Aberrant glycosylation expressed in specific types of human cancer may define stage, direction, and fate of tumor progression. Well-studied examples are expression of sialosyl-Lewis(x) or sialosyl-Lewis(a) in colorectal carcinoma and histo-blood group A and H/Le(y) in lung cancer. In renal cell carcinoma (RCC), expression of sialosyl-Lewis(x) has no correlation with metastatic potential. Clinic...

Objectives The assessment of oxidative stress (OS) in serum relapsing-remitting multiple sclerosis patients treated with II-line immunomodulatory therapy (fingolimod, natalizumab) compared to newly diagnosed patients (de novo group) treated with interferon (IFN) beta and controls. The relationship between OS parameters and gender, age, disease duration, Expanded Disability Status Scale, annuali...

Anxiety can be an adaptive response to potentially threatening situations. However, if experienced in inappropriate contexts, it can also lead to pathological and maladaptive anxiety disorders. Experimentally, anxiety can be induced in healthy individuals using the threat of shock (ToS) paradigm. Accumulating work with this paradigm suggests that anxiety promotes harm-avoidant mechanisms throug...

BACKGROUND Several randomised clinical trials (RCTs) of analgesics in postoperative pain after traumatic or orthopaedic surgery (TOS) have been published, but no studies have assessed the quality of these reports. We aimed to examine the quality of reporting RCTs on analgesics for postoperative pain after TOS. METHODS Reports of RCTs assessing analgesics in postoperative pain after TOS were s...

During revision surgical fixation of clavicle fractures and fracture nonunions, compression of the prominent neurovascular structures of the thoracic outlet can be an important potential complication. In this report, we describe the case of a manual laborer who had iatrogenic compression of the thoracic outlet of his dominant arm by fracture callus during revision surgery after multiple subacut...

BACKGROUND Transoral surgery (TOS) for patients with early stage oropharyngeal squamous cell carcinoma (SCC) is increasingly used, however, criticized, because of less optimal access to the tumor than open techniques and thus potentially jeopardizing tumor control in comparison with radiotherapy (RT). Therefore, we compared the currently available data on survival provided by TOS versus RT. M...

INTRODUCTION Ulcerative colitis (UC) is a fairly common chronic inflammatory disorder. Chronic inflammation may contribute to the risk of colorectal cancer through the accumulation of specific products resulting from DNA damage. Previous studies reported that DNA damage and oxidative stress play a significant role in the pathophysiology of UC, but the results are inconsistent. OBJECTIVES In t...

This research aims to measure the awareness and the implementation of tour operators (TOs) regarding to sustainable tourism supply chain management (STSM) and to explore the internal factors of TOs affecting their STSM implementation. The qualitative data obtained from interviewing with stakeholders and quantitative data collected from the survey of 130 tour operators in Chiangmai and Phuket pr...

The use of a mathematical model of cerebral physiology and metabolism may aid the interpretation of experimentally measured data. In this study, model outputs of tissue oxygen saturation (TOS) and velocity of blood in the middle cerebral artery (Vmca) were compared with experimentally measured signals (TOS using near infrared spectroscopy and Vmca using transcranial Doppler) acquired during hyp...

BACKGROUND Essential thrombocythemia (ET) is a clonal disease in which thrombotic and hemorrhagic complications are common. Our aim in this study was to investigate whether oxidative stress in ET patients increased compared to healthy volunteers and to investigate whether there is a relationship between vascular events and oxidative status parameters in ET patients. PATIENTS AND METHODS We de...
