the photon beam. Recent technological advances have led to wide use of proton therapy in clinical practice. To date, more than 170,000 patients have received proton therapy. Although clinical experience with proton therapy is increasing now, only approximately 1% of all radiation therapy recipients receive proton therapy and prospective randomized studies involving large sample populations remain very limited yet. The aim of this review is to describe the physical and biological properties of proton therapy and discusses the clinical evidence supporting proton therapy in various disease sites.","PeriodicalId":42462,"journal":{"name":"Precision and Future Medicine","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48285344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their characteristics and prognosis are difficult to discern. There is currently an emphasis on microRNAs (miRNA) as candidate biomarkers for glial tumors. The aim of this study is to identify the specific miRNA patterns in glial tumors by using peptide nucleic acid (PNA)based microarrays in an assortment of glial tumors and normal tissue samples. Methods: Sample files were retrospectively assessed for cases diagnosed as glial tumors at the pathological archives of two institutes. miRNAs of 28 cases of glial tumors were analyzed by microarray. In order to verify the results, quantitative real-time polymerase chain reaction (RT-PCR) was performed. miRNA expression was calculated using the 2 method. The expression level of the miRNAs was compared using SPSS version 20.0 (IBM Co.). Results: miRNA expression profiling of glial tumors revealed that 62 miRNAs were detected from glioblastoma and benign brain tissue, with different expression patterns. The expression of miR-296-3p, miR-370, and miR-371-5p was shown to be involved in malignancy. These miRNAs were also increased in the glioblastoma with methylated O6-methyguanine DNA methyltransferase. The expression pattern of miR-296-3p shows same tendency in PNA-based microarray and RT-PCR. Conclusion: These analyses suggest that novel miRNAs can be applicable as diagnostic tools and target therapeutic agents, since miRNAs can positively or negatively regulate glioblastomas.","PeriodicalId":42462,"journal":{"name":"Precision and Future Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42282371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regulatory frameworks throughout the stem cell market have been concurrently established, which will encourage the advent of a variety of stem cell products in our society. Given the circumstances, stem cell bioprocessing has emerged as one of the most critical fields of research to address a number of issues that currently exist in manufacturing clinical-grade stem cells at an industrial scale. Highly specialized bioreactor designs are at the center of essentially required technologies in the field of stem cell bioprocessing, which ultimately aim for automated, standardized, traceable, cost-effective, safe, and regulatory-compliant manufacture of stem cell-based products. In this review, recently developed bioreactor designs to introduce important regulatory factors to three-dimensional stem cell culture are exemplified, and prerequisites for the ideal bioreactor systems for stem cell bioprocessing are discussed.","PeriodicalId":42462,"journal":{"name":"Precision and Future Medicine","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48021529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In more than 95% of CML, the fusion occurs in the major breakpoint cluster region (M-bcr) of BCR, most commonly producing the e14a2 or e13a2 type. CML with e1a2 BCR-ABL1 by fusion in minor bcr is rare, accounting for approximately 1% of CML. CML with e1a2 BCR-ABL1 is reportedly associated with monocytosis and poor prognosis. Here we describe a woman who underwent bone marrow (BM) study with an impression of chronic myelomonocytic leukemia based on thrombocytosis and prominent monocytosis. Genetic workup revealed, however, t(9;22) and e1a2 BCR-ABL1, which indicated CML and explained her unusual monocytosis. A review of serial complete blood counts (CBC) before the BM study demonstrated that isolated monocytosis preceded the abnormalities in other parameters of CBC. The patient is on follow-up with tyrosine kinase inhibitor (TKI, dasatinib) medication. Close monitoring is required due to the association of e1a2 BCR-ABL1 with poor response to TKI and frequent disease progression. Timely genetic workup and determination of the precise type of BCR-ABL1 transcripts are critical for the diagnosis and stratification of this rare subtype of CML with distinct genotype-phenotype correlations.","PeriodicalId":42462,"journal":{"name":"Precision and Future Medicine","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45187717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has a significant impact on populations and is characterized by chronically disturbed sleep and sleep loss, non-refreshing sleep, and heightened arousal in bed. Poor sleep is associated with a wide range of negative health outcomes, and it is reported that poorer quality of life and medical, neurological, and psychiatric comorbidities disrupt sleep. Sleep difficulties may result from multiple etiologies; however, the neurobiological mechanisms underlying chronic insomnia disorder are not sufficiently understood. Recently, numerous neuroimaging studies have been conducted to investigate the structural or functional derangement in the brains of patients with chronic insomnia disorder. The development of neuroimaging techniques has provided insight into the pathophysiological mechanisms that make patients with chronic sleep disturbances vulnerable to cognitive impairment.","PeriodicalId":42462,"journal":{"name":"Precision and Future Medicine","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44004163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: In this prospective, multicenter, phase III trial, we randomly assigned patients to three treatment arms: patients who receive adjuvant S-1 for 1 year, S-1 plus oxaliplatin (SOX) for 6 months, or SOX plus chemoradiotherapy (SOXRT). Herein, we report the safety outcomes of patients who received adjuvant chemotherapy or chemoradiotherapy. Results: Among a total of 514 patients registered between February 2013 and December 2017, 499 patients who either completed or discontinued the assigned study treatments were included in the present analysis. All the three treatment arms were generally well-tolerated, with the overall treatment completion rate of 94% (96% in S-1, 93% in SOX, and 92% in SOXRT). The median delivered dose of radiotherapy in the SOXRT arm was 4,500 cGy (range, 0 to 4,500 cGy). The most frequently observed adverse events were fatigue (29%) in S-1 arm and peripheral neuropathy in the SOX and SOXRT arms (59% and 50%, respectively).
