Filter by:The mortality rate of oral cancer in Taiwan is still high with no decrease. One of the reasons result in these situations is the patent visits hospital for treatment in late stage of oral cancer. Recently, the government makes effort in oral cancer screening to find oral potentially malignant disorders (OPMD) early. However, there is no conscience in treatment strategies of OPMD up to now. In this study, we will set a OPMD data bank, and use the cases to find out the potential biomarker, which is able to predict the oral cancer malignant transformation. Sixty OPMD with oral cancer transformation will be recruited, and 60 OPMD with no oral cancer malignant transformation will also be enrolled as the disease control group. Besides, 20 normal cases and 60 oral cancer cases resulting from previous OPMD will be collected. All those groups will detect the expression of p62/SQSTM1 to investigate the possibility that p62/SQSTM1 as a biomarker to predict the malignant transformation of OPMM, and a guideline to treat or not to treat OPMD.
The purpose of this study is to test whether transcranial direct current stimulation (tDCS) can enhance the clinical efficacy of trauma-focused therapy for posttraumatic stress disorder.
To determine the effect of Activation Mist (AM) on skin wrinkles and appearance.
This study aims to find out if AES ( Activation Energy Serum) , a blend of natural minerals , is effective and safe for the treatment of asthma if taken for 4 weeks . The efficacy will be scientifically tested by symptoms scores, questionnaires, breathing and blood tests.
High-quality bowel preparation is a prerequisite for colonoscopy. Few studies have evaluated visual aids as a means of improving the quality of bowel preparation. We assess the effect of patient-judging dose adjustment of bowel preparation solution for bowel preparation using SMARTPHONE application on the quality of bowel preparation.
The present study explores whether a simultaneously given hepatitis A vaccine (Epaxal) will have an impact on the immune response to PCV13 (pneumococcal conjugate vaccine; Prevenar13) vaccine in adults. The immune response to PCV13 is measured as levels of serotype specific serum antibodies and their opsonophagocytic activity. The results of volunteers receiving PCV13 and Epaxal will be compared to that in a control groups of adults receiving either hepatitis A or PCV13 vaccines only.
Macrophages are derived from monocytes recruited to the tumor site and stimulated by specific chemokines secreted by tumor cells. These tumor associated macrophages (TAMs) have been postulated as being involved in the progression of cancer. Based on our preliminary findings and on published data we hypothesized that macrophage-induced chemoresistance (MIC) can promote survival of pancreatic carcinoma cells during chemotherapy. The overall goal of this study is to evaluate the mechanism of MIC in an in-vitro model of Pancreatic ductal adenocarcinoma (PDA). methods: 1. The human PDA cell line Panc1 will be grown in suitable conditions. 2. Macrophages will be produced by incubating mononuclear cells from the blood of healthy donors in medium with M-CSF for 7 days. 3. TAMs will be generated by culturing these macrophages with tumor-culture conditioning medium (TCCM) of PDA Cells for an additional 72 hours. 4. Human pancreatic cells (PANC1) will be treated with gemcitabine following exposure to macrophages CM. 5. Cell proliferation will be quantified by light microscopy and by an XTT Cell Proliferation Assay Kit.
Some animal studies revealed that the pomegranate juice may improve sperm quality in terms of concentration, motility and morphology, as well as in fertilization rate. Minor data is available regarding the influence on male sperm.
The deep fried chocolate bar is a snack that the international community strongly associates with Scotland. It has previously been cited as being "a symbol of all that is wrong with the high-fat, high-sugar Scottish diet". Despite the snack's reputation, no medical research has been performed to examine the effects of consuming a deep fried chocolate bar on the human body. In contrast to the deep fried chocolate bar, porridge has been shown to reduce the risk of cardiovascular disease, but its effect on cerebral blood flow has yet to be directly assessed. This study will focus on the potential (patho)physiological cerebrovascular effects of the deep fried chocolate bar and porridge. The research question to be addressed in this study is "Does eating a deep fried chocolate bar or bowl of porridge induce changes in cerebral blood flow and cereborvascular reactivity in healthy adults?" To assess the acute effects on eating either food on blood flow through the largest artery in the brain, the investigators will give healthy volunteers one regular-sized deep-fried chocolate bar or a bowl of porridge. Blood flow through the largest artery in the brain will be assessed using simple ultrasounds tests. The investigators aim to recruit 24 volunterrs who will visit twice, consuming a different food on each visit.
The investigators hypothesize that when used by experienced anesthesiologists, Airtraq laryngoscope will increase the first-attempt success rate with shorter intubation times and more stable hemodynamic parameters.
