BACKGROUND Synchronous primary neoplasms have been encountered in some patients with mucosal squamous cell carcinoma of the head and neck. Routine panendoscopy along with various radiological tests have been advocated to identify these potential tumors. In 1993, we originally described symptom-directed, selective endoscopy as an efficient and cost-effective means to evaluate patients to identif...
Finding accurate methods to be employed for the treatment of esophageal cancers is of especial interest for researchers, due to the sensitivity of this tissue. Recently radioactive stents loaded with I-125 brachytherapy seeds have been widely investigated for the treatment of advanced esophageal cancer. It is necessary to investigate the dose distribution of any radioactive esophageal stents be...
Background The benefits of vitamin E (VE) for multiple health outcomes have been well evaluated in many recent studies. Objective purpose this umbrella review was to conduct a systematic evaluation the possible associations between VE intake and various outcomes. Methods We systematically searched databases, such as PubMed, Embase, Web Science, identify related meta-analyses observational studi...
The differential diagnosis of masses in the posterior mediastinum includes neurogenic neoplasms, cysts, esophageal tumors, infectious processes including abscesses, and disorders of the thoracic spine. Nonoperative procedures, including transcutaneous and transbronchial biopsies and thoracoscopy, may not lead to a definitive diagnosis. We present two cases in which a neurogenic tumor, with and ...
The incidence of esophageal cancer in Kazakhstan was analysed for the period of 1989-2010 years, with a focus on trends by age, gender and region. The highest rates of incidence were evident in the Western regions. The dynamics for cancer of the esophagus in the Republic demonstrated decrease, except in the Karaganda region, where a tendency for increase was noted. Considerable variation betwee...
Endoscopic submucosal dissection (ESD) requires a high skill level due to poor visualization and instability in the cutting area. Mucosal flap formation after beginning submucosal dissection is the most difficult part of the procedure but improves visibility in the cutting area and allows for easier dissection, because the mucosal flap can be lifted with an attachment fitted to the endoscope. A...
Background and purpose: Cancer is the one common cause of death in developed and the developing countries. Still gastrointestinal cancers is a major cause of Deaths from cancerin the north of the IRAN, this part is a place that located on the Esophageal Cancer belt. As well as is one of esophageal cancer focuses in the world. At the north east of IRAN such as TORKAMAN SAHRA that reaches a maxim...
PBMDA: A novel and effective path-based computational model for miRNA-disease association prediction
In the recent few years, an increasing number of studies have shown that microRNAs (miRNAs) play critical roles in many fundamental and important biological processes. As one of pathogenetic factors, the molecular mechanisms underlying human complex diseases still have not been completely understood from the perspective of miRNA. Predicting potential miRNA-disease associations makes important c...
BACKGROUND The urokinase plasminogen activation system is associated with metastatic potential of cancer in several tumors. Its specific membrane receptor (uPAR) is released from cancer cells and can be detected as the soluble fraction of the plasminogen activator receptor (suPAR). Ferritin (FRT) is a poor prognostic factor in various neoplasms. OBJECTIVES We analyzed the serum concentrations...
